The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

With reference to Fig. 1, in the utility model modular, the structure of deceleration well drilling hoist is, on winch base 9, symmetry is installed with left wallboard 2 and right wallboard 8, between left wallboard 2 and right wallboard 8, be jointly supported with barrel 4 by bearing, be installed with respectively in barrel 4 outers, two ends left dish stop 3 and right dish stop 7, be fixedly installed inner gear I 5 at barrel 4 internal circular surfaces and be fixedly connected with or integral production with barrel 4 with inner gear II 6(inner gear I 5, inner gear II 6); Inner gear I 5 and (or) inner gear II 6 are in transmission connection with at least one group of power plant module 1.

With reference to Fig. 2, Fig. 3, Fig. 4, every group of power plant module 1 includes a set of motor 10, coupler 11, power input shaft 12 and gear 14, bearing seat 13 is wherein arranged in left wallboard 2 or right wallboard 8, in bearing seat 13 inner circles, be installed with power input shaft 12, be that power input shaft 12 slides through bearing seat 13 by bearing, one end that power input shaft 12 stretches within left wallboard 2 or right wallboard 8 is installed with gear 14, gear 14 and inner gear I 5(or inner gear II 6) be connected by meshing transmission; One end that power input shaft 12 is positioned at outside left wallboard 2 or right wallboard 8 is in transmission connection by coupler 11 and motor 10, and motor 10 is fixed on winch base 9 by support.

What Fig. 1 showed is the mounting structure that two groups of power plant modules 1 provide power simultaneously; What Fig. 2 showed is the mounting structure that four groups of power plant modules 1 provide power simultaneously.

Cylindrical shell 4 is arranged on left wallboard 2, right wallboard 8 and with left wallboard 2, right wallboard 8 and is formed a space by bearing, and the gear 14 of power plant module 1 is installed in " in the space " that left wallboard 2, right wallboard 12, barrel 4 form.
