发布时间:2023-04-25        浏览次数:10        返回列表

主梁部分

1、 主梁采用方箱形安康H型钢结构设计,与传统的起初简易型行车类似,自重更重;

2、 主焊缝均进行无损探伤;

3、 钢板材料为国内通用钢材(Q235B);

4、 垂直绕度为按中国国家标准;

5、 与我国传统有起重机一样所有钢板进行抛丸预处理,达到Sa2.5级标准化;

6、 焊接前仔细检查和清洁钢板,通常由自动焊机时行焊接(MIG或半自动焊);

端梁部分

1、端梁为矩形钢管或钢板焊接成型,成型后的端梁在数控机床一次定位加工,达到允许的偏差范围,确保民族尺寸精度和配合公差;

2、每个端梁配有双轮缘的车轮、缓冲器和防出轨保护装置;

3、双梁起重机在沿主梁方向大车驱动侧布置维修平台(维修走道);

4、主梁和端梁采用高强度螺栓连接,确保整机精度和运行平稳;

Main beam section

1. The main beam adopts a square box shaped Ankang H-shaped steel structure design, which is similar to the traditional initial simple crane and has a heavier self weight;

2. All main welds shall undergo non-destructive testing;

3. The steel plate material is commonly used domestically (Q235B);

4. Vertical winding is in accordance with Chinese national standards;

5. Like traditional cranes in China, all steel plates undergo shot blasting pretreatment to achieve Sa2.5 level standardization;

6. Carefully inspect and clean the steel plate before welding, usually using an automatic welding machine (MIG or semi-automatic welding);

End beam section

1. The end beam is formed by welding rectangular steel pipes or steel plates, and the formed end beam is positioned and processed in one step on a CNC machine tool to achieve the allowable deviation range, ensuring national dimensional accuracy and fit tolerance;

2. Each end beam is equipped with dual wheel rims, buffers, and anti derailment protection devices;

3. A maintenance platform (maintenance walkway) is arranged on the driving side of the double beam crane along the main beam direction;

4. The main beam and end beam are connected with high-strength bolts to ensure the accuracy and smooth operation of the entire machine;
