This technology discloses a device for laying cables in a duct, including a traction device and an auxiliary structure. The traction device is detachably connected to one end of the cable, and the auxiliary structure is sleeved on the outer wall of the cable. The traction device includes a traction structure that abuts against the inner wall of the duct. A clamping structure is fixedly connected to one end of the traction structure near the cable, and the clamping structure is detachably connected to the cable. This technology has the following technical effects: "the auxiliary structure reduces friction and avoids damage to the conductor insulation layer; the traction structure adapts to ducts of different diameters and avoids slippage; the clamping structure clamps the end of the cable, making connection convenient."

[0004] In actual use, the cable laying device in the above-mentioned duct uses three electric telescopic rods and three motors to adapt to and move the duct. The multiple electric components increase the manufacturing cost, operating cost and subsequent maintenance cost. In addition, the energy consumption of the multiple electric components is also high, which affects the device's endurance. Utility Model Content

The traction mechanism 2 includes:

[0026] The main component 21 includes a front seat 212 and a rear seat 213, which are respectively fixed at the front and rear ends of the housing 211;

[0027] The adjustment assembly 22 includes three circumferentially distributed front brackets 221 hinged on the front seat 212, a front guide wheel 222 rotatably mounted on the outer end of the front bracket 221, and a drive gear 223 fixed on the front guide wheel 222.

[0028] The moving component 23 includes a worm gear 231 rotatably mounted inside the front seat 212, a worm wheel 232 rotatably mounted at the inner end of the front bracket 221 and meshing with the worm gear 231 for transmission, and a transmission gear 233 fixed on the worm wheel 232 meshing with the drive gear 223 for transmission.

[0029] In this embodiment, the worm gear 231 is driven by the motor 234 to rotate the worm wheel 232. The worm wheel 232 drives the guide wheel 222 to rotate through the transmission gear 233 and the drive gear 223. This allows the traction mechanism 2 to move along the inside of the pipe. Only one motor 234 is needed to achieve the adaptation and movement with the pipe.

[0030] Specifically, the adjustment assembly 22 also includes a guide rod 224 fixed inside the rear seat 213, a sliding carriage 225 mounted on the guide rod 224, three circumferentially distributed supports 226 hinged on the rear seat 213, a crossbeam 227 pivotally connected to the outer end of the support 226, and the other end of the crossbeam 227 pivotally connected to the front support 221, and a rear guide wheel 228 rotatably mounted on the outer end of the support 226; three circumferentially distributed rear supports 229 hinged on the housing 211, and the outer end of the rear supports 229 pivotally connected to the outer end of the support 226; and a spring 2210 mounted on the guide rod 224.

[0031] In this embodiment, the spring 2210 pushes the slide 225 forward along the guide rod 224 by the pressure of the spring 2210. The slide 225 drives the cross frame 227 through the support frame 226. The cross frame 227, with the cooperation of the rear support 229 and the front support 221, drives the rear guide wheel 228 and the front guide wheel 222 to be pushed outward so that they contact the inner wall of the pipe. By adapting to the pipe, the stability during the movement is improved.

[0032] Specifically, the moving component 23 also includes a motor 234 installed inside the housing 211 for driving the worm gear 231, and a battery 235 installed inside the housing 211.

[0033] In this embodiment, the battery 235 supplies power to the motor 234, and the motor 234 drives the worm gear 231 to rotate.

[0034] Specifically, the fixing mechanism 3 includes a cylinder 31 installed at the rear end of the traction mechanism 2, a tightening head 32 installed inside the cylinder 31, a tightening sleeve 33 installed inside the cylinder 31 and fitted onto the tightening head 32, and a cylinder cover 34 threadedly installed at the rear end of the cylinder 31.

[0035] In this embodiment, by passing the cable 1 through the tube cover 34 and inserting it into the clamping head 32 inside the tube body 31, and then rotating and tightening the tube cover 34 to push the clamping sleeve 33 to squeeze the clamping head 32, the clamping head 32 clamps and fixes the cable 1.

[0036] Specifically, the main body component 21 also includes a threaded seat 214 fixed to the rear end of the rear seat 213, and the cylinder 31 is threadedly installed with the rear seat 213.

[0037] In this embodiment, the fixing mechanism 3 can be disassembled and installed from the traction mechanism 2, making it convenient to replace the fixing mechanism 3 with a suitable one according to the specifications of the cable 1.

[0038] The working principle and usage process of this utility model are as follows: First, according to the specifications of the cable 1, replace the appropriate fixing mechanism 3 and install it on the threaded seat 214. Then, pass the cable 1 through the tube cover 34 and insert it into the tightening head 32 inside the tube body 31. Then, rotate and tighten the tube cover 34 to push the tight sleeve 33 to squeeze the tightening head 32, so that the tightening head 32 clamps and fixes the cable 1.

[0039] Then, the traction mechanism 2 is placed in the pipe, and the slide 225 is pushed forward along the guide rod 224 by the pressure of the spring 2210. The slide 225 drives the cross frame 227 through the support frame 226. The cross frame 227 drives the rear guide wheel 228 and the front guide wheel 222 to open outward under the cooperation of the rear support 229 and the front support 221, so that they contact the inner wall of the pipe.

[0040] Finally, the worm gear 231 is driven by the motor 234 to rotate the worm wheel 232. The worm wheel 232 drives the guide wheel 222 to rotate through the transmission gear 233 and the drive gear 223. This allows the traction mechanism 2 to move along the inside of the pipe. Only one motor 234 is needed to achieve the adaptation and movement with the pipe.
