Description

Technical Field

[0001] The invention relates to the technical field of oil distributors, and in particular to a multi-way hydraulic oil distributor and a control method thereof. Background Art

[0002] The multi-way hydraulic oil distributor, also called the multi-way control valve, is a hydraulic component used to distribute the pressure oil in the hydraulic system to different hydraulic actuators according to different requirements, and to control the movement direction, speed and force of these actuators. It is equivalent to the "traffic hub" of the hydraulic system, coordinating the work of various actuators.

[0003] According to the control mode, multi-way hydraulic oil distributors can be divided into manual control multi-way valves, hydraulic control multi-way valves and electric control multi-way valves. Among them, the manual control multi-way valve controls the position of the valve core through the manual operation handle to achieve the distribution and control of the oil. The operation is simple and direct, and it is often used in some small hydraulic equipment or occasions with low requirements for automation.

[0004] For example, a multi-way control valve that is easy to operate with Chinese patent announcement number CN117287533B relates to the field of multi-way control valves, including a valve body mechanism and an operating mechanism, including an oil circuit assembly on the surface of the valve seat, a safety valve located outside the valve seat, and a sliding valve located inside the valve seat; including a support member arranged on the outer wall of the valve seat, a connecting seat arranged on the outside of the support member, a connecting rod member arranged on the inside of the connecting seat, and a first spring arranged on the outside of the connecting rod member. Although this solution can lock a single operating lever to avoid accidental touch and improve the overall stability of the control valve operation process, it is not convenient to disassemble and repair a single oil circuit. Since this solution adopts an integrated design concept, all valve cores, valve bodies and other components are integrated into an integrated valve body. Its advantages are compact overall structure and few leakage points, and its disadvantage is that maintenance is relatively difficult.

[0005] Most multi-way hydraulic oil distributors have a bad working environment, especially the oil circuit inside the oil distributor is kept in a high-pressure environment for a long time. After working for a long time, the wear between the internal parts can easily lead to blockage of the oil circuit. This phenomenon cannot be completely avoided even if a filter device is installed upstream of the oil circuit. Therefore, it is necessary to regularly inspect and dredge the oil circuit inside the oil distributor. When one of the oil circuits is blocked or has other faults, the valve body needs to be disassembled as a whole, which not only consumes more manpower and material resources, but also the non-faulty oil circuit cannot work normally during the inspection and maintenance process, so it needs to be improved. Summary of the invention

[0016] Beneficial effects of the present invention: 1. When the present invention is working normally, oil flows in through the oil inlet and flows through the main oil tank to multiple sub-oil tanks. During this period, the oil flows through the circular grooves on multiple piston tubes, then enters the shell through the circular hole, and flows out through the oil outlet pipe connected to the top of the shell, thereby realizing multi-path control. When one of the oil circuits needs to be cleaned and maintained, the piston tube and the shell are pushed to move horizontally until one end of the shell slides out of the cavity. At this time, the piston tube is separated from the main oil tank, which does not affect the flow of oil, thereby ensuring the normal operation of the remaining oil circuits. In addition, one end of the piston tube is moved out of the cavity to seal it to prevent oil leakage, so that a single oil circuit can be quickly disassembled and repaired without affecting the normal operation of the remaining oil circuits.

[0017] 2. After the present invention moves one end of the shell out of the valve body, the long rod is reciprocated to move horizontally in the shell, driving the scraper to move horizontally toward the circular hole, scraping off the obstruction in the shell and pushing it toward the circular hole, and then sweeping it out with the help of a brush or other tools to complete the cleaning. When the shell needs to be disassembled for inspection, the long rod is pushed to insert the block into the square groove. At this time, the long rod is coaxially connected with the screw rod, and then the turntable is turned to make the screw rod rotate relative to the shell. At this time, the piston rod cannot rotate due to the fixed sliding rod, so that the screw rod is separated from the piston rod, and the shell is removed from the valve body for further maintenance and cleaning.

[0034] like Figures 1 to 10 As shown: A multi-way hydraulic oil distributor and a control method thereof, comprising a valve body 1, a plurality of oil circuit control mechanisms 2, wherein a main oil tank 10 and a plurality of oil sub-tanks 11 are provided inside the valve body 1, one end of the main oil tank 10 is communicated with an oil inlet 12 of the valve body 1, one end of the oil sub-tank 11 is communicated with the main oil tank 10, a plurality of cavities 13 are provided at one end of the valve body 1, the cavity 13 is located on a side of the oil sub-tank 11 away from the oil inlet 12 of the valve body 1, the cavity 13 passes through the main oil tank 10 and is communicated with it, the other end of the oil sub-tank 11 is communicated with the cavity 13, the oil circuit control mechanism 2 comprises a housing 20, a piston tube 21, a first spring 22, a quick-release cleaning assembly 3 and a fixed switch assembly 4, the housing One end of 20 is a tubular structure and is plugged into the cavity 13. The shell 20 and the piston tube 21 are detachably connected through a quick-release cleaning component 3. The outer periphery of the piston tube 21 is slidably connected to the inner wall of the cavity 13 and fits each other. One end of the first spring 22 is fixedly connected to the piston tube 21, and the other end of the first spring 22 is fixedly connected to the inner wall of the cavity 13. A through circular hole 200 is provided on the inner wall of one side of the shell 20, and the circular hole 200 is connected to the oil distribution groove 11. A through circular groove 210 is provided on one side of the piston tube 21, and the circular groove 210 is connected to the main oil groove 10. The fixed switch component 4 is used to fix the oil circuit control mechanism 2 and the switch that controls the oil circuit.

