Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a water-cooled filling pump hydraulic system. Background Technology

[0002] The water-cooled filling pump hydraulic system innovatively adopts external tap water for heat dissipation. The tap water pressure flows into the hydraulic oil tank, and the heat of the hydraulic oil is removed through a closed high thermal conductivity heat dissipation pipeline and heat sink. The system eliminates the traditional complex heat dissipation layout, gets rid of space constraints, and has no radiator and related pipelines, reducing manufacturing costs. Its simple structure does not occupy the filling pump space, and it does not require an external motor or electric motor drive, reducing energy consumption. Due to fewer parts and a simplified layout, it also reduces the equipment failure points, making it highly efficient and practical.

[0003] The water-cooled filling pump hydraulic system uses external tap water, which flows into the hydraulic oil tank under its own pressure. The tank is equipped with closed heat dissipation pipes or fins with high thermal conductivity. The heat of the hydraulic oil is transferred to the pipes and fins, and the flowing tap water absorbs and carries away the heat, thereby cooling the hydraulic oil. This process does not require additional power and relies solely on the water pressure of the tap water to complete the heat dissipation cycle, simplifying the power transmission links of traditional heat dissipation systems.

[0004] In existing technologies, the installation of pipe connections in some water-cooled filling pump hydraulic systems is quite complex, which leads to low installation efficiency, extended equipment assembly cycles, increased labor costs, and difficulty in ensuring connection accuracy. This can result in poor sealing, causing water leakage or hydraulic oil leakage, which wastes resources and can also affect system operation due to insufficient hydraulic oil. Therefore, a water-cooled filling pump hydraulic system is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-cooled filling pump hydraulic system, which aims to improve the existing technology. The installation of pipe connections in some water-cooled filling pump hydraulic systems is relatively complicated, which leads to low installation efficiency, extended equipment assembly cycle, increased labor costs, and difficulty in ensuring connection accuracy. It is easy to cause poor sealing, resulting in leakage of tap water or hydraulic oil, which wastes resources and affects system operation due to insufficient hydraulic oil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water-cooled filling pump hydraulic system includes an oil tank. A heat exchanger is fixedly connected inside the oil tank. Two pipes are fixedly connected to the outside of the heat exchanger. Multiple clamping blocks are installed on the outside of each of the two pipes. A fixed ring is slidably connected to the outside of each of the clamping blocks. A support is fixedly connected to the outside of the fixed ring. A motor is fixedly connected inside the support. A gear is fixedly connected to the drive end of the motor. A rack ring is rotatably connected inside the support. The outside of the gear is meshed with the outside of the rack ring. Multiple support columns are fixedly connected to the top of the rack ring. A rotating ring is fixedly connected to the top of the multiple support columns. Multiple connecting rods are slidably connected inside the rotating ring. As a further description of the above technical solution: A protective cover is fixedly connected to the bottom end of the support, and a connecting pipe is fixedly connected to the inner side of the support. As a further description of the above technical solution: The rotating ring has multiple grooves inside, and the outer side of the connecting rod is slidably connected to the inside of the grooves; As a further description of the above technical solution: The top end of the connecting rod is fixedly connected to the bottom end of the clamping block, and the top end of the connecting pipe is in contact with the bottom end of the pipe. As a further description of the above technical solution: The outer side of the motor is in contact with the inside of the protective cover, and the tops of the multiple clamping blocks are slidably connected to the inside of the support; As a further description of the above technical solution: Two limiting rings are fixedly connected to the outer side of each of the multiple connecting rods, and the adjacent sides of the limiting rings are slidably connected to the outer side of the rotating ring.

[0007] This utility model has the following beneficial effects: This invention uses a motor-driven gear to rotate a rack ring, which transmits motion through a support column and a rotating ring. This causes a connecting rod to push a clamping block to contract or expand in a directional manner, enabling rapid assembly and disassembly of pipelines. This structure requires no complex tools, is easy to maintain, reduces downtime, lowers labor intensity, and ensures reliable sealing at the connection points, preventing energy consumption, water loss, and equipment corrosion caused by leaks. At the same time, it facilitates pipeline cleaning, maintains efficient hot and cold water circulation, ensures stable hydraulic oil temperature, and improves system reliability.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a water-cooled filling pump hydraulic system, including an oil tank 1. The oil tank 1 provides a mounting base for other components, such as a fixedly connected heat exchanger 2, ensuring the normal circulation and supply of hydraulic fluid to the system. The heat exchanger 2 is fixedly connected inside the oil tank 1. The heat exchanger 2 absorbs heat from inside the oil tank 1, and the absorbed heat is carried away by water flowing through pipes 3. Two pipes 3 are fixedly connected to the outside of the heat exchanger 2. The pipes 3 are channels for cooling water flow. Cooling water flows in from one side of the pipe 3, passes through the heat exchanger 2, carries away the heat, and becomes hot water, flowing out from the other side of the pipe 3.

