Description

Technical Field

[0001] The utility model relates to the technical field of cables, and particularly relates to a cable threading machine for building construction. Background Art

[0002] During the construction of a substation, a large amount of cable laying work needs to be carried out during the installation of the power supply equipment of the substation. For the needs of cable protection and power supply safety, the cables are generally threaded inside a cable trench. However, the inside of the cable trench is usually very narrow, making it very difficult for workers to move inside, and the threading efficiency is very low.

[0003] For example, in the patent with the publication number CN218828802U, a cable threading device is proposed. When this patent is used, the H-shaped frame can be moved by using the moving wheels, and it is moved to the position of the cable trench. Then, the adjusting pipe is lowered, and then the guiding wheel is dropped into the cable trench. Next, the wire on the wire winding frame is passed through between the guiding wheel and the traction wheel, and under the action of the traction motor, it can assist in guiding the wire into the trench. However, in this solution, since the radius of some cables is relatively large, and the gap between the guiding wheel and the traction wheel is fixed, it is difficult for the cables with a relatively large radius to enter between the guiding wheel and the traction wheel, so that it is difficult for the guiding wheel and the traction wheel to guide the cables with a relatively large radius, affecting the subsequent cable threading work of the staff.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, a wire threading machine for building construction, including a base plate 1. A support frame 3 is fixedly installed on the top surface of the base plate 1. A communication hole 13 is opened on the top surface of the base plate 1. A wire winding wheel 5 is arranged on the top surface of the base plate 1. A guiding component is arranged on the bottom surface of the base plate 1 for guiding the wire. The guiding component includes two mounting blocks 20. Both of the two mounting blocks 20 are arranged on the bottom surface of the base plate 1. Two supporting blocks 21 are arranged on the bottom surfaces of the two mounting blocks 20. Guide wheels 22 are arranged between the two mounting blocks 20 and the two supporting blocks 21. Positioning grooves 33 are opened on one side of the mounting block 20 and one side of the supporting block 21. Rotating columns 34 are fixedly installed at both ends of the guide wheel 22. The inner circumferential wall surface of the positioning groove 33 is movably sleeved with the outer circumferential wall surface of the rotating column 34. A fixing frame 29 is fixedly installed on one side of the supporting block 21. A mounting plate 25 is movably sleeved inside the fixing frame 29. A circular through hole is opened on one side of the fixing frame 29. A mounting rod 30 is fixedly installed on one side of the mounting plate 25. The outer circumferential wall surface of the mounting rod 30 is movably sleeved with the inner circumferential wall surface of the circular through hole. A first spring 31 is movably sleeved on the outer circumferential wall surface of the mounting rod 30. One end of the first spring 31 is fixedly connected to one end of the mounting rod 30. The other end of the first spring 31 is fixedly connected to one side of the fixing frame 29. A connecting frame 24 is fixedly installed on one side of the mounting block 20. The mounting plate 25 is movably sleeved with the connecting frame 24. Two clamping columns 27 are fixedly installed on one side of the mounting plate 25. A number of clamping holes 26 are opened on one side of the connecting frame 24. The outer circumferential wall surface of the clamping column 27 is movably sleeved with the inner circumferential wall surface of the clamping hole 26. A limiting hole 6 is opened on one side of the connecting frame 24. Two support rods 32 are fixedly installed inside the limiting hole 6. A placing block 28 is movably sleeved inside the limiting hole 6. Two placing holes 36 are opened on the top surface of the placing block 28. The outer circumferential wall surface of the placing hole 36 is movably sleeved with the inner circumferential wall surface of the support rod 32. An installation groove 23 is opened on one side of the placing block 28. A second spring 35 is fixedly installed inside the installation groove 23. One end of the second spring 35 is fixedly connected to one end of the mounting plate 25. By setting the guide wheels 22, before guiding the wire with the two guide wheels 22, the staff needs to adjust the gap between the two guide wheels 22 according to the radius of the wire. The staff squeezes the two mounting rods 30, making the mounting rods 30 move inward inside the circular through hole of the fixing frame 29 and at the same time compressing the first spring 31. The inward movement of the mounting rods 30 also makes the mounting plate 25 move inward. The inward movement of the mounting plate 25 drives the clamping columns 27 to move inward and at the same time stretches the second spring 35 inside the installation groove 23 of the placing block 28. The staff moves the clamping columns 27 into the clamping holes 26 on the connecting frame 24 by squeezing the two mounting rods 30. Losing the restriction of the clamping columns 27, the staff moves the mounting rods 30 downward to drive the mounting plate 25 and the guide wheels 22 between the two supporting blocks 21 to move downward. The downward movement of the mounting plate 25 also drives the second spring 35 to move downward.The second spring 35 moves downward to place the placing block 28 to move downward inside the limiting hole 6 on the connecting frame 24 along the support rod 32. The worker moves the guide wheel 22 between the two support blocks 21 downward to a proper position according to the radius of the cable. The worker loosens the mounting rod 30, and the acting forces of the first spring 31 and the second spring 35 cause the mounting plate 25 to move outward. The outward movement of the mounting plate 25 drives the clamping column 27 to move outward and enter the inside of the clamping hole 26 on the connecting frame 24, thereby determining the gap between the two guide wheels 22. After the guide wheel 22 between the two support blocks 21 moves downward, the gap between the two groups of guide wheels 22 increases, and at the same time, the two guide wheels 22 can guide the cable with a larger radius. The worker places the cable on the winding wheel 5 into the two guide wheels 22 through the communication hole 13 on the substrate 1. The worker pulls the cable between the two guide wheels 22 and at the same time makes the guide wheel 22 drive the rotating column 34 to rotate inside the positioning grooves 33 on the mounting block 20 and the support block 21, so that the two guide wheels 22 can guide the cable with a larger radius, achieving the guiding effect on the cable, avoiding the difficulty of guiding the cable with a larger radius due to the fixed gap between the two guide wheels 22, and facilitating the worker to thread the cable.

