Description

Technical Field

[0001] The present invention relates to the technical field of cable laying devices, and in particular to a photovoltaic power generation cable laying device. Background Art

[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 scenarios, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction and maintenance of the line. Long-distance communication cables are generally laid in direct burial to ensure safe and reliable communication; urban trunk cables (relay and user trunk cables) are generally laid in pipelines to ensure safe and reliable communication, easy installation and replacement, and beautiful appearance. Urban distribution cables can be laid overhead and on the wall. With the development of modern urban construction, they will gradually be replaced by pipeline laying.

[0003] When laying existing cables, the cable coils are placed on the laying device for fixing, which also facilitates the cable to be drawn out from the coils for laying, reducing the difficulty of pulling the cables. For example, Chinese patent announcement No. CN220684292U discloses "a cable laying device", which provides support force for the take-up wheel through a bearing ring, and the opening of the bearing ring is turned toward the guide block by rotating the cutting turntable, thereby releasing the lock of the take-up wheel, and applying a horizontal thrust to push the take-up wheel away from the frame along the guide block. The take-up wheel and the frame are detachably matched, which reduces the difficulty of replacing the take-up wheel;

[0004] However, in actual use, the cable is laid in various occasions, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel, etc., and the required laying heights of the cables are also different. The angle of the cable led out by the traction structure of the laying device is difficult to change and cannot adapt to the needs of different fields, which can easily cause the cable to bend and be damaged during the laying process. At the same time, the traction of the cable will have great resistance during the laying process, which will affect the laying of the cable and easily scratch the surface of the cable.

[0032] In the present invention, a guide assembly 4 is provided to guide the cable for traction, and a guide wheel 6 is used to support the pulled cable. The height of the guide wheel 6 is adjusted by an angle adjustment assembly 5 to change the lead-out angle of the cable, thereby adapting to different laying occasions and improving the applicability of the laying device. A driving mechanism 7 is provided to provide rotational power for the wire reel, thereby reducing the power required to pull out the cable, thereby facilitating the laying of the cable.

[0033] Furthermore, in this embodiment, an installation frame 43 is provided on the guide frame 41, and a limiting wheel 44 is provided in the installation frame 43. The cable 2 is passed between the guide wheel 42 and the limiting wheel 44. The limiting wheel 44 cooperates with the guide wheel 42 to assist in clamping the cable 2, thereby preventing the cable 2 from separating from the groove on the guide wheel 6.

[0034] In this embodiment, a spring 45 is arranged between the guide frame 41 and the mounting frame 43, a guide rod 46 is fixedly arranged on the mounting frame 43, a pulley is fixedly arranged on the guide frame 41, and a slide groove 47 matching the pulley is opened on the mounting frame 1. When the unwinding roller 3 rotates, the position of the cable wound thereon will also change. At this time, the guide frame 41 can move to the corresponding position of the slide groove under the action of the pulley and the slide groove 47, thereby avoiding excessive friction between different layers of the cable and causing wear, and the guide wheel 6 will also change its position accordingly with the movement of the guide frame 41.

At this time, the guide frame 51 can be rotated up and down at will to adjust the angle, and can also be folded to reduce the space required for the laying device, which is convenient for transportation and storage.

[0038] In addition, in the present embodiment, a rotating disk 57 is fixedly provided on one side of the driving ring 56, a force rod 58 is fixedly provided on the rotating disk 57, and a movable groove matching with the force rod 58 is opened on the extension arm 52.
