The specific embodiment
Fig. 1 is that lifting speed reducer of the present invention is fixed on the schematic diagram on the revolving dial.As shown in Figure 1, the lifting speed reducer fixed structure of mining forward shovel of the present invention comprises a plurality of fixed parts, and each fixed part comprises a pair of fixedly ears or side handles of a utensil 21,22, monaural 11 and coupling assembling 3.
The a pair of fixedly ears or side handles of a utensil 21,22 are fixed on the bottom of lifting speed reducer 2, and the above-mentioned a pair of fixedly ears or side handles of a utensil 21,22 shapes are identical and be arranged in parallel, and have a determining deviation between two ears or side handles of a utensil.Each fixedly the ears or side handles of a utensil 21 or 22 central authorities all have the first through hole, and the shape of two the first through holes with two fixedly on the ears or side handles of a utensil position identical.Monaural 11 is fixed on the top of revolving dial 1, and has the second through hole corresponding to two the first through holes in the central authorities of monaural 11.Monaural 11 axially has certain thickness along the second through hole, and this thickness is equal to or slightly less than two the fixedly ears or side handles of a utensil 21,22 spacings.
A pair of expansion connecting sleeve 32 is separately positioned on the two ends of bearing pin 31.Expansion connecting sleeve 32 can carry out swelling by adjusting after installing bearing pin 31, so that expansion connecting sleeve 32 and bearing pin 31 and with a pair of fixedly ears or side handles of a utensil 21, the first through hole of 22 between cooperate and be interference fit, then make between expansion connecting sleeve 32 and the bearing pin 31 without relatively rotating, and and nothing relatively rotates between a pair of fixedly ears or side handles of a utensil 21,22, thereby make between bearing pin 31 and a pair of fixedly ears or side handles of a utensil 21,22 also without relatively rotating.
Fig. 4 is the cross-sectional schematic of swelling linking sleeve 32 in one embodiment of the invention, and as shown in Figure 4, swelling linking sleeve 32 comprises the first cambridge ring 32a, the second cambridge ring 32b, outside female connector 32c and a plurality of swelling screw 32d.Swelling linking sleeve 32 integral body ringwise, and its sidewall has breach (not shown) vertically.The first cambridge ring 32a and the second cambridge ring 32b are the cambridge ring that lateral wall is the inclined-plane, and its medial surface is connected to bearing pin 31.Outside female connector 32c has the female connector of flange 32e for central authorities, and there are a plurality of bolts hole at the edge of outside female connector 32c along axial distribution, wears for a plurality of tensioning screw 32d.When swelling linking sleeve 32 is installed in bearing pin 31 and one of them fixedly between the ears or side handles of a utensil 21 time, first and the inwall butt bearing pin 31 of cambridge ring 32a and the second cambridge ring 32b, the outer wall butt of outside female connector 32c is the first through hole of the ears or side handles of a utensil 21 fixedly.Has certain interval between the first cambridge ring 32a and the second cambridge ring 32b.A plurality of swelling screw 32d are between two cambridge rings and outside female connector 32c.When swelling screw 32d is tightened to drive the second cambridge ring 32b to right-hand motion shown in Figure 4, the first cambridge ring 32a moves right so the second cambridge ring 32b drives outside female connector 32c owing to be connected to adjusting pad 34 among Fig. 1 or the monaural 11 of revolving dial 1 and can't moving.Along with the first cambridge ring 32a and the second cambridge ring 32b are mutually close, gap between the two reduces, the inwall of the first cambridge ring 32a and the second cambridge ring 32b compresses bearing pin 31, and the outer wall of outside female connector 32c compresses the first through hole, make bearing pin 31, swelling linking sleeve 32 and fixedly between the ears or side handles of a utensil 21 without relative motion.
In an embodiment of the present invention, coupling assembling 3 also comprises at least one adjusting pad 34.Adjusting pad 34 is fastened on the bearing pin 31, the fixedly ears or side handles of a utensil 21 of lifting speed reducer 22,22 and the monaural 11 of revolving dial 1 between.Fig. 3 is the schematic diagram of adjusting pad 34 in one embodiment of the invention.As shown in Figure 3, adjusting pad 34 is with jagged 34a, can directly be fixed on bearing pin 31 by breach 34a, to reach the effect of being convenient to install.The effect of adjusting pad 34 is to clog described gap when monaural 11 and two fixedly have the gap between the ears or side handles of a utensil 21,22, to avoid rocking of lifting speed reducer.
In an embodiment of the present invention, as shown in Figure 2, fixed structure comprises four fixed parts, is arranged between lifting speed reducer 2 and the revolving dial 1 in the mode that forms rectangle respectively, so that firm connection to be provided.But the present invention is not as limit, and the user can increase or reduce the number of fixed part, as long as lifting speed reducer firmly can be arranged on the revolving dial.
The mounting means of lifting speed reducer fixed structure of the present invention is as follows:
(1) rigid enclosure 33 being installed in second through hole of monaural 11 of revolving dial 1, is interference fit between rigid enclosure 33 and the monaural 11 wherein, and rigid enclosure 33 is to install under the environment of cold charge.
(2) monaural 11 with revolving dial 1 stretches between the fixedly ears or side handles of a utensil 21,22 of lifting speed reducer 22, and with the second through hole and two the first through hole contrapositions.
(3) bearing pin 31 is inserted the fixing ears or side handles of a utensil 21, the first through hole of 22 and be arranged in the rigid enclosure 33 of the second through hole, bearing pin 31 is interference fits with rigid enclosure 33, bearing pin 31 need cold charges.
(4) swelling linking sleeve 32 is installed on bearing pin 31 and fixedly between the ears or side handles of a utensil 21,22 the first through hole from the two ends of bearing pin 31, and regulates swelling linking sleeve 32 and carry out swelling.
In other embodiments, if monaural 11 and the fixing excesssive gap of the ears or side handles of a utensil 21,22 both sides can insert adjusting pad 34 monaurals 11 and fixedly between the ears or side handles of a utensil 21,22, to eliminate the gap, prevent that lifting speed reducer from moving axially.
The present invention compared with prior art, contact between lifting speed reducer 2 and the revolving dial 1 is tightr, guaranteed that lifting speed reducer can not move axially, can prevent the reductor shake, prolong the application life of lifting speed reducer, in addition, lifting speed reducer fixed structure of the present invention is installed relatively simple, easy to maintenance, improved economic benefit.
