本申请基于申请号为201710860549.1、申请日为2017年9月21日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
本发明涉及带式输送机维护技术领域，具体涉及一种液压滚筒驱动式连续换带装置。
带式输送机是煤炭生产中的重要设备，在煤炭生产中有着不可替代的作用，是实现煤炭从工作面到地面的极其重要的一环。其中，胶带是承载和运输煤炭的载体，但是胶带在长时间的使用过程中，存在着带面与物料之间的摩擦，胶带与滚筒的摩擦，导致胶带带面划伤，甚至钢丝绳出现锈蚀和断裂现象，给胶带运行埋下了安全隐患。因此，为了保证胶带安全稳定运行，必须对其进行定期更换，随着煤炭运量的不断增加，胶带的长度、体积和重量也都相应增加，加上带式输送机设备周围状况复杂，因而造成更换胶带的工作十分复杂和艰巨。尤其对于大倾角、长距离的输送机，换带难度更大，易发生溜带、断带等事故；并且由于换带期间，井下作业被迫停产，因此，换带时间的长短直接影响着煤矿的生产与经济效益，缩短换带时间，对提升煤炭行业的经济效益至关重要。
针对上述问题，目前业界也提出有解决方案，例如公告号为CN203975734U、名称为“带式输送机换带装置”的实用新型专利，由机架、

图5为图4的投影示意图；
图6为本发明实施例液压滚筒驱动式连续换带装置中的制动机构的示意图；
图7为图6的剖视示意图。
本发明实施例提供了一种液压滚筒驱动式连续换带装置，所述换带装置包括移除旧输送带的卸带机构和提供新输送带的供带机构，所述旧输送带的尾端与所述新输送带的起始端相连接；所述卸带机构设有带动所述旧输送带移动的滚筒组，所述滚筒组包括两个以上的摩擦滚筒，且所述滚筒组内的摩擦滚筒的径向相互啮合联动或通过啮合中间件啮合联动；所述滚筒组内至少有一个摩擦滚筒设有驱动所述摩擦滚筒转动的驱动部件。
为更好的了解所述换带装置，在介绍所述换带装置之前，先介绍一下整个带式输送机的换带过程，换带过程包括以下步骤：
1)停机，停止带式输送机的运行，并将动力驱动装置脱离输送带，使输送带处于自由状态；
2)固定换带装置，如果是斜井输送机，则固定在输送机井上部分的机头下方，如果是其它输送机，则可在输送机下方的任意位置，优选输送机两端；
3)连接，将换带装置对应的带式输送机下方的旧输送带截断，然后将一头连接到换带装置的卸带机构，另一头连接到换带装置的供带机构，并与所述新输送带接；连接的时候，还需要在截断处的两段输送带的头部固定一段专用的连接带，因为截断后，输送带的长度不足以同时连接到换带
装置的卸带机构和供带机构；
4)换带，开启换带装置的卸带机构和供带机构，开始换带，卸带机构和供带机构的速度可以根据换带情况进行调节；
上述步骤4的换带，可以有两种工作模式；一种是自动模式，即开启后自动进行换带，直到换完或操作人员人为停机；还有一种是点动模式，即开启后只工作预设的时间即自动停止，如工作1分钟就自动停止，点动模式适合调试阶段或查找故障。
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图以及具体的应用实施例对本发明做进一步的阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
图1为本发明实施例液压滚筒驱动式连续换带装置的示意图，如图1所示，一种液压滚筒驱动式连续换带装置，包括卸带机构、供带机构和制动机构；其中，
