Description

Technical Field

[0001] This invention relates to the field of lifting device technology, specifically to an anti-tipping pressure vessel tilting machine. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels have extremely wide applications, playing a vital role in many sectors including industry, civil use, military, and scientific research. Their largest application is in the chemical and petrochemical industries, where they account for approximately 50% of all pressure vessels. In the chemical and petrochemical fields, pressure vessels are primarily used for heat transfer, mass transfer, and reaction processes, as well as for storing and transporting pressurized or liquefied gases. They also have wide applications in other industrial and civil sectors, such as in air compressors.

[0003] During the initial processing of pressure vessels, cylindrical pressure tanks require multiple processing steps, thus necessitating a change in their position. However, due to the significant weight of the pressure tanks, auxiliary tools are needed to achieve their rotation.

[0004] The existing Chinese publication CN117303208B discloses a pressure vessel tilting device, which includes a pressure tank, a crossbeam, and a crane. The two ends of the pressure tank are connected to the end of the crane via two sets of lifting ropes. It also includes a tilting auxiliary device, which includes a rotating mechanism, a clamping mechanism, and two sets of auxiliary lifting mechanisms. The rotating mechanism includes a support base and two sets of rotating arms. Each set of auxiliary lifting mechanisms includes a transmission mechanism and a lifting component. An auxiliary lifting rope is fitted from the bottom of the free end of the pressure tank. The auxiliary lifting mechanism of this device is used to provide a buffer force to the pressure tank during the process of tilting the pressure tank from horizontal to vertical, thereby ensuring the stability of the pressure tank during tilting and preventing the pressure tank from tipping over due to rapid rotation. At the same time, the two sets of rotating arms in the rotating mechanism of this device are equipped with limiting components to limit the rotation angle of the rotating arms, ultimately ensuring that the rotating arms will not continue to rotate to one side after the pressure tank is vertical.

[0005] However, this technical solution requires a hoisting rope and a crane, which limits its flexibility. For example, moving the entire tilting device requires moving the hoisting rope and the crane.

[0006] Therefore, we propose an anti-tilting pressure vessel overturning machine to solve the problems mentioned above. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-8 The present invention provides a technical solution: an anti-tipping pressure vessel overturning machine, comprising: a base frame 1 and a container bracket 4, with support frames 3 symmetrically fixedly installed on the left and right sides of the base frame 1, the upper end of the support frames 3 being rotatably connected to the container bracket 4, a hydraulic lifting mechanism 5 installed on the side of the base frame 1, the telescopic end of the hydraulic lifting mechanism 5 being rotatably connected to one end of a rotating arm 52, the other end of the rotating arm 52 being rotatably connected to the support frames 3 through a bearing, and the container bracket 4 being radially fixedly connected through a hexagonal prism 53;

[0039] The hydraulic lifting mechanism 5 drives the rotating arm 52 to rotate 90° counterclockwise, causing the container bracket 4 to rotate 90° counterclockwise. The pressure vessel is installed inside the container bracket 4, thereby enabling the pressure vessel to complete the flipping from horizontal to vertical.

[0040] A hydraulic station and an electrical control system can be built into the base frame 1 to improve overall flexibility.

[0041] The support frame 3 includes two symmetrically arranged triangular frames 31. The triangular frames 31 are fixedly connected to the base frame 1. The triangular frames 31 provide more stable support force. The upper end of the triangular frames 31 is relatively higher than the main body of the base frame 1. The side base 32 is fixedly installed on the upper end of the triangular frames 31. The side base 32 serves as the main support device for the container bracket 4. The side base 32 is rotatably connected to the container bracket 4 through bearings. The hexagonal prism 53 moves through the side base 32.

[0042] The container bracket 4 is suspended and rotatable by the tripod 31 and the side base 32, providing support and space for the pressure vessel to be overturned.

[0043] The hydraulic lifting mechanism 5 is mainly composed of a first hydraulic telescopic rod 51. The fixed end of the first hydraulic telescopic rod 51 is rotatably connected to the support frame 3, and the telescopic rod of the first hydraulic telescopic rod 51 is rotatably connected to the rotating arm 52. The rotating arm 52 is pushed to rotate by the first hydraulic telescopic rod 51.

[0044] A clamping device 6 is symmetrically installed on the container bracket 4. The clamping device 6 includes a support platform 61. A second hydraulic telescopic rod 62 and a clamping arm 63 are rotatably installed on the support platform 61. The middle part of the clamping arm 63 is rotatably connected to the telescopic end of the second hydraulic telescopic rod 62. The telescopic ends of the second hydraulic telescopic rods 62 of the two clamping devices 6 push the clamping arm 63 to rotate relative to the support platform 61. The two clamping arms 63 clamp the pressure vessel and fix it in the container bracket 4 to prevent the pressure vessel from detaching from the container bracket 4 in a vertical state.

