Abstract
Description
Technical Field
[0001] This invention relates to the field of anti-scalding technology for replacing mud door rubber, specifically an anti-scalding tool for replacing mud door rubber. Background Technology
[0002] Dredgers are one of the important special vessels in shipbuilding or other marine engineering equipment. The design and construction of a 15,000 cubic meter high-intelligence trailing suction hopper dredger involves the design and arrangement of an automatic mud gate. The mud gate is used to discharge mud and sand from the mud tank of the dredger. The mud gate is located at the bottom of the tank and, as part of the mud tank, has high requirements for tightness and load. It is necessary to select the design form of the mud gate and arrange it reasonably by fully combining the structural characteristics of the hull. At the same time, the mud gate is required to have a large dumping capacity during mud unloading, high operating efficiency, and the ability to achieve automation.
[0003] The repair work includes replacing the rubber seals on the bilge doors. The bilge doors of dredgers are usually hydraulically operated. To ensure sealing and durability, the rubber strips around the doors are made of T-shaped solid hard rubber with deep rubber grooves.
[0004] Due to the unique installation method of this mud door rubber, when the rubber needs to be replaced, the inner side plate of the rubber groove must be removed before the rubber can be replaced. After the rubber is replaced, the inner side plate of the rubber groove needs to be reinstalled. However, the inner side plate is welded on one side only. If the rubber groove is welded in the conventional way, the welding process will inevitably damage the rubber, thereby compromising the rubber's liquid tightness and service life. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a heat-resistant fixture for replacing rubber in mud doors. It features an optimized welding method, employing segmented welding with liquid cooling, and incorporates anti-welding-splatter baffles. This solves the problem that when a rubber needs replacement, the inner side plate of the rubber groove must first be removed before replacement. After replacement, the inner side plate of the rubber groove needs to be reinstalled. However, the inner side plate is welded on one side only. If the rubber groove is welded using conventional methods, the welding process will inevitably damage the rubber, compromising its liquid tightness and lifespan.
[0007] (II) Technical Solution

The pipe is located above the splash baffle, and support blocks are located on both sides of the top of the splash baffle. A connecting pipe is located inside the support blocks, and a pipe is located at the top of the support blocks. A sleeve and a sleeve are respectively located at both ends of the pipe. A spray hole is located in the center of the front of the pipe, and valve sleeves are located on both sides of the spray hole. A bottom plate and a front plate are respectively located on both sides of the splash baffle. Rubber groove baffles are located near the top and bottom edges of the front of the splash baffle. A liquid storage box is located at the bottom of the splash baffle, and a liquid storage tank is located inside the liquid storage box. A pump is located on one side of the liquid storage tank, and holes are located at both ends of the liquid storage box. A heat-absorbing pipe is located inside the splash baffle.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a heat-resistant tool for replacing mud door rubber, which has the following beneficial effects:
[0019] 1. The new anti-scalding tooling for the mud door rubber is made by the cooperation of pipes, connecting pipes and heat absorption pipes. The liquid enters the pipes, enters the heat absorption pipes through the connecting pipes, and absorbs the heat generated during the welding of the splash baffle. The liquid carries the heat and is transported out through the pipes.
[0020] 2. This new anti-scalding tool for the mud door rubber replacement uses a sleeve and a rod to cooperate with each other, which facilitates the connection of pipes. The sleeve is fixed on the rod by rotating the thread, which is easy to disassemble and prevents damage that would require a lot of replacements. The thread makes it easy to fix and the structure is sturdy.
[0021] 3. This new anti-scalding tooling for the mud door uses a pump, spray holes, and a storage tank to work together. The liquid in the pipeline is sprayed onto the surface of the splash baffle through the spray holes, and then flows into the storage tank. The liquid inside the storage tank is drawn into the heat absorption pipe by the pump. The heat absorption pipe transports the liquid to the pipeline through the connecting pipe, forming a liquid self-circulation, avoiding liquid waste. The liquid circulation improves work efficiency, reduces equipment operating costs, and extends its service life by changing the heat transfer method.
[0022] 4. The new anti-scalding fixture for the mud door rubber uses a front plate and a bottom plate that fit together perfectly and are level with the splash baffle, facilitating welding. The bottom plate is designed to prevent the rubber groove from being damaged by heat during welding, thus compromising the rubber's liquid tightness and service life. Attached Figure Description
