Description

Technical Field

[0001] This utility model relates to the field of welding double-hook box beams, specifically a bracket for welding double-hook box beams. Background Technology

[0002] The double-hook box beam, through its dual-point suspension mechanical design, synchronous control system, and high-temperature resistant structure, achieves efficient and safe ladle hoisting. It is an indispensable key piece of equipment in the metallurgical industry. The original rigid design of the box beam can resist thermal deformation under high-temperature conditions and ensure long-term stable use. However, due to long-term ladle bearing and full-load use, cracks were found on both sides of the upper cover plate during routine inspection of the double-hook box beam. To repair the cracks, a bracket was designed and used to support the double-hook box beam and assist in subsequent support.

[0003] Chinese Patent Publication No. CN218785309U discloses a welding bracket for processing clean bench cabinets. The bracket includes a processing plate, a positioning pad fixedly mounted on the upper surface of the processing plate, connecting blocks fixedly mounted on both sides of the upper surface of the processing plate, and a small electric push rod fixedly mounted on one side of each connecting block. A clamping plate is fixedly connected to one end of the small electric push rod. When the small electric push rod is activated, it causes the clamping plates to move and adjust relative to each other, clamping and fixing the clean bench cabinet on the surface of the positioning pad. This ensures sufficient stability of the clean bench cabinet during welding, improving the welding effect. Furthermore, if the height of the clean bench cabinet becomes unsuitable during welding, the electric push rod can be activated to raise and lower the processing plate, changing the height of the clean bench cabinet and making the bracket suitable for workers of different heights.

[0004] When fixing the material to be welded, the aforementioned patented welding bracket can only clamp the material by having two clamping plates fit together. The clamping method is singular and the clamping position is fixed, which cannot adapt to different clamping needs by adjusting the clamping position. The clamping method cannot be adjusted to adapt to different welding requirements. Utility Model Content

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1 and Figure 2 As shown, a bracket for welding a double-hook box beam in this embodiment includes an I-beam 3. A pair of I-beams 3 are arranged laterally. The two I-beams 3 can support the upper double-hook box beam 1. After the pair of I-beams 3 can support the double-hook box beam 1, it can assist in the subsequent clamping and fixing of the double-hook box beam 1.

[0021] Among them, the upper end of the double hook box beam 1 is provided with an upper cover plate 2. There are crack positions 7 on both sides between the upper cover plate 2 and the double hook box beam 1. After the double hook box beam 1 is erected on the upper end of a pair of I-beams 3, the crack positions 7 are mainly welded and repaired.

[0022] In addition, in order to support the I-beam 3, support columns 4 are provided at both the front and rear ends of the lower end of the I-beam 3. The lower end of the support column 4 is provided with a horizontal bottom 6. The horizontal bottom 6, the support column 4 and the I-beam 3 are welded and fixed in sequence. The horizontal bottom 6, the support column 4 and the I-beam 3 can support and lift the double hook box beam 1 placed at the upper end by welding and fixing them in sequence.

[0023] Furthermore, in order to improve the support capacity of the welding position between the support column 4 and the horizontal bottom 6, column reinforcing plates 5 are respectively provided at the front and rear ends of the welding position between the support column 4 and the horizontal bottom 6, and the column reinforcing plates 5 are welded and fixed to the support column 4 and the horizontal bottom 6 respectively. The welding position between the support column 4 and the horizontal bottom 6 is further fixed by the column reinforcing plates 5, and the entire bracket is reinforced and supported by the column reinforcing plates 5.

[0024] In order to clamp the front and rear ends of the double-hook box beam 1 and complete the clamping of the I-beam 3 after support, a first bracket 8, a second bracket 9, a fourth bracket 11 and a third bracket 10 are arranged in a clockwise direction between the two I-beams 3. The second bracket 9 and the fourth bracket 11 are respectively welded to the side of the two I-beams 3. The welded second bracket 9 and the fourth bracket 11 can adapt to the subsequent support of the rear end of the double-hook box beam 1.

[0025] Among them, the front end of the second bracket 9 is provided with the first bracket 8, and the front end of the fourth bracket 11 is provided with the third bracket 10. The third bracket 10 moves toward the fourth bracket 11 and the first bracket 8 moves toward the second bracket 9 to complete the clamping and fixing of the front and rear ends of the double hook box beam 1.

[0026] In addition, for the transmission of the first bracket 8 and the third bracket 10, each of the two I-beams 3 has a rotatable first threaded rod 13 arranged laterally inside. The first threaded rod 13 inside the I-beam 3 connecting the first bracket 8 and the second bracket 9 is threadedly engaged, and the first threaded rod 13 inside the I-beam 3 connecting the third bracket 10 and the fourth bracket 11 is also threadedly engaged. The first threaded rods 13 inside the two I-beams 3 rotate after being driven. The rotation of the first threaded rods 13 can laterally adjust the position of the first bracket 8 and the third bracket 10, which can achieve clamping on both the front and rear sides of the double hook box beam 1.

