Background
The exploration machine is used for drilling cores, ore cores, rock scraps and the like into the underground so as to obtain underground geology, mineral resources and the like. The structure of the drilling machine comprises a tower, wherein a power head assembly is slidably arranged on the tower, the output end of the power head assembly is used for connecting a drilling rod, and the drilling rod continuously drills downwards after a driving cylinder on the tower drives and feeds the drilling rod; after the depth of a drill rod is drilled, the connection between the power head assembly and the drill rod is required to be released, and a new drill rod is additionally arranged between the output end of the power head assembly and the original drill rod, so that continuous drilling depth is realized.
The drill rod at the lowest end is internally provided with an inner pipe assembly, and a rock core drilled by the drill bit at the lowest end can continuously enter the inner pipe assembly through the inner cavity of the drill bit and is locked in real time. Before each drill rod is added, the drill rod is extended into a longer drill rod through a steel wire rope and a fisher connected with the steel wire rope to extract an inner pipe assembly; after the core and the like in the inner pipe assembly are extracted, the inner pipe assembly is put into a longer drill rod again, and then new drill rod is added.
After the exploration machine drills to a designated depth, the power head assembly is lifted by the driving cylinder on the tower frame to gradually lift the drill rods connected together. The method comprises the following specific steps: each time the driving cylinder lifts the height of one drill rod, the clamp at the bottom of the tower clamps the second drill rod at the upper part, so that the longer drill rod is prevented from falling back to the drilling hole; and then the uppermost drill rod is disconnected from the power head assembly and the second drill rod and is taken down, then the power head assembly is connected with the second drill rod again, the driving cylinder is lifted again, and the steps are repeated until all the drill rods are lifted.
Because the drill rod is made of metal, the drill depth is usually hundreds of meters or even thousands of meters, and the weight of the drill rods connected together is huge. At the beginning of lifting the drill, the drive cylinder on the tower is insufficient to complete the lifting power supply, and at this time, the wire rope of the lower fisher is often required to be connected to the power head assembly to assist in lifting the drill rod. Based on the above, the wire rope needs to be large in diameter to meet the pulling requirement. However, the steel wire rope also used as a salvaging inner pipe assembly has a larger weight when the rope body with a larger diameter is from the lower part to hundreds of meters or even to thousands of meters in depth, which increases coring load and energy consumption. For this reason, improvements in the lifting structure of the exploration machine are required in order to solve the above problems.
