Description

Technical Field

[0001] This utility model relates to the field of electrical construction technology, and in particular to an electrical construction wiring device. Background Technology

[0002] After the conduit is pre-buried, a wire rope pulling strap is first installed inside the conduit. This step involves inserting the wire rope pulling strap into the conduit from one end and pushing it through the conduit until it protrudes from the other end. Then, the protruding end of the wire rope pulling strap is securely connected to the cable. Next, the wire rope pulling strap is pulled in the opposite direction from the initial insertion end, thus smoothly pulling the cable into the conduit and completing the entire cable pulling process.

[0003] For example, a wiring device for building electrical engineering, with publication number CN221929159U, includes a second motor, a first motor, a base plate, a take-up reel, and a switch. The second motor rotates, which in turn drives the second pulley to rotate, thereby driving the take-up reel to rotate, achieving automatic cable winding with high winding efficiency. When wiring is required, one end of the cable wound on the take-up reel is first passed between the first and second guide wheels, and one end of the cable is inserted into the conduit to be wired. A spring is set to push the second guide wheel to squeeze and limit the cable. The first motor rotates, which in turn drives the first guide wheel to rotate, thereby driving the cable to move and realizing the cable winding operation.

[0004] In summary, the following technical problems exist in the existing technology: In the process of using the above-mentioned existing technology and other typical existing technologies, since the wiring is done by conveying cables, the cables inevitably encounter resistance and friction during the conveying process, causing them to bend, which makes the wiring work inconvenient. Therefore, the method of pre-threading steel wire ropes in the pipeline to pull the cables has emerged. However, most of the existing operation methods rely on manual pulling, which is not very efficient. Therefore, we propose an electrical construction wiring device. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1

[0026] Reference Figure 1-2 An electrical construction wiring device includes a base 1, with a winding mechanism mounted on the top of the base 1. The winding mechanism is used to wind up a steel wire rope. The winding mechanism includes a first upright plate 2, a motor 3, a rotating shaft 4, a winding roller 5, and a steel wire rope 7. Two first upright plates 2 are fixed to the top of the base 1. The motor 3 is fixed to one side of one of the first upright plates 2. A rotating shaft 4 is rotatably connected between the two first upright plates 2 through a bearing. The output end of the motor 3 is fixed to the rotating shaft 4. One end of the rotating shaft 4 passes through one of the first upright plates 2 and is fixed to the winding roller 5. The steel wire rope 7 is wound around the outside of the winding roller 5, and one end of the steel wire rope 7 is fixed to the outside of the winding roller 5.

[0027] A feeding mechanism is installed between the base 1 and the rotating shaft 4. The feeding mechanism is used to assist the wire rope 7 in being wound onto the take-up roller 5.

[0028] The feeding mechanism includes a first pulley 6, a second vertical plate 8, a second pulley 9, a central shaft 10, a lead screw nut 12, and a limiting rod 13. The second vertical plates 8 are fixed to both sides of the top of the base 1. The first pulley 6 is fixed to the outer side of the rotating shaft 4. The second pulley 9 is connected to the outer side of the first pulley 6 via a belt. The central shaft 10 is fixed to the inner side of the second pulley 9. The central shaft 10 is rotatably connected to one of the second vertical plates 8. A reciprocating lead screw 11 is rotatably connected between the two second vertical plates 8. One end of the central shaft 10 passes through one of the second vertical plates 8 and is fixed to the reciprocating lead screw 11. The lead screw nut 12 is threaded onto the outer side of the reciprocating lead screw 11. The reciprocating lead screw 11 is a standard product with dimensions of 40×40-800-1500mm. 45#, the lead screw nut 12 is the existing product 2004 nut. Two limit rods 13 are fixed on the top of the lead screw nut 12. The two limit rods 13 are slidably connected to the wire rope 7. When the motor 3 is started, the output end of the motor 3 drives the rotating shaft 4 and the first pulley 6 to rotate, which in turn causes the second pulley 9 to drive the central shaft 10 and the reciprocating lead screw 11 to rotate synchronously. With the cooperation between the lead screw nut 12 and the reciprocating lead screw 11, the lead screw nut 12 drives the limit rods 13 to perform lateral reciprocating motion. At the same time, the working principle of the lead screw nut 12 and the reciprocating lead screw 11 is common and belongs to conventional means or common knowledge. It will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0029] The feeding mechanism also includes a linear frame 14, a connecting rod 15, and a guide wheel 16. A linear frame 14 is fixed between the two second vertical plates 8 and below the reciprocating screw 11. The bottom of the screw nut 12 is fixed with the connecting rod 15, and the bottom of the connecting rod 15 is rotatably connected with the guide wheel 16. The guide wheel 16 is slidably connected to the inner side of the linear frame 14. When the screw nut 12 drives the connecting rod 15 to rotate, the stability of the screw nut 12 during lateral movement can be increased through the cooperation of the linear frame 14 and the guide wheel 16.

