Problems solved by technology
[0002] The thread at the end of the drilling tool is easily damaged during use. Now, a protective sleeve structure is usually installed at the end. However, the installation of the protective sleeve and the drilling tool is generally done manually. The installation and disassembly method is relatively traditional, and the operation is more complicated. Many, labor-intensive personnel, so it is necessary to provide a drilling tool thread protection sleeve installation and removal mechanism

A drilling tool thread bushing protection structure is characterized in that the drilling tool thread bushing protection structure comprises an adjustable variable frequency motor, a screw rod, an adjusting sleeve, fixing rods, a fixing disc, connecting rods, swing pieces and wrapping pieces; a screw rod is fixedly mounted at the power output end of the adjustable variable frequency motor; the lower end of the screw rod is sleeved with the adjusting sleeve capable of being adjusted in a rotating mode, the fixing disc is fixedly installed on the screw rod above the adjusting sleeve, the fixingrods are arranged on the periphery of the fixing disc at equal intervals, the four identical swing pieces are connected and installed outside the adjusting sleeve through connecting rods, the swing pieces and the wrapping pieces are integrally formed, and the two sides of the swing pieces are connected and installed through the fixing rods. The drilling tool threaded sleeve protection structure has the beneficial effects that the structure is simple, design is reasonable, the adjustable variable frequency motor is utilized, adjustment is flexible, dismounting and mounting can be fast achieved,the working efficiency is improved, the application range is wide, and the cost is low.
Description
technical field [0001] The invention relates to a device for geological exploration, in particular to the field of rotary motion devices, and in particular provides a protection structure for a threaded sleeve of a drilling tool. Background technique [0002] The thread at the end of the drilling tool is easily damaged during use. Now, a protective sleeve structure is usually installed at the end. However, the installation of the protective sleeve and the drilling tool is generally done manually. The installation and disassembly method is relatively traditional, and the operation is more complicated. Many, labor-intensive personnel, so it is necessary to provide a drilling tool thread protection sleeve installation and removal mechanism. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned many technical problems, and especially provides a drilling tool threaded sleeve protection structure. [0004] The invention provides ...
