Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic cylinder control, and in particular relates to a horizontally arranged combined energy-saving hydraulic cylinder and a control system. Background Art

[0002] The hydraulic cylinder is the actuator in the hydraulic transmission system. It is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic cylinder includes a hydraulic cylinder body, which has a cylinder barrel and a piston, and a piston rod connected to the piston. When the hydraulic cylinder is used to achieve reciprocating motion, the reduction device can be eliminated and there is no transmission gap. Therefore, it has been widely used in the hydraulic systems of various machines.

[0003] At present, most hydraulic cylinders have only one set of cylinder barrels and pistons. During use, sometimes a hydraulic cylinder needs to support a larger area. Since the area supported by a set of hydraulic cylinders is small, the supporting surface often runs unsteadily and tilts, affecting the working effect. Therefore, combined hydraulic cylinders gradually appear, using multiple cylinder barrels to jointly support the same surface to solve the above problems. However, traditional hydraulic cylinders are fixed on mechanical equipment, and the vibrations generated when the mechanical equipment is working are transmitted to each other through the connecting parts, thereby reducing the stability of the hydraulic cylinder. Since the hydraulic cylinder has a large kinetic energy when it moves to the end point, the sudden stop of the piston movement inside the hydraulic cylinder will cause the hydraulic oil to hit the piston surface and cause an impact, resulting in the occurrence of water hammer effect, which ultimately affects the stability of the hydraulic cylinder.

[0004] The existing hydraulic cylinder has only one set of cylinder barrel and piston, which cannot meet the requirements of supporting a larger area of ​​operation. The supporting surface is often unstable and tilted. At the same time, the hydraulic cylinder is affected by the vibration of mechanical equipment during operation, and the hydraulic oil is prone to water hammer effect inside the cylinder body, which affects the stability of the hydraulic cylinder during operation. For this reason, the present invention proposes a horizontally arranged combined energy-saving hydraulic cylinder and control system. Summary of the invention

