Move in the direction. Further, when the elevating member 34 moves in the vertical direction with respect to the beam member 33 by the vertical movement mechanism 43 by the pantograph mechanism 36, the first link member 58 and the second link member 59 rotate around the central axis 61. Due to the deformation of the X-shaped link mechanism 60 and the rotation of the rollers 63 to 65, the elevating member 34 moves in the vertical direction with respect to the beam member 33.

In the present embodiment, the vertical movement mechanism 43 by the pantograph mechanism 36 is provided at one end in the length direction of the beam member 33 and the elevating member 34, specifically, the length of the beam member 33 and the elevating member 34. Although arranged at the rear end in the direction, the X-shaped link mechanism 60 is located at the central portion in the length direction of the beam member 33 and the elevating member 34, as shown in FIGS. 8, 9 and 13. Alternatively, since it is arranged in a substantially central portion, the vertical movement of the elevating member 34 with respect to the beam member 33 by the vertical movement mechanism 43 can be performed while maintaining the parallel state or the substantially parallel state of the elevating member 34 with respect to the beam member 33. You can do it.

As shown in FIG. 10, two wall members 66 are fixedly arranged on the upper surface of the elevating member 34 so as to be separated from each other on the left and right sides, and as shown in FIG. 3, these wall members 66 are fixedly arranged.

See also). As shown in FIG. 3, such groove portions 67 are provided on the upper surface of each of the elevating members 34 arranged at both left and right ends of the frame-shaped structure 20. A mounting member 68 for mounting the take-up shaft 4 shown in FIG. 2 on the elevating member 34 is inserted and arranged in each groove portion 67, and has a vertical dimension larger than that of the wall member 66. These mounting members 68 are two support members provided in the frame-shaped structure 20 apart from each other in the length direction of the take-up shaft 4 in order to support the take-up shaft 4.

As shown in FIGS. 3 and 8, the mounting member 68 according to the present embodiment is arranged in the horizontal direction orthogonal to the length direction of the take-up shaft 4 or in the front-rear direction which is substantially horizontal. It is made up of only two mounting semi-members 68A. Further, since each mounting half member 68A is placed in the groove portion 67, the operator can manually change the arrangement position of each mounting half member 68A in the groove portion 67, and therefore, for this reason. The distance between the two mounting half members 68A is adjustable.

In the frame-shaped structure 20 constituting the building material lifting device according to the present embodiment described above, the left-right movement mechanism 25 shown in FIG. 3 described above causes two girder members 26 with respect to the basic member 21. When moving in the left-right direction, the two beam members 33 coupled to these girder members 26 also move in the left-right direction, and each elevating member 34 arranged above the beam members 33 has a pantograph mechanism. Since the beam member 33 is connected in the left-right direction via the 36 and the front-back movement mechanism 35, the elevating member 34 also moves in the left-right direction together with the beam member 33, and is placed on these elevating members 34. The member 68 also moves in the left-right direction. Further, when the elevating member 34 moves in the front-rear direction with respect to the beam member 33 by the above-mentioned front-back movement mechanism 42, the mounting member 68 also moves in the front-rear direction. Further, when the elevating member 34 moves in the vertical direction with respect to the beam member 33 by the vertical movement mechanism 43 by the pantograph mechanism 36, the mounting member 68 also moves in the vertical direction.

Therefore, as support members for supporting the take-up shaft 4, two mounting members 68 arranged on the frame-shaped structure 20 apart from each other in the length direction of the take-up shaft 4 are the left-right movement mechanism 25. The front-back movement mechanism 42 and the up-down movement mechanism 43 enable three-dimensional movement of left-right, front-back, and up-down, and are arranged in the frame-shaped structure 20.

Further, in the present embodiment, the two first intermediate members 22, the second intermediate member 23, and the second intermediate member 23 of each member constituting the frame-shaped structure 20 are coupled to each other. The left and right moving table 44 (see FIG. 3) that moves in the left-right direction by the left-right moving mechanism 25 with respect to the basic member 21 by the girder member 26 and the two beam members 33 coupled to each girder member 26. Will be configured. Further, the elevating member 34 that moves in the front-rear direction with respect to the beam member 33 by the front-back moving mechanism 42 is also a front-back moving table that can move in the front-rear direction with respect to the left-right moving table 44. Since there are two elevating members 34, two front-rear moving tables are also provided in the frame-shaped structure 20.

