These issues mainly include wear and breakage risks, failure caused by overloading, corrosion and rust, improper installation and maintenance, fatigue damage and aging, the impact of temperature changes, improper operation and lack of regular inspections.

[0003] In the prior art, the damage of a wire rope is often detected by a wire rope detection device, for example, the wire rope detection device with publication number CN108828056A, which sets a circumferential magnetic field around the wire rope to be tested and a radial magnetic field and an axial magnetic field that wrap the circumferential magnetic field, thereby reflecting the changes in the spatial magnetic field distribution caused by the internal damage of the wire rope from multiple spatial angles and in all directions, and detects the damage based on the change information of the spatial magnetic field distribution.

[0004] However, the current detection methods for wire ropes mostly use fixed detection devices or handheld detection devices for detection. During the long-term static wire rope detection, the wire rope may be tilted or vertical, and the traditional fixed detection device or handheld detection device cannot move autonomously on the wire rope, which will lead to problems such as difficult detection operation and low detection efficiency.

[0032] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-5 As shown, the traction device for the wire rope detection device of the utility model comprises a bracket 1, a drum 2, a driving member 3 and a pull rope 4.

[0034] Bracket 1 is an anchoring component in the device and needs to be fixed relative to the ground. Accordingly, multiple mounting holes are opened on the bracket 1, and in order to improve the installation matching capability of the bracket 1, the mounting holes are all set as waist-round holes. When detecting an inclined wire rope, the bracket 1 can be fixed at the highest horizontal point of the wire rope, and some wire rope detection devices will clamp the wire rope during the detection process. At this time, the bracket 1 can be set at the lowest horizontal position or the highest horizontal position of the wire rope, and even two traction devices can be installed to perform bidirectional traction on the wire rope detection device. Under normal circumstances, the bracket 1 is directly fixed to the ground with expansion bolts. It should be noted that the bracket 1 can also be placed in a mobile manner in some application scenarios without being fixed.

[0035] The drum 2 is rotatably arranged on the bracket 1 with its axis as the rotation center. The axis of the drum 2 needs to be perpendicular to the length direction of the wire rope to be detected. In this embodiment, the drum 2 needs to have a certain load-bearing capacity. It is preferably formed by rolling a stainless steel plate to avoid deformation of the drum 2 during the pulling process, which may cause inconsistent traction speed of the detection device.

[0036] The driving member 3 is fixed on the bracket 1, and the driving member 3 has a rotating output end, and the rotating output end is transmission-connected to the reel 2. On the bracket 1, there are two side surfaces, and the two side surfaces are respectively located on both sides of the axis of the reel 2. The driving member 3 is fixed on one of the side surfaces and connected to the reel 2 through the rotating output end, so that the reel 2 can rotate.

[0037] In this embodiment, the driving member 3 is preferably a reduction motor, and its output end is the rotation output end of the driving member 3. The reduction motor converts high speed into large torque to drive the drum 2 to rotate to achieve the traction operation of the wire rope detection equipment.

[0038] One end of the pull rope 4 is wound on the drum 2, and the other end is fixed to the wire rope detection device, so that when the drum 2 reels the pull rope 4, it drives the wire rope detection device to move on the wire rope. The pull rope 4 is preferably a nylon rope. Nylon rope has high strength and tensile resistance, can withstand large traction without breaking easily, and compared with wire ropes or chains of the same strength, nylon ropes are lighter and easier to carry and operate.

[0039] By setting up a small traction device, the detection device can move on the wire rope to be detected, thereby improving the safety and efficiency of wire rope detection. The traction device is connected to the wire rope detection device, so that the wire rope detection device can be applied to a wider range of wire rope scenarios, reducing the workload caused by operating difficulties and long-distance measurements. It can also be retracted and released autonomously, achieving semi-intelligence, and solving the problem that in the detection of long-term static wire ropes, the traditional fixed detection device or the handheld detection device may face difficulties in operation and the detection device cannot move autonomously on the wire rope, because the wire rope may be in an inclined or vertical state.

[0040] In addition, when the pull rope 4 is connected to the wire rope detection device, a carabiner is provided at the rope end for connecting to a lifting eye buckle. When the traction device is not needed, the traction device and the detection device can be separated by simply loosening the carabiner. An installation hole for installing the lifting eye buckle is provided on the detection device, and the lifting eye buckle is fixed to the detection device with screws. For a detection device with a portable component, its portable position can be directly used as the connection position of the carabiner.

