Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of hydraulic cylinder devices, and particularly relates to a booster structure and a hydraulic cylinder device. BACKGROUND

[0002] The hydraulic cylinder device is a power device for converting hydraulic energy into mechanical energy and realizing linear reciprocating motion or swing motion. The hydraulic cylinder device is widely used in the fields of engineering machinery, automobile industry, metallurgical industry, agricultural machinery, metal processing and aerospace, etc. The hydraulic cylinder device is composed of a cylinder main body and a booster, etc. The booster is connected with the cylinder main body.

[0003] The booster of the related art comprises a high-pressure cylinder, a low-pressure cylinder, an outlet nozzle, a discharge nozzle, an inlet nozzle, a pressure relief valve group, a check valve group, a safety valve, a discharge valve, a low-pressure cylinder inlet valve, a high-pressure cylinder inlet valve, an operating handle, a high-pressure oil pipe and a hydraulic valve plate. The high-pressure cylinder and the low-pressure cylinder are in communication with each other, share a same piston rod and a same piston, and the center lines of the high-pressure cylinder and the low-pressure cylinder are on a same straight line. The inlet of the pressure relief valve group and the outlet of the check valve group are communicated. The outlet of the pressure relief valve group is connected with the discharge nozzle through a pressure relief pipe. The inlet of the check valve group is connected with the inlet nozzle through the high-pressure oil pipe. The outlet of the check valve group is connected with the safety valve and the outlet nozzle. The hydraulic valve plate is arranged at the end of the low-pressure cylinder. A filter screen, a flow control valve, the operating handle, the discharge valve, the low-pressure cylinder inlet valve and the high-pressure cylinder inlet valve are arranged on the hydraulic valve plate. The inlets of the low-pressure cylinder inlet valve and the high-pressure cylinder inlet valve are connected with the inlet nozzle through the high-pressure oil pipe. The inlet of the discharge valve is connected with the low-pressure cylinder, and the outlet is connected with the discharge nozzle. The above-mentioned booster is disclosed in Chinese Patent No. CN103994108A.

[0004] When the operating handle is lifted, the high-pressure cylinder inlet valve and the discharge valve are opened at the same time, and the low-pressure cylinder inlet valve is in a closed state. At this time, the system pressure provided by the existing emulsion pump station (i.e. hydraulic station) in the coal mine is respectively introduced into the high-pressure cylinder and the cutter through the high-pressure oil pipe and the check valve group. The system pressure introduced into the high-pressure cylinder pushes the piston rod and the piston to move in the direction of the low-pressure cylinder. At this time, the gas and liquid in the inner cavity of the low-pressure cylinder are discharged from the discharge valve. The pressure provided by the hydraulic station fills the high-pressure cylinder and the cutter, and the pressure in the high-pressure cylinder and the cutter is equal to the pressure of the hydraulic station. Then, the operating handle is pressed, the discharge valve and the high-pressure cylinder inlet valve are closed at the same time, and the low-pressure cylinder inlet valve is in an open state. The pressure of the hydraulic station is transferred into the low-pressure cylinder and pushes the piston to move in the direction of the high-pressure cylinder, pushes the piston rod into the high-pressure cylinder, and squeezes the liquid in the inner cavity of the high-pressure cylinder to the cutter. After the piston rod squeezes the liquid in the inner cavity of the high-pressure cylinder out, the check valve group is in a reverse push closed state and a forward push open state, which prevents the liquid from flowing back, and the liquid can only be pushed into the cutter for pressure boosting.

[0005] However, since the pressure provided by the hydraulic station is needed for the supercharger to perform the supercharging process, the supercharger is connected to the hydraulic station, the system pressure provided by the hydraulic station enters the high-pressure oil cylinder and the cutout through the high-pressure oil pipe and the check valve group, the high-pressure oil pipe and the check valve group and other components jointly constitute a hydraulic pipeline, so that the supercharger and the hydraulic station are connected through the hydraulic pipeline, and the hydraulic station and the hydraulic pipeline jointly act on the supercharger to perform the supercharging process, resulting in that the supercharger needs to use more components to perform the supercharging process, thereby increasing the operation cost of the supercharger for performing the supercharging process.

[0037] In the embodiment, the gas source device is an air compressor. The oil inlet cavity 150 is used for guiding the hydraulic oil to be introduced. The oil outlet cavity 160 is used for guiding the hydraulic oil to be discharged. The one-way oil inlet assembly 400 is used for allowing the oil inlet passage 121 to be one-way oil inlet, that is, the one-way oil inlet assembly 400 can only guide the hydraulic oil from the oil inlet cavity 150 to the second piston cavity 120 through the oil inlet passage 121, and cannot guide the hydraulic oil from the second piston cavity 120 to the oil inlet cavity 150 through the oil inlet passage 121, so that the hydraulic oil flows in one direction.

[0051] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] Since the piston body 300 is used to abut against the end cover body 200 when sliding to a predetermined position in the first piston cavity 110, at this time, the piston body 300 is located at the rightmost end in the first piston cavity 110. When the piston body 300 is located at the leftmost end in the first piston cavity 110, the piston body 300 abuts against the radial inner wall of the first piston cavity 110;

[0053] In the working process of the booster structure 10, the piston body 300 is at the leftmost end of the first piston cavity 110, at this time, the second gas port 140 is connected to the gas source device, so that the gas enters the first piston cavity 110 along the second gas port 140, and the gas acts on the piston body 300 to make the piston body 300 move right along the first piston cavity 110, so that the second piston cavity 120 is enlarged to form a negative pressure state, so that the second piston cavity 120 is at low pressure, at this time, the oil outlet channel 122 is closed under the action of the one-way oil outlet assembly 500, and the oil inlet channel 121 is opened under the action of the one-way oil inlet assembly 400, so that the hydraulic oil enters the second piston cavity 120, when the piston body 300 moves to the rightmost end of the first piston cavity 110, the oil inlet process of the booster structure 10 is completed; then, the first gas port 130 is connected to the gas source device, so that the gas enters the first piston cavity 110 along the first gas port 130, and the gas acts on the piston body 300 to make the piston body 300 move left along the first piston cavity 110, so that the second piston cavity 120 is reduced to form a high pressure state, so that the second piston cavity 120 is at high pressure, at this time, the oil inlet channel 121 is closed under the action of the one-way oil inlet assembly 400, and the oil outlet channel 122 is opened under the action of the one-way oil outlet assembly 500, so that the hydraulic oil is output from the second piston cavity 120 to the oil outlet cavity 160 under high pressure, when the piston body 300 moves to the leftmost end of the first piston cavity 110, the oil outlet process of the booster structure 10 is completed;
