[0002]

2. Description of the Related Art Conventionally, as this type of load lifting / moving apparatus, there is, for example, Japanese Utility Model Publication No. 1-1578.
That is, an elevating frame that is raised and lowered by a pair of right and left elevating cylinders is provided on the vehicle body, and a spreader that can be raised and lowered is suspended by a first hoisting line and a second hoisting line inside the elevating frame. Is provided. One end of the first hoisting rope is fixed to the left fixing column, and the other end is fixed to the right end of the spreader via a first sheave and a third sheave provided on the elevating frame. One end of the second lifting line is fixed to the right fixing column, and the other end is fixed to the left end of the spreader via a fourth sheave and a second sheave provided on the lifting frame.

[0003] According to this, by raising the lifting frame with both lifting cylinders, the spreader is lifted and the load is lifted, and by running the vehicle body,
The cargo was being moved to the destination. By lowering the lifting frame with both lifting cylinders, the spreader was lowered and the load was lowered to the destination.

[0004]

However, in the above-mentioned conventional type, in order to laterally move the suspended load in the left-right direction, it is necessary to move the vehicle body in the left-right direction. For this reason, for example, in the case of unloading another load immediately next to the load unloaded on the ground, in order to finely correct the unloading position in the left and right direction, drive the vehicle body in the left and right direction each time It had to be done, so it was very troublesome and work efficiency was poor.

[0005] In addition, an error occurs in the amount of hoisting or unwinding between the first hoisting rope and the second hoisting rope, and the spreader may be inclined up and down. Further, when the vehicle body is run with the spreader lifted, the spreader may be rolled.

According to this, after the load is held by the holding device, the lifting and lowering sheave on one side and the lifting and lowering sheave on the other side are both lowered by both the lifting and lowering cylinder devices, so that the lifting and lowering body is connected to the first cable. Since the body is lifted by the body and the second cord, the load is lifted via the holding device. Thereafter, the load can be moved to the destination by running the vehicle body.
Further, by raising both the lifting sheave on one side and the lifting sheave on the other side by both lifting cylinder devices, the lifting body is lowered, and the load is lowered to the ground.

In addition, the load can be moved laterally between the two vertical frames by operating the traversing drive device and traversing the traversing body while the load is lifted as described above. With this, when the position of the load is delicately corrected in the left-right direction, it is sufficient to traverse the traversing body and move the load in the left-right direction while the vehicle body is stopped, and to move the vehicle body each time. However, the position of the load can be easily corrected. Therefore, it is possible to easily carry out work such as unloading and arranging another load immediately beside the already-discharged load, thereby improving work efficiency.

Further, in the invention according to claim 2, the holding device has a vertical axis centered by a turning device provided on the elevating body.
It is characterized by horizontal turning around the center .

Further, the invention according to claim 3 is characterized in that a synchronizer for synchronizing the hoisting and lowering of the first cable and the second cable is provided on the transverse body. According to this, since the hoisting and unwinding of the first cord and the second cord can be synchronized, an error in the amount of hoisting or unwinding of the first cord and the second cord can be eliminated, and therefore In addition, it is possible to prevent the elevating body from tilting up and down.

Further, according to a fourth aspect of the present invention, the vertical frame is provided with a pair of guide members which are located on both sides of the moving path of the horizontal body and guide the elevating body along the moving direction of the horizontal body. The apparatus is characterized in that a swing-stopping member is provided for contacting the two guide members and preventing lateral movement of the elevating body in a direction orthogonal to the movement path.

According to this, it is possible to prevent the lifting / lowering body from swaying in the direction orthogonal to the moving path of the traversing body due to the contact of the swing-stopping member with the guide member. Further, the invention according to claim 5 is characterized in that the vertical frame is formed in an inverted V shape when viewed from the running direction of the horizontal body.

Further, as shown in FIG.
On the top, a worker gets in and drives the vehicle
A cabin 51 for performing a raising / lowering operation and a lateral movement operation of 44 is provided.

The operation of the above configuration will be described below.
As shown by the imaginary line in FIG. 1, both the pinions 52 are rotated by the driving device 53 so that both the horizontal frames 46a and 46b project to both sides of the elevating frame 16, and the two holding arms 47a and 47b are separated from each other. Move to And both hooks 49
After the a and 49b are positioned on both outer sides of the core hole 48 of the coil 44, the two pinions 52 are rotated in the reverse direction to

The hooks 49a and 49b are moved in the directions approaching each other, and the hooks 49a and 49b are fitted into the core hole 48 as shown in FIG.

