Embodiment 3

[0045] Embodiment 3: A shield machine, including the automatic supply system for the segment connecting bolts described in Embodiment 2, the ring support 1 of the automatic supply system for the segment connecting bolts is fixed on the moving part of the segment assembly machine On the frame 14, between the slewing frame 16 and the mobile frame 14, and on one side of the working platform 15 of the assembly machine, it is convenient for the personnel on the working platform to quickly take the segment connecting bolts. The central axis of the ring support 1 coincides with the central axis of the shield body of the shield machine to ensure that the automatic supply system can smoothly and efficiently transport the segment connecting bolts to the designated position. The segment assembly machine is located on the main beam 13, and other structures and Existing shields are the same or similar, such as Figure 1~3 shown.

Embodiment 4

[0046] Embodiment 4: A supply method of the automatic supply system of the segment connecting bolts for the shield machine as described in Embodiment 2 or 3, the steps are as follows:

[0047] S1: Fix the ring support 1 of the automatic supply system for the connecting bolts of the segment on the moving frame 14 of the segment assembly machine, and between the rotary frame 16 and the moving frame 14, to ensure the central axis of the ring support 1 It is collinear with the central axis of the shield body of the shield machine, which is convenient for quick access to the segment connecting bolts clamped by the bolt clamping mechanism when the segments are connected;

[0048] S2: Manually install the segment connecting bolts 19 into the bolt clamping mechanism 12 evenly distributed on the slewing ring 20, and the bolt clamping mechanism 12 clamps the segment connecting bolts 19 one-to-one, that is, a bolt clamping mechanism A segment connecting bolt is clamped, and the segment c...

Abstract

The invention discloses an automatic supply system and a supply method for segment connecting bolts, which solves the problem of low transport mechanization of segment connecting bolts in the prior art. The invention includes a bolt clamping mechanism and a ring support connected to the main beam structure of the shield machine. A slewing ring is rotated on the ring support. The driving device is connected, and the bolt clamping mechanism is arranged on the outer circumference of the slewing ring. The invention can automatically transport the connecting bolts of the segment to the designated position through the automatic supply system, which greatly reduces the labor intensity of the workers, improves the assembly efficiency of the segments, and enhances the construction safety.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to an automatic supply system and a supply method for segment connecting bolts. Background technique [0002] In the field of underground engineering, the application of shield tunneling method is becoming more and more extensive. In recent years, shield tunnels are moving towards the direction of large diameter and large buried depth. In shield construction, segment splicing is one of the most important procedures, and its splicing quality and efficiency are crucial. In the construction of 15-meter-level large-diameter shield tunneling, the diameter of the segment connecting bolts (axial connecting bolts and circumferential connecting bolts) used is about 40mm, and the mass of each bolt is about 10Kg. The number of bolts required on the sheet is about 80. At present, the installation process of segment connecting bolts is mostly done manually. Construction personnel need...
