The horizontal climbing frame 6 is installed across the box girder end mold 1, and both ends of the horizontal climbing frame 6 are connected to the upper ends of the climbing frame beam 5 and the inclined climbing frame 7, respectively. The inclined climbing frame 7 is located on the side of the box girder end mold 1 away from the bracket, and the inclined climbing frame 7 has the same inclination direction as the box girder end mold 1. The lower end of the inclined climbing frame 7 abuts against the ground.

[0027] In this embodiment, combined with Figure 3 and Figure 4 As shown, a sliding connection assembly is provided at one end of the horizontal climbing frame 6 near the crossbeam 5. The sliding connection assembly includes a sliding sleeve 8, a locking post 9, and a spring 10. Both the horizontal climbing frame 6 and the inclined climbing frame 7 are ladder structures. The sliding sleeve 8 is fixedly connected to the end of the horizontal climbing frame 6 away from the inclined climbing frame 7. The sliding sleeve 8 is slidably fitted on the outside of the crossbeam 5. The sliding sleeve 8 can be a closed annular structure or an annular structure with an opening located on the side near the horizontal climbing frame 6. Multiple locking holes are evenly spaced along the length of the lower part of the crossbeam 5. A connecting plate 11 is fixedly connected to the sliding sleeve 8 below the bottom surface of the sliding sleeve 8. The locking post 9 slides through the bottom of the sliding sleeve 8 and the connecting plate 11 and is movably inserted into the locking hole. The spring 10 is located between the connecting plate 11 and the bottom surface of the sliding sleeve 8. Specifically, a limit plate is fixedly provided on the locking post 9, and the limit plate is located between the connecting plate 11 and the bottom surface of the sliding sleeve 8. The two ends of the spring 10 are fixedly connected to the limit plate and the connecting plate 11, respectively.

[0028] By pulling down the locking pin 9, the locking pin 9 disengages from the locking hole, pushing the horizontal climbing frame 6 to slide along the climbing frame beam 5.

Two hoisting beams 15 are respectively disposed on both sides of the column 4, with one end rotatably connected to the mounting plate 14. The electric hoist 16 is disposed on the hoisting beams 15. The rotation drive assembly is mounted on the mounting plate 14 and is used to drive the hoisting beams 15 to rotate. Specifically, the hoisting beam 15 is an I-beam structure, and the electric hoist 16 is a self-propelled electric hoist 16, so that the self-propelled electric hoist 16 can move back and forth along the hoisting beam 15 to change its position.

[0030] Specifically, such as Figure 5 As shown, the rotation drive assembly includes a motor 17, a drive gear 18, and a driven gear 19. The motor 17 is mounted on the mounting plate 14. The output shaft of the motor 17 passes through the mounting plate 14 and is fixedly connected to the drive gear 18. The lifting beam 15 is located below the mounting plate 14, and a rotating shaft is fixedly installed at one end near the column 4. The rotating shaft is vertically arranged and rotatably connected to the mounting plate 14. The driven gear 19 is fixedly sleeved on the rotating shaft and meshes with the drive gear 18. The motor 17 drives the drive gear 18 to rotate, thereby driving the driven gear 19, the rotating shaft, and the lifting beam 15 to rotate. By adjusting the angle of the lifting beam 15, and cooperating with the electric hoist 16 to change the connection position with the lifting beam 15, the installation of anchor plates at different positions can be adapted.

[0031] In this embodiment, the hoisting mechanism further includes a vertical pole 20 and a sleeve 22. The lower end of the vertical pole 20 passes through the mounting plate 14 and is fixedly connected to the rotating shaft. A diagonal cable 21 is provided between the upper end of the vertical pole 20 and the hoisting beam 15 to increase the stability of the hoisting beam 15. The sleeve 22 is sleeved on the outside of the vertical pole 20 and fixed to the top surface of the mounting plate 14, and the vertical pole 20 and the sleeve 22 are rotatably connected. Specifically, a bearing is provided between the rotating shaft and the mounting plate 14, and the sleeve 22 and the vertical pole 20 are rotatably connected through the bearing.

[0032] In this embodiment, the frame 2 is a trapezoidal frame structure constructed from several rods. The rods on the left and right sides of the frame 2 are side rods 201, which are inclined. The rods at the top and bottom ends of the frame 2 are top rods 202 and bottom rods 203, which are horizontally arranged. The support plate 3 is fixed to the top rod 202. A reinforcing rod 204 is also provided between the top rod 202 and the bottom rod 203. A movable fixing mechanism is provided on the inner side of the bottom of the frame 2. The movable fixing mechanism includes movable wheels 23 and a lifting drive assembly that drives the movable wheels 23 to rise and fall.

[0033] Specifically, the lifting drive assembly includes a fixed plate 26, a hydraulic cylinder 24, and a lifting plate 25. The fixed plate 26 is fixed to the inside of the base rod 203. The hydraulic cylinder 24 is mounted on the fixed plate 26, with its output end passing through the fixed plate 26. The lifting plate 25 is fixed to the output end of the hydraulic cylinder 24, and the moving wheels 23 are mounted on the bottom surface of the lifting plate 25. The hydraulic cylinder 24 drives the lifting plate 25 and the moving wheels 23 to rise and fall. When the moving wheels 23 lower and contact the ground, the lifting force of the hydraulic cylinder 24 causes the frame 2 to lift off the ground, facilitating the movement of the frame 2.

[0034] The working principle of the quick installation fixture for the box girder anchor plate in this embodiment is as follows:

[0035] By setting up a climbing frame, the horizontal climbing frame 6 is positioned across the box girder formwork to connect the climbing frame beam 5 and the inclined climbing frame 7.
