Correct installation and regular maintenance room steel ball bearings to ensure that important measure seismic work properly. The work at the factory, the general should be clearly labeled, indicating the bearing type, reaction force, displacement and rotation, in order to avoid confusion in the installation is. Usually bearing the whole factory assembled after transport to the site, in order to ensure the integrity of the seat during transport, the application temporarily positioning device to connect the various parts of the stand, these temporary seat positioning device before it is work to be demolition, concrete demolition time, site engineering and technical personnel should be based on the form and structure bearing stress conditions. Before bearing installation, the installation position of the carriage should be measured testing, production and installation of a sliding bearing or a plane to be parallel to the rolling plane, which is parallel to the degree of tolerance of not more than 2%. Seismic steel ball bearing installation bearing top, the relative position of the floor response activities before testing. Preset amount of displacement roller bearings and plain bearings must meet the design requirements. When restricted bearing installation temperature preset amount of displacement of the slide bearing must be adjusted, should be adjusted to work under the guidance of the displacement bearing professional engineer. After the seismic steel ball bearing installation, rolling and sliding plane should be level. Tilt with the theory of plane is not more than 2%, the upper and lower bearing plate center in response, the deviation is not more than 2%. Stone bearing pad design should be considered in the low beams and piers between the top surface and leave some headroom for inspection and maintenance at bearing use, and if necessary, can be placed jack, bearing replacement. In the railway bridge in 2003 and issued special structures, design rules, and also raised seat height adjustment can be used parallel to the plane of the plate (plate) to achieve. Simple seismic steel ball bearing structure, the increase in low cost, can increase or decrease the seat height as needed, but it must be raised when jacking beams. Spiral raised this way increase the way of raw ball bearings, Railway Research Institute for Aviation Rocket Sled height adjustable rails project on seismic steel ball bearings in 1987, this approach increases the bearing larger trapezoidal screwed ball bearing manufacturers design novel, and after raising universal threaded ball bearing superior quality, on, the gap between the lower screw, and use the grouting filling, increase the process also requires jacking beams. Ways to increase the pressure injection of rubber bearings after installation by pressure injection of rubber to increase seismic steel ball bearings with grouting pipes bearing on the floor, you can increase the pressure inside the bearing pressure injection through the rubber sheet rubber thickness, thereby adjusting the seat height. Steel ball bearings to increase the seismic design was novel, when raised without a separate jacking beams, by setting the multi-channel pressure injection holes can increase several times. Such a large number of ways to increase the use of the Beijing-Tianjin intercity railway. Because raising process requires roof beams, construction measures are more complicated and seismic steel ball bearings have no need to set up another way to raise the jack, you can use the advantages of the top beam bearing itself, and can achieve stepless increase, simple construction measures.