[0005] The purpose of the present invention is to provide a horizontally arranged combined energy-saving hydraulic cylinder and control system to solve the problem that the existing hydraulic cylinder has only one set of cylinder barrel and piston, cannot meet the requirements of supporting a larger area of ​​operation, and often causes the supporting surface to be unstable and tilted. At the same time, the hydraulic cylinder is affected by the vibration of mechanical equipment during operation, and the hydraulic oil is very likely to have a water hammer effect inside the cylinder body, which affects the stability of the hydraulic cylinder during operation.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention discloses a horizontally arranged combined energy-saving hydraulic cylinder, comprising a base and a support plate, wherein a group of main cylinder components and two groups of auxiliary cylinder components are arranged between the base and the support plate, the two groups of auxiliary cylinder components are respectively located on both sides of the main cylinder component, and the main cylinder component and the auxiliary cylinder component are connected through a channel; a rotating component and a shock absorbing component are arranged inside the main cylinder component; the base and the support plate serve as fixed installation parts of the hydraulic cylinder, the base is used to install and fix the main cylinder component and the auxiliary cylinder component, the support plate is pushed by the main cylinder component and the auxiliary cylinder component to be telescopically moved, and the mounting ring is used to connect mechanical equipment that needs to be movable; the channel is used to connect the main cylinder barrel and the auxiliary cylinder barrel, and after the main cylinder barrel and the auxiliary cylinder barrel are connected, the hydraulic oil can flow from the main cylinder barrel to the auxiliary cylinder barrel; The master cylinder assembly includes a master cylinder and a cylinder seat. The cylinder seat is installed through the center position of the base, and one end of the cylinder seat is welded to the master cylinder. The inner surface of the cylinder seat is beveled. The master cylinder serves as the main component of the combined hydraulic cylinder. The interior of the master cylinder is used for the sliding of the piston, and the interior of the cylinder seat is used for installing the rotating component. Since the inner surface of the cylinder seat is beveled, the shape of the internal cross-section of the cylinder seat is a funnel shape, with a smaller opening near the telescopic motor position and a larger opening at the other end. In this way, when the hydraulic oil enters the cylinder seat from the main cylinder oil inlet pipe, the flow rate of the hydraulic oil gradually decreases, because the inner diameter of the cylinder seat is getting larger and larger. When the hydraulic oil is poured from the main cylinder oil inlet pipe into the cylinder seat at a stable and uniform speed, the flow rate of the hydraulic oil is inversely proportional to the size of the pipe diameter. Since the hydraulic oil pouring flow rate remains unchanged, the larger the pipe diameter, the smaller the flow rate of the hydraulic oil flowing through. In a stable flow system, the flow rate Q is equal to the flow rate V multiplied by the pipe diameter A , where A is the cross-sectional area of ​​the pipe, which is the cross-sectional area of ​​the cylinder seat in the present invention, usually expressed as πr², where r is the radius of the cylinder seat, so the flow rate Q can be expressed as Q=V×πr². When the flow rate Q remains unchanged, when the pipe diameter A increases, the flow velocity V will decrease, and vice versa, when the pipe diameter A decreases, the flow velocity will increase; At the same time, the flow rate of the hydraulic oil also affects the rotation speed of the spiral turbine blades. When the hydraulic oil flows through the spiral turbine blades to drive them to rotate, the kinetic energy of the hydraulic oil is converted into the rotational kinetic energy of the spiral turbine blades. The faster the flow rate, the greater the driving force on the spiral turbine blades, thereby increasing the rotation speed of the spiral turbine blades. According to the above two points, in the present invention, when the spiral turbine blade is closer to the telescopic motor, the speed of the spiral turbine blade is higher, because the closer the distance is, the smaller the diameter of the pipe inside the cylinder seat where the spiral turbine blade is located, the smaller the diameter, the faster the flow rate of the hydraulic oil, and the faster the speed of the spiral turbine blade is driven. On the contrary, when the spiral turbine blade is farther away from the telescopic motor, the larger the diameter of the pipe inside the cylinder seat, the slower the flow rate of the hydraulic oil, and the slower the speed of the spiral turbine blade is driven. The rotating assembly includes a first telescopic rod, which is arranged inside the cylinder seat and located on the central axis of the cylinder seat. One end of the first telescopic rod is rotatably connected to one end of a spiral turbine blade, and the spiral turbine blade is a conical structure. The other end of the spiral turbine blade is welded to one end of a second telescopic rod, and the other end of the second telescopic rod is connected to a shock absorbing assembly. The first telescopic rod is used to drive the spiral turbine blade to slide inside the cylinder seat, so that the spiral turbine blade is located at positions with different inner diameters inside the cylinder seat. The second telescopic rod serves to connect the shock absorbing assembly. When the first telescopic rod is extended, the second telescopic rod is contracted. Conversely, when the first telescopic rod is contracted, the second telescopic rod is extended. The shock absorbing assembly includes a mounting post, one end of which is fixedly connected to the other end of the second telescopic rod, and sleeves are respectively welded to the opposite ends of the circumferential side surface of the mounting post, one end of the sleeve is movably connected to the telescopic block, and a shift block is installed at the outermost end of the telescopic block; the mounting post is used to connect the second telescopic rod, and the mounting post rotates under the drive of the rotating assembly, thereby driving the remaining shock absorbing assemblies installed on its surface to rotate, and the faster the rotating speed of the rotating assembly, the faster the rotating speed of the shock absorbing assembly; when the speed gradually becomes faster and faster, the telescopic block inside the sleeve is gradually thrown out of the sleeve due to the influence of centrifugal force, and the telescopic block and the main The distance between the inner walls of the cylinder barrel becomes closer and closer until the shift block contacts the stop block. During the rotation process, the shift block pushes the stop block to move, thereby driving the baffle to move into the installation groove. Since the shift block is in rotational motion, the motion trajectory is an arc, and the stop block moves vertically up and down. Therefore, when the shift block pushes the stop block to drive the baffle to move into the installation groove, the shift block will eventually leave the stop block surface and no longer contact it, and will not be stuck by the stop block; when the baffle moves toward the installation, the channel between the main cylinder and the auxiliary cylinder is opened, so the hydraulic oil can flow from the main cylinder to the auxiliary cylinder, and the rebound piece is used to reset the rebound baffle, and the rebound speed is slow.

