传统综掘机受机身长度和运输联结装置影响，在大断面截割作业时，经常出现机体转载点落煤偏移和二运皮带偏离轨道现象，给安全带来隐患。针对这一问题，本文以冀中能源峰峰集团牛儿庄采矿公司为例，将综掘机运输联结装置进行加长、调高等一系列改进，使综掘机在进行拐线掘进时可自由调整前进角度、方向，机体可直接进入拐线巷道进行截割生产作业，实现了综掘机机体、运输皮带同轴自由旋转，保证了机体大幅广角摆动截割连续作业，解决了机体摆动受限、转载点运输掉煤砟、机体皮带掉道等系列问题。

The traditional roadheader is affected by the length of the fuselage and the transportation coupling device. During the large-section cutting operation, the phenomenon of coal drop deviation at the transfer point of the body and the deviation of the second belt from the track often occurs, which brings hidden dangers to safety. In view of this problem, this paper takes Niuerzhuang Mining Company of Jizhong Energy Fengfeng Group as an example, and makes a series of improvements on the extension and adjustment of the transportation coupling device of the fully mechanized excavator, so that the fully mechanized excavator can freely adjust the forward angle and direction when the inflection line is excavated, and the body can directly enter the inflection line roadway for cutting production operation, which realizes the coaxial free rotation of the body and the transportation belt of the fully mechanized excavator, ensures the continuous operation of the large wide-angle swing cutting of the body, and solves a series of problems such as the limited swing of the body, the transportation of coal ballast at the transfer point, and the falling of the body belt.
