[0025] 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.
[0026] Please see Figures 1-5 A hydraulic automatic tilting platform includes a base 1, an L-shaped tilting plate 2 installed at the upper middle of the base 1, a mounting seat 4 fixedly installed on one side bottom of the base 1, a hydraulic cylinder 5 installed on the inner side of the mounting seat 4, a liquid chamber 7 opened inside the hydraulic cylinder 5, an oil inlet pipe 12 and an oil outlet pipe 13 fixedly installed at the upper and lower ends of the hydraulic cylinder 5 respectively, and inlet and outlet hoses 14 installed on the outer sides of the oil inlet pipe 12 and the oil outlet pipe 13 respectively. An oil injection device is connected to the other side of the inlet and outlet hoses 14. By setting the oil inlet pipe 12 and the oil outlet pipe 13 at the upper and lower ends of the hydraulic cylinder 5, and installing the inlet and outlet hoses 14 of the oil injection device on their outer sides, when the oil injection device is working, hydraulic oil can be injected into the hydraulic cylinder 5 through the oil inlet pipe 12, which pushes the piston to move and realize the platform tilting. Hydraulic oil can also be discharged through the oil outlet pipe 13 to control the platform to reset, ensuring the normal cycle operation of the hydraulic automatic tilting platform.
[0027] Two arc-shaped mounting plates 15 are provided on the outside of the oil inlet pipe 12 and the oil outlet pipe 13. Hinges 16 are installed on the sides of the two arc-shaped mounting plates 15. During installation, the arc-shaped mounting plates 15 are rotated around the hinges 16 to close them. This makes the connection between the pipeline and the hydraulic cylinder 5 convenient and allows for quick positioning of the installation position. After closing, the arc-shaped mounting plates 15 can form a protective enclosure at the connection between the pipeline and the hydraulic cylinder 5, enhancing the overall structural stability. Grooves 17 are provided on the corresponding surfaces of the oil inlet pipe 12, the oil outlet pipe 13, and the inlet / outlet hose 14. Sealing rings 18 are installed on the inner side of the grooves 17. When the hydraulic system is working, the sealing rings 18 are compressed and deformed, tightly filling the gaps between the pipelines, effectively preventing hydraulic oil leakage, maintaining stable system pressure, and ensuring that the L-shaped flip plate 2 flips smoothly and accurately. Rings are provided on the corresponding surfaces of the oil inlet pipe 12, the oil outlet pipe 13, and the inlet / outlet hose 14. The inner surfaces of the two arc-shaped mounting plates 15 are fixedly installed with multiple arc-shaped sealing blocks 20. By setting up the arc-shaped mounting plates 15 with hinges 16, the sealing rings 18 in the grooves 17, the annular grooves 19, and the arc-shaped sealing blocks 20, during installation, the two arc-shaped mounting plates 15 are closed around the oil inlet pipe 12, the oil outlet pipe 13, and the inlet and outlet hydraulic hoses 14, so that the arc-shaped sealing blocks 20 are embedded in the annular grooves 19. The sealing rings 18 in the grooves 17 are tightly attached to the surface of the pipeline, forming a multi-layer sealing structure. When hydraulic oil flows between the pipeline and the hydraulic cylinder 5, the sealing rings 18 and the arc-shaped sealing blocks 20 can effectively prevent hydraulic oil leakage, greatly improve the sealing performance of the connection, reduce the problem of unstable hydraulic system pressure caused by hydraulic oil leakage, improve production efficiency, and avoid resource waste, environmental pollution, and product quality problems caused by leakage.
[0028] Please see Figures 2-5 When the two arc-shaped mounting plates 15 are closed, multiple arc-shaped sealing blocks 20 are respectively connected to the inner side of the annular groove 19. Semi-circular screws 21 are fixedly installed on the side of the two arc-shaped mounting plates 15 away from the hinge 16 to prevent hydraulic oil from leaking from the connection between the pipeline and the hydraulic cylinder 5 and to ensure stable system pressure.
[0029] Two arc-shaped mounting plates 15 are equipped with handwheels 22 on the outer side near the semi-circular screws 21. A screw hole 23 is provided on the inner side of the handwheel 22. When the two semi-circular screws 21 are close together, they are threaded into the screw hole 23. By setting up the handwheel 22, semi-circular screws 21, and screw hole 23, when it is necessary to tighten the connection between the pipeline and the hydraulic cylinder 5, rotating the handwheel 22 will cause it to advance along the threads of the two semi-circular screws 21, pushing the two arc-shaped mounting plates 15 closer together, making the arc-shaped sealing block 20 more tightly embedded in the annular groove 19, enhancing the sealing effect. When disassembly is required, rotating the handwheel 22 in the opposite direction will cause it to retract along the threads of the semi-circular screws 21, separating the two arc-shaped mounting plates 15. This eliminates the need for complex tools; operators can easily complete the installation and disassembly operations simply by rotating the handwheel 22. The operation process is greatly simplified, saving a significant amount of time and manpower. It allows for rapid disassembly of pipeline connections, effectively shortening equipment downtime, reducing enterprise maintenance costs, and minimizing production losses.
