Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to an intelligent monitoring-type buffer adjustment device for beam-column connections in subway stations. Background Technology

[0002] Currently, common beam-column connection buffer devices in structural engineering often employ a combination of rigid connections and spring dampers. These typically consist of a welded frame, preloaded spring assemblies, and bolt fasteners, dissipating foundation energy through the linear compression of the springs. Such devices are widely used in seismic nodes of high-rise buildings, bridge expansion joints, subway station seismic nodes, and heavy machinery bases. Their core function is to absorb external load impacts and reduce structural vibration transmission through elastic elements with fixed stiffness. Existing technologies often employ symmetrically distributed axial springs or hydraulic damping systems, with adjustment primarily relying on manual pre-tightening of bolts to change the initial pressure, lacking dynamic adjustment capabilities during operation.

[0003] In the aforementioned traditional structures, the spring preload is statically set, which cannot match dynamically changing load conditions in real time, leading to insufficient buffering under overload or excessive rigidity under low load. Symmetrically arranged buffer components struggle to decompose multi-dimensional composite stresses, easily causing localized stress concentrations and accelerating component fatigue. Manual adjustment relies on periodic maintenance and has limited accuracy, failing to achieve closed-loop feedback control of load and buffering parameters. The mechanical transmission lacks a self-locking mechanism, making it prone to displacement drift under continuous vibration, affecting the long-term stability of the structure. These shortcomings limit the response speed and adaptive capability of the buffer system under complex working conditions. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent monitoring-type buffer adjustment device for beam-column connections in subway stations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent monitoring-type beam-column connection buffer adjustment device for subway stations, comprising:

[0006] The base column and the crossbeam, wherein there are two base columns and the crossbeam is perpendicular to the two base columns;

[0007] The two fixing boxes are respectively bolted to the top of the two base columns;

[0008] A connecting mechanism is installed on the inner side of each of the two fixed boxes and is connected to the crossbeam;

[0009] A drive mechanism is provided, which is respectively disposed inside the two fixed boxes and connected to the connecting mechanism;

[0010] A buffer mechanism is mounted on the connecting mechanism.

[0011] In one feasible implementation, the connecting mechanism includes: a disc, two discs respectively fixedly disposed on the inner sidewalls of the two fixed boxes; a socket, two sockets respectively opened on one side of the two discs, and the crossbeam inserted into the two sockets; and a notch, a plurality of notches respectively opened in a circular array on the edge of the disc.

[0012] In one feasible embodiment, the buffer mechanism includes: a sliding groove, wherein a plurality of sliding grooves are respectively formed on the disk in pairs and located in the middle of the plurality of slots; a slider, wherein a plurality of sliders are movably disposed at the plurality of sliding grooves; a shock-absorbing spring, wherein one end of the plurality of shock-absorbing springs is respectively fixedly disposed on one side of the plurality of sliders; and a contact member, wherein one end of the plurality of contact members is respectively fixedly disposed on the other end of the plurality of shock-absorbing springs.

[0013] In one feasible implementation, the other end of several of the contact elements is configured as an arc surface and is in close contact with the outer side of the outer wall of the beam.

[0014] In one feasible implementation, the driving mechanism includes: a rotating ring, two of which are rotatably mounted on the outer side of the outer wall of the disc; a driving motor, two of which are respectively fixedly disposed inside the two fixed boxes; a linkage assembly, the linkage assembly being disposed on the two driving motors and the two rotating rings; and a plurality of tilting blocks, a plurality of which are respectively fixedly disposed on the inner side of the rotating rings and in close contact with the plurality of sliders.

[0015] In one feasible implementation, the linkage component includes: a worm gear, two worm gears respectively fixedly mounted on the drive end of the drive motor; and worm teeth, a plurality of worm teeth respectively opened on the outer edge of the two rotating rings and meshing with the worm gears.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: When the drive motor drives the worm gear to rotate, the worm gear meshing transmission converts the rotational motion into the circumferential rotation of the ring. The inclined block on its inner side periodically presses against the slider as the phase of the ring changes. The geometric characteristics of the inclined surface are used to convert the rotational motion into the linear displacement of the slider along the slide groove. Thus, the clamping force of the contact part on the arc surface of the crossbeam is dynamically adjusted by compressing the damping spring. The self-locking characteristics of the worm gear ensure that any adjustment position can be stably maintained, avoiding accidental displacement caused by load fluctuations. The precise control of the phase and stroke of the inclined block enables the slider displacement to be multi-level adjustable. Combined with the nonlinear deformation characteristics of the damping spring group, it can achieve initial buffering through preset prestress and dynamically correct the contact pressure according to real-time monitoring data. When the load changes in the opposite direction, the drive motor reverses to drive the ring to reset, and the energy stored in the damping spring is released to promote the rapid response of the system. Ultimately, it achieves control, dynamic adaptive adjustment and multi-dimensional vibration suppression of the buffer parameters of the beam-column connection node of the subway station, significantly improving the stability and durability of the subway station.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: an intelligent monitoring type subway station beam-column connection buffer adjustment device, including: a base column 1, a crossbeam 2, a fixing box 3, a connecting mechanism, and a buffer mechanism. Two base columns 1 are provided, and the crossbeam 2 is perpendicular to the two base columns 1. The two fixing boxes 3 are respectively bolted to the top of the two base columns 1. The connecting mechanism is respectively installed on the inner side of the two fixing boxes 3 and connected to the crossbeam 2. A driving mechanism is respectively installed on the inner side of the two fixing boxes 3 and connected to the connecting mechanism. The buffer mechanism is installed on the connecting mechanism.

