Abstract
The utility model discloses a remote pressure relief controller for a hydraulic prop. The remote pressure relief controller for the hydraulic prop consists of a tubular cylinder, a piston and a top cover, and is connected to one end close to an unloading valve of a three-use valve. A rubber tube port connected with an oil pump is formed in the front end face of the tubular cylinder of the controller, and the inner wall surface of the rear end of the tubular cylinder is connected with the hollow top cover. And the top cover is connected on one end of the three-use valve, close to the unloading valve. A matched piston is arranged in the cylinder. A jacking rod connected with the other surface of the piston penetrates through the top cover, and then is contacted with the unloading valve on the three-use valve. When pressure is required to be relieved, hydraulic oil delivered by an oil pump is injected into the cylinder through the rubber tube port to drive the piston to move, the jacking rod on the piston jacks the unloading valve on the three-use valve to realize the pressure relief of the hydraulic prop. Operation personnel can realize the pressure relief of a single hydraulic prop through remote operation without entering a working plane, so that personnel injury accidents are effectively avoided, and the controller is safe and reliable.
Description
Technical field
The utility model relates to the corollary apparatus of colliery hydraulic prop, specifically is a kind of long-range hydraulic prop release controller.
Background technology
At present, there is a triple-use valve in the colliery with hydraulic prop is all supporting, is disposed with one way valve unit, feather valve unit and valve unit by routine in the triple-use valve.Feather valve when falling post in the triple-use valve all relies on manual release, need force safety valve to move with instrument, and the compression unloaded spring releases hydraulic oil, accomplishes the unloaded operation of hydraulic prop.Because operating personnel must get into the scope of operation near hydraulic prop work, therefore operating personnel are constituted bigger potential safety hazard, the personnel that often cause when supporting surface goes wrong injure and bring bigger direct economic loss thus.
Summary of the invention
In order to address the above problem, the utility model provides a kind of long-range hydraulic prop release controller, and the triple-use valve supporting to hydraulic prop carries out long-range release, effectively avoided the generation of personnel's injury accidents, guarantees operating personnel's life safety.
The utility model is realized through following technical scheme:
A kind of long-range hydraulic prop release controller; It is characterized in that this long-range hydraulic controller is made up of cylinder body, piston and the top cover of tubular and is connected feather valve one end near triple-use valve; The controller cylinder body front end face of tubular has the sebific duct interface, the rear end that connect oil pump to link to each other with hollow top cover at internal face, and top cover is connected on the triple-use valve end near feather valve; A supporting piston is housed in the cylinder body, the push rod that the piston another side connects pass behind the top cover with triple-use valve on feather valve contact; When needing release, the hydraulic oil that oil pump is carried is injected in the cylinder body by the sebific duct interface and promotes piston motion, and the feather valve that the push rod on the piston withstands on the triple-use valve makes the hydraulic prop pressure release.
Described top cover carries jack letting out of side wall surface and triple-use valve and links to each other through the fixture cooperation.
O type circle is housed on the described piston cooperates the formation hermetically-sealed construction with inboard wall of cylinder block.
This long-range hydraulic prop release controller that the utility model proposes, operating personnel need not get into the scope of operation, remote-controlled operation can be carried out release to hydraulic prop, have therefore effectively avoided the generation of personnel's injury accidents, and are safe and reliable.The release controller utilizes letting out of original triple-use valve to carry jack and is fixedly connected, and needn't do structural adjustment, thereby implement easily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the assembly structure sketch map of the utility model and triple-use valve.
Label in Fig. 1～2 is: 1-sebific duct interface, 2-cylinder body, 3-piston, 4-O type circle, 5-push rod, 6-top cover, 7-fixture, 8-triple-use valve.
The specific embodiment
Existing triple-use valve laterally is installed on the hydraulic prop and works, and is disposed with one way valve unit, feather valve unit and valve unit by routine in the triple-use valve.
As shown in Figure 1, the long-range hydraulic prop release of the kind that the utility model provides controller, supporting use solves accident potential under the coal mine on original triple-use valve.
This long-range hydraulic controller is made up of cylinder body 2, piston 3 and the top cover 6 of tubular and is connected feather valve one end near triple-use valve 8; Controller cylinder body 2 front end faces of tubular have the sebific duct interface 1, the rear end that connect oil pump to link to each other through screw thread with the top cover lateral surface at internal face; Top cover is connected on the triple-use valve end near feather valve: the letting out of roof side wall and triple-use valve carried a jack and is connected through fixture 7, and said fixture can be screw or latch; A supporting piston 3 is housed in the cylinder body, and the O type circle on the piston cooperates the formation hermetically-sealed construction with inboard wall of cylinder block.The push rod 5 that the piston another side connects pass behind the top cover with triple-use valve on feather valve contact; When needing release, the hydraulic oil that oil pump is carried is injected in the cylinder body by the sebific duct interface and promotes piston motion, and the feather valve that the push rod on the piston withstands on the triple-use valve makes the hydraulic prop pressure release.
