Technical Field

[0001] This utility model relates to the field of tube threading machine technology, and more particularly to a tube threading machine. Background Technology

[0002] Electrical engineering is related to the production, transmission, and distribution of electrical energy. With the rapid development of the power and information industries, environmental protection issues have gradually attracted people's attention. Underground cabling has been widely promoted in the construction and renovation of urban power grids, leading to the increasingly widespread application of steel pipes for cable burial. Steel pipes for cable burial are a type of conduit used to protect cables, distinguish cable functions, facilitate wiring, and facilitate maintenance. When laying cables, the cables need to be threaded into the steel pipes before being buried in underground trenches. A conduit-threading machine is needed to assist in the cable threading operation.

A first sliding groove is formed through one side of a fixed rod. A crossbar is slidably connected to one end of the first sliding groove. A scraper is fixedly connected to the side of the crossbar opposite to the fixed shaft. A connecting cylinder is fixedly connected to one end of the fixed shaft. A second fixed rod is fixedly connected to the center of one end of the connecting cylinder. A second sliding groove is formed through one side of the second fixed rod. Connecting blocks are symmetrically slidably connected to both ends of the second sliding groove. An insert rod is fixedly connected to one end of each connecting block. One end of each insert rod extends movably through to the outside of the connecting cylinder. A roller is provided at the outer end of each insert rod. Side plates are symmetrically provided on the outer side of one end of the connecting cylinder.

[0007] Furthermore, a one-way screw is rotatably connected inside the first groove. One end of the one-way screw is threadedly connected to the crossbar. A first knob is rotatably connected to one side of the first fixed rod at the position corresponding to the one-way screw. One end of the one-way screw passes through the side wall of the first fixed rod and is fixedly connected to the first knob. One end of the rotating ring is fixedly connected to the movable frame by a first bolt.

[0008] Furthermore, a rack block is fixedly connected to the top of one of the dovetail sliders, and a fixing plate is fixedly connected to one end of the base near the rack block. A rotating shaft is rotatably connected to the inner side of the top of the fixing plate, and a gear is fixedly connected to the end of the rotating shaft. The gear meshes with the rack block. A drive motor is fixedly connected to the outer side of the fixing plate at the position corresponding to the rotating shaft.

[0009] Furthermore, a connecting frame is fixedly connected to one end of the crossbar, and a scraper is fixedly connected to the bottom side of the connecting frame.

[0010] Furthermore, a bidirectional screw is rotatably connected inside the second groove, and the two ends of the bidirectional screw are respectively threaded to the corresponding connecting blocks. A second knob is rotatably connected to one side of the second fixing rod at the position corresponding to the bidirectional screw, and one end of the bidirectional screw passes through the side wall of the second fixing rod and is fixedly connected to the second knob.

[0011] Furthermore, a second bolt is provided at one end of one of the side plates.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this tube threading machine has the following advantages:

[0014] 1. In this solution, a movable frame, dovetail slider, fixed shaft, connecting cylinder, side plate, second bolt, second fixed rod, second slide groove, connecting block, bidirectional screw, second knob, insertion rod, roller, rack block, fixed plate, rotating shaft, and gear are provided. The end of the cable is inserted between two side plates, and the second bolt is tightened. One end of the second bolt passes through the corresponding side plate and abuts against the cable, clamping the cable end between the two side plates. The drive motor runs, driving the rotating shaft and gear to rotate, thereby driving the rack block and the corresponding dovetail slider to move along the dovetail groove, which in turn drives the movable frame, fixed shaft, and connecting cylinder to move horizontally as a whole. This facilitates pulling one end of the cable through the pipe, preventing the cable end from getting tangled inside the pipe, making the operation simple and quick.

