Description

Technical Field

[0001] This utility model relates to the field of hydraulic transmission equipment technology, specifically to a hydraulic transmission device. Background Technology

[0002] Hydraulic transmission equipment typically consists of a hydraulic pump, hydraulic cylinders, control valves, and auxiliary equipment. The hydraulic pump, as a power source, converts mechanical energy into hydraulic energy, pressurizing the fluid. This pressure energy is then transmitted via hydraulic oil to the actuators, such as the hydraulic cylinder or hydraulic motor, generating corresponding force and motion. During this process, the control valve regulates the flow rate, pressure, and direction of the fluid to meet the system's operational requirements. Auxiliary equipment, such as oil tanks and filters, ensures the normal operation of the system.

[0003] In hydraulic transmission equipment, the purity and stability of hydraulic oil are crucial for the normal operation of the equipment. However, traditional hydraulic transmission equipment often lacks an effective filtration mechanism when adding hydraulic oil, which makes it easy for impurities to enter the oil tank, affecting the purity of the hydraulic oil and thus reducing the operating efficiency and stability of the equipment. At the same time, after prolonged use of hydraulic oil, wear particles will be generated inside the oil tank. If these particles enter the hydraulic pump, they will cause serious damage to the hydraulic pump and shorten the service life of the equipment. Therefore, this utility model provides a hydraulic transmission device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic transmission device that solves the problem that traditional hydraulic transmission devices often lack an effective filtration mechanism when adding hydraulic oil, which allows impurities to easily enter the oil tank, affecting the purity of the hydraulic oil and thus reducing the operating efficiency and stability of the equipment. At the same time, after prolonged use of hydraulic oil, wear particles will be generated inside the oil tank. If these particles enter the hydraulic pump, they will cause serious damage to the hydraulic pump and shorten the service life of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic transmission device, including a mounting base, a hydraulic transmission body fixed to the upper end of the mounting base, an oil tank fixed to the rear side of the hydraulic transmission body, a conduit connected to one side of the oil tank, a hydraulic pump connected to one end of the conduit, a hydraulic cylinder connected to one side of the hydraulic pump, and a hydraulic mechanism for the hydraulic transmission device provided on the mounting base, the hydraulic mechanism including:

[0013] This utility model provides a hydraulic transmission device. Compared with the prior art, it has the following advantages:

[0014] Firstly, the oil inlet of this invention is used to add liquid to the oil tank. The added liquid is then filtered through the second filter inside the sealed cylinder to prevent impurities from entering the oil tank and ensure the purity of the hydraulic oil. When the hydraulic pump draws hydraulic oil from the oil tank through the conduit, the first filter inside the sealing block filters impurities in the pipeline, preventing wear particles generated during long-term operation of the oil tank from entering the hydraulic pump. Furthermore, during disassembly, the first bolt on the mounting plate at the upper end of the sealing block is loosened, and the sealing block is pulled out along the inside of the mounting base. Simultaneously, the second filter on the sealing cylinder, connected to the side wall of the mounting plate via the connecting bracket, is separated from the oil inlet, allowing for simultaneous disassembly of the first and second filters. This simplifies the cleaning and replacement process of the filters, improves the maintainability of the equipment, and reduces equipment failures caused by filter clogging or contamination.

