FIG. 1 is an overall view of a suspended conveyance device according to the present invention, FIG. 2 is a left side view of FIG. 1, and FIG. 3 is a plan view of FIG.

As shown in FIG. 1, the suspended transfer apparatus 10 for an object to be transferred can be moved and moved along a track 16 whose truck 12 is laid in a tunnel 14 having an empty head height of 3.9 m, for example. , And are installed at desired positions by jacks 20, 20 ... Attached to both sides of the wheels 18, 18 ,. On the dolly 12, a rack 2 provided in an operation panel 22 and a frame 23 in order from the left in the drawing.
4. The hydraulic unit 26 is mounted. In the rack 24, a plurality of dug pipes 28, 28, ... Shown by a chain double-dashed line in the drawing are arranged and stored in the vertical direction. These dug pipes 2
.. are arranged in four rows in the length direction of the carriage 12 and three rows in the width direction, and 12 pieces are stored in one rack 24. Stabilizer rod 2 on the other front end
7 etc. are also stored. Further, the drill pipes 28, 28 ...
Are placed on a plurality of rollers 29, 29 ... Arranged along the length direction of the carriage 12, and these rollers 29,
It is stored so as to be slidable in the width direction of the carriage 12 by the rotation of 29.

On the upper surface of the frame 23, a pipe conveying means 30 for transferring and collecting the pipe is provided. The digging pipe transporting means 30 includes a slide boom 34 having a winch 32, and jacks 36 and 38 for sliding the slide boom 34 in the lengthwise direction of the suspending and transporting device 10. The slide boom 34 has a first boom 40 slidably supported on the upper surface of the frame 23, and a second boom 42 slidably supported on the first boom 40. The winch 32 is installed substantially in the center of the second boom 42.

On both sides of the first boom 40, as shown in FIGS. 2 and 3, the jack 3 fixed to the frame 23 is provided.
6, 36 rods 44, 44 are connected, and jacks 38, 38 are mounted. This jack 38,
The rods 46, 46 of 38 are connected to both sides of the second boom 42. Rod 4 of each jack 36, 38
When 4 and 46 are extended and retracted, the first and second booms 4 and 4
By the relative sliding movement of 0 and 42, the pipe conveying means 30 slides within the range of the stroke L shown in FIG. 1, whereby the sheave 33 of the winch 32 is moved from the position where the pipe 28 is replenished. The slide pipe 28 is slid within the range of the last row position of the drill pipe 28 stored in the rack 24.

A drill pipe connecting jig 50 is attached to the tip of the drill pipe suspending wire 48 connected to the winch 32 via the sheave 33. This jig 50
Has a structure attachable to and detachable from the upper end of the digging pipe 28.
The sheave 33 is supported so as to be slidable in the width direction of the second boom 42 by the operation of a silling that can move the sheave 33.

Next, the operation of the suspending and conveying apparatus configured as described above will be described. First, the trolley | bogie 12 is utilized, the suspension conveyance apparatus 10 is made to run along the track 16, and it moves to the excavation position of the hole 52. Next, the digging pipe conveying means 30 of the suspended conveying device 10 is operated to move the sheave 33 to the first row of the digging pipes 28, 28 ... (One row from left to right in the drawing) stored in the rack 24. The first jig 50 of the wire 48 is connected to the drill pipe 28 at the center of the first row.

Next, the digging pipe conveying means 30 is operated to move the sheave 33 above the digging position. And wire 4
8 is rewound and the drill pipe 28 is suspended toward the drill pipe 28A in the hole. At this time, when the centering position (boring center) of the digging pipe 28 with respect to the digging pipe 28A is misaligned, the jacks 36 and 38 are operated to operate the sheave 3
Move 3 Or attached to the second boom 42
Actuating the cylinder 35 to move the sheave 33 to the second boom 4
The slide pipe 28 is slid in the width direction of 2 (left-right direction).
To the bowling center. That is, in this embodiment, since the drill pipe 28 can be moved in all directions by driving the jacks 36 and 38 and moving the sheave 33,
The drill pipes can be easily centered and added together. The digging pipe 28A is also carried and replenished by the suspending and carrying device 10.

Next, the jig 50 is removed from the digging pipe 28, the second boom 42 is evacuated, and then the digging pipe 2 is replenished.
A swivel head of a drilling pipe device (not shown) is connected to the upper end of 8, and the length of the drill pipe 28 is excavated by this swivel head. When the excavation work by the first drill pipe 28 is completed,
As described above, the second pipe 28 in the first row is taken out from the rack 24 by the pipe conveying means 30. Then, the digging pipe 28 is transferred above the first digging pipe 28 and added to the first digging pipe 28. In this case, the second drill pipe 28 is
Before being transferred, it may be moved to a position where the first drill pipe 28 is stored, that is, directly below the sheave 33.

Thus, in this embodiment, the drill pipes 28, 2 are
8 ... are stored in the rack 24 and transported to the excavation position, and the excavation pipe 28 is transferred to the excavation pipe addition position by the excavation pipe conveying means 30, so that the excavation pipe transfer work and the addition work are performed. It can be done efficiently. Also,
In this embodiment, the pipes 28, 28 ...
The winch 32 removes a predetermined length from the hole 52,
Then, after separating them one by one, they can be transferred into the rack 24 by the digging pipe conveying means 30 and collected.

FIG. 4 is an explanatory view showing an embodiment in which the suspending and conveying apparatus according to the present invention is applied to convey a core material, particularly H steel, which is the same as the embodiment shown in FIGS. 1 to 3, or Similar members are designated by the same reference numerals, and description thereof will be omitted. The H steel 60 is stored in the rack 24 on the crawler 62, and is lifted by the digging pipe conveying means 30 installed on the upper portion of the frame 23. And H steel 60 is
After being transferred to the position of the hole 52, it is added to the H steel 60A inserted in the hole 52. Also, H steel 60 has holes 5
Since it is buried in 2, this transfer device has a predetermined number of H
After burying the steels 60, 60 ..., a new H steel is mounted without recovering the H steel 60 and the H steel 60 is moved to the next H steel burying position.

A jack (not shown) is provided at the front of the crawler 62, and the crawler 62 is utilized by using this jack.
H steel 6 by lifting and supporting the front part of
It is possible to prevent the trailing accident of the crawler 62 when 0 becomes empty. In this embodiment, the suspended transfer device applied to a narrow place or a tunnel with a height restriction was described, but the present invention is not limited to this, and it can be used in a place other than such a restricted place. You can

Further, in the present embodiment, the example in which the jack mechanism is used as the conveying means has been described, but the present invention is not limited to this, and the conveying means may be constituted by a crane mechanism.

[0021]

As described above, according to the suspending and conveying apparatus of the present invention, a carriage having a moving device such as wheels or crawlers is used to move to a work place and then stored in a rack. The transferred object is transferred by the transfer means 1
Since the books are transferred to a predetermined position one by one, it is possible to efficiently perform the work of transferring the objects to be conveyed and the work of adding the objects.

Further, in the present invention, the first and second transfer means are provided.
Drive the jacks to slide the first and second booms on the upper part of the rack, position the wire of the winch at a position corresponding to the long heavy object to be transferred, and connect it to the object to be conveyed, and , 1st, 2nd by 1st, 2nd jack
Since the boom is slid to convey the conveyed object to a predetermined position, the conveyed object can be conveyed with a simple structure and connected to be built in a deep hole.

Further, according to the present invention, since the position of the wire can be finely adjusted in all directions by the movement of the first and second booms and the movement of the sheave, the centering adjustment of the transported object is facilitated. It can be carried out.
