[0002] After the pressure vessel is produced, a series of processing needs to be performed on the outer wall surface of the pressure vessel, so the pressure vessel needs to be positioned. However, the existing positioning method is to place the pressure vessel horizontally and then install the pressure vessel in one place;

[0003] For example, when grinding a pressure vessel, the horizontally placed pressure vessel is rotated, and then the grinder moves linearly in the direction of the rotation axis of the pressure vessel, and the grinder grinds different positions of the pressure vessel.

[0004] However, the horizontal placement of the pressure vessel will make the installation process cumbersome. Due to the large size of the pressure vessel, it is generally necessary to hoist it. After hoisting, the pressure vessel is placed vertically. The vertical pressure vessel is laid flat and placed in the designated position for installation, which will be very cumbersome and difficult to operate. Summary of the invention

[0036] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] Reference Figure 1-9 ,

[0038] A vertical positioning device for a pressure vessel 1, wherein a plurality of legs 11 are welded to the outer wall of the pressure vessel 1; a positioning hole 12 is formed at the bottom of the legs 11. The legs 11 are rods, and three legs 11 are specifically provided. The three legs 11 can support the pressure vessel 1 in a vertically placed state.

[0039] The vertical positioning device for the pressure vessel 1 comprises a positioning member 2 and a driving member 3 .

[0040] The positioning member 2 is used to form a support surface 21 abutting against the bottom of the leg and a positioning protrusion 22 protruding outward relative to the support surface 21 and insertable into the positioning hole 12. In this embodiment, the positioning member 2 is a plate body, and the positioning protrusion 22 is a protruding rod.

[0041] The driving member 3 is used to drive the positioning member 2 to rotate so that the pressure container 1 is in a rotating state.

[0042] When the positioning protrusion 22 is inserted into the positioning hole 12 , the pressure container 1 and the positioning member 2 form a synchronously rotating combination.

[0043] In this embodiment, the driving member 3 adopts a motor, and the positioning member 2 is installed through a frame so that the positioning member 2 is restricted to one degree of freedom of rotation. The driving member 3 then drives the positioning member 2 to rotate, and the positioning protrusion 22 is inserted into the positioning space, so that the pressure vessel 1 rotates together with the positioning member 2.

[0044] Based on the above embodiments, in other embodiments, the positioning member 2 further forms a locking portion 241 that rises and falls relative to the support surface 21. The locking portion 241 protrudes outward relative to the support surface 21; the locking portion 241 falls relative to the support surface 21 under the action of an external force; the locking portion 241 rises relative to the support surface 21 when the external force is lost; the locking portion 241 forms a locking surface that is perpendicular to the support surface 21; and a plurality of the locking portions 241 are provided.

[0045] In a first specific embodiment, the positioning member 2 further forms a locking portion 241 that rises and falls relative to the supporting surface 21:

[0046] The locking portion 241 is the end of a rod made of elastic rubber. The rod made of elastic rubber provides the locking portion 241 with a force to rise relative to the support surface 21, and the locking portion 241 is compressed and deformed by the force to be acted upon by an external force, so that the locking portion 241 descends relative to the support surface 21. When the support foot is pressed on the support surface 21, the locking portion 241 that is not pressed down abuts against the edge of the support foot, thereby limiting the edge of the support foot, thereby providing partial support force for the support foot, reducing the shear force between the positioning protrusion 22 and the positioning hole 12 of the support foot during the rotation of the positioning member 2, thereby making it easier for the positioning protrusion 22 to realize its own function, and improving the service life and stability of the positioning protrusion 22.

[0047] In a second specific embodiment, the positioning member 2 further forms a locking portion 241 that rises and falls relative to the supporting surface 21:

[0048] The locking portion 241 is an elastic metal plate, which is in a transverse V-shape. One end of the elastic metal plate is fixed to the support surface 21 , and the other end protrudes outward relative to the support surface 21 .

[0049] In a third specific embodiment, the positioning member 2 further forms a locking portion 241 that rises and falls relative to the supporting surface 21:

[0050] The positioning member 2 includes: a moving block 23, a clamping rod body 24 and an elastic member 25. The moving block 23 is used to form the support surface 21, the positioning protrusion 22, the sliding chamber 231 and the installation chamber 232. The clamping rod body 24 is used to form the clamping portion 241 and the limiting portion 242; the elastic member 25 is arranged in the installation chamber 232, and the elastic member 25 is used to apply a force to the clamping portion 241 to rise relative to the support surface 21; the clamping rod body 24 is installed in the sliding chamber 231; the limiting portion 242 is used to limit the clamping portion 241 in the sliding chamber 231. A limiting chamber 233 is also formed in the moving block 23; the limiting portion 242 slides in the limiting chamber 233; the installation chamber 232 is connected with the sliding chamber 231 through the limiting chamber 233.

[0051] In the first specific embodiment, the elastic member 25 is used to apply a force to the locking portion 241 to rise relative to the supporting surface 21:

[0052] The elastic component 25 is a compression spring 251, and multiple compression springs 251 are provided. One end of the compression spring 251 abuts against the limiting portion 242 of the clamping rod body 24, and the other end abuts against the bottom surface of the installation chamber 232. The compression spring 251 applies a force to the clamping portion 241 to rise relative to the support surface 21 through the clamping rod body 24.

[0053] In a second specific embodiment, the elastic member 25 is used to apply a force to the locking portion 241 to rise relative to the supporting surface 21:

[0054] The elastic member 25 is sealed by high-pressure gas stored in the installation chamber 232, and the limiting portion 242 is slidably sealed with the limiting chamber 233. When the clamping portion 241 descends relative to the support surface 21, the limiting portion 242 moves to the limiting chamber 233. The high-pressure gas provides pressure to the limiting portion 242 away from the installation chamber 232, thereby providing the clamping portion 241 with a force to rise relative to the support surface 21. This solution can provide a force to rise relative to the support surface 21 for multiple clamping portions 241 at the same time through high-pressure gas, and the relative cost is greatly reduced.

[0055] In a third specific embodiment, the elastic member 25 is used to apply a force to the locking portion 241 to rise relative to the supporting surface 21:

[0056] The elastic member 25 includes: a spring 251 and a push plate 252; the push plate 252 abuts against the inner wall of the installation chamber 232, and the push plate 252 is filled with liquid; one end of the spring 251 contacts the push plate 252, and the other end of the spring 251 contacts the bottom surface of the installation chamber 232; the installation chamber 232 is connected to the sliding chamber 231. The liquid acts as a force transmission medium, and the spring 251 applies pressure to the liquid through the pressure plate, and the liquid simultaneously applies pressure to the limiting part 242, thereby providing a force for the locking part 241 to rise relative to the support surface 21. In this solution, the liquid used is water. Compared with the previous embodiment, since the sealing difficulty of water is much lower than that of air, the cost can be further controlled.

The positioning member 2 further includes a circular plate 4; the circular plate 4 is used to install the moving block 23 and the control member 6; the driving member 3 is used to drive the circular plate 4 to rotate.

[0058] In the first embodiment of the control member 6, a plurality of control members 6 are provided, each control member 6 is used to drive a positioning member 2 to move, and in this solution, the control member 6 is mounted on the circular plate 4.