[0007] Preferably, the master cylinder assembly also includes a master cylinder oil inlet pipe, one end of the master cylinder oil inlet pipe is installed at the bottom position of the cylinder seat, and the other end of the master cylinder oil inlet pipe is used to connect a hydraulic oil pump; a master cylinder oil outlet pipe is installed on the outside of the end of the master cylinder barrel away from the cylinder seat, and the other end of the master cylinder oil outlet pipe is also used to connect a hydraulic oil pump; a master piston is movably connected to the inside of the master cylinder barrel, one side of the master piston is fixedly connected to one end of the main piston rod, the other end of the main piston rod passes through the master cylinder cover to the outside of the master cylinder barrel, and is welded to a side of the support plate; the master cylinder cover is welded to an opening position on one side of the master cylinder barrel, and is adjacent to the master cylinder oil outlet pipe.

[0008] Preferably, the auxiliary cylinder assembly includes an auxiliary cylinder barrel, the outer diameter of which is smaller than the outer diameter of the main cylinder barrel; one end of the auxiliary cylinder barrel is welded to the inside of the base, the bottom of the auxiliary cylinder barrel is connected to one end of the auxiliary cylinder oil inlet pipe, and a auxiliary cylinder oil outlet pipe is installed on the other end of the peripheral side of the auxiliary cylinder barrel, and a auxiliary piston is slidably connected to the inner side of the auxiliary cylinder barrel, and a auxiliary piston rod is welded to one side of the auxiliary piston, and the other end of the auxiliary piston rod passes through the auxiliary cylinder cover to the outside of the auxiliary cylinder barrel; the auxiliary cylinder cover is sleeved on one side of the auxiliary cylinder barrel, and the auxiliary cylinder cover is adjacent to the auxiliary cylinder oil outlet pipe; an elongated circular groove is opened inside the auxiliary piston rod, and a connecting rod is slidably connected inside the elongated circular groove, and one end of the connecting rod is welded to the side of the support plate.

[0009] Preferably, the rotating assembly also includes a telescopic motor, which is fixedly connected to the bottom of the cylinder seat, and the output end of the telescopic motor passes through the bottom surface of the cylinder seat to the inside thereof, and is fixedly connected to one end of the first telescopic rod; the first telescopic rod, spiral turbine blades, second telescopic rod, mounting column and main piston rod are located on the same central axis.

[0010] Preferably, the shock absorbing assembly includes a connecting bridge, both ends of which are fixedly connected to the inner wall of the main cylinder, and a rotation groove is opened at the center position of one side of the connecting bridge, and one end of the mounting column is rotatably connected to the inside of the rotation groove.

[0011] Preferably, a rectangular groove is opened inside the sleeve, an elastic part is installed inside the rectangular groove, and the telescopic block is telescopically arranged inside the rectangular groove; in a stationary state, the telescopic block is contracted inside the rectangular groove, and the faster the rotating component rotates, the greater the centrifugal force generated on the telescopic block, and the more the telescopic block extends.

[0012] Preferably, the main cylinder is connected and penetrated with the auxiliary cylinder through a channel, and an installation groove is provided at the connection position of the main cylinder and the channel, a rebound part is installed inside the installation groove, the top of the rebound part is connected to the baffle, the baffle is movably arranged inside and outside the installation groove, the inner side of the baffle is connected to a block, and the block is movably connected to the shift block.

[0013] A control system for a horizontally arranged combined energy-saving hydraulic cylinder includes a main control module, a command module, a judgment module and a hydraulic oil output module that establish communication control connections with the main control module; Main control module: used to receive various working data of the hydraulic cylinder and output control commands of other modules of the control system; Command module: used to issue relevant control commands to the hydraulic cylinder according to real-time work requirements; Judgment module: used to judge and control the rotation speed of the hydraulic cylinder rotating assembly according to real-time work requirements; Hydraulic oil output module: used to control the output of hydraulic oil according to real-time work requirements; Among them, the real-time working requirements of the hydraulic cylinder include the output stroke of the hydraulic cylinder and the response speed of the hydraulic cylinder piston.

