Problems solved by technology

The shock absorbing spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. In order to absorb the excess vibration caused by the reciprocating movement of the spring, the existing technology uses a hydraulic rod to absorb it, and the life of the hydraulic rod and the spring different, resulting in the service life of the entire shock absorber being equal to the service life of the prematurely damaged item
Therefore, after the existing spring shock absorber is damaged, the entire shock absorber needs to be removed, replaced or repaired (mainly replaced with a new one), which brings about the disassembly of the equipment. If it is carried out in an assembly environment, it will cause invisible damage to the equipment, and it will take a long time to disassemble and install; because one of the hydraulic rods or springs is damaged, replacing the original damaged object with a new one cannot achieve a new one. The service life of the shock absorber is very small, so there is very little maintenance, and when it is directly replaced, one of the items is still good, which brings a huge waste of resources

Embodiment 1

[0015] A flexible spring shock absorber, comprising a shock absorber shaft 1, a connecting sleeve 2 installed at both ends of the shock absorber shaft 1, and a dynamic pressure plate 3 sleeved on the oil cylinder body of the shock absorber shaft 1. A tension spring 4 and a pressure spring 5 are arranged between the pressing plate 3 and the two connecting bushes 2, and the tension spring 4 is in a stretched state in a non-working state.

[0016] The joint use of the tension spring and the pressure spring makes the pressure spring work when the entire shock absorber is stressed, and the tension spring works when the shock absorber returns. The tension spring cooperates with the pressure spring to achieve shock absorption and reduce the reciprocating motion of the spring frequency, so as to achieve the ideal shock absorption effect and prolong the service life of the shock absorber shaft.

Embodiment 2

[0019] As a structural design for Example 1, a pressure spring installation plate 6 is provided at the installation place of the piston rod of the shock absorber 1 and the connecting sleeve 2, and a limit position is provided on the cylinder body of the shock absorber 1 close to the piston rod. Plate 7, and a tension spring mounting plate 8 is arranged on the other side close to the connection bushing 2, and a pressure spring 5 is installed between the pressure spring mounting plate 6 and the dynamic pressure plate 3, and a tension spring mounting plate 8 is installed between the dynamic pressure plate 3 and the tension spring mounting plate 8. Tension spring 4.

[0020] This embodiment is a structure in which tension springs and pressure springs are connected. The design of the limit plate 7 is to keep the tension spring stretched in the non-working state, while the pressure spring is not compressed in the non-working state. Only in this way can it be ensured that in the work...

Embodiment 3

[0022] As a structural design for Example 1, a tension spring mounting plate 8 is provided at the installation place of the piston rod of the shock absorber 1 and the connecting sleeve 2, and a limit position is provided on the cylinder body of the shock absorber 1 close to the piston rod. Plate 7, and a pressure spring mounting plate 6 is arranged on the other side close to the connecting shaft sleeve 2, a pressure spring 5 is installed between the pressure spring mounting plate 6 and the dynamic pressure plate 3, and a pressure spring 5 is installed between the dynamic pressure plate 3 and the tension spring mounting plate 8 Tension spring 4.

[0023] This embodiment is another structure in which tension springs and compression springs are connected, and the principle is the same as that of Embodiment 2.

Abstract

The invention discloses a flexible spring shock absorber. The flexible spring shock absorber comprises a shock absorption shaft and connecting shaft sleeves mounted at the two ends of the shock absorption shaft. A moving press plate connected to an oil cylinder body of the shock absorption shaft in a sleeving manner is arranged on the oil cylinder body of the shock absorption shaft. Tension springs and a pressure spring are arranged between the moving press plate and the two connecting shaft sleeves. In a non-work state, the tension springs are in a stretching state. By means of the flexible spring shock absorber, through combined use of the pressure spring and the tension springs, repeated vibration is eliminated in the pressing and resetting process, the shock absorption effect is good,the shock absorption shaft is protected, and the service life is prolonged; and through use of the multiple springs, the stiffness factor of each single spring is low, the shock absorption effect is good, and when a single spring is damaged, only the spring needs to be taken down from a hook to be replaced, and the whole shock absorber does not need to be demounted.

Description

technical field [0001] The invention relates to a spring shock absorber, in particular to a flexible spring shock absorber. Background technique [0002] The spring shock absorber absorbs shock through the spring and is often used to control the continuous fluid vibration disturbance. The shock absorption of the spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. In order to absorb the excess vibration caused by the reciprocating movement of the spring, the existing technology uses a hydraulic rod to absorb it, and the life of the hydraulic rod and the spring Different, causing the service life of the entire shock absorber to be equal to the service life of the damaged object in advance. Therefore, after the existing spring shock absorber is damaged, the entire shock absorber needs to be removed, replaced or repaired (mainly replaced with a new one), which brings about the disassembly of the equipment. If ...
