The invention provides a foldable feeding device for a mine tunnel hydraulic drilling rig. The foldable feeding device comprises a base, and a front-end feeding platform, a middle feeding platform anda rear-end feeding platform which can be spliced together are sequentially arranged on the upper part of the base from front to rear; one ends of a pair of first horizontal telescopic rods are fixedly mounted at the front ends of the two sides of the middle feeding platform correspondingly, first motors are arranged at the other ends of the pair of first horizontal telescopic rods correspondingly, and the first motors drive the front-end feeding platform to rotate to be folded; and one ends of a pair of second horizontal telescopic rods are fixedly mounted at the rear ends of the two sides ofthe middle feeding platform correspondingly, second motors are arranged at the other ends of the pair of second horizontal telescopic rods correspondingly, and the second motors drive the rear-end feeding platform to rotate to be folded. According to the foldable feeding device, when the drilling rig works in a tunnel, a worker does not need to mount a section of drilling rod each time and can mount multiple sections of drilling rods at a time, a water supplying device does not need to be demounted and mounted repeatedly, and the motion journey of a rotating device is increased.
Description
technical field [0001] The invention belongs to the field of drilling rigs, and relates to an accessory device for underground coal mine construction, in particular to a foldable feeding device for a mining tunnel hydraulic drilling rig. Background technique [0002] The main disasters in my country's coal mines include gas, roof, rock burst, fire, water damage, dust damage, heat damage, etc. In recent years, most coal mine accidents in my country are caused by gas explosions, and the gas content in my country's coal mines is relatively high. Drain the borehole, and then drain the gas in the coal seam to reduce the gas content in the coal seam. [0003] Tunnel drilling rig is not only a kind of tunneling equipment but also a kind of exploration equipment. It is widely used in coal mines and oil fields. It is mainly used for gas drainage drilling inside mines, water and coal exploration drilling at various angles, and dust-proof water injection. and drilling for other purpos...
