Abstract
The invention discloses a three-stage platform carrying structure of a wrecker. The three-stage platform carrying structure comprises a first stage large platform, a second stage small platform and a third stage small platform. The tail end of the first stage large platform is hinged to the connecting end of the second stage small platform and the connecting end of the third stage small platform. A groove type slideway of the first stage large platform, a groove type slideway of the second stage small platform, a groove type slideway of the third stage small platform and a rectangular longitudinal beam guide rail of an auxiliary wrecker frame are slidably connected with one another in a matched and embedded mode. A platform derricking oil cylinder is arranged between the auxiliary wrecker frame and a chassis longitudinal beam below. The tail portion of the chassis longitudinal beam is hinged to the bottom side of the auxiliary wrecker frame. A supporting leg is arranged at the bottom of the tail end of the auxiliary wrecker frame. The bottom of the first stage large platform and the front end of the auxiliary wrecker frame are each provided with a platform telescopic oil cylinder hinge point connected with a platform telescopic oil cylinder. Through telescoping motion of the platform telescopic oil cylinder, the first stage large platform, the second stage small platform and the third stage small platform are made to slide longitudinally, stretch backwards and slide to working positions in sequence in an inclined state. The inclination angles between the three platforms and the ground after the three platforms slide backwards and downwards to the working positions are A, B and C correspondingly, and A>B>C.
Description
Technical field
The present invention relates to the Three-level Platform piggy-back structure of a kind of obstacles removing car, be specifically related to a kind of for public security, traffic administration, save, the platform piggy-back mechanism of the road obstacle clearing vehicle of department's cleaning accident such as maintenance, fault, vehicles peccancy.
Background technology
Platform piggy-back mechanism is one of current road obstacle clearing vehicle primary structure, its function be relieved vehicle is dragged lead be positioned on flat board after delivery walk.In the wrecker of the most existing production and use, whole piggy-back platform is divided into monoblock type and collapsible two kinds of segmentation.These design structures have following weak point: when monoblock type flat board uses, after moving one end ground connection after flat board, minimal tilt angle is determined with the length of platform by the terrain clearance of the hinge point on chassis member, and its minimum ground connection inclination angle is at about 13 °；The segmentation convertible tablet improved on integral type foundation, although improving angle during flat board ground connection, but minimal tilt angle is still at about 7 °, being difficult to change design structure makes it reduce further, when the most relieved vehicle front overhang is the lowest, approach angle is the least, during dragging and leading upper mounting plate, its front lower portion is easy to simulation platform face and damages vehicle, therefore the design of this mechanism can not adapt to, and chassis front overhang is extremely low, the piggy-back of the least vehicle of approach angle.
It is desirable to provide in the case of a kind of vehicle frame terrain clearance on chassis and land lengths are fixed, can significantly subtract the treadmill body of two or three grades of chain-wales and the obstacles removing car at minimal tilt angle, ground, lead adapting to the safe support of various types of vehicles.
