Lifting device

Abstract

To provide a lifting device of a novel structure.SOLUTION: A suspension root part 30 of a lifting device 100 comprises: a base member 70; a rotation support member 80 (rotation mechanism, moving mechanism); and a rotation member 90 (moving member). The rotation support member 80 enables the rotation member 90 to rotate relative to the base member 70. The rotation member 90 is rotatable (movable) so that its tip (specific part) can be positioned on both the indoor side (arrow A, inside building 10) and the outdoor side (arrow B, outside building 10) of the building 10. By installing the suspension root part 30 in two locations on the roof, lifting and movement of the entire wall surface becomes possible. Since all installation operations can be performed on the indoor side of the roof, dangerous aerial work, high-place work vehicles, and construction machines such as cranes become unnecessary, enabling safe and simple installation. A heavy object can be lifted and moved to accurate coordinates by using a winder-type winding device while using a wire as a suspension tool.SELECTED DRAWING: Figure 2

[0047] [First embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a diagram showing a lifting device 100 of a first embodiment. In this specification, when looking at a building 10 in Fig. 1 from the front, the left side is the -X direction, the right side is the +X direction, the lower side is the -Y direction, the upper side is the +Y direction, the front side is the -Z direction, and the rear side is the +Z direction.

[0048] As shown in FIG. 1, the lifting device 100 is a device that lifts a working robot (an object to be lifted) along a wall surface 11 of a building 10. The building 10 is provided with an installation section 12 (e.g., a parapet) on the rooftop where the lifting device 100 is installed. The lifting device 100 is a device that can move the working robot up, down, left and right on the building wall surface and is easy to install on the building. The working robot is a device that performs work on the wall surface of a building. In this embodiment, a window cleaning robot 20 that cleans windows arranged on the wall surface 11 of the building 10 will be described as an example of a working robot.

[0049] The lifting device 100 comprises a hanging unit 30, a wire 40 (stretching member, hanging tool), a hanging unit 50, and a power unit 60. The hanging units 30 are installed (fixed) in two locations, one on each end of the roof of the building 10, and wires 40 are extended from each unit and connected to the window cleaning robot 20 (hanging units 50). The left and right wires 40 are wound up to lift and move the window cleaning robot 20 up, down, left and right. The hanging unit 30 is a member that supports the window cleaning robot 20, the wire 40, the hanging unit 50, etc., and fixes the lifting device 100 to the rooftop.

[0050] The wire 40 is a member stretched between at least two hanging parts 30, and connects the hanging parts 30 and the window cleaning robot 20. In this embodiment, the wire 40 is stretched between the upper left power unit 60, the upper left hanging part 30, the hanging part 50, the upper right hanging part 30, and the upper right power unit 60. The wire 40 is a member that suspends the window cleaning robot 20 via the hanging parts 50.

[0051] The wire 40 is a linear or belt-like member. The wire may be a chain or a rope. The wire 40 can be changed to another member as appropriate depending on the weight and use of the lifted object. The type of member to be selected for the wire 40 can be determined by taking into consideration the conditions of the installation location. A plurality of wires 40 may be arranged in parallel in the depth direction. This makes it possible to prevent the window cleaning robot 20 from falling even if one of the wires 40 breaks for some reason.

[0052] The hanging part 50 is movably suspended by the wire 40 between the two hanging parts 30, and is a member that suspends the window cleaning robot 20. The hanging part 50 is composed of two pulleys 51 to which the wire 40 extending from the hanging part 30 is connected, and a joint 52 that is joined to the window cleaning robot 20 by a ball joint or the like, and the joint 52 makes it possible to keep the window cleaning robot 20 horizontal.

[0053] The hanging part 50 is suspended from the wire 40, and the two pulleys 51 are rotatable. Therefore, the hanging part 50 is located at the lowest point of the wire 40 between the two hanging parts 30 due to its own weight. The window cleaning robot 20 may be configured to be directly connected to the wire 40.

[0054] The power unit 60 (winding power unit) is disposed behind the hanging unit 30. The power unit 60 can wind and unwind the wire 40 by rotating a motor (not shown) or the like, and can change the position of the hanging unit 50 (window cleaning robot 20) by each performing at least one of winding and unwinding. The left and right power units 60 are connected to a control panel 66, and the control panel 66 controls the winding and unwinding of the wire 40 while synchronizing the motors of the left and right power units 60.

[0055] In this embodiment, the power units 60 are installed on both ends of the roof of the building 10, and the left and right power units 60 respectively wind or unwind the wire 40 to lift the window cleaning robot 20.

[0056] When moving the window cleaning robot 20 suspended from the suspension part 50, the left and right winding lengths are adjusted. This allows the window cleaning robot 20 to move up, down, left and right along the wall surface 11 of the building 10.

