Description

Technical Field

[0001] The utility model relates to the field of molecular sieve bed disassembly and installation tooling, in particular to a special tooling for realizing the disassembly and installation of a columnar molecular sieve bed. Background Art

[0002] Molecular sieves are installed on certain types of aircraft. They use pressure swing adsorption technology and compressed air as raw material. The molecular sieves adsorb nitrogen and other gases to separate high-concentration oxygen from the air for use by pilots.

[0003] During the repair of molecular sieve, the product needs to be disassembled and reinstalled. Currently, there is no special disassembly and installation tooling. The current disassembly and installation method is for two people to cooperate in installation and disassembly, one person uses a press to squeeze the fastening parts, and the other person uses a wrench to loosen or tighten. The current installation and disassembly method is time-consuming, inefficient, and has a low success rate. The press has a poor fixing effect on the cylindrical molecular sieve. When the wrench is used to loosen or tighten, the molecular sieve will also rotate, making it difficult to achieve a loose or tightened state. It is also difficult for two people to keep pace and there are safety hazards. The quality of the molecular sieve bed cannot be guaranteed when installed and disassembled using this method. Problems such as airtight failure often occur. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0021] like Figure 1 As shown, a special tool for disassembling and installing a cylindrical molecular sieve bed includes a base 9 as a support for the tool, a plurality of groups of support bolts 10 arranged at the bottom of the base 9, and also includes:

[0022] A support assembly, mounted on the base 9, for providing support for various components of the tooling;

[0023] The downward pressure assembly cooperates with the supporting assembly to provide downward pressure to firmly fix the molecular sieve bed;

[0024] The disassembly and assembly components cooperate with the pressing components to dismantle or install the fixed molecular sieve bed.

[0025] The use of the utility model to install and decompose the molecular sieve bed according to the unique structural shape design of the product is not only safe and easy to operate, but also avoids the rotational displacement of the molecular sieve bed that may occur during the installation and decomposition of the product, provides downward pressure and side tightening force, avoids violent disassembly, and improves work efficiency and product repair quality.

[0026] The base 9 supports the entire tooling and is used to fix the lower part of the molecular sieve bed so as to ensure reliable contact between the molecular sieve bed and the base 9 and vertical axis.

[0027] The support assembly includes a back support plate 14, a side support plate 12 connecting the back support plate 14 and the base 9, and an upper support plate 3 fixed to the back support plate 14 by welding. There are four support bolts 10 for fixing the base 9 to a desktop or the ground with four-corner supports, thereby enhancing the stability of the tooling.

[0028] The side support plate 12 is triangular in shape, and the back support plate 14 is connected to the base 9 by welding, thereby enhancing the structural strength of the tooling and making the tooling more solid.

[0029] The upper support plate 3 is fixed to the back support plate 14 by welding and is screwed to the rotating shaft 2 to provide downward pressure during operation.

[0030] The pressing assembly includes a lower clamp 8 and an upper clamp 13 fixed to the back support plate 14 by high-strength bolts, a lower locking wrench 11 and an upper locking wrench 6 respectively cooperating with the lower clamp 8 and the upper clamp 13, and a rotating shaft 2 threadedly connected to the upper support plate 3.

[0031] The lower locking wrench 11 and the upper locking wrench 6 matched with the lower clamp 8 and the upper clamp 13 are used to clamp the side shell of the molecular sieve bed, increase the force-bearing area and thus increase the side friction between the shell and the clamp, so that the molecular sieve bed is firmly fixed.

[0032] The disassembly and assembly assembly comprises a hand wheel 1 connected to the rotating shaft 2 , a lower pressure plate 4 connected to the hand wheel 1 , and a special wrench 7 fixed to the upper clamp 13 via a special nut 5 .

[0033] The lower pressure plate is lowered by rotating the rotating shaft 2 through the hand wheel 1 to provide downward pressure perpendicular to the molecular sieve bed, thereby counteracting the upward elastic force of the internal spring of the molecular sieve bed on the molecular sieve bed fixing cover plate.

[0034] The special spanner 7 is fixed on the disassembly hole of the molecular sieve bed. When the molecular sieve bed tooling and the molecular sieve bed product are fixed, the molecular sieve bed fastening clamp ring is disassembled or installed.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
