Description

Technical Field

[0001] The utility model relates to the technical field of TBM, and more specifically, to a conversion connection fixing device for a dual-mode TBM. Background Technique

[0002] A dual-mode TBM is a tunnel construction machine integrating technologies such as machinery, water conservancy, electricity, and hydraulics. It can quickly and flexibly switch tunneling modes according to different geological conditions and construction requirements to improve construction efficiency and safety. Generally, a dual-mode TBM has two or more tunneling modes, such as a shield mode and a TBM mode. The shield mode is suitable for soft soil strata, while the TBM mode is more suitable for hard rock strata. In the shield mode, the shield machine realizes the tunneling and support of soft soil strata by adjusting the propulsion and support of the shield shell. In the TBM mode, the tunneling machine breaks rocks and forms tunnels by rotating the cutter head and the propulsion system.

[0003] When the TBM tunnels through hard rock geology, it is necessary to install steel arch frames; when the TBM tunnels through soft surrounding rock, it is necessary to install steel pipe segments. When installing the steel pipe segments, a fixing device is required for temporary connection and fixation to facilitate subsequent fixation operations. The installation of traditional fixing devices is relatively cumbersome, especially the splicing structure thereon. Therefore, we have made improvements in this regard and proposed a conversion connection fixing device for a dual-mode TBM. Summary of the Invention

At this time, the limiting groove 202 is inserted into the limiting plate 201, and the limiting column 401 is inserted into the limiting hole 402. The first limiting wheel 5 and the second limiting wheel 601 on the upper arc-shaped fixing plate 1 are connected to the gear ring 8 and the annular sliding groove 809. The first hydraulic cylinder 3 retracts and drives the U-shaped clamping plate 302 to move through the transmission plate 301 so that the U-shaped clamping plate 302 is connected between the two support columns 4. Then install the motor 801.

[0058] When the steel pipe piece rack reaches below the vacuum suction cup 807, the third hydraulic cylinder 804 pushes the vacuum suction cup 807 downward so that the vacuum suction cup 807 sucks the steel pipe piece rack. The second hydraulic cylinder 7 at the corresponding position drives the pressing plate 701 to move towards the arc-shaped fixing plate 1. The motor 801 drives the gear ring 8 to rotate through the gear 802. When the steel pipe piece rack reaches the corresponding position, the second hydraulic cylinder 7 pushes the pressing plate 701 to move to fix the steel pipe piece rack.
