Abstract
(B, ) manhole cover dismounting device for heat exchanger. General the setting in the great hydroecium side in space of manhole on the heat exchanger, because water side pressure dynamic height, so the thickness of manhole cover is thicker, weight is heavy, inconvenient dismouting. A manhole cover dismounting device for heat exchanger which constitutes and includes: play hanger plate (b) (b) 1 (b) (b), the hanger plate that rises be connected with sleeve pipe (b) (b) 2 (b) (b), the cover pipe box in connecting rod (b) (b) 3 (b) (b's) right -hand member portion, the connecting rod be connected with spanner (b) (b) 4 (b) (b), spanner one end install the retaining ring, rise to have a set of circular through -hole on the hanger plate, a set of circular through -hole be the linear type and arrange, sheathed tube center part processing have the concave groove, the semicircle centre of a circle department of left part of connecting rod the screw hole has, the right part of connecting rod circular through hole has, be close to the threaded blind hole of one side processing of circular through hole. The utility model discloses be applied to the dismouting of heat exchanger manhole cover. (B, )
Description
technical field:
the utility model relates to the provision for disengagement by manhole cover of a kind of heat exchanger, can handled easily, and safe and reliable manhole cover provision for disengagement.
background technology:
manhole on heat exchanger is generally arranged on larger hydroecium side, space, because water lateral pressure is high, so the thickness of manhole cover is thicker, and Heavy Weight, inconvenient dismounting, particularly self-energized seal form, the improper easy damage hydroecium internals of dismounting.Generally inside hydroecium, manhole cover adds in prior art and hinge, and the manpower and materials of each dismounting at substantial.
summary of the invention:
the purpose of this utility model is to provide the provision for disengagement by manhole cover of a kind of heat exchanger.
above-mentioned object is realized by following technical scheme:
the provision for disengagement by manhole cover of a kind of heat exchanger, its composition comprises: hoisting board, described hoisting board is connected with sleeve pipe, described casing pipe sleeve is in the right part of connecting rod, described connecting rod is connected with spanner, described spanner one end is provided with back-up ring, described hoisting board has one group of manhole, one group of described manhole linearly type arrangement, the centre of described sleeve pipe is processed with Baltimore groove, the circle centre position of the left part semicircle of described connecting rod has screwed hole, the right part of described connecting rod has circular through hole, tapped blind hole is processed with in the side near described circular through hole.
the provision for disengagement by manhole cover of described heat exchanger, described hoisting board is angle block of right angle, and the tapped blind hole on the Baltimore groove on described sleeve pipe and described connecting rod is bolted.
the provision for disengagement by manhole cover of described heat exchanger, described sleeve pipe is steel pipe, and described connecting rod is round steel, and described spanner is steel pipe.
the beneficial effects of the utility model:
1. the utility model adopts hoisting board, and be welded on sleeve pipe, Welding Structure is safe and reliable, can pass steel wire rope, lift by crane with crane in the circular hole of hoisting board upper end.
the utility model adopts connecting rod to be through in sleeve pipe, and the nut that tights a bolt on connecting rod, sleeve pipe can 90
o
rotate in angular region.
spanner is through in the circular port of connecting rod one end by the utility model, and connecting rod other end bolt and nut and manhole cover are fixed, by wrench operated connecting rod dismounting manhole cover.
the utility model structure easy accessibility, simple to operate, safe and reliable, greatly shorten the manhole cover dismounting cycle, shorten the overhaul of the equipments time simultaneously.