[0014] The present invention has the following beneficial effects: 1. The present invention can satisfy the requirement that the support plate of the combined hydraulic cylinder supports larger mechanical equipment by providing the main cylinder assembly and the auxiliary cylinder assembly, thereby making the use range of the hydraulic cylinder wider and the use effect more stable; 2. The present invention sets a rotating component. According to the real-time working requirements of the hydraulic cylinder, when the output stroke of the hydraulic cylinder is long and the response speed of the hydraulic cylinder piston is required to be fast, the output per unit time of the hydraulic oil is large. This will cause the hydraulic oil to hit the piston at a relatively fast speed after the piston runs to the specified stroke. Therefore, by controlling the rotation speed of the rotating component, the spiral turbine blades are placed at a position with a smaller inner diameter of the cylinder seat, and the rotation speed of the spiral turbine blades is accelerated, thereby driving the speed of the shock absorbing component to increase. When the shock absorbing component rotates faster, the centrifugal force is greater, and the telescopic block drives the shift block to hit the block at a faster speed, driving the block to move and open the baffle. After the baffle is opened, the hydraulic oil enters the interior of the auxiliary cylinder from the channel. Therefore, when the hydraulic oil stops outputting, the hydraulic oil inside the main cylinder no longer has a water hammer effect, but moves from the inside of the channel to the auxiliary cylinder, thereby reducing the impact force of the water hammer effect; the cylinder operation is more stable, and the two auxiliary cylinders jointly bear the impact force generated by the water hammer effect, so that the hydraulic oil has a venting channel.

