Problems solved by technology

[0003] In the existing TBM tool change operation process, the staff mainly enter the construction tunnel from the inside of the TMB to change the tool. The underground working environment is harsh, the operation is difficult, and the tool change efficiency is low, which is very prone to safety accidents
The whole project requires multiple tool changes, and each tool change will consume a lot of manpower, material resources, financial resources and time
Tool change affects the progress of the entire project

Abstract

The invention discloses a cutter changing platform used for a TMB positive hobbing cutter. The cutter changing platform comprises a hobbing cutter clamping claw, a connecting base connected with equipment, a Z-axis direction motion unit, an X-axis direction motion unit and a Y-axis direction motion unit, wherein motion in a Z-axis direction is realized by a lifting part of a slide platform; a nutlead screw mechanism driven by a motor enables the slide platform to realize motion in an X-axis direction; a Y-direction slide rod arranged on the slide platform drives a nut lead screw mechanism arranged between the motor and the Y-direction slide rod through the motor to drive the hobbing cutter clamping claw to realize motion in a Y-axis direction; a transmission shaft connected with the hobbing cutter clamping claw is connected with a step motor; and the step motor can rotate the hobbing cutter clamping claw to different angles. Under driving of each motor, the cutter changing platform precisely positions a cutter changing position to perform cutter changing work. The cutter changing platform can be used on a cutter changing robot, and avoids potential safety hazards in an existing manual cutter changing process. The cutter changing platform simplifies a cutter changing step, controls the cutter changing process by the controller, and is convenient for remote control.

Description

technical field [0001] The invention relates to the field of TBM (full-section rock tunnel boring machine), in particular to a positioning device for installing a TBM positive hob and a center hob and a method of using the same. Background technique [0002] The full-section rock tunnel boring machine (TBM for short) is a large-scale factory tunnel construction operation system integrating mechanical, electronic, hydraulic and laser technologies. The TBM method has the advantages of fast excavation speed, short construction period, good operating environment, less damage to the ecological environment, and high comprehensive benefits. It is an important choice for tunnel construction at home and abroad. With the implementation of large-scale infrastructure projects in my country and the excavation of a large number of long tunnels in the construction of railways, water conservancy, urban subways, oil pipelines and submarine tunnels, TBM construction technology has been rapidl...
