Description

Technical Field

[0001] This utility model relates to the field of elevator testing technology, and in particular to a support device for elevator testing. Background Technology

[0002] An elevator is a transportation device that vertically transports people or goods. It is an electromechanical device that uses a car body running on rigid guide rails or steps running along a fixed route to lift or transport people or goods horizontally. It includes passenger elevators, freight elevators, escalators, moving walkways, etc.

[0003] Elevator inspection is a crucial step in ensuring safe elevator operation. It primarily includes checking basic information and documentation, machine room inspection, car inspection, and hoistway inspection. This involves verifying the traction machine's proper functioning, detecting any abnormal noises or vibrations, and ensuring the brakes operate reliably. Elevator inspection covers a wide range of aspects, from basic information to the performance of individual components and the overall system. Rigorous testing ensures the safe and reliable operation of elevators, protecting the lives and property of passengers.

[0004] In existing technical solutions, when inspecting the top components of an elevator car, the elevator car can be lowered to the door position, allowing operators to directly observe the upper part of the car for inspection through the open door. However, if components such as the door operator's motor, transmission device, or belt malfunction while the door is open, the elevator door may suddenly close. For example, a damaged door operator motor may cause the elevator door to lose control and close abruptly. A closed elevator door not only poses a safety hazard to the inspectors but also leaves no leverage point for opening the door, thus affecting the elevator inspection process.

[0005] Therefore, a support device for elevator testing is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution:

[0027] An elevator inspection support device includes a main board 1. A rotating shaft 2 is movably connected inside the main board 1. A handle 21 is fixedly connected to the front end of the rotating shaft 2, and a gear 22 is fixedly connected to the rear end of the rotating shaft 2. An opening / closing assembly 3 is provided inside the main board 1. The opening / closing assembly 3 includes a first sliding plate 31 and a second sliding plate 32 movably connected inside the main board 1. The second sliding plate 32 is located at the rear end of the first sliding plate 31. A rack 33 is fixedly connected to the ends of both the first sliding plate 31 and the second sliding plate 32 that are close to each other. A first locking plate is fixedly connected to the rear end of the first sliding plate 31. 34. The rear end of the second slide plate 32 is fixedly connected to a second locking plate 341. The upper and lower ends of the main board 1 are provided with first sliding grooves 11. The outside of the first locking plate 34 is fixedly connected to a first sliding rod 35. The outside of the second locking plate 341 is fixedly connected to a second sliding rod 351. The gear 22 and the rack 33 mesh with each other. The first slide plate 31 and the second slide plate 32 are both slidably attached to the inside of the main board 1. The first sliding rod 35 and the second sliding rod 351 both extend to the outside of the first sliding groove 11. The first sliding rod 35 and the second sliding rod 351 are both slidably attached to the inside of the first sliding groove 11.

[0028] By adopting the above technical solution, when inspecting the elevator, the elevator car is stopped at the elevator door. When the elevator door malfunctions and cannot be opened normally, the first card plate 34 and the second card plate 341 at the rear of the main board 1 are inserted into the gap between the elevator door and the door. Then, the operator rotates the handle 21. The rotation of the handle 21 causes the rotating shaft 2 and the gear 22 to rotate together. Then, the gear 22 causes the rack 33 to mesh with the first slide plate 31. The rack 33 inside the second slide plate 32 and the first slide plate 31 moves to the left and right ends respectively. The movement of the rack 33 and the first slide plate 31 causes the first card plate 34 and the second card plate 341 to move the elevator door. This increases the force application point on the closed elevator door through the opening and closing component 3 and performs separation work, thereby facilitating the support work for elevator door inspection and greatly improving the efficiency of elevator inspection.

[0029] Specifically, such as Figure 4As shown, support components 4 are provided around the outer perimeter of the motherboard 1. The support components 4 include a storage box 41 fixedly connected to the outside of the motherboard 1. A second sliding groove 411 is provided at the lower outer end of the motherboard 1. A cavity 412 is provided inside the storage box 41. A top post 421 is movably connected inside the cavity 412. A slot 422 is provided on the outside of the top post 421. A spring 42 is fixedly connected between the top post 421 and the cavity 412. A spring piece 43 is fixedly connected to the inner wall of the cavity 412. The top post 421 slides against the inside of the cavity 412. The elastic force of the spring 42 is greater than the sum of the weights of the top post 421. The first sliding groove 11 and the second sliding groove 411 are connected through each other. The spring piece 43 penetrates into the inside of the second sliding groove 411.

[0030] By adopting the above technical solution, when the elevator door is separated by the opening and closing component 3, as the first card plate 34 and the second card plate 341 move, the first slide rod 35 and the second slide rod 351 move together inside the first slide groove 11. The first slide rod 35 and the second slide rod 351 move continuously and touch the spring piece 43 on the inner wall of the cavity 412 after entering the second slide groove 411. After the spring piece 43 leaves the slot 422 inside the top column 421, the top column 421 inside the cavity 412 is pushed out of the storage box 41 by the spring 42 to support the elevator door. This prevents the elevator door from suddenly closing during the inspection process, which would affect the elevator inspection and thus improve the safety of the elevator inspection work.

[0031] Working principle: By inserting the first card plate 34 and the second card plate 341 at the rear of the main board 1 into the gap of the elevator door, the operator rotates the handle 21. The rotation of the handle 21 causes the rotating shaft 2 and the gear 22 to rotate together. Then, the gear 22 causes the rack 33 to mesh with the first slide plate 31. The rack 33 inside the second slide plate 32 and the first slide plate 31 moves to the left and right ends respectively. The movement of the rack 33 and the first slide plate 31 causes the first card plate 34 and the second card plate 341 to move the elevator door body. For the closed elevator door, the opening and closing component 3 increases the force application point of the closed elevator door and performs separation work, thereby facilitating the support work of elevator door detection and greatly improving the work efficiency of elevator detection.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
