Valve remote control device, tank and tank container

Abstract

The application provides a valve remote control operating device, a tank body and a tank container. When the operating handle is rotated, the operating handle drives the rotating shaft to rotate, and the rotating shaft drives the shifting rod to rotate clockwise or counterclockwise. When the shifting rod rotates, the linkage at the end of the shifting rod moves in the opening direction of the slot in the clamping groove, and the sliding piece moves in the sliding rail. The rotating action of the linkage driven by the rotating shaft is decomposed into the movement of the linkage in the clamping groove of the sliding piece and the movement of the sliding piece in the extension direction of the sliding rail. Since the opening direction of the slot of the clamping groove is perpendicular to the extension direction of the sliding rail, the sliding piece will not produce oblique swing, and the connecting piece connected to the sliding piece will not produce oblique swing, but will move in the extension direction of the sliding rail along the sliding piece, avoiding the generation of additional resistance of the connecting piece in the driving process, eliminating the influence of the swing displacement of the shifting rod on the connecting piece when the shifting rod rotates, and ensuring the normal service life of the connecting piece, thereby ensuring the normal opening and closing of the valve.

DETAILED DESCRIPTION

[0021] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can be varied in a wide range of embodiments, none of which depart from the scope of the present application, and that the description and drawings are to be considered as illustrative in nature, and not as restrictive to the present application.

[0022] In order to further illustrate the principles and structures of the present application, the preferred embodiments of the present application will be described in detail in conjunction with the accompanying drawings.

[0023] Referring to Figures 1 to 3 An embodiment of the present application provides a valve remote control operating device 100, which is mainly applied to a tank container, and is used for opening and closing the valve on the tank container.

[0024] In the embodiment, the valve remote control operating device 100 includes an operating box and a connecting piece 50. The operating box includes a box body 10, a rotating shaft 20, a linkage assembly 30, and a sliding assembly 40.

[0025] Specifically, the rotating shaft 20 is rotatably arranged on the surface inside the box body 10, and the rotation axis of the rotating shaft 20 is perpendicular to the surface of the box body 10. The linkage assembly 30 includes a push rod 31 and a linkage 32. One end of the push rod 31 is connected with the rotating shaft 20 to rotate with the rotating shaft 20, and the linkage 32 is arranged at the other end of the push rod 31. The sliding assembly 40 includes a sliding rail 42 fixed on the box body 10 and a sliding piece 43 movably arranged on the sliding rail 42. The sliding piece 43 is provided with a clamping groove 41, and the opening direction of the clamping groove 41 is perpendicular to the extension direction of the sliding rail 42. The linkage 32 is clamped in the clamping groove 41 and can move along the opening direction of the clamping groove 41.

[0026] One end of the connecting piece 50 is connected with the sliding piece 43, and the other end is used for connecting with the valve. In the embodiment, the connecting piece 50 can be a flexible structure for realizing push-pull, such as a flexible shaft, etc., and can also be a rigid structure, such as a connecting rod, a rigid shaft, etc.

[0027] The rotating shaft 20 rotates the push rod 31, so that the linkage 32 moves in the clamping groove 41, and the sliding piece 43 moves along the slide rail 42, thereby driving the connecting piece 50 to open or close the valve.

[0028] Further, the operation box of the embodiment further comprises an operation handle 60. The operation handle 60 is fixed with the rotating shaft 20 to control the rotation of the rotating shaft 20.

[0029] In the embodiment, one end of the operation handle 60 is fixed with the rotating shaft 20, and the other end extends outward beyond the top of the box body 10. By arranging the operation handle 60, the rotation of the rotating shaft 20 can be conveniently controlled by the staff, so that the effective control of the entire valve remote control operation device 100 can be realized.

[0030] One end of the push rod 31 is fixed on the rotating shaft 20, and the other end is provided with the linkage 32. In the embodiment, the linkage 32 is protruded on the surface of the push rod 31, and the protruding direction of the linkage 32 is towards the surface of the box body 10. The protrusion of the linkage 32 can facilitate the clamping of the linkage 32 and the sliding piece 43 in the clamping groove 41 on the surface of the box body 10, effectively realize linkage control, and facilitate the following of the sliding piece 43 to the rotation of the rotating shaft 20.

[0031] The linkage 32 of the embodiment can be a pin shaft, a screw or the like fastener. The linkage 32 can be integrally formed with the push rod 31, or can be detachably connected with the push rod 31.

[0032] Further, the linkage 32 is clamped in the clamping groove 41 of the sliding piece 43 in the sliding assembly 40. In the embodiment, the sliding assembly 40 is arranged below the rotating shaft 20 as a whole.

[0033] The sliding assembly 40 comprises a slide rail 42 and a sliding piece 43 slidably arranged on the slide rail 42. The extending direction of the slide rail 42 is parallel to the surface of the box body 10. The clamping groove 41 is arranged on the sliding piece 43, and the opening direction of the slot of the clamping groove 41 is perpendicular to the extending direction of the slide rail 42.

