Problems solved by technology

The return spring in this type of device plays a certain buffering role, but the travel of the spring in this type of device is limited, and its elastic coefficient is not large for easy contact and depression, so the role of the spring as a buffering element is limited

Embodiment Construction

[0021] Such as Figure 1 to Figure 3 As shown, a spring hydraulic buffer protection device provided by the present invention is a built-in spring type, including an end cover 1, a piston barrel 2, a thrust spring 3, a piston 4, a small sealing ring 5, a large sealing ring 6, and a sleeve 7 , return spring 9, gasket 10, gasket stopper 11, damping cylinder 12, support seat 15, sealing bolt 16. The right end of piston cylinder 2 is put into sleeve 7 and fits with sleeve 7, and damping cylinder 12 is formed by The inner hole of the piston barrel 2 is loaded into the sleeve 7, and is fixed in the sleeve pipe 7 by the support seat 15 with the sealing bolt 16, and sealant is required for fixing. The piston 4 on the damping cylinder 12 is limited on the piston cylinder 2 to form a chamber one 8 . The wall of the damping cylinder 12 isolates the space on the right side of the piston 4 and divides it into cavity two 14 and cavity three 13 . Between the piston 4 and the piston barrel 2...

Abstract

The invention relates to a spring hydraulic buffer protection device. Kinetic energy of a shuttle vehicle is converted into internal energy of liquid and elastic potential energy of springs through the flowing damping characteristic of the fluid and elastic deformation of the springs. Another technological scheme of the invention provides the shuttle vehicle. The shuttle vehicle comprises a vehicle body, and the front side and the rear side of the vehicle body are each provided with a transversely-arranged bumper bar. The shuttle vehicle is characterized in that the front side and the rear side of the vehicle body are each provided with a spring hydraulic buffer protection device pair, and each spring hydraulic buffer protection device pair at least comprises two spring hydraulic buffer protection devices. According to the spring hydraulic buffer protection device and the shuttle vehicle, the problem that mechanical damage, electrical failure, cargo toppling and the like occur possiblydue to the fact that the shuttle vehicle is collided and impacted can be solved, and the spring hydraulic buffer protection device has the advantages of having the functions of early warning, inertiaimpact buffering, automatic smoothing and recovering and the like.

Description

technical field [0001] The invention relates to a spring hydraulic buffer protection device and a shuttle car, belonging to the field of warehouse logistics automation. Background technique [0002] The shuttle car belongs to the lifting device, and its load mass in the working state reaches 1t to 2t, and the running speed is 1m / s to 2m / s, so the kinetic energy of the entire car body and cargo is very large. When the existing shuttle car encounters an obstacle in the direction of travel, emergency braking measures have been taken. However, due to the large kinetic energy of the shuttle car system, even if emergency braking is adopted, the shuttle car system will still have a rather long braking distance. When the distance between the shuttle car and the obstacle is less than the braking distance, the two will inevitably collide. Also, if the braking system fails, the crash is even more damaging. The energy impact during the collision will cause damage to the mechanical st...
