Description

Tail tensioning structure of belt conveyor

Technical Field

The utility model relates to a belt conveyor afterbody tensioning texture is applicable to the transport technical field of likepowder, graininess and the bulk material of fritter.

Background

The working process of the general belt conveyor is as follows: the materials enter the conveying belt which forms a certain radian through the feeding hole, and the power system drives the conveying belt to move so as to drive the materials to be conveyed. When the materials reach the head roller, the conveying belt is flattened and changes direction, the materials in the conveying belt are thrown out, and discharging is finished.

Because the conveyer belt has the extensibility, the conveyer belt tensioning structure is indispensable in the structural composition of the belt conveyor. The tensioning structure is generally arranged at the tail part at a short distance (generally less than 60 meters), and the tail part is called tensioning. Generally, a screw tensioning structure is adopted.

The problems with the above structure are:

1) the belt cannot be sensed to extend automatically, and the belt cannot be tensioned automatically. The belt extension needs to be confirmed by matching with other induction systems, and after the system gives an alarm, the tension needs to be manually adjusted. The tensioning requires highly, easily leads to the belt feeder off tracking problem.

2) When the equipment works or stops, the belt is always in a tensioning state, and the extension of the belt is accelerated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of above-mentioned prior art, provide a belt conveyor afterbody tensioning texture to solve the problem of the automatic tensioning of conveyer belt.

The technical scheme of the utility model as follows:

the tail tensioning structure of the belt conveyor is characterized by comprising a supporting frame and two hydraulic cylinders, wherein the conveyor tail is arranged in the supporting frame, and two side surfaces of the supporting frame are respectively provided with a pair of horizontally arranged cross beams which are parallel to each other; two ends of a rotating shaft of the conveyor tail roller respectively penetrate through a tail shell and are arranged between a pair of corresponding cross beams through bearings, and strip-shaped sliding grooves for the horizontal displacement of the rotating shaft are respectively formed in two side walls of the tail shell; the end of the tail roller is respectively provided with a hydraulic cylinder, the hydraulic cylinders are horizontally arranged between a pair of cross beams, and the telescopic ends of the hydraulic cylinders are connected with the outer bearing seats at the ends of the rollers; the two hydraulic cylinders respectively support the bearings at the two ends of the rotating shaft, so that the conveying belt is in a tensioning state.

Preferably, the telescopic end of the hydraulic cylinder is connected with the bearing outer seat at the corresponding position through a connecting piece, and the upper end and the lower end of the connecting piece are respectively provided with a clamping groove for being in sliding connection with the pair of cross beams.

Preferably, the clamping groove is of a U-shaped structure, so that the corresponding beam can be conveniently placed and slide.

Preferably, the rear part of the hydraulic cylinder is hinged to the support frame.

The utility model is suitable for an all belt conveyors, before equipment is opened, start hydraulic system, pneumatic cylinder work, its flexible end drive connecting piece, the connecting piece slides between two crossbeams through its draw-in groove, and the connecting piece front end orders about the bearing outer housing antedisplacement that corresponds, drives the cylinder pivot forward slip in the bar spout then, realizes the conveyer belt tensioning. After the conveying belt extends, the hydraulic cylinder automatically compensates the extension stroke, so that the conveying belt is always in a tensioning state, and the normal work of the belt conveyor is ensured. The length of the strip-shaped sliding grooves on the two sides of the tail shell determines the tensioning stroke of the conveying belt. After the equipment is shut down, the hydraulic system stops working, the hydraulic cylinder is recovered, the conveying belt is loosened, and forced extension in a non-working state is avoided.

The utility model has the advantages as follows:

1) automatic tensioning of the equipment is realized;

2) the relaxation is reasonable, and the service life of the conveying belt is prolonged.
