Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a rubber shock absorber for engineering machinery. Background Art

[0002] Spring shock absorbers are often used in engineering machinery construction. Spring shock absorbers are often used to control the vibration of piping systems caused by continuous fluid vibration disturbances (such as fluid pulsation, two-phase flow, high-speed flow and wind vibration).

[0003] The existing rubber spring shock absorber generally includes an upper flange, a lower flange and a rubber shock absorber arranged therebetween. When the rubber spring shock absorber is subjected to a vibration source, the upper flange and the lower flange squeeze the rubber shock absorber against each other. However, since the relative moving distance between the upper flange and the lower flange is not adjustable, the elastic force of the rubber spring shock absorber cannot be adjusted. Therefore, a rubber shock absorber for engineering machinery is proposed. Utility Model Content

[0004] The utility model aims to solve the problem that the elastic force of the rubber shock absorber in the prior art cannot be adjusted, and proposes a rubber shock absorber for engineering machinery.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rubber shock absorber for engineering machinery comprises an upper flange, a lower flange and a rubber shock absorber, wherein the rubber shock absorber is arranged between the upper flange and the lower flange, and an elastic adjustment mechanism is provided between the upper flange and the lower flange and on both sides of the rubber shock absorber; the elastic adjustment mechanism comprises a support sleeve, a support rod and a spring, the support sleeve and the support rod are respectively fixedly arranged on the upper flange and the lower flange, and the upper end of the support rod is inserted into the lower end of the support sleeve, an adjustment pressure block is slidably provided inside the support sleeve, the spring is fixedly arranged between the adjustment pressure block and the support rod, a screw is threaded on the top of the support sleeve, the lower end of the screw is rotatably connected to the top of the adjustment pressure block, and a knob is fixedly provided on the upper end of the screw.

[0007] Preferably, fixing rods are fixedly provided on both sides of the upper end of the support sleeve, and the upper ends of the two fixing rods are fixedly connected to the upper flange.

[0008] Preferably, the knob is located between two fixing rods.

[0009] Preferably, two limit blocks are symmetrically fixedly provided on the upper end of the support rod, and limit grooves matching with the limit blocks are provided on both sides of the support sleeve.

[0010] Preferably, the regulating pressing block is a square block, and the supporting sleeve is a square tube.

[0011] Preferably, the elastic adjustment mechanism adopts a PVC mechanism component.

[0012] Compared with the prior art, the utility model provides a rubber shock absorber for engineering machinery, which has the following beneficial effects:

[0013] The rubber shock absorber for engineering machinery is provided with a support sleeve, a support rod, a spring, an adjusting pressure block, a screw and a knob. The knob is turned manually to make the screw move spirally and drive the adjusting pressure block to move inside the support sleeve, so that the adjusting pressure block moves inside the support sleeve and adjusts the squeezing effect on the spring. At the same time, the adjusting pressure block can limit the position of the support rod moving inside the support sleeve, so that the degree of squeezing the rubber shock absorber by the upper flange and the lower flange can be adjusted, thereby adjusting the elastic force value. At the same time, the spring can increase the elastic force between the upper flange and the lower flange.

[0014] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can adjust the degree of squeezing the rubber shock absorber between the upper flange and the lower flange, so that the elastic force value of the rubber shock absorber can be adjusted, thereby improving the construction effect on the engineering machinery.

The interior of the support sleeve 5 rotates, and a screw 9 is provided on the top thread of the support sleeve 5. The lower end of the screw 9 is rotatably connected to the top of the adjusting pressure block 8, and a knob 10 is fixedly provided on the upper end of the screw 9. When the elastic force value needs to be adjusted, the knob 10 is turned manually to make the screw 9 move spirally and drive the adjusting pressure block 8 to move inside the support sleeve 5, so that the adjusting pressure block 8 moves inside the support sleeve 5 and adjusts the squeezing effect on the spring 7.
