[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a power feeding type tire traveling crane device.

[0002]

BACKGROUND ART For example, a container crane of the tire running type which is used to send off the trailer container dumps stage and stacked containers to ground yard, or conversely the container to trailer, the front of FIG. 6 As shown in the figure, a power generating engine 2 is provided below one pillar of a gate-shaped body frame 1 and a power supply unit 3 is provided below the other pillar.
The power generated by the engine 2 is used as power for driving the entire crane, including traveling of the crane, traversing of the trolley 4, raising and lowering of the hoisting machine 5, control of the spreader 6, steering of the traveling tire 7, and the like. I have.

[0003]

The tire traveling crane of this type does not require a traveling rail and an external power source, and can use a self-built power generator to cover all required power. Therefore, the traveling lane can be easily changed. Although there are advantages such as being able to do so, in a collection site such as a container yard, since many tire traveling container cranes operate continuously, noise and exhaust gas generated by the crane's power generation engine reduce noise and air pollution problems. May also wake up. In addition, a luggage transporting device using a trolley car that travels while receiving power supply from a power supply trolley wire suspended from the ceiling of a structure as described in Japanese Patent Application Laid-Open No. 51-50186 has been proposed. . However, since this device has a configuration in which the current collector and the trolley car are connected separately with an electric wire, the trolley car and the current collector are controlled in synchronization while the tension of the electric wire is maintained during traveling of the trolley car. In addition to requiring equipment,
When the trolley vehicle is stopped, there is an inconvenience that the trolley vehicle has to be positioned directly below the current collector in order to maintain the tension of the electric wires.

[0004] The present invention has been proposed in view of these circumstances to eliminate or reduce the problem of noise and exhaust, yet provides efficient possible use is powered tire traveling crane device container yard The purpose is to do.

[0005]

SUMMARY OF THE INVENTION The present invention provides a tire traveling crane having a portal crane body.
Powered tie configured to move along a plurality of rows of crane tracks parallel to each other by running tires attached to the lower ends of both legs of a crane body of the type.
A traveling crane device formed between adjacent ones of the plurality of crane traveling paths.
With the extension building feeding trolley wire is bridged by a plurality of struts that are established at appropriate intervals along the path, and a current collector for collector power requirements in contact with the feeding trolley wire, the current The electrical equipment is connected to the clay
Current collector mounted on another crane body on the road
Sharing the trolley wire and support column that feeds into contact
Collects required power by contacting the installed power supply trolley wire
As can be, characterized in that attached to the current collecting frame which projects upwardly from the corner section of the upper digit of the passage side of the gantry crane body.

[0006]

According to such a configuration, required power can be obtained from a trolley line which is stretched at an appropriate height along the traveling lane and supplied with an external power supply through a current collector. Therefore, since the tire crane itself does not usually have a built-in engine and electricity, no noise and no exhaust are generated. Moreover, since the tire is a tire traveling crane, the traveling lane can travel without the need for rails, power supply pits and trolley wires, and the traveling lane can be easily changed. Current collector
Current collecting frame of order mounting a is provided so as to project upward from the corner portion of the portal crane body. Therefore, the columns supporting the trolley need only be established at appropriate intervals along the passages every other row of the plurality of passages (the passages are formed between a number of container accumulation sections) in the container yard. As a result, in the passage where the pillars are not established, since the passage of the trailer is not hindered even if the passage width is reduced, the width of the container accumulation section can be increased accordingly . The efficient use of the container yard becomes possible.

[0007]

FIG. 1 is a front view, FIG. 2 is a side view taken along the line II-II of FIG. 1, FIG. 3 is a plan view of FIG. 1, and FIG. 1 and 2 are side views of the current collector, and FIG. 5 is a front view of FIG.

The main difference between the present invention and the tire traveling crane shown in FIG. 6 is that the built-in power generator is abolished, and the required electric power is supplied from a trolley wire of an appropriate height installed along the traveling lane. The point is that they have been taken in after passing through.

First, in FIGS. 1 and 2, the same reference numerals as those in FIG. 6 denote the same members as those in FIG. 6, and reference numeral 10 denotes a current collector projecting upward from one corner of the upper girder of the crane body 1. 1 shows a mounting base, on which a current collector 11 is provided. A plurality of pillars 13 are erected at appropriate intervals at positions corresponding to the movement line of the current collector 11, that is, the locus, and trolley wires 12, 12 are erected using the pillars 13 as a support. Here, as shown in FIGS. 4 and 5, the current collector 11 is configured by providing two sets of current collectors 11 and 11 in parallel to correspond to the two trolley wires 12 and 12 of the DC power supply. Have been.

