Description

Technical Field

[0001] This utility model relates to a steel ball bearing, and more particularly to a unidirectional movable space frame shock-absorbing steel ball bearing, belonging to the technical field of spherical bearings. Background Technology

[0002] Based on the structure of the project and the performance characteristics of the supports, steel structure supports are classified into four types: GKGZ type seismic-resistant steel ball bearings, GJGZ type damping steel ball bearings, GKQZ type seismic-resistant spherical steel bearings, and GJQZ type damping spherical steel bearings. Unidirectional movable space frame damping steel ball bearings are an important support mechanism used to support and fix space frame steel structures and bear various loads.

[0003] The "Energy-dissipating and vibration-damping spherical support" disclosed in application number "201921345776.1" "includes a lower support plate, a vibration-damping device, a limiting plate, a support steel ball core, and an upper support. The support steel ball core is fixedly installed on the top of the lower support plate, and the upper support is placed on the top of the support steel ball core. The bottom edge of the upper support is stuck on the top edge of the lower support plate, and the vibration-damping device is fixedly installed between the bottom circumference of the upper support and the lower support plate." In this utility model, when the spherical support is subjected to external force, the vibration-damping device works together with the support steel ball core to dissipate energy and reduce vibration, which can significantly consume external force and effectively improve the energy dissipation and vibration reduction effect of the spherical support. The energy-dissipating and vibration-damping spherical support is provided with a limiting plate. The connecting rod on the limiting plate is fixedly connected to the upper support. When the upper support slides up and down under external force, the slider slides up and down with the upper support in the groove, which can limit the upper support and prevent the upper support from rotating when sliding up and down.

[0004] However, the above method still has the following drawbacks: the shock-absorbing device welded between the upper and lower seats is used in conjunction with the spherical seat to absorb energy and reduce vibration; however, since multiple shock-absorbing devices are firmly connected between the upper and lower seats by welding, once the shock-absorbing device fails or its performance deteriorates due to long-term use or other factors, it becomes extremely difficult to disassemble and repair it individually, and more complex and costly measures may be required. Utility Model Content

[0005] The purpose of this utility model is to provide a unidirectional movable space frame shock-absorbing steel ball support to solve the problem mentioned in the background art that multiple shock-absorbing devices are firmly connected between the upper and lower seats by welding. Once they fail or their performance deteriorates due to long-term use or other factors, it is extremely difficult to disassemble and repair them individually, and complex and costly measures are often required.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a unidirectional movable space frame shock-absorbing steel ball support, comprising a base, a base plate slidably disposed at the bottom end of the inner wall of the base, a fixed seat fixedly disposed at the middle of the top end of the base plate, a top seat engaged at the top of the fixed seat, a steel ball core disposed at the middle of the top end of the fixed seat, a plurality of evenly spaced sliders slidably disposed on both sides of the top end of the base plate, and a buffer assembly disposed at the top end of the sliders, a plurality of bolts I threadedly connected to both sides of the base plate, a threaded hole I threadedly connected to the bolt I on one side of the slider, a plurality of bolts II threadedly connected to both sides of the top end of the top seat, and mounting assemblies disposed on both sides of the top end of the base plate.

[0008] As a preferred technical solution of this utility model, the top two sides of the base plate are provided with sliding grooves that cooperate with the slider, and the two sides of the base plate are provided with operating grooves corresponding to the bolts.

[0009] As a preferred embodiment of this utility model, a first polytetrafluoroethylene plate is fixedly provided at the top of the steel ball core, a second polytetrafluoroethylene plate is fixedly provided at the bottom of the steel ball core, and a steel plate is provided at the middle of the bottom of the top seat.

[0010] As a preferred embodiment of this utility model, the buffer assembly includes a cylinder, which is fixedly installed on the top of the slider. A movable rod is slidably provided inside the cylinder, and a circular plate is fixedly provided at the bottom end of the movable rod. A buffer spring is fixedly provided at the bottom end of the circular plate, and the bottom end of the buffer spring is fixedly connected to the bottom end of the inner wall of the cylinder.

[0012] As a preferred technical solution of this utility model, the mounting assembly includes a mounting plate, which is fixedly installed on one side of the top of the base plate. The top of the mounting plate is provided with a plurality of evenly spaced bolts, and both sides of the top of the base are provided with threaded holes for threaded connection with the bolts.

[0013] As a preferred embodiment of this utility model, a fixing plate is fixedly provided at the bottom of both sides of the top seat, and a shock absorber is provided between the fixing plate and the bottom plate.

[0014] Compared with related technologies, the unidirectional movable space frame shock-absorbing steel ball support provided by this utility model has the following beneficial effects:

[0015] 1. With the help of the set mounting components, along with the mounting plate and bolt three, the mounting plate and base plate can be easily disassembled. At the same time, through the synergistic action of the buffer component and bolts one and two, the disassembly process of the buffer component is also made simpler. In this way, when the buffer component fails or its performance deteriorates due to long-term use or other factors, there is no need to take more cumbersome and costly repair measures. Instead, it can be directly disassembled and repaired separately, thereby effectively reducing maintenance costs and achieving economical and efficient operation and maintenance management.

[0016] 2. Through the configured buffer components, the displacement generated inside the cylinder by the moving rod causes the buffer spring to apply force in the vertical direction. Combined with the shock absorber, it can work together with the steel ball core to implement efficient energy dissipation and vibration reduction measures for the space frame structure, thereby ensuring the stability of the movable space frame structure.

Then, using the mounting holes 18 on the support plate 17 and 19 on the top seat 4, and with the relevant fasteners, install the shock-absorbing steel ball support to the one-way movable space frame for support and fixation. Through the set buffer component 6 combined with the top seat 4, the moving rod 602 can be squeezed, so that the moving rod 602 and the circular plate 603 can move synchronously. Combined with the buffer spring 604 and the design of the shock absorber 21, it can work together with the steel ball core 9 to implement efficient energy dissipation and shock absorption measures for the space frame structure, thereby ensuring the stability of the movable space frame structure.

[0033] When the buffer assembly 6 malfunctions or its performance deteriorates due to long-term use or other factors, it needs to be disassembled or replaced for maintenance. First, use the tools to remove the fasteners at mounting holes 18 and 19 to facilitate the disassembly of the shock-absorbing steel ball support. Then, use bolt 1102 and screw hole 1103 to remove bolt 1102, making it easier to remove the mounting plate 1101 and base plate 2 from the inside of the base 1. Next, use the operating groove 15 to remove bolt 7, allowing the slider 5 to be disassembled. Then, use the moving groove 16 to remove bolt 8, freeing the moving rod 602. Finally, use the moving groove 16 and operating groove 15 to disassemble the shock-absorbing device, effectively reducing maintenance costs. Finally, repeat the above steps to reinstall the repaired shock-absorbing device.
