Narrow-machine-body full-hydraulic bolt and anchor cable drill carriage for coal mine tunnel

Abstract

The invention relates to a narrow-machine-body full-hydraulic bolt and anchor cable drill carriage for a coal mine tunnel. The narrow-machine-body full-hydraulic bolt and anchor cable drill carriage comprises a machine body part, a lifting platform, a drill boom mechanism, crawler-type walking mechanisms and an electric cabinet, wherein the lifting platform is arranged at the machine body part through a foldable connecting rod and a lifting oil cylinder; the drill boom mechanism is arranged on the lifting platform through a feeding mechanism; the crawler-type walking mechanisms are arranged on two sides of the machine body part; and the electric cabinet is used for controlling the lifting oil cylinder and the crawler-type walking mechanisms. According to the narrow-machine-body full-hydraulic bolt and anchor cable drill carriage disclosed by the invention, the support of an anchor rod is completely mechanized, the support efficiency and the support quality of the bolt and anchor cable are greatly improved, the standardization degree is improved, the better stabilizing action is realized and the reliable use of the drill carriage and the safe operation of operators are fully ensured.

Description

technical field [0001] The invention relates to the technical field of mining mechanization equipment, in particular to a narrow-body full-hydraulic bolt and cable drilling vehicle for coal mine roadways. Background technique [0002] In the 1960s, bolt and cable support began to be applied in mining roadways in my country, but the materials, equipment and detection methods were not perfect enough. At present, there are more than 2 million meters of roadways supported by anchor bolts, cables and shotcrete in state-owned large and medium-sized coal mines. However, the overall mechanized equipment level of the roadway excavation face is relatively backward, especially the bolt support operation. At present, most coal mine roadways are fully mechanized excavation working faces, and the support methods such as bolt and cable support equipment and appliances in the roadway are quite backward. Simple machines (hand-held single drilling rigs) are basically used for bolt and cable s...

Problems solved by technology

[0002] In the 1960s, bolt and cable support began to be applied in mining roadways in my country, but the materials, equipment and detection methods were not perfect enough.

At present, most coal mine roadways are fully mechanized excavation working faces, and the support methods such as bolt and cable support equipment and appliances in the roadway are quite backward. Simple machines (hand-held single drilling rigs) are basically used for bolt and cable support operations, mainly relying on Carrying people on their shoulders to carry out support work under the head-on empty roof and under the empty side, this operation method has problems such as low production efficiency, high labor intensity for workers, and high hidden dangers of unsafe construction for workers

In a small number of excavation working faces with good geological conditions and large design roadway sections, continuous miners and four-arm drilling vehicles are used for double-way tunneling or single-way tunneling is used for single-way tunneling with an integrated machine for digging and bolting. However, the supporting equipment used Large in size and heavy in weight, it is extremely unsuitable for use in fully mechanized excavation working faces

[0003] It can be seen that the support equipment used in the prior art has obvious defects and deficiencies in the use of the fully mechanized excavation face. Therefore, how to create a fully mechanized excavation It is one of the current important research and development topics to use the narrow fuselage bolt and cable drilling rig that can be used in the working face and can fully mechanize the roof bolt, cable and side wall bolts.
