[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0025] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0027] like Figure 1-3 A subway section cable laying mechanical arm shown includes: a column 1 and a cable rack 2. The column 1 is fixed on a rail trolley, and the cable rack 2 is hinged on the column 1. As the rail trolley moves, the cable rack 2 moves along the tunnel, thereby laying cables along the line. A first hydraulic component 3 is provided between the column 1 and the cable rack 2. The first hydraulic component 3 is used to control the angle between the cable rack 2 and the column 1, that is, to change the height of the end of the cable rack 2. The height adjustment facilitates the installation of cables corresponding to different positions. In order to facilitate the installation of the first hydraulic component 3, the cable rack 2 is preferably hinged at the top of the column 1.

[0028] The first hydraulic assembly 3 has a limited range of height values ​​that can be changed at the end of the cable rack 2. To further increase the range of change, in one embodiment, the present solution is designed with a second hydraulic assembly 4: the column 1 includes an upper column and a lower column, the first hydraulic assembly 3 is connected to the upper column, and a second hydraulic assembly 4 that changes the distance between the upper column and the lower column is provided between the upper column and the lower column. The second hydraulic assembly 4 changes the height of the column 1, that is, changes the height value of the near end of the cable rack 2, and thus changes the height value of the far end of the cable rack 2.

[0029] The cable rack 2 is a frame structure, and the cable passes through the hollow interior from the near end and is pulled out from the far end. In order to facilitate traction and avoid scratching, guide members are provided at both ends of the cable rack 2 to guide the cable to move inside.

[0030] In one embodiment, the guide member is a guide roller 5, and multiple groups of guide rollers 5 are provided at each end, which are spliced ​​to form a polygon. The cable moves on the polygonal guide roller 5, and multiple cables can be laid at the same time. Specifically, the cross section of the cable rack 2 is a polygon, and each side corresponds to a guide roller 5. Optionally, the cross section of the cable rack 2 is a triangle, a rectangle, or a pentagon. The guide roller 5 is made of rubber.

[0031] The function is realized in the following way: the base is fixed on the flat plate of the rail car, one or more cables are passed through the inside of the pay-off arm, a rubber guide roller 5 is arranged inside the pay-off arm, and the rail car moves forward at a uniform speed, thereby driving the cable laying.

[0032] The first hydraulic assembly 3 and the second hydraulic assembly 4 together form a universal joint structure of the cable rack 2, which can operate the cable arm to lay cables at different heights and angles. During the laying process, the operator only needs to hold the pay-off arm by hand to align the cable through the cable arm with the bracket to achieve cable laying.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
