Technical Field
[0001] This application relates to the field of bridge building machine technology, and in particular to a C-type load-bearing structure for a bridge building machine. Background Technology
[0002] In bridge-building machine structures, a C-shaped load-bearing structure is typically installed at the rear end to anchor the structure to the already poured section. Traditional C-shaped load-bearing structures refer to... Figure 1 As shown, it typically includes a main hanger in the middle and C-hooks at both ends, with the C-hooks needing to wrap around to the underside of the bridge wing. Because the bridge end face usually requires the installation of complex trusses, hanging baskets, and other structures, the C-shaped load-bearing structure cannot be horizontally hoisted into place as a whole from the end face of the already poured section. Generally, installing a C-shaped load-bearing structure involves first hoisting the main hanger from the top, then hoisting the C-hooks at both ends, aligning the C-hooks with the main hanger, and then bolting them together. This requires at least three hoisting operations, and also necessitates aligning the C-hooks with the main hanger in mid-air, resulting in a large overall construction workload and high construction difficulty.

[0035] Example
[0036] Reference Figure 2As shown, this embodiment provides a C-shaped load-bearing structure for a bridge-building machine, including a main hanger 1, a C-shaped hook 2, and an adjusting cylinder 3. The main hanger 1 is installed on top of the poured section, and the C-shaped hook 2 extends to the underside of the wing plate. The C-shaped hook 2 includes a diagonal rod 21 and a hook portion 22. The diagonal rod 21 includes a first end and a second end, with the first end connecting to the hook portion 22 to form a C-shaped hook. A hinge portion 23 is provided in the middle of the diagonal rod 21, and the hinge portion 23 is hinged to the end of the main hanger 1. A first connecting portion 24 and a second connecting portion 25 are respectively provided on both sides of the hinge portion 23, and the first connecting portion 24 or the second connecting portion 25 is connected to the main hanger 1.
[0037] One end of the adjusting cylinder 3 is hinged to the main hanger 1, and the other end is hinged to the second end of the diagonal rod 21; it is used to drive the C-shaped hook 2 to rotate.
[0038] By adjusting the hydraulic cylinder 3 to drive the C-hook 2 to rotate around the axis of the hinge 23, the C-hook 2 can be switched between the extended and retracted states. (Refer to...) Figure 2 As shown, when the C-hook 2 is in the unfolded state, the distance between the ends of the two C-hook 2 is greater than the width of the bridge wing plate. During the installation of the C-type load-bearing structure, it is hoisted in the unfolded state above the poured section. Then, the C-type load-bearing structure is lowered onto the support structure on top of the poured section by the main hanger 1. After fixing the main hanger 1, the C-hook 2 is rotated by adjusting the hydraulic cylinder 3, allowing the C-hook 2 to rotate around to the underside of the wing plate, thus positioning the entire C-type load-bearing structure.
[0039] It should be noted that when the C-hook 2 is in the extended state, the second connecting part 25 is connected to the main hanger 1, thereby relieving the force on the adjusting cylinder 3 and ensuring the overall stability of the C-shaped load-bearing structure during the hoisting process; when the C-hook 2 is in the retracted state, the first connecting part 24 is connected to the main hanger 1, thereby relieving the force on the adjusting cylinder 3 and ensuring the overall stability of the C-shaped load-bearing structure during the construction process.
[0040] This embodiment provides a C-shaped load-bearing structure for a bridge-building machine. By adjusting the C-shaped hook 2 to the extended state, the entire C-shaped load-bearing structure can be hoisted and lowered into place from above the already poured section. After placement, retracting the C-shaped hook 2 allows the entire C-shaped load-bearing structure to be installed in position. This invention enables the entire C-shaped load-bearing structure to be hoisted in one go without the need for high-altitude alignment, thus reducing the overall construction workload and difficulty.
[0041] Specifically, continue to refer to Figure 4As shown, the main hanger 1 includes two sub-rods 11 and multiple connecting plates 12. A gap is formed between the two sub-rods 11, and the multiple connecting plates 12 are respectively connected to the two sub-rods 11, making the two sub-rods 11 form a whole. During the pouring construction process, the main hanger 1 needs to be anchored to the poured section through the hanger structure. The gap between the two sub-rods 11 allows the hanger rods to pass through, facilitating the installation of the hanger rods on the main hanger 1.
