Duct piece hanging and conveying device applicable to miniature tunneling machine

Abstract

The invention provides a duct piece hanging and conveying device applicable to a miniature tunneling machine, and is applied to the technical field of a tunneling machine. The duct piece hanging and conveying device mainly comprises a walking mechanism, a hydraulic unit, a walking driving unit, a lifting arm, a lifting arm rotating oil cylinder, a lifting arm lifting oil cylinder, a duct piece rotating oil cylinder, a duct piece grasping seat and the like, wherein the walking mechanism is arranged on a rail beam, and realizes the forward and backward movement of a crane through the walking driving unit; the walking driving unit is fixedly arranged on the walking mechanism; the hydraulic unit is suspended on the walking mechanism and can forwards and backwards move along with the crane; alifting arm seat is connected with the walking mechanism through a pin and can leftwards and rightwards move; the lifting arm is connected with the lifting arm seat through a pin and can vertically move; one end of the lifting arm rotating oil cylinder is connected with the lifting arm seat; and the leftward and rightward swinging of the lifting arm is realized through the telescopic effect of the oil cylinder. The mechanism and the hydraulic cylinder are used for realizing the integration of grasping, lifting, rotation and placement in the construction process; the problem of narrow and small space of the miniature tunneling machine is solved; the work is reliable; the maintenance is convenient; the labor is liberated; and the efficiency is improved.

Description

technical field

[0001] The invention relates to a segment hoisting device suitable for miniature tunnel boring machines in the technical field of tunnel boring machines. Background technique

[0002] At present, in the design and construction of micro-tunnel boring machines, segment assembly is one of the key parts of the whole set of equipment, and segment hoisting is an indispensable part of the assembly system. Due to the narrow space of the tunnel, cranes are frequently used. The problem of segment lifting is particularly prominent, which greatly reduces the assembly efficiency and affects the normal excavation of equipment. The structure of the lifting device needs to be improved urgently. In the construction process of micro-tunnel boring machine, due to the narrow space and inconvenient manual operation, the use of traditional chain hoists can no longer meet the construction needs. A new problem to be solved urgently. Contents of the invention
