Note that the subject of the present disclosure is not limited to the following embodiments, and may include modifications of any constituent elements of the embodiments or any constituent elements of the embodiments within the scope of the spirit of the present disclosure. can be omitted.

Embodiment 1.
When an elevator is installed in a building, a plurality of elevator members constituting the elevator are transported into a hoistway of the building. The plurality of elevator members include elongated members such as elevator rails and elevator machine platform beams. A member transporting device of the present disclosure transports a long member.

FIG. 1 is a configuration diagram showing a state in which a long member is being transported using the member transporting device according to the first embodiment. In this embodiment, the elongated member transported by the member transporting device 1 is an elevator rail 2. Furthermore, in this embodiment, the destination space in which the elongated member is transported is the hoistway 3 of the elevator. The elevator rail 2 is transported from a landing 4 of a building through a landing entrance 5 into a hoistway 3.

The member transport device 1 includes a truck 6 and a lifting machine 7. When the elevator rail 2 is transported from the landing 4 into the hoistway 3, the elevator rail 2 is lifted up by the lifting machine 7 while being placed on the truck 6. The elevator rail 2 has a first end 2a and a second end 2b. The lifting machine 7 lifts up the second end 2b of the elevator rail 2.

The lifting machine 7 has a hanging body 71, a lifting machine main body 72, and an operation section 73.

The hanging body 71 is a chain for hanging the elevator rail 2. As the hanging body 71, a wire rope may be used. The hanging body 71 can be connected to the second end 2b of the elevator rail 2. The second end portion 2b of the elevator rail 2 is provided with a connection hole that is a through hole. The hanging body 71 is connected to the second end 2b by passing a hook provided at the end of the hanging body 71 through the connection hole.

The lifting machine main body 72 can be installed within the hoistway 3. When the lifting machine main body 72 is installed in the hoistway 3, the position of the lifting machine main body 72 is higher than the landing 4. The lifting machine main body 72 moves the hanging body 71 upward by winding up the hanging body 71, and moves the hanging body 71 downward by letting out the hanging body 71. That is, the lifting machine main body 72 moves the hanging body 71 in the vertical direction.

The lifting machine main body 72 has a motor. The lifting machine main body 72 is operated by the driving force of the motor. Thereby, the lifting machine main body 72 moves the hanging body 71 in the vertical direction by the driving force of the motor.

The operation unit 73 is a portable device that can be operated at a position remote from the lifting machine main body 72. In this embodiment, the operation unit 73 performs wireless communication with the lifting machine main body 72. Thereby, the worker 8 who transports the elevator rail 2 using the member transport device 1 can operate the operating section 73 at the landing 4 located outside the hoistway 3.

The lifting machine main body 72 operates according to the operation of the operating section 73. The operation unit 73 is operated by selecting either an ascending operation or a descending operation. The lifting machine main body 72 moves the hanging body 71 upward by a lifting operation of the operating part 73, and moves the hanging body 71 downward by a lowering operation of the operating part 73.

The trolley 6 has a base 61, a handle portion 62, a mounting portion 63, a pair of front wheels 64, and a pair of rear wheels 65.

FIG. 2 is a perspective view showing the truck 6 of FIG. 1. A loading surface 611 is formed on the base 61. The pedestal 61 is arranged with the loading surface 611 facing upward. The elevator rail 2 is placed on the loading surface 611. The pedestal 61 can be expanded and contracted in a direction in which the distance between the front end and the rear end of the pedestal 61 changes. Thereby, the pedestal 61 can expand and contract in the direction along the loading surface 611.

FIG. 3 is a perspective view showing the truck 6 when the base 61 of FIG. 2 is retracted. 4 is an enlarged view showing the main parts of the pedestal 61 shown in FIG. 2. As shown in FIG. The pedestal 61 has a plurality of slide members 612. The plurality of slide members 612 are sequentially connected to each other so as to be slidable in the direction in which the base 61 expands and contracts. The pedestal 61 expands and contracts when the plurality of slide members 612 slide with respect to each other.

In this embodiment, the shape of each slide member 612 is cylindrical, and the cross-sectional shape of each slide member 612 is rectangular. Further, in the present embodiment, the cross-sectional area of the plurality of slide members 612 becomes smaller sequentially from the front end and the rear end of the pedestal 61 toward the center of the pedestal 61. As a result, in this embodiment, a plurality of slide members 612 can be sequentially inserted into the inside of the slide members 612 located at each of the front end and rear end of the base 61 while sliding with respect to each other.