[0015] 2. In this solution, a rotating ring, a first fixed rod, a first bolt, a first sliding groove, a one-way screw, a crossbar, a scraper, a first knob, a connecting frame, and a scraper are provided. If there are attached foreign objects on the inner wall of the steel pipe, rotating the first knob will drive the one-way screw to rotate, which in turn will drive the crossbar to move up and down along the first sliding groove. Adjusting the height of the crossbar will allow the scraper to contact the inner wall of the steel pipe. Unscrewing the first bolt allows the rotating ring and the first fixed rod to be manually rotated, causing the scraper to rotate and scrape away the foreign objects at the corresponding position. By repeatedly adjusting the crossbar to the appropriate position, the inner wall of the steel pipe can be scraped around to remove the attached foreign objects. Then, the rotating ring and the first fixed rod are reset, and the first bolt is tightened again to restrict the rotation of the rotating ring. Before inserting the cable, the first knob is rotated again to adjust the position of the crossbar, allowing the connecting frame and scraper to be adjusted to the appropriate position. The scraper can push out the previously scraped impurities and foreign objects in the pipe during the insertion process, preventing blockage of the steel pipe and affecting the subsequent cable insertion operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7As shown, a pipe threading machine is disclosed, comprising a base 1, with a cable 14 wound around one end of the base 1 via a take-up roller, and a movable frame 2 provided at one end of the base 1. Dovetail grooves are formed on both sides of the upper end of the base 1, and dovetail sliders 3 are slidably connected within each dovetail groove. One end of each dovetail slider 3 is fixedly connected to the movable frame 2. A steel pipe 13 is positioned at the upper end of the base 1 between the movable frame 2 and the cable 14. A fixed shaft 4 is fixedly connected to the side of the movable frame 2 near the steel pipe 13. A rotating ring 5 is rotatably connected to one end of the fixed shaft 4, and a first fixed rod 6 is fixedly connected to the outer side of the rotating ring 5. A first sliding groove 8 is formed through one side of the first fixed rod 6. A crossbar 10 is slidably connected to one end of the first slide groove 8. A scraper 11 is fixedly connected to the side of the crossbar 10 away from the fixed shaft 4. A connecting cylinder 15 is fixedly connected to one end of the fixed shaft 4. A second fixed rod 20 is fixedly connected to the center of one end of the connecting cylinder 15. A second slide groove 21 is opened through one side of the second fixed rod 20. Connecting blocks 22 are symmetrically slidably connected to both ends of the second slide groove 21. An insertion rod 25 is fixedly connected to one end of each connecting block 22. One end of each insertion rod 25 extends movably through to the outside of the connecting cylinder 15. A roller 26 is provided at the outer end of each insertion rod 25. Side plates 18 are symmetrically provided on the outer side of one end of the connecting cylinder 15.

[0030] like Figure 1-7 As shown, a one-way screw 9 is rotatably connected inside the first groove 8. One end of the one-way screw 9 is threadedly connected to the crossbar 10. A first knob 12 is rotatably connected to one side of the first fixed rod 6 at the position corresponding to the one-way screw 9. One end of the one-way screw 9 passes through the side wall of the first fixed rod 6 and is fixedly connected to the first knob 12. One end of the rotating ring 5 is fixedly connected to the movable frame 2 by a first bolt 7 to limit the rotation of the rotating ring 5. A connecting frame 16 is fixedly connected to one end of the crossbar 10. A scraper 17 is fixedly connected to the bottom side of the connecting frame 16. The scraper 17 is an arc-shaped plate. If there are attached debris on the inner wall of the steel pipe 13, rotating the first knob 12 will drive the one-way screw 9 to rotate, thereby driving the crossbar 10 along the first groove 8. The slide 8 moves up and down, adjusting the height of the crossbar 10 so that the scraper 11 abuts against the inner wall of the steel pipe 13. The first bolt 7 is unscrewed, and the rotating ring 5 and the first fixed rod 6 can be manually rotated to drive the scraper 11 to rotate and scrape away the foreign objects at the corresponding position. The crossbar 10 is adjusted to a suitable position repeatedly to scrape the inner wall of the steel pipe 13 one revolution. Then the rotating ring 5 and the first fixed rod 6 are reset, and the first bolt 7 is tightened again to restrict the rotation of the rotating ring 5. Before inserting the pipe, the first knob 12 is rotated again to adjust the position of the crossbar 10 so that the connecting frame 16 and the scraper 17 are adjusted to a suitable position. The scraper 17 can push out the impurities and foreign objects scraped in the pipe in the early stage during the pipe insertion process to avoid clogging the steel pipe 13 and affecting the subsequent pipe insertion operation of the cable 14.

