Abstract

The utility model relates to a loading friction adjustment supporting roller assembly for the belt conveyor. Through improvement of the supporting roller assembly for the present belt conveyor, the device provides a loading friction adjustment supporting roller assembly that is applicable for the conveyor belt with a width of 1600mm, 1800mm or 2000mm.The assembly is characterized in that the lower part of the upper crossbeam corresponding to the two friction supporting rollers are respectively provide with a balance adjusting mechanism; the upper end of the bearing board of the balance adjusting mechanism is connected to the upper crossbeam; the lower end of the bearing board is connected with an adjustable balance wheel that is located on the upper plane of the horizontal bearing bracket and the lower part of the horizontal bearing bracket is fixed on the lower crossbeam. The maximal adjusting angle is more or less than 16 degree. The materials that cannot be stacked in the mid on the conveyor belt can be adjusted to the state of being evenly pressed through the balance mechanism without affecting the normal operation of the supporting roller assembly. Meanwhile, the deviation of the belt can be easily corrected, thereby avoiding the chucking of the adjustment device.

Description

The deviation regulating idler group is gone up in the heavy duty friction of belt conveyer automatically

Technical field

The utility model relates to the carrying roller group of belt conveyer.

Background technology

In order to adapt to each big colliery, the harbour, electric power, the production of building materials and Chemical Manufacture enterprise needs, in recent years, belt conveyer manufacturer has designed width voluntarily and has surpassed 1.5 meters big specification, the belt conveyer of large conveying quantity, but, the aligning carrier roller group comprises two friction carrying rollers in the friction of existing belt conveyer, middle idler roller, entablatrance and cross sill, two frictions carrying roller and middle idler rollers are positioned at entablatrance top, on, the middle part is an automatic aligning mechanism between the cross sill, can only satisfy width 500-1400 belt conveyer uses, in the operational process of large conveying quantity, because the difference of installation environment, the phenomenon that device load-bearing capability is excessive causes belt deflection easily; Because material can not be piled up all the time between two parties; be easy to cause the aligning axle stuck because of unbalance loading, the effect of automatic aligning just can't be played in stuck back, even can cause load-transfer device sideslip seriously; heavy then tear to pieces load-transfer device, light then fender guard by belt conveyer causes shutdown.

Summary of the invention

The purpose of this utility model is: by the improvement to existing belt conveyer carrying roller group, provide a kind of heavy duty friction that is suitable for the belt conveyer of big specification, large conveying quantity to go up the deviation regulating idler group automatically.

Concrete structural design scheme is as follows:

The heavy duty of belt conveyer friction is gone up the deviation regulating idler group automatically and is comprised two friction carrying rollers, middle idler roller, entablatrance and cross sills, and two friction carrying rollers and middle idler roller are positioned at entablatrance top, and the middle part is an automatic aligning mechanism between the upper and lower crossbeam.

Be connected back plate respectively with two the cooresponding entablatrance of friction carrying roller bottoms, the back plate lower end is provided with adjustable balance wheel by horizontal wheel shaft, and adjustable balance wheel is positioned at the last plane of Horizontal Branch bolster, and Horizontal Branch bolster bottom is fixed on the cross sill.

Upwards curved with both sides, plane on the cooresponding Horizontal Branch bolster of adjustable balance wheel moving direction.

Useful technique effect of the present utility model is embodied in following several aspect:

1, the utility model has solved the difficult problem of big specification, large conveying quantity belt conveyer tuningout and correction.

2, the maximum of the utility model carrying roller group carrying traffic capacity can reach 11277 tons/hour, is applicable to that the load-transfer device width is the belt conveyer of 1600 millimeters, 1800 millimeters and 2000 millimeters.

3, the heavy duty of belt conveyer friction is gone up the deviation regulating idler group automatically because of having set up the adjusting deviation device of both sides, maximum tuningout angle is ± 16 degree, even material can not be piled up between two parties in the use, also can transfer to uniform-compression, and correct rubber belt from deviating like a cork, avoided the generation of aligning device stuck phenomenon.
