Abstract
The utility model relates to an automatic stabilization and protection device of a belt, which comprises a rotary drum, a hollow tube and a middle support shaft, wherein both ends of the middle support shaft are fixed on a supporting device, the middle support shaft is sleeved with the hollow tube, a gap is left between the hollow tube and the middle support shaft, the perpendicular bisector of an axis of the middle support shaft is provided with a rotatable pivot, both ends of the pivot are fixedly connected with the hollow tube, the rotary drum is sleeved on the hollow tube, a bearing is arranged between the hollow tube and the rotary drum, and a sealing device is arranged outside the bearing. The automatic stabilization and protection device of the belt disclosed by the utility model has a simple structure, deviation is quickly rectified by the deviation trend, the deviation rectifying effect is good, the service life of the belt can be prolonged, and the production cost is saved.
Description
Technical field
The utility model relates to a kind of sideslip correct equipment of travelling belt, particularly a kind ofly can stablize fender guard from the belt of dynamic correction belt deviation.
Background technology
Along with the continuous development of science and technology, the mechanization level in colliery improves constantly, and belt transporter has become the main tool that coal is transported in the colliery.Belt transporter is subjected to the influence of various factors such as load inequality, belt bur and thickness of belt difference in the course of the work, and the various deviation accumulation in the back that works long hours cause belt sideslip on carrying roller, i.e. line direction out of plumb carrying roller axis before the belt.Behind the sideslip, the side of belt and adjacent thing can rub, and increase motor load, not only influence normal transport, and also fragile equipment brings potential safety hazard.
At present, almost various belt transporters all are equipped with the sideslip correct equipment, to guarantee ordinary production, safety in production.Though existing belt stabilizing device has played certain mitigation for proofreading and correct sideslip, does not tackle the problem at its root, correction work is passive adjustment mode, behind belt deviation and edge contact side roller, entire bracket is rotated an angle, makes belt get back to the normal position.Because the hysteresis quality of its action, rectifying effect is not very desirable, and belt edge is long-term and the friction of side roller, has also quickened the damage of belt edge.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and the belt autostable fender guard of a kind of compact conformation, easy for installation, dependable performance, automatic compensation belt deviation is provided.
Belt autostable fender guard of the present utility model comprises cylinder, hollow and middle holder axle; the two ends of middle holder axle are fixed on the bearing set; on middle holder axle, be with hollow; leave the gap between hollow and the middle holder axle; one rotating pivot is installed on the midperpendicalar of middle holder axis, captives joint with hollow in the two ends of pivot, and drum sleeve is on hollow; between hollow and cylinder bearing is installed, bearing is equipped with sealing arrangement outward.
Further, also be enclosed with a clad at the outside face of described cylinder, described clad is soft rubber or the wear-resisting material of polyurethane, and the two edges of clad and centre portion maintain certain tapering, and described tapering is not more than 3 °.
In addition, described sealing arrangement is a labyrinth-type excluder, can select the labyrinth-type excluder of arbitrary structures.
The utility model has following advantage compared with prior art:
Belt autostable fender guard inside of the present utility model is contained one and is contained in the corrosion-resistant steel pivot on the holder axle in the solid dead-soft steel; utilize the special conical section in cylinder clad two; cause the pivot rotation of supporting-point roller, make belt remain on middle position around its central vertical.
Belt autostable fender guard of the present utility model can be reduced friction, and prolongs the service life of belt, and that reduces the maintenance capacity of accessory and material spills the reduction operating cost, is adapted at working various harsies environment under.Since in the surface coverage of supporting-point roller flame retardant rubber, guaranteed that belt conveyor and the good of supporting-point roller surface contact and friction, labyrinth-type excluder has been guaranteed effective seal under rugged environment.That the utility model device is installed is simple and easy, running is shockproof, is easy under condition of loading to start and protects that the driving band edge is not damaged is used to proofread and correct the device of band rail of the belt conveyor in the belt conveyor that returns and revising load border.
Traditional belt deviation rectifying device must be installed one every 10～15 meters on belt transporter; and belt autostable fender guard installation interval of the present utility model is 30～60 meters; like this; article one, the belt transporter that 50～75 groups of tradition deviation correcting devices are installed only need be installed 12～15 groups of the utility model devices, has saved productive costs greatly.The use of the utility model belt autostable fender guard; eliminated the friction of belt and support; prolonged the replacement cycle of common supporting-point roller, can improve the safety in production ability and the production efficiency of belt transporter greatly, made effective run duration of belt improve about 3 times.
Description of drawings
Fig. 1 is the structural representation of the utility model belt autostable fender guard.
Among the figure: 1. clad, 2. cylinder, 3. bearing, 4. sealing arrangement, 5. hollow, 6. in holder axle, 7. pivot.
The specific embodiment
The structure of belt autostable fender guard comprises cylinder 2, hollow 5 and middle holder axle 6 as shown in Figure 1.On the midperpendicalar of middle holder axle 6 axis, a rotating corrosion-resistant steel pivot 7 is installed, on the holder axle 6, leave enough gaps between the two, and the two ends of pivot 7 is fixedly connected on the hollow 5 during hollow 5 is enclosed within.The outside of hollow 5 is with cylinder 2, and between hollow 5 and cylinder 2 bearing 3 is installed, and the outside of bearing 3 is equipped with the labyrinth-type excluder 4 that prevents erosions such as dust.Outside face at cylinder is enclosed with the rubber of a softness or the clad 1 that the wear-resisting material of polyurethane is made, and the two edges of clad 1 and centre portion maintain 2 ° tapering.Said apparatus is fixed on the bearing set by the two ends of middle holder axle 6.
Owing on the axis of middle holder axle 6, rotary pivot 7 is installed, when belt deviation, utilize the special conical section in cylinder 2 two, can cause hinge 7 rotations of cylinder 2 around its center, thereby between belt and cylinder, produce the friction force of side direction, impel the belt recovery and remain on middle position.
