Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of safety rope fixing device, specifically relates to high place operation safety rope fixing device. BACKGROUND

[0002] Pipe gallery, namely, pipeline corridor, is the main place of large device pipeline centralized laying. Pipe gallery column refers to the vertical component supporting and constituting the pipe gallery structure. Its main function is to support and transfer the load of pipe gallery structure and auxiliary facilities, to ensure the safe operation and overall stability of the pipe gallery system. The pipe gallery column, together with the cross beam, truss and other components, forms a complete structure system to provide a stable support environment for the pipeline. In the pipe gallery operation, as the pipeline is usually erected in the air, the workers face the danger of falling from a high place when performing maintenance, repair or installation operations.

[0003] According to the requirements of GB30871-2022 "Safety Specification for Special Operations of Hazardous Chemical Enterprises", high place operators should correctly wear safety belts meeting the requirements of GB6095 and safety ropes meeting the requirements of GB24543. Petroleum and chemical enterprises have a large number of pipelines laid through pipe galleries. When performing pipeline installation, removal, corrosion prevention, and heat preservation operations in the pipe gallery, it is a high place operation, which requires wearing safety belts and safety ropes according to the requirements of GB0871 specification, and the safety belt should be hung high and used low. Now the safety belt mostly uses a double-hook five-point safety belt. Two hooks are connected to the safety belt through safety ropes. When in use, the two hooks must be hung on two different suspension points. When moving, the two hooks cannot be removed at the same time, and one hook must always be hung on the suspension point. This is to ensure that the wearer can be stably fixed on the safety rope in an emergency. Due to the dense arrangement of pipelines on the pipe gallery, there is no place to standardize the hanging of safety ropes, which brings insecurity to safety operation. The safety rope is generally simply hung on the pipeline or pipe gallery steel beam on site, which does not meet the requirement of hanging high and using low. UTILITY MODEL CONTENTS
