Description
Technical field
Derrick safety work technical field is the utility model is related to, specifically relates to a kind of fall arrest dress for dismounting and mounting derrick
Put.
Background technology
For many years, when drilling well dismounts and mounts derrick operation, operating personnel in operation process, exists without fall protection equipment
The risk of operating personnel's falling from high altitude, serious threat human life safety.Since company sets up, make great efforts to be directed to solution always to tear open
Pacify derrick fall arrest protection risk, use for reference Shell Co. Ltd, external aloft work anti-falling lifeline, and purchase work high above the ground behaviour
Make the modes such as platform and attempt solve this problem, but this similar device and facility dismount and mount the operating mode of derrick with drilling crew and can not fitted
Should, therefore, fail effectively solve this risk.
Company leader office meeting, supervised and manage solution and dismounted and mounted derrick fall arrest protection problem, urge safety collar again in May, 2013
Protect energy-conservation portion and take the lead responsible, can solve this risk with relevant departments such as equipment departments, be responsible for pin item.Then related personnel sets about immediately
Organize investgation, go to the ground Field Research Drilling derricks such as Chongqing, bit company in Chinese Kai of the U.S., river Xisi, famous beauty in the late Spring and Autumn Period crew of Shell Co. Ltd
Dismount and mount falling proof device.Think after investigation：
1st, falling proof device weight used in the scene is fixed on derrick, often up to 40 kilograms with bolt clamping mode
Falling proof device is hung on or hung lower first on derrick, then with additionally mounted above and below derrick or dismounting, peace by secondary use crane
ETL estimated time of loading needs 10 minutes or so every time, and use is very inconvenient, and operating personnel is not without using therefore, using this mode yet.
2nd, the structure of the horizontal life line apparatus of triumphant bit company of the U.S. is along derrick by two fixed support bolts
It is fixed on derrick, then steel wire rope both ends is separately fixed on support, safety belt is tied on a steel cord by operating personnel, is risen
If to protective effect, but time-consuming for device installation, need to be 40~60 minutes, also, this mode is tied safety belt, if
When crossbeam need to be installed, the safety belt tail rope of operating personnel needs a large amount of growths, and the height of fall accordingly increases, fall injury
It can increase.Therefore, also without reference value.
3rd, Shell Co. Ltd is also without the falling proof device for being adapted to Drilling derrick to dismount and mount.
The content of the invention
The defects of the utility model is intended to present in above-mentioned prior art and deficiency, there is provided it is anti-fall that one kind dismounts and mounts derrick
