Description

Technical Field

[0001] The utility model relates to the technical field of piling, in particular to a column piling straightening device. Background Art

[0002] In order to ensure that the column sinks vertically during piling, a column piling straightening device is needed to straighten the column. The current column piling straightening device uses a clamping component to vertically clamp the column. When the column sinks, the column piling straightening device as a whole cannot sink with the column, resulting in the heavy hammer hitting the column being easily blocked by the column piling straightening device, affecting the operation. For example, the disclosure (announcement) No.: CN216405231U, a highway guardrail column piling straightening device. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a column piling and straightening device, which is achieved by the following specific technical means: it includes a supporting bottom frame and a supporting top frame, the supporting top frame is located above the supporting bottom frame and the supporting bottom frame and the supporting top frame are connected by a folding arm assembly, when in use, the supporting bottom frame and the supporting top frame surround the outside of the column, a plurality of groups of extended support legs are evenly spaced around the circumference of the supporting bottom frame, a plurality of groups of straightening rollers are arranged around the inner circle of the supporting bottom frame, the straightening rollers are in rolling contact with the column, a plurality of groups of clamps are arranged around the inner circle of the supporting top frame, and the plurality of groups of clamps complete the clamping and fixing of the column, when the column sinks, the supporting top frame moves down accordingly, and the column is straightened and supported from top to bottom by the supporting top frame and the supporting bottom frame.

[0004] Preferred technical solution one: the folding arm assembly includes axis one, axis two, connecting arm one and connecting arm two, the axis one and axis two are respectively rotatably arranged on the supports on the sides of the supporting top frame and the supporting bottom frame, the connecting arm one and connecting arm two are respectively arranged on axis one and axis two and the ends of connecting arm one and connecting arm two are hinged.

[0005] Preferred technical solution 2: Notches are provided on the same side of the supporting bottom frame and the supporting top frame, and the notches are used for placing the columns.

[0006] Optimal technical solution three: a telescopic rod 1 is connected between the straightening roller and the supporting bottom frame.

[0007] Preferred technical solution four: the clamp is composed of a telescopic rod 2 arranged in the supporting top frame and a clamping plate arranged on the telescopic rod 2.

[0008] The above structure enables this solution to have the following beneficial effects:

[0009] 1. When in use, the support bottom frame and the support bottom frame respectively hoop the bottom and top of the column to straighten it. Compared with the straightening structure in a single position, the straightening structure in the upper and lower positions can further improve the straightening effect, especially the support bottom frame at the bottom is close to the ground, which effectively prevents the bottom end of the column from tilting when hammering;

[0010] 2. When in use, the support top frame is fixed to the column, and the support bottom frame limits the column. When hammering, the support top frame can sink synchronously with the column to avoid the overall height of the straightening device remaining unchanged when the column sinks, which affects the hammer striking action.
