Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to an auxiliary device for cable laying. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. This is a common construction link in industries such as electricity, communication, and transportation, and is crucial for ensuring the stable transmission of electricity or signals. Cable laying involves multiple aspects, including route planning, preparation of tools and equipment, construction operations, and subsequent testing and maintenance.

[0003] In the prior art, when laying cables, a tractor is used to tow the cables. However, the moving cables lack support and will be directly dragged on the ground, and the cables will directly rub against the ground. Especially when the ground is uneven or there are sharp objects, the outer sheath of the cables is easily worn or even damaged, which will affect the insulation performance and overall quality of the cables. Long-term wear may also cause damage to the internal structure of the cables, shortening the service life of the cables. In addition, when the cables are dragged on the ground, they are easily affected by factors such as terrain and obstacles, resulting in an unsmooth laying process, increasing the difficulty and time cost of laying.

[0004] Therefore, it is necessary to design an auxiliary device for cable laying to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an auxiliary device for cable laying.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0022] A spring has one end connected to the fixing frame and the other end connected to the collar;

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0037] Referring to Figures 1-4 , an auxiliary device for cable laying includes a fixing frame 1; two wheel frames 2, both slidably arranged on the fixing frame 1; two limit wheels 3, respectively rotatably installed on the two wheel frames 2; two guide blocks 4, respectively fixed on the two wheel frames 2; two guide rods 5, both fixed on the fixing frame 1, and the two guide blocks 4 are respectively slidably sleeved on the two guide rods 5. During the movement of the wheel frame 2, the guide blocks 4 and the guide rods 5 play a role in limiting the movement of the wheel frame 2, ensuring the stability of the movement of the wheel frame 2. The staff places the fixing frame 1 on the cable conveying path, passes the cable through the two limit wheels 3, and by adjusting the positions of the two limit wheels 3, makes the two limit wheels 3 both contact the cable, and uses the two limit wheels 3 to provide limitation for the cable. Under the action of the two limit wheels 3, the cable can be separated from the ground, avoiding the situation where the cable is dragged on the ground;

[0038] The cable laying auxiliary device further includes two sliding structures, both of which are arranged on the fixing frame 1. The two sliding structures are respectively connected to the two wheel frames 2. The sliding structure includes: a sliding rod 61, which passes through the fixing frame 1 and is slidably connected to the fixing frame 1. One end of the sliding rod 61 is fixedly connected to the wheel frame 2; a plurality of card slots 62 are all opened on the sliding rod 61, and the plurality of card slots 62 located on the same sliding rod 61 are arranged in a linear array.

[0039] The cable laying auxiliary device further includes two positioning structures, both of which are arranged on the fixing frame 1. The positioning structure includes: an opening 71 opened on the fixing frame 1; a positioning rod 72 slidably arranged in the opening 71, and the inner surface of the opening 71 is in mutual fit with the outer surface of the positioning rod 72; a collar 73 fixedly sleeved on the positioning rod 72; a spring 74, one end of which is connected to the fixing frame 1 and the other end of which is connected to the collar 73; a positioning block 75 fixed at the bottom end of the positioning rod 72 and extending into one of the card slots 62. The shape of the positioning block 75 is adapted to the shape of the card slot 62. When the two limiting wheels 3 jointly clamp the cable, the staff loosens the positioning rod 72, so that the positioning rod 72 is reset under the action of the spring 74. When the positioning rod 72 moves downward, it will drive the positioning block 75 to move downward. Further, the staff can fine-tune the position of the sliding rod 61 by pulling the sliding rod 61, so that the positioning block 75 is inserted into the corresponding card slot 62. At this time, the positioning block 75 fixes the position of the sliding rod 61, and the position of the limiting wheel 3 will also be fixed. This adjustment method is fast and convenient.

[0040] The specific working principle of the present utility model is as follows:

[0041] When the cable laying auxiliary device proposed by the present utility model is in use, the staff places the fixing frame 1 on the cable conveying path, passes the cable through the two limiting wheels 3, and by adjusting the positions of the two limiting wheels 3, makes both of the two limiting wheels 3 contact the cable, and uses the two limiting wheels 3 to provide limitation for the cable. Under the action of the two limiting wheels 3, the cable can be separated from the ground, avoiding the situation that the cable is dragged on the ground.

[0042] When adjusting the position of the limit wheel 3, the staff first pull up the positioning rod 72. When the positioning rod 72 moves upward, it can drive the positioning block 75 to move upward, so that the positioning block 75 disengages from the corresponding card slot 62. Without the restriction of the positioning block 75, the sliding rod 61 can slide freely on the fixed frame 1. At this time, the staff can adjust the positions of the wheel frame 2 and the limit wheel 3 by pushing or pulling the sliding rod 61. When the two limit wheels 3 clamp the cable together, the staff release the positioning rod 72, so that the positioning rod 72 resets under the action of the spring 74. When the positioning rod 72 moves downward, it will drive the positioning block 75 to move downward. Further, the staff can fine-tune the position of the sliding rod 61 by pulling the sliding rod 61, so that the positioning block 75 is inserted into the opposite card slot 62. At this time, the positioning block 75 fixes the position of the sliding rod 61, and the position of the limit wheel 3 will also be fixed. This adjustment method is fast and convenient.

[0043] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
