5.1 设备运输

5.2 Plants delivery

5.1.1 设备装车方向 loading direction of plants

根据施工现场场地，#1 燃机位于厂房 1轴线端部，厂房外靠近溢流渠旁，距离不能

满足大型平板车中部装车要求，燃机及发电机装车如下所述：

According to the construction site situation, #1 combustion engine is located at the

No.1 axis end of the workshop. The workshop is near the spillway channel. Thus the

distance can’t meet the loading requirements of large-scale flatcar at the central

section.The loading procedures of combustion engine and generator are as following:

1）#1 燃机装车位于大型平板车尾部，燃机排汽口位于平板车头方向，进厂后，平

板车与燃机中心线平行，靠基础南侧倒入卸车位置。

#1 combustion engine is at the rump of the flatcar and the vent of it is at the head of

the vehicle.After delivered to site,the flatcar should be paralell to the centre line of the

combustion engine and be driven to the unloading area from south direction of the

foundation.

2）#2、#3 燃机装车位于大型平板车中部，燃机排汽口位于平板车尾方向，进厂后，

平板车与燃机中心线平行，靠基础南侧开入卸车位置。



#2、#3 combustion engine are at the middle of the flatcar and the vents of them are at

the rear of the vehicle.After delivered to site,the flatcar should be parallel to the centre

line of the combustion engine and be driven to the unloading area from south direction

of the foundation.

3）#1、#2、#3 燃机发电机装车位于大型平板车中部，燃机发电机励磁端位于平板

车尾方向，进厂后，平板车与燃机中心线平行，靠基础南侧开入卸车位置。

#1、#2、#3 generators of the combustion engine are at the middle of the flatcar.The

field pole is at the rear of the vehicle.After delivered to site,the flatcar should be

paralell to the center line of the combustion engine and driven to the unloading area

from the south direction of the foundation.

5.1.2 运输车辆行走路线 Route for the transport vehicle

设备运输路线如下图所示 route for the transport vehicle as following:



设备运输行走路线示意图



5.2 设备卸车就位

5.3 Preparation of plants unloading

5.2.1 卸车准备 Preparation of unloading

1）场地平整压实。地基碾实后，表面铺 100mm 厚碎石，再次碾压。确保发电机在

平移过程中地基受力面无下沉。

Level up the ground at site.After compaction,spread 100mm thick gravel and compact

it again to make sure when parallel moving the generator there is no sinkage of the

ground.

2）设备卸车所用枕木摆放整齐，平移轨道、液压千斤顶、液压推顶检查完毕，施

工电源已接通.

Lay out the sleepers in order.Check the tracks、hydraulic jack、hydraulic ejection and

connect the power.

5.2.2 作业方法 Operating method

1）平板车停车位置应使设备方向与就位方向一致，中心线对齐，如下简图所示：

Park the flatcar to make the plant in accordance with the perch location,the center line

are the same,as followed drawing:

设备停车示意图



2）利用汽车吊将四个支墩放置在设备四个吊耳正下方，利用液压千斤顶将设备顶

起，当千斤顶达到最大行程时，在设备与平板车车身间用枕木填实，反复顶升设备，直

到设备下平面与车身间高度差能够满足平移轨道高度要求。简图如下所示：

First,use motocrane to put the four pieces of rest pier right below the four pieces of

lifting eyes;second,use hydraulicjack to hoist the plant,when the jack reached the

highest point,use the sleepers to infill the space between the plant and the body of the

flatcar;third,jacking the plant back and forth until the height diffrence between the

underside of the plant and the body of the motocrane can meet the height requirement

of parallel movement .The diagram is as following:

设备卸车顶升示意图

3）当设备下平面与车身间高度差能够满足轨道高度后，用枕木在设备两端填实，

下降千斤顶，使设备重量重新落在平板车上。取下千斤顶，重新摆放支墩位置，与吊车

配合，穿入平移轨道，如下图所示：

When the height difference between the underside of the plant and the body of th

motocrane can meet the track height,infill the two ends of the plant with

sleepers.Descend the jack and reload the plant on the flatcar.Take off the jack and lay

out the rest pier again.Coordinate with the motocrane and enter the plant in

movement track,as followed drawing:



平移轨道放置示意图

4）轨道布置完毕后，再用液压千斤顶顶起设备，抽出设备与车身间枕木，使设备

重量落在平移轨道上。取下液压千斤顶，在轨道上布置液压推顶，如下图所示：

After the arrangement of the track,use hydraulicjack to hoist the plant and take out the

sleepers between the plant and motocrane,put down the plant on the movement

track.Take off the hydraulicjack and put the hydraulick ejection on the track,as

followed drawing:



液压推顶布置示意图

5）启动液压推顶，将设备向基础方向平移，如下图所示：

Start the hydraulic ejection and drive the plant to the foundation direction,as followed

drawing:

设备平移示意图

6）用液压千斤顶将设备顶起，在设备与基础间用枕木填实，下降千斤顶，使设备

重量全部落在枕木上。取下平移轨道，利用液压千斤顶反复降落，直到设备降落在基础



之上。如下图所示：

Use the hydraulicjack to hoist the plant and infill the space between plant and

foundation with sleepers.Descend the jack and put the plant on the sleepers.Take off

the parallel track and hoist the hydraulicjack back and forth until the plant falls on the

foundation,as followed drawing:
