The specific embodiment
Fig. 1 is that lifting speed reducer of the present invention is fixed on the schematic diagram on 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 between two ears or side handles of a utensil, tool is at regular intervals.Each fixedly the ears or side handles of a utensil 21 or 22 central authorities all there is 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 fixedly spacing of the ears or side handles of a utensil 21,22.
Coupling assembling 3 is for connecting a pair of fixedly ears or side handles of a utensil 21,22 and monaural 11.In an embodiment of the present invention, coupling assembling 3 comprises a bearing pin 31, a pair of expansion connecting sleeve 32 and a rigid enclosure 33.Bearing pin 31 passes the first through hole and the second through hole when monaural 11 stretches between a pair of fixedly ears or side handles of a utensil 21,22, so that a pair of fixedly ears or side handles of a utensil 21,22 of lifting speed reducer and the monaural 11 of revolving dial are linked together.Rigid enclosure 33 is installed in the second through hole, and after bearing pin 31 penetrates, is positioned at the middle part of bearing pin 31.Cooperation between rigid enclosure 33 and bearing pin 31 is interference fits, and with the second through hole of monaural 11 be interference fit, make not relatively rotate between rigid enclosure 33 and monaural 11.Rigid enclosure, for the very little hard linking sleeve of distortion, is steel bushing in one embodiment.
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 the first through hole of a pair of fixedly ears or side handles of a utensil 21,22 between coordinate and be interference fit, make between expansion connecting sleeve 32 and bearing pin 31 without relatively rotating, and and between a pair of fixedly ears or side handles of a utensil 21,22, nothing relatively rotates, 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.Ringwise, and its sidewall has breach (not shown) vertically to swelling linking sleeve 32 integral body.The first cambridge ring 32a and the second cambridge ring 32b are the cambridge ring that lateral wall is inclined-plane, and its medial surface is connected to bearing pin 31.Outside female connector 32c is the central female connector with flange 32e, and there are a plurality of bolts hole at the edge of outside female connector 32c along axial distribution, for a plurality of tensioning screw 32d, wears.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.Between the first cambridge ring 32a and the second cambridge ring 32b, there is certain interval.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 Fig. 4, the first cambridge ring 32a is owing to being connected to the monaural 11 of adjusting pad 34 in Fig. 1 or revolving dial 1 and cannot moving, so the second cambridge ring 32b drives outside female connector 32c to move right.Along with the first cambridge ring 32a and the second cambridge ring 32b 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 bearing pin 31, between the fixedly ears or side handles of a utensil 21,22 and the monaural 11 of revolving dial 1 of lifting speed reducer 22.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 installation.The effect of adjusting pad 34 is to clog described gap when monaural 11 and two fixedly have 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 revolving dial 1 respectively, so that firm connection to be provided to form the mode of rectangle.But the present invention is not as limit, and user can increase or reduce the number of fixed part, as long as lifting speed reducer firmly can be arranged on revolving dial.
The mounting means of lifting speed reducer fixed structure of the present invention is as follows:
(1) rigid enclosure 33 being arranged in second through hole of monaural 11 of revolving dial 1, is wherein interference fit between rigid enclosure 33 and monaural 11, and rigid enclosure 33 is to install under the environment of cold charge.
(2) monaural of revolving dial 1 11 is stretched between the fixedly ears or side handles of a utensil 21,22 of lifting speed reducer 22, and by the second through hole and two the first through hole contrapositions.
(3) bearing pin 31 inserted to the first through hole of the fixing ears or side handles of a utensil 21,22 and be arranged in the rigid enclosure 33 of the second through hole, bearing pin 31 and rigid enclosure 33 are interference fits, and bearing pin 31 needs cold charge.
(4) swelling linking sleeve 32 is installed on to bearing pin 31 from the two ends of bearing pin 31 and fixedly between the first through hole of the ears or side handles of a utensil 21,22, and regulates swelling linking sleeve 32 to carry out swelling.
In other embodiments, if monaural 11 and the fixedly 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 gap, prevent that lifting speed reducer from moving axially.
The present invention compared with prior art, contact between lifting speed reducer 2 and revolving dial 1 is tightr, guaranteed that lifting speed reducer can not move axially, can prevent reductor shake, extend 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.
Although described the present invention with reference to several exemplary embodiments, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because can specifically implementing in a variety of forms, the present invention do not depart from spirit of the present invention or essence, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claims, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be claims and contain.
