Hydraulic support is to be power with the highly pressurised liquid; A kind of coal-face support apparatus that combines by certain connected mode by some Hydraulic Elements and some hardwares; It can realize rising frame (roof supporting), frame falls and (disengaging top board), move frame, promote drag conveyor reach and a whole set of operation of roof control; And can reliable supporting top board, isolate the goaf effectively, prevent that spoil from getting into work plane, guarantees the required working space of work plane.
Existing hydraulic support can not be monitored roof pressure in real time, can not change with the pressure of top board the hydraulic pressure of Hydraulic Elements is made corresponding pressure adjustment.Bad adaptability, it is excessive and damage to tend to cause the top board part to bear pressure.
Summary of the invention
The technical problem that the utility model will solve is: a kind of flexible digital hydraulic support is provided, makes it can monitor the pressure of top board in real time.
In order to solve the problems of the technologies described above; The utility model comprises top board, base, hydraulic cylinder, hydraulic cylinder mount pad and computer; The lower end of hydraulic cylinder and hydraulic cylinder mount pad are rotationally connected, and the hydraulic cylinder mount pad is arranged on the base, accompany the roof pressure sensor between hydraulic cylinder mount pad and the base; The roof pressure sensor is connected with the sender unit I, and computer is connected with and is used to receive the signal receiving device that the sender unit I transmits.
For the elevating movement that makes top board more steady; Also include push pedal, push rod and push rod mount pad, the lower end of push rod and push rod mount pad are rotationally connected, and the push rod mount pad is arranged on the base; Accompany the push pedal pressure sensor between push rod mount pad and the base; The upper end and the push pedal of push rod are rotationally connected, and push pedal and top board are rotationally connected, and the push pedal pressure sensor is connected with the sender unit II that transmits to signal receiving device.Can monitor push pedal pressure in real time.
Can fix for push pedal position when top board is worked, described push rod, push rod mount pad and push pedal pressure sensor have two covers, and a plurality of push rod connecting holes of on the push pedal length direction, arranging are arranged in the push pedal.
More steady for the elevating movement that makes top board, described hydraulic cylinder, hydraulic cylinder mount pad and roof pressure sensor have two covers.
The beneficial effect of the utility model is: the utility model can be monitored the pressure from top board in real time, comprises the dynamic pressure that reasons such as static pressure at right angle and rock movement or coal seam compression form.This pressure can showing through computer real-time.Can in time adjust hydraulic pressure through the variation of pressure changes.Both can prevent the generation of the useful event of collapsing of top board, and can prolong the application life of hydraulic support again.Its compliance is strong, and supporting efficient is high, and is safe, has improved hydraulic support application life.Having realized that the long-distance intelligent of support apparatus controls, is large-scale comprehensive mining machineryization, intelligent requisite intelligent apparatus.
