Tracheae connects.Piston 12 is provided with annular breach in the part close to bushing 13, and annular breach is surrounded the by bushing 13 and cylinder sleeve 11
Two cavitys 113, the side wall of cylinder sleeve 11, which is provided with, to be used to connect the second cavity 113 and the second extraneous through hole 114, in use, second
Through hole 114 is used to connect with breather pipe or blast pipe.
Part of the side wall of cylinder sleeve 11 between the first cavity 111 and the second cavity 113 is Part I, Part I
Inwall circumferentially arranged with annular groove 115, Part I is additionally provided with for connecting annular groove 115 and extraneous third through-hole 116.
It should be noted that the quantity of annular groove 115 can be one, or two or more.Annular groove 115 it is transversal
Face shape can be semicircle, arc, rectangle, trapezoidal or other shapes.
When being collaborated between the first cavity 111 and the second cavity 113, gas can be flowed into annular groove 115, so
Afterwards the external world is rejected to from third through-hole 116.
Brake component 14 is arranged on the upper end of piston 12.In present embodiment, brake component 14 is fixed on work by keep plate 16
The upper end of plug 12, brake component 14 are located at the side of the remote piston 12 of keep plate 16.The one of the remote brake component 14 of keep plate 16
Side is provided with annular protrusion 161.Annular protrusion 161 is provided with guide 163, side wall and the annular protrusion 161 of cylinder sleeve 11
Corresponding part is Part II, and the part that the outer wall of Part II is corresponding with guide 163 is provided with guide groove 162, leads
It is slidably matched to part 163 and guide groove 162, so, not only acts as to move up and down for keep plate 16 and play a part of guiding, also rise
The effect rotated to limitation keep plate 16.
The position of the close openend of cylinder sleeve 11 is additionally provided with locating part 17, and locating part 17 is loop configuration, locating part 17 with
The lateral wall threaded connection of cylinder sleeve 11, screws locating part 17, locating part 17 can move along the axis direction of cylinder sleeve 11.Locating part
17 primarily serve spacing effect are carried out to keep plate 16, during maintenance, when keep plate 16 is in jack-up state, can screw limit
Position part 17, makes locating part 17 withstand keep plate 16, prevents keep plate 16 from falling.
Locking member 171 can also be set on the outer peripheral face of locating part 17, and when locking member 171 is locked, locating part 17 can not turn
It is dynamic.
In order to ensure the air-tightness of brake, the first sealing can be set in the position corresponding with Part I of piston 12
Circle 121, the quantity at least two of the first sealing ring 121, the first sealing ring 121 is distributed in the both sides up and down of annular groove 115, extremely
Rare first sealing ring 121 is relative to annular groove 115 closer to the first cavity 111, at least phase of one first sealing ring 121
For annular groove 115 closer to the second cavity 113.
The setting of first sealing ring 121 so that the gas in the first cavity 111 is not easy between piston 12 and cylinder body
Gap is flowed into the second cavity 113, or the gas in the second cavity 113 is not easy the clearance flow between piston 12 and cylinder body
Enter into the first cavity 111.
It should be noted that the first sealing ring 121 can select V-shaped seal ring, U-shaped sealing ring, O-ring seal or Y types
Sealing ring etc..
It should also be noted that, the size of annular groove 115 can process as needed, the side of the opening of annular groove 115
Edge is blunt, ensures that the first sealing ring 121 can easier slip over annular groove 115 in an assembling process, and will not be to first
Sealing ring 121 causes to damage.
At least one second sealing ring 122 also is provided between piston 12 and bushing 13.It should be noted that the second sealing ring
122 can select V-shaped seal ring, U-shaped sealing ring, O-ring seal or y-type seal ring etc..
At least one 3rd sealing ring 123 also is provided between the inwall of bushing 13 and cylinder sleeve 11.It should be noted that the 3rd
Sealing ring 123 can select V-shaped seal ring, U-shaped sealing ring, O-ring seal or y-type seal ring etc..
The operation principle that the novel pneumatic that the utility model embodiment provides resets brake is as follows：
When to be braked, when being passed through gas from first through hole 112 to the first cavity 111, while the gas in the second cavity 113
Body excludes from the second through hole 114, and piston 12 moves upwards, and now brake is in braking jack-up state；When to be resetted, from
Two through holes 114 to the second cavity 113 be passed through gas when, while the gas in the first cavity 111 excludes from first through hole 112, living
Plug 12 moves downward, and now brake is in reset state.
The novel pneumatic that the utility model embodiment provides resets brake, and its is simple in construction, easy to use, can be compared with
Good prevents occurring the phenomenon collaborated between the first cavity 111 and the second cavity 113, avoids the occurrence of the feelings that brake can not reset
Condition occurs.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former
Within then, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
