Description

Technical Field

[0001] The invention relates to the technical field of scaffolds, in particular to a full-rigid attached lifting scaffold with a lifting and lowering operating protection platform on the top. Background Art

[0002] The all-steel attached lifting scaffold is a high-rise building construction scaffold consisting of a vertical main frame, a horizontal support frame, a frame structure, an attachment device lifting mechanism and a synchronous lifting control system. The vertical main frame of the scaffold is a plane frame structure, which is composed of guide rails, external poles, main frame rigid brackets and bottom cross bars; the horizontal support truss is composed of web bars, frame poles, scaffolding boards, rigid brackets and bottom cross bars, which are set at the bottom of the frame; the frame structure is composed of frame poles, scaffolding boards, rigid brackets and protective nets. The protective net is connected to the external poles of the frame through connectors. Each component is connected by bolts.

[0003] The lifting mechanism of the scaffolding consists of an electric hoist, a lifting support, upper and lower lifting blocks and auxiliary vertical poles. The electric hoist is hung on the upper lifting block between the vertical main frame and the auxiliary vertical pole, and the wire rope is connected to the wall-attached lifting support through the guide pulley of the lower lifting block. The wall-attached lifting support and the wall-attached support are fixed to the building structure with double screws.

[0004] The swing block anti-fall device of the scaffold consists of an anti-fall swing block, a trigger block, a reset spring and a 30mm anti-fall pin. When the frame rises, the trigger block swings under the drive of the guide rail anti-fall tooth plate and resets under the action of the spring; when the frame descends, the trigger block drives the anti-fall swing block to swing, and the anti-fall swing block resets under the action of its own weight and the reset spring; when the frame falls, the reset speed of the anti-fall swing block is lower than the falling speed of the frame, and it supports the anti-fall tooth plate to achieve the anti-fall function.

[0005] The height of this type of frame is designed according to the building height, which can meet the protection requirements of 4-5 floors. However, with the diversification of high-rise building functions, the height of the main structure changes frequently. When the local height is higher than the design standard height, the frame protection height may be insufficient. When the height increases or decreases, the frame needs to be erected or dismantled at high altitude, which has high safety risks, high work intensity, and a relatively long construction period.
