Description

Technical Field

[0001] This utility model relates to the field of construction monitoring equipment technology, and in particular, to an in-pipe vibration device suitable for inclinometer tube installation. Background Technology

[0002] Deep displacement monitoring is a technology used to monitor internal displacement of geological structures and has been widely applied in the field of geotechnical engineering. In landslide treatment and slope and foundation pit support processes, it not only assists geotechnical engineers in determining the sliding surface but also monitors deep displacement changes in soil and rock masses, accurately determining their stability and development trend.

[0003] The deep displacement monitoring instrument uses a movable borehole inclinometer. First, a vertical hole of a certain depth is drilled at the monitoring location. Then, PVC inclinometer tubes are assembled and embedded into the hole segment by segment. The inclinometer tube contains two sets of guide grooves, within which the inclinometer pulleys move. When collecting data using the inclinometer, the bottom of the inclinometer tube is considered a fixed end with zero initial horizontal displacement. The inclinometer measures the changes in displacement of each upper segment relative to the initial displacement. The rate of displacement change and cumulative value of each segment accurately reflect the displacement changes of the soil and rock layers.

[0004] Deep displacement monitoring reflects stratum deformation through the deformation of pre-embedded inclinometer tubes, offering extremely high precision. Therefore, the contact between the inclinometer tube and the soil / rock mass during installation significantly impacts the monitoring results. In existing technologies, medium sand is used to fill the gap between the inclinometer tube and the borehole wall during installation. When the medium sand is densely packed, the deformation of the soil / rock mass can be observed relatively accurately. However, in actual construction, the gap between the inclinometer tube and the borehole wall is 10–30 mm. The medium sand, relying on its own weight, cannot achieve a dense state, and due to the influence of groundwater, local voids frequently occur. Because of these voids, the inclinometer tube vibrates slightly during data collection, resulting in irregular and fluctuating data with large errors, failing to accurately reflect stratum deformation.

[0005] Therefore, it is necessary to propose an in-pipe vibration device suitable for inclinometer installation to solve or at least alleviate the technical problem in the prior art where the inclinometer is prone to shaking due to loose backfill or local holes in the backfill material, resulting in unstable observation data and large measurement errors when tested by the inclinometer. Utility Model Content

The crossbar passes through the long slots and rollers are respectively provided on the two extended ends of the crossbar. The pin is inserted into the pin hole and passes through the middle of the crossbar, allowing the crossbar to be oscillating. The guide wheel assembly also includes a return torsion spring, which includes an upper torsion spring and a lower torsion spring located on the upper and lower sides of the crossbar, respectively. The upper torsion spring is located on one side of the pin and elastically resists the crossbar to drive the crossbar to swing downward.

[0032] Please refer to Figure 1 , Figure 2 as well as Figure 3This utility model provides an in-pipe vibration device 100 suitable for inclinometer tube installation, including an upper main rod 10, a middle main rod 20 and a lower main rod 30 connected sequentially along the axial direction. The middle main rod 20 is a hollow structure with a hollow cavity extending through the axial direction. It also includes an eccentric excitation assembly 40 and a guide wheel assembly 50 for matching with the guide groove of the inner wall of the inclinometer tube. The upper main rod 10 and the lower main rod 30 are respectively provided with guide wheel assemblies 50. The guide wheel assemblies 50 are oscillatingly arranged in the axial direction. The eccentric excitation assembly 40 includes a rotary driver 41 and a rotary eccentric block 42 disposed in the hollow cavity. The rotary driver 41 and the rotary eccentric block 42 are coaxially arranged to drive the rotary eccentric block 42 to rotate around the central axis to generate polarization excitation.

[0033] The present invention relates to an in-pipe vibration device 100 suitable for inclinometer installation. During the process of filling the gap between the borehole and the inclinometer hole, the guide wheel assembly 50 is matched with the guide groove and placed inside the inclinometer hole and placed at the bottom of the hole. The rotating eccentric block 42 is driven by the rotary driver 41 to provide a vibration source. Under the guidance of the guide wheel assembly 50, the device vibrates segment by segment from bottom to top, so that the filling material in the gap between the inclinometer hole and the borehole is vibrated and compacted. The horizontal displacement of the rock and soil can be accurately reflected on the inclinometer hole and accurately collected by the inclinometer. This can significantly reduce monitoring errors and improve work efficiency and accuracy.

