Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0030] like image 3 Shown, power handling tools for radioactive sources, including thread tools and hex tools. The thread tool includes a thread tool head 3-1, a clamping device 3-2, a front end bearing 3-3, a transmission shaft 3-4, a rear end bearing 3-5, a reducer 3-6, a motor 3-7 and a battery 3- 8. One end of the transmission shaft 3-4 passes through the front end bearing 3-3 and is fixedly connected to the tail end of the threaded tool head 3-1 by the clamping device 3-2, and the other end of the transmission shaft 3-4 passes through the rear end bearing 3-5 and the deceleration The output shaft of the reducer 3-6 is connected, the input end of the reducer 3-6 is connected with the output shaft of the motor 3-7, and the battery 3-8 is electrically connected with the motor 3-7.

The invention provides an electric assembling and disassembling tool for a radioactive source of a logging instrument. The electric assembling and disassembling tool comprises a threaded tool and a hexagonal tool. The threaded tool comprises a threaded tool head, a clamping device, a transmission shaft and a motor, one end of the transmission shaft is fixedly connected with the tail end of the threaded tool head through the clamping device, the other end of the transmission shaft is connected with an output shaft of the motor, and the hexagonal tool has the same structure as the threaded toolexcept that the threaded tool head is replaced with a hexagonal tool head. The threaded tool and the hexagonal tool in the tool are both driven by the motor, an operator does not need to perform screwing operation manually, the operation speed is high, the risk that radioactive source falls off due to the fact that the operator worries about radioactive radiation to operate under the condition that the number of rotation turns is insufficient is avoided, the reliability is high, and meanwhile, control is convenient for the operator, operation is easy and convenient, the efficiency is high, andthe tool can assemble and disassemble the radioactive source used by a lithology density logging instrument.
Description
technical field [0001] The invention relates to tools for well logging instruments, in particular to an electric loading and unloading tool for radioactive sources of well logging instruments, which is suitable for assembling and disassembling radioactive sources of lithology density logging instruments. Background technique [0002] The radioactive source used in the lithology density logging tool will directly harm the body of the operator, so it is taken out of the source tank and installed on the instrument when the instrument is logging, and it is taken out and put back into the source tank after the logging is completed. The current loading and unloading tools are manually operated, and there is a possibility of misoperation, or the operator is worried about the radioactive radiation when the number of rotations is not enough, so the fixation is not in place, which is likely to cause accidents of radioactive sources falling, and the efficiency is low. Low. Contents o...
