Description

[Detailed Description of Device] a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet lifting device, which is used by mounting it on a hanging beam of a crane together with other lifting device.

B. Conventional technology Steel products such as steel rods and pipes, and other long objects are transported and stored by a suspension device that uses vacuum, magnetism, hydraulic pressure, pneumatic pressure, etc. as a storage device, and steel products are placed on pallets. A device that suspends and conveys pallets with a crane suspension device and stacks and stores them with a pallet, or a device that uses these pallets and that can automatically operate connection and disconnection between the suspension device and the pallet using a crane. Further, a device provided with a riff mag device and a pallet suspension device has been proposed. Mitsuko Sho 63-18481.

C. Problems to be solved However, in this case, since the lifting device or the pallet lifting device is attached to one beam, when one is used, the other becomes an obstacle to slinging work. A rotating mechanism to the top was commonly used. These mechanisms have problems such as complicated structure and taking up too much space. When using each device together, it is necessary to move the crane itself when connecting and disconnecting the lifting device and slings for products or the pallet lifting device and the loading platform. This is because, in the case of the pallet suspension device, when suspending the support arm for suspension on the hook, it is necessary to raise the support arm and move the support arm into the hook. The operation of moving the crane, especially the small movement, is troublesome, and in particular, such as the connection of the support arm and the hook requires careful attention so as not to generate an impact, so it is difficult to operate only with the cab,
This is where other manual or other verification devices are required. Further, the lifting device and the pallet lifting device may shake and collide with products, structures and the like.

D. In the present invention, therefore, the pallet lifting device can be folded and stored at the upper part, and obstacles at the time of lifting device operation such as riff mug are removed to improve work efficiency. And
Just as the crane is moved to the top of the pallet, the suspension device and the pallet are automatically connected, so that the suspension device can be automatically adjusted in position with respect to the pallet during the connection. The pallet is connected and disconnected only by the operation of the crane operator without applying the full weight of the beam to the pallet, and it is extremely efficient without manpower. A plurality of shafts supported by is engaged with the timing gear,
A suspension device consisting of an arm and a telescopic arm is supported at both ends of both shafts by pins orthogonal to the longitudinal direction of the shaft, while a frame provided with a lower end of the arm and a telescopic arm, a lower end of the telescopic arm and a pallet engaging portion is respectively provided in the axial direction. It is pivotally supported by a pin, a shaft rotation mechanism is provided by a cylinder, and further, a protruding piece is provided on the arm in the axial direction, and the movable beam is pressed via a ridge for a steady rest in the coaxial direction. .

22 is engaged. The pin 20 and the pin 21 are respectively inserted in the direction of the shaft 16, and the pin 17 is inserted in the shaft 16 in the direction orthogonal to the pins 20 and 21. Reference numeral 23 is a lever fixed to the rotating shaft 16 and engages with a fork end 24 at its tip, and is connected to a cylinder 26 such as air or oil attached by a mounting bracket 27 via a rod 25. It constitutes the rotating mechanism. Reference numeral 28 denotes a steady rest unit, which is formed by pressing a projecting piece 29 provided on the arm 15 against the moving beam 12 by a spring 30. A groove 31 through which the locking portion 4 is inserted is formed in the engaging portion 19, and guide plates 32, 32 which are expanded downward are extended.
The suspension pin 34 provided on the rod 33 is moved in and out by the operation of a cylinder of air, oil, or the like, and is inserted into the hole 3 of the engaging portion 4 which enters the engaging portion 19 . Reference numeral 35 is a riff mag as a hanging device, which is used when the hanging device 13 is not used. The riff mag 35 is a moving beam
It is suspended by a chain 37 suspended from a hanger 36 provided at 12.

Next, the operation will be described.

When the lifting device 13 is not used and the riff mag 35 is not used, when the cylinder 26 of air, oil, or the like is operated, the rod 25 thereof expands and presses the lever 23 via the fork end 24. The movement of the lever 23 causes the shaft 16 to rotate. At that time, the arm 17 pivotally supported by the shaft 16 is rotated by the pin 17 and is raised. By this rotation of the shaft 16, the other shaft 16 is also rotated by the meshing of the timing gears 22, 22 and is rotated outward and upward. Therefore, the adjacent arms 15 and 15 are simultaneously turned upward and rotated. At the same time, telescopic arm 1 via pins 21 and 21
The arms 4 and 14 cannot be expanded because the upper parts of the arms 14 and 15 are expanded and raised, and the lower parts of the arms are supported by the pins 20 and 20 to support the frame 18 . Therefore, the arms 15, 15 ... The telescopic arms 14, 14 ... Ascend while keeping the central portions open and the upper and lower sides closed to raise the frame 18 . At that time, the riff mag 35 is located below the engaging portion 19 of the frame 18, and the steel material 40 can be adsorbed and lifted and conveyed without hitting the frame 18 and the engaging portion 19 . Also, when the riff mag 35 is not used, the pallets 1 , 1 are suspended by the suspension devices 13 , 13 . That is,
The pallets 1 and 1 are arranged at appropriate intervals, and the steel material 40 is placed on both pallets 1 and 1 . Crane 5 during transportation
By moving the trolley 6 and the extensible beam 7 , that is, the movable beams 12, 12 relative to the main beam 8, the suspension devices 13 , 13 are spaced apart from each other so that the pallets 1 , 1 , the interlocking portion 4 are interlocked.
According to the interval. In this way the suspension device 13 , 13
When the pallets are brought onto the pallets 1 , 1 , the hoisting device of the trolley 6 is operated to lower the telescopic beam 7 , and the hanging devices 13 , 13 are lowered. At that time, the engaging portions 19 , 19 provided on the frame 18 at the lower end of the suspension device 13 are positioned corresponding to the pallets 1 , 1 , and the locking portion 4 of the pallet 1 is fixed by the guide plate 3
Guided by 2 and 32, it enters the groove 31. At this time, when the position of the locking portion 4 hits the guide plates 32, 32 and is disengaged from the groove 31 in the middle, the frame 18 receives the moving pressure via the guide plates 32, 32. The pressure is transmitted to the arms 15, 15 ... via the expansion radiuses 14, 14 ..., and at that time, the arms 15, 15 ... Are rotated about the pins 17, 17 ... Therefore, the frame 18 is also moved, and as a result, the locking portion 4 enters the groove 31. That is, the groove 31 to be inserted by the locking portion 4 achieves the movement of the frame 18 without finely adjusting the positions of the suspension devices 13 , 13 . Then the frame
By the movement of the one of 18, arm via a telescoping arm 14
When 15 is tilted, one of the protrusions 29 is pressed against the spring 30,
No pressure is applied to one of the projecting pieces, and the projecting piece 30 projects to press the moving beam 12. Therefore, the arm 15 is allowed to incline through the frame 18 , and at the same time, the arm 15 suppresses the incline, and further the repetitive shake.

F. According to the present invention as described above, a plurality of shafts supported in a direction orthogonal to the longitudinal direction of the moving beam are meshed with a timing gear, and both ends of the shaft are composed of arms and telescopic arms. While the suspension device is supported by pins that are orthogonal to the longitudinal direction of the shaft, a frame having an arm lower end and a telescopic arm, and a frame equipped with a telescopic arm lower end and a pallet engaging portion are pivotally supported by the axial pins, respectively, and a shaft formed by a cylinder is used.
