Anti-shearing spring absorber

Abstract

The invention discloses an anti-shearing spring absorber. The anti-shearing spring absorber comprises a spring body, an upper cover, a lower cover, a bottom plate, a limiting plate, stand plates and positioning bolts. The lower surface of the lower cover is fixed to the center of the bottom plate through bolts, and mounting gaps are formed in the left side and the right side of the bottom plate. The bottom plate can be locked on a mounting face through the mounting gaps. Two mounting holes symmetric about the center of the spring body are formed in each stand plate. The two positioning bolts penetrate through the mounting holes in the stand plates and are locked through nuts, the positioning bolts are located on the two sides of the spring body, and the outer sides of the positioning boltsare sleeved with linings. The top of the upper cover and the limiting plate are locked through a locking screw rod, the left side and the right side of the limiting plate are turned over downwards and are provided with rolled edges, the rolled edges sleeve the linings, the limiting plate can move up and down, left-right motion of the limiting plate is blocked by the rolled edges of the limiting plate, and the front-back motion of the limiting plate is blocked by the friction force of the linings and the stand plates. The anti-shearing spring absorber is simpler in structure, cost is reduced,and the shear force preventing effect of the spring absorber is improved.

Description

technical field [0001] The invention belongs to the field of spring shock absorbers, in particular to an anti-shear spring shock absorber. Background technique [0002] Spring shock absorbers are widely used in air conditioners, automobiles, thermal power plants, chemical plants, and steel plants, and can effectively control vibrations and swings of various frequencies. Ordinary spring dampers are only aimed at damping vibration in the vertical direction, while in mobile and transportation equipment, or areas where earthquakes often occur, the spring damper will be subjected to shear force, or lateral force, causing the spring to absorb vibration The horizontal bearing capacity of the device is poor, and there are potential safety hazards. Conventional anti-shear spring shock absorbers include JM3 type, which uses columns on both sides of the spring for lateral blocking; also includes GXSYM type, which uses a box-type structure. Others include mounting bolts on both sides,...

AI Technical Summary

Problems solved by technology

[0003] 1. The cost is high, and more steel plates need to be installed;

[0004] 2. The installation is complicated, and the balance on both sides needs to be adjusted, and sometimes the spring shock absorber needs to be lifted when installing up and down;

[0005] 3. Some products have poor anti-shear force effect, and the contact parts are small, easy to fall off or torn off when subjected to large lateral force
