Out-of-the-cylinder sliding-contact-wiring-employed power supply device for circular stacker-reclaimer

Abstract

The invention discloses an out-of-the-cylinder sliding-contact-wiring-employed power supply device for circular stacker-reclaimer. The power supply device comprises a central cylinder, a turntable isarranged at the outside of the central cylinder, an annular cavity is arranged between the central cylinder and the turntable, at least one sliding contact wiring device is fixedly connected to the central cylinder, the sliding contact junction device is arranged in the annular cavity, a power supply is connected with the sliding contact junction device is through a conducting wire, and the sliding contact junction device is electrically connected with a power distribution cabinet of a stacker-reclaimer through a conducting wire. The power supply device disclosed by the invention has the advantages that the device changes the existing mode of cable connection for circular stacker-reclaimer power supply, the wiring is transferred from the inside of the central cylinder to the outside, the cable wiring is directly arranged on the outer side of the central cylinder through a cable leading device and the sliding contact junction device, and all cables are fixed and are not suspended, so that the labor intensity of workers can be greatly improved, and the equipment operating rate is improved.

Description

technical field [0001] The invention relates to stacking and reclaiming equipment, in particular to a power supply device for outer trolley lines of circular stacking and reclaiming machine cylinders. Background technique [0002] The circular stacker-reclaimer is composed of three parts: the stacker, the reclaimer and the central cylinder. During the reclaiming and stacking operations, there are two layers of stacking and reclaiming rotary mechanisms, so that the stacker and reclaimer The feeder forms two sets of non-interfering and relatively independent operating systems, realizing simultaneous stacking and reclaiming operations. [0003] The circular stacker-reclaimer is one of the most critical large-scale equipment in a cement plant. It can complete the stacking and mixing and reclaiming of limestone at the same time or separately. play a vital role. With the improvement of environmental protection requirements, in recent years, some power plants have begun to use ci...

AI Technical Summary

Problems solved by technology

[0005] 1. During use, due to its own weight and the non-stop swing caused by the rotation of the stacker when the stacker is working, this part of the suspended cable will cause strain inside the cable after a period of use. pull-off phenomenon;

[0006] 2. Since the slip ring is installed in the cylinder, it is difficult to dissipate heat and cannot be found in time after a fault occurs, and the space of the central cylinder is narrow and inconvenient for maintenance;

[0007] 3. The incoming power cable is connected to one side of the slip ring in the cylinder, which cannot fully exert the load capacity of the slip ring and shorten the service life of the slip ring;

[0008] 4. The stacker drives the slip ring in the cylinder to rotate 90 degrees per minute, and the equipment wear rate is high
