KR20070017225A - The multi angle boring machine attached to a excavator and its excavating method of under the ground - Google Patents

Abstract

The present invention relates to a multi-angle perforator and a method of underground drilling thereof used by attaching to an excavator, which will be described in more detail, without damaging the existing structure of the road and river or the side of the building and the underground structure of the lower and horizontal And it relates to an excavator-attached multi-angle boring machine penetrating obliquely and a drilling method thereof.

Conventionally, in various branch pipe works in which water, sewage pipes, gas pipes, or communication pipes are buried in the ground, the branch pipes to be installed must be buried through the lower ground of the side port, which is a previously installed drainage channel. Excavation work is not necessary due to excessive work time and manpower, and it is not easy to fill up after manual excavation in a large space that is more than necessary when laying branch pipes. There were closures such as road and building damage.

The invention of the invention is to attach a multi-angle perforator instead of a bucket to the bucket connection of the above-mentioned excavator, but the rear end of the multi-angle perforator equipped with a reduction gear and a hydraulic motor and a screw equipped with a diamond tip at the tip, it is driven by hydraulic In this way, the lower part of the structure is drilled vertically, horizontally, and inclined in the ground, which is not only the original function of the excavator, but also drills quickly in various directions without damaging the underground structure, saving work time and manpower, and reducing after work defects. By doing so, there is an effect of improving workability.

The present invention relates to an excavator-attached multi-angle boring machine and its underground drilling method, which will be described in more detail, without damaging the existing structure of the road or river embankment or building side and underground, and the drilling machine and drilling method for penetrating the lower portion thereof It is about.

Conventionally, in the large pipeline construction in which water, sewage pipes, gas pipes, or communication pipes are buried in the ground, a method of horizontally installing large steel pipes passing through the lower part of the structure without cutting existing roads, rivers, or underground structures is used. However, this has the disadvantage of having a large space and strong noise and vibration due to the use of a strong indentation method.In various branch pipe constructions, the branch pipe to be installed is passed through the lower ground of the side opening, which is a drainage channel installed. It is necessary to bury the structure. For this purpose, by crushing the structure or carrying out excavation work by manpower, work time and manpower are excessively consumed, and workability is reduced, and the filling work is easy after manual excavation of a large space more than necessary when laying branch pipe. Because of this, the ground subsidence There were evils such as roads and buildings destroyed.

The present invention has been made to solve the above problems, the present invention is to penetrate the lower portion of the structure without damaging the side of the ground and the existing structure buried in the underground water and sewage pipe or gas pipe or telecommunication pipe It relates to a multi-angle boring machine for embedding a back and a method of drilling the same, which attaches the multi-angle boring machine to the bucket connection part of the excavator, and connects the reducer (6) and the hydraulic motor (7) to the rear of the multi-angle boring body (1). A screw 14 is installed at the tip of the body of the perforator to install the screw 14 at the tip 10 of the diamond tip 11 at the tip, thereby rotating the drive by hydraulic pressure of the excavator to excavate the structure without damaging the underground structure. Perforating the lower part of the structure in the horizontal, vertical and inclined directions depending on the application.

This will be described in detail with reference to the drawings as follows.

As shown in FIG. 1, the structure of the multi-angle perforator body 1 installed at the lower side of the excavator has two pin holes 2a formed at the upper left and right sides of the perforator body 1 so that the bucket connection part and the fastening pin of the upper part ( 2) and a circular hole is formed at the center of the front and rear sides of the body 1 so that a cylindrical rotation shaft 4 is inserted into the body 1 between the front and rear holes. At the outer periphery of the seal 16, the tapered roller bearing 19 and the retaining ring 17 is fastened by a bolt (18) and combined, and then inserted into the front side of the rotary shaft (4) and after the rotary shaft (4) A tapered roller bearing 19 and a coupling 5 are inserted into the side to connect to the reducer 6, and a hexagonal fitting portion 4a is protruded at the center of the tip of the rotary shaft 4, and a key groove is formed at the upper periphery of the rear end thereof. (4b) is formed in concave shape, and through this rotating shaft (4) and the coupling (5) A key groove 6a of the same size is formed in the tip protrusion of the reducer 6 to be fastened, and a key groove 5a of the same size is formed in the inner periphery of the coupling 5, so that the rotary shaft 4 and the reducer ( 6) and the fastening key 8 is inserted into the key grooves 4b and 6a and 5a of the coupling 5 and tightly tightened, and the hydraulic hose 13a and the outflow hose are provided at the rear side of the reducer 6. A hydraulic motor 7 equipped with a 13b is mounted, and a hexagonal fitting portion 4a protrudes out of the tip hole of the body 1 at the tip center of the rotary shaft 4, and the rotary shaft 4 Hexagonal recessed grooves 9a are formed at the rear of the first operating tool 9 to be engaged with the first operating tool, and a hexagonal protrusion 9b is protruded from the front end of the first operating tool 9 and the first operating tool 9 The second work is formed in the outer periphery of the body screw 14 is formed in a spiral shape and the pin 12 is inserted into the protruding portion 9b of the first operating port 9 by inserting and fastening Hexagonal recessed grooves 10a are formed in the rear of the sphere 10, and screws 14 are spirally formed in the outer periphery thereof, and the excavation diamond tip 11 is formed at the center of the distal end of the second operation port 10. ) Is constructed with a mounted structure.
