Both pads are spaced, and movable friction plate and static friction piece can be moved left and right along spline, movable friction plate, static friction under normality
Gap is kept between piece；Set outside described brake chamber includes push rod, the push rod of brake chamber inside adjustment arm, brake chamber
Stretch out and promote adjustment arm rotation；Described adjustment arm is connected with camshaft, and cam shaft rear end is fixed on backing plate, is set behind backing plate
Piston is put, piston rear portion is movable friction plate arranged in a crossed manner and static friction piece；Described tooth set is fixedly mounted on quiet shell, in tooth
Spring is set between set and piston；Static friction piece and movable friction plate are arranged in tooth set, and dynamic shell is arranged on movable friction plate rear portion.
According to the pneumatic decompression safety-type brake apparatus as described above for being applied to mine, it is characterised in that：Described
Interval scope between movable friction plate, static friction piece is 3mm between 4mm.
According to the pneumatic decompression safety-type brake apparatus as described above for being applied to mine, it is characterised in that：Described
The push rod of brake chamber, which stretches out, promotes adjustment arm to rotate 15 degree.
According to the pneumatic decompression safety-type brake apparatus as described above for being applied to mine, it is characterised in that：Described
Brake chamber uses increase automatic parking brake spring inside double loop brake chamber, brake chamber.
The beneficial effects of the invention are as follows：One is to employ aerobraking, is not in hydraulic oil leakage and reduces or even lose
Go the danger of braking function；Two be simple in construction, and cost is more cheap, improves the reliability of braking ability；Three be to use
Double loop brake chamber, in air-channel system failure no pressure, under the spring-force driven dual that tripping spring is produced, promotes system

Embodiment
Technical scheme 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 invention, including
Brake chamber 1, adjustment arm 2, camshaft 3, backing plate 4, quiet shell 5, piston 6, tooth set 7, static friction piece 8, movable friction plate 9, dynamic 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, dynamic friction
Both piece 9 and static friction piece 8 are spaced, and movable friction plate 9 and static friction piece 8 can be moved left and right along spline, under normality,
Certain gap is kept to be freely rotatable between movable friction plate 9, static friction piece 8, this can be intermittently 3mm between 4mm.
As shown in Figures 1 to 4, the outside of brake chamber 1 of the invention sets adjustment arm 2, and the inside of brake chamber 1 includes pushing away
Bar, when brake chamber 1 is passed through compressed gas, when such as compressed gas is 0.8MPa, the push rod of brake chamber 1 stretches out, and promotes and adjusts
Whole 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, pad
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 present invention, movable friction plate 9
It is enclosed in static friction piece 8 in the confined space that dynamic shell 10, tooth set 7, quiet shell 5 are formed, makes movable friction plate 9 and static friction piece 8
Friction will not produce influence to external world, and then improve the security performance of the present apparatus.
As shown in Figures 1 to 4, tooth set 7 of the present invention is fixedly mounted on quiet shell 5, and bullet is set between tooth set 7 and piston 6
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 present invention the course of work be：When brake chamber 1 is passed through compressed gas (0.8MPa), braking air chamber push rod is in pressure
The effect of contracting gas is lower to stretch out, and promotes adjustment arm 2 to turn over an angle, the adjustment arm 2 being connected on camshaft 3 drives camshaft 3
An angle is turned over 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 to the right
Motion, and then movable friction plate 9, the generation frictional force of static friction piece 8 are compressed, produced frictional resistance moment prevents dynamic shell 10 from rotating,
And then brake brake apparatus；After end of braking, brake chamber 1 is retracted, and camshaft 3 and the return of backing plate 4 is driven, in spring force
Piston 6 is promoted to be moved to the left and reset under pressure, so that kinematics and static friction piece is separated, frictional resistance moment disappears, and releases braking.
It is used as the further scheme of the present invention：The brake chamber 1 of the present invention can use double loop brake chamber, brake chamber
1 inside increase automatic parking brake spring, when under parked state, or during air-channel system failure no pressure, in braking
Under the spring-force driven dual that spring is produced, promote the push rod of brake chamber 1 to stretch out, with above-mentioned braking principle, realize the parking of vehicle
And safety arrestment；Such as air-channel system normally, it works according to above-mentioned normal mode of operation.