Further, in the present embodiment, the left-right moving table 44 and the front-back moving table by the elevating member 34 move two-dimensionally in the left-right direction and the front-back direction by the left-right moving mechanism 25 and the front-back moving mechanism 42 with respect to the basic member 21. Since the table is configured and the two mounting members 68 are arranged on the two elevating members 34, the two mounting members 68 are arranged on the two-dimensional moving table. Will be there.

Further, since each elevating member 34 serving as a front-rear moving table moves in the vertical direction with respect to the left-right moving table 44 by the vertical moving mechanism 43, each of the front-rear moving tables moves up and down with respect to the left-right moving table 44. It is movable in the direction, and one mounting member 68 is arranged by two mounting half members 68A for each of these front-rear moving tables.

Further, in the present embodiment, each of the elevating members 34 is a member that moves in the vertical direction with respect to the beam member 33, and also serves as a front-rear moving table that moves in the front-rear direction with respect to the beam member 33. Therefore, the frame-shaped structure 20 has a structure in which the members are also used.

The battery and the control device for controlling these electric motors are mounted on the frame-shaped structure 20 (not shown). Further, each of the electric motors is driven and controlled by the control device to which a signal is sent from the operation device operated by the operator. The transmission of the signal from the operating device to the control device may be wireless or wired by an electric cable. If the wireless system is used, the electric cable is not connected to the frame-shaped structure 20, so that the frame-shaped structure 20 can be easily handled.

Further, in the present embodiment, the control device that receives the signal from the operating device individually has two electric motors 54 of the pantograph mechanism 36 arranged as vertical movement mechanisms 43 at the left and right ends of the frame-shaped structure 20. It is designed to be driven and controlled. Therefore, each pantograph mechanism 36 is individually driven by an operation by the operating device and a control device that operates based on this operation, whereby the pantograph mechanism 36 moves up and down, respectively. The height position of the mounting member 68 arranged on the member 34 can be adjusted individually.

Further, in the present embodiment, the control device includes an electric motor of a front-rear moving mechanism 42 provided for each of two beam members 33 and elevating members 34 arranged at both left and right ends of the frame-shaped structure 20. It is driven and controlled individually. Therefore, each of the front-rear movement mechanisms 42 is also individually driven by the operation by the operating device and the control device that operates based on this operation, and thereby moves in the front-rear direction by these front-back movement mechanisms 42, respectively. The position of the mounting member 68 arranged on the elevating member 34 in the front-rear direction can also be adjusted individually.

FIG. 14 shows a state when the frame-shaped structure 20 is set on the fork 81 of the forklift vehicle 80 which is a lifting means for raising the frame-shaped structure 20. The fork 81 that moves up and down with respect to the main body of the forklift vehicle 80 includes a vertically extending portion 81A extending vertically and a front extending portion 81C extending forward from the lower end of the vertically extending portion 81A via the connecting portion 81B. It has an L-shape or a substantially L-shape. After the frame-shaped structure 20 is placed on the floor 82, the fork 81 is lowered to advance the forklift vehicle 80, so that the forward extending portion 81C of the fork 81 is a square tube member of the frame-shaped structure 20. It is inserted inside the formed basic member 21. As a result, the frame-shaped structure 20 is set on the fork 81 of the forklift vehicle 80.