[0024] It should be noted that this device can be used with different sensors. When simulating an external environment for testing beams and columns, the intelligent monitoring system is triggered, and the drive mechanism first starts inside the fixed box 3. Through power output, it drives the connecting mechanism to rotate axially. During rotation, the connecting mechanism applies progressive vertical pressure to the buffer mechanism, causing the damping spring 9 inside the buffer mechanism to compress and deform, thereby dynamically adjusting the spring's prestress coefficient. Simultaneously, the drive mechanism continuously fine-tunes the rotation angle based on real-time monitoring data, ensuring a dynamic balance between the pressure exerted by the connecting mechanism on the buffer mechanism and the environmental load. Throughout this process, the fixed box 3 maintains a rigid connection between the base column 1 and the beam 2, transmitting the adjusted buffer force to the overall structure through bolt joints. The beam 2, through torque transmission via the connecting mechanism, achieves multi-dimensional stress distribution, ultimately completing the adaptive buffer adjustment of the beam-column connection joint under varying load conditions. The entire process operates cyclically through the automated control of the drive mechanism, achieving real-time monitoring of the structural response and intelligent matching of buffer parameters.

[0025] As a preferred embodiment, the connecting mechanism further includes: a disc 4, a socket 5, and a slot 6. The two discs 4 are respectively fixedly installed on the inner side walls of the two fixed boxes 3; the two sockets 5 are respectively opened on one side of the two discs 4, and the crossbeam 2 is inserted into the two sockets 5; a number of slots 6 are respectively opened in a circular array on the edge of the disc 4.

[0026] It should be noted that when the crossbeam 2 is subjected to external loads, its two ends are rigidly connected to the side walls of the two disks 4 through the insertion holes 5, and the load is directly transmitted to the disk 4 body along the inner wall of the insertion holes 5. With the dynamic change of the load direction or intensity, the crossbeam 2 generates a small displacement corresponding to the load direction in the insertion holes 5. At this time, the buffer component establishes a multi-level stress release channel. The dynamic optimization of the load transfer path and the adaptive balance of structural stress are completed through deformation and elastic energy storage mechanism.

[0027] As a preferred embodiment, the buffer mechanism further includes: a slide groove 7, a slider 8, a shock-absorbing spring 9, and a contact element 10. Several slide grooves 7 are formed in pairs on the disc 4 and are located in the middle of several slots 6. Several sliders 8 are movably disposed at several slide grooves 7. One end of several shock-absorbing springs 9 is fixedly disposed on one side of several sliders 8. One end of several contact elements 10 is fixedly disposed on the other end of several shock-absorbing springs 9.

[0028] It should be noted that when the load transmitted by the beam 2 is applied to the contact member 10, the contact member 10 is compressed and generates axial displacement, which pushes the damping spring 9 fixed to it to undergo compression deformation; as the load intensity changes, the contact members 10 at different positions are compressed in sequence, and the multi-directional vibration energy is absorbed in synergy through the nonlinear deformation of the damping spring 9; thus realizing the graded dissipation of impact energy and the multi-dimensional suppression of structural vibration.

[0029] As a preferred option, furthermore, the other end of several contact elements 10 is set as an arc surface and is in close contact with the outer side of the outer wall of the crossbeam 2.

[0030] As a preferred embodiment, the driving mechanism further includes: a rotating ring 11, a drive motor 12, a linkage component, and tilting blocks 13. The two rotating rings 11 are rotatably mounted on the outer side of the outer wall of the disc 4; the two drive motors 12 are respectively fixedly installed inside the two fixed boxes 3; the linkage component is respectively installed on the two drive motors 12 and the two rotating rings 11; and several tilting blocks 13 are respectively fixedly installed on the inner side of the rotating rings 11 and are in close contact with several sliders 8.

[0031] As a preferred embodiment, the linkage assembly further includes: a worm 14 and worm teeth 15, with the two worms 14 respectively fixedly mounted on the drive end of the drive motor 12; and a plurality of worm teeth 15 respectively opened on the outer edge of the two rotating rings 11 and meshing with the worms 14.

[0032] It should be noted that when the intelligent monitoring system triggers the adjustment command, the drive motor 12 starts and drives the worm gear 14 at its output end to rotate at high speed. The worm gear 14 meshes with the worm teeth 15 distributed around the outer edge of the rotating ring 11, converting the rotational motion into the circumferential rotation of the rotating ring 11 around the outer wall of the disk 4. As the rotating ring 11 continues to rotate, the inclined blocks 13 fixedly installed on its inner side are displaced due to their eccentric layout. When each inclined block 13 rotates to the phase corresponding to the slider 8, it uses the contact relationship between its inclined surface and the surface of the slider 8 to push the slider 8 to produce a quantitative displacement along the axial track of the slide groove 7. The movement of the slider 8 changes the arc-shaped pressing force of the contact element 10 on the outer wall of the crossbeam 2 through the damping spring 9. The self-locking characteristic of the worm gear 14 and worm tooth 15 meshing ensures that the rotating ring 11 remains locked in position when stopped at any angle. When the load changes and reverse adjustment is required, the drive motor 12 reverses to make the rotating ring 11 rotate in the opposite direction. The tilting block 13 then disengages from the contact area of ​​the slider 8. At this time, the elastic restoring force of the damping spring 9 drives the slider 8 to slide back along the groove 7 and reset. The arc surface clamping force of the contact member 10 is simultaneously weakened. By controlling the rotation angle of the worm gear 14, the rotating ring 11 can finely adjust the action phase and stroke of the tilting block 13 to achieve multi-level adjustable displacement of the slider 8. This allows for dynamic matching of the prestress parameters required by the buffer mechanism under different working conditions, completing closed-loop feedback adaptive adjustment based on real-time monitoring data.
