Abstract
The utility model discloses a reciprocating type movable composite oil cylinder which comprises a first oil cylinder body (1) and a second oil cylinder body (4) which are connected to form a whole body, wherein the first oil cylinder body is provided with a rod cavity (1-2) which is communicated with a rodless cavity (4-1) of the second oil cylinder body; and a rodless cavity (1-4) of the first oil cylinder body is communicated with a rod cavity (4-3) of the second oil cylinder body. Compared with the prior art, the reciprocating type movable oil cylinder disclosed by the utility model is simple in structure; hydraulic oil simultaneously acts on the rod cavity of one oil cylinder and the rodless cavity of the other oil cylinder and the action area of pressure oil is increased, so that greater load can be pushed under the condition that the pressure is identical; and under the load is identical, the work pressure of the system can be reduced. Particularly, under the condition that the flow is identical, the consistency of the movement velocity in the forward direction with the movement velocity in the backward direction can be realized, which is very important for the hydraulic system which has adjustable same forward and backward speed and is favorable for simplifying the system structure.
Description
Technical field
The present invention relates to the composite oil cylinder of a kind of hydraulic jack, particularly a kind of reciprocating type constant speed movement.
Background technique
At present, in reciprocating motion type mechanism, adopt commonly used the having of hydraulic jack: 1, double-action single-piston rod oil cylinder, 2, the double-action double rod cylinder.
Under the oil pump feed pressure situation identical with flow; In the 1st kind of situation, the active force that fluid gets into the oil cylinder rodless cavity generation gets into the active force that cylinder rod chamber produces greater than fluid, the movement velocity that the movement velocity that fluid entering cylinder rod chamber produces produces greater than fluid entering oil cylinder rodless cavity; During system works; If the liquid-conveying amount of oil hydraulic pump is identical, then there is fast, the slow situation of another direction movement velocity of a direction movement velocity, if will improve motion conditions; If oil hydraulic pump is carried liquid with same pressure; Big, a little situation of another direction promotion pressure of direction motion promotion pressure then appears; Address the above problem the differential connection of common employing, motion conditions is improved, but control mechanism wants complicated a lot of relatively.For the 2nd kind of situation; Modal is equal diameter double-action double rod cylinder, can realize that oil cylinder side-to-side movement speed equates, but owing to the useful area of fluid effect reduces; The active force that oil cylinder produces reduces, and the pressure that system produces when promoting heavy load just needs bigger.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model is to provide, and back and forth movement speed is equated, the reciprocating type mobile composite oil cylinder that thrust is balanced.
The purpose of the utility model realizes through following structure: comprise connecting two cylinder bodies arranged side by side of all-in-one-piece; I.e. first cylinder body (1) and second cylinder body (4); Be provided with first oil cylinder piston (1-3) in first cylinder body (1); One end of first oil cylinder piston (1-3) is equiped with the first overhanging oil cylinder piston bar (1-1); And first oil cylinder piston (1-3) is with being separated into the first cylinder body rodless cavity (1-4) and the first cylinder body rod chamber (1-2) in first cylinder body (1); Be provided with second oil cylinder piston (4-2) in second cylinder body (4); One end of second oil cylinder piston (4-2) is equiped with the second overhanging oil cylinder piston bar (4-4), and second oil cylinder piston (4-2) is characterized in that being separated into the second cylinder body rod chamber (4-1) and the second cylinder body rodless cavity (4-1) in second cylinder body (4): the piston rod of said first cylinder body (1) and second cylinder body (4) in the opposite direction; And the first cylinder body rod chamber (1-2) is connected with the second cylinder body rodless cavity (4-1), and the first cylinder body rodless cavity (1-4) is connected with the second cylinder body rod chamber (4-1).
Compared with prior art; The utility model is not only simple in structure; Because hydraulic oil acts on the rod chamber of one of them oil cylinder and the rodless cavity of another oil cylinder simultaneously, has increased the pressure oil active area, therefore under the identical situation of pressure, can promote bigger load; Under the identical situation of load; Can reduce system works pressure; Particularly; Can realize that under the identical situation of flow the movement velocity of advancing with the both direction that falls back is equal, this is extremely important for requiring the equal and adjustable hydraulic system of forward and reverse speed, helps simplied system structure.
