Embodiment Construction
[0009] Ballastless track adjustment device for super high section of high-speed railway base, such as figure 2 As shown, the fixed plate 1 is included, and the fixed plate 1 is fixedly installed on the ground. A fixed seat 2 is installed on the fixed plate 1, and a vertical limit hole 3 is provided on the fixed seat 2, and a leading screw 4 is arranged in the limit hole 3. The limiting hole 3 plays a role of limiting the leading screw 4 to prevent the leading screw 4 from tilting under force. The lower end of the lead screw 4 is installed on the fixed plate 1 through a bearing, and a limit plate 5 is arranged on the fixed seat 2. The bottom surface of the limit plate 5 is in contact with the fixed seat 2. One end of the limit plate 5 is provided with a chute 6, and the limit plate 5 The other end is connected to the lower part of the ballastless track formwork, the lead screw 4 is located in the chute 6, the side walls on both sides of the chute 6 are provided with threads, ...

Provided is a high-speed rail subgrade superhigh section ballastless track adjusting device. The device comprises a fixing plate, a fixing base is installed on the fixing plate, a vertical spacing hole is arranged on the fixing base, a lead screw is arranged in the spacing hole, the lower end of the lead screw is installed on the fixing plate through a bearing, the fixing base is provided with a spacing plate, the bottom surface of the spacing plate contacts with the fixing base, one end of the spacing plate is provided with a sliding groove, and the other end of the spacing plate is connected with the lower part of a ballastless track template, the lead screw is in the sliding groove, side walls on two sides of the sliding groove are provided with threads, the sliding groove is cooperated with the lead screw, the lower part of the lead screw is provided with a wheel disk, the fixing base is provided with a cavity, the cavity is communicated with the spacing hole, the wheel disk is in the cavity, and the wheel disk is connected with a power device through a driving belt. The device is advantaged in that a method that the lead screw and the sliding groove on the spacing plate are cooperated is used, through rotating the lead screw, transverse movement of the spacing plate can be controlled, so as to adjust after a track section has transverse displacement, thereby preventing from influencing fine adjustment speed.
Description
technical field [0001] The invention relates to a track adjusting device, in particular to a ballastless track adjusting device for a super-high section of a high-speed railway. Background technique [0002] The structural height of the ballastless track in the ultra-high section of the high-speed railway foundation is fixed at 815mm. When the subgrade has a superelevation curve, the subgrade support layer is inclined on the subgrade bed, and the fine adjustment of the ballastless track is performed on this inclined surface. When adjusting the rail direction adjuster, affected by the inclination angle, the rail row will produce lateral displacement during the adjustment process. When concrete is poured, it will also produce lateral displacement when it is subjected to the external force of concrete pouring and vibrating rod vibration. The centerline and elevation of the ballastless track will change greatly and need to be readjusted, thus affecting the fine adjustment speed...
