Abstract

The invention relates to the technical field of culvert tunnel excavating equipment drive devices, in particular to a main drive device for a shield tunnelling machine with the diameter being 5 to 7 m. The main drive device comprises a shell, driving devices, main bearings, a cutter disc support and a seal structure; the shell is provided with the multiple driving devices and the main bearings which are correspondingly connected, the cutter disc support is arranged in the shell, and is connected with the main bearings through bolts in an occlusal manner, the seal structure is arranged betweenthe cutter disc support and the shell, and a cutter disc is arranged on the cutter disc support; each driving device comprises a motor and a speed reducer, the speed reducer is arranged on the shell in an occlusal manner, and the motor is connected with the speed reducer; small gears on the output ends of the speed reducers are engaged with teeth on outer rings of the main bearings; and through the technical scheme, the problems that in the prior art, the structure is complex and particular, the size is large, bearing is large, and purchasing maintaining cost is high can be solved.

Description

technical field [0001] The invention relates to the technical field of drive devices for culvert tunnel excavation equipment, in particular to a main drive device for a shield machine with a diameter of 5-7 meters. Background technique [0002] With the rapid development of modern transportation, more and more large-scale tunnels are being built, and the shield machines used for excavating tunnels are also tending to be large-scale; the existing large-scale shield machines are different due to their different mechanical structures and sealing arrangements. caused many problems: [0003] 1. The main driving device is installed in the center of the front shield, with special structure, limited volume and large load capacity; [0004] 2. The purchase price of imported equipment is expensive and the maintenance cost is high; [0005] 3. The technology of imported equipment is kept confidential, and there are great restrictions on use and maintenance. [0006] Aiming at the ab...
