Construction machinery, safety protection method and device for working at heights

Abstract

The invention discloses an engineering machine, a safety protection method and a device for high-altitude operations. In this safety protection method, firstly, the installation structure used for installation on the arm frame and the connectors and pin shafts required for assembling the locking assembly are preprocessed, the installation structure is processed with installation holes, and the connectors are processed with The pin shaft hole matched with the mounting hole through the pin shaft; secondly, fix the mounting structure on the arm frame, and assemble the connecting piece at both ends of the safety rope; finally, when in use, pass the The pin shaft connects the mounting hole of the mounting structure and the pin shaft hole of the connecting piece; after use, disassemble the pin shaft and release the connection between the mounting structure and the connecting piece; this method does not damage the On the premise of crane structural parts, "zero welding, detachable, expandable, versatile, and reusable" is realized through a simple shrinkage and tension structure. It has relatively high flexibility and safety in use.

Description

technical field [0001] The invention relates to the technical field of crane operation safety, in particular to an engineering machine, a safety protection method and a device for high-altitude operations. Background technique [0002] At present, safety protection measures are required for climbing operations in the construction machinery industry. In order to maintain the safety of operators, safety protection methods of welding fixtures are often used. [0003] At present, the safety protection of crane products usually adopts the direct welding fixed safety protection method. The protection device includes four welding fixed brackets on both sides of the boom, sleeve connecting rods, positioning sleeves, safety ropes, etc. Both ends of each safety protection wire rope are welded and fixed on the fixed brackets on both sides of the boom. The protection wire rope is first protected by the sleeve connecting rod, and the center is supported by a positioning sleeve to maintai...

AI Technical Summary

Problems solved by technology

[0005] The protective device is fixed at a specific position of the crane, cannot be moved, and has poor flexibility, so that the operator's construction work area is greatly limited, and if these welding devices need to work in multiple locations, it will take more welding. A device that affects the aesthetics and performance of the structural parts of the product

At the same time, after the construction of high-altitude operations, these protective devices must be disposed of, which will cause damage to the surface of the structural parts, and the safety hazards of high-altitude operations are relatively large, which is labor-intensive and time-consuming.

[0006] In addition, on-site practice found that the fixed safety protection method is adopted for the climbing operation on the jib of the crane product. Due to the diversification of product models, the length of the safety rope required by each crane product is different, which makes the design complicated; especially the fixed protection device The safety rope is exposed to the outdoors for a long time during the construction process. It is easily damaged by exposure to the sun, wind and rain, and it is not easy to clean and maintain in time, which reduces its service life and causes unnecessary waste.
