Description

Technical Field

[0001] The utility model relates to the technical field of steel bar detection, in particular to a steel bar diameter detection device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. During the construction process, the quality of the rebar needs to be supervised, which requires the use of measuring devices to measure the diameter of the rebar.

[0003] The existing method of measuring the diameter of the steel bar is to use a vernier caliper to measure multiple locations and take the average value to record the diameter of the steel bar. However, due to the long length of the steel bar, it is very troublesome to measure multiple locations at the same time. At the same time, the existing detection device does not fix the steel bar, so the steel bar needs to be lifted for detection, which affects the detection speed. Therefore, a steel bar diameter detection device is proposed to solve the above problems. Utility Model Content

[0006] Preferably, a positioning block is fixed to the upper end of the base plate, and a tooth groove is provided at the bottom of the operating rod.

[0007] Preferably, a locking tooth is fixed to the upper end of the positioning block and the locking tooth is engaged with the tooth groove.

[0008] Preferably, a spring is fixed to the inner surface of the shell, and a folding plate is fixed to the other end of the spring opposite to the shell.

[0009] Preferably, a power motor is disposed on the surface of the base plate, and a threaded rod is transmission-connected to the surface of the power motor.

[0010] Preferably, the surface of the threaded rod is connected to a support frame through threaded rotation, a measuring meter is provided on the surface of the support frame, and a support block is fixed on the surface of the base plate.

[0011] Compared with the related art, the steel bar diameter detection device provided by the utility model has the following beneficial effects:

[0012] The utility model drives the movable sleeve to move in the movable groove through the operating rod, and the position of the movable sleeve can be quickly adjusted. The positioning block fixes the position of the operating rod, so that the fixed sleeve and the movable sleeve can stably fix the steel bar. At the same time, the power motor drives the measuring table to move, and various positions of the steel bar can be measured, thereby obtaining more detailed data of the steel bar.
