Technical Field

The invention relates to a vibration reduction mechanism of a fork lift truck.

Background

The existing stacking machine utilizes a mode that a front bridge and a rear bridge support a front cross beam and a rear cross beam. The front cross member 100 supported by the front axle 101 has both ends in the shape of wings, and the rear cross member 200 supported by the rear axle 201 has the shape of a spindle.

The damping principle of the conventional stacking machine is that a beam is supported by a damping oil cylinder 1, the beam comprises a front beam 100 and a rear beam 200, and the front beam and the rear beam are supported at two ends of the front beam and the rear beam by a pair of damping oil cylinders 1 respectively; both ends of the front cross member 100 are supported by two shock-absorbing cylinders 1 at both ends on the front axle 101, and the rear cross member 200 is also supported by one shock-absorbing cylinder 1 at both ends on the rear axle 201, and the up-and-down vibration of the front and rear cross members is absorbed by compressing the four shock-absorbing cylinders 1, as shown in fig. 1 and 2.

Such a damping mechanism can not meet the needs of users if the damping cylinder 1 itself fails to have a poor damping effect.

Disclosure of Invention

Aiming at the defects that the shock absorption effect is poor and the requirements of users cannot be met if the shock absorption oil cylinder per se of the existing shock absorption mechanism fails, the invention provides the shock absorption mechanism of the fork lift truck.

The technical scheme adopted by the invention for realizing the technical purpose is as follows: a shock absorption mechanism of a fork lift truck is respectively arranged between a front cross beam and a front axle as well as between a rear cross beam and a rear axle and comprises a pair of shock absorption oil cylinders arranged between two wings of the front cross beam and the front axle and a pair of shock absorption oil cylinders arranged between two ends of the rear cross beam and the rear axle; and second damping devices are arranged between the two feet of the front cross beam and the front axle and between the two feet of the rear cross beam and the rear axle.

In the invention, because the second damping devices are arranged between the two feet of the front cross beam and the front axle and between the two feet of the rear cross beam and the rear axle, when the damping oil cylinder fails, the second damping devices can be used for damping, thereby meeting the requirements of users.

Further, in the above-described shock absorbing mechanism of a forklift: the second damping device is a disc-shaped damper.

Further, in the above-described shock absorbing mechanism of a forklift: the damping oil cylinder is a hydraulic oil cylinder without a rod cavity and is provided with an energy storage leather bag communicated with the damping oil cylinder.

Further, in the above-described shock absorbing mechanism of a forklift: the capacity of the energy storage leather bag is 1-3 liters.

Further, in the above-described shock absorbing mechanism of a forklift: the inner diameter of the cylinder barrel of the damping oil cylinder arranged between the rear cross beam and the rear axle is larger than 140 mm.

The present invention will be further described with reference to the accompanying drawings and detailed description.
