Description

Vehicle hard connects tractor

A kind of hard connection tractor, particularly vehicle hard connect tractor.

Having now a kind of is to adopt the rope traction self-propelled vehicle, is the mode of traction that is flexible coupling, and its shortcoming is: rope is long, influences traffic and easily causes traffic accident; Rope is short, is pulled car rear-end collision easily takes place, and another kind is to adopt long traction draw bar traction machine motor-car, is the hard mode of traction that connects, and its shortcoming is: length can not be regulated, and is not easy to carry with car.

It is a kind of simple in structure that the purpose of this utility model is to provide, and drawing length is adjustable, and is collapsible, is convenient to carry with car, safe in utilization, and the failure-free vehicle hard connects tractor.

The purpose of this utility model is realized by following technical scheme: a kind of vehicle hard connects tractor, it comprises sleeve pipe, front and back ends at sleeve pipe is provided with hauling hook 3, steel wire cable 2, its special character is sleeve pipe by prosthomere sleeve pipe 1, intermediate casing 5, deutomerite sleeve pipe 6, is provided with fittings body 7 and forms between prosthomere sleeve pipe 1, intermediate casing 5, deutomerite sleeve pipe 6, in prosthomere sleeve pipe 1 capstan winch is set, capstan winch is by reel 8, and drum shaft 15 is formed; In prosthomere sleeve pipe 1, ratchet wheel backstop is set, ratchet wheel backstop by with the fixing ratchet 9 of reel 8, the ratchet 10 that is meshed with ratchet 9, the support spring 11 of ratchet 10 is formed, steel wire cable 2 places in the sleeve pipe, and an end of steel wire cable 2 is connected with reel 8, and other end rear towing hook 3 connects.

Set up adjusting sleeve 4, adjusting sleeve 4 places between the fittings body 7 and fittings body 7 of sleeve pipe.One of them fittings body 7 is provided with opening.

Vehicle hard of the present utility model connects tractor, because sleeve pipe adopts sectional construction, steel wire cable is long and short adjustable, therefore, can realize the hard connection traction of self-propelled vehicle, and hauling distance is adjustable, sleeve pipe is collapsible, have simple in structurely, be convenient to carry, advantage such as safe in utilization, reliable with car.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 connects the retractor structures cross-sectional schematic for vehicle hard.

Fig. 2 is an A-A generalized section among Fig. 1.

Fig. 3 is a B-B cross-sectional schematic among Fig. 1.

Fig. 4 is connector 7 structural representations of band opening.

With reference to Fig. 1-4, sleeve pipe is provided with fittings body 7 and is formed by prosthomere sleeve pipe 1, intermediate casing 5, deutomerite sleeve pipe 6 between prosthomere sleeve pipe 1, intermediate casing 5, deutomerite sleeve pipe 6.When sleeve pipe needs length to transfer length, between two fittings bodies 7 of sleeve pipe, set up adjusting sleeve 4, when setting up adjusting sleeve 4, the connector 7 of one end has opening, and the cross section of adjusting sleeve 4 is the opening ring-type, and steel rope enters in the pipe from the opening part of regulating sleeve 4.The sleeve pipe front and back end is provided with hauling hook 3, wherein front haulage hook 3 is connected with sleeve pipe prosthomere sleeve pipe 1, rear towing hook 3 is connected with steel wire cable 2, and the opening part of hauling hook 3 is provided with the lock hook catch 12 of retracing spring 13 supportings, and lock hook catch 12 is connected with hauling hook 3 by bearing pin with retracing spring 13.In prosthomere sleeve pipe 1 capstan winch is set, capstan winch is made up of reel 8, drum shaft 15.Reel 8 is loaded on the prosthomere sleeve pipe 1 by drum shaft 15, in prosthomere sleeve pipe 1 ratchet wheel backstop is set, ratchet wheel backstop by with the fixing ratchet 9 of reel 8, the ratchet 10 that is meshed with ratchet 9, the support spring 11 that is placed on 10 on the ratchet is formed.Steel wire cable 2 places in the sleeve pipe, and an end of rope 2 is connected with reel 8, and the other end is connected with rear towing hook 3, and vehicle hard connects tractor can be used separately, when hauling distance is big, can adopts two or more to connect lengthening and use.

During use, two hauling hooks 3 respectively with tractor truck, being pulled car connects, cw shakes handgrip 14, capstan winch is around in steel wire cable 2 on the reel 8, after every joint sleeve pipe of sleeve pipe became rigid body, the ratchet 10 of ratchet wheel backstop made tractor truck and is pulled car maintenance spacing and realizes being connected firmly traction under the effect of support spring 11.Traction finishes, and stirs ratchet 10, and compression support spring 11 is thrown off ratchet 10 and ratchet 9, unclasps steel wire cable 2, and hauling hook 3 and two cars are thrown off, and makes sleeve pipe folding, carries with car.
