Imitate the needs of production.
Detailed description of the invention
Fig. 1 is a kind of double drive crawler overall structure diagram described in the utility model；
Fig. 2 is a kind of double drive crawler side view described in the utility model；
In figure:
1 crawling traction wheel, 2 compression cylinder, 3 crawler belt, 4 fixed plate, 5 live roller
6 expansion tightening wheel, 7 motor reducer
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
A kind of double drive crawler provided by the utility model, the present apparatus include rack and upper and lower two tractions structure
Part, upper and lower two driving components are fixed on the rack, and upper driving component is by crawling traction wheel 1, crawler belt 3, fixed plate 4, expansion tightening wheel
6, motor reducer 7 is constituted.Wherein, crawling traction wheel 1 is driven by motor reducer 7, and entirely upper driving component is surround by crawler belt 3
Crawling traction wheel 1, expansion tightening wheel 6, fixed plate 4 are fixed, and expansion tightening wheel 6 is horizontally moveable and location structure, and upper driving component passes through
Crawler belt is dragged around crawling traction wheel 1, expansion tightening wheel 6, and expansion tightening wheel 6 is shrinkable expansion member, lower traction element and upper traction
Modular construction is identical, and each component is ipsilateral in symmetrical up and down in rack.
Preferably, fixed plate 4 is connected with cylinder 2, and cylinder 2 guides fixed plate 4 to carry out vertical direction and moves up and down, expansion tightening wheel
6, which are connected with cylinder or motor, can drive expansion tightening wheel 6 to carry out horizontal direction movement, and further, fixed plate 4 is set towards crawler belt side
It is equipped with live roller 5, when cylinder rod drives fixed plate 4 to move down, the live roller 5 above fixed plate 4 compresses crawler belt 3,
Upper and lower driving component moves toward one another, so that cable is clamped, when crawler belt is mobile, under frictional force effect forward by cable pulling,
It realizes and the traction of cable is conveyed, conversely, cylinder rod is withdrawn when cylinder discharges air pressure, crawler belt is no longer compacted, so as to will be electric
Cable is pulled out from two root skin interbands；And expansion tightening wheel 6, cylinder or motor effect under expansion tightening wheel 6 carry out it is a certain amount of move left and right,
Purpose is: when machine run, expansion tightening wheel 6 tenses crawler belt 3 to far from the movement of 1 side of crawling traction wheel, so that it is guaranteed that traction structure
Part is integrally to the frictional force of cable；And when to replacement crawler belt 3, expansion tightening wheel 6 is to close to the return of 1 side of crawling traction wheel, 3 quilt of crawler belt
It unclamps, so as to which by track removal, further, motor reducer 7 and crawling traction wheel 1 are located at rack two sides, motor
Speed reducer 7 by motor shaft pass through rack aperture be directly connected to 1 center axial trough of crawling traction wheel driving rotation, lower driving component with
Upper driving component structure and movement mechanism are identical.
Preferably, motor reducer 7 uses bi-motor cross-compound arrangement, the crawling traction of lower driving component and upper driving component
Wheel is driven using the bi-motor dual-axle motor speed reducer.
Wherein, 4 quantity of fixed plate is preferably arranged to 6 according to track length and driving component overall width, each
5 quantity of live roller in fixed plate 4 is preferably arranged to 6 according to 4 width adjustment of fixed plate.Be machined on live roller 5 with
The serrate slot that crawler belt 3 cooperates.
The utility model is mainly characterized by, and is eliminated the transmission gear that existing caterpillar-tractor uses and is drivingly connected structure,
Crawler belt is innovatively directly driven respectively using two motor reducers, to eliminate the noise under conventional gears transmission, tooth
It is inconvenient for use to take turns the maintenance such as oil, meanwhile, the structure of equipment is simpler, conventional track dragger due to there are motor, speed reducer,
Multiple drive stations such as gear, are connected and fixed, and propose very high request to rack manufacture.The present invention need to only guarantee crawling traction
Machining accuracy at wheel, and number of parts is less, installation manufacture maintenance cost is lower.In control mode, using upper and lower
The control mode of crawler belt " independence+combination ", it may be assumed that lower crawler belt uses speed control mode, tracks line speed；Upper shoe motor can
Setting band uses torque mode, tracks lower crawler track speeds, realizes the dynamic synchronization of crawler belt up and down.
Although the utility model is disclosed as above with preferred embodiment, so it is not intended to limit the utility model, any
