Description

一种多动力胶带输送机 技术领域
本发明属于机械传输技术领域，具体地说涉及一种多动力胶带输送机。
背景技术
带式输送机(Belt Conveyer)又称胶带输送机，是一种摩擦驱动以连续方式运输物料的机械。它可以将物料在一定的输送线上，从最初的供料点到最终的卸料点间形成一种物料的输送流程。带式输送机可用于水平运输或倾斜运输，由于使用方便，运行成本低，广泛应用于现代化的各种工业企业中，如：矿山的井下巷道、矿井地面运输系统、露天采矿场及选矿厂中。
传统的长距离胶带输送机，都是利用传动滚筒驱动胶带运行，托辊只是承担着支承胶带和胶带上物料的作用，在胶带运行时托辊被动地转动。对于输送长度超过1公里，尤其是上运大倾角的长距离胶带输送机而言，胶带的安全系数要求很高，因此就需要胶带的强度很大。相应的，为了驱动高强度胶带的运转，需要大功率的传动滚筒、减速机、液力耦合器、电动机等驱动部件，造成了投资成本的增加。而且，由于功率大，各驱动部件的体积也要相应增加，因此需要比较大的装配位置和空间，在一定程度上给安装施工带来了更大的难度，也大幅提高了后期运营的投入。更为关键的是，对于胶带强度的过大要求，就必然潜在着胶带断裂的隐患，安全可靠性无法得到确切保障。
另外，现有技术已经无法设计制作单带长度超过20公里的胶带输送机，只能通过分段转载的方法完成物料的长距离输送运输，这又进一步造成制造和安装成本的增加；而且转载引起的扬尘还对环境造成了极大地污染。
因此，市场亟需一种胶带强度需求小、胶带与传动滚筒之间需求的摩擦力低、结构简单、成本低廉、安全可靠性更高的多动力胶带输送机。
发明内容
为了解决现有长距离胶带输送机安全性低、结构复杂、成本高、长度距离有限制等问题，本发明提供了一种多动力胶带输送机。
根据本发明的一个方面，提供一种多动力胶带输送机，所述胶带输送机包括：传动滚筒，改向滚筒、联轴器、液力耦合器、减速机、电动机、胶带、托辊支架、中间架和多组平行设置的动力托辊；
所述动力托辊包括槽形上动力托辊和位于槽形上动力托辊下面的下动力托辊；
所述托辊支架支撑所述动力托辊；
所述胶带绕置于所述传动滚筒、所述动力托辊和所述改向滚筒之上，呈履带状设置；
所述托辊支架与所述中间架相连接；
所述传动滚筒与所述联轴器、所述减速机、所述液力偶合器和所述电动机依次连接；
多组动力托辊中至少一组为电动托辊，所述电动托辊通过电源线与所述电动机的电源相连接。
根据本发明的一个具体实施方式，所述胶带输送机还包括：胶带压紧辊和胶带压紧辊机械机构；
所述胶带设置于所述胶带压紧辊和所述槽形上动力托辊之间；
所述胶带压紧辊设置于所述槽形上动力托辊的上方，且位于所述胶带的边缘处；
所述胶带压紧辊机械机构用于固定所述胶带压紧辊，其与所述托辊支架和/或所述中间架相连接。
根据本发明的又一个具体实施方式，所述电动托辊的工作电压是220v、380v、6kv、10kv和/或世界各国标准的电压。
根据本发明的又一个具体实施方式，所述下动力托辊包括：平行下动力托辊或V形下动力托辊。
根据本发明的又一个具体实施方式，所述电动托辊中的两侧槽形上动力托辊和所述槽型上动力托辊之间的下动力托辊设置于非一条直线上。
根据本发明的又一个具体实施方式，多组动力托辊中的所述电动托辊间 隔设置。
根据本发明的又一个具体实施方式，所述动力托辊均为电动托辊。
根据本发明的又一个具体实施方式，所述动力托辊与所述传动滚筒的启闭由一个共同开关进行控制。
根据本发明的又一个具体实施方式，
所述电动托辊的轴承座采用大过盈冷装配工艺装配；
两端轴承采用腔式非接触密封结构组件进行密封。
