DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0028] A cable construction power traction device, such as Figure 1-Figure 6 As shown, it includes a traction machine body 1, a connecting rope 2, a fixing seat 3, an externally threaded connecting seat 4, an internally threaded guide sleeve 5, a connecting frame 51, a wire mesh sleeve 6, a fixing mechanism and a cleaning mechanism. The traction machine body 1 is wound with a connecting rope 2, the end of the connecting rope 2 is connected to a fixing seat 3, the fixing seat 3 is rotatably connected to an externally threaded connecting seat 4, the externally threaded connecting seat 4 is threadedly connected to an internally threaded guide sleeve 5, the right side of the internally threaded guide sleeve 5 is connected to a connecting frame 51, the middle of the right side of the internally threaded guide sleeve 5 is connected, the fixing seat 3, the externally threaded connecting seat 4 and the internally threaded guide sleeve 5 constitute a connecting end, and the internally threaded guide sleeve 5 is provided with a fixing mechanism for fixing the cable 100 and a cleaning mechanism for cleaning impurities in the pipeline 200.

[0029] like Figure 3 and Figure 4 As shown, the fixing mechanism includes a connecting gear 71, a locking rod 72, a connecting rack 73 and a movable plate 74. The right side of the internally threaded guide sleeve 5 is rotatably connected with a plurality of connecting gears 71 at uniform intervals along the circumferential direction, and each connecting gear 71 is connected with a locking rod 72. A movable plate 74 is slidably connected in the internally threaded guide sleeve 5. The movable plate 74 is rotatably connected to the externally threaded connecting seat 4 so that when the externally threaded connecting seat 4 moves in the internally threaded guide sleeve 5, it can drive the movable plate 74 to move together. The right side of the movable plate 74 is evenly connected with connecting racks 73 with the same number as the connecting gears 71 along the circumferential direction. The connecting racks 73 mesh with the connecting gears 71 so that the connecting racks 73 can drive the connecting gears 71 to rotate when moving, thereby driving the locking rod 72 to rotate and clamp the cable 100, so as to fix the cable 100.

[0030] like Figure 5 As shown, the cleaning mechanism includes an annular liquid sac 81, an infusion tube 82, a large piston plate 83 and a threaded rod 84. The annular liquid sac 81 is connected to the internal threaded guide sleeve 5. A liquid storage chamber is opened in the middle of the right side of the internal threaded guide sleeve 5. The large piston plate 83 is slidably connected in the liquid storage chamber. A plurality of infusion tubes 82 are evenly spaced along the circumferential direction on the internal threaded guide sleeve 5. Both ends of the infusion tube 82 are connected to the liquid storage chamber and the annular liquid sac 81 respectively, so that the large piston plate 83 can move in the liquid storage chamber and inject the liquid inside it into the annular liquid sac 81 through the infusion tube 82, so that the annular liquid sac 81 expands and presses against the inner wall of the pipeline 200. The connecting frame 51 is connected to a threaded rod 84 by threads, and the threaded rod 84 is rotatably connected to the large piston plate 83.

[0031] When the cable 100 needs to be pulled, the device can be used. When in use, first control the traction machine body 1 to loosen the connecting rope 2, then pull out the connecting end and pass it into the pipe 200 from one side of the pipe 200 and pass it through the other side of the pipe 200. After passing it out, put the wire mesh sleeve 6 on the outside of the cable 100, and then rotate the external thread connection seat 4 to make the external thread connection seat 4 move to the left. When the external thread connection seat 4 moves, it drives the movable plate 74 to move. When the movable plate 74 moves, it can drive the connecting rack 73 to move together, and the connecting rack 7 When moving, the connecting gear 71 is driven to rotate, thereby driving the locking rod 72 to rotate, so that the locking rod 72 is pressed against the cable 100 to help fix the cable 100. After the cable 100 is fixed, the threaded rod 84 is rotated to drive the large piston plate 83 to move leftward through the thread. When the large piston plate 83 moves leftward, the liquid in the liquid storage chamber 85 is injected into the annular liquid bag 81 through the infusion tube 82, so that the annular liquid bag 81 expands to the same size as the inner wall of the pipeline 200. At this time, the tractor body 1 is controlled to retract the connecting rope 2, and when retracting, it can The cable 100 is pulled into the pipe 200 and passed through the pipe 200 by connecting the end and the locking rod 72. When the internal thread guide sleeve 5 moves, the annular liquid capsule 81 can be driven to move. When the annular liquid capsule 81 moves, impurities attached to the inner wall of the pipe 200 can be scraped out to prevent the impurities from rubbing against the cable 100 and causing the cable 100 to be worn, thereby protecting the cable 100. The cable 100 is pulled until the entire cable 100 passes through the pipe 200. Then, the external thread connector 4 is rotated to the right through the thread. When the connecting rack 73 is moved, the movable plate 74 can be used to drive the connecting rack 73 to move, and the connecting rack 73 can drive the connecting gear 71 to rotate in the opposite direction to open the locking rod 72, and then the cable 100 can be loosened. In this way, the device can be used to pull the cable 100. During the traction process, the locking rod 72 can be used to assist in fixing, and the fixing effect is better. During the traction process, the annular liquid bag 81 can be used to assist in scraping off impurities on the inner wall of the pipe 200 to avoid friction between the impurities and the cable 100, thereby protecting the cable 100.

