The invention relates to a disassembling tool suitable for an inner locking type drill rod, and relates to the technical field of pile foundation engineering machinery and drilling engineering machinery. The disassembling tool comprises a force applying driving head and a disassembling joint, wherein the force applying driving head is located above the disassembling tool, the disassembling joint is located below the disassembling tool, and a transmission pipe is connected between the force applying driving head and the disassembling joint; the transmission pipe comprises an inner pipe and an outer pipe, the inner pipe is fixedly connected with the disassembling joint, the outer pipe is fixedly connected with the force applying driving head, the inner pipe sleeves the outer pipe, and a torque transmission mechanism is arranged between the inner wall of the lower end of the outer pipe and the outer wall of the inner pipe in butt joint with the outer pipe; an upper limiting mechanism anda lower limiting mechanism are arranged on the inner pipe which sleeves the outer pipe, the upper limiting mechanism is fixedly connected with the inner pipe, the lower limiting mechanism is connectedwith the outer pipe, and a supporting spring sleeves the inner pipe between the upper limiting mechanism and the lower limiting mechanism; and a dismounting rod is arranged on the disassembling joint, and an elastic key block matched with a rotating groove of the inner locking type drill rod is arranged on the side wall of the lower part of the dismounting rod. According to the disassembling tool, the large torque and the large pulling force can be transmitted, and the internal locking type drill rod can be quickly disassembled.
Description
technical field [0001] The invention relates to the technical field of pile foundation engineering machinery and drilling engineering machinery, in particular to a disassembly tool suitable for internal locking drill rods. Background technique [0002] With the development of modern industry, large-diameter geological boreholes are more and more widely used, and these boreholes are used in many fields, such as: pile foundation field, mine field (wells for various purposes), sewage treatment field ( aeration wells), etc. At present, there are various drilling equipment and drilling techniques for large-diameter drilling. Available equipment includes rotary drilling rigs, full-face reverse circulation drilling rigs, percussion drilling rigs, diving rigs and ordinary positive circulation rotary drilling rigs, etc., among which At present, the most widely used are rotary drilling rigs and full-face reverse circulation drilling rigs. These drilling rigs have their own character...
