Abstract

The invention relates to a steel bar bending auxiliary frame, in particular to a rotary excavating pile top steel bar bending auxiliary frame. The invention aims to provide the rotary excavating pile top steel bar bending auxiliary frame which is convenient to operate. The rotary excavating pile top steel bar bending auxiliary frame comprises a first bottom plate, a second bottom plate, contact plates, a moving mechanism and the like, the first bottom plate is located on the front side of the second bottom plate, the rear side of the first bottom plate makes contact with the front side of the second bottom plate, and the contact plates are arranged in the middle of the rear side of the first bottom plate and the middle of the front side of the second bottom plate correspondingly; and a moving mechanism for driving the bending press to move is arranged on the first bottom plate. According to the steel bar bending device, the limiting plate can limit and support the bending machine, then people can bend steel bars through the bending machine, the air cylinder serves as driving force to drive the bending machine to move upwards to be away from the steel bars, then the sliding block is manually moved, the bending machine can be driven to move to the position above the next steel bar, and operation is easy and convenient.

Description

technical field [0001] The invention relates to an auxiliary frame for bending of steel bars, in particular to an auxiliary frame for bending and bending of steel bars at the top of a rotary excavation pile. Background technique [0002] During the construction of bored piles, after the pile head is transferred and transported, it is necessary to use a hydraulic steel bending machine to quickly make a steel elbow at the pile head to ensure the concentric force of the steel bar and reduce the concrete cracks caused by the tensile deformation of the steel bar. [0003] Patent application CN113059081A, published on 20210702, discloses a pile head steel bar bending device with an accurate bending direction, including a positioning box, and the positioning box is provided with a positioning device for positioning the center position of the pile head from four directions, The side of the positioning box away from the ground is provided with a rotating device that can freely rotate...
