Overturning method utilizing overturning device of mining dump truck box hopper

Abstract

The invention discloses an overturning method utilizing an overturning device of a mining dump truck box hopper. The overturning method comprises the following steps that: a box hopper clamp matched with a box hopper to be overturned in structure and size is selected, and the box hopper clamp is connected with a driving shaft of the overturning device of the mining dump truck box hopper; after theoverturning device of the mining dump truck box hopper is connected with the box hopper, a rotation center line is guaranteed to coincide with a gravity center line perpendicular to the side face ofthe box hopper, and in order to prevent the clamp from moving on the box hopper when the box hopper is overturned, a check block can be welded to the box hopper; 1.5 times of safety coefficients are reserved for strength levels of selected steel wire ropes and lifting rings; two hoisting tools are selected to hoist the box hopper through the steel wire ropes tied to hoisting arms, and the height needs to meet the overturning condition of the box hopper; and a motor controller is operated to enable a motor to operate, a driving fluted disc is driven to drive the box hopper clamp to rotate through a driving shaft, namely, the box hopper is overturned along with the box hopper clamp, and the box hopper is placed on the ground after being rotated by 180 degrees, so that overturning operation of the box hopper is completed. Therefore, the safety risk of overturning the mining dump truck box hopper can be reduced.

Description

[0001] The present invention is a divisional case with the application date of September 25, 2019, the application number of 201910910656.X, and the patent name of "Mining Dump Truck Box Bucket Turning Device". technical field [0002] The invention relates to the field of mine dump trucks, in particular to a turning method using a turning device of a box bucket of the mine dump truck. Background technique [0003] Mining dump trucks are non-highway dump trucks, which are used to transport coal mines and sand and gravel in non-highway field sites, such as large open-pit mines and water conservancy projects. In civil engineering, it is often combined with construction machinery such as excavators, loaders, and belt conveyors to form a loading, transporting, and unloading production line for loading, unloading, and transportation of earthwork, sand, and bulk materials. The bucket of mining dump trucks is relatively large. If the hole of the lifting cylinder on the back of the ...

AI Technical Summary

Problems solved by technology

[0004] In the process of turning over the box bucket, due to the relatively large volume and weight of the box bucket, the crane station is relatively close to the box bucket, and scraping accidents between the box bucket and the outrigger of the crane are prone to occur

In addition, during the overturning process, maintenance personnel need to enter the lower part of the bucket to remove the lifting point and replace the lifting point position, and the bucket is prone to tipping over, resulting in personal injury accidents
