An inner hole is arranged on the cylinder bottom 2, the travel sensor 7 is assembled in the hole, a deep hole for containing the travel sensor 7 is arranged on the axle center of the piston rod 9, a travel sensor magnet ring 8 is further installed on the piston rod 9, the magnet ring 8 is sleeved outside the travel sensor 7 and can move along the piston rod 9, an electrical socket 3 of the travel sensor is arranged outside the cylinder bottom 2 and is connected with an electric control system of a coal cutting machine through a signal cable, a displacement signal of the piston rod which is obtained by the travel sensor 7 is transmitted to the electric control system of the coal cutting machine, the height adjusting oil cylinder travel is displayed on an operation panel of the electric control system, and the position of a drum is displayed. The height adjusting oil cylinder of coal cutting machine utilizes the sensing technique for monitoring the displacement travel of the height adjusting oil cylinder of the coal cutting machine, the use is convenient, the monitoring effect is good, and the service life is long.
Description
Technical field
The utility model relates to flitting, and particularly a kind of coal mining machine roller that can detect is regulated coal winning machine adjust high cylinder highly.
Background technique
The present double-ended shearer that uses of coal mine fully-mechanized mining working, cylinder is installed on the rocking arm as the coal breakage and the mechanism of coalingging, and regulate the cylinder height by the swing of rocking arm, and the action of control rocking arm is adjust high cylinder.It mainly finishes the ascending, descending action of rocking arm, to adapt to the needs of different coal.Heightening of present domestic drum shearer cylinder mostly is manual, because the variation of geological conditions such as coal seam thickness variation, roof and floor fluctuating, if it is improper manually to heighten, cylinder will be cut top, base plate, cause such as load and uprush, the fault that causes cut, height-adjusting system or transmission link, even motor such as burns out at problem.Cutting rock produces spark, also has potential safety hazard.Address the above problem, just must monitor and protect the coal mining machine roller height-adjusting system.
Summary of the invention
Can not regulate the deficiency of highly monitoring to coal mining machine roller in order to solve prior art, the utility model provides a kind of coal winning machine adjust high cylinder, and it can realize coal mining machine roller is regulated the monitoring of height.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be:
The coal winning machine adjust high cylinder is made of cylinder barrel, cylinder bottom, piston rod, piston, guide sleeve etc.Its cylinder bottom is provided with endoporus, is equipped with stroke sensor in the hole; The axle center of its piston rod is provided with a deep hole that holds stroke sensor, and the stroke sensor magnet ring also is housed on the piston rod, and this magnet ring is enclosed within the stroke sensor periphery, moves with piston rod; Cylinder bottom is provided with the electrical socket of stroke sensor outward, and it is connected with the coal winning machine automatical control system by electrical plug, transducing signal cable.
The beneficial effects of the utility model are:
The coal winning machine adjust high cylinder utilizes the displacement stroke of sensory technique monitoring coal winning machine adjust high cylinder, and is easy to use, monitoring effect good, long service life.
Description of drawings
Accompanying drawing is the structural representation of the utility model coal winning machine adjust high cylinder.
Among the figure: the 1-sensor is stifled, 2-cylinder bottom, 3-electrical socket, 4-piston, 5-cylinder barrel, 6-guide sleeve, 7-stroke sensor, 8-sensor magnet ring, 9-piston rod.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The structure of the utility model coal winning machine adjust high cylinder is shown at Fig. 1.It is made up of cylinder barrel 5, cylinder bottom 2, piston rod 9, piston 4, guide sleeve 6, stroke sensor 7, sensor magnet ring 8, sensor stifled 1 etc.
Cylinder bottom 2 machining high-precisions are installed endoporus, assembling stroke sensor 7 hole in, and the outside that this hole is positioned at stroke sensor 7 is equipped with sensor and is blocked up 1.Piston rod 9 bores a deep hole to hold sensor 7 in the axle center on the original structure basis, also be equipped with stroke sensor magnet ring 8 on the piston rod 9, this magnet ring 8 is enclosed within stroke sensor 7 peripheries, moves with piston rod 9, so that respond to stroke sensor 7, produces the transducing signal of reflection piston rod stroke.The cylinder bottom 2 outer electrical sockets 3 that are provided with stroke sensor, the signal cable that the stroke sensing signal is drawn through electrical socket 3 is transmitted to the coal winning machine electric control part, and is presented on the automatical control system operation panel, thereby realizes monitoring and demonstration to the coal mining machine roller position.
Stroke sensor is the intrinsic safety type sensor, can monitor stroke and reach 1200mm.
Working principle:
The coal winning machine adjust high cylinder is articulated between cylinder rocking arm and the body, is the single telescopic oil cylinder of double-action, and piston rod is done linear reciprocating motion in oil cylinder.Stroke sensor 7 is fixed on the adjust high cylinder cylinder bottom 2, and sensor magnet ring 8 is fixed on the piston rod, and the deep hole in the piston rod 9 can hold stroke sensor 7.When cylinder action, stroke sensor 7 is motionless, sensor magnet ring 8 is along with piston rod 9 moves, relative travel sensor 7 is done straight line motion, after stroke sensor 7 produces the displacement signal of piston rod 9, be transferred to the coal winning machine automatical control system by signal cable, on the automatical control system operation panel, show the adjust high cylinder stroke, thereby show the position at cylinder place.
