Description

Technical Field

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Direct burial cable is a laying method in which the cable is laid at the bottom of the cable trench after the direct burial cable trench is dug in accordance with the requirements of the specification.

[0003] At present, when the cable is directly buried, it is necessary to wind the cable in a pay-off frame, and then use manual or mechanical arms to pull the cable to the laying position. Finally, the pay-off frame is moved and the wire roller on the pay-off frame is rotated to make the cable fall into the groove and be aligned at the preset position.

[0063] The push plate 42 is connected to the power output shaft of the linear cylinder 41 , and the two are connected by welding or threading, and the push plate 42 is located directly above the discharge port 31 .

[0064] When the linear cylinder 41 drives the push plate 42 to move downward, the push plate 42 is adapted to be inserted into the interior of the material storage box 3 and push one of the fixing cards 9 through the material outlet 31 .

[0067] The first guide rod 321 is arranged inside the storage box 3, and its axial direction is parallel to the front-to-back direction; one end of the first guide rod 321 is fixedly connected to the storage box 3, and the other end thereof is arranged away from the discharge port 31; the surface of the first guide rod 321 is polished to reduce the friction between the fixing card 9 and the top plate 322.

[0092] By adopting the above technical solution, the cable 1000 will shake when it is released, and the expanded diameter portion 621 can protect the cable 1000 from being scratched by the tube opening of the guide tube 62 when it enters the guide tube 62 from the wire roller 2, thereby improving the quality of the cable 1000 when it is laid.

[0093] In some embodiments, please refer to Figures 1 to 4 As a specific implementation of the auxiliary device for direct burial of cables provided in the present application, the transmission mechanism 5 includes a driving gear 51 and a driven gear 52 .
