[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Embodiment. A steel pipe support frame for a bridge widening and erecting machine, the structure of which is referenced to Figure 1-3As shown, it includes a cap beam 1, an integral cushion stone 2 is anchored at the top of the cap beam 1, an embedded steel plate 3 is fixedly connected inside the integral cushion stone 2, a steel pipe 4 is welded to the top of the embedded steel plate 3, a plurality of stiffening steel plates 5 are fixedly connected to the side of the steel pipe 4, a sleeper 6 is movably connected to the top of the steel pipe 4, the sleeper 6 and the stiffening steel plate 5 are fixed by U-shaped bolts 7, a bridge-building machine is movably connected to the top of the sleeper 6, and an existing bridge is arranged on the side of the cap beam 1.

[0018] First, place several cushion stones and embedded steel plates 3 on the top of the cap beam 1. After the placement is completed, pour concrete on the top of the cap beam 1 so that an integral cushion stone 2 can be formed on the top of the cap beam 1. Then, place the steel pipe 4 and weld it to the top of the embedded steel plate 3. The stiffening steel plate 5 is helpful to improve the stability of the steel pipe 4. Next, lay the sleeper 6 on the top of the steel pipe 4. The sleeper 6 can be fixed to the top of the steel pipe 4 with the U-shaped bolts 7, so as to avoid the displacement of the sleeper 6 during use. The installation of the steel pipe support frame for the bridge widening bridge erection machine can be completed through the above steps. The front leg support of the bridge erection machine is supported on the existing bridge and the top of the sleeper 6 for erection. Finally, all components can be inspected and accepted, thereby solving the problem that the length of the widened bridge cap beam 1 cannot meet the width requirement of the bridge erection machine. It has strong applicability in actual engineering, and the whole installation process is simple and convenient, with sufficient rigidity and structural stability. The reuse rate of the steel pipe support frame is high in similar projects, and the cost of use can be saved compared with the floor-standing steel pipe support frame.

[0019] See also Figure 1 , Figure 2 and Figure 3 The bottom end of the embedded steel plate 3 is fixedly connected with the embedded steel bar 8, and the embedded steel bar 8 is in a J shape. The bottom end of the embedded steel plate 3 is fixedly connected with the embedded steel bar 8, and the embedded steel bar 8 is in a J shape, which can increase the contact area between the embedded steel plate 3 and the integral pad stone 2, thereby further improving the stability of the embedded steel plate 3.

[0020] A number of steel bar pull rings 9 are fixedly connected to the side of the steel pipe 4, and the steel bar pull rings 9 are movably connected to the embedded steel bars 8, and the number of the steel bar pull rings 9 is consistent with the number of the embedded steel bars 8. Before casting to form the integral cushion stone 2, the steel pipe 4 is placed on the surface of the embedded steel plate 3, and then the steel bar pull ring 9 connected to one end of the steel pipe 4 is put on the surface of the embedded steel bar 8, and then the integral cushion stone 2 is cast to the top of the cap beam 1. Through the above steps, not only can the steel pipe 4 be pre-positioned at the top of the embedded steel plate 3, which is convenient for welding the steel pipe 4 to the top of the embedded steel plate 3, but also the firmness of the connection between the steel pipe 4 and the embedded steel plate 3 can be further improved, thereby improving the stability of the steel pipe 4.

[0021] The reinforcing steel plates 5 and the steel bar pull rings 9 are distributed at intervals in a circular pattern on the side of the steel pipe 4, and the reinforcing steel plates 5 are triangular in shape. The reinforcing steel plates 5 and the steel bar pull rings 9 are distributed at intervals in a circular pattern on the side of the steel pipe 4 to prevent the reinforcing steel plates 5 from blocking the moving path of the steel bar pull ring 9 when the steel bar pull ring 9 connected to one end of the steel pipe 4 is put on the surface of the embedded steel bar 8. The reinforcing steel plates 5 are triangular in shape to provide additional support for the steel pipe 4 and the sleepers 6, thereby further improving the stability of the steel pipe 4 and the sleepers 6.

[0022] A plurality of channel steels 10 are welded to the side of the steel pipe 4, and the channel steels 10 are perpendicular to the steel pipe 4. The channel steels 10 can improve the firmness of the steel pipe 4 when in use.

[0023] The sleepers 6 are distributed in a tic-tac-toe shape at the top of the steel pipe 4, and a plurality of clearance grooves 11 are provided in the sleepers 6. The U-shaped bolts 7 are movably connected in the clearance grooves 11, and the top surfaces of the U-shaped bolts 7 are flush with the top surfaces of the clearance grooves 11. By providing the clearance grooves 11 and making the top surfaces of the U-shaped bolts 7 flush with the top surfaces of the clearance grooves 11, it is ensured that there is no bulge at the top of the entire support frame, thereby improving the stability of the bridge erecting machine when in use.

[0024] The usage method and working principle of the steel pipe support frame for the bridge widening bridge erection machine are as follows: first, a number of cushion stones are placed on the top of the cap beam 1, and then a number of embedded steel plates 3 are placed on the top of the cap beam 1 according to actual conditions. After the placement is completed, concrete is poured on the top of the cap beam 1 so that an integral cushion stone 2 can be formed on the top of the cap beam 1. In this process, it is necessary to ensure that the concrete poured between two adjacent cushion stones is flush with the cushion stones. Then, the steel pipe 4 is placed and welded to the top of the embedded steel plate 3. The stiffening steel plate 5 can not only provide additional support for the steel pipe 4, but also increase the contact and welding area between the steel pipe 4 and the embedded steel plate 3, which is beneficial to improve the stability of the steel pipe 4. Next, sleepers 6 are laid on the top of the steel pipe 4 according to actual needs. During the process of laying the sleepers 6, the sleepers 6 can be fixed to the steel The top of the pipe 4 is secured, thereby preventing the sleeper 6 from being displaced during use. The above steps can be used to complete the installation of the steel pipe support frame for the bridge widening bridge erecting machine, and the front legs of the bridge erecting machine are supported on the top of the existing bridge and the sleepers 6 for erection. Finally, all components can be inspected and accepted, thereby solving the problem that the length of the widened bridge cover beam 1 cannot meet the width requirement of the bridge erecting machine. It has strong applicability in actual engineering, and the whole installation process is simple and convenient. In terms of safety, the whole steel pipe support frame is easy to install and disassemble and has sufficient rigidity and structural stability. In terms of progress, the workers can install it quickly, the operation is simple, and the dismantling is safe and reliable, which can improve work efficiency. In terms of cost, the reuse rate of the steel pipe support frame is high in similar projects, and the cost of use can be saved compared to the floor-standing steel pipe support frame.