[0031] like Figure 1-7As shown, a rack block 27 is fixedly connected to the top of the dovetail slider 3 on one side. A fixing plate 28 is fixedly connected to one end of the base 1 near the rack block 27. A rotating shaft 29 is rotatably connected to the inner side of the top of the fixing plate 28. A gear 30 is fixedly connected to the end of the rotating shaft 29. The gear 30 meshes with the rack block 27. A drive motor 31 is fixedly connected to the outer side of the fixing plate 28 at the position corresponding to the rotating shaft 29. The output end of the drive motor 31 passes through the fixing plate 28 and is fixedly connected to one end of the rotating shaft 29. When the drive motor 31 is started, the rotating shaft 29 and the gear 30 are rotated, which in turn drives the rack block 27 and the corresponding dovetail slider 3 to move along the dovetail groove, which in turn drives the movable frame 2, the fixed shaft 4, and the connecting cylinder 15 to move horizontally as a whole, making it easier to pull one end of the cable 14 through the tube.

[0032] like Figure 1-7 As shown, a bidirectional screw 23 is rotatably connected inside the second slide groove 21. The two ends of the bidirectional screw 23 are threadedly connected to the corresponding connecting blocks 22. A second knob 24 is rotatably connected to one side of the second fixed rod 20 at the position corresponding to the bidirectional screw 23. One end of the bidirectional screw 23 passes through the side wall of the second fixed rod 20 and is fixedly connected to the second knob 24. Rotating the second knob 24 will drive the bidirectional screw 23 to rotate, thereby driving the connecting block 22 and the insertion rod 25 to move in opposite directions. Adjusting the length of the insertion rods 25 at both ends allows the roller 26 to abut against the inner wall of the steel pipe 13, improving stability. A second bolt 19 is provided at one end of one of the side plates 18. The end of the cable 14 is inserted between the two side plates 18. Tightening the second bolt 19 will cause one end of the second bolt 19 to pass through the corresponding side plate 18 and abut against the cable 14, clamping the end of the cable 14 between the two side plates 18.

[0033] Working principle: In use, the initial position of the connecting cylinder 15 and the side plate 18 is at the end of the base 1 away from the cable 14. The steel pipe 13 is placed on the base 1, and the drive motor 31 is started, which drives the rotating shaft 29 and the gear 30 to rotate. This, in turn, drives the rack block 27 and the corresponding dovetail slider 3 to move along the dovetail groove toward the wound cable 14. This, in turn, drives the movable frame 2 to move horizontally, thereby fixing one end of the shaft 4 and the connecting cylinder 15 as a whole, which passes through one end of the steel pipe 13 and then out the other end, clamping the end of the cable 14 into the two side plates. Between the plates 18, tighten the second bolt 19. One end of the second bolt 19 passes through the corresponding side plate 18 and abuts against the cable 14, clamping the end of the cable 14 between the two side plates 18. Rotate the second knob 24, thereby driving the bidirectional screw 23 to rotate, which in turn drives the connecting block 22 and the insert rod 25 to move in opposite directions. Adjust the length of the extended insert rods 25 at both ends so that the roller 26 can abut against the inner wall of the steel pipe 13 to improve stability. Reverse start the drive motor 31, thereby driving the rotating shaft 29 and the gear 30 to rotate in the opposite direction, which in turn drives the gear... The strip 27 and the corresponding dovetail slider 3 move in the opposite direction along the dovetail groove, thereby driving one end of the clamped cable 14 through the steel pipe 13 and out the other end of the steel pipe 13, completing the cable 14 through-pipe operation. If there are attached debris on the inner wall of the steel pipe 13, turn the first knob 12 to drive the one-way screw 9 to rotate, thereby driving the crossbar 10 to move up and down along the first slide groove 8. Adjust the height of the crossbar 10 so that the scraper 11 abuts against the inner wall of the steel pipe 13. Unscrew the first bolt 7, and the rotating ring 5 and the first fixing rod 6 can be manually rotated to drive the cable 14 through the groove. The scraper 11 rotates to remove foreign objects at the corresponding position. By repeatedly adjusting the crossbar 10 to the appropriate position, the inner wall of the steel pipe 13 can be scraped around. Then, the rotating ring 5 and the first fixing rod 6 are reset, and the first bolt 7 is tightened again to restrict the rotation of the rotating ring 5. Before inserting the pipe, the first knob 12 is rotated again to adjust the position of the crossbar 10 so that the connecting frame 16 and the scraper 17 are adjusted to the appropriate position. The scraper 17 can push out the impurities and foreign objects scraped in the pipe in the early stage during the pipe insertion process to avoid clogging the steel pipe 13 and affecting the subsequent pipe insertion operation of the cable 14.
