Description

Technical Field

[0001] The invention relates to the technical field of shield construction, in particular to an auxiliary adjustment device for up and down floating of a shield segment. Background Art

[0002] With the vigorous development of my country's infrastructure industry, shield machines are widely used in engineering fields such as highways, water conservancy, subways, and railways. It is estimated that by 2022, the total length of tunnels in my country's subways, highways, railways, etc. will exceed 10,000 kilometers, of which medium-length and extra-long tunnels will account for about 2 / 3. The application of shield machines in tunnel engineering and the difficulty of posture control of shield machines when digging downhill are becoming more and more prominent.

[0003] The correct posture of the shield machine during excavation is crucial to the final formation of the tunnel. The cutter, as the core component of shield excavation, plays a vital role in the excavation process of the tunnel. When constructing under complex and harsh geological conditions, excavation must be carried out strictly according to the designed route to avoid unfavorable geological environment. When the shield machine excavates downhill, its posture has a large inclination, and the load conditions acting on the shield machine will be different from the horizontal state, which is prone to posture problems. The main body of the shield machine is in a "top-heavy" state, which makes it face a higher risk of head-cutting, especially under conditions such as soft geology, uneven hardness and unstable strata. It is more likely to have head-cutting problems. It can be seen that the research on the posture problems and adjustment technologies of shield machines is of great significance.

[0004] In view of the fact that the lifting amount of the shield machine during shield excavation cannot be offset by the head dive amount during the shutdown period, or the shield head dive will occur when the lifting amount is less than the head dive amount, the present invention designs a shield segment floating auxiliary adjustment device, which can adjust the floating of the shield segment and achieve the purpose of auxiliary adjustment of the shield head dive.

When the installation rod 421 stops moving, the display piece 423 stops moving. At this time, the position of the limit pin 422 on both sides of the display piece 423 can be observed, and the numbers of the positions on both sides can be added together, which is the number of times the shield segment 1 is adjusted.

[0050] In one embodiment, Figure 1-Figure 6 As shown, the segment auxiliary mechanism 2 includes:

One end of the connecting middle piece 213 is movably connected to the pipe segment adjustment component 22 , and the other end of the connecting middle piece 213 is movably connected to the adjustment limit component 23 .

[0057] Further, such as Figure 1-Figure 6 As shown, the segment adjustment assembly 22 includes:

The movement trajectory of the second connecting rod 232 is limited by the second fixed block 231, so that the second connecting rod 232 limits the movement trajectory of the connecting middle piece 213, ensuring that each movement trajectory of the segment adjusting rod 222 is not too large, thereby preventing the shield segment 1 from being over-pushed.

[0065] In one embodiment, Figure 1-Figure 6 As shown, two circles of second limiting grooves 6 are provided on one side of the shield segment 1 , and the second limiting grooves 6 adopt a circular structure.

When the installation rod 421 stops moving, the display piece 423 stops moving.
