Description

Technical Field

[0001] The utility model relates to the technical field of fluid transmission and distribution, in particular to an improved structure of a hydraulic transmission distributor, which performs operations of different valves for fluid transmission to achieve a stable and reliable precise control effect. Background Art

[0002] In many processing equipment, gas or liquid (such as air, water, oil) is usually distributed to a mechanical component at high pressure or high temperature to produce interaction or restore existing functions. Furthermore, it is edited into a set of cycle modes in chronological order to produce an automated control system to achieve the goals of simplifying control, saving costs and increasing production capacity.

[0003] Based on the advantages of reliability, safety and stepless speed regulation, fluid control technology is widely used in automated processing equipment and applied in the supply of raw materials and materials. The compression volume of oil is very small and is considered incompressible under normal pressure. Therefore, the hydraulic transmission device relies on the flow of oil in the pipeline with hydraulic buffer device to smoothly transmit power, unlike mechanical transmission that suffers from vibration or impact due to processing and assembly errors, which helps to achieve energy conversion.

[0004] During oil circuit switching or steering movement, traditional hydraulic transmission devices use solenoid valves to control the fluid pressure of the pipeline. However, each solenoid valve must have a reliable operating level to allow the hydraulic transmission device to operate normally. Once more control items are implemented, the construction cost of the entire set of equipment is bound to increase, which consumes more inspection time and maintenance costs. Utility Model Content

[0005] In view of this, the applicant in this case provided an improved structure of the hydraulic transmission distributor, the purpose of which is: in addition to manually operating the hydraulic transmission, a variety of control methods are used to enable the hydraulic transmission to have an automatic adjustment function, which can control the hydraulic oil to flow through different oil outlets and then flow into multiple valves through pipelines, accurately execute the distribution of liquid pressure, and enable the fluid pipeline to smoothly transmit energy.

[0006] In order to achieve the above object, the utility model includes:

[0007] A distributor, comprising: a partition plate, which divides the interior of the distributor into a first compartment and a second compartment; at least one oil inlet hole, which is connected to the first compartment; at least one oil return hole, which is connected to the second compartment; a plurality of oil outlet holes, which are respectively formed on the partition plate, and the oil outlet holes connect the first compartment with the periphery of the partition plate; a plurality of oil inlet holes, which are respectively formed on the partition plate, and the oil inlet holes connect the second compartment to the periphery of the partition plate;

[0008] A diverter plate is placed in the first compartment and is rotatable. A plurality of diverter holes are provided on the diverter plate so that two surfaces of the diverter plate are connected. The diverter plate blocks the first compartment and the oil outlet hole. When the diverter plate rotates at an angle, the diverter holes connect the oil outlet hole with the oil inlet hole.

[0009] An automatic drive assembly, which is connected to the diverter plate to rotate;

[0010] A pipeline configured with a distributed control system to output a signal; and

[0011] A control circuit receives the signal and operates the automatic drive assembly to control the diverter plate to divert the hydraulic oil to the pipeline.

[0012] Furthermore, it also includes a manual drive component, which is transmission-connected to the diverter plate.

[0013] Furthermore, it also includes a marking plate, which is installed outside the distributor. The marking plate has multiple marks for judging the rotation direction, angle and residence time of the diverter plate.

[0014] Furthermore, each oil outlet hole is connected to the pipeline, and the other end of the pipeline is connected to a plurality of valves.

[0015] After adopting the above scheme, the utility model achieves the following effects:

[0016] 1. Automated hydraulic transmission: The distributed control system outputs a signal to the control circuit, which is electrically connected and operates the automatic drive component to drive the diverter plate to rotate, so that the diverter plate accurately controls the inlet and outlet of the hydraulic oil of the distributor, so that the hydraulic oil in the first compartment flows into the pipeline through the oil outlet hole in sequence, thereby allowing the hydraulic transmission to have an automatic adjustment function, achieving accurate liquid pressure distribution, and allowing the fluid pipeline to transmit energy smoothly.

