Description

Technical Field

[0001] The utility model relates to the technical field of elevator detection equipment, in particular to an elevator operation fault monitoring device. Background Art

[0002] The elevator braking capacity tester is mainly used to test whether the performance and function of the elevator braking system are qualified. It consists of a detection handheld terminal and a front-end wheel. During the test, the front-end wheel is placed near the elevator wire rope and rotates with the movement of the wire rope. When the elevator reaches the set travel or rated elevator speed, the tester will send an elevator braking signal and start measuring the travel distance of the wire rope. After the elevator stops, the device will automatically display and record the test results to help users determine whether the elevator's braking capacity meets the requirements. Through regular testing, problems with the elevator braking system can be discovered in time, thereby avoiding potential safety risks. At the same time, the tester can also provide data support for the maintenance and management of the elevator, helping relevant personnel to better understand the operating status of the elevator and formulate a more reasonable maintenance plan.

[0003] The main function of the wire rope is to connect the elevator car and counterweight, and bear the weight and pressure of the elevator during operation and parking. The elevator motor realizes the lifting and lowering movement of the elevator through the cooperation of the drive wheel and the wire rope.

[0004] The patent with announcement number CN217384542U currently discloses an elevator braking capacity tester, including an elevator braking capacity tester, a clamping wheel is fixedly installed on the front of the elevator braking capacity tester, a guide frame is slidably installed on the lower part of the elevator braking capacity tester, and the lower part of the guide frame is rotatably connected to a fixed plate, the clamping wheel includes a rotating wheel, a fixed shaft, a first return spring and a swivel seat, the rotating wheel is rotatably connected to the inner end of one side of the swivel seat, and the swivel seat is rotatably installed on the rear of the fixed shaft.

[0005] However, the above technical solution still has the following problems:

[0006] The steel wire rope of an elevator is usually installed above the elevator motor and connected to the elevator car and counterweight to achieve the lifting function of the elevator. It is not easy for workers to touch the steel wire rope with a handheld elevator braking capacity tester. If the tester cannot easily touch the steel wire rope, it will become more difficult to detect problems such as wear, breakage, and looseness of the steel wire rope. This may cause some potential safety hazards to be ignored and increase the risk of elevator failure. If workers need to take unsafe operations or positions in order to contact the steel wire rope, such as climbing to a high place or using unstable supports, the risk of work-related injuries may increase. For situations where the steel wire rope needs to be maintained or adjusted regularly, if the tester cannot easily touch the steel wire rope, it will increase the difficulty and time cost of maintenance work. Utility Model Content

[0007] In view of the deficiencies of the prior art, the utility model provides an elevator operation fault monitoring device to at least solve one of the problems raised by the background technology, such as: improving the efficiency and accuracy of the detection work of the elevator braking capacity detector.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator operation fault monitoring device, including a body, a support assembly is installed at one end of the body, the support assembly and the body can be separated, the support assembly is composed of a plurality of hollow tubes connected by end-to-end threads, a storage box is installed on one side of the body, and the hollow tubes can be stored in the storage box.

[0009] Furthermore, a threaded head is arranged at one end of the hollow tube, and an internal threaded end is arranged on the inner wall of the other end, the internal threaded end matches the threaded head, and a threaded groove matching the threaded head is arranged at the bottom of the body.

[0010] Furthermore, the thread directions of the thread head, the internal thread end and the thread groove are consistent.

[0011] Furthermore, an anti-slip pad is provided on the outer side of the hollow tube at the rear of the support assembly.

[0012] Furthermore, a slide groove is provided at the bottom of the body, an inner wall of one side of the slide groove is connected to the outside, and a sliding block slidably connected to the slide groove is fixedly connected to the top of the storage box.

[0013] Furthermore, the cross sections of the slide groove and the slider are both T-shaped.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model installs a support rod with adjustable length on the elevator braking capacity tester, so that workers can hold the support rod to test the wire rope that is difficult to approach. The adjustable length function of the support rod allows workers to adjust the height and position of the tester according to actual needs, so that it is easier to approach and detect those parts of the wire rope that are originally difficult to reach. This helps to ensure a comprehensive test of the elevator braking capacity and avoid missing any key areas. By using the support rod, workers can perform testing work while maintaining a safe distance, avoiding the risk of directly climbing or contacting the elevator equipment. This helps to reduce the occurrence of work-related accidents and protect the lives of workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, an elevator operation fault monitoring device includes a body 1, a support assembly 2 is installed at one end of the body 1, the support assembly 2 and the body 1 can be separated, the support assembly 2 is composed of a plurality of hollow tubes 3 connected by end-to-end threads, a storage box 4 is installed on one side of the body 1, and the hollow tubes 3 can be received in the storage box 4.

