A kind of single cylinder short-wall coal-winning machine mining height locating device, comprises fixed bin 1, rotary encoder 2, I axle 3, follower gear 4, II axle 5, back shaft group 6, driving gear 8; Described driving gear 8 is arranged on revolving rocker arm axle 9, and the integral installation of revolving rocker arm axle is inner at fuselage 7; Back shaft group 6 is supported in fuselage 7 hole slot, and bearing 16 is installed in back shaft endoporus; II axle 5 is supported by bearing 16, and follower gear 4 is fixed on II axle 5 left end, and engages with driving gear; I axle 3 is fixing to be inserted in rotary encoder 2 rotor, rotary encoder 2 integral installation is in fixed bin 1, fixed bin 1 is installed downwards by body shell 7 top, and II axle groove 15 aligns with I crown of roll groove 14 and blocks, and rotary encoder cable is drawn through hole 10 on fixed bin 1.
There is certain proportionate relationship in rocking arm pivot angle and mining height.Rocking arm swings and drives revolving rocker arm axle and driving gear to rotate, and follower gear and II axle swing thereupon, and I axle and rotary encoder also can synchronous axial system.Therefore measure rotary encoder pivot angle and can calculate mining height.
Further, described back shaft group 6 two ends are located by back-up ring, and bearing 16 two ends are located by back-up ring.
Further, at fixed bin left end with sealing gasket 11 and end cap 12, mounting framework oil sealing 13 in right-hand member hole slot.
Further, back shaft group 6 right-hand member installs O shape circle 17.
A localization method for single cylinder short-wall coal-winning machine mining height locating device according to claim 1, the angle of revolution of rocking arm equals the angle of revolution of driving gear 8.The rotor angle of revolution of rotary encoder 2 is equal to the angle of revolution of follower gear 4, and therefore the pivot angle ratio of rotary encoder and rocking arm is exactly the ratio of gear of main driven gear; According to the proportionate relationship of rocking arm pivot angle and mining height, namely automatically calculate the mining height of coalcutter by the rotary encoder anglec of rotation, realize the mining height location of short-wall coal-winning machine.
The utility model beneficial effect is: provide a kind of mining height measuring method being applicable to existing short-wall coal-winning machine structure, effectively can solve mining height location in the design of intelligent short-wall coal-winning machine and be difficult to the problem realized; This apparatus structure is simple, easy and simple to handle, data are accurate.
