[0027] like Figure 1 As shown, the utility model provides a high-precision detachable settlement observation device, comprising:

[0028] A buckle assembly, comprising a fixed buckle 1 and a movable buckle 2, both of which are arc-shaped buckle plate structures with inner arc surfaces arranged opposite to each other, one end of the movable buckle 2 is hinged to one end of the fixed buckle 1; a locking member, one end of which is hinged to the other end of the fixed buckle 1, and the other end of the locking member is detachably connected to the other end of the movable buckle 2, and in the connected state, the locking member is configured to adjust the rotation angle of the movable buckle 2;

[0029] The movable frame includes a base 41, which is arranged on the outside of the fixing fastener 1 and is rotatably connected to the fixing fastener 1 through a first rotating mechanism, and the axis of the first rotating mechanism and the fixing fastener 1 are perpendicular to each other; a support frame 42, which is fixedly supported on the base 41 and extends in a direction away from the buckle assembly; and a mounting seat 43, which is arranged on the side wall of the support frame 42;

[0030] The measuring prism 6 is rotatably connected to the mounting seat 43 via a second rotating mechanism, and the axes of the second rotating mechanism and the first rotating mechanism are perpendicular to each other.

[0031] In the above technical scheme, suitable monitoring points are selected according to the layout of the full-hall bracket. The high-precision detachable settlement observation device corresponds one-to-one to the full-hall bracket (monitoring point) to be monitored. A single settlement observation device can be installed on the horizontal rod or other rod of the corresponding full-hall bracket through a snap-on assembly. In actual construction, a total station is installed in a suitable position outside the full-hall bracket (construction area), and the settlement of multiple monitoring points can be monitored in real time through prism reflection. Among them, the snap-fit ​​assembly has two connection states. In the non-locked state, the adjacent ends of the locking member and the movable fastener 2 are not fixedly connected. At this time, the fixed fastener 1 and the movable fastener 2 can rotate freely relative to each other. Since the locking member and the movable fastener 2 can be fixedly connected when they are relatively rotated to different angles, the connection position of the locking member and the end of the movable fastener 2 is adjustable. In the locked state, the fixed fastener 1 and the movable fastener 2 are relatively rotated to a suitable position, and the locking member adaptively rotates to a position abutting the end of the movable fastener 2 and then is locked (that is, fixedly connected to the end of the movable fastener 2). At this time, the inner arc surface of the fixed fastener 1, the inner arc surface of the movable fastener 2 and the inner side wall of the locking member form a closed loop. When installing the settlement observation device, first place the buckle assembly in the non-locking state at the monitoring point, so that the inner arc surface of the fixed fastener 1 abuts against the outer arc surface of the rod of the corresponding full-height bracket, and then rotate the movable fastener 2 in the direction close to the locking member until the inner arc surface of the movable fastener 2 also abuts against the outer arc surface of the above-mentioned rod (cannot continue to rotate), and finally rotate the locking member to press the end of the movable fastener 2 and fix it with it. The buckle assembly enters the locking state, and the rod is adaptively pressed and fixed by the closed loop formed by the fixed fastener 1, the movable fastener 2 and the locking member. This installation structure allows the buckle assembly to adapt to rods of different diameters within a certain range and quickly dock and install with them. The installation direction of the buckle assembly on the rod can be selected according to the full-height bracket structure, and it can be installed without affecting normal construction and ensuring observability.

[0032] After the buckle assembly is installed, the movable frame and the measuring prism 6 are stably fixed at the corresponding monitoring point. Since the axis of the first rotating mechanism and the fixed fastener 1 are perpendicular to each other, and the axis of the second rotating mechanism and the first rotating mechanism are perpendicular to each other, the first rotating mechanism and the second rotating mechanism can realize full-range adjustment of the direction of the reflecting surface of the measuring prism 6 so that it is fully aligned with the detection direction of the total station to ensure the accuracy and reliability of the monitoring results. Here, the axis of the fixed fastener refers to the axis of the complete circle / complete cylindrical surface where the inner arc surface contour of the fixed fastener is located, that is, a straight line passing through the arc center of the fixed fastener 1 and parallel to the inner arc surface of the fixed fastener 1. Specifically, in this embodiment, according to Figure 1In the direction shown, the buckle assembly is installed on the horizontal rod (the rod is set in the horizontal and forward direction), and the movable frame and the measuring prism 6 are located directly above the buckle assembly. After the buckle assembly is locked, the movable frame can drive the measuring prism 6 to rotate left and right under the action of the first rotating mechanism, and the measuring prism 6 can be turned up and down under the action of the second rotating mechanism. Therefore, no matter where the total station is set at any position / height at the rear, the reflection surface of the measuring prism can be rotated to the direction facing the total station lens through the cooperation of the first rotating mechanism and the second rotating mechanism. The installation direction of the high-precision detachable settlement observation device is not limited to the above-mentioned embodiment. According to the full-chamber bracket structure, there are also application forms such as the movable frame is set downward and the buckle assembly is installed on the vertical pole. With the cooperation of the rotating mechanism, the measuring prism can adapt well to different installation forms and smoothly implement settlement monitoring. The first and second rotating mechanisms can exchange information with the control equipment (terminal) outside the construction area (full-chamber bracket) in a wired / wireless manner. In addition, the center of the reflective surface of the measuring prism 6 is located at the intersection of the axes of the first rotating mechanism and the second rotating mechanism. Therefore, during the rotation process, the measuring prism 6 always rotates / flips in place around the center point, which is beneficial to ensure the stability of the prism reflective surface during adjustment and reduce measurement errors.

