Description

Coke oven grinds electric path pillar deformation compensation arrangement

Technical Field

The invention relates to a compensation device for providing tension for deformation of a support of a coke oven grinding channel device, and belongs to the technical field of coke oven grinding channel devices.

Background

The coke oven grinding channel support is a component part of coke oven coke guide coal car power supply equipment, a coal car grinding channel support is arranged in the base side direction of the upper part of the coke oven grinding channel support, a coke guide grinding channel support is arranged in the coke side direction of the lower part of the coke oven grinding channel support, and the bottom of the coke oven grinding channel support is connected with a coke oven coke side main support. Because of the moment influence, the force distance in the base side direction is larger than that in the coke side direction, and the coke oven mill channel support post is slightly deformed under the action of the force. Under normal temperature, the annual deformation is smaller than millimeter level and can be ignored. But under the action of high temperature in summer and the heat of the coke oven, the annual deformation of the support column in the oven area is several millimeters. After more than 10 years of deformation accumulation, the unidirectional inclination of the support column in the furnace area to the base side can be obviously seen, and the support column of the overhaul section outside the furnace area has no change. When the variation is larger than the adaptation of the sliding contactor to the grinding channel, the coal car grinding channel is required to be adjusted towards the coke side, and the coke blocking car grinding channel is required to be adjusted downwards. When the adjustment amount reaches the limit, the grinding channel leg adjustment has to be performed for several weeks. In addition, the deformation of each pillar in the furnace area is not uniform, and the uneven deformation makes the grinding channel appear S-shaped, thereby increasing the adaptation requirement of the sliding contactor to the grinding channel. The grinding channel can be timely adjusted to only solve the problem of deformation of the grinding channel, but the problem of deformation of the support column cannot be changed. The deformation of the support post causes the deformation of the grinding channel, so that the electric equipment of the coal car and the coke guide cannot normally supply power, and the normal production of the coke oven is influenced, thus the problem of the deformation of the support post is essentially solved.
