Abstract
Disclosed is a hydraulic pressure triple-piston equalizing buffer. The upper portion of the hydraulic pressure triple-piston equalizing buffer is an oil chamber which is a cylindrical cavity. Three supporting legs are distributed below the oil chamber, the top end of each supporting leg is provided with the oil chamber. The upper end of the oil chamber is provided with cover plate. The oil chambers are communicated with the oil chamber through a pressure relief device. The side face of the oil chamber is provided with an oil filler hole. The oil chamber applies a hydraulic buffer to be base legs of a mobile chamber in a supporting face which is uneven and has hard foreign matters in parts. By means of loading limit pressure relief, when the pressure of a straight contacting point rises sharply, the adjacent supporting pistons are started so as to achieve the aim of balancing load. Furthermore, the circumstance of transformation caused by uneven stress of the base legs of the mobile chamber can be improved, the base legs of the mobile chamber and the supporting face are protected, and service life of the mobile chamber is prolonged. The hydraulic pressure triple-piston equalizing buffer is suitable for move or installation of large scale equipment such as containers.
Description
Technical field
The utility model belongs to the engineering construction field, is specifically related to a kind of hydraulic pressure three piston equalizing buffers.
Background technology
Now when the prefabricated house on-site hoisting is in place, contacting to earth of the prefabricated house bottom footing strong point always has sequencing, and each footing is stressed always unbalanced, at first touchdown point moment the power that is hit very big, and because ground possibility out-of-flatness, the strong point and ground usually are to contact, so not only can so that footing owing to stressed problem is easily damaged, and can cause because the damage of ground contact point and the disadvantageous situation of constructing is occured.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art; and a kind of hydraulic pressure three piston equalizing buffers that provide; it can adjust to automatic dynamic the length of footing, the impact force when disperseing footing to land, footing and the supporting surface of protection prefabricated house when footing lands.
The purpose of this utility model is achieved in that
A kind of hydraulic pressure three piston equalizing buffers is characterized in that: part is an oil pocket on it, is distributed with 3 legs below the oil pocket, the top of each leg is provided with oil pocket, described oil pocket is communicated with oil pocket by pressure relief device, and the oil pocket side has oil filler point, and cover plate is equipped with in the upper end of oil pocket.
Described oil pocket is circular cylindrical cavity.
Described leg is piston.
Described pressure relief device is the double-direction relief valve.
The utility model has been obtained following technique effect:
The hydraulic pressure three piston equalizing buffers that the utility model adopts, at first, it is at out-of-flatness or the local supporting surface that hard foreign matter is arranged, use oil buffer as the footing of prefabricated house, by the limit for tonnage pressure release, when directly contact point pressure sharply raises, start the adjacent supports piston, reach the purpose of balancing load; Then, it has improved the situation of the deformation defect that prefabricated house footing in the past causes owing to the discontinuity equalization of each point, has protected prefabricated house footing and supporting surface, has improved the application life of prefabricated house footing; Again, it has the equipment of damping requirement to use at container, main equipment or when moving.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is top view of the present utility model;
Fig. 4 is lateral view of the present utility model.
The specific embodiment
Such as Fig. 1 Fig. 2 Fig. 3 and a kind of hydraulic pressure three piston equalizing buffers shown in Figure 4, part is an oil pocket 1 on it, is distributed with 3 legs 3 below the oil pocket 1, and the top of each leg 3 is provided with oil pocket 2, and cover plate 6 is equipped with in the upper end of oil pocket 1.Described oil pocket 2 is communicated with oil pocket 1 by pressure relief device 4, and oil pocket 1 side has oil filler point 5, and oil pocket 1 is circular cylindrical cavity, and leg 3 is piston, and pressure relief device 4 is the double-direction relief valve.
When the utility model uses, hydraulic pressure three piston equalizing buffer the first half are circular cylindrical cavities, the below is the oil pocket that is combined together by three pistons, the inner chamber of each piston is communicated with by the double-direction relief valve with the cavity that oils, the circular cylindrical cavity side has oil filler point, makes things convenient for the injection liquid force feed.Lift by crane in the process in place at prefabricated house; when any one footing contacts to earth; always there is one of them piston to contact at first supporting surface; at this moment; the pressure that this piston cavity is subject to increases; double-direction relief valve events, hydraulic oil enter the oiling machine chamber, and the pressure in the whole cavity that oils sharply increases; at this moment; two other double-direction relief valve also begins action, hydraulic oil is pressed in two other piston cavity, under the effect of hydraulic oil; two other piston that does not contact to earth outwards extends; reach three pistons and be subjected to simultaneously equilibrium of forces, the piston that contacts first supporting surface is protected by pressure release, has protected simultaneously prefabricated house footing and supporting surface.
