Industrial hydraulic disc brakes

Abstract

An industrial hydraulic disk brake comprises a left brake caliper, a right brake caliper and a brake support, a piston of a brake-caliper oil hydraulic cylinder is a shaft type piston, the middle of the shaft type piston is provided with a shoulder, the shaft section of the upper portion of the shoulder of the piston is sleeved with a disc spring set, the shaft section of the lower portion of the shoulder of the piston is arranged in a hole in the bottom surface of an oil hydraulic cylinder block, the space below the shoulder of the piston is an oil cavity, a positioning nut is connected to a central screw hole in an upper cover of the brake-caliper oil hydraulic cylinder, an indicator is arranged in a thread hole in the center of the positioning nut, the lower end of the indicator abuts against the upper end face of the piston, four connection rods are placed in through holes in four corners of the oil hydraulic cylinder block, spring bolts are connected with the upper ends of the connection rods, the spring bolts are sleeved with springs, brake shoes are fixedly connected with the lower ends of the connection rods, and friction pieces are fixed below the brake shoes. The industrial hydraulic disk brake has the advantages that the structure is compact, the size is small, and the weight is light; clamping and stagnant phenomena of mechanical structures cannot occur; the friction pieces are convenient to install, debug and maintain, gaps are easy to adjust, and safety and reliability are high; applicability is high.

Description

technical field [0001] The application belongs to the technical field of industrial safety brakes, in particular to industrial hydraulic disc brakes. Background technique [0002] At present, the safety hydraulic caliper disc brakes widely used in large-scale lifting equipment used by steel plants, shipyards and other factories and mines rely on the force transmission of the mechanical structure to ensure the realization of the brake function. The structure of the safety type hydraulic caliper disc brake in the prior art is: the friction plate device is connected together with the pressure-bearing cover plate through the connecting rod and the connecting screw. The pressure-bearing cover plate is connected together with the positioning nut through screws. Wherein the positioning nut and the piston rod are connected by threads. The braking and release action of the brake is the action of the piston driving the friction plate device under the cooperation of the hydraulic oil...
