Description

Technical Field

[0001] The utility model relates to the technical field of iron and steel casting, in particular to a lubricating device for the supporting rollers of a circular cooling machine. Background Art

[0002] In the field of iron and steel casting, a circular cooling machine is a commonly used device in the sintering process. The inner and outer rings of the circular cooling machine are each supported by multiple supporting rollers. Usually, a relatively heavy circular cooling machine weighs about more than 2,000 tons. Therefore, it is crucial to ensure the normal and stable operation of the supporting rollers. During engineering design, oil lubrication is required for the supporting rollers. Therefore, an oil groove is provided under each supporting roller so that when the supporting roller rotates, it can enter the oil groove for lubrication. However, in actual use, since the oil groove is designed with a large open surface for the convenience of the supporting roller to enter, and due to the outdoor setting of the equipment, the oil groove is often easily contaminated, and the accumulation of ash and dust in the oil groove is serious. As a result, individual supporting rollers often have insufficient lubrication, leading to a large running resistance of the circular cooling machine. At the same time, there is also a problem that since the oil groove is arranged under the supporting roller, it is relatively dangerous for manual cleaning. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a lubricating device for the supporting rollers of a circular cooling machine, which can be easily disassembled to clean the oil groove and ensure the lubrication of the supporting rollers of the circular cooling machine.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A lubricating device for the supporting rollers of a circular cooling machine, comprising:

[0006] An oil groove, on one side edge of which a support frame is installed. On the support frame, an upper roller and a lower roller are installed in parallel in the vertical direction. An oil cloth is wound around the upper roller and the lower roller and is immersed in the lubricating oil in the oil groove;

[0007] A cover plate, which is detachably fixed above the oil groove and has a gap for the oil cloth to pass through between it and the oil groove;

[0008] A fixing clip, which is fixedly connected to the lower part of the oil groove and is used to fixedly connect the oil groove to the support of the supporting roller of the circular cooling machine.

[0009] A further improvement of the utility model is that the fixing clip includes an L-shaped clamping plate. A bolt is fixed on the outer side surface of the clamping plate. The bolt passes through and is rotatably connected to the lower part of the oil groove and is locked and fixed by a nut. A baffle parallel to it is fixed on the clamping plate, and a threaded hole is provided on the baffle. A pressing bolt is threadedly connected to the baffle.

[0010] A further improvement of the present utility model is that a U-shaped groove is provided at the upper end of the support frame, and both ends of the roller shaft of the upper rotating roller are inserted into the U-shaped groove and locked and fixed to the support frame by nuts.

[0011] A further improvement of the present utility model is that one side of the bottom of the oil groove is inclined in a slope shape towards the lower rotating roller.

[0012] A further improvement of the present utility model is that the cover plate is locked and fixed to the oil groove by bolts.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing an upper rotating roller, a lower rotating roller and an oil cloth, the lubricating oil is transferred to the support roller for lubrication through the contact between the oil cloth and the support roller. At the same time, a cover plate is provided to protect the oil liquid in the oil groove, and a fixing clip is provided to fix the oil groove to the bracket of the support roller, which is convenient for disassembling the oil groove to replace the oil cloth and cleaning.

[0015] By setting the fixing clip as an L-shaped clamping plate and passing bolts through the lower part of the oil groove, the fixing position of the oil groove can be adjusted according to needs to ensure that the oil groove can be installed and fixed according to the actual situation of the bracket.

[0016] The upper end of the support frame of the present utility model is set as a U-shaped groove, and both ends of the upper rotating roller are inserted into the U-shaped groove and locked and fixed by nuts, so that the installation position of the upper rotating roller can be adjusted according to needs to ensure the stable working state of the oil cloth and avoid the oil cloth from being slack and unusable.

[0017] By setting the bottom of the oil groove to be inclined towards the lower rotating roller side, the waste of the oil liquid in the oil groove can be avoided and it can be effectively used. Description of the Drawings
