[0015] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-6 As shown, a secondary through-hole No. 1 column anchoring device for a highway bridge erection machine includes: Two anchor beams 6; two anchor beams 6 are respectively abutted against the front and rear sides of the pad stone 12; the width of the anchor beam 6 is greater than the width of the pad stone 12, and both ends of the anchor beam 6 extend to the left and right sides respectively and set the pad stone 12; Two anchor rods 7; the two anchor rods 7 are respectively placed on the left and right sides of the pad stone 12, and correspondingly, through holes are provided in the front and rear directions of both ends of each anchor beam 6. After the anchor rods 7 pass through the through holes on the same side of the two anchor beams 6, the two ends are locked by locking nuts 8; Anchor rod 1; both ends of the anchor rod 1 are connected to the anchor beam 6 and the side wall of the bridge erection machine No. 1 column 13.

[0017] like Figure 1 and 3 As shown, the two ends of the anchor rod 1 are respectively hinged to the anchor beam 6 and the side wall of the bridge erection machine No. 1 column 13. The hinged connection assembly realizes flexible adjustment of the length of the anchor rod 1, can be applied to the bridge erection machine No. 1 column 13 of different specifications, and provides a large redundancy for the assembly, reducing the precision requirements of the components.

[0018] like Figure 3As shown, one end of the anchor rod 1 is connected to the middle of the anchor beam 6. The anchor rod 1 is connected to the middle of the anchor beam 6 to ensure stable support for the first column 13 of the bridge erection machine.

[0019] like Figure 1 As shown, the anchor rod 1 includes a threaded sleeve, a first screw rod, and a second screw rod. The first end of the first screw rod and the first end of the second screw rod are respectively threadedly connected to the two ends of the threaded sleeve. When adjusting the length of the anchor rod 1, the threaded sleeve can be rotated relative to the first screw rod and the second screw rod after installation.

[0020] like Figure 1 and 2 As shown, the anchoring device includes an upper hinge seat 2, an upper pin shaft 3, a lower pin shaft 4, and a lower hinge seat 5. The upper hinge seat 2 is welded to the side wall of the No. 1 column 13 of the bridge erection machine, and the lower hinge seat 5 is installed on the anchor beam 6. The second end of the first screw rod (with a twist lug) is rotatably connected to the upper hinge seat 2 through the upper pin shaft 3, and the second end of the second screw rod (with a twist lug) is rotatably connected to the lower hinge seat 5 through the lower pin shaft 4.

[0021] like Figure 2 and 3 As shown, the anchoring device includes a lower hinge seat rotating pin 10, which includes a head and a rod. The diameter of the head is larger than the diameter of the rod. The corresponding anchor beam 6 is formed into a boxed structure. A pin hole is provided at the top of the anchor beam 6. The diameter of the rod is slightly smaller than the diameter of the pin hole, and the diameter of the head is larger than the diameter of the pin hole. The head is placed in the anchor beam 6, and the rod passes upward through the pin hole and is connected to the bottom of the lower hinge seat 5. The provision of the lower hinge seat rotating pin 10 allows the lower hinge seat 5 to rotate horizontally. This structural design allows the upper hinge seat 2, the lower hinge seat 5, and the anchor rod 1 to have redundancy during installation, reducing the requirements for component accuracy and installation accuracy. It is used to allow relative rotation and connection when the axis of the lower hinge seat 5 and the first column 13 of the bridge erection machine do not coincide.

[0022] like Figure 2 As shown, the anchoring device includes an anchor plate 9 , which is provided with a through hole. The anchor plate 9 is arranged between the locking nut 8 and the anchor beam 6 , and the anchor rod 7 is arranged through the through hole in the anchor plate 9 .

In some embodiments, the friction plate 11 is a high-strength and wear-resistant rubber plate, which is used for leveling and increasing friction to provide anchoring force.

[0024] Taking the SDLB200t highway bridge erecting machine as an example, a specific implementation case is provided.

[0025] like Figure 1 、 2As shown in Figure 3, the anchoring device is constructed by installing anchor beams 6 before and after the pad stone 12, and installing friction plates 11 between the pad stone 12 and the anchor beams 6. The anchor rods 7 successively pass through the front and rear anchor beams 6 and are located on the left and right sides of the pad stone 12. Anchor plates 9 and locking nuts 8 are installed before and after the anchor rods 7, and the required torque is achieved by using a torque wrench. like Figure 4-6 Install the anchor rod 1 on the upper hinge seat 2 of the No. 1 column 13 of the bridge erecting machine through the upper pin shaft 3, then adjust the anchor rod 1 to an appropriate length, and install the lower end of the anchor rod 1 on the lower hinge seat 5 through the lower pin shaft 4. This completes the anchoring work of the No. 1 column 13 of the bridge erecting machine. The bridge erecting machine can then perform a second through-hole pass on the machine arm to achieve the beam erecting state.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