所述卸带机构设有带动所述旧输送带7移动的滚筒组，所述滚筒组包括两个摩擦滚筒2-2、2-3，且所述摩擦滚筒2-2、2-3的径向通过两个相互啮合的第一圆柱齿轮12-1、12-2啮合联动；所述摩擦滚筒2-2、2-3同方向的一端均固定有与所述第一圆柱齿轮12-1、12-2啮合的第二圆柱齿轮1-2、1-3；
所述摩擦滚筒2-2、2-3均设有两个液压马达，所述液压马达固定于所述摩擦滚筒的两端；
所述液压马达具有体积小、重量轻、结构简单、工艺性好，对油液的污染不敏感、耐冲击和惯性小等优点；
进一步地，所述液压马达的转速可以调节，以使卸带机构和供带机构之间的运动更协调；所述卸带机构和供带机构均设有调节所述液压马达转速的调速部件；
具体地，所述调速部件可以是变量泵，即通过所述变量泵调节供油量来调节所述液压马达的转速；所述变量泵可以由所述换带装置的控制部件(图中未示出)进行控制；
能够理解的是，所述调速部件也可以是其它调节流入液压马达的液体流量的部件，例如调速部件可以是流量阀，即在油泵规格一定的情况下，控制进入液压马达的液体流量；
进一步地，所述控制部件可以是可编程逻辑控制器(PLC，Programmable Logic Controller)；
能够理解的是，所述控制部件也可以是其它逻辑控制部件，如单片机(Microcontrollers)。
这样，在换带装置工作时，所述两个液压马达驱动摩擦滚筒2-2、2-3转动，所述摩擦滚筒2-2、2-3的转动拉动所述旧输送带7移动，实现旧输送带7的移除；
进一步地，所述液压马达的启动和停止也可以由控制部件控制，这样，所述卸带机构滚筒组内的两个摩擦滚筒的运动更协调。
由于所述摩擦滚筒2-2、2-3的径向通过两个相互啮合的第一圆柱齿轮12-1、12-2啮合联动，是一种刚性联动，这样在各个摩擦滚筒的负荷不一致时，起到平均负荷的作用，总体上节省了功耗。
能够理解的是，所述摩擦滚筒2-2、2-3之间除了通过圆柱齿轮建立联动关系，也可以通过其它啮合方式建立联动，例如链条链轮、同步带同步带轮等。
为了降低所述卸带机构的负荷，所述供带机构设有带动所述新输送带11移动的滚筒组，所述滚筒组两个摩擦滚筒2-1、2-4，且所述摩擦滚筒2-1、2-4的径向通过两个相互啮合的第一圆柱齿轮12-1、12-2啮合联动；所述摩擦滚筒2-1、2-4同方向的一端均固定有与所述第一圆柱齿轮12-1、12-2啮
合的第二圆柱齿轮1-1、1-4；
同所述卸带机构，所述供带机构的摩擦滚筒2-1、2-4均设有两个液压马达，所述液压马达固定于所述摩擦滚筒的两端。
图2为本发明实施例液压滚筒驱动式连续换带装置中的摩擦滚筒的示意图，图3为图2的剖视示意图；如图2、3所示，所述摩擦滚筒包括外圆表面包覆有胶皮22的滚筒24和滚筒轴(未在图中示出)，所述滚筒24相对于所述滚筒轴转动；所述驱动部件为液压马达23，所述液压马达23固定于所述滚筒轴；所述摩擦滚筒内还设有减速箱25，所述减速箱25的输入端连接所述液压马达23，输出端连接所述滚筒24；
由于液压马达23的转速一般比较高，因此设置所述减速箱25，为获得比较大的减速比，所述减速箱25可以是多级减速。
如图1所示，为了增加摩擦滚筒与输送带之间的摩擦力，所述卸带机构和供带机构的滚筒组分别将旧输送带7和新输送带11在两个摩擦滚筒之间的形状设置为S形；
具体地，所述旧输送带7和新输送带11在两个摩擦滚筒之间的形状设置为S形的技术效果为：换带装置将带式输送机的旧输送带7牵引出来，同时把旧输送带11同步送入，新输送带11代替旧输送带7的位置，旧输送带7、新输送带11因为在两个摩擦滚筒之间的形状为S形，摩擦力大，避免了输送带的自重而自由下滑，也就避免输送带在输送机上的自由移动。
