Technical Field

[0001] The present application relates to the technical field of bridge-building machines, and in particular to a suspension rod mechanism of a continuous beam bridge-building machine. Background Art

[0002] The application of bridge-building machines not only greatly shortens the construction period of bridges, but also improves the safety and quality of bridge construction. In the process of using a bridge-building machine to build a bridge, the positions of the lifting points of some of its suspension rods need to be adjusted when pouring concrete and when the bridge-building machine is moving. When pouring concrete, one of the lifting points of the rear suspension rod at the rear crossbeam position needs to be set on the rear crossbeam, and when the bridge-building machine moves, the lifting point needs to be transferred to the wing plate of the poured beam. In the existing scheme, the structure at the lifting point position needs to be completely disassembled when converting the lifting point, which makes the operation cumbersome and affects the construction efficiency. In addition, in the prior art, the other lifting point of the rear suspension rod is fixed on the wing plate formwork, and the lifting point needs to be removed when demolding, further affecting the construction efficiency.

[0035] Example

[0036] This embodiment provides a suspension rod mechanism of a continuous beam bridge-building machine, which includes a rear cross beam 1, a C-shaped frame 2, a first rear suspension rod 3 and a second rear suspension rod 4. The C-shaped frames 2 are respectively connected to both ends of the rear cross beam 1, the rear cross beam 1 is located above the cast beam 9, and the C-shaped frame 2 is wound around to the bottom of the wing plate of the cast beam 9.

[0037] Reference Figure 1 and Figure 2As shown, when pouring concrete, one end of the first rear suspension rod 3 is fixed to the rear cross beam 1 by the first suspension point 5, and the other end is fixed to the C-shaped frame 2 by the second suspension point 6. Figure 4 As shown, the rear suspension rod includes three rod bodies 31 connected in sequence to form two quick-release nodes 32, one of which is located between the wing plate of the cast beam 9 and the C-frame 2, and the other is located between the wing plate of the cast beam 9 and the rear cross beam 1.

[0038] Reference Figure 3 As shown, when the bridge-building machine is moving, one end of the second rear suspension rod 4 is fixed to the wing plate of the cast beam 9 by the third suspension point 7, and the other end is fixed to the C-frame 2 by the fourth suspension point 8; the second rear suspension rod 4 includes two rod bodies 31 connected in sequence and form a quick-release node 32 located between the wing plate of the cast beam 9 and the C-frame 2.

[0039] For example, when the concrete is poured and cured and the bridge machine needs to be switched to the walking mode, the first suspension point 5 needs to be switched from the rear cross beam 1 to the wing of the poured beam 9, that is, the first suspension point 5 is switched to the third suspension point 7. By removing the two quick-release nodes 32 and then reducing the middle rod 31, the rod 31 connected to the first suspension point 5 is moved as a whole to pass through the wing of the poured beam 9, and the remaining two rods 31 are connected through the quick-release nodes 32, and the second rear suspension rod 4 is formed at this time, that is, the difference between the first rear suspension rod 3 and the second rear suspension rod 4 lies in the number of rods 31 and the position of the first suspension point 5.

[0040] The embodiment provides a suspension rod mechanism for a continuous beam bridge-building machine. When converting the suspension points on the rear cross beam 1 and the wing plate of the cast beam 9, it is only necessary to dismantle the quick-release node 32 and then add or reduce a rod body 31. It is not necessary to dismantle the suspension point structure as a whole, thereby reducing the construction workload and improving the construction efficiency. In addition, the other suspension point of the rear suspension rod is fixed on the C-frame 2, so that the suspension point does not need to be dismantled when the wing plate template is demoulded, further improving the construction efficiency.

[0041] Specifically, refer to Figure 4 As shown, the first suspension point 5 includes a jack 51, a first pad 52 and a first nut 53. The first rear suspension rod 3 passes through the rear cross beam 1, the jack 51 and the first pad 52 in sequence and is locked with the first nut 53, so that the first suspension point 5 is fixed to the rear cross beam 1 or the wing plate of the cast beam 9. During the suspension point conversion process, the jack 51 and the corresponding rod body 31 do not need to be disassembled and can be directly transferred as a whole.

[0042] Specifically, the second suspension point 6 includes a second pad 61 and a second nut 62 , and the first rear suspension rod 3 passes through the C-shaped frame 2 and the second pad 61 in sequence and is locked with the second nut 62 .

[0043] Specifically, refer to Figure 5 and Figure 6 As shown, the quick-release node 32 includes a first quick-release head 33, a second quick-release head 34 and a locking handle 35. The first quick-release head 33 includes two spaced connection plates 331, which are respectively connected to one end of the rod body 31, and a first elliptical through hole 332 is provided on the connection plate 331; the second quick-release head 34 is the end of another rod body 31, and a second elliptical through hole 341 is provided on the second quick-release head 34. The locking handle 35 includes a handle 351, a locking rod 352 and a locking head 353, and the locking head 353 is elliptical, and the locking head 353 passes through the first elliptical through hole 332 and the second elliptical through hole 341 in sequence, and then rotates 90° to connect the first quick-release head 33 and the second quick-release head 34.

[0044] Specifically, a locking groove is provided on the outer side of a connecting plate 331, and a locking block 354 is provided at one end of the lock head 353 facing the handle 351 to cooperate with the locking groove. When the lock head 353 rotates 90°, the locking block 354 cooperates with the locking groove, thereby preventing the locking handle 35 from rotating by itself, and ensuring the reliability of the connection between the rod bodies 31. The locking block 354 includes a first arcuate surface, and the locking groove includes a second arcuate surface, and the first arcuate surface is in contact with the second arcuate surface. During the rotation of the lock head 353, it is guided by the first arcuate surface and the second arcuate surface to the locking groove and cooperate with the locking block 354.

[0045] Specifically, a compression spring 36 is sleeved on the locking rod 352, one end of the compression spring 36 abuts against the handle 351, and the other end abuts against the connecting plate 331; the compression spring 36 has an elastic force to move the locking handle 35 toward the direction of the handle 351. When the lock head 353 rotates 90° until the locking groove and the locking block 354 are matched, the first arc surface and the second arc surface are closely fitted under the action of the compression spring 36, so that the locking handle 35 is prevented from rotating by itself, and the reliability of the connection of the rod body 31 is further improved.

[0046] Specifically, the inner diameter of the compression spring 36 is smaller than the length of the major axis of the lock head 353 and larger than the length of the minor axis of the first elliptical through hole 332. On the one hand, the compression spring 36 is prevented from entering the first elliptical through hole 332, and on the other hand, the spring is prevented from falling off from one end of the lock head 353 after the locking handle 35 is disassembled.

[0047] Working principle:

[0048] Taking the process of switching from the first lifting point 5 to the third lifting point 7 as an example, first, the jack 51 unloads the force, and then the two quick-release nodes 32 are removed. When removing the quick-release node 32, press the locking handle 35 in the direction of the lock head 353 so that the locking block 354 is disengaged from the locking groove, and then rotate the lock head 353 90° until the lock head 353 is aligned with the first elliptical through hole 332 and the second elliptical through hole 341, and finally pull out the locking handle 35. After removing the quick-release node 32, take away the rod body 31 in the middle part, and then transfer the jack 51 and the corresponding rod body 31 to the wing plate of the cast beam 9, and then connect the quick-release node 32, so that the jack 51 lifts the suspension rod to the designed position.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
