Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a lifting device for a winding pressure roller. Background Technology

[0002] The winding pressure roller 5 is used to wind up copper foil. It is typically transported by hoisting. The winding pressure roller 5 consists of a central winding roller and rotating shafts 20 fixedly mounted at both ends of the winding roller. When parked, the rotating shafts 20 at both ends of the winding pressure roller are placed on the support frame 19. (See reference...) Figure 6 and Figure 7 .

[0003] Existing technology requires the use of slings for hoisting the winding pressure roller 5. The slings have hooks at both ends, which are then attached to the pivots 20 at both ends of the winding pressure roller 5. The hooks then pull the sling upwards, lifting the winding pressure roller 5. During hoisting, the winding pressure roller 5 and the sling form a triangular structure, with acute angles between the two hypotenuses of the sling and the base of the triangle (the base of the triangle). Operators need to pad the hypotenuses of the winding pressure roller 5 with foam material to prevent continuous friction between the hypotenuses and the edges of the winding pressure roller 5. This operation is complex, requiring multiple people to work together. Furthermore, when placed on the support frame 19, the pivots 20 at both ends of the winding pressure roller 5 easily press the hooks against the support frame 19, making them difficult to remove and resulting in low hoisting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device for a winding pressure roller, which has the advantages of convenient fixing and easy detachment when lifting the winding pressure roller, effectively solving the problem of low efficiency in lifting winding pressure rollers using slings in the prior art.

[0005] The present invention adopts the following technical solution: a lifting device for a winding pressure roller, including a lifting frame, a hook provided at the lifting end of the lifting frame, a fixing device provided on the hook, the fixing device including a lifting rod, two tie rods hinged to the right end of the lifting rod, a load-bearing rod provided at the bottom end of each tie rod, the fixing device also being provided with an adaptive device, the adaptive device cooperating with the load-bearing rod to fix the winding pressure roller while controlling the distance between the two load-bearing rods according to the diameter of the winding pressure roller.

[0006] Furthermore, the bottom end of each tie rod is rotatably connected to the corresponding load-bearing rod.

[0007] Furthermore, the adaptive device includes a force rod fixedly disposed at the bottom end of the pull rod, and a pressure rod fixedly disposed at the top end of the force rod.

[0008] Furthermore, a stop bar is fixedly installed at the outer end of each pressure bar in the vertical direction.

[0009] Furthermore, a bushing is fixedly installed at the bottom of each tie rod, and the load-bearing rod passes through the bushing and is rotatably connected to the bushing.

[0010] Furthermore, the bottom end of each lever is fixedly mounted to the outer surface of the corresponding bushing.

[0011] Furthermore, the right end of the lifting rod is rotatably connected to a first shaft tube and a second shaft tube, and the outer surfaces of the first shaft tube and the second shaft tube are respectively fixedly set to the corresponding tie rods.

[0012] Furthermore, an end plate is fixedly installed at the left end of the lifting rod.

[0013] Furthermore, the lifting frame includes a base, a support rod is hinged to the upper end of the base, and an angle rod is fixedly installed between the support rod and the base, forming a triangular structure with the base, the angle rod, and the support rod.

[0014] Furthermore, a rotating rod is hinged to the top of the support rod, and the left end of the rotating rod is the lifting end of the lifting frame; a hook is set at the left end of the rotating rod, and a hydraulic telescopic rod is hinged to the outer surface of the support rod, with the output end of the hydraulic telescopic rod hinged to the rotating rod.

[0015] I. This utility model, by setting up a lifting frame, hook, lifting rod, tie rod, load-bearing rod, and adaptive device, allows the winding pressure roller to be placed on two load-bearing rods during use. The lifting frame is then raised via its lifting end, causing the hook to lift the lifting rods. The lifting rods, through the two tie rods, lift the load-bearing rods, which in turn lift the winding pressure roller. Due to the force, the two tie rods rotate, causing their bottom ends to move closer together, which in turn causes the two load-bearing rods to move closer together. Simultaneously, the adaptive device fixes the winding pressure roller. When the adaptive device fixes the winding pressure roller, the two load-bearing rods stop moving closer together. This achieves automatic fixing of the winding pressure roller while the hook lifts it, facilitating operation and convenient fixing and detaching of the winding pressure roller during lifting, thus improving work efficiency.

