(Rail unit)
First, an outline of the structure of the rail unit 2 used in the present invention will be described with reference to FIG. FIG. 1 is a front view showing an example of the rail unit 2. In addition, the up-down direction of FIG. 1, a longitudinal direction, and a paper surface depth direction are the up-down direction of the rail unit 2, a longitudinal direction, and the left-right direction.

  A rail unit 2 shown in FIG. 1 is a straddle-type bogie rail unit, and has a single rail 21 and a lower frame 22 having a circular cross section and a single rail 21 and a lower frame 22 arranged in parallel in a vertical direction at a predetermined distance. A plurality of vertical members 23 provided at predetermined intervals in the longitudinal direction between the vertical members 23, a plurality of diagonal members 24 provided in a “C” shape between the vertical members 23 and 23, and both longitudinal ends There are two columnar fixed support portions 25 provided in parallel with the single rail 21 at the center in the vertical direction across the vertical member 23 on the side and the diagonal member 24 adjacent to the vertical member 23. In the present embodiment, the vertical member 23 and the diagonal member 24 constitute a connecting member in the present invention. The main material of these members constituting the rail unit is a metal material. Specifically, stainless steel is preferably used. The length of the rail unit 2 in the longitudinal direction is usually about 4 m to 6 m. A single rail 21 is constructed by connecting a plurality of rail units 2 in the longitudinal direction.

(Straddle-type trolley)
Next, a straddle-type cart (hereinafter, sometimes referred to as “cart”) that moves over the single rail 21 will be described. The schematic block diagram of the trolley | bogie 1 is shown in FIG.2 and FIG.3. FIG. 2 is a front view of the carriage 1 straddling the single rail 21, and FIG. 3 is a cross-sectional view taken along line AA in FIG. The carriage 1 includes two motors M <b> 1 and M <b> 2 before and after the traveling direction in the housing 11. As shown in FIG. 3, in the housing 11, three driving wheels 12 a, 12 b, 12 c that are supported by the housing 11 and are pressed against the outer periphery of the single rail 21 at equal intervals in the circumferential direction, and bearings 56 a, 56 b. And holding plates 57a and 57b, respectively, and compression coil springs 14a and 14b for urging the drive wheel 12b and the drive wheel 12c in the direction of the single rail 21, respectively.

  Further, the carriage 1 has a circumferential center position between the driving wheel 12a and the driving wheel 12b (position facing the driving wheel 12c and the single rail 21) and a circumferential center between the driving wheel 12a and the driving wheel 12c. Further, driven wheels 16a and 16b that come into contact with the single rail 21 and roll are provided at positions (positions that face the drive wheel 12b across the single rail 21). The driven wheels 16a and 16b may be in pressure contact with the single rail 21 by urging means, or may simply be in contact. By providing the driven wheels 16a and 16b in this manner at the opposing positions of the drive wheels 12b and 12c that are pressed against the single rail 21 by the compression coil springs 14a and 14b, respectively, a hollow columnar one is used as the single rail 21. Even in such a case, the deformation of the cross-sectional shape of the single rail 21 is effectively prevented. The mounting position of the driven wheels 16a, 16b is not particularly limited as long as it is between the driving wheels 12a, 12b and between the driving wheels 12a, 12c. From the viewpoint of preventing the cross-sectional shape of the single rail 21 from being deformed, A position facing the wheel across the single rail 21 is desirable.

  The driving force of the motor M1 is transmitted from the driving shaft (not shown) of the motor M1 to the rotating shaft 52 in the gear box 51, and the driving wheel 12a and the bevel gears 53a and 53b rotate. The driving force is transmitted to the rotating shaft 55a by the engagement of the bevel gear 53a and the bevel gear 54a, and the driving wheel 12b rotates. Similarly, the driving force is transmitted to the rotary shaft 55b by the meshing of the bevel gear 53b and the bevel gear 54b, and the drive wheel 12c rotates. The other drive unit by the motor M2 has the same configuration.

