Description
Technical Field
The utility model relates to a cantilever entry driving machine blade disc driven technical field especially relates to a built-in drive of blade disc.
Background
The cantilever excavator is widely applied to the market, has high excavation flexibility and strong adaptability, and is widely applied to places such as roadways, cavern excavation and the like. A cutter head driving mode of the cantilever tunneling machine in the market mostly adopts a vertical shaft type motor to drive, and a motor, a speed reducer and other transmission modes are arranged in a cantilever structure. However, along with the increase of the hardness of the excavated rock, the diameter of the cutter head is increased, the required power is greatly increased, a double-motor driving mode is adopted, and the structural size and the weight of the driving device are greatly increased. When the swing cutting is performed, the unbalanced load causes excessive fluctuation of the driving torque, and damages are caused to the motor and the speed reducer.
SUMMERY OF THE UTILITY MODEL
Aiming at the problem that a double-motor driving mode is adopted in the existing cantilever excavator, the structural size and the weight of a driving device are greatly increased. When carrying out the swing cutting, uneven load can make the driving torque undulant too big, causes the technical problem of harm to motor and reduction gear, the utility model provides a built-in drive of blade disc.
In order to solve the above problem, the technical scheme of the utility model is so realized:
the built-in drive of cutter head comprises a speed reducer assembly and a drive system, wherein the speed reducer assembly is respectively connected with a cutter head mounting frame and a cutter head mounting arm, the drive system is arranged in the speed reducer assembly, and the speed reducer assembly and the drive system are integrally mounted in the cutter head mounting frame.
Preferably, the speed reducer assembly comprises a speed reducer, a speed reducer fixing end and a speed reducer output end are arranged on the speed reducer, a speed reducer fixing flange at the speed reducer fixing end is connected with the cutter head mounting arm, and the speed reducer output end is connected with the cutter head mounting frame; and a driving system is arranged in the speed reducer.
Preferably, the drive system includes an insertion hydraulic motor connected to a retarder in a retarder assembly.
Preferably, the speed reducer and the plug-in hydraulic motor are integrally mounted in the cutterhead mounting frame.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses overall structure designs compactly, embeds actuating system and reduction gear in the blade disc, reduces drive arrangement weight by a wide margin, has reduced the overall structure size to can realize quick and the variable speed and the switching-over of no impact through bayonet hydraulic motor, reduce the impact of unbalanced load to motor and reduction gear.
