Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transport apparatus, and more particularly to a novel improvement for easily transporting a heavy object to a predetermined position by rotating the object in a horizontal direction, a vertical direction, and a predetermined angle.
[0002]
[Prior art]
Conventionally, as a transfer device that has been conventionally used, a movable body that can be moved up and down by hydraulic pressure is generally provided on a base with a caster, an object is placed on the movable body, and the movable body is reached when it reaches a predetermined position. And the object was inserted into a predetermined storage location.
[0003]
[Problems to be solved by the invention]
Since the conventional transfer apparatus is configured as described above, the following problems exist. That is, since the conventional transport device has only the function of moving the object horizontally and up and down, it is extremely inconvenient to lift the aircraft slightly from the ground like a helicopter and store the object in the aircraft. It has been extremely dangerous to transport and store an object with a gap.
[0004]
The present invention has been made to solve the above-described problems. In particular, the object is easily transported to a predetermined position by rotating the object in a horizontal direction, a vertical direction, and a predetermined angle. It is an object of the present invention to provide a conveying apparatus configured to do so.
[0005]
[Means for Solving the Problems]
The conveying device according to the present invention includes a platform having casters and provided so as to be horizontally movable, a movable body provided on the platform so as to be movable up and down via a pair of bars crossing each other , and the movable body A pair of arms which are provided on one end side of the arm and spaced apart from each other, a holding body which is pivotally provided between the arms via a pivotal support and has an open top cup shape, and one of the arms. A rotation fixing knob provided on the rotation fixing knob; a shaft provided with the nut provided on the rotation fixing knob; an arc-shaped hole provided on a side of the holding body through which the shaft passes; and a plurality of springs provided in the holding body. The holding body is positioned ahead of the end portion of the base portion of the base portion, and the object in the holding body is elastically held by each elastic body .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a conveying apparatus according to the invention will be described with reference to the drawings.
In FIG. 1 and FIG. 2, a reference numeral 1 indicates a base portion having a caster 2 and configured to be movable in the horizontal direction. The base portion 1 has a known hydraulic drive unit (not shown). A movable body 5 provided on a pair of mutually intersecting bars 3 and 4 that are operated via each other can be raised and lowered. The drive unit operates the lifting lever 6 provided on the base unit 1 along the direction of arrow A, so that the moving body 5 rises, and the lowering lever 7 operates in the horizontal direction along arrow B. By doing so, the hydraulic pressure to the moving body 5 is reduced to zero and the original position can be lowered.
[0007]
One end 5a of the movable body 5 is provided with a pair of arms 8 and 9 which are separated from each other, and a cup-shaped holding body 11 is rotatable between the arms 8 and 9 via a shaft support portion 10. Is provided. One arm 9 of the arms 8 and 9 is provided with a rotation fixing knob 12, and the tip of the rotation fixing knob 12 is formed on a side portion of the holding body 11 and has an arcuate hole 13 having an arc shape over 90 degrees. And the shaft 12 a is engaged with the arcuate hole 13.
Accordingly, the holding body 11 is positioned ahead of the base end 1a of the base 1, and is configured to be able to rotate in the angular range (90 degrees) of the arcuate hole 13, as shown in FIG. 4 can be freely rotated in the horizontal direction shown in FIG. The holding body 11 is provided with four elastic bodies 20 made of springs, and is configured so that a heavy object 30 such as a heavy load can be elastically held in the holding body 11. Yes.
[0008]
Next, the operation will be described. First, in a state where the movable body 5 is lowered and joined to the pedestal 1, the object 30 is held in the holding body 11, and the holding body 11 is rotated in the horizontal direction ahead of the pedestal end 1 a. When the transport device 60 is inserted in the lower part of the front part of the helicopter 50 that is in a floating state in the raised state, the holding body 11 is raised from the horizontal direction to the vertical direction in correspondence with the opening 51a of the lower part 51 of the machine body. In this state, the object 30 and the opening 51a correspond to each other. In this state, after the rotation fixing knob 12 is turned and the object 30 is fixed, when the lifting lever 6 is operated, the moving body 5 is raised and the object 30 is moved. It is loaded into the opening 51a. The drive unit for moving the moving body 5 up and down is not limited to hydraulic pressure, and may be a known configuration using a motor and a feed screw.
[0009]
【The invention's effect】
Since the transport apparatus according to the present invention is configured as described above, the following effects can be obtained.
In other words, the holding body provided on the movable body that can move up and down can be rotated within a range of 90 degrees to change its posture between the horizontal position and the vertical position, so that even in a narrow position such as the lower position of the helicopter Can be conveyed to a predetermined position while holding the object, and the conveyance of the object in a narrow place can be greatly facilitated.
