Special tool for dismounting and mounting high-pressure vessel manhole door

Abstract

The utility model relates to a kind of high-pressure vessel manhole door special tool of dismounting, comprising: pole, two-dimensional linear bearing and bearing hanger;The inner ring of two-dimensional linear bearing is connected on pole, bearing hanger is respectively fixed on the outer ring of two-dimensional linear bearing;Bearing hanger is divided into two groups, one group of bearing hanger is set up upwards, another group of bearing hanger is set down;Pole is connected by support plate and manhole door.The utility model has beneficial effect: bearing hanger is all connected by two-dimensional linear bearing rotation on pole, reduce the friction between bearing hanger and pole, realize the front and back sliding and 360 ° rotation of bearing hanger on pole, solve the problem that the operation is particularly difficult in traditional method by sleeve connection exists large friction;Bearing hanger is provided with two groups, one group upwards, one group downwards, so that only through rope downward fixed hanger can realize manhole door weight balance, realize the improvement manhole door dismounting efficiency.
