  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a purse work device according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a straddle-type work monorail vehicle 1 (hereinafter, simply referred to as “monorail vehicle”) provided with a underarm working device according to the present invention. As shown in the figure, a monorail vehicle 1 includes a main body 2, a pair of left and right legs 3a, 3b extending downward from the main body 2, and a front running wheel driven by electric power stored in a battery. 4a, 4b, the rear traveling wheels 5a, 5b that are only driven, the front guide wheels 6a, 6b and the rear guide wheels 7a, 7b that sandwich the upper part of the beam 100 from the left and right, and the lower part of the beam 100 from the left and right. Front stabilizer wheels 8a and 8b and rear stabilizer wheels 9a and 9b are provided. The traveling wheels 4a, 4b, 5a, 5b are disposed between the leg portions 3a, 3b. The guide wheels 6a and 7a and the stabilizing wheels 8a and 9a are disposed on the leg 3a. Further, the guide wheels 6b and 7b and the stabilizing wheels 8b and 9b are disposed on the leg portion 3b. FIG. 1 does not show some wheels (5b, 7b, 9b).

  The monorail vehicle 1 further includes elevators 10a and 10b having the same configuration. As shown in the figure, the elevator 10a is provided on the leg 3a, and the elevator 10b is provided on the leg 3b. The underarm working device according to the present invention includes these two elevators 10a and 10b.

  The elevator 10a can take the accommodation position (refer FIG. 1) accommodated in the leg part 3a, and the working position (refer FIG. 2) lowered | hung from the leg part 3a. The elevator 10b can also take the accommodation position (refer FIG. 1) accommodated in the leg part 3b, and the operation | work position (refer FIG. 2) lowered | hung from the leg part 3b. When the first deployable floor plate 20 and the second deployable floor plate 30 included in each of the elevators 10a and 10b are deployed after the elevators 10a and 10b are moved to the working position, as shown in FIG. A floor (work table) that allows free passage between the elevator 10 a and the elevator 10 b is formed below the beam 100. The operator moves from the main body 2 to the work table through the legs 3a and 3b, and sufficiently performs the work under the girder (inspection of the girder 100 and the duct 101 provided on the lower surface of the girder 100). And can be done safely. The first deployable floor plate 20 and the second deployable floor plate 30 will be described in detail later.

  As shown in FIG. 3, the elevator 10 b includes wall plates 12 a and 12 b erected on each of three sides excluding a floor plate 11 having a rectangular shape in plan view and an open side 11 a that is one side of the floor plate 11 near the beam 100. , 12c. When the elevator 10b is in the storage position, the floor board 11 is substantially the same height as the lower end of the leg 3b (see FIG. 1). On the other hand, when the elevator 10b takes the working position, the floor board 11 is below the lower end of the leg 3b (see FIG. 2).

  As is clear from the figure, a part of the wall plate 12a (12c) is cut away. This is to avoid contact with the duct 101 provided on the lower surface of the beam 100. This contact problem will be described with reference to FIG.

  In a monorail, two girders 100 are usually used to simultaneously drive monorail vehicles that run in opposite directions. And the duct 101 is provided in the lower surface of each girder 100 in most driving | running | working areas (refer the figure (B)). However, in the section where the beam column 102 exists, the duct 101 is arranged at a position shifted from directly below the beam 100 (see FIG. 3C). Therefore, if the notch is not provided in the wall plate 12a (12c), the monorail vehicle 1 cannot approach the beam column 102 while moving the undergrowth work device (elevators 10a and 10b) to the work position. . In other words, in the monorail vehicle 1 according to the present invention, the wall plate 12a (12c) is provided with a notch, so that the beam column 102 is moved while the undergrowth work devices (elevators 10a and 10b) are moved to the work position. Can approach. Then, it is possible to inspect the beam column 102 up close.

  Refer to FIG. 3 again. The elevator 10b further includes a first deployable floor plate 20 having a rectangular shape in plan view, a pair of mounting members 21a and 21b, and a pair of fall prevention walls 23a and 23b.

By this rotation, the first deployable floor board 20 takes an upright position (see FIG. 3A) rising from the floor board 11 and an unfolded position (see FIG. 3B) that continues with the floor board 11. be able to. When the first deployable floor plate 20 is in the unfolded position, the first rotation reference side 20 a of the first deployable floor plate 20 abuts on the open side 11 a of the floor plate 11.

  The fall prevention walls 23 a and 23 b are erected on two sides orthogonal to the first free side 20 b of the first deployable floor plate 20. The first deployable floor plate 20 and the fall-preventing walls 23a and 23b are dimensioned so that they do not protrude from the cutout portions of the wall plate 12a (12c) when the first deployable floor plate 20 is in the upright position. Yes. This is because the meaning of providing a notch is lost.

  Although not shown in FIG. 3, the elevator 10 b further includes a manual winch mechanism. The main body portion of the manual winch mechanism is provided in a space surrounded by the wall plates 12a, 12b, and 12c, and the tip of the wire extending from the main body portion is connected to the deployable floor plate 20. When the operator operates the manual winch mechanism so that the wire is pulled out, the first deployable floor board 20 takes the deployed position. On the other hand, if an operator operates a manual winch mechanism so that a wire may be wound up, the 1st expandable floor board 20 will take an upright position.