FIG. 3 shows the relationship between the basic member 21 and the fork 81 at this time, with the fork 81 as a two-dot chain line. An opening 21A for fitting the vertically extending portion 81A and the connecting portion 81B of the fork 81 is formed on the upper surface of the rear end of each basic member 21, and the opening 21A also opens the rear end surface of the basic member 21. It is supposed to be done. At the rear end of each basic member 21, a slip-out preventing means 83 is provided that closes a part of the opening portion 21A of the opening 21A that opens the rear end surface of the basic member 21. The slip-out preventing means 83 includes a bolt 84 in which the shaft portion 84A crosses the opening 21A in the left-right direction, and a nut 85 screwed to the end of the shaft portion 84A outside the basic member 21. The shaft portion 84A forming the main portion of the escape preventing means 83 is located on the rear side of the connecting portion 81B which bends and connects the vertically extending portion 81A and the front extending portion 81C of the fork 81. A part of the opening 21A that opens the rear end surface of the basic member 21 is closed (see also FIG. 14 in which the escape prevention means 83 is shown).

Therefore, after setting the frame-shaped structure 20 on the fork 81 of the forklift vehicle 80 as described above, when the escape prevention means 83 composed of the bolt 84 and the nut 85 is attached to the basic member 21, the basic member 21 becomes the fork 81. The forward exit from the forward extending portion 81C is prevented by the shaft portion 84A of the bolt 84 of the escape preventing means 83 coming into contact with the connecting portion 81B of the fork 81. Therefore, the frame-shaped structure 20 is attached to the fork 81. It can be set in a stable state by preventing it from falling off. Further, since the escape prevention means 83 is composed of a bolt 84 and a nut 85 that can be separated from the basic member 21, the frame-shaped structure 20 can be formed by separating the bolt 84 and the nut 85 from the basic member 21. It can also be removed from the fork 81.

Therefore, the frame-shaped structure 20 according to the present embodiment serves as an attachment base that is detachably set on the fork 81 of the forklift vehicle 80, which is a lifting means for raising the frame-shaped structure 20. There is.

FIG. 14 shows a state when the mounting work for mounting the winding shaft 4 shown in FIG. 2 on the mounting member 68 of the frame-shaped structure 20 is completed. In this mounting operation, for example, the frame-shaped structure 20 set on the fork 81 is inserted into the lower side of the transport carriage on which the take-up shaft is mounted by traveling the forklift vehicle 80, and then the fork 81 is raised. By raising the frame-shaped structure 20 as well, the take-up shaft 4 is delivered from the mounting member provided on the transport carriage to the mounting member 68 of the frame-shaped structure 20. Of course, the take-up shaft 4 may be mounted on the mounting member 68 of the frame-shaped structure 20 by other work, for example, by using a device such as a chain block or by the manual work of the operator. ..

Of the mounting members 68, at least the bottom surface portion in contact with the elevating member 34 has a large coefficient of friction with the metal that is the material of the elevating member 34, for example, because it is formed of natural rubber, synthetic rubber, or the like. Even if the winding shaft 4 is mounted on the mounting member 68, the two mounting half members 68A constituting the mounting member 68 do not move backward from the winding shaft 4.

In FIG. 15, the forklift vehicle 80 was run to the installation site of the shutter device in order to hold the take-up shaft 4 on the two brackets 3 attached to the high places of the skeleton 8 also shown in FIG. Later, the state in which the frame-shaped structure 20 and the take-up shaft 4 are lifted by raising the fork 81 is shown by making the forklift vehicle 80 a two-dot chain line.

In order to hold the take-up shaft 4 on the two brackets 3, as can be seen from FIG. 16, the forklift vehicle 80, which is the above-mentioned lifting means, is driven close to these brackets 3, and the fork 81 is moved. By raising it, the height position of the take-up shaft 4 mounted on the mounting member 68 of the frame-shaped structure 20 is raised to a position close to the height position where the bracket 3 is arranged, and then the work is performed. By operating the above-mentioned operating device by a person, the elevating member 34 is raised by driving the vertical movement mechanism 43 provided in the frame-shaped structure 20, and the height of the take-up shaft 4 mounted on the mounting member 68 is raised. The length of the take-up shaft 4 mounted on the mounting member 68 by matching the vertical position with the height position of the bracket 3 and moving the left-right moving table 44 in the left-right direction by the left-right moving mechanism 25. The left-right positions of both ends in the direction are aligned with the left-right positions of the bracket 3.