[0057] For example, when only the left wire 40 is wound by the left power unit 60, the window cleaning robot 20 moves diagonally upward to the left. On the other hand, when only the right wire 40 is wound by the right power unit 60, the window cleaning robot 20 moves diagonally upward to the right. Furthermore, when the left and right wires 40 are wound simultaneously by the two power units 60, the window cleaning robot 20 moves upward. On the other hand, when the left and right wires 40 are unwound simultaneously by the two power units 60, the window cleaning robot 20 moves downward. Furthermore, when the left wire 40 is wound by the left power unit 60 and the right wire 40 is unwound by the right power unit 60, the window cleaning robot 20 moves to the left. On the other hand, when the left wire 40 is unwound by the left power unit 60 and the right wire 40 is wound by the right power unit 60, the window cleaning robot 20 moves to the right.

[0058] Next, details of each component such as the hanging part 30 will be described. The hanging part 30 is composed of multiple components, and is small and lightweight, so it can be disassembled and manually transported to the rooftop and assembled. Therefore, the lifting device 100 of this embodiment can be installed even in buildings where there is no elevator leading to the rooftop or in places where a large installation space cannot be secured.

[0059] 2 is a diagram showing the hanging unit 30 and the power unit 60. The hanging unit 30 and the power unit 60 are installed on the roof of a building. The hanging unit 30 and the power unit 60 can be placed on a wall W1 on the work target surface of the building where work is to be performed, or on a wall W2 perpendicular to the work target surface.

[0060] The hanging part 30 includes a base member 70, a rotating support member 80 (rotating mechanism, moving mechanism), and a rotating member 90 (moving member). The base member 70 is fixed to the installation part 12 of the building 10. The rotating support member 80 enables the rotating member 90 to rotate relative to the base member 70 (the moving mechanism enables the moving member to move relative to the base member). The rotating member 90 is rotatable so that a tip (specific part) of the rotating member 90 is located on the indoor side (arrow A, inside the building 10) and the outdoor side (arrow B, outside the building 10) of the building 10 (the moving member is movable so that a specific part of the moving member is located inside and outside the building).

[0061] The hanging point 30 is installed on the roof of the building 10 in a manner that protrudes into the air toward the outdoors, and vertical loads are supported by attaching a wire or other support from the indoor side behind the hanging point, and horizontal loads are supported by fixing it to a strong building structure such as the installation point 12 with a parapet holding member 71 (vice mechanism).

[0062] The base member 70 comprises a parapet holding member 71 and a base 73 installed on the parapet holding member 71. The parapet holding member 71 is fixed to the installation portion 12 of the building 10 by a fastening member 72. An insertion hole 74 is formed in the base 73, and the lower protruding portion of the rotation support member 80 (second member 82, third member 83, fourth member 84) is inserted into the insertion hole 74. Details of the rotation support member 80 will be described later.

[0063] The rotating member 90 includes a bracket support member 91 that can be rotated by the rotating support member 80, a length adjustment member 92 installed at the tip of the bracket support member 91, and a tip pulley portion 93 arranged at the tip of the length adjustment member 92. The bracket support member 91 is also formed with a hole 94 through which a wire passes. The size and position of the hole 94 can be any size and shape. The bracket support member 91 is rotatable, but once the adjustment of the rotational position is completed, it is finally fixed by a diagonal brace plate 95 so as not to rotate.

[0064] Thus, a tip pulley unit 93 that adjusts the direction of the wire 40 is disposed at the tip of the rotating member 90 (length adjustment member 92). In addition, a power unit 60 is disposed at the rear end of the base member 70 (base 73).

[0065] The power unit 60 is fixed to the indoor side of the hanging part 30, with the wire 40 extending towards the tip. Since it can be installed simply by placing the heavy power unit 60 on the indoor side, it can be easily installed by hand from the rooftop. In addition, since the power unit 60 is installed behind the tip pulley part 93, the weight of the power unit 60 is prevented from being added to the hanging load, which is expected to have the effect of improving the allowable hanging load.

[0066] 3 is a diagram showing the power unit 60. The power unit 60 releases the wound wire 40 without winding it around a reel or the like. The released wire 40 may be left as is, or may be wound up by a separate winding device (not shown). The power unit 60 includes a winder device 61 and a winder frame 63. The winder device 61 and the winder frame 63 can be separated and transported separately.

[0067] As shown in FIG. 3(A), the winder device 61 has a motor (not shown) disposed therein, and the motor can be driven to wind up the wire. The winder device 61 shown in FIG. 3(A) can employ, for example, a winder device as shown in Japanese Patent Application Laid-Open No. 9-142799. In a commonly used winch (winding machine), the wire is wound around a winding drum, and the length of the wire wound in one revolution varies depending on whether it is randomly wound or multiple wound. However, the winder device (winder type) has a mechanism for releasing the wound wire to the opposite side, so that the sheave rotation amount and the winding length are highly consistent. This allows precise adjustment of the winding and unwinding length of the wire, and therefore ensures high accuracy of the movement coordinates of the lifting object.

[0068] As shown in Fig. 3(A), a hook member 62 is attached to the upper part of the winder device 61. Then, as shown in Fig. 3(B), the winder device 61 can be attached to the winder frame 63 by hooking this hook member 62 to a mounting rod 64 extending in the horizontal direction and disposed on the upper part of the winder frame 63. Note that when the hook member 62 is simply hooked to the mounting rod 64, the winder device 61 is in a hanging state, but ultimately, the winder device 61 is fixed and does not swing. Therefore, the hook member 62 and the mounting rod 64 are intended to improve the ease of work when attaching the winder device 61 to the winder frame 63.

