摘 要

在带式输送机运转过程中,输送带的纵向中心线偏离输送机理论中心线的现象称输送带跑偏。它的表现是输送带边缘至托辊或滚筒边缘的距离与理论值相比或大或小。输送带的跑偏会使输送带与机架、托辊支架相摩擦,造成边胶磨损。严重的跑偏会使输送带翻边,若在滚筒表面边缘有凸起的螺丝头、覆盖胶层局部剥离、划伤等事故。跑偏会导致输送机的事故停机次数增多,影响生产;跑偏还可能引起物料外撒,使输送机系统的运营经济性下降。

为此,曲柄连杆式自动调偏装置最突出的特色是曲柄连杆机构。调偏架通过滚动轴承安装在底座上,两端对称连接制作的连杆,连杆末端固定立辊。安装在曲柄上的两侧立辊靠近输送带边缘,一有跑偏出现,输送带就压向该侧立辊,使立辊随着曲柄向外转动,曲柄和连杆拉动调偏架按输送带运行方向旋转一定角度,从而产生调偏。

Summary
While the bringing type conveyer operates, the phenomenon that the longitudinal centre line of the conveyer belt deviates from the mechanism of transporting and talks about the centre line claims the conveyer belt runs partially. Its behavior is either large or small on compared with theory value to holding the distance on the roller or edge of cylinder the edge of conveyer belt. The running and leaning towards and will enable conveyer belt and framework, ask the roller support to rub of conveyer belt, cause the glue is worn and torn. A serious one run, lean towards, can enable conveyer belt turn-ups, if surface edge have protruding screw head, cover glue layers of part strip, accident of scratching etc. in cylinder. Run, lean towards, can lead to the fact accident of conveyer shut down number of times increase, influence and produce; Run, may cause supplies let go also simply, make conveyer economic decline of operation of system.
For this reason, it is the crank connecting rod organization that the crank connecting rod type adjusts and leans towards the most outstanding characteristic of the device automatically. Adjust and lean towards the shelf and install the connecting rod made of the symmetrical connection of both ends on the base through the rolling bearing, the connecting rod sets up the roller terminal fixedly. Both sides that are installed on the crank set up the roller close to the edge of conveyer belt, run and simply appear, conveyer belt press to should incline, set up roller, make, set up roller rotate outwards with the crank, the crank and connecting rod spur and adjust and lean towards the shelf to rotate certain angle according to the conveyer belt operation direction, thus produced and adjusted partially.
