Description

Technical Field

[0001] The utility model relates to the field of electromechanical installation, in particular to an adjustable threading auxiliary device for a pre-buried electrical conduit. Background Art

[0002] In existing mechanical and electrical installation projects for housing construction, it is often necessary to carry out threading construction of pre-buried electrical conduits. During the operation, the personnel at the wire delivery end and the personnel at the wire outlet end do not cooperate well, and the wire delivery speed of the wire delivery personnel at the wire delivery end is not synchronized with the wire outlet speed of the wire outlet personnel. During the threading process, it is easy to cause friction between the outer sheath of the cable and the end face of the electrical incoming line, causing the cable to be damaged during the threading construction. Utility Model Content

[0003] The utility model aims to provide an adjustable wire-threading auxiliary device for pre-buried electrical conduits, which is used to solve the problem that during the existing wire-threading construction of pre-buried electrical conduits, the wire-feeding speed of the wire-feeding personnel at the wire-feeding end is not synchronized with the wire-out speed of the wire-out personnel, which easily causes friction between the outer sheath of the cable and the end face of the electrical incoming wire during the wire-threading process, causing the cable to be damaged during the wire-threading construction.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an adjustable wire threading auxiliary device for embedded electrical conduits, comprising:

[0005] The positioning frame is installed at the inlet end of the electrical conduit, and includes two groups of positioning angle plates and two groups of auxiliary rollers. The two groups of positioning angle plates are symmetrically placed and arranged in parallel near the side plates. The two ends of one group of auxiliary rollers are rotatably connected with the two groups of positioning angle plates near the side plates, and the other group of auxiliary rollers is rotatably installed on the corresponding positioning angle plates near the side plates. The two groups of auxiliary rollers form a rectangular wire transmission channel;

[0006] The pre-buried wire box is fixedly mounted on the side plates of the two sets of positioning angle plates where the auxiliary rollers are not mounted by means of fixing parts. The center of the pre-buried wire box is provided with a wire outlet hole, the wire outlet hole is connected with the rectangular wire transmission channel, and the side of the pre-buried wire box is provided with a wire inlet hole;

[0007] One end of the guide steel wire is fixedly connected to one end of the cable and passes through the outlet hole of the pre-buried wire box and the rectangular wire transmission channel.

[0008] As a further solution of the utility model, the fixing member is a fixing bolt, and a plurality of mounting holes are provided on the side panels of the two groups of positioning angle plates where the auxiliary rollers are not installed, and the mounting holes can be used to adapt and install pre-buried wire boxes of corresponding size specifications.

[0009] Compared with the prior art, the utility model designs a positioning frame, a pre-buried wire box and a guide wire. The positioning frame is fixedly installed on the incoming wire end of the electrical conduit through two groups of positioning angle plates. The two groups of auxiliary rollers are installed on the close sides of the two groups of positioning angle plates to form a rectangular wire transmission channel. The pre-buried wire box is fixedly installed on the two groups of positioning angle plates. The cable is introduced from the incoming wire hole of the pre-buried wire box and passes through the outgoing wire hole. The guide wire is introduced from the incoming wire end of the electrical conduit and passes through the outgoing wire end. It is fixedly connected to one end of the cable, and the cable is transported by pulling the guide wire. This solves the problem that during the existing threading construction of the pre-buried electrical conduit, the outer sheath of the cable is easily rubbed against the end face of the electrical incoming wire due to the asynchronous wire feeding speed of the wire feeding personnel at the wire feeding end and the wire outlet speed of the wire outlet personnel, which causes the cable to be damaged during the threading construction.

[0013] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0014] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, a pre-buried electrical conduit adjustable threading auxiliary device includes a positioning frame, which is installed at the inlet end of the electrical conduit, and includes two groups of positioning angle plates 1 and two groups of auxiliary rollers 3. The two groups of positioning angle plates 1 are symmetrically placed, and are arranged in parallel near the side plates. The two ends of one group of auxiliary rollers 3 are rotatably connected with the two groups of positioning angle plates 1 near the side plates, and the other group of auxiliary rollers 3 is rotatably installed on the corresponding positioning angle plates 1 near the side plates, and the two groups of auxiliary rollers 3 form a rectangular wire transmission channel;

[0015] The pre-buried wire box 2 is fixedly mounted on the side plates of the two sets of positioning angle plates 1 where the auxiliary rollers 3 are not mounted, through a fixing piece, and a wire outlet hole 201 is arranged at the center of the pre-buried wire box 2, and the wire outlet hole 201 is connected to the rectangular wire transmission channel, and a wire inlet hole 202 is arranged on the side of the pre-buried wire box 2;

[0016] A guide wire, one end of which is fixedly connected to one end of the cable, and passes through the outlet hole 201 of the pre-buried wire box 2 and the rectangular wire transmission channel;

[0017] In the utility model, the positioning frame is installed at the incoming line end of the electrical conduit, and the rectangular line transmission channel formed by the two groups of auxiliary rollers 3 faces the inside of the electrical conduit. The cable is introduced from the incoming line hole 202 of the embedded wire box 2 and passes through the outgoing line hole 201. At the same time, it is protected by multiple groups of auxiliary rollers 3. At the same time, the guide steel wire is introduced from the incoming line end of the electrical conduit and passes through the outgoing line end. One end of the guide steel wire is fixedly connected to one end of the cable. The cable is transported by pulling the guide steel wire by a person, and the cable does not need to rub against the incoming line port of the electrical conduit.

[0018] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the fixing part is a fixing bolt 4, and a plurality of mounting holes are provided on the side panels of the two groups of positioning angle plates 1 on which the auxiliary rollers 3 are not installed. The mounting holes can be used to adapt to and install the embedded wire boxes 2 of corresponding size specifications. In the utility model, embedded wire boxes 2 of different specifications can be installed using mounting holes of corresponding specifications.

[0019] In summary, the utility model designs a positioning frame, a pre-buried wire box 2 and a guide wire. The positioning frame is fixedly installed on the incoming wire end of the electrical conduit through two groups of positioning angle plates 1. The two groups of auxiliary rollers 3 are installed on the close sides of the two groups of positioning angle plates 1 to form a rectangular wire transmission channel. The pre-buried wire box 2 is fixedly installed on the two groups of positioning angle plates 1. The cable is introduced from the incoming wire hole 202 of the pre-buried wire box 2 and passes through the outgoing wire hole 201. The guide wire is introduced from the incoming wire end of the electrical conduit and passes through the outgoing wire end. It is fixedly connected to one end of the cable, and the cable is transported by pulling the guide wire by a person. This solves the problem that during the existing threading construction of the pre-buried electrical conduit, the outer sheath of the cable is easily rubbed against the end face of the electrical incoming wire due to the asynchronous wire feeding speed of the wire feeding personnel at the wire feeding end and the wire outlet speed of the wire outlet personnel, which causes the cable to be damaged during the threading construction.
