Problems solved by technology

[0003] However, in some places of use, it is required that the hydraulic cylinder can be locked in one direction, that is, the piston rod can move freely to one side, while the other side cannot move freely. This method is currently mainly realized through the linkage of multiple sets of solenoid valves, and the oil circuit and control are complicated

Embodiment Construction

[0013] The present invention will be further described now in conjunction with accompanying drawing.

[0014] like figure 1 and figure 2 As shown, a safety lock hydraulic cylinder includes a solenoid valve 5 , a cylinder body 1 , a check valve and a cylinder cover 5 .

[0015] The cylinder body 1 is provided with a piston hole, a first oil hole 11, a second oil hole 12 and a valve seat 15. The piston hole is arranged along the axis and is a through hole. The first oil hole 11 and the second oil hole 12 are arranged in the cylinder Both ends of the body 1 communicate with the piston hole. Solenoid valve 5 is installed on valve seat 15, and valve seat 15 is provided with valve hole 16, the 3rd oil hole 17 and the 4th oil hole 18, check valve is installed in valve hole 16, and the two ends of valve hole 16 respectively pass through The oil pipe 6 communicates with the first oil hole 11 and the second oil hole 12, the third oil hole 17 and the fourth oil hole 18 are respective...

Abstract

The invention relates to a hydraulic cylinder, in particular to a safety lock hydraulic cylinder which comprises an electromagnetic valve, a hydraulic oil cylinder body, a one-way valve, a cylinder cover, a two-way piston rod and a piston. The cylinder body is provided with a piston hole, a first oil hole and a second oil hole, the first oil hole and the second oil hole are communicated with the piston hole and located at the two ends of the cylinder body, the cylinder body is further provided with a valve seat, and the valve seat is provided with a valve hole communicated with the first oil hole and the second oil hole and a third oil hole and a fourth oil hole which are communicated with the first oil hole and the second oil hole respectively. The third oil hole and the fourth oil hole are respectively connected with the electromagnetic valve; the one-way valve is mounted in the valve hole; the cylinder covers are fixed at two ends of the piston hole; the two-way piston rod is slidably inserted into the cylinder cover; the piston is fixed on the two-way piston rod and is movably inserted into the piston hole; and the hydraulic cylinder is filled with hydraulic oil. According to the safety lock hydraulic cylinder, the one-way valve is integrated in the hydraulic cylinder, the one-way locking function can be achieved through the electromagnetic valve, an oil way and control are simple, the integration degree is high, the structure is simple, installation is convenient, and use is reliable.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to a safety lock hydraulic cylinder. Background technique [0002] A double-rod hydraulic cylinder is a hydraulic cylinder with piston rods on both sides of the piston. It is generally driven by two-way hydraulic pressure and can realize constant-velocity reciprocating motion. [0003] However, in some places of use, it is required that the hydraulic cylinder can be locked in one direction, that is, the piston rod can move freely to one side, while the other side cannot move freely. This method is currently mainly realized through the linkage of multiple sets of solenoid valves, and the oil circuit and control are complicated . Contents of the invention [0004] In order to solve the above problems, the present invention provides a safety lock hydraulic cylinder with simple oil circuit and control, high integration and simple structure. The specific technical solution is: [0005] A safet...
