Abstract

The utility model discloses a winch way ground roller which comprises a cylinder body (1), wherein the cylinder body (1) and a retainer 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); the shaft (5) is arranged in the hole (11), the shaft (5) is respectively provided with two bearings (4) and a bearing gland (9), and the two piston rings (10) are respectively arranged in the piston ring groove (12); two ends of the shaft (5) are arranged on planes at two sides of the tunnel (7) through a bracket (6). The casting materials of the cylinder body (1) and the retainer ring (2) are wear-resistant alloy steel materials. The surface of the cylinder body (1) is coated with a layer of hard alloy material. The utility model eliminates the problem that the bearing gland and the bolt head are easy to be worn out in the prior art, and the cylinder body and the retainer ring are not easy to be worn through, thereby greatly prolonging the service life and reducing the material cost.

Description

Ground roller of winch way

Technical Field

The utility model relates to a mining winch track ground roller.

Background

As shown in figure 1, a winch track ground roller in the prior art adopts a steel pipe as a cylinder body, and two ends of the steel pipe are welded with a check ring and a bearing cup; the bearing gland is pressed by the bolt, the bearing gland and the bolt head exceed the planes of the two end faces of the ground roller, the cylinder body is easily worn by the steel wire rope in the using process, and meanwhile, the exposed bearing gland and the exposed bolt head are easily worn by the steel wire rope which is bounced outside the retainer ring. The whole ground roller is likely to be scrapped after the cylinder body is worn through and the bearing gland is worn out, so that the service life of the original ground roller is greatly reduced. Therefore, there is a need to develop a wear resistant type winch way ground roll.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a novel floor roller of a winch way, which overcomes the defects that the service life of the floor roller of the winch way is short and the like caused by the fact that a cylinder body is easy to wear through and a bearing gland is easy to wear.

The utility model adopts the following technical scheme: the cylinder body and the retainer ring are cast into a whole, and a hole, a bearing cup and a piston ring groove are formed in the cylinder body; the shaft is arranged in the hole, the shaft is respectively provided with two bearings and bearing glands, and the two piston rings are respectively arranged in the piston ring grooves; the two ends of the shaft are arranged on the planes at the two sides of the tunnel through a bracket.

The casting material of the cylinder body and the check ring is wear-resistant alloy steel material.

The surface of the cylinder body is coated with a layer of hard alloy material.

The utility model casts the cylinder body, the bearing cup and the retainer ring into a whole, the concave depth of the bearing cup is increased, the bearing gland is arranged in the bearing cup, the piston ring is arranged in the piston ring groove to press the bearing gland, the outermost edges of the bearing cup and the piston ring of the hole do not exceed the planes of the two end surfaces of the ground roller body, and the piston ring replaces a bolt to press the bearing gland, thereby eliminating the problem that the bearing gland and the bolt head are easy to be worn out in the prior art. Because the casting adopts wear-resistant alloy materials, the cylinder body is thickened, or the surface of the cylinder body is coated with a layer of high wear-resistant materials, and the cylinder body and the check ring are not easy to wear through, thereby greatly prolonging the service life. Moreover, the wear-resistant alloy material adopted by the casting can be repeatedly cast and utilized after being repaired or scrapped, so that the material cost is reduced.

In the figure, 1-cylinder body, 2-retainer ring, 3-bearing cup, 4-bearing, 5-shaft, 6-support, 7-tunnel, 8-bolt, 9-bearing gland, 10-piston ring, 11-hole, 12-piston ring groove.

Detailed Description

The embodiment of the utility model comprises the following steps: the cylinder body 1 and the retainer 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; the shaft 5 is arranged in the hole 11, the shaft 5 is respectively provided with two bearings 4 and bearing glands 9, and the two piston rings 10 are respectively arranged in the piston ring grooves 12; the shaft 5 is mounted at both ends on both side planes of the tunnel 7 by brackets 6.

The casting materials of the cylinder body 1 and the retainer ring 2 are wear-resistant alloy steel materials.

The surface of the cylinder body 1 is coated with a layer of hard alloy material.

The ground roller body, the bearing cup and the retainer ring are cast into a whole, the concave depth of the bearing cup is increased, the bearing gland is arranged in the bearing cup, the piston ring is arranged in the piston ring groove to press the bearing gland tightly, the outermost edges of the bearing cup and the piston ring do not exceed the planes of the two end faces of the ground roller body, and the piston ring replaces a bolt to press the bearing gland tightly. The problems that the roller body of the original roller is easy to wear through and the bearing caps and the bolt heads on the two end faces are easy to wear are solved, and the service life of the ground roller is greatly prolonged; the casting process is adopted, so that the integrity is good; the wall thickness is thickened, and the service life is prolonged.

In the use process, after the bearing is damaged, the piston ring can be replaced after being taken down, and the repair and the utilization are convenient.
