In the figure, "X" represents the front-rear direction, "Y" represents the up-down direction, and "Z" represents the width direction.

The transport carriage 30 has a function of transporting a substantially rectangular parallelepiped housing box L elongated in the front-rear direction X, which houses the elongated control cable 22 in a spiral shape. The control cable 22 bundle housed in the housing box L is mounted on the transport carriage 30 (see fig. 5) in an upright state in which the scroll axis is horizontal. As shown in fig. 2, the transport vehicle 30 is composed of a front base 32 and a rear base 34 divided into front and rear portions. Since the front chassis 32 and the rear chassis 34 have the same configuration, only the configuration of the front chassis 32 will be mainly described in the following description, and the description of the configuration of the rear chassis 34 will be omitted as appropriate. As shown in fig. 3 (a), a rotation support plate 35 is attached to a lower portion of the front base 32. The rotation support plate 35 is attached to the lower surface of the front base 32 via a rotation shaft 35 a.

Casters

36 and 37 with stoppers are rotatably attached to both front and rear ends of the rotary support plate 35.

A stop slide bar 36a, 37a is provided on the upper portion of each

caster

36, 37, and the slide bar 36a, 37a is slid in the circumferential direction to brake the

caster

36, 37 so as not to rotate. This makes it possible to fix the transport carriage 30. The

casters

36 and 37 are rotatably supported by the front base 32 via a rotary support plate 35.

The transport carriage 30 includes a belt roller support 40 that rotatably supports the control cable 22 bundle, and a fixing arm 50 that fixes the storage box L to the transport carriage 30.

As shown in fig. 2, the belt roller support 40 includes a support 42 fixed to the front base 32 and a plurality of rollers 44a to 44e attached to an upper portion of the support 42. The support 42 has two panels 42a and 42b arranged to face each other to form two side surfaces. The upper end surfaces of the panels 42a and 42b are curved downward in the front-rear direction X in a concave shape. The front surface panel 42c is disposed so as to connect the front ends of the panels 42a and 42 b. The upper end surface of the support 42 is formed in a substantially arc shape as a whole together with the support 42 and the support of the rear base 34, and the height of the central portion in the front-rear direction X is formed to be lower than the height of the front and rear ends of the transport carriage 30.

The plurality of rollers 44a to 44e are rotatably attached along the curve of the upper end surface of each of the panels 42a and 42 b. The upper portions of the outer peripheral surfaces of the rollers 44a to 44e protrude from the upper end surfaces of the panels 42a and 42b and are exposed. In the present embodiment, five rollers 44a to 44e are provided, but the number of rollers is not limited to five. Further, a slit 42d that is long in the vertical direction Y is provided at the lower portion of the side surface of each of the panels 42a and 42 b. A fixing pin 46 functioning as a rotation stopper of the rotation support plate 35 is engaged with the slit 42d so as to be movable in the vertical direction Y.

As shown in fig. 2, the fixing pin 46 is supported by a support 47 provided on the upper surface of the front base 32 so as to be movable in the vertical direction Y, and penetrates through the through hole 32a of the front base 32 and one of the

fixing holes

35b and 35c (see fig. 3 a and 3 b) of the rotation support plate 35, thereby functioning as a rotation stopper of the rotation support plate 35. More specifically, as shown in fig. 3 (a), when the fixing pin 46 is inserted into the fixing hole 35b, the rotation support plate 35 including the

casters

36 and 37 is fixed in a state of being accommodated in the front base 32 directly below. This allows the transport vehicle 30 to be laid down in a flat state. On the other hand, as shown in fig. 3 (b), if the rotation support plate 35 is rotated by about 90 degrees and the fixing pin 46 is inserted into the fixing hole 35c, the rotation support plate 35 is fixed in a state of being spread in the width direction Z. This enables the front base 32 to be self-standing.

As shown in fig. 3 (a) and 3 (b), a plate-like coupling metal fitting 48 is attached to the lower surface of the front end portion of the rear base 34. Two

bolts

48b and 48c are attached to the connection fitting 48 so as to penetrate in the vertical direction Y.

Long holes

32b and 32c are provided in the rear end portion of the front base 32 at positions corresponding to the two

bolts

48b and 48c, and the

bolts

48b and 48c are inserted through and fixed to the two

long holes

32b and 32c, respectively. This allows the front base 32 and the rear base 34 to be coupled so that the length in the front-rear direction X can be adjusted. As a result, the overall length of the transport carriage 30 can be adjusted in accordance with the plurality of types of containers L having different lengths in the front-rear direction X.