[0016] II. This utility model, by setting up force bars and pressure bars, allows the winding pressure roller to enter between the pressure bars and the force bars during use. Then, the hook lifts it upwards. When the force bars bear the weight of the winding pressure roller, the bottom ends of the two pull rods move closer together, causing the force bars to drive the pressure bars downwards. When the pressure bars press the winding pressure roller tightly, the bottom ends of the two pull rods stop moving closer together, thus automatically fixing the winding pressure roller. Then, the lifting frame lifts the winding pressure roller to the designated position, places the rotating shafts at both ends of the winding pressure roller on the corresponding support frames, and then adjusts the distance between the two force bars to increase, allowing the force bars to be pulled out to the right; thus completing the lifting of the winding pressure roller. During the lifting of the winding pressure roller, it is convenient to fix the winding pressure roller with the fixing device and to easily remove the fixing device from the winding pressure roller.

Detailed Implementation

[0019] Please see Figure 1-7 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: The lifting device for the winding pressure roller of this utility model includes a lifting frame. A hook 1 is provided at the lifting end of the lifting frame. A fixing device is provided on the hook 1. The fixing device includes a lifting rod 2. Two tie rods 3 are hinged to the right end of the lifting rod 2. A load-bearing rod 4 is provided at the bottom end of each tie rod 3. The fixing device also includes an adaptive device. The adaptive device, in cooperation with the load-bearing rods 4, fixes the winding pressure roller 5 while controlling the spacing between the two load-bearing rods 4 according to the diameter of the winding pressure roller 5. In use, the winding pressure roller 5 is placed on the two load-bearing rods 4, and then the lifting end of the lifting frame is raised, causing the hook 1 to drive the lifting rod 2 upward. The lifting rod 2 drives the load-bearing rod 4 to rise through the two tie rods 3. The two load-bearing rods 4 lift the winding pressure roller 5. Due to the force, the two tie rods 3 rotate, causing their bottom ends to move closer together, which in turn drives the two load-bearing rods 4 to move closer together. As the two load-bearing rods 4 move closer together, they also drive the adaptive device to fix the winding pressure roller 5. When the adaptive device fixes the winding pressure roller 5, the two load-bearing rods 4 stop moving closer together, thus realizing the automatic fixing of the winding pressure roller 5 while the hook 1 lifts it. This facilitates operation, makes it easy to fix and detach the winding pressure roller 5 during hoisting, and improves work efficiency.

[0020] In this embodiment, the bottom end of each pull rod 3 is rotatably connected to the corresponding load-bearing rod 4. In use, when the hook 1 drives the two pull rods 3 to move upward through the lifting rod 2, the two pull rods 3 lift the winding pressure roller 5 through the load-bearing rod 4. At this time, since the load-bearing rod 4 and the pull rod 3 are rotatably connected, the top ends of the two pull rods 3 are simultaneously subjected to an upward pulling force, and they roll against each other through the load-bearing rod 4 and the winding pressure roller 5, making it easier for the bottom ends of the two pull rods 3 to close together; and making it easier to achieve the purpose of the two pull rods 3 driving the adaptive device to fix the winding pressure roller 5.

[0021] In this embodiment, the adaptive device includes a force rod 6 fixedly disposed at the bottom end of the pull rod 3, and a pressure rod 7 fixedly disposed at the top end of the force rod 6.

[0022] In use, the two load-bearing rods 4 are initially spaced at a set distance, allowing the winding pressure roller 5 to enter between the pressure rod 7 and the load-bearing rod 4. Then, the hook 1 lifts it upwards. When the load-bearing rod 4 bears the weight of the winding pressure roller 5, and with the load-bearing rod 4 rotatably connected to the pull rod 3, the bottom ends of the two pull rods 3 move closer together, causing the force rod 6 to drive the pressure rod 7 downwards. When the pressure rod 7 presses the winding pressure roller 5 tightly, the bottom ends of the two pull rods 3 stop moving closer together, thus automatically fixing the winding pressure roller 5. Then, the lifting frame lifts the winding pressure roller 5 to the designated position, places the rotating shafts 20 at both ends of the winding pressure roller 5 on the corresponding support frame 19, and then adjusts the distance between the two load-bearing rods 4 appropriately to increase the distance, allowing the load-bearing rod 4 to be pulled out to the right; thus completing the lifting of the winding pressure roller 5. During the lifting of the winding pressure roller 5, it is convenient to fix the winding pressure roller 5 with the fixing device and to easily remove the fixing device from the winding pressure roller 5.

