Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and more specifically, to a pipe wire threading device for electric power construction. Background Technique

[0002] With the development of modern building technology, the wiring project of the power system has become increasingly complex. In building construction, in order to ensure the safety and standardization of electric wires and cables, it is usually necessary to pass them through pre-embedded pipes. These pipes may extend over long distances, passing through multiple floors, walls or concrete structures, making the traditional manual wire threading method face many challenges.

[0003] After retrieval, the patent document with the existing publication number CN114336434B provides a wire threading device applicable to building electrical pipes. The device is provided with a wire winding state sensing mechanism mainly composed of an elbow manifold, a first rotating shaft, an elbow manifold lifting spring and a first micro switch in the ventilation chamber. When the strong wire is tightened, the elbow manifold is easily rotated as the strong wire is tightened, and when the strong wire is tightened, it touches the first micro switch in time. In this way, the first micro switch can timely disconnect the power supply line of the wire wheel driving device, stop the operation of the wire wheel driving device, and avoid damage to the wheel driving device. When the strong wire is relaxed, the elbow manifold can automatically return to its original position under the action of the elbow manifold lifting spring, restoring the wire winding state of the wire wheel.

[0004] When the above device blows and releases the wire into the electrical pipe, the strong wire on the wire winding wheel is driven by the flowing air and will quickly enter the pipe without control, easily getting entangled and knotted in the pipe, affecting the passing performance of the strong wire in the pipe and resulting in the inability to smoothly complete the pipe wire threading construction. In view of this, we propose a pipe wire threading device for electric power construction. Summary of the Invention

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] See also Figure 1 and Figure 2, The present invention provides a pipeline wire threading device for electric power construction, which includes a blower 1, a wire box 2, and a connecting pipe 3; the output end of the blower 1 is communicated with one end of the connecting pipe 3, the wire box 2 is fixedly installed at the bottom of the connecting pipe 3 and is communicated with the connecting pipe 3, a wire wheel 4 is arranged in the wire box 2, a rotating shaft 401 is fixedly connected to the middle of the wire wheel 4, the rotating shaft 401 is rotationally connected to the wire box 2 in a damped manner, a traction wire 5 is wound around the wire wheel 4, the traction wire 5 enters the connecting pipe 3 from the wire box 2 and extends out of the connecting pipe 3, and a traction block 6 is fixedly connected to the end of the traction wire 5, and the traction block 6 can be set as a spherical shape.

[0036] When threading a pipeline, first place the traction block 6 into the pipeline, then connect the connecting pipe 3 to the end of the pipeline, and blow air into the connecting pipe 3 through the blower 1 to push the traction block 6 to move towards the other end of the pipeline. The traction block 6 can pull the traction wire 5 that falls off the wire wheel 4; when the traction block 6 moves to the other end of the pipeline, tie the traction wire 5 to the end of the wire, and by pulling the traction wire 5, the wire can pass through the pipeline.

[0037] As Figure 3 Shown in Figure 4 , a hanging ring 301 is fixedly connected to the top of the inner wall of the connecting pipe 3, the traction wire 5 passes through the hanging ring 301 to keep the traction wire 5 in a suspended state. A first driving motor 7 is fixedly installed in the wire box 2, a connecting rod 8 is horizontally slidably connected in the wire box 2, the first driving motor 7 is used to drive the connecting rod 8 to reciprocate, a wire releasing transmission module 9 and a tensioning module 10 are installed on the connecting rod 8, the connecting rod 8 drives the rotating shaft 401 to rotate intermittently in a first direction through the wire releasing transmission module 9, and the connecting rod 8 pulls the traction wire 5 through the tensioning module 10 when the rotating shaft 401 stops rotating; a wire winding module 11 is also installed in the wire box 2, and the wire winding module 11 is used to drive the rotating shaft 401 to rotate in a second direction.

[0038] When the first driving motor 7 drives the connecting rod 8 to reciprocate, it can drive the rotating shaft 401 to rotate intermittently through the wire releasing transmission module 9, and intermittently release the traction wire 5 wound on the wire wheel 4, avoiding the situation that the release speed of the traction wire 5 is too fast, resulting in the accumulation and entanglement of the traction wire 5 in the connecting pipe 3, causing the traction wire 5 to get stuck in the pipeline and unable to pass through the pipeline. During the intermittent release of the traction wire 5, the connecting rod 8 can drive the tensioning module 10 to pull the traction wire 5 when the wire wheel 4 stops rotating, so that the traction wire 5 can be kept taut, avoiding the traction wire 5 freely entering the pipeline under the action of flowing air and getting entangled; at the same time, when the traction block 6 is blocked by an obstacle in the pipeline, the traction block 6 can be pulled back to adjust the position of the traction block 6, facilitating the traction block 6 to pass through the obstacle.

[0039] As Figure 5As shown in the figure, a rocker arm 701 is fixedly connected to the output end of the first driving motor 7. A vertical sliding groove 801 is formed in the connecting rod 8, and the end of the rocker arm 701 is limited within the vertical sliding groove 801. When the first driving motor 7 drives the rocker arm 701 to rotate, the rocker arm 701 can drive the connecting rod 8 to reciprocate.

