Description

Technical Field

[0001] The utility model relates to the technical field of maintenance platforms, in particular to a machine room-less passenger elevator maintenance platform. Background Art

[0002] In recent years, the development of the passenger elevator industry has changed from the past machine-room passenger elevator to the machine-roomless passenger elevator. The machine-roomless passenger elevator adopts variable frequency speed regulation microcomputer control, which is very different from the previous vertical passenger elevator in structure. In order to save space, the control cabinet, main engine, speed limiter and other equipment that were previously installed in the machine room above the shaft are installed in the shaft instead of the machine room, and the dedicated machine room is cancelled. It effectively improves the utilization rate of the building area and reduces the construction cost. At the same time, it saves materials and reduces the top floor height. Since the machine-roomless passenger elevator does not have a machine room, its control system has higher flexibility, convenience and reliability than ordinary passenger elevators. However, in most machine-roomless passenger elevators, the traction machine system is installed on the top of the shaft. To inspect and repair the traction machine and other components, the maintenance personnel need to stand on the top of the car. When the top floor is too high, because the height of the car top is limited, the maintenance personnel standing on the passenger elevator car top still cannot perform maintenance on the traction machine and other components, which makes the inspection and maintenance process difficult. Utility Model Content

[0003] In order to overcome the problem that most machine roomless passenger elevators have traction machine systems installed on the top of the shaft, during the maintenance process, the maintenance personnel cannot perform maintenance on the traction machine system even when standing on the top of the passenger elevator car due to insufficient height, which slows down the maintenance process.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional machine roomless passenger elevator, the traction machine system is installed on the top of the shaft. To inspect and repair the traction machine and other components, the maintenance personnel need to stand on the top of the car. When the top floor is too high, the maintenance personnel cannot perform maintenance on the traction machine and other components even if they stand on the top of the passenger elevator car because the height of the car top is limited, which makes the maintenance and repair process difficult. This device makes the maintenance personnel rise and fall with the maintenance platform by lifting the maintenance platform, which is convenient for the maintenance personnel to inspect and repair the traction machine and speed up the maintenance process.

[0014] 2. When the platform is lifted, the electric telescopic rod is extended and retracted to drive the power rod to move. The power rod moves in the slide slot, driving the combination of multiple lifting rods and multiple connecting rods to deform, so that the workbench can be lifted and lowered, and the maintenance personnel can be raised to perform maintenance on the traction machine. This can solve the problem that in most machine roomless passenger elevators, since the traction machine system is installed on the top of the hoistway, the maintenance personnel cannot perform maintenance on the traction machine system even when standing on the top of the passenger elevator car due to insufficient height, which slows down the maintenance process. This increases the practical value of the device.

[0015] 3. During maintenance work, the maintenance personnel climb onto the top of the car and push the safety cover with their hands, driving the connecting block to rotate around the rotating rod. Under the limit of the rotating pin, the safety cover rises and the maintenance personnel enter the workbench through the entrance and exit. The guardrail frame can be used as a handrail to facilitate the maintenance personnel's work during maintenance work. The guardrail support reinforces the guardrail frame. During the maintenance process, the fixed seat and the fixed frame are connected to the car to bear the weight of the device and personnel, thereby improving the safety of the device.
