Description
Technical field
The utility model relates to a kind of built block, is specifically related to a kind of pulley groove encapsulate high abrasion high-strength combination coaster.
Background technology
Along with the popularization that extra-high voltage grid is built, in trolley wire work progress, main construction method is tension stringing, and the most general mode of tension stringing is to use releasing pulley.But the problems such as the MC pulley encapsulate existence of combining in actual use, releasing pulley is not wear-resisting, insufficient strength.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of tearing toughness high, the anti-ability of pulling apart is strong, and hardness is moderate, casting type polyurethane elastomer pleiotaxy built block in the Novel sliding race of long service life.
Technical scheme: in order to solve the problems of the technologies described above, casting type polyurethane elastomer pleiotaxy built block in a kind of Novel sliding race described in the utility model, it comprises frame and suspension plate, described suspension plate is arranged on the top of frame, between described frame, assembly pulley is set, described assembly pulley comprises interior pulley and outer pulley, and described assembly pulley is connected with frame by bearing, is provided with polyurethane rubber layer in described pulley groove.
Described interior pulley is MC nylon pulley.
Described polyurethane rubber layer is that cast-type is fixedly connected with wheel chute.
Described bearing is band dust cap zanjon bearing.
Described polyurethane rubber layer is made up of three arc rubber segments, is respectively the first arc rubber segments, the second arc rubber segments and the 3rd arc rubber segments.
The radius R of described the first arc rubber segments is 40mm.
The radius R of described the second arc rubber segments is 19mm.
The radius R of described the 3rd arc rubber segments is 40mm.
Polyurethane physical and mechanical properties is listed as follows:
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, in described pulley groove, be provided with polyurethane elastomer, described polyurethane elastomer is that cast-type is fixedly connected with wheel chute, polyurethane elastomer has higher tension, resistance to compression, tearing toughness, simultaneously resistance to flexural fatigue, wear-resisting, ageing-resistant, elasticity is high, elongation is high, whole service life is long, realistic instructions for use.
