Embodiment 1

[0063] as attached Figure 11 As shown, an embodiment of a method for laying and replacing railway line components of the present invention specifically includes the following steps:

[0064] 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;

[0065] 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 (ie the roadbed), and the level of the truss 4 is adjusted. A flat cart 300 withdraw, as attached Figure 13 shown;

[0066] 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the new line component 500 placed on the second flat car 400 and transported below it, and the second flat car 400 is withdrawn, as shown in the appendix Figure 14 shown;

[0067] S104) The door hanging device ...

Embodiment 2

[0085] as attached figure 1 As shown, an embodiment of the door hanger 100 applied to the operation method for laying and replacing railway line components of the present invention described in Embodiment 1 specifically includes:

[0086] truss 4;

[0087] 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;

[0088]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 ...

Embodiment 3

[0099] as attached Figure 10 As shown, it is a schematic diagram of the transportation structure of the door hanging device 100 on the rail flat car described in Embodiment 2. The door hanging device 100 and the lifting platform 200 are both arranged on the first flat car 300, and the door hanging device 100 is further fixed on the lifting platform. 200, the lifting platform 200 has lifting and rotating functions. 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 l...

Abstract

The invention discloses a railway line component laying and replacing operation method. A gantry crane device is folded and fixed to a first flatcar to be transported to an operation site. And after arriving at the site, deploying a gantry crane device through a lifting platform arranged on the first flatcar, and withdrawing the first flatcar. And the gantry crane device lifts the new part placed on the second flatcar, and the second flatcar is withdrawn. And the gantry crane device transversely moves the new component to one side of the line, and transversely moves the old component to the other side of the line after hoisting the old component. And the gantry crane device hoists the new parts and transversely moves the new parts to the line, the old parts are hoisted, and the second flatcar drives in. And after the old part is placed on the second flatcar by the gantry crane device, the second flatcar is driven away. And the first flatcar drives in, the gantry crane device is recycled to the first flatcar through the lifting platform, the first flatcar drives away, and laying and replacing of the line components are completed. The technical problems that an existing line component replacement mode occupies the space of adjacent lines, safety risks exist, operation is not flexible, and operation requirements under the complex working conditions of railway lines are difficult to meet can be solved.

Description

technical field [0001] The invention relates to the technical field of railway construction machinery, in particular to an operation method for laying, replacing and hoisting railway line components. Background technique [0002] At present, the mileage of high-speed railways in my country has reached 35,000 kilometers, and the transport capacity has reached 70% of the total passenger traffic. Its normal operation has an increasing impact on national travel and business activities. Therefore, the on-site lifting, replacement and maintenance of high-speed rail line components has become the top priority of the technology in the field of track construction machinery line maintenance. At present, railway line components are mainly lifted and replaced by rail cranes and cantilever crane equipment. For the replacement of long and heavy line components, such as steel rails, pointed rails, turnouts and other components, when multiple rail cranes are used for operation, it is often...