[0030] Example 2

[0031] Further optimizations to Example 1, specifically, such as... Figure 3 As shown, a top post 17 is also fixed to the top of the base 1, and a positioning mechanism is assembled on the top of the top post 17.

[0032] The positioning mechanism includes an L-shaped mounting plate 18, a first transmission plate 19, a handle 20, a second transmission plate 21, a movable rod 22, a guide sleeve 23, a positioning block 24, and a locking groove 25. The top of the top column 17 is fixed with the L-shaped mounting plate 18. One end of the top of the L-shaped mounting plate 18 is rotatably connected to the first transmission plate 19 via a pin. One end of the first transmission plate 19 is rotatably connected to the handle 20. The inner side of the handle 20 is clearance-fitted with the first transmission plate 19. One end of the handle 20 is rotatably connected to the second transmission plate 21 via a pin. One end of the second transmission plate 21 is rotatably connected to the movable rod 22 via a pin. The outer side of the movable rod 22 is slidably connected to the guide sleeve 23. The guide sleeve 23 is fixed to the L-shaped mounting plate 18. The other end of the L-shaped mounting plate 18 is fixed with the positioning block 24. One side of the positioning block 24... A locking groove 25 is provided corresponding to the position of the guide sleeve 23. The locking groove 25 is slidably connected to the wire rope 7. After the wire rope 7 is wound up, the handle 20 is pulled upward, causing the handle 20 to pull the first transmission plate 19 to rotate. This causes the handle 20 to push the movable rod 22 to move through the second transmission plate 21 until the movable rod 22 abuts against the inner side of the locking groove 25 along the inner side of the guide sleeve 23. This presses down the wire rope 7 inside the locking groove 25. Because there is frictional damping in the rotational connection between the handle 20 and the second transmission plate 21, and the first transmission plate 19 can increase the resistance of the handle 20 to rotate after rotation, it is necessary to use force to turn the handle 20 to rotate and reset. This makes it difficult for the movable rod 22 to easily move, increasing the fixing effect of the movable rod 22 on the wire rope 7.

[0033] One end of the positioning block 24 is fixed with a mud scraper 26 corresponding to the position of the locking groove 25. The inner side of the mud scraper 26 is in transition with the wire rope 7. By setting the mud scraper 26, the mud stains on the outside of the wire rope 7 after use can be scraped off, increasing the cleanliness of subsequent use.

[0034] In summary:

[0035] This utility model addresses the technical problem of cable threading in existing technologies and other typical prior art. Because cables are threaded through a transmission method, they inevitably encounter resistance and friction during transport, causing bending and making the threading process inconvenient. Therefore, a method of pre-threading steel wire ropes inside the pipeline for cable pulling has been developed. However, most existing methods rely on manual pulling, resulting in low efficiency. The present invention addresses this problem by employing the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0036] During use, when the wire rope 7 needs to be wound up, the motor 3 is started. The output end of the motor 3 drives the rotating shaft 4 and the winding roller 5 to rotate. At the same time, the rotating shaft 4 drives the first pulley 6 to rotate, which in turn causes the second pulley 9 to drive the central shaft 10 and the reciprocating screw 11 to rotate synchronously. Due to the cooperation between the screw nut 12 and the reciprocating screw 11, the screw nut 12 can drive the limit rod 13 to perform lateral reciprocating motion. This causes the limit rod 13 to drive the wire rope 7 to periodically change the position and angle of the winding roller 5 to wind the wire rope 7, so that the wire rope 7 can be evenly wound on the winding roller 5, improving the winding efficiency and winding neatness.

[0037] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0038] 1. Through the structural design of the winding mechanism and the uniform feeding mechanism, this utility model makes it easy for the wire rope 7 to be evenly wound on the outside of the winding roller 5 as the limit rod 13 is driven by the lead screw nut 12. This avoids the wire rope 7 from accumulating and winding in one place during the winding process of the winding roller 5, and at the same time speeds up the work efficiency and improves the efficiency of this device.

[0039] 2. Through the structural design of the positioning mechanism, this utility model enables the device to fix and limit one end of the wire rope 7 after it has been wound up, preventing the wire rope 7 from rewinding. At the same time, the mud scraper 26 can scrape off the mud stains on the outside of the wire rope 7, resulting in good performance.
