[0003] In the patent with publication number CN217735526U, an automatic steel bar laying trolley is disclosed, which relates to the technical field of steel bar laying. The automatic steel bar laying trolley comprises: a support plate, at both ends of the bottom of the support plate, at least two support columns evenly distributed along its width direction are fixedly installed, the bottom ends of multiple support columns on the same side are fixedly installed with a bottom plate, the bottom end of the bottom plate is installed with track wheels for driving the device to walk along the track, two groups of support columns on both sides of the bottom of the support plate are fixedly installed with side station plates on the side away from each other, at least two arc-shaped support frames evenly distributed along its length direction are installed on the top of the support plate, and fixed blocks are fixedly installed between the two ends of the arc-shaped support frame and the two side station plates respectively, and at least two tightening components for tightening the steel bars against the arc-shaped wall of the tunnel are installed on the side of the arc-shaped support frame away from the support plate. The laying quality of the device is improved, and the device can lay multiple steel bars at the same time, which improves the laying efficiency of the device. However, this device cannot ensure that the spacing between each steel bar is consistent during laying, which will seriously affect the load-bearing performance of the bridge and make the bridge construction unqualified.

[0023] Example 1

[0024] A bridge beam reinforcement quick assembler, such as Figure 1-Figure 3 As shown, it includes a support frame 1, moving wheels 11, a telescopic cylinder 12, a handle 13, a placement box 14 and a laying mechanism. The left and right sides of the bottom of the support frame 1 are rotatably connected with the moving wheels 11 which are symmetrically distributed front and back. The front and back sides of the top of the support frame 1 are fixedly connected with handles 13. The left side of the support frame 1 is fixedly connected with the placement box 14. The support frame 1 and the placement box 14 can be equally divided into two parts, wherein the front support frame 1 is fixedly connected with the telescopic cylinder 12, and the output end of the telescopic cylinder 12 is fixedly connected with the rear support frame 1, and the placement box 14 is provided with a laying mechanism.

[0025] like Figure 1-Figure 3 As shown, the laying mechanism includes a placement wheel 2, a rotating shaft 21, a connecting frame 22, a rotating frame 23 and a support plate 24. The placement box 14 is fixedly connected to the front and rear sides of the bottom with a connecting frame 22. The right side of the connecting frame 22 is rotatably connected to the rotating shaft 21. The outside of the rotating shaft 21 is fixedly connected to the placement wheel 2. The outer side of the placement wheel 2 is fixedly connected to the rotating frame 23 distributed circumferentially. The placement box 14 is fixedly connected to the front and rear sides of the bottom with a support plate 24.

[0026] like Figure 4As shown, it also includes an arc frame 3, a telescopic rod 31 and a spring 32. The outside of the rotating shaft 21 is fixedly connected to the telescopic rod 31 distributed circumferentially, and the end of the telescopic rod 31 away from the rotating shaft 21 is fixedly connected to the arc frame 3. The spring 32 is fixedly connected between the arc frame 3 and the telescopic rod 31, and the arc frame 3 is slidably connected to the placement wheel 2.

[0027] like Figure 5 and Figure 6 As shown, it also includes a knocking block 4, an annular wheel group 41, a compression spring 42, a bracket 43 and a limit frame 44, wherein the annular wheel group 41 includes a static wheel and a dynamic wheel, and the static wheel fits perfectly with the dynamic wheel, the front and rear sides of the placement box 14 are fixedly connected to the limit frame 44, the limit frame 44 is slidably connected with the bracket 43 inside, the knocking block 4 is fixedly connected to the side of the bracket 43 close to the placement wheel 2, the dynamic wheel in the annular wheel group 41 is fixedly connected to the side of the bracket 43 close to the rotating shaft 21, the compression spring 42 is fixedly connected between the dynamic wheel and the limit frame 44, and the static wheel in the annular wheel group 41 is fixedly connected to the side of the rotating shaft 21 close to the limit frame 44.

[0028] like Figure 4 As shown, the outer side of the placing wheel 2 is provided with circumferentially distributed arc-shaped notches for equidistantly laying steel bars.

[0029] like Figure 3 As shown, the rotating frame 23 is made of rubber material to fit the ground and prevent the placement wheel 2 from being worn.

[0030] When workers build a bridge and need to lay steel bars, they can first start the telescopic cylinder 12 and adjust the two-part support frame 1 and the placement box 14 to a suitable distance according to the length of the steel bars to be laid. Then, multiple steel bars are placed in the placement box 14, and the steel bars at the lowest part of the placement box 14 will fall into the arc-shaped notch of the placement wheel 2. The falling of the steel bars will squeeze the arc frame 3 and move the arc frame 3 toward the direction close to the rotating shaft 21. The telescopic rod 31 and the spring 32 will be compressed immediately. Then the worker grabs the handle 13 and drags the device to the right, and the moving wheel 11 and the placement wheel 2 will start to rotate immediately. When the placement wheel 2 rotates 90 degrees, another steel bar will fall into another arc-shaped notch. If the placement wheel 2 rotates, the arc frame 3 that has supported the steel bars will move a distance away from the rotating shaft 21 under the action of the spring 32 resetting, and cooperate with the support plate 24 to clamp and fix the steel bars to avoid the left and right deviation of the steel bars, which causes the laid steel bars to be non-parallel to each other. At the same time, it can also prevent the steel bars from rotating before they are fully rotated. When the placing wheel 2 drives the steel bar to rotate and separate from the supporting plate 24, the steel bar falls and is laid on the ground. The corresponding arc frame 3 will also move and reset in the direction away from the rotating shaft 21 under the action of the spring 32. The placing wheel 2 continues to rotate and the steel bar will continue to be laid. During this period, if the placing wheel 2 rotates, the static wheel in the annular wheel group 41 will rotate and squeeze the dynamic wheel through the convexity of the grain, so that the dynamic wheel, the bracket 43 and the knocking block 4 move in the direction away from the rotating shaft 21, and the compression spring 42 is compressed immediately. When the static wheel rotates until the dynamic wheel enters the recess of the static wheel, the dynamic wheel, the bracket 43 and the knocking block 4 move and reset in the direction close to the rotating shaft 21 under the action of the compression spring 42. At this time, the knocking block 4 knocks the steel bar on the top of the placing wheel 2, so that the steel bar moves back and forth to a suitable position to ensure that the laid steel bar is aligned front and back, so that the steel bar can be quickly laid on the ground or steel frame with equal spacing and alignment.
