Problems solved by technology
There is a large demand for single pillars in roadway support, but at present, the transportation of single pillars underground is mostly dragged and carried by coal miners; especially as the working face advances, the single pillars in the advance support section of the roadway need to be withdrawn at any time and transported to the required location. The support position causes the coal miners to have high labor intensity and extremely low work efficiency, which is not conducive to the physical and mental health of the coal miners, and also affects the advancing speed of the working face

Embodiment Construction
[0020] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0021] like figure 1 As shown, the rapid transfer device for single pillars in the advance support section of the coal mining face of the coal mine of the present invention includes multiple single pillars 2 arranged in rows in the roadway, and the multiple single pillars 2 arranged in rows A hoop piece 1 is provided, and the hoop piece 1 is installed on the single pillar 2 through a bolt 3, which is convenient for installation and disassembly. The hoop piece 1 on each single pillar 2 is provided with a sliding passage 4, and the sliding passage 4 There are one or more sliding devices 6 that move in the track of the sliding channel 4 , and a conveyor is arranged below the sliding device 6 , and the conveyor is a hook or a hanging basket connected by a hanging chain 5 .
[0022] like figure 2 As shown, the sliding channel 4 is composed of a plurality of s...

The invention discloses a coal mine coalface advance support section single supporting column rapid moving-arrangement device and method which are suitable for being used in a coal mine downhole roadway supported by single supporting columns in a downhole. Sliding channels and embracing hoop pieces are welded to be a whole and fixed on the row of single supporting columns through the embracing hoop pieces. The single supporting columns needing to be transported are conveyed to a supporting position through hanging chains, hooks and a sliding device. With advancing of a coalface, the sliding channels are utilized circularly by detaching and mounting the embracing hoop pieces. The device is simple in structure and convenient to use. Compared with a manual detaching mode, the labor intensity of workers is relieved greatly, the working efficiency is improved significantly, and the single supporting columns are carried rapidly and safely.
Description
technical field [0001] The invention relates to a device and method for quick transfer of a single pillar, and is especially suitable for the device and method for quick transfer of a single pillar used in coal mine coal mining face advance support sections in underground coal mines. Background technique [0002] In the environment of accelerated global industrialization, coal resources are still one of the important energy sources in my country. my country's coal resources have the characteristics of wide distribution and complex storage conditions. During the mining practice, they often encounter situations such as suspended roofs, faults, and inclinations, which lead to frequent roof fall accidents, making coal mine support equipment an important safety guarantee. The single hydraulic prop is used for the support of the roof working face, the advance support of the roadway and the temporary support. The single hydraulic prop has the characteristics of large initial suppor...
