Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to tunnel construction 1: a slag carrying facility for transporting raw slag out of the tunnel.

<Prior art> If the tunnel has a large cross-section, it is possible to transport pickpockets using a large stacker or dump truck, but in a tunnel with a small cross-section, it may not be possible to use these machines.

In order to cope with such a case, the unloading method shown in FIG. 7.8 has conventionally been adopted.

This transport method uses bucket a and sliding trolley b. First, load the sanding into bucket a on the face side, then hang bucket a from trolley hoist C and move it to just above the sliding trolley b. .

Next, as shown in Fig. 8, the stopper d attached to the bucket a is removed, the bucket a is overturned, and the shear is loaded into the shear opening.

After driving the loaded Suitoro B to the shaft,
The shear is being carried out of the mine.

<Problems to be Solved by the Present Invention> The conventional pickpocketing technique +tj described above has the following problems.

<B> The moment stopper d is removed, bucket a suddenly rotates.

Currently, the work of removing stopper d relies on the manual operation of workers, making it extremely dangerous to load items into Retro B rather than from Bucket A.

When loading suri to suritoro b, bucket a is suspended from beginning to end and is in an unstable state.

Therefore, the pickpockets fall off from the bucket a or are blown away from the rapidly rotating bucket a, causing a loss in the loading of the pickpockets.

<C> After operating the trolley hoist C on the floor of the mine, the worker climbs up to the sliding trolley B to overturn and return bucket A, so it is difficult to climb up and down to the sliding trolley B. Not only is it time consuming, but it is also difficult to work with.

<Object of the present invention> The present invention was made to solve the above problems, and its purpose is to ensure the safety of workers and to suppress spillage of shear from the bucket. To provide a pickpocket transport facility that can efficiently load pickpockets.

<Means for Solving the Problems> The present invention provides a transporting machine that includes a bucket for storing shear that is horizontally movable and vertically suspended, and a cargo box for loading the shear in the bucket. In the shear transport facility, the bucket is rotatably provided with both ends of a portal-shaped hanging arm on the upper part of the bucket, and a pair of overhanging rods are provided on the lower part of a pair of opposing sides of the bucket, The transporter is provided with a pair of support arms protruding upward from the upper edges of the side surfaces on a pair of opposite sides of the loading box, and a mooring portion with an overhang rod is formed at the upper end of the support arm, The present invention relates to a shear transport facility characterized in that a bucket is configured to be rotatable around a mooring point between an overhang rod and a support arm as a fulcrum.

Description of the present invention> The present invention will be described below with reference to the drawings.

<A> Pickpocket transport facility FIG. 1 shows a shear transport facility according to the present invention.

The pickpocket carrying device includes a rotating bucket 10 and a pickpocket transporter 20.
Consists of.

The rotating bucket 10 is a box that transports shear generated at the face to the shear transporter 20, and is suspended from a known trolley hoist or the like so that it can move up and down inside the mine and can move laterally.

The pickpocket transporter 20 carries the carts loaded by the rotating bucket 10 inside the mine, and is composed of a cargo box 21 having a traveling function.

<mouth> rotating bucket FIG. 2 shows the rotating bucket 10 with a part broken.

The rotating bucket 10 has a bucket main body 11 with an open top, and a support shaft 12 on a pair of opposing sides of the bucket main body 11.
．． A gate-shaped hanging arm 13 rotatably supported at 12;
A pair of overhanging rods 14 protruding from the sides of the bucket body 1■.
14 and more.

The bucket body 11 is formed of an iron plate or the like with an open top, and has a plurality of sets of running wheels 15 on the bottom surface thereof.

Figure 3 shows a support shaft 12 attached to the side of the bucket body 11.
and the attachment of the overhang rod 14 indicate the position.

Each support shaft 12.12 is mounted at the upper center of the side surface in consideration of the stability 11 of the bucket body 11.

Each extension rod 14.14 is on a perpendicular line passing through each support shaft 12.12, and protrudes from the lower side surface of each support shaft 12.12.

Further, FIG. 4 shows an example of a mechanism for restraining the swinging of the rotating bucket 10 when the rotating bucket 10 is suspended.

A U-shaped stopper 16 is rotatably attached to the upper side of a bucket body 11 provided with a support shaft 12, and a protrusion 17 for preventing the stopper 16 from lowering too much is provided on the side slightly lower than the stopper 16.

With this configuration, when moving the rotating bucket 10, the opening of the stopper 16 can be made to straddle the hanging arm 13 to restrain the swinging of the bucket body 11.

Also, when you want to rotate the bucket body 11, use the stopper 16.
Just roll it upwards.

In addition, 18 in FIG. 4 is an auxiliary hook for hanging with a hoisting winch.

<C> Pickpocket transport machine The pickpocket transport machine 20 may be either a rail type that runs on rails 30 or a type that runs on its own using tires. Can be adopted.

The shear carrier 20 has a function of discharging shear from the cargo box 21.

The pickpocket ejecting means may be a wide-opening type, a side-opening type, or an overturning type for the cargo box 21.

A pair of support arms 22 are arranged vertically on a pair of opposing sides of the cargo box 21 of these known pickpockets 20.
．． The lower part of 22 is fixedly provided.

A receiving groove 23 is cut out in the upper part of the support arm 22 in a U shape.
form.

The opening width of the receiving groove 23 is set to a size that can accommodate the extending rod 14 of the rotating bucket 10.

Further, the total length of the support arm 22 is made long enough to support the rotating bucket 10 and allow it to fall.

Next, the method for transporting the shear will be explained.

<A> Movement of the rotating bucket As shown in FIG.

While the rotating bucket 10 is moving, the stopper 16 is placed astride the hanging arm 13.

Next, as shown in FIG. 5, the rotating bucket 10 is lowered using the trolley hoist 40 until the extending rod 14 is accommodated in the receiving groove 23.

When the overhanging rod ■4 is accommodated in the receiving groove 23, the stopper 16
Remove.

At this time, the total weight of the rotating bucket 10 is transferred to the pickpocket transporter 20 and the trolley hoist 4 via the extending rod 14 and the support arm 22.
Supported by 0.

Therefore, even if the stopper 16 is removed, the rotating bucket 10 is suspended so that it will not fall over, so the rotating bucket 10 will not suddenly rotate as in the conventional case.

Then, when the trolley hoist 40 continues to be lowered, the rotating bucket 10 slowly rotates about the mooring point of the extending rod 14 and the support arm 22 as a fulcrum.

As a result, the shear in the rotating bucket 10 is reduced by the shear transporter 20.
The shear loading process is completed.

When the shear loading work is completed, the rotating bucket 10 is lifted and moved to the face.

When the pickpocket transporter 20 is full of pickpockets, the pickpocket transporter 2
Move 0 to the shaft.

As shown in FIG. 6, if the extension rod 14 is installed away from the perpendicular line passing through the support shaft 12, the rotating bucket 10
The direction of rotation can be regulated.

<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.

<B> By simply operating the hoist from a position away from the rotating bucket, the worker can remove the shear from the rotating bucket to the shear carrier.

Therefore, the safety of workers can be ensured.

<Exposure> Workability is good because the hoist can be operated to load the shear.

<C> Since the bucket can rotate slowly using the lower part of the bucket as a fulcrum, there is less spillage of the pickle and loading loss can be reduced.
