Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a monorail type cargo handling device used for carrying materials and other construction equipment in a tunnel during tunnel construction work and the like.

In particular, the present invention was devised for the purpose of providing a highly functional and safe underground cargo handling apparatus in which the rail movement in this cargo handling apparatus is constituted by a motor drive system.

(Prior art) In order to handle construction materials and other equipment in the mine during tunnel construction work, a single track rail is hung from the ceiling in the mine, and a cargo handling device such as a hoist is freely mounted on this single track rail. Also, a so-called monorail type cargo handling device is well known.

Compared to other cargo handling equipment such as gate cranes, this monorail-type cargo handling equipment is superior in terms of functionality, safety, and economy as a cargo handling equipment in a restricted place such as a tunnel mine. It is that you are.

(Problems to be solved by the invention) By the way, in this monorail type cargo handling device, when tunnel construction work progresses and the range of cargo handling work inside the mine is extended, the cargo handling device naturally changes its working range. Must correspond to. Therefore, conventionally, depending on the extension of the working range, a new rail is added to the face of the face, or an existing rail is moved to the face of the face. However, the method of adding new rails results in installing rails over the entire extension line of the tunnel construction, which is extremely uneconomical considering that the use range of the cargo handling device is mainly limited to the face side. .

Therefore, generally, a so-called rail moving method is used in which the existing rail is moved to the face of the face as the construction progresses.

And as the means for moving the rail, the methods currently used include a simple method of manually moving the rail, a method of supporting the rail with a rubber roller, and rolling using the friction of the rubber roller. In addition, a method of moving the wire rope by connecting it to the rail and pulling the wire rope is used.

However, the manual method by man has a problem in safety and work efficiency required for movement, and is particularly unsuitable because it is dangerous when the place to move is an inclined ground such as an inclined shaft.

Also, the rubber roller is easier to move the rail itself than the manual method, but the rail is generally heavy and does not move smoothly, or if the place is an inclined shaft,
On the contrary, there is a risk that the rail will slip down.

Furthermore, the method of connecting the wire rope to the rail and moving the wire rope by pulling the wire rope has a drawback that the wire hanging is troublesome and the work becomes difficult when the wire rope is loose.

In any case, since the conventional rail moving method has drawbacks in workability, efficiency, and safety, it has been demanded to realize a further improved rail moving type underground unloading apparatus.

In order to meet such demands, the present invention has devised a rail-moving monorail that can move rails safely, easily, and efficiently, and has functionality, safety, and economy as an underground unloading device. The aim is to improve the sex.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the feature of the means adopted by the present invention is that the upper and lower surfaces of the upper and lower flanges of a rail material having an I-shaped cross section are respectively mounted on the rack. A rail with a rack, a pair of guide rollers for supporting the left and right lower surfaces of the upper flange of the rail with the rack, and a rail moving device with a drive motor having a pinion that meshes with the rack on the upper surface; Equipped with a pair of guide rollers that support the left and right upper surfaces of the lower flange of the rail
In addition, a rail moving type monorail by a motor drive system is configured by combining with a hoist traveling device having a pinion that meshes with the rack on the lower surface.

That is, the rail is configured as a rail having a rack, the pinion is meshed with the rail, and the drive motor is used to rotate the pinion so that the rail can be moved using an electric motor.

The rack of the rail with rack is not a so-called gear type rack, but roller chains may be provided by extending on the upper and lower surfaces of the rail material. Of course, in this case the pinion is constructed with sprockets.

(Operation) As described above, according to the present invention, the rails with racks provided with racks on the upper and lower sides of the rails and the rails with the racks are supported by the guide rollers of the rail moving device with the drive motor. Since the pinion is meshed with the rack, when the drive motor is operated, the rack rail can be moved back and forth as the drive motor rotates. Also, the hoist traveling device supported on the lower flange of the rail with rack has the pinion meshed with the pinion provided on the lower surface of the lower flange. It is free to travel along.

Therefore, when the tunnel excavation progresses and the cargo handling work position is moved to the cutting face side, the rail itself can be automatically moved to the cutting face side by operating the drive motor of the rail moving device with a drive motor. . Further, this point will be specifically described based on Examples.

(Example) As described above, the rail-moving monorail according to the present invention includes a rail with a rack, a rail moving device having a drive motor for supporting the rail with the rack, and a lower flange of the rail with the rack.