[0033] The high-precision detachable settlement observation device of the present invention has a simple structure and is easy to operate. The settlement observation device and the full-chamber bracket can be quickly disassembled and assembled through the snap-fit ​​assembly, and the multi-point hinged fasteners and adjustable locking structure of the snap-fit ​​assembly can well adapt to rods of different diameters, and has strong applicability. At the same time, the full-angle adjustment of the measuring prism reflection surface is realized through the two-way rotating mechanism, and the rotation angle of the rotating mechanism can be remotely controlled by the control terminal. In actual measurement, the direct contact between the measurement personnel and the bracket and the corresponding workload are greatly reduced, and the measurement efficiency is effectively improved. In the measurement process, the personnel do not need to repeatedly enter the full-chamber bracket to adjust the device, which reduces the safety risks in the measurement and ensures the accuracy of the measurement results.

[0034] In another technical solution, in the high-precision detachable settlement observation device, the middle part of the outer arc surface of the fixed fastener 1 protrudes outward to form a tangential plane, and the first rotating mechanism is arranged between the tangential plane and the base 41; the two ends of the fixed fastener 1 extend outward to form a hinge part, and the movable fastener 2 and the locking part are respectively hinged to the corresponding hinge part through the hinge shaft 11, and the hinge shaft 11 is parallel to the axis of the fixed fastener 1. Among them, the tangential plane is parallel to the tangent of the midpoint of the inner / outer arc surface of the fixed fastener 1, which not only provides a flat installation surface for the base 41 and the first rotating mechanism, but also helps to ensure the structural rationality and support stability of the overall settlement observation device. The hinged portion is configured as a U-shaped groove opening outward, and the ends of the movable fastener 2 and the locking member are respectively fitted into the corresponding U-shaped grooves and are rotatably connected to the U-shaped groove through the hinge shaft 11. According to the setting direction of the hinge shaft 11, the movable fastener 2 and the locking member both rotate on a plane perpendicular to the axis of the fixed fastener 1. Therefore, the rotation planes of the movable fastener 2, the first rotating mechanism, and the second rotating mechanism are perpendicular to each other, thereby maximizing the installation flexibility of the settlement observation device, enabling it to adapt to settlement observation needs under different conditions, and can be reused between different projects, which is beneficial to controlling construction monitoring costs.

[0035] In another technical solution, in the high-precision detachable settlement observation device, the arc center angle of the fixed fastener 1 is less than 150°, and the arc center angle of the movable fastener 2 is less than 150°. Thus, it is ensured that the fixed fastener 1, the movable fastener 2 and the locking member of the buckle assembly can stably form a three-stage closed loop structure in the locked state, and at the same time, the diameter range of the rod applicable to the installation of the buckle assembly is expanded, thereby improving the practicality of the device.

[0036] In another technical solution, in the high-precision detachable settlement observation device, the end of the movable fastener 2 away from the fixed fastener 1 is provided with a U-shaped slot 21 opening outward;

[0037] The locking member includes a screw rod 31, one end of which is hinged to the end of the fixing fastener 1; a washer 32, which is sleeved on the screw rod 31; a nut 33, which is sleeved on the screw rod 31 and threadedly connected therewith, and the nut 33 is located on the side of the washer 32 away from the fixing fastener 1;

[0038] In the locked state (of the buckle assembly), the outer end of the screw rod 31 fits into the U-shaped slot 21 , and the gasket 32 ​​and the nut press the U-shaped slot 21 from the outside to the inside.

