Background technology
At wind power industry, generally cat ladder, power cable clamping plate or crane span structure, light conduits crane span structure, elevator decile are offered meter.But the tower diameter being as high-power wind-driven generator group is increasing (current 5MW, 6MW tower base diameter reaches 6 ~ 7 meters), tower inner cable quantity is more and more, cable clamp or crane span structure width also increasing, make partial cables more and more remote with the distance of cat ladder, cause that maintainer is difficult to the cable on cable clamp or crane span structure be safeguarded or keeps in repair on cat ladder, considerably increase follow-up maintenance difficulty and cost.Accordingly, it would be desirable to a kind of new technical scheme solves above-mentioned technical problem.
Summary of the invention
It is an object of the invention to provide a kind of tower and be internally integrated girder device, cat ladder and elevator are integrated into inside truss by this device, cable testing bridge, illuminator are fixed on outside truss, the consumable accessory within tower is made all to concentrate in the controllable scope at truss center, it is easy to follow-up maintenance and maintenance, reduces maintenance difficulty and maintenance cost.
The technical solution used in the present invention is:
A kind of tower is internally integrated girder device, including the truss of square structure, the cable testing bridge being arranged on outside truss, it is arranged at the cat ladder inside truss, is arranged at the elevator within truss and the illuminator being arranged on truss outer wall, described truss is made up of more piece joist body, the quantity of described joist body is identical with the hop count of tower, the height of the height difference tower of section corresponding thereto often saving described joist body is identical, described upper and lower two joint joist bodies are connected by guider, often save described joist body and are fixed on the inwall of tower each through connecting device.
Further, described guider includes upper and lower fairlead and guiding harness cord, described upper and lower fairlead is fixing with upper and lower joint joist body respectively to be connected, guiding harness cord above described upper fairlead is provided with adjusting nut, the guiding harness cord below described lower fairlead is provided with lower adjusting nut.
Further, the adjusting bolt that the thread bush that described connecting device includes matching with tower matches with thread bush, the lock washer being sequentially fixed on the thread bush inside tower and thin nut, it is additionally provided with fluid sealant between described thread bush and tower.
The installation of the present invention adopts stagewise to install, namely along with each section of tower is installed section by section；First the adjusting bolt distance with tower inwall is regulated to ensure the concentricity of truss according to the tapering of tower, by adjusting bolt and thread bush, first segment joist body is fixed on first paragraph tower inwall after first paragraph tower is installed, and be directed in the fairlead that harness cord is fixed on first segment joist body top by adjusting nut, and according to circumstances suitably regulate the height that guiding harness cord stretches out；Then second segment tower dock with first paragraph tower fixing after, the fairlead bottom second section joist body is enclosed within guiding harness cord and fixing to complete the first joist body docking with adjusting nut；Install till having joist body to install successively more.
Owing to the cylinder of tower is generally cone structure, its diameter little 1.5-2.5 rice more general than the diameter of bottom topmost, and the present invention is in order to ensure the concentricity of truss, adopt the mode that thread bush and bolt are fixed, it can not only according to the requirement meeting concentricity, but also avoid and between truss with tower, adopt the mode welded, reduce the internal stress of tower further, improve the intensity of tower.It addition, in order to reduce tower and truss error in height, the present invention adopts guider to regulate the height of truss, it is not only simple quick, but also ensures the intensity of truss.
The invention have the advantage that reasonable in design, not only quick and easy for installation but also intensity high, cable testing bridge, illuminator are fixed on outside truss so that the consumable accessory within tower all concentrates in the controllable scope at truss center simultaneously, it is easy to subsequent maintenance, reduces maintenance cost.
