Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder oil replenishment, in particular to a double-cylinder automatic oil replenishment balancing device. Background Art

[0002] The oil cylinder is a hydraulic cylinder. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of ​​the piston and the pressure difference on both sides. It is mainly used in places where heavy objects need to be supported for a long time. It can still support heavy objects when the oil pressure is removed. It is safe and reliable and can be used underwater. It is single-acting and load-retracting. The self-locking nut makes the load safer, especially in large-scale projects. It is an easy-to-operate control and self-locking jack. It is designed with a safety pressure maintaining device and a built-in pressure relief valve to prevent overload to protect the self-locking jack for safe operation. The oil cylinder will inevitably leak oil during use, so it needs to be refilled regularly.

When the piston of the first hydraulic cylinder moves upward to the dead point, the interface between the auxiliary hydraulic pipe and the first hydraulic cylinder is located below the piston. The one-way valve allows the first hydraulic cylinder to deliver hydraulic oil to the second hydraulic cylinder, and the opening pressure of the one-way valve is less than the working pressure of the hydraulic cylinder. The technical effects and advantages of the utility model: automatic oil replenishment to ensure that the stroke of the dual hydraulic cylinders is always the same.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] like Figure 4 As shown, in another embodiment of the utility model, the oil pipe 5 includes an oil pipe base 501, and the oil pipe base 501 is provided with an oil storage device 502 and two second threaded holes 503, and a second oil delivery groove 504 is provided between the two second threaded holes 503;

[0025] The second threaded hole 503 is provided with a connecting bolt 505, and the connecting bolt 505 is provided with a third oil delivery groove 506 and a fourth oil delivery groove 507. An oil delivery hole 508 is provided on one side below the connecting bolt 505. When it is necessary to provide power to the two oil cylinders, the oil storage device 502 is first started, and the oil storage device 502 allows the oil to enter the third oil delivery groove 506 of the connecting bolt 505, and then the oil enters the second oil delivery groove 504 through the third oil delivery groove 506, and then the oil enters the second oil delivery groove 504 through the second oil delivery groove 508. The oil groove 504 allows the oil to enter another third oil groove 506 of a connecting bolt 505, and then the oil enters the fourth oil groove 507 through the third oil groove 506. Then the oil in the fourth oil groove 507 enters the first oil groove 3 through the oil hole 508, and then enters the inner cavity of the cylinder 2 through the first oil groove 3, thereby providing power for the two cylinders at the same time, greatly saving installation time and installation complexity. At the same time, the two cylinders can also achieve more stable rising kinetic energy and stability.

[0026] The working principle of this double cylinder automatic oil replenishment balancing device:

[0027] When in use, first fix the bottom sleeve 6 and the upper sleeve 10 to the designated mechanism, then start the oil storage device 502, and let the oil enter the third oil delivery groove 506 of a connecting bolt 505 through the oil storage device 502, then let the oil enter the second oil delivery groove 504 through the third oil delivery groove 506, let the oil enter the third oil delivery groove 506 of another connecting bolt 505 through the second oil delivery groove 504, then let the oil enter the fourth oil delivery groove 507 through the third oil delivery groove 506, and then the oil in the fourth oil delivery groove 507 enters the first oil delivery groove through the oil delivery hole 508. In the specially processed oil circuit block composed of the groove 3 and the first threaded hole 4, the oil gradually enters the inner cavity of the cylinder 2 when passing through the first oil delivery groove 3, and the oil gradually squeezes the piston 9 to move the piston 9, and the piston 9 drives the piston rod 8 to move, so that the piston rod 8 gradually moves along the trajectory of the guide sleeve 7, so that the cylinder performs an ascending operation. Through the specially processed oil circuit block and the connecting bolt 505 in the lower cavity, one oil pipe 5 can provide power for two oil cylinders at the same time, which greatly saves the installation time and complexity of the installation. At the same time, the two oil cylinders can also achieve more stable ascending kinetic energy and stability.
