Seventeen greeThe safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s,Seventeen green ancient citySmall electric hydraulic elevator, with a size of 8 meters by 2 meters.
Seventeen green ancient city.Requirements for the operation platform of the construction lowering machine and the setting of the brake reset emergency stop switch: The shutdown device (emergency stop switch) should be able to stop or maintain the electric elevator (including the power driven door) in a non working state
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
.Monthly maintenance and inspection of hydraulic lifting platform rollers,Seventeen green ancient cityElectric elevator 10 meters, intermediate shafts and bearings, 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, 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 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 scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
From the perspective of the safety performance of the machinery itself,Seventeen green ancient citySmall electric winch elevator, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
In addition, when adding hydraulic oil, it is necessary to ensure the quality of the hydraulic oil, as some hydraulic oil manufacturers will choose hydraulic oil with poor quality. Hydraulic oil such as hydraulic lifting platforms not only cannot have any effect on folding arm elevators, but also affects the working efficiency of folding arm electric elevators due to deterioration issues.
The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
Inspection items.The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness strength, stability, etc., and the production should meet the design requirements.
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
original.As a material loading and unloading equipment recognized by customers in the lifting platform, the guide rail hydraulic lifting platform is superior in terms of product, civil engineering, and operating costs. The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load, can achieve multiple points, and can be controlled up and down floors to achieve safe use.
The magnetic directional valve returns to the fuel tank. To ensure stable landing 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 landing speed does not change due to heavy objects. It is adjusted by the saving valve
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Seventeen green ancient city.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, but safety should be maintained.
The pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
