Technical Field
[0001] This utility model relates to the field of sheet metal hoisting technology, and in particular to an auxiliary device for hoisting large sheet metal parts that is easy to handle. Background Technology
[0002] Large sheet metal lifting auxiliary devices are specialized auxiliary equipment designed for lifting and transporting large sheet metal parts. They achieve stable fixation and balanced force distribution of sheet metal parts, improve the safety and efficiency of lifting operations, and reduce the difficulty of manual operation. They are widely used in the sheet metal handling process in industries such as machinery manufacturing, automobile production, and construction machinery, and are key auxiliary tools to ensure the quality of large sheet metal part transport and operational safety.
[0003] The large sheet metal lifting auxiliary device is based on the concept of balanced force and stable clamping. By adapting to the sheet metal adsorption components or support frame, it accurately fits the surface of the workpiece and forms a reliable fixation. Depending on the material, shape and weight of the sheet metal part, the device uses adjustable claws of mechanical clamping to bite the edge of the workpiece, or vacuum adsorption components to generate negative pressure to adsorb the surface, or multi-point support structure to distribute the force points, so as to achieve uniform transmission of lifting force and avoid local stress concentration that could cause workpiece deformation. At the same time, through the rigid support and adaptive adjustment of the mechanical structure, the lifting force is safely transmitted to the load-bearing part of the workpiece, ultimately achieving stable, safe and damage-free lifting and transportation of large sheet metal parts.
[0004] Mechanical clamping devices have limited adaptability and cannot meet the hoisting needs of irregularly shaped or oversized sheet metal parts. The hoisting point positions are mostly fixed and cannot be dynamically adjusted to cope with the center of gravity shift. Relying on manual adjustment is inefficient and lacks precision, making it difficult to quickly adapt to workpieces of different specifications. Some devices have insufficient traction rope load-bearing capacity, posing safety hazards. Therefore, a large sheet metal part hoisting auxiliary device that is easy to handle is proposed to solve the above problems. Utility Model Content

It aims to improve the problems of limited adaptability of existing clamping devices, which make it difficult to meet the lifting needs of irregularly shaped or extra-large sheet metal parts, and the insufficient load-bearing capacity of the traction ropes of some devices, which pose safety hazards.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A lifting auxiliary device for large sheet metal parts that is easy to handle includes a frame, with clamping mechanisms slidably connected to both ends of the frame, multiple connecting mechanisms fixedly connected to the top of the frame, outer rods fixedly connected to both sides of the frame, and connecting ropes fixedly connected to the top of the frame.

As a further description of the above technical solution: The limiting component includes an operating block, one end of which is fixedly connected to the outside of a fixed block, a fixed rod is slidably connected to the side of the operating block, and a moving rod is rotatably connected to one end of the fixed rod. As a further description of the above technical solution: The operating block is externally slidably connected to the outside of the square slot, the fixed rod is fixedly connected to the outside of the fixed block, and the moving rod is slidably connected to the outside of the fixed block.

