Abstract
The utility model discloses a fixed hoisting point part for the maintenance of outer walls of chimneys, which comprises a hoop, flanges and hoisting rings. The fixed hoisting point part is characterized in that the hoop is made of a piece of curved flat steel, the curving diameter of the hoop is equal to the outer diameter of the mounting part of a chimney, and the hoop is rounded into a ring on the horizontal plane. The flanges are respectively welded at positions 250 mm away from the ends on the outer sides of both ends of the flat steel of the hoop, and one hoisting ring is welded every 1200 mm on the outer side of the flat steel of the hoop. The flanges and the hoisting rings are perpendicularly welded along the radial lines of the circle center of the hoop. The flanges and the hoisting rings are cuboid components, the centers of which are respectively provided with a vertical slotted hole. A steel plate is cut into the flanges and the hoisting rings, and the flanges and the hoisting rings are respectively used for mounting the hoop and wire ropes and safety wire ropes for mounting and hoisting objects. The specifications and sizes of the flanges and the hoisting rings are equal, and the heights of the flanges and the hoisting rings are equal to the width of the flat steel of the hoop. The fixed hoisting point part has the advantage that the fixed hoisting point part is easy to fabricate and convenient to mount, does not destroy the outer wall of the chimney and is safe and reliable.
Description
Technical field
The utility model belongs to the overhaul of the equipments technical field, relates in particular to a kind of chimney outer wall maintenance construction suspension centre fixture.
Background technology
At present, the maintenance construction of chimney outer wall, its vertical transport suspension centre often utilizes on maintenance steel ladder on the chimney outer wall and does suspension centre, or fixedly suspension centre of expansion bolt is installed in boring on the chimney outer wall.Maintenance steel ladder corrosion in the open throughout the year is comparatively serious, and safe year, number can not reliably be estimated, did suspension centre with it and had potential safety hazard.The chimney outer wall is weathering to some extent in the high-altitude, and expansion bolt is installed destructible chimney outer wall, adopts expansion bolt larger in chimney outer wall fixed installation suspension centre potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of chimney outer wall maintenance construction suspension centre fixture is provided, and reaches and makes simply, and is easy for installation, do not destroy the chimney outer wall, safe and reliable purpose.
The purpose of this utility model is achieved like this: a kind of chimney outer wall maintenance construction suspension centre fixture comprises anchor ear, flange and suspension ring.It is characterized in that: described anchor ear adopts the band steel bending to make, and its bending diameter is identical with installation position chimney external diameter, surrounds an annulus on horizontal plane.A flange is respectively welded at 250mm place, lateral extent termination outside anchor ear band steel two ends, in the anchor ear band steel outside every suspension ring of 1200mm welding.Flange and suspension ring vertically weld along the radioactive ray in the anchor ear center of circle.
Described flange and suspension ring are the cuboid member, and its centre has a vertical slotted hole.Flange and suspension ring are cut into steel plate, be respectively used to install anchor ear and handling object wire rope and insurance steel cable are installed.
Described flange and suspension ring specification, in the same size, its height is identical with the width of anchor ear band steel.
before chimney outer wall maintenance construction suspension centre fixture is installed, operating personnel progressively fasten safety rope according to the rock-climbing mode when climbing up original cat ladder and inspection platform, again the handling of chimney outer wall maintenance construction suspension centre fixture is installed to the former steel platform of haveing been friends in the past, with the anchor ear hoop in the chimney appropriate location, pass slotted hole on the flange of two of left and right with full silk split bolt, pad respectively the lastblock billet again before and after full silk split bolt, fastening after nut is loaded onto in silk split bolt rear and front end entirely again, a full silk split bolt tighten up stressed after, the tight full silk split bolt in one side, on one side knocking the anchor ear surface with artificial hand hammer ties anchor ear and chimney outer wall to be adjacent to close, then anchor ear band steel two end joints are welded to each other firmly.
When chimney outer wall maintenance construction suspension centre fixture uses, first with wire rope loads onto clip, clamp with the special-purpose rope clamp of tetrad after the cable wire end inflection, then clip is buckled in the slotted hole of suspension ring, the lower end of wire rope is used for the handling of self lift type hanging basket or hanging safety belt.
Compared with prior art, the utility model has the advantages that: make simply, easy for installation, do not destroy the chimney outer wall, safe and reliable.
