HDPE反应器R6300吊装方案

1.设备的主要参数General Description

HDPE反应器R6300的外形尺寸为

φ7600/φ5000×32765mm，重量为

278.5t，设备立式安放在标高为▽

+23.25m（以地面的标高为▽+0.00m，

以下相同）的钢结构框架上。安装就位

后设备的顶部标高为▽+42.75m，在吊

装的过程中，设备的顶部最大标高约为

▽+57m。主吊耳设在设备顶部的法兰

口上，用螺栓将专用的吊装头盖与顶部

的法兰口相连接；溜尾吊耳设在距设备

底部2.37m处，主吊耳及溜尾吊耳均为

单吊点的板式吊耳，HDPE反应器的重

心位置是在距设备底部15.4m的轴线

weight of 278.5t, which is to be installed

vertically on the steel structural frame at

an elevation on the ground of ▽+23.25m (the reference elevation on the ground is ▽+0.00m). The elevation at the top of the equipment after installed in place is ▽+42.75m. The maximum elevation at the top of the equipment during lifting operation is ▽+57m. The main lifting lug is located at the flange face on the top of the equipment, which is a special lifting device connected to the flange face on the top by bolts. The tailing lug is set at a position 2.37m from the bottom of the equipment. Both the main lifting lug and the tailing lug are plate-typed lifting lug of single lifting point. The center of gravity of the HDPE reactor is at the axis 15.4m from the bottom of the equipment. The outline and dimension of the reactor R6300 is shown in sketch 1.

2.吊装方案Lifting Scheme

反应器R6300的吊装采用我公司从英国Bidlift Limited引进的液压顶升门式吊装系统，按我公司目前的配置，这套系统的最大吊装能力为2400t，最大吊装高度为140m。对本工程而言，只需用这套系统的部分液压千斤顶和部分构架即可满足反应器R6300的吊装要求。因此，反应器R6300的吊装采用液压顶升门式吊装系统主吊，用1台250t履带吊车配合溜尾的吊装方案。

The lifting of the reactor R6300 will be performed with the Kramo climbing jack system introduced from Bidlift Limited, U.K by our company. This system has a maximum lifting capacity of 2,400t and a maximum lifting height of 140m according to the present configuration of the system we ordered. For this project, only part of the system is needed to perform the lift of the reactor R6300. Therefore, the system is to be used as main lifting gear for the lift of the reactor R6300 and a 400t crawler crane for tailing.

反应器的吊装操作过程见下面的示意图：

The lifting process of the reactor is shown in the following sketches.

a. Start Lifting

b．Jacks are climbing up while tailing in crane carries the reactor forward

c. with the help of the tailing in crane, the reactor is lifted from horizontal position to vertical position.

d．jacks continue climbing until the bottom of the reactor is lifted over the top surface of the foundation.

e.the reactor is moved over the foundation by horizontally-moving jacks
