Description

Technical Field

[0001] This utility model belongs to the field of electrical technology in building construction, and specifically relates to a wiring device for building electrical construction. Background Technology

[0002] In building electrical construction, wiring is a fundamental and crucial task. Its purpose is to pass wires, cables, and other conductors through pre-laid conduits to achieve the connection and layout of electrical circuits. For a long time, electrical workers have relied primarily on traditional manual wiring methods, using wires or steel wires as guides to manually push and pull the wires through the conduits. However, this traditional method has many problems in practical application, seriously affecting construction efficiency and quality.

[0003] Existing manual threading methods require workers to continuously push and pull the guide tool and wire, especially when threading through long-distance, winding pipes, where the labor intensity increases exponentially. Prolonged high-intensity work easily leads to worker fatigue, reducing work efficiency and potentially causing physical discomfort or even occupational diseases such as arm pain and lumbar disc herniation. During manual threading, the wire is easily subjected to external pulling and twisting. Due to the greater arbitrariness of manual operation, problems such as insulation damage and wire core deformation can occur, affecting the electrical performance and lifespan of the wire. Workers need to directly contact the guide tool and wire during manual threading, increasing the risk of electric shock, cuts, and other safety accidents. These safety hazards are particularly prominent in damp and confined construction environments. When using metal guide tools such as iron or steel wire, improper operation can damage the inner wall of the pipe, affecting its lifespan and the insulation performance of the electrical system. Therefore, solving these technical problems is a pressing issue that needs to be addressed. Utility Model Content

[0004] This utility model provides a wire threader for building electrical construction, which adopts a handheld operating box design. The upper and lower push wheels are driven by a motor to clamp and transport the wire forward. Compared with manual wire threading, it eliminates the need for workers to continuously push and pull the guide tool and wire, effectively reducing the labor intensity of workers, avoiding fatigue caused by long-term high-intensity work, thereby improving work efficiency and shortening the construction period.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A wiring harness for building electrical construction includes an operation box. A horizontally arranged wiring channel is provided on the front side of the operation box. An upper operation slot is provided on the upper side of the wiring channel, and a lower operation slot is provided on the lower side of the wiring channel, with the upper and lower operation slots corresponding vertically. A first motor is provided on the rear side of the operation box. The main shaft of the first motor extends forward out of the upper operation slot, and an upper push wheel is fixed on the main shaft of the first motor. A second motor is provided below the first motor. The main shaft of the second motor extends forward out of the lower operation slot, and a lower push wheel is fixed on the main shaft of the second motor.

[0007] Both the upper and lower push wheels are rubber wheels, and they are fixed together by bolts.

[0008] The upper and lower operating slots have several threaded mounting holes on their side walls. Cleaning bolts are fixed in the threaded mounting holes, and a cleaning cloth or cleaning sponge is provided at the rear end of the cleaning bolts.

[0009] The control box is equipped with hand levers on both the top and bottom sides.

[0010] Both ends of the wiring channel of the operation box are provided with internal threads, and auxiliary limiting cleaning tubes are connected to both ends of the wiring channel respectively. The auxiliary limiting cleaning tubes are provided with brushes inside.

[0011] The first and second motors are powered by external wiring or batteries; the battery compartment is located on the control box.

[0012] The control boxes at both ends of the threading channel are equipped with lights.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows: The wire threader adopts a handheld operation box design. After the wire to be threaded is clamped by the upper and lower push wheels through the threading channel, the threading channel is aligned with the threading pipe, the motor switch is turned on, and the first motor and the second motor move simultaneously to clamp the wire and convey it forward. Compared with manual threading, it has the technical characteristics of stable wire feeding speed and stable wire feeding force, and solves the technical problem that manual threading is prone to fatigue of workers due to long-term high-intensity operation, resulting in reduced work efficiency.

[0014] The wire is held and transported by the upper and lower push wheels of the rubber structure, which prevents the wire from being pulled or twisted by external forces, thus avoiding technical problems such as insulation damage and core deformation.

[0015] Compared to existing manual wiring methods where workers need to directly contact the guiding tools and wires, this invention eliminates the need for workers to touch the wires during the initial manual operation when the wire is clamped by the upper and lower push wheels. This avoids safety accidents such as electric shock and scratches. When using the wire puller, the wire ends are wrapped with insulating tape, which protects both the wire ends and the conduit from being scratched by the wire ends. The invention also eliminates the need for auxiliary tools such as iron or steel wire, thus avoiding damage to the inner wall of the conduit and preventing impacts on the conduit's lifespan and the insulation performance of the electrical system.

Different specifications of the upper push wheel 6 and lower push wheel 8 can be quickly replaced according to the thickness of the wire, meeting the clamping and conveying needs of wires of varying thicknesses.

[0027] The upper operating groove 3 and the lower operating groove 4 are provided with several threaded mounting holes on their side walls. Cleaning bolts are fixed in the threaded mounting holes.

[0031] Lighting lamps 13 are provided on the operation boxes 1 at both ends of the wiring channel 2. Example

[0032] The operation box 1 has hand-held levers 10 on its upper and lower sides for easy hand operation by staff. The first motor 5 and the second motor 7 can be powered by external wiring or batteries. The battery compartment 12 is located on the operation box 1, providing flexible power supply options for the motors to adapt to different construction environments. The operation box 1 serves as the main frame of the entire wire threader, with a horizontally positioned wire threading channel 2 on its front side for the passage of the wire to be threaded. The upper side of the wire threading channel 2 has an upper operating groove 3, and the lower side has a lower operating groove 4. These grooves are positioned vertically to provide space for motor installation and the operation of the push wheel.

[0033] A first motor 5 and a second motor 7 are installed on the rear side of the control box 1. The main shaft of the first motor 5 extends forward into an upper operating groove 3, and an upper push wheel 6 is fixed on its main shaft.
