Design method for large dual-chamber skipping bucket and dual-chamber skipping bucket

Abstract

The invention relates to a design method of a large double-cavity skip and a double-cavity skip. The skip includes: a frame, a bucket box is arranged in the frame, and the lower part of the bucket box is connected to a chute. The chute is provided with a fan-shaped gate, the horizontal section of the bucket box is rectangular, the ratio of the long side to the short side of the rectangle is equal to or close to 2, and at the midpoint of the two opposite long sides of the rectangle Set a partition, the distance from the upper edge of the partition to the upper edge of the bucket box is between 0.5 and 0.6 of the height of the bucket box; the distance from the lower edge of the partition to the lower edge of the bucket box is a maximum of 2-5 times Dimensions of material particles. The large-scale double-cavity skip designed according to the design method of the present invention uses the partition plate, the strength of the bucket box wall is greatly increased, and the peripheral reinforcing ribs are reduced, so that the weight of the whole bucket box is obviously reduced. The design and structure of the large double-cavity skip is reasonable, and the phenomenon of "bulging belly" no longer occurs during operation, ensuring safe and reliable operation.

Description

technical field [0001] The present invention relates to a design method of a large-scale double-cavity skip and a double-cavity skip, which is a design method and equipment of mining mechanical equipment, and a design method and equipment of lifting equipment used for lifting materials in vertical shafts of mines. It is a design method for large skips with a capacity greater than 50 tons. Background technique [0002] With the continuous increase of modern large-scale mines, mining skips are also developing in the direction of large-scale. Existing skips generally have a capacity of less than 45 tons. There are still many technical difficulties in designing large skips exceeding 50 tons, such as the problem of "bulging" of the skip. The larger the capacity of the skip, the more serious this problem will be. . Most of the traditional skips used in mines are single-cavity, and the horizontal cross-section of the bucket box is rectangular. The key to designing the bucket box...

Problems solved by technology

However, because there is no theoretical support for the setting of the partition, the size of the partition is relatively random, resulting in many new problems during the use of the bucket box with the addition of the partition, such as: uneven loading, unsmooth discharge, and the partition itself. "Swollen belly" phenomenon, etc.

Due to the emergence of these problems, most bucket box designers dare not use partitions to strengthen the strength of the bucket box wall