[0040] As Figures 5 to 7 shown in the figure, the wire pay-off transmission module 9 includes a rack 901, a first gear 902, a second gear 903 and a transmission shaft 904; the rack 901 is fixedly connected to the connecting rod 8, the first gear 902 is rotatably installed in the wire box 2, the first gear 902 is meshed with both the rack 901 and the second gear 903, the second gear 903 is installed on the transmission shaft 904 through a one-way bearing, and the second gear 903 is used to drive the transmission shaft 904 to rotate in the first direction; the transmission shaft 904 is rotatably connected to the rotating shaft 401, a pressure plate 905 is slidably connected to the transmission shaft 904, the second gear 903 and the pressure plate 905 are elastically connected through a first elastic element 906, a friction plate 907 is fixedly connected to the rotating shaft 401, and the pressure plate 905 and the friction plate 907 are in frictional transmission. When the connecting rod 8 moves away from the rotating shaft 401, the rack 901 can drive the second gear 903 to rotate in the first direction through the first gear 902, and drive the transmission shaft 904 to rotate in the first direction through the one-way bearing. The transmission shaft 904 can drive the rotating shaft 401 to rotate in the first direction through the pressure plate 905 and the friction plate 907, so as to pay off the towing line 5 on the wire wheel 4, and the towing block 6 can move to the other end of the pipeline. When the connecting rod 8 approaches the rotating shaft 401, the second gear 903 will rotate in the second direction and cannot drive the transmission shaft 904 to rotate, so that the wire wheel 4 will remain stationary under the action of friction; at this time, the tensioning module 10 can pull the towing line 5 in the opposite direction of the movement of the towing block 6, so that the towing line 5 remains taut and adjusts the position of the towing block 6.

[0041] As Figure 5 shown in the figure, the tensioning module 10 includes a support rod 1001, a pulley 1002 and a second elastic element 1003. The pulley 1002 is located above the wire wheel 4, the towing line 5 bypasses the pulley 1002 and enters the connecting pipe 3. The pulley 1002 is installed on the support rod 1001, the support rod 1001 is slidably connected to the connecting rod 8, and the support rod 1001 and the connecting rod 8 are elastically connected through the second elastic element 1003.

[0042] When the connecting rod 8 approaches the rotating shaft 401, the pulley 1002 will pull the towing line 5 to move in the direction away from the movement of the towing block 6; if the towing line 5 is in a slack state, the support rod 1001 will not be able to compress the second elastic element 1003; if the towing line 5 is in a tensioned state, the second elastic element 1003 will be compressed, shortening the stroke of the support rod 1001.

[0043] As Figure 6As shown, the wire taking-up module 11 includes a second drive motor 1101, a cam 1102, an incomplete gear 1103, a third gear 1104, a touch switch 1105 and a controller 1106. The second drive motor 1101 is fixedly installed in the wire box 2. The cam 1102 and the incomplete gear 1103 are fixedly connected to the output end of the second drive motor 1101. The cam 1102 is in contact with the pressure plate 905. Preferably, the outer side of the pressure plate 905 is rotatably connected to a toggle ring 908. The moving ring 908 is abutted against the cam 1102, the incomplete gear 1103 is meshed with the third gear 1104, the third gear 1104 is fixedly mounted on the rotating shaft 401, the touch switch 1105 is located on one side of the support rod 1001, the support rod 1001 is abutted against the touch switch 1105, the touch switch 1105 is fixedly mounted in the wire box 2, the controller 1106 is electrically connected to the touch switch 1105, and the controller 1106 can obtain the working status of the first drive motor 7.

[0044] When the first drive motor 7 drives the wire wheel 4 to release the wire through the wire release transmission module 9, if the traction wire 5 is in a tensioned state, the travel of the support rod 1001 will not be shortened, and it will abut against the touch switch 1105, so that the touch switch 1105 is closed. The controller 1106 can obtain the information that the touch switch 1105 is in a closed state and the first drive motor 7 is in a running state, and control the second drive motor 1101 to rotate a specified number of circles. When the second drive motor 1101 rotates, the cam 1102 can push the pressure plate 905 to separate from the friction plate 907 through the toggle ring 908, so that the rotating shaft 401 is in a free state. When the incomplete gear 1103 is engaged with the third gear 1104, the rotating shaft 401 can be driven to rotate in the second direction, and the traction wire 5 is wound through the wire wheel 4 to keep the traction wire 5 in a tensioned state, so as to prevent the traction wire 5 from being entangled in the pipeline and affecting the pipeline threading work.

[0045] After the traction block 6 moves to the other end of the pipeline, the fan 1 is turned off, the traction line 5 is tied to the conductor, and the second drive motor 1101 drives the wire wheel 4 to rotate in the second direction, the traction line 5 is wound around the wire wheel 4, and the wire is pulled by the traction line 5 to move in the pipeline to complete the pipeline threading work.
