One end of the other end of second support arm and the 3rd support arm is hinged, the 3rd support arm and the described second support
The be hinged one end of arm is fixed on the crossbeam simultaneously, and the other end of the 3rd support arm is articulated with second fixed seat
On, described hydraulic jack one end is articulated with second fixed seat, and the other end is then articulated with first support arm and described
Second support arm is hinged place, and the crossbeam both ends are respectively hinged with a bearing block, relative institute on each bearing block
State crossbeam and be symmetrically arranged with two directive wheels, the drag link both ends are individually fixed on two bearing blocks and parallel
In the crossbeam.
The beneficial effects of the utility model are：The unpowered bogie component parts of the combined sweeper is few, knot
Structure is simple, passes through the flexible rotation for directly or indirectly driving the first support arm, the second support arm and the 3rd support arm of hydraulic jack
Turning, and then lift and put down sleeve mechanism so that operation is more reliable and more stable, meanwhile, the design of drag link can ensure that vehicle is suitable
The track that profit passes through 25m sweeps.
Brief description of the drawings
Fig. 1 show the front view of the unpowered bogie of combined sweeper in the utility model.
Fig. 2 show the top view of the unpowered bogie of combined sweeper in the utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing, illustrated embodiment is served only for explaining the utility model,
It is not intended to limit the scope of the utility model.
It is a kind of unpowered bogie of combined sweeper provided by the utility model as depicted in figs. 1 and 2, it is fixed
On vehicle frame 11, including the first fixed seat 1, the second fixed seat 2, the first support arm 3, the second support arm 4, the 3rd support arm 5,
Hydraulic jack 6, crossbeam 7, bearing block 8, directive wheel 9 and drag link 10.
Arrying main body of the vehicle frame 11 as the unpowered bogie of the combined sweeper, play fixed the whole series
The effect of mechanism, first fixed seat 1 and second fixed seat 2 are arranged side by side on the vehicle frame 11, for fixing it
His part.First support arm 3, second support arm 4 and the 3rd support arm 5 are the critical pieces that action is transmitted,
Described one end of first support arm 3 is articulated with first fixed seat 1, can be rotated around first fixed seat 1, the other end then with
One end of second support arm 4 is hinged, and both can relatively rotate, the other end of second support arm 4 with described 3rd
One end of brace 5 is hinged, and both can also relatively rotate, and the 3rd support arm 5 and one end that second support arm 4 is hinged are same
When be fixed on the crossbeam 7, the other end of the 3rd support arm 5 is articulated with second fixed seat 2, can be around described
Two fixed seats 2 rotate.Driving main body of the hydraulic jack 6 as sleeve mechanism, described one end of hydraulic jack 6 are articulated with described
In second fixed seat 2, the other end is then articulated with first support arm 3 and second support arm 4 is hinged place.The liquid
Flexible can drive of compressing cylinder 6 turns corresponding to first support arm 3, second support arm 4 and the 3rd support arm 5
It is dynamic, and then the expanding-contracting action of the hydraulic jack 6 is converted into first support arm 3, second support arm 4 and described the
The spinning movement of three support arms 5.One end that second support arm 4 and the 3rd support arm 5 are hinged is fixed on described
On crossbeam 7, thus, the action of first support arm 3, second support arm 4 and the 3rd support arm 5 can drive described
The raising and lowering of crossbeam 7.The both ends of crossbeam 7 are respectively hinged with a bearing block 8, and two bearing blocks 8 are symmetrical arranged,
The bearing block 8 can carry out the swing of low-angle around the both ends of crossbeam 7, same during adapting to pass through on track small curve radius
The synchronism of the beat of directive wheel 9 of side two.Relatively described crossbeam 7 is respectively symmetrically connected with two on each bearing block 8
The individual directive wheel 9, specifically, the bearing block 8 and the directive wheel 9 pass through bearing and axis connection.10 liang of the drag link
End is individually fixed on two bearing blocks 8 and parallel to the crossbeam 7, to ensure that two bearing blocks 8 are being run over
Swing angle is the same in journey, it is ensured that driving safety, also may be such that vehicle passes through the track of 25m sweeps.Due to described
Bearing block 8, the directive wheel 9 and the drag link 10 are connected with each other and are finally secured on the crossbeam 7, therefore the crossbeam 7
Raising and lowering action can drive above-mentioned part raising and lowering together, finally realize the folding and unfolding of sleeve mechanism.
In order to ensure that the raising and lowering of sleeve mechanism is more steady and smooth, ensure that the stress of crossbeam 7 is more uniformly distributed,
The hydraulic jack 6, first support arm 3, the quantity of second support arm 4 and the 3rd support arm 5 are disposed as
Two, and four one-to-one corresponding are described according to being symmetricly set in after a set of three-link mechanism of connected mode described previously connection composition
Between vehicle frame 11 and the crossbeam 7, that is, there are two sets of three-link mechanisms while act on the both ends of the crossbeam 7, so that institute
State the stress of crossbeam 7 to be more uniformly distributed, the raising and lowering of sleeve mechanism also more steady and smooth.
The beneficial effects of the utility model are：The unpowered bogie component parts of the combined sweeper is few, knot
Structure is simple, passes through the flexible rotation for directly or indirectly driving the first support arm, the second support arm and the 3rd support arm of hydraulic jack
Turning, and then lift and put down sleeve mechanism so that operation is more reliable and more stable, meanwhile, the design of drag link can ensure that vehicle is suitable
The track that profit passes through 25m sweeps.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
