Embodiment 1
[0063] as attached figure 1 As shown, an embodiment of the door hanging device 100 for laying and replacing railway line components of the present invention specifically includes:
[0064] truss 4;
[0065] It is arranged on the truss 4 and can be carried out laterally along the truss 4 (as attached figure 1 The traverse travel mechanism 8 that moves in the direction shown in W) to adjust the hoisting position; the traverse travel mechanism 8 includes a lifting mechanism 7, and the lifting mechanism 7 can drive the chain 16 to lift and move vertically, and the end of the chain 16 is set There is a hook 6, and the hook 6 is further connected with a spreader 700, and is clamped by the spreader 700 to realize the transportation of railway line components;
[0066] The left and right legs are respectively movably arranged on the lower parts of the left and right ends of the truss 4 , and the left and right legs can move laterally along the truss 4 to adjust the lateral span of t...
Embodiment 2
[0077] as attached Figure 10 As shown, it is a schematic diagram of the transportation structure of the door hanger 100 of the present invention described in Embodiment 1 on the rail flat car. On the lifting platform 200, the lifting platform 200 has functions of lifting and rotating. A new line component 500 for replacement is placed on the second flat car 400 . The door hanger 100 placed on the first flat car 300 and the new line component 500 placed on the second flat car 400 are transported to the construction area by the rail car 1000 powered. After arriving at the designated construction area, the door hanging device 100 places the outriggers on both lateral sides of the door hanging device 100 with the specified designation of the roadbed 900 on both sides of the basic rail 800 of the line through the lifting and rotating actions of the lifting platform 200 on the first flat car 300 . area.
Embodiment 3
[0079] as attached Figure 11 As shown in the figure, an embodiment of the operation method of the door hanging device for laying and replacing the railway line components of the present invention as described in Embodiment 1 specifically includes the following steps:
[0080] S101) The door hanger 100 retracts the left and right legs, and is fixed on the first flat car 300 and transported to the work site, as shown in the attached Figure 12 shown;
[0081] S102) After arriving at the construction site, deploy the door hanging device 100 through the lifting platform 200, the left and right outriggers of the door hanging device 100 are extended and supported to the working surface 900, the horizontality of the truss 4 is adjusted, the first flat car 300 withdraw, as attached Figure 13 shown;
[0082] S103) The door hoisting device 100 hoists the new line component 500 placed on the second flat car 400 and transported below it, and the second flat car 400 is withdrawn, as s...
