  FIG. 1 is a perspective view for explaining the configuration of the unloading device 1. FIG. 2 is a side view of the vicinity of the main body 10 of the unloading device 1. The unloading device 1 mainly includes a main body 10, a loading platform 20, a winch 30, and ropes 40 and 40.

  One end of the two ropes 40 is connected to the loading platform 20, and the other end of the two ropes 40 is wound around a drum 31 (detailed later) of the winch 30. When the two ropes 40 are simultaneously wound up by the winch 30, the loading platform 20 is lifted from the state where it is placed on the ground (the state shown in FIG. 1), and when the loading platform 20 is lifted to the position of the body unit 10, 10 is lifted to the roof 102 (about 10 to 15 m in height) of the building (see FIG. 2).

  As shown in FIG. 1, the main body 10 has two rails 11. The two rails 11 are attached to the upper end of the wall 101 of the building 100 in parallel (including a minute error) at a predetermined interval (can be arbitrarily set).

  FIG. 2 is a side view of the rail 11. The rail 11 is J-shaped and has a short side 11a and a long side 11b via a curved portion. The J-shape includes a case where the short side 11a and the long side 11b are parallel to each other, and a case where the short side 11a and the long side 11b have an error of several degrees, etc. It is a concept that includes.

  A mounting member 12 is provided on the long side 11 b of the rail 11. The attachment member 12 mainly includes a leg 12a, an adjustment member 12b, and a fixing portion 12c.

  The leg 12a is fixed to the rail 11 so as to be vertically downward when the rail 11 is attached to the wall 101. An adjustment member 12b is screwed to the tip of the leg 12a.

  The fixing portion 12c is provided at the tip of the adjustment member 12b (the curved side of the rail 11). By rotating the adjusting member 12b, the relative positional relationship between the adjusting member 12b and the fixing portion 12c and the leg 12a is adjusted, and the fixing portion 12c is brought into contact with the wall 101. Thereby, the wall 101 is clamped by the tip of the short side 11a and the fixing portion 12c, and the rail 11 is fixed to the wall 101 so that the long side 11b of the rail 11 crosses the upper side of the upper end of the wall 101.

  A leg 13 is provided at the tip of the long side 11b of the rail 11 via adjustment mechanisms 13a and 13b. The adjusting mechanisms 13a and 13b adjust the length of the leg 13 and the angle between the long side 11b and the leg 13 so that the tip of the leg 13 contacts the rooftop 102.

  A plurality of pulleys 15 (15A, 15B, 15C, 15D, 15E) are provided on the long side 11b of the rail 11. The rope 40 wound around the winch 30 is connected to the loading platform 20 via the pulley 15 in the order of the pulley 15A, the pulley 15B, the pulley 15C, the pulley 15D, and the pulley 15E.

  The arrangement of the pulley 15 will be described. 3A and 3B are enlarged views of the main part 10 for explaining the arrangement of the pulleys 15A and 15B. FIG. 3A is a plan view (viewed from above in FIG. 2), and FIG. It is AA sectional drawing of).

  The pulley 15A has two pulleys 15A-1 and 15A-2. The two pulleys 15A-1 and 15A-2 are pivotally supported by the rail 11 so that the axis is orthogonal to the rail 11 and the disk is parallel to the rail. The two pulleys 15A-1 and 15A-2 are provided on the rail 11 so that the disks are separated by a predetermined distance d. Here, the predetermined distance d can be arbitrarily set according to the winding width of the rope 40 in the drum 31 (detailed later) of the winch 30.

  The pulley 15A is provided at a position where an axis D between the drum 31 of the winch 30 (detailed later) and the pulley 15A is separated by a distance of about 10 times the diameter of the drum 31 of the winch 30. In the present embodiment, since the diameter of the drum 31 is about 100 mm, the axis D between the drum 31 (detailed later) and the pulley 15A is about 1 m. The distance between the pulley 15A and the drum 31 only needs to be about 10 times or more, and is not limited to about 10 times. Moreover, about 10 times is a concept including an error of about 1 time which is limited to 10 times.

