The invention discloses a wear-resistant winch lane ground roller which comprises a cylinder body (1). The cylinder body (1) and a check ring (2) are cast into a whole, and a hole (11), a bearing cup (3) and a piston ring groove (12) are formed in the cylinder body (1); a shaft (5) is arranged in the hole (11), two bearings (4) and a bearing gland (9) are respectively arranged on the shaft (5), and two piston rings (10) are respectively arranged in the piston ring groove (12); the two ends of the shaft (5) are installed on planes of the two sides of a tunnel (7) through supports (6); casting materials of the cylinder body (1) and the check ring (2) are wear-resistant alloy steel materials; and a layer of hard alloy material is coated on the surface of the cylinder body (1). By means of the wear-resistant winch lane ground roller, the problem that in the prior art, a bearing gland and a bolt head are prone to being abraded is solved; and the cylinder body and the check ring are not easy to wear through, so that the service life is greatly prolonged, and the material cost is reduced.
本发明公开了一种耐磨型绞车道地辊,它包括筒身(1),筒身(1)与挡圈(2)铸造成一体,在筒身(1)内制成孔(11)、轴承杯(3)和涨圈槽(12);轴(5)安装在孔(11)内,轴(5)上分别安装两个轴承(4)和轴承压盖(9),两个涨圈(10)分别安装在涨圈槽(12)内;轴(5)两端通过支架(6)安装在地道(7)的两侧平面上。所述的筒身(1)与挡圈(2)铸造材料为耐磨合金钢材料。所述的筒身(1)表面涂覆一层硬质合金材料。本发明消除了现有技术存在的轴承压盖及螺栓头易被磨坏的问题;且筒身及挡圈都不易被磨穿,因此大大延长了使用寿命,降低了材料成本。
