Safety auxiliary device for unloading of dump truck

Abstract

The invention relates to the technical field of constructional engineering, and discloses a safety auxiliary device for unloading of a dump truck, which comprises a rotating shaft. A rotating disc is fixedly connected to the outside of the rotating shaft, a first shell is fixedly connected to the inside of the rotating disc, a stop lever is movably connected to the inside of the first shell, and a shell is movably connected to the outside of the rotating shaft. The interior of the shell is fixedly connected with a fixing ring, the interior of the fixing ring is fixedly connected with a coil, the interior of the shell is fixedly connected with a second shell, and the interior of the second shell is provided with an electrorheological body. Through the interaction of the rotating shaft, the rotating disc, the first shell, the stop lever, the support, the photosensitive assembly and the alarm, when the vehicle unloads, if the vehicle suddenly moves forwards, an alarm can be given to remind surrounding personnel to pay attention to safety, meanwhile, a driver is reminded to control the vehicle, and when the vehicle runs normally, the device structure does not affect normal rotation of the rotating shaft, and therefore, the driving of the vehicle is not influenced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a safety auxiliary device for dump truck unloading. Background technique [0002] Dump truck refers to a special vehicle that uses the engine power of the vehicle to drive the hydraulic lifting mechanism, tilts its compartment at a certain angle to unload, and relies on the self-weight of the compartment to reset it. It is mainly responsible for the transportation of construction materials such as fine sand and gravel. [0003] Dump trucks rely on the gravity of the cargo to unload. When unloading, the driver stays in the cab to control, so that the driver cannot accurately judge the position of the compartment, and when the compartment is lifted for unloading, due to the weight of the cargo. The influence of gravity will greatly reduce the stability of the vehicle. The driver must observe the movement state of the compartment while operating, and the attention w...