[0069] Further, an auxiliary pulley unit 65 is disposed in the center of the lower part of the winder frame 63. A pulley (not shown) is disposed inside the auxiliary pulley unit 65, and converts the guiding direction of the wire 40 from the front-rear direction to the up-down direction.

[0070] FIG. 4 is a diagram showing the tip pulley unit 93. The tip pulley unit 93 is attached to the tip of the rotating member 90 (length adjustment member 92). The tip pulley unit 93 adjusts the direction of the wire 40 according to the coordinates of the window cleaning robot 20. Specifically, as shown in FIG. 4(A), the tip pulley unit 93 can rotate around the shaft unit X into which the wire 40 is inserted (with the wire 40 as the shaft center) so as to rise up toward the window cleaning robot 20. Also, as shown in FIG. 4(B), the tip pulley unit 93 converts the direction of the wire 40 extending from the power unit 60 to the direction (downward) of the window cleaning robot 20 (see FIG. 1).

[0071] The tip pulley section 93 not only reduces friction of the wire 40 due to the rotation of the pulley, but also allows the pulley itself to rotate freely around the axis of the wire 40 extending from the power section 60 in accordance with the coordinates of the window cleaning robot 20, thereby reducing the load due to twisting generated at the hanging section 30 and reducing wear due to friction and bending load of the wire 40.

[0072] Fig. 5 is a diagram showing the hanging part 30 by its individual components. As shown in Fig. 5, the hanging part 30 can be separated into each component. When assembling the separated components, the parapet holding member 71 is fixed to the installation part 12, and then the base 73 is fixed on top of that, and the rotating support member 80 and bracket support member 91 are installed on top of that, and the length adjustment member 92 and the tip pulley part 93 (see Fig. 2) are attached to the tip of the bracket support member 91 on the indoor side, and then it is rotated to the outdoor side to extend it out and fixed with the diagonal brace plate 95. This allows workers on the roof to safely install the hanging part 30 without having to reach into the air.

[0073] 6 is a diagram showing the details of the rotation support member 80. The rotation support member 80 includes a first member 81 having a flat rectangular parallelepiped shape, a cylindrical second member 82 arranged below the first member 81, a cylindrical third member 83 arranged below the second member 82 and having a smaller diameter than the second member 82, and a cylindrical fourth member 84 arranged below the third member 83 and having the same diameter as the first member 81. The rotation support member 80 employs a turntable mechanism, and when the third member 83 and the fourth member 84 are fixed, the first member 81 and the second member 82 rotate relative to the third member 83 and the fourth member 84. Since a bracket support member 91 is fixed to the first member 81, the bracket support member 91 also rotates with the rotation of the first member 81 and the second member 82.

[0074] When assembling the base 73, the rotation support member 80, and the bracket support member 91, first, as shown in FIG. 6(A), the lower protruding portion (second member 82, third member 83, fourth member 84) of the rotation support member 80 is inserted into the insertion hole 74 of the base 73, and the bracket support member 91 is placed on the rotation support member 80 (first member 81). The fourth member 84 is fixed to the insertion hole 74. This causes the upper bracket support member 91 to rotate around the rotation support member 80 as an axis. Instead of inserting the rotation support member 80 into the base 73, it is also possible to turn the rotation support member 80 upside down, form an insertion hole in the bracket support member 91, and insert it into the bracket support member 91.

[0075] As shown in FIG. 6(B), the anti-tip pin 75 can be inserted from the side of the base 73. The anti-tip pin 75 fixes the rotation support member 80. The portion into which the anti-tip pin 75 is inserted can be a flattened rectangular parallelepiped shape. As shown in FIG. 6(C), the anti-tip pin 75 may have a crescent-shaped notch 75a formed at the tip. As shown in FIG. 6(D), the anti-tip pin 75 may have a protrusion 75b formed with a length that penetrates the rotation support member 80, and a hole may be opened in the rotation support member 80 (third member 83) through which the protrusion 75b penetrates.

[0076] FIG. 7 is a diagram showing how the bracket support member 91 is rotated. The tip pulley part 93 (see FIG. 2) is fixed to the tip (tip of the length adjustment member 92) of the hanging part 30 that protrudes to the outdoor side. Since the bracket support member 91 of the hanging part 30 rotates around the rotating support member 80 attached to the base 73, when installing the tip pulley part 93 (see FIG. 2), the bracket support member 91 is rotated to the indoor side before installation (see arrow C in the figure). After that, the protruding length is adjusted with the length adjustment member 92, and then it is rotated again to the outdoor side (see arrow D in the figure) and fixed with the diagonal brace plate 95. This allows the worker to install the tip pulley part 93 (see FIG. 2) without leaning out.

[0077] 8 to 13 are diagrams showing the procedure for installing the lifting device 100. The lifting device 100 can be installed on the roof of the building 10 by the installation procedure described below.

[0078] As shown in Figure 8(A), the workers carry each part up to the rooftop in its disassembled state. Each part weighs 25 kg or less so that it can be transported manually even in places where a cart cannot pass. In addition to these parts, the workers also carry the control panel 66, wires 40, tools, etc.

