Abstract

The utility model relates to a high-rising scaffold with an automatic anti-falling device. An anti-falling rod 15 is connected with the scaffold and rise and fall simultaneously with the scaffold. A cantilever beam 6 which hangs an electric block 21 is provided with a lock knife 9. A lock knife front spring 12 is arranged in front of the lock knife 9, and a lock knife back spring 10 and a lock knife pulling ring 11 are arranged at back of the lock knife 9. The rising or falling of the scaffold is guided through a guide ring 20. The lock knife 9 and the anti-falling rod 15 forms an automatic anti-falling system to achieve the anti-falling aim. The utility model has the advantages of high lifting speed, strong practicability, reasonable structure, convenient operation, and automatic anti-falling for the rising or falling and can meet the requirement of safe and rapid construction of a high-rising building.

Description

A kind of anti-fall highrise building scaffold automatically

The utility model is the highrise building scaffold, and especially a kind of energy is anti-fall highrise building scaffold automatically.

At present in the scaffold that uses, various ways is arranged: 1. basket-hanging scaffold, 2. the attached wall hoisting scaffold is 3. guide tracked from climbing scaffold, and 4. integral hoisting scaffold is 5. set up the overall height scaffold of roof from ground.The scaffold of these types exist to some extent use material many, from heavy, dismounting trouble, work efficiency is low, lifting means power big, be subjected to the integral construction condition restriction, lack and effectively automatically lock anti-drop device, scaffold valid function layer weak point such as less.

The purpose of this utility model provides that a kind of operation layer is many, hoisting velocity is fast, safe safe, the scaffold that can adapt to any different building structure, different construction requirements of processing ease, automatic anti-fall locking device.

Structure of the present utility model is anti-faller 15, fuse by anti-fall connecting rod 16 and scaffold, lock cutter 9 is installed in outrigger 6 outer ends, lock cutter front spring 12 and lock cutter rear spring 10 are installed in lock cutter both sides respectively, lock cutter draw ring 11 is pressed on the lock cutter, and its below hangs electric block 21, and guiding transverse tube 18 1 ends are fixed on the building 25, the other end is connected with guide ring 20 usefulness spiral shell selects, and guide ring 20 is enclosed within the outside of anti-faller 15.

The utility model has the advantages that 1. can adapt to any building structure requirement.2. save material 80-85%.3. promote easy and simple to handlely, labor intensive is few.4. hoisting velocity is fast, and the height that each lifting can reach two floors satisfies the rapid construction requirement.5. have rising, descend anti-fallly automatically, device preventing tilting guarantees construction safety automatically.6. scaffold is stressed rationally when promoting, and reduces eccentric moment.

Below in conjunction with accompanying drawing the utility model is described in further detail:
