Description

Technical Field

[0001] This utility model relates to the field of elevator car climbing technology, and more specifically, it relates to an elevator car climbing device. Background Technology

[0002] The elevator car is one of the main components of an elevator and is an enclosed space where passengers or goods move up and down. To ensure the normal operation of the elevator car and the safety of passengers, regular maintenance and upkeep are necessary. This includes checking the elevator's operating status, cleaning the interior of the car, and replacing worn parts. When an elevator malfunctions and needs repair, firefighters usually climb a ladder to the top of the car to troubleshoot the parts.

[0003] However, traditional ladders are mostly fixed, integrated structures. Since the access panels of elevator cars are small, if there is a large discrepancy between the height of the ladder and the internal height of the elevator car, it will be difficult to set up and will affect the efficiency of maintenance.

[0004] Furthermore, placing the ladder directly inside the elevator car is not stable and can easily cause it to tip over during maintenance, affecting safety. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides an elevator car climbing device to solve the problem mentioned in the background art that traditional climbing ladders are mostly fixed integrated structures. Since the inspection port of the elevator car is small, if there is a large deviation between the height of the climbing ladder and the internal height of the elevator car, there will be technical problems that make it difficult to install.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an elevator car climbing device, comprising a first ladder frame, guide grooves on both sides of the inner wall of the first ladder frame, guide blocks slidably disposed inside the guide grooves, a second ladder frame fixedly disposed between the two guide blocks, climbing stools fixedly disposed inside both the first and second ladder frames, adjustment holes on both sides of the second ladder frame, multiple adjustment holes arranged linearly, threaded holes on both sides of the first ladder frame at one end, first screws disposed inside the threaded holes and adjustment holes, and an overlapping device at the upper end of the second ladder frame, the overlapping device comprising an mounting block.

[0009] The present invention is further configured such that an overlapping plate is hinged inside the mounting block, and fixing blocks are provided on both sides of the overlapping plate on the outer wall of the mounting block. Each fixing block is provided with a positioning hole, and a corresponding connecting hole is provided on the outer wall of the overlapping plate. A second screw is provided inside the positioning hole and the connecting hole to facilitate the adjustment of the height of the second ladder.

[0010] The present invention is further provided with a screwing block fixed at one end of both the first screw and the second screw, so as to facilitate the disassembly and assembly of the first screw and the second screw.

[0011] The present invention is further provided with connecting rings fixed on the outer wall of the first ladder frame on both sides, and each connecting ring is provided with a self-locking hook inside. A shoulder strap is fixed in the middle of the self-locking hook to facilitate carrying the device.

[0012] The present invention is further provided with a soft pad fixed in the middle of the shoulder strap to facilitate protection of the wearer's shoulders.

[0013] The present invention is further provided with a grounding plate fixed on the lower end surface of the first ladder frame to facilitate support of the bottom of the device.

[0014] The present invention is further configured such that both the guide groove and the guide block are T-shaped structures, which facilitates the guidance of the second ladder frame.

[0015] The present invention is further provided with an anti-slip pad fixed at the bottom of the grounding plate, which facilitates increasing the friction between the grounding plate and the elevator car.
