Background technique
At present, in engineering, use two cylinder systems, general two oil cylinders in parallel with cylinder diameter.The defective of this system is that just can not to protect two oil cylinder piston bars synchronously flexible, loads especially when different, and two flexible differences of oil cylinder piston bar are big, cause system's knockdown, can not work.So adopt in the existing machinery two oil cylinder working strokes are detected, compare, the utilization electric-hydraulic proportion is controlled and is adjusted synchronously.But this system architecture complexity, the cost height.In addition, a kind of employing is arranged, be difficult to the active force unanimity of strict guarantee two oil cylinders equally by a piston oil-cylinder and the synchronizer that plunger cylinder is in series.
Summary of the invention
For overcoming the deficiencies in the prior art, it is a kind of synchronously with the two cylinder systems of power that the utility model provides.Need not device for detecting distance of travel, can guarantee two group oil cylinder the piston rods synchronous and same power of stretching.
The technical solution of the utility model is: it comprises the series connection lock unit of being made up of two large and small oil cylinders, the rod chamber of the large tank in each series connection lock unit and the rodless cavity UNICOM of small oil tank, the sectional area of its large tank rod chamber equates that with the sectional area of small oil tank rodless cavity the stroke of two oil cylinder piston bars equates simultaneously.Again with two identical series connection lock unit parallel connections, and the small oil tank of the large tank that makes each unit and another unit intersects parallel configuration, constitutes two synchronization group.
The piston rod end that its further scheme is the large and small oil cylinder in each synchronization group is connected by joiner.
The beneficial effects of the utility model are, need not under the detection device situation, just can make two synchronization group piston rod synchronization motions, and bearing capacity equates.Simple in structure, reliability height, low cost of manufacture.

Embodiment
As shown in Figure 1.In the series connection lock unit that constitutes by 5 large tank assemblies and 10 small oil tank assemblies, according to hydraulic pressure isometric(al) synchronization principles, set 7 large tank rod chamber sectional areas and equal 11 small oil tank rodless cavity sectional areas, and 8 large tank piston rods are equated with 13 small oil tank piston rod strokes.Thereby reach the synchronous effect of two oil cylinder strokes, but the amount of force of two oil cylinder piston bars is unequal.Wherein the radius of 13 small oil tank piston rods is determined by the small oil tank structure.
As shown in Figure 2.In order to satisfy the requirement that two 16 mechanical arm work are synchronous and bearing capacity equates, two 3 large tank rodless cavity hydraulic fluid ports and the parallel connection of two 2 small oil tank rod chamber hydraulic fluid ports in the series connection lock unit that two design parameters of Fig. 1 are all equal, and 5 large tank assemblies and 10 small oil tank assembly cross-over configuration and parallel assembling with two unit reconstitute two synchronization group in parallel.In the present embodiment, 5 large tank assemblies are assemblied in 16 mechanical arm inboards, 10 small oil tank assemblies are assemblied in the 16 mechanical arms outside, are decided by stressing conditions.Stressed simultaneously then can be different.
As shown in Figure 3.8 large tank piston rod ends in two synchronization group in parallel that reconstitute and 13 small oil tank piston rod ends can be connected with 17 joiners, connect with 16 mechanical arms by 17 joiners again, its interface is the equinoctial point of the pairing moment of large and small oil cylinder.This scheme is specially adapted to the connection of hinge type mechanical arm.17 joiners preferably are vertical the connection with two piston rod ends.
As shown in Figure 4.In two series connection lock units that 5 large tank assemblies and 10 small oil tank assemblies are formed, one 18 equilibrium valve of grafting between 7 large tank rod chambers in 1 large tank rod chamber and small oil tank rodless cavity UNICOM replenishes and drain tap is connected with one of them lock unit and 11 small oil tank rodless cavity UNICOM oil pipes; Replenish and drain tap grafting another 18 equilibrium valves between 7 large tank rod chambers in the lock unit and 11 small oil tank rodless cavity UNICOM oil pipes of connecting with another in 15 large tank rod chambers and small oil tank rodless cavity UNICOM.Two 18 equilibrium valves are two 7 large tank rod chambers and the replenishing and oil drain valve of 11 small oil tank rodless cavities in the series connection lock unit.This scheme is applicable to when system works is asynchronous, can replenish with drain tap, 15 large tank rod chambers and small oil tank rodless cavity UNICOM by 1 large tank rod chamber and small oil tank rodless cavity UNICOM and replenish and drain tap, pilot pressure oil goes out, goes into, and adjust system work is synchronous.
As shown in Figure 5.Be connected in series 19 equilibrium valves after the parallel connection of two 6 large tank rodless cavity inlet and outlet of fuel channel and between the 3 large tank rodless cavity hydraulic fluid ports.When this scheme preferably was applicable to every oil cylinder non-standard state work, motion steadily when weight was descended.
As shown in Figure 6.6 large tank rodless cavities in two 5 large tank assemblies and the oil inlet and outlet on the 7 large tank rod chamber casing walls are installed 20 bidirectional hydraulic locks.This scheme is a string oil between each oil cylinder during for anti-locking system off working state, influences systems work synchronized.
