Problems solved by technology

[0006] At that time, the above three methods had the following defects. Method 1 relied on manual experience to detect and adjust, the error was relatively large, and the reliability was not high.
Method 2 may need to add a lot of electrical equipment, which is costly and complicated to install, and the reliability is not high
Method 3 is quite reliable, but the cost is too high, and it is only suitable for extremely high precision without considering the cost

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0022] Such as Figures 1 to 3 As shown, a double hydraulic cylinder automatic synchronization system, including: the first hydraulic cylinder 1, the second hydraulic cylinder 2 with the piston rods moving in the same direction, and the piston rod used to detect the synchronization of the first hydraulic cylinder piston rod and the second hydraulic cylinder piston rod Feedback handle 3 that stretches out the difference in length during movement; the first hydraulic cylinder 1 is stretched and retracted by the first cylinder operating handle 11 through the control valve, and the second hydraulic cylinder 2 is stretched by the second cylinder operating handle 21 through the control valve .

[0023] The piston rod of the first hydraulic cylinder 1 is connected to the feedback handle 3 through the first connection device, the piston rod of the second hydraulic c...

Abstract

A double-hydraulic-oil-cylinder automatic synchronizing system comprises a first hydraulic oil cylinder, a second hydraulic oil cylinder and a feedback device, wherein a piston rod of the first hydraulic oil cylinder and a piston rod of the second hydraulic oil cylinder move in the same direction, the feedback device is used for detecting the difference of the stretching lengths of the piston rodof the first hydraulic oil cylinder and the piston rod of the second hydraulic oil cylinder during synchronous movement, the feedback device guides feedback compensation oil into a piloted oil way tocontrol a rodless cavity of the hydraulic oil cylinder with the large piston rod stretching length, and the synchronous action of the two hydraulic oil cylinders is achieved by reducing the stretchingspeed of the piston rod of the hydraulic oil cylinder. The double-hydraulic-oil-cylinder automatic synchronizing system is low in cost, reliable in control, convenient to install and detect and capable of achieving the effect of automatic synchronization of the double hydraulic oil cylinders.

Description

technical field [0001] The invention relates to an automatic synchronization system of double hydraulic oil cylinders. Background technique [0002] In the process of mechanical installation and work, in many cases, double oil cylinders are used to push a certain working device, which can not only ensure sufficient thrust, but also generate a small angle through the relative movement of the oil cylinders. However, how to ensure the synchronization of the two oil cylinders when they move in the same direction has become a major problem when the dual oil cylinder system works. For example: the mast cylinders of all piling machines use a double cylinder system. During the process of mast erection and upturning, the two column cylinders must be extended or retracted at the same speed. If the synchronization of the oil cylinder cannot be guaranteed at this time, the column will tilt in one direction to the left or right, damaging the structural parts. If the operator does not n...