[0032] like Figure 6 and Fig.10As shown, it also includes a supporting mechanism, which includes a movable seat 91, a contact ball 92, a cylinder body 93, a small piston plate 94 and a connecting pipe 95. The right side of the internal threaded guide sleeve 5 is evenly spaced along the circumferential direction with cylinder bodies 93 that are the same number as the infusion tubes 82. A small piston plate 94 is slidably connected in each cylinder body 93. The small piston plate 94 is connected to a movable seat 91. The movable seat 91 extends out of the cylinder body 93 and is slidably connected to the cylinder body 93. The part of the movable seat 91 that extends out of the cylinder body 93 is rotatably connected to the contact ball 92. A connecting pipe 95 is connected between the cylinder body 93 and the infusion tube 82 to guide the liquid at the infusion tube 82 to the connecting pipe 95.

[0033] When the liquid passes through the infusion tube 82, some liquid will enter the cylinder body 93 through the connecting tube 95, thereby squeezing the small piston plate 94 to move outward. When the small piston plate 94 moves, it can drive the contact ball 92 to move through the movable seat 91. When the annular liquid sac 81 expands to contact the inner wall of the pipe 200, the contact ball 92 can also contact the inner wall of the pipe 200. Subsequently, during the movement of the connecting end on the inner wall of the pipe 200, the contact ball 92 can contact the inner wall of the pipe 200 to assist in supporting it, so that the connecting end moves in the center of the pipe 200, avoiding friction between the connecting end and the inner wall of the pipe 200.

[0034] like Figure 7 and Fig.10 As shown, a friction pad 10 is also included. The friction pad 10 is connected to the annular liquid sac 81. When the annular liquid sac 81 expands, it will contact the inner wall of the pipe 200 through the friction pad 10. Then, the impurities on the inner wall of the pipe 200 are scraped off by the friction pad 10, thereby protecting the annular liquid sac 81 and preventing the annular liquid sac 81 from being damaged by long-term friction with the pipe 200.

[0035] like Figure 7 , Figure 8 and Fig.10 As shown, a scraping mechanism is also included, which includes a driving motor 111, an annular gear ring 112, a friction scraper 113 and a driving gear 114. The driving motor 111 is installed on the internal threaded guide sleeve 5, and the driving gear 114 is connected to the output shaft of the driving motor 111. The internal threaded guide sleeve 5 is rotatably connected with the annular gear ring 112, and the annular gear ring 112 is meshed with the driving gear 114, so that the driving motor 111 can drive the annular gear ring 112 to rotate through the driving gear 114. A plurality of detachable and replaceable friction scrapers 113 are evenly spaced along the circumferential direction on the annular gear ring 112, and the friction scrapers 113 can resist the inner wall of the pipe 200. When rotating, the friction scrapers 113 can scrape off impurities attached to the inner wall of the pipe 200.

[0036] When the connecting end is located in the pipe 200, the friction scraper 113 can contact the inner wall of the pipe 200, and then the driving motor 111 can be controlled to drive the driving gear 114 to rotate. When the driving gear 114 rotates, it can drive the annular gear ring 112 to rotate. The rotation of the annular gear ring 112 can drive the friction scraper 113 to rotate, thereby scraping off impurities attached to the pipe 200 to prevent impurities from adhering to the inner wall of the pipe 200 and scratching the cable 100. In actual operation, friction scrapers 113 of different specifications can also be replaced according to the size of the pipe 200.

[0037] like Fig. 9 As shown, it also includes a fixed block 121 and a convex shaft 122. The fixing block 121 is slidably connected to the right side of the locking rod 72. The convex shaft 122 is connected to the front and rear sides of the fixing block 121. The front and rear sides of the right side of the locking rod 72 are provided with oblique grooves, and the convex shaft 122 is located in the oblique groove so that the locking rod 72 can squeeze the convex shaft 122 through the oblique groove when moving.

[0038] When the locking rod 72 moves inward, it will drive the fixing block 121 to press against the cable 100 to fix the cable 100. Then, when the traction machine body 1 retracts the connecting rope 2, the locking rod 72 moves together. At this time, since the fixing block 121 and the pipeline 200 cable 100 move slower than the locking rod 72, the movement of the locking rod 72 can squeeze the convex shaft 122 through the inclined groove, thereby increasing the friction between the fixing block 121 and the cable 100. In this way, the cable 100 can be fixed by the fixing block 121, and when fixed, as the locking rod 72 moves, the friction between the fixing block 121 and the cable 100 can be increased, thereby improving the fixing effect and preventing the cable 100 from falling off.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
