Description

Quick-opening blind plate auxiliary tool Technical Field The application relates to the technical field of blind plate opening tools, in particular to a quick-opening blind plate auxiliary tool. Background The lock ring type quick-opening blind plate consists of a blind plate cover, a blind plate cylinder flange, a telescopic integral lock ring, a self-tightening lip-shaped seal ring, a door opening mechanism, a safety locking device and the like, as shown in figure 1. The existing opening mode is that after the replacement is qualified, the alarm screw is slowly screwed out when the equipment pressure is zero, then the alarm screw is screwed into the bolt hole of the insert, the insert is taken out as a handle, the stress application rod of the locking mechanism is pulled anticlockwise, the integral locking ring is contracted to the locking ring groove, the door operating mechanism is pulled outwards in a flat mode, and finally the blind plate is opened. The anti-corrosion device has the defects that when the anti-corrosion treatment is carried out on equipment, polished dust can enter the lock ring through the gap, paint can enter the lock ring through the gap during spraying, rust slag and dust are easy to accumulate in the lock ring and the lock ring groove, insufficient strength of the lock ring is easy to induce, and deformation is easy to occur after long-time operation. The locking ring is blocked and stuck, and the locking ring cannot be folded at the moment, so that the blind plate is difficult to open.