[0035] During normal operation, the oil flows in through the oil inlet 12 and flows through the main oil tank 10 to the multiple oil sub-tanks 11. During this period, the oil flows through the circular grooves 210 on the multiple piston tubes 21, then enters the housing 20 through the circular hole 200, and flows out through the oil outlet pipe 201 connected to the top of the housing 20, realizing multi-way control. When one of the oil circuits needs to be cleaned and maintained, the fixed switch assembly 4 is unlocked. At this time, the first spring 22 is in a compressed state. With the rebound of the first spring 22, the piston tube 21 and the housing 20 are pushed to move horizontally until one end of the housing 20 slides out of the cavity 13. At this time, the piston tube 21 is separated from the main oil tank 10, which does not affect the flow of oil, thereby ensuring the normal operation of the remaining oil circuits, and one end of the piston tube 21 is moved out of the cavity 13 to seal it to prevent oil leakage. Then, the oil circuit in the housing 20 is cleaned and maintained by the quick-release cleaning assembly 3, so that a single oil circuit can be quickly disassembled and repaired without affecting the normal operation of the remaining oil circuits.

[0036] like Figures 1 to 7 As shown: The quick-release cleaning assembly 3 includes a long rod 30, a rotating sleeve 31, a scraper 32 and a tension spring 33. The rotating sleeve 31 passes through the inner wall of the other end of the shell 20 and is rotatably connected thereto. A pair of protruding rods 300 and a pair of protrusions 301 are fixedly connected to the periphery of the long rod 30. Both the long rod 30 and the protruding rod 300 pass through the rotating sleeve 31 and the scraper 32 and are slidably connected thereto. The protrusion 301 is snap-fitted with the inner wall of the scraper 32. The periphery of the scraper 32 fits against the inner wall of the shell 20. The tension spring 33 is sleeved on the periphery of the long rod 30. One end of the tension spring 33 is fixedly connected to the rotating sleeve 31, and the other end of the tension spring 33 is fixedly connected to the scraper 32.

[0037] The quick-release cleaning assembly 3 also includes a screw 34, a block 35 and a turntable 36. One end of the screw 34 passes through the side wall of the shell 20 and is rotatably connected thereto, the other end of the screw 34 is threadedly connected to the piston rod, the block 35 is fixedly connected to one end of the long rod 30, the turntable 36 is coaxially connected to the other end of the long rod 30, and a square groove 340 is opened at one end of the screw 34, and the square groove 340 is plugged into the block 35.

[0038] A pair of slide bars 211 are fixedly connected to the periphery of the piston tube 21 , and a pair of slide grooves 130 are formed on the inner wall of the cavity 13 , and the slide grooves 130 are slidably connected to the slide bars 211 .

[0039] After one end of the shell 20 is moved out of the valve body 1, the long rod 30 is pulled back and forth to move horizontally in the shell 20. When the long rod 30 moves to one end of the shell 20, the protrusion 301 on the long rod 30 is stuck in the inner wall of the scraper 32. Then the long rod 30 continues to move, driving the scraper 32 to move toward the circular hole 200, and scrapes off the obstruction in the shell 20 and pushes it toward the circular hole 200, and sweeps it out with the help of a brush or other tools to complete the cleaning. When the long rod 30 moves to the other end of the shell 20, as the scraper 32 translates, the tension spring 33 is gradually stretched, so that the tension on the scraper 32 gradually increases. When the scraper 32 moves to the circular hole 200, the tension is greater than the friction between the protrusion 301 and the scraper 32, so that the scraper 32 is separated from the protrusion 301, and the tension spring 33 rebounds to drive the scraper 32 to reset. Then the turntable 36 is rotated to make the protrusion 300 on the long rod 30 drive the rotating sleeve 31 and the scraper 32 to rotate, so that the scraper 32 rotates relative to the shell 20, thereby adjusting the angle of the scraper 32 to clean up obstructions at different positions. The scraper 32 is composed of two fan-shaped plates that are symmetrical up and down, which can prevent the oil from flowing back due to negative pressure during cleaning. When the housing 20 needs to be disassembled for inspection, the long rod 30 is pushed to insert the block 35 into the square groove 340. At this time, the long rod 30 is coaxially connected with the screw rod 34. Then, the turntable 36 is turned to make the screw rod 34 rotate relative to the housing 20. At this time, the piston rod is fixed by the sliding rod 211 and cannot rotate, so that the screw rod 34 is separated from the piston rod, and the housing 20 is removed from the valve body 1 for further maintenance and cleaning.

