Figure 1 and Figure 2The climbing frame for bridge piers includes a climbing frame body 1, an electric control box 4 and a motor 2 for connecting a steel wire rope. The climbing frame body 1 includes a fixed platform 101 and a connecting platform 102. Two fixed platforms 101 are relatively parallel. The longitudinal section of the fixed platform 101 is U-shaped to facilitate the standing of construction workers. The arrangement direction of the two fixed platforms 101 is parallel to the length direction of the fixed platform 101; the motor 2 corresponds to the fixed platform 101, and two motors 2 are symmetrically installed on each fixed platform 101 so that the steel wire rope can balance and drive the fixed platform 101 to rise and fall. The electric control box 4 is fixedly installed on any fixed platform 101.

[0029] Reference Figure 1 and Figure 2 Two connecting platforms 102 are relatively slidably arranged, and the arrangement direction of the two connecting platforms 102 is perpendicular to the arrangement direction of the two fixed platforms 101. The longitudinal section of the connecting platform 102 is U-shaped, and the cross-section of the connecting platform 102 is also U-shaped. The two ends of the U-shaped connecting platform 102 are respectively slidably connected with the two fixed platforms 101. The connecting platform 102 is located below the fixed platform 101. An inverted L-shaped hook 8 is fixed to the top wall of the connecting platform 102. The hook 8 is engaged with the top wall of the fixed platform 101, so that the connecting platform 102 is not easily separated from the fixed platform 101; the two fixed platforms 101 and the two connecting platforms 102 form a closed rectangular ring, and an adjusting component 3 for adjusting the two connecting platforms 102 to move closer or farther away from each other is provided on the fixed platform 101. The adjusting component 3 and the motor 2 are electrically connected to the electric control box 4. The electric control box 4 is manipulated to make the motor 2 and the adjusting component 3 work, which provides convenience for the operation of the construction personnel.

[0030] During construction, the two connecting platforms 102 are adjusted to move closer or further away from each other by adjusting the adjustment component 3, which helps to reduce or increase the length of the entire climbing frame body 1, and thus can be applied to bridge piers with different cross-sectional sizes or variable cross-sections, thereby expanding the scope of application to a certain extent.

[0031] Reference Figure 2 and Figure 3 In order to facilitate the adjustment of the two connecting platforms 102 to move closer to or farther away from each other, two support plates 9 are relatively fixed on the bottom wall of the fixed platform 101. The adjustment component 3 includes a bidirectional screw 31 and a driving member 32. The bidirectional screw 31 rotates and penetrates the two support plates 9 on the bottom wall of the fixed platform 101. The rotation axis of the bidirectional screw 31 is parallel to the arrangement direction of the two connecting platforms 102; a slider 10 is fixed to the bottom wall of the connecting platform 102 close to one end of the fixed platform 101, and the two sliders 10 at the same end of the two connecting platforms 102 are respectively threadedly connected to the two ends of the bidirectional screw 31 on the corresponding side. The driving member 32 is arranged on the bottom wall of the fixed platform 101, and the driving member 32 is used to drive the bidirectional screw 31 to rotate.

[0032] Reference Figure 2 and Figure 3 In order to facilitate driving the bidirectional screw 31 to rotate, the driving member 32 includes a motor 321, a first gear 322 and a second gear 323. The motor 321 is fixedly mounted on the bottom wall of the fixed platform 101. The first gear 322 is coaxially fixedly connected to the output shaft of the motor 321. The second gear 323 is fixedly sleeved on the middle part of the bidirectional screw 31. The first gear 322 is meshed with the second gear 323. The motor 321 is electrically connected to the electric control box 4, which helps to centrally control the use of the motor 321 through the electric control box 4.

[0033] When it is necessary to adjust the two connecting platforms 102 to move closer to or farther away from each other, the motors 321 on the two fixed platforms 101 are started at the same time. The two motors 321 drive the corresponding first gears 322 to rotate, and the first gear 322 drives the second gear 323 to rotate. The second gear 323 drives the bidirectional screw 31 to rotate in the same direction. The rotation of the bidirectional screw 31 drives the two sliders 10 to move closer to or farther away from each other, so that the slider 10 drives the corresponding connecting platform 102 to slide in the direction of approaching or moving away from the fixed platform 101, which helps to reduce or expand the length of the entire climbing frame body 1, so as to adapt to rectangular cross-section bridge piers of different sizes.

