Description

Technical Field

[0001] The utility model relates to the technical field of tank containers, and particularly relates to a tank container and its connecting device. Background Art

[0002] During the production process of tank containers, most of them are rotated and positioned by installing auxiliary tooling on the head of the tank container and connecting the auxiliary tooling with external equipment.

[0003] The existing auxiliary tooling includes three process lugs for fixedly installing on the outer surface of the head, and a follower triangular plate connected to the head through the three process lugs. The three process lugs are respectively fixed at three corner positions of the follower triangular plate. The external equipment drives the head and the tank container to rotate and position by grasping the follower triangular plate.

[0004] Since the curved surface radii of the heads of special tanks with different specifications are different, when the follower triangular plate is connected to the outer surface of the heads with different curved surface radii through the three process lugs, the position of the follower triangular plate relative to the entire tank container is also different. Therefore, when batch-producing special tanks of multiple specifications, when the external equipment grasps the follower triangular plates on each head, it is necessary to continuously adjust the grasping position, which is time-consuming and laborious. Summary of the Utility Model

[0010] After each connecting seat is adjusted in place through the corresponding adjusting structure, one end of each connecting seat is relatively fixed to the connecting plate, and the end of each connecting seat far from the connecting plate is fixedly connected to the outer surface of the head.

[0011] In one embodiment, the adjusting structure includes an adjusting hole and an adjusting member. The adjusting hole is formed in the connecting plate.

It should be understood that the present utility model can have various variations in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the description of the positions of these elements changes, then the indication of these directions also changes accordingly.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0040] Please refer to Figure 1 As shown, the connecting device of the tank container 10 in the embodiment of the present utility model is used to connect the head 102 of the tank container 10 with external equipment. Among them, the tank container 10 includes a tank body 101 and heads 102 connected to both ends of the tank body 101. The head 102 can be a spherical curved head. The tank container 10 further includes a frame for supporting the tank body 101. The frame includes end frames 103 corresponding to the ends of the tank body 101.

[0041] As mentioned in the background art, the difference between special tanks of different specifications lies in the different curved surface radii of the heads 102. However, the sizes of the tank bodies 101 and frames of special tanks of different specifications can be the same. Therefore, in the case of mass-producing special tanks of multiple specifications, to improve production efficiency, it is necessary to ensure that the position of the accompanying triangular plate relative to the overall tank container 10 is constant, so that when the external equipment grabs special tanks of multiple specifications, there is no need to change the grabbing position.

[0042] Based on this, the connecting device of the tank container 10 in the embodiment of the present application can enable the connecting plate 100 to be adaptively connected to the heads 102 with different curved surface radii, while ensuring that the position of the connecting plate 100 relative to the overall tank container 10 remains unchanged.

[0043] Refer to Figure 1 and Figure 2As shown in the figure, the connecting device of the tank container 10 includes a connecting plate 100, a plurality of connecting seats 200, and a plurality of adjusting structures 300. The connecting plate 100 is perpendicular to the central axis of the tank body 101 of the tank container 10 and is located on the outer side of the head 102. The connecting plate 100 is used to connect with external equipment. Among them, the external equipment can be a tilting machine, which is used to drive the tank container 10 to rotate and position, facilitating the processing of the tank container 10.

[0044] A plurality of connecting seats 200 are respectively connected between the outer surfaces of the connecting plate 100 and the head 102, and the plurality of connecting seats 200 are arranged at intervals around the central axis of the tank body 101 of the tank container 10. Among them, each connecting seat 200 is mainly used to fixedly connect the connecting plate 100 and the head 102. A plurality of adjusting structures 300 are correspondingly arranged between the connecting plate 100 and the plurality of connecting seats 200. Each connecting seat 200 is connected to the connecting plate 100 through the corresponding adjusting structure 300, and each adjusting structure 300 is respectively used to adjust the distance between each connecting seat 200 and the central axis of the tank body 101 of the tank container 10. After each connecting seat 200 is adjusted in place through the corresponding adjusting structure 300, one end of each connecting seat 200 is relatively fixed to the connecting plate 100, and the end of each connecting seat 200 away from the connecting plate 100 is fixedly connected to the outer surface of the head 102.

