Abstract

The invention discloses a four-connection-bar structure sliding door for a mill. The door comprises a door frame and a door cover. The door frame is connected with a door frame outer wall through welding and is connected with one end of the door cover, and the other end of the door cover is connected with the door frame outer wall through a four-connection-bar mechanism. The four-connection-bar mechanism comprises a first fixing bar, a second fixing bar, a first connection bar, a second connection bar, a first connection shaft, a second connection shaft and a third connection shaft. Respective location sleeves are arranged on the first connection shaft, the second connection shaft and the third connection shaft. External threads are arranged at the two ends of the first connection shaft, the second connection shaft and the third connection shaft. The first connection bar is connected with the second connection shaft, the third connection shaft and bolts through bolts and nuts respectively. The second connection bar is connected with the first connection shaft and the second connection shaft through bolts respectively. The door cover is connected with the first fixing bar of the four-connection-bar mechanism through welding, and the second fixing bar is connected with the door frame outer wall through welding. The door is convenient to open and close, good in seal performance and applicable to devices with heavy access doors.

Description

Technical field [0001] The invention relates to the technical field of mill equipment, in particular to a sliding door with a four-bar linkage structure for a mill. Background technique [0002] In the mill structure, many inspection holes or observation holes need to be designed as a door structure. On the one hand, it must be able to meet the sealing requirements of the mill, and on the other hand, it must be able to detect faults in the operation of the mill in time and take timely measures. To eliminate the fault. However, in the prior art mill access door structure, most of the door cover adopts a manual transport structure. The problem with this structure is: because there are more mill access doors and some door covers are relatively large. It is heavy, very inconvenient for disassembly and assembly, poor safety, and the operator's labor intensity is high. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems exis...
