Abstract
The invention discloses a rocking arm and shift fork clutch for a bottom plate crawling type coal mining machine for an ultra-thin coal bed. A clutch spline sleeve (7) is arranged on a spline shaft (8), one side of the clutch spline sleeve (7) is connected with a slide sleeve (6), one end of a rotary shift fork is connected with a slide block (5), a slide block (5) is inserted into a slide block groove (9) of the slide sleeve (6), the other end of the rotary shift fork (3) is connected with one end of a linkage rod (2) through a hinge pin (4), and the other end of the linkage rod (2) is connected with a clutch handle (1), so as to integrally form the rocking arm and shift fork clutch for the bottom plate crawling type coal mining machine for the ultra-thin coal bed. The rocking arm and shift fork clutch has the advantages that operation positions of the clutch handle can be moved upwards through the clutch shift fork structure, the practicality is high, the structure is reasonable, and the 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, because working condition is poor, needs often to safeguard machine, overhaul, for preventing misoperation from causing casualties in maintenance process, and need by the engaging and disengaging gear of cutting portion separately.Traditional rocking arm engaging and disengaging gear 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 portion.The ultra-thin coal seam yield of current coal industry is increasing, supporting coal winning machine fuselage is all very short, and the clutch handle position being arranged in axis hole center is lower, the clutch handle easily coal cinder scratching be transported on machine causes damage, lower position is also not easy to operative simultaneously, even cannot transfer to clutch handle when rocking arm is acted as a planted agent.
Summary of the invention
The object of the invention is to: a kind of ultra-thin coal seam off pan shearer rocking arm shift fork clutch is provided, solve that ultra-thin coal seam off pan shearer clutch position is lower, operation not easily, the problem of clutch difficulty, make the engaging and disengaging gear of ultra-thin coal seam off pan shearer rational in infrastructure, strong adaptability.
The present invention adopts following technical solution to realize: this rocking arm shift fork clutch comprises clutch handle, continuous motion stem, rotation shift fork, swivel pin, slide block, sliding sleeve, clutch spline housing and splined shaft, splined shaft is installed clutch spline housing, 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 continuous motion stem one end through swivel pin, the continuous motion stem the other end connects clutch handle, overall formation ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
During work, pull clutch handle, clutch handle drives continuous motion stem to slide in rocker arm of coal mining machine housing, while continuous motion stem slides, rotated by swivel pin driven rotary shift fork, be fixed on the slide block rotated on shift fork like this 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, and the clutch realizing clutch spline housing and splined shaft transforms.
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 in girdle, clutch difficulty problem, by adopt the structure of clutch yoke achieve clutch handle operating position on move, practical, rational in infrastructure, clutch stability is high.
Accompanying drawing explanation
Fig. 1 is 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 continuous motion stems, 3 rotate shift fork, 4 swivel pins, 5 slide blocks, 6 sliding sleeves, 7 clutch spline housings, 8 splined shafts, 9 slide block slots.
Embodiment
As shown in Figure 1, 2, this rocking arm shift fork clutch comprises clutch handle 1, continuous motion stem 2, rotates shift fork 3, swivel pin 4, slide block 5, sliding sleeve 6, clutch spline housing 7 and splined shaft 8, splined shaft 8 is installed 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 continuous motion stem 2 one end through swivel pin 4, continuous motion stem 2 the other end connects clutch handle 1, overall formation ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
During work, pull clutch handle 1, clutch handle 1 drives continuous motion stem 2 to slide in rocker arm of coal mining machine housing, while continuous motion stem 2 slides, rotated by swivel pin 4 driven rotary shift fork 3, be fixed on the slide block 5 rotated on shift fork 3 like this 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, and realizes clutch spline housing 7 and transforms with the clutch of splined shaft 8.
Claims (1)
1. ultra-thin coal seam off pan shearer rocking arm shift fork clutch, is characterized in that, this rocking arm shift fork clutch comprises clutch handle (1), continuous motion stem (2), rotate shift fork (3), swivel pin (4), slide block (5), sliding sleeve (6), clutch spline housing (7) and splined shaft (8), 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 continuous motion stem (2) one end through swivel pin (4), continuous motion stem (2) the other end connects clutch handle (1), overall formation ultra-thin coal seam off pan shearer rocking arm shift fork clutch.
