Description
Technical field
The present invention relates to mining equiments, and in particular to a kind of hydraulic prop with warning function.
Background technology
Hydraulic prop is widely used in coal mine down-hole tunnel and working face as support apparatus, in actual use by
It can change in the weight of carrying, the carrying pressure of hydraulic prop is also changing, and hydraulic prop has maximum carrying pressure,
When carrying pressure more than maximum, hydraulic prop can occur to damage phenomenon.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of hydraulic prop with warning function, the list
Body hydraulic prop can perceive the situation of carried pressure, and can carry out locally warning more than pressure set points, to remind operation
Personnel take treatment measures in time.
To achieve these goals, the present invention provides a kind of hydraulic prop with warning function, including movable post, cylinder body,
The cylinder base is equipped with pedestal, and cylinder body top is equipped with handle body, and movable post is located at cylinder interior and by being arranged on its lower end
The inner wall of piston head and the cylinder body is slidingly sealed cooperation, and the lower periphery of the cylinder body is set with valve seat, is set in the valve seat
There is triple-use valve, the triple-use valve is penetrated through by the liquid injection hole being radially arranged on cylinder body with inner chamber of cylinder block, and the inner chamber of cylinder block exists
Liquid injection hole top is equipped with for carrying out /V annular limiting stand to piston head lower end, is additionally provided in the valve seat and inner chamber of cylinder block
Pressure sensing, alarm and the controller of middle connection；
The pressure sensing is used to perceive the pressure of inner chamber of cylinder block, and sends superpressure electricity to controller when more than setting value
Signal；The controller is used to after superpressure electric signal is received alarm be controlled to alarm；The controller passes through electric power storage
Pond is powered.
By pressure sensor set can perceive cylinder interior pressure be more than setting value after make controller control
Alarm processed is alarmed, so as to be avoided that happening for hydraulic prop superpressure damage.
Further, the movable post top is fixedly connected with head cover.
Further, the head cover is circle, has a diameter larger than the diameter of movable post.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1st, movable post, 2, cylinder body, 3, pedestal, 4, handle body, 5, piston head, 7, valve seat, 8, triple-use valve, 9, liquid injection hole,
10th, annular stop platform, 11, pressure sensing shout, 12, alarm, 13, controller, 14, head cover.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of hydraulic prop with warning function, including movable post 1, cylinder body 2,2 bottom of cylinder body is set
Have a pedestal 3,2 top of cylinder body is equipped with handle body 4, movable post 1 be located at 2 inside of cylinder body and by be arranged on its lower end piston head 5 and
The inner wall of the cylinder body 2 is slidingly sealed cooperation, and the lower periphery of the cylinder body 2 is set with valve seat 7, three are equipped in the valve seat 7
With valve 8, the triple-use valve 8 is penetrated through by the liquid injection hole 9 being radially arranged on cylinder body 2 with 2 inner cavity of cylinder body, 2 inner cavity of cylinder body
Be equipped with to carry out /V annular limiting stand 10 to 5 lower end of piston head on 9 top of liquid injection hole, be additionally provided in the valve seat 7 with
Pressure sensing 11, alarm 12 and the controller 13 connected in 2 inner cavity of cylinder body；
The pressure sensing 11 is used to perceive the pressure of 2 inner cavity of cylinder body, and is sent when more than setting value to controller 13
Superpressure electric signal；The controller 13 is used to after superpressure electric signal is received alarm 12 be controlled to alarm；The control
Device 13 is powered by accumulator.
By pressure sensor set can perceive cylinder interior pressure be more than setting value after make controller control
Alarm processed is alarmed, so as to be avoided that happening for hydraulic prop superpressure damage.
Further, 1 top of movable post is fixedly connected with head cover 14.
Further, the head cover 14 is circle, has a diameter larger than the diameter of movable post 1.
