Technical Field
[0001] This application relates to the field of manual valve control technology, specifically to a robotic manual valve control device. Background Technology
[0002] In industrial automation control systems, valve opening and closing control is crucial, especially in pipeline systems requiring precise control of fluid or gas flow. Traditional valve control devices typically rely on manual operation or mechanical transmission, which often suffer from low efficiency, cumbersome operation, and susceptibility to human error. Therefore, with the development of automation technology, more and more intelligent control devices are being applied to valve control to improve work efficiency and reduce human error.
[0003] However, existing valve control devices lack a convenient and reliable manual control method when the electrical control system malfunctions or manual intervention is required, and often cannot achieve seamless switching between electrical and manual control. Furthermore, existing mechanical transmission systems are prone to operational instability due to insufficient friction during valve control, affecting the valve's opening and closing performance.
[0004] Therefore, developing a valve control device that can flexibly switch between electronic and manual control, is easy to operate, and has high-efficiency driving performance has become a requirement for improving industrial automation and work efficiency. Summary of the Invention
[0005] To address the aforementioned technical problems, this application solves the problem of flexible automatic and manual control of valves in the prior art.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] like Figures 1 to 6 As shown, a robotic arm valve control device includes a valve 101, a housing 103 fixedly mounted on the valve 101, a valve handle 102 rotatably mounted on the valve 101, a retainer 104 and a limiting rod 106 slidably mounted on the valve handle 102, the retainer 104 and the limiting rod 106 being fixedly connected, a lower engagement disc 105 fixedly mounted on the retainer 104, the lower engagement disc 105 having annularly arranged teeth, a mounting plate 109 fixedly mounted on the housing 103, a main shaft 110 slidably mounted on the mounting plate 109, the main shaft 110 being a telescopic structure that slides vertically relative to each other, an upper engagement disc 111 fixedly mounted at one end of the main shaft 110 near the valve handle 102, the upper engagement disc 111 having annularly arranged teeth at one end of the upper engagement disc 111 near the lower engagement disc 105, the teeth on the lower engagement disc 105 engaging with the teeth on the upper engagement disc 111.
[0029] Specifically, such as Figure 3 and Figure 4 As shown, the card holder 104 is provided with two limiting rods 106, and there is a gap between the limiting rods 106 and the card holder 104. This gap is used to insert the valve handle 102. The side of the card holder 104 is provided with a downwardly extending convex plate. The convex plate contacts the outer edge of the valve handle 102, thereby using the convex plate to push the valve handle 102 to rotate on the valve 101, thereby realizing the control of the robotic valve.
[0030] Before use, insert the retainer 104 horizontally onto the valve handle 102, so that the end of the valve handle 102 that contacts the valve 101 is located between the retainer 104 and the limiting rod 106. The two limiting rods 106 and the protruding plate on the side of the retainer 104 form a restraint, preventing the retainer 104 from disengaging from the valve handle 102 when the retainer 104 and the valve handle 102 are rotated. The outer casing 103 is installed on the pipeline of the valve 101 by bolts, snap rings, and other structures.
[0031] Figures 1 to 6 The shown state indicates that the upper engagement disc 111 is disengaged from the retaining seat 104. In this state, the upper engagement disc 111 cannot drive the retaining seat 104 to rotate, and therefore cannot control the rotation of the valve handle 102. This state is used when the electronic control system fails and manual intervention is required or more convenient, allowing the operator to manually disengage the upper engagement disc 111 from the retaining seat 104. Figure 5 and Figure 6 In the indicated state, the valve handle 102 is manually controlled to rotate on the valve 101. When electrical control is required, the upper engagement disc 111 is controlled to make close contact with the seat 104, so that the upper engagement disc 111 is controlled to rotate when needed. Then, through the engagement relationship, the upper engagement disc 111 drives the seat 104, so that the valve handle 102 rotates on the valve 101.
[0032] like Figure 5 and Figure 6 As shown, a spring 112 is sleeved on the main shaft 110. One end of the spring 112 near the upper meshing disk 111 is fixedly connected to the upper meshing disk 111, and the other end of the spring 112 away from the upper meshing disk 111 is slidably connected to the main shaft 110.
[0033] like Figure 5 and Figure 6 As shown, a push-pull rod 113 is fixedly installed at one end of the spring 112 away from the upper engagement plate 111. Two vertical slide rods are provided on the push-pull rod 113, and the vertical slide rods slide on the slide groove of the mounting plate 109.
[0034] like Figure 5 and Figure 6As shown, the mounting plate 109 is provided with two rotating shafts, each of which is rotatably provided with a control rod 114 and a torsion spring. The end of the control rod 114 near the push-pull rod 113 is provided with a sliding groove, and a convex shaft is fixedly provided on the push-pull rod 113. The convex shaft slides on the sliding groove of the control rod 114.
