The utility model discloses a cooling structure for an input shaft of a reduction gearbox of a coal mill, which belongs to the technical field of cooling of reduction gearboxes of coal mills and comprises a lubricating oil pump, an oil inlet of the lubricating oil pump is communicated with a coal mill oil station, and an oil outlet of the lubricating oil pump is communicated with a main pipeline of the coal mill oil station. The coal mill oil station main pipeline comprises a first main pipeline body and a second main pipeline body which are arranged in the oil way direction, the second main pipeline body is communicated with one end of a cooling oil pipe and is perpendicular to the cooling oil pipe, and the other end of the cooling oil pipe is communicated with a bearing of an input shaft of a coal mill reduction gearbox through an oil pipe adapter. The cooling oil pipe of the input shaft of the reduction gearbox of the coal mill is reasonable in trend, smoothness of an oil way can be guaranteed, the temperature of the input shaft of the coal mill is effectively reduced, and meanwhile the problem of unsafe factors on site caused by additionally arranging a cooling fan is avoided.

The utility model discloses a tire for a tire type container crane, the tire is filled with filler so as to form a solid tire, the filler is formed by mixing, solidifying and hardening particulate matters and high polymer material AB glue, the particulate matters are waste tire particles formed by processing and cutting a waste tire, and the waste tire particles are filled with filler. The shape and size of the junked tire particles are 2CM * 2CM * 2CM, the usage amount of the junked tire particles filled in the tire is 35%-40%, and the junked tire has the advantages that the elasticity is high, the anti-ballast capacity is high, regular air-entrapping work does not need to be carried out on the tire, resource waste is avoided, and the equipment maintenance cost and the production cost are reduced.