[0079] As shown in Figure 8 (B), the parapet holding member 71 is attached to the vertical surface of wall W2 in a direction perpendicular to wall W1 of the work surface (the vertical surface of the surface to be lifted). The reason for attaching it to wall W2 in a direction perpendicular to wall W1 of the work surface is to install the hanging part 30 as close to the edge as possible. When attaching, the parapet holding member 71 is tightened and fixed in place from the indoor side in a vice-like manner.

[0080] As shown in Fig. 9(C), the base 73 is placed on the parapet holding member 71 and fixed with bolts and nuts, etc. As shown in Fig. 9(D), the winder frame 63 is placed on the base 73 and fixed with bolts and nuts, etc.

[0081] As shown in Fig. 10(E), the winder device 61 is attached to the mounting rod 64 of the winder frame 63 using the hook member 62, and fixed with bolts and nuts, etc. As shown in Fig. 10(F), the rotation support member 80 is attached to the base 73, and the tip-over prevention pin 75 is inserted.

[0082] As shown in Fig. 11(G), bracket support member 91 is installed on rotation support member 80 and fixed with bolts and nuts, etc. As shown in Fig. 11(H), length adjustment member 92 having a tip pulley part 93 attached thereto is attached by being inserted into bracket support member 91, and the length is adjusted with positioning pin 96, etc.

[0083] As shown in Fig. 12(I), the wire 40 is passed through the tip pulley portion 93 and penetrated through the hole 94 of the bracket support member 91, and set in the winder device 61. As shown in Fig. 12(J), the bracket support member 91 is rotated around the rotation support member 80 as an axis so as to protrude outdoors.

[0084] As shown in Fig. 13(K), a brace plate 95 is bolted to connect the bracket support member 91 and the base 73. As shown in Fig. 13(L), ​​a stay wire 41 is extended from the base 73 and tied to a sturdy building skeleton 13. Then, by this installation procedure, the lifting device 100 can be installed on the roof of the building 10.

[0085] 14 is a perspective view showing the window cleaning robot 20. The window cleaning robot 20 is a robot that cleans windows of a building 10. The window cleaning robot 20 includes a cleaning unit 21, an operating unit 22, and an adsorption mechanism 23 (fixing mechanism).

[0086] The cleaning unit 21 is a member that cleans the windows of the building, and is provided with a window wiping roll, etc. The operating unit 22 is a member that moves the cleaning unit 21, and moves the cleaning unit 21 up, down, left, and right by a motor and a drive mechanism (not shown).

[0087] The suction mechanism 23 is a device for fixing the window cleaning robot 20 to a window or wall of a building. Two suction mechanisms 23 are arranged on the lower part of the cleaning surface side (the side where the cleaning unit 21 is arranged) of the window cleaning robot 20.

[0088] When the window cleaning robot 20 is lifted along the wall surface 11 of the building 10, the window cleaning robot 20 is suspended from the suspension part 50. For this reason, the position and posture of the window cleaning robot 20 may become unstable due to movement or the influence of wind, and in such a case, it is difficult to clean the window.

[0089] Therefore, the lifting device 100 of this embodiment is equipped with an adsorption mechanism 23 that, when the window cleaning robot 20 is lifted and moved to the target window surface, adsorbs and fixes the window cleaning robot 20 to the wall surface 11, stabilizing its posture and enabling cleaning work to be performed. The adsorption mechanism 23 may be switched between operation and non-operation by remote control, or may be automatically activated when the drive of the power unit 60 ends and automatically terminated before the drive of the power unit 60 starts.

[0090] The fixing method of the suction mechanism 23 includes vacuum suction by a suction pad, magnetic suction by an electromagnet, and lift by a drone, and can be selected according to the material and shape of the target wall. For example, if the wall of the building is a tiled surface with few irregularities, vacuum suction can be used. Also, if the wall of the building is made of metal, magnetic suction can be used. Furthermore, if the wall of the building has a complex shape, a method can be used in which wind is blown from a drone in a direction to press the window cleaning robot 20 against the wall, providing lift to the window cleaning robot 20.

[0091] Due to the nature of cleaning, the window cleaning robot 20 may proceed with cleaning work from the top to the bottom of the building 10. For this reason, it is desirable that two or more suction mechanisms 23 are installed on the bottom (left and right) of the window cleaning robot 20. The reason for this is that when vacuum suction is used for the suction mechanisms 23, suction marks due to the strong suction force are left on the wall surface, so if the suction mechanism 23 is placed on the top of the window cleaning robot 20, there is a possibility that suction marks will remain on areas that have already been cleaned. For this reason, when wiping from the top to the bottom of the building 10, by placing the suction mechanism 23 on the bottom of the window cleaning robot 20, it becomes possible to descend while wiping off the suction marks.

[0092] When using this window cleaning robot 20, the window cleaning robot 20 is attached to the hanging part 50 with the cleaning part 21 and the suction mechanism 23 facing the wall surface of the building 10, and window cleaning is performed (see FIG. 1).

