Micro-adjustment device for improving elevation precision of hanging belt of bridge construction hanging basket

Abstract

The invention discloses a micro-adjustment device for improving elevation precision of a hanging belt of a bridge construction hanging basket. The micro-adjustment device comprises a cross beam, a through hole formed in the cross beam, a clamping seat arranged in the through hole and a micro-adjustment structure arranged in the through hole and used for controlling the clamping seat to move. The cross beam is separated from the clamping seat and can move relative to the clamping seat; the clamping seat is used for supporting a pin shaft, the fine adjustment structure is used for adjusting andcontrolling the clamping seat to move so as to adjust the height of the clamping seat, and therefore fine adjustment is achieved, the purpose of accurately controlling the elevation is achieved, elevation control is achieved through the structure, and tedious and potential safety hazards caused by repeated replacement of base plates with different thicknesses can be avoided.

Description

technical field

[0001] The invention relates to the field of bridge construction equipment, and more specifically relates to a micro-adjustment device for realizing the elevation accuracy of bridge construction hanging basket suspenders. Background technique

[0002] Bridge construction hanging basket is necessary equipment in bridge construction, and the sling is an important load-bearing part for hanging the lower steel structure tray, bottom mold, outer mold, inner mold, inner and outer sliding beams, etc. in the hanging basket. During construction, it is often necessary to adjust the elevation of the beam body in order to meet the elevation requirements of the bridge design. The sling is made of a thick steel plate with a row of holes, and is loaded by a pin. The spacing between the sling holes is 120mm, so the minimum spacing for each adjustment is 120mm, and there is no way to adjust it accurately. Therefore, the construction site often uses a jack to lift it up. The ...

Examples

Embodiment 1

[0024] like figure 1 A micro-adjustment device for realizing the lifting accuracy of the suspension belt of the bridge construction hanging basket is shown, including a crossbeam 1, a deck 2, and a fine-tuning structure. 2 and the beam 1 are separate structures and placed in the perforation to support the pin shaft 5; the fine-tuning structure is placed in the perforation to control the movement of the card holder in the perforation to achieve micro-adjustment of the elevation.

[0025] A groove can be arranged on the deck 2, and the groove matches the pin shaft.

Embodiment 2

[0027] Based on the principles of the above embodiments, such as Figure 1 to Figure 5 As shown, this embodiment discloses a specific implementation manner of a fine-tuning structure.

[0028] like figure 1 As shown, the fine-tuning structure adopts a screw, and the structure of the screw nut is a conventional structure. Specifically, it includes a screw 33 and a nut 31 sleeved on the screw 33. The nut 31 is fixed on the deck 2, and the nut 31 is placed in the perforation. , one end of its screw rod is placed outside the crossbeam 1 to facilitate the rotation of the operating screw rod;

[0029] Specifically, one piece or two pieces can be provided for the deck, and when only one piece is provided, only one end of the pin shaft can be supported, and its structure is unstable. Preferably, the deck has two pieces, and the distance between the two pieces is greater than The thickness of the sling, when used, such as figure 2 , 3 , Shown in 4, two decks 2 are respectively pla...
