Abstract

The present invention relates to a multiple self-locked elevation scaffold which is characterized in that each hanging point is provided with multi-channel automatic locking devices. An anti-fall device has the principle that the measurement to the hoisting weight of an electric hoist in the process of elevation determines whether the scaffold is locked; when the weight variation reaches a certain value, the multi-channel automatic locking devices simultaneously operate to lock the scaffold; the scaffold is locked, and simultaneously a power supply is automatically cut off. The elevation scaffold has the advantages of quick and stable elevation speed and stable and safe locking devices. The present invention is suitable for being constructed and used by any building structure.

Description

Multiple self-locked hoisting scaffold

The present invention relates to the external wall scaffold, especially a kind of hoisting scaffold with multiple self-locked function.

The scaffold that building operations is at present used has various ways: 1, basket-hanging scaffold, 2, the track lifting false work, 3, integral hoisting scaffold, 4, land the scaffold of setting up.There is following point in various degree in the scaffold of these types: 1, troublesome poeration, 2, cost height, 3, anti-fall measure mostly is friction-type, distance of glide is big, influence safety, 4, lack the weight prediction unit, though 5, anti-drop device has multiple tracks, but what automatically lock often has only together, and its safety is affected.

The object of the present invention is to provide a kind of hoisting velocity fast, has multiple self-locked function, the scaffold that effectively pre-fall arrest takes place, this kind scaffold can be predicted the variation of weight when promoting, when the scaffold weight change reaches certain value, multiple self-locked device is had an effect simultaneously, scaffold is locked rapidly, in the locking scaffold, cut off the electricity supply automatically, prevent the generation of falling, its anti-drop method is safe, effectively.

In order to achieve the above object, the scheme that the present invention adopts is: scaffold is established main frame, main frame is by anti-fall track, little cross bar, the main frame vertical rod in the cross binding and the outside fuses, and also fuse with the various rod members of scaffold, anti-fall track is opened a circular hole at a certain distance, pass the guiding device that is arranged at every floor from bottom to top, each guiding device all is provided with a lock rod, lock rod by the excellent spring holder of lock around, its rear end links together with the excellent handle of lock, horizontal control lever is positioned at the excellent handle of lock left side, and vertical control lever is connected with the horizontal control lever of each floor, and links to each other with portable plate, portable plate and suspension ring upper end weld together, suspension ring by the suspension ring spring holder around, when the suspension ring spring moves up and down, portable plate, vertical control lever, horizontal control lever also moves up and down, and controlling locking rod, thereby reaches the purpose that automatically locks from a plurality of points.In the outrigger outer end knife switch is installed, the knife switch of each suspension centre is together in series, and is cascaded with the starting switch of the control circuit of control electric block starting, knife switch with portable plate rise, descending disconnects and closure.

The present invention compares following outstanding advantage with existing scaffold technology: the function that 1, has multiple self-locked scaffold, 2, the weight prediction unit is arranged, control each floor locking device by the weight prediction unit, 3, adopt the lock rod anti-fall, bearing capacity is big, and is effective, and 4, descending operation is convenient, speed is fast, and 5, be fit to any building structure and use.

Below in conjunction with accompanying drawing, the present invention is described in further detail.
