Description
Technical field
The utility model is related to a kind of double general flame-proof type electro hydraulicthrusters of pressure, belong to technical field of hydraulic pressure.
Background technology
Currently, power hydraulic pressure mechanical brake is by band brake apparatus（Brake arm）And driving device（Electro hydraulicthruster）
Two large divisions is constituted.Electro hydraulicthruster is generally made of motor, hydraulic cylinder, piston, impeller and push rod.It is to utilize impeller
High speed rotation, the piston in hydraulic cylinder generates pressure difference, pushes piston and push rod to rise rapidly, push rod is further through system above and below
Dynamic device lever system drives packet brake gear, realizes the mechanical braking to host.Patent CN200920091213.4 discloses one kind
High-voltage explosion-proof type electro-hydraulic thruster is provided with balance gas chamber in structure in cylinder body, for storing enough hydraulic oil,
The pressure of stabilizing solution pressure oil is used in the pusher course of work.But pusher is during the work time, and initial stage needs larger hydraulic pressure
Power improves braking efficiency quickly to push push rod, and the hydraulic coupling that the pusher impeller of the prior art is provided in initial start stage compared with
It is small, braking efficiency is affected, and when the later stage reaches stroke limit, the impeller of normal rotation still provides larger hydraulic coupling, right
Entire braking system will generate larger impact.Although balance gas chamber can play the role of stabilizing solution pressure, can not solve
State problem.
Utility model content
The purpose of this utility model is to provide a kind of double general flame-proof type electro hydraulicthrusters of pressure, concrete scheme is：
A kind of double general flame-proof type electro hydraulicthrusters of pressure, including cylinder body, cylinder body is interior to be equipped with cylinder sleeve and is connected to cylinder sleeve
Balance gas chamber, piston is equipped in cylinder sleeve, piston is connected with push rod, and the front end of cylinder sleeve is equipped with the leaf being sequentially connected with fire-proof motor
Wheel, the main air chamber and accessory air-space for balancing gas chamber and including interconnected, the main air chamber are located at the inside of accessory air-space, accessory air-space
Elastic diaphragm layer is equipped between main air chamber, accessory air-space is connected with compressed air pipe fitting.
Further, the inner side and outer side of the elastic diaphragm layer is equipped with grating type position-limited rack, grating type position-limited rack with
There are spacing between elastic diaphragm layer.
Further, the elastic diaphragm layer is fluororubber layer.
Further, guide ring is equipped between the cylinder sleeve and impeller.
The beneficial point of the utility model is：This programme is arranged to main gas on the basis of existing technology, by balance gas chamber
The composite construction of room and accessory air-space, main air chamber still function as the effect of stabilizing solution pressure；Bullet is set between main air chamber and accessory air-space
Property membrane layer, elastic diaphragm layer separates main air chamber and accessory air-space, and accessory air-space passes through compressed air hose and injects pressure-air, dimension
Certain air pressure is held, in initial start stage, the hydraulic coupling that impeller generates is relatively low, and the air pressure in accessory air-space forces elastic diaphragm layer inwardly
Deformation is generated, to generate extruding to the space in cylinder body, aux. pressure can be provided in initial start stage, improve braking efficiency；
And after in the later stage, push rod reaches stroke limit, elastic diaphragm layer can play cushioning effect, mitigate the impact that braking system is subject to
Power.
In improvement project, grating type position-limited rack is set in the inner side and outer side of elastic diaphragm layer, elastic diaphragm can be prevented
Layer generates excessive deformation and fails, and limit distance is determined according to the deformability of elastic diaphragm layer.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