After that, the elevating member 34 is advanced by the drive of the front-rear moving mechanism 42 provided in the frame-shaped structure 20 by the operation of the operating device by the operator, and the winding shaft mounted on the mounting member 68 is mounted. 4 is moved to the position where the bracket 3 is arranged, and the above-mentioned neck portion 4A of the take-up shaft 4 is inserted into the recess 3A provided in the bracket 3 with a forward opening. By performing this insertion operation for each of the two brackets 3, both ends of the take-up shaft 4 in the length direction are held by the two brackets 3.

When performing the above work, for example, the floor 86 on which the forklift vehicle 80 shown in FIG. 15 has an inclination angle, or the height position where the two brackets 3 are arranged is slightly up and down. If there is a deviation, the height positions of both ends of the take-up shaft 4 in the length direction do not match the height positions of the recesses 3A of the two brackets 3. Therefore, in such a case, the electric motors 54 of the two pantograph mechanisms 36 arranged at the left and right ends of the frame-shaped structure 20 are individually driven and controlled by the operation of the operating device by the operator. Therefore, the height positions of both ends of the take-up shaft 4 in the length direction are individually adjusted by the mounting members 68 provided on each of the two elevating members 34, and the take-up shaft 4 is adjusted by this individual adjustment. After matching the height positions of both ends in the length direction with the height positions of the recesses 3A of the two brackets 3, the elevating member is driven by the front-back movement mechanism 42 arranged in the frame-shaped structure 20. By advancing 34, both ends of the take-up shaft 4 in the length direction are inserted into the recesses 3A of the two brackets 3.

As can be seen from the above description, in the present embodiment, the vertical movement mechanism 43, which is arranged as two pantograph mechanisms 36 in the frame-shaped structure 20, can be individually driven by the operation device and the control device. Therefore, the vertical support positions of the take-up shaft 4 supported by the two mounting members 68 arranged apart from each other in the length direction of the take-up shaft 4 on the frame-shaped structure 20 are moved up and down. By driving the mechanism 43 individually, it can be adjusted individually. Therefore, the lifting work of the take-up shaft 4 is performed by setting the height position of each end of the take-up shaft 4 in the length direction of two. This can be done while matching the height position of the bracket 3.

Further, as shown in FIG. 15, when the forklift vehicle 80 is driven to the installation site of the shutter device in which the two brackets 3 are arranged and stopped, the forklift vehicle 80 has the two brackets 3. When the forklift vehicle 80 stops without accurately facing each other and the posture of the forklift vehicle 80 with respect to these brackets 3 is diagonally facing each other, the left and right sides of the frame-shaped structure 20 are operated by the operator by operating the operating device. The electric motors of the two front-rear moving mechanisms 42 arranged at both ends are individually driven and controlled, whereby the two elevating members 34 are individually moved in the front-rear direction, whereby these elevating members 34 are used. The positions of both ends of the take-up shaft 4 in the length direction are individually adjusted by the mounting member 68 arranged in the two brackets 3, thereby fitting the take-up shaft 4 into the recesses 3A of the two brackets 3. Insert both ends in the length direction.

As can be seen from the above description, in the present embodiment, the front-rear movement mechanisms 42 arranged at the left and right ends of the frame-shaped structure 20 can also be individually driven by the operation device and the control device. Therefore, for each end portion of the take-up shaft 4 supported by the two mounting members 68 which are arranged apart from each other in the length direction of the take-up shaft 4 in the frame-shaped structure 20 in the length direction. The position in the front-rear direction can be individually adjusted by individually driving each front-back movement mechanism 42, and therefore, both ends of the take-up shaft 4 in the length direction are supported by two brackets 3. The work for making it can be easily performed.

Further, according to the lifting device according to the present embodiment, the mounting members 68 provided in the frame-shaped structure 20 apart from each other in the length direction of the winding shaft 4 in order to support the winding shaft 4 are Since the left-right movement mechanism 25, the front-back movement mechanism 42, and the up-down movement mechanism 43 make it possible to move in three dimensions of left-right, front-back, and up-down and are arranged in the frame-shaped structure 20, the take-up shaft 4 The lifting operation can be performed while the positions of the respective ends of the take-up shaft 4 in the length direction are aligned with the holding positions by the two brackets 3 in three dimensions of left-right, front-back, and up-down.

