Slope Conveyor Belt To Ensure Safe Production
May 10, 2017

Slope Slope Conveyor Belt is one of the most important transportation equipment in the coal mining industry. The Slope Conveyor Belt is an important part of the belt conveyor. The Slope Conveyor Belt runs through the whole length of the conveyor (2 times of the fuselage). It is the traction mechanism , But also the bearing mechanism, the quality of the Slope Conveyor Belt is good or bad, the performance of the belt conveyor a great impact, in addition, the Slope Conveyor Belt price is also very expensive, accounting for about 50% of the total conveyor costs to 70%. There are 30 belt conveyors in the Daping Coal Mine. The length of the Slope Conveyor Belt is about 10 000 m, accounting for 80% of the transportation equipment. The statistics of the last 10 years show that the cost of the Slope Conveyor Belt is dominated by the maintenance cost of the belt conveyor It is an important measure to improve the life of the conveyor and reduce the transportation cost. The practice shows that the replacement of the Slope Conveyor Belt in transportation is mostly due to the transportation of the Slope Conveyor Belt. With the damage caused by a reasonable decision and try to extend the service life of the Slope Conveyor Belt, to ensure safe production, reduce transportation costs have important practical significance.

1 Slope Conveyor Belt damage causes

(1) the transfer machine and belt conveyor tail lap height is not enough, or the tail buffer roller loss of elasticity, large pieces of material from the loader to fall, the formation of a greater impact and hit the Slope Conveyor Belt on the cover , And even broken with the core, the formation of holes. Especially when the material entrainment of sharp objects, such as scraper, etc., it is easy to cut the Slope Conveyor Belt, causing the Slope Conveyor Belt longitudinal tear.

(2) with edge wear. The main reason is due to tape deviation, causing the tape and the rack friction, resulting in pulling with the edge of the hair. Belt with the most vulnerable to damage, because it is small, not wearable. With the edge of the wear and tear, the water from the damaged Department of immersion, the course of time, canvas layer will gradually rot.

(3) Slope Conveyor Belt lap does not meet the requirements. Such as missing joints, uneven is not straight, resulting in uneven transmission of the belt and rupture.

(4) Slope Conveyor Belt manufacturing quality is poor or improper use. Such as the use of the surface of the tape, the summer long-term exposure in the hot sun, winter tape surface water ice caused by tape quality hardening early aging. In addition, the use of the tape due to excessive tension or tape laying distance is too short, the number of deflection over the limit, but also easy to damage the tape early aging.

2 repair of Slope Conveyor Belt

2.1 Adhesive bonding

This method is suitable for damage to the Slope Conveyor Belt protective layer, the area is small, with the core layer damage lighter. The specific steps are:

(1) Carefully observe the degree of damage to the Slope Conveyor Belt and determine the shape, extent and size of the repair.

(2) with a knife to determine the scope of the cover to cover and tear off.

(3) with a grinding wheel or wood file to be polished surface, so that it has a certain degree of roughness.

(4) with a brush will be equipped with a good adhesive evenly coated in the tape grinding, air drying about 20 min.

(5) Place the overlay stick with the shape of the repair, place it in a sticky position, and then beat it evenly with a wooden hammer until it is tightly adhered.

2.2 cracks solid strong

Slope Conveyor Belt cracks are usually two kinds: (1) obvious. (2) invisible. The obvious cracks are easily found, and the length and depth of the cracks can be directly observed or measured. While the invisible cracks refer to the integrity of the watch and the canvas core has been broken damage, the cracks are often poor quality or the use of long Slope Conveyor Belt appears. Invisible cracks are not easy to identify, carefully observed in order to find the plastic surface concave and small cracks.
