Description
Technical field
The present invention relates to coal mine machinery field, especially relate to a kind of hydraulic support, especially for the mechanical coal mining equipment of fully-mechanized mining working two ends roof timbering and otch excavation.
Background technology
At coal mine fully-mechanized mining working, the handpiece of scraper conveyer groove that is positioned at work plane two ends need to be higher than intermediate channel, to install motor and reducer, and can on the equipment transporting in lane, unload coal smoothly; Again because some coal-winning machines adopts the asymmetric layout of rocking arm and termination rocking arm, and other structural limitations (the haulage chain tensioning apparatus if any chain hauled shearer has equivalent length), coal mining machine roller is difficult to cut to the rib at work plane two ends.The rib that this part of coal-winning machine cannot be adopted, need to adopt in advance, and work plane could normally advance, and makes coal mining activity successive.Here it is at work plane two ends excavation otch.
In order to shorten incision length, Scraper Conveyor in Mining Face can adopt short head groove or short head groove, by on the chute of rib side, motor and reducer be not installed, or motor and reducer are vertically mounted on chute, the conveyer head groove of 90-degree bent is located in tunnel, can expand to greatest extent the traveled distance of coal-winning machine.Rocking arm is arranged in the side at fuselage two ends and has suitable length, also can make the cut scope of cylinder expand as far as possible.But even cylinder can reach whole length of work plane, but can't surmount rib length time, in order to make coal mining machine roller can cut rib, also need to excavate otch.
Can adopt the feed mode of cutting sth. askew to make coal mining machine roller incision rib; but coal-winning machine need to go and back running in one section of quite long distance of work plane; and to wait for moving conveyor head and support end head bracket again; nonproductive running time of fully-mechanized mining equipment and downtime are increased; cause fully-mechanized mining equipment production efficiency to reduce, coal mining output reduces.
In sum, the otch at fully-mechanized mining working two ends is key factors that guarantee coal-winning machine normal operation, improve fully-mechanized mining equipment productivity ratio.At present, be to adopt hand-holing explosion coal-falling, manually hovel coal excavation otch from one place to another substantially.There is the problems such as operating efficiency is low, consumption of materials is large, potential safety hazard is many, the performance of restriction fully-mechanized mining equipment high-yield and high-efficiency performance.
