Rear-dump wagon rollover prevention safe device

Abstract

The invention relates to a tail dumper side-turning preventing safety device consisting of a connection fixing device, connecting trunnions, a main hydraulic ram, an upper support arm, vertical supporting tools, a grounded wheel, a spindle head, a lower support arm and an auxiliary hydraulic ram. On the whole, the safety device is arranged at the basically central position of the load by adopting the structure form that the safety device is transversally and fixedly connected with two longitudinal beams of a load-carrying vehicle. Inner-end vertical supporting tools are arranged at the two ends of the connection fixing device fixed on the longitudinal beam of a vehicle frame. The upper connecting trunnion is arranged at the central position of the outer side surface of the upper end of the inner-end vertical supporting tool, and the main hydraulic ram is connected and arranged on the upper connecting trunnion in the form of shaft-pin connection. The external end of the main hydraulic ram is connected on the lower connecting trunnion in the form of the shaft-pin connection, while the lower connecting trunnion is arranged at the central position under the inner end surface of the outer-end vertical supporting tool. The spindle head is arranged on a position of the outer-end vertical supporting tool close to the lower part, and is provided with the grounded wheel which can freely rotate. The safety device has simple integral structure, reasonable mechanical structure, convenient installation, operation and use, and safety and reliability.

Description

Technical field: [0001] The invention relates to a safety auxiliary device for a truck, in particular to an anti-rollover safety device for a rear dump truck. Background technique: [0002] When the self-unloading truck is unloading at the unloading site, it is necessary to stop the vehicle steadily, and use the jacking hydraulic cylinder to raise the front end of the loading compartment, which is tilted backward, and the cargo will automatically slide out from the rear end of the compartment. Since the unloading site of this kind of truck is often uneven, it is easy to cause the body to tilt or sink during the unloading process, which may cause the car to overturn due to the shift of the center of gravity of the car. Chinese patent 200620088128.9 discloses a "dump truck anti-rollover device". It should be said that it is effective to a certain extent, but the overall structure is complicated, and the procedures for installation and operation are complicated, especially in t...
