Abstract
The utility model belongs to the technical field of pipeline construction in petrochemical engineering, electric power, coal, water delivery and the like, and provides a roll wheel for a special-purpose hoisting tool for pipelines. The roll wheel mainly comprises steel hubs (4) and polyurethane bodies (5), and is characterized in that arc-shaped grooves for pasting the polyurethane bodies are formed in the excircle surfaces of the steel hubs (4); stepped through holes (6) for mounting a bearing seat are formed in both ends of each steel hub (4); and threaded holes (7) for fixing an end cover are formed in two end faces of each steel hub. According to the utility model, the arc-shaped grooves for pasting the polyurethane bodies are formed in the excircle surface of the roll wheel, so that the bonding area is increased, and the machining difficulty is low; and the arc-shaped structure is more favorable for the pouring, combination and formation of polyurethane. Therefore, the roll wheel has the characteristics of simple structure, convenience in machining, bonding firmness of the polyurethane bodies and the steel hubs, stability and reliability.
Description
Technical field
The utility model belongs to pipeline construction technology fields such as petrochemical industry, electric power, coal, water delivery, relates to a kind of running roller of pipeline special hanger.
Background technology
In order to guarantee pipeline anticorrosion surface outside hyposulculus does not damage, and efficient construction must be used the pipeline special hanger in pipeline constructions such as petrochemical industry, electric power, coal, water delivery; Like Fig. 1, shown in 2, the pipeline special hanger generally has suspension bracket 1, hawser 2, running roller assembly 3 to constitute, and four to six covers are an operation group during construction, with the supporting use of pipeline pipe sling, accomplish the operation of pipeline hyposulculus jointly; Its middle roll assembly 3 is as the critical component assembly of load, and its key is at running roller; Running roller is made up of steel wheel hub and polyurethane body, and the steel wheel hub has cast steel or steel section bar to process at present, and external process is wave channel or rectangular channel; Purpose makes in order to improve the polyurethane area of contact; Increase and axially to prevent polyurethane and steel wheel hub exfoliation ability, but this structure processed complex, and when filling polyurethane owing to the fluidity determining of liquid polyurethane it can not fill bottom land; Bubble can appear like this; More easy of crack causes polyurethane and steel wheel hub to come off when lifting, damage pipeline and scrapping.
The utility model content
The purpose of the utility model is the running roller that proposes a kind of pipeline special hanger, and it is simple in structure that it is had, easy to process, and polyurethane body and steel wheel hub are bonding firmly, reliable and stable characteristics.
The utility model adopts following technical proposals to accomplish its invention task:
A kind of running roller of pipeline special hanger, described running roller mainly comprises steel wheel hub and polyurethane body; On the periphery of said steel wheel hub, has arc groove in order to bonding polyurethane body; Have step through-hole at said steel wheel hub two ends, and on the both ends of the surface of steel wheel hub, have in order to the fixing tapped bore of end cap in order to the installation shaft bearing.
Described polyurethane body is a high-performance polyurethane elastomer.
The running roller of a kind of pipeline special hanger that the utility model proposes has the arc groove in order to bonding polyurethane body on the periphery of running roller, increased bond area, and difficulty of processing is low, and the camber structure more helps cast, combination, the moulding of polyurethane; Make to the utlity model has simple in structurely, easy to process, polyurethane body and steel wheel hub are bonding firmly, reliable and stable characteristics.

Fig. 1 is the structural representation of pipeline special hanger.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is the structural representation of the utility model.
Fig. 4 is the lateral plan of Fig. 3.
Among the figure, 1, suspension bracket, 2, hawser, 3, the running roller assembly, 4, the steel wheel hub, 5, polyurethane body, 6, step through-hole, 7, tapped bore.
The specific embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is explained:
Like Fig. 3, shown in 4, a kind of running roller of pipeline special hanger, described running roller mainly comprise steel wheel hub 4 and polyurethane body 5; On the periphery of said steel wheel hub 4, have the arc groove in order to bonding polyurethane body, increased bond area, and difficulty of processing is low, the camber structure more helps cast, combination, the moulding of polyurethane; Have step through-hole 6 at said steel wheel hub two ends, and on the both ends of the surface of steel wheel hub, have in order to the fixing tapped bore 7 of end cap in order to the installation shaft bearing.Steel wheel hub 4 and polyurethane body 5 are connected as a single entity through high performance adhesive among this embodiment;
The polyurethane body that is bonded among this embodiment on the wheel hub cylindrical is a high-performance polyurethane elastomer; Selection is the Vulkollan material of German Bayer company; Have splendid dynamic carrying capacity, excellent abrasive, high dynamic ductility and peel strength, minimum compressed residual deformability.