Then, as shown in FIG. 10, the piston rods 21a and 21b of the two lifting and lowering cylinder devices 18a and 18b are retracted to lower both the second sheave 22 and the seventh sheave 27, thereby obtaining the first sheave 22. The path A from the first sheave 20 to the second sheave 22 of the roller chain 14 and the path B from the sixth sheave 26 to the seventh sheave 27 of the second roller chain 15 correspond to the traverse garter 11.
Is fixed by the traversing cylinder device 12 (see FIG. 1), and is stationary. The path C from the second sheave 22 to the third sheave 23 of the first roller chain 14 and the seventh sheave 27 of the second roller chain 15 are fixed. The path D from the first sheave 28 to the eighth sheave 28 is pulled downward, so that the elevating frame 16
The coil 44 is lifted by the roller chain 15, and the coil 44 is lifted via the lifter 45.

The traversing cylinder device 12 (see FIG. 1)
By actuating, the traversing gutter 11 can be moved laterally in the left-right direction, and the coil 44 can be moved laterally between the vertical frames 8a and 8b. That is, by retracting the piston rod 34 (see FIG. 1) of the traversing cylinder device 12, the traversing gutter 11
It moves rightward while being supported and guided by the rail member 10 via 17. At this time, the first roller chain 14 is
Girder as much as the distance between the sheave and the fifth sheave 25 is shortened
Since it is fed between 11 and the first sheave 20, the change in the distance between the traverse garter 11 and the first sheave 20 and the change in the distance between the fourth sheave 24 and the fifth sheave 25 cancel each other. Is done. Similarly, the second roller chain 15 is fed between the ninth sheave 29 and the tenth sheave 30 by an amount corresponding to a decrease in the distance between the traverse garter 11 and the sixth sheave 26. Change in distance to sheave 26 and ninth
The change in the distance between the sheave 29 and the tenth sheave 30 cancels each other. Therefore, as shown in FIGS. 10 and 11, when the traverse
The 16 levels will not change. Further, the piston rod 34 (see FIG. 1) of the traversing cylinder device 12 is protruded,
Similarly, when the traverse gutter 11 is moved to the left, the level of the lifting frame 16 does not change.

After the coil 44 is lifted as described above, the vehicle body 1 can be moved to move the coil 44 to the destination. Then, as shown in FIG. 12, the piston rods 21a, 21b of the two cylinder devices 18a, 18b for lifting and lowering.
By raising the b and projecting both the second sheave 22 and the seventh sheave 27, the lifting frame 16 is lowered and the coil 44 is lowered to the ground. After that, both the pinions 52 are rotated by the driving device 53 to move the two holding arms 47a and 47b away from each other, and the two hooks 49a and 49b are disengaged outward from the core hole 48 of the coil 44. As a result, the lifter 45 is separated from the coil 44.

The traverse garter 11 is traversed as described above,
When the position of the coil 44 is delicately corrected in the left-right direction by moving the coil 44 laterally between the two vertical frames 8a and 8b, the traversing garter 11 is traversed while the vehicle body 1 is stopped, and the coil 44 is moved left and right. In this case, the coil 44 can be easily corrected without having to move the vehicle body 1 each time. Therefore, work such as placing another coil 44 (shown by a solid line in FIG. 12) immediately adjacent to the coil 44 (shown by a phantom line in FIG. 12) that has already been dropped on the ground can be easily performed, and work efficiency can be improved. Is improved.

Further, since both vertical frames 8a and 8b are formed in an inverted V-shape when viewed from the side, the load caused by acceleration / deceleration generated when the coil 44 is lifted or hung compared to the case where a portal-shaped vertical frame is used. On the other hand, the strength is strong, and the use amount of steel can be reduced.

In the above embodiment, the first and second roller chains 14, 15 are used as an example of the first and second cords, but wires may be used. Further, although the coil 44 is described as a load, a container may be used. Further, as an example of the traversing drive device, the traversing cylinder device 12 is illustrated as shown in FIG. 1, but the rack provided on the rail member 10 side and the traverse garter 11

Further, a synchronization chain 68 is wound between the twelfth sheave 64 for synchronization and the thirteenth sheave 65 for synchronization, which are opposed to each other in the moving direction X of the traverse garter 11 (that is, the horizontal direction X).

As shown in FIGS. 17 and 18, the vertical frame 8
A pair of rectangular tubular reinforcing members 69 are provided between the front and rear sides of the moving path 70 of the traverse garter 11 between a and 8b. The reinforcing members 69 are provided with guide members 71 for guiding the lifting frame 16 from both front and rear sides in the moving direction X of the traverse garter 11. Also, lifter
On both sides of each holding arm 47a, 47b of 45, the lifting frame 16 swings in the direction Y orthogonal to the moving path 70 of the traverse garter 11 (that is, the front-back direction Y) by contacting the two guide members 71. An anti-swing member 72 is provided to prevent the movement. These rocking members 72 are formed in a U-shape, and are located between the guide members 71 when the lifting frame 16 is raised to a predetermined lifting height L.

