Problems solved by technology
[0013] The technical problem to be solved by the present invention is to provide an overall longitudinal movement device and method for railway turnouts. When the railway turnout is moved vertically and the simple rail is used, it takes a long time to erect and dismantle the skylight, which will easily cause construction delays.

Embodiment Construction
[0039] like figure 2 and image 3 As shown in the figure, an overall longitudinal movement device for railway turnouts, 5 to 15 pairs of longitudinally moving flat cars 3 are arranged below the turnout sleeper 2 to be moved, and are arranged along the straight line direction of the turnout rail 1, and the length of each pair of longitudinally moving flat cars 3 The spacing is less than the minimum length of the turnout sleepers 2 passing through it, and the lower surface of each longitudinal moving flat car 3 is seated on the slotted bed 5 through wooden sleepers 4; wherein the longitudinal moving flat car 3 is composed of a support 11 and a rolling device 10 Composition, and the rolling end surface of the rolling device 10 protrudes from the upper surface of the support 11.
[0040] like Figure 4 and Figure 5 As shown, the first structural embodiment of the longitudinal moving flat car 3: the rolling device 10 is composed of several roller cylinders 15 arranged in paral...

The invention relates to an overall longitudinal movement device for a railway turnout. The device is characterized in that 5-15 pairs of longitudinal movement flat cars are arranged below to-be-moved turnout sleepers and arranged in the linear direction of turnout rails, and the lower surface of each longitudinal movement flat car is located on a grooved foundation bed directly or through a wooden sleeper; each longitudinal movement flat car comprises a support and rolling devices, and rolling end surfaces of the rolling devices bulge out of the upper surface of the support. The longitudinal movement device is reasonable in design, light to use, time-saving, labor-saving, safe and reliable; a longitudinal movement method can fundamentally solve the problem of high probability of construction delay due to longer skylight time occupied by erection and dismounting when simple rails are used for conventional longitudinal movement of the railway turnout.
Description
technical field [0001] The invention relates to an overall longitudinal movement device of a railway turnout and a longitudinal movement method thereof, belonging to small-scale railway machinery equipment. Background technique [0002] There are two methods for railway turnout / rail replacement: horizontal movement and longitudinal movement. In the electrified railway section, due to the limitation of catenary pillars and other obstacles, the longitudinal shifting method is more common, that is, a simple track is built with steel rails at the pre-inserted turnout / rail row and connected to the existing line, and the switch / rail row is the same Put pulleys between the rails of the existing line, push the turnout / rail row to move longitudinally along the simple track, then use the switch re-laying unit to erect the turnout / rail row, withdraw the pulley and simple track, put the pulley down and drop the turnout / rail row to align Carry out longitudinal fine adjustment of the tur...