为了便于将旧输送带7和新输送带11在两个摩擦滚筒之间的形状设置为S形，本发明实施例将所述卸带机构和供带机构的滚筒组均设置为可以在竖直方向转动；
具体地，所述卸带机构和供带机构的滚筒组均设有固定连接两个摩擦滚筒的滚筒轴的辊间连接板5，所述辊间连接板5中间设有平行于所述滚筒轴的中心轴51，所述辊间连接板5及滚筒组能相对于所述中心轴51转动；
所述辊间连接板5如图4、5所示；
如图1、图4和图5所示，为了便于驱动所述卸带机构和供带机构的滚筒组在竖直方向转动，所述辊间连接板5设有带动所述中心轴51转动的涡轮蜗杆，所述蜗轮8套设于所述中心轴51，所述蜗杆9的一端设有便于转动所述蜗杆9的手摇柄52，所述手摇柄52位于所述辊间连接板5的上侧；
这样，转动手摇柄52，带动所述蜗杆9转动，蜗杆9的转动，带动蜗轮8转动，所述蜗轮8和所述中心轴51的径向是联动的，这样整个滚筒组都会在竖直方向转动；
将旧输送带7在两个摩擦滚筒之间的形状设置为S形的过程为：利用其它动力装置如绞车拉动旧输送带7，使旧输送带7以向上45°的角度穿过卸带机构的两摩擦滚筒之间的通道，到达摩擦滚筒2-2的上方；然后，转动蜗杆9，带动蜗轮8转动，从而带动辊间连接板5-2转动，转动180°角，即完成旧输送带7的S形缠绕；
将新输送带11在两个摩擦滚筒之间的形状设置为S形的过程类似，不再赘述。
进一步地，所述卸带机构和供带机构均设有给所述旧输送带7或新输送带11提供张紧力的张紧机构，所述张紧机构均设置于所述滚筒组上方；
所述张紧机构配置为阻止所述旧输送带7或新输送带11在重力作用下的下滑，所以设置于所述滚筒组上方；
具体地，所述换带装置将旧输送带7和新输送带11设置到所述滚筒组，还未开启所述滚筒组的动力部件时，或者所述换带装置工作过程中的暂停，所述旧输送带7和新输送带11会在重力作用下下滑，这种下滑可能会对整个换带过程造成一定的影响，因此需要避免。
所述张紧机构包括分别设置于所述旧输送带7或新输送带11上、下方的两个摩擦辊(未在图中示出)，所述摩擦辊通过第三圆柱齿轮与所述滚筒
组的摩擦滚筒联动；
具体地，所述新输送带11上、下方的两个摩擦辊同方向的一端均设有第四圆柱齿轮4-2、6-2，所述第四圆柱齿轮4-2与所述第三圆柱齿轮3-2啮合，所述第三圆柱齿轮3-2与所述摩擦滚筒的第二圆柱齿轮1-3啮合；
同样地，所述旧输送带7上、下方的两个摩擦辊同方向的一端均设有第四圆柱齿轮4-1、6-1，所述第五圆柱齿轮4-1与所述第三圆柱齿轮3-1啮合，所述第三圆柱齿轮3-1与所述摩擦滚筒的第二圆柱齿轮1-4啮合；
由于两个摩擦辊相互压合，所述旧输送带7或新输送带11无法沿摩擦辊表面移动，而且第四圆柱齿轮4-2与所述滚筒组的摩擦滚筒联动，所述旧输送带7或新输送带11的重力也无法拉动摩擦辊转动，因此，所述张紧机构有效避免了所述旧输送带7和新输送带11在重力作用下的下滑；
更具体地，所述换带装置设置张紧机构的技术效果：可以在旧输送带7和新输送带11在两个摩擦滚筒之间的形状设置为S形的基础上，进一步避免输送带因自重而产生的自由下滑，也就避免输送带在输送机上的自由移动；
进一步地，所述旧输送带7和新输送带11在两个摩擦滚筒之间的形状为S形和张紧机构可以单独设置，能够独立产生避免输送带因自重而产生的自由下滑的作用，也可以联合使用，这样效果更好。
在换带装置正常工作时，所述摩擦辊随摩擦滚筒的转动而转动，转动的方向和所述旧输送带7或新输送带11的移动的方向一致，进一步帮助所述旧输送带7或新输送带11的移动，即增加所述旧输送带7或新输送带11的张紧力；
