Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary construction, in particular to an electrical wire threading construction device. Background Art

[0002] Building engineering refers to the planning, surveying, design, construction, completion and other technical works for the new construction, reconstruction or expansion of buildings and ancillary structures, as well as the completed engineering entities and the installation works of the supporting lines, pipelines and equipment. Building electricity includes electrical systems such as power supply, lighting, telephone and fire protection. When installing and constructing these electrical systems, cables such as electric wires and signal wires need to be laid. In order to protect the cables and extend their service life, the wires need to be threaded through the pipe. Since the electric wires and cables are relatively soft and it is difficult to pass through the pipe, a wire threading device is needed as a guide to facilitate wire threading.

[0003] The currently used wire threading device usually pushes the electric wire into the pipe by means of a driving component or the like. This method has a good wire threading effect for short or straight pipes. However, when threading a longer or curved pipe, relying only on the driving component to push the electric wire inward from outside the pipe, problems such as bending and blocking of the front end part of the electric wire make it difficult to move forward, and the wire threading effect at this time is relatively poor. In view of this, an electrical wire threading construction device is provided. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electrical wire threading construction device to solve the problems in the above background art.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] An electrical wire threading construction device includes a first base. A first support frame is fixedly connected to the top of the first base. A lower roller is rotatably connected to the top inner surface of the first support frame. A wire conduit is placed inside the first support frame, and the bottom of the wire conduit contacts the surface of the lower roller. A fixed column is fixedly connected to the upper surface of the first base on one side of the first support frame. A threaded rod is rotatably connected to the top of the fixed column. The part of the threaded rod extending out of the top of the fixed column is threadedly connected to a lifting plate. The lifting plate extends above the first support frame and a connecting plate is fixedly connected to the bottom. Upper rollers are rotatably connected to both extended ends of the bottom of the connecting plate. An electromagnet is fixedly installed between the two upper rollers at the bottom of the connecting plate. A second base is provided below one end where the wire conduit extends out of the first base. A support plate is fixedly connected to the upper surface of the second base.

A slot is inwardly opened on the side surface of the metal guiding head. The wire extends into the slot. A groove is opened outside the slot of the metal guiding head. A first screw is provided inside the groove. The first screw penetrates through the inside of the metal guiding head and presses one end of the wire. The electromagnet magnetically attracts the metal guiding head.

[0007] Further, the length of the connecting shaft is longer than that of the winding wheel. The winding wheel is rotatably and slidably connected to the connecting shaft. An adjusting ring is provided on the upper surface of the second base between the winding wheel and the wire conduit. The wire passes through the inside of the adjusting ring.

[0008] Further, a spring is provided between the lifting plate and the connecting plate. The two ends of the spring are respectively fixedly connected to the connecting plate and the spring. A sliding column is fixedly connected to the upper surface of the connecting plate inside the spring. The sliding column extends upwards through the inside of the lifting plate and is slidably connected to the lifting plate.

[0009] Further, a battery compartment is fixedly connected between the side surface of the fixed column and the upper surface of the first base. A battery is fixedly installed inside the battery compartment.

[0010] Further, three universal wheels are fixedly installed on the lower surface of the second base. A support column is fixedly connected to the lower surface of the first base.

[0011] Further, a second support frame is fixedly connected to the upper surface of the second base at the end part of the electric wire.

A second screw penetrates through the inside of the connecting block from the outside and is threadedly connected thereto. A clamping plate is arranged inside the second support frame. A fixing block is fixedly connected to the outer surface of the clamping plate. The second screw extends into the inside of the fixing block and is rotatably connected to the fixing block. The two clamping plates clamp the end of the electric wire.

[0012] The beneficial effects of the present utility model are as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] As Figures 1-5As shown in the figure, an electrical wire threading construction device includes a first base 1. A first support frame 2 is fixedly connected to the top of the first base 1. A lower roller 3 is rotatably connected to the top inner surface of the first support frame 2. A wire conduit 4 is placed inside the first support frame 2. The bottom of the wire conduit 4 contacts the surface of the lower roller 3. A fixed column 5 is fixedly connected to the upper surface of the first base 1 on one side of the first support frame 2. A threaded rod 6 is rotatably connected to the top of the fixed column 5. The part of the threaded rod 6 extending out of the top of the fixed column 5 is threadedly connected to a lifting plate 22. The lifting plate 22 extends above the first support frame 2 and a connecting plate 7 is fixedly connected to its bottom. Upper rollers 8 are rotatably connected to both extended ends of the connecting plate 7 at the bottom and located above the first support frame 2. An electromagnet 9 is fixedly installed between the two upper rollers 8 at the bottom of the connecting plate 7. A second base 10 is provided below one end where the wire conduit 4 extends out and is located on the first base 1. A support plate 11 is fixedly connected to the upper surface of the second base 10. A connecting shaft 12 is fixedly connected between the support plates 11. A winding wheel 13 is sleeved and rotatably connected to the outer surface of the connecting shaft 12. An electric wire 14 is wound around the outer surface of the winding wheel 13. One end of the electric wire 14 extends outwards. A metal guiding head 15 is provided inside the wire conduit 4. A slot 16 is inwardly opened on the side surface of the metal guiding head 15. The electric wire 14 extends into the interior of the slot 16. A groove 17 is opened on the outer side of the metal guiding head 15 at the slot 16. A first screw 18 is provided inside the groove 17. The first screw 18 penetrates through the interior of the metal guiding head 15 and presses one end of the electric wire 14. The electromagnet 9 magnetically attracts the metal guiding head. By first inserting the electric wire 14 into the interior of the slot 16 and screwing on the first screw 18, the first screw 18 presses to fix the end of the electric wire 14. At this time, the threaded rod 6 is rotated to lift the lifting plate 22. Then, the end of the wire conduit 4 is placed on the first support frame 2. Next, the connecting plate 7 is lowered so that the end of the wire conduit 4 is clamped between the upper and lower rollers 3 and the metal guiding head 15 is placed inside the end of the wire conduit 4. At this time, the electromagnet 9 is started to make the electromagnet 9 adsorb the metal guiding head 15. Then, the wire conduit 4 and the second base 10 are pulled backward. At this time, because the metal guiding head 15 is adsorbed by the electromagnet 9, when the wire conduit 4 is twitched, it will rub inside the wire conduit 4 to gradually make the electric wire 14 penetrate into the interior of the wire conduit 4. And when encountering a bend, it can directly pass through the bend by swinging the wire conduit 4 between the first support frames 2, so that the metal guiding head 15 slides normally inside the wire conduit 4. During actual use, by setting the metal guiding head 15 into a bullet shape, its front end can also slide over the surface when passing through relatively uneven places such as the bend of the wire conduit 4, avoiding the front end of the metal guiding head 15 being blocked during sliding. And for the convenience of the staff, a telescopic rod and other structures can be installed on the second base 10 so that the staff can stand and move the second base 10 and the wire conduit 4.

