Rotary type high-capacity drill pipe cabin for coal mine

Abstract

The invention belongs to the technical field of anchorage cable holding devices, and particularly discloses a rotary type high-capacity drill pipe cabin for a coal mine. The problems of high labor intensity of workers, low production efficiency, poor operating environment and low safety factor in existing underground coal mine drilling pipe operation are solved. The rotary type high-capacity drillpipe cabin comprises a main machine frame, the main body frame is internally provided with a rotary table mechanism used for storing drill pipes, the main machine frame is provided with a manipulatorused for taking out the drill pipes rotating to a work position, the manipulator is fixed to a rotating mechanism, the rotary table mechanism is driven by a ratchet mechanism with intermittent motionindexing in one direction, and the rotary table mechanism is provided with an anti-reverse-rotation mechanism to prevent reverse rotation. The rotary type high-capacity drill pipe cabin realizes a large amount of storage, accurate positioning and accurate compensation of drilling pipes for underground anchorage cable holding operation in the coal mine; and the rotary type high-capacity drill pipecabin is applied to anchorage cable holding systems to realize the functions such as remote operation, automatic pipe connecting and drilling and automatic recovery of the drilling pipes, has high adaptability, improves the degree of automation of underground anchor cable operation, and reduces the labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of anchor cable support equipment, in particular to a rotary large-capacity drill pipe bin for coal mines. Background technique [0002] The theory and technology of roadway support has always been one of the core research contents of coal mine rock formation control. At present, the roadway support pattern in my country is mainly based on bolt and anchor cable support, and multiple support methods coexist. Compared with bolt support, anchor cable support has the advantages of large anchorage depth, strong bearing capacity, and large prestress. my country began to use anchor cable support technology in the 1960s, and in the 1990s in coal mine roadways. widely used in nursing. Due to the large drilling depth required for anchor cable support, multiple wet drill pipes are generally connected in sequence to drill holes in China. After the drilling process is completed, the drill pipes are removed one by one. Ge...
