Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, and in particular to an elevator shaft cable detection device. Background Technology

[0002] With the acceleration of urbanization, elevators have become an indispensable vertical transportation tool in modern buildings. Elevator shaft cables are a crucial component for the safe operation of elevators, and their condition directly affects the normal operation of the elevator and the safety of passengers. Traditional methods for inspecting elevator shaft cables mainly rely on manual visual inspection, which is not only inefficient but also poses significant safety hazards. Manual inspection requires personnel to enter the shaft, exposing them to risks such as falls from heights and electric shocks. Furthermore, due to the complex environment and dense cable distribution within the shaft, manual visual inspection is insufficient for a comprehensive and detailed examination, easily overlooking potential damage or wear.

[0003] While some automated testing equipment exists on the market, most of these devices are complex in structure and bulky, making them unsuitable for the confined environment of elevator shafts. Furthermore, existing automated testing equipment has poor adaptability to elevator shaft cables, especially flat cables, failing to achieve proper clamping and stable movement, resulting in unstable testing processes and inaccurate results.

[0004] In view of the shortcomings of the existing technology, this application proposes a detection device specifically for elevator shaft cables, which aims to solve the problems of low efficiency and high safety risks of traditional manual detection, as well as the poor adaptability and limited functionality of existing automated detection equipment. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an elevator shaft cable detection device.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An elevator shaft cable detection device, comprising: The housing has an open side and openings at the top and bottom for the elevator shaft cables to pass through. The traveling device, installed inside the housing, can clamp the elevator shaft cable and travel along the elevator shaft cable; The detection device consists of two devices installed inside the housing, with the two detection devices located on either side of the traveling device; the detection devices take pictures of the elevator shaft cable as they travel along the elevator shaft cable.

[0007] Preferably, the walking device includes: The mounting brackets consist of two corresponding cross-shaped brackets, with the center of each bracket hinged to the housing. There are two drive wheels, each rotatably connected to one end of a mounting bracket. There are two driven wheels, each rotatably connected to the other end of one of the two mounting brackets; The first motor consists of two motors, which are mounted on two mounting brackets and connected to the two drive wheels respectively. The drive mechanism, installed inside the housing, drives two mounting brackets to deflect, causing the two drive wheels and two driven wheels to move closer or further apart, thereby clamping or releasing the elevator shaft cables.

[0008] Preferably, the drive mechanism includes: The slider is slidably connected to the housing. There are two connecting rods. One end of each connecting rod is hinged to the corresponding slider, and the other end of each connecting rod is hinged to the corresponding mounting bracket. A telescopic device, installed on one side of the slider, is used to drive the slider to move; the telescopic device can be a telescopic cylinder or a lead screw and nut transmission mechanism.

[0009] Preferably, the lead screw and nut transmission mechanism includes: The guide rods are two spaced apart, and the two guide rods move through the slider. The first connecting plate is installed at one end of the two guide rods; The second connecting plate is installed at the other end of the two guide rods; Two springs are provided, and the two springs are respectively sleeved on the rods of the two guide rods located between the second connecting plate and the slider; The lead screw is threadedly connected to the second connecting plate, and the lead screw moves through the slider and the first connecting plate. The second motor is mounted on the housing, and its output is connected to the lead screw drive.

[0010] Preferably, the outer surfaces of both the drive wheel and the driven wheel are provided with annular grooves that correspond to and are adapted to the width of the elevator shaft cable.

[0011] Preferably, the detection device includes: Mounting base, which is securely connected to the housing; The camera is mounted on a mounting base.

[0012] Preferably, a fill light is installed on the mounting base at the position corresponding to the camera.

[0013] Preferably, a handle is installed on one side of the housing.

[0014] By adopting the technical solution described above, this utility model has the following beneficial effects: (1) The ingenious structure of this practical walking device enables it to clamp elevator shaft cables and move along them. By controlling the deflection of the two mounting brackets, the drive wheel and driven wheel can clamp or release the cables synchronously. With the drive of the first motor, the device can be pulled up or down along the elevator shaft cables. This design not only improves the mobility of the device, but also enables the detection of the elevator shaft cables throughout the entire process, avoiding the blind spots that exist in manual detection, and greatly improving the detection efficiency and comprehensiveness.

[0015] (2) The drive mechanism inside the housing of this utility model includes a slider, a connecting rod, and a telescopic device, which can accurately control the clamping and loosening of the cable by the drive wheel and the driven wheel. It is easy to operate and highly reliable.

[0016] (3) The detection device of this utility model is located on both sides of the walking device, and can take pictures of both sides of the elevator shaft cable for detection. Compared with the traditional manual visual inspection method, it not only improves the detection efficiency, but also avoids the risks of manual inspection and protects the personal safety of the inspection personnel. Moreover, the captured images can be archived as the basis for detection, which is convenient for subsequent comparison with previous images and timely detection of changes and potential problems in the cable.

