[Detailed description of the invention]

[00011

[Industrial Field of Application] The present invention relates to a shoe for a ski slope maintenance vehicle. [0002] [Prior Art] Fig. 13 shows a shoe of a conventional ski slope maintenance vehicle.
, 149 To explain with reference to FIG. 15, 1 in FIG.
18 is a wheel that supports the crawler belt 16 in a cyclically movable manner together with the sprocket 17, and 15 is a shoe body attached to the crawler belt 16. [0003] Figure 151 showing details of this shoe 15 Figure 1
In 6, 8 is a bolt, 9 is a washer, and 10 is a holding plate. 11 is a mounting hole provided in the rubber bell 1-1 of the crawler track 16, 12
is a screw hole provided in the shoe body 15, and 14 is a wheel track portion on the side of the rubber belt 1 that contacts the transfer member 18, and the bolt 8 is inserted into the mounting hole 11 of the rubber belt 1 through the washer 9 and the holding plate 10.
The threaded portion of the port 8 is screwed into the screw hole 12 of the shoe body 15, and the shoe body 15 is removably fixed to the rubber belt 1. [0004]

[Problems to be Solved by the Invention] The shoe of the conventional ski slope maintenance vehicle shown in FIGS. . That is. (1) The shape and arrangement of the shoe body 15 cannot be easily changed depending on the ski slope conditions such as snow quality. (2) When the tip of the shoe body 15 becomes worn or damaged, the entire shoe body 15 needs to be replaced. There was a problem. [0005] The present invention has been proposed in view of the above-mentioned problems, and its purpose is to allow easy replacement and to easily change the shape and arrangement of the shoe body. Also, if the tip of the shoe body becomes worn or damaged. The object of the present invention is to provide a shoe for a ski slope maintenance vehicle in which only the shoe body part other than the shoe mounting member can be replaced. [0006]

[Means for Solving the Problems] In order to achieve the above object, the shoe of the ski slope maintenance vehicle of the present invention includes a shoe attachment member fixed along the width direction of the crawler to a rubber belt constituting the crawler, and a shoe attachment member fixed to the rubber belt constituting the crawler along the width direction of the crawler. The shoe body is detachably fixed to the member via a bolt. [0007]

[Operation] The shoe of the ski slope maintenance vehicle of the present invention is constructed as described above, and when replacing the shoe body, the bolts are removed and the shoe body is removed from the shoe mounting member on the track (rubber belt) side. The shoe body is attached to the shoe attachment member, and then a bolt is screwed into a screw hole provided in the shoe body and a screw provided in the shoe attachment member to removably fix the shoe body to the rubber belt via the shoe attachment member. [0008]

[Example] Next, the shoe of the ski slope maintenance vehicle of the present invention is shown in Fig. 1.
To explain with the embodiments shown in FIGS. 7 to 7, FIGS. 1 and 2.
1 is a rubber belt constituting an endless crawler track, 2 is a shoe attachment member, 7 is a fitting groove provided along the width direction of the crawler on the front and rear sides of the shoe attachment member 2, and 5 in Figure 3 is a groove on both sides. Aggressive shoe body with outward curves 9 Figure 4 Passive shoe body with both sides curved inward 7 Figure 3
5a in FIG. 4 are two protrusions having a trapezoidal cross-section that are protruded from the inner surface of the shoe body 5 in a facing state, and each of the protrusions 5a is a fitting portion provided on the front and rear sides of the shoe mounting member 2. The track is fitted into the groove 7 so as to be slidable in the width direction of the track. [0009] Also, in Fig. 17, 8 and 8'' in Figs.
The mounting hole 12 is a screw hole provided in the shoe mounting member 2. The shoe body 5 needs to be replaced in the case of the ninth order. That is. (1) When the ski slope conditions such as season, snow quality, and topography change, or when changing the shoe arrangement 1 width and pitch according to the ski slope conditions 2 For example, from the aggressive type shoe body 5 in Figure 3 to the passive type shoe in Figure 4 Should I replace it with main unit 5? Or vice versa, you need to replace it. (2) Also, if the tip of the shoe body 5 is worn out or deformed, it is necessary to replace it with a new shoe body 5. [00101 When replacing the shoe body 5, remove the bolt 8°, remove the shoe body 5 from the shoe attachment member 2 on the rubber belt 1 side, and then attach the protrusion 5a of another shoe body 5 to the shoe attachment member 2. Fit into the groove 7, then screw the bolt 8 into the screw hole provided in the shoe body 5 and the screw hole provided in the shoe mounting member 2, and then attach the shoe body 5.
is removably fixed to the rubber belt 1 via the shoe attachment member 2. [0011] Next, the shoe of the ski slope maintenance vehicle of the present invention will be explained with reference to other embodiments shown in FIGS. a pair of outwardly curved passive shoe bodies; 6. 8. 8” is Boruto, 7 is Natsu, 9
9 is a washer, 9 is a nut, 10 is a presser plate, 11 is a mounting hole provided in the rubber belt 1, and 12 is a screw hole provided in the shoe mounting member 2. [0012] In the shoes of the ski slope maintenance vehicle shown in FIGS. 8 and 11, when replacing the shoe bodies 5, 5, the nut 9' and the bolt 8' are removed and the shoe bodies 5, 5 are replaced with the shoe mounting member. 2, then remove the shoe body 5 from 7, then apply another shoe body 5, 5 to both front and rear sides of the shoe mounting member 2. 5 and the shoe mounting member 2 are removably fixed with bolts 8' and nuts 9'. [0013] FIGS. 9 and 12 show an aggressive type shoe in which a pair of shoe bodies 5° 5 are curved inward, and the other parts are constructed in the same manner as in FIG. 8. FIG. 10 shows a pair of shoe bodies 5. This is another embodiment in which a spike 13 is interposed between the outer ends of the shoe body 5.5, and this is detachably fixed to the shoe body 5.5 with a bolt 16 and a nut 17, and the other parts are constructed in the same manner as in FIG. has been done. [0014]

[Effects of the Invention] As mentioned above, when replacing the shoe body of the ski slope maintenance vehicle of the present invention, the bolts are removed. Remove the shoe body from the shoe mounting member on the track (rubber belt) side 7 Next, place another shoe body on the shoe mounting member 7 Next, screw the bolt into the screw hole provided in the shoe body and the screw provided in the shoe mounting member. Since the shoe body is removably fixed to the rubber belt via the shoe attachment member, it is only necessary to attach the shoe body to the shoe attachment member, compared to the conventional shoe body that is attached directly to the abdominal band (rubber belt). , easy to replace, and the shape and arrangement of the shoe body can be easily changed. [0015] Furthermore, when the tip of the shoe body is worn or damaged, only the shoe body portion other than the shoe mounting member needs to be replaced.