[0023] In this embodiment, each pressure rod 7 has a stop bar 8 fixedly installed at its outer end in the vertical direction. When in use, after the pressure rod 7 and the load-bearing rod 4 are fixed to the winding pressure roller 5, the stop bar 8 can effectively prevent the winding pressure roller 5 from rolling to the left and falling.

[0024] In this embodiment, a bushing 9 is fixedly provided at the bottom end of each pull rod 3, and the load-bearing rod 4 passes through the bushing 9 and is rotatably connected to the bushing 9; the load-bearing rod 4 is rotatably connected to the pull rod 3 through the bushing 9.

[0025] In this embodiment, the bottom end of each force bar 6 is fixedly set to the outer surface of the corresponding bushing 9; the force bar 6 is fixedly set to the bottom end of the pull rod 3 through the bushing 9.

[0026] In this embodiment, the right end of the lifting rod 2 is rotatably connected to a first shaft tube 10 and a second shaft tube 11. The outer surfaces of the first shaft tube 10 and the second shaft tube 11 are respectively fixedly set to the corresponding tie rods 3. Each tie rod 3 is rotatably connected to the lifting rod 2 through the first shaft tube 10 or the second shaft tube 11, so that the top ends of the two tie rods 3 are hinged to the lifting rod 2.

[0027] In this embodiment, an end plate 12 is fixedly installed at the left end of the lifting rod 2. When the hook 1 hooks the lifting rod 2, the end plate 12 and the first shaft tube 10 limit the hook 1.

[0028] In this embodiment, the lifting frame includes a base 13, with a support rod 14 hinged to the upper end of the base 13. An angle rod 15 is fixedly arranged between the support rod 14 and the base 13. The base 13, the angle rod 15, and the support rod 14 form a triangular structure, making the support rod 14 more stable. A rotating rod 16 is hinged to the top of the support rod 14, and the left end of the rotating rod 16 is the lifting end of the lifting frame. A hook 1 is set at the left end of the rotating rod 16. A hydraulic telescopic rod 17 is hinged to the outer surface of the support rod 14, and the output end of the hydraulic telescopic rod 17 is hinged to the rotating rod 16. In use, the hydraulic telescopic rod 17 extends and retracts, causing the rotating rod 16 to rotate, which raises and lowers the left end of the rotating rod 16. Then, the winding pressure roller 5 is lifted or lowered through the hook 1, the lifting rod 2, the pull rod 3, and the load-bearing rod 4. The lower end of the base 13 is also provided with a movable wheel 18, which is used to move the lifting frame to lift the winding pressure roller 5.

[0029] The working principle of this utility model is as follows: In use, the two load-bearing rods 4 are initially spaced at a predetermined distance, allowing the winding pressure roller 5 to enter between the pressure rod 7 and the load-bearing rod 4. Then, the hydraulic telescopic rod 17 drives the rotating rod 16 to rotate, causing the left end of the rotating rod 16 to rise upwards, thus lifting the load-bearing rod 4 upwards with the hook 1. When the load-bearing rod 4 bears the weight of the winding pressure roller 5, coupled with the rotatable connection between the load-bearing rod 4 and the pull rod 3, the bottom ends of the two pull rods 3 move closer together, causing the force rod 6 to drive the pressure rod 7 downwards. When the pressure rod 7 presses the winding pressure roller 5 tightly... When the roller 5 is in motion, the bottom ends of the two pull rods 3 stop moving closer to each other, thus automatically fixing the winding pressure roller 5. Then, the lifting frame lifts the winding pressure roller 5 to the designated position, places the rotating shafts 20 at both ends of the winding pressure roller 5 on the corresponding support frame 19, and then adjusts the distance between the two load-bearing rods 4 appropriately to increase the distance, so that the load-bearing rods 4 can be pulled out to the right; thus completing the lifting of the winding pressure roller 5. When lifting the winding pressure roller 5, it is convenient to fix the winding pressure roller 5 with the fixing device and to remove the fixing device from the winding pressure roller 5.
