Description

Technical Field

[0001] This utility model relates to the field of hydraulic booster equipment technology, and in particular to a pneumatic hydraulic booster cylinder. Background Technology

[0002] Hydraulic booster cylinders are pressure boosting devices used when mechanical equipment encounters insufficient pressure during operation. They effectively increase the pressure of the equipment to ensure its normal operation. Most existing hydraulic booster cylinders achieve the boosting effect by connecting multiple cylinders side by side. This results in an increased cylinder volume, making them incompatible with existing machines and requiring external connections or welding, which leads to installation difficulties. Therefore, improvements are needed. Utility Model Content

[0003] The main purpose of this utility model is to propose a pneumatic-hydraulic booster cylinder, which aims to provide an easy-to-install pneumatic-hydraulic booster cylinder.

[0004] To achieve the above objectives, this utility model proposes a pneumatic-hydraulic booster cylinder, comprising a booster cylinder body and a hydraulic oil cup. The hydraulic oil cup includes an oil-containing section and a booster section. The oil-containing section is used to contain hydraulic oil, and the booster section is used to boost the hydraulic oil. The oil-containing section and the booster section are separated from each other, and an oil passage is provided between the oil-containing section and the booster section. A booster space is provided inside the booster cylinder body, and a booster piston rod is provided in the booster space. A pressurization port connected to the booster section is provided in the booster space, and the booster piston rod is located at the pressurization port and connected to the booster section.

[0005] Specifically, the oil-containing part is provided with an oil-containing cavity for containing hydraulic oil, and the pressure-boosting part is provided with a pressure-boosting channel. The oil-containing cavity and the pressure-boosting channel are connected through the oil passage.

[0006] Specifically, the end of the pressurizing unit away from the pressurizing port is provided with a hydraulic output port, which is connected to the pressurizing channel and is used to output pressurized hydraulic oil.

[0007] Specifically, the hydraulic output port includes a connecting section, an output section, and a connecting section arranged sequentially from bottom to top. The connecting section is located inside the pressurizing part, and the diameter of the connecting section is smaller than the diameter of the pressurizing channel. The output end is located inside the pressurizing part, and the diameter of the output section is larger than the diameter of the connecting section. The connecting section is located inside the pressurizing part and extends upward to the outside of the pressurizing part. The diameter of the connecting section is the same as the diameter of the output section, and a connecting thread is provided on the outer side of the connecting section.

[0008] Specifically, the hydraulic oil cup is located at the top of the booster cylinder body, and the booster piston rod includes a first piston block and a second piston block. The first piston block and the second piston block are fixedly connected. The area of ​​the largest surface of the first piston block is greater than the area of ​​the largest surface of the second piston block. The end of the second piston block away from the first piston block is located in the booster channel.

[0009] Specifically, the initial position of the second piston block is located below the oil passage.

[0010] Specifically, the booster cylinder body is provided with a booster port and a depressurization port, both of which are connected to the booster space. The booster port is located on the side closer to the first piston block, and the depressurization port is located on the side farther away from the booster port.

[0011] Specifically, the upper end of the hydraulic oil cup is provided with an oil inlet, which is connected to the oil-containing part.

[0012] This utility model's technical solution adds a hydraulic oil cup to the body of the booster cylinder.

[0019] like Figures 1 to 2 As shown, a pneumatic-hydraulic booster cylinder includes a booster cylinder body 10 and a hydraulic oil cup 20. The hydraulic oil cup 20 includes an oil-containing part and a booster part. The oil-containing part is used to contain hydraulic oil, and the booster part is used to boost the hydraulic oil. The oil-containing part and the booster part are separated from each other. An oil passage 24 is provided between the oil-containing part and the booster part. A booster space 15 is provided inside the booster cylinder body 10. A booster piston rod is provided inside the booster space 15. A pressurization port connected to the booster part is provided inside the booster space 15. The booster piston rod is located at the pressurization port and is connected to the booster part. When pressurizing the equipment, a hydraulic oil cup 20 is added to the body 10 of the pressurizing cylinder. The hydraulic oil is contained in the oil-containing part of the hydraulic oil cup 20, and the hydraulic oil enters the pressurizing part through the oil passage 24. The pressurizing piston rod pressurizes the hydraulic oil, and the pressurized hydraulic oil enters the equipment to achieve pressurization of the equipment. This facilitates complete cooperation with the original equipment and enables rapid pressurization of the equipment. It also facilitates quick connection of the pressurizing cylinder with the original equipment and improves the compatibility between the pressurizing equipment and the original equipment.

