Description

Technical Field

[0001] The utility model belongs to the technical field of mine emergency rescue, in particular to a demolition tool for mine emergency rescue. Background Art

[0002] In the complex and ever-changing environment of mine rescue, it is difficult for rescuers to adjust the working angle of demolition tools according to the actual rescue scenario and the shape of obstacles. For example, when it is necessary to cut or crush objects in a small space and at a tricky angle, fixed-angle tools may not be able to effectively contact the target object. Rescuers may need to spend extra time and energy to adjust their posture or find a suitable operating position, which is very disadvantageous in emergency rescue where every second counts, thereby reducing the efficiency of the rescue.

[0003] According to the authorization publication number CN216741606U, a demolition tool for emergency rescue in mines is disclosed. The cross bar is pushed to make the entire device movable under the action of the roller. When it moves to the position where crushing is required, the fixing rod is inserted into the soil by twisting the rotating seat to fix it and remove the pin. At the same time, the motor is started. The motor drives the rotating shaft to rotate in the shaft seat, so that the crushing head and the crushing piece are rotated. At this time, the electric telescopic rod also works, which drives the solid block to move back and forth and work simultaneously with the crushing head. The user holds the soft sleeve and pushes the slide plate to slide on the top plate through the side rod. At this time, the slider slides in the slide groove. The sliding of the slide plate enables the solid block and the crushing head to move and contact the position to be crushed and demolished, so that the crushing head crushes the obstacle (such as stone, etc.) by rotation, and then the solid block immediately hits it, thereby quickly expanding the crushing area, achieving the effect of efficient crushing and demolition, and buying time for rescue. After use, the slide plate is pulled back to its original position and fixed with the pin.

[0004] The above patent realizes the function of sliding adjustment crushing, but it does not have the function of multi-angle adjustment and lacks flexibility, which requires rescuers to spend extra time and energy to adjust their posture or find a suitable operating position, reducing the rescue efficiency. For this reason, we propose a demolition tool for mine emergency rescue. Utility Model Content

[0026] Working principle: When entering the rescue site, first, the fixed drill rod 33 is threadedly connected to the threaded sleeve 32 in the four sets of fixing parts 3 to rotate so that the fixed drill rod 33 can be adjusted up and down and drilled into the supporting ground to play a supporting role. Then, the second bevel gear 53 connected is driven to rotate by the execution end of the first motor 52. The rotation of the second bevel gear 53 drives the meshed first bevel gear 58 to support and rotate on the inner ring of the bearing of the first bearing base 57. The rotation of the first bevel gear 58 drives the first threaded rod 55 provided on the inner wall to rotate. The rotation of the first threaded rod 55 will make the sliding sleeve 59 threadedly connected to the top outer wall. Two groups of sliding support round rods 56 of the same structure are provided on the outer wall of the top of the limiting square plate 54 to perform linear lifting and lowering motion. When the sliding sleeve 59 performs linear lifting and lowering motion of supporting up and down, it drives the rotating platform 6 and the square protective shell 7 provided on the top of the rotating platform 6. The inner cavity of the angle tilting component 9 is provided to perform linear lifting and lowering motion of supporting up and down, which is convenient for adjusting the height of lifting.

[0027] The square protective shell 7 is further driven by the rotating table 6 to be provided with an angle tilting component 9 in the inner cavity for adjusting the lateral rotation angle. The rotating table 6 is an existing structure. The motor inside the rotating table 6 will output a stable torque to drive the rotating table 6 through the gear transmission to adjust the lateral rotation angle. The second motor 94 execution end drives the connected worm 99 to rotate. The rotation of the worm 99 drives the meshing worm gear 93 to rotate. Because the worm gear 93 connected to the outer wall side of the second bearing base 92 is rotated, the worm gear 93 is supported and rotated on the inner ring of the bearing of the second bearing base 92, and the worm gear 93 drives the second threaded rod 91 threadedly connected to the inner wall to rotate linearly. The second threaded rod 91 is linearly moved, and when the second threaded rod 91 is linearly moved, the rotating bearing 98 hinged to the second threaded rod 91 drives the support slide 97 to adjust the arc-shaped tilt angle, and at the same time, the top of the square connecting block 96 is hinged with a support slider 95 to perform limit support sliding adjustment when the support slide 97 adjusts the arc-shaped tilt angle, and the support slide 97 drives the crushing drill bit 10 provided on the outer wall to adjust the arc-shaped tilt angle, which is convenient for adjusting the tilt angle of the crushing drill bit 10 for crushing operations, and the operation is convenient. Rescuers need to spend extra time and energy to adjust their posture or find a suitable operating position, which reduces the rescue efficiency.
