Real-time monitoring disk brake with pressure sensor

Abstract

The invention discloses a real-time monitoring disk brake with a pressure sensor. The real-time monitoring disk brake with the pressure senor comprises a brake shoe, a cylinder, a brake body, the pressure sensor, a disk spring guide sleeve, an oil cylinder part, a disk-shaped spring group and a linkage mechanism, wherein the brake shoe are arranged on the cylinder through pressure plates on the two sides; the disk-shaped spring group is arranged on the part, tightly adhered to the oil cylinder, of the disk spring guide sleeve; the disk spring guide sleeve drives a sliding sleeve to perform piston motion in the brake body by the oil cylinder part; the bottom of the disk spring guide sleeve is connected with the bottom of the cylinder through the linkage mechanism; the pressure sensor is clamped between the disk spring guide sleeve and the top part of the cylinder; and the real-time detection of a positive pressure is realized. By the real-time monitoring disk brake with the pressure sensor provided by the invention, the positive pressure in a linear direction between the brake shoe and the oil cylinder can be detected directly; interference factors in the detection is reduced; the monitoring of the maximum positive pressure, the minimum positive pressure and the secondary brake positive pressure, and the real-time monitoring of pressure change in an overall process are realized; and the safety in utilization of a hoisting machine is improved.

Description

technical field [0001] The invention relates to a disk brake used for a hoist, in particular to a real-time monitoring disk brake with a pressure sensor. Background technique [0002] Disc brakes are hydraulic actuators used in the brake system of mine hoists. In the prior art, disc brakes are divided into two types: front-mounted oil cylinder device and rear-mounted oil cylinder device. The front-mounted oil cylinder device is easy to cause pressure oil leakage. Leakage to the brake disc will reduce the friction coefficient between the brake shoe and the brake disc, thereby affecting the braking torque and causing safety accidents. Moreover, the existing positive pressure detection means of disc brakes are mainly converted by detecting the oil pressure value, but the calculated positive pressure and There is a big difference in the actual positive pressure, and the accuracy cannot meet the requirements for use. If the deformation of the disc spring is used to convert the p...