Next, FIG. 3 is a plan view showing an example of the arrangement of the crane in the container yard. In FIG. 3, reference numeral 15 denotes a container accumulation section laid out in parallel with a passage 16 interposed therebetween. The crane body 1 is disposed across a row of container stacking sections 15 and travels in an automatic steering direction in the longitudinal direction of the container stacking section 15 using a guide signal line or the like on a road (not shown) as a guide, and is driven by a trailer 18 (see FIG. 1). The container 17 conveyed into the container stacking section 15 is configured to be lifted by the spreader 6 and stacked in the container stacking section 15, or vice versa. Here, in this embodiment, Ru attached current collectors 11
The current collecting frame 10 for, are arranged so as to project upward from the corner portion of the crane body 1 of the portal. Therefore,
As shown in FIG. 3, a plurality of passages 16 in the container yard are supported by the pillars 13 supporting the trolley wires 12, 12.
In other words, it is only necessary to set up the passages 16 at appropriate intervals in every other row (the passages 16 are formed between the multiple container accumulation sections 15). As a result, in a passage in which the columns 13 are not established, even if the passage width is reduced, the passage of the trailer 18 is not hindered. Therefore, the width of the container accumulation section 15 can be increased correspondingly, and the container yard can be efficiently used. Use is possible. In addition, two trolley wires 1
2 and 12 are supported symmetrically along the longitudinal direction of the passage 16 on both sides of the column 13 and at positions on the movement line of the current collector 11 of the crane body 1.

[0011] Now, when a crane 1 in the same manner as the second passage perpendicular to one end of the passageway 16 of the integrated compartment 15 (the vertical direction of the passage of FIG. 3) to allow the feeding traveling,
In FIG. 3, a second trolley wire is provided on a right-angled passage at one end of the traveling lane at a slightly lower level not in contact with the trolley wire 12 on the passage 16, and the crane body 1 is provided with the second trolley wire from the second trolley wire. A second base and a second base for collecting electricity
May be additionally provided. Crane body 1
Is to receive power via the current collector 11 from Toro <br/> Lee line 12 traveling in the longitudinal direction of the container integrated compartments 15 performs integrated transfer operation of the containers 17, also perpendicular one end of the integrated compartment 15 when the second current collectors of the crane body 1 under the second trolley wire in the second passage direction reaches the second current collector is raised, it is abutted against the trolley wire, and,
The power collection device 11 for the direction of the passage 16 can be pulled down and separated from the trolley wire 12, and the trolley power supply traveling and the current collection / transport operation can be performed along the second lane. Incidentally, on the crane body 1, since it may also if necessary be self away from the trolley line, conventional may be preliminarily tower mounting the generator engine Similarly, also, there is no need In such a case, the mounting of the power generating engine can be abolished.

As described above, since the external power can be used, in the container yard, at least the crane body 1 of the tire traveling crane operating for the container stacking operation in the container stacking section 15 does not use the power generation engine. becomes possible, noise generator engine occurs throughout the day, it is possible to eliminate the pollution caused by exhaust gases. Further, trolley wire strut 13, can be also used like struts for illumination in the container yard.
In addition, the format of the trolley wire 12 and the overhead wire method may be changed to another arbitrary format. In addition, trolley wire 1
As shown in FIG. 3, a column 13 for supporting the containers 2 and 12 has a large number of container accumulation sections 15 in a container yard.
The passages 1 are provided every other row of the plurality of passages 16 formed therebetween.
If established at appropriate intervals along the 6 becomes yo Ikoto. As a result, the passage strut 13 has not been established, because it never passage of trailer 18 is inhibited by narrowing the passage width to the width of that amount container integrated compartment 15
This allows efficient use of the container yard.

[0013]

As described above, according to the present invention, the following effects can be obtained. (1) can use an external power, the container yard, tire traveling crane running for containers integrated work on least be co Ntena integrated compartment enables operation without using the electricity-generator engine, the generator noise use engine occurs throughout the day, it is possible to eliminate the pollution caused by exhaust gases, also trolley wire struts can be also used as a post for lighting, such as in the container yard.
