Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ship cable drum brackets, in particular to a small ship cable drum bracket. Background Art
[0002] The cable drum bracket is used for laying out the cable. Most of the existing drum brackets on ships are heavy symmetrical drum brackets. The symmetrical drum bracket is suitable for installation in places with large spaces, such as the open deck of a ship. When the cable is laid out, the drum is operated. The drum shaft in the cable drum rotates through sliding friction with the drum bracket, thereby achieving the purpose of laying out the cable.
[0003] The symmetrical drum bracket is large and heavy, and difficult to move, so it is applicable to a single environment and cannot meet the needs of complex cable laying environments. In addition, when laying thick cables, due to the heavy weight of the thick cables, the symmetrical drum bracket needs to be equipped with an additional drum brake device to prevent the cable drum shaft from rotating too fast, which leads to high costs, complex tooling, more manpower and high labor intensity. Utility Model Content
[0004] The utility model aims to provide a marine cable drum bracket, which effectively solves the problem that the existing symmetrical drum bracket has a single applicable environment.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A ship cable drum bracket comprises an upper steel plate, a lower steel plate, a seamless steel pipe and a deep groove ball bearing. The upper steel plate and the lower steel plate are both in annular shape. The outer diameter of the upper steel plate is smaller than the outer diameter of the lower steel plate. A first through hole is provided at the center of the upper steel plate, and a second through hole is provided at the center of the lower steel plate.
[0007] The top end of the deep groove ball bearing is welded to the center of the bottom surface of the upper steel plate, the bottom end of the seamless steel pipe is welded to the center of the top surface of the lower steel plate, and the top end of the seamless steel pipe is passed through the center of the deep groove ball bearing and is rotatably connected to the deep groove ball bearing.
[0008] The aperture of the first through hole is smaller than the outer diameter of the deep groove ball bearing, and the aperture of the second through hole is smaller than the outer diameter of the seamless steel pipe.
[0009] The edge of the top surface of the lower steel plate is provided with two handles which are symmetrical with respect to the axis of the seamless steel pipe.
[0010] Furthermore, the central axis of the upper steel plate coincides with the central axis of the lower steel plate.
[0011] Furthermore, the handle is made of round steel, and the handle is welded to the lower steel plate.
[0012] Furthermore, the handle is disposed at an outer side of the orthographic projection of the upper steel plate on the lower steel plate.
[0013] Furthermore, the edge of the lower steel plate is sprayed with a maximum load capacity.
[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The present invention is small in size, light in weight, and easy to move. In addition to being used on the open deck of a ship, it can also be used in narrow spaces such as cabins, effectively coping with the complex cable laying environment in the cabin. The problem that the existing symmetrical roller bracket is large in size and heavy in weight and has a single applicable environment is solved. (2) The present invention is not only simple to manufacture but also has low construction difficulty and is easy to operate, which can effectively save working time and labor costs.

[0020] A marine cable drum bracket, such as Figures 1 to 5 As shown, it includes an upper steel plate 1, a lower steel plate 2, a seamless steel pipe 3 and a deep groove ball bearing 4. The upper steel plate 1 and the lower steel plate 2 are both in annular shape, the outer diameter of the upper steel plate 1 is smaller than the outer diameter of the lower steel plate 2, and the central axis of the upper steel plate 1 coincides with the central axis of the lower steel plate 2. A first through hole 5 is provided at the center of the upper steel plate 1, and a second through hole 6 is provided at the center of the lower steel plate 2. In this embodiment, the outer diameter of the upper steel plate 1 is 500 mm, and the aperture of the first through hole 5 is 200 mm; the outer diameter of the lower steel plate 2 is 600 mm, and the aperture of the second through hole 6 is 40 mm.
[0021] like Figure 1 , Figure 4 and Figure 5As shown, the top end of the deep groove ball bearing 4 is welded to the center of the bottom surface of the upper steel plate 1, the bottom end of the seamless steel pipe 3 is welded to the center of the top surface of the lower steel plate 2, the aperture of the first through hole 5 is smaller than the outer diameter of the deep groove ball bearing 4, and the aperture of the second through hole 6 is smaller than the outer diameter of the seamless steel pipe 3.
[0022] like Figure 1 and Figure 2 As shown, the top end of the seamless steel pipe 3 is passed through the center of the deep groove ball bearing 4 and is rotatably connected to the deep groove ball bearing 4. In this embodiment, the distance between the bottom surface of the upper steel plate 1 and the top surface of the lower steel plate 2 is 185 mm, and the distance between the bottom end of the deep groove ball bearing 4 and the top surface of the lower steel plate 2 is 140 mm.
