The spiral drill rod can carry out rapid downhole unscrewing, so as to increase construction speed and ensure construction safety.
Description
Technical field
The utility model relates to auger stem, the auger stem of more specifically saying so and using under coal mine.
Background technology
In the coal mine down-hole drilling work progress, auger stem obtains using quite widely with its good deslagging effect.
In the prior art, because the restriction of equipment and instrument, boring is more shallow in addition, all uses dental forceps basically for the unloading of drilling rod.Less when drill pipe diameter, when rig power is little, use dental forceps unloading drilling tool, though efficient is lower, safety relatively also generally.
In recent years,, require that gas control aspect safety factor increases, speeds up, efficient improves along with the development of coal mining enterprise, and the more and more difficult requirement of satisfying gas control of original minor diameter shallow bore hole.Therefore, the construction of major diameter, long drilled holes is arisen at the historic moment, and high-power rig that is complementary with it and major diameter drilling rod are widely used thereupon.In the process of using high-power rig, major diameter drilling rod construction long drilled holes, not only efficient is low but also be absolutely unsafe to use traditional dental forceps unloading drilling rod, use dental forceps unloading drilling rod at present, dismantling a drilling rod in 5~6 minutes is normal thing, particularly when drilling rod very tight and when using sledgehammer to pound button, not only speed is slow but also can destroy the drilling rod screw thread, thereby influences its application life, sometimes even twist into two parts dental forceps, this strengthens working strength of workers and may workman's health be damaged.
The at present conventional drilling rod that uses, all cross sections of front end of its core pipe and kelly are circular entirely, therefore can only use phase class instrument such as dental forceps to carry out the clamping unloading, this mode has greatly limited the raising of operating efficiency.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of auger stem of unloading fast is provided, to alleviate working strength of workers, prolong the application life of drilling rod, improve speed of application, guaranteeing working security.
The utility model technical solution problem adopts following technical scheme:
The quick unloading auger stem of the utility model is to be driving mechanism with the drill power head;
Design feature of the present utility model is that the bar front end at kelly is provided with the one-level box; Unloading bars at different levels that join successively with kelly and the backstay that is positioned at unloading bar front end, all be pin threads at different levels to be set at body of rod tail end, at lever front end boxes at different levels are set, and dock mutually with pin thread and the box on the adjacent one-level body of rod towards boring one side; Between driving lever and unloading bar reducer union is set, reducer union is equipped with the big square hole of one end and the bar front end square shaft of driving lever, and reducer union is equipped with the small square hole of its other end and the bar tail end square shaft of unloading bar; At backstay position place, locator is set, locator is to be equipped with the location square shaft of backstay rear setting with wherein location square hole, is used for the clamping backstay and locatees circumferentially obtaining.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model utilizes reducer union to connect driving lever and unloading bar, utilizes the counter-rotating of drill power head can turn on the drilling rod screw thread fast.
2, the utility model is arranged on the bar front end with box on the bodies of rod at different levels, because the pin thread carcass is thicker, processes square shaft thereon and does not reduce its working strength.
3, the utility model adopts square hole and the square shaft positioning form that matches for backstay, and is simple in structure and be convenient to operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model locator structure schematic diagram.
Number in the figure: 1 drill power head, 2 kellies, 21 one-level boxes, 22 front end square shafts, 3 unloading bars, 31 tail end square shafts, 4 backstays, 41 location square shafts, 5 reducer unions, 51 big square holes, 52 small square holes, 6 locators, 61 active plugboards, 62 location square holes, 63 gathering sills.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, present embodiment is to be driving mechanism with drill power head 1, at the bar front end of kelly 2 one-level box 21 is set; Unloading bars 3 at different levels that join successively with kelly 2 and the backstay 4 that is positioned at unloading bar 3 front ends all are at the body of rod tail end pin threads at different levels to be set, at lever front end boxes at different levels are set, and dock mutually with pin thread and the box on the adjacent one-level body of rod towards boring one side;
In concrete the enforcement, between driving lever 2 and unloading bar 3, reducer union 5 is set, reducer union 5 is equipped with the big square hole 51 of one end and the bar front end square shaft 22 of driving lever 2, and reducer union 5 is equipped with the small square hole 52 of its other end and the bar tail end square shaft 31 of unloading bar 3; At place, backstay 4 positions, locator 6 is set, locator 6 is used for clamping backstay 4, makes backstay 4 circumferentially obtain the location.
Shown in Figure 2, the structure setting of locator 6 comprises that sky is enclosed within the fixed support of drilling rod periphery, one active plugboard 61 is set in the fixed support, it is back and forth movable that active plugboard 61 is done by the gathering sill on the fixed support 63, active plugboard 61 is provided with location square hole 62, this location square hole 62 is an opening at a side, by move left and right active plugboard 61 the location square shaft 41 of location square hole 62 and backstay 4 rear settings on it is equipped with, and makes backstay 4 circumferentially obtain the location.
The unloading operating process is carried out as follows fast:
1, the front end one-level box 21 of kelly 2 directly is connected with the tail end pin thread of unloading bar 3, pulls out the unloading bar outside the hole.
2, when the square shaft of backstay 4 is pulled to locator 6 positions, operation locator 6 makes its location square hole 62 match with location square shaft 41 on the backstay 4, and backstay 4 is positioned, and keeps backstay 4 not turn.
3, rightabout rotates drill power head 1, and being connected between the one-level box 21 of turning on kelly 2 and the tail end pin thread of unloading bar 3 withdrawed from kelly 2 from a segment distance backward.
4, with reducer union 5 covering devices on the afterbody square axis of unloading bar 3, the kelly 2 that moves forward then, and the bar front end square shaft 22 of kelly 2 is connected with reducer union 5.
5, the backward rotation kelly 2, remove the screwed connection between unloading bar 3 and the backstay 4.
6, kelly 2 continues the slow astern segment distance, moves reducer union 5 and unloading bar 3 in succession.
7, advance kelly 2 and it is connected with the tail end pin thread of backstay 4 withdraws from the location of 61 pairs of backstays 4 of active plugboard in the locator 6, allows backstay 4 no longer be held, and backstay 4 promptly can rotate.
8, at this moment, backstay 4 promptly becomes the state of unloading bar 3, repeats above course of action and gets final product.
