部分章节示例如下:

4.1 整机性能 Overall Performance

整机性能参数包括公称起重力矩、最大工作幅度、最大起重量、最大工作高度、工作速度等。这些参数是反映一台塔机的工作能力大小,工作效率高低的重要指标。具体性能参数附后。

The Overall Performance includes Rated Hoisting Moment, Max Working Radius, Max Hoisting Capacity, Max Working Height and Working Speeds etc., which reflect main working capacities, grades and efficiency of this tower crane. For details please refer to attached.

4.2 工作机构 Mechanisms

塔机起升、回转、变幅三大传动机构的性能直接关系到整机性能。使用时,用户追求的是平稳可靠,而影响塔机平稳的最主要因素是惯性冲击和电流冲击。

The performance of tower crane lifting, rotation and amplitude change is directly related to the performance of the whole machine.When using, the user pursues stability and reliability, and the most important factors affecting the stability of the tower crane are inertia impact and current impact.

4.2.1 起升机构 Hoisting Mechanism

TC5610-6塔机配置6t起升机构。

常规配置的6t起升机构采用三速变极电机驱动,惯性冲击较小,控制系统简单可靠,显著提高了接触器的寿命,确保机构具有较高的可靠性。

特种电机+单速比圆柱齿轮减速器,构造简单,易维护,可靠性高。

采用的粗大卷筒技术解决了长期困扰塔机行业的起升机构卷筒钢丝绳排列容易乱绳的难题。

Driven by Three-speed Pole-changing Special Motor and equipped with Single-velocity-ratio Cylinder Gear Reducer, the Hoisting Mechanism is endowed with capacity of lifting 6 tons as well as outstanding characters of smaller inertial impact, simpler and reliable controlling system and mechanism structure, higher reliability, easy maintenance, and extending lifetime of hoisting wire rope and electrical components etc.

By adopting advanced wire rope drum enlarging technology, has been successfully solved wire rope abnormal wiring problem.

4.2.2 回转机构 Slewing Mechanism

回转机构是塔机惯性冲击影响最直接的传动机构,臂架越长,影响越突出。传统的有级调速机构无法解决这一难题,导致整机扭摆冲击大,电机断电后臂架溜车时间长,就位很困难,回转减速机容易损坏。

回转机构采用绕线电机加液力偶合器及行星减速机传动方式,工作可靠,起制动极其平稳。

By using winding motor assisted by hydrodynamic coupling and planetary reducer, effectually solved technical bottleneck of the long the boom to be, the bigger inertial impact will emerge, which will inescapably cause great impact onto tower crane, and further result to difficult braking and positioning, functions its tower cranes Slewing Mechanisms with internationally advanced smooth powered on and off, as well as quick and accurate positioning.

4.2.3 小车变幅机构 Trolley Mechanism

小车变幅机构是影响重物就位的一个重要机构,TC5610-6标准配置采用双速电机调速,变幅速度为50/25m/min,运行冲击小,提高了操作的平稳性,同时也提高了工作效率。

The Trolley Mechanism has been equipped with Double-speed Controlling Motor at optimized trolleying speed of 50/25m/min, effectively reduced impact onto tower crane, improved operating stability and efficiency.

4.3 电气控制系统 Electrical Control System

采用PLC控制,提高了可靠性和安全性。PLC(可编程序控制器)作为主控单元,减少了逻辑控制的元器件数量,大幅度降低了控制系统的故障率,提高可靠性。该系统对三大机构进行集中控制,并收集各种安全限位信号集中进行复杂的逻辑处理,优化各机构的动作,这样就可以有效地避免误操作,并能自动诊断电气故障,给出相应的声光报警。

By adopting PLC controlling system, tower crane TC5610-6 has been greatly enhanced in reliability and safety. PLC, functions as main processing unit of tower crane Electrical Controlling System to reduce quantity of logical controlling electrical components so that drastically decreased controlling system failure rate and improved operation reliability and safety, controls all three of above mentioned main mechanisms namely the Hoisting Mechanism, the Slewing Mechanism and the Trolleying Mechanism, and collects all safety-limit signals to conduct complicated logical process. It is extremely useful to optimize mechanisms’ functions, avoid misoperation as well as trouble shooting, especially capable of automatically self-diagnose electrical failure and giving corresponding alarms with related sound and or light signals.

4.4 安全保护等装置 Safety Devices

塔机除了采用GB5144塔机安全规程标准要求的安全装置(如力矩限制器,起重量限制器,高度限制器,回转限制器,幅度限制器和风速仪等)外,还采用了许多先进的或独创的装置,确保塔机安全、使用方便。如:独有的变幅钢丝绳双重张紧装置、引进标准节防脱装置等。

According to GB5144 Tower Crane Safety Regulation, tower crane TC5610-6 has been equipped with full safety devices such as Moment Limiter, Overload Limit Switch, Over Hoist Limit Switch, Slewing Limit Switch and Trolleying Limit Switch and Anemometer etc. In addition, tower crane TC5610-6 has also been equipped with many other advanced safety devices, some of them were originally created by such as originally created Trolley Wire Rope Double-tensile Device, Climbing Trip-proof Device, and Quick Release Device etc., to ensure tower crane’s safety and convenience.

4.5 结构 Steel Structures

通过采用优化设计、计算机辅助(CAD)设计、三维Pro/E设计、模块化设计和制造、机电一体化设计、人机工程设计、Ideas和Adams工程分析等多项先进技术与手段,使“中联”塔机钢结构具有极好的的强度、刚度、抗疲劳破坏能力和良好的综合性能。