The connecting plate 18 is movably sleeved with the connecting hole 19. The top surface of the mounting block 20 is fixedly connected to the bottom surface of the connecting plate 18. A movable hole 11 is formed on the top surface of the support frame 3. A lead screw 15 is movably sleeved on the inner wall surface of the movable hole 11. A hand wheel 12 is fixedly installed on the top surface of the lead screw 15. A circular through hole is formed on the top surface of the movable plate 10.

By providing the hand wheel 12, when the staff rotates the hand wheel 12, it drives the lead screw 15 to rotate and at the same time makes the lead screw 15 rotate inside the movable hole 11 of the support frame 3. The rotation of the lead screw 15 also makes the movable plate 10 move downward along the lead screw 15. The downward movement of the movable plate 10 drives the connecting plate 18 to move downward inside the connecting hole 19 of the base plate 1. The downward movement of the connecting plate 18 also makes the mounting block 20, the support block 21 and the guide wheel 22 move downward, thereby adjusting the height of the two guide wheels 22. Limiting holes 16 are formed on both sides of the support frame 3. Limiting blocks 17 are fixedly installed on both sides of the movable plate 10. The limiting blocks 17 are movably sleeved with the limiting holes 16. By providing the movable plate 10, when the movable plate 10 moves downward, it drives the limiting blocks 17 to move downward inside the limiting holes 16 of the support frame 3. The limiting blocks 17 can limit the movement of the movable plate 10, achieving the limiting effect on the movable plate 10.

