Description

Technical Field

[0001] The utility model belongs to the technical field of cantilever roll cooling, and relates to a cantilever roll structure with a cooling cycle. Background Art

[0002] A cantilever roll refers to a roll with one end fixed and the other end suspended, which is usually used in a conveyor belt system as a mechanical device for supporting and transporting materials. In the conveyor belt system, one end of the cantilever roll is fixed on a frame, and the other end suspends a roll with a sprocket wheel. Power is transmitted through a chain to form a mechanism for strongly supporting materials. A commonly used cantilever roll consists of a roll sleeve, a roll shaft, a support base, a bearing housing, a motor, a reducer, a rotary joint, etc. The cantilever roll can be applied in the metallurgical industry. For example, when transporting molten metal blocks, the temperature will be relatively high, so the cantilever roll needs to be cooled down. In the prior art, there is a cooling method of injecting cooling water into the cantilever roll. For example, for the in-furnace cantilever roll of CN201410721096.0, cooling water is introduced through a water inlet joint and a cold water joint. However, there are some problems in the current prior art. First, currently, cooling water needs to be externally provided with a cooling tower or other cooling equipment, and a large number of pipelines are used to introduce cooling water into multiple cantilever rolls for cooling, and there is a sequence. Second, for the rotary joint outside the cantilever roll, the rotary joint needs to remain stationary relative to the external frame to prevent the pipelines connected to the joint from winding, while the connecting part needs to rotate synchronously with the discharging roll shaft. This results in most rotary joints being fixedly welded to the frame, which is not conducive to the maintenance of the rotary joint part. Therefore, the utility model proposes a cantilever roll structure with a cooling cycle. Summary of the Invention
