A supporting shaft 12 is vertically provided at the center of the direction-changing rail receiving plate 11, and a direction-changing rail (I-shaped steel) 13 having a length slightly shorter than the predetermined gap is provided at the height of a lower end flange 13a thereof. Is rotatably supported by the lower end portion of the support shaft 12 in conformity with the lower end flange (for example, 2a) of another traveling rail.

Lower end flange 1 of the direction changing rail 13
The ring rail 7 is rotatably supported by a support member 14 having a U-shaped cross section and rotatably mounted on the vehicle 3a by a traveling tire 14a and a motor 14b. Then, the support member 14
A rotary gear 15 is fixedly attached to the lower surface of the drive gear 16, and a drive gear 16 is engaged with the drive gear 16 so as to rotate integrally with the rotary shaft of the motor 17. The motor 17 is fixed to the ring rail 7 side with a mounting member or the like.

In this way, the direction changing device 6 is constructed, and by rotating the motor 17, the rotary gear 15 rotates with respect to the ring rail 7, and the supporting member 14 and the direction changing rail 13 rotate with it. It is a thing.

Since the direction changing device 6 is arranged at four places as shown in FIG. 1, the rotating directions are reversed so that the couples due to the rotating force of the motor 17 cancel each other (in the figure, (Arrow direction), the ring rail 7 is the motor 17
It is intended to prevent rotation due to the couple of forces that accompany the rotation of.

Next, the circumferential moving device 8 is for rotatably attaching the hoisting traveling rail 9 to the ring rail 7, and as shown in FIGS. 2 and 4, the lower end of the ring rail 7 is moved.

Then, as shown in FIG.
Is movable in the longitudinal direction of the hoisting travel rail 9, so that the entire inside surrounded by the ring rail 7 is the range of lifting work.

Further, by making the hoisting traveling rail 9 longer than the diameter of the ring rail 7, a hoisting work range exceeding the range of the ring rail 7 can be achieved.

Reference numeral 21 shown in FIGS. 3 to 4 indicates a positioning sensor provided at the center of the direction changing rail 13, and the support member 14 rotatably supporting the ring rail 7 runs. Then, when the traveling control device (not shown) of the support member 14 is in the direction changing mode when reaching the central portion of the direction changing rail 13, the positioning sensor 21 reacts to move the vehicle. Motor 14
The rotation of b is stopped.

A method of using the hoist moving apparatus 1 thus formed will be described. The ring rail 7 is attached to the traveling rails 2, 3 or 4, 5 which are erected on the beams of a building or an underground structure. In order to linearly move in one direction, a traveling control device (not shown) is remotely operated to drive / rotate the motor 14 to rotate the traveling tire 14a to move it via the support member 14.

Next, in order to move the ring rail 7 laterally from, for example, the traveling rails 2 and 3 to the traveling rails 4 and 5, the direction control mode is set in the traveling control device and the supporting member 14 is moved to the remote position. Operate it to run. And
When the support member 14 reaches the central portion of the direction changing rail 13, the positioning sensor 21 reacts to stop the driving of the motor 14b of the support member 14, and then the motors 17 in the direction changing devices 6 at four locations are driven. Rotate in the given direction.

The rotation direction of the motor 17 is such that the ring rail 7 is not rotated by a couple force, and as shown in FIG. 1, the ring rail 7 is rotated so as to cancel the couple force generated by the rotation of the motor 17.

Then, as shown in FIG. 5, the direction changing rail 13 is rotated at a substantially right angle to be positioned linearly with the traveling rail 4 or 5.

At this time, when the direction changing rail 13 is rotated at a substantially right angle, it is mechanically locked at that position, and the positioning switch is controlled so that the rotation of the motor 17 is automatically stopped. Is preferred.

The direction changing rails 13 of the four direction changing devices 6 are all traveling rails 4 and 5 as shown in FIG.
When it becomes a straight line, the motor 14b is again remotely driven via the traveling control device to drive the support member 14, and the ring rail 7 is moved in the orthogonal direction from the left direction of the drawing to the upper or lower direction of the drawing. It is what makes me.

In this way, the ring rail 7 is moved vertically and horizontally to the traveling rails 2, 3 or 4, 5 and the hoist traveling rail 9 suspended on the ring rail 7 is rotated in the horizontal plane. As a result, the hoist 10 can be used, and as shown in FIG. 7, the range of a and b between columns in a building can be covered and a wide range over almost the entire range can be covered as a lifting work range.

Even if a plurality of hoisting moving devices 22 are suspended by the power supply device 23 on traveling rails 2, 3, 4, 5 vertically and horizontally, each moving device 22 can move independently. Therefore, it is not necessary to wire the power supply cables to the traveling rails 2 and 3 in a complicated manner and to supply the power supply cable to the moving device 22, which results in a simple configuration.

