Description
Technical Field

[0002] The oil cylinder (hydraulic cylinder) is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application, and other devices are indispensable.
[0003] Based on the above-mentioned related technologies, the applicant believes that the existing oil cylinder lacks an auxiliary buffer mechanism. Since the action and reaction forces exerted on the pile body during use instantly generate huge impact force, and the impact force acts on the outrigger oil cylinder, the oil pressure in the pressure chamber of the outrigger oil cylinder instantly rises. When the oil pressure reaches a certain value, the cylinder barrel of the outrigger oil cylinder will be permanently swollen and deformed or directly burst, resulting in serious machine damage accidents. To address the above problems, we have launched a rear support oil cylinder with gas-liquid buffering function. Utility Model Content

[0021] Reference Figure 1 - Figure 4, A rear support oil cylinder with a gas-liquid buffer function, including an oil cylinder body 1. A buffer column 2 is fixedly connected to the bottom of the oil cylinder body 1. A telescopic end 3 is provided at the top of the oil cylinder body 1. A connection port 4 is provided between the oil cylinder body 1 and the buffer column 2. A buffer mechanism 5 is provided on the outside of the oil cylinder body 1. The buffer mechanism 5 includes a first buffer assembly and a second buffer assembly. The first buffer assembly and the second buffer assembly are used in cooperation. The first buffer assembly includes a first spring 51. The first spring 51 is arranged inside the buffer column 2. The bottom of the first spring 51 is fixedly connected to the bottom inner wall of the buffer column 2. A lifting disc 52 is slidably connected inside the buffer column 2. The bottom of the lifting disc 52 is fixedly connected to the top of the first spring 51. A rubber sealing ring 53 is fixedly connected to the top of the lifting disc 52. Slide columns 54 are symmetrically and fixedly connected inside the buffer column 2. The slide columns 54 and the lifting disc 52 are slidably connected. An oil injection port 55 is fixedly connected to the outside of the buffer column 2. The second buffer assembly includes a blocking frame 6. The blocking frame 6 is fixedly connected to the top of the telescopic end 3. A second spring 8 is sleeved outside the telescopic end 3. The bottom of the second spring 8 is fixedly connected to a supporting ring 9. The bottom of the supporting ring 9 is fixedly connected to the top of the oil cylinder body 1.
[0022] In the above technical solution, considering that there is a lack of an auxiliary buffer mechanism in the existing oil cylinder, due to the huge impact force generated instantaneously by the action and reaction forces received by the pile body during use, and the impact force acts on the leg oil cylinder, resulting in an instantaneous increase in the oil pressure in the pressure chamber of the leg oil cylinder. When the oil pressure reaches a certain value, it causes permanent swelling deformation or direct bursting of the cylinder barrel of the leg oil cylinder, thus causing serious machine damage accidents. To solve such problems, the specific operations are as follows:
[0023] Refer to Figure 1 - Figure 4 , In a preferred embodiment, the telescopic end 3 telescopes inside the oil cylinder body 1. When a large force is applied inside the oil cylinder body 1, the oil in the oil cylinder body 1 enters the inside of the buffer column 2 through the connection port 4. The oil squeezes the rubber sealing ring 53 downward. The rubber sealing ring 53 drives the lifting disc 52 to slide downward on the outside of the slide column 54. Thus, the lifting disc 52 squeezes the oil downward to buffer the force. At the same time, the lifting disc 52 squeezes the first spring 51 downward, and the first spring 51 assists in buffering the force. During the contraction process of the telescopic end 3, the first spring 51 is pressed downward by the blocking frame 6, and the first spring 51 buffers and filters the telescopic force of the telescopic end 3, preventing the telescopic end 3 from directly hitting the oil cylinder body 1. By providing the buffer mechanism 5, it is possible to buffer and filter the impact force generated during the operation of the oil cylinder body 1, avoid damage to the oil cylinder body 1 caused by direct impact, extend the service life of the oil cylinder body 1, ensure the normal use of the oil cylinder body 1, with a simple structure and strong practicability.
[0024] Refer to Figure 1 -Figure 4 , in a preferred embodiment, a chassis 10 is fixedly connected to the bottom of the buffer column 2, an installation frame 11 is fixedly connected to the bottom of the chassis 10, and installation holes 12 are symmetrically formed inside the installation frame 11. A connection ring 7 is fixedly connected to the top of the blocking frame 6. A rubber pad for buffering is fixedly connected to the top of the supporting ring 9. The oil cylinder body 1 is electrically connected to an external controller. By providing the installation frame 11 and the installation holes 12, it is convenient to install and connect the oil cylinder body 1 to the outside. The rubber pad provided can assist in buffering. By providing the controller, it is convenient for the staff to control the opening and closing of the oil cylinder body 1, and the operation is more convenient.
[0025] Working principle: In actual use, the staff first installs the oil cylinder body 1 at the position where it is needed through the installation frame 11 and the installation holes 12, injects oil into the inside of the buffer column 2 through the oil injection port 55, and then starts the oil cylinder body 1. The telescopic end 3 telescopes inside the oil cylinder body 1. When a large force is applied inside the oil cylinder body 1, the oil inside the oil cylinder body 1 enters the inside of the buffer column 2 through the connection port 4. The oil squeezes the rubber sealing ring 53 downward, and the rubber sealing ring 53 drives the lifting disc 52 to slide downward on the outside of the sliding column 54. Thus, the lifting disc 52 squeezes the oil downward to buffer the force. At the same time, the lifting disc 52 squeezes the first spring 51 downward, and the first spring 51 assists in buffering the force. During the contraction process of the telescopic end 3, the first spring 51 is pressed downward by the blocking frame 6, and the first spring 51 buffers and filters the telescopic force of the telescopic end 3 to prevent the telescopic end 3 from directly hitting the oil cylinder body 1.

The substitution may be a substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
