CN205471197U - Quick -witted head pulley anti -skidding is partially ended in silica sand transportation area - Google Patents

Abstract

The utility model relates to a silicon the sand production facility, quick -witted head pulley anti -skidding is partially ended in silica sand transportation area promptly, its characteristics are: machine head pulley's (1) diameter is small in ends broad in the middle, and the sectional outward flange of its axial is pitch arc (3). The beneficial effects are that: the belt is cross curvature form parcel and on quick -witted head pulley, is difficult for laterally offset, has also strengthened the friction dynamics with quick -witted head pulley simultaneously to has played the effect that prevents the off tracking and skid, has especially adopted the quick -witted head pulley of steel reinforcement cage form, further increaseed the friction effect of warpout head pulley and belt, better solution the off tracking problem of skidding, and simple structure, low in cost, convenient to use is expected to become the indispensable equipment of silica sand washing.

Description

Silica sand conveyer belt stops the most anti-skidding head pulley

Technical field

This utility model relates to a kind of silica sand and produces equipment, and i.e. a kind of silica sand conveyer belt stops the most anti-skidding head pulley.

Background technology

Being transported the raw materials such as silica sand by conveyer belt is processing step conventional in silica sand washing process, and conveyer belt is many It is made up of head pulley and belt etc..Head pulley is also referred to as belt pulley, but more wider than general belt pulley, And set up the two ends at conveyer belt separately.Existing head pulley mostly is cylindric, and two ends have axle to be arranged in frame. Owing to silica sand is difficult to accurately than great and filling position, belt deviation is usually caused to skid.Belt deviation will Move to one end of head pulley, cause transmission uneven and edging tearing tape accident.Skidding can reduce the work of belt Make efficiency, increase operating cost.Therefore, this problem is all being managed to solve in washed-out sand workshop, but the most still without Satisfied technical measures.

Summary of the invention

The purpose of this utility model is to provide a kind of it can be avoided that the silica sand conveyer belt of sideslip and skidding.

Above-mentioned purpose is realized by techniques below scheme: develops a kind of silica sand conveyer belt and stops the most anti-skidding head pulley, Being characterized in: the diameter of described head pulley is small in ends broad in the middle, the outward flange of its axial section is camber line.

The outer surface of described head pulley is the basket surrounded by branched reinforcing bar.

The outer surface of described head pulley is provided with multiple boss.

The outer surface of described head pulley is provided with a plurality of longitudinal fin.

The beneficial effects of the utility model are: belt is that transverse curvature shape is wrapped on head pulley, are difficult to lateral Skew, also strengthens the friction dynamics with head pulley simultaneously, thus serves the effect preventing sideslip from skidding, Especially with reinforcing bar caged head pulley, increase the friction effect of head pulley and belt further, preferably Solve the problem that sideslip skids, and simple in construction, cheap, it is simple to use, it is expected to become silica sand and wash The necessary equipment of choosing.

Detailed description of the invention

The first embodiment: as shown in Fig. 1 Fig. 2, this silica sand conveyer belt stops the most anti-skidding head pulley, and commonly Head pulley closely similar, be also two ends cylinders of installing wheel shaft 2, except that, the post of head pulley Body is not the cylinder of a standard, but thick between the detail of two ends, and i.e. axially section outward flange is the ball of camber line Cylinder.Visible in conjunction with Fig. 3, belt 4 is arranged on above this head pulley 1, owing to belt 4 is soft, The plasticity of shape is big, will be coated on the outside of head pulley in bending, thus be difficult to move left and right.Greatly Amount experiment proves: even if the material position transported is less accurate, belt also will not sideslip.In like manner, due to skin Band and head pulley are buckled togather by curved surface, contact more tight each other, and frictional force is also significantly increased, The ratio skidded is significantly reduced, and transmission efficiency significantly improves, and transaction capabilities is remarkably reinforced.

The second embodiment: the silica sand conveyer belt that Fig. 4 Fig. 5 Fig. 6 is introduced stops the most anti-skidding head pulley, is the Improve, in addition to keeping the feature of its spherical cylinder, outside head pulley 1 on the basis of a kind of embodiment Surface is the basket surrounded by branched reinforcing bar 6.Gap is left between reinforcing bar 6, compared with the contact of the face of precedent, Between reinforcing bar 6 and belt 4, contact area is greatly reduced, i.e. pressure significantly increases, and its frictional force increases the most therewith, The problem that can preferably solve to skid.

Certainly, reinforcing bar 6 described here and the hard material of other similar shapes are equivalents.

The third embodiment: as it is shown in fig. 7, this head pulley 1 is also a kind of spherocylinder, its outer surface sets Having multiple boss 7, page can play increasing friction force, prevents the effect skidded.

4th kind of embodiment: as shown in Fig. 8 Fig. 9, the surface of this head pulley 1 is provided with a plurality of longitudinal fin 8, it is also possible to play increasing friction force, prevent the effect skidded.

Claims (1)