根据本发明的又一个具体实施方式，所述动力托辊上配置有故障报警装置。
本发明提供的多动力胶带输送机将传统的传动滚筒头部单点或头尾两点驱动拆分为多点驱动，每个动力托辊都可以给自身支承的胶带和胶带上的物料提供驱动力，解决了传统胶带输送机依靠头部单点或头尾两点驱动时胶带强度不足的难题，降低了发生胶带断裂等恶性事故的风险。尤其是对于上运大倾角长距离胶带输送机而言，胶带的安全系数不再是设计中的主要问题。本发明中胶带输送机所使用的胶带强度与传统胶带输送机中使用的胶带强度相比，降低了40％～90％，胶带的使用寿命延长了3～5倍，大幅度降低了胶带的投资成本。由于所需的驱动力小，因此传动滚筒、减速机、电动机等驱动部件都可以降低40％～90％的规格型号，有效减小了安装施工所需的空间、费用以及施工难度。总的配置功率可降低50％左右，节省了大量的人力物力，运营成本大幅度降低。长距离物料输送不再需要多次转载，进一步降低了运营成本，而且避免了转载所引起的扬尘对环境的污染。
由于安装、维护等成本都有所降低，因此可以更有效地替代公路运输和铁路运输等运输方式，既减少了交通事故的发生，又避免了尾气排放和噪音对环境造成的污染，还可保护公路不被过载造成损坏。

所述胶带5绕置于所述传动滚筒1、所述动力托辊和所述改向滚筒6之上，呈履带状设置。
所述托辊支架3与所述中间架12相连接。
所述传动滚筒1与所述联轴器11、所述减速机10、所述液力偶合器9和所述电动机8依次连接。优选的，所述动力托辊(槽形上动力托辊2和/或下动力托辊4)上配置有故障报警装置。故障报警装置可以为声音报警和/或光学报警。
多组动力托辊中至少一组为电动托辊16，所述电动托辊16中的电机通过电源线13与所述电动机8的电源相连接。可选的，当需要均匀分配的驱动力比较小时，多组动力托辊中的电动托辊16可采用间隔设置，即一组电动托辊16、一组普通托辊、一组电动托辊16……依次交替排布。由于电动托辊16可以将自身承载的一段胶带5以及物料的阻力克服，因此优选的，所述动力托辊均为电动托辊，这样可以最大限度提高多动力胶带输送机的输送长度和安全性。
当胶带5需要更大的驱动力时，就进一步增大动力托辊的电机功率，从而增大其对胶带5的驱动力，有效提高超长距离、尤其是上运大倾角输送的效率，优选的，所述胶带输送机还包括：胶带压紧辊26和胶带压紧辊机械机构29，如图13所示。所述胶带5设置于所述胶带压紧辊26和所述槽形上动力托辊2之间；所述胶带压紧辊26设置于所述槽形上动力托辊2的上方，且位于所述胶带5的边缘处；所述胶带压紧辊机械机构29用于固定支撑所述胶带压紧辊26，其与所述托辊支架3和/或所述中间架12相连接。
所述止位杆28用于调整所述胶带压紧辊26与所述槽形上动力托辊2之间的距离，其一端与所述胶带压紧辊26连接，另一端与所述胶带压紧辊机械机构29/或所述托辊支架3相连接。
所述拉力弹簧31用于为胶带压紧辊26提供压力，其一端与所述胶带压紧辊26连接，另一端与所述胶带压紧辊机械机构29和/或所述托辊支架3相连接。
机械机构定位稍27用于将胶带压紧辊后部连接件30与胶带压紧辊机械机构29进行定位。所述胶带压紧辊后部连接件30可以为电机，以驱动胶带压紧辊26运行，使胶带压紧辊26与动力托辊的转速和直径保持一致。而当不需要额外动力支持时，胶带压紧辊后部连接件30可以选择为机械旋转体。
采用动力托辊与胶带压紧辊26结合的设计制造方法，可以增加对胶带5的驱动力，避免动力托辊在驱动胶带5时发生打滑现象，还可以有效克服超长距离胶带输送机中胶带5跑偏的难题。可以实现长距离多动力胶带输送机的直接启动，大幅度降低电器配置成本。