[0045] It should be noted that the fact that each connecting seat 200 is adjusted in place through the corresponding adjusting structure 300 specifically means that on the premise of ensuring that the position of the connecting plate 100 relative to the overall tank container 10 is positioned at a preset position, the adjusting structure 300 can adjust the position of the connecting seat 200 until the end face of the connecting seat 200 away from the connecting plate 100 can contact and fit tightly with the outer surface of the head 102, at which time the connecting seat 200 is adjusted in place. After the connecting seat 200 is adjusted in place, the connecting seat 200 is relatively fixed to the connecting plate 100, and the end of the connecting seat 200 away from the connecting plate 100 is fixed to the outer surface of the head 102.

[0046] The connecting device of the tank container 10 in the embodiment of the present application includes a connecting plate 100, a plurality of connecting seats 200, and a plurality of adjusting structures 300. Each adjusting structure 300 can adjust the position of each connecting seat 200, so that the connecting seat 200 can be adapted to connect the connecting plate 100 on the heads 102 with different surface radii, while ensuring that the position of the connecting plate 100 relative to the tank container 10 remains unchanged. Therefore, when connecting the heads 102 of different specifications of tank containers 10 to external equipment, since the position of the connecting plate 100 on each tank container 10 remains unchanged, the grasping position of the external equipment when grasping the connecting plate 100 does not need to be changed either. This can save the adjustment time of the external equipment and greatly improve the work efficiency.

[0047] Such as Figure 2As shown, in one embodiment, the connecting plate 100 can be an equilateral triangle. The center of the connecting plate 100 coincides with the central axis of the tank body 101 of the tank container 10. In this embodiment, the connecting plate 100 is an equilateral triangle, which has high structural stability and is conducive to reliable connection with external equipment.

[0048] As Figure 2 shown, the number of the connecting seats 200 can be three. The three connecting seats 200 are arranged in an equilateral triangle. Specifically, the three connecting seats 200 are respectively arranged at the three corner positions of the connecting plate 100. Among them, when each connecting seat 200 is fixed to the outer surface of the head 102, the distances between the three connecting seats 200 are equal to each other. And the distances from the three connecting seats 200 to the central axis of the tank body 101 of the tank container 10 are equal. Thereby, the connection strength between the connecting plate 100 and the head 102 can be made uniform, which is conducive to improving the stability and safety of the rotation and displacement operation of the tank container 10.

[0049] In the embodiment of the present application, the connecting plate 100 is an equilateral triangle plate, and the number of the connecting seats 200 is three. However, the present application is not limited thereto. In other embodiments, the connecting plate 100 can also be other regular polygon structures; or the connecting plate 100 is a circular plate; or the connecting plate 100 is a structure with other irregular shapes, as long as it is ensured that the rotation center of the connecting plate 100 can coincide with the central axis of the tank body 101 of the tank container 10, so that the external equipment can drive the tank container 10 to rotate stably through the connecting plate 100. The number of the connecting seats 200 can be two, four or five, etc., which can be determined according to the specific situation. For example, the positions and the number of the connecting seats 200 can be designed adaptively according to the shapes, sizes, etc. of the connecting plate 100 and the head 102, so as to achieve the purpose of reliable connection between the connecting plate 100 and the head 102.

[0050] In the embodiment of the present application, each connecting seat 200 is connected to the connecting plate 100 through an adjusting structure 300. Before fixing each connecting seat 200 to the outer surface of the head 102, the position of the connecting seat 200 can be adjusted first through the adjusting structure 300 to adapt to connecting the connecting plate 100 to the head 102 with different surface radii.

[0051] Referring to Figure 2 , in one embodiment, the adjusting structure 300 includes an adjusting hole 310 and an adjusting member 320. The adjusting hole 310 is opened on the connecting plate 100. The adjusting hole 310 is a long strip hole, and the length extending directions of the multiple adjusting holes 310 can intersect on the central axis of the tank body 101 of the tank container 10.

[0052] As Figure 2As shown, taking the connecting plate 100 as an equilateral triangle plate as an example, three long adjusting holes 310 are respectively formed at three corner positions on the connecting plate 100. The two ends of each adjusting hole 310 in the length direction respectively point to the vertex and the center point of the connecting plate 100.

