Description

Technical Field

[0001] This utility model relates to an integrated cartridge valve block hydraulic cylinder, and pertains to the field of hydraulic cylinder technology. Background Technology

[0002] In hydraulic systems, the cylinder is the actuator. Oil from the pump controls the opening and closing of the electrical control valve, thereby achieving accurate control of the cylinder. Currently, there are many types of cylinders on the market to meet different needs. Traditional cylinders often use split valve groups or single cartridge valve structures for inlet and outlet oil pipe control, which cannot achieve simultaneous opening and closing control of two oil circuits. The performance needs to be improved, especially when the hydraulic system experiences sudden high pressure or leakage. Relying solely on an external single valve body structure for protection cannot provide synchronous control according to usage requirements. Incomplete sealing of the cylinder can easily lead to safety hazards. Therefore, it is necessary to propose an integrated cartridge valve block cylinder for improvement. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an integrated cartridge valve block cylinder to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: an integrated cartridge valve block cylinder, including a cylinder body, a first inlet / outlet oil pipe and a second inlet / outlet oil pipe connected to the left and right sides of the cylinder body, a vertical cylinder integrally provided in the middle of the cylinder body, and the first inlet / outlet oil pipe and the second inlet / outlet oil pipe are respectively connected to the vertical cylinder and communicate with the inner side of the vertical cylinder, a movable valve cylinder is adapted to be embedded in the middle of the vertical cylinder from top to bottom, and a left oil pipe joint and a right oil pipe joint are respectively connected and installed on the left and right sides of the movable valve cylinder;

[0005] The inner side of the movable valve cylinder is provided with an inverted T-shaped partition that protrudes downwards, dividing the inner side of the movable valve cylinder into a left channel and a right channel that are separately connected to the left oil pipe joint and the right oil pipe joint. When the movable valve cylinder is embedded in the installation cylinder, the bottom of the inverted T-shaped partition abuts against the bottom of the inner side of the cylinder, and the bottom of the left channel and the right channel are respectively connected to the first inlet and outlet oil pipe and the second inlet and outlet oil pipe.

[0006] The pistons inside the left and right channels are equipped with piston plugs, and a push-pull assembly for pushing and pulling the piston plugs and raising and lowering the piston is installed on the top of the movable valve cylinder.

[0007] Furthermore, the push-pull assembly includes an outer bracket locked and installed on the top of the movable valve cylinder, and an electric push rod is installed on the top of the outer bracket. A push-pull plate is installed on the telescopic end of the electric push rod, and the push-pull plate is located inside the outer bracket and above the movable valve cylinder. Two vertically arranged movable inserts are fixed at the bottom of the push-pull plate, which slide through the inner side of the movable valve cylinder and are fastened to the piston plug.

[0008] Furthermore, when the electric push rod is pushed down, the two piston plugs simultaneously block the junction of the left oil pipe joint and the left channel, as well as the junction of the right oil pipe joint and the right channel.

[0009] Furthermore, a sealing sheet is laminated to the bottom surface of the push-pull plate.

