Description

Technical Field

[0001] The utility model relates to the technical field of electric wire threading devices, and more specifically, to an electric wire threading device for municipal engineering. Background Art

[0002] Power construction has a significant driving effect on the social economy, while China's economy is developing rapidly and the power supply is relatively tight. In order to meet the needs of national economic and social development, the country needs to accelerate the construction of power. There are many types of power construction, especially for urban electricity use, which is even more inseparable from the use of electricity. In the process of urban municipal construction, the transmission and layout of power is particularly important. The most common way to transmit power is through cables. Cables are usually laid in the passages of municipal buildings to achieve the purpose of beauty and protection of cables.

[0003] The current power threading devices are mostly simple in structure and only use a simple traction wire to pull the cable to complete the threading work. However, the traction wire and the cable are mostly fixed by a clip-on connection, which is prone to slippage during the traction and pulling process, resulting in threading failure. At the same time, during the threading process, the cable directly contacts the threading channel port, which can easily cause friction damage to the cable or cause it to get stuck, affecting the threading work.

[0007] To achieve the above-mentioned purpose, the utility model provides an electric wire threading device for municipal engineering, comprising a frame, a roller movably connected to the frame via a movable shaft, a screw threaded through the top of the frame, one end of the screw movably connected to a recessed frame, the outer side of the recessed frame overlaps the inner wall of the frame, a limiting wheel movably connected to the recessed frame via a movable shaft, a traction wire is clamped between the roller and the limiting wheel, one end of the traction wire is fixedly connected to a connector, one end of the connector is fixedly connected to a threaded part, a plurality of through grooves are provided on the outer side of the threaded part, and a conical threaded cap is threaded on the threaded part.

[0008] When using an electric power threading device for municipal engineering projects according to the present technical solution, one end of the cable can be inserted into the connector and clamped and fixed through the combined action of the connector, threaded part, through-groove and tapered threaded cap, effectively preventing loosening during the threading process. Through the arrangement of the frame, roller and limiting wheel, the inserted cable can be limited during the threading process, allowing it to enter the threading channel smoothly and steadily, thereby preventing the cable from being damaged or stuck at the threading channel port.

[0009] Furthermore, four corners of one side of the frame are fixedly connected with fixing blocks, and one side of the four fixing blocks is fixedly connected with a suction cup.

[0012] Furthermore, the shaft end of the screw is rotatably connected to a shaft sleeve, and one end of the shaft sleeve is fixedly connected to the top of the recessed frame.

[0013] (3) Beneficial effects

[0024] Example:

[0025] The following is combined with Figure 1-3 The utility model is described in further detail.

[0026] See also Figure 1-3 The utility model provides a technical solution: an electric power threading device for municipal engineering, comprising a frame 1, a roller 4 movably connected to the frame 1 through a movable shaft, a screw 5 threaded through the top of the frame 1, one end of the screw 5 movably connected to a recessed frame 6, the outer side of the recessed frame 6 overlaps the inner wall of the frame 1, and a limiting wheel 7 is movably connected to the recessed frame 6 through a movable shaft. Through the arrangement of the frame 1, the roller 4 and the limiting wheel 7, the inserted cable can be limited during the threading process, so that it can enter the threading channel smoothly and stably, thereby avoiding damage to the cable and The phenomenon of getting stuck at the port of the threading channel occurs, and a traction wire 8 is clamped between the drum 4 and the limiting wheel 7. One end of the traction wire 8 is fixedly connected to a connector 9, and one end of the connector 9 is fixedly connected to a threaded part 10. A plurality of through grooves 11 are provided on the outer side of the threaded part 10, and a conical threaded cap 12 is threaded on the threaded part 10. Through the joint action of the connector 9, the threaded part 10, the through grooves 11 and the conical threaded cap 12, one end of the cable can be inserted into the connector 9 and clamped and fixed, which effectively avoids loosening during the threading process.

[0027] Specifically, the four corners of one side of the frame 1 are fixedly connected with fixed blocks 2, one side of the four fixed blocks 2 is fixedly connected with a suction cup 3, and the middle position of the limiting wheel 7 is designed to be arc-shaped.

[0028] By adopting the above technical solution and providing the fixing block 2 and the suction cup 3, the frame 1 can be conveniently adsorbed and fixed on the outside of the threading channel.

[0029] Specifically, a slide groove 13 is provided on both sides of the inner wall of the frame 1, and a slider 14 is slidably connected in the two slide grooves 13. One side of the two sliders 14 is fixedly connected to the two sides of the recessed frame 6 respectively, and the axial end of the screw 5 is rotatably connected to the shaft sleeve, and one end of the shaft sleeve is fixedly connected to the top of the recessed frame 6.

[0031] The working principle of the utility model is as follows: when in use, the screw rod 5 is rotated, and the screw rod 5 drives the limiting wheel 7 to rise through the recessed frame 6, and the traction wire 8 is taken out from the frame 1, so that it passes through the threading channel, and the suction cup 3 on one side of the frame 1 is attached to the outside of the port of the threading channel, and the frame 1 is pressed to make the suction cup 3 adsorbed and fixed on the outside of the port of the threading channel, and the frame 1 is fixed. One end of the connector 9 is passed through the roller 4 and the limiting wheel 7, and the conical threaded cap 12 is removed and the conical threaded cap 12 is sleeved on the outside of the cable. One end is inserted into the connector 9 through the threaded part 10, and the tapered threaded cap 12 is threadedly connected to the threaded part 10. As the tapered threaded cap 12 is tightened, the through slot 11 on the extruded threaded part 10 contracts, clamping the cable on the connector 9. The traction wire 8 pulls the cable into the threading channel, rotates the screw 5, and the screw 5 pushes the recessed frame 6 to fall, so that the limiting wheel 7 overlaps the cable.
