Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically to a highly stable transportation structure for large sheet metal parts. Background Technology

[0002] Large sheet metal parts are made by comprehensively cold-working thin metal sheets using sheet metal technology. They are characterized by large dimensions, complex shapes, and high forming precision requirements, and are widely used in automobile manufacturing, aerospace, machinery and equipment, electronic products and other fields.

[0003] Existing large sheet metal parts transportation equipment does not demonstrate significant stability in use. In traditional transportation methods, sheet metal parts are often randomly placed on carpeted floors, occupying a large amount of factory space when stored in large quantities, resulting in serious waste of space resources. For example, in sheet metal manufacturing workshops and machine tool assembly workshops, sheet metal parts are placed separately, which not only takes up space but also affects the overall layout of the workshop and operational efficiency. Some transportation equipment lacks effective cushioning and protection measures during transportation, making sheet metal parts easily damaged when subjected to vibration or collision. For example, when transported on bumpy roads, sheet metal parts may deform or scratch due to lack of cushioning, which will greatly reduce the stability of sheet metal parts transportation.

[0004] Therefore, it is necessary to invent a highly stable transportation structure for large sheet metal parts to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable transport structure for large sheet metal parts, in order to solve the problem of insignificant stability during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable transport structure for large sheet metal parts, comprising a main transport frame, side adjustment frames, tie rods, a base plate, a fixed frame, a folding frame, casters, and a docking mounting seat. Side adjustment frames are provided on both sides of the main transport frame, and tie rods are installed at the ends of the side adjustment frames. A base plate is provided on the surface of the main transport frame and the side adjustment frames. A fixed frame is fixedly provided on one edge of the surface of the main transport frame, and a folding frame is hinged to the other edge of the surface of the main transport frame. Casters are installed on both sides of the bottom surface of the main transport frame and the side adjustment frames. A docking mounting seat is provided in the middle of one side of the outer wall of the main transport frame.

[0007] Preferably, there are two main transport frames, with a support rod intersecting between the two main transport frames. Both ends of the two main transport frames are open, and one end of the side adjustment frame passes through the end of the main transport frame.

[0008] Preferably, bolts are installed through the main transport frame on both sides and in the middle, and mounting holes matching the threads of the bolts are opened on both sides and in the middle of the side adjustment frame. The bolts are fixed from the top surface of the main transport frame into the mounting holes on the surface of the side adjustment frame.

[0009] Preferably, the length of the base plate matches the length of the side adjustment frame after both ends of the autonomous transport frame are pulled out and fixed. Anti-detachment blocks are fixedly provided at the four corners of the surface of the base plate, and the anti-detachment blocks are L-shaped and fit the four corners of the surface of the base plate.

[0010] Preferably, a cover plate is hinged to the top of the fixed frame, and the cover plate is located directly above the main transport frame.

[0011] Preferably, the bottom surface of the cover plate is fixedly provided with inserts on both sides, the inserts are located in slots, and the slots are respectively opened on the top two sides of the folding frame.

[0012] Preferably, two airbag shock absorbers are provided on one side of the docking mounting base. The airbag shock absorbers are located at the middle of the bottom surface of the two main transport frames, and the bottom end of the airbag shock absorbers is not in contact with the bottom surface.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This highly stable transport structure for large sheet metal parts allows for sliding along the end opening of the main transport frame via a side adjustment bracket.

[0022] This utility model provides, for example Figure 1-4 The large sheet metal part high stability transportation structure shown includes a main transport frame 1, a side adjustment frame 2 and a tie rod 3. There are two main transport frames 1, and a support rod is arranged crosswise between the two main transport frames 1. The two ends of the two main transport frames 1 are open. One end of the side adjustment frame 2 passes through the end of the main transport frame 1. The two sides and the middle of the surface of the main transport frame 1 are all fitted with bolts 101. The two sides and the middle of the surface of the side adjustment frame 2 are all provided with mounting holes 102 that match the threads of the bolts 101. The bolts 101 pass through the top surface of the main transport frame 1 and are fixed to the mounting holes 102 on the surface of the side adjustment frame 2. The side adjustment frames 2 are provided on both sides of the main transport frame 1, and the end of the side adjustment frame 2 is fitted with a tie rod 3.

[0023] The main transport frame 1 and the side adjustment frame 2 are provided with a base plate 4. The length of the base plate 4 matches the length of the side adjustment frame 2 after it is pulled out and fixed at both ends of the main transport frame 1. Anti-detachment blocks 401 are fixedly installed at the four corners of the surface of the base plate 4. The anti-detachment blocks 401 are L-shaped and fit against the four corners of the surface of the base plate 4. A fixing frame 5 is fixedly installed on one edge of the surface of the main transport frame 1. A cover plate 501 is hinged to the top of the fixing frame 5. The cover plate 501 is located directly above the main transport frame 1. Insert blocks 50 are fixedly installed on both sides of the bottom surface of the cover plate 501. 2. The insert block 502 is located in the slot 503, and the slot 503 is respectively opened on both sides of the top of the folding frame 6. The folding frame 6 is hinged to the other edge of the surface of the main transport frame 1. The main transport frame 1 and the side adjustment frame 2 are both equipped with casters 7 on both sides of the bottom surface. The main transport frame 1 is provided with a docking mounting seat 8 in the middle of one side of the outer wall. Two airbag shock absorbers 801 are provided on one side of the docking mounting seat 8. The airbag shock absorbers 801 are respectively located in the middle of the bottom surface of the two main transport frames 1. The bottom end of the airbag shock absorber 801 is not in contact with the bottom surface.

[0024] The airbag shock absorber 801 mentioned above is an existing technology product, and its specific structure and function will not be described in detail here.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-4For this type of high-stability transport structure for large sheet metal parts, during use, the two main transport frames 1 first form a basic frame through cross support rods. The side adjustment frame 2 can slide and extend along the end opening of the main transport frame 1. Different lengths are fixed by the threaded engagement of the bolt body 101 and the mounting hole 102 to adapt to sheet metal parts of different sizes. The base plate 4 is replaced synchronously with the side adjustment frame 2, and its length always matches the adjusted total length. The L-shaped anti-detachment block 401 engages with the edge of the sheet metal part to prevent it from sliding back and forth during transport. After the folding frame 6 is unfolded, it forms a closed enclosure with the fixed frame 5. The cover plate 501 is fixed by inserting the insert block 502 into the slot 503 at the top of the folding frame 6 to restrain the top of the sheet metal part. The sheet metal part has a degree of freedom. Its own weight presses the base plate 4, and the cover plate 501 presses down to form a two-way clamp. The L-shaped structure of the anti-detachment block 401 restricts free movement. The pull rod 3 connects to the ends of the two side adjustment frames 2 and is used to adjust the length of the side adjustment frames 2. Two airbag shock absorbers 801 are respectively installed in the middle of the bottom surface of the main transport frame 1. They use the nonlinear stiffness characteristics of air springs to absorb low-frequency large-amplitude vibrations and reduce the transmission of high-frequency micro-vibrations. The bottom end of the airbag shock absorber 801 is suspended to avoid interference with the ground and ensure sufficient shock absorption stroke. The docking mounting seat 8 is set to dock with external pushing equipment, which can push and transport the workpiece after it is placed through the connection of external equipment.
