Truss folding type hydraulic flip plate

Abstract

The invention discloses a truss folding type hydraulic flip plate with good synchronization, convenient operation and safety and reliability on cylinders on the two sides. The truss folding type hydraulic flip plate comprises a hydraulic flip plate supporting platform, wherein one end of the hydraulic flip plate supporting platform is hinged with a base. A lifting mechanism is arranged below the hydraulic flip plate supporting platform, the lifting mechanism comprises the lifting cylinders arranged on both sides of the hydraulic flip plate supporting platform, one ends of the lifting cylindersare movably connected with the hydraulic flip plate supporting platform, and the other ends of the lifting cylinders are movably connected with the base. A truss folding type self-synchronization system is further arranged below the hydraulic flip plate supporting platform, and the truss folding type self-synchronization system is arranged on the lower part of the hydraulic flip plate supportingplatform and between the base joint end and the lifting mechanism. The truss folding type hydraulic flip plate is suitable for unloading bulking materials in an automobile by using a hydraulic flip plate.

Description

technical field [0001] The invention relates to the technical field of automatic car unloading, in particular to a truss folding hydraulic flap used in a car unloading machine. Background technique [0002] In the unloading of bulk materials in automobiles, an unloading machine is usually used, and a hydraulic flap is usually used in the unloading machine. Generally, an unloading platform is used to automatically load dozens of tons to hundreds of tons of bulk materials in a car under the action of a hydraulic system in a short period of time. All unloading within a certain period of time, the working process is to first drive the truck to the hydraulic unloading platform, start the car stop device, lift the platform with the hydraulic system, and when it reaches a certain angle, the bulk cargo will automatically slide down, which is efficient, easy to operate, It is safe and reliable, and has less dust pollution, which meets the requirements of environmental protection and ...

AI Technical Summary

Problems solved by technology

This structure has a big defect, because the two oil cylinders have to be extended to 8 to 10 meters or more, and at the same time, due to the uneven load on the support platform, the weight of the oil cylinders on both sides of the vehicle is different, resulting in two The oil cylinders cannot rise synchronously. When the synchronization error exceeds a certain amount, it will not only cause damage to the equipment, but also easily cause safety accidents due to vehicle rollover. In order to solve the synchronization problem of the two oil cylinders, only the oil cylinder synchronization device can be added. A two-cylinder synchronous device adopted includes main components such as a rope sensor and a flow proportional valve. When the numerical value is used, the opening of the proportional valve connected to the oil cylinder is controlled, so as to realize the linear adjustment function of the two oil cylinders, but the stability of this structure is poor and the manufacturing cost is high; another oil cylinder synchronization device includes a synchronous motor. The two oil cylinders supply the same amount of oil to realize the synchronous lifting of the two oil cylinders, but this method requires high rigidity of the flap support platform, plus the manufacturing accuracy of the synchronous motor itself is limited, and the load on the support platform is uneven and other factors , the longer it is used, the worse the synchronization
