The folded plate mechanism comprises a secondary platform beam (1), a load platform (2), a tilt platform oil cylinder (6), a retractable platform oil cylinder (9), a retractable oil cylinder bracket (13), a secondary platform beam support (8), retractable square box assemblies (4), a spacing device (14) and hinge pieces (3 and 7); and the folded plate mechanism is characterized in that the load platform (2) is divided into a front section and a rear section at the rear part of the retractable oil cylinder bracket (13), the front section and the rear section are hinged with each other through the hinge piece (3), and the rear section adopts two bilaterally-symmetrical retractable square box assemblies (4).
Description
Technical field
The utility model belongs to the function combination mechanism of arteries of communication wrecker.
Background technology
Wrecker flap mechanism is one of function assembly set of wrecker, and its function is to be drawn on the loading platform by the inclined-plane that it forms dragging vehicle, implements the back bracket migration then.At present domestic wrecker flap mechanism be 8 ° of flap mechanisms (be flap extend backward and the back of contacting to earth formed with the ground angle be more than 8 °), this be since the length of the vehicle frame terrain clearance of wrecker and the extending part of loading platform all the normalisation typing determine.For example homemade KFM5072TQZ etc. is exactly this class wrecker.This angle can not satisfy different road conditions and the dissimilar needs of removing obstacles that dragged vehicle comprehensively, when especially being dragged the angle of attach of vehicle too small (as the low chassis sport car), if will be dragged vehicle to be drawn on the loading platform, its preceding face lower edge very easily touches on the formed inclined-plane of friction loading platform, so limited the Applicable scope of wrecker.
Summary of the invention
The purpose of this utility model is for the fixing wrecker of elongation behind vehicle terrain clearance and the loading flat-bed provides a kind of flap mechanism that can reduce to draw inclined-plane and ground angle to greatest extent, to adapt under different road conditions the back bracket to various vehicles.
The technical solution of the utility model relates to a kind of telescopic square chest type flap mechanism for achieving the above object, and this mechanism comprises platform auxiliary girder (1), loading platform (2), platform inclination oil cylinder (6), platform telescopic oil cylinder (9), platform auxiliary girder support cylinder (8), platform telescopic oil cylinder support (13), flexible square chest assembly (4) and inhibiting device (14) and hinged component (3) (7).The bottom of loading platform (2) is provided with platform auxiliary girder (1), and both are by emboss pit bearing fit interlocking longitudinally; Be equipped with platform inclination oil cylinder (6) between platform auxiliary girder (1) and the wrecker crossbeam (5), platform auxiliary girder (1) bottom is connected with the afterbody hinge of wrecker crossbeam (5) by hinged component (7); The below of platform auxiliary girder (1) is provided with auxiliary girder and supports (8); Loading platform (2) bottom is equipped with platform telescopic oil cylinder (9), is fixed on the platform telescopic oil cylinder support (13); Two joints before and after loading platform (2) resolves at the rear portion of platform telescopic oil cylinder support (13), internode is hinged by hinged component (3), and deutomerite is two symmetrical flexible square chest assemblies (4).Flexible square chest assembly (4) is made up of the flexible square chest (10) of the built-in wedge shape of flexible outer container, wedge shape stretch square chest (10) through slider roller (15) can be manually from the outer container that stretches pull extend and fix by locating plate (20) and alignment pin (19); The most advanced and sophisticated angle of the flexible square chest 10 of wedge shape is 5 °.
Compare with known technology, the utility model is improved to folding retractable square chest type structure with rigidity loading platform, be that the loading platform can be at the knuckle of hinge burst generation less than 180 °, so can be under the situation of elongation behind identical chassis frame height and the loading platform, reduce loading platform afterbody and ground-surface inclination minimum greatly, make and dragged vehicle to pull on the loading platform easily, avoid the situation with loading platform generation frictional impact, adapted to back bracket migration all kinds of vehicles.

The specific embodiment
Describe structure of the present utility model and principle of work in detail below in conjunction with accompanying drawing.
Between platform auxiliary girder (1) bottom and wrecker crossbeam (5), be provided with the platform inclination oil cylinder (6) of tendency.Platform auxiliary girder (1) is hinged with it with hinged component (7) at wrecker crossbeam (5) afterbody place.The bottom of loading platform (2) is provided with the interlocking of the vertical protruding beam bearing fit on the platform telescopic chute (12) and platform auxiliary girder (1) longitudinally, and platform telescopic chute (12) is provided with deep beam (11).Loading platform (2) is two joints before and after the rear positions of the platform telescopic oil cylinder support (13) of its setting resolves into, two internodes are hinged and be provided with inhibiting device (14) with hinged component (3), thereby make loading platform (2) folding less than 180 ° of joint before and after decomposition place can realize.
During work, it is solid earlier the flexible square chest (10) of wedge shape to be pulled out pin from flexible outer container, flexible platform auxiliary girder (1) the appendix goods platform (2) that makes by platform inclination oil cylinder (6) recedes along the rotation of the hinge-point (7) on the wrecker crossbeam (5) then, after the platform auxiliary girder supports (8) support ground, loading platform (2) longitudinal sliding motion is stretched out backward, at heeling condition lower tail kiss the earth, continue to add the degree of dip of large platform auxiliary girder (1) by platform inclination oil cylinder (6), the promptly flexible square chest (4) of deutomerite of loading platform (2) is reduced with ground-surface angle, until deutomerite (promptly flexible square chest) tiling ground, form the little inclined-plane of transition at 5 ° of angles.By the trailer coupling on the wrecker, will be dragged vehicle to guide on 5 ° the little inclined-plane, make and dragged the preceding of vehicle to face upward on the face, be drawn to again on the loading platform 2 of wrecker.Continue platform inclination oil cylinder (6) is shunk, loading platform (2) is the level of state, regain platform telescopic oil cylinder (9), make loading platform (2) playback, fix and dragged vehicle, it is solid to regain flexible square chest (10) of wedge shape and pin, can implement the back bracket movement.