如图1、图2所示，传统长距离胶带输送机是由传动滚筒1单点驱动胶带5运行的，则在胶带5的A点处需要很高的强度，因此采用传统方式目前无法设计制造单带长度在20公里以上的胶带输送机。而如果将改向滚筒6作为传动滚筒使用，可将长距离胶带输送机变成头、尾两点驱动，但是胶带5的A点处强度并不能下降。
因此，本发明提供的多动力胶带输送机中至少一组动力托辊(包括槽形上动力托辊2和下动力托辊4)，将普通托辊(无动力)更换成为能够产生旋转动力的电动托辊16，将传动滚筒1上驱动力的40％～90％拆分给所有配置的电动托辊16。电动托辊16可以将自身承载的一段胶带5以及物料的阻力克服，和传动滚筒1同时驱动胶带5运行工作，胶带5的A点处强度即可以下降40％～90％，这样就突破了设计制作超长距离胶带输送机的瓶颈。优选的，所述电动托辊16的旋转方向与所述传动滚筒1驱动所述胶带5运行的方向一致。
优选的，所述电动托辊16的工作电压是220v、380v、6kv、10kv和/或国际各国标准的电压。
所有的电动托辊16和驱动传动滚筒1的电动机8连接在多个变压器和开关控制的电源上。为了使电动托辊16和传动滚筒1同步，优选的，所述电动托辊16与所述传动滚筒1的启闭由一个共同开关进行控制。可选的，槽形上动力托辊2和下动力托辊4由启闭开关和/或变频器开关控制。开关启动后，电动托辊16和传动滚筒1即可同时开始驱动胶带5运行工作，多动力驱动的超长距离胶带输送机即可安全可靠地运行。由于所需的驱动力被有效分配，因此传动滚筒1、改向滚筒6、拉紧装置7、电动机8、液力耦合器9、减速机10、联轴器11等部件都可以降低40％～90％的规格型号，有效减小了安装施工所需的空间、费用以及施工难度。
多动力胶带输送机系统中的电动托辊16的电源线13从托辊轴17(参考图11)的中心孔引出来，如图3和图4所示。为了使电源线13从托辊轴17的中心孔引出来时独立而不相互干扰，优选的，所述电动托辊中的两侧槽形 上动力托辊2和之间的下动力托辊2设置于非一条直线上，如图5和图6所示。
参考图7～图10，平行下动力托辊或V形下动力托辊的安装，也要方便电源线13从托辊轴17的中心孔引出来。
如图11所示，多动力胶带输送机中配置的托辊轴承座24采用大过盈冷装配工艺装配，以保证电动托辊16两端托辊轴承23的同轴度和满足中间电动机转子21和定子22装配的精度要求。两端托辊轴承23密封采用腔式非接触密封结构组件25进行密封，以实现淋水和粉尘不污染，从而保证电动托辊16的正常使用，实现多动力胶带输送机在恶劣污染环境中的长期安全可靠运行。
如图12所示，优选的，多动力胶带输送机中配置的电动托辊16的管体材料采用钢管材料。此外，为了增加其与胶带5之间的摩擦力，优选的，在钢管管体外圆周利用滚花刀和/或滚花轮等方法制作成粗糙面26。同样的，电源线13从托辊轴17的中心孔引出来。
本发明提供的多动力胶带输送机将传统长距离胶带输送机中配置的被动托辊更换成为能够产生旋转驱动力的电动托辊，可将传统胶带强度、胶带与传动滚筒之间的圆周摩擦力、驱动传动滚筒1电机功率的40％～90％拆分给配置的电动托辊。可以有效减小总的配置功率。本发明提供的多动力胶带输送机可实现100公里以上的超长距离安全输送。特别是增加了胶带压紧辊结构之后，可进一步增大动力托辊的电机功率，从而增大其对胶带的驱动力，有效提高超长距离、尤其是上运大倾角输送的效率。通过胶带压紧辊和电动托辊对驱动力的双重提升，还可以适当减少动力托辊配置数量，达到节省成本的目的。此外，在动力托辊驱动胶带运行或胶带空载时，减少或避免动力托辊与胶带之间的打滑现象，提高了输送运输的安全可靠性。