Further, in the frame-shaped structure 20 according to the present embodiment, as shown in FIG. 9, the first link member 58 and the second link member 59 are the main members between the beam member 33 and the elevating member 34. When the winding shaft 4 which is a heavy object is mounted on the mounting member 68 of the elevating member 34, the X-shaped link mechanism 60 is arranged. In addition, since it is arranged at a position that coincides with or substantially coincides with the position in the front-rear direction on which the downward weight of the take-up shaft 4 acts, the weight of the take-up shaft 4 can be freely deformed up and down to support this weight. It can be effectively supported by the X-shaped link mechanism 60 and transmitted to the beam member 33. In other words, the X-shaped link mechanism 60 moves up and down with the beam member 33 at a position that coincides with or substantially coincides with the position in the front-rear direction on which the weight acts in order to support the downward weight of the take-up shaft 4. It is a support mechanism that is vertically deformable and arranged between the member 34 and the elevating member 34 even if the take-up shaft 4 is mounted on the mounting member 68 by this support mechanism. It is possible to prevent the posture from being tilted.

In the pantograph mechanism, which is the above-mentioned vertical movement mechanism for moving the elevating member in the vertical direction with respect to the beam member, the downward weight of the take-up shaft acts between the beam member and the elevating member. By arranging the elevating member at two locations before and after the location, it may be possible to prevent the elevating member from being in an inclined posture with respect to the beam member. Further, when the pantograph mechanism 36 described above is arranged between the rear end portion of the beam member 33 and the rear end portion of the elevating member 34 as in the present embodiment, it is between the beam member 33 and the elevating member 34. By arranging the pantograph mechanism at a position in the front-rear direction on which the downward weight of the take-up shaft acts or at a position close to this position, it is possible to prevent the elevating member 34 from being in an inclined posture with respect to the beam member 33. You may do so.

As described above, after the work of inserting the neck portions 4A provided at both ends of the take-up shaft 4 in the length direction into the recesses 3A of the two brackets 3, they are rotatably arranged in the neck portion 4A. Work to connect the bearing member 12 to the bracket 3 with a bolt or the like, work to attach the switch 5 and the driving force transmission device 6 shown in FIG. 1 to one of the two brackets 3, and winding. The shutter device is performed by performing the remaining work such as connecting the upper end of the shutter curtain 1 to the shaft 4, attaching the guide rail 2 to the skeleton 7 such as a pillar, and further attaching the shutter case 9 to the skeleton 8. Construction work is completed.

FIG. 17 shows a case where the take-up shaft 4', which has a larger diameter than the take-up shaft 4, is mounted on the mounting member 68. The take-up shaft 4'is a building material having a larger dimension in the front-rear direction, which is a horizontal direction orthogonal to the length direction of the take-up shaft 4 or a substantially horizontal direction, as compared with the take-up shaft 4. The distance between the two mounting half members 68A arranged in the groove 67 provided in the elevating member 34 is set to the placement position of at least one mounting half member 68A among these mounting half members 68A. It changes in the front-back direction by adjusting by the person.

Further, in FIG. 18, the building material to be mounted on the mounting member 68 is coupled to the winding shaft 4 at the upper end in order to open and close the winding shaft 4 and the entrance / exit 10 of the building shown in FIGS. 1 and 2. The case where the combined body 87 with the shutter curtain 1 wound around the winding shaft 4 is used is shown. Since the combined body 87 has a larger diameter than the take-up shaft 4'in FIG. 17, the distance between the two mounting half members 68A is made larger than the distance shown in FIG.

As described above, the mounting member 68 according to the present embodiment is composed of two mounting half members 68A arranged in the front-rear direction, and the distance between these mounting half members 68A is adjustable, so that the front and rear mounting members 68 can be adjusted.
