[0045] This utility model proposes a mold cover lifting device for assisting in the daily maintenance process of a pellet mill. The structure of the lifting bracket 1, lifting device 2, and lifting support module 3 in this utility model is particularly suitable for lifting the mold cover during pellet mill maintenance.

[0046] In general, the molded cover lifting device proposed in this utility model mainly includes: a lifting bracket 1, a lifting device 2, and a lifting support module 3. See also... Figure 1 It shows the arrangement of the lifting bracket 1, the lifting device 2, and the lifting support module 3.

[0047] The mold cover lifting device proposed in this utility model allows technicians to quickly replace the mold cover during frequent routine maintenance of the pellet mill. Technicians only need to control a crane to move the mold cover lifting device to one side of the pellet mill, place the hook 29 against the inner wall of the mold cover, and control the electric hoist 36 to tighten the wire rope 39. This provides an upward pulling force to the mold cover before it is disassembled. Then, the connecting parts of the mold cover installed on the pellet mill can be directly removed. Finally, the crane is controlled to move the mold cover to the cleaning station, achieving rapid mold cover replacement. Furthermore, the entire disassembly and transportation process can be completed by only one person, improving maintenance efficiency.

[0048] The lifting bracket 1 has a balance plate 11 installed on its left and right sides. The balance plates 11 are connected by bolts to the front and rear sides of each other. A pair of support arms 12 are provided between the pair of support arms 12.

[0049] The aforementioned lifting device 2 is located directly below the center of the lifting support 1. The lifting device 2 includes: a molding cover lifting head 21, a pulley 24, a connecting hole 25, a round pin 26, a lock 27, a butterfly buckle 28, and a hook 29. The molding cover lifting head 21 is located directly below the gap 13. The top of the molding cover lifting head 21 is U-shaped. A bushing 22 is fitted in the center of the molding cover lifting head 21. The bushing 22 abuts against the inner wall of the molding cover lifting head 21 on both its front and rear sides. A connecting block 23 is provided at the bottom of the molding cover lifting head 21. A pulley 24 is fitted with an interference fit on the outside of the bushing 22. A connecting hole 25 is opened in the center of the top of the molding cover lifting head 21. One side of the round pin 26 abuts against the front outer wall of the molding cover lifting head 21, and the other side of the round pin 26 is fitted with a connecting block. Hole 25 protrudes from the rear side of the lifting head 21 of the molding cover. The round pin 26 is fitted into the bushing 22 with a clearance fit. The lock 27 is connected to the connecting block 23 by bolts. The butterfly buckle 28 is fastened in the lock 27. During the lifting process, after the hook 29 is pulled up against the inner wall of the molding cover, the left and right sides of the molding cover are different in weight. The cover tilts and adapts to become balanced with the hook 29 as the center point. The butterfly buckle 28 can improve the mobility of the chain 210 on the lock 27. If the chain 210 is directly connected to the lock 27, the range of motion of the chain 210 is low, and the molding cover cannot be kept balanced during the lifting process. The chain 210 is fastened to the bottom of the butterfly buckle 28, and the hook 29 is fastened to the bottom of the butterfly buckle 28 by a pin.

[0050] The aforementioned hoisting support module 3 is bolted to the mounting balance plate 11 on both sides. The bottom of the hoisting support module 3 is secured to the top of the hoisting device 2. The hoisting support module 3 includes: a reinforcing plate 31, a mounting partition 33, a mounting shaft 34, rollers 35, an electric hoist 36, an arc-shaped guide cover 37, a positioning connecting plate 38, and a wire rope 39. The reinforcing plate 31 is bolted to the top left side of the reinforcing plate 31. A reinforcing rib is provided between the reinforcing plate 31 and the mounting balance plate 11, which improves the support force on the granulator. The bottom of the reinforcing plate 31 and the mounting balance plate 11 has a clearance rope groove 32. The mounting partition 33 is located around the interval 13 and is bolted to the inner wall of the reinforcing plate 31. The mounting shaft 34 passes through the mounting partition 33 on the left side of the hoisting bracket 1. The rollers 35 are located on the left side of the interval 13. Roller 35 is mounted on mounting shaft 34. Electric hoist 36 is bolted to balance plate 11 on the left side of lifting bracket 1. Arc-shaped guide cover 37 is welded to the center of mounting partition 33 on the right side of lifting bracket 1. Positioning connecting plate 38 is located on the side of arc-shaped guide cover 37 away from electric hoist 36. Positioning connecting plate 38 is bolted to mounting partition 33. One side of wire rope 39 is bolted to positioning connecting plate 38. The other side of wire rope 39 is first wrapped around the outside of arc-shaped guide cover 37, then wrapped downwards around the bottom of pulley 24, then wrapped upwards around the top of roller 35, and then passed downwards through clearance rope groove 32 and wound around electric hoist 36. Lifting support module 3 can apply a certain upward pressure to the pressing mold cover by tightening wire rope 39 when the pressing mold cover is not disassembled. In this way, the pressing mold cover will not fall off or deform when the connecting parts on the pressing mold cover are removed.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
