Description

Technical Field

[0001] An adjustable support for a micro-motion detection device is provided, which is used to stably support the micro-motion detection device and belongs to the field of adjustable support technology. Background Technology

[0002] The intelligent inversion construction method for non-destructive micro-motion detection of sloping terrain along railway sections avoids physical damage to the railway subgrade (i.e., directly placing the micro-motion detection device at the measuring point or shallowly inserting it), thus protecting the integrity of the existing structure. Its high-precision defect location capability can eliminate potential safety hazards in advance, reducing the risk of geological disasters during railway operation. Its non-intrusive detection reduces earthwork excavation and ecological damage, aligning with environmental protection principles. Accurate data intelligent inversion and calculation can avoid excessive engineering reinforcement, saving building materials. It can provide new solutions for complex scenarios (such as mountain railways and urban elevated sections) and has significant industry promotion value.

[0003] In existing technologies, when micro-motion detection is required at a measuring point, the micro-motion detection device is usually placed or inserted directly into the measuring point. Although this method allows for rapid deployment of the micro-motion detection device, it presents the following technical problems: Fixing the measuring point position by its own weight or by shallow insertion into the ground can easily lead to poor stability. In particular, when the micro-motion detection device is placed on a slope, it is very easy for landslides or tilting to occur, which can easily cause inaccurate measurement positions of the micro-motion detection device or inaccurate measurement components at the measuring point. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable support for a micro-motion detection device, which solves the problem that the existing micro-motion detection device is fixed at the measuring point position by its own weight or the force of shallow insertion into the ground, which easily leads to poor stability. In particular, when the micro-motion detection device is placed on a slope, it is very easy for landslides or tilting to occur, which can easily cause inaccurate measurement position of the micro-motion detection device or inaccurate measurement components at the measuring point.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable support for a micro-motion detection device includes a fixed structure fixed to the micro-motion detection device and a support structure that moves in conjunction with the fixed structure to support the micro-motion detection device.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Example 1

[0026] To address the issue that existing technologies, which fix the measuring point at its location using gravity or shallow insertion into the ground, are prone to instability, especially when the micro-motion detection device is placed on a slope, which is highly susceptible to landslides or tilting, thus leading to inaccurate measurement positions or inaccurate measurement components at the measuring point. Figure 1-8 As shown, an adjustable support for a micro-motion detection device is provided, including a fixed structure 2 fixed on the micro-motion detection device 1, and a support structure 3 that movably cooperates with the fixed structure 2 to support the micro-motion detection device 1.

[0027] In practice, after marking the location of the measuring point, the fixing structure is first fixed to the designated position of the micro-motion detection device 1. Then, the supporting structure is used to align the micro-motion detection device 1 with the measuring point. For example, the pointed cone of the micro-motion detection device is aligned with the measuring point and inserted into the ground. At the same time, the supporting structure is adjusted to support the micro-motion detection device 1. In this embodiment, the fixing structure is fixed to the designated position of the micro-motion detection device, and the supporting structure supports the micro-motion detection device according to the current terrain or inserts it shallowly at the measuring point. Due to the supporting force of the supporting structure, the stability of the micro-motion detection device at the measuring point can be guaranteed, especially the stability when placed on a slope, effectively avoiding landslides or tilting, thereby improving the accuracy of the measurement position of the micro-motion detection device or the accuracy of the measurement components at the measuring point.

[0028] Example 2

[0029] Based on Embodiment 1, the fixing structure 2 includes a clamping piece 4 that cooperates with the micro-motion detection device 1. The shape of the clamping piece is set according to the micro-motion detection device 1. Fixing blocks 6 with mounting holes 5 are set on both ends of the clamping piece 4. Fixing bolts 7 and nuts that cooperate with the mounting holes 5 to fix the clamping piece 4 to the micro-motion detection device 1 are provided. A limiting block 8 is provided on the fixing block 6 between the end connected to the clamping piece 4 and the mounting hole. The purpose of setting the fixing block with mounting holes on the clamping piece is to facilitate the adjustment of the fixed position on the micro-motion detection device to meet the requirements. The purpose of setting the limiting block on the fixing block is to facilitate the subsequent cooperation with the support structure to limit the micro-motion detection device, and at the same time to distribute the force on the support structure.

[0030] In practice, markings that match the fixing structure can be set on the micro-motion detection device 1. When fixing is required, the two clips 4 are placed on both sides of the micro-motion detection device 1 and fixed by the fixing bolts 7 and nuts cooperating with the mounting holes 5. Otherwise, they can be removed.

[0031] Example 3

[0032] Based on Embodiment 2, a rubber protective pad 9 is provided on the inner side of the clip 4 to facilitate the protection of the micro-motion detection device and avoid easy wear under force.

