Abstract
The utility model discloses an anti-falling device for an adhering lifting scaffold, which is provided with a supporting frame. One side of the supporting frame is fixed on an external wall of a building, and the other side is provided with two supporting arms. A steel shaft is provided between the two supporting arms. The central part of the steel shaft is provided with a radial through hole in which a sliding key is provided. The length of the sliding key is larger than the diameter of the steel shaft. An outer shaft sleeve is sleeved outside the sliding key part. The periphery of the outer shaft sleeve is provided with a plurality of radial teeth, and the inner wall is provided with a plurality of grooves and projected teeth. The lifting scaffold is longitudinally provided with a trapezoid frame. The crossbeam of the trapezoid frame is engaged with the teeth of the outer shaft sleeve. Two outward supporting beams of the supporting frame are provided with two sliding sleeves. The side surface of each sliding sleeve is provided with rollers. The sliding sleeves and the rollers are flexibly and slidably inserted into a slide rail on the scaffold. The anti-falling device for the adhering lifting scaffold is suitable for falling prevention of the adhering lifting scaffold in building construction, and furthermore has the following advantages: reasonable structure, high use convenience, high anti-falling effect, high safety and high reliability.
Description
Technical field
The utility model belongs to building operations implement technical field, a kind of being attached on building specifically, rise piecemeal carry out construction operation scaffold in lifting process, the device that when preventing that lifting appliance is malfunctioning and rupturing suddenly as the electric block jack, scaffold falls.
Technical background
In the high-building construction process, for preventing the generation of personnel and material falling from high altitude phenomenon, at present, generally adopt console mode scaffold Double all-sealed and layering to encorbelment.Adopt these measures, must set up operation in the high-altitude, brought again new potential safety hazard, and drop into also larger.Be attached to building itself by use, the layering echelon promotes the attached lift scaffold of constructing, and can effectively address the above problem.At present, the attached scaffold kind is more, and the characteristics of having nothing in common with each other use function unsound but mostly exist, and the safety problem when particularly promoting for this reason, needs to propose a kind of anti-drop device, makes it more safe and reliable.
The utility model content
The utility model provides a kind of anti-falling device of attached lifting scaffold for above-mentioned technical problem, and this device can guarantee the safety of attached lift scaffold when promoting effectively, prevents the generation of accidental falling accident.
the purpose of this utility model is achieved through the following technical solutions: anti-falling device of attached lifting scaffold, it is characterized in that: be provided with bracing frame, one side of this bracing frame fixedly secures on the outer wall of building, opposite side is provided with two outside support arms, be provided with a fixedly steel axle in the middle of this support arm, be provided with a radial through holes in the middle part of this steel axle, be provided with the feather key that radially slides of a perforation in open-work, this feather key one end is oval head, the other end is latch shape, the length of feather key is greater than the diameter of steel axle, surface cover has an outer shaft outside the middle feather key position of described steel axle, the periphery of this outer shaft is provided with several radially latches, be provided with radially alternately several grooves and double wedge at the inwall of outer shaft, the structure that arranges of this groove and double wedge is: when outer shaft slowly rotates on the steel axle, feather key is promoted by double wedge, the feather key two ends enter described groove successively, outer shaft smoothly rotates, when outer shaft moment turned soon, described double wedge withstood on the latch of feather key in groove outer shaft is blocked and can not rotate, vertically be provided with a ladder frame on described lifting false work, the crossbeam of this ladder frame is mutually meshing with the latch of described outer shaft.
The utility model further improves and the additional project of enforcement is:
Be provided with two sliding sleeves on two of support frame as described above outside support arms, the sliding sleeve side is provided with roller, and this sliding sleeve and roller are embedded in slide rail on described scaffold flexibly slidably.
Anti-drop device of the present utility model in use, bracing frame is fixed on the construction structure exterior wall, the latch of outer shaft is embedded in the ladder frame of scaffold, sliding sleeve embeds in the slide rail of scaffold.When the scaffold Slow lifting rose, the outer shaft of anti-drop device also slowly rotated thereupon, when the lifting appliance of scaffold malfunctioning, during tenesmus suddenly, outer shaft is stuck by the feather key of steel axle, and then by latch and the ladder frame of outer shaft, scaffold is blocked, and it is stopped falling.In order to insure, two or more anti-drop devices can be set, safety factor can be higher.
The beneficial effects of the utility model: anti-drop device of the present utility model is simple and reasonable, installs easily, and easy to use, the effect that anti-scaffold falls is very good, has fully guaranteed the safety of construction.
