Description

Technical Field

[0001] This utility model relates to the field of geological survey and mapping, specifically to an auxiliary mechanism for tilt measurement in surveying engineering. Background Technology

[0002] In geological surveys and mapping, workers often need to collect data, analyze samples, and draw maps under complex and diverse terrain and environmental conditions, requiring the use of various measuring tools (such as geological compasses, surveying benchmarks, or geodetic surveying devices). For example, a combined geological compass disclosed in application number 202111199413.3 includes a compass base and a tripod. A handle is detachably mounted on the front of the compass base, and a folding member is hinged to the end of the handle away from the compass base. The folding member swings to a vertical position, while the extension swings to a horizontal position parallel to the compass base. Then, it swings outwards towards the overhead plates, causing the two overhead plates to unfold below the compass base. Finally, the overhead plates are fitted onto the threaded support rod to achieve the geological compass's positioning, avoiding the impact of uneven rock surfaces or soil-rich areas on the survey. However, the steps involved in measuring parameters rely on the subjective experience of the measurer (such as judging whether the compass, the surveying target surface is vertical, and whether the bubble of the level is centered), which leads to many deviations in the measurement results. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an auxiliary mechanism for tilt measurement in surveying engineering. This tilt measurement auxiliary mechanism is used in conjunction with a geological compass, surveying benchmark, or geodetic surveying device. It can automatically achieve horizontal and vertical leveling, eliminating the need for manual operation by the user when measuring the tilt angle and eliminating the need for subjective adjustment of the compass, thereby reducing the workload of measurement and improving measurement accuracy.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An auxiliary mechanism for tilt measurement in surveying engineering includes a mounting base for mounting surveying tools and a load-bearing base. The load-bearing base is connected to the mounting base via a hollow telescopic link. A plumb bob is located inside the hollow cavity of the telescopic link on the bottom side of the mounting base facing the load-bearing base. A first transmitter is located at the bottom of the plumb bob. A first detector is located at the center of the load-bearing base to detect the displacement of the mounting base and the tilt of the telescopic link. At least three sets of pressure sensors are evenly distributed in the hollow cavity of the telescopic link and relative to the periphery of the plumb bob to assist in detecting the balance of the device.

[0006] The load-bearing base has a first rigid support rod, a second rigid support rod, and a third rigid support rod facing the ground at its bottom. A second transmitter is provided on the first rigid support rod, and a second detector is provided on the second and third rigid support rods corresponding to the second transmitter positions to detect the tilt of the load-bearing base. The load-bearing base is provided with two sets of drive mechanisms for moving the second and third rigid support rods relative to the first rigid support rod, so as to make adjustments when the mounting base is detected to be tilted relative to the load-bearing base.

[0007] Preferably, the hammer is suspended 5-10cm below the mounting base by a rope.

[0008] Preferably, the first rigid support rod is a hollow rod, wherein a first spike and a first fixing member are provided in the cavity. The first spike moves in extension and retraction relative to the first rigid support rod by a spring. When the first spike retracts into the hollow cavity, the first fixing member locks the first spike in place. When the first fixing member is released, the first spike pierces into the ground under the action of the spring force.

[0009] Preferably, both the second rigid support rod and the third rigid support rod are hollow rods, wherein a second rigid spike and an electric telescopic mechanism are distributed in the cavity. The electric telescopic mechanism drives the second rigid spike to telescopically move relative to the second rigid support rod or the third rigid support rod, so as to control the height of the second rigid support rod or the third rigid support rod respectively.

[0010] Preferably, each of the drive mechanisms includes a drive motor, a drive gear, and a driven gear located inside the load-bearing base. The output shaft of the drive motor is connected to the drive gear, and the drive gear meshes with the driven gear. The driven gear is respectively connected to the second rigid support rod or the third rigid support rod to drive the second rigid support rod or the third rigid support rod to move.

[0011] Preferably, the bottom surface of the load-bearing base is provided with an arc-shaped track hole for the movement of the second rigid support rod or the third rigid support rod, so as to limit the movement direction of the second rigid support rod or the third rigid support rod.

[0012] Preferably, the telescopic linkage includes a main rod connected to the load-bearing base, a support rod connected to the mounting base, and several sets of connecting rods located between the main rod and the support rod. The main rod and the connecting rod adjacent to the main rod, the adjacent connecting rod, the connecting rod adjacent to the support rod, and the support rod are interlocked and fixed by elastic fasteners to adjust the height of the mounting base.

[0013] Preferably, the bottom of the load-bearing base is provided with receiving grooves for respectively accommodating the first rigid support rod, the second rigid support rod, or the third rigid support rod. The first rigid support rod, the second rigid support rod, and the third rigid support rod rotate relative to the load-bearing base and are stored in the receiving grooves to reduce the floor space of the device when not in use.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model's tilt angle measurement auxiliary mechanism is used in conjunction with a geological compass, surveying benchmark, or geodetic surveying device. It can automatically achieve horizontal and vertical leveling, eliminating the need for manual operation by the user when measuring tilt angles and eliminating the need for subjective adjustment of the compass. This reduces the workload of measurement and improves measurement accuracy, playing a positive role in improving geological work. Attached Figure Description

Detailed Implementation

[0021] Example 1: A preferred embodiment of this utility model provides an auxiliary mechanism for tilt measurement in surveying engineering, including a mounting base 1 for mounting surveying tools and a load-bearing base 2. The load-bearing base 2 is connected to the mounting base 1 through a hollow telescopic connecting rod 3. A plumb bob 4 is provided on the bottom side of the mounting base 1 facing the load-bearing base 2, located in the hollow cavity of the telescopic connecting rod 3. The plumb bob 4 is suspended 5-10cm below the mounting base 1 by a rope. A first transmitter 5 is provided at the bottom of the plumb bob 4. A first detector 6 is provided at the center of the load-bearing base 2 to detect the displacement of the mounting base 1 and the tilt of the telescopic connecting rod 3. At least three sets of pressure sensors 7 are evenly distributed in the hollow cavity of the telescopic connecting rod 3 and on the periphery of the plumb bob 4 to assist in detecting the balance of the device.

