Abstract
The utility model relates to a novel friction-increasing driving roller which comprises a coating. Suckers which are passive vacuum suckers are arranged on the surface of the coating, and are distributed regularly on the surface of the coating; the suckers positioned on the same circumference are distributed equidistantly; and the suckers on the adjacent circumferences are arranged in a staggered way. The friction-increasing driving roller is regularly provided with the suckers on the surface; the inside air pressure and the outside air pressure of a conveyor belt for coating the suckers are different; and the friction between the roller and the conveyor belt is increased because the suckers has the absorption action on the conveyor belt, thereby improving the transportation capacity of a belt type conveyor.
Description
Technical field
The utility model relates to a kind of belt conveyer, particularly the drum segment of conveyer.
Background technology
Belt conveyer is modern most important bulk material handling equipment, is widely used in fields such as electric power, metallurgy, chemical industry, coal, mine and harbour, and the safety case of its operation and conveying efficiency are very big to the national economy influence.Belt conveyer is that to utilize tribology principle to realize mechanically operated, belong to flexible frictional transmission, flexible frictional transmission is subjected to the contact performance between friction pair, flexible member and the driver element and the influence of various factors such as characteristic of surface material, phenomenon such as transmitting ratio is non-constant appears skidding, wriggling easily.The belt conveyer of working under the many water conditions of humidity owing to skid between load-transfer device and head roll and deviation phenomenon often takes place, influences the normal operation of conveyer, causes difficulty to production.
Belt conveyer is to rely on the friction force between cylinder and the load-transfer device to drive the load-transfer device operation, and at present international and domestic increase friction force relatively more commonly used avoids the mode that cylinder and load-transfer device skid to have three kinds: the initial tension that 1, improves load-transfer device; 2, increase cylinder and enclose cornerite; 3, the friction coefficient between increase rolling and the load-transfer device.All there is drawback in these three kinds of methods, improve the initial tension of load-transfer device, must seek the high standard load-transfer device, and increase initial tension and can damage cylinder, shorten bearing life, and cause other problems such as belt body joint and load-transfer device fracture.Increasing predetermincd tension load-transfer device is increased at the tension force of driving drum separation point, though this method is feasible to improving tractive force, must select the load-transfer device of big section, cause the scantling of structure of driving device to strengthen like this, is uneconomic.Increase is enclosed cornerite and can be adopted methods such as twin-roll transmission, but the cost of twin-roll design raising equipment, and the increase of enclosing cornerite simultaneously is subjected to certain restriction.The drawback that the increase friction coefficient brings is the clad serious wear of driving drum, and the load-transfer device cal val is big, damage is very fast.
The utility model content
Cylinder and load-transfer device skidded easily when the utility model used at conveyer in the prior art, the all unfavorable defective of several settling modes that adopts, a kind of novel driving drum that rubs that increases is provided, the surface texture that this driving drum is special, can increase the friction force when contacting, improve the transport capacity of driving drum belt conveyer with load-transfer device.
The utility model at the technical solution that defective of the prior art adopts is:
A kind of novel driving drum that rubs that increases comprises: clad is provided with sucker in cover surface.
Above-mentioned sucker is passive vacuum cup.
Above-mentioned sucker has a plurality of, in the cover surface regular distribution.
Above-mentioned sucker is in the equidistant distribution on the same circumference, and the sucker dislocation on the adjacent circumferential is arranged.
Above-mentioned sucker is in the equidistant distribution on the same circumference, the sucker proper alignment on the adjacent circumferential.
Above-mentioned sucker is in the equidistant distribution on the same circumference, and the sucker proper alignment on the adjacent circumferential that has is arranged in the sucker dislocation on the adjacent circumferential that has.
The beneficial effects of the utility model: this kind increases the driving drum that rubs, rule of surface is provided with sucker, and the load-transfer device inner and outer air pressure difference of parcel sucker is because sucker is to the adsorption of load-transfer device, increase the friction force between cylinder and the load-transfer device, thereby improved the belt conveyer transport capacity.
Description of drawings
Fig. 1 is the novel structural representation that increases the driving drum clad that rubs;
Fig. 2 is the novel structural representation that increases the first kind of embodiment of driving drum that rub;
Fig. 3 is the novel structural representation that increases the second kind of embodiment of driving drum that rub.
Below in conjunction with accompanying drawing the utility model is elaborated:
The specific embodiment
Embodiment 1
In conjunction with Fig. 1, Fig. 2, a kind of novel driving drum that rubs that increases comprises: clad 1, be provided with sucker 2 on clad 1 surface, sucker 2 is passive vacuum cup, sucker 2 has a plurality of, distribute at clad 1 rule of surface, the sucker 2 that is on the same circumference equidistantly distributes, and sucker 2 dislocation on the adjacent circumferential are arranged.
During use, sucker 2 is squeezed, and the air in it is partly discharged, and load-transfer device and clad 1 are owing to the adsorption of sucker 2, and load-transfer device is attracted on the clad, has increased the friction force between cylinder and the load-transfer device, thereby improves the belt conveyer transport capacity.
In conjunction with Fig. 1, Fig. 3, a kind of novel driving drum that rubs that increases comprises: clad 1, be provided with sucker 2 on clad 1 surface, sucker 2 is passive vacuum cup, sucker 2 has a plurality of, distributes at clad 1 rule of surface, and the sucker 2 that is on the same circumference equidistantly distributes, sucker 2 proper alignment on the adjacent circumferential that has are arranged in sucker 2 dislocation on the adjacent circumferential that has.
During use, sucker 2 is squeezed, and the air in it is partly discharged, and load-transfer device and clad 1 are owing to the adsorption of sucker 2, and load-transfer device is attracted on the clad, has increased the friction force between cylinder and the load-transfer device, thereby improves the belt conveyer transport capacity.
Embodiment 3
Novel driving drum structure and embodiment 1, the 2 identical parts of rubbing that increase are not stated superfluous.Only be that the arrangement mode of sucker on clad is different, sucker has a plurality of, and in the cover surface regular distribution, the sucker that is on the same circumference equidistantly distributes, the sucker proper alignment on the adjacent circumferential.