[0026] Embodiment III

[0027] Based on the above Embodiment 1 or 2, refer to Figure 1 , Figure 2 and Figure 3 , a support hole 9 is formed on the top surface of the base plate 1. A second bearing 14 is fixedly sleeved on the inner wall surface of the support hole 9. The outer wall surface of the lead screw 15 is fixedly sleeved with the inner wall surface of the inner ring of the second bearing 14. By providing the lead screw 15, the rotation of the lead screw 15 drives the inner ring of the second bearing 14 to rotate. The second bearing 14 can support the lead screw 15, achieving the support effect on the lead screw 15. Two support plates 2 are fixedly installed on the top surface of the base plate 1. A circular through hole is formed on one side of the support plate 2. A first bearing 7 is fixedly sleeved on the inner wall surface of the circular through hole. Connecting rollers 8 are fixedly installed at both ends of the wire winding wheel 5. The outer wall surface of the connecting roller 8 is fixedly sleeved with the inner wall surface of the inner ring of the first bearing 7. By providing the wire winding wheel 5, the staff can store the cable on the wire winding wheel 5. When the staff uses the cable on the wire winding wheel 5, the staff pulls the cable, making the wire winding wheel 5 drive the connecting roller 8 and the inner ring of the first bearing 7 to rotate, thereby releasing the cable on the wire winding wheel 5. A plurality of support legs 4 are fixedly installed on the bottom surface of the base plate 1. Self-locking universal wheels are fixedly installed on the bottom surface of the support legs 4.

[0028] Working principle: Please refer to Figures 1 - 6As shown in the figure, through the provided guide wheels 22, before guiding the cable using the two guide wheels 22, the staff needs to adjust the gap between the two guide wheels 22 according to the cable radius. The staff squeezes the two mounting rods 30, causing the mounting rods 30 to move inward within the circular through-holes of the fixed frame 29 while compressing the first spring 31. The inward movement of the mounting rods 30 also causes the mounting plate 25 to move inward. The inward movement of the mounting plate 25 drives the clamping post 27 to move inward while stretching the second spring 35 inside the mounting groove 23 of the placing block 28. The staff moves the clamping post 27 into the clamping hole 26 on the connecting frame 24 by squeezing the two mounting rods 30. Losing the restriction of the clamping post 27, the staff moves the mounting rod 30 downward, driving the mounting plate 25 and the guide wheel 22 between the two support blocks 21 downward. The downward movement of the mounting plate 25 also causes the second spring 35 to move downward. The downward movement of the second spring 35 allows the placing block 28 to move downward along the support rod 32 inside the limiting hole 6 on the connecting frame 24. The staff moves the guide wheel 22 between the two support blocks 21 downward to a suitable position according to the cable radius. The staff releases the mounting rod 30, and the acting forces of the first spring 31 and the second spring 35 cause the mounting plate 25 to move outward. The outward movement of the mounting plate 25 drives the clamping post 27 to move outward into the clamping hole 26 on the connecting frame 24, thereby determining the gap between the two guide wheels 22. After the guide wheel 22 between the two support blocks 21 moves downward, the gap between the two sets of guide wheels 22 increases, and at the same time, the two guide wheels 22 can guide the cable with a larger radius. The staff places the cable on the winding wheel 5 through the communication hole 13 on the substrate 1 between the two guide wheels 22. The staff pulls the cable between the two guide wheels 22 while causing the guide wheel 22 to drive the rotating column 34 to rotate inside the positioning grooves 33 on the mounting block 20 and the support block 21, so that the two guide wheels 22 can guide the cable with a larger radius, achieving the guiding effect on the cable, avoiding the difficulty of guiding the cable with a larger radius due to the fixed gap between the two guide wheels 22, and facilitating the staff to thread the cable.

[0029] Through the provided handwheel 12, the staff rotates the handwheel 12 to drive the lead screw 15 to rotate while causing the lead screw 15 to rotate inside the movable hole 11 of the support frame 3. The rotation of the lead screw 15 also causes the movable plate 10 to move downward along the lead screw 15. The downward movement of the movable plate 10 drives the connecting plate 18 to move downward inside the connecting hole 19 on the substrate 1. The downward movement of the connecting plate 18 also causes the mounting block 20, the support block 21, and the guide wheel 22 to move downward, thereby adjusting the height of the two guide wheels 22. Through the provided winding wheel 5, the staff can store the cable on the winding wheel 5. When the staff uses the cable on the winding wheel 5, the staff pulls the cable, causing the winding wheel 5 to drive the connecting roller 8 and the inner ring of the first bearing 7 to rotate, thereby releasing the cable on the winding wheel 5.
