Description

Technical Field

[0001] The utility model relates to the technical field of tunnel shield construction measurement, in particular to a measurement hanging basket of a shield machine. Background Art

[0002] Shield construction technology is widely used in modern tunnel construction. Precise control of the shield machine's direction of advance is crucial during tunnel excavation. The precise formation of the tunnel during shield construction relies on the machine's stable progress along the planned route. To ensure this, real-time, accurate measurement of the shield machine's position and direction is essential.

[0003] Currently, the commonly used measurement baskets have a significant limitation: their mounting plates can only be installed in a fixed orientation. This means that the measurement basket can only be installed in an existing tunnel in a fixed structure. To obtain accurate and comprehensive shield machine position measurement data, it is often necessary to install the measurement basket at multiple locations in the existing tunnel to monitor the shield machine from different angles and positions. In view of this, we propose a measurement basket for shield machines. Utility Model Content

[0004] The main purpose of the utility model is to provide a measuring hanging basket for a shield machine, which can solve the problems raised in the above background technology.

[0006] A threaded rod, wherein the inner wall of the arc-shaped groove is movably connected to the threaded rod, and the outer wall of the threaded rod is fixedly connected to the support plate;

[0007] A washer is sleeved on the outer wall of the threaded rod, and a hexagonal nut is threadedly connected to the outer wall of the threaded rod;

[0008] A placing plate is provided, wherein the outer wall of the supporting plate is rotatably connected to the placing plate, and the top of the placing plate is fixedly connected to the adjusting plate.

[0009] Preferably, the inner wall of the adjustment plate is threadedly connected with an adjustment screw, and the inner wall of the support plate is slidably connected with a sliding block, which is C-shaped and welded by an L-shaped plate and a square plate.

[0010] Preferably, the inner wall of the connecting plate is detachably connected to a connecting piece, the top of the connecting piece is threadedly connected to a second hexagonal nut, and a ring platform is provided on the connecting piece, and two groups of the ring platforms are provided.

[0014] The utility model provides a measuring hanging basket for a shield machine, which has the following beneficial effects:

[0015] (1) The measuring basket of the shield machine is matched with the supporting structure through the arc groove. By loosening the hexagonal nut one, the position of the threaded rod can be moved on the arc groove, driving the support plate to move, and at the same time changing the angle of the support plate, thereby changing the angle of the placement plate, making it convenient to place the measuring equipment at different positions and angles. By loosening the hexagonal nut two, the connecting plate can be rotated on the connecting piece, changing the angle between the connecting plate and the main plate, which can meet the needs of installing the measuring basket at different positions and angles in the tunnel, thereby better adapting to the complex construction environment.

[0016] (2) The measuring basket placement plate of the shield machine can be released from the limit by loosening the adjusting screw, so that it can rotate on the support plate. When it rotates to be parallel to the support plate, slide the sliding block to the top of the adjusting plate, and then rotate the adjusting screw to make the adjusting screw contact with the sliding block to limit the sliding of the sliding block, thereby fixing the angle of the placement plate and completing the storage of the placement plate, reducing the space occupied by the device in the tunnel.

[0024] See also Figure 1 - Figure 3 The utility model proposes a measuring hanging basket of a shield machine, comprising a main board 1, which is a semicircular ring design. The outer wall of the main board 1 is fixedly connected to a connecting plate 2. An arc groove 3 is provided on the main board 1, and the arc groove 3 is a through groove design. A supporting structure 4 is provided on the arc groove 3. The supporting structure 4 comprises a threaded rod 41. The inner wall of the arc groove 3 is movably connected to the threaded rod 41. The outer wall of the threaded rod 41 is fixedly connected to a supporting plate 42. The outer wall of the threaded rod 41 is sleeved with a washer 43. The outer wall of the threaded rod 41 is threadedly connected to a hexagonal nut 44. The washer 43 is arranged between the hexagonal nut 44 and the main board 1. The outer wall of the support plate 42 is rotatably connected to a placing plate 45. The placing plate 45 is provided with a placing groove. A placing platform is provided through the placing groove for placing measuring equipment. The top of the placing plate 45 is fixedly connected to an adjusting plate 46, and a threaded through hole is provided on the adjusting plate 46.

[0025] In the present invention, the inner wall of the adjusting plate 46 is threadedly connected with an adjusting screw 47. By first adjusting the screw 47, the adjusting screw 47 is brought into contact with the surface of the support plate 42, so that the placement plate 45 and the support plate 42 are maintained at 90 degrees. A slide groove is provided on the support plate 42, and the slide groove is a through groove design. The inner wall of the support plate 42 is slidably connected with a sliding block 48. The sliding block 48 is a C-shaped design and is welded by an L-shaped plate and a square plate.

[0026] Furthermore, the inner wall of the connecting plate 2 is detachably connected to a connecting piece 5, the top of the connecting piece 5 is threadedly connected to a second hexagonal nut 6, a ring platform is provided on the connecting piece 5, and two groups of ring platforms are provided. The bottom of the connecting plate 2 is tightly attached to the top of the upper ring platform, and the bottom of the connecting piece 5 is plugged into a mounting plate 7, and the bottom of the connecting piece 5 is threadedly connected to a third hexagonal nut 8. A step groove is provided on the mounting plate 7, and the bottom of the lower ring platform is plugged into the inner wall of the step groove. The top of the mounting plate 7 is fixedly connected to a mounting block 9, which is a C-shaped design. A mounting through hole 10 is provided on the mounting block 9, and six groups of mounting through holes 10 are provided.

[0027] When in use, the mounting block 9 is conveniently installed on the tunnel pipe by fitting the bolt and nut tool through the mounting through hole 10. The connector 5 is inserted into the step groove on the mounting plate 7, and then the hexagonal nut 2 is tightened to complete the fixed connection between the connector 5 and the mounting plate 7.

[0028] By loosening the second hexagonal nut 6, the connecting plate 2 can be rotated on the connecting piece 5, thereby changing the angle between the connecting plate 2 and the main plate 1. By loosening the first hexagonal nut 44, the position of the threaded rod 41 can be moved on the arc groove 3, thereby driving the support plate 42 to move. At the same time, the angle of the support plate 42 can also be changed, so that the angle of the placement plate 45 can be changed.

[0029] In order to reduce the space occupied by the device, by loosening the adjusting screw 47, the adjusting screw 47 is separated from the surface of the support plate 42, the limiting state of the placement plate 45 is released, and the placement plate 45 can be rotated on the support plate 42. When the placement plate 45 is rotated to an angle parallel to the support plate 42, we can slide the sliding block 48 to move it above the adjustment plate 46. At this time, we rotate the adjusting screw 47 to make the surface of the adjusting screw 47 contact the surface of the sliding block 48, so that the sliding block 48 cannot slide in the through groove. At the same time, since the adjusting screw 47 is fixed, the angle of the placement plate 45 is limited, completing the storage work of the placement plate 45 and reducing the space occupied by the device.
