Abstract
The utility model discloses a fall preventing device for lifting scaffolds, which is provided with a supporting base which is hinged with a deflector rod, and the front-lower part of the deflector rod is provided with a limiting support black; the lower end of the deflector rod is pulled with a spring, and the upper end of the deflector rod is pulled with a steel cable of which the other end is hung with a counterweight on the scaffold. The fall preventing device for lifting scaffolds of the utility model has the advantages of simple structure, convenient installation and operational safety, and the utility model is designed by adopting a lever equilibrium principle according to the characteristic that objects have force in weightlessness during falling down. When the lifting scaffold suddenly falls down and loses weight, the fall preventing deflector rod can be triggered instantly and the spring is compressed to make deflector rod extended out for firmly clamp the neutral position of the main frame of the scaffold so as to prevent the lifting scaffold from falling down.
Description
Technical field
The utility model relates to a kind of drop-proof device of lifting false work.
Background technology
Building, the especially construction of high-rise building all need scaffold erecting at the periphery of building in building course.Traditional scaffold is directly up to build from ground last layer one deck, needs a large amount of scaffolds like this, and needs stronger intensity for the scaffold of lower floor.Now adopt and begin to adopt raise scaffold, after scaffold was built, integral body can oscilaltion on building, to solve the shortcoming of above-mentioned scaffold.But the scaffold of this ascending/decending, tenesmus easily is so be badly in need of having a kind of device of scaffold tenesmus that can prevent to solve the problem of scaffold tenesmus.
Summary of the invention
It is a kind of simple in structure that the utility model provides, when preventing the scaffold drop-proof device of tenesmus suddenly.
The drop-proof device of lifting false work described in the utility model has a bearing, is hinged with a driving lever on bearing, in the front lower place of driving lever one spacing piece is arranged, spring has been drawn in the lower end of driving lever, and a wire rope has been drawn in the upper end, and an other end of wire rope is suspending a counterweight in midair on scaffold.
The drop-proof device of lifting false work described in the utility model, simple in structure, easy for installation, use reliably, adopt lever balance theory and the characteristics of the power of state of weightlessness design when dropping according to object.When lifting false work falls weightlessness suddenly, the driving lever of the anti-tenesmus of instantaneous trigger, the compression spring, driving lever stretches out, and firmly blocks the neutral of the main frame of scaffold, stops the lifting false work tenesmus.
Description of drawings
Fig. 1 is the structural representation of scaffold drop-proof device described in the utility model;
Fig. 2 is the vertical view of scaffold drop-proof device described in the utility model;
Fig. 2 is the use scheme of installation of scaffold drop-proof device described in the utility model.
The specific embodiment
As shown in Figure 1, 2, 3, wherein 1 is driving lever, and 2 is hanging ring screw, and 3 is pulley, and 4 is wire rope, 5 is pin, and 6 is pulley bracket, and 7 is bolt, and 10 is bearing, 11 is spring, and 12 is stub, and 13 are the plane pad, and 14 are cottor pin, 15 are cottor pin, and 16 is spacing piece, and 17 for being fixed on the pulley on the scaffold, and 18 is drop-proof device, 19 is building, and 20 is scaffold, and 21 is counterweight, and 22 is suspension hook, 23 is the spiral pull bar, and 24 is motor hoist, and 25 is the steel outrigger, and 26 is pre-embedded bolt.
Described lifting false work drop-proof device, one bearing 10 is arranged, on bearing 10, be hinged with a driving lever 1 by stub 12, in the front lower place of driving lever 1 one spacing piece 16 is arranged, spring 11 has been drawn in the lower end of driving lever 1, the upper end is provided with a hanging ring screw 2, and hanging ring screw 2 has drawn a wire rope 4, and an other end of wire rope 4 is suspending a counterweight 21 in midair by crossing the pulley 17 that is fixed on the pulley 3 on the bearing 10 and is fixed on the scaffold 20.
Under normal circumstances, counterweight is suspended on the scaffold 20 through wire rope 4, and driving lever 1 is subjected to the pulling force of the pulling force of wire rope 4 and spring 11 and perk is in a kind of lever balance state.When scaffold 20 drops suddenly, be suspended in also and then scaffold 20 tenesmus of counterweight 21 on the scaffold 20, wire rope 4 loses tension force and the pulling force of driving lever 1 upper end is disappeared, the lever balance state of driving lever 1 has been broken, and driving lever rotates counterclockwise under the pulling of spring 11, be pressed at last on spacing the piece 16, this moment, the front end of driving lever was protruding, and blocked the scaffold 20 of tenesmus, thereby stopped the tenesmus of scaffold.
