Milling wheel transmission system of double-wheel slot milling machine for underground diaphragm wall construction

Abstract

The invention discloses a milling wheel drive system of a double-wheel slot milling machine for underground continuous wall construction. A motor gear is mounted on a rotating shaft of a hydraulic motor, the motor gear is in meshed connection with a first gear of coaxial double gears, a second gear of the coaxial double gears is in meshed connection with a first middle gear, the multiple middle gears are in meshed connection and series connection with one another, the final middle gear is in meshed connection with an output gear, the two ends of a center rotating shaft of the output gear are connected with input ends of two planetary reducers, and the hydraulic motor, the motor gear and the coaxial double gears are arranged outside a milling wheel shell. The milling wheel drive system of the double-wheel slot milling machine for underground continuous wall construction has the advantages that the transverse position is convenient to adjust, the output rotation speed is convenient to adjust, high-quality rotation power transmission can be achieved, the transmission path is linear, the rotation power of the two planetary reducers is absolutely synchronous and of the same direction, and the use requirement that the whole transmission system is applied to a narrow environment is met.

Description

technical field [0001] The invention relates to a milling wheel transmission system, in particular to a milling wheel transmission system of a double-wheel slot milling machine for underground continuous wall construction. Background technique [0002] Due to its high structural rigidity, good integrity, high anti-seepage performance, little impact on the surrounding foundation, and wide adaptability to strata, the underground diaphragm wall has been widely used in three-dimensional transportation, water conservancy reservoirs, urban high-rise buildings, and nuclear power safety projects. Rapid development and application. [0003] The double-wheel groove milling machine adopts the milling process and is currently the most advanced special anti-seepage continuous wall construction equipment. The whole machine is composed of a lifting system, a frame, a milling wheel system, a deviation correction system, a mud slag discharge system and a hydraulic power system. The double-w...

Problems solved by technology

The former has a compact structure, but limited by the space, the specific power of the milling wheel is small, and because the power transmission system is highly integrated, the system design strength is restricted, and the system is relatively delicate; while the latter needs to solve the transmission between the motor and the reducer. System design problem, because the transmission system can only be set as a "flat" structure so as to pass through the narrow empty space in the middle of the milling wheel. The reason inevitably restricts the reliability and durability of the milling machine itself.
