Description

Anti-falling safety device for integral lifting scaffold

Technical Field

The present invention relates to the field of scaffolding and, more particularly, to devices.

Background

The scaffold is a construction equipment which is frequently used in building construction, decoration engineering and maintenance engineering. The attached lifting scaffold is mainly used for providing pedestrian passageways, discharging small amounts of piled materials and safety protection, and along with the acceleration of the pace of urban construction in China, high-rise and super high-rise buildings emerge in large quantities, the attached lifting scaffold is widely used, and meanwhile, the requirement on the safety of the attached lifting scaffold is higher and higher. The anti-falling block of the existing lifting scaffold is formed by pulling a needle swinging block through a spring, the spring is frequently used and is easy to age, so that the anti-falling effect cannot be achieved, the safety is low, or the anti-falling block is formed by two split gravity needle swinging blocks, the processing process is complex, and the combination difficulty is high.

The prior patent document with the publication number of CN104100077B provides a swinging needle type anti-falling wall-attached device, which is modified to be fixed on a wall surface through a wall-attached base, a guide rail of a scaffold frame body is matched into a slide rail of the wall-attached base, grid type anti-falling cross rods with uniform intervals are arranged on the guide rail of an attached scaffold, when the frame body is normally lifted, the anti-falling cross rods on the guide rail are engaged with a swinging needle to drive the swinging needle to move at a slow speed, an anti-falling block horizontally stretches and retracts under the traction of the swinging needle, the swinging needle resets under the action of a reset spring, the last movement is repeated under the action of the next anti-falling cross rod, when the frame body is abnormally lifted, namely the frame body is quickly fallen, the swinging needle is driven to rotate under the grid type anti-falling cross rods of the guide rail, the anti-falling block is driven by the swinging needle to move forwards horizontally and can not deeply enter into a neutral position of the grid type anti-falling cross rods to reset in time, and the anti-falling block of the guide rail, the guide rail is braked immediately, so that the anti-falling protection of the attached lifting scaffold is realized. Although the device has more beneficial effects, the following problems still exist: the device resets the pendulum needle through the spring, but the spring is ageing easily at the in-process that uses, leads to the pendulum needle can't reset completely, causes to prevent weighing down the piece and can't reset, leads to the unable normal going up and down of scaffold frame. In view of this, we propose a fall protection safety device for an integral lifting scaffold.
