The utility model discloses a belt pressing device for downward groove belt conveyor with large slope, which comprises an epithelial belt pressing device and a lower belt pressing device. The epithelial belt pressing device comprises two upper pressure pulleys, the upper pressure pulley is installed on the support shaft, and the support shaft is installed on two main brackets through the support of the pressure pulley located at both ends of the belt conveyor; the lower belt pressing device comprises a downward pressure belt drum and a main cross beam. The main transverse beam is connected with the fixed plate located on the outer side of the two main supports by a plurality of bolts; the roller in the downward pressure belt drum is fixed on the fixed seat on both sides of the roller, and the fixed seat is connected with the steel plate located above the main transverse beam by a plurality of bolts, i.e., the downward pressure belt drum is suspended on the main transverse beam; the bottom of the main support is installed with a base, and the upper part of the main support is also installed with a telescopic frame, and the top of the telescopic frame is installed. The end contacts the roof. The device plays a very good role in preventing the belt from running off and rising, ensuring the normal operation of the belt conveyor for a long time, and reducing the incidence of failure.

大坡度下行顺槽皮带机压带装置
本技术涉及顺槽皮带机的安全运行领域,具体为一种大坡度下行顺槽皮带机压带装置,适用于皮带运输机变坡段使用。
技术介绍
在煤矿中,根据矿井生产衔接情况,部分掘进巷道变坡点成型坡度大,顺槽皮带机稳装困难,皮带运行安全隐患大。结合巷道掘进情况,由于拉紧段后方有大倾角爬坡段,皮带机运行过程中容易出现飘带现象,制动过程中易打滑,引起皮带机制动不及时,造成堆煤现象。为了防止皮带跑偏上扬,减少机电运输故障,降低事故率,保证皮带机正常拉运时间,提高综采工作面的产能,需要一种皮带机压皮带装置来保证皮带机停机过程的安全、平稳。
技术实现思路
本技术为了解决皮带运输机在大坡度运行情况下的皮带跑偏上扬,容易引起多种故障的问题,提供了一种大坡度下行顺槽皮带机压带装置。本技术是通过如下技术方案来实现的:一种大坡度下行顺槽皮带机压带装置,包括上皮带压带装置和下皮带压带装置,所述上皮带压带装置包括两个上压带轮,所述上压带轮安装于支撑轴上,所述支撑轴通过位于其两端的压带轮支座安装于两个主支架上,所述压带轮支座通过多个螺栓与位于两个主支架外侧的钢板连接;所述下皮带压带装置包括下压带滚筒和主横梁,所述主横梁通过多个螺栓与位于两个主支架外侧的固定板连接;所述下压带滚筒内的滚轴固定于滚轴两侧的固定座上,所述固定座通过多个螺栓与位于主横梁上方的钢板连接,即所述下压带滚筒悬吊于主横梁上;所述主支架底部安装有底座,所述主支架上部还安装有伸缩架,所述伸缩架的顶端与顶板接触。本技术是为了给大坡度运行的皮带运输机压皮带而设计的,皮带输送机分为上托辊和下托辊,因此皮带就分为上皮带和下皮带 ...
