Abstract
The invention discloses ultra-thin coal seam off pan shearer rocking arm shift fork clutch, splined shaft (8) is upper installs clutch spline housing (7), the side of clutch spline housing (7) connects sliding sleeve (6), rotate one end connection sliding block (5) of shift fork (3), slide block (5) inserts in the slide block slot (9) of sliding sleeve (6), the other end rotating shift fork (3) connects trace (2) one end through swivel pin (4), trace (2) other end connects clutch handle (1), is monolithically fabricated ultra-thin coal seam off pan shearer rocking arm shift fork clutch.The present invention achieves the upper shifting of clutch handle operating position by the structure using clutch yoke, practical, rational in infrastructure, and clutch stability is high.
Description
Technical field
The present invention relates to rocker arm of coal mining machine clutch, be specifically related to ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
Technical background
Coal-winning machine is a kind of mining coal cutting machinery, owing to working condition is poor, needs often to safeguard machine, overhaul, for preventing maloperation from causing casualties in maintenance process, and need to by the arrangement of clutch of cutting units separately.Traditional rocking arm arrangement of clutch is arranged in the center of axis hole more, to pull splined shaft, makes splined shaft vibration in spline housing realize the clutch of whole cutting units.The ultra-thin coal seam yield of coal industry is increasing at present, supporting coal-winning machine fuselage is the shortest, and the clutch handle position that is arranged in axis hole center is relatively low, the coal cinder scratching that clutch handle is easily transported on machine causes damage, the most relatively low position is also not easy to operative, even cannot transfer to clutch handle in the case of rocking arm is acted as a planted agent.
Summary of the invention
It is an object of the invention to: a kind of ultra-thin coal seam off pan shearer rocking arm shift fork clutch is provided, solve the problem that ultra-thin coal seam off pan shearer clutch position is relatively low, operation is difficult to, clutch is difficult, the arrangement of clutch making ultra-thin coal seam off pan shearer is rational in infrastructure, strong adaptability.
The present invention is to use following technical solution to realize: this rocking arm shift fork clutch includes clutch handle, trace, rotation shift fork, swivel pin, slide block, sliding sleeve, clutch spline housing and splined shaft, clutch spline housing is installed on splined shaft, the side of clutch spline housing connects sliding sleeve, rotate one end connection sliding block of shift fork, slide block inserts in the slide block slot of sliding sleeve, the other end rotating shift fork connects trace one end through swivel pin, the trace other end connects clutch handle, is monolithically fabricated ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
During work, pull clutch handle, clutch handle drives trace to slide in rocker arm of coal mining machine housing, while trace slides, shift fork being rotated by swivel pin to rotate, be so fixed on the slide block rotated on shift fork and just create movement, slide block drives sliding sleeve to produce axial displacement, the axial displacement of sliding sleeve drives clutch spline housing to move forward and backward, it is achieved clutch spline housing converts with the clutch of splined shaft.
The present invention is directed to that ultra-thin coal seam off pan shearer rocking arm clutch on-off handle position is low, easily scratching, the problem of clutch difficulty in girdle, the upper shifting of clutch handle operating position is achieved by the structure using clutch yoke, practical, rational in infrastructure, clutch stability is high.
Accompanying drawing explanation
Fig. 1 is the rocking arm shift fork clutch configuration schematic diagram of the present invention.
Fig. 2 is the structure sectional view of Fig. 1.
In figure: 1 clutch handle, 2 traces, 3 rotate shift fork, 4 swivel pins, 5 slide blocks, 6 sliding sleeves, 7 clutch spline housings, 8 splined shafts, 9 slide block slots.
Detailed description of the invention
As shown in Figure 1, 2, this rocking arm shift fork clutch includes clutch handle 1, trace 2, rotates shift fork 3, swivel pin 4, slide block 5, sliding sleeve 6, clutch spline housing 7 and splined shaft 8, clutch spline housing 7 is installed on splined shaft 8, the side of clutch spline housing 7 connects sliding sleeve 6, rotate one end connection sliding block 5 of shift fork 3, slide block 5 inserts in the slide block slot 9 of sliding sleeve 6, the other end rotating shift fork 3 connects trace 2 one end through swivel pin 4, trace 2 other end connects clutch handle 1, is monolithically fabricated ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
During work, pull clutch handle 1, clutch handle 1 drives trace 2 to slide in rocker arm of coal mining machine housing, while trace 2 slides, shift fork 3 being rotated by swivel pin 4 to rotate, be so fixed on the slide block 5 rotated on shift fork 3 and just create movement, slide block 5 drives sliding sleeve 6 to produce axial displacement, the axial displacement of sliding sleeve 6 drives clutch spline housing 7 to move forward and backward, it is achieved clutch spline housing 7 converts with the clutch of splined shaft 8.
