Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, in particular to a hoisting device for a side plate of a graphitizing furnace. Background Art

[0002] The side panels of graphitization furnaces are usually made of heat-resistant materials and can withstand high-temperature environments. To improve the convenience of construction and maintenance, the side panels of graphitization furnaces usually adopt a modular design. After being manufactured in the factory, they can be transported to the project site for direct assembly. This can significantly reduce the workload on the construction site and shorten the construction period.

[0003] Because side panels frequently break, deform, and fall out of column slots during use, they require frequent lifting and replacement. Traditionally, graphitization furnace side panels are hoisted using an overhead crane, which is connected to the crane via hooks. However, since only two overhead cranes are typically installed on top of a furnace area (including twelve graphitization furnaces), only two side panels can be hoisted simultaneously. Furthermore, the lack of dedicated lifting equipment for existing side panel hoisting systems results in extremely low efficiency. Therefore, a device for rapidly lifting graphitization furnace side panels is urgently needed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a graphitization furnace side plate hoisting device to meet the demand for rapid graphitization furnace side plate hoisting.

[0006] A first fixed pulley is installed at the same height as the winch output end on the left side of the vertical frame, and a second fixed pulley is installed at the bottom of the right end of the horizontal frame. The steel rope at the winch output end passes around the first fixed pulley, the second fixed pulley, and the pulley block in sequence.

[0007] The top of the hoisting rod is provided with three steel ropes distributed equidistantly from the center to both ends. The top ends of the three steel ropes are connected to the lifting rings corresponding to the central steel rope, and the lifting rings are connected to the hooks at the bottom of the pulley block.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1

[0018] In order to quickly lift the side plate of the graphitization furnace and replace it quickly. Figures 1 to 2 As shown, a graphitization furnace side plate hoisting device includes a winch 1, which is installed on a base 2 as a power machine. A vertical frame 3 is connected upward to the right side of the base 2, and a horizontal frame 4 is connected horizontally to the left of the vertical frame 3, forming the main frame of the hoisting device.

[0019] A first fixed pulley 6 is installed on the left side of the vertical frame 3 at the same height as the output end of the winch 1, a second fixed pulley 7 is installed at the bottom of the right end of the horizontal frame 4, and a pulley group 8 is installed at the bottom of the left end of the horizontal frame 4; a steel rope 5 is connected to the output end of the winch 1, and the steel rope 5 passes around the first fixed pulley 6, the second fixed pulley 7, and the pulley group 8 in sequence; the stability of the transmission process is increased, and the working load of the winch 1 is reduced under the setting of the pulley group 8, thereby extending its working life.

[0020] A lifting rod 9 is connected under the pulley block 8. Three steel ropes 5 are arranged on the top of the lifting rod 9, which are evenly distributed from the center to both ends. The top ends of the three steel ropes 5 are connected to the lifting rings 10 corresponding to the central steel rope 5. The lifting rings 10 are connected to the hooks at the bottom of the pulley block 8; this makes the lifting rod 9 more stable during the lifting process and can evenly bear the lifting load.

[0021] Three slings 11 are connected to the lifting rod 9 via steel cables 5. These slings can lift three side panels at once, improving lifting efficiency. These slings 11 are designed in an inverted U-shape to facilitate gripping the side panels of the graphitizer. Hexagonal bolts 12 are threaded onto the sides of these slings 11. Specifically, one hexagonal bolt 12 is located at the upper center of the side of the sling 11, and four hexagonal bolts 12 are symmetrically positioned about the center of the sling 11. Tightening these hexagonal bolts 12 secures the side panels, ensuring they remain securely in place and prevents them from slipping or shifting during the lifting process.

[0022] When in use, first align and combine the three hangers 11 with the side panels of the graphitization furnace, and tighten the hexagonal bolts 12 to fix the clamping side panels. Then start the winch 1, which drives the lifting rod 9 and the hanger 11 up or down through the steel rope 5 and the pulley block 8, thereby realizing the rapid lifting and replacement of the side panels of the graphitization furnace. The lifting device has a simple structure, is easy to operate, and has high lifting efficiency. Through the cooperation of the winch 1 and the pulley block 8, the rapid lifting and replacement of the side panels of the graphitization furnace can be easily achieved, greatly improving work efficiency and safety. At the same time, a plurality of special hangers 11 are provided, which can lift multiple side panels at a time, thereby improving the efficiency of lifting. In addition, the inverted U-shaped design of the hanger 11 and the fixing method of the hexagonal bolts 12 also ensure the stability and reliability of the lifting.

[0023] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the content of this specification.