Further, as shown in FIGS. 11 to 12, the direction changing rails 24 of the direction changing device 6a in the hoist moving device 22 face each other with a cross-shaped direction changing rail receiving plate 26 cut off. Running rails (eg,
The support shaft 25 is erected on the traveling rail 2 and the traveling rail 4 which is orthogonal to the traveling rail 2 and is fixed by welding. And is stuck.

Further, the joint between the support shaft 25 and the four direction changing rails 24 is joined only at the upper portion, and the other central portion and lower portion are cut off to form the supporting member 2.
The shape is such that a passage area is secured so that 7 can come and go in both front, rear, left and right directions.

Under the support shaft 25, the relay rail 24a extends in the direction of the direction change rail 24 so that the traveling tires 28, 29, 30, 31 of the support member 27 do not slip off. A total of four places are fixed in a cross shape.

As shown in FIG. 12, the traveling tires 28, 29, 30, 31 of the supporting member 27 are arranged such that the traveling tires 28, 28 and the traveling tires 29, 29 are opposed to each other. 30 and 31 are arranged so that their positions are shifted.

Since the support member 27 moves forward, backward, leftward, and rightward on the four direction changing rails 24, the traveling motor 32 of the supporting member 27 has a direction changing rail 24 and a relaying rail as shown in FIG. It is installed with a gap below 24a so as not to collide with them.

The direction changing rail 24 is shown in FIG.
As shown in FIG. 6, the motor 33 for the direction changing device 6a rotates about 90 ° in a predetermined direction via the rotary table 34 and the support device 27. Therefore, the electric sensor 35, The stopper 36 and the stopper rod 36a are attached to the rotary table 34 and the supporting steel material 3

Then, two click devices 39 are provided at positions on the positioning band plate 24c in the directions orthogonal to each other of the direction changing rail receiving plates 26, 26.

The click device 39 is provided with a rolling element 39a that rolls on the upper surface of the positioning band plate 24c, is urged downward by a coil spring 39b, and is vertically movable. Then, the rolling element 39a falls into the groove at the position of the V groove 24d, and a click feeling is obtained.

Next, as shown in FIG. 15, the arc-shaped entrance blocking plate 40 arranged so as to ensure the passage of the supporting member 27 from the rotation reinforcing plate 24b of the direction changing device through the suspending member 40a is provided. It is placed in various places and hung up.

When each of the direction blocking rails 24 is in a linear state with respect to the vertical and horizontal traveling rails by the respective entry blocking plates 40, the vertical and horizontal passage of the supporting member 27 of the direction shifting device is not hindered. , One support member 2
The motor 7 supports the support member 27 and the direction changing rail 24 to change its direction.
When the rotation reinforcing plate 24b is rotated, the entry blocking plate 40 is also rotated together with the rotation reinforcing plate 24b, and the traveling paths of the traveling rails 2 and 4 are all blocked.

Therefore, when the supporting member 27 enters the direction changing rail 24 at one place, the supporting members of the other hoist moving devices cannot enter.

Further, due to a malfunction or the like, the direction changing rail 24
When the traveling rails 2, 3, 4, 5 are not straight,
The support member 27 is mounted on the entrance blocking plate 40 so that the direction change rail 2
4 is prevented, and the support member 27 is prevented from falling off.

Further, as shown in FIG. 15, in the turning device, the motor 32 is driven by an erroneous operation while the supporting member 27 enters the running rail 24 to change the direction, and the running tires 28, 29, 30, 31 are moved. When the support member 27 rotates and rotates, the support member 27 may fall off the traveling rail 24. Therefore, as a means for preventing the support member 27 from falling off the traveling rail 24, the arc-shaped safety cover 41 serves as a support member. Secure the movement along the traveling rails 2 and 4, and
It is placed and suspended at various places.

The safety cover 41 may be supported from the direction change rail receiving plate 26 by a supporting steel material or the like,
It may be supported from the upper portions of the traveling rails 2 and 4, and the point is that a fixing plate serving as a stopper may be used so that the supporting member 27 during the direction change does not fall off the direction change rail 24. Therefore, the entrance blocking plate 40 rotates together with the rotation reinforcing plate 24b, but the safety cover 41 is fixed in position.

Thus, in the hoist moving device 22 according to the second embodiment, the traveling rails 2, 3, 4, 5 of the cross-shaped turning rail 24 are used in the turning device.
The rotation positioning with respect to is accurately performed with a click feeling, and in terms of safety, the entry blocking plate 40 blocks entry of the support member 27 when the traveling rail and the direction changing rail are not in a straight line, which is safe. The cover 41 prevents the support member 27 from falling off the direction changing rail 24.
