[0004] The purpose of the utility model is to provide a coiling disc structure for hoisting power supply cables, which can completely solve the deficiencies of the above-mentioned prior art.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A coiling disc structure for hoisting power supply cables includes a left disc body and a right disc body. The middle parts of the opposite surfaces of the left and right disc bodies are provided with outwardly protruding cylindrical bosses. The two bosses are connected by screws. On the end face of one of the bosses, first L-shaped hooks are arranged at intervals on the circumference with the center of the boss end face as the center of the circle. On the end face of the other boss, matching second L-shaped hooks are arranged corresponding to the first L-shaped hooks, and the first L-shaped hooks are clamped with the second L-shaped hooks.

[0007] Further, a positioning rib and a positioning groove are provided on the end face of one of the bosses, and a positioning groove and a positioning rib are correspondingly arranged on the end face of the other boss.

[0008] Further, both the positioning rib and the positioning groove are arc-shaped and are arranged on a circumference with the center of the boss end face as the center of the circle.

[0009] Further, a tooth groove is arranged along the circumference on the edge of the other side of the left disc body or / and the right disc body relative to the boss.

[0010] Further, a driving gear is further included, and the driving gear meshes with the tooth groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The first L-shaped hook is engaged with the second L-shaped hook, so that the left and right disk bodies are limited in the horizontal direction, and the left and right disk bodies are not easily separated. The stress on the screws connecting the left and right disk bodies in the horizontal direction is reduced. Even if the screws become loose, the left and right disk bodies will not be separated.

[0017] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0018] As Figures 1 to 5 shown, a coiling disk structure for hoisting a power cable includes a left disk body 1 and a right disk body 2. Cylindrical convex platforms 3 protruding outward are provided in the middle of the opposite surfaces of the left and right disk bodies 1 and 2. The two convex platforms 3 are connected by four screws. On the end surface of one of the convex platforms 3, first L-shaped hooks 4 are arranged at intervals on a circumference centered on the center of the end surface of the convex platform 3. On the end surface of the other convex platform 3, matching second L-shaped hooks 5 are provided corresponding to the first L-shaped hooks 4, and the first L-shaped hooks 4 are engaged with the second L-shaped hooks 5.

[0019] In this embodiment, positioning convex ribs 6 and positioning grooves 7 are provided on the end surface of one of the convex platforms 3, and positioning grooves 7 and positioning convex ribs 6 are correspondingly arranged on the end surface of the other convex platform 3. Through the cooperation of the positioning convex ribs 6 and the positioning grooves 7, the left and right disk bodies 1 and 2 are more accurately matched, and the assembly is more convenient and time-saving.

[0020] In this embodiment, both the positioning convex ribs 6 and the positioning grooves 7 are arc-shaped and are both arranged on a circumference centered on the center of the end surface of the convex platform 3.

[0021] The utility model utilizes the clamping connection between the first L-shaped hook 4 and the second L-shaped hook 5, so that the left and right discs 1 and 2 are limited in the horizontal direction, the left and right discs 1 and 2 are not easily separated, the stress on the screws connecting the left and right discs 1 and 2 in the horizontal direction is reduced, and even if the screws become loose, the left and right discs 1 and 2 will not be separated.

[0022] In this embodiment, a toothed groove 8 is provided circumferentially along the edge of the other side of the left disc 1 or / and the right disc 2 relative to the boss 3. This embodiment further includes a driving gear 9, and the driving gear 9 meshes with the toothed groove 8.

[0023] In the prior art, the wire reel is directly driven to rotate by a driving motor. The output end of the driving motor is connected to a transmission shaft, and the wire reel is fixedly connected to the transmission shaft. However, in this embodiment, the driving motor drives the driving gear 9 to rotate. Through the meshing of the driving gear 9 and the toothed groove 8, the driving gear 9 drives the wire reel to rotate. By adjusting the different tooth number ratios between the driving gear 9 and the toothed groove 8, different transmission ratios can be achieved.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
