[0029] Example 2: Such as Figure 5 As shown, the movable-center rail switch replacement hoisting car includes a rail car 1, a fixed gantry flat car 2 and a movable gantry flat car 3 connected end to end in turn by hooks 16. The overall structure is the same as that of Embodiment 1, but is different The point is that the fixed gantry flat car 2 consists of two fixed gantry component flat cars 2-1, and the bottom of each fixed gantry component flat car 2-1 is vertically equipped with hydraulic telescopic support arms 19; The fixed gantry component flat car 2-1 at the end is fixed with a fixed gantry small flat car track 6; the fixed gantry 4 and the fixed gantry flat car support frame 5 are placed at the end of the fixed gantry component flat car 2-1 The top of the rear of the car.
[0030] The movable gantry flat car 3 is composed of two movable gantry component flat cars 3-1. Each movable gantry component flat car 3-1 is vertically equipped with hydraulic telescopic support arms...
Example Embodiment
[0031] Embodiment 3: A method for replacing long and heavy parts of high-speed railway turnouts, which includes the following steps:
[0032] Step 1. The long and heavy parts of the new high-speed railway turnout are hoisted and fixed: Image 6 As shown, in the rail material storage yard, the new high-speed rail turnout long and heavy parts 17 are hoisted on the movable gantry flat car 3 with lifting equipment, and the movable gantry flat car 9 and the movable gantry flat car 9 on the movable gantry flat car track 8 are used. The gantry flat car support frame 12 jointly supports the long and heavy parts 17 of the new high-speed railway turnouts, and the long and heavy parts 17 of the new high-speed railway turnouts are bound and fixed on the movable gantry small flat car 9 and the movable gantry flat car support frame 12 according to relevant specifications.
[0033] Step 2. Unfold and fix the fixed gantry flat car and the movable gantry flat car: such as Figure 7 As shown, when th...
