Description

Technical Field

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

[0002] In shield tunneling, total stations play a crucial role.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Most existing total station installation devices adopt a fixed support structure. For example, application number CN202322619052.4 discloses a shield tunnel total station installation device, which achieves height adjustment by setting a side column structure with connection holes, thereby leveling the mounting plate and the total station on the mounting plate.

[0005] However, the following technical problems exist: First, the height adjustment method using discrete connecting holes has limited accuracy. The spacing between the connecting holes determines the minimum height change for each adjustment. If the actual required leveling height change falls within the spacing between two connecting holes, precise leveling cannot be achieved, resulting in a slight tilt of the total station after installation, affecting measurement accuracy. Second, each adjustment requires re-fixing the connecting parts, increasing the complexity and time cost of the operation. Third, this rigid connection structure is difficult to adapt to the curvature changes of the tunnel lining surface, easily causing the mounting base to tilt. If the mounting base tilts too much, the total station's leveling tilt angle is limited, making precise leveling impossible and affecting the measurement accuracy and performance of the total station in tunnel construction, failing to meet the requirements of current tunnel shield tunneling methods.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0019] This invention effectively avoids the technical problems of defects in the design of total station installation devices, low adjustment accuracy, and cumbersome and complicated operation that exist in the prior art.

[0020] This utility model provides a total station installation device for shield tunneling construction, including a first mounting column, a second mounting column, a third mounting column, a leveling drive structure, and a mounting base plate.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-2 As shown, the present invention provides an installation device for a total station 11 used in shield tunneling, comprising a first mounting column 1, a second mounting column 2, a third mounting column 3, a leveling drive structure 4, and a mounting base plate 5. The mounting base plate 5 is used to mount the total station 11. The first mounting column 1, the second mounting column 2, and the third mounting column 3 are arranged in a triangle and extend upwards at an angle away from the mounting base plate 5. The upper end of the first mounting column 1 is connected to the tunnel segment, and the lower end of the first mounting column 1 is connected to the mounting base plate 5 via the leveling drive structure 4. The upper end of the second mounting column 2 is rotatably connected to the tunnel segment, and the lower end of the second mounting column 2 is connected to the mounting base plate 5. The upper end of the third mounting column 3 is connected to the tunnel segment, and the lower end of the third mounting column 3 is connected to the mounting base plate 5.

[0029] In existing technologies, the installation accuracy of the total station 11 during shield tunnel construction directly affects the quality of engineering surveying. Traditional installation devices use a side column structure with insertion holes to achieve height adjustment. The spacing between the connection holes determines the minimum height change for each adjustment, resulting in insufficient leveling accuracy.

[0030] To address the aforementioned problems and the limitation of discrete hole position adjustment accuracy, this invention replaces the mechanical insertion structure with a continuous linear leveling drive structure 4. By controlling the leveling drive structure 4, the relative positional change between the first mounting post 1 and the mounting base 5 can be precisely adjusted. The upper end of the second mounting post 2 is rotatably connected to the tube segment, and the upper end of the third mounting post 3 is also connected to the tube segment, enabling the mounting device to adaptively adjust during leveling. Furthermore, the first mounting post 1, the second mounting post 2, and the third mounting post 3 are arranged in a triangle. Due to the stability of the triangular structure, it provides a stable support frame for the mounting base 5, allowing it to maintain a relatively stable state during leveling, thus improving structural stability and reliability. Through the synergistic effect of these components, this invention can quickly and accurately adjust the levelness of the mounting base 5, achieving precise leveling. Compared to existing technologies, this invention significantly improves leveling accuracy while simplifying the operation process and reducing operational difficulty.

[0031] Among them, the first mounting post 1, the second mounting post 2 and the third mounting post 3 extend upward at an angle, that is, each mounting post forms an angle with the vertical direction.

[0032] As an optional implementation, the upper end of the second mounting post 2 is connected to the tube segment via a rotating connection assembly. The rotating connection assembly includes a first connecting ring 6 and a second connecting ring 7 rotatably connected to the first connecting ring 6. The first connecting ring 6 is detachably connected to the tube segment, and the second connecting ring 7 is welded to the upper end of the second mounting post 2.

