Embodiment 1

[0028] Such as Figure 2-3 As shown, the front beam 1, the middle beam 4 and the rear beam 5 are welded into one body with the left and right longitudinal beams of the semi-trailer respectively. The flap frame 2 is assembled and welded by two types of steel with different specifications, and the protective plate 3 is welded on the upper surface, and the flap bushing 7 is respectively welded on the front beam 1 and the flap frame 2, and then the flap frame 2. The flap shaft 6 is assembled with the front beam 1, and the two ends of the flap shaft 6 are respectively locked with cotter pins, so that the flap frame 2 can rotate around the flap shaft 6 on the front beam. According to the position of the shaft, The flap frame can be turned over 95° to 120°; fixed poles are installed on the flap frame 2 and the bottom frame to prevent the flap frame from falling down and hurting people. The flap frame 2 is a front and rear symmetrical device, and the nut 10 is tightened by the pressi...

Embodiment 2

[0031] Two beams are welded on the left and right longitudinal beams of the semi-trailer, that is, only one flap frame is arranged, and other structures are the same as in embodiment 1.

[0032] The present invention is also applicable to the use of car bodies of other models.

Abstract

The invention relates to a bottom plate overturning device of low plate semi-trailers, which is particularly suited to the semi-trailer of loading vehicles. The structure is designed as follows, a transverse beam is positioned between vertical beams at the two sides of the trailer body, a plate-overturn bracket is positioned between the transverse beams, and the plate-overturn bracket is movably connected with the transverse beam. The invention brings great benefits to inspection and maintenance, the maintenance operation can be directly carried out, all rear axles and accessories can be easily seen and faults can be easily found. Due to the elimination of jack lifting and trench operating facilities, the operation of the maintenance tools and the inspection tools can be easily carried outand the device can provide space for two or three persons to simultaneously operate. The invention ensures the safety of operators and meanwhile promotes maintenance efficiency and saves operation time.