[0040] like Figures 1 to 10As shown: The fixed switch assembly 4 includes a rotating seat 40, a grip 41, a contact 410, a contact block 42, a vertical rod 420, a piston plate 43 and a second spring 44. The bottom of the rotating seat 40 is rotatably connected to the top of the housing 20. The oil circuit inside the housing 20 is a T-shaped structure. One side of the top of the housing 20 is connected to an oil outlet pipe 201. An empty groove 400 is opened on the top of the rotating seat 40. The middle part of the contact 410 is rotatably connected to the inner wall of the empty groove 400. One end of the contact 410 is fixedly connected to the grip 41, and the other end of the contact 410 is an arc-shaped protruding structure. The contact block 42 is slidably connected to the inner wall of the empty groove 400, the top of the contact block 42 is an arc-shaped concave structure and contacts the outer periphery of the contact 410, the top of the vertical rod 420 is fixedly connected to the bottom of the contact block 42, the vertical rod 420 passes through the bottom wall of the empty groove 400 and is slidably connected thereto, the bottom of the vertical rod 420 is coaxially connected to the top of the piston plate 43, the piston plate 43 is located at the bottom of the oil outlet pipe 201 and is slidably connected to the top inner wall of the shell 20, and the second spring 44 is installed on the rotating seat 40, and the second spring 44 is used to provide thrust to the contact block 42.

[0041] The second spring 44 is sleeved on the outer periphery of the vertical rod 420 , one end of the second spring 44 is fixedly connected to the bottom wall of the slot 400 , and the other end of the second spring 44 is fixedly connected to the outer periphery of the vertical rod 420 .

[0042] The fixed switch assembly 4 also includes a toothed ring 45, a rack 46, a slide rail 47 and a limit plate 48. The toothed ring 45 is fixedly connected to the periphery of the rotating seat 40, the toothed ring 45 and the rack 46 are meshed with each other, the slide rail 47 is fixedly connected to one end of the top of the shell 20 close to the valve body 1, the bottom of the rack 46 is slidably connected to the inner wall of the slide rail 47, one end of the limit plate 48 is fixedly connected to the top of the valve body 1, one side of the rack 46 is plugged into and matched with the socket 480 on the limit plate 48, a plurality of limit rods 202 are fixedly connected at the four corners of one end of the shell 20, a plurality of limit holes 14 are opened at one end of the valve body 1, and the limit holes 14 are plugged into and matched with one end of the limit rod 202.

[0043] The fixed switch assembly 4 also includes a protrusion 49, which is fixedly connected to the top inner wall of the shell 20. An L-shaped groove 430 is opened on the periphery of the piston plate 43, and the L-shaped groove 430 is slidably connected to the protrusion 49. When the protrusion 49 is located at one end of the L-shaped groove 430, the vertical rod 420 can slide up and down to control the switch of the oil circuit. When the protrusion 49 is located at the other end of the L-shaped groove 430, the vertical rod 420 cannot move up and down, and the oil circuit remains closed.

[0044] When the oil circuit control mechanism 2 is in working state and the oil circuit is unblocked, the handle 41 is in a vertical state, at which time the protruding end of the contact 410 is located at its bottom and contacts the top of the contact block 42, so that the vertical rod 420 is pushed, driving the piston plate 43 to move downward to the bottom of the housing 20, and the protrusion 49 slides upward out of the L-shaped groove 430, so that the T-shaped oil circuit in the housing 20 is unblocked, and at the same time the second spring 44 is compressed, generating an upward thrust, and the friction force between the contact block 42 and the contact 410 that contacts the handle 41 is in contact with each other keeps the handle 41 in a vertical state, ensuring that the oil circuit is not easily closed accidentally. When the oil circuit needs to be unblocked, press the handle to rotate it to a horizontal state, at which time the protruding end of the contact 410 rotates to a horizontal state, the space between the contact 410 and the contact block 42 increases, the second spring 44 rebounds and pushes the vertical rod 420 upward, the piston plate 43 slides upward into the top of the housing 20 and fits the inner wall of the housing 20, and the protrusion 49 slides into the L-shaped groove 430 to close the oil circuit. Then, the handle is rotated 90 degrees clockwise to rotate the rotating seat 40 on the top of the housing 20, driving the toothless ring 45 to rotate, and through the meshing transmission between the toothless ring 45 and the rack 46, the rack 46 slides horizontally along the slide rail 47 and separates from the insertion hole 480 on the limit plate 48, thereby releasing the lock of the housing 20, and the first spring 22 rebounds to push the housing 20 out of the cavity 13, which is convenient for cleaning and maintenance.