[0033] Furthermore, the first connecting ring 6 has an annular hole 601, and the second connecting ring 7 passes through the annular hole 601 of the first connecting ring 6 and the two are rotatably connected.

[0034] After the first connecting ring 6 is connected to the tube segment, it forms a fixed reference point. The second connecting ring 7 can rotate within a certain range relative to the first connecting ring 6. When the mounting base plate 5 tilts due to the leveling drive structure 4, the second mounting post 2 is driven by the displacement of the mounting base plate 5, and the rotation of the second connecting ring 7 relative to the first connecting ring 6 automatically adapts to the change in the tilt angle of the mounting base plate 5.

[0035] As an optional implementation, the mounting base plate 5 is a square plate structure and has a first side 501, a second side 502 and a third side 503 connected in sequence. The first mounting post 1 is located in the middle of the first side 501, the second mounting post 2 is located at the end of the second side 502 near the third side 503, and the third mounting post 3 is located at the end of the third side 503 away from the second side 502.

[0036] This configuration optimizes the spatial distribution of the support points on the mounting base plate 5 and improves leveling stability through asymmetrical support point settings.

[0037] As an optional implementation, an L-shaped connecting plate 9, adapted to the slot of the tube segment, is welded to the upper end of the first mounting post 1, the upper end of the third mounting post 3, and the upper end of the first connecting ring 6. The connecting plate 9 has threaded holes 901 adapted to the tube segment bolts, which pass through the threaded holes 901 to connect with the slot of the tube segment. The lower ends of the second mounting post 2 and the third mounting post 3 are respectively welded to the mounting base plate 5.

[0038] As an optional implementation, the axis of the leveling drive structure 4 coincides with the axis of the first mounting post 1, the fixed end of the leveling drive structure 4 is connected to the first mounting post 1, and the movable end of the leveling drive structure 4 is rotatably connected to the first side surface 501.

[0039] Furthermore, the movable end of the leveling drive structure 4 is rotatably connected to the first side surface 501 via the hinge structure 8.

[0040] As an optional implementation, the leveling drive structure 4 includes an electric push rod, hydraulic cylinder or pneumatic cylinder in the prior art, as long as it is a power device in the prior art that can output linear displacement.

[0041] As an optional implementation, the first mounting post 1, the second mounting post 2, and the third mounting post 3 are all hollow square tubes.

[0042] This design reduces the overall weight of the device while ensuring its structural strength.

[0043] As an optional implementation, the mounting base 5 is provided with a plurality of mounting holes 504 for connecting to the base of the total station 11.

[0044] Furthermore, the mounting hole 504 is matched with the size of the fixing bolts on the base of the total station 11.

[0045] When the total station 11 needs to be installed, its base is aligned with the corresponding mounting hole 504 by fixing bolts, and the connection between the two is completed by using bolts to pass through the corresponding mounting hole 504.

[0046] As an optional implementation, it also includes a horizontal tilt sensor 10 and a control system. The horizontal tilt sensor 10 is disposed on the mounting base plate 5, and the leveling drive structure 4 and the horizontal tilt sensor 10 are electrically connected to the control system.

[0047] Furthermore, the horizontal tilt sensor 10 is positioned close to the leveling drive structure 4 to detect the horizontal status of the mounting base plate 5 in real time.

[0048] When the horizontal tilt sensor 10 detects that the mounting base plate 5 is tilted, the control system drives the leveling drive structure 4 to extend and retract, causing the relative position of the first mounting post 1 and the mounting base plate 5 to change. This causes the mounting base plate 5 to adjust its three-dimensional spatial posture around the rotation connection point of the second mounting post 2 until the horizontal sensor reports that the tilt angle of the mounting base plate 5 meets the preset accuracy requirements.

[0049] It should be noted that the specific circuit connections between the leveling drive structure 4 and the horizontal tilt sensor 10 and the control system adopt existing technology, which will not be elaborated here.
