[0002] The hydraulic hoist is generally composed of a hydraulic system and a hydraulic cylinder. Under the control of the hydraulic system, the inner wall of the piston in the hydraulic cylinder makes axial reciprocating motion, thereby driving the connecting rod and the gate connected to the piston to make linear motion to achieve the purpose of opening and closing the orifice. The hydraulic hoist is generally installed at the river gate and is in an outdoor environment.

[0012] Beneficial effects of the utility model:

[0013] (1) In the utility model, when the hydraulic oil of the hydraulic opening and closing machine of the outdoor gate is low and an emergency task is required to open and close the gate, the hydraulic oil is urgently injected and the cylinder is started. After the cylinder is started, it extends and drives the swing rod to tilt upward. The swing rod drives the pull rod and the pumping valve to move downward. At this time, under the action of oil pressure, the valve plate on the pumping valve flips upward, and the hydraulic oil moves upward through the opening after the valve plate flips. The pumping valve continues to move downward, so that more hydraulic oil is on the pumping valve until the swing rod contacts the top of the slot. The cylinder drives the rocker arm to reset, and the pumping valve moves upward at this time. Under the action of oil pressure, the valve plate on the pumping valve is tightly closed, driving the hydraulic oil in the oil guide pipe to move upward to the oil delivery pipe, and finally enters the oil filling port of the hydraulic gate to complete the filling. During the hydraulic oil filling process, the hydraulic oil is filled under the quantitative extension and reset of the cylinder. Therefore, as long as the amount of oil in the hydraulic oil tank is constant, the filling amount of the hydraulic oil will be obtained by obtaining the frequency of the reciprocating extension of the cylinder, which is conducive to the accurate filling of the hydraulic oil.

[0014] (2) In the present invention, in an emergency situation outdoors without power supply, when it is necessary to fill the hydraulic oil of the hydraulic gate opener, the pin is first removed from the positioning U-shaped rod, and then the positioning U-shaped rod is removed from the rocker arm, so that the pin seat is separated from the rocker arm, that is, the rocker arm is not controlled by the extension and reset of the cylinder, and then the handle is held by hand to press and lift the handle in the vertical direction, which has the same effect as the reciprocating extension and compression of the cylinder, thereby completing the extraction and filling of the hydraulic oil. The connecting rod type filling method has the advantage of saving labor. BRIEF DESCRIPTION OF THE DRAWINGS

The cross-sections of the upper and lower groups of O-rings 17 together form a "3" shape. The outer side of the upper end of the O-ring 17 is in close contact with the inner wall of the oil guide pipe 8. In the process of the pumping valve 10 reciprocating up and down, the O-ring 17 is completely fitted with the inner wall of the oil guide pipe 8, and the sealing is achieved in a completely fitted manner, thereby ensuring the sealing between the pumping valve 10 and the one-way valve 9, and achieving the purpose of rapid oil extraction;
