Description

Technical Field

[0001] This utility model relates to the field of tunneling machine equipment technology, and in particular to a segment posture adjustment platform and tunneling machine equipment. Background Technology

[0002] With the development of urban underground space, irregular-section tunnel boring machines have been widely used in underground space development projects such as underground highway tunnels, pedestrian underpasses, subway entrances and exits, and underground integrated pipe corridors due to their higher space utilization, shallow overburden and cross-section applicability. Circular shield tunneling machines have relatively uniform segmentation, generally consisting of standard blocks, adjacent blocks, and K-blocks. Their shape, size, and center of gravity distribution are relatively uniform, and the assembly machine has a large working space. By using a traditional six-degree-of-freedom segment assembly machine in conjunction with a single hoisting or feeding machine, the segment grabbing, positioning, attitude adjustment, and assembly can be completed well.

[0003] However, for tunnel boring machines (TBMs) with irregular cross-sections, the cross-section size and shape are irregular. Considering limitations such as the grabbing capacity of the assembly machine and staggered assembly, the segment sizes and shapes vary, and the grabbing points differ. Furthermore, TBMs with irregular cross-sections typically employ one or more assembly machines working in coordination, especially with segments featuring a central support column. This further restricts the working space of the assembly machines, making grabbing difficult. Some assembly machines designed specifically for TBMs with irregular cross-sections suffer from limited cross-section applicability and versatility.

[0004] Therefore, it is necessary to provide a new segment attitude adjustment platform and tunneling machine equipment to solve the above-mentioned technical problems. Utility Model Content

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] This utility model proposes a segment attitude adjustment platform and tunneling machine equipment, aiming to solve the problem that existing equipment cannot be applied to the gripping of different segments in confined spaces.

[0032] Example 1

[0033] See Figure 1 and Figure 2 A segment attitude adjustment platform is disclosed for adjusting the attitude of the segment 10 to be installed. The segment attitude adjustment platform includes a platform body 1, a telescopic support assembly, and a side support assembly. The platform body 1 is slidably disposed in the tunnel and is used to connect with the tunnel boring machine body 6. The telescopic support assembly includes at least two support pieces 2 spaced apart on the platform body 1. The support pieces 2 can be raised and lowered in the vertical direction, and the two support pieces 2 cooperate to support the segment 10 to be installed. The first end of the side support assembly is connected to the platform body 1, and the second end of the side support assembly abuts against the tunnel sidewall 9. The second end of the side support assembly can slide along the tunnel sidewall 9 and is inclined upward along the length direction of the platform body 1. In actual operation, the extension and retraction of the two support components 2 are adjusted to adjust the posture of the tube segments under space constraints, thereby facilitating the gripping of the tube segments 10 to be installed. The second end of the side support component is inclined upward along the length of the platform body 1 so that the side support component can provide lateral support to the platform body 1 in a narrow space, preventing tipping and realizing the gripping of tube segments of different shapes in a narrow space.

[0034] Preferably, the telescopic support assembly includes four support units 2 located at the four corners of the platform body 1, thereby improving the accuracy of segment attitude adjustment.

[0035] The platform body 1 includes a main support plate 1.1 and an auxiliary support plate 1.2. The main support plate 1.1 has a first support surface 1.1.1, and a telescopic support assembly is disposed on the first support surface 1.1.1. The auxiliary support plate 1.2 is detachably connected to the main support plate 1.1, and has a second support surface 1.2.1, which is lower than the first support surface 1.1.1. The first support surface 1.1.1 and the second support surface 1.2.1 of different heights can accommodate pipe shapes with stepped surfaces, and the inclination of the second support surface 1.2.1 is set according to the pipe shape. The main support plate 1.1 and the auxiliary support plate 1.2 are detachably connected to facilitate the replacement of auxiliary support plates 1.2 with different second support surfaces 1.2.1, and to accommodate gripping operations of pipe segments of different shapes.

[0036] Specifically, the bottom surface 1.1.2 of the main support plate 1.1 is inclined upwards in a direction away from the auxiliary support plate 1.2. When the platform body 1 is set on an inclined surface in a narrow space, the main support plate 1.1 is located at the upper end of the inclined surface, and the auxiliary support plate 1.2 is located at the lower end of the inclined surface. The inclined bottom surface 1.1.2 on the main support plate 1.1 can fill the height difference of the inclined surface without occupying too much space, so that the first support surface 1.1.1 can be kept relatively horizontal. Then, the posture of the tunnel segment can be further adjusted by the extension and retraction of the support unit 2, thereby realizing the posture adjustment of the tunnel segment in a narrow space.