The pedestal 61 is contracted by sequentially inserting a plurality of slide members 612 inside the slide members 612 located at the front end and the rear end of the pedestal 61, respectively. When the pedestal 61 is contracted, as shown in FIG. 3, the two slide members 612 located at the front end and the rear end of the pedestal 61 are lined up adjacent to each other.

The pedestal 61 extends by sequentially pulling out a plurality of slide members 612 from the slide members 612 located at the front end and the rear end of the pedestal 61, respectively. When the pedestal 61 is extended, as shown in FIG. 2, a plurality of slide members 612 are continuously arranged between two slide members 612 located at the front end and the rear end of the pedestal 61. The distance from the rear end to the front end of the pedestal 61 increases as the pedestal 61 extends from its contracted state.

A pair of front wheels 64 and a pair of rear wheels 65 are attached to the back surface of the base 61. The back surface of the pedestal 61 is the surface opposite to the loading surface 611 of the pedestal 61. The pedestal 61 is supported by a pair of front wheels 64 and a pair of rear wheels 65. The trolley 6 moves on the floor of the hall 4 while rotating each of a pair of front wheels 64 and a pair of rear wheels 65.

The pair of front wheels 64 are attached to a slide member 612 located at the front end of the pedestal 61. The pair of rear wheels 65 are attached to a slide member 612 located at the rear end of the base 61. Thereby, the distance from the pair of rear wheels 65 to the pair of front wheels 64 changes as the base 61 expands and contracts. Therefore, when the pedestal 61 is extended, the distance from the pair of rear wheels 65 to the pair of front wheels 64 is greater than when the pedestal 61 is contracted.

The handle portion 62 is a frame fixed to the rear end portion of the base 61. The handle portion 62 is fixed to the base 61 in a state that it stands up from the loading surface 611. The worker 8 moves the cart 6 while holding the handle portion 62.

The attachment portion 63 is provided at the rear end of the pedestal 61. In this embodiment, the attachment part 63 is arranged inside the handle part 62. The mounting portion 63 has a pair of support columns 631 and a connecting shaft 632.

A pair of support columns 631 are fixed to the pedestal 61. Each of the pair of support columns 631 is connected to the handle portion 62. The pair of support columns 631 are arranged apart from each other in the width direction of the pedestal 61. The width direction of the pedestal 61 is a direction perpendicular to the direction in which the pedestal 61 expands and contracts, and is a direction along the loading surface 611.

The connecting shaft 632 is a pin that connects the first end 2a of the elevator rail 2 to the pedestal 61. The connecting shaft 632 is detachably attached to each of the pair of support columns 631. Thereby, the connecting shaft 632 can be attached to and detached from the base 61 via the pair of support columns 631.

The connecting shaft 632 is arranged between the pair of support columns 631. Further, the connecting shaft 632 is arranged at a position away from the pedestal 61. When the truck 6 is placed with the loading surface 611 facing upward, the connecting shaft 632 is placed at a higher position than the loading surface 611. Further, the connecting shaft 632 is arranged at a position outside the rear end of the pedestal 61 in the direction in which the pedestal 61 expands and contracts.

The connecting shaft 632 intersects the direction in which the base 61 expands and contracts, and is arranged along the loading surface 611. In other words, the pedestal 61 is expandable and retractable in a direction intersecting the connecting shaft 632 and along the loading surface 611. In this embodiment, the connecting shaft 632 is arranged along the width direction of the base 61.

In this embodiment, each of the pair of support columns 631 is provided with an insertion hole. Further, in this embodiment, the connecting shaft 632 is attached to the pair of support columns 631 with both ends of the connecting shaft 632 inserted into each insertion hole. The connecting shaft 632 is removed from the pair of support columns 631 by coming out of each insertion hole.

FIG. 5 is an enlarged view showing a state in which the elevator rail 2 is connected to the base 61 by the connection shaft 632 of FIG. 4. The first end 2a of the elevator rail 2 is provided with a connecting hole 21, which is a through hole. When the elevator rail 2 is lying on the loading surface 611, the position of the connecting hole 21 is at the same height as the position of the connecting shaft 632.

The inner diameter of the coupling hole 21 is larger than the outer diameter of the coupling shaft 632. Thereby, the connecting shaft 632 can be inserted into the connecting hole 21. When the connecting shaft 632 is passed through the connecting hole 21, a gap is created between the inner peripheral surface of the connecting hole 21 and the outer peripheral surface of the connecting shaft 632.

The connecting shaft 632 is attached to the first end 2a of the elevator rail 2 by being passed through the connecting hole 21, and removed from the first end 2a of the elevator rail 2 by being pulled out of the connecting hole 21. . Therefore, the connecting shaft 632 can be attached to and detached from the first end 2a of the elevator rail 2.