[0015] Secondly, the push block of this utility model is raised and lowered by the first electric push rod, and then the slider bracket is rotatably connected to the push block through the rotating shafts at both ends of the movable rod. When the movable rod changes angle, the locking ring opens and closes inside the slide rail bracket through the slider bracket, thereby locking the telescopic hydraulic rod and ensuring the stability of the hydraulic rod after telescopic movement. This avoids operational errors or equipment damage caused by shaking or instability. At the same time, a rubber ring is fixed on the inner wall of the locking ring to increase the friction with the outer wall of the hydraulic rod and reduce the wear caused to it.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a hydraulic transmission device, including a mounting base 1, a hydraulic transmission body 2 fixed to the upper end of the mounting base 1, an oil tank 3 fixed to the rear side of the hydraulic transmission body 2, a conduit 301 connected to one side of the oil tank 3, a hydraulic pump 302 connected to one end of the conduit 301, and a hydraulic cylinder 7 connected to one side of the hydraulic pump 302. When the hydraulic transmission device needs to work, the hydraulic pump 302 is first started. The hydraulic pump 302 draws hydraulic oil from the oil tank 3 through the conduit 301. The drawn hydraulic oil is pressurized by the hydraulic pump 302 and continues to flow through the conduit 301 or other internal conduits. The hydraulic oil flows through the pipeline to the hydraulic cylinder 7. The pressurized hydraulic oil enters the internal chamber of the hydraulic cylinder 7. The output end of the hydraulic cylinder 7 is connected to the hydraulic rod 701. The hydraulic rod 701 extends or retracts with the movement of the hydraulic cylinder 7. Through its extension or retraction, the hydraulic rod 701 pushes or pulls the connected load to complete the predetermined work task. After the hydraulic cylinder 7 completes its operation, the internal hydraulic oil flows back to the oil tank 3 through the corresponding return pipeline. The oil tank 3 receives the returned hydraulic oil and stores it for future use. The mounting base 1 is equipped with a hydraulic mechanism for the hydraulic transmission equipment. The hydraulic mechanism includes:

[0023] The filter assembly includes a mounting base 4 that is internally connected to the conduit 301, a sealing block 401 that is slidably connected inside the mounting base 4, a first filter screen 402 that is fixed inside the sealing block 401, an oil inlet 503 that is provided at the upper end of the oil tank 3, a sealing cylinder 501 that is engaged inside the oil inlet 503, and a second filter screen 502 that is fixed on the inner wall of the sealing cylinder 501.

[0024] The locking assembly includes a support frame 8 fixed to the upper surface of the mounting base 1, a slide rail bracket 801 fixed to the upper end of the support frame 8, a slider bracket 802 connected by a push assembly inside the slide rail bracket 801, and a locking ring 803 fixed to the inner wall of the slider bracket 802.

[0025] In a preferred embodiment, a mounting plate 403 is fixed to the upper end face of the sealing block 401. First bolts 404 are installed inside the four ends of the mounting plate 403. A connecting bracket 5 is fixed to the side wall of the mounting plate 403. A fixing rod 6, rotatably connected via a rotating shaft, is installed on the upper end face of the connecting bracket 5. A sealing cover 601 is fixed to the lower end face of the fixing rod 6. A second bolt 602 is installed inside the fixing rod 6. An oil inlet 503 is provided for adding liquid to the oil tank 3. The added liquid is then filtered through a second filter 502 inside the sealing cylinder 501 to prevent impurities from entering the oil tank 3, ensuring the purity of the hydraulic oil. When the hydraulic pump 302 draws hydraulic oil from the oil tank 3 through the conduit 301, the first filter 402 inside the sealing block 401 is used to remove impurities from the pipeline. The filter performs filtration to prevent wear particles generated during long-term operation of the oil tank 3 from entering the interior of the hydraulic pump 302. When disassembling, the first bolt 404 of the mounting plate 403 at the upper end of the sealing block 401 is loosened, and the sealing block 401 is pulled out along the interior of the mounting base 4. At the same time, the second filter screen 502 on the sealing cylinder 501 connected by the connecting bracket 5 to the side wall of the mounting plate 403 is separated from the oil inlet 503, realizing the simultaneous disassembly of the first filter screen 402 and the second filter screen 502. This simplifies the cleaning and replacement process of the filter screen, improves the maintainability of the equipment, and reduces equipment failures caused by filter screen blockage or contamination. The sealing cover 601 is opened and closed with the sealing cylinder 501 through the fixing rod 6 and the second bolt 602 for the closure of the sealing cylinder 501.

