Referring to fig. 1 to 4, an embodiment of the application provides a lightweight dump semi-trailer carriage with a safety structure, which comprises a carriage body 1 and a door 2 arranged on the carriage body 1, wherein a pressure cylinder 3 is arranged on the carriage body 1, the inner wall of the pressure cylinder 3 is connected with a piston plate 4 in a sliding and sealing manner, the pressure cylinder 3 is connected with a pressure frame 5 in a sliding and clamping manner, the pressure frame 5 is connected with the piston plate 4, a first spring 6 is arranged in the pressure cylinder 3, the first spring 6 is connected with the piston plate 4, a pressure pipe 7 is arranged on the carriage body 1, the pressure pipe 7 is distributed on two sides in the carriage body 1, the pressure pipe 7 is communicated with the pressure cylinder 3, a pressure telescopic rod 8 is arranged on the carriage body 1, the pressure pipe 7 is communicated with the pressure telescopic rod 8, a friction plate 9 is arranged on the pressure telescopic rod 8, a second spring 10 is arranged on the carriage body 1, the second spring 10 is connected with the friction plate 9, a telescopic support rod 11 is arranged on the carriage body 1, and the telescopic support rod 11 is connected with the friction plate 9.
In this embodiment, the pressure source in the pressure cylinder 3 may be air pressure or hydraulic pressure, so that the air pressure may be selected for the lightweight pressure source of the dump semitrailer, when the dump semitrailer is used for sudden braking during transportation of the goods, the goods slide forward due to inertia, so as to squeeze the pressure frame 5 sliding on the pressure cylinder 3, the pressure frame 5 drives the piston plate 4 to slide into the pressure cylinder 3, the air pressure in the pressure cylinder 3 and the spring 6 cause a certain squeezing buffer effect on the piston plate 4, meanwhile, when the piston plate 4 is used for squeezing the air in the pressure cylinder 3, the air pressure moves the friction plate 9 forward along the pressure pipe 7 through the pressure telescopic rod 8, and the friction plates 9 mounted on both sides simultaneously exert force to squeeze and rub the goods, so that the goods are prevented from being deflected by only one side force, the braking efficiency is also improved, the radial force born by the pressure telescopic rod 8 is reduced, and the friction plate 9 on the pressure telescopic rod 8 is prevented from being deflected, so that the friction force is reduced. When the goods stop sliding forward, the second spring 10 drives the pressure telescopic rod 8 to shrink through the friction plate 9, so that the gas pressure in the pressure pipe 7 is squeezed back into the pressure cylinder 3 again, and the safety structure is reset automatically.
In some embodiments, in order to increase the weight reduction of the dump semitrailer, the carriage body 1 is provided with a weight reduction groove 12, and the pressure pipe 7 is matched with the weight reduction groove 12.