[0033] Example 4

[0034] Based on embodiment 3, the support structure 3 includes a collar 10. On one opposite side of the collar 10, there is a sliding groove A11 that slides and engages with the fixing block 6 between the limiting block 8 and the clamping piece 4 to separate the micro-motion detection device 1 from the ground and has an open top. On the other opposite side of the collar 10, there is a sliding groove B12 that slides and engages with the fixing block 6 between the limiting block 8 and the clamping piece 4 to contact the micro-motion detection device 1 with the ground and has an open top. Support components 13 are evenly spaced along the circumference of the collar 10 to provide adjustable support for each side of the collar 10. The number of support components 13 is determined according to actual needs, such as 4, 6, 8, etc. The support assembly 13 includes a U-shaped block 14 disposed on the collar 10. A threaded hole 15 is provided on the opposite side of the U-shaped block 14. A bolt 16 is threaded onto the threaded hole 15. A support foot 17 is rotatably disposed on the bolt 16. On the opposite side of the nut of the bolt 16, a limiting block 18 is provided on the bolt 16 in the U-shaped block 14 to limit the movement of the support foot 17. An internal threaded hole 19 is provided on the internal threaded hole 19. A threaded rod 20 is provided on the internal threaded hole 19. A support ball 21 is provided at the bottom of the threaded rod 20.

[0035] In practice, if it is necessary to fix the micro-motion detection device 1 on the slope, first fix the fixing structure 2 onto the micro-motion detection device 1, and then mate the fixing structure with the sliding groove A on the collar 10. At this time, the fixing structure 2 and the support structure 3 can be moved as a whole to make the designated structure of the micro-motion detection device 1 correspond to the measuring point. At this time, it can be observed through the sliding groove B12. If they correspond, the bottom of the collar 10 should preferably be placed on the ground. Then adjust the support component 13 on the lower side of the slope (the support component 13 on the upper side can be separated from the ground and does not play a supporting role). If it is necessary to adjust the angle, loosen the screw 16 by rotating it. The support feet are opened and their angle is adjusted by rotation. The threaded rod 20 is then rotated to engage with the internal threaded hole 9, extending the threaded rod out of the hole until the support ball contacts the slope. The bolt is then rotated in the opposite direction, and the support feet are fixed against the U-shaped block on the opposite side of the limit block under the push of the limit block, ensuring stability during support. The micro-motion detection device is then slid out of the groove A, and the fixing block is rotated to position B and slid into groove B. This allows the micro-motion detection device to be placed on the ground or shallowly inserted underground, effectively avoiding inaccurate positioning of the micro-motion detection device. Conversely, the threaded rod is retracted. When applied to other scenarios, the support components are adjusted according to actual needs. When the micro-motion detection device 1 is placed on the bottom surface or shallowly inserted (the insertion depth range can be determined according to actual needs) underground, the fixing block is in contact with or separates from the bottom of groove B. In practice, auxiliary tools can be used to determine whether the central axis of the measuring point is coaxial with the central axis of the ring. If so, the support components can be adjusted first to ensure the stability of the ring. Then, the micro-motion detection device 1 with the fixed structure is placed in the ring to contact the ground or inserted into the ground, and the fixed block is made to cooperate with the slide B.

[0036] Example 5

[0037] Based on embodiment 4, the support ball 21 is provided with anti-slip protrusions 22, the purpose of which is to increase the friction between the support ball and the ground.

[0038] Example 6

[0039] Based on embodiment 5, the support foot 17 has a tapered structure that is larger at the top and smaller at the bottom, in order to reduce material consumption. Of course, other structures are also possible.

[0040] Example 7

[0041] Based on embodiment 6, the collar 10 is made of transparent material, or the collar 10 is provided with a transparent window for observing one side of the bottom of the micro-motion detection device 1. The purpose of limiting the collar to a transparent material or providing a transparent window on the collar is to facilitate observation of whether the designated position of the micro-motion detection device inside corresponds to the measuring point.

[0042] Example 8

[0043] Based on embodiment 7, a reinforcing rib 23 is provided on the outer ring of the collar 10 below the slide groove B12 to avoid the problem of easy damage when the slide groove B is subjected to force.

[0044] In practice, the micro-motion detection device 1 can be placed or inserted into the designated measurement first, and then the groove B or groove A on the collar 10 can be slid into the fixed block. Finally, the support components can be adjusted to contact the ground to support each side of the structure. The appropriate method can be selected according to actual needs.

[0045] There are multiple ways to fix the micro-motion detection device 1 in this case. The specific method to be used can be selected according to the actual needs.