[0093] As described above, according to this embodiment, the following effects are obtained. (1) By installing the hanging points 30 at two points on the roof, the entire wall surface can be lifted and moved. (2) All installation work can be done on the indoor side of the roof, eliminating the need for dangerous work that requires leaning into the air or the use of construction machinery such as aerial work vehicles or cranes, making installation safe and simple. (3) By using a wire as the sling and a winder-type winding device, it is possible to lift and move heavy objects to precise coordinates.

[0094] (4) According to this embodiment, the rotating member 90 is rotatable so that the tip of the rotating member 90 is located on both the indoor and outdoor sides of a building, so that workers can safely perform work related to the rotating member 90 on the indoor side. As a result, a lifting device 100 having a novel configuration can be provided.

[0095] (5) According to this embodiment, the power unit 60 releases the wound wire 40 without winding it. This eliminates the need to wind the wire 40 around a reel or the like, and allows for an accurate winding amount.

[0096] (6) According to this embodiment, the tip pulley unit 93 is disposed in the front and the power unit 60 is disposed in the rear, so that the hanging unit 30 can be well-balanced. (7) According to this embodiment, the end pulley portion 93 can rotate so as to rise up toward the window cleaning robot 20. Therefore, the movement of the end pulley portion 93 can prevent twisting.

[0097] (8) According to this embodiment, the hanging unit 30 and the power unit 60 are installed on the roof of a building, which is effective when installation space cannot be secured around the building.

[0098] (9) According to this embodiment, the hanging unit 30 and the power unit 60 can be placed on the wall of the work surface or on a wall perpendicular to the work surface, so that the hanging unit 30 and the power unit 60 can be placed in various locations.

[0099] (10) According to this embodiment, since the wire 40 is used as the stretching member, an accurate winding amount can be achieved. (11) According to this embodiment, the window cleaning robot 20 performing work on the wall surface of a building can be freely lifted.

[0100] (12) As a new technology, a lifting device that moves a work robot on a wall surface so that the work robot can clean windows on the exterior wall of a building instead of a human is desired. One exemplary problem with this demand is that when a chain is used as a hoist to ensure the coordinate accuracy of the lifting movement, the allowable strength of the chain is not enough to suspend a heavy work robot, and when the power unit is installed on the ground, it is difficult to install if there are plants and sculptures scattered around the building, and the hanging part and pulley part on the roof must be installed on the outdoor side, so that the installation work by leaning over is dangerous. In response to this exemplary problem, the present embodiment can provide a lifting device 100 that can be installed safely and easily and can lift heavy objects using a wire 40 as a hoist.

[0101] Second Embodiment Next, a second embodiment will be described with reference to the drawings. In the following description, parts that perform the same functions as in the first embodiment are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0102] 15 is a diagram showing a lifting device 100-2 of the second embodiment. The lifting device 100-2 of the second embodiment differs from the lifting device 100 of the first embodiment in that the hanging part 30 is changed to a hanging part 30-2. Other points are the same as those of the first embodiment.

[0103] 16 is a diagram showing the hanging part 30-2 and the power unit 60. The hanging part 30-2 and the power unit 60 are installed on the roof of the building 10. The hanging part 30-2 and the power unit 60 can be disposed on a wall W1 on the work target surface of the building where work is to be performed, or on a wall W2 perpendicular to the work target surface.

[0104] The hanging part 30-2 includes two base members 70-2, two slide support members 80-2 (slide mechanism, moving mechanism), a slide member 90-2 (moving member), and a tension support member 97 (resistance part). The base member 70-2 is fixed to the installation part 12 of the building 10. The slide support member 80-2 is disposed on the upper part of the base member 70-2, and allows the slide member 90-2 to slide relative to the base member 70-2 (the moving mechanism allows the moving member to move relative to the base member).

[0105] The slide support member 80-2 slides the slide member 90-2 in a direction parallel to the wall W2 perpendicular to the work surface. However, the orientation, position, shape, etc. of the slide support member 80-2 may be changed between the front and rear slide support members 80-2 so that the slide member 90-2 slides in a direction not parallel to the wall W2 perpendicular to the work surface.

[0106] The slide member 90-2 is arranged so as to penetrate through the interior of the two slide support members 80-2, and is slidable so that the tip (specific part) of the slide member 90-2 is positioned inside the building 10 (arrow A2) and outside the building 10 (arrow B2) (the movable member is movable so that specific parts of the movable member are positioned inside and outside the building).

[0107] The inside of the building 10 is an area where the building and its accessories are present. The outside of the building 10 is an area where the building and its accessories are not present (area other than the inside of the building). The specific part is an arbitrary part of the sliding member 90-2 (a part that is inside the building before the moving member moves).

[0108] The hanging part 30-2 is installed on the roof of the building 10 in a manner that projects into the air toward the outside of the building 10, and vertical loads are supported by a wire or other support attached from the inside of the building 10 behind the hanging part 30-2, and horizontal loads are supported by fixing a base member 70-2 (a vice mechanism) to a strong building frame such as the installation part 12. Details of the base member 70-2 and the slide support member 80-2 will be described later.

[0109] The slide member 90-2 comprises an extension member 91-2 that is slidable by the slide support member 80-2, a length adjustment member 92 installed at the tip of the extension member 91-2, and a tip pulley portion 93 arranged at the tip of the length adjustment member 92. The extension member 91-2 is slidable, but once adjustment of the slide position is complete, it is ultimately fixed by a fixing bolt 31 so that it does not slide.