[0010] Furthermore, an external connecting piece is integrally provided on the outer circumference of the middle part of the movable valve cylinder, and is connected to the upper flange of the vertical cylinder through the external connecting piece.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model features a vertical cylinder on its cylinder body for use with a movable valve cylinder and a push-pull assembly. An inverted T-shaped partition divides the inner side of the movable valve cylinder into a left channel and a right channel, allowing the first inlet / outlet oil pipe to connect with the left oil pipe connector and the second inlet / outlet oil pipe to connect with the right channel. In conjunction with the push-pull assembly, the synchronous piston lifting and lowering of the two piston plugs is achieved, simultaneously sealing the junction between the first inlet / outlet oil pipe and the left channel, and the junction between the right oil pipe connector and the right channel. This enables synchronous control of the opening and closing of the oil circuits of the first and second inlet / outlet oil pipes, allowing for control of the oil circuit opening and closing according to usage requirements, or for emergency braking.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-3This utility model provides a technical solution for an integrated cartridge valve block cylinder: it includes a cylinder body 1, a first inlet / outlet oil pipe 2 and a second inlet / outlet oil pipe 3 connected to the left and right sides of the cylinder body 1, a vertical cylinder 4 integrally provided in the middle of the cylinder body 1, and the first inlet / outlet oil pipe 2 and the second inlet / outlet oil pipe 3 are respectively connected to the vertical cylinder 4 and communicate with the inner side of the vertical cylinder 4. A movable valve cylinder 5 is fitted into the middle of the vertical cylinder 4 from top to bottom, and a layer of anti-leakage rubber gasket can be provided on the inner side of the vertical cylinder 4 to make the embedded connection tighter. At the same time, an outer connecting piece 10 is integrally provided on the outer circumference of the middle of the movable valve cylinder 5, so that the bottom of the movable valve cylinder 5 is embedded into the inner side of the vertical cylinder 4 for tight connection, and is connected to the upper flange of the vertical cylinder 4 through the outer connecting piece 10. When the flange is connected, an O-ring can be placed between them.

[0020] The movable valve cylinder 5 has a left oil pipe connector 6 and a right oil pipe connector 7 installed on its left and right sides, respectively. The left and right oil pipe connectors 6 and 7 are connected to an external oil pump via oil pipes. An inverted T-shaped baffle 51 is provided on the inner side of the movable valve cylinder 5, protruding downwards. This inverted T-shaped baffle 51 divides the inner side of the movable valve cylinder 5 into a left channel 61 and a right channel 71, each communicating separately with the left and right oil pipe connectors 6 and 7. When the movable valve cylinder 5 is embedded in the vertical cylinder 4, the bottom of the inverted T-shaped baffle 51 abuts against the bottom of the inner side of the vertical cylinder 4, allowing for... The cylinder is tightly connected and simultaneously divides the vertical cylinder 4 into two separate cavities that communicate with the left channel 61 and the right channel 71. The bottom of the left channel 61 is connected to the first inlet / outlet oil pipe 2, and the bottom of the right channel 71 is connected to the second inlet / outlet oil pipe 3. A piston plug 8 is provided on the piston inside the left channel 61 and the right channel 71, and a push-pull assembly 9 for pushing and pulling the piston plug 8 to rise and fall is installed on the top of the movable valve cylinder 5. The first inlet / outlet oil pipe 2 and the second inlet / outlet oil pipe 3 are blocked by the movable rising and falling position of the piston plug 8.

[0021] Specifically, the push-pull assembly 9 includes an outer bracket 91 locked to the top of the movable valve cylinder 5, and an electric push rod 92 is mounted on the top of the outer bracket 91. A push-pull plate 93 is mounted on the telescopic end of the electric push rod 92, and the push-pull plate 93 is located inside the outer bracket 91 and above the movable valve cylinder 5. Two vertically arranged movable inserts 94 are fixed at the bottom of the push-pull plate 93. The two movable inserts 94 slide through the inner side of the movable valve cylinder 5 and are fastened to the piston plug 8. When the electric push rod 92 is pushed down, the push-pull plate 93 pushes the two movable inserts 94 and the two piston plugs 8 along the left channel 61. The right channel 71 moves downward, allowing the two piston plugs 8 to simultaneously block the junction of the left oil pipe joint 6 and the left channel 61, as well as the junction of the right oil pipe joint 7 and the right channel 71. In other words, while the bottom surface of the piston plug 8 blocks the left channel 61 and the right channel 71, the side surface of the piston plug 8 simultaneously blocks the pipe openings of the left oil pipe joint 6 and the right oil pipe joint 7. This results in a better sealing effect. Furthermore, a sealing sheet 931 is laminated on the bottom surface of the push-pull plate 93. The push-pull plate 93 is tightly abutted against the top of the movable valve cylinder 5 through the sealing sheet 931, which can further improve the sealing performance of the left channel 61 and the right channel 71.