[0017] (4) This utility model further improves the screw nut transmission mechanism. By setting up a guide rod, a first connecting plate, a second connecting plate and springs, the drive wheel or driven wheel can expand to overcome obstacles such as cable ties on the cable when the device encounters them. After overcoming the obstacles, the clamping state is quickly restored under the action of the spring rebound force, ensuring the continuity and stability of the detection operation and effectively solving the problem of detection interruption caused by obstacles.

Detailed Implementation

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Example 1

[0023] Combined with appendix Figures 1-5 An elevator shaft cable detection device includes a housing 1, a traveling device 2, and a detection device 3. The housing 1 is designed with one side open, and openings at both the top and bottom for elevator shaft cables to pass through. Since existing elevator shaft cables are typically flat, the openings on the housing 1 are elongated to better accommodate the cables.

[0024] A traveling device 2 is installed inside the housing 1. This traveling device 2 has the function of clamping the elevator shaft cable and moving along the elevator shaft cable. (See attached image) Figure 2As shown, the traveling device 2 consists of a mounting frame 2-1, a drive wheel 2-2, and a driven wheel 2-3. The mounting frames 2-1 are arranged in a corresponding, cross-shaped configuration, with two frames hinged at their centers to corresponding parts of the housing 1. Drive wheels 2-2 are rotatably connected to one end of each mounting frame 2-1, while driven wheels 2-3 are rotatably connected to their other ends. By controlling the rotation of the two mounting frames 2-1 around their center positions, the two drive wheels 2-2 can be brought closer together, thus clamping the elevator shaft cable. Simultaneously, the two driven wheels 2-3 will also clamp the elevator shaft cable. Conversely, if the two drive wheels 2-2 are moved away from each other, the elevator shaft cable can be released, and the two driven wheels 2-3 will similarly release simultaneously.

[0025] Two first motors 2-4 are mounted on each of the two mounting brackets 2-1, and each of the two first motors 2-4 is connected to a corresponding drive wheel 2-2. When the drive wheel 2-2 successfully clamps the elevator shaft cable, the synchronous drive of the two first motors 2-4 causes the two drive wheels 2-2 to rotate, thereby pulling the entire device along the elevator shaft cable. Furthermore, by controlling the forward and reverse rotation of the first motors 2-4, the upward or downward movement of the entire device along the elevator shaft cable can be controlled.

[0026] In order to achieve the purpose of controlling the drive wheel 2-2 to clamp or release the elevator shaft cable, a drive mechanism is provided inside the housing 1. The drive mechanism is used to drive the two mounting brackets 2-1 to deflect, thereby causing the two drive wheels 2-2 and the two driven wheels 2-3 to move closer or further apart, so as to achieve the function of clamping or releasing the elevator shaft cable.

[0027] Specifically, the drive mechanism includes a slider 2-5, a connecting rod 2-6, and a telescopic device. The slider 2-5 is slidably connected to the housing 1, and a groove is provided on the housing 1 corresponding to the position of the slider 2-5, allowing the slider 2-5 to slide linearly along the groove of the housing 1, as shown in the attached figure. Figure 3 As shown. Two connecting rods 2-6 are hinged to the top of the slider 2-5, and the other ends of these two connecting rods 2-6 are respectively hinged to corresponding parts of the two mounting brackets 2-1. When the slider 2-5 slides linearly along the groove of the housing 1, it will drive the two connecting rods 2-6 to move, which in turn drives the two mounting brackets 2-1 to move. (See attached diagram) Figure 2 and 4 As shown, when slider 2-5 moves away from driven wheel 2-3, the two drive wheels 2-2 and the two driven wheels 2-3 will clamp the elevator shaft cable accordingly; conversely, when slider 2-5 moves closer to driven wheel 2-3, the two drive wheels 2-2 and the two driven wheels 2-3 will release the elevator shaft cable accordingly.

[0028] The telescopic device is installed on one side of the slider 2-5. Its main function is to drive the slider 2-5 to move, thereby controlling the clamping or loosening of the elevator shaft cable by the drive wheel 2-2 and the driven wheel 2-3. Depending on the actual needs, the telescopic device can be a telescopic cylinder or a lead screw and nut transmission mechanism. Both telescopic cylinders and lead screw and nut transmission mechanisms are common products on the market and both have linear drive functionality.

