Embodiment
For the technological means and effect that the utility model is reached predetermined purpose and taken is expanded on further, below in conjunction with accompanying drawing
And embodiment describes in detail as follows to specific embodiment of the present utility model, architectural feature and its effect.
Reference picture 1, Fig. 2 and Fig. 3, present embodiment discloses coal-winning machine chain wheel replacing device, including two jack 3, set
The fixed plate above jack 3 and the leading screw 1 for fixing coal-winning machine bearing pin are put, leading screw 1 is consolidated after passing through fixed plate with bearing pin
Fixed connection, leading screw 1 are fixedly connected with nut 11, and jack 3 is used to extract bearing pin so that coal-winning machine sprocket wheel departs from frame.More
When changing coal-winning machine sprocket wheel, it need to only remove for the cable trough clamping plate of observation check and correction bearing pin position and consolidating for rib side coal-winning machine sprocket wheel
Determine frame bolt and back-up ring, coal-winning machine chain wheel replacing device of the present utility model is directed at bearing pin, tightens leading screw 1；Subsequent two people is same
When operate two jack 3, bearing pin is extracted, now coal-winning machine sprocket wheel automatically disengages frame；Will by operating rocker arm of coal mining machine
Fuselage lifts, and takes out old chain wheel, is put into new sprocket wheel；Last operation rocker arm of coal mining machine falls fuselage, installs bearing pin, back-up ring successively
And after fixed mount bolt, sprocket wheel is changed and finished.Therefore, the utility model is simple in construction, easy to operate, and coal-winning machine is changed saving
While the sprocket wheel activity duration, operating efficiency is improved, saves manpower and materials.
In actual applications, the preferred steel plate 2 of the fixed plate of the present embodiment, steel plate 2 are provided with two and are used to fix jack 3
Screw rod, two jack 3 are fixedly connected with screw rod respectively.The purpose so set is more changed the outfit to increase coal-winning machine sprocket wheel
The rigidity put, improve the service life of the device.The present embodiment on steel plate 2 by welding two screw rods, screw rod and two thousand
