AI Technical Summary

Technical Problem

The switching operation of the existing orifice cover plate has manual operation risks, high operation and maintenance costs, poor linkage and electric shock hazards, and the linkage control between the climbing device and the cover plate is not safe and efficient enough.

Method used

The rack and pinion meshing system driven by the climbing device's own power is used to convert chain motion through bevel gears to achieve automatic opening and closing of the cover. Combined with the safety control system and emergency operating mechanism, the synchronous operation of the cover and the climbing device is ensured.

Benefits of technology

The automatic opening and closing of the cover is realized, which improves work efficiency, reduces operation and maintenance costs, enhances safety and reliability, and reduces the risk of manual intervention and equipment collision.

Abstract

The present invention relates to an orifice coupling type automatic switch cover device and its installation and use method, which specifically includes a drive rack, a cover switch auxiliary mechanism, a personnel emergency operation mechanism, a cover device and a safety control system. The drive rack is installed on both sides of the climbing device, and the up and down movement of the climbing device is converted into the switch operation of the cover device through the engagement of the gear rack. The cover switch auxiliary mechanism realizes the conversion and transmission of driving force through mechanical transmission components such as gears, sprockets, and chains. The personnel emergency operation mechanism allows the cover to be manually opened and closed in the event of a system failure to ensure on-site safety. The safety control system is used to monitor the movement trajectory of the cover device on the support rail. The present invention realizes efficient and safe switching of the orifice cover through automatic control and mechanical linkage, which is particularly suitable for work environments that require frequent entry and exit of the orifice, greatly improving work efficiency and operational safety.