The first end 2 a of the elevator rail 2 is connected to the pedestal 61 by a connecting shaft 632 . The first end 2a of the elevator rail 2 is connected to the base 61 by attaching a connecting shaft 632 passed through the connecting hole 21 to a pair of support columns 631. Therefore, in a state where the elevator rail 2 is connected to the base 61 by the connecting shaft 632, the connecting shaft 632 is passed through the connecting hole 21.

When the elevator rail 2 is connected to the base 61 by the connecting shaft 632, the elevator rail 2 is rotatable about the connecting shaft 632 in a direction in which the angle of the elevator rail 2 with respect to the loading surface 611 changes. . When the elevator rail 2 rotates around the connecting shaft 632 in a direction in which the angle of the elevator rail 2 with respect to the loading surface 611 increases, the elevator rail 2 rises.

When the elevator rail 2 is connected to the pedestal 61 by the connecting shaft 632, the angle of the elevator rail 2 with respect to the loading surface 611 increases as the elevator rail 2 is pulled up by the lifting machine 7. When the elevator rail 2 is pulled up by the lifting machine 7, it rotates around the connecting shaft 632 in a direction in which it rises from a state where it lies down on the loading surface 611.

FIG. 6 is an enlarged view showing the attachment portion 63 when the elevator rail 2 of FIG. 5 is inclined with respect to the loading surface 611. When the elevator rail 2 rotates around the connecting shaft 632 in the direction in which the elevator rail 2 rises, a portion of the first end 2a of the elevator rail 2 moves to a position lower than the loading surface 611. However, the connecting shaft 632 is arranged at a position outside the rear end of the base 61 in the direction in which the base 61 expands and contracts. Thereby, the elevator rail 2 can rise without the first end 2a interfering with the pedestal 61.

Next, a member transport method for transporting the elevator rail 2 from the landing 4 into the hoistway 3 using the member transport device 1 will be described. FIG. 7 is a flowchart showing the member transport method according to the first embodiment. The member transportation method includes a loading step S1, a connecting step S2, a connecting step S3, and a carrying step S4. When transporting the elevator rail 2 from the hall 4 to the hoistway 3, a loading step S1, a connecting step S2, and a connecting step S3 are performed, and then a carrying step S4 is performed. In this embodiment, each process is performed in the order of loading process S1, connection process S2, connection process S3, and carrying-in process S4. The worker 8 performs each of the loading step S1, the connecting step S2, the connecting step S3, and the carrying-in step S4 at the landing 4.

<Loading process S1>
In the loading step S1, the elevator rail 2 is placed on the loading surface 611 of the pedestal 61. At this time, the pedestal 61 is in an extended state. Moreover, at this time, the elevator rail 2 is brought into a state in which it is lying down on the loading surface 611. Furthermore, at this time, the length of the pedestal 61 is adjusted to correspond to the length of the elevator rail 2. Moreover, at this time, the longitudinal direction of the elevator rail 2 placed on the loading surface 611 is made to match the direction in which the pedestal 61 expands and contracts.

<Connection process S2>
In the connection step S2, the first end 2a of the elevator rail 2 is connected to the base 61 by the connection shaft 632. That is, in the connection step S2, the connection shaft 632 removed from the pair of support columns 631 is passed through the connection hole 21 of the first end 2a of the elevator rail 2, and the connection shaft 632 passed through the connection hole 21 is inserted into the pair of support columns 631. It is attached to the support column 631. Thereby, the first end 2a of the elevator rail 2 is connected to the base 61 by the connecting shaft 632.

After the loading step S1 and the connecting step S2 and before the connecting step S3, the trolley 6 carrying the elevator rail 2 is placed in the landing 4. The trolley 6 is arranged with the front end of the pedestal 61 facing the landing entrance 5.

<Connection process S3>
In the connection step S3, the elevator rail 2 is connected to the lifting machine 7. Specifically, in the connection step S3, the hanging body 71 is delivered to the landing 4 from the lifting machine main body 72 installed in the hoistway 3 through the landing entrance 5. At this time, the lifting machine main body 72 is operated by operating the operating section 73 at the landing 4. Thereafter, the second end 2b of the elevator rail 2 is connected to the hanging body 71 at the landing 4.

FIG. 8 is a configuration diagram showing the state of the member transporting device 1 after carrying out each of the loading step S1, the connecting step S2, and the connecting step S3 of FIG. 7. In the hall 4, the elevator rail 2 is placed on a truck 6 with the second end 2b facing the hall entrance 5. The hanging body 71 of the lifting machine 7 is connected to the second end 2b of the elevator rail 2 from the lifting machine main body 72 in the hoistway 3 through the landing entrance 5. In this state, the carrying-in step S4 is carried out.