[0034] In an optional embodiment of this utility model, the main rod, the middle main rod 20, and the lower main rod 30 are cylindrical rod-shaped structures. By connecting the upper main rod 10, the middle main rod 20, and the lower main rod 30 sequentially along the axial direction, and with the middle main rod 20 employing a hollow structure and having a hollow cavity extending axially, a stable main frame with vibration excitation function is constructed. The matching design of the guide wheel assembly 50 and the guide groove on the inner wall of the inclinometer tube ensures that the device can be stably and accurately positioned and moved within the inclinometer tube. The axially swingable arrangement of the guide wheel assembly 50 allows it to better adapt to irregularities that may exist inside the inclinometer tube, enhancing the flexibility and stability of the device's operation, and enabling it to better adapt to inclinometer tubes of different diameters and the irregularities that may exist inside. The irregular conditions enhance the applicability and stability of the device operation; the coaxial arrangement of the rotary driver 41 and the rotary eccentric block 42 in the eccentric vibration assembly 40 allows for efficient generation of polarization excitation when the rotary driver 41 drives the rotary eccentric block 42 to rotate around the central axis; ultimately, during the process of filling the gap between the inclinometer tube and the borehole with medium sand after the borehole is installed, the polarization excitation can be used to vibrate segment by segment from bottom to top, causing the filling material in the gap between the inclinometer tube and the borehole to vibrate and compact, thereby ensuring that the horizontal displacement of the rock and soil can be accurately reflected on the inclinometer tube and accurately collected by the inclinometer, greatly improving the accuracy of monitoring and significantly improving work efficiency.

[0035] Furthermore, the mounting end of the rotary actuator 41 is fixedly disposed in the hollow cavity, and the power output end of the rotary actuator 41 extends axially. The rotary eccentric block 42 includes a support bearing 421, a rotary shaft 422, and an eccentric block 423. The rotary shaft 422 is rotatably disposed in the hollow cavity through the support bearing 421, and the eccentric block 423 is fixedly disposed on the rotary shaft 422. The rotary shaft 422 is coaxially arranged with the rotary actuator 41, and the power input end of the rotary shaft 422 is circumferentially limited and connected to the power output end of the rotary actuator 41. The rotary actuator 41 is fixed at the mounting end within the hollow cavity, and its power output end extends axially, ensuring the stability and high efficiency of power transmission during operation. The rotating eccentric block 42 is rotatably mounted within the hollow cavity via a support bearing 421, allowing the rotating shaft 422 to rotate more smoothly and reducing energy loss. The eccentric block 423 is fixed on the rotating shaft 422, and the rotating shaft 422 is coaxially arranged with the rotary actuator 41 and circumferentially limited, ensuring that the power of the rotary actuator 41 can be accurately transmitted to the rotating eccentric block 42, causing it to rotate stably around the central axis to generate polarization excitation. Ultimately, this allows for more precise control of the vibration frequency and amplitude during vibration, further improving the compaction effect of the medium sand.

[0036] Understandably, the outer ring of the support bearing 421 is interference-fitted with the central main rod 20 in the hollow cavity, and the inner ring of the support bearing 421 is used to support the rotating shaft 422. The eccentric block 423 can be a sector block. The power input end of the rotating shaft 422 and the power output end of the rotating drive 41 can be connected by a coupling or by a spline connection.

[0037] Furthermore, the rotary actuator 41 is a rotary motor. The rotary actuator 41 includes a bearing housing 411, a motor rod 412, a rotor 413, and a stator 414. The motor rod 412 is rotatably mounted in the hollow cavity through the bearing housing 411. The rotor 413 is fixedly mounted on the motor rod 412. The stator 414 is located on the periphery of the rotor 413 and is fixedly mounted on the inner wall of the hollow cavity. The motor rod 412 is coaxially arranged and fixedly connected to the rotating shaft 422.

[0038] Furthermore, an oil seal seat 43 is provided between the rotary actuator 41 and the rotary eccentric block 42, and an oil seal 44 is provided on the oil seal seat 43. By arranging the oil seal seat 43 and the oil seal 44, dust, sand particles and other impurities that may exist in the hollow cavity are effectively prevented from entering the rotating parts of the rotary actuator 41 and the rotary eccentric block 42, avoiding equipment failure caused by wear due to impurities and greatly extending the service life of the equipment; at the same time, the oil seal 44 can also prevent the leakage of lubricating oil in the cavity, ensuring that the rotary actuator 41 and the rotary eccentric block 42 work under good lubrication conditions, reducing frictional resistance and improving energy utilization.

[0039] Furthermore, it also includes a head rubber end plug 60 located at the end of the lower main rod 30 away from the upper main rod 10. The head rubber end plug 60 is provided to act as a buffer when lowered to the bottom of the borehole, protecting the device itself from damage.

