Shield tunneling machine turn-around device and method

Abstract

The invention provides a shield tunneling machine turn-around device comprising a rotating platform, a launching table, a fixed gear and rolling gears. The rotating platform is rotatably arranged on the ground; the launching table is placed on the rotating platform; the fixed gear is fixed to the position, around the rotating platform, of the ground; and the rolling gears are engaged with the fixed gear, can roll along the fixed gear and are connected to the rotating platform through connecting pieces. The rolling gears of the shield tunneling machine turn-around device are connected with therotating platform through the connecting pieces, so that the relative position of the rolling gears and the rotating platform keep unchanged; and when the rolling gears roll around the fixed gear, therotating platform rotates around the center of the fixed gear along with the rolling gears, the launching table bearing a shield tunneling machine also rotates along with the rolling gears, and accordingly turn-around of the shield tunneling machine is achieved.

Description

technical field [0001] The invention is applied in the field of construction, and in particular relates to a U-turn device and a U-turn method for a shield machine. Background technique [0002] After the shield machine completes a single line in one section, it needs to turn around in the station and then return to excavate another line section. In the prior art, the shield machine generally adopts a split type or an integral type to turn around in the station. The split type disassembles and assembles the machine. It takes a long time, and the current integral transit is carried out by the combined construction of rollers, rails and jacks, which is time-consuming and labor-intensive. Therefore, it is necessary to provide a shield machine turning device, so as to save the time for turning the shield machine, speed up the construction progress, and save construction costs. Contents of the invention [0003] In order to save the turning time of the shield machine, speed up...

[0002] After the shield machine completes a single line in one section, it needs to turn around in the station and then return to excavate another line section. In the prior art, the shield machine generally adopts a split type or an integral type to turn around in the station. The split type disassembles and assembles the machine. It takes a long time, and the current integrated way of passing the station is carried out by the combination of rollers, rails and jacks. It is gradually pushed and turned, which is time-consuming and labor-intensive.