[0045] When the container bracket 4 is in a horizontal state, its inner bottom surface is provided with several arc-shaped support platforms 8. The arc-shaped support platforms 8 are detachably installed with the container bracket 4. The arc-shaped grooves on the arc-shaped support platforms 8 fit against the outer wall of the pressure vessel, so that when the container bracket 4 is in a horizontal state, the arc-shaped support platforms 8 support the pressure vessel. Moreover, the curvature of the arc-shaped grooves of the arc-shaped support platforms 8 is preset to match the curvature of the outer wall of the pressure vessel, so that when the container bracket 4 is in a horizontal state, the arc-shaped support platforms 8 can provide more tight support.

[0046] When the container bracket 4 is in a horizontal state, a support seat 7 is fixedly installed on its inner left wall. The support seat 7 also adopts an arc surface design to adapt to the bottom conical surface of the pressure vessel. A support boss is fixedly installed at the center of the arc surface of the support seat 7. When the container bracket 4 is in a vertical state, the support seat 7 and the support boss provide support for the pressure vessel, making the pressure vessel more stable and not moving.

[0047] Side guide components 2 are symmetrically installed on both sides of the base frame 1. The side guide components 2 include fixed brackets, and guide modules are fixedly installed on the fixed brackets. The guide modules include two clamping plates 28, and a sandwich layer 21 is fixedly clamped between the clamping plates 28. A local cavity is formed between the sandwich layer 21 and the clamping plates 28.

[0048] The clamping plate 28 is provided with a slide rail groove 282, which is a 90° arc-shaped slide rail. A guide roller assembly 26 is slidably arranged in the slide rail groove 282. The guide roller assembly 26 is rotatably arranged on the middle surface of the rotating arm 52. Through the cooperation and sliding of the guide roller assembly 26 and the slide rail groove 282, the rotating arm 52 moves along the track, so that the first hydraulic telescopic rod 51 is kept in a plane during the extension and retraction process and will not deviate.

[0049] A lower clamping plate 23 and an upper clamping plate 22 are provided between the interlayer 21 and the interlayer plate 28. The lower clamping plate 23 and the upper clamping plate 22 are located on both sides of the slide rail groove 282, and both the lower clamping plate 23 and the upper clamping plate 22 include an arc-shaped rack 27. The lower clamping plate 23 and the upper clamping plate 22 are slidably connected to a guide rod 24. The guide rod 24 is fixedly installed in the interlayer 21. The lower clamping plate 23 and the upper clamping plate 22 are also connected to a cylinder 25. The cylinder 25 drives the lower clamping plate 23 and the upper clamping plate 22 to move linearly on the guide rod 24, so that the lower clamping plate 23 and the upper clamping plate 22 move closer or further away.

[0050] The guide roller assembly 26 includes a toothed roller 261. The lower clamping plate 23 and the upper clamping plate 22 move to clamp the toothed roller 261, so that the two arc-shaped racks 27 mesh with the toothed roller 261 at the same time, thereby fixing the toothed roller 261 and preventing it from moving. This achieves the emergency braking function of the guide roller assembly 26, and further achieves the emergency braking of the rotating arm 52 driving the container bracket 4.

[0051] The guide roller assembly 26 also includes a circular roller 262, which is located on both sides of the toothed roller 261. The circular roller 262 is slidably connected to the inner wall guide rail 281 and the slide rail groove 282. The inner wall guide rail 281 is fixedly installed on the inner wall of the interlayer 21, and the inner wall guide rail 281 is aligned with the edge of the slide rail groove 282, so that the circular roller 262 slides on both the slide rail groove 282 and the inner wall guide rail 281 at the same time. The arc-shaped rack 27 moves through the inner wall guide rail 281 and then contacts the toothed roller 261.

[0052] The circular roller 262 has a limiting plate 263 on its side. The limiting plate 263 is attached to the outer wall of the clamping plate 28 to limit the guide roller assembly 26, so that it slides along the inner wall guide rail 281 and the slide rail groove 282.

[0053] The circular roller 262 and the toothed roller 261 are coaxially rotatably connected to the connecting shaft 264, and the connecting shaft 264 is fixedly installed with the rotating arm 52.

[0054] Working principle: The pressure vessel is placed in the container bracket 4 and fixed by the clamping device 6. With the help of the support base 7 and the arc-shaped support platform 8, the pressure vessel is fixed in both the horizontal and vertical directions.

[0055] Start the hydraulic lifting mechanism 5, the first hydraulic telescopic rod 51 pushes the rotating arm 52 to rotate counterclockwise by 90°, and drives the container bracket 4 to rotate counterclockwise by 90° through the hexagonal prism 53, thus completing the flipping of the pressure vessel from the horizontal to the vertical direction;

[0056] During the flipping process, the rotating arm 52 moves in the vertical plane through the cooperation of the guide roller group 26 and the slide rail groove 282, preventing the extension end of the first hydraulic telescopic rod 51 from being deflected by force during the lifting process under the high gravity of the container bracket 4.

[0057] In case of an emergency during the flipping process, the cylinder 25 can drive the arc-shaped rack 27 to clamp the toothed rollers 261 of the guide roller assembly 26, thereby achieving emergency braking of the guide roller assembly 26 and thus emergency braking of the container bracket 4.

[0058] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
