Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a transverse power supply device for a bridge reclaimer installed in a blending yard of a steelworks, a bauxite yard of a smelter, etc. The present invention relates to a bridge reclaimer traversal power supply device that protects the bridge reclaimer and improves the functionality of the bridge reclaimer.

[Conventional technology]

As shown in FIG. 3, the conventional bridge reclaimer has a bucket wheel 1 along a girder 101.
03 is movably provided, this carriage 107 traverses along the girder 101, and conveys the load such as ore scraped by the bucket wheel 103 in the direction of the paper.

In this bridge reclaimer traverse device, a traverse power supply cable 105 of an electrical component room 108 is connected to a power supply portion of the bridge reclaimer.

This transverse power supply cable 105 is connected to the girder 101
By providing a hanger rail 104 on the side surface of the hanger rail 104 and supporting the traversing power feeding cable 105 via a plurality of cable hangers 102 on the power feeding trolley 106 that runs traversing the hanger rail 104, the traversing power feeding cable 105 follows the movement of the carriage 107. It is designed to expand and contract like a rail.

[The problem that the idea attempts to solve]

However, when the bucket wheel 103 moves along the girder 101, ore may accumulate on the hanger rail 104 due to falling ore or coal falling from around the bucket wheel 103, or dust such as coal may become clogged. The movement function of the bucket wheel 103 was significantly degraded, and furthermore, the expensive traverse power supply cable 105 was cut or damaged due to the above-mentioned lumps of falling ore.

Therefore, the present invention was devised to effectively solve the above-mentioned problems, and it prevents the deterioration of bucket wheel moving machines etc. due to the above-mentioned injuries, and also prevents the transverse power supply cable from falling into mines, falling coal, etc. The present invention provides a transverse power supply device for a bridge reclaimer that can protect the bridge reclaimer from injury caused by the accident.

[Means to solve the problem]

The present invention provides a movable carriage of a bucket wheel along a girder, provides an electrical compartment on one side of the girder, and connects the electrical compartment and the power supply part of the bucket wheel with a transverse power supply cable. In the transverse power supply system for a bridge reclaimer, a fixed supporting tower is erected in the electrical component room, a movable supporting tower is erected in the carriage, and the traversal power supply cable is connected to the upper ends of both supporting towers. A tension wire is spanned and installed between both supporting towers, and the tension wire and the traverse power supply cable are connected integrally with a loop holder at a distance.

[Effect]

With the above configuration, a fixed supporting tower is erected in the electrical equipment room, a movable supporting tower is erected in the above-mentioned carriage, and the above-mentioned transverse power supply cable is stretched over the upper ends of both supporting towers, and the bucket wheel is Since it is installed at a sufficiently high position, it is possible to prevent damage to the lateral power supply cable due to falling mines and falling coal. Further, since the tension wire is installed between the two supporting towers, and the tension wire and the traverse power supply cable are integrally connected by a holder spaced apart, the power supply cable can be protected.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an overall view showing a traverse power supply device for a bridge reclaimer, which is an embodiment of the present invention.

The traverse power supply device of the bridge reclaimer 6 supplies electricity to a power supply portion of a bucket wheel 4 provided on a carriage 11 moving along a girder 5 through a traverse power supply cable 3.

As shown in the figure, an electrical component chamber 10 is fixedly provided on one side of the girder 5.
A traverse power supply cable 3 is extended from 0 and connected to a bucket hole 4 that is moved by a carriage 11.

A fixed supporting tower 2a having a predetermined height is erected on this carriage 11.
Similarly, movable supporting towers 2b are erected in each electrical component room 10. A traverse power supply cable 3 and a tension wire 1 are stretched between the supporting towers 2a and 2b, and the traverse power supply cable 3 and tension wire 1 are connected together with a loop holder 9 at an appropriate interval. ing.

The details will be explained with reference to FIG. Cable clips 7 for holding and guiding the traverse power supply cable 3 are provided at the upper ends of the fixed supporting tower 2a and the movable supporting tower 2b, respectively, as shown in the figure.

A traverse power supply cable 3 is spanned between the fixed supporting tower 2a and the movable supporting tower 2b via the cable clip 7.

Further, a tension wire 1 is installed along the transverse power supply cable 3 between the fixed supporting tower 2a and the movable supporting tower 2b.

As shown in the figure, this tension wire 1 is
One end is connected to the upper end of the fixed supporting tower 2a, the other end is connected to the upper end of the movable supporting tower 2b by a wire clip 8, and the transverse power supply cable is connected at a predetermined interval by a loop holder 9. 3 and holds the transverse power supply cable 3.

The lengths of the traverse power supply cable 3 and tension wire 1 are set such that the carriage 11 is at the right end of the gutter 5 in the figure, that is, the farthest distance from the electrical component room 10, and the distance between each supporting tower 2
The height of a and 2b is that the carriage 11 is the same as the electrical component room 10.
Transverse power supply cable 3 that is closest to the
The height is set so that the gutter 5 does not come into contact with the gutter 5 when it relaxes in the direction of gravity.

Next, the operation of the present invention will be explained.

Even if falling ore or coal falls near the bucket hole 4 when the carriage 11 moves through the gutter 5, the traverse power supply cable 3 is at a high position and will not be damaged by these. In addition, since the tension wire 1 is installed between each supporting tower 2a and 2b, and the tension wire 1 and the traverse power supply cable 3 are integrally connected with a loop holder 9 at intervals, the traverse power supply cable 3, it becomes possible to reduce the tension applied, and it becomes possible to prevent accidents such as cutting due to the tension. In addition, this invention eliminates the need for hanger rails, cable hangers, etc.
The structure becomes simple and it is possible to prevent the running function of the carriage 11 from deteriorating.

[Effect of idea]

The present invention has the following excellent effects.

(1) Because expensive cable hangers etc. are not used,
This brings down the production cost of the entire device.

(2) The structure of the power supply device is simplified, and it is possible to prevent damage to expensive lateral power supply cables.