[0041] In this embodiment, the bracket 1 includes two supports 11 and multiple cross bars 12. The two supports 11 are relatively fixed, and the reel 2 is arranged between the two supports 11. The multiple cross bars 12 are fixed between the two supports 11 and are parallel to each other. The two supports 11 are arranged in an L shape, and the mounting holes are opened at the bottom of the supports 11. The supports 11 can be directly cut and bent into steel plates. The cross bars 12 are provided with bolt mounting holes at both ends. The cross bars 12 are fixed between the two supports 11 by bolts to form a stable connection structure. In addition to reinforcing the structure of the bracket 1, the multiple cross bars 12 can also block when the pull rope 4 breaks, thereby preventing safety problems caused by the breakage of the traction rope during use. In addition, the cross bars 12 can also provide space for the operator to hold the hand when carrying.

[0042] A rotating shaft 5 is also provided between the two supports 11, and both ends of the rotating shaft 5 are mounted on the bracket 1 through bearings, that is, both ends of the rotating shaft 5 are respectively mounted on the two supports 11 through two bearings, and the rotating shaft 5 is located at the rotation center of the reel 2, and the reel 2 is fixed on the outside of the rotating shaft 5, and the rotating shaft 5 is connected to the driving member 3 through transmission. By setting the rotating shaft 5, the mechanical wear of the reel 2 during rotation is reduced, and at the same time, it is convenient to assemble the reel 2 between the two supports 11.

[0043] In addition, an encoder 6 is fixed on the bracket 1, and the encoder 6 is located on the extension line of the axis of the drum 2. The rotating end of the encoder 6 is fixed to the shaft 5 so that the encoder 6 can collect the rotation information of the drum 2. The encoder 6 is used to measure the position, rotation speed and rotation direction of the shaft 5. Specifically, the mechanical movement of the shaft 5 is converted into an electrical signal, and then the electrical signal is transmitted to the subsequent processing equipment for signal interpretation to obtain the motion data of the shaft 5. By obtaining the rotation data of the shaft 5, the rotation condition of the drum 2 can be obtained, and then the winding length of the pull rope 4 can be obtained, so as to realize the position calibration and visual position display of the wire rope detection device, and provide data support for semi-automatic operation. It should be noted that when the encoder 6 is fixed to the outside of the bracket 1, a U-shaped mounting frame must be installed first, and then the encoder 6 must be installed on the U-shaped mounting frame. The encoder 6 cannot be directly fixed to the bracket 1.

[0044] The encoder 6 is directly arranged on the outside of the bracket 1, and there is a great risk of damage. Therefore, a protective frame 7 is also provided in this embodiment. The protective frame 7 is fixed to the outside of the bracket 1 and covers the outside of the encoder 6. The protective frame 7 is formed by bending a metal plate and is arranged in a U shape as a whole. The size is larger than the encoder 6. The protective frame 7 is then fixed to the corresponding support 11 by screws. The protective frame 7 can protect the encoder 6 from contacting external hard objects during use or transportation, thereby preventing the encoder 6 from being damaged due to collision.

[0045] In this embodiment, in order to fix the pull rope 4 on the drum 2, a rope locking member 8 is further provided. The rope locking member 8 is fixed on the outer wall of the drum 2. One end of the pull rope 4 wound on the drum 2 is fixed to the drum 2 by the rope locking member 8. The rope locking member 8 is preferably made of metal and welded to the drum 2. After the end of the pull rope 4 is fixed by the rope locking member 8, the pull rope 4 is wound to the outside of the drum 2 to prevent the pull rope 4 from sliding or detaching from the drum 2 during the force application process.

[0046] Specifically, the rope locking member 8 is cylindrical as a whole and is welded to the drum 2 on the outside. A through hole 81 and a threaded hole 82 are provided on the rope locking member 8. The pull rope 4 passes through the through hole 81 and passes through the rope locking member 8. The pull rope 4 is tightened and fixed in the rope locking member 8 by a screw inserted into the threaded hole 82. In order to prevent the pull rope 4 from being broken due to excessive local force at the connection with the rope locking member 8 during the pulling process, in the present embodiment, three rope locking members 8 are provided and are arranged and fixed along the same arc on the outside of the drum 2, so that the pull rope 4 passes through the three rope locking members 8 in sequence.

[0047] In this embodiment, the reel 2 includes a cylinder body 21 and two protective discs 22. The cylinder body 21 is arranged on the bracket 1. The two protective discs 22 are respectively fixed on both sides of the axis of the cylinder body 21 to prevent the pull rope 4 wound on the cylinder body 21 from escaping from the cylinder body 21. During the winding process of the pull rope 4, the two protective discs 22 can contact with the pull rope 4 to correct the winding path of the pull rope 4 to prevent the pull rope 4 from getting stuck in the gap between the reel 2 and the bracket 1.

[0048] In addition, in the present embodiment, a chassis 9 is also provided, wherein the chassis 9 is fixed on the bracket 1 and is electrically connected to the driving member 3. The chassis 9 includes a switch, an indicator light, a control module and a battery. The switch is used for power control, the indicator light is used for displaying the working status, and the provided battery enables the device to be carried and operated without power supply, thereby further improving the portability of the device.
