Description

Technical Field

[0001] This utility model relates to the field of measurement standard connectors, specifically to a measurement standard connector for pre-embedded forced centering double base heightening on the arch surface. Background Technology

[0002] Tunnel traverse surveying is a technical means to ensure the accuracy of direction and position during tunnel construction. In tunnel traverse surveying, the use of pre-embedded forced centering plate double base heightening measurement standard connectors on the invert surface can improve the accuracy of traverse surveying, gyroscope measurement and point protection, while reducing the cost of point protection and re-surveying due to traverse damage.

[0003] The existing standard connector for pre-embedded forced centering double-base heightening measurement on the invert surface ensures the stability of the heightening connector during measurement through the design of the fixed screw joint. Although the above method can reduce the measurement error caused by instrument shaking after heightening, when using the heightening connector through the screw joint, the bottom end is only fixed by a single threaded post. When the terrain is uneven, the screw is easily stripped due to uneven force. At the same time, the method of fixing the top of the device only by inserting a post can easily cause the total station mounting plate to shift, and it is impossible to fix it separately, thus affecting the stability of the device.

Two extension plates are symmetrically installed on the two side walls of the total station mounting plate, and two extension plates are symmetrically arranged on the two side walls of the connecting plate. The top of the extension plates has a slot. The bottom end of the extension plate is connected to the slot of the extension plate through an insert plate. A threaded rod is provided in the middle of the bottom end of the insert plate, and a locking nut is installed at the bottom end of the threaded rod. A base plate is provided at the bottom end of the heightening base, and a centering plate is provided at the bottom end of the base plate. A threaded connecting column is fixed in the middle of the top end of the centering plate, and a rubber pad is provided around the top of the centering plate.

[0008] Furthermore, a column is installed at the center of the top of the heightening base, and a rubber compression pad is provided on the outer wall of the column. Four magnetic suction columns are fixed around the top of the heightening base, and a connecting plate is provided at the top of the heightening base. Limiting grooves are provided on both the connecting plate and the total station mounting plate, and four magnetic suction grooves are provided around the limiting grooves.

[0009] By adopting the above technical solution, the device ensures the stability of the heightened connector during measurement through the design of the fixed spiral opening, thereby reducing the measurement error caused by the shaking of the instrument after heightening.

[0010] Furthermore, the magnetic suction post corresponds one-to-one with the magnetic suction groove, the magnetic suction post is connected to the heightening seat screw, the insertion post is connected to the heightening seat screw, and the rubber extrusion pad is bonded to the insertion post.

[0011] By adopting the above technical solution, the design of the magnetic suction column and the insertion column can achieve a tight splicing between the connection plate and the total station mounting plate at any time, ensuring the stability of the top of the device when installing the total station.

[0012] Furthermore, both the magnetic suction groove and the limiting groove are formed on the connecting plate, and the centering plate is connected to the threaded connecting column by screws.

[0013] By adopting the above technical solutions, the design of the magnetic suction groove and the limiting groove can effectively prevent the top of the device from rotating and shifting. The design of the centering plate facilitates its burial and fixing, ensuring the stability of the bottom of the device.

[0014] Furthermore, the connecting plate is connected to the heightening seat screw, the extension plate is connected to the total station mounting plate screw, and the insert plate is connected to the extension plate screw.

[0015] By adopting the above technical solution, the design of the connecting plate enables the splicing of the total station mounting plate. The design of the extension plate one in conjunction with the extension plate two facilitates the alignment operation of the connecting plate and the total station mounting plate.

[0016] Furthermore, the second extension plate is screwed to the connecting disc, the slot is formed on the second extension plate, the threaded rod is screwed to the insert plate, and the locking nut is threaded to the threaded rod.

[0017] By adopting the above technical solution, the insert plate is inserted into the slot, and the design of the threaded rod and the locking nut realizes the fixation of the connecting plate and the total station mounting plate when connected, ensuring the stability of the device during use.

[0018] Furthermore, the base plate is connected to the heightening seat screw, the base plate is threadedly connected to the threaded connecting post, and the rubber pad is bonded to the centering plate.

[0019] By adopting the above technical solution, the design of the threaded connecting column facilitates the installation or disassembly of the device at any time.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the existing design of fixed screw threads for the pre-embedded forced centering double-base height measurement standard connector on the invert surface, which ensures the stability of the heightened connector during measurement, while reducing measurement errors caused by instrument shaking after heightening, the method of fixing the heightened connector at the bottom with only one threaded post during installation can lead to uneven screw force and stripping deviation on uneven terrain. Furthermore, fixing the top of the device with only a single insert post can easily cause displacement of the total station mounting plate, and it cannot be individually fixed, thus affecting the stability of the device. This invention addresses these issues by designing a threaded connecting post and a rubber pad. During the splicing of the centering plate and the base plate, the rubber pad makes close contact with the centering plate, allowing the base plate to easily and evenly distribute force on the centering plate, ensuring the support effect of the device. Simultaneously, when fixing the top of the connector, the extension plate one and extension plate two are spliced ​​together, and the locking nut secures the threaded rod, effectively ensuring a stable connection between the total station mounting plate and the connecting plate, and effectively guaranteeing the stability of the connecting plate's position.
