Embodiment Construction

[0026] Such as Figure 1-Figure 5 As shown, the rail row fixing frame of the present invention includes a longitudinal beam 1, a cross beam 2, a rail bottom slope fixing plate 3, a cross beam reinforcing rib 4, a longitudinal and cross beam connecting reinforcing rib 5 and a nut cover 6. Two longitudinal beams 1 and two cross beams 2 form a frame structure, which may be welded. A crossbeam reinforcing rib 4 is arranged in the middle of the two crossbeams 2, and rail bottom slope fixing plates 3 are arranged on both sides of the crossbeam reinforcing rib 4, and a total of four rail bottom slope fixing plates 3 are arranged on the two crossbeams 2, and two Two symmetrical. A pressure plate connection hole 15 is processed on the rail bottom slope fixing plate 3 , a longitudinal beam connection reinforcing rib 5 is arranged between the longitudinal beam 1 and the cross beam 2 , and a nut sleeve 6 is arranged in the middle of the longitudinal beam 1 .

Abstract

The invention provides a ballastless track construction device easy to fix the tight alignment result and insusceptible to external interference and a construction method thereof. The ballastless track construction device comprises working tracks, a dual-block sleeper and a track panel fixing frame of a framework structure, wherein the two working tracks are mounted on the track panel fixing frame to form a track panel framework; the two working tracks are parallel; and the track panel framework is mounted on the dual-block sleeper to form the framework type track panel. According to the invention, the track panel framework construction method is adopted, the conventional construction method is changed that the track panel is replaced by a track board; and then a mature board type adjusting process is adopted to adjust the track panel so that the tight alignment result is easy to fix, the device is insusceptible to external interference and the construction precision can be guaranteed.

Description

technical field [0001] The invention relates to a rail row fixing frame, in particular to a rail row fixing frame used for ballastless track construction. Background technique [0002] In the construction process of double-block ballastless track, the rough adjustment machine is generally used for the rough adjustment of the track row, but the equipment is expensive and bulky, and is not suitable for high-speed rail construction. If a total station plus a level is used for manual rough adjustment of the rail row, since one rail row has many screw support points on the ground, and each support point is mutually restricted, the rough adjustment efficiency and accuracy are difficult to meet the requirements. After the rough adjustment and fine adjustment are completed by the above two methods, the constraints on the rail array are very limited, and changes in the external environment will have a greater impact on the adjusted rail array, especially when pouring the integral tra...
