Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a rubber shock absorber for the outriggers of the lifting crane to protect the construction ground from damage, which has the advantages of protecting the construction ground from damage and can cooperate with the oil cylinder to adjust the balance, and solves the existing problems. The outriggers use hydraulic cylinders to directly contact the ground hard, thus damaging the ground

The invention relates to the technical field of rubber shock absorption, and discloses a hoisting crane supporting leg rubber shock absorber for preventing a construction ground from being damaged. The rubber shock absorber comprises a movable supporting leg, wherein a lifting oil cylinder is fixedly mounted at the lower left end of the movable supporting leg, a connecting rod is fixedly mounted at the lower end of the lifting oil cylinder, a top cover plate is fixedly mounted at the lower end of the connecting rod by means of a fixing base, threaded holes which are evenly distributed are formed in the top cover plate, a stabilizing rod is fixedly mounted at the lower end of the top cover plate, and the stabilizing rod can be fixed in a movable groove by means of a limiting block to move up and down. According to the rubber shock absorber, the surfaces of the stabilizing rod and a stabilizing rod base are sleeved with springs, when balance is adjusted before use, the lifting oil cylinder is controlled, the lifting oil cylinder drives the connecting rod to move, the connecting rod drives the stabilizing rod to move, and the limiting block at the lower end of the stabilizing rod moves in the movable groove, so that the top cover plate extrudes the springs to cooperate with the effect of rubber sheets, and then the influence of vibration generated in the construction process on the bottom surface is relieved.
Description
technical field [0001] The invention relates to the technical field of rubber shock absorption, in particular to a rubber shock absorber for the outrigger legs of a hoisting crane to protect the construction ground from damage. Background technique [0002] As an important type of shock absorber, rubber shock absorbers are widely used in various machinery, automobiles, transportation and aviation fields. Rubber has high elasticity and viscoelasticity, and compared with steel materials, rubber has a large elastic deformation , the modulus of elasticity is very small, etc. Compared with other shock absorbers, the rubber shock absorber has a freely determined shape, and the composition of the rubber formula can be adjusted to control the hardness, which can meet the requirements for stiffness and strength in all directions, and the rubber shock absorber The internal friction of the vibrator is large, which has the advantages of good shock absorption effect, which is conducive t...
