Problems solved by technology

[0002] When stabilizing and maintaining railway lines, it is inevitable to encounter the main line and turnouts. At present, the general stabilizer car does not have the function of stabilizing the turnouts. It can only stabilize the main line. After passing through the turnout area, the main line is stabilized. In the past, the railway turnouts could only be maintained occasionally by using the original manual method. In order to quickly improve the lateral resistance and overall stability of the turnout, and create Conditions, need a kind of main line turnout stabilizing car that can stabilize the main line and the turnout to carry out continuous and uninterrupted stable operation of the railway line construction machinery and simple operation and construction method
[0003] The Chinese patent application with the application number 201210159590.3 discloses a line tamping stabilization vehicle and a method for stabilizing a turnout. Efficient stepping and tamping stabilization operations, but there is no specific method on how to control the stabilization operations in the turnout area and how to construct them

Embodiment 11

[0069] Example 1.1 : A construction method for the main line turnout stabilization vehicle operation, which includes dividing the main line turnout section into five stages, such as figure 1 As shown, that is, stage Ⅰ: normal line operation stage before the turnout, stage Ⅱ: unilateral rail clamping stage of the point switch part, stage Ⅲ: normal line operation stage of the connecting part, stage Ⅳ: single-sided rail clamping stage of the frog part Side rail clamping stage, stage Ⅴ: the normal main line operation stage after the turnout is out.

[0070] The overall construction plan of the operation is as follows: ① Put down the stabilizing device in the main line section, start the main line stabilization operation, and work all the way to the turnout area in the direction of the switch center; ② After changing the control mode, continue the stabilization of the three different parts of the turnout area. Operation; ③ After stabilizing the turnout, enter the main line to con...

Embodiment 12

[0106] Example 1.2 : a kind of main line turnout stabilizing car operation construction method, with embodiment 1.1, difference is: in the present embodiment, the main line turnout stabilizing car in the stable operation control method of turnout area comprises preparatory stage, the 1st step, the 2nd Step 1, step 3, step 4, and step 5, which are carried out in sequence according to the order of preparation stage, step 1 to step 5. in:

[0107] Preparation stage: In the main line section, put down each measuring trolley, then pull the lift switch of the stabilizer device and unlock it, lower the stabilizer device on the rail, and first control the piston rod Ⅰ at one end of the 20mm stroke of the four horizontal rail support cylinders through the oil circuit The piston rod II at the end of the 15mm stroke is fully retracted, so that the distance between the rollers on the two rails is the minimum value of 1420mm at this time;

[0108] Step 1: Supply oil to the oil circuits ...

Embodiment 21

[0115] Example 2.1 : a method for controlling the stability of the main line turnout stabilization vehicle in the turnout area, the same as embodiment 1.2, the difference is that after the steps of embodiment 1.2 are performed, when the next group of turnouts is encountered, the switch will Repeat steps 2, 3, and 4 in sequence.

Abstract

An operation construction method of a main-line turnout stabilizing carriage comprises the step that a main-line turnout zone is divided into five stages, namely the stage I of normal main-line operation before turnout, the stage II of single-side rail clamping of a trip switch part, the stage III of normal main-line operation of a connection part, the stage VI of single-side rail clamping of a frog part, and the stage V of normal main-line operation after a train drives out of the turnout zone. The operation construction method researches the stable operation procedure and the construction mode of the main-line turnout stabilizing carriage in the main line and the turnout zone. A folding and unfolding stabilizing device is used in a main-line section, stabilizing operation of the main line and the turnout zone can be conducted continuously without being stopped by switching operation modes, and time is saved. Meanwhile, turnout operation has the specificity different from main line operation.

Description

technical field [0001] The invention relates to a method for stabilizing a main line turnout of a railway rail, in particular to a construction method for a main line turnout stabilization vehicle. Background technique [0002] When stabilizing and maintaining railway lines, it is inevitable to encounter the main line and turnouts. At present, the general stabilizer car does not have the function of stabilizing the turnouts. It can only stabilize the main line. After passing through the turnout area, the main line is stabilized. In the past, the railway turnouts could only be maintained occasionally by using the original manual method. In order to quickly improve the lateral resistance and overall stability of the turnout, and create Conditions, need a kind of not only can stabilize main line, but also the main line turnout stabilizing car that can stabilize turnout continuously and uninterruptedly implement the construction machine and the simple operation construction meth...
