Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe production, in particular to an auxiliary device and a transportation method for integrally transporting large-scale bendable corrugated pipes. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The wall of the bellows is thinner and the sensitivity is higher. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity.

[0003] If a large corrugated pipe is directly lifted at both ends by a crane during transportation, it is easy for the corrugated pipe to be damaged due to excessive local force. Therefore, when transporting large corrugated pipes, auxiliary devices are needed to expand the force-bearing area to reduce local pressure and protect the transportation of the corrugated pipe.

[0004] In the prior art, only an integrated structure similar to a ladder is used as an auxiliary device to expand the stress-bearing area. However, when this structure is used, the position where the bellows and the auxiliary device are separated is a vulnerable position, and the auxiliary device is prone to breakage. Although in actual operation, a reinforcement structure is used at the vulnerable position, the vulnerable position will vary depending on the position of the auxiliary device relative to the bellows during transportation and the effective length of the bellows. Therefore, when reinforcing the vulnerable position, it is necessary to perform reinforcement operations on a certain range of positions. Large-area reinforcement operations will increase the overall weight of the auxiliary device, thereby increasing the difficulty of inserting the auxiliary device into the bellows and increasing the difficulty of transportation operations. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the present invention provides an auxiliary device and a transportation method for the overall transportation of a large-scale bendable corrugated pipe, which solves the problem in the prior art that only an integrated structure similar to a ladder is used as an auxiliary device to expand the stress-bearing area. However, when this structure is in use, the position where the corrugated pipe and the auxiliary device are separated is a vulnerable position, and the auxiliary device is prone to breakage. Although in actual operation, a reinforcement structure is used at the vulnerable position, the vulnerable position will vary depending on the position of the auxiliary device relative to the corrugated pipe during transportation and the effective length of the corrugated pipe. Therefore, when reinforcing the vulnerable position, it is necessary to perform reinforcement operations on a certain range of positions. Large-area reinforcement operations will increase the overall weight of the auxiliary device, thereby increasing the difficulty of inserting the auxiliary device into the corrugated pipe.
