[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. Hydraulic cylinders have a simple structure, high working efficiency, and smooth operation when used to achieve reciprocating motion. Hydraulic technology originated during the Industrial Revolution, and early hydraulic cylinders were mainly used for simple mechanical transmission and pressure transmission.

[0003] During rescue operations, the equipment needs to be moved frequently, and due to the complex rescue environment, the movement is difficult. This requires hydraulic cylinders that can withstand extremely high loads. At the same time, in order to be easy to carry, the weight of the hydraulic cylinders must be light to adapt to the existing working environment.

[0004] Most existing hydraulic cylinders are alloy steel hydraulic cylinders such as aluminum alloy hydraulic cylinders and titanium alloy hydraulic cylinders. Although some adopt lightweight design, their structural design is unreasonable, which affects the overall strength of the hydraulic cylinder. Therefore, a double-acting ultra-high pressure carbon composite hydraulic cylinder is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a double-acting ultra-high pressure carbon composite hydraulic cylinder, including a cylinder barrel 1. The cylinder barrel 1 is the outermost cylinder body of the hydraulic rod and also the main support. It is made of high-strength aluminum alloy and is used to accommodate piston rods. Piston rod 1 2 is slidably connected inside the cylinder barrel 1. Piston rod 2 3 is slidably connected inside the piston rod 1 2. Piston rod 3 4 is slidably connected inside the piston rod 2 3. Each piston rod can extend and retract to achieve multi-level height adjustment and increase the lifting height of the hydraulic rod. Oil injection pipe 1 5 and oil injection pipe 2 6 are fixedly connected to the outside of the cylinder barrel 1. When hydraulic oil is injected into the cylinder barrel 1 from oil injection pipe 1 5, it first pushes piston rod 1 2 outward, and then gradually pushes piston rod 2 3 and piston rod 3 4 out in sequence to lift objects. When hydraulic oil is injected into the cylinder barrel 1 from oil injection pipe 2 6, it first pushes piston rod 3 4 back, retracting piston rod 3 4 into piston rod 2 3. Then piston rod 2 3 and piston rod 1 2 are retracted in sequence. A reinforcing component is provided on the outside of the cylinder barrel 1, and a sealing component is provided inside the cylinder barrel 1.

[0035] The reinforcing component includes a reinforcing layer 11, which is fixedly connected to the outside of the cylinder 1. When installing the reinforcing layer 11, a corresponding groove needs to be made on the outside of the cylinder 1, and then carbon fiber material is wound into the groove. Different winding methods are used at different positions to increase the strength of the hydraulic rod. After winding, it is covered with resin and then polished smooth to reduce friction and facilitate use. The reinforcing layer 11 is made of carbon fiber material. The reinforcing layer 11 is fixedly connected to the outside of piston rod 2, piston rod 3, and piston rod 4. The installation method of the reinforcing layer 11 on the outside of piston rod 2, piston rod 3, and piston rod 4 is the same as that of the cylinder 1. It is used to reduce the weight of the hydraulic cylinder, increase its strength, facilitate personnel use during rescue operations, and improve rescue efficiency.

[0036] Reference Figures 3-5 The sealing assembly includes a sealing cover 12, which is fixedly connected to the top of the cylinder 1. The sealing cover 12 is annular and is located on the outer periphery of the piston rod 2. A sealing ring 13 is installed on the inner side of the sealing cover 12. The sealing ring 13 is a lip seal structure. The piston rod 2 is slidably connected to the inner side of the sealing ring 13. The sealing ring 13 seals the gap between the piston rod 2 and the cylinder 1, preventing hydraulic oil from flowing out. Two sealing rings 9 are provided on the outer side of the piston rod 2. The two sealing rings 9 are located on the inner side of the cylinder 1. Each piston rod is provided with a sealing ring 9 on its outer side, forming a seal between the two piston rods. Multiple fixing screws 17 are installed in the middle of the sealing cover 12. The multiple fixing screws 17 are threaded into the inside of the cylinder 1. The sealing cover 12 is fixed to the top of the cylinder 1 by the multiple fixing screws 17 in the middle, which facilitates disassembly and provides installation space for the sealing rings 13.

[0037] Reference Figures 2-4A base 7, also made of aluminum alloy, is installed at the bottom of the cylinder 1. The base 7 has anti-slip textures 10 on its bottom, which protect the cylinder 1 and enhance stability during operation, making it easier to use. A locking block 15 is fixedly connected to the inner side of the base 7. The surface of the locking block 15 is smooth and flexible. A slot 16 is provided on the outer side of the cylinder 1, and the shape of the slot 16 corresponds to that of the locking block 15. The locking block 15 engages with the slot 16, and the base 7 is fixed in place by the cooperation of the locking block 15 and the slot 16. The bottom of cylinder 1 is protected, and a protective cover 8 is installed on the top of cylinder 1. The protective cover 8 is located outside the sealing ring 13. The protective cover 8 is installed in the same way as the base 7. The protective cover 8 can protect piston rod 1 2 and sealing cover 12. Piston rod 1 2, piston rod 2 3 and piston rod 3 4 are all provided with oil injection channels 14 in the middle. The oil injection channels 14 are connected to the oil injection pipe 2 6. When it is necessary to retract the extended piston rod, the oil injection pipe 2 6 is allowed to deliver hydraulic oil to the piston rod through the oil injection channel 14, so that the piston rod can be retracted in sequence.

[0038] Working principle: First, a reinforcing layer 11 made of carbon fiber material is provided on the outside of the cylinder 1 and each piston rod. After the winding is completed, a resin layer is applied to enhance the smoothness of the surface. At the same time, the internal cylinder body is made of high-strength aluminum alloy, which is not only lightweight but also strong. Then, the two ends of the carbon fiber material are set on the inside of the alloy cylinder body, and the carbon fiber material is protected by an alloy steel body to extend its service life.

[0039] Secondly, protective covers 8 and bases 7 are installed at the top and bottom of cylinder 1. Both protective covers 8 and bases 7 are removable. Pulling protective covers 8 outward will pull the inner locking block 15 out of the locking groove 16 on the outside of cylinder 1, thus removing protective covers 8 for easy cleaning and maintenance. The installation is done in reverse. The same applies to the removal and installation of bases 7. During use, the anti-slip texture 10 on the bottom of bases 7 will enhance the friction of the hydraulic cylinder, prevent the hydraulic cylinder from moving, and enhance stability.

[0040] 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.
