Description

Technical Field

[0001] This invention relates to the field of hydraulic system technology, specifically to a multi-cylinder synchronized hydraulic system. Background Technology

[0002] A multi-cylinder synchronized hydraulic system is a hydraulic control system that uses hydraulic power to drive multiple hydraulic cylinders to achieve strict synchronization of their movement displacement, speed, or output force.

[0003] Existing hydraulic systems lack low-cost adaptive oil supply pressure regulation devices. Fluctuations in the flow rate of hydraulic pump groups and slight dynamic changes in the load of hydraulic cylinders can cause fluctuations in oil supply pressure. These fluctuations are directly transmitted to each hydraulic cylinder, reducing the accuracy of system synchronization. Existing pressure stabilization solutions mostly rely on components such as servo valves, which are complex in structure and expensive, making them difficult to adapt to low-cost application scenarios.

[0004] Furthermore, existing hydraulic systems lack effective pipeline leakage protection capabilities. When a branch hydraulic oil pipe bursts, it will cause a large amount of hydraulic oil to leak, resulting in waste. At the same time, it will cause the normal oil circuit of the entire system to depressurize, ultimately leading to the simultaneous failure of multiple oil cylinders, or even causing safety accidents such as load overturning.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 15This embodiment describes a multi-cylinder synchronized hydraulic system, including a hydraulic oil tank 1. A hydraulic pump assembly 2 is fixedly installed on the upper surface of the hydraulic oil tank 1. The hydraulic pump assembly 2 can be driven by a motor to deliver hydraulic oil. The hydraulic pump assembly 2 is existing technology and will not be described in detail here. A hydraulic solenoid valve assembly 4 is fixedly installed on the upper surface of the hydraulic oil tank 1. The hydraulic solenoid valve assembly 4 has the ability to control the pressure, flow rate, and flow direction of the hydraulic oil, thereby ensuring the stability of the hydraulic oil pressure and the precise and synchronized operation of the hydraulic cylinders. The hydraulic solenoid valve assembly 4 is existing technology and will not be described in detail here. A delivery pipe 5 is fixedly connected to the output end of the hydraulic solenoid valve assembly 4. The delivery pipe 5 is located away from the hydraulic solenoid valve. Group 4 is fixedly connected to a synchronous flow divider motor mechanism 6. The synchronous flow divider motor mechanism 6 includes a synchronous flow divider motor 61, which is existing technology and will not be described in detail here. The synchronous flow divider motor 61 can evenly divide the hydraulic oil delivered from the delivery pipeline 5 to ensure that each hydraulic cylinder can operate synchronously. The synchronous flow divider motor mechanism 6 also includes a differential pressure safety valve. The oil inlet of the differential pressure safety valve is connected to the output port 63, and the oil outlet of the differential pressure safety valve is connected to the flow divider pipe 7. Therefore, the differential pressure safety valve connected in series between the output port 63 and the flow divider pipe 7 can form a first-level protection effect for rapid control of the oil flow of this branch. The differential pressure safety valve is existing technology and will not be described in detail here. A synchronous flow divider motor 61 has several output ports 63 fixedly installed at one end. The end of each output port 63, furthest from the synchronous flow divider motor 61, is fixedly connected to a flow divider pipe 7. A solenoid valve 62 is fixedly installed on the outside of each output port 63. The solenoid valve 62 is a normally open type and can close the output ports 63, ensuring low hydraulic oil leakage after the flow divider pipe 7 ruptures, minimizing the difference in operating distance between hydraulic cylinders, and thus ensuring stable operation of the hydraulic cylinders while preventing hydraulic oil waste. The solenoid valve 62 is existing technology and will not be described in detail here. One end of the control mechanism 6 is fixedly connected to a diversion pipe 7, and the other end of the diversion pipe 7 is fixedly connected to a running component 8. The running component 8 includes an oil supply body 81, and an inverted T-shaped oil supply channel 85 is opened through the inside of the oil supply body 81. A connecting body 82 is fixedly installed on the upper surface of the oil supply body 81, and a running magnet 83 is fixedly installed on the upper end of the connecting body 82. The running magnet 83 is made of permanent magnet material, and its magnetic field strength can be selected according to actual use requirements to ensure that sufficient induced current can be generated when the rotor 91 rotates. This induced current is used to control the relay to engage, thereby triggering the solenoid valve 62 to act. A fixing body 84 is fixedly installed on the upper end of the running magnet 83. The fixing body 84 is used to support the spring 105. A spiral groove 86 is opened on the inner wall of the running magnet 83. The inner wall of the spiral groove 86 is slidably connected to one end of the guide block 93. Through the guidance of the spiral groove 86 and the sliding of the guide block 93, the rotor 91 can be rotated. The running component 8 is equipped with a protection mechanism 9 and an adjustment mechanism 10. The differential pressure safety valve is a first-level protection. Its reaction time is less than the time when the hydraulic oil leaks after the burst, causing the pressure to drop. Therefore, when the differential pressure safety valve is running normally, the protection