Debris collecting device for vertical shaft excavation hole by drilling and blasting method

Abstract

The invention discloses a debris collecting device for a vertical shaft excavation hole by a drilling and blasting method. The debris collecting device comprises a positioning frame main beam, wherein the top of the positioning frame main beam is fixedly connected with a hoisting hook; the middle part of the bottom end of the positioning frame main beam is connected with a pushing oil cylinder; the bottom end of the pushing oil cylinder is connected with a collecting barrel; a driving motor is fixedly arranged at the top of the inner side of the collecting barrel; an output shaft of the driving motor is connected with a rotating shaft; the rotating shaft is connected with a spiral conveying reamer; the bottom edge of the spiral conveying reamer is fixedly connected with scraping teeth; and the positioning frame main beam, the pushing oil cylinder and the driving motor are connected with a control host. When in use, the debris collecting device is hoisted to the bottom of a shaft by using hoisting equipment, and at the moment, a swing oil cylinder and the pushing oil cylinder are in a retracted state; after the debris collecting device is in place, a hydraulic telescopic beam of the positioning frame main beam extends outwards and is tightly pressed against a reinforced concrete protection wall; and the driving motor operates to twist rock debris below the debris collecting device into the collecting barrel. The debris collecting device realizes automatic cleaning of the debris inside the vertical shaft excavation hole and is beneficial to improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of debris collection for shaft excavation holes, in particular to a debris collection device for shaft excavation holes by drilling and blasting. Background technique [0002] When using the drill and blast method to excavate hole piles, after the blasting is over, the rock is blasted into debris. In order to create a working face for supporting the rock wall and the next working cycle, the debris needs to be cleaned out of the bottom of the well. [0003] When excavating with manual hole-digging pile technology, it is necessary to manually use a shovel to put the debris in the small bucket, and then use the hoist to lift the keg out of the wellhead and dump it. In this process, affected by the speed of the hoist, the deeper and clearer the well The slower the speed of the slag, and when cleaning the slag, the staff at the bottom of the well are threatened by falling objects, and incidents of falling debris,...

Problems solved by technology

[0003] When excavating with manual hole-digging pile technology, it is necessary to manually use a shovel to put the debris in the small bucket, and then use the hoist to lift the keg out of the wellhead and dump it. In this process, affected by the speed of the hoist, the deeper and clearer the well The slower the speed of slag, and when cleaning slag, the staff at the bottom of the well are threatened by falling objects, and incidents of falling debris, tools, etc. causing personal injury and death happen from time to time

[0004] After the blasting, a large amount of toxic gas has accumulated at the bottom of the well. Before manual work starts, it needs to be ventilated for a long time. Wells over 10 meters need about half an hour of ventilation, and wells over 20 meters even need 1 hour of ventilation. Affected by the speed of slag discharge, it takes 2 to 3 hours to complete a slag removal, which restricts the improvement of work efficiency
