Abstract: During daily disassembly and assembly and maintenance, large-scale mechanical equipment pin is time-consuming and labor-intensive, and many accidents may occur during such periods. So the work efficiency is low. The development of a special set of equipment to replace the operator’s manual disassembly and assembly of various types of shaft pin operations can not only improve work efficiency, reduce labor intensity, but also reduce personal injury accidents effectively. Taking the disassembly and assembly of oil drilling derrick and the base pin as an example, the energy of the disassembly pin is analyzed and calculated and the hydraulic pin disassembly device was developed by analyzing the structure of the pin shaft and site use. After the field trial, the effect turned out to be good. Taking the differences in the working parameters of the hydraulic stations of each drilling team into comprehensive consideration, the pressure and flow adjustment control box of the hydraulic system was developed, which enhanced the applicability of the device and promoted the application in the later stage.
