[0022] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be further described in detail below with reference to the accompanying drawings of the embodiments of this utility model.

[0023] Reference Figure 1 , Figure 2 As shown, the present invention provides a traction device for a pipeline repair ultraviolet curing repair vehicle, which includes a wire coil 1, a wire coil frame 2, a servo motor 3, a support structure, and a wire coil limiting structure. The wire coil 1 is rotatably mounted on the wire coil frame 2, the servo motor 3 is fixedly mounted on the wire coil frame 2 and its output end is connected to the shaft of the wire coil 1 for transmission, and the support structure is mounted on the wire coil frame 2.

[0024] The wire reel limiting structure includes a positioning gear 7 and a limiting component. The positioning gear 7 is fixedly mounted on the shaft of the wire reel 1, and the limiting component is detachably mounted on the wire reel frame 2. The limiting component can interfere with the positioning gear 7 to prevent the positioning gear 7 from rotating.

[0025] In some examples, the limiting element includes an L-shaped rectangular rod 8, one end of which can be slidably inserted into the side wall of the wire reel 2 and the other end of which has a slot (not shown) into which the teeth of the positioning gear 7 can be embedded.

[0026] During transportation, the staff can insert one end of the L-shaped rectangular rod 8 into the wire reel frame 2, so that the corresponding teeth of the positioning gear 7 are engaged in the slot. The L-shaped rectangular rod 8 cannot rotate relative to the wire reel frame 2. Therefore, the positioning gear 7 is restricted by the L-shaped rectangular rod 8 and cannot rotate either. The positioning gear 7 is fixedly mounted on the shaft of the wire reel 1. The two move synchronously, so the wire reel 1 cannot rotate. This avoids the situation where the wire reel 1 rotates due to the vibration of the vehicle after the servo motor 3 stops, which would cause the cable on the wire reel 1 to be pulled and messed up.

[0027] A hook 4 is installed on the end of the wire reel 1 for easy hooking onto the UV curing repair cart. Two V-shaped auxiliary wheels 6 are rotatably mounted on the wire reel frame 2. The cable of the wire reel 1 passes between the grooves of the two V-shaped auxiliary wheels 6, which can prevent the cable on the wire reel 1 from swinging with the direction of the coil during traction, thus avoiding unstable traction direction. A controller 31 electrically connected to the servo motor 3 is installed on the wire reel frame 2. The controller 31 can control the starting, stopping, direction, and speed of the servo motor 3, making it convenient for operators.

[0028] like Figure 1 , 3 As shown in Figure 4, the support structure includes four anti-pull auxiliary brackets 5 installed at the four corners of the wire reel frame 2. Each anti-pull auxiliary bracket 5 includes a single-opening telescopic main rod 51, a main rod cover 52, a threaded sub-rod 53, and an anti-slip support plate 54. The top end of the single-opening telescopic main rod 51 is rotatably connected to the wire reel frame 2 by a pin. The main rod cover 52 is threadedly connected to the bottom end of the single-opening telescopic main rod 51. The threaded sub-rod 53 passes through the main rod cover 52 and is slidably inserted into the single-opening telescopic main rod 51. The outer surface of the threaded sub-rod 53 is threadedly connected to the inner surface of the main rod cover 52. The anti-slip support plate 54 is rotatably connected to the bottom end of the threaded sub-rod 53.

[0029] During traction operations, workers need to rotate the threaded rod 53 according to the ground conditions. Since the threaded rod 53 and the main rod cover 52 are threaded together, the threaded rod 53 can slide relative to the single open telescopic main rod 51, thereby adjusting the effective length of the threaded rod 53 and the single open telescopic main rod 51 as a whole. After the adjustment is appropriate, a suitable fixing surface is selected, and the threaded rod 53 is rotated so that the anti-slip support plate 54 is supported on the ground.

[0030] In some examples, to prevent the threaded rod 53 from detaching due to excessive stretching, an anti-detachment post 531 is provided at the top of the threaded rod 53. The anti-detachment post 531 can interfere with the main rod cover 52, thereby preventing the threaded rod 53 from sliding out of the single-opening telescopic main rod 51. Furthermore, to ensure that the anti-pull auxiliary bracket 5 does not affect the normal loading and unloading of the wire reel 2 when not in use, the minimum effective length of the threaded rod 53 and the single-opening telescopic main rod 51 is less than the height of the connection position between the single-opening telescopic main rod 51 and the wire reel 2.

[0031] In summary, the specific workflow of this device is as follows: Place the wire reel frame 2 on one side of the well opening, unscrew the threaded rod 53 to fix it obliquely on the road surface, select a suitable fixing surface, support the anti-slip support plate 54 on the selected fixing surface, then pull out the L-shaped rectangular rod 8, pull out the wire end of the wire reel 1, and pass it through the epoxy resin pipe through the traction robot. Then, hang the hook 4 at the top of the wire end on the ultraviolet curing lamp at the other end. Then, select a suitable speed through the controller 31 and start the servo motor 3 to recycle the cable of the wire reel 1. During the traction process, the ultraviolet curing lamp will heat the epoxy resin pipe, making it stick to the damaged pipe. Finally, disconnect the connection between the ultraviolet curing lamp and the hook 4, and recycle the wire reel 1 to the V-shaped auxiliary wheel 6. Insert the L-shaped rectangular rod 8 back into the side of the wire reel frame 2 for fixation, and the traction operation is completed.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