[0007] This utility model has the following beneficial effects: 1. In this utility model, a fixing block is fixedly connected to the outer rod. By pressing down the operating block fixed to the outside of the movable column connected to the square groove on the fixing block, the movable column will press down the bottom plate connected to the square block into the groove on the inner rod inside the outer rod for fixing. At this time, the operating block fixed to the outside of the movable column is fixed by the fixing rod and the moving rod of the limiting component, which solves the problem that the mechanical clamping adaptability is limited and it is difficult to meet the hoisting needs of irregular shapes or extra-large sheet metal parts.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0012] A lifting auxiliary device for large sheet metal parts that is easy to handle, referring to Figures 1 to 3 The system includes a frame 1, with clamping mechanisms 2 slidably mounted at both ends for securely holding sheet metal parts. Multiple connecting mechanisms 3 for connecting hoisting equipment are fixedly connected to the top, and outer rods 4 are fixedly installed on both sides. A connecting rope 5 for auxiliary force support is also fixedly connected to the top of the frame 1. The clamping mechanism 2 consists of a fixed block 21, a square groove 22, a movable column 23, a square block 24, a base plate 25, a fixed column 26, an inner rod 27, and a limiting component 28. The fixed block 21 is fixed to one end of the frame 1, and the movable column 23 is rotatably connected within the square groove 22 at its top. The bottom of the moving column 23 is slidably connected to the square block 24. The bottom of the square block 24 is fixed to the base plate 25. The top of the base plate 25 is provided with two fixed columns 26 and slidably engaged with the inner rod 27. The limiting component 28 is composed of an operating block 281, a fixed rod 282 and a moving rod 283. One end of the operating block 281 is fixed to the outside of the fixed block 21, and the side is slidably connected to the fixed rod 282. One end of the fixed rod 282 is rotatably connected to the moving rod 283. The operating block 281 slides against the outside of the square groove 22. Both the fixed rod 282 and the moving rod 283 are slidably engaged with the outside of the fixed block 21. Specifically, for large sheet metal parts of different specifications and sizes, the frame 1 adapts to the handling requirements through the adjustable clamping mechanism 2. After adjusting to the required size, the fixing block 21 fixed on the outer rod 4 presses down the operating block 281 outside the movable column 23 in the square groove 22, so that the movable column 23 drives the bottom plate 25 connected by the square block 24 to press down into the groove corresponding to the inner rod 27 inside the outer rod 4. Then, the fixing rod 282 of the limiting component 28 and the moving rod 283 are used to lock the operating block 281, so as to achieve a stable clamping of the sheet metal parts. When it is necessary to release the fixation, the moving rod 283 is removed, and the operating block 281 is pulled to drive the movable column 23 to rotate in the opposite direction. The square block 24 and the bottom plate 25 at the bottom of the movable column 23 will be released from the groove on the inner rod 27 along with the fixing column 26, thereby releasing the clamping restriction on the sheet metal parts and completing the hoisting, handling or unloading operation.
[0013] Reference Figure 2 and Figure 4The connecting mechanism 3 specifically includes a circular groove 31 opened on the outside of the frame 1. A cylinder 32 is fixedly installed inside the circular groove 31. An inner groove 33 is opened at the end of the cylinder 32 away from the frame 1. A limiting rod 34 is rotatably connected inside the inner groove 33. The other end of the limiting rod 34 is fixedly connected to the connecting column 35. The end of the connecting column 35 away from the limiting rod 34 is fixedly connected to the other end of the connecting rope 5, and this end is slidably engaged with the end of the cylinder 32 away from the frame 1. The outside of the limiting rod 34 is rotatably connected to the inside of the cylinder 32. At the same time, the outside of the cylinder 32, the outside of the connecting column 35, and the inside of the outer ring 36 are all provided with matching threads 37. The outer ring 36 is both threadedly connected to the outside of the cylinder 32 and slidably fitted to the outside of the circular groove 31. Specifically, the cylinder 32 is pre-fixed in the circular groove 31 of the frame 1. When a stable connection between the frame 1 and the connecting rope 5 is required, the limiting rod 34 fixed at one end of the connecting column 35 is first inserted into the inner groove 33 of the cylinder 32. Then, the connecting column 35 is twisted to drive the limiting rod 34 to rotate in the inner groove 33, so that the limiting rod 34 and the inside of the cylinder 32 form a snap-fit fixation, and the connection between the connecting column 35 and the cylinder 32 is initially completed. Then, the outer ring 36 is fitted onto the connection between the cylinder 32 and the connecting column 35, and the threads 37 of the three are used to tighten the threads, so that the outer ring 36 fits tightly against the outside of the circular groove 31, further strengthening the connection stability between the cylinder 32 and the connecting column 35, ensuring that the connecting rope 5 and the frame 1 are firmly connected during the hoisting process and preventing it from falling off.
[0014] Reference Figure 1 and Figure 3 The outer rod 4 serves as a lateral support component of the device, forming a suitable sliding space inside. The inner rod 27 is slidably assembled inside the outer rod 4, providing basic guidance for the adjustment of the clamping mechanism 2. At the same time, the outer walls of the square block 24, the base plate 25, and the movable column 23 in the clamping mechanism 2 all maintain a sliding fit with the interior of the outer rod 4. The sliding of the square block 24 and the base plate 25 along the interior of the outer rod 4 can adapt to the clamping requirements of sheet metal parts of different sizes. The sliding of the outer wall of the movable column 23 provides a stable trajectory for it to drive the bottom component to press down and fix or reverse reset, ensuring that the movement of each component is smooth and the connection is precise during the adjustment and clamping process, thereby improving the overall operational stability of the device. Specifically, the outer rod 4 is a lateral support component, and the inner rod 27 is slidably assembled inside it and forms a sliding fit with the square block 24, the base plate 25 and the outer wall of the movable column 23 of the clamping mechanism 2. This provides guidance for clamping and adjustment, ensures smooth movement of the components, and improves the stability of the device.
[0015] The implementation principle of this application embodiment is as follows: According to the different sizes of large sheet metal parts, the frame 1 needs to be equipped with an adjustable clamping mechanism 2 to transport sheet metal parts of different specifications and sizes. When the required size is adjusted, a fixing block 21 is fixedly connected to the outer rod 4. By pressing down the operating block 281 fixed outside the movable column 23 connected inside the square groove 22 on the fixing block 21, the movable column 23 will press down the bottom plate 25 connected by the square block 24 into the groove on the inner rod 27 inside the outer rod 4 for fixing. At this time, the operating block 281 fixed outside the movable column 23 is locked with the moving rod 283 by the fixing rod 282 of the limiting component 28. When the fixation is released, the moving rod 283 is removed, and the operating block 281 is pulled to drive the movable column 23 to rotate in the opposite direction. At this time, the square block 24 and the bottom plate 25 pressed down at the bottom of the movable column 23 will be released from the groove on the inner rod 27 along with the fixing column 26.
[0016] The connecting rope 5 connected by buckles on the frame 1 is prone to breakage. Therefore, a connecting mechanism 3 is set at the connection between the frame 1 and the connecting rope 5 to replace the buckle. The cylinder 32 is fixedly connected in the circular groove 31 opened on the frame 1. The other end of the cylinder 32 has an inner groove 33. One end of the connecting column 35 is fixedly connected to the connecting rope 5, and the other end is fixedly connected to the limiting rod 34. When connecting the frame 1 and the connecting rope 5, the limiting rod 34 on the connecting column 35 is inserted into the inner groove 33 inside the cylinder 32, and then twisted to make the limiting rod 34 stuck inside the cylinder 32 for fixation. At this time, the outer ring 36 is used to reinforce the cylinder 32 and the connecting column 35 at the connection of the cylinder 32 and the connecting column 35 through the threaded connection of the external thread 37.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
