Embodiment 1

[0035] Embodiment 1 of the present invention provides a calibration tool for the shield machine shell, which is suitable for fine calibration of the shield machine shell a, wherein the shield machine shell needs to be rough-machined after being rolled to form, and then fine-tuned. Machining, fine correction refers to the last circle calibration in the finishing process, shield machine shell a includes front shield, middle shield and back shield. figure 1 It is a schematic structural diagram of the correction tool for the shield machine shell provided by the embodiment of the present invention. Such as figure 1 As shown, the calibration tooling of the shield machine shell includes: a support assembly 1 and a calibration assembly 4 . figure 2 It is a schematic structural diagram of the support assembly provided by Embodiment 1 of the present invention. Such as figure 2 As shown, the support assembly 1 includes: a reference post 2 and a reference seat 3, the first end 2a of ...

Embodiment 2

[0051] Embodiment 2 of the present invention provides a method for calibrating the shell of a shield machine using the calibration tool provided in Embodiment 1. Figure 6 It is a flow chart of the method for calibrating the shell of the shield machine provided by the embodiment of the present invention. Such as Figure 6 As shown, the method includes:

[0052] Step 1: Measure the perimeter of the shield machine shell along the outer wall of the shield machine shell. During specific measurement, multiple measurements can be made at different positions of the shield machine shell a, and the average value of the measurement results can be taken, so that the circumference of the outer wall of the shield machine shell a can be obtained more accurately.

[0053] Step 2: Draw the outline of the reference circle on the workbench. The circumference of the reference circle is the same as the circumference of the outer wall of the shield machine shell, and mark the center of the refer...

Abstract

The invention discloses a correcting tool of a shield tunneling machine shell and a method for correcting the shield tunneling machine shell and belongs to the field of shield tunneling machines. The correcting tool of the shield tunneling machine shell comprises a supporting assembly and a correcting assembly. The supporting assembly comprises a benchmark column and a benchmark base. The first end of the benchmark column is arranged on the benchmark base, the axis of the benchmark column coincides with the center line of the benchmark base, and the outer wall of the benchmark column is provided with a plurality of installation holes in the radial direction of the benchmark column. The correcting assembly comprises a first benchmark ring, a second benchmark ring, a positioning assembly, a plurality of supporting rods and a plurality of adjusting support rods. According to the correcting tool of the shield tunneling machine shell, when the radius of an inner circle of the shield tunneling machine is measured, measuring is carried out from the circle center of the benchmark column to the inner wall of the shield tunneling machine shell along the support rods, the radius of the inner circle of the shield tunneling machine shell can be accurately acquired, and the accuracy of exquisite circle correcting of the shield tunneling machine shell is further improved.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to a calibration tool for a shield machine shell and a method for correcting a shield machine shell. Background technique [0002] The shell of the shield machine is the key part of the work of the shield machine. The shell of the shield machine is divided into three sections: the front shield, the middle shield and the back shield along its axis from front to back. These three sections of the shield machine shell are all cylindrical The structure, and the front shield and the middle shield are connected by multiple propulsion cylinders, which are used to provide the forward driving force of the shield machine, and the middle shield and the back shield are connected by multiple articulated cylinders, which are used for the steering of the shield machine. When the shield machine is working, its main working process is the excavation of the cutter head in front of the front shield. Afte...
