Problems solved by technology

These design structures have the following deficiencies: when the integral flat panel is used, when the flat panel moves backward and one end is grounded, the minimum inclination angle is determined by the height of the hinge point on the chassis longitudinal beam from the ground and the length of the platform, and the minimum ground inclination angle At about 13°; the segmented folding flat panel improved on the basis of the whole, although the angle when the flat panel is grounded has been improved, the minimum

Example Embodiment

[0020] Example 1

[0021] Such as figure 2 As shown, a three-level platform back-loading structure of a wrecker truck is provided with a sub-frame 1, a first-level large platform 2 and a second and third-level small platform 4, and the second and third-level small platforms are hingedly connected by the first hinge point 3. The first-level large platform trough slideway 12 and the second and third-level small platform trough slideway 15 are slidably embedded with the subframe rectangular longitudinal beam guide rails, and a platform is provided between the subframe 1 and the chassis longitudinal beam 9 below Luffing cylinder 8, sub-frame 1 is hinged to the rear of the chassis longitudinal beam through hinge point 7, the end of the sub-frame is provided with outriggers 6, the bottom of the large platform 2 and the front end of the sub-frame 1 are respectively provided with platform telescopic cylinder hinge points 5 , 10. Among them: the first-level large platform 2 is welded ...

Example Embodiment

[0022] Example 2 ： In this embodiment, the platform stamping and bending plates in the first-level large platform 2 and the second and third-level small platforms 4 in embodiment 1 are replaced by platform stamping and bending plates. Figure 4 As shown, its strength and supporting effect are better, and rectangular supporting beams can be omitted.

[0023] Such as image 3 As shown, a three-level platform back-loading structure of a wrecker truck is provided with a sub-frame 1, a first-level large platform 2 and a second and third-level small platform 4, and the second and third-level small platforms are hingedly connected by the first hinge point 3. The first-level large platform trough slideway 12 and the second and third-level small platform trough slideway 15 are slidably interlocked with the sub-frame rectangular longitudinal beam guide rails, and a platform change is provided between the sub-frame and the lower chassis longitudinal beam 9 The width cylinder 8 and the sub-...

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 [0001] The invention relates to a three-stage platform back-loading structure of a wrecker, in particular to a platform back-loading mechanism of a road wrecker used in public security, traffic management, rescue, maintenance and other departments to clean up accidents, faults, and illegal vehicles. Background technique [0002] The platform carrying mechanism is one of the main structures of the current road wrecker. Its function is to tow and place the rescued vehicle on the flat plate and carry it away. Among the flatbed wreckers currently produced and used in China, the entire back-carrying platform is divided into two types: integral type and segmented folding type. These design structures have the following deficiencies: when the integral flat panel is used, when one end of the flat panel is moved backward and grounded, the minimum inclination angle is determined by the height of the hinge point on the chassis longitudinal beam from the ground and the l...
