Description

Novel safety protection device for rubber belt conveyor

Technical Field

The utility model belongs to the technical field of safety protection, concretely relates to expansibility is good, high strength, easy dismouting, safe and reliable, but reuse's a novel safety device for band conveyer.

Background

The rubber belt conveyor is a material conveying machine which continuously conveys materials on a certain line by taking a conveying belt as a medium, and is also called a continuous material conveying machine, the conveyor can carry out horizontal, inclined and vertical conveying, and also can form a space conveying line, the conveying line is generally fixed, the conveying capacity of the conveyor is large, the conveying distance is long, and a plurality of process operations can be simultaneously completed in the conveying process. With the rapid development of economic level, the conveyor is widely used. At present, the groove type rubber belt conveyor is the most common, the rubber belt conveyor consists of an upper groove type carrier roller group and a lower flat carrier roller group, and in the using process, the conveying rubber belt naturally forms groove types with different sizes under the support of different types of groove type carrier rollers, so that materials are conveyed to the next procedure safely, stably and efficiently along the running direction in the conveying process. However, the conveying belt can run stably in the working process due to the fact that a large number of rollers and carrier rollers are required to rotate to drive, all rotating rollers, carrier rollers and conveying belts are completely exposed under the conditions of no protection and no shielding, pedestrian channels and operating platforms are arranged on two sides of the belt conveyor, and exposed rotating parts form great safety threats to post personnel, equipment point inspection personnel, maintenance personnel and related workers under the high-speed rotation. Meanwhile, the materials carried by the rubber belt conveyor drop carelessly in the operation process, and the rubber belt conveyor can be knocked to a safety pull rope switch of the rubber belt conveyor to cause halt, so that the normal operation of the next procedure is seriously influenced. In order to eliminate hidden dangers, reduce equipment operation risks and guarantee the personal safety of operators, protection is generally performed by a method of additionally arranging a safety protective guard on a rotating part of a rubber belt conveyor. According to the traditional method, maintainers directly install guard rails formed by welding and assembling steel pipes and wire netting on brackets at two sides of a rubber belt conveyor for protection, or directly locks the vestibule of the rubber belt conveyor to prevent people from entering the vestibule, not only directly influences the operation, the overhaul, the maintenance and the watch of the rubber belt conveyor, moreover, the traditional steel pipe and wire netting welding assembly protection is generally manufactured by the self-prepared welding of each using unit, the weight is heavy, the installation is difficult, the standardization is unqualified, the rust is easy, the maintenance is difficult, the structure is single, and the wire netting used has the defects of potential safety hazard to post operating personnel and the like, in the practice of a belt conveyor which usually has one person in charge of multiple or one long conveying distance, the detachment and installation of the guard rail at present are often difficult to implement by one person, and the equipment is more easily injured by people during operation.

Aiming at the defects of the prior protective guard of the belt conveyor, in the prior art, a base is fixedly arranged at the bottom end of the side of a conveying belt, then connecting rods extending downwards are arranged at the two sides of a protective plate to form independent guardrail units, the connecting rods at the two sides of each guardrail unit are sequentially inserted into the base to form a removable protective guard, and the guardrail units at the corresponding side are removed during maintenance; however, since only the bottom of the guardrail unit is stressed after being fixed, the center of gravity of the whole guardrail is higher, and the guardrail unit is easily inclined and inclined by external force in use, so that the stability of the guardrail unit is poor. In addition, vertical rods are arranged on the side of the conveying belt at intervals, triangular mortises and rectangular mortises on one side are arranged on the vertical rods at intervals, tenons are arranged at two ends of the protection plate correspondingly, and the protection plate is connected through a mortise joint structure to form the protection fence, so that the stability and the stability of the protection fence in actual use are ensured; but because the protection plate is connected for the horizontal direction with the mortise-tenon joint structure between the montant of both sides, just be difficult to take out the protection plate after the montant of both sides is fixed, overhaul, maintain the time just inconvenient at will, integral protection plate needs to be customized according to reality in addition, the commonality is poor and be difficult to standardized production, leads to the cost also higher and be difficult to reuse. Therefore, mortises are respectively arranged on two sides of the protection plate at intervals in the prior art, tenons are arranged on the vertical rods at intervals, and then the mortises of the protection plate are downwards aligned with the tenons to be inserted for mortise and tenon connection to form the protection guard when the protection plate is used, so that the protection plate can be conveniently dismounted and mounted as required, and the defects that the protection plate is of an integral structure exist. Therefore, it is necessary to research a safety protection device for a belt conveyor to solve the problems of potential safety hazards during the operation of the belt conveyor and inconvenience in daily maintenance and repair.
