The utility model relates to a wear-resisting lower roller of a belt conveyor, which relates to the wear-resisting roller field of a belt conveyor, including a metal roller tube, a metal roller tube with a non-metal wear-resisting tube, a clamp strip on the outer wall of the metal roller tube parallel to the axis line of the metal roller tube, the shape of the clamp strip is similar to a trapezoid, the top surface is an arc surface, and the arc surface and the metal roller. The outer wall of the pipe is identical. The non-metallic wear-resistant pipe is made up of A tube and B tube. A tube and B tube are provided with clamping grooves which fit with clamps. The inner and outer walls of A tube and B tube are respectively provided with ring protrusions. The ring protrusions are blocked at both ends of the metal roller tube. Two wedge-shaped splicing pieces and two wedge-shaped splicing pieces are fixed on the splicing end face of A tube. The inclined plane is respectively provided with triangular splicing protrusions, and the splicing end of the B tube is provided with a notch that matches the wedge splicing part on the A tube and the splicing protrusion. The wear-resistant lower roller of the belt conveyor has strong wear resistance, is not easy to be damaged under the pressure of the belt and the clapping, and has a long service life.

皮带机耐磨下托辊
本技术涉及皮带机耐磨托辊领域,尤其涉及一种皮带机耐磨下托辊。
技术介绍
下托辊一般用在回转空载皮带上,传统的皮带机下托辊为普通钢管制作。上托辊一般间隔1米设置一件,而下托辊一般间隔3米设置一件,下托辊之间的间隔距离相对较大,皮带高速运行时,会出现拍打下托辊的现象,拍打的同时出现滑动摩擦,下托辊在承受滚动摩擦的同时,还承受着对它损坏极大的滑动摩擦,加之井下环境潮湿,传统的金属托辊很容易磨损、生锈,使用寿命短,现有技术中出现了耐磨非金属托辊,然而,普通的耐磨非金属托辊虽然耐磨性较强,但刚度不足,不够结实,在皮带的压力和拍打下容易损坏。
技术实现思路
为了解决现有皮带机下托辊耐磨性差、易损坏的问题,本技术提供了一种皮带机耐磨下托辊,耐磨性强、在皮带的压力和拍打下不易损坏,使用寿命长。本技术是通过下述技术方案来实现的:一种皮带机耐磨下托辊,包括金属托辊管,其特征是,所述金属托辊管外还套有非金属耐磨管,所述金属托辊管外壁上设有与金属托辊管轴心线相平行的卡条,所述卡条的外形为类似梯形体,与梯形体的不同在于顶面为弧形面,所述的弧形面与金属托辊管的外壁相吻合,焊接在金属托辊管的外壁上,所述非金属耐磨管由A管和B管拼接而成,所述的A管和B管内设有与卡条相契合的卡槽,A管和B管的内壁外端分别设有环状凸起,所述环状凸起挡在金属托辊管的两端,所述A管的拼接端端面上固定有2个楔形拼接件,所述楔形拼接件的两个斜面上分别设有三角状的卡接凸起,所述B管的拼接端设有与A管上楔形拼接件和卡接凸起相契合的豁口。在本技术的另一个方面中,所述的2个楔形拼接件之间的连线与非金属耐磨管的 ...
