Height-adjustable anti-seismic spherical steel support for rail transit
A height-adjustable anti-seismic spherical steel support for rail transit comprises an upper support plate assembly, a middle support plate assembly, a lower support plate assembly, an anchoring assembly, a height adjusting device and a protective device, wherein the lower support plate assembly on the lower portion is connected with an abutment through an anchor bolt assembly, and the upper support plate assembly on the upper portion is connected with a beam body through the height adjusting device. The height adjusting device can comprise an upper sleeve, a pressing block and an anchor rod,wherein the lower portion of the upper sleeve is embedded into a beam bottom embedded plate, a plurality of annular grooves are formed in the inner wall of the upper sleeve at intervals, and a plurality of conical grooves are correspondingly formed in the upper surface of the anchor rod and the lower surface of the pressing block respectively. Each pair of oppositely arranged conical grooves forma conical space for respectively placing a pressing ball, and each pressing ball is embedded into the corresponding groove to form expansion and fixation so as to transmit the axial force of the anchor rod; therefore, the problems that the height of an existing height adjusting support is increased due to increase of the height adjusting amount, the economy is poor, the operation efficiency is low, the durability of a protection device is poor, and maintenance is inconvenient can be effectively solved, and height adjusting of the support is convenient, the economy is good, and the height adjusting operation efficiency is remarkably improved.
一种轨道交通用可调高抗震球型钢支座，包括上座板组合、中座板组合、下座板组合、锚固组件、调高装置和防护装置，下部的下座板组合通过锚栓组件与墩台相连，上部的上座板组合通过调高装置与梁体相连，所述调高装置可包含上套筒、压块和锚杆，所述上套筒的下部嵌入梁底预埋板，所述上套筒的内壁上间隔设有多道环形的凹槽，所述锚杆的上表面和压块的下表面分别对应设有多个锥形槽，每对相对设置的锥形槽形成一锥形空间以分别放置压球，各压球嵌入凹槽形成胀紧并固定以传递锚杆的轴向力；由此，本发明能有效解决现有调高支座因调高量增加支座高度增加，经济性差，作业效率低、防护装置耐久性差、维护不方便等问题，实现支座的调高方便，经济性好，调高作业效率显著提高。
