Abstract
For a hydraulic balancer for prefabricated house footing, comprise the seal chamber that is filled with hydraulic oil, seal chamber is provided with oil filler point, and described seal chamber is provided with multiple groove, and piston is positioned at groove and is that groove slides, and a piston part is exposed outside seal chamber.A kind of hydraulic balancer for prefabricated house footing of the present invention, has the supporting surface of hard foreign matter, applies the footing of this hydraulic balancer as prefabricated house, pass through hydraulic pressure transfer in out-of-flatness or local.When foremost contacting position pressure raises, transmitting force, to adjacent pistons, reaches the object of balancing load.
Description
Technical field
A kind of hydraulic balancer for prefabricated house footing of the present invention.
Background technology
When prefabricated house on-site hoisting is in place, because ground may occur out-of-flatness, bottom prefabricated house, contacting to earth of the footing strong point has sequencing, and each footing is stressed always unbalanced.Be often point cantact between the footing strong point and ground, the footing strong point that contacts to earth at first, instantaneously by larger impact force, just easily causes the destruction of footing damage and ground contact points.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of hydraulic balancer for prefabricated house footing, having the supporting surface of hard foreign matter in out-of-flatness or local, applying the footing of this hydraulic balancer as prefabricated house, pass through hydraulic pressure transfer.When foremost contacting position pressure raises, transmitting force, to adjacent pistons, reaches the object of balancing load.
Above-mentioned purpose of the present invention is realized by such technical scheme: a kind of hydraulic balancer for prefabricated house footing, comprise the seal chamber that is filled with hydraulic oil, seal chamber is provided with oil filler point, described seal chamber is provided with multiple groove, piston is positioned at groove and is that groove slides, and a piston part is exposed outside seal chamber.
Described seal chamber is cavity structure, which is provided with seal cover board, and seal cover board is as supporting surface, and described seal chamber inside is provided with slider, and seal chamber is divided into multiple groove by slider.Be provided with three columniform grooves in described seal chamber, three pistons lay respectively in groove.
Described seal cover board is provided with fixing hole.
A kind of hydraulic balancer for prefabricated house footing of the present invention, the discontinuity equalization of each position point of the prefabricated house of improving over footing and the deformation defect that causes, protection prefabricated house footing and support ground, improves the application life of prefabricated house footing.From exfactory inspection, field observation and user's Long-Time Service feedback, indices is all better than traditional prefabricated house footing.The hydraulic balancer of prefabricated house footing, at container, main equipment or to the equipment having damping to require when moving, can use, have great dissemination.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 5, a kind of hydraulic balancer for prefabricated house footing, comprise the seal chamber 1 that is filled with hydraulic oil, seal chamber 1 is provided with oil filler point 6, described seal chamber 1 is provided with multiple groove 2, piston 3 is positioned at groove 2 and is that groove 2 slides, and it is outer as support column that piston 3 part exposes seal chamber 1.Described seal chamber 1 is cavity structure, which is provided with seal cover board 4, seal cover board 4 is as supporting surface, described seal chamber 1 inside is provided with slider 5, slider 5 is seal chamber 1 ledge, top and seal cover board 4 have a spacer segment distance, and described spacing distance, groove 2 form the circulation passage of hydraulic oil.Slider 5 and the same material of seal chamber 1 shell, can be produced by mould injection molding during making.Seal chamber 1 is divided into multiple groove 2 by slider 5.Described seal cover board 4 four angles have fixing hole 7.Fixing hole 7 is for being fixed on prefabricated house footing by securing member by this hydraulic balancer.
The present embodiment preferentially adopts in seal chamber 1 and is provided with three columniform groove structures, and three pistons lay respectively in groove.Seal chamber 1 side has oil filler point 6, facilitates injection liquid force feed.Piston 3 part exposes seal chamber 1 as footing, lift by crane in process in place at prefabricated house, when any one footing contacts to earth, wherein some pistons are stressed at first, now, this piston adduction, make seal chamber 1 corresponding part pressure increase, two other piston is under the effect of hydraulic oil, protruding, until bear identical support force, reach three pistons simultaneously by equilibrium of forces.The piston first contacting supporting surface is protected by release, protects prefabricated house footing and piston simultaneously.
