Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] Refer to figure 1 The present invention provides a shield hob transport track, which does not need to be completely dismantled when the shield is advancing, and achieves the effects of saving manpower and speeding up the construction progress. The following describes the shield hob transport track of the present invention with reference to the accompanying drawings.

[0024] Such as figure 1 As shown, the shield hob transport track of the present invention includes a track set connected and supported on the shield shell, and the track set passes through the belt conveyor in the shield shell at the tail of the shield along the lower left of the shield advancing direction, and the cutter head The lower part of the drive 50 and the transition compartment 70 continuously extend from the tail of the shield to the head of the shield, so that the hob can be tran...

Abstract

The invention relates to a shield hob transport track. The shield hob transport track comprises a track group connected to and supported on a shield shell, wherein the track group continuously extendsfrom the shield tail of the shield to the shield head of the shield through a belt conveyor in the shield shell at the shield tail along the left lower side of the shield propulsion direction, the lower side driven by a cutter head and a transition cabin; and the bottom of the track group is fixed on the shield shell so as to be connected with the shield shell to form a whole. The shield hob transport track provided by the invention has the beneficial effects that the track group is connected to and supported on the bottom of the shell and keeps away from the operating space of an assembly machine and other equipment in the shield through the left side in the shield shell close to the shield tail, the lower side driven by the cutter head and the transition cabin, and mutual interference is avoided during normal working of the shield, thereby avoiding disassembly and accelerating the construction progress.

Description

Technical field [0001] The invention relates to equipment for the construction of a shield tunneling hard rock tunnel, in particular to a shield hob transport track for hob replacement belonging to the field of shield construction machinery. Background technique [0002] In China, the shield tunneling machine has been widely used in the construction of subways, large-diameter tunnels, and underground pipelines due to its excellent ground subsidence control, high excavation efficiency and wide stratum adaptability. The cutter head is one of the indispensable main components of the shield. In the shield construction process, especially in the hard rock environment, the wear of the cutter head hob is inevitable. In order to replace the severely worn hob, it is necessary to provide a reasonable transportation channel to transport the hob from the rear of the shield to the cutter head to complete the hob replacement operation. [0003] At present, the general hob transport track is in...
