Underneath type multiple-input rotation rotating table device

Abstract

The invention relates to the technical field of engineering machinery, particularly to an underneath type multiple-input rotation rotating table device. According to the invention, a power system is meshed with a second shaft bevel gear wheel through a bevel gear wheel at the front end of a first shaft, so as to transmit power to the second shaft and realize reversing from the vertical rotation tohorizontal rotation; a spur gear on the second shaft is used for transmitting power to a slewing bearing spur gear, horizontal rotation of the slewing bearing spur gear is used for driving a force taking table fixed on the slewing bearing spur gear to rotate horizontally; the force taking table is hollow, and an inner octangle is arranged at the upper part of the force taking table; an outer octangle at the upper part of a core supplementing wheel carrier is embedded inside the force taking table; drill pipe core supplementing wheels are mounted at the inner upper part and the lower part of the core supplementing wheel carrier, so as to drive a drill pipe inserted therein to complete rotation of the drill pipe. The underneath type multiple-input rotation rotating table device has the characteristics of stable running, big driving torque, long service life, flexible operation and the like.

Description

technical field [0001] The invention relates to a bottom-mounted multi-input rotary turntable device, in particular to a bottom-mounted multi-input rotary turntable device with high torque, belonging to the technical field of pile machinery in the construction machinery industry. Background technique [0002] Among the drilling rig transmission devices used in foundation treatment engineering drilling rigs in the construction industry, the power transmission devices are usually divided into two types: upper-mounted and lower-mounted, and the upper-mounted power transmission device consists of two or three motors and reduction devices. The top of the rod is powered by a frequency converter and the speed is changed. The power transmission device moves up and down with the drill pipe; the down-mounted power transmission device is installed The mounted type has a single-input single-stage or a single-input multi-head multi-stage gear reduction transmission device; a single-input...

AI Technical Summary

Problems solved by technology

The upper-mounted power transmission device has a high center of gravity and poor stability, especially the frequency converter speed adjustment cannot increase the torque; the lower-mounted single-input single-stage reduction transmission device cannot obtain a large transmission speed ratio and large torque due to the speed ratio limitation; The bottom-mounted single-input multi-stage reduction transmission device can increase the torque during deceleration, but if it is required to obtain a large speed ratio and large torque at the same time, it must go through a multi-stage reduction transmission, and its transmission device is relatively complicated.

In the process of use, the transmission speed ratio of the general single-input single-stage or single-input multi-stage gear reduction transmission device is relatively small, the transmitted torque is small, and it is not suitable for high-torque operations
