Firstly, placing a frame 1 in a constructed inclined shaft, hoisting a traction steel wire 15 through external hoisting equipment, simultaneously enabling the frame 1 to move up and down in the inclined shaft through the cooperation of travelling wheels 11 and rails 12, stopping working of the hoisting equipment when slag removal is needed, enabling a supporting leg device 16 to extend out and prop against the inner wall of the inclined shaft, supporting and fixing the frame 1, preventing the frame 1 from moving when a slag removal system 18 works, and realizing slag removal and rock breaking operations through the working of the slag removal system 18;
Then, after long-time work, the bucket teeth 4 on the scraper 26 are worn, and at the moment, the scraper teeth need to be replaced;
then, when the bucket tooth 4 is disassembled, the wrench is sleeved on the lockbolt 5, the wrench presses the locklink 53 to separate the lug 532 from the lockgroove 371, at this time, the lockbolt 5 is rotated to take out the lockbolt 5, the compressed spring can lift against the slide bar 31 in the process of taking out the lockbolt 5, at this time, the lower end of the slide bar 31 is separated from the bucket tooth 4 to release the limit, the spring moves upwards against the limit seat 33, the piston column 331 moves upwards to extract the gas in the upper chamber 35, the top column 36 is restored to release the fixation of the bucket seat 3 and the bucket tooth 4, at this time, the fixing rod 31 moves upwards, at this time, the fixing rod 32 loses the pressing force, the balance deformation body 43 and the compression deformation body 42 need to be restored, the force generated by restoring the balance deformation body 43 and the compression deformation body 42 can be restored against the fixing rod 32, and enter the bucket seat 3, and then the fixation between the bucket seat 3 and the bucket tooth 4 can be removed at this time;
Finally, a new bucket tooth 4 is placed on the bucket seat 3, the fixing strip on the bucket seat 3 is clamped with the groove on the bucket tooth 4, the bucket tooth 4 is prevented from sliding down from the bucket seat 3 under the condition of no fixing, the wrench is sleeved on the check bolt 5, the check link 53 is extruded, the check bolt 5 is fixed on the bucket tooth 4, after the wrench is removed, the elastic sheet 54 is restored to extend against the check link 53, the bump 532 is clamped in the check groove 371, the gasket 51 is simultaneously clamped against the check block 372, the gasket 51 is fully and perfectly attached to the saw-tooth-shaped and check block 372 after being extruded, the check bolt 5 is prevented from reversely loosening, the check bolt 5 is moved against the slide bar 31 in the process of fixing the check bolt 5, the extrusion cambered surface 312 on the slide bar 31 is abutted against the fixing bar 32, and further in the process of downward movement of the slide bar 31, the extrusion cambered surface 312 pushes the fixed rod 32 to slowly move, the tail end of the fixed rod 32 is further slowly clamped in the placing hole 41 of the bucket tooth 4, clamping and fixing with the placing hole 41 are completed, the lower end of the sliding rod 31 is clamped and fixed with the bucket tooth 4 again, the sliding rod 31 moves against the limiting seat 33, the piston column 331 on the limiting seat 33 slides and extrudes in the lower cavity 34, the jacking column 36 in the upper cavity 35 moves upwards, the jacking column 36 is correspondingly fixed with a groove on the bucket tooth 4, the fixation of the bucket seat 3 and the bucket tooth 4 is realized, the sliding rod 31 moves to drive the fixed rod 32 to move, the fixed rod 32 is communicated with the anti-loose connecting rod 53 to promote the balance shape body 43 to bulge, the gap between the bucket seat 3 and the bucket tooth 4 is sealed, dregs are prevented from entering the gap between the bucket seat 3 and the bucket tooth 4 when the device is used for skimming, meanwhile, the fixing rod 32 enters the placing hole 41, so that the clamping of the fixing rod 32 and the placing hole 41 is realized, and the whole fixation of the bucket teeth 4 and the bucket seat 3 is further completed.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