[0020] The oil-containing section is provided with an oil-containing cavity 21 for holding hydraulic oil, and the pressure-boosting section is provided with a pressure-boosting channel 22. The oil-containing cavity 21 and the pressure-boosting channel 22 are connected through an oil passage 24. In this embodiment, hydraulic oil is contained in the oil-containing cavity 21 to facilitate the observation of the remaining hydraulic oil level. At the same time, the hydraulic oil in the oil-containing cavity 21 flows into the pressure-boosting channel 22 by gravity through the oil passage 24, thereby achieving the boosted output of the hydraulic oil.

[0021] A hydraulic output port 23 is provided at the end of the pressurizing unit away from the pressurization port. The hydraulic output port 23 is connected to the pressurization channel 22 and is used to output the pressurized hydraulic oil. In this embodiment, a hydraulic output port 23 is provided on the pressurizing unit to facilitate the output of the pressurized hydraulic oil.

[0022] The hydraulic output port 23 includes a connecting section, an output section, and a connecting section arranged sequentially from bottom to top. The connecting section is located inside the pressure boosting section, and its diameter is smaller than that of the pressure boosting channel 22. The output section is located inside the pressure boosting section, and its diameter is larger than that of the connecting section. The connecting section is located inside the pressure boosting section and extends upwards outside the pressure boosting section. Its diameter is the same as that of the output section, and a connecting thread is provided on its outer side. In this embodiment, the connecting thread on the outer side of the connecting section connects to an external pipeline, thereby facilitating the pressurized hydraulic oil to enter the equipment through the hydraulic output port 23. Simultaneously, by setting the diameter of the connecting section to be smaller than that of the pressure boosting channel 22, the pressure of the hydraulic oil is further increased, improving the pressurization effect.

[0023] The hydraulic oil cup 20 is located on the top of the booster cylinder body 10. The booster piston rod includes a first piston block 13 and a second piston block 14. The first piston block 13 and the second piston block 14 are fixedly connected. The area of ​​the largest surface of the first piston block 13 is greater than the area of ​​the largest surface of the second piston block 14. The end of the second piston block 14 away from the first piston block 13 is located in the booster channel 22.

[0024] The initial position of the second piston block 14 is below the oil passage 24. In this embodiment, the hydraulic oil is pressurized by the second piston block entering the pressurization passage 22. At the same time, when the second piston block 14 starts to pressurize, it will move upward and close the oil passage 24. When the second piston block 14 is depressurized and reset, it will move below the oil passage 24 to open the oil passage 24. This process is repeated to replenish the hydraulic oil in the pressurization passage 22.

[0025] The booster cylinder body 10 is provided with a booster port 11 and a depressurization port 12, both of which are connected to the booster space 15. The booster port 11 is located on the side closer to the first piston block 13, and the depressurization port 12 is located on the side farther from the booster port 11. In this embodiment, the booster port 11 is used to inflate the booster space 15 to move the first piston block 13 within the booster space 15, thereby facilitating booster movement via the first piston block 13 and the second piston block 14. In addition, the depressurization port 12 is used to depressurize the booster space 15 to reset the first piston block 13 and the second piston block 14.

[0026] The upper end of the hydraulic oil cup 20 is provided with an oil filling port 25, which is connected to the oil receiving part. In this embodiment, the hydraulic oil cup 20 is provided with an oil filling port 25 so that hydraulic oil can be added to the hydraulic oil cup 20 through the oil filling port 25, which is convenient and quick.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
