Description

Technical Field

[0001] The present application relates to the technical field of shield tunnel construction measurement, and in particular to an adjustable hanging basket device for a shield tunnel measurement total station. Background Art

[0002] Shield tunnel construction technology is currently the most widely used construction technology for fully mechanized excavation of underground tunnels internationally. However, due to the relatively complex strata used for shield construction, the shield machine's posture data must be constantly monitored during the shield excavation process, and the pressure and excavation speed of each group of cylinders must be adjusted in a timely manner to keep its posture within the specification requirements. As the shield machine advances, the total station of the guidance system must also keep pace and transfer in the direction of excavation. Due to the small available space above the trolley, the large number of mechanical equipment, poor visibility, and the operation of the slag conveyor, the surveyors must choose a suitable location to install the hanging basket when transferring the total station. This requires ensuring a good visibility environment, facilitating measurement operations, and being quick and convenient to ensure that normal construction is not affected, and to quickly provide accurate positioning data for the shield machine's excavation.

[0003] During the tunneling process, the shield body of the shield machine will rotate at a certain angle, causing the formed segments to rotate at a certain angle as well. When the traditional total station basket is installed on the segments, its base cannot be leveled, resulting in a decrease in measurement accuracy. Utility Model Content

[0030] Example 1:

[0031] See also Figure 1 A shield tunnel measurement total station transfer adjustable hanging basket device, the shield tunnel measurement total station transfer adjustable hanging basket device comprising:

[0032] A first trapezoidal wedge plate 1 is arranged obliquely, and a connecting plate 2 is obliquely connected to the lower end thereof, and a second trapezoidal wedge plate 3 is obliquely arranged at the lower end of the connecting plate 2;

[0033] A fixing plate 4 is horizontally arranged on one side of the bottom of the connecting plate 2. A forced centering plate 5 is provided above the end of the fixing plate 4 away from the connecting plate 2. The forced centering plate 5 is fixed to the fixing plate 4 by three connecting bolts 6.

[0034] The upper and lower ends of the connecting bolt 6 are both threadedly connected with nuts, and the heights of the three positions of the forced centering plate 5 can be adjusted by rotating the nuts.

[0035] Specifically, the lower end of the first trapezoidal wedge plate 1 is fully welded to the upper end of the connecting plate 2, and the lower end of the connecting plate 2 is fully welded to the upper end of the second trapezoidal wedge plate 3. The connecting plate 2 is tilted to ensure that the connecting plate 2 fits the inner arc surface of the pipe segment. The end of the fixing plate 4 away from the connecting bolts 6 is fully welded to the bottom of the connecting plate 2. Three through holes are opened on the end of the fixing plate 4 away from the connecting plate 2 to allow the connecting bolts 6 to pass through. The through holes have a diameter of 16 mm. After the forced centering plate 5 is placed parallel to the top of the fixing plate 4, the two are connected by the connecting bolts 6. Then, nuts are inserted into the upper and lower ends of the connecting bolts 6 and tightened to fix the two.

[0036] When in use, the upper and lower nuts of the three connecting bolts 6 are rotated respectively to change their positions to adjust the heights of the three positions of the forced centering plate 5, thereby achieving the leveling of the forced centering plate 5, effectively avoiding the situation where the total station cannot be leveled due to the rotation of the pipe segment, thereby improving the accuracy of the measurement.

[0037] Finally, the finished hanging basket is transported to the construction site for installation testing. Appropriate adjustments can be made to inappropriate parts to ensure that the hanging basket can be accurately installed and put into use.

[0038] The present application provides a shield tunnel survey total station with an adjustable transfer basket device, which provides safety for the total station in the guidance system, improves the surveyor's work efficiency, and can be disassembled and reused repeatedly. The basket is highly stable, and after the total station is installed, it will not experience instrument bubble deviation caused by vibration from the tunneling equipment. It provides accurate attitude data for shield tunneling, ensuring the orderly progress of the entire construction process.

[0041] Specifically, the upper end of the connecting rod 7 is welded and fixed to the upper middle part of the side of the connecting plate 2, and the lower end of the connecting rod 7 is welded and fixed to the middle part of the side of the fixing plate 4. By setting the connecting rod 7, the structural strength of the device is enhanced, its stability is increased, and the load weight of the hanging basket is increased.

[0042] Optionally, there is an angle between the connecting plate 2 and the fixing plate 4, and the angle is 60°.

[0043] Specifically, the connecting plate 2 and the fixing plate 4 are cut in advance according to the dimensions of the design drawings and need to be welded on site to ensure that the connecting plate 2 fits the inner arc surface of the pipe segment. The fixing plate 4 is on a horizontal plane and can be removed after welding. In this embodiment, a 60° angle is formed between the connecting plate 2 and the fixing plate 4. The bottom of the connecting plate 2 and the fixing plate 4 are located on the same horizontal plane. In actual situations, the size of the angle formed by the two is not unique and can be adjusted according to actual conditions.

[0044] Optionally, the first trapezoidal wedge plate 1 is provided with screw holes matching the segment bolts, and the second trapezoidal wedge plate 3 is provided with half-waist openings matching the segment bolts.

[0045] Specifically, the first and second trapezoidal wedges 1 and 3 must be machined according to the bolt hole layout on the segment design drawings. After installation, they must be securely aligned with the segment bolt holes. The second trapezoidal wedge 3 features a half-waisted opening, allowing the hanging basket to be installed by simply loosening the segment bolts and nuts without removing all the bolts.

[0046] Optionally, the connecting plate 2 is a steel plate of 300×150×10 mm.

[0047] Specifically, the steel plate with a specification of 300×150×10 mm meets the usage requirements while ensuring a light structure.

[0051] Specifically, the forced centering plate 5 is processed and milled according to the design drawings. The hole position needs to correspond to the fixed plate 4 to ensure that the connecting bolt 6 can be vertically inserted into the hole. By adjusting the position of the upper and lower nuts of the forced centering plate 5, the flatness of the entire surface is ensured to meet the use requirements.
