Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hanging basket steel frames, in particular to a hanging basket steel sling high-precision adjusting structure. BACKGROUND

[0002] The hanging basket steel sling is a key structural component in bridge cantilever construction, mainly used for supporting and adjusting the elevation and position of the hanging basket, and is usually made of high-strength steel, such as finished rolled threaded steel, to ensure that it can withstand the huge load generated during construction. The adjustment of the elevation and position of the hanging basket is crucial to the construction precision and structural stability.

[0003] In the prior art, the steel sling is made of a thick steel plate with punched holes, and the load is supported by a bolt. The spacing of the sling holes is a fixed value, usually controlled at about 100 mm, so the minimum spacing for each adjustment is 100 mm.

[0004] In actual construction, there is no way to accurately adjust distances less than 100 mm. Usually, a jack is used to lift the steel plate under the support beam, and the thickness of the steel plate is adjusted multiple times to achieve a more accurate elevation. This method is not only cumbersome but also has low adjustment accuracy. CONTENT OF THE UTILITY MODEL

[0017] By adopting the above technical scheme, the moving cylinder moves up and down along the guide column under the adjustment of the height adjusting mechanism, so as to change the horizontal height relative to the beam and adjust the height of the steel hanging frame, and the movement of the moving plate in the horizontal direction is converted into the movement of the moving cylinder in the vertical direction through the connecting rod.

[0018] Optionally, the screw rod is provided with a limiting block at both ends, and the diameter of the limiting block is greater than the diameter of the screw rod.
