Abstract
A broken-tiles gravity brake comprises a brake block, an axis pin, a brake arm, a housing, a tie rod, a long boomed lever, a gravity lever, a hydraulic thruster, a short lever, a rotating shaft, a flat key, a long lever and a clump weight. The brake block is connected with the brake arm through the axis pin; the lower of the brake arm is connected with the housing; the upper of the brake arm is connected with the tie rod; the tie rod is connected with the long boomed lever; the long boomed lever is separately connected with the brake arm; the gravity lever and the hydraulic thruster through the axis pin. The gravity lever is connected with the short lever; the rotating shaft is fixed on the housing; the two ends of the rotating shaft is separately connected with the short lever and the long lever through the flat key; the other end of the long lever is connected with the clump weight. The lower part of the hydraulic thruster is connected with the housing through the axis pin. The device has the advantages of compact structure, secure and reliable, small using space, convenient installation, and easy operation.
Description
Technical field
The utility model relates to break, is specifically related to a kind of tile fragment formula gravity brake that is used on the mine winch.
Background technique
At present, the tile fragment break that domestic existing mine winch is used, its brake lever is culdy, and this brake structural is loose, and it is big to take up room, and inconvenience is installed.
Summary of the invention
The purpose of this utility model be to provide a kind of compact structure, safe and reliable, tile fragment formula gravity brake little, easy for installation, easy operating takes up room.
The technological scheme that the utility model adopted is: tile fragment formula gravity brake is made up of brake shoe, bearing pin, brake arm, frame, drag link, long-armed lever, gravity pull bar, hydraulic thrust device, short connecting lever, rotating shaft, flat key, long connecting lever and balancing weight.Brake shoe is connected with brake arm by bearing pin, and the brake arm lower end links to each other with frame, and the brake arm upper end is connected with drag link, and drag link links to each other with long-armed lever, and long-armed lever is connected with brake arm, gravity pull bar and hydraulic thrust device respectively by bearing pin.The gravity pull bar links to each other with short connecting lever, and rotating shaft is fixed on the frame, and the rotating shaft two ends all are connected with long connecting lever with short connecting lever respectively by flat key, and the long connecting lever the other end links to each other with balancing weight.Hydraulic thrust device lower end is connected with frame by bearing pin.
During use, hydraulic driver lifts or depresses long-armed lever left end, and long-armed lever and drag link drive brake arm swing several angle, brake shoe is declutched or brakes.During proper functioning, long-armed lever left end is lifted in the hydraulic driver energising, and brake shoe is in the state of declutching; When running into emergency episode or other accident, the hydraulic driver outage, the gravity pull bar is depressed long-armed lever left end, and brake shoe is in braking state immediately, thereby realizes safety brake.
The utlity model has following advantage: brake lever adopts long-armed lever, replaces traditional culdy, compact structure, and safe and reliable, it is little to take up room, easy for installation, easy operating.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
