Description
Technical field
The present invention relates to a kind of folding breakdown trailer of belt lifting mechanism.
Background technology
Breakdown trailer be used for traction due to failure, accident and can not normally travel vehicle, special obstacles removing car volume is big, complex structure, special train is special, can only perform trailer task, bad adaptability, acquisition cost and use cost are all very high, it is impossible to adapt to the trailer demand of the less Automobile Service Factory of scale.
The content of the invention
The technical problem to be solved in the present invention is：Accident vehicle can be loaded by providing a kind of folding breakdown trailer, common vehicle can turn into the breakdown lorry with trailer function by simple transformation, and need not carrying springboard.
The technical solution adopted for the present invention to solve the technical problems is：A kind of folding breakdown trailer of belt lifting mechanism, including girder, folded beam, crossbeam, wheel support and trailer wheels, the head end of girder is provided with the connector being connected for the tow ball with breakdown lorry, the other end of girder and one end of folded beam are hinged by the main beam pivot part and folded beam hinge member being separately fixed on girder and folded beam, the folded beam gas spring for promoting folded beam expansion is set between girder and folded beam, the both sides of folded beam have the crossbeam being hinged with folded beam, wheel support has two, two wheel supports are arranged on crossbeam, and it is located at the both sides of folded beam respectively, trailer wheels are arranged in wheel support by mechanical jack elevating mechanism.
Further limit, the crossbeam gas spring with controlling switch that driving crossbeam is opened is installed on folded beam, the telescopic end of crossbeam gas spring is connected by folding connecting rod with crossbeam, and the controlling switch of crossbeam gas spring controls opening opportunity by the cam being fixed on main beam pivot part.
Further limit, wheel support is slippingly arranged on crossbeam, there is the connecting rod rack stretched out to folded beam both sides on folded beam, the wheel support connecting rod slid between wheel support and connecting rod rack by driven wheel support on crossbeam is connected, one end of wheel support connecting rod is hinged with wheel support, and the other end of wheel support connecting rod is hinged with connecting rod rack.
The beneficial effects of the invention are as follows：This trailer can be retractable in the common vehicle of conventional size completely, larger repacking need not be carried out to vehicle, pass through mechanical jack elevating mechanism lifting wheel support, accident, fault car are directly drawn by capstan winch to wheel support, without using springboard, the part for needing to carry is reduced.

Embodiment
Such as Fig. 1, 2, 3, 4, shown in 5 and 6, a kind of folding breakdown trailer of belt lifting mechanism, including girder 3, folded beam 4, crossbeam 5, take turns support 6 and trailer wheels 7, the head end of girder 3 is provided with the connector 8 being connected for the tow ball with breakdown lorry, the other end of girder and one end of folded beam are hinged by the main beam pivot part and folded beam hinge member being separately fixed on girder and folded beam, the folded beam gas spring 9 for promoting folded beam 4 to deploy is set between girder 3 and folded beam 4, the both sides of folded beam 4 have the crossbeam 5 being hinged with folded beam 4, wheel support 6 has two, two wheel supports 6 are arranged on crossbeam 5, and it is located at the both sides of folded beam 4 respectively, trailer wheels 13 are arranged in wheel support 6 by mechanical jack elevating mechanism 23.Except scissor-like jack elevating mechanism is used in accompanying drawing, other mechanical jack elevating mechanisms 23 of the prior art can also be used.
The crossbeam gas spring 19 with controlling switch that driving crossbeam 5 is opened is installed on folded beam 4, the telescopic end of crossbeam gas spring 19 is connected by folding connecting rod 14 with crossbeam 5, and the controlling switch of crossbeam gas spring 19 controls opening opportunity by the cam 20 being fixed on main beam pivot part.Folded beam gas spring can also be the gas spring with controlling switch, and girder can keep folded state by folded beam gas spring after folding.The shape of cam ensures that the controlling switch of crossbeam gas spring 19 when crossbeam is folded completely is in release conditions, and crossbeam can keep folded state by crossbeam gas spring 19.
Support 6 is taken turns slippingly to be arranged on crossbeam 5, there is the connecting rod rack 17 stretched out to the both sides of folded beam 4 on folded beam 4, the wheel support connecting rod 18 slid between wheel support 6 and connecting rod rack 17 by driven wheel support 6 on crossbeam 5 is connected, one end of wheel support connecting rod 18 is hinged with wheel support 6, and the other end of wheel support connecting rod 18 is hinged with connecting rod rack 17.
Release process is as follows：
Folded beam 4 is slowly opened in the presence of folded beam gas spring 9；Folded beam 4 open to a certain degree when, the cam 20 on main beam pivot part presses the controlling switch of sill gas spring 19, crossbeam gas spring 19 is worked, and opens crossbeam 5.Wheel support is fallen by mechanical jack elevating mechanism 23 so that accident, fault car can be directly drawn to wheel support by capstan winch, then rise wheel support, complete whole trailer loader process.
The process of folding trailer unit is as follows：
It is artificial to fold crossbeam, and overcome the active force of folded beam gas spring 9 to fold folded beam 4 and girder 3, when folded beam 4 and girder 3, crossbeam are folded in place completely, the controlling switch of crossbeam gas spring 19 is in release conditions, make the not flexible of crossbeam gas spring 19, folded state between folded beam 4 and girder 3 can be kept by using the folded beam gas spring with controlling switch, can also keep their folded state by modes such as lock, rope bindings.
