WehrovoSmall electric elevatorHow to carry out special inspection work

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.

During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.

Wehrovo.8m； When the lifting speed is greater than 0.8m/s, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=8+0.1V2, where L is the upper safety distance; V: Increase speed

Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.

.During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.

Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement

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, 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 foundation base or embedded parts should be fully embedded in the concrete foundation plate.

The occurrence of.

Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.

Quality inspection report.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).

Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent

The L distance depends on the selected wall mount model.

knowledge.When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.

Before use,WehrovoElectric elevator, we should observe whether there is any damage to the electric elevator. We can conduct a no-load test to raise and lower it. If there are any damaged parts, they should be replaced in a timely manner to prevent major accidents.

Stage equipment safety door. To prevent personnel from extending their heads hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, 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, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.

Wehrovo.Work is essential,WehrovoMultifunctional electric elevator, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs etc.

The setting of the cable guide frame should comply with the user manual and regulatory requirements.

The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.
