[Prior art]
In recent years, incineration treatment has become mainstream in the disposal of industrial waste due to difficulties in securing land for a landfill disposal site associated with landfill treatment and environmental pollution. When incinerating industrial waste in this way, chemicals such as waste oil, waste paint, waste paint, solvent, etc., which are handled in a closed state, particularly in industrial waste, packed and sealed in containers such as drums Combustible waste including waste and heavy metals, or business-related industrial waste such as medical waste is difficult to handle, so after handing these industrial waste in a drum can, Sealed waste incineration facilities have been developed as waste treatment facilities that allow incineration treatment in a completely sealed state without intervention.
[0003]
This type of sealed waste incineration facility is shown in FIG. 7 as schematically showing an example thereof, below a waste charging hopper 1, a crusher 2 such as a biaxial crusher, a mixer 3, and a pressure feed pump 4 such as a piston pump. Are connected in order from above so that the sealed state can be maintained, and an incinerator 5 such as a rotary kiln is connected to the pressure feed pump 4 through a transport pipe 6 in an airtight manner, in the hopper 1 and in the drum 7. The industrial waste packed and carried in is put together with the drum 7 without opening the lid of the drum 7, the drum 7 is crushed by the crusher 2, and the industrial waste is taken out at the same time. It can be crushed to a fine size that does not hinder kneading by the subsequent mixer 3 or the pumping pump 4, and the crushed material can be kneaded (mixed) by the mixer 3 and pumped. After making the uniform high-viscosity waste 8 into a shape, the high-viscosity waste 8 is pumped through the transport pipe 6 by the pumping pump 4 to be put into the incinerator 5 and incinerated in the incinerator 5. It is.
[0004]
Moreover, in the above-mentioned sealed waste incineration facility, in order to use the general waste 9 such as garbage as a transport auxiliary medium (carrier) for industrial waste, the general waste 9 is put into the hopper 1 together with the industrial waste. In this case, since the hopper 1 is installed at a high position to connect the crusher 2, the mixer 3, and the pressure pump 4 to the lower side, the general waste 9 is conveyed. A container lift 10 is installed as a device for feeding the object to the hopper 1 after being transported so as to be lifted up to a high place.

The lift cage 12 is provided with a mechanism (not shown), and the lift cage 12 is moved upward by a left and right side wall 14 and a rear side wall 15 on a frame 13 having a size on which a container can be placed as shown in FIG. As shown in FIG. 7, the lower end portion of the guide rail 11 is formed by a lifting drive device as shown in FIG. The container 17 containing the general waste 9 as the object to be transported is loaded and placed in the space 16 of the lift cage 12 lowered by the forklift or the like, and the lift cage 12 is moved by the elevating drive device to the guide rail 11. And lift the container 17 integrally with the lift cage 12, and when the lift cage 12 reaches the upper end of the guide rail 11, the lift cage 12 is tilted backward by the cage tilting mechanism, As a result, the container 17 stored in the space 16 is tilted rearward together with the lift cage 12, and the general waste 9 stored in the container 17 is discharged by its own weight to be loaded into the hopper 1. I am trying to make it.
[0006]
In the sealed waste incineration facility, the general waste 9 may be loaded on the pallet 18 and handled together with the pallet 18 such as transport and accumulation. When it is desired to put the item 9 into the hopper 1, the pallet 18 loaded with the general waste 9 is loaded into the space 16 of the lift cage 12 and placed on the frame 13. In the same manner as described above, the lift cage 12 is raised and then tilted to the hopper 1 side, so that the general waste 9 placed on the pallet 18 is discharged by its own weight so as to be loaded into the hopper 1. It is.
[0007]
[Problems to be solved by the invention]
However, the container lift 10 tilts the lift cage 12 to discharge the general waste 9 stored in the container 17 and the general waste 9 loaded on the pallet 18. Therefore, in order to reuse the container 17 and the pallet 18 after being transported, the container 17 and the pallet 18 are held in the lift cage 12 so that the container 17 and the pallet 18 do not fall into the hopper 1 even when the lift cage 12 is tilted. It is necessary to let

[0021]
Further, after the container 17 is placed on the frame 13, it can be fixed only by operating the clamp device 21 on the front end surface of the frame 13, and the clamp device 21 rotates the clamp arm 22 upward. After the distal end of the clamp arm 22 is inserted into the fork insertion hole 20 of the container 17 placed on the frame 13, the slide operation of the lock pin 24 as the first lock mechanism, and the second Since the clamp arm 22 can be easily locked by screwing the nut member 29 of the lock mechanism 26 to the lock bolt 28, the container 17 placed in the space 16 can be easily fixed.