  The driving wheel 12b and the driving wheel 12c are urging forces of the compression coil springs 14a and 14b, and the driving wheel 12a is in pressure contact with the single rail 21 by its own weight. In addition, since the pressure contact positions of the single rails 21 of the three drive wheels 12a, 12b, 12c are equally spaced in the circumferential direction, the frictional force between the drive wheels 12a, 12b, 12c and the single rail 21 is large, and the carriage 1 efficiently travels on the single rail 21 and has high climbing ability. In addition, since the carriage 1 includes two drive units in the front-rear direction, for example, heavy materials such as forest road construction materials and equipment and felled wood can be transported. It has been confirmed that the prototype device created by the present inventor can carry up to 200 kg so far. Furthermore, since the horizontal position of the carriage 1 is determined by the pair of sliding members 17a and 17b, the movement of the carriage 1 around the single rail 21 during traveling can be suppressed. The load by the compression coil springs 14a, 14b is usually preferably about several thousand N, more preferably 4000 N or more.

(First embodiment)
The installation method of the rail unit 2 of this invention is demonstrated using FIGS. First, as shown in FIG. 4, a support pile 31 is driven into an inclined surface such as a forest. The driving angle θ with respect to the inclined surface of the support pile 31 is in the range of 20 ° to 45 ° in the lower direction of the inclined surface with respect to the vertical direction. By setting the driving angle θ within this range, the rail unit 2 can be firmly supported by the support pile 31 even when a heavy object such as felled wood is transported on the carriage 1. Usually, it is desirable to increase the driving angle θ of the support pile 31 as the inclination of the inclined surface becomes steeper.

  What is necessary is just to determine suitably the thickness of the support pile 31 to be used, the length, a material, etc. from the weight etc. of the articles | goods carried on the trolley | bogie 1 and conveyed. For example, when carrying heavy objects such as fallen timber with the carriage 1, a single pipe having a length of about 1 m to 2 m and a thickness (outer diameter) of about 4 cm to 8 cm is preferably used. Of course, a log pile or the like may be used, but a single pipe is preferable in consideration of the efficiency of pile driving work. Regarding the driving depth of the support pile 31, the deeper the stability of the support pile 31 is, the more time and labor are required for the pile driving work. Further, time and labor are required for the withdrawal operation, that is, the extraction operation of the support pile 31. According to the experiments by the present inventors, it has been found that even if a heavy object is transported by the carriage 1 with a normal driving depth of about 10 cm to 20 cm, depending on the soil quality, depending on the soil quality. In the case of soil quality such as wetlands, it is necessary to stake deeper.

  Next, as shown in FIG. 5, the lower frame 22 of the rail unit 2 is connected to the support pile 31 driven into the inclined surface at a predetermined angle. Although there is no limitation in particular in the connection position of the lower frame 22 with respect to the support pile 31, from the viewpoint of supporting the rail unit 2 stably, it is desirable to connect below the support pile 31, ie, the vicinity of an inclined surface. When a single pipe is used as the support pile 31, a commercially available clamp 34 can be used for connection between the support pile 31 and the lower frame 22. However, the connection between the support pile 31 and the lower frame 22 requires that the rail unit 2 can swing around the lower frame 22.

  Then, the rail unit 2 is swung around the central axis of the lower frame 22 so that a plane including the central axis of the single rail 21 and the central axis of the lower frame 22 is in a vertical state parallel to the vertical direction. adjust. The adjustment of the vertical state of the rail unit 2 may be performed using a bubble tube level, for example.

  Next, as shown in FIG. 6, one end of the angle adjustment member 32 in the form of a single pipe is connected to the fixed support portion 25 of the rail unit 2 adjusted to a vertical state, and the other end of the angle adjustment member 32 is connected. An end part is connected to the support pile 31, and the rail unit 2 is fixed in a vertical state. The fixing position of the rail unit 2 and the support pile 31 by the angle adjusting member 32 is an upper position than the connection position of the support pile 31 and the lower frame 22. Further, when connecting the angle adjusting member 32 and the fixed support portion 25 of the rail unit 2 and connecting the angle adjusting member 32 and the support pile 31, a single pipe is used as the angle adjusting member 32 and the support pile 31. Can use a commercially available clamp 34.

