Lift slideway

Abstract

The invention discloses a lifting slideway as a brand-new component, which is mainly composed of a hydraulic oil cylinder, a lifting crank arm, a lifting connecting rod, a slideway shell, a connecting rod crank arm, a lifting fork, a lifting roller and various rotating shafts, and is characterized in that : The fixed shaft seat of the hydraulic cylinder, the fixed shaft seat of the crank arm and the slideway shell are fixed on the chassis of the truck. The fixed shaft seat of the hydraulic cylinder and the fixed shaft seat of the crank arm are located at the bottom of the front end of the truck, and the height is lower than that of the truck beam. The slideway shell Located on a load-bearing mass. The fixed shaft of the hydraulic cylinder is fixed on its shaft seat, and the oil cylinder that controls the lifting slideway can rotate around its fixed shaft during work; The arms are fixed together, sleeved on the crank arm fixed shaft, and can rotate around it. The invention greatly reduces the movement resistance of the cargo box on the truck chassis, enables the cargo box to advance and retreat on the truck chassis more conveniently, thereby helping the smart car to realize the advantages of automatic loading and unloading functions more quickly.

Description

technical field [0001] The invention relates to a chassis auxiliary structure of a novel "box dumping" truck. Background technique [0002] As an auxiliary component of the chassis of Geili container intelligent loading and unloading truck, the lifting slideway is mainly used to reduce the movement resistance of the container on the truck chassis, and assist the container to move forward and backward more freely on the truck chassis, thus assisting the smart car to realize the cargo more quickly. Automatic loading and unloading of boxes. [0003] The biggest advantage of Geili container intelligent loading and unloading truck is that it can realize automatic loading and unloading of containers, so the smooth, convenient and labor-saving process of "automatic loading and unloading" has become a key consideration. On the one hand, the load of the logistics car is relatively large, especially when it is fully loaded, the load may reach more than ten tons or even dozens of tons...

AI Technical Summary

Problems solved by technology

On the one hand, the load of the logistics car is relatively large, especially when it is fully loaded, the load may reach more than ten tons or even dozens of tons. On the other hand, all the load of this special container will eventually fall on the bottom of the container. Two square beams, and the square beams fall on the two girders on both sides of the truck chassis. If there is no auxiliary structure, when the box advances and retreats on the truck chassis, the resistance = cargo box load x square beams and chassis beams The sliding friction coefficient between steel and steel is generally 0.15 when there is no lubrication, and 0.05 to 0.12 when there is lubrication. If lubricant is used, it will easily cause the shaking of the box on the chassis, which is not good for safety. , and the structure itself is inconvenient to add lubricant. It can be seen that when the box moves forward and backward on the truck chassis, the friction coefficient is 0.15, and the resistance will be very large
