da tongManufacMobile elevators are generally used in skyscrapers where electric elevators are used, as there is no need to stop midway, so fast elevators are needed. First go to the high-rise sky lobby (high-rise elevator lobby, Skylobby) from the ground, and then transfer to the ordinary elevator to the destination. Some new elevators use elevator pre calling systems, which can pre call designated floors in the lobby. These passenger elevators can be decorated beautifully according to customer needs. Some passenger elevators are also equipped with air conditioning and television, while others are set up in the cabin, so that customers can enjoy the scenery outside while riding.
The correct construction inspection of the airport is to first inspect the foundation to see if there is any water accumulation and to see if the grounding system meets the requirements. We also need to see how the structural bolts of this frame are tightened, and whether there are any cracks in the welds. We need to set them according to the instructions. In mechanical transmission, it can be divided into two types: open type and closed type. Of course, there are also many safety equipment for elevators.
da tong.Whether it is a large machinery with complex structure or a small to medium-sized equipment with simple structure, the maintenance work scope is mainly focused on cleaning, adjustment, fastening, and corrosion prevention, commonly referred to as" Cross homework”.
It is strictly prohibited to connect the motor of the lifting platform to the wrong power supply. It should be ensured that the voltage is 380V or 220V, and daily cleaning work should be carried out. Dust and debris on the motor should be cleaned in a timely manner.
.During use, the elevator should be placed on a solid and flat ground to prevent tipping during operation. Press&quo; Rising; Or&quo; Descending; Press the button to frequently check and maintain the various components of the elevator when lifting the workbench. If the workbench does not move, it should be immediately stopped for inspection. When the working pressure of the electric elevator is found to be too high or the sound is abnormal, it should be immediately shut down for inspection to avoid serious mechanical damage; Regularly check the working status of the shaft pin every month. If any loose shaft pin or screw is found, it is necessary to use and operate the elevator correctly. The operators should receive systematic operation training: regular inspection of operating standards should be conducted, and any violations of the elevator operation should be punished immediately. In severe cases they should be transferred from this position. Since the passing of
Drain all the hydraulic oil in the oil tank, open the oil tank, take out the oil suction filter, clean it,da tongScissor type hydraulic lifting platform, and return it to the oil tank. Install it in its original position. Fill the fuel tank with new oil.
In the construction elevator, the switch box also has leakage protection equipment and its wires and cables have good insulation without leakage. The metal passing through the wires is not rusted, and its damage is close to zero. His steel wire rope should comply with the corresponding configuration requirements, without any issues of strand breakage or shrinkage, and of course, the number of broken wires should not exceed the corresponding standards. His pulley movement is very flexible.
What kind of function can be achieved by installing the elevator? Before installation, confirm whether the motor and elevator are intact, and strictly check whether the dimensions of each part connected to the motor and elevator match. Here are the dimensions and fit tolerances of the positioning boss, and elevator groove of the motor.
Regularly check the connection of each part of the hydraulic elevator, and all connecting shafts must have split pins and be sufficient.
where.What are the installation precautions for elevators? The folding fence and cage of the elevator should be cleaned of the foundation surface, and the foundation bolts should be installed properly. If the construction elevator is installed on the floor,da tongFixed electric hydraulic lifting platform, a pad iron must be used below the screws to increase the force surface between the nuts and the floor to reduce the impact of the nuts on the floor; Insert steel plate shims of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite to ensure the verticality of each main pipe in both directions. After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and tighten the remaining anchor bolts; Install the buffer spring; Connect the other half of the fence to the front half with bolts; Adjust the verticality and tighten the anchor bolts as above, and release the brake on the motor inside the suspension cage. (For SC200/200 models, first install the suspension cage before installing the drive plate).
Before installing the elevator bearings, do not open the packaging too early. This can easily lead to premature bearing contamination, which can lead to premature bearing damage. Additionally, ensure that the installation environment is clean and do not bring iron filings, dust, and other objects into the bearings. Even small dust particles can cause premature bearing damage Prolonged use can also affect the running in between bearings, leading to a decrease in the lifespan of the elevator.
Talking about the daily maintenance and use of hydraulic lifting platform motors. Overloading is strictly prohibited, as overloading can increase the burden on the motor and in severe cases, cause the motor to burn out.
Every month, it should be ensured to add butter twice to the transmission position where the grease nipple is located. For areas where butter cannot be added, it is necessary to clear the oil circuit or replace the grease nipple until butter can be added. Otherwise, it is prohibited to use the equipment.
demand.The power unit adjustment, whether it is a scissor type lifting platform or a guide rail type lifting cargo elevator, is composed of the power unit and the oil cylinder. The power unit has four outlets during production, which can be adjusted to increase or decrease the hydraulic oil flow rate of the oil cylinder. We can adjust the motor speed or the electro-hydraulic proportional valve to adjust the hydraulic oil flow rate; What factors will affect the lifting speed of hydraulic elevators? The longer the hydraulic oil pipe, the longer the lifting time. Therefore, during installation, the length of the oil pipe should be minimized as much as possible within the allowable range of the design; On the basis of adjusting the power unit, the size of the oil pipeline can also be adjusted, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting requirements of different operation heights, and can be equipped with various table forms (such as ball, roller, turntable, tipping, telescoping), and with various ways (separate, linkage, prevention), it has the characteristics of stable and accurate lifting frequent starting, and large load capacity, Effectively solve various lifting and lowering difficulties in industrial enterprises making production operations easy.
When personnel enter the interior of the lifting platform for maintenance of outdoor elevators, they must hang the elevator to prevent sudden lowering of the platform and causing casualties.
da tong.How to install and use the bearings of the elevator? During the process of using the bearing device of the elevator, we cannot always ensure that the bearing device has the right orientation, which inevitably leads to some devices not being in place or bearing displacement. Once these problems occur in the device, it will cause the clearance between the bearings to become too small, and then make it impossible for the inner and outer rings of the bearings to be in the same rotation center. So it is necessary to use specialized tools when installing bearings, and in the future, it is also necessary to use a testing instrument to test the bearing installation, in order to ensure the success of the bearing installation.
The second is that the steel will have obvious thermal expansion effect at low temperature. Although this property of steel will be taken into account when designing and manufacturing hydraulic elevators, the environment is different after all. Under low conditions, the steel will have some unstable performance, toughness decline,da tongElectric fixed hydraulic lifting platform, etc. At this time, more attention should be paid to the maintenance of equipment to keep key parts to avoid dry grinding.
Remove and disassemble the lowering valve, blow the valve core clean with compressed air, and then reinstall it.