[0042] Specifically, the inclined rod 21 includes a first rod body 211 and a second rod body 212. One end of the first rod body 211 is connected to the hook 22, and the other end is connected to the second rod body 212. The second rod body 212 extends outward through the gap and is hinged to the adjusting cylinder 3. The thickness of the second rod body 212 is less than the thickness of the gap, thus facilitating the hinged connection of the second rod body 212 to the adjusting cylinder 3 after passing through the gap. This ensures that the end of the adjusting cylinder 3 is located within the gap, facilitating the angle adjustment of the adjusting cylinder 3.
[0043] Specifically, the end of the sub-rod 11 is provided with a ring 13, and the two sides of the second rod 212 are respectively provided with coaxially arranged hinge columns, which are rotatably installed in the ring 13. The hinge between the diagonal rod 21 and the main hanger 1 is realized through the cooperation of the ring 13 and the hinge columns.
[0044] Specifically, the first connecting part 24 is disposed on the first rod body 211, and the bottom surface of the end of the main hanger 1 is provided with a first bolting part 14; when the C-shaped hook 2 is rotated to the retracted state, the first connecting part 24 abuts against and bolts to the first bolting part 14.
[0045] The second connecting part 25 is disposed on the second rod body 212, and the top surface of the main hanger 1 is provided with a second bolting part 15; when the C-shaped hook 2 is rotated to the unfolded state, the second connecting part 25 abuts against and bolts to the second bolting part 15.
[0046] In the folded state, the first connecting part 24 is bolted to the first bolted part 14, and in the unfolded state, the second connecting part 25 is bolted to the second bolted part 15. This improves the overall stability of the C-shaped load-bearing structure during hoisting and subsequent construction. Furthermore, the assembly and disassembly methods are simple and do not require additional alignment operations, thus improving the construction efficiency of workers.
[0047] Specifically, refer to Figure 3 As shown, the first bolted portion 14 includes a first bolted plate 141 and a first reinforcing plate 142; the first bolted plate 141 is connected to two sub-rods 11 respectively and extends downward in the vertical direction; one end of the first reinforcing plate 142 is connected to the sub-rod 11, and the other end is connected to the first bolted plate 141; the first connecting portion 24 is bolted to the first bolted plate 141 after being fitted together. (Refer to...) Figure 2As shown, the second bolted part 15 includes a second bolted plate 151 and a second reinforcing plate 152; the second bolted plate 151 is connected to two sub-rods 11 respectively and extends obliquely; one end of the second reinforcing plate 152 is connected to the sub-rod 11 and the other end is connected to the first bolted plate 141; the second connecting part 25 is bolted to the second bolted plate 151 after being fitted together.
[0048] The first bolt plate 141 and the second bolt plate 151 can respectively limit the rotation of the C-hook 2 to avoid excessive rotation, while providing an installation node for the C-hook 2.
[0049] Specifically, refer to Figure 3 As shown, when the C-hook 2 rotates to the unfolded state, the inclined rod 21 is arranged at an angle. The inclined rod 21 can pass through the gap and hinge with the adjusting cylinder 3. In this embodiment, the adjusting cylinder 3 can be set at the gap position, thereby maximizing the retraction of the adjusting cylinder 3.
[0050] Installation process:
[0051] Using the adjusting cylinder 3, drive the C-hook 2 to rotate to the unfolded state, so that the distance between the ends of the two C-hook 2 is greater than the width of the wing plate, and bolt the second connecting part 25 to the second bolted part 15. Hoist the entire C-shaped load-bearing structure to the top of the poured section, and then lower the C-shaped load-bearing structure until it abuts against the support structure on the poured section with the main hanger 1. After connecting the main hanger 1 to the support structure, disassemble the second connecting part 25 and the second bolted part 15; use the adjusting cylinder 3 to drive the C-hook 2 to rotate to the position, and bolt the first connecting part 24 to the first bolted part 14.
[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