[0037] Furthermore, the segment attitude adjustment platform also includes sliding members 4. Sliding members 4 are provided at the four corners of the bottom surface 1.1.2 of the main support plate 1.1. The main support plate 1.1 is slidably mounted in the tunnel via the sliding members 4. In this embodiment, the sliding member 4 is a roller or a wheel. The segment attitude adjustment platform can slide along the tunnel via the sliding member 4 to ensure synchronous movement with the assembly machine 7.

[0038] In this embodiment, the side support assembly includes connecting arms and a support plate. The connecting arms are inclined upwards along the length of the platform body 1; the support plate is arranged along the width of the platform body 1. The support plate is detachably connected to the main support plate 1.1 via at least two connecting arms, and the support plate slides in contact with the tunnel sidewall 9. The support plate abuts against and slides in contact with the tunnel sidewall 9 to provide effective lateral support for the platform body 1. The detachable connection between the connecting arms and the main support plate 1.1 facilitates assembly and disassembly, reduces space occupation during transportation, and facilitates replacement of side support assemblies suitable for different tunnel cross-sections.

[0039] In this embodiment, the supporting unit 2 includes a telescopic drive component 2.1 and a supporting pad 2.2. The telescopic drive component 2.1 is mounted on the platform body 1, and its output end is connected to the supporting pad 2.2. The telescopic drive component 2.1 can drive the supporting pad 2.2 to move vertically, thereby adjusting the posture of the pipe segment supported on the supporting pad 2.2 to facilitate clamping by the assembly machine 7. In this embodiment, the telescopic drive component 2.1 is not limited to a hydraulic cylinder and can be replaced by other components to provide telescopic power.

[0040] In addition, the segment attitude adjustment also includes protective sleeves 5, which are installed on the platform body 1. Protective sleeves 5 are fitted around the outer periphery of the telescopic drive component 2.1, and the output end of the telescopic drive component 2.1 extends out of the protective sleeves 5 and connects to the support pad 2.2. The top of the protective sleeve 5 has a through hole, and the output end of the telescopic drive component 2.1 is slidably positioned in the through hole to avoid interference with the protective sleeve 5 during telescopic movement. The protective sleeve 5 effectively protects the telescopic drive component 2.1, ensuring the service life of the support unit 2.

[0041] The support unit 2 also includes a buffer pad, which is disposed on the support block 2.2. The buffer pad on the support block 2.2 serves both as a buffer and as a protection for the tunnel segments.

[0042] Example 2

[0043] The difference from Embodiment 1 is that the side support assembly includes at least two support arms 3 spaced apart along the width direction of the main support plate 1.1. The support arms 3 are detachably connected to the main support plate 1.1, and the end of the support arm 3 away from the main support plate 1.1 slides in contact with the tunnel sidewall 9 via a sliding member 4. The support arms 3 are inclined upwards along the length direction of the platform body 1. The combination of the inclined support arms 3 and the sliding member 4 can also achieve lateral support for the platform body 1, and the inclined support arms 3 further improve the support stability.

[0044] Example 3

[0045] See Figure 3 This embodiment provides a tunneling machine (TBM) device, which includes a TBM body 6, an assembly machine 7, a towing device 8, and a segment attitude adjustment platform as described above. The TBM body 6 has a fixed frame inside, the assembly machine 7 is mounted on the fixed frame, and the assembly machine 7 is equipped with a gripping component 7.1. The segment attitude adjustment platform faces the gripping component 7.1 and is connected to the fixed frame via the towing device 8. The TBM body 6 drives the assembly machine 7 and the segment attitude adjustment platform to move synchronously through the fixed frame. The TBM body 6, assembly machine 7, and towing device 8 are only structures disclosed in the prior art. See also... Figures 4 to 6These are schematic diagrams showing the structure of the assembly machine 7 when it grabs segment shape one, segment shape two, and segment shape three.

[0046] Since the tunneling machine includes the segment attitude adjustment platform as described above, it possesses all the beneficial effects of the aforementioned segment attitude adjustment platform, which will not be elaborated upon here.