As shown in FIG. 19, the lifter 45 is vertically moved by a turning device 74 provided on the lifting frame 16.

That is, the elevating frame 16 is divided into an upper frame portion 16a where the first roller chain 14 and the second roller chain 15 are connected and a lower frame portion 16b provided with the lifter 45. The lower frame portion 16b is rotatably supported about a vertical axis 75 horizontally via a support shaft 76 which extends downward from the upper frame portion 16a. The upper frame 16a is provided with a motor 77 for rotating the lower frame 16b, and a rotation driving sprocket 78 attached to the rotation shaft of the motor 77 is provided on the upper outer peripheral surface of the lower frame 16b.

The operation of the above configuration will be described.

As shown in FIG. 13, both hooks 49 of the lifter 45
After the a and 49b are inserted into the core hole 48 of the coil 44, the piston rods 21a and 21b of the two lifting cylinder devices 18a and 18b are retracted to lower both the second sheave 22 and the seventh sheave 27. As a result, the lifting frame 16 is
And the second roller chain 15, and the coil 44 is lifted via the lifter 45.

At this time, as shown in FIGS. 13 and 14, by providing the eleventh sheave 63 for synchronization, the fifth sheave 25 and the
Since the direction of rotation with the 10 sheave 30 is the same,
The 12 sheave 64 and the thirteenth sheave 65 for synchronization rotate in the same direction. Here, since the twelfth sheave 64 for synchronization and the thirteenth sheave 65 for synchronization are interlockingly connected via the chain 68 for synchronization, they rotate accurately in synchronization with each other.
The sheave 30 rotates accurately synchronously. Therefore, since the winding of the first roller chain 14 and the second roller chain 15 can be accurately synchronized, the error of the winding amount of the first roller chain 14 and the second roller chain 15 can be eliminated, and the lifting and lowering during lifting can be performed. The frame 16 and the lifter 45 can be prevented from tilting up and down.

Further, as shown in FIG. 24, the piston rods 21a and 21b of the two lifting and lowering cylinder devices 18a and 18b are protruded to raise both the second sheave 22 and the seventh sheave 27, so that the lifting frame 16 Is lowered, and the coil 44 is lowered to the ground. At this time, similarly to the case of lifting, the rotation directions of the fifth sheave 25 and the tenth sheave 30 are in the same direction, and the twelfth sheave 64 for synchronization and the thirteenth sheave 65 for synchronization are accurately synchronized in the same direction. Because of the rotation, the fifth sheave 25 and the tenth sheave 30 rotate accurately and synchronously. Therefore, the first roller chain
Since the lowering of the first roller chain 14 and the second roller chain 15 can be accurately synchronized, the error of the lowering amount of the first roller chain 14 and the second roller chain 15 can be eliminated. The lifter 45 can be prevented from tilting up and down.

Further, as shown in FIG.
Is lifted to a predetermined lifting height L to lift the coil 44, the rocking member 72 is located between the two guide members 71.
In this state, when the vehicle main body 1 is moved in the front-rear direction Y or decelerated and stopped, the rocking member 72 becomes a guide member.
Since the lifting frame 16 and the lifter 45 are in contact with each other, the horizontal swing of the lifting frame 16 and the lifter 45 in the front-rear direction Y can be prevented. As a result, as shown in FIGS. 21 to 24, the coil 44 can be lifted and carried safely. The procedure for carrying the coil 44 is the same as in the first embodiment described above. Further, an elastic body such as rubber may be attached to the guide member 71 so as to absorb a shock when the rocking stopper 72 comes into contact with the guide member 71, or the guide member 71 itself may be made of an elastic body such as rubber. May be manufactured.

As shown in FIG. 19, when the motor 77 is driven to rotate the rotation driving sprocket 78, the lower frame portion 16b is horizontally rotated with respect to the upper frame portion 16a via the ring gear 79. Therefore, the lifter 45 horizontally turns around the vertical axis 75. With this, lifter 45
, The direction of the coil 44 suspended in the vehicle can be changed in the front-rear and left-right directions, so that it is not necessary to change the direction of the vehicle body 1 each time, and the coil 44 can be easily loaded on a truck or the like.

In the second embodiment, as shown in FIG. 20, the engine 6 and the cabin 51 are separated from each other before and after the vehicle body 1, so that the noise and the noise of the engine 6 transmitted into the cabin 51 are reduced. Vibration can be reduced. Also,
Since the cabin 51 is at the lower position, the work location becomes easier to see when the hooks 49a and 49b of the lifter 45 are inserted into the core hole 48 of the coil 44 or when the coil 44 is lowered to a predetermined position.
