Description

Self-withdraw traction hitch for motor vehicle

The utility model relates on the automotive field, and it particularly is used in, and self-propelled vehicle sink, a kind of tool-type device that carries with car on the saving oneself of wheel slip.

Be everlasting self-propelled vehicle day and speed on the highway, on the highway of China, car (self-propelled vehicle, unpowered vehicle) mixed flow, the rugged urban and rural highway of traffic is arranged, the muddy complicated highway section of relocating is arranged, the self-propelled vehicle hedging, intersection allows car narrow road tune etc. often make vehicle hyposulculus or sunken car accidentally, and wheel slip can not in time sail out of the scene.

Common way can only be to push up with jack by the navigating mate and the personnel of riding, and removes the stone pad, perhaps please draw and ask the crane relief to solve by other people vehicle.By causing obstruction, allow vehicular traffic waste time thus,, normally make consequent danger and economic loss increasing because of can not in time removing the fault vehicle to site traffic.

" automobile safety anchor " of application can only be to implement under the dynamic and failure-free situation of transmission system of vehicle self before me, otherwise can only make in dangerous car and reinforce the unpowered function of saving oneself of shortage, broken line will be by hand also inconvenience considerably, existing these problems can be solved on the utility model.

The utility model is in order to overcome the above problems, adopt the method for a kind of stay cord Pan Bi, the mode of utilizing the power traction of self to extricate oneself by dynamic self-propelled vehicle, or motorless self-propelled vehicle utilizes hand wire-shrinking disk---the mode torsion line of chain block reduces the distance dangerous car is escaped danger, and vehicle in danger is reinforced and the expansion that avoids damage.

The purpose of this utility model is to realize like this, the self-propelled vehicle hauling hook of extricating oneself is in running order, bundle is at solid ground, the hillside, on crack of stone and the stub (location of loosening the soil can be squeezed into two reinforcing drill rods (attached 2) that loosen the soil in the earth of ox-horn claw the inside), advance this device when favourable of self-propelled vehicle is pricked front at self-propelled vehicle, fall favourable behind the self-propelled vehicle then with this device bundle back, put in the first speed advances, back reversal of the natural order of things reverse gear, allow steel wire around and shorten, making extricates oneself reaches and saves oneself, if vehicle falls into deeply excessively, perhaps drive-system has run out of steam, the self-propelled vehicle hauling hook of extricating oneself is put well by the front mode, wind is packed into the unidirectional safety plug that sets right on the drum gear, shake wire-shrinking disk, if stressed too big (loaded vehicle) shakes motionless, wind changed add on the powershift gear, adding powershift gear is 1/4th sizes of drum gear, and stressed also have only 1/4th, makes the vehicle that runs out of steam can reach the purpose of saving oneself.

The utility model need not be implemented under the situation that the change of any parts is in addition arranged on the former car, and pull resistance can be made some kinds of products more than to 20 tonne according to vehicle tonnage difference, and is simple in structure, and it is convenient to operate, carry, take care of.This device self has unpowered to motor-driven locomotive and transmission system does not have other requirement, compare with the jack on the market with other draw gear of extricating oneself that having extricates oneself and save oneself, reinforce insurance, the hand multiple function of saving oneself and escaping danger and time saving and energy saving simple and reliable advantage easily.

Concrete structure of the present utility model is provided by its accompanying drawing of following embodiment.

Accompanying drawing 1 is according to the extricate oneself view of hauling hook device of the self-propelled vehicle that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises a draw bar (1), a tri-claw disk (2), three ox-horn claws (4), on three equal positions such as grade of tri-claw disk green (among the figure not label), a fixing threaded hole (3) is arranged respectively, six movable pin-and-holes (18), three removable pins (19) are hung on draw bar (1), a threaded hole of steel of draw bar front end (5), a fixing screw (6), a unidirectional safety plug (7), a hand wheel (8) and two bobbin loaders (9), one adds powershift gear (10), a drum gear (11), two handles (12), a broken line pin (13) and a wire-shrinking disk (14) are supporting, and the two ends of a steel wire (15) fixedly are the hand with extended arm of this device with two wheel steel hooks (16) with two steel wire chucks (17).

Concrete principle of work is implemented thus, this device is sleeved on together by the same tri-claw disk in lower end (2) of draw bar (1), three ox-horn claws (4) are separately fixed in three all locational fixing threaded holes such as grade (3) of the tri-claw disk of tri-claw disk (2) green (among the figure not label), unidirectional safety plug (7) and add powershift gear (10) drum gear (11) handle (12) broken line pin (13) and the same bobbin loader of wire-shrinking disk (14) (9) fits together and be fixed on check screw (6) top of draw bar (1).Steel wire (15) passes two ends, threaded hole of steel (5) back and is connected with steel wire chuck (17) with wheel steel hook (16), and movable pin-and-hole (18) is that removable pin (19) is when working and the necessary workpiece during folding.During operation ox-horn claw (4) is launched (operating angle of ox-horn claw expansion is between 110 °～130 °), hang movable pin-and-hole (18) the inside that the removable pin (19) on draw bar (1) inserts " central ", and insure with spring cotter (not drawing among the figure), steel wire (15) is pulled out (steel wire among the figure (15) do not scratch into wire-shrinking disk (14) in) wheel steel hook (16) at two ends is hung in the steel ring hole in the middle of self-propelled vehicle drive wheel two steel rings (not drawing among the figure) from wire-shrinking disk (14), the self-propelled vehicle of single tire needs install additional single tire clamping plate (attached 1) and uses on the tire screw of tire outside.Loosen the soil with two and reinforce steel poles (attached 2) and squeeze in the earth and reinforce in the location of loosening the soil, the extricate oneself ox-horn claw (4) of hauling hook of self-propelled vehicle is penetrated in the drill rod earth in front, or on the firm object in sturdy ground and utilize the power of vehicle self to save oneself or the method for hand traction escape danger vehicle to sail out of the scene.

Pack up: removable pin (19) is pulled out ox-horn claw (4) is received cover, removable pin (19) is injected movable pin-and-hole (18) lining of " outside ", unidirectional safety plug pulled outward reverse 180 ° and put into, unidirectional safety plug front end square plays the location, the centre has spring (not drawing among the figure) to play return voluntarily, take turns to the equidirectional rocking-turn of unidirectional safety plug hand, make steel wire be subjected to the reflexed effect of broken line pin (13) that steel wire (15) is scratched in the middle of the wire-shrinking disk (14), become collapsible hauling hook.Wire-shrinking disk (14) can be made semiclosed or closed.

Claims (2)