[0053] As Figure 3 shown, one end of the adjusting member 320 is connected to the connecting seat 200. By way of example, the adjusting member 320 is a bolt, and a connecting hole for passing through the screw rod of the bolt is provided on the connecting seat 200. In this embodiment, the adjusting member 320 is a bolt, and it is detachably connected to the connecting seat 200.

[0054] In other embodiments, the adjusting member 320 may also be a threaded post structure fixed on the connecting seat 200.

[0055] As Figure 3 shown, the other end of the adjusting member 320 is slidably disposed in the adjusting hole 310 and connected to the connecting plate 100. Each connecting seat 200 can slide along the adjusting hole 310 through the adjusting member 320. After each connecting seat 200 slides in place, the adjusting member 320 relatively fixes the connecting seat 200 and the connecting plate 100.

[0056] When assembling the connecting device on the outer surface of the head 102, first pre-connect each connecting seat 200 and the connecting plate 100 through the adjusting member 320, that is, the bolt. At this time, each connecting seat 200 can respectively slide in the adjusting hole 310 of the connecting plate 100 through the bolt. During actual operation, each connecting seat 200 can be first located at one end of each adjusting hole 310 close to the vertex of the connecting plate 100. Position the connecting plate 100 at a position spaced a preset distance from the end of the tank container 10. Refer to Figure 3 shown. By way of example, the connecting plate 100 can be positioned at a position spaced a preset distance M from the end frame 103 of the tank container 10. At this time, the position where the connecting plate 100 is located is also the grasping position of the external device.

[0057] After the position of the connecting plate 100 is determined, slowly move each connecting seat 200 along the direction from the vertex to the center point of the connecting plate 100, so that the end of each connecting seat 200 away from the connecting plate 100 abuts against the outer surface of the head 102 and fits as closely as possible. Tighten the bolt to relatively fix each connecting seat 200 and the connecting plate 100. Weld and fix the end of each connecting seat 200 away from the connecting plate 100 to the outer surface of the head 102. Thus, the connecting device can be assembled on the outer surface of the head 102.

[0058] It can be understood that the connecting plate 100 is used for being grasped by an external device so that the external device can process the tank container 10. After the tank container 10 is processed, the connecting plate 100 can be disassembled. Or cut each connecting seat 200 from the head 102. Of course, the connecting plate 100 and the connecting seat 200 can also be used together with the tank container 10 when leaving the factory.

[0059] As Figure 1 and Figure 3 shown, it shows a schematic diagram of the connecting device assembled on the head 102 with a smaller curved surface radius. Refer to Figure 1 and Figure 3 shown, the connecting plate 100 is connected to the head 102 with a smaller curved surface radius through each connecting seat 200. At this time, the distance between each connecting seat 200 is relatively large, and the distance from each connecting seat 200 to the central axis of the tank body 101 is also relatively large. And the connecting plate 100 is spaced from the end of the tank box 10 by a preset distance M.

[0060] As Figure 4 shown, it shows a schematic diagram of the connecting device assembled on the head 102 with a larger curved surface radius. Refer to Figure 4 shown, the connecting plate 100 is connected to the head 102 with a larger curved surface radius through each connecting seat 200. At this time, the distance between each connecting seat 200 is relatively small, and the distance from each connecting seat 200 to the central axis of the tank body 101 is also relatively small. And the connecting plate 100 is spaced from the end of the tank box 10 by a preset distance M.

[0061] When assembling the connecting device of the tank box 10 in the embodiment of the present application, first position the connecting plate 100 relative to the head 102. Specifically, position the connecting plate 100 to a position where it is spaced from the end of the tank box 10 by a preset distance M, and at the same time, ensure that the center of the connecting plate 100 coincides with the central axis of the tank body of the tank box 10.

[0062] Then, adjust the positions of the connecting seats 200 through each adjusting structure 300 so that the ends of the connecting seats 200 away from the connecting plate 100 can fit the outer surface of the head 102, and then weld and fix the connecting seats 200 to the head 102, and relatively fix each connecting seat 200 to the connecting plate 100.

[0063] Since the position of the connecting plate 100 is always positioned at a position spaced from the end of the tank box 10 by a preset distance M, the position for the external device to grasp the connecting plate 100 can remain unchanged. At the same time, since the adjusting structure 300 can adjust the positions of the connecting seats 200, the connecting seats 200 can be installed to be compatible with heads 102 with different curved surface radii. The connecting device of the tank box 10 in the embodiment of the present application can be quickly and accurately installed on the head 102 without changing the position for the external device to grasp the connecting plate 100, reducing the adjustment time of the external device and improving work efficiency. It can adapt to heads 102 of various specifications and meet the production situation of special tanks in small batches and with multiple varieties.

