Automatic loading and unloading platform for drill rod group

Abstract

The invention discloses an automatic loading and unloading platform for a drill rod group. The automatic loading and unloading platform comprises a bottom plate, a sliding table, a side sliding driving device and a drill rod group positioning component, the sliding table is slidably connected to the bottom plate by single degree of freedom and is driven by the side sliding driving device to slide in a reciprocating manner, the drill rod group positioning component is mounted on the sliding table, drill rods and air ducts are combined to form the drill rod group which can be conveyed to the space between a spindle of a spiral drill type coal mining machine and a connected drill rod group through the sliding table after the drill rod group is placed and positioned on the automatic loading and unloading platform for the drill rod group, a main engine is controlled to advance, so that the drill rod group can be connected, the sliding table can return to an original position after connection, a next drill rod group is mounted, the drill rod group can be detached by the aid of reverse execution, manual loading and unloading can be replaced, the labor intensity of workers is reduced, the drill rod group can be accurately positioned, the drill rods are successfully loaded and unloaded, time consumption is reduced, and the mining efficiency of coal beds is improved.

Description

technical field [0001] The invention relates to a drilling rod assembly and unloading device for an auger coal shearer, in particular to an automatic loading and unloading platform for a drilling rod. Background technique [0002] my country is a country with large coal production and consumption. With economic growth, the demand for coal is also rising. According to the division of coal seam thickness in my country, the thickness of 18 ~ 113m belongs to thin coal seam, and the thickness of less than 18m belongs to extremely thin coal seam. The reserves of thin and extremely thin coal seams are large in my country, and the proportion of thin coal seam reserves in state-owned coal mines alone accounts for about 20%. Large, widely distributed, and locally concentrated. With the decreasing reserves of medium-thick coal seams, the mining of thin and extremely thin coal seams is particularly important. The efficiency is low, so the dependence on mining equipment and technology is ...

According to the division of coal seam thickness in my country, the thickness of 18 ~ 113m belongs to thin coal seam, and the thickness of less than 18m belongs to extremely thin coal seam. The reserves of thin and extremely thin coal seams are large in my country, and the proportion of thin coal seam reserves in state-owned coal mines alone accounts for about 20%. Large, widely distributed, and locally concentrated. With the decreasing reserves of medium-thick coal seams, the mining of thin and extremely thin coal seams is particularly important. Low efficiency and therefore greater reliance on mining equipment and technology

The auger shearer is a coal mining equipment that can mine thin and extremely thin coal seams and improve the recovery rate of coal resources. It can realize unmanned working face mining and improve the working environment of workers. Shearers generally use monorail crane clamping and manual positioning to load and unload drill pipes, which not only has a high labor intensity for workers and difficult positioning of drill pipes, but also greatly limits coal mining efficiency, resulting in slow mining of thin and extremely thin coal seams. The problem of low internal production
