Technical Field

[0001] The invention relates to a method for disassembling and replacing a carbon dioxide gas cylinder. Background Art

[0002] During the aluminum strip production process, carbon dioxide is often used to cool the strip and isolate oxygen from the air to prevent sparks from friction between the strip and the rollers after it breaks. Carbon dioxide is typically stored in cylinders. To better monitor the cylinder's weight, the cylinder is typically connected via a bracket to a load cell mounted on the underside of the suspension beam, leaving the bottom of the cylinder suspended in the air. Because the carbon dioxide cylinders used in production workshops typically weigh over 100 pounds, replacing them requires two people. They must slightly lift the cylinder and then remove the pins or bolts between the bracket and the load cell, making replacement inconvenient. Summary of the Invention

Connecting rods 53 are vertically fixed to either side of the fixing ring, and the crossbar is mounted between the upper ends of the two connecting rods. Specifically, the connecting rods are provided with threaded portions at both the upper and lower ends. The lower end of the connecting rod passes through a lug on the side of the fixing ring and is threadedly connected to a nut, while the upper end of the connecting rod passes through the crossbar and is threadedly connected to a nut.

[0021] A clip 54 is fixed to the upper middle portion of the crossbar. The clip has a groove and a latch hole. A lug 71 is fixed to the lower end of a load cell 70, located on the underside of the suspension frame's crossbeam. The clip's groove engages the lug and is connected to the load cell via a bolt 55 passing through the latch hole. An upper lug 72 is fixed to the upper end of the load cell 70, which connects to the connecting component on the underside of the crossbeam via the upper lug.

[0022] In this embodiment, in order to better articulate the boom with the pry plate, a hinge portion 22 is provided at the lower part of the boom, and the hinge portion is provided with a slot 23 that is buckled on the pry plate. The hinge portion is provided with a pin or bolt 24 that passes through the pry plate to achieve articulation with the pry plate.
