Inclined shaft is a kind of engineering structure pattern being widely used in water-power plant conduit pipe system.Almost all of large-scale mixed flow Formula hydro-generating Unit or hydroenergy storage station all arrange the diversion steel pipe inclined shaft of major diameter, high inclination-angle.The safe condition of inclined shaft Operational reliability close relation with whole water-power plant.

This inclined shaft is generally after inlet gate well, and after hydroelectric station operation, large-sized power plant cannot be introduced into inclined shaft operation. Via gate shaft or spiral case enter the little micromachine utensil that manhole passes through then cannot meet major diameter, high inclination-angle steel pipe inclined shaft complete disconnected Face job requirements.Before this, scaffold must be manually built in comprehensive Inspection and maintenance operation of large hydropower station steel pipe inclined shaft;Cause Being limited by power scheduling, the power station time between overhauls(TBO) is the most comparatively short.So, for the whole country, large hydropower station steel Pipe inclined shaft can not carry out regularly Inspection and maintenance comprehensively always, is the blind area difficult point of power station safety management.

According to investigations, the engineering such as Liujiaxia Hydropower Station, the Yellow River, Xin'anjiang Hydropower Station has been run more than 50 year, and penstock alreadys more than Design life;The nineties in last century build power station " Five Golden Flowers " (Fujian Shuikou, Yunnan Man Wan, Guangxi Yan Tan, Hubei is every He Yan, Hunan the last five small stream) it is that the large number of large-scale hydroelectric project of representative has run more than 20 year, Yangtze River Gorges water conservancy The giant-scale engineering such as hinge, Xiaolangdi dam project on Yellow River has run more than 10 year, and these power station steel pipe inclined shafts all already more than National standard requires the cycle first comprehensively checked.Whether these large-scale steel pipe inclined shafts exist potential safety hazard, how to carry out comprehensively Examination and maintenance are constructed?This defines serious technological challenge to power station safety management.

Summary of the invention

For the problems referred to above, in conjunction with existing engineering machinery technology, this utility model provides one and is applicable to power station steel pipe inclined shaft The portable adjustable inclination angle hoistable platform of tunneling boring operation.It is characterized in that, including: portable bogie frame, adjustable inclination angle master put down Platform, hoistable platform, double-layer telescopic operation basket, under mark time basket, electric control system.Wherein:

Described portable bogie frame is the basis that this device is walked in steel pipe inclined shaft, is suitable to along at the bottom of the structure of inclined shaft axially-movable Seat and wheel rail system, bogie frame can be moved by external force traction, also can self-powered drive;

The main platform of described adjustable inclination angle is when inclined shaft change of pitch angle, and main platform is adjusted and bogie frame toggle clamp by levelling gear Angle also keeps the device of level;

Height adjustment equipment when described hoistable platform is to realize inclined shaft inner top operation;

Described double-layer telescopic operation basket is respectively arranged on main platform and hoistable platform, is used for the personnel that carry or operating apparatus To in the middle part of inclined shaft, the lateral operation in top time width adjustment positioning apparatus;

Basket of marking time under described facilitates personnel and utensil thereof to carrying out operation bottom inclined shaft;

This device is provided driven by power, instruction to control and safety assurance by described electric control system.

Therefore combining existing engineering machinery technology, this utility model carries out complete in the steel pipe inclined shaft of complicated pipeline, particularly high inclination-angle Section Inspection or safeguard that construction is unusual safety convenient.
