Embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, a kind of safety-type brake apparatus of pneumatic decompression suitable for mine of the present utility model,
7, static friction piece 8, movable friction plate 9 are covered including brake chamber 1, adjustment arm 2, camshaft 3, backing plate 4, quiet shell 5, piston 6, tooth, are moved
Shell 10, spring 11.Wherein movable friction plate 9 is connected by spline with dynamic shell 10, and static friction piece 8 is connected by spline with tooth set 7,
Both movable friction plate 9 and static friction piece 8 are spaced, and movable friction plate 9 and static friction piece 8 can move left and right along spline,
Under normality, certain gap is kept to be freely rotatable between movable friction plate 9, static friction piece 8.
As shown in Figures 1 to 4, the outside of brake chamber 1 of the present utility model sets adjustment arm 2, and the inside of brake chamber 1 includes
Push rod, when brake chamber 1 is passed through compressed gas, when such as compressed gas being 0.8MPa, the push rod of brake chamber 1 stretches out, and promotes
Adjustment arm 2 turns over an angle, such as 15 degree of selection.Adjustment arm 2 is connected with camshaft 3, and the rear end of camshaft 3 is fixed on backing plate 4,
Backing plate 4 sets piston 6 below, and the rear portion of piston 6 is movable friction plate 9 and static friction piece 8 arranged in a crossed manner.In the utility model, move
Friction plate 9 and static friction piece 8 are enclosed in dynamic shell 10, tooth set 7, in the confined space that is formed of quiet shell 5, make movable friction plate 9 and quiet
The friction of friction plate 8 will not have an impact to the external world, and then improve the security performance of the present apparatus.
As shown in Figures 1 to 4, the utility model tooth set 7 is fixedly mounted on quiet shell 5, is set between tooth set 7 and piston 6
Put spring 11；Static friction piece 8 and movable friction plate 9 are arranged in tooth set 7, and dynamic shell 10 is arranged on the rear portion of movable friction plate 9.
The course of work of the present utility model is：When brake chamber 1 is passed through compressed gas (0.8MPa), braking air chamber push rod
Stretched out under compressed gas effect, promote adjustment arm 2 to turn over an angle, be connected to the adjustment arm 2 on camshaft 3 with moving cam
Axle 3 turns over an angle simultaneously, and the rotation of camshaft 3 drives backing plate 4 to turn over an angle, and the rotation of backing plate 4 promotes piston 6
Move right, and then compress movable friction plate 9, the generation frictional force of static friction piece 8, caused frictional resistance moment prevents dynamic shell 10