[0034] In the embodiment, the slide rail 42 extends in the horizontal direction, and the slot of the clamping groove 41 is arranged in the vertical direction, so that the opening direction of the slot of the clamping groove 41 is perpendicular to the extending direction of the slide rail 42.

[0035] The horizontal extension of the slide rail 42 and the vertical arrangement of the slot of the clamping groove 41 can facilitate the arrangement of the slide rail 42 on the box body 10, and the arrangement of the structure of the sliding piece 43 itself facilitates the cooperation of the linkage 32 and the clamping groove 41 on the sliding piece 43, thereby facilitating the driving of the sliding piece 43 by the push rod 31.

[0036] In the embodiment, the sliding member 43 comprises a connecting portion 431 and a pulley 432. The connecting portion 431 is fixed with the connecting member 50, and a clamping groove 41 is formed on the connecting portion 431 and vertically arranged on the connecting portion 431. The pulley 432 is arranged on the connecting portion 431 and slidably arranged in the slide rail 42 to drive the connecting portion 431 to slide along the slide rail 42. In addition, the pulley 432 can be arranged to roll in the slide rail 42 according to requirements.

[0037] In the embodiment, the clamping groove 41 penetrates the connecting portion 431 along the thickness direction of the connecting portion 431, and the pulley 432 is arranged in pairs and arranged on both sides of the clamping groove 41. The arrangement of the pulley 432 in pairs can ensure the stability of the sliding member 43 sliding in the slide rail 42, ensure the stable force transmission between the lever 31 and the sliding assembly 40, and thus ensure the stable driving of the connecting member 50 by the eastern part.

[0038] In the embodiment, one end of the connecting member 50 is connected to the connecting portion 431 of the sliding member 43, and the other end of the connecting member 50 penetrates the box body 10 and is used to be connected with the valve rod of the valve. When the pulley 432 moves along the slide rail 42, the connecting portion 431 can drive the connecting member 50 to move in the horizontal direction, the connecting member 50 pulls the valve rod of the valve fixed thereto to drive the corresponding valve rod to rotate, so as to open or close the valve.

[0039] When the operating handle 60 is rotated, the operating handle 60 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the lever 31 to rotate clockwise or counterclockwise. When the lever 31 rotates, the linkage 32 at the end of the lever 31 moves in the vertical direction in the clamping groove 41 of the sliding member 43, and the sliding member 43 moves in the horizontal direction in the slide rail 42, that is, the rotating action of the linkage 32 driven by the rotating shaft 20 is decomposed into the movement of the linkage 32 in the clamping groove 41 of the sliding member 43 and the movement of the sliding member 43 in the extension direction of the slide rail 42. Since the opening direction of the clamping groove 41 is perpendicular to the extension direction of the slide rail 42, the sliding member 43 will not produce oblique swing, and the connecting member 50 connected to the sliding member 43 will also not produce oblique swing, but will move in the extension direction of the slide rail 42 along the sliding member 43, avoiding the generation of additional resistance of the connecting member 50 in the driving process, eliminating the influence of the swing displacement of the lever 31 on the connecting member 50 when the lever 31 rotates, ensuring the normal service life of the connecting member 50 and ensuring the normal opening and closing of the valve.

[0040] The application also provides a tank body provided with a valve and the valve remote control operating device 100. The connecting member 50 of the valve remote control operating device 100 is connected and fixed with the valve rod of the valve.

[0041] In the embodiment, the valve can be a gas phase valve which is arranged at the top of the tank body. The connecting member 50 is connected and fixed with the valve rod of the gas phase valve. When it is needed to open or close the gas phase valve, it can be realized by rotating the operating handle 60.

[0042] In addition, the application further provides a tank container which comprises a frame and the tank body as described above, and the tank body is supported by the frame.

[0043] For the valve remote control operating device, the tank body and the tank container of the application, when the operating handle is rotated, the operating handle drives the rotating shaft to rotate, and the rotating shaft drives the shifting rod to rotate clockwise or counterclockwise. When the shifting rod rotates, the linkage member at the end of the shifting rod moves in the opening direction of the slot of the clamping groove of the sliding member, and the sliding member moves in the sliding rail, that is, the rotating action of the linkage member driven by the rotating shaft is decomposed into the movement of the linkage member in the clamping groove of the sliding member and the movement of the sliding member in the extending direction of the sliding rail, and since the opening direction of the slot of the clamping groove is perpendicular to the extending direction of the sliding rail, the sliding member will not produce oblique swing, and the connecting member connected to the sliding member will not also produce oblique swing, but will only move in the extending direction of the sliding rail along with the sliding member, avoiding the generation of additional resistance of the connecting member in the driving process, eliminating the influence of the swing displacement of the shifting rod when rotating on the connecting member, and ensuring the normal service life of the connecting member, thereby ensuring the normal opening and closing of the valve.
