Abstract
The utility model relates to a roller for belt conveyors, and particularly relates to an all-cast-steel roller. The utility model solves the problems that in the process of using the existing roller, the internal stress is concentrated, a roller skin is easy to sink, and a roller body is easy to have an out-of-balance rotation phenomenon. The all-cast-steel roller comprises a roller body and a roller skin, wherein the roller skin is directly sleeved on the outside surface of the roller body; the roller body is an integral roller body; and the inside surface of the middle part of the roller skin is fixedly embedded with a ring-shaped reinforced rib. By using the all-cast-steel roller provided by the utility model, the problems that in the process of using the existing roller, the internal stress is concentrated, a roller skin is easy to sink, and a roller body is easy to have an out-of-balance rotation phenomenon are effectively solved, therefore, the all-cast-steel roller is suitable to be applied to belt conveyors.
Description
Technical field
The utility model relates to band conveyor and uses cylinder, specifically is a kind of full cast steel cylinder.
Background technology
Cylinder is the important component part of band conveyor, and it mainly is made up of cylindrical shell and tube skin two parts, and during use, barrel jacket is connected on the main shaft of band conveyor, and cylinder is rotated around main shaft.At present, the tube skin of cylinder is mainly rolled by steel plate and forms or adopt solid drawn pipe to process, and cylindrical shell then adopts one longitudinal seam and two road circumferential welded seams to be welded.The cylinder that adopts said structure is in use easily because of weld cracking or the long set up stresses of cylindrical shell is concentrated, a tube skin collapses recessed easily and the cylindrical shell unbalanced phenomenon of rotation easily; Just can cause the main shaft fracture of band conveyor thus, thereby damage entire equipment.Be necessary the structure of existing cylinder is improved, in use stress concentration, tube skin collapse recessed and the unbalanced problem of the easy rotation of cylindrical shell easily to solve it for this reason.
Summary of the invention
The utility model for solve existing cylinder in use stress concentration, a tube skin collapse recessed easily and the cylindrical shell unbalanced problem of rotation easily, a kind of full cast steel cylinder is provided.
The utility model is to adopt following technical scheme to realize: full cast steel cylinder, the tube skin that comprises cylindrical shell and be socketed on the cylindrical shell outer surface; Said cylindrical shell is an integral cylinder; Tube skin middle part inner surface build-in has ring stiffener.
During use, barrel jacket is connected on the main shaft of band conveyor.Because cylindrical shell is an integral cylinder, avoided cylinder in use because of the weld cracking set up stresses is concentrated, the tube skin collapses recessed and cylindrical shell rotation overbalance, avoided the main shaft fracture of band conveyor thus.The effect of ring stiffener is to increase the rigidity of cylindrical shell, has avoided cylinder in use to produce a tube skin because of cylindrical shell is long and has collapsed recessedly, makes that thus main shaft obtains excellent protection.Compare with existing cylinder; The described full cast steel cylinder of the utility model is through adopting integral cylinder and setting up ring stiffener; Efficiently solve existing cylinder in use stress concentration, a tube skin collapse recessed easily and the cylindrical shell unbalanced problem of rotation easily, thereby protected the main shaft of band conveyor effectively.
The utility model is simple in structure, reasonable in design, efficiently solve existing cylinder in use stress concentration, a tube skin collapse recessed easily and the cylindrical shell unbalanced problem of rotation easily, be applicable to band conveyor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure: 1-cylindrical shell, 2-tube skin, 3-ring stiffener.
The specific embodiment
Full cast steel cylinder, the tube skin 2 that comprises cylindrical shell 1 and be socketed on cylindrical shell 1 outer surface; Said cylindrical shell 1 is an integral cylinder; Tube skin 2 middle part inner surface build-ins have ring stiffener 3;
During practical implementation, said integral cylinder adopts the molten steel disposal pouring to form; Cylindrical shell and tube skin are all through bakingout process; Tube skin outer surface is provided with screw thread, and said screw thread is divided into left-hand thread and right-hand thread, and left-hand thread is located at a skin left part outer surface and a skin right part outer surface respectively with right-hand thread.
