Abstract
The utility model discloses a large diameter drill hammer for a filling pile drilling machine. The large diameter drill hammer for the filling pile drilling machine comprises a common drill hammer 1, wherein the existing diameter of the common drill hammer 1 is 2.8m, the common drill hammer is provided with a group of blade fans 2, vertical extended iron castings 3 are arranged on the end portions of the blade fans, and transverse iron castings 4 are arranged on the bottom portions of the vertical extended iron castings. The large diameter drill hammer for the filling pile drilling machine enlarges diameter of the common drill hammer through a mode that the vertical extended iron castings are welded on the end portions of every blade fans of the common drill hammer with the 2.8m diameter, thereby meeting the drilling requirement of large diameter filling piles in constructional engineering. The large diameter drill hammer for the filling pile drilling machine increases strength by welding the transverse iron castings on the bottom portions of the vertical extended iron castings simultaneously. All welded joints are welded by adopting grooves, and are welded by 506 cast iron welding wires, thereby meeting strength requirements. The large diameter drill hammer for the filling pile drilling machine is simple in structure and convenient to improve, and can meet drilling requirements of the large diameter filling piles in the constructional engineering.
Description
Technical field
the utility model relates to a kind of pile drill and bores hammer by major diameter, and the major diameter belonged in construction work is bored (punching) hole pouring pile rig drilling tool technical field used.
Background technology
along with requirement major diameter in construction work of highrise building is bored in (punching) hole pouring pile work progress, excessive because of hole stake diameter, common brill hammer diameter is 2.8m, can't meet the construction demand.
Summary of the invention
the purpose of this utility model is, provides major diameter for a kind of pile drill to bore hammer, and the common brill hammer that to solve existing diameter be 2.8m of take can't meet the problem of construction demand.
the technical solution of the utility model:
a kind of pile drill bores hammer by major diameter, comprises the common brill hammer that existing existing diameter is 2.8m, and common brill hammer is provided with one group of leaf fan; Leaf fan end is provided with vertical lengthening ironcasting, and the bottom that vertically lengthens ironcasting is provided with horizontal ironcasting.
aforementioned major diameter is bored in hammer, and described vertical lengthening ironcasting comprises two thick 100mm, wide 320mm, the triangle ironcasting of high 500mm, the both sides welding of triangle ironcasting and leaf fan end.
aforementioned major diameter is bored in hammer, and described horizontal ironcasting is a thick 100mm, wide 100mm, the rectangle ironcasting of long 700mm, the bottom welding of rectangle ironcasting and two blocks of triangle ironcastings.
aforementioned major diameter is bored in hammer, and the commissure of described triangle ironcasting and the end welding of leaf fan is provided with weld groove, and weld groove welds through 506 electrode for cast irons.
aforementioned major diameter is bored in hammer, and the commissure of described rectangle ironcasting and the welding of triangle ironcasting is provided with weld groove, and weld groove welds through 506 electrode for cast irons.
compared with prior art, the enlarged diameter that the vertical mode that lengthens ironcasting of each leaf fan end welding that the utility model is hammered into shape by the common brill that is 2.8m at existing diameter is hammered common brill into shape, to meet the boring requirement of large-section in-situ concrete pile in construction work.Bore the intensity of hammer with increase at each vertical horizontal ironcasting of bottom welding that lengthens ironcasting simultaneously.All commissures adopt groove welding, with 506 electrode for cast irons, are welded, to meet the requirement of strength of boring hammer.The utility model is simple in structure, and transformation is convenient, can meet the boring requirement of large-section in-situ concrete pile in construction work.
The accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
the common brill hammer of being labeled as in accompanying drawing: 1-, 2-leaf fan, 3-vertically lengthens ironcasting, the horizontal ironcasting of 4-.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of pile drill bores hammer by major diameter, as shown in Figure 1, comprises the common brill hammer 1 that existing existing diameter is 2.8m, and common brill hammer is provided with one group of leaf fan 2; Leaf fan end is provided with vertical lengthening ironcasting 3, and the bottom that vertically lengthens ironcasting is provided with horizontal ironcasting 4.Described vertical lengthening ironcasting comprises two thick 100mm, wide 320mm, the triangle ironcasting of high 500mm, the both sides welding of triangle ironcasting and leaf fan end.Described horizontal ironcasting is a thick 100mm, wide 100mm, the rectangle ironcasting of long 700mm, the bottom welding of rectangle ironcasting and two blocks of triangle ironcastings.The commissure of described triangle ironcasting and the end welding of leaf fan is provided with weld groove, and weld groove welds through 506 electrode for cast irons.The commissure of described rectangle ironcasting and the welding of triangle ironcasting is provided with weld groove, and weld groove welds through 506 electrode for cast irons.
Embodiment
this example is the improvement of carrying out on the basis of existing common brill hammer, and specific practice is: the common brill hammer 1 that to look for a diameter of having scrapped be 2.8m is complete just can using as long as bore the leaf fan 2 of hammer 1.End face and the both sides of leaf fan are polished, then as shown in Figure 1, in the welding of the both sides of leaf fan, weld respectively a vertical ironcasting 3 that lengthens, vertically lengthening ironcasting is thick 100mm, wide 320mm, the triangle ironcasting of high 500mm; And then, at vertical horizontal ironcasting 4 of bottom welding that lengthens ironcasting, laterally ironcasting is a thick 100mm, wide 100mm, the rectangle ironcasting of long 700mm.Welding, the upper plane of the rectangle ironcasting other end and leaf fan bottom welding align with the outside of triangle ironcasting on the upper plane of rectangle ironcasting one end.During welding, make a call to 45 degree grooves in commissure, then use 506 electrode for cast iron built-up welding, scolder should exceed weld seam 5mm left and right, should be without bubble and impurity, to guarantee weldquality in weld seam.Through improved brill hammer, the vertical lengthening ironcasting 3 of fanning 2 ends by being welded on leaf will bore the hammer radius and lengthen about 300mm, can get out the priming concrete pile hole that diameter equals 3.4 meters, common brill hammer drill (punching) diameter that to have solved with diameter be 2.8m surpasses brill (punching) demand of 2.8 meters priming concrete pile holes.
the old brill hammer that the transformation of this example not only can make to scrap is reused, and has well solved the common brill hammer that existing diameter is 2.8m and can't bore the problem of (punching) diameter over 2.8 meters priming concrete pile holes.