[0039] In the above technical solution, the end of the movable fastener 2 (U-shaped slot 21) and the locking member (screw 31) can be locked at any position within the length range by cooperating with the screw 31 and the nut, so that after the movable fastener 2 is rotated to (any) appropriate angle relative to the fixed fastener 1, the locking member can be adaptively rotated to the corresponding position and connected to the outer end of the movable fastener 2 to fix its rotation angle / position. Specifically, the fixed fastener 1 and the movable fastener 2 are rotated in a non-locked state so that their inner arc surfaces are respectively pressed against the outer side wall of the monitoring point (rod), and then the positions of the two fasteners are kept stationary, and the locking member is rotated (the gasket 32 ​​and the nut 33 are taken out in advance or moved to the outer end of the screw 31) so that the outer end of the screw 31 is inserted into the U-shaped slot 21 and abuts against the outer side wall of the rod (cannot continue to rotate), and finally the gasket 32 ​​and the nut are inserted from the outer end to the inner end of the (screw 31) and locked, so that the adaptive locking of the buckle assembly to the rod is completed. After the settlement observation is completed, the settlement observation device can be removed from the monitoring point by simply unscrewing the nut in the reverse direction to disengage the locking member from the movable fastener 2. Figure 1 As shown, the nut 33 includes a hexagonal nut arranged in an inner layer (adjacent to the gasket 32) and a butterfly nut arranged in an outer layer (adjacent to the hexagonal nut), and double-layer locking effectively ensures the stability of the locking structure.

[0040] In another technical solution, the high-precision detachable settlement observation device, the base 41 is a crossbar parallel to the tangential plane, the support frame 42 is a vertical pole vertically arranged at the end of the crossbar, the mounting seat 43 is located on the inner wall of the vertical pole, and the measuring prism 6 is located directly above the crossbar. In the above technical solution, the movable frame is configured as an L-shaped structure, the bottom of the crossbar is connected to the buckle assembly, and the mounting frame is arranged on the inner wall of the vertical pole. This arrangement structure is reasonable, which is conducive to ensuring the force stability of the overall settlement observation device, and the measuring prism is located just above the crossbar after installation, which is convenient for aligning the center of the reflection surface of the measuring prism 6 with the arc center of the fixing fastener 1 through structural design, thereby reducing the measurement error.

[0041] In another technical solution, the high-precision detachable settlement observation device is provided with a linear guide rail (not shown in the figure) on the inner side wall of the support frame 42 along the length direction, and the mounting seat 43 is fixedly connected to the slider on the linear guide rail. In the above technical solution, the position of the mounting seat 43 on the support frame 42 can be adjusted in real time according to the monitoring needs. With the cooperation of the first and second rotating mechanisms, the flexibility of setting the azimuth of the measuring prism after the installation of the buckle assembly is further improved, avoiding the situation where the settlement observation cannot be carried out smoothly due to line of sight blocking or other unexpected factors. Among them, the linear guide rail is electrically connected to the control terminal located outside the construction area, and the control terminal is located outside the full-chamber bracket and can be set close to the total station, so that the construction personnel can adjust the setting height of the mounting seat (i.e., the spacing from the crossbar) according to the actual construction situation. During the adjustment process, the construction personnel do not need to enter the full-chamber bracket, which further improves the measurement efficiency and ensures the construction safety.

[0042] In another technical solution, the high-precision detachable settlement observation device, the first rotating mechanism and the second rotating mechanism each include a rotating motor and a controller, the controller is electrically connected to a control terminal located outside the construction area, and the controllers of the first and second rotating mechanisms can be integrated into one, the controller can collect the working signals of each rotating motor and transmit them remotely to the control terminal, and can also receive control signals from the control terminal and control the operation (rotation) of the rotating motor. The surveying personnel can remotely control and confirm the orientation state of the current measuring prism reflective surface through the control terminal. Specifically, the second rotating mechanism is fixed inside the mounting seat 43. In addition to being used to install the measuring prism 6, the mounting seat 43 can also be regarded as a protective shell of the second rotating mechanism, which is beneficial to prevent impurities from entering and affecting the normal operation of the rotating mechanism; similarly, the first rotating mechanism can also be protected by an outer shell during actual installation. In this embodiment (with Figure 1 The first rotating mechanism is fixedly mounted on the tangential plane of the fixing fastener 1, and the motor shaft of the rotating motor of the first rotating mechanism extends upward and is fixedly connected to the bottom center of the base 41. Thus, the movable frame can drive the measuring prism to rotate as a whole in the horizontal direction (left and right) by controlling the working state of the first rotating mechanism; the motor shaft of the rotating motor of the second rotating mechanism extends outward and is fixedly connected to the measuring prism. The extension line of the axis of the above-mentioned motor shaft passes through the axis center of the measuring prism 6 and is perpendicular to the axis of the measuring prism 6. Thus, the measuring prism can be rotated in the vertical direction (flipped up and down) by controlling the working state of the second rotating mechanism.

[0043] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