  Before adjusting the rail unit 2 to the vertical state, at least one of the fixed support portion 25 and the support pile 31 and the angle adjusting member 32 are connected weakly in advance so that the angle adjusting member 32 can be inserted and removed. After adjusting to a vertical state, the loosely connected portion may be strongly connected so that it cannot be inserted or removed.

  As shown in FIG. 7, when the angle of the inclined surface is steep, the auxiliary pile 33 is driven in the vertical direction in the vicinity of the support pile 31, and the auxiliary pile 33 and the support pile 31 are connected to each other. The support of the rail unit 2 may be reinforced. Specifically, the auxiliary pile 33 is driven into the ground after the lower end of the auxiliary pile 33 is inserted through the through hole 351 of the settlement suppression plate 35. Then, the subsidence suppression plate 35 is brought into contact with the ground, and a stopper 36 is attached to a portion directly above the subsidence suppression plate 35 of the auxiliary pile 3. The inner diameter of the through hole 351 formed in the settlement suppression plate 35 is set to be larger than the outer diameter of the auxiliary pile 33 and smaller than the outer diameter of the stopper 36. Thereby, the force applied to the subsidence direction of the auxiliary pile 33 to the ground is applied to the subsidence suppression plate 35 via the stopper 36, and the subsidence of the auxiliary pile 33 to the ground is suppressed. The connection position between the auxiliary pile 33 and the support pile 31 is preferably the upper end portion of the support pile 31. As the auxiliary pile 33, similarly to the support pile 31, a single pipe is preferably used. When using a single pipe as the auxiliary pile 33 and the support pile 31, a commercially available clamp can be used as a connection member. As in the case of the support pile 31, the driving depth of the auxiliary pile 33 is usually about 10 cm to 20 cm from the viewpoint of the time and labor of pile driving work and withdrawal work (drawing work), the strength of reinforcement, and the like.

  FIG. 8 is a perspective view when the rail unit 2 is installed by the installation method of the present invention described above. The rail unit 2 has a length of about 4 m to 6 m in the longitudinal direction, and a single rail 21 on which the carriage 1 moves is constructed by connecting the rail units 2 continuously in the longitudinal direction. FIG. 8 shows the longitudinal end of the rail unit 2 under construction. When the next rail unit 2 is extended in the longitudinal direction, the single rails 21 and the lower frames 22 of the rail unit 2 are straightened. Connect using a joint. And the longitudinal direction front-end | tip part of the extended rail unit 2 is fixed to a perpendicular state by the method of the said this invention. By repeating this operation, the rail unit 2 can be installed from a predetermined position to a desired position.

  In order to bridge and fix the belt-like band 4 between the existing object in the vicinity of the support pile 31 and the rail unit 2 in a tensioned state, means usually used for packing or the like can be used. That is, the belt-like band 4 is wound around the existing object and the rail unit 2 to form a ring-like shape, and both ends in the longitudinal direction of the belt-like band 4 are inserted and overlapped from the opposed openings of the flat rectangular column-shaped metal band seal. To do. Then, after the belt-like band 4 is tightened to be in a tensioned state, the band seal is pressed and deformed by a sealing machine to bind both ends in the longitudinal direction of the belt-like band 4.

  It should be noted that since a banding band 4 using such a band seal requires a sealing machine or a tightening machine, workability on an inclined surface may be reduced. Therefore, the inventor of the present invention newly invented a fixing tool that adjusts the belt-like band 4 having a predetermined length into a ring shape having a desired circumferential length and fixes it in a tensioned state. This fixture will be described later.

It should be noted that at least one through-hole is sufficient for binding and length adjustment at both ends in the longitudinal direction of the band 4.

