Background technique

A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device and other components. In civil engineering, dump trucks are often combined with construction machinery such as excavators, loaders, and belt conveyors to form a loading, transporting, and unloading production line for loading and unloading of earthwork, sand, and bulk materials.

Most of the dump trucks in the prior art lift the cargo from one side, and usually only stabilizer legs are installed on the side of the lifting device, which will not affect the stability of the cargo lifting process for the crane, because the two sides of the crane Stabilizers are usually installed.

However, there are still some potential safety hazards for trailer-mounted side-loaded containers, because one side of the container is stressed, and it is easy to shift and swing during the process of being lifted, especially when the container is moved and lifted above the trailer. When operated by unskilled operators, the container will sway from side to side. When the container moves to the side without a stabilizer, it will cause the container and even the entire trailer to overturn, which poses a huge safety hazard.

Mounting on tipper trucks.

Advantage and beneficial effect of the present utility model are:

1. This device includes a telescopic support part and a folding arm. The telescopic support part is connected to the folding arm shaft. A telescopic device is arranged on the telescopic support part. The telescopic device is driven by a hydraulic cylinder to realize the expansion and contraction of the telescopic part, and the folding arm is folded on the self Easy to use when unloading.

2. The hydraulic cylinder of this device uses a pilot-operated check valve and an air pipe to drive the piston rod of the cylinder to push the telescopic device. The telescopic device includes a plunger, a pulley, a sector and a flexible element. The hydraulic cylinder drives the piston rod upward, and the bottom of the piston rod The support seat of the support seat touches the plug of the telescopic device, and the plug moves upward through the sleeve, thereby driving the flexible element fixed at one end to the cap to stretch upward through the pulley, driving the stretching of the other end of the flexible element, and then driving the hydraulic cylinder along the The crankshaft of the folding arm rotates, and the folding of the telescopic supporting parts is completed through forward and reverse actions.

3. The utility model provides an auxiliary balance device suitable for dump trucks. The design is scientific and reasonable, and the structure is simple. A telescopic device is installed on the telescopic support part, driven by a cylinder, and the reciprocating action realizes the retraction of the telescopic support part. It is suitable for automatic The auxiliary balance support of the unloading truck improves the stability of the dump truck loading and unloading the container, effectively improves the safety, and conforms to the national standard, and is suitable for mass promotion and use.
