Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.

Example 1:

referring to fig. 1-4, a cabling aid includes a cable guide unit and a retractable member;

The cable guiding unit comprises a fixed bracket and a cable guiding wheel 1;

the cable guide wheel 1 is arranged on the fixed bracket;

The telescopic component comprises a threaded rod 2, a fixed plate 3, a fastener and a locking piece 4; one end of the threaded rod 2 is fixedly connected with the fixed plate 3; the other end of the threaded rod 2 is connected with the fixed support, and the locking piece 4 (specifically, a nut) is sleeved on the threaded rod 2 and is tightly attached to the fixed support, so that the connection stability is convenient to increase.

The fixed bracket comprises a supporting tube 5, a first frame and a second frame which are oppositely arranged; the two ends of the supporting tube 5 are respectively connected with the first frame and the second frame through first fasteners (specifically circular tube fasteners), and the ends of the two ends extend to the outside of the first frame and the second frame, so that the threaded rod 2 can be conveniently connected; specifically, one end of the threaded rod 2 far away from the fixed plate 3 is inserted into the support tube 5, and the locking piece 4 is screwed until the locking piece 4 is tightly attached to the support tube 5, and the fixed plate 3 is tightly attached to the inner wall of the corner cable well, so that the locking connection effect between the telescopic component and the support tube 5 is achieved;

the cable guide wheel 1 is fixedly arranged on the supporting tube 5, and the cable guide wheel and the supporting tube are arranged along the same central axis;

the end part of the first frame, the end part of the second frame and the end part of the supporting tube 5 are connected with the inner wall of the corner cable well through the telescopic parts, so that the stability of the fixing support during operation can be improved.

The first frame is a groined frame formed by four connecting pipes 6 through second fasteners (in particular circular pipe fasteners); the second frame has the same structure as the first frame. The first frame and the second frame adopt a groined frame so as to be convenient for connecting the threaded rod 2; specifically, the threaded rod 2 is far away from the one end of the fixed plate 3 and inserts the connecting pipe 6, and through twisting the retaining member 4 to the retaining member 4 hugs closely on the connecting pipe 6, and the fixed plate 3 hugs closely on the inner wall of the corner cable well, thereby reach scalable part with locking connection effect between the fixed support.

The number of the supporting tubes 5 is four, and the supporting tubes are correspondingly arranged on four corners of the first frame and the second frame; the number of the cable guide wheels 1 is determined according to the cable laying requirement, and the number of the cable guide wheels is generally two, and the cable guide wheels are respectively arranged on two supporting tubes 5 arranged along the diagonal line, so that the guiding effect is effectively provided.

Referring to fig. 4, the operation process of the cable laying auxiliary device when laying cables is as follows:

firstly, according to the size of a corner cable well, initially positioning the space structure of the fixed support, and installing a cable guide wheel 1, namely connecting and fixing a connecting pipe 6 with a proper length into a first frame and a second frame (the first frame and the second frame are correspondingly arranged up and down) through a second fastener; after the cable guide wheel 1 is sleeved on the support tube 5 with proper length, two ends of the support tube 5 are connected to the first frame and the second frame through first fasteners;

secondly, 20 groups of telescopic components are selected, wherein 8 groups of telescopic components are arranged between the first frame and the vertical inner wall of the corner cable well and are used for connecting the first frame and the vertical inner wall of the corner cable well; a further 8 sets of said telescoping members mounted between said second frame and the vertical inner wall of said corner cable well for connecting the two; the last 4 groups of telescopic components are arranged between the four supporting pipes 5 and the bottom inner wall of the corner cable shaft and are used for connecting the four supporting pipes 5 and the bottom inner wall of the corner cable shaft;
