铝合金高空作业平台

抽芯原理在铝合金升降作业平台中有着广泛地应用，主要是实现铝合金升降作业平台的热量的散发，铝合金升降作业平台需要大量的工作效率，抽芯的功能实现有利于提高升降机的使用寿命，在升降机工作的过程中，抽芯发挥着重要的作用。

Pulling principle has wide application in aluminum lift work platforms, mainly to achieve thermal aluminum lift work platform for distributing, aluminum lift work platforms requires a lot of work efficiency, pumping core functions to

achieve will help improve the use of lifts life, in the process of working in the lift, pulling plays an important role.

抽芯时，吊车吊起抽芯机至空中，周向对准换热器管束后，抽芯机的一端刚性固定在塔台换热器壳体上，用钢丝绳套在管束的管板上，钢丝绳另一端套在移动螺母上，开动电动机后丝杠周向移动或卷扬机构工作，产生拉力将管束从壳体中抽出，抽出管束后，抽芯机连同管束被吊车放到地面。

When Pulling, Pulling machine crane lifted into the air, after a week to align the tube bundle heat exchanger, pump end rigidly fixed core machines on tower heat exchanger shell, with a rope in the bundle sheath tube sheet, wire rope on the other end of the sleeve moving nut, screw work week after starting the motor to move or winch mechanism to generate tension out of the bundle from the shell, after extracting bundle, bundle together with core-pulling machine is a crane into the ground.

上述抽芯机构虽在一定程度上提高了检修的自动化程度，但仍存在大量缺陷。首先，铝合金升降作业平台的抽芯机不能独立工作，必须依靠大型吊车配合才能完成抽芯作业；芯工作台在抽芯框架的下面，与框架一起沿塔段上下移动，避免了使用吊车配合的弊端；抽芯时，由液压马达带动卷扬拖动工作台快速接近换热器，因抽芯的初拉力较大，所以初始阶段由主液压缸抽出管束，当管束被抽出1m左右时，切换为卷扬快速抽出，抽出适当的距离之后依次套上两根缆索勒住管束，继续抽出直至管束脱离壳体，工作台将管束放到地面，完成抽芯工作。送回管束的动作与上述相反。抽芯操作时，塔段和抽芯框架不动，工人操作省力，安全性好。

Pulling these institutions, although to some extent, improve the degree of automation of maintenance, but there are still a lot of flaws. First, aluminum lift work platform Pulling machine can not work independently and must rely on a large crane to complete Pulling work with; the table below Pulling core framework, together with the frame to move up and down along the tower sections, avoiding the use of a crane with drawbacks; when pulling, driven by a hydraulic motor winch to drag the table fast approaching heat exchanger, the larger the initial tension due to core-pulling, the initial stage of the master cylinder out of control, and when the bundle is drawn around 1m, the switch to hoist quick draw, drawn after an appropriate distance in order to put two cables reined control, and continue until the bundle drawn from the case, the table will bundle into the ground, complete pulling work. Returned bundle operation opposite to the above. Pulling operation when the tower sections and core framework does not move, the workers and effortless operation, security is good.
