Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field, especially a kind of vacuum chuck structure that can automatically adjust disc body position according to pipeline position. BACKGROUND

[0002] In the petroleum and natural gas pipeline hoisting operation, traditional mechanical lifting equipment (like truck crane) is gradually replaced by vacuum chuck because it is easy to cause rigid damage to the surface of the pipeline. Vacuum chuck realizes soft contact by negative pressure adsorption, with the advantages of high reliability and no damage. However, the existing vacuum chuck technology has obvious defects:

[0003] Poor ground adaptability: the pipeline is often placed on a non-horizontal ground, making it difficult for the disc body of the vacuum chuck to completely adhere to the pipeline, and the local air leakage problem is prominent, which poses a safety hazard to the hoisting.

[0004] Rigid connection drawbacks: the traditional disc body of the vacuum chuck is rigidly connected to the main body. When the pipeline is inclined, the entire vacuum chuck tilts, which easily causes the main structure to lose stability during hoisting, increasing the risk of operation.

[0005] Lack of adjustment capability: the existing vacuum chuck lacks a dynamic adjustment mechanism and cannot adapt to changes in the posture of the pipeline during hoisting, requiring frequent manual intervention, which seriously reduces the efficiency of the operation. INVENTION CONTENTS

[0006] To make up for the shortcomings of the prior art, the present application provides a vacuum chuck structure that can automatically adjust the position of the disc body according to the position of the pipeline to solve the problems existing in the prior art.

[0007] To solve the above technical problems, the utility model provides the following technical scheme:

[0008] A vacuum chuck structure that can automatically adjust the position of the disc body according to the position of the pipeline, comprising a lifting head, an upper guide device, a lower guide device, a chain, a compression spring, and a steel plate at the bottom of the compression spring, the upper guide device is set above the lower guide device, the compression spring is installed inside the upper guide device, one end of the chain is connected to the steel plate, the other end of the chain is connected to the lifting head, and the steel plate is integrally formed with the disc body.

[0009] As a further technical scheme of the utility model: the chain is divided into left and right two parts.

[0010] As a further technical scheme of the utility model: the upper guide device is a square tubular structure.

[0012] One or more technical solutions provided in the present application have at least the following technical effects or advantages:

[0013] 1. Improved ground adaptability: through dynamic adjustment mechanism, the suction cup body can automatically adjust with the pipe inclination angle, realizing efficient fitting and sealing of non-horizontal pipeline.

[0014] 2. Enhanced stability: ensure that the main body of the suction cup remains horizontal during the whole lifting process, avoiding instability risk caused by inclination.

[0015] 3. Improve automation level: reduce the need for manual intervention, improve hoisting operation efficiency and safety. BRIEF DESCRIPTION OF DRAWINGS

[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0020] As Figure 1As shown, a vacuum chuck structure capable of automatically adjusting the position of the disc body according to the position of the pipeline comprises an upper guide device 1, a lower guide device 2, a chain 3, a compression spring 4, and a steel plate 5 at the bottom of the compression spring 4, the upper guide device 1 is sleeved above the lower guide device 2, the compression spring 4 is installed inside the upper guide device 1, one end of the chain 3 is connected to the steel plate 5, the other end of the chain 3 is connected to a lifting head 7, and the steel plate 5 is integrally formed with a disc body 6, when the vacuum chuck is lowered from above the steel pipe, before the disc body 6 contacts the pipeline, the entire vacuum chuck is in a horizontal direction, after the vacuum chuck contacts the pipeline, because one end of the pipeline is high in position and the other end is low in position, the disc body 6 of the vacuum chuck preferentially contacts the high-positioned end of the pipeline, and as the vacuum chuck moves downward, because the main body of the vacuum chuck continues to move downward, the disc body 6 that has contacted the pipeline has no space to move downward, at this time, the spring 4 in the adjusting structure is compressed under the action of the main body of the vacuum chuck moving downward, at this time, the chain 3 above the disc body 6 is no longer stressed, until the other side of the disc body 6 of the vacuum chuck contacts the pipeline, after both sides of the disc body 6 contact the pipeline, the disc body 6 starts to be adsorbed to be lifted, as the pipeline is lifted, the compression spring 4 in the adjusting mechanism starts to be elongated, the disc body 6 of the vacuum chuck and the main structure of the vacuum chuck also return to the original state under the action of the upper guide square tube 1 and the lower guide square tube 2, and the chain 3 also starts to be stressed again, at this time, the disc body 6 and the pipeline are both in a horizontal state.

[0021] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
