Detailed Description
The present invention will be described in further detail with reference to embodiments shown in the drawings.
With reference to figures 1-3 of the drawings,
the complex soil-rock mixture drilling anchor cable combined pore-forming device comprises a drilling machine and a drill bit assembled on the drilling machine, wherein the drill bit comprises an eccentric down-the-hole hammer 1 matched with the drilling machine, a twist drill 2 matched with the eccentric down-the-hole hammer 1 in diameter and used for cleaning a drill hole, and a full-length casing protective wall 3 matched with the eccentric down-the-hole hammer 1 in size; the eccentric down-the-hole hammer 1 is installed on a drilling machine, a convex ring 4 is arranged at one end, opposite to the ground, of a full-length casing protective wall 3, the outer ring wall of the convex ring 4 is fixedly connected with the inner wall of the full-length casing protective wall 3, the eccentric down-the-hole hammer 1 is matched with the side face of the convex ring 4, and when the eccentric down-the-hole hammer 1 is located in the full-length casing protective wall 3 and attached to the side face of the convex ring 4, the eccentric down-the-hole hammer 1 knocks the convex ring 4.
The efficiency of drilling by using the eccentric down-the-hole hammer 1 is high, and the equipment is simple. The combination of the twist drill 2 can clean the gravel soil in the drilled hole of the eccentric down-the-hole hammer 1 after drilling, so that the drilling hole is prevented from being blocked. Eccentric down-the-hole hammer 1 cooperates full length sleeve pipe dado 3, in knocking into the drilling with this full length sleeve pipe dado 3 through the mode of hammering, can let sending into of full length sleeve pipe dado 3 more convenient, utilize the inside bulge loop 4 of full length sleeve pipe dado 3, can let eccentric down-the-hole hammer 1 have good striking position, and this bulge loop 4 is the one end of design in full length sleeve pipe dado 3 relative ground, the position that can the application of force is close to the tip on full length sleeve pipe dado 3 relative ground as far as, let send into the effect more stable. In this embodiment, the eccentric down-the-hole hammer 1 projects into the full-length casing retaining wall 3 and abuts against the side of the collar 4, and the full-length casing retaining wall 3 can be inserted into the borehole by hammering of the eccentric down-the-hole hammer 1. After the full-length casing retaining wall 3 is assembled, the influence of collapse and underground water on the anchor cable process can be effectively solved. And in eccentric down-the-hole hammer 1 in the hammering in-process, as shown in fig. 3, can rotate and exert force to bulge loop 4 simultaneously, can appear eccentric down-the-hole hammer 1 in this in-process and strike bulge loop 4's each position in proper order and even, and be not even strike whole bulge loop 4, strike along bulge loop 4 and eccentric down-the-hole hammer 1 complex point at that time, concentrate the dynamics of assaulting on the complex point, can let bulge loop 4's each position put in order in hand, can let the impact even and concentrate.
In order to simplify the equipment, the twist drill 2 is a screw mechanism coaxially arranged on the side wall of the eccentric down-the-hole hammer 1.
The twist drill 2 and the eccentric down-the-hole hammer 1 are directly integrated, the rotation of the eccentric down-the-hole hammer 1 during drilling is utilized to directly drive the screw mechanism, drilling and cleaning can be carried out synchronously, and efficiency is improved.
In addition, a buffer layer 5 is arranged between the convex ring 4 and the eccentric down-the-hole hammer 1. The buffer layer 5 is attached to the surface of the convex ring 4 on the side opposite to the eccentric down-the-hole hammer 1. The buffer layer 5 is made of rubber.
Because the hammering frequency of the eccentric down-the-hole hammer 1 is high and the impact force is large, in order to ensure that the convex ring 4 cannot be accidental under the hammering action, the impact force is properly dispersed and absorbed by the aid of the buffer layer 5, and the impact can be kept concentrated and uniform. The rubber material has strong absorption capacity, and can be configured into different shapes, hardness and the like according to requirements.
More specifically, the buffer layer 5 includes a first layer 51, a second layer 52, and a thrust bearing 53 disposed between the first layer 51 and the second layer 52; the first layer 51 and the second layer 52 are oriented with respect to the torus 4 and the eccentric down-the-hole hammer 1, respectively; the thrust bearing 53 is arranged coaxially with the collar 4 and has a size not larger than that of the collar 4.
The first layer 51 and the second layer 52 are provided mainly to enable relative rotation, and this problem can be alleviated because the eccentric down-the-hole hammer 1 is operated while rotating, and relative friction is likely to occur between the eccentric down-the-hole hammer 1 and the cushion layer 5, and the cushion layer 5 is likely to be torn during rotation of the eccentric down-the-hole hammer 1, and the first layer 51 and the second layer 52 are allowed to rotate relative to each other. The rotational structure employs a thrust bearing 53 that can receive axial forces and is subject to high compressive forces. Because the thrust bearing 53 and the convex ring 4 are coaxial, and the size of the thrust bearing 53 is not larger than that of the convex ring 4, when the second layer 52 is impacted by the eccentric down-the-hole hammer 1, the impact is firstly buffered by the second layer 52 and then acts on the thrust bearing 53, and because of the existence of the first layer 51, the thrust bearing 53 can generate a certain inclination, the impact is transmitted by virtue of the inclination, a part of the impact can be evenly split after the impact is absorbed, the impact is a part with a small area instead of a point, the impact can be kept relatively concentrated, and the installation efficiency of the full-length casing protective wall 3 is accelerated.
In fact, the maximum outer diameter of the path formed by the rotation of the eccentric down-the-hole hammer 1 lies within the collar 4. The eccentric down-the-hole hammer 1 of this design has a range of options for the size. Also within this range, the eccentric down-the-hole hammer 1 and the full-length casing retaining wall 3 are best fitted, and no mutual collision occurs.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
