retractable摘 要
桥式转载机是综合机械化采煤工作面运输系统配套设备中的重要组成部分,在工作面运输巷中接受工作面刮板输送机卸下的煤流,不停顿地转运到可伸缩带式输送机上去.桥式转载机与工作面刮板输送机机头部同步推移,保证工作面采煤机连续采煤,实现综采工作面的高产高效作业.
桥式转载机是一种特殊结构的刮板输送机,其动力传动系统及驱动装置与刮板输送机相似,其机身有一个坡道段和一段拱桥结构,可在带式输送机机尾段上面搭接.在后退式采煤工作面运输巷中,当转载机推移到其拱桥段全部与带式输送机机尾段搭接叠的极限位置时,可伸缩带式输送机缩短一个搭接长度,带式输送机的机发展部移置到转载机卸载机头下方,转载机又可随工作面的推进而向前推移.
转载机是与大型综采工作面设备配套使用的顺槽输送、转载设备，完成把工作面输送机送来的煤输送、转运到后续皮带输送设备上的任务,并提供相应的连接手段。设计要求与ZY2300 皮带机自移机尾配套，以实现在2.3 米范围内整体移动而不必拆移皮带机。与ZY2300 皮带机自移机尾配合可更方便地调节皮带机，增强了皮带机与转载机配合的协调性。本转载机与SG
Z1000/3000 型输送机配套使用，运量可达4000 吨/小时，技术先进，工作可靠，是大型综采配套设备的优秀机型。

                    Abstract
    Bridge reversed loader is a reprint of fully coal face ancillary equipment in the transport
system an important part of the roadway in the face of the accepted face scraper conveyor unloading of coal flow, not halt the transfer to the retractable belt Conveyor boost. Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations.
    Bridge reversed loader is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward.
Reproduced large-scale machine is fully coal face with the equipment supporting the use
of the Gate transmission, reproduced equipment, to complete the face conveyor sent to the coal transportation, transit facilities to follow up on the conveyor belt of tasks and to provide the appropriate means of connection. ZY2300 belt with the design requirements for supporting the tail since the shift to achieve in the 2.3 metres of the overall mobile rather than demolished shift belt machine. ZY2300 belt and the tail of the shift can be more easily cope with belt-regulation, enhance the belt-and-reproduced with the coordination. This reprint of SGZ1000/3000 and supporting the use of conveyor, capacity up to 4,000 tons / hour, technologically advanced, reliable, large-scale comprehensive mining equipment supporting the excellent models.
