[0031] Reference Figure 1-5In this embodiment, the steering assembly 3 is arranged above the mobile frame 1. The steering assembly 3 is used to change the direction of the wire threading in the pipeline. When encountering a curved pipeline, the retracting rope 22 can be pushed in along the curved direction of the pipeline. The steering assembly 3 includes a support block 31 and a rotating column 32. The support block 31 and one end of the retracting rope 22 are fixed. Inner grooves 33 are provided on both sides of the support block 31. The top and bottom of the two inner grooves 33 are provided with limited leakage grooves 34. When particle foreign matter enters the inner groove 33, it will fall out through the limited leakage groove 34 to prevent the particle foreign matter from gathering. The two inner grooves 33 are A first spring 35 is fixed inside, and an extrusion plate 36 is slid inside the two inner grooves 33. The two extrusion plates 36 are fixedly connected to one end of the two first springs 35 respectively. One end of the rotating column 32 rotates on the inner side of the support block 31, and two threading pieces 37 are fixed to the other end of the rotating column 32. Extrusion arc plates 38 are fixed on both sides of the rotating column 32. The two extrusion arc plates 38 are respectively located on both sides of the two extrusion plates 36. When the first spring 35 is at its original length, the two extrusion plates 36 respectively limit the positions of the two extrusion arc plates 38, so that the rotating column 32 is in a straight state with the support block 31.

[0032] Reference Figure 1-5 In this embodiment, the threading member 37 includes a fixing plate 39. The fixing plates 39 of the two threading members 37 are fitted and fixed on one end of the rotating column 32. The two threading members 37 are symmetrically arranged in reverse. A clamping plate 310 is arranged above the fixing plate 39. A plurality of rolling grooves 311 are provided on the side opposite to the clamping plate 310. Balls 312 are arranged inside the plurality of rolling grooves 311. When the balls 312 fit the inner wall of the pipeline in the pipeline, they will roll when the retracting rope 22 and the steering assembly 3 continue to move forward, which effectively helps the retracting rope 22 to pass through the pipeline more smoothly.

[0033] Reference Figure 1-5In this embodiment, both sides of the top of the fixing plate 39 are provided with special-shaped limiting grooves 313, and a certain inclination slope is set below the special-shaped limiting grooves 313. Both sides of the bottom of the clamping plate 310 are provided with mounting grooves 314, and the insides of the two mounting grooves 314 are fixed with second springs 315. Special-shaped limiting heads 316 are slidably arranged inside the two mounting grooves 314. The shape of the special-shaped limiting heads 316 is adapted to the special-shaped limiting grooves 313. When the second springs 315 are at their original length, the special-shaped limiting heads 316 are stuck in the special-shaped limiting grooves 313. The insides of the two mounting grooves 314 are provided with through grooves 315. 7. An L-shaped adjustment plate 318 is fixed on the top of the two special-shaped limit heads 316. Grooves 319 are provided on both sides of the top of the clamping plate 310. The two L-shaped adjustment plates 318 extend to the inside of the two grooves 319 respectively. A groove body 320 is provided on the top of the rotating column 32. The internal thread of the groove body 320 is connected with a screw rod 321. One end of the screw rod 321 extends to the inside of the fixed plate 39. A wire clamping plate 322 is fixed to one end of the screw rod 321. The position of the wire clamping plate 322 in the fixed plate 39 can be changed by rotating the screw rod 321, so that the wires can be fixed in the fixed plate 39.

[0034] Reference Figure 1-5 , In this embodiment, the traction assembly 6 includes two support plates 61 fixed on the top of the mobile frame 1, two rotating rods 62 are rotated between the two support plates 61, and the outsides of the two rotating rods 62 are both slidably limited wheels 63, and the retracting rope 22 is arranged between the two limited wheels 63, and the outsides of the two rotating rods 62 are both sleeved with two third springs 64, and the two third springs 64 outside each rotating rod 62 are respectively arranged on both sides of the limited wheels 63, and one side of one of the support plates 61 has two gears 65 that rotate, and the two gears 65 are meshed to realize the reverse rotation of the two rotating rods 62 and the two limited wheels 63, and a motor 66 is fixed on one side of the other support plate 61, and one end of the output shaft of the motor 66 is fixed to one end of one of the rotating rods 62, and support arms 67 are fixed on both sides of the two limited wheels 63, and a stabilizing sleeve 68 is fixed between one ends of the four support arms 67, and the retracting rope 22 is inserted in the stabilizing sleeve 68, so that the retracting rope 22 of the section between the limited wheel 63 and the stabilizing sleeve 68 is always in a straight state.

