Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a mechanism for distributing necessary materials or equipment such as segments to a plurality of cranes running in parallel even in a small space.

[0002]

2. Description of the Related Art When constructing a tunnel by the shield method, it is necessary to drop necessary materials or equipment (hereinafter, referred to as materials) such as segments covering the inner wall of the tunnel after excavation from the ground surface into the tunnel. Since the material unloading place is fixed for each section, the material unloaded in the tunnel is transported to a truck by, for example, a crane, and further transported to the assembly site by the truck. At this time, for example, if the cross section of the tunnel is large, such as a subway station,
After being lowered into the tunnel, it is distributed to a plurality of traveling cranes by a forklift or the like.

[0003]

When constructing a subway station in an urban area, there are cases where it is necessary to set a material drop-off place to a place other than the station due to restrictions on the surrounding environment. In this case, the materials must be distributed in the tunnel section having a small cross section, but in some cases a forklift cannot be used due to space restrictions. In addition, simply arranging the electric traverser causes the cable of the electric traverser to cross the rail of the crane, and the cable is likely to be disconnected by the wheel of the crane, which is not practical.

Accordingly, the present invention is to provide a practical method and a mechanism for distributing to a practical parallel traveling crane using an electric traverser capable of distributing and transporting a transported object to a plurality of parallel traveling cranes even in a narrow space. Aim.

[0005]

According to a first aspect of the present invention, there is provided a rail for an electric traverser so as to intersect a rail for a plurality of cranes. (3) is laid, and at the portions where the rails for the crane and the rails for the electric traverser intersect each other (for example, at the intersection 5), portions of both rails corresponding to both sides of the other rail are respectively depressed. The crane rails (12 or 22) can be moved to move, and one of the recesses (for example, the cable recess 4b) provided on the crane rail is inserted with the power supply cable (for example, the cable 14) of the electric traverser (1). And the electric traverser loaded with the conveyed object is dropped into the deepened recess while the power supply cable extending from the electric traverser is dropped into the electric traverser. By moving the crane rail along the rail for crane to the rail for crane and moving the crane (2) traveling on the rail for crane onto the electric traverser, the crane (2) is installed on each of the plurality of crane rails. And distributing the article to one of the cranes.

[0006] Unlike a forklift, an electric traverser requires a small space for installation. In addition, the electric traverser is less expensive than the battery type electric traverser, there is no possibility of interruption of the operation due to running out of the battery, and the handling becomes easy because there is no need for charging. Further, since the power supply cable of the electric traverser is dropped into the recess provided in the rail, there is no possibility that the wheel of the crane will crush the power supply cable and break it. Therefore, it is possible to provide a practical method for sorting conveyed materials such as materials to a plurality of traveling cranes in a smaller space, and for allocating the materials to the traveling cranes in a practical manner.

According to the present invention, at least one of a crane and an electric traverser includes:
A plurality of drive wheels may be provided at different positions on the same rail, and even if one drive wheel fits into the recess of the rail, another drive wheel is driven on the rail to move the electric traverser. Good. In this case, the electric traverser moves stably without stopping even if one of the drive wheels is fitted into the concave portion on the rail, so that the transported object can be more reliably distributed to the crane.

According to a second aspect of the present invention, a rail (3) for an electric traverser intersecting with a rail (4) for a plurality of cranes and a wheel (12 or 22) of each other are provided. In order to enable travel, the rails for the electric traverser and the rails for the crane intersect each other (for example, at the intersection 5), and are provided at portions corresponding to both sides of the opposite rail of both rails. One of the recesses (3a, 4a, and 4b), the electric traverser (1) running on the rail for the electric traverser, and the recess provided on the rail for the crane, and a power supply cable for the electric traverser. A cable recess (4b) that is deepened so as to enter therein, and a power supply cable (for example, cable 14) that extends from the electric traverser as the electric traverser moves. And wherein the electric traverser for rail, a sorting mechanism for running alongside the crane provided with said guiding means for guiding the sides provided with recesses for cables (for example, the pulley 16), during stretching.

According to the second invention, a mechanism for performing the first invention can be provided. Here, as described in claim 4, if at least one of the crane and the electric traverser is configured to have a plurality of drive wheels at different positions on the same rail, a mechanism for performing the method according to claim 2 is provided. .

