Description
Technical field
The present invention relates to a kind of attachment type raise scaffold anti-drop device.
Background technology
The anti-drop device that existing attachment type raise scaffold uses, as patent 201420567548.X, patent 201420404231.4, patent 201420022927.0 patent, 201420032931.5, patent 201320600224.7 etc., though structure is different, but its anti-fall principle is all scaffold accidental falling triggers anti-drop device, anti-drop device withstands attachment type raise scaffold support body guide supporting block or short tube or other supporters, and support body falls termination.
This type of anti-drop device has following drawback: acceptor's attachment type raise scaffold support body guide rail structure, the conditions such as anti-drop device structure and anti-fall principle limit, main attachment type raise scaffold support body guide supporting block or short tube or other supporters must be at regular intervals, this spacing serves as the role of braking distance when support body falls, once there is scaffold accidental falling, anti-drop device is direct collision main attachment type raise scaffold support body guide rail when braking distance is larger, furthermore buffer time is extremely short, support body weight is large, the big security performance that not only greatly can reduce anti-drop device of its impact force, more severe patient also may make the support body of attachment type raise scaffold be out of shape, even building storey produces crack.
Summary of the invention
The impact force that when the present invention is intended to be reduced in accidental falling to greatest extent, attachment type raise scaffold comprises anti-drop device, support body guide rail produces, simultaneously shortening braking distance by a relatively large margin, improves the general safety level of attachment type raise scaffold construction.
Novel attached lifting scaffold voussoir anti-drop device of the present invention, primarily of anti-fall suspention main body, two anti-falling wedge block, inside connecting rod and outside connecting rod compositions, anti-fall suspention main body is primarily of trapezoidal groove and main body link plate composition, there is a trapezoidal groove (" recessed " shape semi-surrounding frame) that upper surface is large, lower surface is little anti-fall suspention main body side, the top of trapezoidal groove upper surface is main body link plate, main body link plate, by attached wall guide bracket boatswain chair and attached wall guide bracket assembly connection, is provided with a vertical chute in the middle of main body link plate.
Respectively there is guide rail groove medial surface both sides, the inclined-plane of two anti-falling wedge blocks respectively there is guide rail rail body 2, wherein any one is ridge for guide rail rail body 1 and guide rail rail body 2, the surplus next one is groove, guide rail rail body 1 and guide rail rail body 2 coordinate composition guide rail, when composition guide rail coordinates, the rubbing surface of two anti-falling wedge blocks is relative and parallel, the preferred dovetail groove of groove in its middle guide, also can be rectangular channel or dovetail groove, when guide rail rail body 1 be rectangular channel or dovetail groove time, voussoir one back side also has a groove or ridge, voussoir thus anti-falling wedge block can slide up and down along the guide rail rail body 1 of groove medial surface, rubbing surface preferably has upswept saw shape tooth or brake rubber block, increase and support body guide pass friction effect.Two anti-falling wedge block upper ends are all provided with hanger, and hanger it has pin-and-hole hinged respectively by hanger bearing pin and inside connecting rod, outside connecting rod.Inside connecting rod, outside connecting rod upper end are hinged by pitman pin, and pitman pin axle head stretches out, and coordinate, can realize sliding up and down along chute with the vertical chute in the middle of main body link plate, make two anti-falling wedge blocks and inside connecting rod, outside connecting rod can upper and lower synchronous slide.
Its anti-fall suspention main body is lifted on attached wall guide bracket by attached wall guide bracket boatswain chair, when attachment type raise scaffold promotes, support body guide rail moves upward, two anti-falling wedge blocks move upward, because of the effect of the guide rail rail body 1 of anti-fall suspention main body and inside connecting rod, outside connecting rod, two anti-falling wedge blocks synchronously open by transferring to the clamped condition of support body guide rail, and support body guide rail moves upward unaffected.When support body guide rail surprisingly declines, two anti-falling wedge blocks are also because the effect of inside connecting rod, outside connecting rod synchronously declines thereupon, again because of the effect of the guide rail rail body 1 of anti-fall suspention main body, two anti-falling wedge blocks transfer clamping support body guide rail to by opening, support body guide rail is fixed thereupon, and the support body completing attachment type raise scaffold is anti-fall.
Whole anti-fall process impact force is little, and braking distance is short, safe and reliable.