[0035] When in use, the motor 66 and the driving motor are used to respectively drive one of the rotating rods 62 and the winding wheel 21 to rotate, the winding wheel 21 releases the retractable rope 22, and the rotating rod 62 realizes the reverse rotation of the two rotating rods 62 and the two limiting wheels 63 through two meshing gears 65, so as to push the retractable rope 22 and the steering assembly 3 into the pipeline. When the retractable rope 22 and the steering assembly 3 pass through the pipeline and encounter a turning place, the fixed plate 39 and the clamping plate 310 will abut against the inner wall of the pipeline. When the threading member 37 continues to move forward, the balls 312 on the fixed plate 39 and the clamping plate 310 will slide along the inner wall of the pipeline and bend at the curved place of the inner wall of the pipeline. When bending, the rotating plate 39 and the clamping plate 310 will slide along the inner wall of the pipeline and bend at the curved place of the inner wall of the pipeline. The column 32 deflects at the rotating connection of the support block 31. During the deflection, an extrusion arc plate 38 on the rotating column 32 located on the inner side of the deflection direction will push the extrusion plate 36 close to it. The extrusion plate 36 squeezes the first spring 35 connected to it. After passing the bending position of the pipeline, the rotating column 32 is restored to its original state (that is, the rotating column 32 and the support block 31 are in a straight line) under the elastic force of the first spring 35. After the threading member 37 is moved out of the pipeline, the wires are inserted into the fixing plate 39 and the clamping plate 310, and the wires are fixed through the clamping plate 322. Then, the driving motor and the motor 66 are reversed to drive the retracting rope 22 to reel in, and the retracting rope 22 drives the wires back through the pipeline.

[0036] During the retraction and release of the retractable rope 22, according to the position and traction of the retractable rope 22 on the reel 21, the limiting wheel 63 will be driven to move on the rotating rod 62 to prevent the retractable rope 22 from being bent and worn on the limiting wheel 63 when the retractable rope 22 is reeled on the reel 21 to a position that does not correspond to the limiting wheel 63. During the movement, the retractable rope 22 is limited and subjected to the reaction force of the third spring 64, so that it will not be pulled and deviated by the retractable rope 22 and cannot return to the center position. At the same time, the stabilizing sleeve 68 and the limiting wheel 63 move together to keep the retractable rope 22 between them in a straight state, to prevent the retractable rope 22 from being constantly deviated due to traction when passing through the pipeline, affecting the pipeline threading efficiency.

[0037] During use, some foreign matter may get on the outside of the ball bearing 312, which may get stuck in the rolling groove 311 and block the ball bearing 312 from rolling. Later, the L-shaped adjustment plate 318 and the groove 319 may be pinched to move the L-shaped adjustment plate 318 to one side of the through groove 317 and drive the special-shaped limiting head 316 to move to the other side of the inner wall of the special-shaped limiting groove 313, and the second spring 315 may be squeezed to move the special-shaped limiting head 316 out of the limiting area of ​​the special-shaped limiting groove 313, so that the pinched L-shaped adjustment plate 318 can be pulled upward , separate the clamping plate 310 and the fixed plate 39, expose the ball 312, clean the ball 312 and the rolling groove 311, and then install the ball 312 into the rolling groove 311, press the special-shaped limiting head 316 into the corresponding special-shaped limiting groove 313, and the special-shaped limiting head 316 will compress the second spring 315 along the extrusion of the inclined surface until the special-shaped limiting head 316 is released and the second spring 315 clamps it into the special-shaped limiting groove 313, and the installation of the fixed plate 39, the clamping plate 310 and the ball 312 is completed.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
