Description

Technical Field

[0001] The invention relates to the technical field of lifting devices, in particular to an anti-overturning type pressure vessel overturning machine. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. Pressure vessels are widely used and play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most widely used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used in process such as heat transfer, mass transfer, reaction, and storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fields, such as air compressors.

[0003] During the initial processing of the pressure vessel, the cylindrical pressure tank needs to undergo multiple processing steps, so the pressure tank needs to switch its position state. However, since the pressure tank itself is heavy, auxiliary tools are needed to achieve the flipping of the pressure tank.

[0004] The existing Chinese publication number CN117303208B is a pressure vessel turning device, comprising a pressure tank, a crossbeam and a crane, wherein the two ends of the pressure tank are connected to the terminals of the crane through two sets of lifting ropes, respectively, and also comprises a turning auxiliary device, the turning auxiliary device comprises a rotating mechanism, a clamping mechanism and two sets of auxiliary lifting mechanisms, the rotating mechanism comprises a supporting seat and two sets of rotating arms, each set of auxiliary lifting mechanisms comprises a transmission mechanism and a lifting member, an auxiliary lifting rope is provided from the lower sleeve of the free end of the pressure tank, and the auxiliary lifting mechanism of the device is used to provide a buffer force for the pressure tank during the process of turning the pressure tank from horizontal to vertical, so as to ensure the stability of the pressure tank during turning, and prevent the pressure tank from tilting due to rapid rotation, and at the same time, the two sets of rotating arms in the rotating mechanism of the device are provided with limit members, and the limit members are used to limit the rotation angle of the rotating arms, and finally ensure that after the pressure tank is vertical, the rotating arms will not continue to rotate to one side; However, this technical solution requires a lifting rope and a crane, which results in certain limitations and inflexibility. For example, when moving the entire flipping device, the lifting rope and the crane need to be moved.

The pressure container is arranged in the container bracket 4, and the pressure container is turned from the horizontal direction to the vertical direction.

[0022] A hydraulic station and an electric control system can be built into the base frame 1 to enhance overall flexibility.

[0023] The support stand 3 includes two symmetrically arranged tripods 31, which are fixedly connected to the base frame 1. The tripods 31 provide a more stable supporting force. The upper end of the tripods 31 is relatively higher than the main part of the base frame 1. The upper end of the tripods 31 is fixedly installed with a side base 32, which serves as the main supporting device of the container bracket 4. The side base 32 is rotatably connected to the container bracket 4 through a bearing, and the hexagonal prism 53 movably penetrates the side base 32. The container bracket 4 is suspended by the tripod 31 and the side base 32 and can rotate, thereby providing support and turning space for the pressure container to turn over.

The arc-surface support platforms 8 and the container bracket 4 can be detachably installed. The arc-surface grooves on the arc-surface support platforms 8 fit with the outer wall of the pressure vessel, so that when the container bracket 4 is in a horizontal state, the arc-surface support platforms 8 support the pressure vessel.

A guide roller group 26 is slidably arranged in the slide rail groove 282, and the guide roller group 26 is rotatably arranged on the middle surface of the rotating arm 52. Through the coordinated sliding of the guide roller group 26 and the slide rail groove 282, the rotating arm 52 moves along the track, so that the first hydraulic telescopic rod 51 is guaranteed to be within a plane during the telescopic process without deviation.

[0029] A lower brake pressure plate 23 and an upper brake pressure plate 22 are arranged between the interlayer 21 and the clamping plate 28.

The lower brake pressure plate 23 and the upper brake pressure plate 22 move and clamp the toothed roller 261, so that the two arc-surface racks 27 are meshed with the toothed roller 261 at the same time, so as to fix the toothed roller 261 and prevent it from moving, thereby realizing the emergency braking function of the guide roller group 26, and then realizing the emergency braking of the container bracket 4 driven by the rotating arm 52; The guide roller assembly 26 further includes round rollers 262, which are located on both sides of the toothed roller 261.

The inner wall guide rail 281 is fixedly arranged on the inner wall of the interlayer 21, and the edges of the inner wall guide rail 281 and the slide rail groove 282 are aligned, so that the round rollers 262 slide on the slide rail groove 282 and the inner wall guide rail 281 at the same time, and the arc surface rack 27 moves through the inner wall guide rail 281 and then contacts the toothed roller 261. A limiting plate 263 is provided on the side of the round roller 262. 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. The circular roller 262 and the toothed roller 261 are coaxially rotatably connected to a connecting shaft 264 , and the connecting shaft 264 is fixedly installed to the rotating arm 52 .

[0030] Working principle: Place the pressure vessel in the vessel bracket 4, fix it by the clamping device 6, cooperate with the support seat 7 and the curved support platform 8, so that the pressure vessel is fixed both horizontally and vertically; The hydraulic pushing mechanism 5 is started, and the first hydraulic telescopic rod 51 pushes the rotating arm 52 to rotate 90° counterclockwise, and the container bracket 4 is driven to rotate 90° counterclockwise through the hexagonal prism 53, thereby completing the flipping of the pressure container from the horizontal direction to the vertical direction; During the flipping process, the rotating arm 52 moves on the vertical plane through the cooperation of the guide roller group 26 and the slide rail groove 282, and prevents the telescopic end of the first hydraulic telescopic rod 51 from being offset by force during the lifting process under the high gravity of the container bracket 4; During the flipping process, if an emergency occurs, the cylinder 25 can drive the arcuate rack 27 to clamp the toothed roller 261 of the guide roller group 26 to achieve emergency braking of the guide roller group 26, thereby achieving emergency braking of the container bracket 4.
