Abstract

The invention discloses a turnover-type self-discharging semitrailer with the low gravity centre supported by a rear hub. A turnover centre of a self-discharging container (2) is a turnover central pin shaft (10) that a semitrailer chassis (8) is connected with a container bottom frame (15), and a rear hub (12) is used as a turnover support point. A lower-opening back box plate (18) is arranged on the back end surface of the self-discharging container (2) and matched with a hook inhaul cable mechanism (16); a hydraulic lifting cylinder (6) is arranged on an oil cylinder support (7) of the semitrailer chassis (8), and the top end of the cylinder is connected to a raising support (4) of the container bottom frame (15). A hydraulic pump (39) pumps the hydraulic oil into a lifting valve (35),and the hydraulic oil enters a hydraulic lifting cylinder (6) when the hydraulic pump (39) is operated, the cylinder raises up the front part of the self-discharging container (2), the container bottom frame (15) uses the rear hub (12) as a support point, the self-discharging container (2) turns backwards around the turnover central pin shaft (10), an inhaul cable (S) is loosened to enable the hook (G) to be automatically loosened, and the lower end of the back box plate (18) is opened to dump the goods. The invention has the advantages of low gravity centre for discharging and favorable stability, increases the security and realizes automation of opening the box and discharging.

Description

technical field [0001] The invention relates to a freight semi-trailer, in particular to a dump semi-trailer. Background technique [0002] At present, the domestic transportation of bulk materials mostly uses rear-turning self-unloading semi-trailers. The hydraulic lifting mechanism lifts the front of the self-unloading container and dumps the goods backward. The turning support points are all on the top of the semi-trailer chassis. , resulting in poor unloading stability. In order to improve the unloading stability, various measures and their combinations are adopted in the structural form, such as the outer-span container bottom frame, the widened flip seat, the reinforced anti-swing frame, etc. Although the stability has been improved, there is still insufficient stability when lifting the self-unloading container to unload under the condition of full load. The requirements for the road surface of the parking unloading site are relatively high, and unloading on uneven r...
