Embodiment 6

[0077] Embodiment 6: A lifting method of the large-slope segment lifting system as described in Embodiment 5, the steps are as follows:

[0078] S1: The rubber wheel transportation device A adjusts the transported segment by rotating the leveling mechanism, so that the transported segment is always in a horizontal state during the transportation process; to complete the efficient transportation of the segment in the construction of a large slope tunnel.

[0079] S2: The rubber tire transport device A transports the segment to the working position of the segment quick unloading device B, and the segment quick unloading device B prepares for unloading the segment on the rubber tire transport device A; adjusts the automatic adjustment according to the slope of the tunnel leveling mechanism, so that the chassis assembly is always in a vertical state; specifically, one end of the leveling cylinder is connected to the trailer, and the other end is connected to the chassis assembly, a...

Abstract

The invention discloses a duct piece lifting system and a lifting method. The problem that an existing duct piece lifting system is not suitable for large-gradient duct piece lifting is solved. The duct piece lifting system comprises a rubber wheel conveying device, a duct piece quick unloading device, a suction cup type duct piece crane and a duct piece conveying device. The suction cup type segment crane comprises a walking frame body, an inclination angle adjusting mechanism is arranged on the walking frame body, a vacuum suction cup is arranged on the lower portion of the inclination angle adjusting mechanism, and an anti-falling mechanism is arranged on the vacuum suction cup. Synchronous lifting mechanisms are arranged on the two sides of a walking bottom frame of the duct piece conveying device, and limiting mechanisms are arranged on a sliding frame and a jacking frame. The material transportation system is an important component of shield method construction, and the design quality of the material transportation system is directly related to the whole machine performance and the overall construction. Compared with a conventional transportation mode, the novel material transportation system is adopted under the large-gradient working condition, the construction efficiency is greatly improved, the construction period is effectively shortened, meanwhile, the construction cost is reduced, and the construction safety and civilization are improved.

Description

technical field [0001] The invention relates to the technical field of tunnel segment transportation, in particular to a large-slope segment lifting system and a lifting method. Background technique [0002] At present, tunnel shield construction has been widely used in the development of underground space due to its advantages of safety and high efficiency. With the emergence of more and more complex engineering geology, higher requirements are put forward for the adaptability of shield tunneling machine / TBM. Conventional large-diameter shield / TBM construction is generally only suitable for tunnel slopes within 6°. When tunnel construction has continuous and variable large slopes (≮10°), conventional large-diameter shield / TBM will not be able to meet the construction excavation requirements. All key components of the mechanism need to be innovatively designed according to the geological conditions. Among them, the supporting material transportation system such as segment ...
