El Prague.Electric lifting machinery, as an important product of social development in China, has a high social status and has now become an irreplaceable operational tool in our mainstream goods. The hydraulic pump station is the heart position of electric lifting machinery, which greatly tests the professionalism and attention of operators. It is our common responsibility to inspect it and ensure the daily use of machinery. Let's take a look at a few common sense issues: the manufacturer of electric elevators is to ensure the correctness of the power connection, and there should be no misconnection or leakage; Pay attention to cleaning work in daily life and do not allow stains to corrode it; When standing still, regular maintenance should be carried out to prevent the impact of rain and snow weather; Overloading is the first thing that operators must comply with; Iron Law&# quo;; The adjustment of the solenoid valve cannot be done arbitrarily and must be checked and certified by a professional organization; Especially when conducting outdoor operations under high temperatures, as long as these problems are not very serious, we don't have to worry too much. However, when there is a problem with the hydraulic boarding bridge, only a timely solution is the correct response. Below is an introduction to some common faults of the hydraulic boarding bridge and specific solutions: the hydraulic boarding bridge must be repaired while hanging and supporting the working platform of the lifting platform to avoid sudden descent of the lifting platform, causing unnecessary casualties; 2. Do not adjust the overflow valve arbitrarily. Because every component in the hydraulic system operates at a specified pressure, it may cause abnormal operation of the hydraulic system, causing unnecessary damage to people, machines, and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
.The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.
Monthly maintenance and inspection of hydraulic lifting platform rollers, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process oil cylinder pin shafts and bearings intermediate shafts and bearings, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Stage equipment safety door. To prevent personnel from extending their heads hands, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
When using lifting equipment, the workbench should be kept in a horizontal state.
During normal operation,El PragueFully self-propelled electric elevator, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
technological innovation.The use of standard section connecting bolts should comply with the user manual and specification requirements.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, and a toe board at least 150mm above the ground.
consumption.The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters,El PraguePortable electric elevator, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
Equal effect.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
El Prague.The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
