Abstract
The invention relates to a method for supporting tower outer ladder of wind generating set and an adjustable supporting device. A fixed stairway and the adjustable supporter are combined to form a floating supporter, and by utilizing the adjustability of the floating supporter, and according to the different conditions of foundation of an external wind power generating set stairway, the method adjusts the floating supporter, so that the floating supporter can be steadily supported on the foundation of the external wind power generating set stairway. The floating supporter is a bi-directionally adjustable supporter which is connected to the end part of a vertical external wind power generating set stairway plate, and can be rotated and extended, the rotatable part of the adjustable supporter can be directly rotated to be adapted to a different foundation-extended face, the extendable part of the adjustable supporter can be adjusted to adjust the height of the whole stairway when the foundation height is ununiform, and the bi-directional adjustment mode for angle and height ensures that different foundations and stairways can be in reasonable and safe contact.
Description
Technical field
The present invention is a kind of mounting type and structure of parts of wind power generating set, refers in particular to the outer terraced method for supporting of a kind of wind power generating set tower and support device, is mainly used in wind power generating set.
Background technique
In recent years, along with the rapid growth of China's economy, the contradiction of national power supply shortage is more and more outstanding, and except thermoelectricity, water power, wind-powered electricity generation is the most ripe renewable energy sources development and use and the commercialized development prospect is arranged most, so obtained development at a high speed.And along with the continuous increase of the wind-powered electricity generation power of the assembling unit, and the new architecture of various varying environment and load occurs, and produced various tower tube and basis accordingly.Because the architect of the outer ladder of wind-powered electricity generation unit tower tube and tower is that main engine factory, wind-powered electricity generation unit Base Design unit are designing institutees, foundation construction unit is generally local civil engineering team, and the third party that the prison unit of making on basis appoints for the owner, so the prior art drawbacks common has:
1. at different unit environment, main engine factory need design the outer ladder of tower of different heights and angle, and drawing lacks versatility;
2. cubic technology is linked up construction deviation not in place or normal in the practice of construction, all can cause the outer terraced leg of tower inconsistent with basic backfill face, and higher or backfill stone amount surpasses when specified when basic expanding surface, can cause the ladder superelevation, need cut tower terraced support plate outward; When on the low side or backfill stone amount is not enough when basic expanding surface, can cause ladder to fall less than ground, the bottom needs to fill up cement block, fragment of brick and sand hill etc.
These two kinds of defectives all both influenced attractive in appearance more potential safety hazard arranged, therefore need be improved this.
Summary of the invention
The objective of the invention is to the situation at different basic expanding surfaces and backfill stone amount, provide a kind of and can the self adaption different amount can regulate the outer terraced method for supporting of wind power generating set tower highly and support device again.
The technical solution adopted in the present invention is: the outer terraced method for supporting of a kind of wind power generating set tower, adopt the mode of fixed ladder and adjustable supporting device combination to form a kind of floating support device, utilize the controllability of floating support device, basic different situations according to the outer ladder of wind power generating set tower, regulate floating support device, make on the basis of floating support device energy firm support ladder outside the wind power generating set tower.Described floating support device is to connect one in the end of wind power generating set tower exterior stair riser both can rotate, the two-way adjustable supporting device that can also extend, the rotatable portion that can directly not rotate adjustable supporting device when basic expanding surface simultaneously adapts to, when height of foundation is inconsistent, can adjust the extending part of adjustable supporting device and adjust the ladder whole height, by existing angle bidirectional modulation mode is highly arranged again, guaranteed that different bases and stair can both have rationally and safe contacting; In order to prevent that support means bottom portion from skidding, be provided with anti-skidding line in the bottom of the extending part base plate of adjustable supporting device, increase surface of contact and improved Security.
The outer terraced adjustable supporting device of the wind power generating set tower that proposes according to said method, comprise generator set tower exterior stair riser, in wind power generating set tower exterior stair riser end, be connected with adjustable supporting device, adjustable supporting device comprises rotatable portion and extending part; Rotatable portion couples together by bearing pin and tower exterior stair riser bottom, and forming one can be around the hinge pin structure of bearing pin swing; Be connected with extending part in the bottom of rotatable portion, extending part comprises a vertical controlling mechanism at least, and vertical controlling mechanism can be according to the base case adjusting adjustable supporting device of the outer ladder of wind power generating set tower and the perpendicular distance between the basis; Vertical controlling mechanism can be threaded adjusting mechanism, also can be the turbine and worm controlling mechanism, all right Lever type controlling mechanism, or the lifting regulating mechanism of other machineries or hydraulic pressure.
When reality is used, require to select for use in tower exterior stair riser bottom the bearing pin of different-diameter according to different load-bearing, connect the adjustable supporting device adjustable supporting device, when can directly not rotating the adjustable supporting device leg simultaneously, basic expanding surface do not adapt to, when height of foundation is inconsistent, can rotate double-screw bolt and adjust the ladder whole height, this existing angle has the bidirectional modulation mode of height again, guaranteed that different bases and stair can both have rationally and safe contacting, the hexagon base plate is convenient rotation double-screw bolt both, and the anti-skidding line of bottom has increased surface of contact again and improved Security.All metal devices of product have all been done the hot galvanizing processing, guarantee antiseptic and rustproof.
The invention has the beneficial effects as follows that the blower foundation of different amount and height all can engage closely with the tower exterior stair, aesthetic property, versatility, Security obviously improve.