<Carrying process S4>
In the carrying-in process S4, the elevator rail 2 is carried into the hoistway 3, which is the space to be transported, while raising the elevator rail 2 from the state where it has fallen down on the loading surface 611. In the carrying-in process S4, the elevator rail 2 is raised by lifting the elevator rail 2 with the lifting machine 7.

The elevator rail 2 is lifted by the lifting machine 7 by operating the operating section 73 in the landing 4 to operate the lifting machine main body 72. That is, by operating the operation part 73 in the landing 4 and moving the hanging body 71 upward, the second end 2b of the elevator rail 2 is pulled up. As a result, the elevator rail 2 rises while rotating around the connecting shaft 632 in a direction in which the angle of the elevator rail 2 with respect to the loading surface 611 increases.

FIG. 9 is a configuration diagram showing the state of the member transporting device 1 when the second end 2b of the elevator rail 2 in FIG. 8 is being lifted up by the lifting machine 7. As shown in FIG. When the elevator rail 2 rises, the second end 2b of the elevator rail 2 is pulled into the hoistway 3, and the first end 2a of the elevator rail 2 is pulled toward the landing entrance 5. As a result, the connecting shaft 632 of the truck 6 is drawn toward the hall entrance 5 while following the first end 2a of the elevator rail 2. At this time, the operator 8 of the landing 4 moves the connecting shaft 632 in the direction closer to the landing entrance 5 by contracting the pedestal 61 while maintaining the position of the front end of the pedestal 61.

That is, in the carrying-in step S4, the elevator rail 2 is raised by operating the operating section 73 while retracting the pedestal 61.

In the carrying-in process S4, after raising the elevator rail 2, the elevator rail 2 is removed from the connecting shaft 632 while the elevator rail 2 is suspended by the lifting machine 7. Thereby, the elevator rail 2 is carried into the hoistway 3.

In such a member transporting device 1, the elevator rail 2 is connected to the pedestal 61 by a connecting shaft 632. When the elevator rail 2 is connected to the base 61 by the connecting shaft 632, the connecting shaft 632 is passed through the connecting hole 21 provided in the elevator rail 2. Therefore, it is possible to more reliably prevent the elevator rail 2 from slipping on the loading surface 611 and falling from the pedestal 61. Furthermore, when carrying the elevator rail 2 into the hoistway 3, the elevator rail 2 can be easily raised while the trolley 6 follows the elevator rail 2. Furthermore, by passing the connecting shaft 632 through the connecting hole 21 of the elevator rail 2 placed on the loading surface 611, the elevator rail 2 can be easily connected to the pedestal 61 by the connecting shaft 632. Thereby, the burden of transporting the elevator rail 2 can be reduced. Moreover, the working time when transporting the elevator rail 2 can be shortened.

Furthermore, the pedestal 61 is expandable and retractable in a direction intersecting the connecting shaft 632 and along the loading surface 611. Therefore, when the elevator rail 2 is carried into the hoistway 3, the pedestal 61 can be shortened while the connecting shaft 632 is moved following the elevator rail 2. Thereby, the pedestal 61 can be prevented from getting in the way during the transportation work of the elevator rail 2, and the burden of the transportation work of the elevator rail 2 can be further reliably reduced. In addition, the working time for transporting the elevator rail 2 can be more reliably shortened. Furthermore, the cart 6 can be stored with the pedestal 61 retracted. Thereby, the space for storing the member transporting device 1 can be saved.

Further, in a state where the elevator rail 2 is connected to the pedestal 61 by the connecting shaft 632, the elevator rail 2 is lifted up by the lifting machine 7. For this reason, the elevator rail 2 can be easily raised from the state where it has fallen down on the loading surface 611 by the driving force of the lifting machine 7. Thereby, the burden of transporting the elevator rail 2 can be further reliably reduced. In addition, the working time for transporting the elevator rail 2 can be more reliably shortened.

Further, the lifting machine 7 has an operating section 73 that can be operated at a position remote from the lifting machine main body 72. Further, the lifting machine main body 72 operates according to the operation of the operating section 73. Therefore, the operator 8 can operate the lifting machine main body 72 in the hoistway 3 at the landing 4 located outside the hoistway 3. Thereby, the operation of the truck 6 and the operation of the lifting machine 7 can be performed by one worker 8. Therefore, the number of workers 8 when transporting the elevator rail 2 can be reduced.