[0022] The load-bearing base 2 has a first rigid support rod 21, a second rigid support rod 22, and a third rigid support rod 23 facing the ground at its bottom. The bottom of the load-bearing base 2 has a receiving groove 25 for respectively accommodating the first rigid support rod 21, the second rigid support rod 22, or the third rigid support rod 23. The first rigid support rod 21, the second rigid support rod 22, and the third rigid support rod 23 can rotate relative to the load-bearing base 2 and be stored in the receiving groove 25 to reduce the footprint of the device when not in use. A second transmitter 8 is provided on the first rigid support rod 21, and second detectors 9 are provided on the second rigid support rods 22 and 23 corresponding to the second transmitter 8 to detect the tilt of the load-bearing base 2. The load-bearing base 2 has two sets of drive mechanisms for moving the second rigid support rod 22 and the third rigid support rod 23 relative to the first rigid support rod 21, so as to adjust the load-bearing base 2 when the mounting base 1 is detected to be tilted.

[0023] The first transmitter 5 and the second transmitter 8 can be selected as laser transmitters or other wireless transmitters as needed. The first detector 6 and the second detector 9 are corresponding detectors, which determine the displacement change between the two by detecting the signals emitted by the first transmitter 5 and the second transmitter 8.

[0024] Example 2: A preferred embodiment of this utility model provides an auxiliary mechanism for tilt measurement in surveying engineering, which differs from the above embodiment only in that:

[0025] The first rigid support rod 21 is a hollow rod, in which a first spike 211 and a first fixing member 212 are provided in the cavity. The first spike 211 moves in extension and retraction relative to the first rigid support rod 21 by a spring 213. When the first spike 211 is retracted into the hollow cavity, the first fixing member 212 locks the first spike 211 in place. When the first fixing member 212 is released, the first spike 211 is driven into the ground by the elastic force of the spring 213.

[0026] Both the second rigid support rod 22 and the third rigid support rod 23 are hollow rods, with a second rigid spike 221 and an electric telescopic mechanism 222 distributed inside the cavity. The electric telescopic mechanism 222 can be selected to be an electric telescopic rod as needed. The electric telescopic mechanism 222 drives the second rigid spike 221 to telescopically move relative to the second rigid support rod 22 or the third rigid support rod 23, so as to control the height of the second rigid support rod 22 or the third rigid support rod 23 respectively. The second rigid spike 221 is inserted into the ground for reinforcement.

[0027] Each of the aforementioned drive mechanisms includes a drive motor 223, a drive gear 224, and a driven gear 225 located inside the load-bearing base 2. The output shaft of the drive motor 223 is connected to the drive gear 224, and the drive gear 224 meshes with the driven gear 225. The driven gear 225 is respectively connected to the second rigid support rod 22 or the third rigid support rod 23 to drive the second rigid support rod 22 or the third rigid support rod 23 to move respectively.

[0028] The bottom surface of the load-bearing base 2 is provided with an arc-shaped track hole 24 for the movement of the second rigid support rod 22 or the third rigid support rod 23, so as to limit the movement direction of the second rigid support rod 22 or the third rigid support rod 23.

[0029] Example 3: A preferred embodiment of this utility model provides an auxiliary mechanism for tilt measurement in surveying engineering, which differs from the above embodiments only in that:

[0030] The telescopic connecting rod 3 includes a main rod 31 connected to the load-bearing base 2, a support rod 33 connected to the mounting base 1, and several sets of connecting rods 32 located between the main rod 31 and the support rod 33. The main rod 31 and the connecting rods 32 adjacent to the main rod 31, the adjacent connecting rods 32, the connecting rods 32 adjacent to the support rod 33, and the support rod 33 are interlocked and fixed by elastic fasteners to adjust the height of the mounting base 1.

[0031] This tilt measurement auxiliary mechanism is used in conjunction with a geological compass, surveying benchmark, or geodetic surveying device. Its measurement method includes the following steps:

[0032] S1: When the load-bearing base 2 is placed at the tilt angle measurement point and the first fixing member 212 is loosened, the first spike 211 is inserted into the ground under the elastic force of the spring 213.

[0033] S2: The second transmitter 8 transmits signals to the controller along the horizontal direction to the second detector 9 located on the second rigid support rod 22 and the third rigid support rod 23 respectively. When the second detector 9 does not receive the transmission signal, the controller controls the drive mechanism and the electric telescopic mechanism 222 to adjust the position of the second rigid support rod 22 or the third rigid support rod 23 accordingly to ensure that the load-bearing base 2 is in a horizontal state.

[0034] S3: By pulling the telescopic link 3 to adjust the height of the mounting base 1, the first transmitter 5 sends a signal to the controller to the first detector 6, further ensuring that the mounting base 1 and the load-bearing base 2 are in a horizontal state and the telescopic link 3 is in a vertical state.

[0035] S4: When there is strong wind or ground vibration in the detection environment, the pressure sensor 7 is hit by the hammer 4 and sends a signal to the controller, which then reports a measurement abnormality.

[0036] This tilt measurement auxiliary mechanism can automatically level in both horizontal and vertical directions, eliminating the need for manual operation by the user when measuring tilt angles and the need for subjective adjustment of the compass. This reduces the workload of measurement and improves measurement accuracy, playing a positive role in improving geological work.

[0037] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