[0022] As Figure 1As shown, in some embodiments, the length of the connecting shaft 12 is longer than that of the winding wheel 13. The winding wheel 13 rotates and is slidably connected to the connecting shaft 12. An adjusting ring 19 is provided between the upper surface of the second base 10 and the wire tube 4 and between the winding wheel 13. The wire 14 passes through the inside of the adjusting ring 19. Specifically, when the winding wheel 13 releases the wire 14, it will be restricted by the adjusting ring 19 so that the winding wheel 13 slides on the surface of the connecting shaft 12, minimizing the bending angle of the wire 14 when the wire 14 is subjected to a tensile force. As a result, the wire 14 is released more easily after being subjected to a tensile force. Moreover, the inner surface of the adjusting ring 19 is provided with rounded corners to reduce the surface wear at the bending point during the release of the wire 14.

[0023] As Figure 3 shown, in some embodiments, a spring 20 is provided between the lifting plate 22 and the connecting plate 7. The two ends of the spring 20 are respectively fixedly connected to the connecting plate 7 and the spring 20. A sliding column 21 is fixedly connected to the upper surface of the connecting plate 7 inside the spring 20. The sliding column 21 extends upward through the inside of the lifting plate 22 and is slidably connected to the lifting plate 22. A clamping column 23 is fixedly connected to a position above the fixed column 5 on the lower surface of the lifting plate 22. A clamping groove 24 is formed on the upper surface of the fixed column 5. The clamping column 23 is clamped inside the clamping groove 24. Specifically, during the downward pressing process, the clamping column 23 is inserted into the clamping groove 24, so that the lifting plate 22 is fixed at two points, thereby preventing structures such as the connecting plate 7 and the lifting plate 22 from rotating around the threaded rod 6 when pulling the wire tube 4; the installed spring 20 and sliding column 21 can contract the spring 20 when the wire tube 4 passes through uneven places such as a turning point, so that it is not necessary to readjust the height of the lifting plate 22 to pass through these places, and the upper roller 8 always fits the outer surface of the wire tube 4.

[0024] As Figure 3 shown, in some embodiments, a battery compartment 25 is fixedly connected between the side surface of the fixed column 5 and the upper surface of the first base 1. A battery 26 is fixedly installed inside the battery compartment 25. Specifically, the installed battery 26 enables the device to work without power, making the device more convenient to use.

[0025] As Figure 1 shown, in some embodiments, three universal wheels 27 are fixedly installed on the lower surface of the second base 10, and a support column 28 is fixedly connected to the lower surface of the first base 1. Specifically, the installed universal wheels 27 make it more convenient for the staff to move the second base 10, and the installed support column 28 can raise the height of the first base 1, making the height of the device parallel and convenient to use.

[0026] As Figure 1 、 5As shown, in some embodiments, a support frame two 29 is fixedly connected to the upper surface of the base two 10 at the end portion of the electric wire 14. The end of the electric wire 14 is located inside the support frame two 29. Connecting blocks 30 are fixedly connected to both sides of the support frame two 29. A second screw 31 penetrates through the inside of the connecting block 30 from the outside and is threadedly connected thereto. A clamping plate 33 is provided inside the support frame two 29. A fixing block 32 is fixedly connected to the outer surface of the clamping plate 33. The second screw 31 extends into the inside of the fixing block 32 and is rotatably connected to the fixing block 32. The end of the electric wire 14 is clamped by the two clamping plates 33 on both sides. Specifically, after the metal guide head 15 is placed into the inside of the wire pipe 4, the end of the wire pipe 4 can be pulled out and fixed between the two clamping plates 33, so that the staff can drive the wire pipe 4 to move together by only moving the base two 10. At the same time, by rotating the second screw 31 to make the clamping plate 33 clamp the wire pipe 4, it can clamp more wire pipes 4 with different sizes within a certain range, improving the practicability of the device.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