  FIG. 16 illustrates a method for fixing the belt-like band 4 using the fixture 6 having such a structure. As shown in FIG. 16 (a), both ends of the band-like band 4 extending between the existing object or the anchor member 5 and the rail unit 2 are inserted from both sides of the through-hole 621 of the columnar member 62, and penetrated. In the hole 621, both longitudinal ends of the band 4 are overlapped.

  Next, as shown in FIG. 16 (b), the belt 6 is wound around the outer periphery of the columnar member 62 by rotating the fixture 6, and the circumferential length of the annular band 4 is reduced. Since the band 4 made of polypropylene has deformation resistance, a large force is required to rotate the fixture 6 until the band 4 is in tension. For this reason, it is preferable to rotate the fixture 6 by engaging a tool such as a ratchet handle with the hexagonal column-shaped shaft portion 64 (shown in FIG. 13).

  As shown in FIG. 16 (c), the fixing device 6 is further rotated to narrow the circumferential length of the belt-like band 4 that is bridged between the existing member or the anchor member 5 and the rail unit 2 to form a belt-like band. 4 is under tension.

  Then, as shown in FIG. 16 (d), the rotation preventing member 65 (shown in FIG. 13) is inserted into the fixing holes 63 a and 63 c that are symmetrical with respect to the axis of the columnar member 62. The band 4 made of polypropylene has deformation resistance, and the band 4 wound around the outer periphery of the columnar member 62 of the fixture 6 extends the circumference of the band 6 in order to return to the original state. Although it tries to reversely rotate (clockwise in FIG. 16), reverse rotation of the fixture 6 is prevented by the rotation stop member 65 (shown in FIG. 13) inserted through the fixing holes 63a and 63c. Thereby, the belt-like band 4 is fixed in a tensioned state.

  In addition, when releasing fixation of the strip | belt-shaped band 4 by the fixing tool 6, the rotation prevention member 65 is pulled out from the fixing holes 63a and 63c, and the fixing tool 6 is reversely rotated. As a result, the belt-like band 4 is unwound from the columnar member 62 and the fixation of the belt-like band 4 is released.

  A fixing hole is formed in the pair of plate-like members 61 a and 61 b at a position radially outward from the outermost periphery of the band 4 wound around the columnar member 62, that is, an outer edge position, with the axis of the columnar member 62 as the center. It should be a symmetric position. Moreover, it is preferable that the fixing tool 6 is formed at equal intervals in the rotation direction. In addition, the number of fixing holes may be two or more. As the number of fixing holes is increased, the tension generated in the belt-like band 4 can be finely adjusted. However, the strength of the pair of plate members 61a and 61b may be reduced. The number is preferably determined in consideration of the material of the pair of plate-like members 61a and 61b, the inner diameter of the fixing hole, and the like.

(Fixing tool 6: Second embodiment)
FIG. 17 is a view showing a second embodiment of the fixture 6 and is a cross-sectional view corresponding to FIG. 15. The difference between the fixture 6 shown in this figure and the fixture 6 shown in FIGS. 14 and 15 is the structure of the columnar member. In the fixture 6 shown in FIG. 17, the columnar member is composed of four rod-shaped members 66. As shown by the alternate long and short dash line in FIG. 17, the four rod-shaped members 66 are arranged so that the center of each axis is the apex position of the quadrangle, and both longitudinal ends of the belt-like band 4 overlap between the rod-shaped members 66. A gap d that can be inserted is formed. These gaps d constitute the through holes of the present invention. The cross-sectional shape and thickness perpendicular to the axial direction of the rod-shaped member 66 are not particularly limited, and may be determined as appropriate based on the width and thickness of the band 4 to be used. A metal material such as iron or stainless steel is desirable as the material of these rod-like members 66, and the attachment of the rod-like member 66 to the pair of plate-like members 61a and 61b is desirably performed by a strong joining method such as welding or screwing. .

  According to the rail unit installation method of the present invention, the rail unit 2 can be brought into a vertical state and fixed to the support pile with less time and effort.