[0110] Thus, at the tip of the slide member 90-2 (length adjustment member 92), there is disposed a tip pulley unit 93 that adjusts the direction of the wire 40. In addition, behind the base member 70-2, the power unit 60 is disposed.

[0111] The tension support 97 is a member that can be attached to the slide member 90-2. The tension support 97 resists vertical and horizontal forces generated in the hanging part 30-2 by the wire 40 pulling the hanging part 30-2. The tension support 97 has two rectangular column members that extend upward and outward from the building 10 (to the left in the figure). A tension member 42 such as a wire can be connected to the two rectangular column members. During lifting, the vertical and horizontal loads generated in the hanging part 30-2 are supported by tensioning the tension member 42 from the tip of the hanging part 30-2 to a rooftop fixture behind the hanging part 30-2, and the tension support 97 converts each load into a load in the axial direction of the wire 40.

[0112] The power unit 60 is fixed to the installation section 12 behind the hanging part 30-2, and the wire 40 extends toward the tip (toward the tip pulley section 93). Since the heavy power unit 60 can be installed simply by placing it on the installation section 12, it can be easily installed by hand from the rooftop. In addition, since the power unit 60 is installed behind the tip pulley section 93, the weight of the power unit 60 is prevented from being added to the hanging load, which is expected to have the effect of improving the allowable hanging load. The configurations of the power unit 60 and the tip pulley section 93 are as described in Figures 3 and 4.

[0113] FIG. 17 is a diagram showing the details of the base member 70-2 and the slide support member 80-2. As shown in FIG. 17(A), the base member 70-2 includes a parapet holding member 71-2 and a column member 73-2. The parapet holding member 71-2 is a U-shaped member attached to the installation part 12, and is fixed to the installation part 12 of the building 10 by a fastening member 72 (see FIG. 16). The column member 73-2 is a member extending upward from the upper center of the parapet holding member 71-2, and a slide rail 81-2 is attached to the upper part. A hole 94 for passing a wire through is formed in the column member 73-2. The hole 94 can be formed in any size, any shape, and at any position.

[0114] As shown in Fig. 17(B), the protruding member 91-2 has a plurality of holes 32 for inserting the fixing bolts 31. Similarly, holes 33 for inserting the fixing bolts 31 are formed on the side of the slide rail 81-2. Similarly, holes 34 for inserting the fixing bolts 31 are formed on the side of the movable fixed member 82-2 (see Fig. 17(C)). Note that the shape, position and number of each hole are arbitrary. Also, in other drawings, illustration of each hole is omitted in some places.

[0115] As shown in FIG. 17(C), the slide support member 80-2 includes a slide rail 81-2 and a movable fixed member 82-2. The slide rail 81-2 has a concave shape, and a movable fixed member 82-2, which is one size larger than the slide rail 81-2, can be placed on top of the slide rail 81-2. The movable fixed member 82-2 is a member for preventing the protruding member 91-2 from coming off. The slide rail 81-2 and the movable fixed member 82-2 are made of a material with a low friction coefficient such as Teflon (registered trademark) on the inner surface. The fixing bolts 31 can be inserted from the side of the slide support member 80-2 using each hole, and the protruding member 91-2 can be fixed by the fixing bolts 31.

[0116] Fig. 18 is a diagram showing the suspension part 30-2 by its individual components. As shown in Fig. 18, the suspension part 30-2 can be divided into individual components (wire 40, tension member 42, length adjustment member 92, extension member 91-2, tension support member 97, movable fixed member 82-2, slide rail 81-2, base member 70-2, etc.). Note that some components (e.g., tip pulley part 93, etc.) are not shown in the figure.

[0117] When assembling the divided members, the base member 70-2 to which the slide rail 81-2 is attached is fixed to the installation section 12, the overhanging member 91-2 is installed on top of it, the movable fixing member 82-2 is attached to the slide rail 81-2, the length adjustment member 92 and the tip pulley section 93 (see FIG. 2) are attached to the tip of the overhanging member 91-2 inside the building, and then the overhanging member 91-2 (sliding member 90-2) is slid to the outside of the building to extend it, and the tension support member 97 is attached. This allows workers on the roof to safely install the hanging part 30-2 without having to reach into the air.

[0118] FIG. 19 is a diagram showing how the slide member 90-2 is slid. The tip pulley part 93 is fixed to the tip of the slide member 90-2 (length adjustment member 92). Since the slide member 90-2 can slide by the slide rail 81-2 (slide support member 80-2), when installing the tip pulley part 93 (see FIG. 2), the tip of the slide member 90-2 is installed in a state where it is positioned inside the building 10 (see arrow C2 in the figure). After that, the overhanging length is adjusted by the length adjustment member 92, and the slide member 90-2 is slid to the outside of the building 10 (see arrow D2 in the figure) and fixed with a fixing bolt. This allows the installation of the tip pulley part 93 and the like without the worker leaning out.

