Description

Technical Field

[0001] The invention relates to the technical field of vibration control of steel structure canopies, in particular to a vibration control device suitable for temperature joints of steel structures. Background Art

[0002] High-speed railway steel structure canopy is a large-scale shelter facility specially designed and built for high-speed railway platforms. Its main structural frame is made of high-strength steel and is built through scientific and reasonable design and meticulous construction. The shape and size of the canopy will be customized according to the specific scale and layout of the platform, often showing the remarkable characteristics of openness, spaciousness, transparency and brightness. The covering materials used on the top and sides may be aluminum plates, tempered glass, etc., which can not only effectively block the invasion of wind and rain, but also ensure sufficient natural lighting. At the structural design level, it fully considers various factors such as wind load and vibration brought by the high-speed operation of high-speed trains, so it has extremely excellent wind and earthquake resistance.

As for the movable mechanism 7, the base plate 71 is fixed on the purlin 1, providing a solid foundation for the entire structure. The cooperation of the reserved groove 72 and the sliding block 73 enables the viscous damper 4 to move flexibly within a certain range to adapt to the deformation and vibration of the steel structure. The fixing sleeve 74 ensures the stable connection between the viscous damper 4 and the sliding block 73. The countersunk mounting hole 76 on the mounting plate 75 is not only convenient for installation, but also makes the surface of the installed component smooth and beautiful.

[0027] The working principle of the present invention is: during application, the device is installed at the purlin 1 through the mounting hole 76 and the mounting plate 75. During installation, the telescopic mechanism 6 is adjusted by the adjusting mechanism 3 to adapt to the installation and use of different purlin 1 spacings. When the two purlins 1 produce horizontal relative deformation due to temperature, due to the design of the reserved groove 72 on the base plate 71 and the sliding block 73 on the inner side, when it undergoes lateral activity deformation, it can slide and displace on the inner side of the reserved groove 72 through the sliding block 73. At this time, the viscous damper 4 can be reserved for lateral activity without generating lateral restraining force, thereby releasing the temperature deformation of the purlin 1. When the left and right purlins 1 induce vibration response due to the aerodynamic load of the train, the vibration between the left and right purlins 1 is not synchronized, resulting in vertical relative displacement. The two viscous dampers 4 work simultaneously to assist in damping, thereby reducing the vibration response at the temperature joint of the structure, so that the device can play a better damping and buffering role, and can improve the overall performance of the device.

[0028] By setting the adjusting mechanism 3 and the telescopic mechanism 6, the device can be used to pull the armrest 336 to drive the displacement block 334 inside the side rail 332 to move upward, and the displacement block 334 moves upward to drive the limit to disengage from the positioning position, and disengage from the positioning hole 331 and the limit frame 335, and the telescopic spring 333 is in a taut state. At this time, there is no positioning structure between the adjusting disk 32 and the fixed block 31. At this time, the operating handle can be pulled to drive the adjusting disk 32 to rotate, and the rotation of the adjusting disk 32 can drive the screw rod 62 to rotate, and the rotation of the screw rod 62 can drive the slider 63 to slide and displace, and the threads at both ends of the screw rod 62 are rotated in opposite directions, so the slider 63 can slide back and forth, and the reciprocating sliding of the slider 63 can drive the linkage rod 643 to move. The first hinge seat 641 and the second hinge seat 642 are linked to each other, so that the side panels 51 on both sides can be pushed or pulled toward both sides. The inner side spacing of the side panels 51 can be quickly adjusted by rotating the adjusting screw 62, so that the device can flexibly adjust the overall adaptation interval of the device, which can improve the overall adjustment and adaptation performance of the device. During the adjustment process, the support plate 55 slides on the inner side of the support frame 54 to assist in supporting and reinforcing the device with the linkage rod 643. After the adjustment is completed, the operating armrest 336 is released to reset the telescopic spring 333, and the limiting frame 335 can be pulled down and inserted into the inner side of the limiting hole 562 by the telescopic spring 333. At this time, the adjusting disk 32 can be locked and fixed, so that the overall device is easy to quickly adjust the use length.

[0029] By setting the mounting mechanism 5, the device can be used to push the linkage plate 563 to compress the return spring 564. At this time, the slide plate 53 with the viscous damper 4 is inserted into the inner side of the slide rail 52. When the slide plate 53 is completely immersed in the inner side of the slide rail 52, the restriction on the linkage plate 563 is cancelled, and the return spring 564 in the compressed state is reset to push the linkage plate 563 to rotate. The rotation of the linkage plate 563 can drive the movable rail 5651 to move, and the movable block 565 inside the movable rail 5651 is moved. 2 slides to provide reserved space, so that the limit pin 5653 can be inserted into the inner side of the limit hole 562. The limit pin 5653 now penetrates the limit hole 562 on the slide frame, and its end is inserted into the limit hole 562 on the slide plate 53. The slide plate 53 and the slide rail 52 are limited by the limit pin 5653, so that the viscous damper 4 can be stably installed on both ends of the purlin 1. If it is necessary to remove the viscous damper 4, it is only necessary to reversely rotate the adjustment mechanism 3 to cause the adjustment mechanism 3 to drive the screw rod 62 to reverse, and the screw rod 62 reverses. The linkage rod 643 and the first hinge seat 641 and the second hinge seat 642 can be driven to link with each other, and the linkage rod 643 pulls the side plate 51 to move inward, and during this period, the support plate 55 slides on the inner side of the support frame 54, and as the support plate 55 approaches the fixed plate 61, the push shaft 57 inside the support frame 54 can contact the outer end of the linkage plate 563, and the outer end of the linkage plate 563 can be pushed by the support shaft to cause the linkage plate 563 to rotate, and the rotation of the linkage plate 563 can drive the movable block 5652, the movable rail 5651 and the limit pin 5652 to rotate. 53 moves, causing the limit pin 5653 to disengage from the limit hole 562, and the limit of the limit pin 5653 between the slide plate 53 and the slide frame is lost, so that the slide plate 53 with the viscous damper 4 can be drawn out from the inner side of the slide groove. It can be seen that when the viscous damper 4 needs to be disassembled and assembled, the device only needs to adjust the telescopic mechanism 6 to the maximum contraction state, and the push shaft 57 can automatically push the linkage plate 563 to cause the limit pin 5653 to disengage, so that the device as a whole can quickly disassemble the viscous damper 4, thereby improving the convenience of overall operation and use of the device.