Moreover, in such a member transportation method, the elevator rail 2 is connected to the pedestal 61 by the connecting shaft 632 by passing the connecting shaft 632 through the connecting hole 21 in the connecting step S2. Therefore, it is possible to more reliably prevent the elevator rail 2 from falling from the pedestal 61. Further, the elevator rail 2 can be easily raised while the trolley 6 follows the elevator rail 2. Furthermore, the elevator rail 2 can be easily connected to the pedestal 61 by the connecting shaft 632. Thereby, the burden of transporting the elevator rail 2 can be reduced. Moreover, the working time when transporting the elevator rail 2 can be shortened.

Further, in the loading process S1, the pedestal 61 is extended, and in the carrying process S4, the elevator rail 2 is raised while the pedestal 61 is contracted. Therefore, the pedestal 61 can be contracted while moving the connecting shaft 632 following the elevator rail 2. Thereby, the pedestal 61 can be prevented from getting in the way during the transportation work of the elevator rail 2, and the burden of the transportation work of the elevator rail 2 can be further reliably reduced. In addition, the working time for transporting the elevator rail 2 can be more reliably shortened.

Moreover, in the connection step S3, the elevator rail 2 is connected to the lifting machine 7. Furthermore, in the carrying-in process S4, the elevator rail 2 is pulled up by the lifting machine 7. Therefore, the elevator rail 2 can be easily raised by the driving force of the lifting machine 7. Thereby, the burden of transporting the elevator rail 2 can be further reliably reduced. Furthermore, the time required for transporting the elevator rail 2 can be further reliably shortened.

Further, in the carrying-in step S4, by operating the operating section 73 at the landing 4 located outside the hoistway 3, the lifting machine main body 72 is operated to pull up the elevator rail 2. Therefore, the operation of the truck 6 and the lifting machine 7 can be performed by one worker 8. Thereby, the number of workers 8 when transporting the elevator rail 2 can be reduced.

Note that in the above embodiment, each slide member 612 has a cylindrical shape. However, the shape of each slide member 612 is not limited to this. For example, each slide member 612 may be a panel with a C-shaped cross-section. In this case, each slide member 612 is arranged with the open section of the slide member 612 facing the back side of the pedestal 61.

Furthermore, in the embodiment described above, the base 61 is expandable and retractable. However, the pedestal 61 does not have to be expandable and retractable. Even in this case, the elevator rail 2 can be connected to the pedestal 61 by the connecting shaft 632. In this case, by making the length of the pedestal 61 shorter than the length of the elevator rail 2, the trolley 6 can be moved while making the elevator rail 2 follow the connecting shaft 632. Thereby, the elevator rail 2 can be more reliably prevented from falling from the pedestal 61.

Further, in the embodiment described above, the member transporting device 1 includes the lifting machine 7. However, if the elongated member carried into the hoistway 3 is not a heavy object and the elongated member can be pulled up by a worker in the hoistway 3, the lifting machine 7 may not be provided.

Moreover, in the embodiment described above, the connection step S3 is performed after the loading step S1 and the connection step S2 and before the carrying-in step S4. However, the connection step S3 may be performed after the loading step S1 and before the connection step S2.

Moreover, in the embodiment described above, the connection step S3 of connecting the elevator rail 2 to the lifting machine 7 is included in the member transportation method. However, if the elongated member carried into the hoistway 3 is not a heavy object, the elongated member can be pulled up by a worker in the hoistway 3, so there is no need to perform the connection step S3. .

Further, in the embodiment described above, the mounting portion 63 is provided at the rear end portion of the pedestal 61. However, the position of the attachment part 63 with respect to the base 61 is not limited to this. For example, the attachment portion 63 may be provided at the center of the base 61. Even in this case, the distance from the connecting shaft 632 to the front end of the pedestal 61 can be changed by expanding and contracting the pedestal 61. Thereby, the pedestal 61 can be prevented from getting in the way during the transportation work of the elevator rail 2, and the burden of the transportation work of the elevator rail 2 can be reduced. Further, the trolley 6 can be stored with the pedestal 61 retracted, and the space for storing the member transporting device 1 can be saved.

Further, in the embodiment described above, the operation unit 73 communicates wirelessly with the lifting machine main body 72. However, it is not limited to this. For example, the operating section 73 may be connected to the lifting machine main body 72 via a cable so that the operating section 73 can perform wired communication with the lifting machine main body 72.

The configurations described in the embodiments described above are examples of the content of the present disclosure. Embodiments can be combined with other known techniques. It is possible to omit or change a part of the configuration of the embodiment without departing from the gist of the present disclosure.
