Abstract
The utility model discloses an automatic rocker arm height displaying and adjusting system of a coal mining machine, comprising a machine body (6), a hydraulic cylinder (5) and a rocker arm (3); a first inclined-angle sensor (2) is arranged on the rocker arm (3), a second inclined-angle sensor (4) is arranged on the machine body (6), a solenoid valve (7) is connected on a control oil pipe of the hydraulic cylinder (5), the first inclined-angle sensor (2), the second inclined-angle sensor (4) and the solenoid valve (7) are eclectically connected with a programmable controller (10) which is electrically connected with a height display (9) and a control interface (10). The automatic rocker arm height displaying and adjusting system of the coal mining machine has the advantages of timely displaying the height of the rocker arm and controlling the height of the rocker arm, simple structure, low cost and convenient manufacturing.
Description
Technical field
The utility model relates to a kind of rocker arm of coal mining machine, particularly relates to a kind of rocker arm of coal mining machine and shows high and heighten automatic system.
Background technology
The structure that present rocker arm of coal mining machine is heightened structure is that the rocking arm of coal-winning machine is hinged on front fuselage, and the cylinder body of hydraulic cylinder is hinged on the fuselage, and the piston rod of hydraulic cylinder is hinged on the rocking arm, realizes heightening of rocking arm by the stretching of piston rod of hydraulic cylinder.Adopt the rocker arm of coal mining machine of this structure to heighten structure, heightening of rocking arm can not in time be fed back; Cylinder actual height and the coal-winning machine angle of climbing can not obtain real-time demonstration; The location of roller height, stop to realize full-automation; Cause the rocking arm swing excess of stroke easily, have bigger potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides a kind of rocker arm of coal mining machine of rocking arm height and timely control rocking arm height that can in time show and shows high and heighten automatic system.
In order to solve the problems of the technologies described above, the rocker arm of coal mining machine that the utility model provides shows high and heightens automatic system, comprise fuselage, hydraulic cylinder and rocking arm, on described rocking arm, be provided with first obliquity sensor, on described fuselage, be provided with second obliquity sensor, be connected with electromagnetic valve on the control oil channel of described hydraulic cylinder, described first obliquity sensor, second obliquity sensor and electromagnetic valve are electrically connected with programmable controller, and described programmable controller is electrically connected with and shows high display and control interface.
Adopt the rocker arm of coal mining machine of technique scheme to show high and heighten automatic system, owing on rocking arm, be provided with first obliquity sensor, on fuselage, be provided with second obliquity sensor, be connected with electromagnetic valve on the control oil channel of hydraulic cylinder, first obliquity sensor, second obliquity sensor and electromagnetic valve are electrically connected with programmable controller, programmable controller is electrically connected with and shows high display and control interface, first obliquity sensor and the actual pivot angle of second obliquity sensor output rocking arm and the angle of climbing of coal-winning machine; Programmable controller is used for collection, processing and the output of various data, signal; Electromagnetic valve is realized the control to hydraulic cylinder, realizes the position adjustment of rocking arm and cylinder and stops; Both but Artificial Control also can realize automatic control; The control interface is used for manually importing corresponding signal and data.The location of roller height, stop to have realized full-automation; The actual height and the actual mining height that show cylinder in real time; The angle of climbing that shows coal-winning machine in real time; The automaticity of complete machine and reliability improve.
In sum, the utility model is that a kind of rocking arm height and timely control rocking arm height and simple in structure, with low cost, easily manufactured rocker arm of coal mining machine of in time showing shows high and heighten automatic system.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1; rocking arm 3 front ends are provided with cylinder 1; rear end is hinged on the fuselage 6; piston rod of hydraulic cylinder 5 and fuselage 6 are hinged; the cylinder body of hydraulic cylinder 5 and rocking arm 3 are hinged; be provided with second obliquity sensor 4 on fuselage 6; be provided with first obliquity sensor 2 on rocking arm 3; be connected with electromagnetic valve 7 on the control oil channel of hydraulic cylinder 5; first obliquity sensor 2, second obliquity sensor 4 and electromagnetic valve 7 are electrically connected with programmable controller 10, programmable controller 10 is electrically connected with and shows high display 9 and control interface 8.
Referring to Fig. 1, first obliquity sensor 2 and the actual pivot angle of second obliquity sensor, 4 output rocking arms 3 and the angle of climbing of coal-winning machine; Programmable controller 10 is used for collection, processing and the output of various data, signal; When the position of rocking arm 3 and cylinder 1 exceeded safe range, programming controller 10 control electromagnetic valve 7 realized the control to hydraulic cylinder 5, realize the position adjustment of rocking arm 3 and cylinder 1 and stop, but both Artificial Control also can realize automatic control; Control interface 8 is used for manually importing corresponding signal and data.The location of cylinder 1 height, stop to have realized full-automation; The actual height and the actual mining height that show cylinder 1 in real time; The angle of climbing that shows coal-winning machine in real time; The automaticity of complete machine and reliability improve.