  The pulley 15B has two pulleys 15B-1 and 15B-2 that form a pair. The two pulleys 15B-1 and 15B-2 are pivotally supported adjacent to the rail 11 so that the axis is orthogonal to the rail 11 and the disk is parallel to the rail. Further, the pulley 15B is provided at the tip (including the vicinity of the tip) of the long side 11b of the rail 11.

  In the present embodiment, a rod is provided between the two rails 11 and the pulleys 15A and 15B are provided on the rod. However, the method of providing the pulleys 15A and 15B on the rail 11 is not limited to this.

  Since the pulleys 15C, 15D, and 15E have substantially the same structure as the pulley 15B, description thereof is omitted.

  A winch attachment portion 14 is attached to the leg 13. A winch 30 is attached to the winch attachment portion 14. FIG. 4 is a perspective view of the main part of the winch 30 seen through. In FIG. 4, the see-through portion is indicated by a dotted line.

  The winch 30 is a so-called electric winch, and mainly includes a drum 31, an actuator 32, a transmission unit 33, and a housing 34.

  The drum 31 is rotatably supported by the housing 34. The drum 31 is provided outside the housing 34. The drum 31 is divided into two regions 31b and 31c in the longitudinal direction by a flange 31a. Separate ropes 40 and 40 are wound around the two regions 31b and 31c, respectively.

  The actuator 32 is provided inside the housing 34 so that the output shaft 32a is parallel to the shaft 31d of the drum 31 (indicated by a broken line because it cannot be seen in FIG. 4).

  The transmission unit 33 has a plurality of gears and transmits the output of the actuator 32 to the shaft of the drum 31. A pinion 33a is press-fitted into the output shaft 32a. The output of the output shaft 32a is transmitted to the gear 33d press-fitted into the shaft 31d of the drum 31 via the pinion 33a and gears 33b and 33c.

  An opening 34 a is formed in the housing 34. The output shaft 32a is exposed through the opening 34a. The drum 31 can be rotated (only in the direction of rewinding the rope 40) by manually rotating the output shaft 32a from the outside of the housing 34 using a jig or the like. Thereby, even when the winch 30 stops due to a problem or the like, the loading platform 20 can be lowered.

  The other end of the rope 40 wound around the drum 31 is connected to the loading platform 20 via the pulley 15. 5A and 5B are diagrams showing the loading platform 20, in which FIG. 5A is a side view and FIG. 5B is a front view.

  The loading platform 20 includes a back surface portion 21, a bottom surface portion 22, a tire 23, a rope hooking portion 24, a front surface portion 25, and a guide portion 26.

  The back surface portion 21 is a substantially rectangular plate-like member, and the width (FIG. 5B, left-right direction) is substantially the same as the interval between the two rails 11.

  Mounting portions 21 a and 21 b for mounting the bottom surface portion 22 are provided on the front surface side of the back surface portion 21. The attachment portions 21a and 21b are provided so that the positions in the height direction are different in the state where the loading platform 20 is lifted (the state shown in FIG. 5). In addition, you may comprise the back part 21 so that it may become plate shape by combining several pillars.

  A tire 23 that can run on the rail 11 is rotatably supported on the back side of the back portion 21. The width between the tires 23 (the left-right direction in FIG. 5B) is the same as the width of the two rails 11. In the present embodiment, four tires 23 are provided, but the number of tires 23 is not limited to this.

  A rope hooking portion 24 that connects the rope 40 is provided on the back side of the back surface portion 21. The rope hooking portion 24 is provided on the center line (including an error of several centimeters) in the width direction of the back surface portion 21 (left and right direction in FIG. 5B). Two ropes 40, 40 are adjacently connected to the rope hook 24.

  The bottom surface portion 22 is a table for placing a load such as a solar panel, and is a substantially rectangular plate-shaped member. A front surface portion 25 for holding a load is provided on the front surface of the bottom surface portion 22.

