During the guiding process of the guide wheel 1, the limiting part 3 is used to limit and fix the connecting part 2.

[0030] In the above technical solution, the wire rope detection device body 100 is a device that can detect whether the wire rope has problems such as damage and aging. When in use, it is used to be sleeved on the outside of the wire rope S to be tested. The staff moves the wire rope detection device body 100 along the length direction of the wire rope S to be tested, so as to detect the wire rope S to be tested. The present application does not limit the specific structure of the wire rope detection device body 100, as long as it can be sleeved on the outside of the wire rope S to be tested to detect the wire rope S to be tested; nor does it limit the specific number of the multiple guide wheels 1, which can be 2, 3, 4, etc. In some embodiments, in order to save manufacturing costs, the preferred number of guide wheels 1 is 2. The present application also does not limit the specific structure of the connecting part 2. For example, the connecting part 2 can be a rod body, a plate body, etc., as long as it can be connected to the guide wheel 1 so that the guide wheel 1 can roll and be hinged with the wire rope detection device body 100. For example, With the vertical direction being perpendicular to the ground, when the steel wire rope S to be tested is vertically arranged, the steel wire rope detection device body 100 is vertically sleeved on the outside of the steel wire rope S to be tested, and the two guide wheel assemblies 200 are respectively installed at the upper and lower ends of the steel wire rope detection device body 100, and each of the connecting parts 2 rotates with the steel wire rope detection device body 100 as a reference plane, so that the guide wheel 1 can move toward or away from the steel wire rope S to be tested, so as to adjust the distance between the multiple guide wheels 1. When adjusted to the required position, the limiting part 3 limits the connecting part 2, that is, limits the guide wheel 1. The present application does not limit the specific structure of the limiting part 3, nor does it limit the specific connection method between the limiting part 3 and the main body 100 of the wire rope detection device, as long as it can limit the connecting part 2.

In other embodiments, the limiting part 3 can be a screw, which fixes the connecting part 2 on the main body 100 of the wire rope detection device. When the connecting part 2 needs to be moved, the screw can be removed. In some embodiments, in order not to affect the sliding of the guide wheel 1, there is a gap of 1 mm between each guide wheel 1 and the wire rope S to be tested.

[0031] Each guide wheel 1 of the utility model is hinged to the wire rope detection device body 100 through the connecting part 2, that is, the position between the multiple guide wheels 1 can be adjusted, so that the multiple guide wheels 1 can be clamped on the outside of the wire ropes with different diameters. After adjusting the distance between the multiple guide wheels 1, each guide wheel 1 is limited and fixed by the limiting part 3, so that the guide wheel 1 can be clamped on the outside of the wire rope S to be tested during the guiding process, and can move along the length direction of the wire rope S to be tested under the action of external force. The wire rope detection device 1000 of the utility model can be applicable to wire ropes of different diameters and has a wide range of applications.

[0032] Exemplarily, the connecting portion 2 includes a base 21 and a bracket 22; the bracket 22 includes two ends that are arranged opposite to each other, one of which is connected to the corresponding guide wheel 1; the base 21 is installed on the wire rope detection device body 100, and the base 21 is hinged to the other end of the bracket 22. The present application does not limit the specific hinge structure between the base 21 and the bracket 22. For example, it can be that the other end of the bracket 22 is penetrated by a through hole 221; the base 21 is provided with a rod body 211 that is perpendicular to the wire rope S to be tested, and the bracket 22 is sleeved on the outside of the rod body 211 through the through hole 221 to realize the hinge connection between the bracket 22 and the base 21; or the other end of the bracket 22 is provided with the rod body, the base 21 is provided with a through hole, and the rod body of the bracket 22 is arranged on the base 2 1, so as to realize the hinge connection between the bracket 22 and the base 21, the base 21 and the wire rope detection device body 100 can be connected by screws, and the bracket 22 and the guide wheel 1 can be connected by a wheel axle, so that the guide wheel 1 can rotate on the bracket 22, and the through hole 221 is sleeved on the outside of the rod body 211, that is, hinge connection can be realized. In some embodiments, in order to prevent the bracket 22 from falling off the rod body 211, a stop plate or a stop block is provided on both sides of the rod body 211.

