DETAILED DESCRIPTION

[0036] 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 for illustrative purposes rather than for limiting the present invention.

[0037] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] When the cylinder of the tank container is square or round, due to the shape of the cylinder and the head, whether it is the simple method of crane hoisting the head or the ordinary combined tooling for auxiliary assembly, it is easy to make the cylinder difficult to align. Figure 1 As shown, when the cylinder 1 of the square round tank rotates on the self-adjusting roller frame 3, the center position changes and other problems may occur, which makes it difficult to keep the cylinder at a specific angle, making it difficult to align the end of the head and the end of the cylinder, causing difficulties in assembling the head and the cylinder, and further affecting the assembly efficiency of the square round tank. Therefore, a square round cylinder assembly tool is proposed to solve the above problems.

[0040] The scheme is further illustrated by the following examples:

[0041] It should be noted that, in this embodiment, after the cylinder 1 is placed on the assembly tool, the axial direction of the cylinder 1 itself extends in the horizontal direction.

[0042] See also Figure 2 and Figure 3 The square-round cylinder assembly tool of this embodiment is used to combine and assemble the cylinder 1 and the head 2, thereby facilitating welding of the cylinder 1 and the head 2.

[0043] In this embodiment, the square cylinder assembly tool comprises a base 10, a support ring mechanism 20 and a clamping claw mechanism 30. The support ring mechanism 20 comprises a support ring assembly 21 and a rotating assembly 22, wherein the support ring assembly 21 is used to clamp on the outer peripheral side of the cylinder 1, and the rotating assembly 22 is fixed on the base 10 and supported on the outer peripheral side of the support ring assembly 21, so that the support ring assembly 21 and the cylinder 1 can rotate along the rotating assembly 22, thereby adjusting the posture of the cylinder 1.

[0044] Specifically, the support ring assembly 21 includes an upper arc 211, a lower arc 212, and a stopper 213. The upper arc 211 is detachably connected to the lower arc 212, so that the upper arc 211 and the lower arc 212 can be spliced ​​into a ring, so that the ring can rotate along the rotating assembly 22. At the same time, a mounting portion 214 is provided on the inner wall of the upper arc 211 and the lower arc 212, and one end of the stopper 213 is detachably connected to the mounting portion 214, and the other end abuts against the outer peripheral side of the cylinder 1 to support and limit the cylinder 1.

[0045] It should be noted that there are multiple limit members 213, so that they can abut against the circumference of the cylinder 1 from different positions, thereby limiting the position of the cylinder 1. At the same time, the limit members 213 can be set according to the shape and model of the cylinder 1, so that after the upper arc 211 and the lower arc 212 are spliced ​​into a ring, the limit members 213 can abut against the circumference of the cylinder 1, thereby enabling the support ring assembly 21 to adapt to different models of cylinders 1, thereby expanding the scope of application of the assembly tooling.

[0046] In addition, the clamping mechanism 30 is used to grab the head 2 and can fit the head 2 to the end of the cylinder 1. Therefore, the upper arc 211 and the lower arc 212 can be spliced ​​into a ring, and the cylinder 1 is supported and limited by the limiter 213, so that the support ring assembly 21 is sleeved on the outer circumference of the cylinder 1. Since the upper arc 211 and the lower arc 212 are spliced ​​into a ring, when the ring rotates along the rotating assembly 22, it can drive the cylinder 1 to rotate along the axis of the ring, so that the posture of the cylinder 1 can be quickly adjusted to a specific angle, and then the clamping mechanism 30 can quickly fit the head 2 to the end of the cylinder 1, which is convenient for welding the cylinder 1 and the head 2.

[0047] See also Figure 2 In this embodiment, two groups of the base 10, the support ring mechanism 20 and the clamping mechanism 30 are provided, and the support ring mechanism 20 and the clamping mechanism 30 are provided on the same base 10. At the same time, the two support ring mechanisms 20 are provided on the same axis to support the two ends of the cylinder 1 at the same time, so as to ensure that the cylinder 1 remains stable during the posture adjustment process.

