A method for dismantling the hinged oil cylinder of a shield machine in the hole

Abstract

An embodiment of the present invention provides a method for dismantling the hinged cylinder of a shield machine, including: constructing a propulsion cylinder bracket and a hinged cylinder bracket; driving the segment assembly machine to move the hinged cylinder bracket to the position of the hinged cylinder The lower part and fix the two together; remove the pin shafts at both ends of the hinged cylinder to separate the hinged cylinder from the shield machine; recover the red and blue cylinders downwards so that the hinged cylinder moves down with the bracket of the hinged cylinder; drive the segment assembly machine Slewing mechanism to drive the red and blue oil cylinder and its upper lifting plate, propulsion cylinder bracket, hinged cylinder bracket and hinged cylinder to rotate around the walking beam of the segment assembly machine; when the hinged cylinder on the hinged cylinder bracket rotates to When the segment assembly machine is under the walking beam, disassemble the hinged oil cylinder fixing device, and unload the hinged oil cylinder on the transport trolley on the bottom track. The hinged oil cylinder can be dismantled through the dismantling method provided by the invention, which can be operated quickly, efficiently and safely, and is easier to operate and implement.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a method for removing an articulated oil cylinder of a shield machine in a hole. Background technique [0002] The shield machine is a necessary equipment for subway tunnel excavation. After the tunnel construction is completed, due to some special reasons, it cannot slide to the open-air demolition shaft and use crawler cranes or truck cranes for demolition. However, due to the small space in the cave, the shield machine itself is not only very large, but also uses many hydraulic cylinders inside, and the dismantling environment is relatively closed, so it is not easy to dismantle. Usually, it is used on the shield inner wall of the shield machine. Welding lugs combined with manual hoists and slings to dismantle the hinged oil cylinder, the removal time is long and the safety cannot be guaranteed, so the dismantling of the shield machine in the hole is a common technical probl...

Problems solved by technology

However, due to the small space in the cave, the shield machine itself is not only very large, but also uses many hydraulic cylinders inside, and the dismantling environment is relatively closed, so it is not easy to dismantle. Usually, it is used on the shield inner wall of the shield machine. Welding lugs combined with manual hoists and slings to dismantle the hinged oil cylinder, the dismantling time is long and the safety cannot be guaranteed, so the dismantling of the shield machine in the hole is a common technical problem faced by many construction parties.
