Abstract

The utility model relates to an improvement of an industrial steel structure construction hoist, and particularly discloses a lifting bracket for installation. The lifting bracket comprises a bracket, a hoisting pulley and a hoisting rope, and is characterized in that the bracket comprises a supporting plate, reinforced ribs, ear plates, gudgeons, anchor bolts, bent ribs and a base plate; a rightward cantilever extending end is formed at the upper part of the supporting plate; the two ear plates are symmetrically welded on two sides of the rightward cantilever extending end; the gudgeons are installed on shaft holes of the two ear plates; the hoisting pulley and the hoisting rope are installed on the gudgeons; the two reinforced ribs are symmetrically welded on two sides in the middle of the supporting plate; the base plate is welded at the lower part of the supporting plate; connecting holes are distributed at four corners of the base plate and the four anchor bolts are installed at the four corners of the base plate; and the two bent ribs are also welded on the bottom surface of the base plate. The lifting bracket solves the problems of low production efficiency, high labor intensity and high potential safety hazards during the hoisting of small components in steel structure factory building construction, and is mainly used for the improvement of the steel structure construction hoist.

Description

A kind of installation lifting bracket

(1). technical field: the utility model relates to the transformation of Industrial Steel structure construction lifting facility, is a kind of installation lifting bracket.

(2). background technology: in the Industrial Steel structure construction of hydropower, the method for roofing small members lifting construction hoisting is: 1. utilized the hoisting crane lifting, 2. utilized and manually stand in men hoisting lifting on the roofing bead girder steel; The problem that these two kinds of construction method for hanging exist is: the hoisting crane lifting, and not enough with its length of boom of loop wheel machine of little hoisting capacity, with the loop wheel machine of big elevating capacity, the landing speed of loop wheel machine is slow again and cost is also higher; And, existing very big potential safety hazard with the artificial hanging method that directly promotes, efficient is low, labour intensity is big.

(3). summary of the invention: the purpose of this utility model is exactly to solve that the production efficiency that the lifting of steel-structure factory building construction small members exists is low, labour intensity reaches the big problem of production safety hidden danger greatly, and a kind of installation lifting bracket is provided.

Concrete scheme of the present utility model is: a kind of installation lifting bracket, it has support, gin wheel and lifting rope, it is characterized in that: described support is to be made of back plate, reinforced rib, otic placode, gudgeon, anchor bolt, bending muscle and bed plate, one cantilever external part is to the right arranged at the top of described back plate, the two sides of cantilever external part is symmetrically welded with two otic placodes to the right, on the axis hole of two otic placodes, gudgeon is installed, gin wheel and lifting rope are installed on gudgeon; Two sides at the back plate middle part is symmetrically welded with two reinforced ribs; Bottom at back plate is welded with bed plate, is furnished with connecting bore on four corners of described bed plate and four anchor bolts are installed, and also is welded with two bending muscle in the bottom surface of bed plate.

Principle of work of the present utility model is: the grasp of four anchor bolts edge of high-rise steel structure beam slab that linking closely on construction medium-height trestle bed plate is fixed on support on the high-rise support beam of steel structure; Support is the gin wheel and the lifting rope of cantilever external part to the right, one end of its rope and the lifting eye bolt of member are hung, the other end of rope is pulled by operating personal, and under the tension of rope, the member that rope institute bolt is hung rises to the installation site reposefully and installs.

Two reinforced ribs of the utility model support and two bending muscle can guarantee the lifting rigidity requirement of support, can fall the thickness of bottom support plate and bed plate to alleviate the weight of support simultaneously; Installation activity space when the external part of cantilever to the right of support can satisfy the lifting workpiece, gin wheel of installing on the cantilever external part gudgeon and lifting rope can make operating personal stand in above the ground tow lifting member just to the right; The utility model has solved steel-structure factory building preferably and has constructed that the production efficiency that middle-size and small-size lifting component exists is low, labour intensity reaches the big problem of potential safety hazard greatly, by the practice test of several large-scale steel structure roofworkss construction, the utility model shows has characteristics such as honest and clean, convenient and practical and safe and reliable at the bottom of structure tube list, the cost.

Fig. 1: the utility model structure master looks scheme drawing;

Fig. 2: scheme drawing is looked on the utility model structure left side;

Fig. 3: application note scheme drawing.

Among the figure: 1-otic placode, 2-gudgeon, 3-gin wheel, 4-lifting rope, 5-back plate, 6-reinforced rib, 7-anchor bolt, 8-bending muscle, 9-bed plate, 10-support, 11-steel structure support beam, 12-member.

(5). the specific embodiment:

Embodiment (seeing Fig. 1, Fig. 2 for details): a kind of installation lifting bracket, it has support 10, gin wheel 3 and lifting rope 4, particularly: described support 10 is to be made of back plate 5, reinforced rib 6, otic placode 1, gudgeon 2, anchor bolt 7, bending muscle 8 and bed plate 9, one cantilever external part is to the right arranged at the top of described back plate 5, the two sides of cantilever external part is symmetrically welded with two otic placodes 1 to the right, gudgeon 2 is installed on the axis hole of two otic placodes, gin wheel 3 and lifting rope 4 are installed on gudgeon 2; Be symmetrically welded with two reinforced ribs 6 on the two sides at back plate 5 middle parts; Be welded with bed plate 9 in the bottom of back plate, be furnished with connecting bore on four corners of described bed plate 9 and four anchor bolts 7 are installed, also be welded with two bending muscle 8 in the bottom surface of bed plate 9.

Application note (seeing Fig. 3 for details): the utility model is applied to the construction of certain steel structure roofworks lifting purlin member, be furnished with two cover lifting brackets 10 at the construction field (site), four anchor bolts of described support 10 are captiveed joint with steel structure support beam 11, two lifting eye bolts of one end of the lifting rope 4 of two supports 10 and member 12 are hung, the other end of lifting rope 4 is pulled by two operating personals, under the tension of lifting rope 4, the member 12 that lifting rope institute bolt is hung rises to the installation site reposefully and installs.
