Abstract
The utility model discloses a brake structure for a coal mine underground belt conveyor. The brake structure for the coal mine underground belt conveyor comprises a rotary shaft, wherein one end of the rotary shaft is installed on one end face of a box in a rotary mode, the other end of the rotary shaft is installed on a brake base in a rotary mode, one end of the brake base stretches into the box, a brake ring is fixedly installed on the portion, inside the box, of the rotary shaft through a spline, a friction plate set is arranged between the brake base and the brake ring, an annular piston cavity is further arranged on the brake base, an annular piston is installed in the annular piston cavity in a matched mode, the stretching-out end of the annular piston abuts against the friction plate set, a guide hole is formed in the other end of the annular piston, a spring is installed in the guide hole in a matched mode, the other end of the spring is located in a fixing hole in the brake base and is arranged on a limiting column in the fixing hole in a sleeved mode, and the limiting column is sleeved with a rubber sleeve. The brake structure for the coal mine underground belt conveyor has the advantages that the structural design is reasonable, the friction area can be enlarged, and the brake performance is improved; the situation that the spring is difficult to restore due to excessive deformation caused by stress can be avoided, the rubber sleeve can assist in restoration of the spring, and the automatic safety function is achieved.
Description
Technical field
The utility model relates to a kind of break, relates in particular to a kind of brake structural for belt conveyer at the bottom of coal mine.
Background technique
Existing brake structural is simple, and in the course of the work, although can reach braking effect, the friction area between friction plate is little, poor stop, and simultaneous reactions is slow, there is no automatic safety function, can not meet the requirement of keeping the safety in production at the bottom of coal mine.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of brake structural for belt conveyer at the bottom of coal mine is provided.
The utility model is achieved through the following technical solutions:
A kind of brake structural for belt conveyer at the bottom of coal mine, include rotating shaft, one end of described rotating shaft is rotatably installed in an end face of casing, the other end of described rotating shaft is rotatably installed on brake seat, one end of described brake seat extend in casing, in rotating shaft in described casing, be installed with brake hoop by spline, it is characterized in that: between described brake seat and brake hoop, be provided with friction plate group, on described brake seat, be also provided with annular piston chamber, in described annular piston chamber, coordinate annular piston is installed, the external part of described annular piston withstands in friction plate group, in the other end of described annular piston, be distributed with pilot hole, in described pilot hole, coordinate spring is installed, the other end of described spring is arranged in the fixed hole of brake seat, and be sleeved on the limited post in fixed hole, on described limited post, be set with rubber sleeve.
Described friction plate group includes still and moving plate, and described still is arranged on brake seat inserting end by internal spline interval, and described moving plate is arranged on brake hoop by external splines, and is inlaid between still.
Its principle is: by built-in multiple friction plate cluster frictions, reduce volume, increase friction area, strengthen braking ability; By the structure of the limited post in brake seat spring fixed hole, can avoid spring stress excessive deformation, be difficult to recover, can assist recovery by rubber sleeve, when hydraulic system fails or oil hydraulic pump are owing to quitting work suddenly, piston cavity pressure is zero, and maximum spring pressure acts in friction plate group, and therefore this device has automatic safety function.
The utility model has the advantages that:
The utility model reasonable in design, increases friction area, strengthens braking ability; Can avoid spring stress excessive deformation, be difficult to recover, can assist recovery by rubber sleeve, and there is automatic safety function.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
