Full cross-section heading machine and dual drive system thereof

Abstract

The invention discloses a full cross-section heading machine and a dual drive system thereof. The dual drive system comprises an outer drive system and an inner drive system, wherein the outer drive system comprises an outer drive motor, an outer drive speed reducer, an outer ring gear and an outer power output gear ring; an output shaft of the outer drive motor is connected with an input shaft ofthe outer drive speed reducer; an outer shaft of the outer drive speed reducer is connected with the outer ring gear; the outer ring gear is connected with the outer power output gear ring; the innerdrive system comprises an inner drive motor, an inner drive speed reducer, an inner ring gear and an inner power output gear ring; the inner ring gear is positioned on the inner ring of the outer ring gear; an output shaft of the inner drive motor is connected with an input shaft of the inner drive speed reducer; an output shaft of the inner drive speed reducer is connected with the inner ring gear; and the inner ring gear is connected with inner power output gear ring. Because the outer power output gear ring and the inner power output gear ring can work independently, so that the total drive power configuration capacity is improved; and by adjusting the rotating speed of the two gear rings, relatively complex working conditions can be adapted.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a double drive system, and also to a full-face roadheader comprising the above double drive system. Background technique [0002] The full-face tunnel boring machine is a machine that uses a rotary cutter head to excavate a tunnel, breaks the surrounding rock in the tunnel and advances forward, so that the tunnel is formed sequentially. [0003] The cutterhead drive system is the core key component of the full-face roadheader, and the current cutterhead drive method usually uses a single drive system for driving. Since the full-face tunnel boring machine often needs to work under unpredictable conditions such as harsh environments and complex geology, in tunnel construction, the tunnel stratum structure is complex, and often encounter large buried depth, long distance, high water pressure, multiple fragmentation, and high strength. In rock tunnel conditions, tunne...

Problems solved by technology

Moreover, when encountering extremely hard rock, the bearing capacity of the single drive system is obviously insufficient. At the same time, extreme conditions such as landslides may easily cause the cutterhead to bear unbalanced loads, which will aggravate the wear of some cutters, causing the cutterhead and the corresponding bearings and ring gears to Reduced service life