[0035] Specifically, when it is necessary to control the upper engagement disc 111 to disengage from the card holder 104, and when it is not possible to use an electronic control system or when manual operation is more convenient, the control lever 114 is manually controlled to rotate on the shaft of the mounting plate 109, and the torsion spring on the shaft is twisted. This causes the sliding groove of the control lever 114 to drive the convex shaft of the push-pull rod 113, thereby controlling the push-pull rod 113 to slide vertically on the vertical sliding groove of the mounting plate 109. That is, the control lever 114 rotates clockwise, and the sliding groove of the control lever 114 causes the push-pull rod 113 to move vertically upward. This causes the push-pull rod 113 to pull the upper end of the spring 112, and the elastic force of the spring 112 pulls the upper engagement disc 111 to disengage from the card holder 104. When the upper engagement disc 111 moves upward, it also pushes the lower part of the telescopic structure of the main shaft 110 to slide on the upper part, thus achieving retraction.
[0036] like Figure 5 As shown, when the upper engagement disc 111 disengages from the holder 104, the control lever 114 rotates clockwise to a horizontal position. At this time, the operator can control the valve handle 102 to rotate on the valve 101. When rotating, the valve handle 102 actively drives the holder 104 to rotate. After the operator completes the control of the robotic arm valve, i.e., the valve handle 102, they release the control lever 114. Under the action of the torsion spring on the rotating shaft of the mounting plate 109, the control lever 114 rotates counterclockwise. The needle rotates, thus changing from a horizontal state to an inclined state. That is, the end of the control lever 114 away from the push-pull rod 113 moves upward and closer to the outer casing 103. Under the action of gravity of the upper engagement plate 111, the main shaft 110, the spring 112 and the push-pull rod 113, the lower part of the telescopic structure of the upper engagement plate 111 and the spring 112 moves downward and closer to the lower engagement plate 105. The teeth on the upper engagement plate 111 mesh with the teeth on the lower engagement plate 105. The spring 112 drives the push-pull rod 113 to return to its original position. Because of the torsion spring on the shaft of the mounting plate 109, the control lever 114 will maintain a counterclockwise rotation trend. As a result, the slide groove at the left end of the control lever 114 will continuously push the push-pull rod 113 downward, causing the push-pull rod 113 to continuously push the upper end of the spring 112, compressing the spring 112 to a certain extent. This makes the engagement between the upper meshing plate 111 and the lower meshing plate 105 tighter, increasing the friction between the upper meshing plate 111 and the lower meshing plate 105. This prevents the lower meshing plate 105 from disengaging from the upper meshing plate 111 due to insufficient friction when the upper meshing plate 111 actively controls the rotation of the lower meshing plate 105 and the valve handle 102.
[0037] like Figure 5 and Figure 6 As shown, the ends of the two control levers 114 furthest from the push-pull rod 113 are connected by a crossbar for synchronously controlling the rotation of the two control levers 114. Specifically, the operator manually controls the crossbar between the two control levers 114, thereby causing the control levers 114 on both sides of the mounting plate 109 to rotate synchronously, jointly controlling both ends of the push-pull rod 113, achieving balanced movement of the spring 112, and thus making the lifting of 12 smoother.
[0038] like Figure 5 As shown, a motor 107 is fixedly installed on the housing 103, and the input end of a universal transmission 108 is fixedly connected to the output shaft of the motor 107. The universal transmission 108 is fixedly installed on the housing 103, and the output end of the universal transmission 108 is fixedly connected to the end of the main shaft 110 away from the upper meshing plate 111.
[0039] Specifically, an electronic control board is installed inside the outer casing 103, and an electronic control system is installed on the electronic control board. In the initial state, the control lever 114 is in an inclined state after being rotated counterclockwise, so that the upper meshing disc 111 and the lower meshing disc 105 are tightly engaged. During operation, through the electronic control system, the operator can remotely control the start of the motor 107, so that the operator can control the conveying capacity of each pipeline in real time according to the data of each process of the project, that is, control the opening and closing of the robotic arm valve and the degree of opening and closing.
[0040] In use, the electronic control system starts the motor 107. The power of the motor 107 drives the upper part of the main shaft 110 to rotate on the mounting plate 109 through the universal transmission 108. Thus, the upper part of the main shaft 110 drives the lower part of the main shaft 110, which in turn drives the upper meshing disc 111. The upper meshing disc 111 drives the lower meshing disc 105 and the card holder 104 through the meshing relationship. The card holder 104 drives the valve handle 102 to rotate on the valve 101 through the side protrusion and the limit rod 106, thereby realizing the opening and closing control of the valve 101.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
