Recently, a \"maintenance and repair core-pulling device\" developed by Sinochem Fourth Construction Company was granted a **utility model patent, with the patent number ZL2019208879608.9. This inspection, maintenance, and core-pulling device features a simple structure, low manufacturing cost, and ease of use; it includes a support, U-shaped guide rails, and towing lugs. Among them, the U-shaped guide rail consists of several guide strips arranged in an arc shape, with both ends fixed by two semi-circular plates. Two support blocks are located at the lower part of the U-shaped guide rail, and a first connecting plate is placed at the bottom of these support blocks. The support consists of a base plate and pillars; a second connecting plate is installed at the top of the pillars, and the second connecting plate is connected to the first connecting plate via bolts. The towing lug plate includes a third connecting plate and 2 lugs; each lug is equipped with a connecting hole. The semi-circular plate is connected to the towing lug plate via bolts, and corresponding bolt holes are provided. The 2 lugs of the towing lug plate face inward toward the U-shaped guide rail.

The core-pulling device for inspection and maintenance manufactured using this patent can have its size determined based on the dimensions of the heat exchanger whose core is to be pulled. The various components are first prefabricated in a manufacturing facility and then assembled at the site where core pulling takes place; it is particularly suitable for operations in confined spaces, such as with heat exchangers that are small in size and weight.
Such devices are one-of-a-kind; their cost must be quite high, right?
It shouldn’t be complicated; since a practical patent has already been applied for and the drawings must be made public, it’s necessary to discuss matters with Sihua Jian. I’m thinking that for some factories that haven’t yet undergone major repairs, and where individual heat exchangers are clogged or leaking, it would be possible to acquire spare core-pulling equipment so as to handle the inspection and maintenance tasks on one’s own.
Utility model technology is indeed an important means of solving certain problems
