Description

Technical Field

[0001] This utility model relates to a device for disassembling and replacing carbon dioxide cylinders. Background Technology

[0002] In the aluminum strip manufacturing process, carbon dioxide is often used for cooling and isolating the strip from oxygen in the air to prevent sparks from generated by friction between the strip and the rolls after it breaks. Carbon dioxide is typically stored in carbon dioxide cylinders. To better monitor the weight of these cylinders, they are usually connected to a load cell mounted on the underside of a suspension beam via a hanger, leaving the bottom of the cylinder suspended. Since the carbon dioxide cylinders used in production workshops typically weigh between 100 and 200 kilograms, replacing them requires two people to lift the cylinder slightly and then remove the pins or bolts between the hanger and the load cell, making the replacement operation inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a device for disassembling and replacing carbon dioxide cylinders. This device helps to lift the carbon dioxide cylinders, making it easier to disassemble and replace them.

[0004] The technical solution of this utility model is as follows: a carbon dioxide cylinder disassembly and replacement device, including a pry plate, the upper front end of the pry plate having a notch for embedding a hanging crossbar fixed to the top of the carbon dioxide cylinder, a hanging rod hinged to the pry plate at the rear side of the notch, and a hook for hooking the suspension beam of the carbon dioxide cylinder at the upper end of the hanging rod.

[0005] Furthermore, the bracket includes a fixing ring fixedly connected to the top of the carbon dioxide cylinder, with connecting rods vertically fixed on both sides of the fixing ring, and a crossbar installed between the upper ends of the two connecting rods. A buckle is fixed on the upper middle part of the crossbar for connecting to a weighing sensor installed on the lower side of the crossbeam of the suspension bracket.

[0006] Furthermore, the lower part of the boom is provided with a hinge portion, the hinge portion is provided with a slot for fastening onto the pry plate, and the hinge portion is provided with a pin that passes through the pry plate and is hinged to the pry plate.

[0007] Furthermore, the lower end of the boom is screwed to the hinge.

[0008] Furthermore, a handle is provided at the rear of the pry bar.

[0023] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0024] refer to Figures 1 to 7

[0025] A carbon dioxide cylinder disassembly and replacement device includes a pry bar 10. A notch 11 is provided at the upper front end of the pry bar for embedding a crossbar 51 of a hanger 50 fixed to the top of a carbon dioxide cylinder 40. A lifting rod 20 is hinged to the rear side of the notch on the pry bar. A hook 21 is provided at the upper end of the lifting rod for hooking onto the crossbeam 61 of a suspension frame 60 for the carbon dioxide cylinder. By pressing down on the rear of the pry bar, the carbon dioxide cylinder is lifted upwards a certain distance, allowing it to be disassembled from the load cell on the crossbeam of the suspension frame.

[0026] In this embodiment, in order to better lift the carbon dioxide cylinder and reduce the force required to lower the pry bar, a bracket 30 is also provided. The bracket includes a support plate 31 for inserting into the bottom of the carbon dioxide cylinder. A pressure rod 32 is fixedly inclined on the support plate, and a handle 33 is fixed laterally at the upper end of the pressure rod.

[0027] In this embodiment, the hanger on the carbon dioxide cylinder includes a fixing ring 52 that is fixedly connected to the constricted portion at the top of the carbon dioxide cylinder. This fixing connection can be a screw connection. Connecting rods 53 are vertically fixed to both sides of the fixing ring, and a crossbar is installed between the upper ends of the two connecting rods. Specifically, both the upper and lower ends of the connecting rods are provided with threaded portions, and the lower end of the connecting rod passes through the lug on the side of the fixing ring and is screwed with a nut, while the upper end of the connecting rod passes through the crossbar and is screwed with a nut.

[0028] A fastener 54 is fixed to the upper middle part of the aforementioned crossbar. The fastener has a groove and a pin hole. A lifting lug 71 is fixed to the lower end of a load cell 70 located on the lower side of the crossbeam of the suspension frame, so that the groove of the fastener can be fastened onto the lifting lug, and the load cell can be connected via a pin or bolt 55 passing through the pin hole. An upper lifting lug 72 is fixed to the upper end of the load cell 70, and the load cell is connected to the connecting component on the lower side of the crossbeam via the upper lifting lug.

[0029] In this embodiment, in order to better hinge the boom to the pry plate, the lower part of the boom is provided with a hinge part 22, the hinge part is provided with a slot 23 for fastening to the pry plate, and the hinge part is provided with a pin or bolt 24 that passes through the pry plate and hinges to the pry plate.

[0030] In this embodiment, the lower end of the boom is screwed to the hinge.

[0031] In this embodiment, the rear of the pry bar is provided with a grip handle 12 with a rubber layer for better gripping.

[0032] In this embodiment, the pry bar and the lifting rod are both made of metal, which helps to ensure strength.

[0033] In this embodiment, the support plate, pressure bar, and handle are all made of metal, which helps to ensure strength.

[0034] In use, first hang the hook of the boom on the crossbeam of the suspension frame, and snap the notch of the pry bar into the crossbeam of the bracket; then insert the bracket plate into the bottom of the carbon dioxide cylinder, and use the handle on the pressure rod to press down to lift the carbon dioxide cylinder a certain distance, so that the pin on the fastener is in a no-load state; then press down the rear end of the pry bar with one hand to keep the carbon dioxide cylinder in a lifted state. At this time, there is no need to continue to apply force to the bracket, and the lever principle can reduce the required downward force; remove the pin or bolt from the fastener, and one person can complete the disassembly of the carbon dioxide cylinder and the load cell; finally, lift the rear end of the pry bar (without applying force to the pry bar) so that the bottom end of the carbon dioxide cylinder contacts the base plate of the suspension frame.

[0035] When installing a carbon dioxide cylinder, use a pry bar and bracket to lift it. Then, pass the pin or bolt through the pin hole of the fastener and lock it in place to complete the installation. Note that when using the bracket to lift the cylinder, the hook of the lifting rod must be pre-attached to the crossbeam, the notch of the pry bar must be aligned with the crossbeam, and the cylinder must be kept from tilting. Alternatively, loosen the nut at the top of the connecting rod to adjust its effective connection length, raising the crossbeam so that the fastener can connect to the load cell's lifting lug. Then, tighten the nut at the top of the connecting rod to detach the bottom of the carbon dioxide cylinder from the base plate of the suspension frame.

[0036] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0037] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0038] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0039] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
