Abstract
The utility model discloses a central cutter individual drive system of a shield machine. The central cutter individual drive system comprises a main cutter disk, a mobile system of a central cutter mechanism and a driving system. The mobile system of the central cutter mechanism comprises a central cutter and a hollow rotary connector which are installed at the center of the main cutter disk. The mobile system of the central cutter mechanism is installed in the hollow rotary connector and oriented through a pulley. The driving system comprises a promoting system and a rotary system. The rotary system comprises a transmission shaft and a main bearing. The transmission shaft is installed in the hollow rotary connector. The promoting system is composed of a hydraulic cylinder fixed on an end plate of a shell. A connecting rod is installed on the hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of shield machine, relates in particular to a kind of shield machine center cutter independent driving system.
Background technology
Large-scale shield machine is mainly used in the constructing tunnel, and general employed swivel joint is solid structure, and it is big to take up room; The inner device that can not put into other again; Cause the space utilization of each device of shield machine inharmonious, need open a position and change the center cutter of centre drill, center cutter can not stretch simultaneously; If in construction, run into the difficult processing of situation of changing center cutter like this, reduced the operating efficiency of shield machine.
The utility model content
The purpose of the utility model is to provide a kind of shield machine center cutter independent driving system; Other the device such as centre drill of in the hollow space of swivel joint, packing into has solved the shield machine interior arrangement unreasonable, as need to open a position the center cutter of changing centre drill problem has been set.
The purpose of the utility model realizes through following technical scheme:
A kind of shield machine center cutter independent driving system; Comprise the operator dish; Comprise center cutter mechanism mobile system and drive system; Said center cutter mechanism mobile system comprises center cutter, the hollow swivel joint that is installed in operator disk center, and said center cutter mechanism mobile system is installed in the hollow swivel joint, is led by pulley; Said drive system comprises moving system and rotary system; Said rotary system comprises power transmission shaft and base bearing; Said driving sleeve is contained in the hollow swivel joint, and said moving system is made up of the hydraulic cylinder that is fixed on the end plate of outer cover, on the said hydraulic cylinder connecting rod is installed.
Further, the overcoat of the hollow swivel joint on the operator dish and load-carrying ring can rotate and have betwixt sealing relatively.
Further, said base bearing is installed on the bearing panel, and base bearing is connected with load-carrying ring through bolt.
The beneficial effect of the utility model is: owing to be provided with moving system, hydraulic cylinder can move to center cutter outside the storehouse, and center cutter is freely stretched; Owing to be provided with rotary system, strengthened the cutting dynamics of shield machine center cutter, improve shield machine and overcome the ability of tunneling resistance.
