Description

Technical Field

[0001] This application relates to the field of bridge building machine technology, and in particular to a C-beam integral hoisting device for a bridge building machine. Background Technology

[0002] Bridge-building machines play a crucial role in bridge construction, significantly improving construction efficiency, reducing labor costs, and ensuring construction quality. Through their precise positioning and stable support, bridge-building machines make bridge construction faster, safer, and more efficient.

[0003] Referring to invention patent CN114737489B, which discloses a construction method for a self-propelled cantilever bridge-building machine, the structure of the machine is also disclosed. The bridge-building machine typically requires the installation of three C-beams (i.e., hook beams), with two C-beams located at either end of the main beam and one C-beam in the middle. Because the ends of the C-beams are hook-shaped, if a single-piece hoisting method is used, interference can easily occur between the C-beams and the main beam and the already poured bridge deck during the transfer to the designed position. Therefore, in traditional operations, C-beams are usually installed by segmented hoisting followed by high-altitude assembly. Ensuring the installation accuracy between the segments of the C-beam during high-altitude assembly presents significant operational challenges. Therefore, a hoisting device capable of single-piece hoisting of C-beams is needed. Utility Model Content

[0039] Example

[0040] Reference Figure 1 As shown, this embodiment provides a C-beam hoisting device for a bridge-building machine, including two longitudinal beams 1, multiple diamond-shaped frames 2, a first translation trolley 3, a lifting mechanism 4, and a second translation trolley 5. Specifically, the bridge-building machine includes two main beams 6 and three C-beams. The two main beams 6 are installed on the bridge deck, with one end of each main beam extending outward toward the end face of the bridge body 101. The three main beams 6 are distributed at both ends and the middle of the main beams 6. During the C-beam hoisting, the main beams 6 are already installed on the bridge deck, and are used as an auxiliary to hoist the C-beams as a whole. The C-beams are pre-assembled on the overall platform, and the assembly accuracy of the C-frames is ensured by ensuring the flatness of the platform.

[0041] Specifically, refer to Figure 2 As shown, the two ends of the two longitudinal beams 1 are respectively connected to the two main beams 6. Specifically, the connection can be made by bolting. After the C-shaped beam is hoisted, the two longitudinal beams 1 can be removed, thereby dismantling the entire hoisting equipment.

[0042] Specifically, continue to refer to Figure 2 As shown, the bottom of the rhombus-shaped frame 2 is connected to two longitudinal beams 1, and one end of the top of the rhombus-shaped frame 2 extends outward toward the end of the main beam 6. The first translation trolley 3 is mounted on the top of the rhombus-shaped frame 2, moving along the length of the main beam 6. The lifting mechanism 4 is mounted on the first translation trolley 3. Because one end of the top of the rhombus-shaped frame 2 extends outward toward the end of the main beam 6, by moving the first translation trolley 3 to the outside of the end of the main beam 6, the lifting mechanism 4 is positioned outside the end of the main beam 6, thus enabling the vertical lifting of the C-shaped frame and avoiding interference between the C-shaped frame and the main beam 6 during vertical lifting. Multiple rhombus-shaped frames 2 are arranged along the length of the longitudinal beams 1 to ensure the stability of the C-shaped frame during vertical lifting.

[0043] Specifically, the second translation trolley 5 is installed on top of the main beam 6, moving along its length. When hoisting each C-beam, after the C-beam is vertically lifted above the main beam 6, the C-beam can be placed on the second translation trolley 5 or the main beam 6 by moving the first translation trolley 3. After hoisting three C-beams, the overall hoisting equipment can be dismantled, and the C-beams can be transferred to the designed position by moving the second translation trolley 5.

[0044] The C-beam hoisting equipment for a bridge-building machine disclosed in this embodiment can hoist the C-beam as a whole through the hoisting mechanism 4 on the diamond frame 2. Through the transfer of the first translation trolley 3 and the second translation trolley 5, each C-beam can be arranged to the design position. This realizes the hoisting and transfer of each C-beam to the corresponding position as a whole, thereby reducing the difficulty of assembling the C-beam at high altitude.

[0045] Specifically, refer to Figure 4 As shown, the rhombus frame 2 includes a first horizontal bar 21, a second horizontal bar 22, a first diagonal bar 23, a second diagonal bar 24, and a vertical bar 27; the first horizontal bar 21, the first diagonal bar 23, the second horizontal bar 22, and the second diagonal bar 24 are connected end to end to form a rhombus shape; one end of the vertical bar 27 is connected to the first horizontal bar 21, and the other end is connected to the second horizontal bar 22.