[0064] Refer to Figure 2 and Figure 3In one embodiment, the connection device of the tank box 10 further includes a guide structure 400 disposed between the connection plate 100 and the connection seat 200. The guide structure 400 is used to guide the sliding of the connection seat 200 along the adjustment hole 310. By providing the guide structure 400, the sliding of the connection seat 200 along the adjustment hole 310 can be guided, thereby improving the smoothness and accuracy of the movement of the connection seat 200 relative to the connection plate 100.

[0065] like Figure 2 As shown, in one embodiment, the guide structure 400 includes a guide block 410 and a guide groove 420. The guide block 410 is arranged on the connecting plate 100 corresponding to each adjustment hole 310. The guide block 410 is a long strip structure, and a long strip through hole corresponding to the adjustment hole 310 is opened on the guide block 410. In this embodiment, the guide block 410 is arranged at each adjustment hole 310 of the connecting plate 100. The long strip through hole on the guide block 410 is connected to the adjustment hole 310 on the connecting plate 100 to form a hole for the adjustment member 320 to pass through.

[0066] The guide groove 420 is provided on the connection base 200 corresponding to the guide block 410, and the guide block 410 is slidably matched with the guide groove 420. In this embodiment, by providing the guide block 410 and the guide groove 420 for sliding cooperation, a guide is provided for the connection base 200 to slide along the adjustment hole 310. At the same time, the provision of the guide block 410 also enhances the structural strength of the adjustment hole 310 of the connection plate 100, thereby facilitating the improvement of the connection strength of the connection device.

[0067] In other embodiments, the positions of the guide block 410 and the guide groove 420 may also be interchanged. That is, the guide block 410 is disposed on the connection seat 200 , and the guide groove 420 is disposed on the connection plate 100 .

[0068] See also Figure 1 In one embodiment, the connection device of the tank container 10 further includes a positioning member 500, which is disposed at the center of the connection plate 100. The central axis of the positioning member 500 coincides with the central axis of the tank body 101 of the tank container 10, and the positioning member 500 can move toward the end cap 102 and abut against the outer surface of the end cap 102.

[0069] In one embodiment, the positioning member 500 may be a needle-shaped structure. For example, the positioning member 500 may be an ejector pin. The ejector pin may be a cylindrical ejector pin. When the positioning member 500 abuts against the outer surface of the sealing head 102, the tip of the positioning member 500 coincides with the center of the sealing head 102.

[0070] In this embodiment, since the positioning member 500 is arranged at the center of the connecting plate 100, when the central axis of the positioning member 500 coincides with the central axis of the tank body 101 of the tank container 10, the center of the connecting plate 100 coincides with the central axis of the tank body 101 of the tank container 10. Thus, the position of the connecting plate 100 on the plane perpendicular to the central axis of the tank body 101 of the tank container 10 can be positioned by the positioning member 500.

[0071] Moreover, the positioning member 500 can move towards the head 102 and abut against the outer surface of the head 102. When the position of the connecting plate 100 relative to the end of the tank container 10 is determined, the positioning member 500 can be made to move towards the head 102 and abut against the outer surface of the head 102, so as to keep the connecting plate 100 in this position.

[0072] In one embodiment, a threaded hole is provided at the center of the connecting plate 100, and an external thread that is threadedly engaged with the threaded hole is provided on the outer peripheral surface of the positioning member 500. By providing the external thread to be threadedly connected with the threaded hole, a connection in which the positioning member 500 and the connecting plate 100 can move relative to each other can be achieved, and the positioning member 500 can be made to abut against the outer surface of the head 102 as needed. Through the external thread and the threaded hole, it is also convenient to remove the positioning member 500 from the connecting plate 100, so that the positioning member 500 can be reused.

[0073] In other embodiments, the positioning member 500 can also be a screw.

