进一步，所述的驱动电机1设为正反转电机，通过正反转电机控制旧皮带14的更换和新皮带13的缠绕，以及旧皮带14的卸下和新皮带13的更换。
进一步，所述的上托辊8和下托辊9的两端分别设有上挡板24和下挡板25，所述的上挡板24和下挡板25分别限制缠绕和释放皮带的方向，方便皮带方向的定位。
进一步，所述的门型架体中的横向支架10中部设有激光灯座26，激光灯座26的前后两侧分别安装激光灯27，通过激光灯27发射的激光线观察皮带缠绕或释放情况，出现偏移可及时更正。
进一步，所述的门型架体中左支架11和右支架12的下端分别设有横向底座28，横向底座28的下端设有与横向底座28连接的万向轮29，横向底座28的前后两侧分别设有斜撑杆30，斜撑杆30分别与左支架11与横向底座28或右支架12与横向底座28之间相互连接，通过斜撑杆30增大整体稳定性。
本发明的更换方法的步骤如下：首先将该专用支架通过横向底座28上的万向轮29移动至皮带机中部位置，打开激光灯27，通过激光灯27发射的激光线处于皮带机中部位置，同时观察皮带缠绕或释放情况，出现偏移可及时更正，将然后将皮带机上的旧皮带14切割开，切割后的旧皮带14的两端连接工字型的连接卡子17位置打孔，然后将切割后的前侧的旧皮带14端部经连接卡子17与上托辊8上的新皮带13相连接，然后将切割后的后侧的旧皮带14端部经连接卡子17与下托辊9上的上过渡连接带15相连接，再启动驱动电机1正转，驱动电机1带动上托辊8和下托辊9同步转动，上托辊8转动将新皮带13卸下，下托辊9转动将旧皮带14缠绕收纳，出现偏移可及时更正，当旧皮带14收纳完成，新皮带 13释放完成后，分别将新皮带13与旧皮带14之间连接的工字型的连接卡子17卸下，将新皮带13与上过渡连接带15之间的连接卡子17卸下，再将卸下后的新皮带13的两端相互连接，实现了新皮带13的更换，更换完成后移走该专用支架，再通过启动驱动电机1反转，将上托辊8上的上过渡连接到通过工字型的连接卡子17与新皮带13的一端相连接，缠绕新的需要待更换的皮带，下托辊9将旧皮带14通过电机反转卸下，待需要再进行皮带更换时，将该专用支架直接移动即可，由于采用上述结构及更换皮带方法，具有结构简单、使用方便、安装效率高、安装效果好、安全性高等优点。
上述所述的更换方法中，工字型的连接卡子17的两端分别插入新皮带13、旧皮带14或上过渡连接带15、下过渡连接带16，分别实现了新皮带13与旧皮带14、新皮带13与上过渡连接带15、旧皮带14与下过渡连接带16之间的连接，同时可以初步设为图2中驱动电机1正转为上托辊8和下托辊9顺时针方向旋转，而且上托辊8顺时针旋转为皮带释放过程，下托辊9顺时针转动为皮带收纳缠绕过程，上托辊8的前侧方向与旧皮带14的一端连接，下托辊9的后侧方向与旧皮带14的另一端相连接，旧皮带14的两端分别设在门型架体的前后两侧，通过电机转动可同时进行新皮带13的释放和旧皮带14的收纳，下托辊9拉动旧皮带14的收纳，工字型的连接卡子17可以设在皮带的连接端面的中部和两端，方便连接固定同时也方便拆卸，在更换皮带的过程中，皮带机自身的托辊不受驱动设备控制，其可自由转动，可被下托辊拉动旧皮带的过程中转动。
