The utility model take compressed air as the elliptical gear power source of tup, first the utility model utilizes the fragmentation of compressed air-driven tup realization to rock, and suitable granularity can be crushed to, then utilize the air driven rock slag of the band pressure that should discharge and discharge rock hole, namely this take full advantage of the energy and turn avoid water wasting and the contaminated environment that mud in prior art discharges mode, simultaneously, the efficiency of fractured rock can be mated with the efficiency of discharging rock slag again, finally greatly improves drivage efficiency and the economic benefit of rig.
Accompanying drawing illustrates:
Fig. 1 is the structure cross-sectional schematic of an embodiment of the present utility model.
Detailed description of the invention:
Provide concrete embodiment in detail by reference to the accompanying drawings, it should be noted that the description of detailed description of the invention is interpreted as is be convenient to understand the utility model, and should not be considered as being the restriction to claims.
Refer to Fig. 1, specific embodiment of the utility model is as follows: comprise cylinder sleeve 1, cylinder sleeve 1 is cylindrical, form main hammer body part, the front end of cylinder sleeve 1 is connected with the joint 2 of a band air inlet 6, front end is herein the left end of parts in Fig. 1, therefore rear end is the right-hand member of finger, the connection of joint 2 and cylinder sleeve 1 is for being threaded or other anatomical connectivity, key is that the rear end of cylinder sleeve 1 connects a card drill sleeve 3, the tup 4 of a band steam vent 7 is provided with in card drill sleeve 3, tup 4 can in card drill sleeve 3 slide displacement one segment distance, this segment distance essence is the acceleration distance of tup 4 when being subject to impact force, a flap valve is provided with in the air flue of joint 2, the front end of flap valve is against the gas port position of joint 2, the rear end of flap valve is provided with a distribution seat 8, the piston 5 of the slidably displacement of a band centre bore 9 is provided with between distribution seat 8 and tup 4, cavity between piston 5 front end and distribution seat 8 is air chamber 10, when there are gases at high pressure in air chamber 10, driven plunger 5 is moved right, cavity between piston 5 rear end and card drill sleeve 3 is the second air chamber 11, when there are gases at high pressure in the second air chamber 11 by driven plunger 5 to left movement, the front end of tup 4 is provided with a bit shank sleeve 12, the inside wall that cylinder sleeve 1 is positioned at air chamber 10 is provided with a gas-distribution pipe 13.In above-mentioned structure, be formed to the first gas flow channel of the second air chamber 11 through the air inlet of distribution seat 8, gas-distribution pipe 13 to gas-distribution pipe 13 and the gap of cylinder sleeve 1, and the second flow channel of air can be formed through the steam vent of the endoporus of distribution seat 8, piston 5 and tup 4; Described flap valve has a valve seat 14, is provided with a spring 15 in the atrium of the rear end of valve seat 14; Described distribution seat 8 has a through hole, and its front end can be stretched into the atrium of above-mentioned valve seat 14 and adapt with spring 15, and the rear end of distribution seat 8 is the protuberance 16 of a minor diameter.During actual use, the gases at high pressure of extraneous air compressor enter the air flue of joint 2 through the air inlet 6 of joint 2, and promote flap valve and move right, gases at high pressure enter in cylinder sleeve 1, when tup 4 touches rock surface, tup 4 promotes piston 5 and moves to left, inwall due to cylinder sleeve 1 has the cannelure of ventilation, piston 5 side surface is provided with U-type groove and gas-distribution pipe 13 external surface is fluted and pore, move to left in process at piston 5, above-mentioned cannelure, U-type groove, groove and pore (not shown) form aforesaid first gas flow channel, gases at high pressure are inputted the second air chamber 11, at this moment the gases at high pressure in the second air chamber 11 continue to promote piston 5 and move to left, then the centre bore 9 of the rear end of piston 5 departs from the bit shank sleeve 12 on tup 4, at this moment the gases at high pressure in the second air chamber 11 pass through the external surface of centre bore 9 to tup 4 of bit shank sleeve 12 and tup 4, gas declines rapidly and gas-powered tup 4 is discharged with the rock slag of rock surface, while piston 5 continues according to inertia to move to left, the first above-mentioned gas flow channel is closed because piston 5 is positioned at diverse location, moving to left of piston 5 will make the front end of piston 5 contact with distribution seat 8, because distribution seat 8 has a through hole, adapt with spring 15 in the atrium that above-mentioned valve seat 14 can be stretched in its front end, and the rear end of distribution seat 8 is the protuberance 16 of a minor diameter and coordinates with piston 5, now gases at high pressure enter air chamber 10, gas pressure sharply rises and promotes distribution seat 8 and moves to left, when gas continue to enter air chamber 10 pressure is increased again time, drive of high-pressure gas piston 5 moves to right rapidly and hits tup 4, tup 4 is made to move to right fast and impact rock surface, realize the fragmentation to rock.
For realization is to the better crushing efficiency of rock and discharge gases at high pressure, disappointing groove (not shown) is provided with on tup 4 surface, this disappointing groove is straight trough or helicla flute, when above-mentioned tup 4 reaches the very small distance before the limit of impact, the gases at high pressure of air chamber 10 are discharged by the groove that loses heart; If disappointing groove is straight trough, tup 4 is according to inertia straight line shock; If disappointing groove is helicla flute, then tup 4 has a rotary motion while straight line shock, the crushing effect to rock can be improved, change the impact position of tup 4 pairs of rocks simultaneously, the carbide bit 17 that multiple ring-type is arranged particularly is provided with on tup 4 surface, rotation can constantly change the shock point of cutter head 17 pairs of rocks and have a side impacting force to rock, very favourable to the fragmentation of rock.Aforesaid motion iterative cycles carries out, and realizes the bump fragmentation of rock and the Continuous Drive of gases at high pressure and discharges.
In actual use, the impact type quartering hammer that the utility model provides, should be arranged in a large hammer body with multiple boundling and be formed a kind of boundling jump bit, namely the multiple the utility model in boundling jump bit impact rock simultaneously, crushing effect is better, and the diameter of boundling jump bit just can be prepared into larger to hold multiple the utility model, described boundling jump bit is provided with passing away and the gathering-device of the rock slag of drive of high-pressure gas, then can realize better expulsion efficiency.
