[0025] Embodiment

[0026] As Figures 1-4As shown in the figure, a pneumatic hydraulic pump proposed in an embodiment of the present utility model includes a pump housing 1. One side of the pump body 1 is buckled on a mounting plate 2. An oil inlet and outlet 4 is threadedly embedded in the pump housing 1. A fixing column 5 is inserted into the mounting plate 2. One end of the fixing column 5 is fixedly connected to a side plate 6. A pneumatic motor 7 is fixedly installed on the side plate 6. The output end of the pneumatic motor 7 is fixedly connected to a rotating shaft 8. One end of the rotating shaft 8 is fixedly connected to a driving gear disk 9. The driving gear disk 9 meshes and drives a driven gear disk 10. The pump housing 1 is provided with heat dissipation fins 11. The bottom of the pump housing 1 is fixedly installed with a base 12. A silent cover 13 is fixedly installed on the base 12;

[0027] Pump housing 1: As the main body housing of the pump, it provides protection and support. The pump housing 1 ensures the safety of internal components while maintaining the overall shape and structural stability of the pump;

[0028] Mounting plate 2: It is buckled with the pump housing and provides a mounting base for other components.

[0029] Screw 3: It is distributed at the four corners of the pump housing 1 to strengthen the firm connection between the pump housing 1 and the mounting plate 2; Through the buckling of the mounting plate 2 with the pump housing 1 and the fixation of the screw 3, the accurate installation position and firmness of each component are guaranteed; The screw 3 effectively prevents the pump from loosening or displacing during operation;

[0030] Oil inlet and outlet 4: It has an internal thread design, which is convenient for connecting with oil pipes, etc., and precisely controls the inflow and outflow of oil; The oil inlet and outlet 4 precisely controls the inflow and outflow of oil to ensure the normal operation of the hydraulic system;

[0031] Fixing column 5: It is vertically inserted into the mounting plate 2 to provide stable support for the side plate 6.

[0032] Side plate 6: It connects the fixing column 5 and the pneumatic motor 7, playing a role of transition and fixation.

[0033] Pneumatic motor 7: As the power source, it converts the energy of compressed air into mechanical energy; The fixing column 5 ensures the stability of the installation of the side plate 6 and the pneumatic motor 7, and bears the vibration and stress during operation;

[0034] Rotating shaft 8: It transmits the power of the pneumatic motor 7.

[0035] Driving gear disk 9: It is connected to the rotating shaft 8 and transmits power through rotation; The rotating shaft 8 efficiently transmits the rotational power of the pneumatic motor 7 to the driving gear disk 9;

[0036] Driven gear disk 10: It meshes with the driving gear disk 9 to achieve power transmission and conversion; The driving gear disk 9 changes the power direction and speed through meshing and driving with the driven gear disk 10;

[0037] Heat dissipation fins 11: They are evenly distributed on the pump housing 1 in a specific shape, increasing the heat dissipation area; the heat dissipation fins 11 accelerate heat dissipation and prevent the pump from being damaged or its performance from degrading due to overheating;

[0038] Base 12: It is located at the bottom of the pump housing 1, providing a stable support and an installation plane.

[0039] Silent cover 13: It covers the entire device and is made of fiberglass; the silent cover 13 effectively blocks and absorbs noise, reducing the impact of the noise generated during the operation of the pump on the outside world. At the same time, the fiberglass material has a certain strength and durability;

[0040] When the pneumatic motor 7 is started, its output end drives the rotating shaft 8 to rotate, and then the drive gear disk 9 connected to the rotating shaft 8 rotates. The drive gear disk 9 transmits power to the driven gear disk 10 through meshing transmission with the driven gear disk 10. As the drive gear disk 9 and the driven gear disk 10 rotate, they will drive related components to move inside the pump housing 1.

[0041] In this process, when the space inside the pump housing 1 changes, a pressure difference will be generated at the oil inlet and outlet 4. When the pressure is low, the liquid is sucked into the pump housing 1 from the outside through the internal thread structure of the oil inlet and outlet 4; when the pressure rises, the liquid will be squeezed out from the oil inlet and outlet 4, realizing the suction and discharge of the oil, thus completing the hydraulic transmission process.

[0042] At the same time, the heat dissipation fins 11 use their large surface area to quickly dissipate the heat generated during the operation of the pump, preventing the pump from malfunctioning or its performance from degrading due to overheating.

[0043] When the entire device is operating, the silent cover 13 will effectively block and absorb the noise generated during operation, reducing the noise impact on the outside world. The silent cover 13 made of fiberglass not only has good sound insulation effect but also has a certain strength and durability, and can stably cover and protect the entire device. The fixing posts 5 ensure the stability of the installation of the side plate 6 and the pneumatic motor 7, and the screw 3 further strengthens the firmness of the connection between the pump housing 1 and the mounting plate 2, ensuring the stability and reliability of the entire device during operation.

[0044] As Figure 2 shown, in some embodiments, screws 3 thread through the four corners of the pump housing 1, and the screws 3 are threadedly connected to a location inside the mounting plate 2, enhancing the stability of the connection between the pump housing 1 and the mounting plate 2. Through the fixation of multiple screws 3, it can effectively prevent the pump housing 1 from shaking, shifting, etc. during the working process, ensuring the stability of the operation of the entire device.

[0045] As Figure 4As shown, in some embodiments, the driving gear disk 9 and the driven gear disk 10 are rotatably arranged inside the pump housing 1. The driving gear disk 9 rotates driven by the rotating shaft 8, and its rotation drives the driven gear disk 10 engaged with it to rotate accordingly. This meshing transmission method can effectively transfer the power from the driving gear disk 9 to the driven gear disk 10.

[0046] As Figure 1 shown, in some embodiments, the inside of the soundproof cover 13 covers all the structures, and there are reserved holes on the surface. Covering all the structures inside can wrap the whole device to the greatest extent, so that the noise generated during the operation of the pump can be blocked from spreading to the outside in all directions, effectively reducing the noise pollution. At the same time, the reserved holes on the surface are for meeting some necessary functional requirements. These reserved holes may be used for some components to extend out and connect to the outside. For example, the oil inlet / outlet 4 may need to be connected to the external oil pipe through the reserved hole, or for the cables of some sensors to pass through to realize functions such as monitoring.

[0047] As Figure 1 shown, in some embodiments, the soundproof cover 13 is fixedly connected to the base 12 by bolts. The bolt connection provides reliable fastening force to ensure that the soundproof cover 13 can be firmly installed on the base 12. During the operation of the equipment, it will not easily loosen or shift due to factors such as vibration, ensuring the continuity and stability of the soundproof effect.

[0048] As Figure 1 shown, in some embodiments, the soundproof cover 13 is a fiberglass cover plate. Fiberglass has good sound insulation performance, which can effectively block the spread of sound and further enhance the soundproof effect. At the same time, it also has certain strength and durability, and can better protect the internal structure. The fiberglass material is relatively light and will not bring too much extra weight to the whole device.

[0049] As Figure 4 shown, in some embodiments, the heat dissipation fins 11 are evenly distributed, and the heat dissipation fins 11 and the pump housing 1 are of an integrally formed structure. When the heat dissipation fins 11 are evenly distributed, this brings many benefits. The even distribution ensures the uniformity of heat dissipation, and there will be no local overheating or overcooling. The heat of the whole pump housing 1 can be dissipated more evenly. The integrally formed structure is relatively convenient in manufacturing, can be formed in one step, reducing the production cost and manufacturing difficulty.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
