Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings.

[0030] During the driving process of the steel pipe piles of the steel trestle bridge, in order to ensure the stability and safety of the steel trestle bridge, generally, a support trestle bridge 9 is used for support. A steel pipe pile driving guide frame device provided in the present invention is also fixedly arranged on the support trestle bridge 9.

[0031] As Figures 1 - 5 shown, the present invention provides a steel pipe pile driving guide frame device for a steel trestle bridge, which includes a Bailey beam frame system, a positioning frame 6 and a guide frame limiting system. Among them, the positioning frame 6 is placed on the Bailey beam frame system, and the guide frame limiting system is fixedly connected to both ends of the bottom of the Bailey beam frame system. The Bailey beam frame system is used for the basic support of the steel trestle bridge and provides a construction platform. The positioning frame 6 is used to ensure the accuracy of the driving position and can determine the quantity according to the engineering requirements, so as to realize the rapid driving of the steel pipe piles 10 and improve the processing efficiency. The guide frame limiting system is used to fix the steel pipe pile driving guide device of the steel trestle bridge to the existing support trestle bridge 9 and determine the position and direction of the steel trestle bridge.

[0032] Specifically, as Figure 1 and Figure 3 shown, the Bailey beam frame system includes multiple groups of standard Bailey beams 1, multiple standard support frames 2, walkway boards 3, guardrails 4 and ladders 5. In this embodiment, 3 groups of standard Bailey beams 1 are provided. As Figure 2As shown in the figure, there is a set of standard Bailey beams 1. It should be noted that the length of the above-mentioned standard Bailey beams 1 needs to be determined according to the engineering requirements. The standard support frame 2 is perpendicular to the standard Bailey beam 1, and the standard support frame 2 is placed between every two groups of standard Bailey beams 1 and fixed by a pin shaft, so that the 3 groups of standard Bailey beams 1 are placed parallel and vertically. The walkway plate 3 is fixed on the top of the 3 groups of standard Bailey beams 1 by welding, and a plurality of positioning holes are opened on the walkway plate 3. The number and positions of the above-mentioned positioning holes correspond to those of the steel pipe piles 10 to be inserted. The guardrail 4 is fixed on both sides of the walkway plate 3 by bolts and connected to the standard Bailey beam 1. The ladder 5 is fixed at one end of the standard Bailey beam 1 by welding. In the Bailey beam frame system, the standard Bailey beam 1 and the standard support frame 2 are both existing construction materials, which are convenient to use and can save tooling costs. Among them, the standard Bailey beam 1 constitutes the main frame of the device, the standard support frame 2 is used to enhance the stability of the overall frame, the walkway plate 3 is used to provide a construction platform, the guardrail 4 is used to improve the construction safety, and the ladder 5 facilitates the construction personnel to go up and down between the support trestle 9 and the walkway plate 3.

[0033] As Figure 1 , Figure 4 and Figure 5 shown, the positioning frame 6 is fixed by welding on the edge of the positioning hole of the walkway plate 3. In this embodiment, the positioning frame 6 is in a square shape and is made of No. 10 channel steel. The square shape helps to reduce the deviation during the insertion process, ensure the accurate insertion of the steel pipe pile 10, and improve the accuracy and stability of the overall structure. The No. 10 channel steel has excellent mechanical properties and is convenient for processing. As a common building material, it can reduce the material cost on the premise of ensuring the quality. Through the guidance of the positioning frame 6, the insertion speed of the steel pipe pile 10 is accelerated and the construction efficiency is improved.

[0034] Specifically, as Figures 1 - 3 shown, the guide frame limit system is located at the head and tail ends of each group of standard Bailey beams 1, including a horizontal limit channel steel 7 and a plurality of vertical limit channel steels 8. The horizontal limit channel steel 7 passes through the 3 groups of standard Bailey beams 1, and the plurality of vertical limit channel steels 8 are perpendicular to the horizontal limit channel steel 7 and welded at both ends of the horizontal limit channel steel 7. The vertical limit channel steel 8 is fixedly connected to the support trestle 9. In this embodiment, there are 2 vertical limit channel steels 8, which are respectively fixed at both ends of the horizontal limit channel steel 7. Among them, the horizontal limit channel steel 7 is used to ensure that the guide frame limit system can be firmly fixed to the Bailey beam frame system and serves as the support foundation for the vertical limit channel steel 8, while the vertical limit channel steel 8 can fix the steel trestle steel pipe pile driving guide device to the support trestle 9 by welding to the deck of the support trestle 9.

[0035] The working principle of the present utility model:

[0036] Before construction, according to the construction requirements, prepare 3 sets of standard Bailey beams 1 with appropriate lengths. Connect multiple standard support frames 2 to the 3 sets of standard Bailey beams 1 with pin shafts to form a stable parallel vertical structure for the three sets of standard Bailey beams 1. Weld the walkway plates 3 on the standard Bailey beams 1, and install the guardrails 4 and ladders 5. According to the project requirements, use No. 10 channel steel to make multiple square-shaped positioning frames 6 and weld them on the positioning holes of the walkway plates 3 to complete the assembly of the steel trestle steel pipe pile driving guide device.

[0037] During construction, hoist the steel trestle steel pipe pile driving guide device as a whole. Pass two transverse limiting channel steels 7 through the first and last ends of the 3 sets of standard Bailey beams 1 respectively. Three vertical limiting channel steels 8 are perpendicular to the transverse limiting channel steels 7 and welded to both ends of the transverse limiting channel steels 7. Weld the vertical limiting channel steels 8 to the bridge deck of the branch trestle 9. After the device is fixed, hoist multiple steel pipe piles 10 and insert them into the positioning frames 6, and use a vibratory hammer to drive them in turn to achieve the rapid driving of multiple steel pipe piles 10.

[0038] After completion, remove the vertical limiting channel steels 8 from the branch trestle 9, hoist the device to the position of the next row of steel pipe piles 10, and carry out a new round of driving.

[0039] The above has described in detail an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention.