[0046] Specifically, the connection node between the first diagonal brace 23 and the second horizontal brace 22 extends outward toward the end of the main beam 6; the second horizontal brace 22 includes two sub-braces 25, with a gap between the two sub-braces 25 to accommodate the hoisting rope 41 of the lifting mechanism 4. Correspondingly, a gap to accommodate the hoisting rope 41 is also provided on the first diagonal brace 23. This facilitates the passage of the hoisting rope 41 during the lifting of the C-shaped frame. It should be noted that the hoisting point between the hoisting rope 41 and the C-shaped frame can be formed by using a hook or a bolt connection, or other forms of hoisting points in the prior art can be selected.

[0047] Specifically, refer to Figure 5 As shown, the first translation trolley 3 movably presses against the second horizontal bar 22; limiting plates 31 are respectively provided on both sides of the first translation trolley 3, and the limiting plates 31 abut against the side of the second horizontal bar 22. The limiting plates 31 restrict the relative movement between the first translation trolley 3 and the second horizontal bar 22, thereby allowing the first translation trolley 3 to move along the length of the main beam 6 on the second horizontal bar 22.

[0048] Specifically, a horizontal drive cylinder 26 is installed on the second horizontal bar 22; the horizontal drive cylinder 26 is connected to the first translation trolley 3 and is used to drive the first translation trolley 3 to move along the length direction of the main beam 6. The first translation trolley 3 is moved by the horizontal drive cylinder 26, thereby controlling the position of the first translation trolley 3.

[0049] Specifically, refer to Figure 6 As shown, the main beam 6 has a wing plate 61 on its side; the second translation trolley 5 includes a support part 51, a drive wheel 52, a drive motor, and a reverse hook part 53; the support part 51 is used to support the C-shaped beam; the drive motor is mounted on the support part 51, the drive wheel 52 is rotatably connected to the bottom of the support part 51 and presses against the top of the main beam 6; the drive motor is connected to the drive wheel 52 and is used to drive the drive wheel 52 to rotate; the two sides of the support part 51 are respectively connected to the reverse hook part 53, and the side of the reverse hook part 53 away from the support part 51 extends into the underside of the wing plate 61. The reverse hook part 53 restricts the relative movement between the second translation trolley 5 and the main beam 6, so that the second translation trolley 5 can only move along the length direction of the main beam 6. The position of the second translation trolley 5 is changed by driving the second translation trolley 5 to move on the main beam 6.

[0050] Specifically, it also includes a conversion cylinder 10; the conversion cylinder 10 is installed on the bridge deck and located between the two main beams 6. When the second translation trolley 5 transfers the C-shaped beam to the designed position, the conversion cylinder 10 lifts the C-shaped beam, and then the second translation trolley 5 is removed, causing the conversion cylinder 10 to retract, thereby placing the C-shaped beam on the main beam 6.

[0051] Construction process:

[0052] Reference Figure 3 As shown, in this embodiment, the three C-shaped frames that need to be lifted are a first C-shaped frame 7, a second C-shaped frame 8, and a third C-shaped frame 9. After installing the main beam 6, a second translation trolley 5 is installed on the main beam 6, moving the second translation trolley 5 to the end position of the main beam 6 and reserving installation space for the first C-shaped frame 7. Then, a longitudinal beam 1 is installed on the main beam 6, positioning the second translation trolley 5 between the end of the main beam 6 and the longitudinal beam 1. A diamond-shaped frame 2 is then installed on the longitudinal beam 1, and the first translation trolley 3 and the lifting mechanism 4 are installed accordingly. The three C-shaped frames are vertically lifted by the cooperation of the lifting mechanism 4 and the first translation trolley 3, so that the first C-shaped frame 7 is placed directly at the designed position of the main beam 6, that is, the end of the main beam 6 extending out of the bridge body 101, and the second C-shaped frame 8 and the third C-shaped frame 9 are placed on the second translation trolley 5 respectively. Then, the longitudinal beam 1 and the diamond frame 2 are dismantled. The second C-frame 8 and the third C-frame 9 are moved by the second translation trolley 5. When they move to the corresponding design position, the corresponding C-frame is transferred to the main beam 6 by the conversion cylinder 10, thereby completing the overall hoisting of each C-frame.

[0053] 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.

[0054] 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.
