Description

Technical Field

[0001] The invention relates to a fully automatic tunnel blasting excavation construction device, belonging to the field of tunnel construction. Background Art

[0002] Tunnels are the focus and key projects of highway and railway construction. With the development of railway construction and the advancement of science and technology, blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in the air, water, soil and rock media or objects to achieve the desired purpose. When explosive bags or charges explode in soil and rock media or structures, the soil and rock media or structures will be compressed, deformed, destroyed, loosened and thrown. During the tunnel excavation process, when blasting excavation is carried out, it is necessary to first drill multiple blast holes arranged in a circular direction on the blasting face, and then configure the explosive bags according to the pre-designed blasting parameters and put them into each blast hole, and then detonate them to complete the blasting construction.

[0016] Beneficial effects of the present invention:

[0017] Through the design of the moving mechanism, the transverse motor drives the transverse screw to rotate, and the rotation of the transverse screw drives the nut moving block to move through the action of the thread, and the movement of the nut moving block then drives the moving frame to move, and the movement of the moving frame will drive the synchronous movement of the transverse plate. Because the transverse plate is longer, when the moving frame and the transverse plate move synchronously, the transverse plate will first squeeze the vertical slide plate in the forward direction, and the end of the transverse plate will be squeezed together with the guide groove on the vertical slide plate. When the transverse plate and the inclined groove in the guide groove are squeezed together, the vertical slide plate will be pushed up. The vertical slide plate rises and synchronously drives the blocking plate to rise, and then the blocking plate in the forward direction is pushed up before the moving rod of the nut moving block, thereby avoiding the blocking plate in the forward direction from obstructing the moving action of the nut moving block, and the other fallen blocking plates can play a role of shielding and protecting the transverse moving groove, preventing falling rocks from entering the transverse moving groove and damaging the device.

[0018] Through the design of the sealing strip, the movable opening can be sealed and protected by the sealing strip. In addition, since it is only necessary to push the vertical slide plate up and down, the thickness of the horizontal board is relatively thin to meet the usage requirements. At the same time, the height of the movable opening matching the horizontal board will not be very high, so the sealing strip is sufficient to meet the sealing requirements.

[0019] The locking mechanism is designed so that when the device is not in use, the electric push rod contracts and pulls the electric drill to reset and move. The electric drill will no longer squeeze the inclined surface block one when it moves back, but will gradually squeeze the inclined surface block two. The inclined surface block two will gradually penetrate into the movable cavity, gradually insert into the gap formed between the engaging groove and the docking plate, and gradually squeeze the inclined surface of the docking plate, thereby pushing the docking plate to move. The movement of the docking plate will push the moving plate to move, and the movement of the moving plate will push the clamping rod and the plug rod to move. When the plug rod moves, it will first squeeze the plug groove on the outer surface of the sleeve, and then push the sleeve to move on the fixed column. When the sleeve moves, it will push the sliding seat to move outward through the movable rod. When the sliding seat moves, it will push the baffle to move through the connecting plate. Several baffles move synchronously to release the blockage of the groove opening, so that the clamping rod can be inserted into the groove. At the same time, the plug rod and the magnet in the plug groove are adsorbed together. At this time, the insertion rod and the magnet are adsorbed and the clamping rod and the side of the baffle are squeezed to form a limiting action of the fixed seat and the movable frame.

[0020] Through the design of the shielding protection mechanism, when the vertical motor and the vertical screw drive the fixed seat to move vertically, the fixed seat will pull the protective belts on the upper and lower sides. At the same time, the winding motors on both sides will rotate to realize the winding and extending actions of the protective belts on both sides. When the protective belt moves vertically, it will be guided by the guide members on both sides, thereby ensuring the stable movement of the protective belt.

[0021] Through the design of the guide member inclined surface structure, when the nut moving seat moves vertically in the vertical moving groove, the guide member can be pushed into the spring groove by squeezing the guide member inclined surface, so that the guidance of the guide member and the vertical movement of the nut moving seat will not interfere with each other.

Through the design of the shielding protection mechanism, when the vertical motor 24 and the vertical screw rod 23 drive the fixed seat 26 to move vertically, the fixed seat 26 will pull the protective belts 17 on the upper and lower sides. At the same time, the winding motors on both sides will realize the winding and extending actions of the protective belts 17 on both sides by rotating. When the protective belt 17 moves vertically, it will be guided by the guide members 18 on both sides, thereby ensuring the stable movement of the protective belt 17.

