Description

Double-clamp brick holding machine Technical Field The utility model relates to the technical field of storage devices, in particular to a storage device for safety inspection tools of mining equipment. Background At present, most of mature brick holding machines on the market are single-clamp brick holding machines matched with brick kilns, such as a small mantis brick holding device disclosed in Chinese patent No. CN202120166659.X, and the brick holding machines are mainly used for holding, moving and discharging formed green bricks stacked in piles in the production and processing of bricks for buildings. The brick for building materials has the characteristic of high strength, and the single-clamp brick holding machine has excellent clamping effect on the brick for building materials, but has poor effect on clamping low-strength and low-plasticity baked bricks such as vanadium ores, lithium ores and the like. After brick piles formed by pressing bricks with stone coal vanadium ores as raw materials are oxidized and roasted by a tunnel kiln, the intensity of green bricks is lower, and the conditions of crushed aggregates, brick leakage and the like exist when a single-clamp brick holding machine is adopted for discharging, so that a large amount of crushed bricks remain on the kiln car surface of the tunnel kiln, the discharging efficiency is reduced, the labor intensity is increased, and the problems of poor working environment, large dust and the like exist.
