Auxiliary lifting stabilizing mechanism for self-dumping semitrailer and using method thereof

Abstract

The invention relates to the technical field of self-dumping semitrailers, in particular to an auxiliary lifting stabilizing mechanism for a self-dumping semitrailer and a using method of the auxiliary lifting stabilizing mechanism; the auxiliary lifting stabilizing mechanism comprises a frame, an auxiliary stabilizing device, a detecting device and an auxiliary discharging device, the auxiliary stabilizing device is arranged on the inner side of the frame, and the top end of the frame is rotationally connected with a carriage through a rotating shaft; and the detection device is arranged on the right side of the top end of the vehicle frame and comprises a second multi-stage hydraulic rod, the right end of the outer side of the carriage is rotationally connected with the second multi-stage hydraulic rod through the rotating shaft, and the other end of the second multi-stage hydraulic rod is rotationally connected with a fixing block through a rotating shaft. According to the invention, a pressure sensor and the fixing block are arranged; the arrangement is matched with the elasticity of a first spring to an extrusion block and the fixing block, the fixed connection of the extrusion block and the pressure sensor and the fixed connection of the fixing block and the alarm, when the mechanism is used, the load condition of the device can be automatically detected, so that accidents caused by overweight are avoided.

Description

technical field [0001] The invention relates to the technical field of dump semi-trailers, in particular to an auxiliary lifting and stabilizing mechanism for dump semi-trailers and a method for using the same. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semi-trailer is generally a three-axle semi-trailer, and its types are divided into eleven-meter barn semi-trailers. There are many kinds of thirteen-meter barns, low-bed semi-trailers, etc., which are a kind of heavy-duty transportation vehicles connected to the head of the semi-trailer through the traction pin. With the continuous development of society, there are more and more applications for semi-trailers. However, when some semi-trailers are lifted during use, the stability during lifting is poor, especially when the load is large, it is...

[0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semi-trailer is generally a three-axle semi-trailer, and its types are divided into eleven-meter barn semi-trailers. There are many kinds of thirteen-meter barns, low-bed semi-trailers, etc., which are a kind of heavy-duty transportation vehicles connected to the head of the semi-trailer through the traction pin. With the continuous development of society, there are more and more applications for semi-trailers. However, when some semi-trailers are lifted during use, the stability during lifting is poor, especially when the load is large, it is easy to be unevenly stressed and roll over, which has a large safety hazard. There are some auxiliary and stable structures, but it is inconvenient to install, and it is not convenient to detect the load, and it is easy to cause accidents when lifting and unloading under overload conditions. Unloading the cargo, using inertia to unload the vehicle through a violent forward method will cause serious damage to the vehicle body, which will shorten the service life of the semi-trailer
