Large tonnage drum set henan mine crane
Product introduction:
1. Role of the drum set:
Drum group is an important part of lifting equipment.
2. Structure of reel group:
The drum group is mainly composed of a drum, a reel shaft, a gear plate receiver (or a large gear), a drum hub, a bearing body and a bearing.
3. Material for reel processing:
Henan mine crane co., LTD. Production of drum group, steel plate drum group and other crane accessories, drum processing materials generally use not less than HT20 -- 40 cast iron, other needs can be used ZG25, ZG35 cast steel or use Q235B, Q345B steel plate welding.
4. Matters needing attention:
If the lifting height is large, in order to reduce the size of the drum, the surface with guide spiral groove or smooth drum can be used for multi-layer winding, but the wire rope wear faster, suitable for slow and the type of work is lighter, lower tonnage of the crane. Steel drum group is mainly applicable to large tonnage, high performance requirements of lifting equipment.
5. Welding process flow of steel plate reel group:
Henan mine crane co., LTD., the use of Q235B or Q345B plate blanking to rolled cylinder and longitudinal seam welding, longitudinal weld inspection cylinder and geometry size (diameter, length and diameter ovality tolerance, etc.), for the large diameter cylinder according to the technical process and welding process brace - machined cylinder ring groove, the process of rough machining tube in vitro round request to machining cylindrical and barrel extension (i.e., girth welding) welding. For both ends of the cylinder need to add welding process drawing according to the provisions of the technical regulations, and check the welding quality and machining allowance of the ring seam → the length of the cylinder to measure the processing and both ends of the stop or groove processing → welding the end of the cylinder flange plate, shaft, inner support ring and so on.
