Problems solved by technology

However, in practical applications, it is found that the hydraulic system of the tank truck has great potential safety hazards: for example, for heavy tank trucks, due to the heavy weight of powder in the silo, which is about 40 tons, the outriggers must be unfolded before unloading the tank , otherwise there will be a rollover accident during the lifting process
However, the current back tanker does not have an outrigger first protection system, which is likely to cause a rollover accident

Abstract

The invention provides an advanced protecting system for support legs of a demountable tanker carrier. The advanced protecting system comprises main cylinders, support leg cylinders, a first electronic-control selector valve, a third electronic-control selector valve, a pressure oil source and a first pressure sensor, the first pressure sensor is used for detecting the pressure of rodless cavities of the support leg cylinders, when the pressure of the rodless cavities of the support cylinders is larger than or equal to a set value, a control signal is transmitted to the first electronic-control selector valve, and the first electronic-control selector valve controls the main cylinders to act when receiving the control signal from the first pressure sensor. By the aid of the advanced protecting system, the support legs are ensured to be completely opened when a lifting system works, and overturning risks are avoided. The invention further provides an advanced protecting method for the support legs of the demountable tanker carrier.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a system for protecting the outriggers of a tank truck and a method for protecting the legs of a tank truck in advance. Background technique [0002] At present, the operation of backing tank trucks is generally manual operation. The entire hydraulic system is relatively simple, mainly including three parts: lifting hydraulic system, mobile hydraulic system and outrigger hydraulic system. In addition to completing the normal basic actions of carrying and unloading tanks, little consideration is given to other safety measures. However, in practical applications, it is found that the hydraulic system of the tank truck has great potential safety hazards: for example, for heavy tank trucks, due to the heavy weight of powder in the silo, which is about 40 tons, the outriggers must be unfolded before unloading the tank , otherwise there will be a rollover accident during the lifti...
