Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a total station bracket for shield tunneling surveying. Background Technology

[0002] To control the position and direction of the tunnel boring machine (TBM), surveying technology is indispensable during TBM construction, with total stations being commonly used in engineering projects. Total stations typically require a support bracket for fixation; however, existing brackets are simple in structure, and due to limitations, they cannot be placed horizontally when fixed to the tunnel wall. This prevents the total station from maintaining a horizontal position after being mounted, affecting its measurement accuracy. Therefore, a bracket that solves these problems is needed. Utility Model Content

[0003] To address the problem that existing brackets are simple in structure and, due to limitations, cannot be placed horizontally when fixed to the inner wall of the tunnel, thus preventing the total station from maintaining a horizontal position after being fixed to the bracket and affecting the total station's measurements, a total station bracket for shield tunneling surveying is invented.

[0004] The technical solution of this utility model is a total station bracket for shield tunneling surveying, including a support plate, wherein an adjustment plate is connected to one end of the support plate, a positioning plate is connected to the adjustment plate, a first fixing plate is rotatably connected to the positioning plate, a guide bar is connected to the lower part of the other end of the support plate, a sliding block is slidably connected to the guide bar, a support rod is rotatably connected to the sliding block, a second fixing plate is rotatably connected to the support rod, and a horizontal level and a vertical level are connected to the support plate.

[0005] Preferably, the positioning plate has a pair of adjustment holes, and the two ends of the adjustment plate have connection holes corresponding to the adjustment holes. Adjustment bolts are connected to the connection holes and the adjustment holes.

[0006] Preferably, a first hinge joint is connected to the positioning plate, and a second hinge joint is connected to the first fixing plate. The first hinge joint and the second hinge joint are connected by a first hinge shaft.

[0009] Preferably, the support rod includes a base rod and a telescopic rod. One end of the telescopic rod is slidably connected to the base rod. A positioning bolt is threaded onto the outer end face of the base rod near the telescopic rod. One end of the positioning bolt extends into the base rod, so that when the positioning bolt abuts against the telescopic rod, the telescopic rod is locked and positioned, preventing the telescopic rod from moving relative to the base rod, thereby adjusting the length of the entire support rod.

[0010] Preferably, a fifth hinge joint is connected to the end of the base rod away from the telescopic rod, and a sixth hinge joint is connected to the second fixing plate. The fifth hinge joint and the sixth hinge joint are connected by a third hinge shaft.

[0011] The following beneficial effects can be achieved by adopting the technical solution of this utility model: (1) The first fixed plate and the second fixed plate facilitate the fixing of the support plate and the support rod to the inner wall of the tunnel, thereby using the support plate and the support rod to support and connect the total station; (2) The first hinge joint, the second hinge joint and the first hinge shaft enable the positioning plate to rotate relative to the first fixed plate, thereby enabling the support plate to rotate vertically relative to the first fixed plate; (3) The longitudinal horizontal adjustment of the support plate is achieved by the adjusting plate, the positioning plate, the positioning bolt and the adjusting hole; (4) The guide strip, the sliding block, the base rod and the extension The telescopic rod and positioning bolts enable the adjustment of the horizontal level of the support plate by adjusting the length of the telescopic rod within the base rod, thereby ensuring that the total station connected to the support plate remains horizontal; (5) the third hinge joint, fourth hinge joint, second hinge shaft, fifth hinge joint, sixth hinge joint and third hinge shaft enable the adjustment of the angle between the support rod and the support plate, thereby enabling better adjustment of the horizontal state of the support plate; (6) the horizontal level and longitudinal level facilitate the detection of the horizontal state of the support plate; the technical solution of this utility model has a wide application prospect in the field of bracket technology.

[0017] This application discloses a total station bracket for shield tunneling surveying. (Refer to...) Figure 1 The system includes a support plate 8, which is used to connect a total station, thereby providing support for the total station. A horizontal level 21 and a vertical level 22 are detachably and fixedly connected to the support plate 8 by bolts, allowing the horizontal level 21 and the vertical level 22 to detect the horizontal state of the support plate 8.

[0018] Reference Figure 1 , Figure 2An adjusting plate 5 is welded to one end of the supporting plate 8, so that the adjusting plate 5 and the supporting plate 8 are connected together to form a whole. The adjusting plate 5 is connected to a positioning plate 4, so that the positioning plate 4 and the adjusting plate 5 are connected together to form a whole. The positioning plate 4 is rotatably connected to a first fixing plate 1, so that the positioning plate 4 and the first fixing plate 1 are connected together, thereby connecting the first fixing plate 1 and the supporting plate 8 together, and at the same time, the first fixing plate 1 is used to connect the supporting plate 8 to the inner wall of the tunnel.