As shown in fig. 2, the fixing arm 50 is constituted by a pair of

corner members

52, 54 extending in the vertical direction Y, the corner member 52 is erected on the upper surface of the front end portion of the front base 32 in the vertical direction Y, the corner member 54 is erected on the upper surface of the rear end portion of the rear base 34 in the vertical direction Y, the corner member 52 is formed by an L-shaped member constituted by a 1 st wall portion 52a abutting on the front surface of the housing box L and a 2 nd wall portion 52b abutting on the side surface of the housing box L adjacent to the front surface, the corner member 52 is disposed so as to face the support body 42 with a gap α therebetween, and similarly, the corner member 54 is formed by an L-shaped member constituted by a 3 rd wall portion 54a abutting on the rear surface of the housing box L and a 4 th wall portion 54b abutting on the side surface of the housing box L adjacent to the rear surface.

Further, it is preferable that a handle 52c and a handle 54c are provided on the outer side surface upper portions of the 1 st wall portion 52a and the 3 rd wall portion 54a of the

corner members

52 and 54, respectively. Thus, the maintenance worker can easily move and raise the transport cart 30 by gripping the

handles

52c and 54 c.

As shown by the chain line in fig. 2, one corner portion of the front end side of the storage box L extending in the vertical direction Y is inserted into the gap α, and the corner portion located on the opposite side to the rear end side of the storage box L is similarly inserted into the gap between the corner member 54 and the support body 42.

Next, a method of transporting and mounting the control cable 22 using the transport vehicle 30 will be described with reference to fig. 4 to 6.

As shown in fig. 4, the serviceman places the storage box L on the ground in a flat state, and cuts the bottom surface of the storage box L with a cutter or the like, for example, to form an open end L1. Next, the corner portions at the front and rear ends of the open end L1 are inserted into the gaps between the belt roller support body 40 and the front and

rear corner members

52 and 54, respectively. Thereafter, the

handles

52c and 54c provided on the fixing arm 50 are gripped, and the storage box L is directly pulled up in a state of being fixed to the transport carriage 30. Then, the rotation support plate 35 is rotated by 90 °, the fixing pin 46 is inserted into the fixing hole 35c and fixed (see fig. 3 b), and the transportation vehicle 30 is made self-standing in a stable state as shown in fig. 5.

Subsequently, the maintenance worker pushes and moves the transport cart 30, and carries the cart into the car 14. Then, the elevator control panel 20 of the machine room M is operated by remote operation from the inside of the car, and the boarding car 14 is raised to a position close to the cable hook 21. Thereafter, the upper end portion of the storage box L is cut and opened by a cutter or the like, one end of the control cable 22 is pulled out, and the control cable 22 is sent out into the hoistway S from the rescue hatch 19 of the boarding car 14. At this time, it is preferable to brake the

casters

36 and 37 in advance by sliding the slide bars 36a and 37 a. Similarly, it is preferable that the caster of the rear base 34 is also braked in advance. This prevents the transport carriage 30 from moving when the control cable 22 is fed out.

Then, as shown in fig. 6, one end of the control cable 22 is connected to the cable hook 21, and the elevator control panel 20 is remotely operated to gradually lower the car 14. At this time, the control cable 22 stored in the storage box L is fed out from the storage box L by the rotation of the spiral control cable 22. When the car 14 descends to the pit P, the other end of the control cable 22 is connected to the connection port 14a provided at the lower end of the car 14. This enables the control cable 22 to be attached. When a plurality of control cables 22 are to be attached, the above-described attaching operation may be repeated.

According to the transport cart 30 with the elevator control cable feeding function of the above embodiment, the storage box L is fixed to the transport cart 30 in the standing state by the fixing arm 50, and the spiral control cable 22 bundle can be fed out while being rotated as the control cable 22 is pulled out from the storage box L. Therefore, the spiral control cable 22 can be sent out from the storage box L without a step of temporarily taking out the spiral control cable 22 from the storage box L and transferring the control cable to the transport cart 30. As a result, the work of attaching the control cable 22 can be efficiently performed.

In the above embodiment, the support body 42 is bent downward along the front-rear direction X of the transport carriage 30, but the upper edge portion of the support body 42 does not necessarily have to be bent, and the outer peripheral surfaces of the plurality of rollers 44a to 44e may be exposed to protrude from the upper edge portion of the support body 42.

In the above embodiment, the fixing arm 50 is formed of the pair of

corner members

52 and 54 provided at both front and rear ends of the transport carriage 30, but is not limited thereto. For example, a pair of flat plate members or rod members may be erected on both front and rear ends of the transport carriage 30.

It is needless to say that the present invention is not limited to the configurations of the above-described embodiments and modifications thereof, and various improvements and modifications can be made within the scope of the items described in the claims of the present application and their equivalents.
