Abstract
The utility model discloses rubber belt joint structure of a belt conveyor. The rubber belt joint structure comprises a rubber belt (3) which is placed on a rack when the lapping allowance of two joints is smaller than the joint bonding size or approaches zero, wherein a pocket-sized joint (2) used for connecting the two rubber belt joints is arranged between the two joints of the rubber belt (3), adopts a stepped shape, and is ingradient connection with the rubber belt joints in a rubber belt operation direction (1); and the length of the pocket-sized joint (2) is not larger than the effective vulcanization size of a heating plate of a vulcanizer. When the lapping allowance of the two joints is smaller than the joint bonding size or approaches zero, the pocket-size joint is used for vulcanizing repair at the rubber belt joints, various defects of the traditional rubber belt joint inspection and repair technology are overcome, the service life of the rubber belt is prolonged effectively, the inspection and repair costs are saved greatly, and substantial economic benefits are created; and the technologyby using the pocket-size joint for vulcanizing repair of the rubber belt joints is the same with a vulcanization technology during rubber belt manufacture, meanwhile, the vulcanizergives a full play to the maximum function, the inspection and repair quality is improved, and the production safety is enhanced.
Description
Technical field
The utility model belongs to belt of belt conveyer joint connection area, is specially a kind of belt of belt conveyer joint structure.
Background technique
Rubber conveyer as coal chemical enterprise for industrial and mineral field significant transportation equipment such as coal measures system, coal, mine, harbours, adhesive tape is one of chief component of Belt Conveyors, it is through conveyor total length, consumption is maximum, price is more expensive again, accounts for 50% left and right in the cost of Belt Conveyors.Before new adhesive tape puts into operation, in order to guarantee tension force, the frictional force between belt and driving drum, a joint maintenance surplus is only considered in normal tape splice docking.New adhesive tape put into operation after a period of time, tape splice there will be peeling, natural aging, the phenomenons such as gap appear in the aliquation that comes unglued, two joint joints, cause joint tensile strength obviously to reduce, for guaranteeing rubber conveyer safe and stable operation, need block tape splice according to the rubber conveyer repair cycle, again make a joint.When tape splice keeps in repair for the second time, when being less than the bonding size of joint or two joints overlap joint surpluses and approaching zero due to two joints overlap joint surpluses, traditional maintenance craft takes to change whole piece belt, one section of new adhesive tape of local replacing is repaired tape splice.
While changing the new belt of whole piece if take, often occur that remaining part is better except tape splice serious wear, therefore cause repair materials to waste and add the labor intensity of general overhaul.When taking to change one section of belt, need bonding two belt lacings, because adhesive tape is in service, contacts with the affiliated facility tight friction such as carrying roller, sweeper, cylinder, belt plow and impact, joint natural aging on the other hand, aliquation comes unglued, often cause belt lacings to damage, therefore more adhesive tapes of joint rate of fault is higher, simultaneously maintenance workload and also corresponding increase of recondition expense; When taking mechanical connection, mechanical connection method couples together belt by metal clamps or metal rivet exactly.The belt intensity that this method couples together is lower, and its join strength is only equivalent to 35%～40% of the own intensity of rubber conveyor belt conventionally, and the belt after connection is short working life, easily has an accident.
Therefore, for extending belt work life, reduce maintenance workload, saving recondition expense, when two joints overlap joint surpluses of adhesive tape are less than, when the bonding size of joint or two joints overlap joint surpluses approach zero, to provide a kind of adhesive tape conveyer tape splice structure and attaching method thereof be a good problem to study.
Summary of the invention