mechanism 9 and the relay are in the standby state. However, when the differential pressure safety valve fails to close completely when the pipe bursts due to a fault, resulting in leakage, or when the differential pressure safety valve leaks, the pressure in the oil supply channel 85 will drop rapidly. At this time, the protection mechanism 9 generates current through the rotation of the rotor 91, triggering the relay to close the solenoid valve 62, thus achieving the effect of second-level protection. The protection mechanism 9 includes a rotor 91 located inside the running magnet 83. A fixed disk 92 is rotatably mounted inside the rotor 91. A return spring is provided between the fixed disk 92 and the support disk 104 to ensure the reset of the rotor 91 and the fixed disk 92. The return spring is existing technology and will not be described in detail here. The fixed disk 92 is used to transmit downward pulling force, thereby generating a downward pulling force on the rotor 91, ensuring that the rotor 91 can move downward and rotate. The fixed disk 92 has two sets of symmetrically distributed insertion ports 921 inside, with several insertion ports 921 in each set. The inner wall of the insertion port 921 is connected to one end of the connecting rod 98. The connecting rod 98 is telescopic. Due to the limit of the return spring 981, the connecting rod 98 is initially located inside the running port 106, thus ensuring that it can be inserted into the inner wall of the insertion port 921. At the same time, other connecting rods 98 can retract when squeezed, thus ensuring that the connecting rods 98 that need to be inserted into the inner wall of the insertion port 921 can run smoothly. The fixed plate 92 is slidably connected to the outside of the moving rod 103, so that when the slider 101 adjusts the pressure, the fixed plate 92 and the rotor 91 will not move, avoiding the situation of misjudgment of the shunt tube 7 bursting. A guide block 93 is fixedly installed on the outer surface of the rotor 91. A damping disc 94 is provided on the lower side of the fixed disc 92. The inside of the damping disc 94 is slidably connected to the outside of the moving rod 103. A push ring 95 is fixedly installed on the upper surface of the damping disc 94. The inside of the push ring 95 is slidably connected to the outside of the moving rod 103. Several damping holes 96 are opened through the inside of the damping disc 94. When the slider 101 is adjusted for pressure, its moving speed is slow and its moving amplitude is small. Therefore, it can ensure that ultrapure water can pass smoothly through the damping holes 96, and thus no damping effect is produced. When the diversion pipe 7 bursts and the hydraulic oil pressure drops rapidly, the rapidly moving slider 101... 01 can drive the damping disk 94 to move downward quickly. At this time, the moving speed is greater than the speed of ultrapure water passing through the damping hole 96, thereby restricting the movement of the damping disk 94 and producing a damping effect. Ultrapure water is provided on the upper side of the slider 101, inside the running magnet 83, and inside the fixed body 84. The adjustment mechanism 10 includes a moving rod 103. A support disk 104 is fixedly installed on the upper end of the moving rod 103. A spring 105 is fixedly installed on the side of the support disk 104 away from the moving rod 103. The end of the spring 105 away from the support disk 104 is fixedly connected to the inner wall of the fixed body 84. Two sets of symmetrically distributed operating ports 106 are provided on the outer side of the moving rod 103. A return spring 981 is fixedly installed on the inner wall of the operating port 106. A connecting rod 98 is fixedly connected to the end of the return spring 981 away from the inner wall of the operating port 106. A connecting slide rod 982 is fixedly installed on the side of the connecting rod 98 close to the return spring 981. The outer side of the connecting slide rod 982 is slidably connected to the inner wall of the sliding groove 1061, and one end of the connecting slide rod 982 extends into the guide groove 107. There are several operating ports 106 in each set, and the inner wall of the operating port 106 is provided with a sliding groove 1061. Two symmetrically distributed moving grooves 1071 are provided on the outer side of the moving rod 103. The moving grooves 1071 are connected to the inside of the guide groove 107. A slider 101 is fixedly installed at the lower end of the moving rod 103. The slider 101 has a sealing effect and is made of hydrogenated nitrile rubber, so it can ensure that ultrapure water will not leak into the hydraulic oil. An annular limiting block is provided on the lower side of the slider 101 to ensure the lowest position of the slider 101. The lowest position of the slider 101 is located at the intersection of the lower end of the vertical pipe and the middle of the horizontal pipe of the inverted T-shaped oil supply channel 85. A spring 102 is fixedly installed on the upper surface of the slider 101. The spring 102 is sleeved on the outer side of the moving rod 103. The end of the spring 102 away from the slider 101 is fixedly connected to the lower surface of the damping disk 94. The spring 102 initially only has the effect of maintaining the initial position of the damping disk 94. When damping is generated, the damping disk 94 is damped and stops moving. At this time, the spring 102 will be stretched and unfolded. The moving rod 103 has two symmetrically distributed guide grooves 107 inside. A push rod 97 is slidably installed inside the guide groove 107. A push block 971 is fixedly installed at the lower end of the push rod 97. The end of the push block 971 away from the push rod 97 extends to the outside of the moving groove 1071. Several protrusions 972 are fixedly installed on the outside of the push rod 97.

