[0001] This utility model relates to the field of building seismic isolation technology, specifically to a positioning control system for the support of a single seismic isolation layer. Background Technology

[0002] With the continuous development of society and the constant improvement and enhancement of seismic resistance requirements for building engineering, traditional seismic resistance technologies that rely on increasing or thickening steel bars and load-bearing columns to strengthen the strength and stiffness of components and rigidly resist earthquakes have been gradually phased out.

[0003] In the process of developing this application, the applicant discovered that the seismic isolation strength of existing seismic isolation layers is usually set at a fixed value, which limits their application scope. Utility Model Content

[0004] In view of the problems existing in the above-mentioned seismic isolation layers, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a positioning control system for the single support of the seismic isolation layer, which solves the problem that the seismic isolation strength of the existing seismic isolation layer is usually fixed, resulting in a limited range of applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seismic isolation layer single-unit support positioning control system includes an upper support pier, a lower support pier, an upper support plate, and a lower support plate. The upper support plate is fixedly connected to the upper support pier, and the lower support plate is fixedly connected to the lower support pier.

A first spring is movably fitted on the surface of each sleeve and the corresponding support rod. A sleeve is movably fitted on the tube wall of each sleeve. The two ends of each first spring are fixedly connected to the upper support plate and the sleeve, respectively. An adjusting support mechanism is provided on each sleeve. When the adjusting support mechanism moves up or down, it drives the sleeve to move synchronously to reduce or increase the remaining compression of the first spring.

[0008] Optionally, the adjusting support mechanism includes a mounting plate, a drive rod, and multiple insert rods. A support plate is fixedly connected between the four sleeves. A fixing plate fixedly connected to the support plate is movably sleeved on the rod wall of the drive rod.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a positioning control system for the single support of the seismic isolation layer.

[0024] This utility model provides, for example Figure 1-4 The isolation layer single-unit bearing positioning control system shown includes an upper support 1, a lower support 2, an upper support plate 3, and a lower support plate 4. The upper support plate 3 is fixedly connected to the upper support 1, and the lower support plate 4 is fixedly connected to the lower support 2. Four sleeves 5 are fixedly arranged around the upper surface of the lower support plate 4 (due to...). Figure 1 For the frontal sectional view, four sleeves 5 are arranged in a circumferential array at equal intervals on the lower support plate 4. Therefore, in Figure 1 Only three sleeves 5 are visible in the structure. Each sleeve 5 has a support rod 6 that is movably inserted inside. The upper end of each support rod 6 is fixedly connected to the upper support plate 3. Each sleeve 5 has two symmetrical slots on its side wall. Each slot has a limiting rod 7 that is slidably installed inside and fixedly connected to the wall of the corresponding support rod 6. The limiting rod 7 can prevent the support rod 6 and the sleeve 5 from separating. Each sleeve 5 and the surface of the corresponding support rod 6 are movably fitted with a first spring 8. Each sleeve 5 has a sleeve 9 that is movably fitted on its wall. The two ends of each first spring 8 are fixedly connected to the upper support plate 3 and the sleeve 9, respectively. When the upper support plate 1 is compressed, the support rod 6 can move downward along the axis of the sleeve 5. Each sleeve 9 is equipped with an adjusting support mechanism. When the adjusting support mechanism moves up or down, it drives the sleeve 9 to move synchronously to reduce or increase the remaining compression of the first spring 8.

[0025] By setting up a sleeve 9 and a corresponding adjusting support mechanism, and by adjusting the up-and-down movement of the supporting mechanism to drive the sleeve 9 to move synchronously, the compression degree of the first spring 8 can be adjusted, thereby achieving the adjustment of the vibration isolation strength and enriching its application range. In this way, operators can adjust the vibration isolation strength according to actual needs.

[0026] like Figure 1-2 As shown, the adjusting support mechanism includes a mounting plate 10, a drive rod 11, and multiple insert rods 12. A support plate 14 is fixedly connected between the four sleeves 9. A fixing plate 15, which is fixedly connected to the support plate 14, is movably sleeved on the rod wall of the drive rod 11. One end of the drive rod 11 is fixedly connected to the mounting plate 10 and is fixedly connected to the multiple insert rods 12 through the mounting plate 10. Multiple first insertion holes are symmetrically opened on the side wall of the sleeve 9, and multiple second insertion holes are symmetrically opened on the side wall of the sleeve 5. Each insert rod 12 is movably inserted into the corresponding first insertion hole and the corresponding second insertion hole. By movably inserting the multiple insert rods 12 into the corresponding second insertion hole and the first insertion hole, the position of the sleeve 9 on the sleeve 5 can be fixed.

[0027] like Figure 1-4 As shown, a rotating rod 16 is provided through the support plate 14. The rotating rod 16 is rotatably connected to the support plate 14 and is located between four sleeves 5. A disc 17 is fixedly connected to the upper end of the rotating rod 16. Four arc-shaped plates 18 are fixedly arranged around the side wall of the disc 17. A ball bearing 19 is rotatably provided at the end of each drive rod 11 near the disc 17. Each ball bearing 19 is in contact with the side wall of the corresponding arc-shaped plate 18. By using the ball bearing 19, the friction between the drive rod 11 and the corresponding arc-shaped plate 18 can be reduced, so as to drive the rotating rod 16 to drive the disc 17 to rotate.

