Problems solved by technology

This method of replacement is more complicated. Using a crowbar is easy to pry out the vertical beam, while the horizontal beam has a small working space and is not easy to use force. It may also deform the bottom surface of the bearing groove; cutting off the original fastening bolts not only increases the grinding The workload, the thermal cutting and re-welding will also deform the bottom surface of the bearing groove; it first opens a hole on the wood, and adds a pre-installation process in the wood bearing groove; the maintenance door is in an upright state, and the horizontal wood is not easy to install. And flatness measurement is difficult

Embodiment Construction

[0042] Such as Figure 1~Figure 12 Among them, a method for replacing a water seal of a floating inspection door includes the following steps:

[0043] S1, remove the wood screw 13 on the surface of the water stop plate 5 in the wood water stop groove, then remove the water stop plate 5 and the rubber water stop 4; remove the wooden plug on the original fastening bolt 1 of the wood 9 7. Then remove the fastening nut 2;

[0044] Further, when disassembling the fastening nuts 2, the disassembly sequence of the multiple fastening nuts 2 is to remove the fastening nuts 2 at the top of the floating door, and remove them one by one in the downward direction;

[0045] S2, remove multiple sections of vertical beams sequentially by prying up, and then remove the horizontal beams with a removal tool;

[0046] S3, after removing all the original beams 9, correct or replace the fastening bolts 1 inside the bearing groove 8, then polish the bearing groove 8 and the fastening bolts 1, and...

Abstract

The invention discloses a method for replacing a water seal of a floating access door. The method comprises the following steps that horizontal leaning wood is disassembled by using a disassembling tool consisting of a jack, a screw and a steel plate; the positions of fastening bolts in a bearing groove are sequentially placed to the surface of new leaning wood through a sample placing plate, the fastening bolts of the original leaning wood are reserved, and bolt cutting and rewelding do not need to be conducted; the horizontal leaning wood is mounted through a trolley and wooden wedges, and the leaning wood is accurately aligned in a narrow space; and a theodolite and an angle square are used to measure the flatness of the surface of the leaning wood. Compared with an existing replacement method, the method provided by the invention has the advantages that the construction steps can be simplified, and the construction amount is reduced; and through reasonable use of various tools, the construction intensity is reduced, and the access door water seal quality is improved.

Description

technical field [0001] The invention belongs to the field of hydraulic engineering equipment maintenance, and in particular relates to a method for replacing a water seal of a floating maintenance door. Background technique [0002] The floating inspection door is used as a water retaining door body during ship lock inspection and can be sunk into the door groove to realize water retention through the water seal and the door groove. The water seal of the floating inspection door is the most important part of its structure. If the water seal is aged and damaged, the water blocking effect of the inspection door will be greatly reduced. Therefore, it is extremely important to replace the water seal of the inspection door regularly; the replacement process is different from The whole process of initial construction and installation is carried out with the inspection door in an upright state, which is extremely difficult for the removal, installation, and level adjustment of the ...