[0022]
Next, FIGS. 4 to 6 (a) show another embodiment of the present invention, which includes an engaging protrusion 19 and a clamping device 21 as in the lift cage device shown in FIGS. The pallet adapter 31 is placed on the frame 13 of the lift cage body I having the above-described configuration, and the pallet adapter 31 is supported by the engaging projection 19 and the clamp device 21 and placed on the pallet adapter 31. The pallet 16 is held by a pallet adapter 31 and a cross bar 35 engaged with the cage body I. That is, a crossbar insertion groove 34 that extends in the horizontal direction in the front-rear direction is formed symmetrically in the front position of the left and right side walls 14 of the lift cage body I, and the position of the crossbar insertion groove 34 is The position corresponds to the total height of the thickness of the pallet adapter 31 placed on the frame 13 of the lift cage body I and the thickness of the pallet 18 placed on the pallet adapter 31.
[0023]
The pallet adapter 31 has a pallet placement part 31a having a fork insertion hole 20a for inserting a fork of a forklift in a pallet shape having a required height in the front-rear direction, and an upper end on the upper surface of the rear end part of the pallet placement part 31a.

In this state, the clamp arm 22 of the clamp device 21 is inserted into the front end portion of the fork insertion hole 20a, and the clamp arm 22 is operated by sliding the lock pin 24 and screwing the nut member 29 to the lock bolt 28. The pallet adapter 31 can be fixed to the space 16 of the lift cage body I by being locked by the attaching operation.
[0024]
Further, when the pallet 18 is placed on the pallet placement portion 31a of the pallet adapter 31 and pressed against the engagement portion 33 of the rear end portion, the rear end portion of the pallet 18 is engaged by the engagement portion, and this state By inserting both ends of the cross bar 35 into the cross bar insertion grooves 34 provided on the left and right side walls 14 of the lift cage body I, the pallet 18 can be held by pressing the front end of the pallet 18. Like that.
[0025]
As shown in detail in FIG. 5, the crossbar 35 is slightly longer than the width dimension of the lift cage body I and has a slightly smaller diameter than the width dimension of the crossbar insertion groove 34 on both sides in the longitudinal direction. And a stepped portion 37 is formed outside the small-diameter portion 36 with both ends in the longitudinal direction outside the small-diameter portion 36 having a diameter larger than that of the crossbar insertion groove 34. The turnbuckle is configured so that the portion 37 can be locked to the outside of the crossbar insertion groove 34 and further provided with a turnbuckle mechanism 38 for expanding and contracting the entire length at a required position in the middle of the longitudinal direction. In a state where the mechanism 38 is loosened, the small diameter portions 36 formed at both ends in the longitudinal direction of the cross bar 35 are respectively inserted into the cross bar insertion grooves 34 on the left and right side walls 14 of the lift cage body I from the front. After inserting the small diameter portion 36 in the cross bar insertion groove 34 in the front-rear direction and placing the cross bar 35 at a required position in the front-rear direction, the turnbuckle mechanism 38 is tightened to increase the total length. By contracting, the stepped portion 37 formed outside the small-diameter portion 36 is locked to the outside of the crossbar insertion groove 34 and the left and right side walls 14 serving as the peripheral edge of the crossbar insertion groove 34 are The cross bar 35 can be fixed by pressing against the outer surface from the outside.
[0026]
In the above description, the thickness dimension of the pallet 18 that serves as a reference when setting the position of the crossbar insertion groove 34 and the height dimension of the locking member 32 of the pallet adapter 31 is the same as that of the normally used pallet 18. Among them, it is adapted to the dimension of the thickest pallet 18. Further, as shown by a two-dot chain line in FIG. 5, when a beam member 39 is provided at a position where it interferes with the crossbar insertion groove 34 on the outer surface of the left and right side walls 14 of the lift cage body I, the beam member 39 is provided with a notch 40 of a size through which the end of the crossbar 35 can pass. Other components that are the same as those shown in FIGS. 1 to 3 are given the same reference numerals.
[0027]
The hopper 1 for the general waste 9 loaded on the pallet 18 by the container lift 10 in which the lift cage device of the present embodiment is adopted as the lift cage of the container lift 10 of the sealed waste incineration facility as shown in FIG. 6, first, the pallet adapter 31 is first loaded into the space 16 of the lift cage body I from the front as in the case of the container 18 and placed as shown in FIG. Then, the engagement protrusion 19 of the lift cage body I is inserted into the rear end of the fork insertion hole 20a, and the clamp arm 22 of the clamp device 21 is rotated upward to place the tip of the fork insertion hole 20a. The lock pin 24 as the first lock mechanism and the nut member 29 of the second lock mechanism 26 are screwed onto the lock bolt 28 in a state of being inserted into the front end of the lock. By to lock the clamp arm 22, thereby the pallet adapter 31, as in the case of the container 17 described above, it is fixed to the lift cage body I. Next, the pallet 18 loaded with the general waste 9 is loaded onto the pallet adapter 31 from the front, and the rear end edge of the pallet 18 is engaged with the engaging portion 33 of the locking member 32 of the pallet adapter 31. Place to fit. Next, the small diameter portions 36 at both ends of the cross bar 35 are inserted into the cross bar insertion groove 34 from the front, and the cross bar 35 is arranged so as to overlap the front edge of the pallet 18 on the pallet adapter 31. After that, the turnbuckle mechanism 38 is operated to fix the position of the cross bar 35. Accordingly, the rear end edge of the pallet 18 is locked to the engaging portion 33 of the locking member 32 of the pallet adapter 31, so that the pallet 18 is held by the lift cage body I via the pallet adapter 31. Since the front edge is locked to the lower side of the cross bar 35, the lift cage body I is raised along the guide rail 11 of the container lift 10 as shown in FIG. When the cage is tilted rearward by the cage tilting mechanism, the pallet 18 is loaded on the pallet 18 while being prevented from dropping from the lift cage body I by being locked by the engaging portion 33 and the cross bar 35 of the locking member 32. Only the general waste 9 that has been used is put into the hopper 1. Therefore, the pallet 18 can be collected by returning the lift cage body I to the upright state.
