Description
Technical field
Anti-falling safety device for construction lift detection technique field is the utility model is related to, more particularly to a kind of building hoist
Anti-falling safety device fixed point detection resets equipment.
Background technology
Building hoist is the construction elevator for workmen at the construction field (site), mainly aims at convenient construction personnel
Goods descending operation is carried out, because building hoist has the characteristics that loading capacity is big, lifting altitude is high, safe and reliable, is being built
Highly recognition is obtained in engineering, and is widely used, turns into the main construction machinery of skyscraper.Anti-falling safety device is that construction rises
Mostly important safety device in drop machine, its personal safety on workmen have direct influence.With skyscraper
Fast development, the use of the dual-purpose building hoist of people's goods is more and more, its exceed the speed limit safe fall-proof the problem of it is more and more prominent, therefore
Periodic inspection to Anti-falling safety device for construction lift is particularly important.According to JG121-2000《The building hoist cone of gears
Cydariform gradual anti-falling safety device》Standard requirement, safety must carry out exfactory inspection and periodically be examined in use
Test, the period of validity of periodic inspection must not exceed 2 years.The lift used at present in construction site is that be furnished with the cone of gears
The dual-purpose lift of people's goods of the rack pinion of cydariform gradual anti-falling safety device, cone of gears cydariform gradual anti-falling safety device
Mainly it is made up of gear, centrifugal speed-limiting device and cone three parts of drum brake.
The operation principle of cone of gears cydariform gradual anti-falling safety device is:When the objective of defense (construction elevator cage) is descending
Speed of service when reaching the responsiveness of demarcation, its centrifugal speed-limiting device gets rid of block displacement (suitable spine fixed claw), drives
Cone drum (suitable ratchet) is moved to brake band, contacted and produces braking moment, while disk spring group is compressed, and measures decrement
Size, by calculating braking distance when can determine whether its specified brake load.
The braking ability test method of safety is：Safety integral installation utilizes stepless speed-regulating device on testing stand
Safety is acted Deng testing equipment, automatic operation of recording speed and maximum braking moment, and print speed and braking moment are bent
Line.During experiment, the big nut and instruction pin of safety do not reset, but must answer centrifugation speed-limiting device after action every time
Position, when the maximum braking moment of measurement meets or exceeds braking moment calculated value, it can be regarded as an equivalent experiment, should now make
Big nut and instruction pin are resetted with specific purpose tool；In addition, when safety acts, safety switch is excited to act, it is electronic to cut off
The control circuit of machine and brake, after safety action, only by manually adjusting, it can just reset safety switch.