As shown in FIGS. 1 and 2, the present mechanism comprises two cranes 2 running in parallel along two sets of rails 4 and 4 (crane rails) inside a tunnel 7 under construction. Rails 3 intersecting both sides of the set of rails 4,
3 (rails for the electric traverser) using the electric traverser 1 and using the crane 100 installed on the ground, the material 6 enters the inside of the tunnel 7 being constructed from the opening 110 through the opening 6 (see FIG. 5). (Only shown), and is directly placed on the electric traverser 1 at the origin by the crane 100, and these materials 6.
, The materials 6 are transferred from the cranes 2 to a bogie (not shown) and transported to the assembly site on the left side in the figure. In this case, as shown in FIG.
The area immediately below 0 corresponds to a normal tunnel section, and the assembly site corresponds to a subway station.

The electric traverser 1, as shown in FIG.

A pair of wheels 12, 12 are fixed to four corners of the lower surface of the pair 1, respectively, so as to be mounted on the rail 3.
A motor 13 for simultaneously driving the gantry 12 is mounted on the lower surface of the gantry 11 for each rail 3.
A cable reel 15 for winding and holding a cable 14 including a power supply cable to the motor 13 and a signal cable is provided at one corner of the upper surface of the motor 1.

That is, two pairs of wheels 12 are mounted on each rail 3, one of which serves as a driving wheel and the other pair serves as a driven wheel. Here, the wheels 12, 12 serving as drive wheels, are provided with gears 12 a concentrically inside, and these gears 12 a, 12 a are both meshed with a gear 13 a attached to the drive shaft of the motor 13. . In addition, the interval between these paired wheels 12, 12 is
It is wider than between the concave portions 3a, 3a, which will be described in detail later.

The cable reel 15 is disposed immediately above the pair of wheels 12, 12 and in parallel with the wheels 12, and rotates with the movement of the electric traverser 1.
After extending from the cable reel 15, the cable 14 is disposed in front of and directly beside the wheel 12, and passes through a pulley 16 (guide means) passing just above a cable recess 4 b (details will be described later). Or into the cable recess 4b.

The crane 2 is, as schematically shown in FIG.
An outline is a well-known club-type bridge crane. A pair of wheels 22, 22 are fixed to four corners of a lower surface of a gantry 21 for holding a main part of the crane on an upper side, respectively, in a direction to be mounted on rails 4, A motor 23 for simultaneously driving the wheels 22 and 22 is mounted on the upper surface of the gantry 21, one for each rail 4, and a cable 24 including a power supply cable and a signal cable is provided at one corner of the upper surface of the gantry 21. This is a configuration in which a cable reel 25 for winding and holding is provided.

Further, as shown in each of FIGS.
Is interrupted so as not to overlap with the rail 4 at an intersection 5 (intersecting portion) where the rail 4 intersects, and recesses 3 a are formed on both sides of the rail 4. Further, the rail 4 has a recess 4a formed by recessing one of the portions corresponding to both sides of the rail 3 at the intersection 5 and forming a recess 4b for the cable by interrupting the other. These recesses 3a, 4a
Or the wheel 22 is passed through, respectively, and the cable recess 4b is
... and drop the cable 12 extended as described above.

In the sorting mechanism for the parallel traveling crane having such a configuration, the electric traverser 1 having the materials 6...
While dropping it right next to and into the cable recess 4b,
It moves along one of the rails 3 and 3 between the rails 4 and 4.

At this time, two driving wheels 12 are provided for each rail 3, and the interval between them is wider than that between the recesses 3a.
, The electric traverser 1 moves without causing the wheels 12... To run idle.

Then, the crane 2 on the rails 4, 4
Moves over the electric traverser 1. At this time, the cable 12
Is dropped into the cable recess 4b at the portion intersecting with the rail 4, so there is no possibility that the wire will break when the wheel 22 of the crane 2 passes. The crane 2 moves without causing the wheels 22 to idle for the same reason as the electric traverser 1.

Then, the crane 2 lifts the materials 6 placed on the electric traverser 1 and transports them to the bogie. At this time, since the cable 22 is dropped into the concave portion 3a,
Even if the electric traverser 1 returns to the origin later, there is no possibility that the electric traverser 1 will be disconnected by the wheels 12.

Therefore, according to the present mechanism, even in a narrow tunnel 7 where a forklift cannot be used, the segments can be distributed to the cranes 2 that run in parallel at low cost and efficiently using the electric traverser.

It should be noted that the present invention is not limited to only the configuration of the above embodiment, but can be arbitrarily modified without departing from the spirit of the invention.
