[0001] The present invention relates to the technical field of tank containers, and in particular to a tank container, a tank body and a linkage control device. Background Art

[0002] When loading and unloading tank containers or other mobile or fixed containers, the air valve must be opened at the same time when the loading and unloading valve is opened to ensure the pressure balance in the container. In the actual operation process, the operator needs to open the air valve before opening the loading and unloading valve to ensure the smooth completion of the loading and unloading operation.

[0003] However, in the actual loading and unloading process, operators tend to forget to open the air valve before opening the loading and unloading valve. When the loading and unloading valve is opened but the gas phase valve is not opened, the internal air pressure of the tank body cannot reach a dynamic balance with the external air pressure, resulting in excessive internal pressure of the tank body and instability of the tank body, which affects the smooth progress of the loading and unloading operation.

DETAILED DESCRIPTION

[0020] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0021] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0022] The present application provides a linkage control device, which is mainly used in a tank container to regulate the opening and closing of a bottom valve and an air valve of the tank body.

[0023] See also Figures 1 to 3The linkage control device 1 includes a control member 11 and a limit assembly 12. The control member 11 can rotate relative to the tank body to switch between a closed state and an open state. The control member 11 is linked with the switch of the air valve 2 to control the opening and closing of the air valve 2, that is, when the control member 11 is in the open state, the switch of the air valve 2 is opened; when the control member 11 is in the closed state, the switch of the air valve 2 is closed.

[0024] The limiting assembly 12 includes a first limiting member 121 and a second limiting member 122. The first limiting member 121 is fixed on the operating member 11. The first limiting member 121 is provided with a slide groove 123. The slide groove 123 includes a first arc segment 1231 and a second arc segment 1232. The movable end of the second limiting member 122 is movably arranged in the slide groove 123, and the fixed end of the second limiting member 122 is fixedly connected to the operating handle 3 of the bottom valve member.

[0025] When the operating member 11 is in the closed state, the air valve 2 is closed, and the movable end of the second limiting member 122 is located in the first arc segment 1231 and is fixed by the slide groove 123. At this time, the operating handle 3 is limited and cannot rotate, so that the bottom valve member remains closed. When the operating member 11 rotates from the closed state to the open state, the air valve 2 switches to the open state, the first limiting member 121 is driven to rotate by the operating member 11, and the movable end of the second limiting member 122 moves from the first arc segment 1231 to the second arc segment 1232; when the second limiting member 122 is in the second arc segment 1232, the operating handle 3 can rotate to open or close the bottom valve member.

[0026] Furthermore, the linkage control device 1 of this embodiment further comprises a mounting box 13, which is fixed relative to the tank body. The operating member 11 has a rotating shaft 111, which is arranged at the end of the operating member 11. The operating member 11 is mounted in the mounting box 13 via the rotating shaft 111 to rotate relative to the tank body.

[0027] In this embodiment, the linkage control device 1 further includes a linkage assembly 14, through which the operating member 11 is linked with the switch of the air valve 2. Specifically, the linkage assembly 14 of this embodiment includes a linkage member 141 and a follower 142. The linkage member 141 is fixed on the rotating shaft 111 of the operating member 11 to rotate coaxially with the operating member 11. One end of the follower 142 is fixedly connected to the linkage member 141, and the other end is passed through the installation box 13 and connected to the switch of the air valve 2.

[0028] When the control member 11 is in the closed state, the switch of the air valve 2 is closed; when the control member 11 rotates from the closed state to the open state, the linkage member 141 rotates synchronously with the control member 11, and the rotating linkage member 141 can drive the follower 142, and the follower 142 moves to open the air valve 2. When the air valve 2 needs to be closed, the control member 11 is rotated to return it to the closed state, and at this time, the linkage member 141 rotates to drive the follower 142 to move, so that the switch of the air valve 2 is closed.

[0029] In this embodiment, the follower 142 is a flexible structure with a certain hardness, and the follower 142 can be a cable or a wire rope. In other preferred embodiments, the follower 142 can also be a hard structure, such as a connecting rod.

[0030] See also Figure 1 and Figure 2 When the control member 11 of this embodiment is in the closed state, the control member 11 is arranged vertically; when the control member 11 is in the open state, the control member 11 is arranged horizontally. When the control member 11 switches between the closed state and the open state, the rotation angle of the control member 11 is 90°.

[0031] Further, the first stopper 121 of the present embodiment is a plate-like structure, and the overall outer contour of the first stopper 121 is fan-shaped. The center angle of the first stopper 121 is fixed on the rotating shaft 111 of the operating member 11 to rotate coaxially with the operating member 11. In the present embodiment, the position between the first stopper 121 and the operating member 11 is fixed. When the operating member 11 switches between the closed state and the open state, the first stopper 121 can rotate synchronously with the operating member 11.

[0032] In this embodiment, the slide groove 123 is arranged at the arc edge of the first stopper 121. The arc length of the first arc segment 1231 is greater than the arc length of the second arc segment 1232. The first arc segment 1231 is bent in a direction away from the center of the first stopper 121, and the second arc segment 1232 is bent in a direction close to the center of the first stopper 121, so that the slide groove 123 is in an S-shaped bending state.