  A guide portion 26 is provided on the front surface portion 25. The guide portion 26 is a rod-like member whose length is longer than the width of the back surface portion 21. Pulling ropes 41 and 41 for adjusting the attitude of the loading platform 20 are connected to both ends of the guide portion 26.

Next, the operation of the unloading device 1 configured as described above will be described.
First, a luggage such as a solar panel is placed on the loading platform 20 placed on the ground. The ropes 40 and 40 wound around the drum 31 of the winch 30 are connected to the rope hooking portion 24 of the loading platform 20 via the pulley 15.

  The winch 30 is driven to wind the two ropes 40 around the drum 31 simultaneously. In this embodiment, since the two ropes 40 are used, even if the rope 40 is cut, the remaining one rope 40 can lift the cargo bed 20, so that the cargo bed 20 falls or the like. Accidents can be prevented. In particular, in the present embodiment, it is assumed that a heavy load (about 130 kg) such as a solar panel is lifted. Therefore, safety must be given top priority. By using the two ropes 40, safety can be improved.

  Since the two ropes 40, 40 are both wound around different regions 31b, 31c of the same drum 31, the two ropes can be wound up simultaneously. Further, since the two ropes 40, 40 are wound up by the same drum 31, the lifting force (load resistance) and the lifting speed are not changed even when only one rope 40 is used. Further, since the two ropes 40, 40 are wound up by the same drum 31, when the winch 30 can shift the winding speed in two steps, the two-step shifting can be supported.

  The worker on the ground adjusts the posture of the loading platform 20 with the pulling rope 41. Since the guide portion 26 connected to the pulling rope 41 is longer than the width of the back surface portion 21, the posture of the loading platform 20 can be easily adjusted with a small force.

  When the rope 40 is continuously wound around the drum 31, as shown in FIG. 2, the tire 23 of the loading platform 20 comes into contact with the rail 11, and the loading platform 20 is raised upward along the rail 11.

  The pulley 15A has a distance D to the drum 31 (see FIG. 3) that is about 10 times the diameter of the drum 31, and the two pulleys 15A-1 and 15A-2 are spaced apart (not adjacent to each other). Thus, the two ropes 40 can be wound up in a state of being neatly aligned with the respective wound regions 31b and 31c (without being disturbed). If the rope 40 becomes turbulently wound, the life of the rope 40 is greatly reduced, and the risk of dropping the loading platform 20 due to the cutting of the rope 40 is increased. On the other hand, in this Embodiment, since the rope 40 does not become turbulent winding, the lifetime of the rope 40 can be lengthened and safety | security can be improved.

When the loading platform 20 comes near the tip of the long side 11b of the rail 11, the winch 30 is stopped and the loading platform 20 is stopped. As a result, the luggage is raised to the rooftop 102.
When the load is unloaded from the loading platform 20 on the rooftop 102, the winch 30 is rotated and the rope 40 is rewound. Thereby, the loading platform 20 is lowered to the ground.

  When the load is a plate-like member such as a solar panel, as shown in FIG. 5, the bottom portion 22 is attached to the attachment portion 21a. However, when the load is a rod-like member, the bottom portion is attached to the attachment portion 21b. The part 22 is attached. In this way, by adjusting the height of the bottom surface portion 22 according to the shape of the luggage, it is possible to safely raise objects of various shapes.

According to the present embodiment, the main body 10 is not formed in a ladder shape, the main body 10 is attached only to the upper end of the wall 101, and the loading platform 20 is lifted by the two ropes 40. Luggage can be safely lifted up to the rooftop of about 10-15m in height.
Moreover, according to this Embodiment, since it was set as the structure which can wind up two ropes without making a turbulent winding, safety | security can be improved more.

  In addition, in this Embodiment, although the main-body part 10 was attached to the upper end part of the wall 101 of a building, you may attach to the opening part (for example, window) of the wall 101. FIG. In this case, the rail 11 should just be fixed to the wall 101 so that the long side 11b of the rail 11 may cross the upper side of the bottom face of an opening part.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included. .