[0023] The working principle of the above embodiment is as follows: When the hydraulic cylinder is used, the hydraulic pump group 2 is started first. The hydraulic pump group 2 can draw out the hydraulic oil inside the hydraulic oil tank 1. Then the hydraulic oil enters the hydraulic solenoid valve group 4. The hydraulic oil through the hydraulic solenoid valve group 4 can enter the synchronous flow divider motor mechanism 6. Then the hydraulic oil can be divided through the output port 63, thereby ensuring the synchronous effect of multiple cylinders. When hydraulic oil enters the distributor pipe 7 through the output port 63 and then enters the oil supply channel 85, the slider 101 is pressured and begins to move upward. At the same time, the moving rod 103 and the spring 102 move upward. At this time, the damping plate 94 moves upward, and the support plate 104 moves upward. The spring 105 is pushed and begins to contract. Meanwhile, the rotor 91 and the fixed plate 92 remain stationary. When the hydraulic oil supply pressure fluctuates, when the hydraulic oil pressure rises, the slider 101 is pushed by the oil pressure, which can ensure that the cavity area inside the oil supply channel 85 increases. As a result, the hydraulic oil needs to occupy more space. At this time, the upward movement of the slider 101 can reduce the pressure of the high-pressure hydraulic oil, thereby ensuring the synchronous operation of multiple hydraulic cylinders. When the hydraulic oil pressure decreases, spring 105 pushes moving rod 103 to move, which in turn pushes slider 101 to move. The movement of slider 101 reduces the space inside the oil supply channel 85, thereby reducing the space occupied by the hydraulic oil and increasing the hydraulic oil pressure. This ensures the synchronous operation of the hydraulic cylinder. When a pipeline bursts, the differential pressure safety valve operates according to the pressure difference, thus blocking the output port 63. However, if the differential pressure safety valve is not completely blocked or leaks, the hydraulic oil inside the oil supply channel 85 continues to leak out, and the hydraulic oil pressure drops rapidly. At this time, spring 105 loses its thrust and quickly resets. Moving rod 103 moves downward rapidly, slider 101 moves downward rapidly, and spring 102 drives damping disc 94 to move downward. Since the moving rod 103 moves at a relatively fast speed, which is greater than the speed of ultrapure water passing through damping hole 96, the moving speed of pushing ring 95 and damping disc 94 decreases rapidly until they stop moving. At this time, spring 102 unfolds, and moving rod 103 continues to move. At the same time, push block 971 continues to move downward and is blocked by push ring 95. Push block 971 is blocked by push ring 95, and push block 971 is equivalent to being pushed upward. At this time, push block 971 moves upward, push rod 97 moves upward, and protrusion 972 on push rod 97 moves upward. Protrusion 972 squeezes connecting slide rod 982. At this time, connecting slide rod 982 pushes connecting rod 98 to move, and reset spring 981 unfolds. The pushed connecting rod 98 is inserted into socket 921. At this time, moving rod 103 continues to move and drives connecting rod 98 to move downward. At this time, connecting rod 98 drives fixed disk 92 to move downward, and fixed disk 92 drives rotor 91 to move. When the rotor 91 moves downward, the guide block 93 slides along the spiral groove 86, at which point the rotor 91 begins to rotate. The rotation of the rotor 91 generates current, which causes the relay to engage. A stop switch is connected in series in the power supply line of the relay. The stop switch is a normally closed push-button switch. At this time, the relay causes the solenoid valve 62 to operate and close the output port 63, thereby ensuring the stable operation of other hydraulic cylinders. The rotor 91, the relay, the solenoid valve 62, and the connection method of the three are existing technologies and will not be described in detail here. The relay is not shown in the figure. The relay adopts a self-locking circuit, which ensures that when the slider 101 stops moving, the rotor 91 stops rotating, and when the current disappears, the relay can still remain engaged. When it is necessary to open the solenoid valve 62, the stop switch can be pressed to open the solenoid valve 62. The stop switch, the self-locking circuit relay, and the connection method of the two are existing technologies and will not be described in detail here. At the same time, when the slider 101 moves to the lowest position, the damping disk 94 is damped and the spring 102 can pull the damping disk 94 to reset, and then the push block 971 loses its thrust, and the rotor 91 moves downward. At this time, under the reset of the reset spring 981, the connecting rod 98 is released from the insertion state with the socket 921, and the connecting rod 98 enters the running port 106. At the same time, under the reset of the reset tension spring, the rotor 91 moves upward to complete the reset.

[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