[0024] like Figure 1 As shown, an elevator operation fault monitoring device in the utility model is similar in structure to the existing elevator braking capacity detector, such as the elevator braking capacity detector disclosed in the patent with announcement number CN217384542U. The main improvement of the utility model is to improve the safety of workers, reduce the occurrence of work-related accidents, and protect the life safety of workers. Figures 1 to 5 As shown, when an elevator operation fault monitoring device in the utility model is in use, the support component 2 and the body 1 are detachable, so that workers can choose whether to use the support component 2 according to actual needs. When it is necessary to detect a wire rope that is difficult to approach, the worker can hold the support component 2 and move the wheel of the body 1 close to the wire rope for operation, which improves the convenience of detection. The support component 2 is composed of a plurality of hollow tubes 3 connected by end-to-end threads, so that the length of the support component 2 can be adjusted as needed. By increasing or decreasing the number of hollow tubes 3, workers can easily adapt to wire rope detection tasks at different heights or positions. The hollow tubes 3 reduce the weight of the entire support component 2 and also make it have a certain bending resistance, which can resist external forces to a certain extent and maintain stability. When the support component 2 is not in use, workers can disassemble the hollow tubes 3 one by one and put them into the storage box 4 for easy carrying and transportation.

[0025] like Figures 1 to 3As shown, a thread head 301 is provided at one end of the hollow tube 3, and an internal thread end 302 is provided on the inner wall of the other end. The internal thread end 302 matches the thread head 301, and a thread groove 101 matching the thread head 301 is provided at the bottom of the body 1.

[0026] Specifically, through this arrangement, a threaded head 301 is provided at one end of the hollow tube 3, and an internal threaded end 302 is provided on the inner wall of the other end, so that each hollow tube 3 can be tightly connected with the adjacent hollow tube 3 through threads. The matching of the threaded head 301 and the internal threaded end 302 ensures the stability and sealing of the connection, and prevents the detection result from being affected by looseness or misalignment during the detection process. The threaded groove 101 opened at the bottom of the body 1 matches the threaded head 301 of the hollow tube 3, so that the support component 2 can be firmly installed on the body 1 to form a stable working platform. At the same time, this connection method also facilitates the separation of the support component 2 from the body 1. When the support component 2 is not needed, it can be easily disassembled for easy carrying and storage.

[0027] like Figures 1 to 3 As shown, the thread directions of the thread head 301 , the internal thread end 302 and the thread groove 101 are consistent.

[0028] Specifically, through this arrangement, when the hollow tubes 3 are connected or the hollow tubes 3 and the body 1 are connected, the thread direction is consistent, and workers only need to rotate in the same direction to achieve a tight connection, which improves the efficiency of the connection and reduces the risk of installation difficulties or damage to the thread due to incorrect direction. The consistent thread direction ensures that the force between the various components is evenly distributed during the connection process, thereby improving the stability of the entire support assembly 2.

[0029] like Figure 2 As shown, an anti-slip pad 5 is provided on the outer side of the hollow tube 3 at the rear of the support assembly 2 .

[0030] Specifically, the anti-slip pad 5 is provided to increase the friction between the hollow tube 3 and the contact surface, so that workers can hold the hollow tube 3 more firmly when holding the support assembly 2 for inspection, preventing accidental falling off or damage due to hand slippage or instability.

[0031] like Figure 4 As shown, a slide groove 102 is provided at the bottom of the body 1 , an inner wall of one side of the slide groove 102 is connected to the outside, and a slider 6 slidably connected to the slide groove 102 is fixedly connected to the top of the storage box 4 .

[0032] Specifically, by setting the sliding connection design between the slider 6 and the slide groove 102 , the storage box 4 can be installed on the body 1 and fixed by sliding. When the storage box 4 needs to be removed, the slider 6 is slid out of the slide groove 102 .

[0033] like Figures 4 to 5 As shown, the cross sections of the slide groove 102 and the slider 6 are both T-shaped.

[0034] Specifically, the T-shaped cross-section design enables a larger contact area between the slide groove 102 and the slider 6, thereby providing higher stability. This design can effectively prevent the slider 6 from shaking or falling off in the slide groove 102, thereby ensuring that the connection between the storage box 4 and the body 1 is firm and reliable.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