A rail moving device with a drive motor equipped with a motor, and C is a hoist traveling device.

As shown in FIG. 2, the rail A with rack is made of a so-called rail material 1 having an I-shaped cross section, and has a unit length of about 30 m.

In the embodiment, the flanges 1a and 1a of the rail material 1 are used.
Instead of a rack, roller chains 2a and 2b are fixedly installed over the entire length on the upper surface and the lower surface of b, respectively. 3a and 3b are mounting rails fixed to the rail material 1 for mounting the roller chains 2a and 2b.

Next, as shown in FIG. 2, a rail moving device B with a drive motor for supporting the rails with racks is provided on the lower side of the upper flange 1a of the rails A with racks at the bottom of the frame 4 having an inverted U shape. A guide motor 5a, 5b for supporting the roller is pivotally supported, and a drive motor 7 having a sprocket 6 meshing with the rack of the rail A with a rack, that is, the roller chain 2a is attached to the side surface.

That is, when the drive motor 7 is rotated, the sprocket 6 is rotated and the rail A with a rack is moved in the front-rear direction according to the rotation direction of the sprocket 6.

As shown in FIG. 1, the rail moving device B with a drive motor is suspended from the ceiling of the tunnel with a constant span to support the rail A with a rack. That is, it is suspended in three places over a total length of about 30 m.

Reference numeral 11 denotes a mounting seat for mounting the upper end of the suspension rod 8 on the ceiling side of the tunnel. In the embodiment, as shown in FIG. 4, it is fixed to the support 12 used for tunnel construction with bolts or the like. is there.

Further, a plurality of intermediate suspensions 14 having receiving rollers 13 are provided between the rail moving devices B with drive motors suspended from the ceiling of the tunnel, as shown in FIG. To support. Furthermore, both ends of the rail A with a rack are fixed to the ceiling side by brace members 15 that rock the turnbuckle.

Next, as shown in FIG. 3, the hoist traveling device C is mainly composed of a U-shaped frame 16 symmetrically with the frame 4 of the rail moving device B with a drive motor.
Is provided with a pair of guide rollers 17a and 17b supported on the left and right upper surfaces of the lower flange 1b of the rail A with rack, and the rack of the rail A with rack, that is, a roller chain, is provided on the side surface of the frame 16. A drive motor 19 having a sprocket 18 that meshes with 2b is attached.

That is, when the drive motor 19 is rotated, the hoist traveling device C can relatively move along the rail A with a rack.

The rail-moving monorail according to the present invention, as described in the above embodiment, suspends the rail moving device B with the drive motor at a constant distance from the ceiling of the tunnel, and suspends the rail moving device with the drive motor. B. A rail A with a rack is supported between B, and a hoist moving device C is further movably supported on a lower flange 1b of the rail A with a rack thus supported, and a hoist is attached to this. Compared with the conventional monorail type cargo handling device, there are the following functional differences.

(1) The rail itself is configured as a rail with a rack, and this rail with a rack is supported by a rail moving device with a drive motor. Therefore, the rail with a rack can be automatically moved by operating the drive motor. You can

That is, if the excavation of the tunnel progresses and the cutting face position moves, a rail moving device with a drive motor is suspended and added to the ceiling in the mine face side mine accordingly, and a suspension is installed in the middle, and the rear position is set. By rotating the drive motor of the drive motor-equipped rail moving device, the rack-equipped rail is transferred to the added drive motor-equipped rail moving device via the intermediate suspension, and is automatically moved to the face side.

Therefore, compared with the conventional manual method and a moving method such as a pulling method using a wire rope, the method is efficient and safe, and the work is completed in a short time, which has a favorable influence on the construction period of the entire tunnel construction. (2) It is not necessary to add a new rail, and a rail moving device with a drive motor,
Since it is possible to continue functioning as an underground unloading device simply by providing intermediate suspensions in sequence, it is extremely economical as well as functional, and it is possible to reduce the cost of heavy equipment required for construction.

(3) Especially, since the rail is a rail with a rack, and the pinion is engaged with this rail to move,
The movement is extremely safe and can exert an effect not seen in the conventional monorail type cargo handling device.

As a matter of course, even if the rack of rails with racks is replaced with a roller chain as shown in the embodiment and the sprocket is engaged, the same operational effect is expected.
