Description

Technical Field

[0001] The utility model relates to an improvement of an elevator maintenance device, in particular to a portable control cabinet maintenance handle. Background Art

[0002] The control cabinet is the operation control equipment of the elevator, which is usually installed in the elevator shaft. The elevator needs to be inspected and maintained regularly. During the inspection, it is necessary to change the operation mode of the control cabinet to carry out the inspection work. During the inspection, separate manual control is required, so it is usually necessary to equip it with an inspection handle (controller). The conventional inspection handle is large in size and requires a large space in the control cabinet when it is stored. As the available space in the elevator shaft becomes smaller and smaller, the control cabinet is also shrinking in size, and the storage of the conventional inspection handle becomes a problem. Therefore, the inspection handle needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a portable control cabinet maintenance handle.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is as follows: the maintenance handle includes a bottom shell, a top shell, and a control switch. The bottom shell and the top shell are arranged in a mutual matching manner and form an installation space inside. The control switch includes up and down buttons, an emergency stop button, and an emergency electric switch, and is exposed and installed on the top shell. The bottom electrical part of the control switch is placed in the installation space. The bottom surface of the bottom shell is provided with a hanging hole, and the maintenance handle is placed on a vertical plane through the hanging hole. The maintenance handle is fixed with a matching structure, and the hanging hole is provided on the bottom shell, so it can be placed on various planes, making full use of the space in the control cabinet or the shaft, effectively improving space utilization, and is particularly suitable for elevators without a machine room. The maintenance handle can be conveniently controlled manually, is small in size, and is easy to control, thereby improving the efficiency of maintenance and emergency rescue.

[0005] Furthermore, the hanging hole is integrally formed on the bottom shell and comprises a recessed body and a narrowed hole. The recessed body forms a closed groove structure concavely on the bottom surface of the bottom shell, and the narrowed hole is formed at the top of the closed groove, flush with the bottom surface. The narrowed hole is located at the hook connection. By providing a hanging hole on the bottom shell, the maintenance handle can be mounted on various surfaces. The interior of the hanging hole is not connected to the mounting space, making the maintenance handle dustproof and waterproof, improving electrical safety.

[0006] Furthermore, the bottom surface of the bottom shell is formed into a flat surface, and a shock-absorbing anti-skid pad is provided on the bottom surface. The surface of the bottom shell is flat and smooth, suitable for various surfaces, and with the anti-skid pad, it is fixed and stable, and easy to take and put.

[0007] Furthermore, the up and down buttons are connected to the up and down control circuits of the control cabinet, the emergency stop button is connected to the stop switch of the control cabinet, and the emergency electric switch is connected to the safety circuit of the control cabinet. The up and down buttons mainly realize the single control of the up and down movement of the elevator car, the emergency stop button is used for emergency stop of the elevator, and the emergency electric switch is used to control the car to the correct landing when the safety circuit of the elevator has been triggered and the elevator brake has been applied, but the car is not stopped at the corresponding landing. When power is still supplied, the emergency electric switch is used to control the car to the correct landing through the emergency electric switch to facilitate the rescue of trapped people.

[0008] Furthermore, the bottom shell and top shell are both integrally injection-molded from fire-resistant plastic. A logo is provided on the top shell, and arc-shaped anti-touch ribs are provided on the side panels of the emergency stop button and emergency electric switch, with a working notch. Because both the emergency stop button and the emergency electric switch are dangerous when triggered, the anti-touch ribs are provided to ensure that the corresponding operation is carried out only after the hidden danger has been eliminated.

[0009] Compared with the existing technology, the utility model has the following advantages and effects: the design is a convenient control cabinet maintenance handle, which is mainly used in conjunction with a machine room-less control cabinet. It can be used at a certain distance away from the control cabinet, which is convenient for maintenance and emergency rescue of elevators, and improves the safety of elevators. In addition, the body is small in size and can be set according to the actual environment on site. The placement process is simple and effective. BRIEF DESCRIPTION OF THE DRAWINGS
