DETAILED DESCRIPTION

[0020] See also Figures 1 to 4 In an embodiment of the utility model, a quick layout device for blastholes in vertical shaft excavation includes a working disk 1, and a protective disk 3 is connected to the top of the working disk 1 through four connecting columns 2 to form a hanging disk platform that can be moved in the wellbore. A first bell mouth 4 and a second bell mouth 5 are respectively provided on the protective disk 3 and the working disk 1. A laser instrument 7 is embedded in the center of the lower end of the working disk 1, and a power supply unit 6 electrically connected thereto is provided. The power supply unit 6 is used to power the laser instrument 7. Through the irradiation of the laser instrument 7, the umbrella drill can be guided to quickly find the blasthole position, thereby improving the construction efficiency.

[0021] A spring column 10 is connected to the inside of the working disk 1, and one end of the spring column 10 is fixedly connected to a moving bar 9, and one end of the moving bar 9 is fixedly connected to a movable arc plate 8. The spring column 10 can be used to reset the movable arc plate 8. When the hanging plate moves along the wellbore as a whole, the movable arc plate 8 will drive the moving bar 9 to move toward the inside of the working disk 1 due to the compression of the inner wall of the wellbore. On the one hand, it will squeeze the spring column 10, and on the other hand, it will make the first conductive block 11 contact with the second conductive block 12 to complete the power supply to the laser instrument 7, so that it can work normally.

[0022] A rotating column 14 passes through and is rotatably connected to the lower end of the working disk 1. A gear 15 is fixedly connected to the upper end of the rotating column 14. A tooth groove 13 meshing with the gear 15 is provided on the moving bar 9. When the moving bar 9 rotates, the gear 15 is pushed to rotate synchronously. A baffle plate 16 is fixedly connected to the lower end of the rotating column 14. The upper surface of the baffle plate 16 contacts the lower surface of the working disk 1. When the gear 15 is rotated, the rotating column 14 is driven to rotate synchronously, thereby realizing the rotation of the baffle plate 16, and the laser instrument 7 blocked by it can be exposed.

[0023] A cleaning cotton 17 is fixedly connected to the upper end of the shielding plate 16. When the shielding plate 16 rotates, the cleaning cotton 17 is driven to wipe the surface of the laser instrument 7 to prevent dust accumulation from affecting its use.

[0024] The working principle of the utility model is as follows: when the hanging plate moves to enter the wellbore to work, when the working disk 1 enters the wellbore, it will squeeze the movable arc plate 8. When the movable arc plate 8 moves toward the inside of the working disk 1, on the one hand, it will drive the moving bar 9 to squeeze the spring column 10, and on the other hand, it will drive the first conductive block 11 to move. As the first conductive block 11 moves, it will contact the second conductive block 12 inside the working disk 1 to complete the power supply to the laser instrument 7, so that it starts to work. When the moving bar 9 moves, it will also push the gear 15 to rotate synchronously through the tooth groove 13. As the gear 15 rotates, the gear 15 will rotate through the rotating The column 14 drives the shielding plate 16 to rotate, thereby exposing the laser instrument 7. At this time, the laser instrument 7 can work normally. Through the irradiation of the laser instrument 7, the umbrella drill can be guided to quickly find the blasthole position, greatly improving the construction efficiency. When the hanging plate is not needed, the working plate 1 will move from the wellbore and lose the limit on the movable arc plate 8. Under the action of the spring column 10, the shielding plate 16 will return to its original position and re-shield the laser instrument 7 to prevent it from being damaged by accidental collision. At the same time, when the shielding plate 16 rotates to return to its original position, the cleaning cotton 17 arranged on its surface will wipe the laser instrument 7 to prevent dust from affecting the use of the laser instrument 7.
