Abstract

The invention relates to a square steel tube lifting scaffold for high altitude operation of building construction, which is composed of lifting beams, a vertical main frame, a horizontal bearer frame, a scaffold body and anti-fall devices. The outside scaffold is characterized in that at least three lifting beams are arranged to integrally lift the whole scaffold; the anti-fall devices are arranged in the middle of the lifting beams; and an electric hoist is installed below the lifting beams for controlling the lift of the scaffold body. When the scaffold body is needed to be lifted, a hinge of the electric hoist is loosened, the electric hoist is started so as to lift the whole scaffold body. When lifted to the position, the electric hoist is fixed by the hinge, if the hinge for fixing the electric hoist is broken or cracked, the spring of the anti-fall devices which bears the weight of the electric hoist bounces, a wedge-shaped card falls down to clamp the main frame guide rail, thereby effectively preventing the whole scaffold body from falling.

2) main frame material: adopt the Q235 square steel pipe of 40 * 60 * 3.0mm, and the 6.3# channel-section steel.
3) lifting beam material: adopt Q235 10# channel-section steel.
, prefabricated support body parts
Support body divides inside and outside hurdle sheet, the hurdle sheet is at the prefabricated welding fabrication of processing factory, size has 1800 * 3000 and 1800 * 1,500 two kinds of main hurdle sheets, last layer is of a size of 1800 * 1500,1800 * 3000 cross arrangements, and lower one deck is of a size of 1800 * 3000, connecting sewing between last layer and lower one deck has just staggered like this, and the sheet soldering and sealing of outer hurdle connects gauze wire cloth.Every 6m or 4.5m spacing are provided with main frame, and the every joint of main frame is highly 4100.Also has the processing of the members such as lifting beam, falling proof device.
, the Assembling moulding
1) support body assembling
Inside and outside hurdle sheet connects into support body by cross bar with the M12 bolt, and every 6m or 4.5m form a standard block body by main frame, is all connected by the M12 bolt, is assembled into lifting frame body according to the building external form.
2) installation of guide rail, steel outrigger assembly
(1) the little cross bar on each step frame of guide assembly and main frame is connected, setting height(from bottom) is that following lifting girder steel assembly is basic point, guarantees that length that guide assembly reserves the girder steel assembly makes the height of a floor of support body rising.
(2) after having cleared up the first floor preformed hole, lower girder steel assembly is installed, by through-wall bolt, interior outer nut connects firmly with building with the girder steel assembly, and the screw thread that after nut screwing clamping, bolt head exposes nut end face is no less than 5 and detains; Link plate and the building surface of girder steel assembly are sturdy, and the guide wheel assembly of girder steel assembly termination will be enclosed within the gathering sill of guide assembly.
(3) install the girder steel assembly, with leading the beam wire rope, the end of the root of upper girder steel assembly and lower girder steel assembly is strained and tightened.
(4) cleared up the 3rd, the 4th layer of preformed hole after, install respectively the girder steel assembly by top requirement.
3) electric block is installed
Electric block hangs on the hanging board of girder steel assembly, connecting cable, electrical control cubicles.Concrete installation, debugging, maintenance, descending operation see the O﹠M manual of electric block and electrical control cubicles for details.
4), falling proof device is installed
Guide tracked Integral lifting outrigger falling proof device is set to an anti-fall wedge, and anti-fall wedge is arranged between wedge and guide assembly on lifting beam.Its operating principle is: when support body rose, because the gap between wedge and guide assembly is up big and down small, in the support body uphill process, the electric block chain tightened up, and spring bearer plate is pushed down anti-fall plate button naturally, and anti-fall wedge is raise automatically.In case gliding appears in support body, spring ejects, and anti-fall plate button is jumped out spring bearer plate automatically, and anti-fall wedge glides.Under the frictional force effect between wedge and guide assembly three, anti-fall wedge blocks tighter and tighter, thereby plays anti-fall effect, prevents support body further to glide, and its braking distance is not more than 8cm.Under the climbing frame inactive state, the electric block chain unclamps, and anti-fall wedge falls naturally.In the climbing frame decline stage, anti-fall wedge upwards promotes.
4, the lifting flow process of hoisting frame
1) remove the drawknot constraint of corresponding site;
Open the coupling component of support body and mounting platform when 2) promoting;
3) girder steel assembly, the support body with electric block and hoisting mechanism connects, circuit and switch board online intact;
4) pretension cucurbit chain;
5) open switch board, the operation switch board promotes button, makes hoisting frame rising first floor;
6) tension static state traction wire rope;
7) with support body and building phase drawknot, the electric block chain that comes loose, anti-drop device falls naturally, reaches the fall arrest effect.
8) follow-up lifting: lower girder steel assembly is pulled down upwards had enough to meet the need the two-layer set preformed hole place that is arranged on.
9) repeat above-mentioned 2-8 bar, complete successively promoting.
