Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to FIGS. 1 to 3: combination formula is mount pad for rotary impactor, including base 1 and installation department, the installation department is connected with the base, the installation department is equipped with the mounting hole 5 that runs through installation department length direction to and be located the first connecting hole 2 of mounting hole both sides, installation department and base are vertically passed to first connecting hole, and its central axis is perpendicular with the central axis of mounting hole 5.
In the embodiment, the mounting part is connected with the base 1 in the vertical direction, the first connecting holes 2 are arranged on two sides of the mounting hole 5, the first connecting holes 2 are distributed on two sides of the mounting hole 5 and are oppositely arranged, and each side is provided with three first connecting holes 2, so that the total number of the six connecting holes is six; preferably, the first connection holes 2 are equally spaced on the mounting seat. The depth of the first connection hole 2 is a penetration installation portion so that two installation bases can be connected together by a bolt.
The base 1 is provided with a fixing portion 4 along one side of the extending direction of the mounting hole 5, the fixing portion 4 is arranged on the left side of the base 1 as seen from the direction in fig. 1, the fixing portion 4 is provided with four second connecting holes 3, wherein the size of the two second connecting holes 3 near the middle is smaller than the size of the second connecting holes 3 at the two sides. The size of the two second connecting holes 3 close to the middle is smaller than that of the second connecting holes 3 at the two sides, the two second connecting holes close to the middle are pin holes 31, and the two second connecting holes at the outer sides are threaded holes 32. Through the cooperation of adopting cotter hole and screw hole to use, can be so that the more firm connection impacter of mount pad.
An extension region 6 is disposed at the first connection hole 2 far from the second connection hole 3, the first connection hole 2 far from the second connection hole 3 is the first connection hole 2 farthest from the second connection hole 3, and the extension region 6 is disposed at the first connection hole. And a third connecting hole 7 is arranged on one side of the expansion area 6 far away from the fixed part 4, and the third connecting hole 7 is parallel to the direction of the mounting hole 5, so that the expansion area 6 is communicated with one end of the mounting part far away from the fixed part.
The expansion area is arranged so that when the subsequent mounting seat is mounted on the impactor, a drill bit clamping sleeve is arranged at the joint of the impactor and the drill bit, a spring is arranged on the outer side of the drill bit clamping sleeve, one end of the spring extends into the third connecting hole, an external thread is arranged at the end part of the spring and extends out of the third connecting hole to be located in the expansion area, a nut is screwed into the end part of the spring, and the expansion area is used for expanding the operating space at the position, so that the nut is conveniently screwed in and the spring is fixed.
The base 1 and the mounting part are integrally formed. The cross section of the mounting seat is of a trapezoidal structure, so that after the impacter and the mounting seat are combined, the two mounting seats can be attached tightly, and materials are saved compared with a square mounting seat.
The mounting seat in the embodiment is designed to connect two types of impactors together so as to simultaneously drill holes into the ground. The mounting hole 5 is largest in size and used for placing an impactor in the mounting hole 5, and the mounting hole 5 is connected with an impactor shell through a second connecting hole 3 in the mounting seat through a bolt, so that the mounting hole 5 is tightly connected with the impactor shell; after the installation of the installation base 300 and the impacter is completed, the two installation bases with the impacters are connected together through the first connecting hole 2 through the bolt, and the two impacters are used together. The mounting seat and the impactor adopt a split structure, so that the processing is simple, the impactor can be replaced after the impactor is damaged, the mounting seat can be repeatedly used, and the cost is greatly reduced.
In this embodiment, when in use, the mounting base 300 is used in cooperation with a single-body impactor 11, the mounting base 300 is sleeved on an outer cylinder of the impactor and then is mounted on the bracket 200 through a bolt connection, so as to form the combined rotary impactor 100, and each combined rotary impactor 100 is formed by combining two single-body impactors 11.
In the embodiment, the bracket 200 comprises a guide rod 13 and a connecting part 9, and one end of the connecting part 9, where the flange plates of the two single impactors 11 are located, is fixedly connected to a connecting plate 10 extending out of the left side and the right side of one end of the connecting part 9, which is close to the guide rod 13, through bolts; the two single impactors 11 are symmetrically arranged on two sides of the guide rod 13, and the mounting seat 300 on the outer wall of the outer cylinder of the single impactors 11 is fixedly connected with the guide rod 13 through bolts.
The length of the guide rod 13 is greater than that of the single-body impactor 11, and the guide rod 13 plays a role in guiding when the combined rotary impactor 100 works; before the combined rotary impactor 100 is used, a small hole with a diameter slightly larger than that of the guide rod 13 is drilled in the area to be drilled, the depth of the small hole is the depth of the large hole to be drilled, the guide rod 13 of the combined rotary impactor 100 extends into the small hole, the combined rotary impactor 100 rotates to drill downwards, and the guide rod 13 advances along the small hole to guide the combined rotary impactor 100.
The drilling is carried out in the rotating mode, and the efficiency of large-range drilling is greatly improved. For example, if the diameter of the drill bit 12 of each single-body impactor 11 is 1m and the diameter of the middle guide rod 13 is 1m, the diameter of the combined rotary impactor 100 can be regarded as 3 m; the hole diameter of 1m can be punched in the area to be drilled in advance, and the depth is the depth planned for drilling in advance; the combined rotary impactor 100 is adopted to drill holes, because the combined rotary impactor 100 drills holes downwards through the whole body, the area of single drilling hole is 2.25 pi, but because the hole diameter of 1m is drilled in advance, the area of the single drilling hole of the combined rotary impactor 100 is actually 2 pi by subtracting the area of the single drilling hole which is guided by the guide rod 13 by 2.25 pi; and in the case that the bit 12 of the single-body impactor 11 is 1m, the hole is drilled separately, and the area of each drilling is 0.25 pi. Thus, the combined rotary impactor 100 is far more efficient in drilling a large area than the single body impactor 11 alone.
In this embodiment, one end of the connecting portion 9, which is far away from the guide rod 13, is connected to the drilling machine, a cavity is provided inside the connecting portion 9, a hole is provided in the middle of the connecting portion 10, the cavity inside the connecting portion 9 is connected to the single-body impactor 11 through the connecting portion 10, and high-pressure gas enters the impactor from the drilling machine through the cavity to perform the operation of the impactor.
In the embodiment, the connecting part 9 is far away from one end of the guide rod 13, pulleys 8 are arranged on two sides of the connecting part 9, and the farthest distance between the two pulleys 8 is equal to the farthest distance between the drill bits 12 on the two single impactors 11; the maximum distance is defined herein as: the distance of the two pulleys 8 to one side from each other and the distance of the two drill bits 12 to one side from each other. The pulleys 8 are arranged to further play a guiding role, and the two pulleys 8 can slide on the hole wall of the drilled hole, so that the single-body impactor 11 is prevented from being deviated.
The above technical features can be understood and implemented by those skilled in the art through the text description, and therefore, the accompanying drawings are not needed to be described.