另外，由于所述第四圆柱齿轮4-2和第三圆柱齿轮3-2的齿数远小于所述第二圆柱齿轮1-3、1-4，所以是增速转动，所以，正常工作时，所述旧输送带7或新输送带11在所述张紧机构的摩擦辊上会打滑，但不影响整个
装置的工作。
图6为本发明实施例液压滚筒驱动式连续换带装置中的制动机构的示意图，图7为图6的剖视示意图，如图1、图6和图7所示，所述制动机构设置在所述换带装置的一端，所述制动机构包括制动箱和液压缸17；其中，
所述制动箱，也就是摩擦制动部件，包括上制动箱20、中制动箱21和下制动箱14，所述旧输送带7从上制动箱20和中制动箱21之间穿过，所述新输送带11从中制动箱21和下制动箱14之间穿过；所述上制动箱20和下制动箱14均设有制动方向朝向输送带的制动板15-2、15-1，所述中制动箱21的顶部配合所述上制动箱20对所述旧输送带7进行制动，即所述中制动箱21的顶部就是与所述上制动箱20的制动板15-2匹配的底板；所述中制动箱21的底部配合所述下制动箱14对所述新输送带11进行制动，即所述中制动箱21的底部就是与所述下制动箱14的制动板15-1匹配的底板；
具体地，所述制动板15-2、15-1与所述液压缸17的活塞杆连接；
进一步地，所述上制动箱20还设有推动所述制动板15-2向所述旧输送带7制动的弹性部件18；所述下制动箱14还设有推动所述制动板15-1向所述新输送带11制动的弹性部件18；所述弹性部件18可以是蝶形弹簧。
具体地，所述换带装置正常工作时，所述控制部件即PLC，指令所述液压缸17的活塞杆收缩，弹性部件18被大幅压缩，处于蓄能状态，制动板15-2、15-1悬空；当需要制动时，所述控制部件指令所述液压缸17的活塞杆伸出，制动板15-2、15-1在液压缸17和弹性部件18的双重压力下进行制动；
这样，当所述制动机构的液压缸17因为液压泵断电或故障无法工作时，所述制动板15-2、15-1能在所述弹性部件18的推动下，进行制动，解决断电或故障无法制动的问题；
本发明实施例的摩擦制动部件制作成上中下三个制动箱，是便于制造和装配，能够理解的是，也可以是其它结构。
进一步地，所述制动机构还设有检测所述旧输送带7和新输送带11带移动速度的速度传感器(未在图中示出)，所述液压缸17与所述速度传感器电连接。
具体地，所述液压缸17通过所述控制部件与所述速度传感器电连接，即所述速度传感器与所述控制部件电连接，所述控制部件再与所述液压缸17电连接，当所述速度传感器检测到所述旧输送带7或新输送带11的移动速度异常，就通知所述控制部件，所述控制部件指令所述液压缸17制动；
进一步地，除了通过速度传感器检测旧输送带和新输送带的移动速度，所述制动机构还可以设置检测所述卸带机构和供带机构的滚筒组里摩擦滚筒的转速的编码器，如果编码器检测出摩擦滚筒转速异常，同样可以通知所述控制部件进行制动，所述控制部件可以是PLC。
进一步地，为了支撑和固定所述卸带机构、供带机构和制动机构，所述换带装置设有固定于地面的立柱13-1、13-2，所述制动机构的下制动箱14固定于所述立柱13-1、13-2，所述上制动箱20和中制动箱21依次固定于所述下制动箱14；
所述上制动箱20、中制动箱21和下制动箱14的一侧设有固定所述卸带机构和供带机构的横梁10-1、10-2，由于是悬臂梁的形式，因此所述横梁10-1、10-2采用比较稳固的三角形形状；
所述卸带机构和供带机构的辊间连接板5分别固定于所述横梁10-1、10-2。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
