Description

Technical Field

[0001] This utility model relates to the field of tunnel shaft construction, specifically a tunnel shaft construction surveying device. Background Technology

[0002] Tunnel shaft surveying is a surveying method that transfers coordinates and elevations from the ground control network to the underground via shafts. In the construction of long tunnels, in order to increase the number of working faces and speed up the project, shafts are excavated at appropriate locations to divide the entire tunnel into several sections for segmented excavation. To ensure the correct completion of the tunnel, the coordinates and elevations from the ground control network must be transferred to the underground via shafts. This surveying work is called shaft connection surveying. The accuracy of directional transmission directly affects the precise completion of a tunnel. Transmitting the excavation direction also transmits coordinates underground. To facilitate the measurement of coordinates and elevation, a measuring device is required. The "Tunnel Shaft Construction Measuring Device" disclosed in application number "202320660353.9" represents an increasingly mature technology. This invention, through the design of a positioning frame, electric push rod, and level, allows the surveyor to observe the level and adjust the extension length of the electric push rod, ensuring that the four level bulbs at the corners remain horizontal. The positioning seat provides support, and the wear-resistant pad at its bottom provides anti-slip protection. The push rod positioning column also provides support, achieving a perfect angle. This allows the measuring instrument to be placed horizontally, enabling use in both horizontal and vertical orientations. The measuring device can be used simply by installing and adjusting the measuring end, making it more widely applicable, effectively improving horizontal accuracy, and suitable for different placement bases. However, this measuring device still has the following shortcomings during use: While the electric push rod and level bubble design facilitate the measurement of tunnel shaft coordinates and elevation using a measuring instrument, these structures alone are not suitable for simultaneous lateral and longitudinal measurements, thus affecting ease of use. Therefore, it is necessary to provide a measuring device that facilitates both lateral and longitudinal measurements and enhances practicality. Furthermore, the fixed size of this measuring device makes it unsuitable for shafts with different counterweight dimensions. Therefore, it is necessary to provide a measuring device that can be used with shafts of different sizes and enhances versatility. Utility Model Content

[0019] In one specific embodiment, the mounting groove 111 can enhance the installation stability of the hydraulic cylinder 105, and the support 112 can improve the rotational connection stability of the transmission gear 106, thereby improving the smoothness of the angle adjustment of the vertical instrument 109.

[0020] Please see Figure 2 and Figure 3 A linear guide rail 121 is fixedly connected to the upper end of the receiving plate 102, and a guide groove 122 is provided at the lower end of the toothed plate 104. The linear guide rail 121 is slidably connected inside the guide groove 122.

[0022] Please see Figure 2 and Figure 3 The end of the mounting tube 103 is provided with a fastening screw hole 131.

[0028] Please see Figure 4 One end of the electric telescopic shaft 201 is fixedly connected to a fastening bolt 221, which is threaded into the inside of the fastening bolt hole 131. The anti-slip strip 203 is made of rubber.

[0029] In one specific embodiment, the fastening bolt 221 is threaded into the fastening bolt hole 131 to enhance the stability of the electric telescopic shaft 201 installed inside the mounting tube 103 and to facilitate disassembly and assembly.

[0030] Working principle: In use, the extension and retraction of several electric telescopic shafts 201 are activated to support or retract the arc-shaped strip 202. This allows control over the surface of several anti-slip strips 203 and the installation of tunnel shafts of different sizes. The rubber anti-slip strips 203 significantly improve the friction and stability of the measuring device installed in the shaft, thereby enhancing the versatility of the measuring device. When performing horizontal and vertical measurement operations, the hydraulic cylinder 105 is activated to support or pull the toothed plate 104.
