Abstract
The utility model relates to a folding rescue trailer unfolded by air springs. The folding rescue trailer unfolded by the air spring comprises a main beam, a folding beam, crossbeams, wheel supports and trailer wheels; a folding bean air spring is arranged between the main beam and the folding beam; the wheel supports are arranged on the crossbeams; the trailer wheels are arranged on the wheel supports; a crossbeam air spring used for driving and opening the crossbeams and provided with a control switch is arranged on the folding beam; a telescopic end of the crossbeam air spring is connected with the crossbeams by folding connection rods; the control switch of the crossbeam air spring controls the opening moment by a cam fixed on a main beam hinging part. The folding rescue trailer unfolded by the air springs has the beneficial effects that the trailer can be fully contained in a common vehicle with a regular size, and the vehicle does not need larger refitting; the crossbeam air spring with the control switch can be used for controlling the opening moment of the crossbeams, the crossbeams can only be unfolded in the unfolding process of the folding beam, and the folding state of the crossbeams does not need to be kept by an extra locking part.
Description
Technical field
The utility model relates to a kind of folding breakdown trailer launching by air bellow.
Background technology
The vehicle that breakdown trailer cannot normally travel due to fault, accident for traction, special-purpose wrecker volume is large, complex structure, special train is special-purpose, can only carry out trailer task, bad adaptability, acquisition cost and use cost are all very high, can not adapt to the trailer demand of the Automobile Service Factory that scale is less.
Utility model content
The technical problems to be solved in the utility model is: a kind of folding breakdown trailer launching by air bellow is provided, common vehicle can become the breakdown lorry with trailer function through simple transformation, and can make crossbeam only in folded beam expansion process, can launch.
The utility model solves the technical scheme that its technical matters adopts: a kind of folding breakdown trailer launching by air bellow, comprise girder, folded beam, crossbeam, wheel holder and trailer wheels, the head end of girder is provided with the connector for being connected with the tow ball of breakdown lorry, the other end of girder and one end of folded beam are hinged by the girder articulated section and the folded beam articulated section that are separately fixed on girder and folded beam, between girder and folded beam, arrange and promote the folded beam gas spring that folded beam launches, the both sides of folded beam have the crossbeam hinged with folded beam, wheel holder has two, two wheel holders are arranged on crossbeam, and lay respectively at the both sides of folded beam, trailer wheels is arranged in wheel holder, the crossbeam gas spring with master cock that drives crossbeam to open is installed on folded beam, the telescopic end of crossbeam gas spring is connected with crossbeam by folding connecting rod, the master cock of crossbeam gas spring is opened opportunity by the cam control being fixed on girder articulated section.
Further limit, wheel holder is arranged on crossbeam slippingly, on folded beam, there is the connecting rod rack stretching out to folded beam both sides, between wheel holder and connecting rod rack, by driven wheel holder wheel holder connecting rod of slippage on crossbeam, connect, one end of wheel holder connecting rod is hinged with wheel holder, and the other end and the connecting rod rack of wheel holder connecting rod are hinged.
The beneficial effects of the utility model are: this trailer completely folding and unfolding, in the common vehicle of conventional size, does not need vehicle to carry out larger repacking;
Crossbeam gas spring with master cock can be controlled the opportunity that crossbeam is opened, and crossbeam only can launch in folded beam expansion process, and does not need extra Lock Part to keep the folded state of crossbeam.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the structural representation after the utility model launches completely;
Fig. 2 is crossbeam expansion process schematic diagram of the present utility model;
Fig. 3 is that cam of the present utility model is by the schematic diagram of the master cock of cross sill gas spring;
Fig. 4 is the schematic diagram that cam of the present utility model discharges the master cock of crossbeam gas spring;
In figure, 3. girder, 4. folded beam, 5. crossbeam, 6. takes turns holder, 7. trailer wheels, 8. connector, 9. folded beam gas spring, 14. folding connecting rods, 17. connecting rod racks, 18. take turns holder connecting rod, 19. crossbeam gas springs, 20. cams.
The specific embodiment
As Fig. 1, 2, shown in 3 and 4, a kind of folding breakdown trailer launching by air bellow, comprise girder 3, folded beam 4, crossbeam 5, wheel holder 6 and trailer wheels 7, the head end of girder 3 is provided with the connector 8 for being connected with the tow ball of breakdown lorry, the other end of girder and one end of folded beam are hinged by the girder articulated section and the folded beam articulated section that are separately fixed on girder and folded beam, between girder 3 and folded beam 4, arrange and promote the folded beam gas spring 9 that folded beam 4 launches, the both sides of folded beam 4 have the crossbeam 5 hinged with folded beam 4, wheel holder 6 has two, two wheel holders 6 are arranged on crossbeam 5, and lay respectively at the both sides of folded beam 4, trailer wheels 7 is arranged in wheel holder 6.
The crossbeam gas spring 19 with master cock that drives crossbeam 5 to open is installed on folded beam 4, the telescopic end of crossbeam gas spring 19 is connected with crossbeam 5 by folding connecting rod 14, and the master cock of crossbeam gas spring 19 is opened opportunity by cam 20 controls that are fixed on girder articulated section.Folded beam gas spring can be also the gas spring with master cock, and girder can keep folded state by folded beam gas spring after folding.When the shape assurance crossbeam of boss folds completely, the master cock of crossbeam gas spring 19 is in release position, and crossbeam can keep folded states by crossbeam gas spring 19.
Wheel holder 6 is arranged on crossbeam 5 slippingly, on folded beam 4, there is the connecting rod rack 17 stretching out to folded beam 4 both sides, wheel holder connecting rod 18 by driven wheel holder 6 slippage on crossbeam 5 between wheel holder 6 and connecting rod rack 17 connects, one end of wheel holder connecting rod 18 is hinged with wheel holder 6, and the other end and the connecting rod rack 17 of wheel holder connecting rod 18 are hinged.
Dispose procedure is as follows:
Folded beam 4 is slowly opened under the effect of folded beam gas spring 9; When folded beam 4 opens to a certain degree, cam 20 on girder articulated section is pressed the master cock of cross sill gas spring 19, make 19 work of crossbeam gas spring, open crossbeam 5, connector 8 is directly buckled on tow ball, in wheel holder 6, set up springboard, accident, fault vehicle, by the upper wheel holder 6 of capstan winch 2 traction, complete whole trailer loading process.
The process of folding trailer unit is as follows:
Artificial folding crossbeam, and the folding folded beam 4 of the application force that overcomes folded beam gas spring 9 and girder 3, at folded beam 4 and girder 3, crossbeam completely during folding putting in place, the master cock of crossbeam gas spring 19 is in release position, make the 19 not flexibles of crossbeam gas spring, folded state between folded beam 4 and girder 3 can keep by the folded beam gas spring with master cock by employing, also can keep their folded state by modes such as snap close, rope bindings.