[0040] Furthermore, the upper main rod 10 and the lower main rod 30 are respectively provided with long slots extending along the axial direction. The long slots are located on the transverse mid-section and are arranged radially through. The upper main rod 10 and the lower main rod 30 are provided with pin holes on the positive mid-section. The guide wheel assembly 50 includes a crossbar 51, a pin 52 and a roller 53. The crossbar 51 is arranged through the long slot and the two extended ends of the crossbar 51 are respectively provided with rollers 53. The pin 52 is inserted into the pin hole and is arranged through the middle of the crossbar 51 so that the crossbar 51 can be swayed. The guide wheel assembly 50 also includes a return torsion spring 54. The return torsion spring 54 includes an upper torsion spring and a lower torsion spring located on the upper and lower sides of the crossbar 51, respectively. The upper torsion spring is located on one side of the pin 52 and elastically resists the crossbar 51 to drive the crossbar 51 to swing downward. The lower torsion spring is located on the other side of the pin 52 and elastically resists the crossbar 51 to drive the crossbar 51 to swing upward. By arranging upper and lower torsion springs, the crossbar 51 can quickly return to its original position after swinging under external force, always maintaining good contact with the guide groove on the inner wall of the inclinometer tube. During the movement of the device along the inclinometer tube, the guide wheel assembly 50 can adapt to inclinometer tubes of different diameters and can automatically adjust its angle according to the irregularities of the inner wall of the inclinometer tube, ensuring stable and smooth movement of the device. The jamming phenomenon when the device moves in the inclinometer tube improves the stability and efficiency of the device operation, thereby ensuring the continuity and uniformity of the medium sand vibration compaction process, which is conducive to improving the accuracy of monitoring data. Furthermore, by arranging upper and lower torsion springs, the eccentric excitation force is elastically loaded onto the inclinometer tube during the eccentric vibration process. The probability of damage to the inclinometer tube is low, and the continuous vibration is beneficial to the compaction of the medium sand filling.

[0041] Furthermore, the upper main rod 10 and the middle main rod 20 are connected by a threaded tightening fit, and the middle main rod 20 and the lower main rod 30 are connected by a threaded tightening fit. During the assembly and disassembly of the inclinometer installation device, the threaded tightening fit of the upper main rod 10, the middle main rod 20, and the lower main rod 30 facilitates quick operation for the operator, saving installation time.

[0042] Furthermore, at least two sets of guide wheel assemblies 50 are arranged on the upper main rod 10, with adjacent guide wheel assemblies 50 spaced apart axially. More preferably, at least two sets of guide wheel assemblies 50 are arranged on the lower main rod 30, with adjacent guide wheel assemblies 50 spaced apart axially. The arrangement of multiple sets of guide wheel assemblies 50 increases the contact points between the device and the inner wall of the inclinometer tube, further improving the stability of the device within the inclinometer tube. During device movement and vibration, multiple sets of guide wheel assemblies 50 can better distribute the weight of the device and the force generated by vibration, making the device operate more smoothly; at the same time, the axially spaced arrangement allows the guide wheel assemblies 50 to better adapt to the conditions of different parts of the inclinometer tube, ensuring stable operation of the device throughout the entire length of the inclinometer tube.

[0043] Furthermore, the lower main rod 30 has an oil chamber at one end facing the middle main rod 20, and the middle main rod 20 has an oil pan at one end facing the lower main rod 30. The oil chamber and the oil pan are connected by an oil suction nozzle. During operation, the lubricating oil in the oil chamber can flow to the oil pan through the oil suction nozzle, providing continuous lubrication for the connection between the lower main rod 30 and the middle main rod 20, as well as related rotating parts.

[0044] Furthermore, the upper main rod 10 is provided with a through-hole that extends axially, and a terminal block 70 is provided at the top of the upper main rod 10. The through-hole facilitates the connection of the device with external power sources, control systems, etc. In a specific implementation, one end of the cable is connected to the rotary driver 41, and the other end of the cable extends through the through-hole to the outside of the upper main rod 10. In a specific embodiment of this utility model, in order to avoid interference from the crossbar 51, the through-hole near the guide assembly is eccentrically arranged, and the through-holes on the lower and upper sides of the guide assembly are central shaft holes.

[0045] During deep displacement monitoring, the inclinometer tube is lowered into the pre-drilled hole section by section. Medium sand is used to fill the gap between the inclinometer tube and the hole. After the medium sand is poured in, the crossbar 51 of the lower main rod 30 and the upper main rod 10 is manually turned clockwise to insert the inclinometer tube vibrating device 100 suitable for inclinometer tube installation into the inclinometer tube. The crossbar 51 is in close contact with the inner wall of the inclinometer tube under the action of torsion springs (upper torsion spring and lower torsion spring). It is lowered to the bottom of the hole by rollers 53. The external power supply is turned on, and the eccentric excitation component 40 works to provide a vibration source to drive the inclinometer tube to vibrate. After the vibration is compacted, the inclinometer tube vibrating device 100 suitable for inclinometer tube installation is lifted up section by section to vibrate in stages, so that the medium sand is compacted until the inclinometer tube vibrating device 100 suitable for inclinometer tube installation is lifted out of the borehole opening.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