[0033] Furthermore, the center of the first arc segment 1231 of this embodiment is located on the rotating shaft 111 of the operating member 11, and the rotation angle of the operating member 11 from the closed state to the open state is equal to the center angle of the first arc segment 1231. When the operating member 11 is in the open state, the center of the second arc segment 1232 is located on the rotating shaft of the operating handle 3.

[0034] In this embodiment, the second position-limiting member 122 is fixed at the rotation axis of the operating handle 3 , and the rotation angle of the operating handle 3 when switching between the closed state and the open state is equal to the central angle of the second arc segment 1232 .

[0035] When the operating member 11 is in the closed state, the second stopper 122 is located in the first arc segment 1231 of the slide slot 123, and is disposed close to one end of the first arc segment 1231 away from the second arc segment 1232. When the second stopper 122 is located in the first arc segment 1231, the first stopper 121 and the second stopper 122 can prevent the operating handle 3 from rotating, so that the bottom valve member remains closed.

[0036] When the operating member 11 switches from the closed state to the open state, the operating member 11 rotates 90°, and the first limiting member 121 and the operating member 11 rotate 90° synchronously, and the second limiting member 122 moves along the first arc segment 1231 of the slide slot 123 to move from the first arc segment 1231 to the second arc segment 1232. When the second limiting member 122 is located in the second arc segment 1232, the first limiting member 121 and the second limiting member 122 can release the blocking of the operating handle 3, and the operating handle 3 can rotate to move the second limiting member 122 in the second arc segment 1232, thereby opening or closing the bottom valve member.

[0037] When the linkage control device 1 of this embodiment is in use, that is, when the air valve 2 needs to be opened before the bottom valve of the tank body is opened, the operating member 11 is rotated to switch it from the closed state to the open state, and the linkage member 141 rotates synchronously with the operating member 11 to drive the follower 142 to move, so as to open the switch of the air valve 2. During the rotation of the operating member 11, the first limiter 121 rotates synchronously with the operating member 11, so that the second limiter 122 located in the first arc segment 1231 moves to the second arc segment 1232. When the second limiter 122 is located in the second arc segment 1232, the bottom valve can be opened by rotating the operating handle 3, so as to realize the opening of the air valve 2 and then the opening of the bottom valve.

[0038] After the bottom valve is used, the operating handle 3 is first turned to close the bottom valve, and then the control member 11 is turned to restore it to the closed state. At this time, the first limiter 121 and the linkage member 141 rotate synchronously with the control member 11, and the second limiter 122 moves from the second arc segment 1232 to the first limiter 121, and the linkage member 141 drives the follower 142 to close the switch of the air valve 2.

[0039] The present application also provides a tank body, the bottom of the tank body is provided with a bottom valve, such as a loading and unloading valve, etc., and the top of the tank body is provided with an air valve 2. In this embodiment, the tank body is also provided with the above-mentioned linkage control device 1.

[0040] Specifically, the mounting box 13 is fixed relative to the tank body, and the operating member 11 is rotatably mounted in the mounting box 13. The follower 142 is connected to the switch of the air valve 2, and the second stopper 122 is connected to the operating handle 3 of the bottom valve member. When the second stopper 122 is located at the first arc segment 1231, the first stopper 121 and the second stopper 122 block the operating handle 3 to keep the bottom valve member closed.

[0041] When the operating member 11 switches from the closed state to the open state, the linkage member 141 rotates synchronously with the operating member 11 to drive the follower 142 to move, thereby opening the air valve 2. While the operating member 11 rotates, the first stopper 121 rotates synchronously to move the second stopper 122 to the second arc segment 1232. At this time, the first stopper 121 and the second stopper 122 release the blocking of the operating handle 3, and the operating handle 3 rotates to open the bottom valve member.

[0042] In this embodiment, a foot valve is further provided at the bottom of the tank body, and the foot valve is opened and closed by rotating a foot valve crank. The foot valve crank of this embodiment is linked with the operating handle 3, and when the operating handle 3 of the bottom valve member is rotated, the foot valve crank rotates synchronously with the operating handle 3 to open or close the foot valve.

[0043] In addition, the present application also provides a tank container, which includes a frame 4 and the above-mentioned tank body, and the tank body is supported by the frame 4. In this embodiment, the installation box 13 of the linkage control device 1 is fixed on the frame 4.

[0044] For the tank container, tank body and linkage control device of the present application, when the operating member is in the closed state, the air valve is closed. At this time, the second limit member is located in the first arc segment and is fixed by the slide groove so that the operating handle cannot be rotated, thereby keeping the bottom valve member closed; when the operating member is rotated from the closed state to the open state, the switch of the air valve is linked to open; at this time, the first limit member and the operating member rotate synchronously, and the second limit member enters the second arc segment to release the limit on the operating handle. The rotation of the operating handle can realize the opening of the bottom valve member to ensure the opening of the air valve before the loading and unloading valve is opened, thereby ensuring the stability of the internal pressure of the tank body and allowing the loading and unloading operations to proceed smoothly.
