A hydraulic three-piston balance buffer

Abstract

The invention discloses a hydraulic three-piston balance buffer. A first oil cavity as a cylindrical cavity body is formed in the upper part of the buffer; three supporting legs are distributed under the oil cavity; a second oil cavity is arranged at the top end of each supporting leg; a cover plate is mounted at the upper end of the first oil cavity; the second oil cavities are communicated with the first oil cavity through pressure relief devices; and an oil filling hole is formed in the side surface of the first oil cavity. According to the hydraulic three-piston balance buffer, a supporting surface for a hard foreign material is provided at the uneven or local part, the hydraulic buffer is applied as a base foot of a mobile house, the pressure is relieved through load limit, and an adjacent supporting piston is started when the pressure intensity of a direct contact point is sharply increased so as to achieve the purpose of load balance; the defect of deformation caused by non-uniform stress of the base foot of the mobile house is improved, the base foot and the supporting surface of the mobile house are protected, and the service life of the base foot of the mobile house is prolonged; and the hydraulic three-piston balance buffer is suitable for moving or mounting large equipment such as containers and the like.

Description

technical field [0001] The invention belongs to the field of engineering construction, and in particular relates to a hydraulic three-piston balance buffer. Background technique [0002] Now when the prefabricated house is hoisted in place on site, there is always a sequence in which the support points of the foundation feet at the bottom of the prefab house touch the ground, and the force on each footing is always unbalanced. The first contact point receives a huge impact force instantly, And because the ground may be uneven, the support point and the ground are often in point contact, which not only makes the footing easy to be damaged due to force problems, but also causes unfavorable conditions for construction due to damage to the ground contact point. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic three-piston balance buffer for the deficiencies of the above-mentioned prior art, which can autom...
