Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and particularly relates to a steel bar positioning and bending device for building construction projects. Background Technique

[0002] In building construction, reinforced concrete structures are the main components of buildings. Generally, steel bars need to be bundled into steel cages by steel bar hoops. Most of the shapes of the hoops are rectangular, and they are mainly made by bending steel bars with a steel bar bender.

[0003] Most of the existing steel bar benders only play the role of bending. For the bending position, that is, when bending multiple times, it is not easy to determine the distance between each bending point. The determination of the bending distance generally requires workers to measure manually, or place blocking objects on the bender for blocking and sizing, which is rather inconvenient. Therefore, we propose a bending device that can perform sizing bending. Content of the Utility Model

[0004] In order to achieve the above-mentioned utility model purpose and address the above technical problems, the utility model provides a steel bar positioning and bending device for building construction projects.

[0005] The technical solution is as follows: It includes a box body and a workbench installed on the box body. The characteristics are as follows: A turntable is rotatably connected to the upper surface of the workbench. A central column is rotatably connected to the upper surface of the turntable. A fixing plate is fixedly connected to the upper surface of the turntable. An adjusting mechanism is provided on the side surface of the fixing plate. The adjusting end of the adjusting mechanism is fixedly connected to a pressing plate. An installation strip is fixedly connected to the upper surface of the box body. An electric telescopic rod is fixedly installed on the back surface of the installation strip. The telescopic end of the electric telescopic rod is fixedly installed with a baffle. And an infrared distance sensor for detecting the moving distance of the baffle is embedded in the front surface of the installation strip. A PLC controller is fixedly connected to the upper surface of the box body. A connecting rod for driving the turntable to rotate is installed on the lower surface of the turntable. A driving component is installed on the surface of the connecting rod. And a rotary encoder fixed to the inner bottom wall of the box body is installed on the surface of the connecting rod.

[0006] Preferably, a fixing block is fixedly installed on the upper surface of the box body. A micro switch is fixedly connected to the back surface of the fixing block. A lapping block is fixedly connected to the surface of the turntable.

[0007] Preferably, the adjusting mechanism is specifically a threaded rod threadedly connected to the fixing plate. The end face of the threaded rod is rotatably connected to the side surface of the pressing plate. And the lower surface of the pressing plate is lapped with the upper surface of the turntable.

[0008] Preferably, the driving component includes a first gear fixedly installed on the surface of the connecting rod. A second gear driven by a motor is meshed with the surface of the first gear.

[0009] Preferably, the bottom end of the connecting rod is rotatably connected to the inner bottom wall of the box body, and a through hole for the connecting rod to pass through is provided on the upper surface of the box body.

[0010] Preferably, an indicator light is fixedly installed on the upper surface of the box body.

[0011] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows: when the distance reaches the value set on the PLC controller, the PLC controller turns off the electric telescopic rod, passes the steel bar through between the central column and the pressing plate, starts the motor, and the motor drives the connecting rod to rotate through the first gear and the second gear, thereby driving the turntable to rotate for bending. The rotary encoder detects the rotation angle, that is, the bending angle. When the angle reaches the angle set on the PLC controller, the PLC controller turns off the motor to complete the bending, so that the bending device can perform sizing bending and can control the bending angle. For the steel bar positioning and bending device used in the building construction project, when the motor rotates reversely, it can drive the turntable to return to its position. At this time, the overlapping block rotates with the turntable and overlaps with the microswitch, and the motor stops running, indicating that the turntable has successfully returned to its position. The setting of the indicator light, after the baffle moves to the specified position, the PLC controller simultaneously starts the indicator light to give a reminder, achieving the effect of convenient use.
