Description

[Detailed description of the invention] [Field of industrial application] This invention uses a clamping method using the rail and a roller piece that fits on the rail to attach the concrete cutting machine that moves on the running rail, and when installing This invention relates to a mounting device for adjusting the gap between the two.

[Conventional technology]

Conventional methods for attaching the main body of this type of concrete cutting machine, which is movable on a running rail, to the rail include inserting it from one end of the rail into a slide block at the base of the main body, or configuring the slide block in two. The conventional method was to attach and connect the rail by holding it in from both sides of the rail. However, all of these methods have problems such as requiring time for setup and being laborious and complicated in on-site work.

[Means for solving the problem]

Therefore, this idea has been developed with a simple clamp-type mounting device that allows you to adjust the gap at the same time as assembly by attaching the concrete cutting machine body from above to any position on the running rail with one touch and tightening the gap adjustment knob, allowing you to start work immediately. It is.

To explain the gist, plate-shaped guide rails are installed in the 45° direction on the left and right end edges of the upper surface of the running rail, and the slide block that fits into the running rail of the concrete cutting machine main body is formed with a cross-sectional shape.
A fixed roller piece that fits into the lateral protruding edge of the guide rail was installed near both inner ends of the slide block on the cutter blade side, and was further attached to the outside at the center of the inside of the slide block on the opposite side from the blade. It consists of a movable roller piece similar to the above-mentioned fixed roller piece that can be moved left and right using a gap adjustment knob. A slide block is freely attached from the top of the running rail, and the gap is adjusted by moving the movable roller piece using the gap adjustment knob. ,
This is a clamp type mounting device that holds the guide rail of the traveling rail using three roller pieces.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In a concrete cutting machine main body 20 that is movable on a running rail 10, a plate-shaped cutter is cut in a 45° direction on both left and right end edges of the upper surface of the running rail 10. guide rail 1
1, and a slide block 21 that fits onto the running rail 10 of the concrete cutting machine main body 20.
is formed into a square cross-section, and fixed roller pieces 22 having grooves that fit into the lateral protruding edges 12 of the guide rail 11 are attached near both inner ends of the slide block 21 on the cutter blade 30 side, and further the slide Block 21 cutter blade 30
At the center of the inner side on the opposite side is a movable roller piece 24 having a groove similar to the fixed roller piece 22, which can be moved left and right by a gap adjustment knob 23 mounted on the outside.
It is made by attaching. In addition, in the drawing 2
5 is a feed shaft, and 26 is a feed gear box.

[Effect]

In this device, the gap adjustment knob 23 attached to the slide block 21 of the concrete cutting machine body 20 is rotated all the way to move the movable roller piece 24 outward, and the slide block 21 is placed over any desired point of the running rail 10 to first fit the groove of the fixed roller piece 22 into the guide rail 11 of the running rail 10, and then the gap adjustment knob 23 is turned to fit the groove of the movable roller piece into the guide rail 11 on the opposite side, adjusting the gap adjustment knob 23 so that it can be moved freely. In this way, the concrete cutting machine body 20 can be moved back and forth to perform work.

[Effect of idea]

As explained above, the present invention can be installed almost with one touch by placing the slide block of the concrete cutting machine main body over any part of the traveling rail, fitting the roller piece to the guide rail, and tightening one of the movable roller pieces. This clamp-type mounting device has many advantages, such as being able to adjust the gap and shortening the work setup time, and being easy to operate, simple in structure, and less likely to break down.
