Abstract
The utility model discloses a rapid pitching mechanism for a sliding frame and a drill boom of a down-the-hole drill. The rapid pitching mechanism comprises a machine base arranged on a machine frame, the drill boom, an upper oil cylinder and a lower oil cylinder, wherein the drill boom, the upper oil cylinder and the lower oil cylinder are respectively hinged to the machine base. The far end of the drill boom and the far end of the upper oil cylinder are respectively hinged to the sliding frame. The far end of the lower oil cylinder is hinged to the upper middle portion of the drill boom. Compared with a traditional layout, the number of supporting points between the sliding frame and the machine base is increased, so that the rigidity of supporting of the sliding frame is increased, the stability of the sliding frame during drilling and pitching is improved, and the rapid pitching mechanism has the obvious effect on a large-scale drill and a drill with a super-long sliding frame. Due to the adoption of reverse linkage of the two oil cylinders, when the upper oil cylinder stretches, the lower oil cylinder retracts, and the sliding frame is erected; when the upper oil cylinder retracts, the lower oil cylinder stretches, and the sliding frame is placed horizontally, so that the pitching speed of the sliding frame is improved through the linkage of the two oil cylinders.
Description
Technical field
The utility model relates to the rapid pitch mechanism of a kind of down-the-hole drill machine sliding frame and drill boom.
Background technology
The down-the-hole drill of extensive use at present, its balladeur train pitching and drill boom pitching are to establish one's own system, respectively action.Balladeur train pitching oil cylinder is to take drill boom as fulcrum, rotates the structure that realizes balladeur train pitching by transverse axis.Between balladeur train and drill boom, mainly with horizontal semiaxis, support, balladeur train center of gravity is not in supporting plane.In addition drill boom pitching is by being positioned at the flexible realization of the oil cylinder of drill boom below, not linking with the pitching of balladeur train.Such balladeur train and the structural configuration of drill boom remove operational motion complexity, balladeur train elevating movement speed slowly outside, for large type drill with need the rig of the longer balladeur train of configuration also all obviously to have balladeur train boring and the poor problem of pitching action stability.For the poor problem of release stability, often need thick drill boom and oil cylinder are set, increased cost and rig weight.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good stability, efficiency is high and the mechanism of the simple down-the-hole drill machine sliding frame of overall structure and drill boom rapid pitch.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of down-the-hole drill machine sliding frame and drill boom rapid pitch mechanism, and its key is: it comprises the support that is arranged in frame and drill boom, upper oil cylinder, the next oil cylinder hinged with support respectively;
The far-end of described drill boom and upper oil cylinder is hinged with balladeur train respectively; The far-end of described the next oil cylinder and the middle and upper part of drill boom are hinged.
Described upper oil cylinder and the next oil cylinder are all positioned at the top of drill boom.
Described balladeur train comprises sliding rack body and compensation arrangement thereof.
The beneficial effect that adopts technique scheme to produce is: 1) this structure has increased the strong point between balladeur train and support compared with conventional in layout, the rigidity of carriage supports is increased, stability while having improved balladeur train boring and pitching, this rig effect for large type drill and overlength balladeur train is fairly obvious.
2) the utility model adopts two oil cylinders oppositely to link, and when upper oil cylinder stretches out, the next oil cylinder shrinks, and balladeur train is erected; When upper oil cylinder shrinks, the next oil cylinder stretches out, and balladeur train is set level, and two oil cylinder interlocks have improved the luffing speed of balladeur train.
3) when structure of the present utility model has caused balladeur train to erect, center of gravity is significantly moved (comparison diagram 1 and Fig. 2) afterwards, and balladeur train center of gravity and rig center of gravity are significantly approached, and while having increased boring, the stability of rig, is conducive to improve drilling efficiency.
Accompanying drawing explanation
Schematic diagram when Fig. 1 erects for this practical balladeur train;
Schematic diagram when Fig. 2 sets level for this practical balladeur train.
In the accompanying drawings: 1, balladeur train, 2, drill boom, 3, upper oil cylinder, 4, the next oil cylinder, 5, support.
The specific embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model comprises the support 5 that is arranged in frame and drill boom 2, upper oil cylinder 3, the next oil cylinder 4 hinged with support 5 respectively; The far-end of described drill boom 2 and upper oil cylinder 3 (being the other end) is hinged with balladeur train 1 respectively; The middle and upper part of the far-end of described the next oil cylinder 4 and drill boom 2 is hinged.During this is novel, by support 5, drill boom 2 and the next oil cylinder 4, form three-legged structure, play main support balladeur train 1.By three-legged structure and support 5, upper oil cylinder 3, balladeur train 1, form four-bar linkage structure, play supplemental support balladeur train 1.By stretching of two oil cylinders, change the shape of trigonometric sum four bar structures, reach the object of balladeur train 1 pitching.Two oil cylinders are carried out interlock, and when upper oil cylinder 3 stretches out, the next oil cylinder 4 shrinks, and balladeur train 1 erects (see figure 1); When upper oil cylinder 3 shrinks, the next oil cylinder 4 stretches out, and balladeur train 1 is set level (see figure 2).Described balladeur train 1 comprises sliding rack body and compensation arrangement thereof, the same with traditional sliding framework structure herein.
As shown in accompanying drawing 1,2, the support being arranged in frame has three hinged seats, hinged with the rodless cavity end of drill boom 2 lower ends, upper oil cylinder 3 and the next oil cylinder 4 respectively from bottom to top; The hinged seat of the rod chamber end of the next oil cylinder 4 and drill boom 2 middle and upper parts is hinged; The front end of drill boom 2 upper ends and balladeur train compensation arrangement is hinged; The rodless cavity end of upper oil cylinder and the rear end of balladeur train compensation arrangement are hinged.
This layout has formed the triangle that support, drill boom and the next oil cylinder form.Because the distance of drill boom on support and the next oil cylinder hinged seat can be larger than the distance of conventional in layout, thereby increased leg-of-mutton stability.Meanwhile, this triangle and support, balladeur train compensation arrangement and upper oil cylinder have formed again four-bar linkage structure, make by a traditional support, to have become two supports between balladeur train and support, the rigidity while greatly having increased balladeur train boring and pitching.This structure has increased the stability of balladeur train compared with conventional in layout, improved the luffing speed of balladeur train, and while having increased boring, the stability of rig, can improve drilling efficiency.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can be in the situation that do not depart from this novel spirit or scope, in other embodiments realization.Therefore, basis is novel will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