[0019] Reference Figure 1 A first hinge joint 3 is welded to or detachably fixed to the positioning plate 4 via bolts, so that the first hinge joint 3 and the positioning plate 4 are connected together to form a whole. A second hinge joint 2 is welded to or detachably fixed to the first fixing plate 1 via bolts, so that the second hinge joint 2 and the first fixing plate 1 are connected together to form a whole. The first hinge joint 3 and the second hinge joint 2 are connected by a first hinge shaft, so that the first fixing plate 1 and the positioning plate 4 are rotatably connected together through the first hinge joint 3, the second hinge joint 2 and the first hinge shaft, thereby enabling the positioning plate 4 to be adjusted vertically relative to the first fixing plate 1.

[0020] Reference Figure 1 , Figure 2 The positioning plate 4 has a pair of arc-shaped adjustment holes 6. The two ends of the adjustment plate 5 have corresponding connection holes. Adjustment bolts 7 are connected to the connection holes and adjustment holes 6, so that the adjustment plate 5 and the positioning plate 4 are connected together to form a whole by adjusting bolts 7. At the same time, the adjustment bolts 7 can be used to make the adjustment plate 5 and the positioning plate 4 rotate relative to each other, thereby adjusting the position. In addition, the longitudinal tilt angle of the support plate 8 can be adjusted in conjunction with the longitudinal level 22, so that the support plate 8 can be kept horizontal in the longitudinal direction.

[0021] Reference Figure 1 A guide strip 9 is welded to the lower part of the other end of the support plate 8, connecting the guide strip 9 and the support plate 8 together to form a whole. A sliding block 11 is slidably connected to the guide strip 9, allowing the sliding block 11 to be slidably connected to the guide strip 9. Specifically, the guide strip 9 has a guide hole 10, and the sliding block 11 is threaded with several limiting screws 12. There are multiple limiting screws 12, which are slidably connected within the guide hole 10. This allows the sliding block 11 to be slidably connected to the guide strip 9 by the limiting screws 12 passing through the guide hole 10, and also limits the sliding block 11 to prevent it from detaching from the guide strip 9.

[0022] Reference Figure 1A support rod is rotatably connected to the sliding block 11, thereby connecting the support rod to the sliding block 11 and then to the support plate 8. Specifically, a third hinge joint 13 is welded to or detachably connected to the sliding block 11 via bolts, forming a single unit with the sliding block 11. A fourth hinge joint 14 is welded to or detachably fixed to the support rod via bolts, connecting one end of the support rod to the fourth hinge joint 14. The third hinge joint 13 and the fourth hinge joint 14 are connected via a second hinge shaft, connecting the support rod to the sliding block 11 to form a single unit. This allows the support rod to rotate vertically relative to the sliding block 11, while simultaneously creating a triangular structure between the support rod and the support plate 8, ensuring stable support of the total station by the entire bracket.

[0023] Reference Figure 1 The support rod includes a base rod 16 and a telescopic rod 15. One end of the telescopic rod 15 is slidably connected inside the base rod 16, allowing the length of the entire support rod to be adjusted by adjusting the length of the telescopic rod 15 within the base rod 16. The other end of the telescopic rod 15 outside the base rod 16 is welded to or detachably connected to a fourth hinge joint 14 via bolts, connecting the telescopic rod 15 and the fourth hinge joint 14 together to form a single unit, thus connecting the entire support rod to the sliding block 11. A positioning bolt 17 is threaded onto the outer end face of the base rod 16 near the end of the telescopic rod 15, with one end of the positioning bolt 17 extending into the base rod 16. This locking and positioning of the telescopic rod 15 when it comes into contact with the base rod 16 prevents the telescopic rod 15 from moving relative to the base rod 16, thereby adjusting the length of the entire support rod.

[0024] Reference Figure 1 The support rod is rotatably connected to a second fixing plate 20, which connects the second fixing plate 20 to the support rod, thereby connecting the support rod to the tunnel wall as a whole. Specifically, a fifth hinge joint 18 is welded to or detachably fixed to the end of the base rod 16 away from the telescopic rod 15, connecting the fifth hinge joint 18 to the base rod 16 as a whole. A sixth hinge joint 19 is welded to or detachably fixed to the second fixing plate 20, connecting the sixth hinge joint 19 to the second fixing plate 20 as a whole. The fifth hinge joint 18 and the sixth hinge joint 19 are connected by a third hinge shaft, connecting the support rod to the second fixing plate 20 as a whole, thereby allowing the support rod to rotate vertically relative to the second fixing plate 20.

[0025] In use, firstly, the first fixing plate 1 is fixed to the inner wall of the tunnel with expansion screws. Then, the adjusting plate 5 and the positioning plate 4 are adjusted with adjusting bolts 7. With the help of the longitudinal level 22, the longitudinal level of the support plate 8 is adjusted. Next, the second fixing plate 20 is fixed to the inner wall of the tunnel with expansion screws, so that the support rod, the support plate 8 and the inner wall of the tunnel form a triangular structure, so that the entire bracket can stably support the total station connected to the support plate 8. Then, the positioning bolts 17 are loosened and the length of the telescopic rod 15 within the base rod 16 is adjusted. With the help of the transverse level 21, the transverse level of the support plate 8 is adjusted. After the support plate 8 is transversely level, the positioning bolts 17 are tightened. Finally, the total station is fixed to the support plate 8 with bolts.

[0026] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