[0018] 3. Indicator plate and marking: The indicator plate and its marking can help determine the rotation direction, angle and residence time of the diverter plate, so as to understand the action status of the distributor regarding the hydraulic transmission, allowing on-site operators to effectively understand the valve actuation status and position.

[0019] 4. Multi-valve control: The hydraulic oil from each oil outlet reaches different valves through pipelines to perform the switching actions of different valves, so that the system can realize multiple functions and quickly execute the switching actions of each valve.

DETAILED DESCRIPTION

[0028] Figure 1 , Figure 3 , Figure 4 In the first embodiment of the utility model, a first shell cover 11 and a second shell cover 12 are mounted on both sides of a partition plate 13. A first compartment 101 is the interior of the first shell cover 11, which is closed by the partition plate 13 and can be connected to the outside through an oil inlet hole 111 of the first shell cover 11. A second compartment 102 is the interior of the second shell cover 12, which is closed by the partition plate 13 and can be connected to the outside through an oil return hole 121 of the second shell cover 12. When the second shell cover 12 locks an object such as a machine, equipment or pipeline, the distributor 10 is stationary.

[0029] The separation plate 13 is combined between the first shell cover 11 and the second shell cover 12 by riveting or screwing. The separation plate 13 has a plurality of oil outlet holes 131 and a plurality of oil inlet holes 132. One end of the oil outlet hole 131 leads to the first compartment 101, and the other end is connected to the outside through the circumferential surface of the separation plate 13. One end of the oil inlet hole 132 leads to the second compartment 102, and the other end is connected to the outside through the circumferential surface of the separation plate 13. The oil inlet hole 132 and the oil outlet hole 131 are staggered.

[0030] The distributor 10 has a diverter plate 20, which forms a plurality of diverter holes 21, and the diverter holes 21 are connected to two plate surfaces of the diverter plate 20. The diverter plate 20 is sealed in the first compartment 101 by the separation plate 13.

[0031] The distributor 10 also has a shaft 22, one end of which is connected to the center of the diverter plate 20, and the other end passes through the partition plate 13 and the second compartment 102, extends out of the second shell cover 12 and is connected to a marking plate 50. The shaft 22 rotates relative to the distributor 10, and the diverter plate 20 blocks the oil outlet 131 and the first compartment 101. The shaft 22 drives the diverter plate 20 to rotate to an angle and stay for a predetermined time, and the oil outlet 131 is connected to the first compartment 101 through the diverter hole 21, so that the oil outlet 131 to the oil inlet 111 remains unobstructed.

[0032] Assuming that the diameter of the diverter hole 21 is larger than the inlet of the oil inlet hole 111, the hydraulic oil introduced from the outside by the oil inlet hole 111 can quickly pass through the oil outlet hole 131 and reach a valve 53 via a pipeline 46 (see Figure 6 ), making its switch (ON / OFF) response faster.

[0033] Figure 2 In the figure, the marking plate 50 is provided with a plurality of marks (not shown), each of which helps to determine the rotation direction, angle and residence time of the diverter plate 20, so as to understand the action state of the distributor 10 with respect to the hydraulic transmission.

[0034] like Figure 1 , Figure 3 As shown, in this embodiment, the dispenser 10 can be selected to perform the function of hydraulic transmission through one of the manual mode and the automatic mode.

[0035] In manual mode, a manual drive assembly 60 is connected to the diverter plate 20. The manual drive assembly 60 has a lever 61 pivoted to the shaft 22, which drives a ratchet 23 of the shaft 22 to rotate, and the diverter plate 20 rotates in the same direction to a desired direction and angle. Two rockers 24 are arranged around the shaft 22, and the rockers 24 prevent the ratchet 23 from rotating.

[0036] In the automatic mode, a control circuit 40 is electrically connected to and operates an automatic drive assembly 30 to drive the diverter plate 20 to rotate. The automatic drive assembly 30 includes: an actuator 31 and a set of connecting rods 32, the set of connecting rods 32 connecting the ratchet 23 and an output shaft 311 of the actuator 31 along a linear motion. The actuator 31 can be a hydraulic cylinder or a pneumatic cylinder.