[0119] 20 to 23 are diagrams showing the procedure for installing the lifting device 100-2. The lifting device 100-2 (hanging part 30-2) can be installed on the roof of the building 10 by the installation procedure described below.

[0120] As shown in Figure 20(A), workers carry each part (winder device 61, winder frame 63, length adjustment member 92, extension member 91-2, tension support member 97, movable fixed member 82-2, slide rail 81-2, base member 70-2, tip pulley section 93, fixing bolt 31, tightening member 72, etc.) in its disassembled state to the roof. Each part weighs 25 kg or less so that it can be transported manually even in places where carts cannot pass. In addition to these parts, workers also carry a control panel 66, wires 40, tension members 42, tools, etc.

[0121] As shown in Figure 20(B), the parapet holding member 71-2 of the base member 70-2 is attached to the vertical surface of the wall W2 in the direction perpendicular to the wall W1 of the work surface (the vertical surface of the surface to be lifted). The reason for attaching it to the wall W2 in the direction perpendicular to the wall W1 of the work surface is because it is desired to install the hanging part 30 as close to the edge as possible. When attaching, the parapet holding member 71-2 is tightened and fixed in place from inside the building 10 in a vice-like manner.

[0122] As shown in Fig. 21(C), the overhanging material 91-2 is placed on the slide rail 81-2. As shown in Fig. 21(D), the movable fixed material 82-2 is attached to the slide rail 81-2, and the overhanging material 91-2 is temporarily fixed.

[0123] As shown in Fig. 22(E), the length adjustment member 92 with the tip pulley part 93 attached is attached by inserting it into the extension member 91-2, and the length is adjusted using a positioning pin 96 or the like. At this time, the wire 40 is passed from the tip pulley part 93 and inserted through a hole 94 in the base member 70-2. In addition, a tension member 42 is attached to the tip of the length adjustment member 92. Then, as shown in Fig. 22(F), the slide member 90-2 is slid forward to extend it (see arrow D2 in the figure), and fixed with a fixing bolt 31.

[0124] As shown in FIG. 23(G), the power unit 60 is disposed behind the base member 70-2, and the power unit 60 is fixed to the base member 70-2 or the installation part 12. At this time, the wire 40 that was passed through earlier is passed through to the power unit 60. As shown in FIG. 23(H), the tension support 97 is attached to the slide member 90-2 (for example, the tension support 97 is attached by disassembling it into a plurality of parts and reassembling it), and the tension member 42 is attached to a fixed object on the roof and tensioned with a lever block (registered trademark) or the like so as not to sag. The tension member 42 can be attached to the tension support 97 inside the building 10 in advance. The tension support 97 may also be attached at any stage prior to this stage. Then, the lifting device 100-2 (hanging part 30-2) can be installed on the roof of the building 10 by such an installation procedure.

[0125] As described above, according to the second embodiment, in addition to the effects of the first embodiment, the following effects are obtained. (1) By installing the hanging parts 30-2 at two locations on the roof, the entire wall surface can be lifted and moved. (2) During installation, all work related to the hanging part 30-2 can be performed inside the building 10, eliminating the need for dangerous work that requires leaning into the air or construction machinery such as aerial work vehicles or cranes, making installation safe and simple. (3) By using the wire 40 as the hoisting device and a winder-type winding device (power unit 60), it is possible to lift and move a heavy object to an accurate coordinate.

[0126] (4) According to this embodiment, the slide member 90-2 is slidable so that the tip of the slide member 90-2 is positioned inside and outside the building 10, so that workers can safely perform work related to the slide member 90-2 inside the building 10. As a result, a lifting device 100-2 having a novel configuration can be provided.

[0127] (5) According to this embodiment, the tip pulley unit 93 is disposed at the tip of the slide member 90-2, and the power unit 60 is disposed behind the base member 70-2, so that a well-balanced hanging portion 30-2 can be achieved.

[0128] (6) According to this embodiment, the hanging unit 30-2 and the power unit 60 are installed on the roof of the building 10, which is effective when installation space cannot be secured around the building 10.

[0129] (7) According to this embodiment, the hanging part 30-2 and the power unit 60 can be placed on the wall W1 of the work surface or on the wall W2 perpendicular to the work surface, so that the hanging part 30-2 and the power unit 60 can be placed in various locations.

[0130] [Modifications] 24 is a diagram showing a hanging part 30-3 of a modified example. Note that parts that perform the same functions as those in the above-mentioned embodiments are given the same reference numerals, and duplicated explanations will be omitted as appropriate.

[0131] 24(A), in the hanging part 30-3 of the modified example, a pin 85 (rotation mechanism) is disposed on the upper part of the base member 70-2, and a rotation member 90-3 (moving member) rotates around the pin 85 as a rotation axis. The rotation member 90-3 is rotatable so that the tip (specific part) of the rotation member 90-3 is located inside the building 10 (see arrow A3) and outside the building 10 (see arrow B3).

[0132] As shown in Fig. 24(B), a pin 85 is disposed on the upper part of the left base member 70-2, and a pin 85 is not disposed on the upper part of the right base member 70-2. The left base member 70-2 corresponds to the base member 70-2 on the front side in Fig. 24(A), and the right base member 70-2 corresponds to the base member 70-2 on the back side in Fig. 24(B).