[0048] It should be noted that, in some other embodiments, the support ring mechanism 20 can be provided as one or more than two, so that the cylinder 1 is driven by the support ring mechanism 20 to rotate. In addition, the clamping mechanism 30 can be provided as one to fit the head 2 to the end of the cylinder 1.

[0049] In addition, in this embodiment, a guide rail 11 is provided on the base 10 , and the clamping mechanism 30 is connected to the base 10 via the guide rail 11 , so that the clamping mechanism 30 can move along the guide rail 11 and fit the head 2 to the end of the cylinder 1 .

[0050] In some other embodiments, the clamping mechanism 30 can also be connected to the base 10 through a mechanism such as a roller or a conveyor belt so as to be able to move relative to the base 10, thereby fitting the head 2 to the end of the cylinder 1.

[0051] See also Figure 2 The base 10 is also provided with a moving wheel 12. The moving wheel 12 is provided at the bottom of the base 10 so that the base 10 can be moved by the moving wheel 12. Thus, the distance between the two bases 10 can be adjusted, so that the assembly tool can adapt to cylinders 1 of different lengths and sizes, thereby expanding the application range of the assembly tool.

[0052] See also Figure 4-6 The stopper 213 is provided with an abutting top portion 45 and a connecting portion 46. The shape of the abutting top portion 45 is adapted to the shape of the outer peripheral side of the cylinder 1, so that the abutting top portion 45 can be fitted on the outer peripheral wall of the cylinder 1.

[0053] Meanwhile, the connecting portion 46 includes a connecting plate 461 and two fixing plates 462. The two fixing plates 462 are arranged in parallel and connected to the abutting portion 45. It should be noted that, in this embodiment, the mounting portion 214 is also provided with two mounting plates 215 which are parallel to each other, and one end of the mounting plate 215 is connected to the upper arc 211 or the lower arc 212. Specifically, the two fixing plates 462 are attached to both sides of the two mounting plates 215 to enhance the connection stability between the stopper 213 and the mounting portion 214.

[0054] In addition, the connecting plate 461 is connected to the side of the fixing plate 462 away from the abutting top portion 45 for installing the connecting member. It should be noted that the mounting portion 214 is also provided with a fastening plate 216 adapted to the connecting plate 461, and the fixing plate 462 and the fastening plate 216 are connected by a connecting member to install the stopper 213 on the mounting portion 214. The connecting member can be set as a bolt, a screw or a lock.

[0055] like Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, the stopper 213 can be set to different shapes so that the stopper 213 can be attached to the outer peripheral side of the cylinder 1 at different positions. Figure 5 The stopper 213 shown is used to be installed on the side of the upper arc 211 and the lower arc 212. Figure 7 The shown limiting member 213 is installed at the top of the upper arc 211 or the bottom of the lower arc 212, so that the multiple limiting members 213 on the upper arc 211 and the lower arc 212 can fit onto the outer peripheral side of the cylinder 1, so that the limiting members 213 can firmly press against the cylinder 1.

[0056] See also Figure 8 and Fig. 9 The lower arc 212 is provided with a support section 41 and two extension sections 42. The two extension sections 42 are respectively connected to the two ends of the support section 41, and the extension sections 42 can rotate downward along the connection, thereby reducing the height of the extension sections 42. It should be noted that after the extension sections 42 are lowered, it is convenient to place the cylinder 1 on the lower arc 212, thereby reducing the workload of hoisting the cylinder 1 on the lower arc 212.

[0057] See also Figure 8 and Fig.10 The lower arc 212 is also provided with a hinge 43 and a clamp 44. The hinge 43 and the clamp 44 are both connected between the support section 41 and the extension section 42, and are respectively located on both sides of the axial direction of the lower arc 212. In this embodiment, the hinge 43 is a hinge structure, and is arranged on the axial side of the lower arc 212, so that the extension section 42 can be located on the axial side of the lower arc 212 after rotating downward.

[0058] Of course, in some other embodiments, the hinge 43 may also be disposed on the radial side of the lower arc 212 so that the extension section 42 can rotate relative to the support section 41 .