[0027] In order to clamp the upper and lower sides of the double-hook box beam 1 and complete the clamping after the I-beam 3 is supported, the first bracket 8, the second bracket 9, the fourth bracket 11 and the third bracket 10 are all provided with pressing plates 12 on the outside. The pressing plates 12 are embedded in the first bracket 8, the second bracket 9, the fourth bracket 11 and the third bracket 10 and are slidably connected to the inside of the first bracket 8, the second bracket 9, the fourth bracket 11 and the third bracket 10. After the position is adjusted by pressing plates 12, the double-hook box beam 1 can be pressed and clamped.

[0028] In order to improve the longitudinal stability of the double-hook box beam 1, the pressing plates 12 corresponding to the first bracket 8 and the third bracket 10 are set towards the second bracket 9 and the fourth bracket 11, and the pressing plates 12 corresponding to the second bracket 9 and the fourth bracket 11 are set towards the first bracket 8 and the third bracket 10. The pressing plates 12 in the two directions can cooperate with each other and cope with the double-hook box beam 1 of different sizes.

[0029] In addition, the first bracket 8 corresponds to the pressing plate 12 located above the second bracket 9 corresponding to the pressing plate 12, and the fourth bracket 11 corresponds to the pressing plate 12 located above the third bracket 10 corresponding to the pressing plate 12. The upper and lower ends of both sides of the double hook box beam 1 are clamped by contacting the pressing plate 12 respectively. The front end of one side of the double hook box beam 1 and the rear end of the other side are contacted by the upper pressing plate 12, while the rear end of one side of the double hook box beam 1 and the front end of the other side are contacted by the lower pressing plate 12. The double hook box beam 1 is clamped by contacting the pressing plate 12 at the diagonal position, which can improve the stability of the double hook box beam 1 when clamped in the horizontal position.

[0030] In order to drive the pressing piece 12 inside the first bracket 8, the second bracket 9, the fourth bracket 11 and the third bracket 10, a second threaded rod 14 is vertically arranged inside the first bracket 8, the second bracket 9, the fourth bracket 11 and the third bracket 10. The second threaded rod 14 passes through the pressing piece 12 and is threadedly engaged with the through position of the pressing piece 12. After being driven, the second threaded rod 14 rotates and, combined with the constraint of the first bracket 8, can horizontally adjust the pressing piece 12.

[0031] To accommodate the contact between the first bracket 8, the second bracket 9, the fourth bracket 11, and the third bracket 10 and the double-hook box beam 1 and improve the fit, a gasket 15 is provided on the side of the first bracket 8 and the third bracket 10 facing the second bracket 9 and the fourth bracket 11, and a gasket 15 is provided on the side of the second bracket 9 and the fourth bracket 11 facing the first bracket 8 and the third bracket 10. The gasket 15 is glued to the first bracket 8, the second bracket 9, the fourth bracket 11, and the third bracket 10 respectively. The gasket 15 glued together can improve the clamping effect after it is attached to the double-hook box beam 1.

[0032] Working principle: When using a welding bracket for the double-hook box beam to support the double-hook box beam and to weld and repair the crack position 7 on the surface of the double-hook box beam, the two sides of the lower end of the double-hook box beam 1 are respectively placed on the upper ends of two I-beams 3. The two I-beams 3 are supported by support columns 4 at the front and rear ends of the lower end, column reinforcing plates 5, and horizontal bottom 6. When it is necessary to clamp the front and rear sides of the double-hook box beam 1, the motor corresponding to the first threaded rod 13 is started. The rotation of the first threaded rod 13, after being restricted by the I-beams 3, causes the first bracket 8 and the third bracket 10 to slide laterally along the I-beams 3. The first bracket 8 and the third bracket 10 move toward the second bracket 9 and the fourth bracket 11 respectively. During the movement, the double-hook box beam 1 is pushed into contact with the second bracket 9 and the fourth bracket 11. As the first bracket 8 and the third bracket 10 continue to move, the first bracket 8 and the second bracket 9... The front and rear sides of one side of the double-hook box beam 1 are clamped, so that the front and rear sides of the other side of the double-hook box beam 1 are clamped by the third bracket 10 and the fourth bracket 11. It is necessary to clamp the upper and lower ends of the double-hook box beam 1. There is no need to drive the first threaded rod 13 and adjust the position of the first bracket 8. The motors corresponding to the upper ends of the first bracket 8, the second bracket 9, the third bracket 10 and the fourth bracket 11 are started to drive the second threaded rod 14 to rotate. The rotation of the second threaded rod 14 is restricted by the first bracket 8, the second bracket 9, the third bracket 10 and the fourth bracket 11 themselves, so that the pressing plate 12 is adjusted to a horizontal position. The upper and lower ends of one side of the double-hook box beam 1 are clamped by the pressing plate 12 outside the first bracket 8 and the second bracket 9 respectively. The upper and lower ends of the other side of the double-hook box beam 1 are clamped by the pressing plate 12 outside the fourth bracket 11 and the third bracket 10 respectively. Two clamping orientations are provided to adapt to different welding requirements.
