Summary of the invention
The purpose of this utility model is to provide the inner integrated girder device of a kind of tower cylinder, this device is integrated into truss inside by cat ladder and elevator, cable testing bridge, illuminating system are fixed on to truss outside, make the easily damaged parts of tower cylinder inside all concentrate in the scope controlled at truss center, be convenient to follow-up maintenance and maintenance, reduce maintenance difficulty and maintenance cost.
The technical solution adopted in the utility model is:
The inner integrated girder device of a kind of tower cylinder, comprise square structure truss, be arranged at cable testing bridge on truss outside, be arranged at truss inner side cat ladder, be arranged at the elevator of truss inside and be arranged on the illuminating system on truss outer wall, described truss is comprised of more piece joist body, the quantity of described joist body is identical with the hop count of tower cylinder, the height of the tower cylinder of section is identical corresponding thereto respectively for the height of the described joist body of every joint, described upper and lower two joint joist bodies connect by guiding device, and the described joist body of every joint is all fixed on the inwall of tower cylinder by connection set.
Further, described guiding device comprises upper and lower guide sleeve and guiding harness cord, described upper and lower guide sleeve is fixedly connected with upper and lower joint joist body respectively, on the guiding harness cord of described upper guide sleeve top, be provided with adjusting nut, on the guiding harness cord of described lower guide sleeve below, be provided with lower adjusting nut.
Further, described connection set comprises the thread bush matching with tower cylinder, the adjusting bolt matching with thread bush, be fixed on successively lock washer and thin nut on the thread bush of tower cylinder inner side, between described thread bush and tower cylinder, is also provided with sealer.
Installation of the present utility model adopts segmented to install, along with each section of tower cylinder installed section by section; First according to the tapering of tower cylinder, regulate the distance of adjusting bolt and tower cylinder inwall to guarantee the concentricity of truss, after installing, first paragraph tower cylinder first segment joist body is fixed on first paragraph tower cylinder inwall by adjusting bolt and thread bush, and guiding harness cord being fixed in the guide sleeve at first segment joist body top by adjusting nut, and the height that according to circumstances suitably regulates guiding harness cord to stretch out; Then at second segment tower cylinder, dock with first paragraph tower cylinder fixing after, the guide sleeve of second section joist body bottom is enclosed within on guiding harness cord and fixing to complete the first joist body docking with adjusting nut; Install until there is joist body to install successively more.
Because the cylindrical shell of tower cylinder is generally cone structure, its diameter ratio topmost general little 1.5-2.5 rice of diameter bottom, and the utility model is in order to guarantee the concentricity of truss, adopt thread bush and the fixing mode of bolt, it not only can be according to the requirement that meets concentricity, but also avoided adopting the mode of welding between truss and tower cylinder, further reduce the internal stress of tower cylinder, improve the intensity of tower cylinder.In addition, in order to reduce tower cylinder and truss error in height, the utility model employing guiding device regulates the height of truss, not only simple and efficient, but also guarantees the intensity of truss.
The utility model has the advantages that: reasonable in design, not only quick and easy for installation but also intensity is high, cable testing bridge, illuminating system are fixed on to truss outside simultaneously, make the easily damaged parts of tower cylinder inside all concentrate in the scope controlled at truss center, be convenient to follow-up maintenance, reduce maintenance cost.
