First, Figure 3 shows the installation state of the present invention, as can be seen through the same figure, the truck 10 of the present invention is the longitudinal direction in the frame 20 and the frame 20 constituting the outside of the main body 20 , The slide plate 30 is mounted to be reciprocated in a direction parallel to the experimental channel 90.

A caster 11 and a vise 12 are installed below the frame 20 to be coupled to the rail 91 at the top of the experimental channel 90, and the caster 11 tracks the rail 91 as shown in FIG. 4. As the trolley 10 moves as the road moves and the vise 12 presses the rail 91, the trolley 10 is fixed to the test channel 90.

In addition, a number of fastening holes 39 are formed in the plate 30 to mount various measuring devices required for repair experiments, and the plate 30 as shown in order to secure the geometric rigidity of the plate plate 30. A plurality of ribs 38 may be formed therein.

5 and 6, the longitudinal axis 25 of which the spiral is formed on the outer circumferential surface of the rectangular frame 20 and the worm wheel 24 is coupled to the center thereof is the longitudinal direction of the frame 20, that is, the experimental channel ( It is installed in parallel with the 90, wherein both ends of the longitudinal axis 25 is coupled to the front end and the rear end of the frame 20 so as to be freely rotatable.

In addition, a horizontal axis 22 having a worm 23 formed on an outer circumferential surface of the center portion is installed across the frame 20, that is, at a right angle to the test channel 90, and both ends of the horizontal axis 22 are respectively frame 20. It is coupled so as to be freely rotatable at both side ends, wherein the worm 23 of the horizontal axis 22 and the worm wheel 24 of the longitudinal axis 25 are installed to engage with each other so that the longitudinal axis 25 is rotated as the horizontal axis 22 rotates. Will rotate.

On the other hand, as shown, one end of the horizontal axis 22 is exposed to the outside of the frame 20 and the handle 26 is coupled can be configured to allow the user to manually operate the handle 26, if necessary, the horizontal axis 22 It is also possible to operate by connecting a motor or the like, but such a driving method is a matter that can be carried out by those of ordinary skill in the art that the present invention belongs to the specific limitations of the claims.

The upper part of the frame 20 is mounted with a slide plate 30 is provided with a plurality of rollers 31 on both sides, the running groove 21 parallel to the experimental channel 90 on both side ends of the frame 20 is provided. Each of them is formed, and the rollers 31 of the slide plate 30 are coupled to these driving grooves 21 to prevent the rollers 31 from being separated and to allow accurate driving.

In addition, as shown in Figure 5, by installing the restraining plate 27 in the driving groove 21 and the roller 31, it is possible to enable a more stable running of the roller (31).

As described above, the roller 30 has a plurality of rollers 31 installed on both sides thereof along the driving groove 21 of the frame 20, so that the longitudinal direction of the bogie 10, that is, the direction parallel to the test channel 90 is provided.
