Description

[Detailed description of the invention] (Field of industrial application) This invention is a new type of new transportation system that aims for smooth running by sliding the guide rails attached to the guide rail support walls on both sides of the track and the guide wheels of the bogie. A dedicated horizontal type that efficiently and sequentially drills three bolt holes in one place of a large number of anchor bolts into the guide rail supports in one operation to attach the left and right guide rails on which the guide wheels attached to the left and right sides of the type vehicle bogie slide. It concerns concrete drilling machines.

(Prior Art) Conventionally, there was no drilling machine for drilling horizontal holes, so a normal vertical type was installed horizontally to perform the drilling. However, in the horizontal direction, the thrust is insufficient compared to the vertical direction, so it is necessary to apply additional thrust with a jack, etc. Also, when drilling a large number of holes, it is necessary to drill them in several steps, which reduces efficiency. There was a problem with the decline.

(Problem that the invention aims to solve) This invention uses several drilling drills in parallel to drill several bolt holes for guide rail mounting anchor bolts on the guide rail support wall provided on both sides of the track. It is constructed horizontally so that it can slide freely on the bed body, and is supported by a screw-type jack attached to the end beam of the body on the opposite side of the drill group, so that several bolt holes can be precisely pitched into the support wall at once. To provide a dedicated vehicle guide rail mounting anchor bolt hole drilling machine for efficiently carrying out the drilling work by sequentially moving the supporting legs of the bed body using casters at the lower end.

(Means for solving the problem) In order to achieve the above purpose, first, a bed body is provided, and casters are attached to the lower end of the bed body at appropriate locations on the front, rear, left and right sides, and screw type jacks are installed on the rear end beam of the bed body. In addition, near the center of the bed body, there is a slide block equipped with a drill motor start switch on the top, and a drilling handle is attached to this.Furthermore, a frame-shaped slider is installed on the bed body, and a slide block is installed at the bottom of the rear end of the slide block. A rack is fixed to the side and meshes with the pinion of the above-mentioned drilling handle shaft so that it can slide back and forth on the bed body.The front end of the slide is supported by a roller running on the bed body, and a rack is attached to the top of the front end of the slider. A plurality of drilling drills are mounted in parallel and connected to a drive motor via a transmission groove, and this is connected to the drill motor start switch on the slide block by wiring.

(Function) In the drilling machine of the present invention configured as described above, the bed body is placed on the roadbed in a direction approximately perpendicular to the track, and the height of the four support legs is adjusted by turning the level handle at the top. . In this case, in the direct course, the bed body is installed horizontally, but in the curved course, the bed body has a cant (slope) on the outside of the curved part, just like a normal track. The height of the front and rear support legs must be adjusted according to the set dimensions, and the height of the front and rear support legs must be adjusted according to the set dimensions. When drilling into the inner wall, on the other hand, set the drill side low. Since the guide rail support walls on the left and right sides of the track base are made of concrete, a diamond bit drill was used, and multiple drills were applied to the designated drilling locations, and the screw-type jacks on the rear end beam were installed in the opposite direction from the drilling side. Support it between the guide rail and the support wall on the side, apply pressure with the screw, turn on the drill motor start switch on the top of the slide block to operate the drill, and gradually turn the drilling handle to send the slider to perform drilling. During drilling, water is supplied to the tip of the drill from a separately provided water tank.

When one drilling operation is completed, the machine body can be moved to the next drilling location, and the machine can be repositioned as described above and the drilling operations can be continued efficiently in sequence.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. A bed body 1 is provided, and casters 3 are attached to the lower end of the bed body 1 at appropriate positions on the front, rear, left, and right sides, and a level handle 4 is attached to the upper end with screws. The bed body 1 is equipped with support legs 2 whose height can be adjusted freely, a screw type jack 5 is installed on the rear end beam of the bed body 1, and a drill motor start switch 6 is installed in the upper part near the center of the bed body 1. A slide block 7 is constructed, a drilling handle 8 is attached thereto, and a frame-shaped slider 1 is attached.
0 is provided horizontally on the bed body 1, and a rack 9 is fixed to the lower rear end of the rack 9, which meshes with the pinion 11 of the 8 axes of the drilling handle to be able to slide back and forth on the bed body 1. The front end is supported by a roller 12 running on the bed main body 1, and three drilling drills 13 are connected to the drive motor 1 in parallel at the top of the front end of the slider 10 via a transmission side 14.
This is connected to the drill motor start switch 6 on the slide block 7 and wired thereto. In the drawings, 16 is a water supply device, and 17 is a water supply hose.

(Effects of the invention) In this way, the drilling machine of the invention can drill the three anchor bolt mounting holes of the guide rail mounting holder into the guide rail support walls provided on both sides of the track at accurate pitches in one operation. This is a dedicated drilling machine that has extremely high efficiency and is easy to install and adjust, making it possible to continue drilling work by moving it one by one.