[0037] When the actuator 31 is a hydraulic cylinder, the hydraulic cylinder is connected to the pipeline 46 (see Figure 6 ) is an electromagnetic valve (not shown), which is electrically connected to the control circuit 40. According to actual needs, the control circuit 40 pre-sets a control mode, such as: the rotation sequence, rotation direction, rotation angle and residence time of the diverter plate 20. After starting, the control circuit 40 operates the automatic drive component 30 according to the preset value, so that the diverter plate 20 accurately controls the distributor 10, so that the hydraulic oil in the first compartment 101 flows into each of the oil outlet holes 131 in sequence and is transported to different valves 53 (see Figure 6 ).

[0038] When the actuator 31 is a pneumatic cylinder, the output shaft 311 of the pneumatic cylinder is connected to the ratchet 23 through the connecting rod 32, and can also push the ratchet 23 to rotate the shaft 22, and the diverter plate 20 is rotated in the same direction to the expected direction and angle. The pneumatic cylinder is used as an actuator, which is not only easy to clean the environment of the work site, but also less pollution and convenient for maintenance.

[0039] like Figure 5 As shown, the second embodiment of the diverter plate 20 has a structure substantially similar to that of the first embodiment, with the difference being the control mode of the control circuit 40 .

[0040] Specifically, the shaft 22 protrudes a plurality of short posts 25, each of which has a different rotation angle relative to the diverter plate 20. The control circuit 40 is electrically connected to a micro switch 41, and the micro switch 41 contacts the short posts 25 to generate a signal, such as a voltage. The control circuit 40 receives the signal and operates the diverter plate 20 to rotate to a corresponding angle, thereby accurately controlling the hydraulic fluid to flow into the correct oil outlet 131.

[0041] like Figure 1 , Figure 6As shown, in other control modes, the valve 53 is used to inform the control circuit 40 of the timing to operate the hydraulic cylinder (i.e., the actuator 31). The valve 53 has a three-way valve seat 54, and the valve seat 54 receives a valve plate 56 inside. The valve plate 56 is combined with a valve stem 55 extending out of the valve 53. A cylinder body 35 is fixed outside the valve 53, and a rod 36 inside the cylinder body 35 is connected to the valve stem 55. The cylinder body 35 has two oil passage holes: a first oil passage hole 37 and a second oil passage hole 38, which determine the telescopic movement of the rod 36.

[0042] The first oil passage hole 37 is connected to the oil outlet hole 131, and the hydraulic fluid is guided to push the rod 36 out of the cylinder body 35, so that the valve stem 55 moves in the direction of the arrow 57, and the valve plate 56 seals the valve seat 54, thereby achieving the tight fit of the valve 53. The second oil passage hole 38 is connected to the oil return hole 121, and the hydraulic fluid is guided to push the rod 36 into the cylinder body 35, so that the valve stem 55 and the valve plate 56 release the tight fit of the valve seat 54, allowing the gas or fluid to be transported to the predetermined position through the valve seat 54.

[0043] In this embodiment, the cylinder body 35 has a larger size, which relatively increases the pressure applied by the rod 36, allowing the valve plate 56 to press the valve seat 54 more tightly, so that the sealing and leak-proof effect of the valve 53 is better.

[0044] Secondly, the first oil passage hole 37 and the second oil passage hole 38 are connected to the oil return hole 121 and the oil outlet hole 131 via the pipeline 46. The pipeline 46 is equipped with a distributed control system 45 (DCS) to output a signal to the control circuit 40 to operate the distributor 10 to accurately control the inflow and outflow of hydraulic oil and execute the opening and closing of different valves 53.

[0045] The technical content and technical features of the present invention have been disclosed as above. The protection scope of the present invention is not limited to that disclosed in the embodiments, but includes various replacements and modifications that do not deviate from the present invention.
