Problems solved by technology

However, when vehicles such as rail lifting and high-altitude operations are lifting heavy objects or the operating platform is biased to one side, the deflection of the primary spring of the vehicle will change with the change of the load, resulting in shaking of the lifted heavy objects or the extended operating platform. Caused a great safety hazard, but also reduced the accuracy of the work
The hydraulic shock absorber cannot be locked to avoid shaking, and the vehicle must add additional support cylinders to solve the above problems

Embodiment 1

[0036] see figure 1 As shown, the embodiment of the present invention provides a hydraulic shock absorber with support function, including a cylinder 1, a piston assembly 2 is arranged inside the cylinder 1, and the piston assembly 2 divides the interior of the cylinder 1 into a rod cavity 11 and a Rodless chamber 12; cylinder 1 is provided with an oil storage tube 3; cylinder 1 upper end is provided with a cylinder end 4, and cylinder end 4 has an oil return hole 31 communicating with the oil storage tube 3; cylinder 1 lower end is provided with an inlet Oil valve assembly 7, the lower end of oil storage cylinder 3 is provided with passage 32 connected with oil inlet valve assembly 7; due. When the stop valve is opened, the shock absorber acts as a shock absorber; when the stop valve is closed, the two ends of the piston are equivalent to forming a closed cavity, and the piston rod cannot move, forming a support function. At this time, the shock absorber acts as a support de...

Embodiment 2

[0042] see Figure 6 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that in this embodiment, the coupling assembly 8 is in the form of a pin connection, including a pin seat 810 and a pin 811 .

Embodiment 3

[0044] see Figure 7 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that in this embodiment, the coupling assembly 8 is in the form of bolted connection, including a bolt seat 820 and a bolt 821 .

Abstract

The invention discloses a hydraulic shock absorber with a supporting function, and relates to the technical field of hydraulic shock absorbers. The hydraulic shock absorber comprises a cylinder barrel, a piston assembly is arranged in the cylinder barrel, and the interior of the cylinder barrel is divided into a rod cavity and a rodless cavity by the piston assembly; an oil storage barrel is arranged outside the cylinder barrel; the upper end of the cylinder barrel is provided with a cylinder end, and the cylinder end is provided with an oil return hole communicating with the oil storage barrel; an oil inlet valve assembly is arranged at the lower end of the cylinder barrel; a channel connected with the oil inlet valve assembly is arranged at the lower end of the oil storage barrel; and astop valve is arranged below the oil inlet valve assembly and used for controlling connection and disconnection of the channel.

Description

technical field [0001] The invention relates to the technical field of hydraulic shock absorbers, in particular to a hydraulic shock absorber with a supporting function. Background technique [0002] When the oil shock absorber in the prior art is working, the piston reciprocates in the inner oil cylinder, forcing the hydraulic oil to flow through the damping hole to generate damping force, and at the same time, the oil shock absorber converts the mechanical energy in the system into the energy of the hydraulic oil. The heat energy is dissipated into the air, so that the vibration of the rolling stock can be damped. However, when vehicles such as rail lifting and high-altitude operations are lifting heavy objects or the operating platform is biased to one side, the deflection of the primary spring of the vehicle will change with the change of the load, resulting in shaking of the lifted heavy objects or the extended operating platform. Cause great potential safety hazard, a...
