A retractable conveyor tape system for rock semi-continuous mining process

Abstract

The invention discloses a telescopic transporting rubber belt system for a rock semi-continuous mining process. The telescopic transporting rubber belt system comprises a transporting rubber belt (1) and a rubber belt protecting device, wherein the protecting device comprises a rail (2), an arc-shaped baffle plate (3), rolling wheels (4) and a driving motor (6); the rail (2) is arranged at one side, near a blasting position, of the transporting rubber belt (1), the arc-shaped baffle plate (3) is used for protecting the transporting rubber belt (1) from being damaged by flying stones; the rolling wheels (4) are used for the moving of the arc-shaped baffle plate (3), the driving motor (6) is used for driving the rolling wheels (4) to roll; the arc-shaped baffle plate (3) is movably connected with the rail (2) through the rolling wheels (4); and an output shaft of the driving motor (6) is connected with the rolling wheels (4). The movable arc-shaped baffle plate is arranged at one side, near the blasting position, of the transporting rubber belt (1); the position of the arc-shaped baffle plate can be freely moved according to blasting and mining requirements; during the blasting, the arc-shaped baffle plate is moved to the blasting position for preventing the flying stones generated during blasting from damaging the transporting rubber belt; and after the blasting is completed, the arc-shaped baffle plate is moved away, and the influence on the normal mining operation by the arc-shaped baffle plate is avoided.

Description

technical field [0001] The invention relates to a retractable transport tape system for a rock semi-continuous mining process, which belongs to the technical field of protection devices. Background technique [0002] With the continuous innovation of open-pit mining technology, large-scale open-pit mines have gradually transitioned from traditional intermittent processes to semi-continuous and continuous processes, and the belt system plays an increasingly important role in transportation. In addition to transporting coal, the belt also undertakes some rock stripping operations. However, in the rock semi-continuous process system, the location of the tape laying is close to the blasting operation area, which is often affected by flying rocks, resulting in a reduction in the life of the tape and an increase in equipment failure rate, which further leads to low production efficiency and increased costs. The traditional fixed tape protective canopy can protect the tape very we...
