[0045] Example 2
[0046] The present invention also provides a method for using the vertical shaft core drilling rig, the method comprising the following steps:
[0047] S1, first transport the vertical axis core drilling rig to the mining area, then start the diesel engine 3 to drive the belt to rotate, and the working box 5 performs mining in the vertical direction;
[0048] S2, secondly, the protection device 8 is lifted by the operating rod 7, and the steel pipe used for mining is connected to the connector 14 through the thread, and then the protection device 8 and the connector 14 connected to the steel pipe are rotated downward by the operating rod 7 to mine;
[0049] S3, finally the connector 14 is rotated in the opposite direction to be separated from the steel pipe, the connector 14 rises, and then a new steel pipe is added to be threadedly connected to the lower steel pipe, and the upper part is connected to the connector 14, and the operation is repeated.
[0050] Working principle: When the user uses the device, first transport the vertical axis core drill to the mining area, then start the diesel engine 3 to drive the belt to rotate, keep the working box 5 in the vertical direction, and carry out mining. Secondly, lift the protection device 8 through the operating lever 7, connect the steel pipe used for mining with the connector 14 through threads, and then use the operating lever 7 to rotate the protection device 8 and the connector 14 connected to the steel pipe downward for mining. Finally, the connector 14 is rotated in the opposite direction to disengage from the steel pipe, and the connector 14 rises. Then, a new steel pipe is added and threadedly connected to the lower steel pipe, and the upper part is connected to the connector 14. Repeat the operation. When the device encounters a harder rock and cannot be rotated downward, the protection device 8 will start to disconnect the protection shell 803 from the connector 14, protect the motor 6, and prevent the machine from being damaged. When the bottom steel pipe encounters a harder rock and cannot be drilled into, the protection shell 803 will shake. When the protection shell 803 shakes to a certain extent, the side of the protection shell 803 will push the trigger plate 807, and the trigger plate 807 presses the spring rod 1 806. At the same time, the spring rod 2 808 on the trigger plate 807 will rotate with the fixed rod 809 as the center of the circle, and at the same time drive the spring rod 3 810 to rotate, and press the lower pressure rod 811 downward, so that the linkage ring 813 pushes the lower sliding ring plate 815 to slide downward, and the push rod 817 at the bottom of the lower sliding ring plate 815 drives the push ring 81 8 and the inner cone ring 819 squeeze and fit the clamping device 9 below, the bottom of the inner cone ring 819 squeezes the hypotenuse of the right-angled trapezoidal slider 903 to squeeze the right-angled trapezoidal slider 903 in the direction of the spring, and at the same time drives the clamping block 905 to squeeze in the direction of the spring, cancels the control of the connecting head 14, and prevents the motor 6 from being damaged. When the device is in normal operation, the protective shell 803 rotates under the action of the rotating rod 801 and the connecting plate 802, and the lower sliding ring plate 815 rotates with the protective shell 803 under the action of the driving plate 816, and at the same time, the downward pressing slider 812 slides on the top of the linkage ring 813, and the working box 5 realizes the rise and fall of the motor 6 and the protective device 8 and other parts through the telescopic rod 12. The cleaning device 13 can be moved along the direction of the limit rod 11, wherein an airbag 1301 is arranged inside the cleaning device 13, and the opening of the airbag 1301 is opposite to the cleaning ring 1306, so that the pushing plate 1302 can squeeze the airbag 1301 when rising, and the airbag 1301 discharges the gas, and blows air to the protective shell 803 through the cleaning port 1307 on the cleaning ring 1306. During the rising process of the protective shell 803, the dust and dirt generated by mining will be brought up together. At this time, air is blown onto the protective shell 803 through the cleaning port 1307, and the dust and dirt on the protective shell 803 are blown away by the airflow, so as to prevent the protective shell 803 and the rotating shaft sleeve 1304 from being worn and causing the device to be repaired.
