Six-arm full hydraulic anchor rod and anchor cable drill carriage used in cooperation with continuous miner

Abstract

The invention provides a six-arm full hydraulic anchor rod and anchor cable drill carriage used in cooperation with a continuous miner. The six-arm full hydraulic anchor rod and anchor cable drill carriage is mainly composed of a walking mechanism, a lifting mechanism, a temporarily supporting mechanism, drilling arm mechanisms, an electrical system and a hydraulic system. A drilling mechanism is installed at the front end of each drilling arm mechanism, and the lifting mechanism comprises an installing platform and a lifting platform. The installing platform is arranged on the upper portion of the walking mechanism, the temporarily supporting mechanism is fixed to the lifting platform, and the number of the drilling arm mechanisms is six. The four drilling arm mechanisms are arranged at the front of the drill carriage, and the two drilling arm mechanisms are arranged at the rear of the drill carriage. The four drilling arm mechanisms at the front are arranged in a line shape and installed on a slide rail through a first rotating oil cylinder, the slide rail is installed on the lifting platform through a second rotating oil cylinder, and the two drilling arm mechanisms at the rear are installed on the installing platform. Full fracture surface anchor rod and anchor cable supporting work on a continuous mining working surface can be finished in a one-off mode, and therefore working efficiency is improved.

Description

technical field [0001] The invention relates to the field of rock bolt drilling rigs, in particular to a six-arm fully hydraulic rock bolt and cable drilling rig used in conjunction with a continuous coal mining machine. Background technique [0002] China's energy reserves are "lack of oil, less gas, and rich in coal", so coal has long accounted for more than 70% of China's primary energy consumption. With the rapid growth of China's economy, coal consumption has also continued to increase. In 2013, coal production reached 3.7 billion tons. It is expected that the growth rate of coal consumption will remain at about 3% in the coming period. By 2020, the total national coal demand It will be around 4.8 billion tons. By then, the proportion of coal in my country's primary energy consumption structure will still account for about 60%. By 2020, the country's available coal production capacity will be 4 billion tons, with a production capacity gap of about 800 million tons. [...
