QTZ63型塔式起重機頂升機構(gòu)的研究及設(shè)計
摘 要 塔式起重機在現(xiàn)代化建設(shè)中起到非常重要的地位，它是現(xiàn)代社會進步的一個標(biāo)志，是人類建設(shè)不可缺少的重要設(shè)備。它的高效性、安全穩(wěn)定性是塔機行業(yè)較普遍關(guān)心和注意的問題。本設(shè)計就塔式起重機的頂升機構(gòu)的結(jié)構(gòu)、受力分析、核心受力件材料等幾個方面， 結(jié)合我國自行生產(chǎn)的QTZ63型塔式起重機為例，通過研究、分析踏步和頂升橫梁的受力情況，明確踏步和頂升橫梁的結(jié)構(gòu)和尺寸的確定方法，以及對套架關(guān)鍵尺寸的確定。以及根據(jù)頂升載荷確定頂升機構(gòu)的液壓系統(tǒng)。確保塔式起重機能夠安全、穩(wěn)定的實行頂升加節(jié)過程，保證塔式起重機的安全施工。

The Research and Design of How Tower Crane(QTZ63)rises
Abstract
The tower crane plays a very important role in modern construction. As an indispensable and important construction equipment, it is a marking of progress in modern society . In the crane area ,the crane’s high efficiently and safe stability is the key concern. With the example of tower crane QTZ63 made by China , this article introduces the rise structure of the tower crane, force analysis and the key component material. Through studying and analsing the force conditions of the tramper and top rising beam , make clear how to calculate and definite the dimensions and structure of top rising beam and tramper. So does the key size definition of frame. Make sure that tower crane can work safety , steady in its rising process, guarantee the safe construction of tower crane.
Keywords Rising mechanism Tramper Rising beam Safety stability
