A four-arm fully hydraulic bolt and cable drilling rig

Abstract

The invention relates to a fully-hydraulic four-arm anchor rod / anchor cable drill carriage. The fully-hydraulic four-arm anchor rod / anchor cable drill carriage comprises a traveling mechanism, drilling mechanisms, a lifting mechanism, a drill arm mechanism, a temporary supporting mechanism, a pump station part, an electrical system and a hydraulic system, wherein the electrical system is connected with the pump station part and is used for controlling the pump station part; the hydraulic system comprises an oil tank and a hydraulic pipeline; the hydraulic pipeline is used for connecting the oil tank, the pump station part and each execution mechanism; the traveling mechanism is positioned at the bottom of the drill carriage; an installation platform is arranged on the upper part of the traveling mechanism; the oil tank, the pump station part and the electrical system are fixed on the installation platform; the lifting mechanism comprises a front lifting platform and a rear lifting platform, which can independently lift; the drill arm mechanism comprises two front drill arms and two rear drill arms, which are respectively arranged on the front lifting platform and the rear lifting platform; the top end of each drill arm is provided with a drilling mechanism; the temporary supporting mechanism is arranged on the front lifting platform and / or the rear lifting platform. By virtue of the fully-hydraulic four-arm anchor rod / anchor cable drill carriage provided by the invention, the supporting operation of a working face of a tunneling machine can be mechanized, supporting efficiency and operation safety coefficients are improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of rock bolt drilling rigs, in particular to a four-arm fully hydraulic rock bolt and cable drilling rig. 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 2011, coal production reached 3.52 billion tons, and in 2012, coal production reached 3.7 billion tons. It is expected that the annual output will exceed 4 billion tons by the end of the "12th Five-Year Plan". [0003] With the development of science and technology in the coal industry and the requirements of my country's industrial policy, since the 1980s, advanced bolt and cable support technology has been widely used in coal mine roadway excavation in my country. At present, most of the bolt and cable support operations in large and med...
