Hydraulic support leg

Abstract

The hydraulic support legs are set in the right and left sides of electric stacking vehicle. Each of the hydraulic support legs includes one hydraulic cylinder and its piston rod, one rotating pinshaft in the lower end of the piston rod, one movable support leg connected to the pinshaft, one servo wheel connected outside the upper end of the support leg, one leg supporting pinshaft in the lower end of the support leg and connected to the lower part of the vehicle body, and one vehicle pinshaft set in the upper end of the hydraulic cylinder connected to the middle part of the vehicle body. When the stacking vehicle lifts cargo, hydraulic oil enters to the cavities of the hydraulic cylinders, the pistons stretch downwards to make the support legs rotate downwards to the ground and the servo wheels contact the ground to support the stacking vehicle stably. The present invention can raise the performance of the stacking vehicle.

Description

technical field [0001] The invention relates to the field of hydraulic devices, in particular to a hydraulic support leg of a stacker truck. It is mainly used on high-lift stacker trucks to realize good stability of the car body when the stacker trucks are lifted; the invention is also suitable for supporting use on various transport tools for carrying and lifting goods. Background technique [0002] At present, with the rapid development of modern industry and logistics industry, a large number of products need to be transported and stacked after they are produced. The electric stacker is an efficient handling tool for indoor stacking, with the characteristics of small size and small turning radius. And the described electric handling stacker truck that is currently used in the warehouse requires the height of the goods to be lifted higher and higher, but the width between the car body of the stacker truck and its left and right wheel legs cannot be increased year-on-year....

AI Technical Summary

Problems solved by technology

And the described electric handling stacker truck that is currently used in the warehouse requires the height of the goods to be lifted higher and higher, but the width between the car body of the stacker truck and its left and right wheel legs cannot be increased year-on-year. Large; when the ratio between the lifting height and the width between the left and right wheel legs is greater than 5, the electric pallet truck will lose its stability when the load is raised or the goods are picked up from high altitude, and it is easy to tip over

[0003] At present, there are all kinds of electric pallet trucks on the market, but most of them have the problem of coordination between the width between the left and right wheel legs of the electric pallet truck and the ratio of load lifting and high-altitude picking. , which restricts the working capacity of the electric pallet truck itself

In order to prevent the goods from tipping over or even falling during the process of lifting the load and picking up goods from high altitude and causing damage to the goods, the width between the left and right wheel legs of the existing electric stacker truck must be restricted. , which restricts the working efficiency of electric pallet trucks currently on the market
