Description

Technical Field

[0001] This utility model relates to the technical field of marine engineering, and in particular to a fixing device for large-diameter steel pipes. Background Technology

[0002] With the development of marine energy, the weight and structural dimensions of marine engineering equipment are constantly breaking records, and the diameter and length of steel pipes are becoming increasingly larger. After steel pipe sections are rolled into shape from steel plates, they need to be joined together section by section, a process known as steel pipe splicing. This is usually done on an I-beam jig. When a steel pipe section is placed on the I-beam, it is usually secured with wooden wedges to prevent it from rolling. However, as the diameter of the steel pipe increases, the center of gravity also rises. Since wooden wedges are relatively light and lack additional fixation, the steel pipe is likely to roll under external disturbances, which can easily lead to accidents. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fixing device for large-diameter steel pipes that is easy to assemble and disassemble and has a stable structure.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes an I-beam steel frame, on which two fixing units are provided. A fixing station is provided between the two fixing units on the I-beam steel frame. Each fixing unit includes a support block, a fixing frame, and two clips. The inner side of the support block is a supporting surface. The fixing frame abuts against the outer side and both sides of the support block. Each of the two clips is provided with a slot and a locking mechanism. One clip is engaged with one side of the fixing frame and the I-beam steel frame through the slot, and the other clip is engaged with the other side of the fixing frame and the I-beam steel frame through the slot. The locking mechanism can lock in the slot.

[0005] Furthermore, the locking mechanism includes a sleeve and a screw, the sleeve is disposed on the clamp, the screw is threadedly connected to the sleeve, and a rotating handle is provided at the end of the screw.

[0006] Furthermore, the locking mechanism is located below the card slot.

[0007] Furthermore, the fixing frame includes a limiting frame and a locking frame. The limiting frame is connected to the inner side of the locking frame, and the limiting frame abuts against the outer side and both sides of the support block. When locked, the clamp abuts against the outer side and upper end face of the locking frame.

[0008] Furthermore, the supporting surface is an inclined surface or a circular arc surface.

[0009] Furthermore, an anti-slip layer is provided on the support surface.

[0010] The beneficial effects of this utility model are:

[0011] In contrast to the shortcomings of existing technologies, in this invention, when a large-diameter steel pipe is placed in a fixed position on an I-beam frame, the two sides of the large-diameter steel pipe are secured by two support blocks to prevent the pipe from rolling. The fixing frame is then nested around the outside of the support blocks, abutting against the outer and two sides of the support blocks. A clamp is inserted through a slot into one side of the fixing frame and the I-beam frame, and another clamp is inserted through a slot into the other side. Finally, a locking mechanism secures the pipe to the I-beam frame. This invention achieves a stable and secure fixation of the support blocks, preventing them from shifting. The fixing bracket abuts against the outer and two sides of the support block, and the locking mechanism secures the bracket to the I-beam frame, ensuring a firm fixation of the two support blocks to the steel pipe. Furthermore, the use of clips and the fixing bracket facilitates easy assembly and disassembly, and allows for repeated use. Additionally, the fixing device fits well onto the I-beam frame, making operation convenient. These features contribute to the advantages of easy assembly and disassembly and a stable structure.

[0022] like Figures 1 to 3 As shown, in this embodiment, the present invention includes an I-beam frame 1, on which two fixing units 2 are provided. A fixing station 3 is located between the two fixing units 2 on the I-beam frame 1. Each fixing unit 2 includes a support block 5, a fixing frame 6, and two clips 8. The inner side of the support block 5 is a supporting surface 7. The fixing frame 6 abuts against the outer side and both sides of the support block 5. Each of the two clips 8 is provided with a slot 9 and a locking mechanism 10. One clip 8 is engaged with one side of the fixing frame 6 and the I-beam frame 1 through the slot 9, and the other clip 8 is engaged with the other side of the fixing frame 6 and the I-beam frame 1 through the slot 9. The locking mechanism 10 can lock the clips in the slot 9. The support block 5 can be a wooden wedge; each fixing unit 2 has two clips 8.

[0023] In contrast to the shortcomings of existing technologies, in this invention, when a large-diameter steel pipe is placed on the fixed position 3 of the I-beam frame 1, the two sides of the large-diameter steel pipe are secured by two support blocks 5 to prevent the pipe from rolling. Furthermore, a fixing frame 6 is nested outside the support blocks 5, so that the fixing frame 6 abuts against the outer and two sides of the support blocks 5. A clip 8 is inserted through a slot 9 into one side of the fixing frame 6 and the I-beam frame 1, and another clip 8 is inserted through a slot 9 into the other side of the fixing frame 6 and the I-beam frame 1. Finally, a locking mechanism 10 locks the pipe securely to the I-beam frame. On the frame 1, the support block 5 is firmly fixed and not easily moved. Therefore, the present invention can make the two support blocks 5 firmly fixed to the steel pipe by means of the fixing frame 6 abutting against the outer side and both sides of the support block 5 and locking the fixing frame 6 on the I-beam frame 1 by means of the locking mechanism 10. Secondly, the support block 5 is fixed by means of the clip 8 and the fixing frame 6, which can be easily disassembled and reused. In addition, the fixing device can be well adapted to the I-beam frame 1 and is easy to operate, so the present invention has the advantages of easy disassembly and assembly and structural stability.

[0024] In some embodiments, the locking mechanism 10 includes a sleeve 11 and a screw 12. The sleeve 11 is disposed on the clamp 8, and the screw 12 is threaded into the sleeve 11. A rotating handle 13 is provided at the end of the screw 12. Specifically, by rotating the handle 13, the screw 12 can extend and retract along the sleeve 11 to achieve locking between the fixing frame and the I-beam frame 1. This locking method is easy to operate and has a simple structure.

[0025] In some embodiments, the locking mechanism 10 is located below the slot 9. Specifically, when locking, the locking end of the locking mechanism 10 can be locked onto the I-beam frame 1 from bottom to top, so that the I-beam frame 1 and the fixing frame can be locked in the slot 9.

[0026] In some embodiments, the fixing frame 6 includes a limiting frame 15 and a locking frame 16. The limiting frame 15 is connected to the inner side of the locking frame 16, and the limiting frame 15 abuts against the outer side and both sides of the support block 5. The clamp 8 abuts against the outer side and upper end face of the locking frame 16 when locked. Specifically, the fixing frame 6 is welded from multiple angle steels or steel plates, and its size is determined according to the support block 5. The fixing frame 6 can be nested on the outside of the support block 5.

[0027] In some embodiments, the support surface 7 is an inclined surface or an arc surface; an anti-slip layer is provided on the support surface 7. Specifically, by making the support surface 7 an inclined surface or an arc surface, the steel pipe can be well supported; moreover, the anti-slip layer can increase the friction between the support surface 7 and the steel pipe, which can prevent the steel pipe from rolling out of the fixed position 3.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
