Abstract
A safety disc brake system for a long stroke pumping unit comprises a brake disc, two clamp plates, brake pins, a support, a brake block, a return spring, a cam, a link assembly, a brake handle, an adjusting bar, a cable, a brake handle clamp, a clamp spring, and a brake base. The brake disc is fixed at one end of a drive shaft of the pumping unit and locates between the two clamp plates. The brake disc and the clamp plates are all provided with a certain amount of holes, corresponding to any position. One brake pin is inserted into two opposing holes. The brake block is connected to the support through the return spring. One end of the brake block is 1-3 millimeters away from the edge of the brake disc, and the other end of the brake block contacts with a convex surface of the cam. The tail end of the cam is connected with the link assembly. The input end of the link assembly is connected with the brake handle. The brake clamp fits the arc tooth structure of the brake base. Frictional braking can be done by pulling the brake handle. The safety disc brake system has the advantages that pin braking and frictional braking can be achieved in the same, and the system is safe, reliable, simply operable and conventionally maintainable.
