Automatic pushing system for detecting slender pipeline

The invention discloses an automatic pushing system for detecting a long and thin pipeline. The automatic pushing system comprises a PLC control system, an automatic take-up mechanism, a steel wire flexible shaft, a guide pipe, a motor driving system, a guide sleeve, a working gun and a probe. One end of the steel wire flexible shaft is connected with the automatic take-up mechanism, the other end of the automatic take-up mechanism penetrates through the guide pipe, the guide sleeve and the working gun to be connected with the probe, a motor driving system is arranged between the guide pipe and the guide sleeve, and a conveying belt on the motor driving system is matched with the steel wire flexible shaft and used for driving the steel wire flexible shaft to be conveyed forwards; the PLC control system is connected with the motor driving system and the automatic take-up mechanism, automatic operation is achieved through the PLC control system, two pipelines can be detected at the same time, and the automatic