[0026] In a preferred embodiment, the pushing assembly includes a first electric push rod 804 fixed to the upper surface of the mounting base 1. A push block 805 is fixed to the telescopic end of the first electric push rod 804. A slider bracket 802 is located inside the slide rail bracket 801. Movable rods 806 are rotatably connected to both sides of the push block 805 via a rotating shaft. The other end of the movable rod 806 is rotatably connected to the bottom of the slider bracket 802 via a rotating shaft. Two sets of locking rings 803 are provided, and rubber rings for increasing friction are fixed to the inner wall of the locking rings 803. A hydraulic rod 701 is connected to the output end of the hydraulic cylinder 7. 805 is raised and lowered by the first electric push rod 804. Then, the slider bracket 802 is rotatably connected to the push block 805 through the rotating shafts at both ends of the movable rod 806. When the movable rod 806 changes angle, the locking ring 803 opens and closes inside the slide rail bracket 801 through the slider bracket 802, thereby locking the telescopic hydraulic rod 701 to ensure the stability of the hydraulic rod 701 after telescopic movement. This avoids operational errors or equipment damage caused by shaking or instability. At the same time, a rubber ring is fixed to the inner wall of the locking ring 803 to increase the friction with the outer wall of the hydraulic rod 701 and reduce the wear caused to it.

[0027] In a preferred embodiment, a second electric push rod 9 is fixed to the upper end face of the mounting base 1. A concave frame 901 is fixed to the telescopic end of the second electric push rod 9. A support roller 902 is rotatably connected inside the concave frame 901. When the hydraulic rod 701 is telescopic, it is supported by the support roller 902, which disperses the pressure borne by the hydraulic rod 701 and improves the overall load-bearing capacity.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] When the hydraulic transmission equipment needs to work, the hydraulic pump 302 is started first. The hydraulic pump 302 draws hydraulic oil from the oil tank 3 through the conduit 301. After being pressurized by the hydraulic pump 302, the hydraulic oil continues to flow to the hydraulic cylinder 7 through the conduit 301 or other internal pipes. The pressurized hydraulic oil enters the internal chamber of the hydraulic cylinder 7. The output end of the hydraulic cylinder 7 is connected to the hydraulic rod 701. The hydraulic rod 701 extends or retracts with the movement of the hydraulic cylinder 7. The hydraulic rod 701 pushes or pulls the load connected to it by extending or retracting, thus completing the predetermined work task. After the hydraulic cylinder 7 completes its action, the internal hydraulic oil will flow back to the oil tank 3 through the corresponding return pipe. The oil tank 3 receives the returned hydraulic oil and stores it for the next use.

[0030] Then, the oil inlet 503 is used to add liquid to the oil tank 3. The added liquid is then filtered through the second filter 502 inside the sealing cylinder 501 to prevent impurities from entering the oil tank 3 and to ensure the purity of the hydraulic oil. When the hydraulic pump 302 draws hydraulic oil from the oil tank 3 through the conduit 301, the first filter 402 inside the sealing block 401 is used to filter impurities in the pipeline to prevent wear particles generated during long-term operation of the oil tank 3 from entering the hydraulic pump 302. When disassembling, the first bolt 404 of the mounting plate 403 at the upper end of the sealing block 401 is loosened, and the sealing block 401 is pulled out along the inside of the mounting base 4. At the same time, the installation... The second filter screen 502 on the sealing cylinder 501 connected to the side wall of plate 403 via the connecting bracket 5 is separated from the oil inlet 503, enabling the simultaneous disassembly of the first filter screen 402 and the second filter screen 502. The push block 805 is raised and lowered via the first electric push rod 804. Then, the slider bracket 802 is rotatably connected to the push block 805 via the rotating shafts at both ends of the movable rod 806. When the movable rod 806 changes angle, the locking ring 803 opens and closes inside the slide rail bracket 801 via the slider bracket 802, thereby locking the telescopic hydraulic rod 701 and ensuring the stability of the hydraulic rod 701 after telescopic movement, thus avoiding operational errors or equipment damage caused by shaking or instability.