[0049] When in use, the lateral position of the mobile frame 13 is adjusted by the moving mechanism, and then the vertical height of the fixed seat 26 is adjusted by the vertical motor 24 and the vertical screw rod 23. Subsequently, the fixed seat 26 is locked on the mobile frame 13 by the locking mechanism to improve the stability of the fixed seat 26. Then, the electric drill 32 is started to perform drilling work. At the same time, the electric push rod 33 is used to push the electric drill 32 to move horizontally to achieve drilling work. In the process of the above-mentioned vertical motor 24 and the vertical screw rod 23 driving the fixed seat 26 to move and adjust, the shielding protection mechanism will shield and protect the vertical moving groove 14 to prevent the broken stones generated during drilling from entering the vertical moving groove 14 and causing interference and damage to the device.

[0050] The operation process of the moving mechanism is as follows: the transverse motor drives the transverse screw rod 3 to rotate, and the rotation of the transverse screw rod 3 drives the nut moving block 4 to move through the thread action, and the movement of the nut moving block 4 drives the moving frame 13 to move, and the movement of the moving frame 13 drives the transverse plate 12 to move synchronously. Because the transverse plate 12 is long, when the moving frame 13 and the transverse plate 12 move synchronously, the transverse plate 12 will first squeeze the vertical slide plate 8 in the forward direction, and the end of the transverse plate 12 will be squeezed together with the guide groove on the vertical slide plate 8. When the transverse plate 12 is squeezed together with the inclined groove 11 in the guide groove, the vertical slide plate 8 will be pushed up. The vertical slide plate 8 rises and drives the blocking plate 9 to rise synchronously, and then the blocking plate 9 in the forward direction is pushed up before the moving rod of the nut moving block 4, thereby avoiding the blocking plate 9 in the forward direction from hindering the moving action of the nut moving block 4, and the other fallen blocking plates 9 can play a role in shielding and protecting the transverse moving groove 2 to prevent falling rocks from entering the transverse moving groove 2 and damaging the device;

[0051] The operation process of the locking mechanism is as follows. When the electric drill 32 is drilling, the electric push rod 33 pushes the electric drill 32 to move and gradually extend out of the fixed seat 26. During the movement of the electric drill 32, the electric drill 32 will squeeze the inclined block 1 34, and the inclined block 1 34 will squeeze the inclined seat 35. The movement of the inclined seat 35 will push the moving plate 40 to move. The movement of the moving plate 40 will push the clamping rod 41 and the insertion rod 42 to move. When the insertion rod 42 moves, it will first squeeze the insertion groove 55 on the outer surface of the sleeve 47, and then push the sleeve 47 to move on the fixed column 46. When the sleeve 47 moves, it will pass through the movable rod 51 pushes the sliding seat 50 to move outward. When the sliding seat 50 moves, it pushes the baffle 54 to move through the connecting plate 53. The baffles 54 move synchronously to release the blockage of the opening of the groove 45, so that the clamping rod 41 can be inserted into the groove 45. At the same time, the insertion rod 42 is adsorbed with the magnet 56 in the insertion groove 55. At this time, the insertion rod 42 is adsorbed with the magnet 56 and the clamping rod 41 is squeezed with the side of the baffle 54 to form a limiting action of the fixed seat 26 and the movable frame 13. Under normal circumstances, the baffles 54 blocked at the opening of the groove 45 can play a shielding and protection role for the groove 45.

[0052] The operation process of the shielding protection mechanism is as follows: when the vertical motor 24 and the vertical screw rod 23 drive the fixed seat 26 to move vertically, the fixed seat 26 will pull the protection belts 17 on the upper and lower sides. At the same time, the winding motors on both sides will realize the winding and extending actions of the protection belts 17 on both sides by rotating. When the protection belt 17 moves vertically, it will be guided by the guide members 18 on both sides, thereby ensuring the stable movement of the protection belt 17;

[0053] By designing the inclined surface structure of the guide member 18, when the nut moving seat 21 moves vertically in the vertical moving groove 14, the inclined surface of the guide member 18 can be squeezed to push the guide member 18 to be stored in the spring groove 25, so that the guiding of the guide member 18 and the vertical movement of the nut moving seat 21 will not interfere with each other;

[0054] Through the design of the sealing strip 7, the movable opening 6 can be sealed and protected by the sealing strip 7. Moreover, since it is only necessary to push the vertical slide 8 up and down, the thickness of the horizontal plate 12 is relatively thin to meet the usage requirements. At the same time, the height of the movable opening 6 matching the horizontal plate 12 will not be very high, so the sealing strip 7 is sufficient to meet the sealing requirements.

[0055] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
