Marine temporary handrail upright post and installation and use method thereof

Abstract

The invention discloses a marine temporary handrail upright post, which comprises an upright post, an upright post sleeve, a cross base and a spring, wherein the upright post sleeve is a hollow circular tube; the bottom of the upright post sleeve is fixed in the middle of the upper plate surface of the cross base; the upright post sleeve is provided with a plurality of bolt holes; the upright postis sleeved in the upright post sleeve; the upright post is fixedly connected with the upright post sleeve through a bolt; the upper plate surface of each cross edge of the cross base is fixed with awedge-shaped block with narrow upper part and wide lower part; the middle part of the lower plate surface of the cross base is fixed with the spring. The invention also discloses a method for installing and using the marine temporary handrail upright post. The method has the advantages of convenient assembly and disassembly and high system safety.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a temporary railing post for a ship and a method for installing and using the same. Background technique [0002] At present, in order to avoid the danger of personnel falling at the edge of the section or the large opening during ship construction, temporary protective railings are required. There are usually two fixing methods. One is to use on-site welding to temporarily weld the railing columns to At the fence; there is another way to use a threaded chuck, using a special clamp to clamp the railing post on the steel plate at the edge of the segment or at the opening. Although these two methods can meet the requirements of ship construction, after analysis, it is found that the traditional methods have the following shortcomings: [0003] 1. The on-site welding of railings requires the cooperation of welding machines and other equipment. The preparation time and welding time are l...

AI Technical Summary

Problems solved by technology

[0003] 1. On-site welding of railings requires the cooperation of welding machines and other equipment. The preparation time and welding time are long, and the outdoors will be restricted by rain and snow, which will affect the construction progress.

[0004] 2. During the welding of temporary railings and the subsequent dismantling by gas cutting, the high temperature generated will damage the coating of the deck, increasing the difficulty of coating protection

[0005] 3. The railing column in the form of a fixture must be installed at the edge of the steel plate, and during the installation and removal process, the construction personnel must be in the dangerous area on the edge of the opening to tighten (loosen) the fastening bolts, and the process itself has certain safety hazards
