Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model will be further described.

As shown in Figure 1 to Figure 3, a kind of erecting device for factory building construction high and medium structure, be made up of device body, described device body comprises the column 1 be symmetrically set, described column 1 is welded with oblique support bar 2, column 1 and support bar 2 are made up of steel plate or angle steel, the end portion of described column 1 and support bar 2 is fixed on the edge of a wing of roofing steel I-beam 12 by safeties, described safeties comprise the jig 13 and jig 14 that are provided with bayonet socket, wherein the shape of jig 13 bayonet socket is agreed with mutually with the top flange of steel I-beam 12, one end of jig 13 bayonet socket is provided with the set bolt 15 running through bayonet socket upper and lower end face, the shape of jig 14 bayonet socket is agreed with mutually with the side wing edge in steel I-beam 12 top flange, this bayonet socket end is provided with set bolt 16.

Described column 1 is disposed with suspension ring 4 and fixed pulley 3 from top to bottom, wherein suspension ring 4 are fixed on column 1 by welding manner, fixed pulley 3 both can be bolted to connection also can adopt and be welded and fixed, described suspension ring 4 are interconnected by wire rope 6 and the jack 5 that is connected with wire rope 6, jack 5 can select the hand of commercial type to pull chain etc. down, for tense wire rope 6, wire rope 6 is also provided with oblique pull wire rope 11, the other end of oblique pull wire rope 11 is connected with other fixtures, its objective is and prevent wire rope 6 and jack 5 from slot occurring, cause weight to drop instantaneously and cause security incident.Described fixed pulley 3 is interconnected by rope 10, rope 10 can be made up of the rope made of hemp or other materials, and the pulling that can circulate between fixed pulley 3, described wire rope 6 slidably connects movable pulley 7, described movable pulley 7 is with support 8, support 8 is fixedly connected with by improving bud grafting with rope 10, support 8 lower end be also provided with hook 9.

The treatment of details of the utility model in specific implementation process:

1, for pulley lifting heavy: the desirable assembly pulley of assembly pulley F=G/n, F=(G moves+G thing)/n, SF=n SG, vertical direction and horizontal direction principle phase, ignore the friction of wheel between centers, wherein n refers to as and is used in rope number of share of stock on movable pulley

2, the determination of support height, need leave certain interval with installation site during Components installation, and so this gap is just controlled by support height, but has certain amount of deflection to produce after steel wire hang weight; Amount of deflection detailed in theory calculates and uses calculus of variations catenary equation, is exactly specifically problem to be converted into solve a second order ordinary differential:

$\left\{\begin{array}{c}\frac{d^{2}y}{{\mathrm{dx}}^2}=a\sqrt{1+{\left(\frac{\mathrm{dy}}{\mathrm{dx}}\right)}^2}\\ y\left(0\right)=y_0\\ y^{\′}\left(0\right)=0\end{array}\right.$

Suitable Selecting All Parameters of solving an equation obtains

$y=\frac{1}{2a}(e^{\mathrm{ax}}+e^{-\mathrm{ax}}),$ Be catenary.

Calculation Method of Deflection also has engineering analog method, Hooke's law etc., but calculates more loaded down with trivial details, and in the utility model, wire rope amount of deflection takes estimation algorithm.

In work progress, the concrete implementation step of the utility model device is as follows:

1, install on steel roof joist when needing the component of translation, first determine the position of support column and support bar according to the spacing of this component and construction distance and single unit system is installed;

2, after device has been assembled, rope 10 is pulled to make movable pulley 7 move to the required member position installed.

3, on the hook 9 component colligation arranged on support 8.

4, after component colligation, pull rope 10, make component move to installation site, construction distance is shorter can two people be carried out, and longer, four people coordinate traction, connect and put.

5, iterative cycles 2,3,4 step, rear this device detachable of having constructed.
