Description

Technical Field

[0001] The utility model belongs to the field of braking, and particularly relates to a braking device for a cable trolley. Background Art

[0002] The single-track hoist trolley in coal mines is a special equipment for transporting various rubber hoses in fully mechanized coal mining faces. The braking mechanism of the mine cable trolley is one of the main components of the single-track hoist trolley in coal mines.

[0003] As the fully mechanized coal mining face moves forward, cables, emulsion pump stations, water pipes, etc. that are matched with the working face need to move synchronously. Since there is no special moving equipment for cables, emulsion hoses, water pipes, etc., there are certain difficulties in transportation at this time. Therefore, trolleys are used, and the trolleys need to be equipped with braking equipment. At present, the braking equipment of trolleys has a complex structure, high manufacturing cost, and relatively large weight. This application provides a braking device for a cable trolley. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a braking device for a cable trolley to solve the problems raised in the above background art.

[0005] In order to achieve the above purpose, the following technical solutions are further adopted:[[]]END]]

[0006] A braking device for a cable trolley includes two symmetrically arranged side plates, which are fixedly connected by connecting square steel. Symmetrically arranged moving arms are respectively installed on the outer sides of the two side plates. One end of the moving arm is connected to a brake that slides through the side plate through a connecting rod. A brake disc is connected to the end of the brake far from the connecting rod. An oil cylinder is installed between the ends of the two moving arms far from the connecting rod.

[0007] Two groups of wheels are symmetrically and rotatably installed between the inner walls of the two side plates, and the two groups of wheels are respectively located above and below the brake.

[0008] As a further improvement of the utility model, a support seat is fixedly connected to the outer wall of the side plate, the moving arm is rotatably connected to the support seat, and the distance from the connection between the moving arm and the support seat to the connection between the moving arm and the connecting rod is less than the distance from the connection between the moving arm and the support seat to the connection between the moving arm and the oil cylinder.

[0009] As a further improvement of the utility model, a valve body is installed on the outer side plate of one of the moving arms, and the valve body is used to control the operation of the oil cylinder.

[0010] As a further improvement of the utility model, the wheels are installed on a small shaft through cylindrical roller bearings, and the small shaft is fixedly penetrated through the side plate.

[0011] As a further improvement of the utility model, the connecting rod is rotatably connected to the brake and the moving arm.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The structure of this device is simple, with low manufacturing cost, small volume, and good braking effect. The valve body controls the extension of the oil cylinder, and the boom drives the symmetrically arranged brake discs to squeeze for braking. When the oil cylinder contracts, the braking is released; the brake and the braking are installed separately, which is convenient for replacement and reduces the maintenance cost of the device.
