A safety interlock method and interlock device for pipe end beveling machine

Abstract

The invention relates to the technical field of auxiliary systems for pipe end beveling machines, and discloses a safety interlock method and interlocking device for pipe end beveling machines. The interlocking device consists of a handle limit block, a positioning sleeve, a lock Pin, connecting sleeve, screw, and sliding sleeve connecting rod. One end of the two sliding sleeve connecting rods is connected with the two ends of the connecting sleeve through screws, and the other ends of the two sliding sleeve connecting rods are respectively worn on both sides. On the lock pin, the lock pins on both sides are respectively worn on the positioning sleeve fixed on the frame; the end of the lock pin on the switch valve side of the cutter head is corresponding to the limit hole of the handle limit block of the switch valve handle; The other end of the lock pin on the disc rotary switch valve side corresponds to the protective door. The invention has the advantages of simple and reliable structure, convenient installation and adjustment, low production cost, can force on-site operators to operate the equipment according to the specifications, and greatly improves the safety of the equipment during operation.

Description

technical field [0001] The invention relates to the technical field of auxiliary systems of a pipe end face beveling machine, in particular to a safety interlock method and an interlocking device for a pipe end face beveling machine. Background technique [0002] The pipe end beveling machine generally cuts the end face of the pipe through the rotation of the cutter head to perform beveling operations. The cutter head rotates at a high speed, and the cut iron chips are easy to wrap around the cutter and rotate with the cutter head. Therefore, when the equipment rotates, There is a certain risk. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the existing equipment, to provide a safety interlock method and interlock device for the pipe end face beveling machine, which can safely and reliably avoid the danger of injury when the equipment is working . [0004] In order to achieve the above-mentioned purpose of the i...
