22、和梯子， 塔设备被运到现场后，将塔水平的放在地面上，并将塔体垫起距离地面 2米，将预制好的平台和梯子以及护栏按照图纸安装就位。吊装的过程中由于吊耳和吊装钢丝绳的影响，在管式吊耳以上每层平台的某部分将受到 影响而不能安装到塔体上。剩余的部分等到塔体安装就位后再进行安装，具体方法是：塔体 未吊装前，将受影响不能安装的平台在塔体上的焊接护板先焊接到塔体上，同时将牛腿也焊 接到位，在塔体直立就位后，工作人员站在已安装好的同层平台上，挂好安全带，用吊车将 受到吊装影响的平台和它的栏杆吊装到已焊接好的牛腿位置，先将现安装的平台两边和原平 台的接触处对焊好， 然后将现在安装的平台和吊装前已安装好的牛腿焊接为

23、一体， 焊完一处， 再往前移到下一处，直至焊接完整个平台。In order to install flat roof and ladder of equipment maximum on the ground, when the equipment is moved to the site, the tower will been lay on the level ground, at the same time the tower will filled up 2m distance level to the ground, flat roof and ladder that have be

24、en made is installed to the tower body according to drawing. Because of affection of lifting lug and lifting rope, each flat roof some part from lifting lug to top will been limited, and cant been installed to the tower body. After the tower is installed to the ground, the leaving part will be insta

25、lled. Detail way is: before tower is installed, affecting welding protecting board of fiat roof first will be welded to the tower body, at the same time the cattle leg are welded to protecting board ， after the tower is installed to the ground. The workers stand on the flat roof that has been instal

26、led, at the same time work should tie safe belt，affecting flat roof and ladder will be installed to location with lifting crane, first two sides of later installing flat roof will be welded with two sides of installing flat roof that have been installed, and then the flat roof is welded to the cattl

27、e leg, after a set of the cattle leg is welded, and we can start to welded the next set of the cattle leg, until all of the cattle legs is welded.八、 eight. 垫铁和地脚螺栓 gasket of iron plate and anchor bolt1).地脚螺栓应配螺母和垫圈， 地脚螺栓应受力均匀。 Anchor bolt should be qualified the nut and gasket, the force on the anch

28、or bolt must be uniformity.2).每个地脚螺栓旁至少有一组垫铁，垫铁应尽量靠近地脚螺栓。 At least a set of gasket of ironplate is near the anchor bolt; gasket of iron plate should close with anchor bolt proximally.3).相邻两垫铁组的间的间距应为 500mm 左右。Space between Two sets of gasket of iron platethat is border should be around 500mm.4)每组垫铁一

29、般不超过四块，少用薄垫铁。放置平垫铁时，最厚的放在下面，最薄的放在中 间，设备找正后应互相点焊牢固。 Each set of doubler plate four block at most, thin doubler plate should be used little. when even double plate is placed, the thickest double plate must be placed underside and the thinnest double plate must be placed in middle, their spot welding m

30、ust be firm after equipment is seek position.5).每组垫铁均应放置平稳，接触良好，垫铁表面的油污应处理干净；塔体找正后，各组垫铁 均应被压紧，可用 0.25公斤手锤逐组敲击，听声音检查。Each set of double plate should be placed calmly and touched fully, the oil and dirt on the surface of double plate should be clean. After tower is centered align, each set of double plate should be pressed strictly, knock on the double plate according to order, we can check by sound.6)垫铁组高度：中小型设备 3060mm,大型设备50100mm；Height of stow-irons: for mid or min scale equipment is 30 60mm, for large scale equipment is 50