[0033] Furthermore, the limiting portion 3 includes an adjusting rod 31 and a fastening screw 32; the adjusting rod 31 is located on a side of the bracket 22 away from the steel wire rope S to be tested, the adjusting rod 31 is slidably connected to the bracket 22, and one end is hinged to the steel wire rope detection device body 100, and the bracket 22 drives the adjusting rod 31 to move; the fastening screw 32 is detachably connected to the bracket 22 to limit the adjusting rod 31 on the bracket 22. In this technical solution, the specific sliding connection method between the adjusting rod 31 and the bracket 22 is not limited. For example, the adjusting rod 31 and the bracket 22 can be slidably connected by a sliding groove slider, or by a rod body and a through hole 231, so that when the bracket 22 moves, it will also drive When the adjusting rod 31 moves, the two will slide relative to each other. The present application does not limit the specific connection relationship between the fastening screw 32 and the bracket 22. The detachable connection can be that the fastening screw 32 is screwed on the bracket 22, or the fastening screw 32 can be fixed on the bracket 22 by means of the screw hole bolt matching, etc., to limit the adjusting rod 31. Since the adjusting rod 31 is slidably connected to the bracket 22, the adjusting rod 31 is also hinged to the wire rope detection device body 100. Therefore, when the adjusting rod 31 is limited on the bracket 22, a stable triangular relationship is formed between the bracket 22, the adjusting rod 31 and the wire rope detection device body 100, so that the bracket 22 is limited and fixed and cannot move.

[0034] Furthermore, a hinge groove 212 is provided on the main body 100 of the wire rope detection device, and one end of the adjustment rod 31 is located in the hinge groove 212 to realize the hinge connection between the adjustment rod 31 and the main body 100 of the wire rope detection device. This method is convenient for realizing the hinge connection between the adjustment rod 31 and the main body 100 of the wire rope detection device, and is easy to manufacture and install. Furthermore, the hinge groove 212 is provided on the base 21, and is located on the side of the rod body 211 away from the wire rope S to be tested. In some embodiments, in order to facilitate the movement of the adjustment rod 31 in the hinge groove 212, the end of the adjustment rod 31 located in the hinge groove 212 is spherical, and the spherical shape can reduce the resistance to its movement.

[0035] In some embodiments, a protrusion 23 is provided on the side of the bracket 22 away from the wire rope S to be tested, and a through hole 231 is penetrated through the protrusion 23. The adjusting rod 31 is located on the side of the protrusion 23 away from the hinge groove 212. One end of the adjusting rod 31 passes through the through hole 231 and is located in the hinge groove 212. When the bracket 22 is moved, the adjusting rod 31 is driven to move together, and the two will also slide relative to each other.

[0036] Understandably, the protrusion 23 is provided with a screw hole 232 adapted to the fastening screw 32, the screw hole 232 is connected to the through hole 231, and the end of the fastening screw 32 after being screwed with the screw hole 232 extends into the through hole 231 and abuts against the adjusting rod 31, that is, the fastening screw 32 is screwed on the protrusion 23 through the screw hole 232 to achieve a detachable connection of the fastening screw 32, with a simple structure, and convenient and quick disassembly and installation. When the adjusting rod 31 is limited on the bracket 22, a stable triangular relationship is formed between the bracket 22, the adjusting rod 31 and the wire rope detection device body 100, resulting in the bracket 22 being limited and fixed and unable to move.

[0037] In the technical solution of the present application, a measuring ruler 4 is installed on the protrusion 23, and the measuring ruler 4 is used to measure the length of the adjusting rod 31 located on the side of the protrusion 23 away from the hinge groove 212, so as to achieve the purpose of adjusting the distance between the multiple guide wheels 1, and the adjustment is quick and convenient.

[0038] In some embodiments, an encoder 5 is also included, and the encoder 5 is installed on any one of the guide wheels 1 to measure the travel length of the guide wheel 1, thereby realizing the length measurement of the travel route of the wire rope detection device 1000, and assisting the wire rope detection device 1000 to locate and determine the damaged position of the wire rope.

[0039] In some other embodiments, a wireless communication module 300 is further included. The wireless communication module 300 is installed on the wire rope detection device body 100 to transmit the detection information to the user end. The wireless communication module 300 can be wifi, Bluetooth or 4G, etc.

[0040] During use, the wire rope detection device body 100 is installed on the wire rope S to be tested, and the guide wheel 1 is driven to move together by adjusting the connecting part 2. When the guide wheel 1 touches the wire rope S to be tested, the connecting part 2 is stopped from moving, and the connecting part 2 is limited and fixed by the limiting part 3, that is, the guide wheel 1 is limited at the required position. After the debugging of all guide wheels 1 is completed, an external force is applied to the wire rope detection device body 100, and the wire rope detection device 1000 can be moved along the length direction of the wire rope S to be tested. When the wire rope detection device 1000 needs to be disassembled, the limiting part 3 is made to not limit the connecting part 2, and then the wire rope detection device body 100 can be disassembled.