[0015] 3. In the present invention, when the output stroke of the hydraulic cylinder is short and the hydraulic cylinder piston response speed is required to be slow, the rotation speed of the rotating component can be reduced. It is only necessary to speed up the rotation speed of the rotating component while stopping the injection of hydraulic oil to achieve the purpose of the shift block to shift the block, so that the baffle is opened, and the hydraulic oil is injected from the channel into the auxiliary cylinder to alleviate the water hammer effect. During the hydraulic oil injection process, the baffle is always kept closed, and the hydraulic oil is not injected into the auxiliary cylinder, thereby reducing the flow rate of the hydraulic oil, thereby reducing the energy output and achieving energy saving. Since no hydraulic oil is injected into the auxiliary cylinder, when the main piston rod pushes the support plate, the support plate drives the connecting rod connected thereto to extend out from the inside of the auxiliary piston rod. This process is also applicable to the operation of mechanical equipment with a smaller support surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-8 The present invention is a horizontally arranged combined energy-saving hydraulic cylinder, comprising a base 1 and a support plate 2, wherein a group of main cylinder components and two groups of auxiliary cylinder components are arranged between the base 1 and the support plate 2, the two groups of auxiliary cylinder components are respectively located on both sides of the main cylinder component, and the main cylinder component and the auxiliary cylinder component are connected through a channel 30; a rotating component and a shock absorbing component are arranged inside the main cylinder component; the base 1 and the support plate 2 serve as fixed installation parts of the hydraulic cylinder, the base 1 is used to install and fix the main cylinder component and the auxiliary cylinder component, the support plate 2 is pushed by the main cylinder component and the auxiliary cylinder component to be telescopically moved, and the mounting ring 3 is used to connect the mechanical equipment that needs to be movable; the channel 30 is used to connect the main cylinder barrel 4 and the auxiliary cylinder barrel 11, and after the main cylinder barrel and the auxiliary cylinder barrel 11 are connected, the hydraulic oil can flow from the main cylinder barrel 4 to the auxiliary cylinder barrel 11; The master cylinder assembly includes a master cylinder barrel 4 and a cylinder seat 5. The cylinder seat 5 is installed through the center position of the base 1, and one end of the cylinder seat 5 is welded to the master cylinder barrel 4; the inner surface of the cylinder seat 5 is beveled, and the master cylinder barrel 4 is the main component of the combined hydraulic cylinder. The interior of the master cylinder barrel 4 is used for the sliding of the piston, and the interior of the cylinder seat 5 is used to install the rotating component. Since the inner surface of the cylinder seat 5 is beveled, the shape of the internal cross-section of the cylinder seat 5 is a funnel shape, with a smaller opening near the telescopic motor 18 and a larger opening at the other end. In this way, when the hydraulic oil enters the cylinder seat 5 from the master cylinder oil inlet pipe 6, the flow rate of the hydraulic oil gradually decreases, because the inner diameter of the cylinder seat 5 is getting larger and larger. When the hydraulic oil is poured from the master cylinder oil inlet pipe 6 to the cylinder seat 5 at a stable and uniform speed, the flow rate of the hydraulic oil is inversely proportional to the size of the pipe diameter. Since the hydraulic oil pouring flow rate remains unchanged, the larger the pipe diameter, the smaller the flow rate of the hydraulic oil flowing through. In a stable flow system, the flow rate Q is equal to the flow rate V multiplied by the pipe diameter A , where A is the cross-sectional area of ​​the pipe, which is the cross-sectional area of ​​the cylinder base 5 in the present invention, and is usually expressed as πr², where r is the radius of the cylinder base 5, so the flow rate Q can be expressed as Q=V×πr². When the flow rate Q remains unchanged, when the pipe diameter A increases, the flow velocity V will decrease, and vice versa, when the pipe diameter A decreases, the flow velocity will increase; At the same time, the flow rate of the hydraulic oil also affects the rotation speed of the spiral turbine blade 20. When the hydraulic oil flows through the spiral turbine blade 20 to drive it to rotate, the kinetic energy of the hydraulic oil is converted into the rotational kinetic energy of the spiral turbine blade 20. The faster the flow rate, the greater the driving force on the spiral turbine blade 20, thereby increasing the rotation speed of the spiral turbine blade 20. According to the above two points, in the present invention, when the spiral turbine blade 20 is closer to the telescopic motor 18, the rotation speed of the spiral turbine blade 20 is higher, because the closer the distance is, the smaller the diameter of the pipe inside the cylinder seat 5 where the spiral turbine blade 20 is located, the smaller the diameter, the faster the flow rate of the hydraulic oil, and the faster the rotation speed of the spiral turbine blade 20 is driven. On the contrary, when the spiral turbine blade 20 is farther away from the telescopic motor 18, the larger the diameter of the pipe inside the cylinder seat 5, the slower the flow rate of the hydraulic oil, and the slower the rotation speed of the spiral turbine blade 20 is driven. The rotating assembly includes a first telescopic rod 19, which is arranged inside the cylinder base 5 and located on the central axis of the cylinder base 5. One end of the first telescopic rod 19 is rotatably connected to one end of a spiral turbine blade 20. The spiral turbine blade 20 is a conical structure. The other end of the spiral turbine blade 20 is welded to one end of a second telescopic rod 21. The other end of the second telescopic rod 21 is connected to the shock absorbing assembly. The first telescopic rod 19 is used to drive the spiral turbine blade 20 to slide inside the cylinder base 5, so that the spiral turbine blade 20 is located at positions with different inner diameters inside the cylinder base 5. The second telescopic rod 21 serves to connect the shock absorbing assembly. When the first telescopic rod 19 is extended, the second telescopic rod 21 is contracted. Conversely, when the first telescopic rod 19 is contracted, the second telescopic rod is extended.

The shift block 26 moves the stopper 29 and the baffle 28 moves toward the inside of the installation groove. Since the shift block 26 is in rotational motion, the motion trajectory is an arc, and the baffle 29 moves vertically up and down. Therefore, when the shift block 26 moves the baffle 29 and drives the baffle 28 to move toward the inside of the installation groove, the shift block 26 will eventually leave the surface of the baffle 29 and no longer contact it, and will not be stuck by the baffle; when the baffle 28 moves toward the inside of the installation, the channel 30 between the main cylinder 4 and the auxiliary cylinder 11 is opened, so the hydraulic oil can flow from the main cylinder 4 to the auxiliary cylinder 11, and the rebound member 27 is used to rebound the baffle 28 to reset, and the rebound speed is slow.