[0012] Multiple clamping blocks 4 are installed on the outer sides of both pipes 3. The clamping blocks 4 are mainly used to fix and clamp the pipes 3 and connect them to the connecting pipe 14. A fixing ring 5 is slidably connected to the outer side of each clamping block 4. The fixing ring 5 guides and limits the movement of the clamping block 4, allowing it to slide stably on its outer side and ensuring that the clamping block 4 moves along a predetermined trajectory during operation. A support 6 is fixedly connected to the outer side of the fixing ring 5. The support 6 provides an installation and support platform for other components of the entire connection assembly, integrating components such as the motor 7 and rack ring 10, ensuring the relative position stability between the components and facilitating collaborative work.

[0013] A motor 7 is fixedly connected inside the support 6. The motor 7 is the power source for the connecting components. It drives the gear 9 to rotate through its drive end, providing power for a series of subsequent mechanical movements. The drive end of the motor 7 is fixedly connected to the gear 9. The gear 9 rotates under the drive of the motor 7, and through meshing with the rack ring 10, it converts the rotational motion of the motor 7 into the rotation of the rack ring 10. The rack ring 10 is rotatably connected inside the support 6. The outer side of the gear 9 is meshed with the outer side of the rack ring 10. The rack ring 10 rotates under the drive of the gear 9, which in turn drives the rotating ring 12 to rotate through the support column 11, thus transmitting motion and power.

[0014] Multiple support columns 11 are fixedly connected to the top of the rack ring 10. The support columns 11 connect the rack ring 10 and the rotating ring 12, transmitting the rotation of the rack ring 10 to the rotating ring 12, serving as an intermediate connecting component for motion transmission. The rotating ring 12 is fixedly connected to the top of the multiple support columns 11. Driven by the rack ring 10 and the support columns 11, the rotating ring 12 rotates, driving the connecting rod 13 through its internal groove, thus acting as an intermediate transmission mechanism. Multiple connecting rods 13 are slidably connected inside the rotating ring 12. One end of each connecting rod 13 is connected to the clamping block 4, and the other end slides within the groove of the rotating ring 12, converting the rotation of the rotating ring 12 into the sliding of the clamping block 4, thereby achieving the clamping or releasing action of the clamping block 4 on the pipe 3.

[0015] Reference Figures 2 to 4 A protective cover 8 is fixedly connected to the bottom end of the support 6. The protective cover 8 is fitted over the outside of the motor 7, protecting the motor 7 and preventing external dust, impurities, etc. from entering the motor 7 and affecting its normal operation. It also prevents personnel from accidentally touching the rotating parts of the motor 7 and causing safety hazards. A connecting pipe 14 is fixedly connected to the inside of the support 6. The connecting pipe 14 connects the support 6 and the pipe 3 and serves as a channel for the flow of cooling water, ensuring that cooling water can smoothly enter or flow out of the oil tank 1 area. The rotating ring 12 has multiple grooves inside. The outer side of the connecting rod 13 is slidably connected to the inside of the grooves. The grooves provide guidance for the connecting rod 13, allowing it to slide along a fixed track and preventing the movement of the connecting rod 13 from deviating.

[0016] The top end of connecting rod 13 is fixedly connected to the bottom end of clamping block 4. The movement of connecting rod 13 drives the movement of clamping block 4, enabling clamping block 4 to fix and disassemble pipe 3. The top end of connecting pipe 14 contacts the bottom end of pipe 3. The outer side of motor 7 contacts the inside of protective cover 8, and the top ends of multiple clamping blocks 4 are slidably connected to the inside of support 6. Two limiting rings are fixedly connected to the outer side of multiple connecting rods 13. The adjacent side of the limiting rings is slidably connected to the outer side of rotating ring 12. The limiting rings limit the sliding of connecting rod 13 on rotating ring 12, preventing connecting rod 13 from disengaging from the groove of rotating ring 12 and ensuring the stability of the movement of connecting rod 13.

[0017] Working principle: When motor 7 is started, it rotates and drives gear 9, which is fixedly connected to its drive end, to rotate. The rotation of gear 9 causes rack ring 10, which meshes with it, to rotate inside support 6. Rack ring 10 transmits its motion to support column 11, and the movement of support column 11 drives rotating ring 12 to rotate. The movement of rotating ring 12 causes connecting rod 13 to slide within its internal groove, causing connecting rod 13 to drive clamping block 4 to move along the fixed direction of the groove. While moving, clamping block 4 is restricted by fixed ring 5, causing multiple clamping blocks 4 to move in a fixed direction, contracting inward or expanding outward, thus achieving the connection and disconnection of pipe 3 and connecting pipe 14 quickly. The disassembly and assembly of pipe 3 and connecting pipe 14 can be completed quickly without the need for complicated tools during routine maintenance or troubleshooting. This not only significantly shortens the working time of pipeline maintenance and reduces the labor intensity of maintenance personnel, but also reduces production delays caused by equipment downtime. At the same time, it can enhance the reliability of the connection, reduce energy loss and water waste caused by hot and cold water leakage, and avoid problems such as equipment dampness and corrosion caused by water leakage. In addition, the convenient disassembly and assembly features also facilitate the regular cleaning of scale and impurities inside the pipeline, which helps to maintain the pipeline unobstructed, ensures stable hot and cold water circulation efficiency, avoids the decrease in cooling effect caused by pipeline blockage, and thus ensures that the hydraulic oil is always within the appropriate temperature range.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