[0034] Reference Figure 2 and Figure 4 , an arc-shaped bonding plate 5 and a straight bonding plate 6 are slidably arranged on the connecting platform 102, the arc-shaped bonding plate 5 and the straight bonding plate 6 are arranged in the vertical direction, and the arc-shaped bonding plate 5 is located above the straight bonding plate 6, the arc-shaped bonding plate 5 bulges outward in the direction away from the fixed platform 101, and the arc-shaped bonding plate 5 and the straight bonding plate 6 are both used to abut against the side of the bridge pier, and the sliding directions of the arc-shaped bonding plate 5 and the straight bonding plate 6 are parallel to the arrangement direction of the two connecting platforms 102, and the arc-shaped bonding plate 5 and the straight bonding plate 6 are both located between the two fixed platforms 101, and sliding parts for driving the arc-shaped bonding plate 5 and the straight bonding plate 6 to slide are respectively provided on the connecting platform 102.

[0035] Reference Figure 2 and Figure 4 The sliding part includes a cylinder 7 installed on the connecting platform 102, the arc-shaped bonding plate 5 and the straight bonding plate 6 correspond to the two cylinders 7, the two cylinders 7 corresponding to the straight bonding plate 6 are fixedly installed on the bottom wall of the connecting platform 102, the two cylinders 7 corresponding to the arc-shaped bonding plate 5 are embedded in the bottom wall of the connecting platform 102, the extension direction of the cylinder 7 is parallel to the arrangement direction of the two connecting platforms 102, the arc-shaped bonding plate 5 and the straight bonding plate 6 are respectively hinged to the piston rod of the corresponding cylinder 7 through a hinge shaft, the hinge axis of the arc-shaped bonding plate 5 and the straight bonding plate 6 are parallel to the arrangement direction of the two fixed platforms 101, and the cylinder 7 is electrically connected to the electric control box 4.

[0036] When the side of the bridge pier is curved, start the two cylinders 7 corresponding to the curved bonding plate 5, and the corresponding cylinders 7 drive the curved bonding plate 5 to slide in the direction close to the fixed platform 101, so that the curved bonding plate 5 abuts against the side wall of the bridge pier; start the two cylinders 7 corresponding to the straight bonding plate 6, and the corresponding two cylinders 7 drive the straight bonding plate 6 to slide in the direction away from the fixed platform 101, so that the straight bonding plate 6 is located on the side of the curved bonding plate 5 away from the fixed platform 101, which helps to maintain the stability of the climbing frame body 1 and is suitable for bridge piers with curved surfaces on both sides.

[0037] When the side of the bridge pier is a plane, the two cylinders 7 corresponding to the straight bonding plate 6 are started, and the corresponding two cylinders 7 drive the straight bonding plate 6 to slide in the direction close to the fixed platform 101, so that the straight bonding plate 6 abuts against the side plane of the bridge pier, and the two cylinders 7 corresponding to the arc bonding plate 5 are started, and the corresponding cylinders 7 drive the arc bonding plate 5 to slide in the direction away from the fixed platform 101, so that the arc bonding plate 5 is separated from the side wall of the bridge pier, so that it can be applied to bridge piers with flat sides, and then can be adapted to bridge piers with different cross sections, further expanding the scope of application. Since the straight bonding plate 6 and the arc bonding plate 5 are hingedly arranged, they can adapt to the inclined surface at the variable cross section.

[0038] The implementation principle of the embodiment of the present application is: during construction, the motors 321 on the two fixed platforms 101 are started at the same time, the two motors 321 drive the corresponding first gears 322 to rotate, the first gear 322 drives the second gear 323 to rotate, and the second gear 323 drives the bidirectional screw 31 to rotate in the same direction, and the rotation of the bidirectional screw 31 drives the two sliders 10 to move closer to or away from each other, so that the slider 10 drives the corresponding connecting platform 102 to slide in the direction of approaching or moving away from the fixed platform 101, which helps to reduce or increase the length of the climbing frame body 1, and adjust the position of the connecting platform 102 according to the actual cross-sectional size of the bridge pier; then, according to the side shape of the bridge pier, choose whether to adjust the arc-shaped bonding plate 5 or the straight bonding plate 6 to move in the direction close to the fixed platform 101 to abut the side of the bridge pier, so as to facilitate use on bridge piers with different cross-sectional sizes, thereby expanding the scope of application to a certain extent.
