Abstract

The utility model relates to a polyurethane ground roller and fixing device. The polyurethane ground roller and fixing device is provided with a pillow plate which is transversely paved; two ends of the pillow plate are respectively provided with a shaping pressing plate and a locking projection; a pressing plate support is installed between every locking projection and a rail base; a polyurethane ground roller is assembled between the two pressing plate supports; two ends of the polyurethane ground roller are provided with stepped expansion holes; internal sides of the expansion holes and outer rings of a radial bearing are tightly installed in a matching mode; inner rings of the bearing are sequentially provided with central shafts, circular-ring-shaped sealing rings and closely adhered fixing snap rings in a matching mode. The polyurethane ground roller and fixing device has the advantages of being high in mechanical strength, good in abrasive resistance, oil resistance, low temperature resistance, ozone resistance and radiation resistance and long in service life and bringing great convenience for worker construction.

Description

Polyurethane ground roll and anchor fitting

Technical field

the utility model relates to a kind of polyurethane ground roll and anchor fitting that ground roll, especially elasticity are high, wear resisting property is good that software load-transfer device or steel rope are guided.

Background technology

at present, under colliery or in building operation place, generally by ground roll, come software load-transfer device or steel rope, the travel direction guiding in moving process of the linear object of the softwares such as nylon rope, existing ground roll is many to be made by cast iron, cast steel, steel pipe or forging, in the process of using, is easy to be corroded, and wear resisting property is poor, when too high or too low for temperature, easily there is deformation, had a strong impact on the service life of ground roll.

Utility model content

in order to solve the problem that existing ground roll wear resisting property is poor and the life-span is short, the utility model provides a kind of polyurethane ground roll and anchor fitting, this polyurethane ground roll and anchor fitting not only have higher mechanical strength, and in broad durometer level, still there is good elasticity, the performance of excellent resistance to abrasion, oil resistant, low temperature resistant, resistance to ozone and radiation, even in severe construction environment, also can use for a long time and can not be out of shape, in the service life that has effectively extended ground roll, to construction operation, bring great convenience.

the utility model solves the technical scheme that its technical matters adopts: this polyurethane ground roll and anchor fitting comprise, bearing, polyurethane ground roll, seal ring, snap ring, center shaft, this device is provided with the pillow plate that an integral body that is laterally laid on track below is lath-shaped, pillow plate two ends are sequentially with respectively typing pressure plate and the vertical side of the side stop protrusion with a slope with the tight interlock of rail bed one side, between stop protrusion and rail bed, joint match is equipped with the plate bracket of " L " type, between two plate brackets, be fitted with polyurethane ground roll, polyurethane ground roll two ends have step reaming, the installation that closely cooperates of reaming inner side and radial bearing outer shroud, bearing inner ring matching order is provided with center shaft, annular seal circle and the fixedly snap ring of being close to, described seal ring closely pushes up is pressing bearing inner ring, and closely fixing with center shaft, seal ring outside is with the detent projection of holding grease, between it and polyurethane ground roll reaming wall, be with gapped, do not contact with hole wall, seal ring presses bearing inner ring one side, with a staircase structural model space, it does not contact with outer race, when polyurethane ground roll is rotated, polyurethane ground roll does not contact with outer race with seal ring and seal ring, add the lubricated of grease, all the time can make polyurethane ground roll keep good running state, therefore can be by the life 2-3 of polyurethane ground roll doubly.

the beneficial effects of the utility model are, this polyurethane ground roll and anchor fitting not only have higher mechanical strength, and in broad durometer level, still there is good elasticity, the performance of excellent resistance to abrasion, oil resistant, low temperature resistant, resistance to ozone and radiation, even in severe construction environment, also can use for a long time and can not be out of shape, effectively extended the service life of ground roll, to workman's construction, brought great convenience.

Accompanying drawing explanation

below in conjunction with drawings and Examples, the utility model is described in further detail.

fig. 1 is the cross-section structure principle schematic of polyurethane ground roll.

fig. 2 is the fixture structure principle schematic of polyurethane ground roll.

in figure, 1. step in roller, 2. bearing, 3. polyurethane ground roll, 4. seal ring, 5. snap ring, 6. center shaft, 7. track, 8. plate bracket, 9. typing pressure plate, 10. pillow plate, 11. stop protrusion.

The specific embodiment

in the drawings, this polyurethane ground roll and anchor fitting comprise, bearing 2, polyurethane ground roll 3, seal ring 4, snap ring 5, center shaft 6, this device is provided with the pillow plate 10 that an integral body that is laterally laid on track 7 belows is lath-shaped, pillow plate 10 two ends are sequentially with respectively typing pressure plate 9 and the vertical side of the side stop protrusion 11 with a slope with the tight interlock of track 7 base one side, between stop protrusion 11 and track 7 bases, joint match is equipped with the plate bracket 8 of " L " type, between two plate brackets 8, be fitted with polyurethane ground roll 3, polyurethane ground roll 3 two ends have step reaming, the installation that closely cooperates of reaming inner side and radial bearing 2 outer shrouds, the interior ring matching order of bearing 2 is provided with center shaft 6, annular seal circle 4 and the fixedly snap ring 5 of being close to, described seal ring 4 is closely being pressed the interior ring of bearing 2 in top, and closely fixing with center shaft 6, seal ring 4 outsides are with the detent projection of holding grease, between it and polyurethane ground roll 3 reaming walls, be with gapped, do not contact with hole wall, seal ring 4 presses interior ring one side of bearing 2, with a staircase structural model space, it not with the outer loop contacts of bearing 2, when polyurethane ground roll 3 is rotated, polyurethane ground roll 3 does not contact with bearing 2 outer shrouds with seal ring 4 and seal ring 4, add the lubricated of grease, all the time can make polyurethane ground roll 3 keep good running state, therefore can be by the life 2-3 of polyurethane ground roll 3 doubly.
