Description

Technical Field

[0002] The rebar sleeve, also known as the rebar joint, is a connecting piece used to connect rebars and has an internal thread corresponding to the thread head. The simple construction process is to use a rolling process to process the end of the rebar into a straight thread, and use the corresponding connecting sleeve to connect the two rebars to each other.

[0003] After the production of the rebar sleeve is completed, cracks may appear in the rebar sleeve. The occurrence of cracks will seriously affect the use of the rebar sleeve, so it is necessary to use a rebar sleeve crack detection device to detect the rebar sleeve. Most crack detection devices use ultrasonic waves for detection. Nowadays, rebar sleeve crack detection devices mostly use a conveyor belt to transmit the rebar sleeve to the bottom of the ultrasonic crack detection head for detection during batch detection. This transmission method is difficult to ensure the transmission stability of the rebar sleeve when transmitting the rebar sleeve, and it is easy to cause the rebar sleeve to deviate during transmission.
