Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a total station measurement and installation platform. Background Art

[0002] A total station is a measuring instrument integrating a rangefinder, a theodolite, data processing and recording, and is used for accurate angle and distance measurement. It is widely used in construction, civil engineering and topographic surveying.

[0003] The design of a subway tunnel may be affected by historical reasons, terrain restrictions or other external factors, resulting in the tunnel needing to be designed with many bends. In the measurement of a traditional subway shield tunnel with a diameter of less than 8 meters, the total station and the laser target of the guiding system are generally installed in the upper right. The space above is narrow and only one person can walk squatting. Moreover, there are many oil pipes above the shield machine. When the shield machine advances, the temperature of the oil pipes is extremely high, and the temperature in the upper space continuously remains above 40°C. When the shield machine is normally tunneling, due to the turning, the total station of the guiding system and the laser target are not visible to each other. At this time, a station change measurement is required.

[0004] As disclosed in the Chinese utility model patent (CN214040033U), a positioning device for a total station of a shield tunneling measurement guiding system is provided, which records: "Using the existing assembly bolts on the segment to fix the total station, there is no need to drill holes on the segment for fixation, which is convenient for installation and disassembly, without consuming other materials, and is energy-saving and environmentally friendly." It also records the technical problem: "The conventional method is to drill holes in the formed tunnel segment and drive expansion bolts to fix the forced centering plate, which consumes materials and labor, and damages the surface structure of the segment."

[0005] To sum up, it can be seen that in the prior art, the existing assembly bolts on the segment are used to fix the total station. However, this method has the following technical problems: In the measurement of a subway shield tunnel, the environment for the operator to move is small and the temperature is high, which is not convenient for the operator to work in this space for a long time. Therefore, the number of station changes should be reduced to shorten the working time of the operator. However, the above device does not have relevant structural design. For this reason, this application proposes a total station measurement and installation platform to provide a new technical solution to solve the technical problems mentioned in the above patent.

By symmetrically arranging two fixed receiving plates on the left and right sides of the receiving rod, the operator can install the total station on the receiving plate close to the segment or the receiving plate on the side close to the tunnel center line. Then, the position of the total station installation can be adjusted according to the measurement scenario. When the tunnel turns left, the total station is installed on the side close to the segment, and when the tunnel turns right, it is installed on the side close to the tunnel center line, increasing the through-view distance between the total station and the laser target, thereby reducing the number of station changes. Moreover, the method of fixing the total station with centering bolts is relatively simple, facilitating the replacement and installation of the total station and improving the working efficiency of the operator.

[0007] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0029] As described in the background art, however, in the measurement of subway shield tunnels, the environment for the operator to move is small and the temperature is high, which is not convenient for the operator to work in this space for a long time. Therefore, the number of station changes should be reduced to shorten the working time of the operator, and the above device does not have relevant structural designs.

[0030] To solve this technical problem, the present utility model provides a total station measurement and installation platform, which is applied to the installation of total stations in subway shield tunnel measurement.

[0031] Specifically, please refer to Figures 1 - 3 , the total station measurement and installation platform specifically includes:

[0032] The first segment 1 and the second segment 2, the inner walls of the first segment 1 and the second segment 2 are slidably connected with an installation arc rod 3, one end of the installation arc rod 3 is fixedly connected with a stop block 4, the outer wall of the installation arc rod 3 is threadedly connected with an internal thread block 5, a support mechanism 6 is arranged on the installation arc rod 3, and an installation mechanism 7 is arranged on the support mechanism 6;

[0033] The support mechanism 6 includes a support frame 8, a receiving rod 11, an installation component, a support component, and a stabilizing component. The outer wall of the support frame 8 is fixedly connected with a receiving rod 11.

Then, the position of the total station installation can be adjusted according to the measurement scenario to be measured. When the tunnel turns left, the total station is installed on the side close to the segment, and when the tunnel turns right, it is installed on the side close to the tunnel center line, increasing the clear vision distance between the total station and the laser target, thereby reducing the number of station changes. Moreover, the method of fixing the total station by the centering bolt 15 is relatively simple, facilitating the replacement and installation of the total station, and improving the working efficiency of the operator.

[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0036] Embodiment 1:

[0037] Please refer to Figures 3 - 4 , a total station measurement installation platform, which includes:

[0038] The installation component includes a first installation piece 9. The outer wall of the support frame 8 is fixedly connected with the first installation piece 9. A second installation piece 10 is fixedly connected to the side of the support frame 8 away from the first installation piece 9. The first installation piece 9 is sleeved outside the installation arc rod 3, the second installation piece 10 is closely attached to the outer wall of the installation arc rod 3, and a through hole for passing through the installation arc rod 3 is provided on the first installation piece 9.

[0039] The support component includes a stabilizing rod 13. The outer wall of the support frame 8 is fixedly connected with the stabilizing rod 13. The end of the stabilizing rod 13 away from the support frame 8 is closely attached to the outer walls of the first segment 1 and the second segment 2. The stabilizing rod 13 can prevent the first installation piece 9 and the second installation piece 10 from rotating excessively outside the installation arc rod 3 after the device is installed, resulting in the situation where the receiving rod 11 tilts.

[0040] The stabilizing component includes a strengthening rod 12. The front and rear sides of the receiving rod 11 are respectively fixedly connected with a strengthening rod 12. The ends of the two strengthening rods 12 away from the receiving rod 11 are both fixedly connected to the outer wall of the support frame 8.

[0041] Through the above structural design, when installing the device, only need to unscrew the internal thread block 5, and draw out the installation arc rod 3 five millimeters to one centimeter in the direction of the stop block 4. Then, the first installation piece 9 can be sleeved on the installation arc rod 3, and the second installation piece 10 can be hooked on the installation arc rod 3. Then, screw on the internal thread block 5 to complete the fixation of the device. At the same time, relying on the stable rod 13 to abut against the first segment 1 and the second segment 2, the receiving rod 11 can be kept horizontal.

[0042] Embodiment 2:

[0043] The total station measurement installation platform provided in Embodiment 1 is further optimized. Specifically, as Figures 4 - 5 shown, the installation mechanism 7 includes a receiving plate 14. Two receiving plates 14 are fixedly connected to the outer wall of the receiving rod 11. The two receiving plates 14 are arranged symmetrically left and right. The two receiving plates 14 are used to receive the total station.

[0044] The installation mechanism 7 further includes centering bolts 15. Centering bolts 15 are respectively fixedly connected to the tops of the two receiving plates 14 and located at the center. The total station can be screwed onto the centering bolts 15 for fixation. This process is the same as the principle of installing the total station in cooperation with the connecting bolts in the prior art in the background technology, so no more details will be described.

[0045] Through the above structural design, adjust the installation position of the total station according to the measurement scenario. When the tunnel turns left, install the total station on the receiving plate 14 on the side of the segment. When the tunnel turns right, install it on the receiving plate 14 on the side close to the tunnel center line. After determining the receiving plate 14 to be installed, then place the base of the total station on the receiving plate 14 through the centering bolts 15.