[0028]
At this time, since the height dimension of the locking member 32 of the pallet adapter 31 and the height position of the crossbar insertion groove 34 are set in accordance with the thickest pallet 18, the thickness of the pallet 18 to be used is set. Even if the size changes, the rear edge of the pallet 18 is locked to the locking member 32 and the front edge of the pallet 18 is locked to the cross bar 35. Therefore, the pallet 18 is tilted when the lift cage body I is tilted. Never fall. When the planar dimension of the pallet 18 to be used changes, the rear end edge is made to abut against the locking member 32 so as to correspond to the position of the front end edge of the pallet 18 placed on the pallet adapter 31. Then, by adjusting the position of the cross bar 35 in the front-rear direction and fixing the cross bar 35 to the cross bar insertion groove 34, the front end edge of the pallet 18 whose rear end edge is locked to the locking member 32 is changed to the cross bar 35. Therefore, even if the pallet 18 has a different planar dimension, the general waste 9 can be collected after being put into the hopper 1.
[0029]
In addition, when carrying out the general waste 9 stored in the container 17 to the hopper 1 as shown in FIG. 6B, the pallet adapter 31 and the crossbar 35 are removed. Similar to the embodiment shown in FIGS. 1 to 3, the container 17 containing the general waste 9 is placed in the space 16 of the lift cage body I, and the fork insertion hole 20 of the container 17 is placed behind the container 17. The engaging protrusion 19 of the lift cage body I is inserted into the end portion, and the clamp arm 22 of the clamping device 21 is rotated upward to insert the tip portion into the front end portion of the fork insertion hole 20 to be locked. Then, the container 17 can be held without being dropped when tilted, and the container 17 can be collected.
[0030]
As described above, according to the present embodiment, when the general waste 9 loaded on the pallet 18 is transported, the pallet 18 can be collected. It can be reused.
[0031]
Furthermore, since the pallet adapter 31 includes the fork insertion hole 20a, the pallet adapter 31 can be stored in the space 16 of the lift cage body I and easily fixed by the engaging protrusion 19 and the clamping device 21. The crossbar 35 is inserted by inserting the small-diameter portions 36 formed at both ends into the left and right crossbar insertion grooves 34, and then contracting the entire length by a turnbuckle mechanism 38. Since it can be easily fixed in the groove 34, it is possible to easily cope with switching between the container 17 and the pallet 18.
[0032]
Further, the crossbar 35 attached to the crossbar insertion groove 34 has a stepped portion 37 formed at both ends thereof on the outside of the left and right side walls 14 of the lift cage body I that is outside the crossbar insertion groove 34. Since the position is fixed by applying a stress in the contraction direction while pressing against the side surface, it is possible to prevent the crossbar 35 from being inclined and disengaged between the left and right crossbar insertion grooves 34.
[0033]
Note that the present invention is not limited to the above-described embodiment, and the clamping device 21 has a clamping arm at the front end of the fork insertion holes 20 and 20a of the container 17 and the pallet adapter 31 placed in the space 16. As long as the front end portion of the container 17 and the pallet adapter 31 can be fixed by inserting the front end portion 22, the shape of the clamp arm 22 and the lock mechanism of the clamp arm 22 may be other than those shown in the drawings. 3 to 6 (a), the stepped portions 37 formed at both ends of the crossbar 35 are pressed against the outer surface of the lift cage body I that is outside the crossbar insertion groove 34. If the stress in the contraction direction can be generated in this way, the overall length of the crossbar 35 can be reduced by a configuration other than the turnbuckle mechanism 38, such as a screw mechanism. If the crossbar 35 can be fixed at any position in the front-rear direction of the left and right crossbar insertion grooves 34, the crossbar 35 can be individually inserted into each end. An arbitrary configuration such as a clamp mechanism for fixing to the groove 34 may be adopted, and the object to be conveyed is transported and thrown into the hopper 1 installed at a high place. The container lift 10 used in the above can be used in the lift cage of the container lift 10 of any equipment other than the sealed waste incineration equipment, and can be stored in the container 17 or loaded on the pallet 18 and transported. It is needless to say that the object to be transported is not limited to the general waste 9 and that various changes can be made without departing from the scope of the present invention.
[0034]
