Description

Technical Field

[0001] The utility model relates to a novel matching structure of a large cover and a cooler for a synchronous roughing mill in the field of motor structure design. Background Art

[0002] The large cover of the synchronous roughing mill is of a split structure and is joined together through the middle joint surface. Since the speed of such motors is low and the load is large, the IC86W cooling method is usually adopted, that is, an air-water cooler with forced ventilation is provided at the top of the large cover. In order to avoid the joint surface, the traditional structure is that both ends of the joint surface 1 at the top of the cover sink and are flush with the top of the cover, so that the cooler installed on the top of the cover can be placed on the large cover of the rolling mill. The cooler is not a split-half structure, so an arched inner cavity needs to be formed inside the cooler through structural parts such as steel plate welding, so that the cooler does not interfere with the joint surface of the large cover. In this way, both the cooler and the cover need to be specially designed.

[0003] Please refer to Figures 1 to 3 ... The large cover 1 of the motor is of a split structure and is joined together by the flat steel 11 at the joint surface through bolts. In order to avoid the joint surface, the cooler 2 above the large cover needs to be welded by the first channel steel 36, the second channel steel 37, the first steel plate 31, the second steel plate 32, the third steel plate 33, the fourth steel plate 34 and the fifth steel plate 35 inside, so that the structural parts form an arched inner cavity at the bottom plate 21 of the cooler, so that the cooler does not interfere with the joint surface of the large cover. At the same time, please refer to Figure 4 ... In order to avoid the bottom plate of the cooler, the flat steel 11 at the joint surface at the top of the large cover must sink at both ends of the cooler matching position 111. Since the large cover is a large-size thin-walled welded structural part, the partial loss of the joint surface will affect the rigidity of the large cover. At the same time, there are too many welded structural parts in the cooler, and there is a risk of air leakage and water leakage. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel matching structure of a large cover and a cooler for a synchronous roughing mill, so as to change the complex matching design of the existing cooler and large cover, simplify the structures of the large cover and the cooler, and thus achieve the purpose of reducing the processing procedures and reducing the risks of air leakage and water leakage of the cooler.

[0005] A technical solution to achieve the above purpose is: a novel matching structure of a large cover and a cooler for a synchronous roughing mill, including a large cover of a motor and a cooler arranged on the top of the large cover of the motor;

[0006] The large cover of the motor is of a split structure, and flat steel for joining is provided at the top joint surface of the split structure; a channel steel penetrating along the joint surface direction is provided at the central position of the bottom surface of the cooler at the matching position with the joint surface of the large cover, the height of the channel steel is higher than the height of the flat steel, and the cooler bottom plates are welded on both sides of the channel steel.

[0007] Further, a gasket is provided at the bottom of the cooler bottom plate.

[0008] Further, the flat steel is in a rectangular strip structure.

[0009] The novel matching structure of the large cover and the cooler of the present utility model for the synchronous roughing mill enables the shape of the flat steel on the joint surface at the top of the large cover not to require special design and processing, and also reduces a large amount of welding work for the cooler. This structure is simple, economical, and reliable, thereby achieving the purpose of reducing the processing procedures and the risks of air leakage and water leakage of the cooler.

[0018] In order to better understand the technical solution of the present utility model, the following is a detailed description through specific embodiments:

[0019] Please refer to Figures 5 to 7, a novel matching structure of a large cover and a cooler for a synchronous roughing mill of the present utility model. A channel steel 4 is provided at the center of the bottom surface of the cooler 2 along the direction of the joint surface at the matching position with the joint surface of the large cover 1. The height of the channel steel 4 is higher than that of the flat steel 11, and the cooler bottom plate 21 is welded on both sides of the channel steel. The cooler bottom plates 21 are located on both sides of the flat steel 11 in a supporting manner to support the cooler. A gasket 5 is provided at the bottom of the cooler bottom plate 21 to ensure the waterproof and sealing performance.

[0020] Please refer to Figure 8 , the motor large cover is a split structure, and flat steels 11 for clamping are provided at the joint surface at the top of the split structure. Since the bottom of the cooler 2 adopts the structure of the through-channel steel 4, the structure of the flat steel 11 does not need to be adjusted to adapt to the bottom surface structure of the cooler. The flat steel 11 is a rectangular strip structure that covers the entire joint surface of the top surface of the motor large cover. Since the flat steel structure for clamping at this joint surface is completed, it will not affect the rigidity of the large cover.

[0021] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model and are not used as a limitation to the present utility model. As long as within the scope of the essential spirit of the present utility model, changes and modifications to the above-described embodiments will fall within the scope of the claims of the present utility model.
