Abstract

The utility model discloses an attached lifting scaffold which can play a role of automatically preventing dropping during lifting and is applied to high-rise building construction. Attached wall supporting bases of the attached lifting scaffold play a role of preventing inclination and dropping and stabilizing a frame body; a main support plays a role of carrying and supporting the frame body; the attached wall supporting bases are table body-shaped brackets; each bracket is formed by welding two right-angled trapezoidal steel plates and a rectangular steel plate; a concave dual-layer panel is welded at the top end of the bracket; guide wheels are arranged on the two sides of an opening of the dual-layer panel; a guide rail on the main supporting frame and a steel pipe frame are welded together through a steel plate; anti-drop rib blocks are uniformly welded in a guide rail groove; and an automatic anti-drop wheel clamping box is welded on a cross beam at the bottom of the main supporting frame. During implementation, the three attached wall supporting bases are vertically and fixedly arranged on a wall body at equal intervals by wall-penetrating bolts and the like, and the guide rail of the main supporting frame passes through the guide wheels on the attached wall supporting bases. An anti-drop pull rod is hung on a hanging ear on the bottom surface of the supporting panel at the lowermost part, and the lower end of the anti-drop pull rod passes through a hole of the automatic anti-drop wheel clamping box on the cross beam at the bottom of the main supporting frame. Under the action of a lifter, when the main support freely drops accidentally at any time in a lifting process, the dropping of the frame body can be stopped in a very short distance by the anti-drop pull rod and the automatic anti-drop wheel clamping box.

Description

Attached lift scaffold

Affiliated technical field:

The utility model relates to a kind of attached wall bearing (hereinafter to be referred as bearing), main backstop, anti-drop device of attached lift scaffold.

Background technology:

At present, the multiple pattern of the attached lift scaffold that uses in the construction market respectively has its characteristics: the bearing that has is welded into shaped steel, has plenty of with plate to be welded into, and main backstop separates with guide rail.The guide rail and the main backstop that have have coupled together, and often occur the guide rail distortion during up-down, and guide rail and bearing block not smooth easily mutually; And bearing can only play the effect of guiding, anti-dumping; Anti-fall dress system can only play automatic anti-fall effect when rising, and it is just not anti-fall automatically to descend, and anti-drop system can not automation; Defectives such as the workman operates cumbersome, and is not laborsaving, as not save time.

Summary of the invention:

For the main backstop that solves the attached lift scaffold that uses in the present construction market separates with guide rail, bearing is not provided with two-way automatic anti-drop device, operates defectives such as cumbersome.The utility model technology provides a kind of bearing and main backstop combination of attached lift scaffold, has up-down freely, and the two-way automatic anti-fall performance of going up and down is good, and the workman operates light, laborsaving timesaving characteristics.

The technical scheme that the utility model technology adopts is: bearing, main backstop are independent splits, cooperatively interact again, have played whole frame body and have gone up and down freely, automatically anti-dumping, anti-fall effect.The anti-drop device of whole frame body has two covers.One is enclosed within the cooperatively interact effect of the automatic anti-fall and firm support body when playing support body and rising of the anti-fall strut (hereinafter to be referred as " strut ") installed on the bearing panel and anti-fall muscle piece (hereinafter to be referred as " muscle piece ") in the main backstop guide rail.Another set of is that anti-fall on every Pin main backstop base cross members taken turns the anti-fall pull bar (hereinafter to be referred as " pull bar ") of grip box and bearing panel bottom surface bottom wearing extension and constituted automatic anti-drop device.

In bearing, the cantilever tip that the double-deck bearing panel of " recessed " font (hereinafter to be referred as " panel ") is welded on bearing stage body shape.Strut has been installed above the panel, and strut lower shaft bottom surface mid point is drilled with a hole, and compression spring and lock pearl are housed in the hole.On panel facing to the vertical ground auger in hole of strut lower shaft a same big circular hole.Sleeve pipe and thimble are housed in circular hole.The burn-on otic placode of two extension pull bars of the bottom surface of panel.

In main backstop, the muscle piece evenly is welded in the guide-track groove.Be welded with between guide rail and the steel framework of muscle piece and be welded into main backstop with the connection steel plate.The main backstop bottom crossbeam of burn-oning is welded with the anti-fall grip box of taking turns on the crossbeam.Three bearings and Pin main backstop combination in use.Three bearings are used the equidistant vertical installation of through-wall bolt respectively on the wall, and the guide rail on the main backstop passes three guide wheels on the bearing and goes up and down freely.The anti-fall effect automatically when rising of playing that cooperatively interacts of muscle piece in the guide rail and the strut on each bearing, main backstop rises and plays the effect of withstanding with firm main backstop when putting in place simultaneously.Main backstop strut in uphill process remains in the guide-track groove and slides under the effect of spring.If meet accident, strut will withstand the muscle piece in the guide-track groove automatically, prevents the main backstop free-falling.When main backstop descended, operating personnel moved strut to vertical with panel, and strut is pinned by the lock pearl in the lower shaft hole, becomes parallel shape with guide rail, and main backstop slowly descends, and can not receive any obstruction.The pull bar that a bearing panel of bottommost bottom surface hangs passes the wheel grip box, and the lower draw-bar of hoist hooks the suspension ring of main backstop base cross members, hooks the spring lever suspension ring of wheel grip box simultaneously.When hoist drove the main backstop up-down, pull bar shuttled back and forth freely in the wheel grip box.When main backstop meets accident, just the hoist lower draw-bar supports with lever out of handly to main, and the wheel in this hour wheel grip box is under the effect of spring, and moment is clamped pull bar, the free-falling of prevention main backstop.

In the wheel grip box, on two Internal baffles respectively vertically stem for stem two in the same way, with the bar hole of gradient.The wheel shaft of two U type sheaves passes the inclined-plane bar hole of Internal baffle.Wheel is sandwiched between two Internal baffles, welds two Internal baffles with an arc steel part to constitute integral body.The concave surface of arc steel part is relative with U type sheave, vertical respectively two horizontal bar holes stem for stem on two outer baffles, and the axle of U type sheave also passes the horizontal cylindrical void of outer baffle simultaneously.One end of two outer baffles and two Internal baffle one ends wear with axle, and outer baffle can sway.Two outer baffle other ends connect into integral body to the compression spring sleeve pipe with bolt.Spring moves up and down U type sheave with regard to driving outer baffle after putting into sleeve pipe along the beveled aperture on the Internal baffle, utilize the principle of inclined-plane locking, implements the anti-fall control of gliding.

The beneficial effect of the utility model is: can save 70% material, reduce the turnover expense, save 60% labour, can prevent automatically that support body from free falling taking place in any case, the workman has operated simply easily simultaneously, safe and applicable.
