Description

Technical Field

[0001] The invention relates to the technical field of shaft construction, in particular to a shaft temporary sealing airbag module. Background Art

[0002] In the construction of the shaft, a single-layer bidirectional steel bar through-protection mesh is usually combined with the template hard closure to ensure the safety of objects in the shaft and prevent the impact and high-fall accidents caused by falling objects from heights. This technology can effectively provide a static protective barrier and play a certain role in ensuring the safety of the construction process.

[0003] However, the existing technology also has some obvious shortcomings:

[0034] 2. The shaft temporary closed airbag module is designed with rotatable embedded bolts, which makes it easy to install the wall mounting rail on the shaft beam, and convenient for subsequent disassembly, replacement and maintenance. The device further designs the card slot, card block and locking mechanism to facilitate the docking operation between the wall mounting rail and the airbag bracket, thereby facilitating the disassembly and assembly of the airbag bracket and the airbag body. Therefore, the entire temporary closed airbag module is easy to disassemble and reuse, which reduces costs and improves the practicality and safety performance of the temporary closed airbag module.

[0035] 3. The airbag module is temporarily closed in the well.

The airbag body is designed with an anti-puncture layer and a wear-resistant layer, so that the surface of the airbag body is puncture-resistant and wear-resistant, with good stability. It has good support and protection for the inside of the well and is not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The embodiments of the present application solve the problems of high applicability and transportation and storage requirements of steel mesh by providing a temporary shaft sealing airbag module. For shaft openings of special shapes or sizes, additional cutting and splicing are required, which increases the construction difficulty and cost. The construction and maintenance costs of the hard sealing structure are high. Usually, the hard sealing structure cannot be reused after being dismantled at a later stage. There are also certain safety risks in the dismantling process. The protection form is single. If there is a fault in the steel mesh, the existing technology lacks monitoring means and cannot monitor abnormal conditions in the construction process in real time. When an unexpected situation occurs, failure may occur and cause losses.
