Description
Technical field
The invention belongs to roadside assistance fields, and in particular to a kind of breakdown trailer draft gear.
Background technology
Roadside assistance refers to trap for automobile emergency relief, and the services such as live light maintenance are provided for failure car owner.With domestic automobile
The continuous development in market, existing larger, compact car repair company and service company have all been proposed the automobile rescue clothes of oneself
Business, if car owner encounters failure, such as cannot start suddenly, it is flame-out after can not start, not have in oil, out of power or even road and blow out
Deng, so that it may to contact the shops 4S or nearest automobile rescue service company, seek help to the automobile rescue technical staff of profession, they
It can inquire and judge the general problem of automobile, then rush for scene and succoured.Automobile rescue service includes：Oil is sent, charged, sent and change wheel
Tire, field failure exclusion, failure trailer etc..Wherein, failure trailer refers to providing breakdown trailer, and fault car is placed into rescue
On trailer, maintenace point is transported to by breakdown trailer.
Disabled vehicle is placed into the draft gear usually utilized on breakdown trailer on breakdown trailer, draft gear includes twisting
Disk is wound with traction rope in capstan winch, the free end of traction rope and disabled vehicle is fixed together, and passes through and rotates capstan winch so that leads
Messenger is tightened, and disabled vehicle is drawn on breakdown trailer.Above-mentioned draft gear there are the problem of have：If disabled vehicle is heavier, directly
Connecing that draw required power using traction rope larger, traction rope is easy disconnected, and traction rope is easy to shake in distraction procedure, to
Cause the further damage of disabled vehicle.
Invention content
The purpose of the present invention is to provide a kind of breakdown trailer draft gears, to solve to draw disabled vehicle to rescue to drag
The problem of disabled vehicle further damages is be easy to cause during on vehicle.
In order to achieve the above objectives, base case of the invention is：Breakdown trailer draft gear, including trailer ontology, institute
It includes the wagon box being slidably connected on trailer ontology to state trailer ontology, and wagon box bottom surface, which is fixedly connected, to be useful for gliding on driving wagon box
Dynamic first hydraulic cylinder；Crawler belt group and the engine for driving crawler belt group are equipped in wagon box, crawler belt group includes being arranged on vehicle
Struggle against the first crawler belt and the second crawler belt of both sides, the first crawler belt and the second crawler belt include the driving wheel set gradually from left to right,
Tensioning wheel and driven wheel, are additionally provided with connecting rod in wagon box, and connecting rod both ends are rotatably connected on tensioning wheel and driven wheel respectively
End face circle centre position, connecting rod are hinged on close to one end of tensioning wheel on wagon box inner wall, include stretch section in the middle part of connecting rod；Wagon box bottom
Face slidably connects slide plate, and wagon box bottom surface, which is fixedly connected, is useful for the second hydraulic cylinder that driving slide plate slides laterally, and slide plate is close
One end end of driven wheel is fixedly connected with limiting plate.
The operation principle of this base case is：
Two connecting rods are rotated simultaneously, and connecting rod drives driven wheel to be rotated around tensioning wheel, and the first crawler belt and the second crawler belt lean on
One end rotation of nearly driven wheel.When rotating forward connecting rod, the first crawler belt and the second crawler belt are rotated down close to one end of driven wheel, are made
It obtains the first crawler belt and the second crawler belt is tilted down close to one end of driven wheel and landed, be transported in crawler belt group convenient for disabled vehicle.Instead
When turning connecting rod, the first crawler belt and the second crawler belt are rotated up close to one end of driven wheel so that the first crawler belt and the second crawler belt
It is flipped up close to one end of driven wheel, blocks the rear end of wagon box, disabled vehicle is avoided to be slid out of wagon box.
Second hydraulic cylinder drives slide plate to be slided to close to disabled vehicle direction, below slide plate slides to failure chassis, first
Driven by Hydraulic Cylinder wagon box moves upwards, and slide plate moves upwardly together with wagon box and holds up disabled vehicle, and second hydraulic cylinder drives slide plate
It withdraws, disabled vehicle is withdrawn with slide plate.Disabled vehicle front-wheel is first and the contact of crawler belt group, crawler belt group play transmission, failure to disabled vehicle
Chinese herbaceous peony wheel end is tilted with the transmission of crawler belt group, and the limiting plate on slide plate is slided after avoiding disabled vehicle, until the trailing wheel end of disabled vehicle
Also it is contacted with crawler belt group, disabled vehicle is entirely located in crawler belt group, and the rubbing action between crawler belt group and disabled vehicle drives disabled vehicle
It is transmitted into wagon box, until when disabled vehicle is entirely located between driving wheel and tensioning wheel, closes crawler belt group.
The advantageous effect of this base case is：
1, conveyer belt to be compared, crawler belt group is set in the present apparatus, on the one hand, tractive force when crawler-tread is bigger than conveyer belt,
The general weight of disabled vehicle is larger, is more convenient transmission, and the load-bearing capacity of crawler belt is got well than conveyer belt；On the other hand, track surface
Rough, the friction bigger between disabled vehicle avoids in transmit process and transportational process, disabled vehicle shakes on crawler belt.
2, connecting rod is set, connecting rod rotation can drive the first crawler belt, the second crawler belt to be swung close to one end of driven wheel.
First crawler belt and the second crawler belt are tilted down close to one end of driven wheel when landing, and are transported in crawler belt group convenient for disabled vehicle；The
When one crawler belt and the second crawler belt are flipped up close to one end of driven wheel, the rear end of wagon box is blocked, avoids disabled vehicle out of wagon box
It slides.
3, slide plate is set, slide plate can slide under failure chassis, integrally be slid up in second hydraulic cylinder driving wagon box
When dynamic, slide plate holds up disabled vehicle upwards so that the front-wheel of disabled vehicle tilts, it is easier to be sent in crawler belt group, and limiting plate with
Slide plate moves upwards, and can block the rear end of disabled vehicle, and slide plate can drive disabled vehicle to be transported to close to crawler belt group direction when withdrawing
It is dynamic.
Further, slide plate both sides have been fixedly connected with several industrial suckers.After slide plate is inserted into below failure chassis, utilize
Slide plate and disabled vehicle are fixed together by industrial sucker, can be to avoid disabled vehicle in slide plate before disabled vehicle contact track group
Upper shaking.
Further, the first crawler belt and the second crawler belt are metal pin hinge type crawler belt.Compared to metal-rubber hinge type crawler belt,
Metal pin hinge type crawler belt cost is lower, and in the present apparatus, and crawler belt group is only used for transmission disabled vehicle, and is not applied to walk,
Therefore, metal pin hinge type crawler belt can meet the requirement of the present apparatus.
Further, the first crawler belt and the second crawler belt are steel tracks.Compared to rubber belt track, the service life of steel tracks
It is longer, and in the present apparatus, the weight of disabled vehicle is larger, steel tracks can meet the load bearing demand in the present apparatus.
Further, the outer side shield positioned at crawler belt group is fixedly connected in wagon box.It prevents in transportational process, disabled vehicle exists
Double swerve in wagon box is fallen from crawler belt group.
