Abstract

The invention discloses a stable heat dissipation device for a power system of a shield tunneling machine, and relates to the technical field of shield tunneling machines. The stable heat dissipationdevice comprises a shield housing, the shield housing is internally provided with a power device, a cutter disc is fixedly connected to the right side face of the shield housing, the outer surface ofthe cutter disc is fixedly connected with a plurality of excavation cutters, the excavation cutters are evenly distributed on the outer surface of the cutter disc, a push mechanism is installed on theleft side face of the shield housing, a stabilizing mechanism is installed at the bottom of the shield housing, a transport mechanism is installed at the bottom of the stabilizing mechanism, the upper surface of the transport mechanism is fixedly connected with the bottom of the push mechanism, a first heat dissipation mechanism and a second heat dissipation mechanism are both installed inside the shield housing, and the first heat dissipation mechanism is located on the left side of the power device. According to the stable heat dissipation device for the power system of the shield tunnelingmachine, the phenomenon of vibration of the shield housing can be effectively avoided, and the advantages of good stability, good heat dissipation effect and being convenient to use by operators areachieved.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a stable heat dissipation device for a power system of a shield machine. Background technique [0002] The shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield machine is to build or lay the supporting segment of the tunnel while the tunnel boring machine is driving. It is different from the open construction method. The shield machine is based on the work. The principle is generally divided into hand-excavated shield, extrusion shield, semi-mechanical shield and mechanical shield. The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the axis of the tunnel. The shell of the cylinder assembly is the shield, which acts as a temporary support for the excavated unlined tunnel section, bears the pressure of the surrounding soil layer, and sometimes bears the press...