[0059] In addition, the clamping member 44 is configured as a latch structure. After the extension section 42 is rotated to the end of the support section 41 through the hinge 43, the clamping member 44 is plugged together to fix the extension section 42 on the end of the support section 41 and prevent the extension section 42 from rotating relative to the support section 41.

[0060] See also Fig. 9 , the extension section 42 is provided with a mounting portion 214 for connecting the stopper 213. In this embodiment, the mounting portion 214 is provided on the extension section 42, so that the mounting portion 214 and the stopper 213 therein can rotate relative to the support section 41 following the extension section 42, thereby preventing the mounting portion 214 and the stopper 213 from affecting the placement of the cylinder 1 when the cylinder 1 is placed on the lower arc 212, thereby facilitating the placement of the cylinder 1 on the lower arc 212.

[0061] See also Fig.11 In this embodiment, three mounting portions 214 are provided on the upper arc 211 , so that a plurality of limiting members 213 can be installed to limit the outer peripheral side of the cylinder 1 .

[0062] In addition, if Fig.12 As shown, the upper arc 211 and the lower arc 212 are connected by bolts after being spliced, so as to ensure that the upper arc 211 and the lower arc 212 can be tightly connected together, thereby ensuring the supporting and limiting effect of the support ring assembly 21 on the cylinder 1.

[0063] See also Figure 2 and Fig.13 The rotating assembly 22 includes a roller 221 and a rotating seat 222. The rotating seat 222 is fixed on the base 10, and the roller 221 is connected to the rotating seat 222 and can rotate relative to the rotating seat 222. Rolling grooves are provided on the outer circumference of the upper arc 211 and the lower arc 212, and the rolling grooves are clamped on the outer circumference of the roller 221, so that the rolling grooves can rotate relative to the roller 221. That is, the support ring assembly 21 is limited on the roller 221 through the rolling grooves, and rotates relative to the rotating seat 222 along the upper arc 211.

[0064] See also Fig.13 The rotating assembly 22 further includes a rotating motor 223, which is mounted on the rotating seat 222 and connected to the roller 221 to drive the roller 221 to rotate, so that the roller 221 can drive the support ring assembly 21 to rotate. It should be noted that in some other embodiments, the rotating motor 223 can be omitted, and the support ring assembly 21 can be rotated manually.

[0065] See also Figure 2 The clamping mechanism 30 includes a support frame 31, a claw plate 32 and a telescopic rod 33. The support frame 31 is connected to the base 10 through a guide rail 11 to facilitate adjustment of the position of the support frame 31. The claw plate 32 is hinged on the support frame 31 so that the claw plate 32 can drive the end cap 2 to rotate between the vertical direction and the horizontal direction. The telescopic rod 33 is connected between the support frame 31 and the claw plate 32 to drive the claw plate 32 to rotate. In this embodiment, the claw plate 32 grabs the end cap 2 in the vertical direction, and rotates to the horizontal direction under the drive of the telescopic rod 33, and moves in the horizontal direction, so that the end cap 2 fits to the end of the cylinder 1.

[0066] In summary, in this embodiment, after the cylinder 1 is placed on the lower arc 212, the extension section 42 is fastened to the end of the support section 41, as shown in FIG. Fig.13 and Fig.14 Then, the upper arc 211 is spliced ​​to the lower arc 212, as shown in FIG. Fig.15 and Fig.16 As shown, the upper arc 211 and the lower arc 212 can support and limit the cylinder 1. Therefore, the assembly tool clamps the cylinder 1 by setting the support ring assembly 21, and rotates the cylinder 1 by the rotating assembly 22 to adjust the posture of the cylinder 1. At the same time, the head 2 is moved and attached to the end of the cylinder 1 by the clamping claw mechanism 30, so that the square cylinder 1 can be quickly aligned with the head 2, thereby improving the assembly efficiency of the cylinder 1 and the head 2, and facilitating the subsequent welding of the cylinder 1 and the head 2.