[0029] There are two detection devices 3, both installed inside the housing 1, and located on either side of the traveling device 2. During the movement along the elevator shaft cable, the detection devices 3 photograph the cable from both sides to determine if there is any damage or wear. The captured images are archived as evidence for later comparison with previous images or as a reference for subsequent inspections. Compared to traditional manual visual inspection, this method significantly improves inspection efficiency and ensures the safety of inspection personnel. Example 2

[0030] During actual testing, it was found that elevator shaft cables are often bundled with other signal transmission cables using cable ties. However, the presence of these cable ties can easily cause the drive wheel 2-2 or driven wheel 2-3 to jam unexpectedly, leading to an interruption of the testing process. This embodiment addresses this technical challenge with further improvements and optimizations.

[0031] Combined with appendix Figure 2 , 4 Furthermore, this utility model relates to an elevator shaft cable detection device. Compared with Embodiment 1, the difference lies in the improvement of the lead screw and nut transmission mechanism based on Embodiment 1. The improved lead screw and nut transmission mechanism includes guide rods 2-7, a first connecting plate 2-8, and a second connecting plate 2-9. There are two guide rods 2-7, spaced apart, which movably pass through the slider 2-5, meaning the guide rods 2-7 can move relative to the slider 2-5. The first connecting plate 2-8 is installed at one end of the two guide rods 2-7, and the second connecting plate 2-9 is installed at the other end. The first connecting plate 2-8, the second connecting plate 2-9, and the two guide rods 2-7 together form a frame structure, allowing the slider 2-5 to move between the first connecting plate 2-8 and the second connecting plate 2-9.

[0032] Springs 2-10 are fitted onto the two guide rods 2-7 located between the second connecting plate 2-9 and the slider 2-5. Under normal conditions, the springs 2-10 press against the slider 2-5, keeping the slider 2-5 in contact with the first connecting plate 2-8.

[0033] The second connecting plate 2-9 is threadedly connected to the lead screw 2-11, and the lead screw 2-11 moves through the slider 2-5 and the first connecting plate 2-8. A second motor 2-12 is installed on the housing 1, and the output end of the second motor 2-12 is connected to the lead screw 2-11. The second motor 2-12 drives the lead screw 2-11, which in turn drives the second connecting plate 2-9. The second connecting plate 2-9, with the help of the spring 2-10, pushes the slider 2-5 away from the driven wheel 2-3, thereby achieving the action of the drive wheel 2-2 and the driven wheel 2-3 clamping the elevator shaft cable. Conversely, when the second motor 2-12 rotates in the opposite direction, the second connecting plate 2-9 drives the first connecting plate 2-8 to move through the guide rod 2-7. The first connecting plate 2-8 pulls the slider 2-5 closer to the driven wheel 2-3, thereby causing the drive wheel 2-2 and the driven wheel 2-3 to release the elevator shaft cable.

[0034] When either the drive wheel 2-2 or the driven wheel 2-3 encounters an obstacle such as a cable tie on the elevator shaft cable, the drive wheel 2-2 or the driven wheel 2-3 can expand. At this time, the mounting bracket 2-1 pulls the slider 2-5 through the connecting rod 2-6. The slider 2-5 compresses the spring 2-10 and moves, thus achieving the purpose of overcoming the obstacle. After overcoming the obstacle, under the rebound force of the spring 2-10, the slider 2-5 returns to its initial position, and the drive wheel 2-2 or the driven wheel 2-3 can quickly clamp the elevator shaft cable again, thereby ensuring the smooth progress of the inspection operation. Example 3

[0035] Combined with appendix Figure 1 and 6 This utility model relates to an elevator shaft cable detection device. Based on embodiment one or two, the detection device 3 has been further refined. The detection device 3 includes a mounting base 3-1 and a camera 3-2. The mounting base 3-1 is securely connected to the housing 1, and the camera 3-2 is mounted on the mounting base 3-1. By setting two cameras 3-2, the front and back sides of the flattened elevator shaft cable can be detected simultaneously, greatly improving detection efficiency.

[0036] Furthermore, a supplementary light 3-3 is installed on the mounting base 3-1 corresponding to the position of the camera 3-2. This design effectively ensures that the camera 3-2 can acquire images normally, avoiding poor image quality due to weak light in the elevator shaft, which would affect the subsequent judgment results. Example 4

[0037] Combined with appendix Figures 1-3This utility model relates to an elevator shaft cable inspection device. Based on any one of the embodiments in Examples 1 to 3, a handle 4 is installed on one side of the housing 1. The handle 4 is designed to facilitate the inspection personnel to carry the device. At the same time, during the inspection operation, it is convenient for the inspection personnel to place the entire device on the elevator shaft cable, or to remove the device from the elevator shaft cable after the inspection is completed. Its structure is simple and easy to use. Example 4

[0038] Combined with appendix Figures 1-3 An elevator shaft cable inspection device, based on any of the embodiments one to three, has a handle 4 installed on one side of the housing 1. This facilitates portability. Simultaneously, it allows inspectors to easily place the entire device on the elevator shaft cable or remove it from the cable after inspection. The device has a simple structure and is easy to use.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