  As shown in FIG. 5, the elevator 10 b further includes a lid plate 13 having a rectangular shape in plan view and made of an elastic material such as rubber, and a hinge 14. The hinge 14 has a rotation shaft 15 parallel to the open side 11a. The hinge 14 has one side fixed to the floor plate 11 and the other side to which the lid plate 13 is attached is a free end. It can also be said that the cover plate 13 has a third rotation reference side parallel to the open side 11a, and the third rotation reference side is rotatably attached in the vicinity of the open side 11a.

  When the first deployable floor plate 20 is in the upright position, the lid plate 13 is supported by the first deployable floor plate 20 and takes the upright position rising from the floor plate 11 (see FIG. 5A). Moreover, when the 1st expandable floor board 20 has taken the expansion | deployment position, the cover board 13 covers the boundary of the floor board 11 and the 1st expandable floor board 20 which continued (refer the same figure (B)). Thereby, the fall of the tool etc. from the clearance gap between the floor board 11 and the 1st expandable floor board 20 can be prevented reliably. In addition, the arrow t20 in the figure (A) shows the rotation locus | trajectory of the 1st expandable floor board 20 centering on the rotating shaft 22, and arrow t13 shows the lid | cover body 13 centering on the rotating shaft 15. FIG. The rotation trajectory is shown.

  As shown in FIG. 6, the elevator 10 b further includes a second deployable floor plate 30 having a rectangular shape in plan view smaller than the first deployable floor plate 20 and a hinge 32. The hinge 32 has a rotating shaft 33 parallel to the open side 11a. Further, the hinge 32 has one side fixed to the first deployable floor plate 20 and the other side to which the second deployable floor plate 30 is attached is a free end. The second deployable floor plate 30 has a second rotation reference side 30a parallel to the open side 11a and a second free side 30b opposite to the second rotation reference side 30a, and the second rotation reference side 30a is the first free side 20b. It can also be said that it is pivotably attached in the vicinity.

  As shown in FIG. 6, the 2nd expandable floor board 30 is further provided with the tongue piece 31 of the planar view rectangular shape which consists of elastic materials, such as rubber | gum provided in the 2nd free side 30b.

  The second deployable floor board 30 can take a storage position folded on the first deployable floor board 20 and a deployment position that continues with the first deployable floor board 20. When the first deployable floor plate 20 and the second deployable floor plate 30 of the elevators 10a and 10b are deployed, the second free side 30b of the second deployable floor plate 30 on the elevator 10b side is the elevator as shown in FIG. The second free side 30b of the second deployable floor plate 30 on the elevator 10a side is close to the first free side 20b of the first deployable floor plate 20 on the 10a side, and the first deployable floor plate 20 on the elevator 10b side is first. Proximity to the free side 20b. At this time, the tongue piece 31 on the elevator 10b side covers a part of the first deployable floor plate 20 on the elevator 10a side, and the tongue piece 31 on the elevator 10a side is a part of the first deployable floor plate 20 on the elevator 10b side. Cover the part. Thereby, the fall of the tool etc. from the clearance gap between the 1st expandable floor board 20 and the 2nd expandable floor board 30 can be prevented reliably.

  The operator can manually change the position of the second deployable floor plate 30 from the accommodated position to the deployed position, or from the deployed position to the accommodated position.

  As apparent from FIG. 7, the length L20b of the first free side 20b of the first deployable floor plate 20 on the elevator 10b side is the length L20a of the first free side 20b of the first deployable floor plate 20 on the elevator 10a side. be equivalent to. Further, the sum of the length L30b of the second free side 30b of the second deployable floor plate 30 on the elevator 10b side and the length L30a of the second free side 30b of the second deployable floor plate 30 on the elevator 10a side is the first. The length L20b (= L20a) of the first free side 20b of the deployable floor plate 20 is substantially equal. Furthermore, in this embodiment, the length L30a and the length L30b are also equal.

  As shown in FIG. 8, a door 40 that is rotatably attached via a hinge 41 is provided on the inner surface of the fall prevention wall 23 b of the elevator 10 a. In addition, a connecting tool 42 for gently connecting the door 40 and the fall prevention wall 23a is provided on the inner surface of the fall prevention wall 23a of the elevator 10b. The same applies to the inner surface of the fall prevention wall 23a of the elevator 10a and the inner surface of the fall prevention wall 23b of the elevator 10b. By filling the gap between the fall prevention walls 23a and 23b with the door 40, the operator can be prevented from falling.

  The state shown in FIG. 1 (that is, the elevators 10a and 10b take the storage position, the first deployable floor plate 20 of each elevator 10a and 10b takes the upright position, and the second deployable floor plate 30 of each elevator 10a and 10b has The state shown in FIG. 2 (that is, the elevators 10a and 10b take the working position from the storage position), and the first deployable floor plate 20 and the second deployable floor plate 30 of each elevator 10a and 10b are deployed.