[0030] Two hinge seats 3 are fixedly installed at both ends of the middle of the base 1. The bending part of the L-shaped flip plate 2 is hinged to the inner side of the two hinge seats 3, providing a stable rotation fulcrum for the L-shaped flip plate 2. When the hydraulic cylinder 5 is driven, the L-shaped flip plate 2 can flexibly flip around the hinge seats 3, ensuring smooth and stable flipping action, improving the stability and accuracy of the platform flipping, and meeting actual working requirements. A piston rod 8 is provided inside the hydraulic cavity 7. A piston plate 9 is fixedly installed at the bottom of the piston rod 8 and fits against the inner wall of the hydraulic cavity 7. A support rod 6 is fixedly installed on the upper end of one side of the L-shaped flip plate 2. The upper end of the piston rod 8 passes through the hydraulic cylinder 5 and is hinged to the surface of the support rod 6, effectively using the pressure of hydraulic oil to drive the piston plate 9 to move. At the same time, the upper end of the piston rod 8 is hinged to the L-shaped flip plate 2. On the surface of the support rod 6 at the upper end of one side of plate 2, when the piston plate 9 drives the piston rod 8 to make linear motion under hydraulic action, the piston rod 8 can convert the linear motion into the L-shaped flipping plate 2 flipping motion around the hinge seat 3 through the support rod 6, so as to realize the stable flipping of the platform and make the entire hydraulic automatic flipping platform work normally. A sealing ring 10 is fixedly installed on the side of the piston plate 9 near the piston rod 8. A sealing groove 11 is opened on the surface of the liquid chamber 7 near the output end of the hydraulic cylinder 5. When the piston plate 9 is in contact with the inner wall of the liquid chamber 7 near the output end of the hydraulic cylinder 5, the sealing ring 10 is connected to the inside of the sealing groove 11. When the piston plate 9 approaches the output end of the hydraulic cylinder 5 and is in contact with the inner wall, the sealing ring 10 is embedded in the sealing groove 11, effectively preventing hydraulic oil leakage and ensuring the stability of the pressure in the liquid chamber 7.
[0031] Working principle: In actual use, first connect the external oil injection device to the inlet and outlet hoses 14 correctly to ensure that the oil can flow smoothly in the system. Turn on the oil injection device, and the oil is injected into the hydraulic chamber 7 of the hydraulic cylinder 5 through the oil inlet pipe 12 and the inlet and outlet hoses 14. As the amount of oil in the hydraulic chamber 7 increases, the pressure gradually increases.
[0032] When the pressure reaches a certain level, the piston plate 9 begins to move towards the output end of the hydraulic cylinder 5 under the pressure. As the piston plate 9 approaches the output end of the hydraulic cylinder 5, the sealing ring 10 on the piston plate 9 gradually embeds into the sealing groove 11 on the side of the liquid chamber 7 near the output end. The two work closely together to form an effective seal at the connection between the piston rod 8 and the hydraulic cylinder 5, preventing hydraulic oil from leaking from here and ensuring that the pressure acts stably on the piston plate 9, pushing the piston plate 9 to drive the piston rod 8 to move upward continuously. Since the upper end of the piston rod 8 is hinged to the support rod 6 on one side of the L-shaped flip plate 2, the rise of the piston rod 8 will drive the support rod 6, thereby driving the L-shaped flip plate 2 to flip around the hinge seats 3 at both ends of the middle part of the base 1, completing the flipping operation of the platform.
[0033] When it is necessary to return the L-shaped flip plate 2 to its initial position or adjust the flip angle, the oil injection device is controlled to make the oil flow from the oil outlet pipe 13 and the inlet and outlet hoses 14 out of the liquid chamber 7. The amount of oil in the liquid chamber 7 decreases, the pressure decreases, and the piston plate 9 and piston rod 8 begin to move downward until the piston plate 9 returns to its initial position, waiting for the next flip command.
[0034] The arc-shaped mounting plate 15, connected by the hinge 16, closes around the oil inlet pipe 12, oil outlet pipe 13, and inlet / outlet fluid hose 14. The arc-shaped sealing block 20 on the inner surface of the arc-shaped mounting plate 15 is embedded in the annular groove 19 on the corresponding pipe surface. The sealing ring 18 in the groove 17 on the corresponding pipe surface fits tightly, forming a multi-layer seal. To install, disassemble, or maintain the pipe and hydraulic cylinder 5, rotate the handwheel 22 in the opposite direction. The handwheel 22 disengages from the two semi-circular screws 21, causing the two arc-shaped mounting plates 15 to separate, making it easy to disassemble the pipe and hydraulic cylinder 5 for subsequent operations.
