AI Technical Summary
Existing guide chain positioning mechanisms suffer from gaps between the guide chain and guide rollers due to wear, causing the guide chain to wobble, affecting the horizontal movement of the housing, resulting in non-horizontal linear force and difficulty in smooth sliding.
The system employs a frame and sleeve structure, with the sleeve fixed by a connecting rod. Inside the sleeve, a rotating shaft connects to a guide roller. A limiting component restricts the guide roller to move in only one direction. Compression springs and a dovetail groove structure ensure that the guide chain and the housing hook remain horizontal, and the relative movement between the guide chain and the guide roller prevents swaying.
It effectively prevents the guide chain from being subjected to non-horizontal forces on the hook of the housing, ensures the horizontal linear movement of the housing, reduces wear, and improves sliding efficiency.

[0002] The synthetic water cooling device is an indispensable equipment for synthetic ammonia production, and shell side scaling occurs several times during the use of the equipment, which leads to poor heat exchange effect. It seriously affects the process operation load, and if it is not cleaned for a long time, it will also cause electrochemical corrosion of metal. The formation of scale and rust scale leads to scale under corrosion of the inner wall of the heat transfer pipe, and the synthetic water cooling device needs to be pulled and shell-off treated by using a guide chain passing through a guide chain positioning mechanism. The guide chain positioning mechanism limits the guide chain so that the guide chain is always horizontal with the hooks on the shell body, facilitating the horizontal pulling of the shell body and ensuring the horizontal stress of the shell body. If the shell body cannot move horizontally, the rust scale will hinder the movement of the shell body and cause the shell body to jam.

The sleeve is fixed in the frame through a connecting rod, two support frames with guide rollers are fixedly embedded in the sleeve, the guide chain passes between the two guide rollers, the guide rollers position the guide chain, and when the guide chain slides between the guide rollers, long-term friction between the guide chain and the guide rollers causes the guide rollers to wear and causes gaps between the guide chain and the guide rollers. The guide chain is prone to shaking, which causes the guide chain and the hooks on the shell body to be not horizontal, resulting in non-horizontal linear stress of the shell body during movement, and the shell body is not convenient to slide.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0025] As shown in Figures 1-6 The present application provides the following technical solutions: a water cooler shell guide chain positioning mechanism, comprising a frame 1, a sleeve 2 is fixedly connected in the frame 1 through a plurality of connecting rods, two through grooves 3 are symmetrically opened at both sides of the sleeve 2, a support frame 5 is slidably arranged in the through groove 3, a guide roller 4 is rotatably connected in the support frame 5 through a rotating shaft, two support plates 13 are fixedly connected to the vertical rod side wall of the frame 1, a plurality of first compression springs 14 are fixedly connected between the vertical plate side wall of the support plate 13 and the support frame 5, a limiting assembly is fixedly connected to the vertical rod side wall of the frame 1, the output end of the limiting assembly is rotatably connected with the support frame 5, and the limiting assembly can limit the two guide rollers 4 to only move in one direction through the support frame 5.
[0026] Please combine Figure 1As shown, during use, the operating limiting assembly cancels the limiting of the support frame 5, and then the other end of the guide chain connected with the shell hook passes along the two guide rollers 4 and pushes the two guide rollers 4 to move in opposite directions. The guide roller 4 drives the support frame 5 to move and compress the first compression spring 14 to deform. Then the other end of the guide chain not connected with the shell hook is pulled to move, and the limiting assembly is loosened. The limiting assembly limits the support frame 5 to move in only one direction. The guide chain is gradually straightened, and the shell is pulled to move. The guide chain drives the guide roller 4 to rotate. When the guide chain is in contact with the guide roller 4 for a long time, the guide roller 4 is worn, and a gap is formed between the guide roller 4 and the guide chain. When the gap is formed, the first compression spring 14 pushes the support frame 5 to move, and the support frame 5 drives the guide roller 4 to move to clamp and position the guide chain again, so that the guide chain and the hook on the shell are always in a horizontal straight line state, thereby facilitating the horizontal movement of the shell under horizontal force.