[0133] In the hanging part 30-3 of the modified example, as in the first embodiment, the tip of the rotating member 90-3 can be extended from the inside of the building 10 (see arrow A3) to the outside of the building 10 (see arrow B3) by rotation. Therefore, in the hanging part 30-3 of the modified example, workers can safely perform work related to the hanging part 30-3 inside the building.

[0134] The respective advantages of the first embodiment, the second embodiment, and the modified example are as follows: The hanging part 30 of the first embodiment is rotatable, and since the tip of the length adjustment member 92 does not protrude outside the building before the bracket support member 91 is extended (FIG. 7), the hanging part 30 can be installed even if there are other structures around the location where it is installed.

[0135] The hanging part 30-2 in the second embodiment is of a sliding type, and the tip of the length adjustment member 92 does not protrude outside the building before the protruding material 91-2 is extended (Figure 19), so that the hanging part 30-2 can be installed even if there are other structures around the location where it is to be installed.

[0136] The hanging part 30-3 of the modified example is rotatable, and the rear end of the overhanging material 91-2 protrudes outside the building 10 before the overhanging material 91-2 is extended (FIG. 24), so it can be installed when a large space can be secured around the location where the hanging part 30-3 is to be installed. Also, in the hanging part 30-3 of the modified example, the rotating member and the rotating mechanism can be simply configured.

[0137] [Modifications] The present invention is not limited to the above-described embodiment, and can be practiced in various modified forms. (1) The lifted object has been described with reference to the example of the window cleaning robot 20, but it may be another type of lifted object. The lifted object may be a robot for inspecting the wall of a building, a robot for painting the wall of a building, a robot for replacing stickers, a robot for removing tiles, a robot for general wall work, or an object or device other than a robot.

[0138] (2) The cleaning range of the window cleaning robot 20 can be changed by changing the installation positions of the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60. In other words, the arrangement positions of the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 are not limited to the examples in FIG. 1 and FIG. 16.

[0139] (3) An auxiliary wire may be provided to connect the two hanging parts 30 (hanging part 30-2, hanging part 30-3) together. (4) Although the suction mechanism 23 has been described as being installed only on the lower part of the window cleaning robot 20, it may be installed only on the upper part of the window cleaning robot 20, or may be installed on the upper and lower parts. In addition, the number of suction mechanisms 23 may be one, or three or more.

[0140] (5) The lifting device 100 may be placed in a location other than the rooftop (such as a balcony or veranda). (6) The rotation mechanism has been described using the example of the rotation support member 80, but it may also be a cylindrical pin. In the case of a pin, the pin can be attached to the base 73, a pin receiving hole can be formed in the bracket support member 91, and the bracket support member 91 can be made rotatable relative to the base 73 by the pin. Conversely, a pin can be attached to the bracket support member 91, a pin receiving hole can be formed in the base 73, and the bracket support member 91 can be made rotatable relative to the base 73 by the pin.

[0141] (7) The hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 can be placed not only on the wall W2 perpendicular to the work surface, but also on the wall W1 of the work surface of the building to be worked on. In the actual operation of the work robot, there is a limit to the length of the wire 40 in a wide building, and the load increases when the work robot reaches the top when the span (spacing) of the two hanging parts 30 (hanging part 30-2, hanging part 30-3) is large. For example, it may be necessary to install the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 at the left end and center to clean half the surface, and then move the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 to the center and right end to clean the remaining half of the surface. In such a case, the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 can be arranged not only on the wall W2 in the direction perpendicular to the work surface, but also on the wall W1 of the work surface of the building to be worked on. In this case, the direction in which the hanging part 30 (hanging part 30-2, hanging part 30-3) is extended can be changed due to the characteristics of the rotatable rotating support member 80 (rotating mechanism) and the pin 85 (rotating mechanism), and also because the orientation, position, and shape of the slide support member 80-2 can be changed. Therefore, the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 can be arranged on the wall W1 of the work surface of the building to be worked on and on the wall W2 in the direction perpendicular to the work surface. Note that the hanging part 30 (hanging part 30-2, hanging part 30-3) and the power unit 60 may be arranged only on the wall W1 of the work surface of the building to be worked on, depending on the situation of the building.

[0142] (8) The moving mechanism has been described using examples of a rotating mechanism and a sliding mechanism, but may be a mechanism that combines these mechanisms or may be other mechanisms. Also, the moving member has been described using examples of a rotating member and a sliding member, but may be a member that combines these mechanisms or may be other members.

[0143] (9) The tension support member 97 of the second embodiment does not have to be attached, for example, when the lifted load is light. Also, the tension support member 97 of the second embodiment can be attached to the hanging part of the first embodiment or the modified example.

[0144] (10) The specific portion has been described using the example of the tip of a moving member (rotating member 90, sliding member 90-2, etc.), but it may be a portion a predetermined distance away from the tip toward the rear end, a central portion of the moving member, a portion for attaching the tip pulley unit, a portion a predetermined distance away from the rear end toward the tip, the rear end, etc. In this way, it is possible to deal with a situation in which the tip of the moving member is installed slightly outside the building 10 at the time of initial installation.