[0028] like Figure 3 As shown, each drive rod 11 has a baffle 20 fixedly sleeved on its wall. Each baffle 20 and the side wall of the corresponding fixed plate 15 are fixedly connected to a second spring 21 that is movably sleeved on the corresponding drive rod 11. Using the baffle 20 and the second spring 21, as the force compressing the second spring 21 gradually decreases, the second spring 21 gradually transitions from a compressed state to a natural state. At this time, the second spring 21 drives the drive rod 11, the mounting plate 10, and the insertion rod 12 to move away from the sleeve 9, causing the insertion rod 12 to gradually separate from the second insertion hole. Furthermore, when the second spring 21 returns to its natural state, the insertion rod 12 separates from the second insertion hole, facilitating the adjustment of the height position of the sleeve 9, and consequently, the adjustment of the remaining compression of the first spring 8.

[0029] like Figure 2As shown, a torsion spring 22 is movably sleeved on the wall of the rotating rod 16. The two ends of the torsion spring 22 are fixedly connected to the support plate 14 and the rotating rod 16, respectively. The elastic force of the torsion spring 22 is greater than the sum of the elastic forces of the four second springs 21. By utilizing the torsion spring 22, the sum of the elastic forces of the four second springs 21 can be overcome, ensuring that each second spring 21 is in a compressed state. When no external force drives the rotating rod 16 to rotate, the rotating rod 16 remains stationary due to the restriction of the torsion spring 22. When the second springs 21 are in a compressed state, it indicates that the driving rod 11 drives the baffle 20 closer to the fixed plate 15. Simultaneously, the driving rod 11 drives the insertion rod 12 to be inserted into the second insertion hole through the mounting plate 10, ensuring that each insertion rod 12 is stably inserted into the corresponding second insertion hole, thus fixing the height of the sleeve 9.

[0030] like Figure 1 As shown, a knob 13 is fixedly connected to the lower end of the rotating rod 16. The knob 13 can be used to drive the rotating rod 16 to rotate.

[0031] Working principle: Under normal working conditions, the elastic force of the torsion spring 22 is greater than the sum of the elastic forces of the four second springs 21, and all four second springs 21 are in a compressed state. Each insertion rod 12 is movably inserted into the corresponding first insertion hole and second insertion hole. At this time, the sleeve 9 is fixed on the sleeve 5.

[0032] When it is necessary to adjust the vibration isolation strength of the entire device, the rotating rod 16 is rotated by turning the knob 13. Since the rotating rod 16 is fixedly connected to the disc 17, the rotation of the rotating rod 16 drives the disc 17 to rotate, and the rotation of the disc 17 drives the four arc-shaped plates 18 installed on it to rotate. Since the elastic force of the torsion spring 22 is greater than the sum of the elastic forces of the four second springs 21, when the knob 13 is not turned, the rotating rod 16 is kept stationary by the elastic force of the torsion spring 22, so that the end of the free end of each arc plate 18 is in contact with the corresponding ball 19. When the rotating rod 16 is turned to drive the arc plate 18 to rotate clockwise (viewed from above) through the disc 17, the free end of the arc plate 18 gradually moves away from the corresponding ball 19. The four second springs 21 are reset by their own elastic force and push the corresponding baffle 20 to move away from the sleeve 9 during the reset process. By pushing the baffle 20, the driving rod 11, the mounting plate 10 and the insertion rod 12 move away from the sleeve 9 (i.e., move towards the disc 17), thereby moving the insertion rod 12 out of the second insertion hole in the sleeve 5. At this point, manually adjust the support plate 14 to the required height position. After adjusting the height position of the support plate 14, release the knob 13. The torsion spring 22 overcomes the sum of the elastic forces of the four second springs 21 and drives the rotating rod 16 to rotate in the opposite direction. This drives the four arc plates 18 to rotate in the opposite direction through the disc 17. During the reverse rotation of the arc plates 18, the corresponding ball bearings 19 are squeezed. After being squeezed, the ball bearings 19 drive the corresponding drive rod 11 to move closer to the sleeve 9. During the movement of the drive rod 11 closer to the sleeve 9, the corresponding mounting plate 10 drives the corresponding second insertion rod 12 to insert into the second insertion hole, thereby fixing the height position of the support plate 14 and the sleeve 9.

[0033] If the height of the support plate 14 and the sleeve 9 is increased, the four first springs 8 will be further compressed, the compressibility of the first springs 8 will decrease, and the shock absorption capacity will be reduced.

[0034] If the height of the support plate 14 and the sleeve 9 is lowered, the compression degree of the four first springs 8 will decrease, the compressibility of the first springs 8 will increase, and the shock absorption capacity will be enhanced.

[0035] When the upper support 1 is subjected to vertical downward pressure, the upper support plate 3 moves downward under the action of the upper support 1, compressing the four first springs 8, so as to buffer the shock through the contraction of the first springs 8.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
