Hollow gear-shifting planet speed reduction drive device

Abstract

The invention relates to a hollow gear-shifting planet speed reduction drive device which comprises a hollow water injection structure, a drive motor, a speed reducer, a gear shifting device and a floating nut. The hollow water injection structure comprises a water injection pipe and a center pipe; the lower end of the water injection pipe communicates with the center pipe; the center pipe penetrates through the whole drive device so as to form a channel for injecting slagging water; the drive motor is of a hollow structure and sleeves the periphery of the center pipe; and the output end of the drive motor is connected to drive a gear-shifting transmission sleeve. Therefore, the hollow gear-shifting planet speed reduction drive device provided by the invention has the multiple advantages of compact structure, high transmission efficiency, high carrying capacity, wide speed reduction range, large output torque and the like, the hollow structure capable of injecting the slagging water iseasy to realize, the demand of the compact machine body is met, a larger speed regulation space is obtained, the high-speed demand of a hole guiding working condition and the large-torque output demand of a hole chambering working condition are met at the same time, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction equipment, in particular to a hollow shiftable planetary reduction driving device. Background technique [0002] Raise shaft (raised shaft) drilling rig construction method has become one of the main construction methods in shaft construction in my country, and is widely used in mining, hydropower, transportation and other systems and fields. [0003] Raise well (raise) drilling rig is a wellbore excavation mechanical equipment that uses rotary drilling to break rocks and form holes and can reverse reaming. It uses drill pipes to drill pilot holes, and then uses reaming cutterheads to reversely ream the holes. [0004] At present, the driving device of the raise (raised shaft) drilling rig is mostly driven by an electric or hydraulic motor through a parallel shaft reducer. In order to obtain greater torque, multi-motor drive is used, and the structural size is large, a...

Problems solved by technology

[0007] The purpose of the present invention is to provide a hollow shiftable planetary deceleration drive device, which solves the problem that the drive structure of the parallel shaft reducer used in the drive device of the raise (patio) drilling rig in the prior art is bulky, resulting in a narrow and narrow structure for underground engineering. However, it is difficult to arrange the technical problem of the complete machine structure, and it also solves the problem that the drive reduction device of the raise (raised shaft) drilling rig in the prior art has only a single speed ratio and output torque, and cannot simultaneously meet the requirements of the pilot hole working condition Higher rotational speed and larger torque required by reaming conditions, low construction efficiency technical problems
