The structural representation of a kind of rotary digging driller mast that Fig. 1 provides for the utility model embodiment one; The structural representation of a kind of rotary digging driller mast that Fig. 2 provides for the utility model embodiment two; The structural representation of a kind of rotary digging driller mast that Fig. 3 provides for the utility model embodiment three; The structural representation of a kind of rotary digging driller mast that Fig. 4 provides for the utility model embodiment four.
See Fig. 1, the rotary digging driller mast that the utility model embodiment one provides comprises mast body 10 and is arranged on the guide rail 20 of mast body 10 both sides, particularly, mast body comprises front shroud 11, back shroud 12, left plate 13 and right plate 14, as shown in the figure, front shroud 11, back shroud 12, left plate 13 and right plate 14 are interconnected to form mast cavity, and the front portion in described mast cavity is provided with stiffener 30.Front shroud 11 in this embodiment is one block of smooth steel plate, and stiffener 30 is located between left plate 13 and right plate 14, and parallel with front shroud 11.Also be provided with a gusset 40 between front shroud 11 and stiffener 30, this gusset 40 is preferably vertical with front shroud 11 to be arranged.In addition, as preferably, the position that the front shroud 11 in this embodiment is connected with left plate 13, right plate 14, aligns with the rear wall of guide rail 20.
It should be noted that, although the quantity of gusset 40 shown in figure is one, the quantity of this embodiment to gusset 40 does not limit, can according to practical structures need polylith gusset is set.Between the present embodiment middle guide and mast body, and each side plate of mast body, stiffener, connected mode between gusset are preferably welding.
After above-mentioned connection, the front shroud that the mast of this embodiment adopts in its cavity front portion and stiffener, effectively can strengthen the impact resistance of guide rail and both sides side plate, the stress of two side rails and side plate can be reduced in the course of the work, and the welded seam of energy available protecting guide rail and side plate, prevent weld cracking, thus improve the application life of mast guide rail; The double-decker of front shroud and stiffener composition, in order to connect the guide rail of both sides, two side rails are made to become an entirety, the integral rigidity of lift rail, two side rails keeping parallelisms can be controlled further and be positioned at same plane simultaneously, reducing the wearing and tearing unnecessary between unit head balladeur train and guide rail slid against on guide rail; Compared with existing rotary digging driller mast, the bending resistance of rotary digging driller mast of the present utility model is stronger, and mast integral rigidity also gets a promotion, thus greatly promotes the complete machine stability of rotary drilling rig.
See Fig. 2, it illustrates the structural representation of a kind of rotary digging driller mast that the utility model embodiment two provides.Identical with embodiment one, the mast body 10 of the rotary digging driller mast in this embodiment two comprises front shroud 11, back shroud 12, left plate 13 and right plate 14, and surround mast cavity, mast body 10 both sides arrange guide rail, mast cavity front portion arranges stiffener 30, is provided with gusset 40 between stiffener 30 and front shroud 11.
With above-described embodiment unlike, in this embodiment two, front shroud 11 and two guide rails 20 design for integral type, and namely front shroud 11 and guide rail 20 are that same steel plate bending is shaping, and guide rail 20 and biside plate are being welded.This structure can strengthen the globality of guide rail and mast body further, the integral rigidity of lift rail, improves the corresponding effect in embodiment one further.
See Fig. 3, it illustrates the structural representation of a kind of rotary digging driller mast that the utility model embodiment three provides.The mast body 10 of these rotary drilling rig diseases caused by external factors is slightly different from the structure of guide rail 20 and embodiment one.Front shroud 11 and the back shroud 12 of this embodiment middle mast body 10 are fold-line-shaped, thus form a groove in the front portion of mast body 10, and the stiffener 30 in this embodiment comprises two pieces, be arranged at respectively between front shroud 11 and left plate 13, between front shroud 11 and right plate 14.
The part that stiffener 30 is preferably straight with front shroud 11 is parallel (as shown in the figure, parallel with middle part with front shroud 11 two ends, namely vertical with both sides side plate), stiffener 30 aligns with the rear wall of guide rail 20 substantially with the link position of left plate 13, right plate 14, all identical with embodiment one.
Although this embodiment is not shown, it will be appreciated by those skilled in the art that and can arrange gusset equally in this embodiment, its connected mode can with reference to embodiment one.
The structure of the mast body 10 in this embodiment three itself can promote the rigidity of self, that mast body has stronger impact resistance, and add stiffener 30 on this basis, front shroud 11 and stiffener 30 form the double-decker of " abnormity ", equally can the entirety of lift rail, thus promote its rigidity.Other beneficial effects are also identical with embodiment one, repeat no more.
Further, see Fig. 4, it illustrates the structural representation of a kind of rotary digging driller mast that the utility model embodiment four provides.The mast body 10 of this rotary digging driller mast is identical with the structure in embodiment one with the structure of guide rail 20.With embodiment one structure unlike, the stiffener 20 in this embodiment three has two pieces, and is separately positioned between front shroud 11 and left plate 13, between front shroud 11 and right plate 14, is namely arranged at two angles of mast cavity front portion.
In addition, although this embodiment is not shown, it will be appreciated by those skilled in the art that and can arrange gusset equally in this embodiment, its connected mode can with reference to embodiment one.
This structure design can promote the integral rigidity of mast body equally, effectively strengthens the impact resistance of guide rail and both sides side plate, reaches the beneficial effect similar to embodiment one.
It should be noted that, guide rail in the utility model above-described embodiment is hollow structure, namely left plate and right plate is soldered to by steel plate bending, form the guide rail of hollow, but in other embodiments, in order to strengthen the rigidity of guide rail further, guide rail can also be configured to solid construction, namely adopt solid steel to be soldered to left plate and right plate as guide rail.
Correspondingly, the utility model embodiment also provides a kind of rotary drilling rig, and it is provided with any one rotary digging driller mast in above-described embodiment.Therefore, this rotary drilling rig also has beneficial effect same as the previously described embodiments, repeats no more.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
