The invention discloses an automatic clamping device for flaw detection of a steel
wire rope. The automatic clamping device comprises a
machine base, and a case and a rack
assembly, which are arranged on the
machine base; the case comprises a case body which is internally provided with a
solenoid valve connected with a PLC (
Programmable Logic Controller), a sliding rail is arranged on the
machine base and is used for enabling the case body to slide horizontally, and a clamping mechanism capable of clamping the steel
wire rope and the rack
assembly which can rotate relative to the case body and can carry out flaw detection are arranged above the case body; the rack
assembly comprises a guide mechanism and a probe arranged on the clamping assembly for carrying out flaw detection; the
solenoid valve drives an air cylinder to drive the case and the rack assembly to move towards the steel
wire rope, the
solenoid valve drives the air cylinder to drive the guide mechanism to be fitted on the steel wire
rope, and the solenoid valve drives the air cylinder to drive the probe on the clamping assembly to be opened and closed, therefore, the clamping and flaw detection operations to the steel wire
rope can be achieved. The automatic clamping device can completely realize automatic clamping, the self-
calibration function of the relative position of the probe and the steel wire
rope can be realized, remote monitoring can be realized by a
remote computer, and the safe and stable operation of the steel wire rope flaw detection
system can be ensured.
