Detailed description of the invention
With reference to Fig. 1, oil-well rig single shaft list reduction box AC frequency modulation electric hoister, including gear reduction box 1, winch transmission device with send brill actuating device, in described gear reduction box 1, is respectively equipped with the first output shaft 2 being connected with winch and the second output shaft 3 being connected with drill feeding facility by gear drive；Respectively winch is crept into row cutting with sending.
Described winch transmission device includes the cage shaft coupling 4 for connection winch motor output shaft and the power shaft of gear reduction box 1, and the first output shaft 2 of described gear reduction box 1 is connected with winch；Realize winch is driven.
Described sending bores the drum shaft assembly 5 that actuating device includes being arranged on turntable, the both sides of described drum shaft assembly 5 are provided with hydraulic disc brake 6, the power shaft of described drum shaft assembly 5 is connected with the second output shaft 3 of gear reduction box 1 by gear coupling 7, the power shaft of described speed-changing gear box 1 is connected with automatic bit feed motor 8, and the output shaft of described automatic bit feed motor 8 is provided with air clutch 9.
Described winch motor includes the first motor 10 and the second motor 11 being arranged on gear reduction box 1 both sides, described first motor 10 and the second motor 11 are connected respectively through the power shaft of cage shaft coupling 4 with gear reduction box 1, and the power shaft of described gear reduction box 1 is transferred on the first output shaft 2 by gear engagement.
Described automatic bit feed motor 8 is connected with the second output shaft 3 of gear reduction box 1 by air clutch 9.So can main brake by air clutch 9.
This utility model electric winch has two big drive lines: one is synchronized the power shaft of one gear reduction box 1 of driving by two powerful alternating-current variable frequency motors i.e. the first motor 10 and the second motor 11 through cage shaft coupling 4, after double reduction, impart power to winch by output shaft；Two is driven by automatic driller, drum shaft assembly 5 is driven to complete to send drill-through journey after primary speed-down through the other end power shaft of gear reduction box 1, this winch eliminates traditional auxiliary brake mechanism, and adopting hydraulic disc brake 6 is auxiliary brake, and energy consumption of electrical machinery braking is main brake.It is good that this winch has drilling well performance, and overload performance is strong, Constant-power speed range is big, and utilization rate is high, and compact conformation, and volume is little, light weight.The winch of this version, can meet the demand of the high-power drilling well of high pulling torque, and its volume reduces simultaneously, and floor space reduces 15%-30%, and quality alleviates 20%-40%, meets integral hoisting and transport, greatly reduces manufacturing cost and freight.This has simplified the mechanism of whole drilling equipment to a great extent so that winch volume diminishes, structure is also more compact.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess, it is also possible to make a variety of changes under the premise without departing from this utility model objective, and the content after change still falls within protection domain of the present utility model.
