Transshipment anchor rod and anchor cable drill carriage

Abstract

The invention discloses a transshipment anchor rod and anchor cable drill carriage which comprises a self-walking mechanism, a transshipment mechanism and a support mechanism. The self-walking mechanism is located at the bottom of the drill carriage, and an installation platform is arranged on the upper portion of the self-walking mechanism. The transshipment mechanism comprises a hopper and a transportation chute. The support mechanism comprises an anchor rod and anchor cable ejection drill rig, a slide for installation of the anchor rod and anchor cable ejection drill rig, an anchor rod and anchor cable assisting drill rig and a drill boom mechanism. The slide is installed on the installation platform in the direction perpendicular to the axial direction of the drill carriage and can stretch and draw back horizontally, and the anchor rod and anchor cable ejection drill rig can slide on the slide. The bottom end of the drill boom mechanism is installed on the installation platform, and the anchor rod and anchor cable assisting drill rig is installed at the top end of the drill boom mechanism. The support mechanism can conduct unfolding, contracting and supporting operations under the effect of an electric and hydraulic system. The transshipment anchor rod and anchor cable drill carriage integrates functions of material transshipment, material crushing and anchor rod and anchor cable supporting, achieves mechanical associated operating of the digging and anchoring work surface, conducts digging and anchoring simultaneously, and therefore greatly improves the digging efficiency and the digging footage and effectively solve the contradiction of digging imbalance.

Description

technical field [0001] The invention relates to the field of bolter drilling rigs used for supporting operations in underground coal mines, in particular to a transfer, bolter and cable bolter drilling rig integrating the functions of transfer, crushing, and bolt and cable support. Background technique [0002] my country's coal mines are out of balance, and the backwardness of the tunneling is relatively serious, which has become a "bottleneck" restricting the development of coal production. In the roadway tunneling operation, the operating rate of the roadheader is only about 30%, and most of the rest of the time is used for support. Low support efficiency is the most important factor affecting the excavation footage. [0003] With the development of science and technology in the coal industry and the requirements of my country's industrial policy, relatively advanced tunneling equipment with bolt support functions, such as bolting machines, have been introduced into coal m...

Problems solved by technology

[0002] my country's coal mines are out of balance, and the backwardness of the tunneling is relatively serious, which has become a "bottleneck" restricting the development of coal production. In the roadway tunneling operation, the operating rate of the roadheader is only about 30%, and most of the rest of the time is used for support. Low support efficiency is the most important factor affecting the excavation footage

[0003] With the development of science and technology in the coal industry and the requirements of my country's industrial policy, relatively advanced tunneling equipment with bolt support functions, such as bolting machines, have been introduced into coal mine roadway excavation in my country, but usually only part of the bolt jacking is carried out. Anchor cable support and side bolt support, the remaining large amount of top bolt anchor cable support and part (or all) side bolt support are all completed by workers with hand-held bolters, not only because the hand-held bolter It is a manual operation, and the limitation of manpower itself causes the locking force of the bolt to be tightened twice, which not only increases the workload, is time-consuming and laborious, but also requires workers to work in groups, and the degree of mechanization is low, the labor intensity is high, and the working environment is harsh. poor security

Therefore, the existing equipment with bolt support function cannot meet the requirements of higher support efficiency due to its own structure and functional scope, and cannot fundamentally solve the contradiction of mining imbalance in the coal industry

[0004] This shows that the above-mentioned existing equipment with bolt support function obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently
