Background technique
In the prior art, back, especially return aircourse are supported using a large amount of hydraulic prop in coal mine roadway
With haulage drift adjacent to the place of working face, during the advance of the face, return aircourse and transportation roadway near working face
The pressure from surrounding rock in road is larger, and the stress variation for being used to support the hydraulic prop of back is larger, needs technology detection single
The support force of body hydraulic prop.During roadway surrounding rock pressure increase, without manifest signs, caused once pressure from surrounding rock is excessive
The damage of hydraulic prop, tunnel inner wall are shunk, and not only influence the normal use in tunnel, but also to the staff in tunnel
There are huge security risks.Therefore, it is badly in need of making a kind of pressure early warning pedestal of mine hydraulic prop, it is existing to solve
The problem of technology.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of pressure early warning bottom of mine hydraulic prop
Seat can not only provide conveniently for the stress situation of personnel monitoring's hydraulic prop, but also can prevent monomer hydraulic
Pillar breaks the safety for threatening staff.
The utility model is realized by following technical proposals：
A kind of pressure early warning pedestal of mine hydraulic prop, including hydraulic prop, the hydraulic prop
Including movable post and sleeve, the outer profile of the sleeve is formed as cylindrical, defines the axis along the cylinder in the sleeve
To extension and the hydraulic cavities of open at one end, the movable post are movably plugged on the hydraulic cavities along the open ports of the hydraulic cavities
It is interior, there is the sealing element for sealing the hydraulic cavities, the sleeve between the periphery wall of the movable post and the internal perisporium of the sleeve
Periphery wall be equipped with liquid-filling valve, the liquid-filling valve is connected to the hydraulic cavities and is used to that emulsification to be injected or excluded to the hydraulic cavities
Liquid, the bottom of the sleeve have pedestal, and the top of the pedestal has holding tank, and the sleeve separably cooperates described
In holding tank, the pressure early warning pedestal of the mine hydraulic prop further includes：Pressure detecting box, the pressure detecting box are set
The holding tank bottom and be folded between the sleeve and the pedestal, the pressure detecting box is connected to electrical nodes pressure
Table, the electric node manometer are electrically connected alarm by conducting wire.
Further, the sleeve is equipped with mounting portion, and the alarm is detachably mounted on the mounting portion.
Further, the alarm includes buzzer and warning lamp, the buzzer and the warning lamp with it is described
Electric node manometer electrical connection, and the buzzer and the warning lamp are in parallel.
Further, the periphery of the buzzer and the warning lamp is equipped with explosive-proof protector cover.
Further, it is connected between the pressure detecting box and the electric node manometer by detection pipe, the detection
The side wall that extends radially through the holding tank of the pipe along the holding tank.
Further, thickness of the pressure detecting box in the axial direction of the holding tank is less than or equal to the receiving groove depth
The one third of degree.
The utility model has the advantage that compared with prior art：The compression of the mine hydraulic prop of the application is pre-
Alarm device is detected single by the way that pressure detecting box is arranged between the sleeve and pedestal of hydraulic prop using pressure detecting box
Then the compression that body hydraulic pressure support is born utilizes the pressure of the electric node manometer detection pressure detecting box of connection pressure detecting box
Power situation.When the pressure of monomer pressure pillar is more than the setting pressure of electric node manometer, electric node manometer control alarm
Device is opened, and sound, which can not only occur, for the alarm being made of buzzer and warning lamp can also generate sparkling prompting, prevent because of lane
Noise is excessive or tunnel is turned in road influences the attention in the work human world.The compression early warning of mine hydraulic prop as a result,
Device not only can remind staff to replace hydraulic prop before hydraulic prop is damaged, moreover it is possible to
It reminds unrelated staff quickly to withdraw, hydraulic prop damage or country rock is prevented to be caving and cause bigger personal injury.