[0074] In one embodiment, scale lines arranged along the axial direction of the positioning member 500 can also be provided on the outer peripheral surface of the positioning member 500. These scale lines can record the length that the end of the positioning member 500 used to abut against the head 102 extends from the surface of the connecting plate 100. Refer to Figure 4 As shown, when the connecting device is fixed to the head 102 and the connecting plate 100 is spaced apart from the end of the tank container 10 by a preset distance M, the length that the end of the positioning member 500 used to abut against the head 102 extends from the surface of the connecting plate 100 is recorded. When the positioning member 500 is removed and reused on the next connecting plate 100, when this connecting plate 100 is connected to the head 102 of the same specification through the connecting seat 200, according to the previously recorded length, the position of the connecting plate 100 can be quickly positioned by the positioning member 500.

[0075] Refer to Figure 1 As shown, an embodiment of the present utility model further provides a tank container 10, including a tank body 101 and heads 102 connected to both ends of the tank body 101, and the connecting device of the tank container 10 as described in any of the above embodiments. Among them, the connecting plate 100 is connected to the head 102 through a plurality of connecting seats 200. The connecting plate 100 is used for being grabbed by an external device so that the external device can process the tank container 10.

[0076] Since an adjusting structure 300 is provided between the connecting plate 100 and the connecting seat 200, the adjusting structure 300 can adjust the positions of the connecting seats 200. Therefore, the position of the connecting plate 100 on the head 102 of the tank container 10 relative to the tank container 10 is always constant. Thus, when an external device processes the tank container 10, there is no need to adjust the grasping position, which greatly improves the working efficiency.

[0077] When assembling the tank container 10 according to the embodiment of the present utility model:

[0078] Each connecting seat 200 can be first connected to the connecting plate 100 through each adjusting structure 300. By way of example, the connecting seat 200 is connected to the connecting plate 100 by bolts. The bolts are slidably disposed in the adjusting holes 310 on the connecting plate 100.

[0079] Then, the connecting plate 100 is positioned at a position spaced a preset distance from the end face of the tank container 10. By way of example, the connecting plate 100 can be positioned at a position spaced a preset distance M from the end frame 103 of the tank container 10. This position is also the grasping position of the external device.

[0080] After that, the positions of the connecting seats 200 are adjusted through the adjusting structures 300 so that the ends of the connecting seats 200 away from the connecting plate 100 are abutted against the outer surface of the head 102. By way of example, each connecting seat 200 can be first located at one end of the adjusting hole 310 close to the vertex of the connecting plate 100. After the position of the connecting plate 100 is determined, each connecting seat 200 is slowly moved along the direction from the vertex to the center point of the connecting plate 100 so that the ends of the connecting seats 200 away from the connecting plate 100 are abutted against the outer surface of the head 102 and are as closely fitted as possible.

[0081] Finally, the connecting seats 200 and the connecting plate 100 are relatively fixed, and the ends of the connecting seats 200 away from the connecting plate 100 are fixed to the outer surface of the head 102. Specifically, the bolts connecting the connecting seat 200 and the connecting plate 100 are tightened so that the connecting seat 200 and the connecting plate 100 are relatively fixed. The ends of the connecting seats 200 away from the connecting plate 100 are welded and fixed to the outer surface of the head 102.

[0082] The assembling method of the tank container 10 according to the embodiment of the present application is to first position the connecting plate 100 relative to the head 102. Specifically, the connecting plate 100 can be positioned at a position spaced a preset distance M from the end of the tank container 10. At the same time, it is ensured that the center of the connecting plate 100 coincides with the central axis of the tank body of the tank container 10.

[0083] Then, adjust the positions of the connecting seats 200 through the respective adjusting structures 300 so that the ends of the connecting seats 200 away from the connecting plate 100 can be attached to the outer surface of the head 102. Then, weld and fix the connecting seats 200 to the head 102, and relatively fix the connecting seats 200 to the connecting plate 100. Thus, the connecting plate 100 can be fixed to the outer surface of the head 102 through the respective connecting seats 200, and it is ensured that the connecting plate 100 is always located at a position spaced from the end of the tank container 10 by a preset distance.

[0084] Through this assembly method, the connecting device of the tank container 10 in the embodiment of the present application can be quickly and accurately installed on the head 102, without changing the position where the external device grabs the connecting plate 100, reducing the adjustment time of the external device, and improving work efficiency. It can adapt to heads 102 of various specifications and meet the production situation of special tanks with small batches and multiple varieties.
