Problems solved by technology
When turning the bending arm from the vertical state to one side, the operator needs to press down the turning bending arm and make it turn, and when the turning bending arm returns to the vertical state, the operator needs to pull up the turning bending arm and make it turn. It is easy for personnel to affect the speed of rotating the bending arm due to different proficiency, thereby affecting the accuracy of steel bar detection

Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0052] A steel wire repeated bending test device and a steel wire detection method, such as figure 1 As shown, it includes a base 1 along the horizontal direction, a base 2 is fixed on the top surface of the base 1, and one end of the base 2 is rotatably connected with a rotating shaft 21 along the horizontal direction, and the rotating shaft 21 rotates along its axis. The end of the rotating shaft 21 away from the base 2 is fixed with a rocking arm 3, the rocking arm 3 is arranged as a rectangular plate, and the rocking arm 3 is perpendicular to the rotating shaft 21, and the rocking arm 3 rotates along the axis of the rotating shaft 21 in the vertical plane. One end of the rocker arm 3 away from the rotating shaft 21 is fixed with an adjustment sleeve 31 , the adjustment sleeve 31 is arranged along the length direction of the rocker arm 3 , ...

The invention relates to a steel wire repeated bending test device and a steel wire detection method, belonging to the technical field of engineering detection, comprising a base, a base, a rotating shaft rotatably connected to one end of the base, a rocker arm fixed on the rotating shaft, and a The upper and lower mounting clamping mechanism, the upper mounting clamping mechanism and guiding mechanism set on the rocker arm, the positioning mechanism is set on the base, and the stabilizing mechanism is set on the rocking arm. block, the turning pulley supported on the rocking arm by rotation, the winding rope fixed on the installation block, one end of the winding rope goes around the turning pulley, passes through the base, and is fixedly provided with a counterweight through the base. By setting a stable mechanism on the rocker arm, not only the labor intensity of the operator is reduced, but also the reciprocating rotation rate of the rocker arm is more uniform, which improves the stability and practicability of its use. Straightening, so that the installation of the steel wire is more stable and the detection is more accurate.
Description
technical field [0001] The invention relates to the technical field of engineering detection, in particular to a steel wire repeated bending test device and a steel wire detection method. Background technique [0002] The repeated bending test of steel wire is a method to measure the plastic deformation ability of steel wire, detect the repeated bending resistance of steel wire and its covering layer, and display its defects. [0003] At present, the patent document with the authorized announcement date of 2017.05.17 and the authorized announcement number CN206177724U discloses a steel bar repeated bending test machine, which consists of a base, a rotating arm base, a roller fixing support, and a rotating bending arm. The arm base is screwed and fixed on the base and has a height-adjustable attachment hole facing the fixed support of the support roller. The fixed support of the support roller is fixed on one side and slidingly locked on the other side. The butt surface of t...
