Description

Technical Field

[0001] The invention relates to the technical field of rail welding, and more specifically to a movable welding climbing pad for a ballasted rail and a use method thereof. Background Art

[0002] With the increase in the operating time and transportation volume of existing lines in my country, rail wear is becoming more and more serious. In order to ensure the safe, stable, reliable and low-speed operation of railways, rail welding is an important link in laying seamless railway lines and an important guarantee for line driving safety.

[0003] At present, during on-site mobile welding, the size of the welding machine conflicts with the embedded iron seat structure of the ballasted track, so the welding machine cannot be directly placed for welding. The rails on both sides of the weld seam of the welded joint need to be raised to avoid interference with the embedded iron seat structure of the ballasted track when the welding machine is clamped. Lifting the rails on both sides of the welded joint to make the rails have a certain slope is called slope support. After the welding machine climbs the slope, the welding operation can be successfully completed.

[0004] There are two main ways to support rails along the slope in the existing technology. First, on-site personnel use wooden beams, round steel or steel plates with a certain height to support the bottom of the rails. This method is more arbitrary, the size of the support tools varies, the structural strength is unreliable, and it is difficult to achieve the horizontal and vertical limit fixation of the rails in the lifted state. There are safety hazards and the risk of the welding machine falling off the track and overturning; second, the pads in the existing technology use the sleeper bolts as a fixed reference to achieve the horizontal and vertical locking of the pads on the bearing rail groove. The pads of this technology are only suitable for ballasted track anchor bolt type line operations. Its size specifications are set based on the anchor bolts on the concrete sleeper bearing rail groove. It is not suitable for ballasted track rail mobile welding climbing operations with embedded iron seat fasteners.

[0061] Step 5. At this time, the rail mobile welding equipment moves to the support area to carry out rail welding operations. After the welding operation is completed, the welding equipment leaves the ballasted rail mobile welding climbing pad section.

[0062] It should be noted that: when construction work is carried out in the curved section, due to the superelevation of the curve between the two rails, the higher side is generally called the upper rail and the lower side is called the lower rail. When the sum of the height difference between the upper rail 50 and the lower rail 51 and the height of the first ballastless rail mobile welding climbing pad 52 is less than or equal to 120mm, the above operation steps are used for support, which will not affect the extension and retraction operation of the welding machine head of the rail mobile welding equipment, and can be used in conjunction with the gauge pull rod to reduce the risk of the rail mobile welding equipment falling off the track and overturning.

The first limiting bevel 20 and the second limiting bevel 23 are arranged relatively to each other, and the first bolt 10 and the second bolt 11 are tightened to make the first limiting bevel 20 fit on the bevel on one side of the bottom angle of the rail 45, and the second limiting bevel 23 fit on the bevel on the other side of the bottom angle of the rail 45, thereby limiting the bottom angle of the rail 45, realizing the horizontal and longitudinal limiting fixation of the rail in the lifted state and the movable welding climbing operation of the ballasted track rail with embedded iron seat fasteners.

[0064] like Figures 1 to 7 As shown, based on the same inventive concept, the present invention also provides a method for using a movable welded climbing pad for a ballasted rail, using the movable welded climbing pad for a ballasted rail described in any of the above embodiments to replace the upper rail of a curved section of a ballasted track line, comprising the following steps:

[0065] Step 1: Investigate the line conditions of the construction section, clarify the track type, fastener type, and determine the required support height;

[0066] Step 2: Determine the height of the height member 3 according to the height of the support pad required. Before construction, first install the first height plate 16 and the second height plate 17 between the upper mounting plate 15 and the lower mounting plate 12 in a relatively arranged manner, and place the first rail bottom angle pressing block 4 and the second rail bottom angle pressing block 5 on both sides of the upper body 1, and place them on the top surfaces of the first fixing block 13 and the second fixing block 14, respectively.

[0067] Step 3: on the side of the curved upper rail, remove the original fasteners of the curved upper rail, lift the curved upper rail in the vertical direction, use an electric hand tool to loosen the first bolt 10 and the second bolt 11, so that the first limiting inclined surface 20 and the second limiting inclined surface 23 are set back to back, and the corresponding first ballast rail mobile welding climbing pad 52 is placed on the sleeper bearing rail groove to ensure that the installation direction is correct; pass the first embedded iron seat fixing bolt 6 through the third installation hole 24 and the first hole on the first embedded iron seat, fasten the first embedded iron seat fixing nut 7 to the first embedded iron seat fixing bolt 6, pass the second embedded iron seat fixing bolt 8 through the fourth installation hole 25 and the second hole on the second embedded iron seat, and fasten the second embedded iron seat fixing nut 9 to the second embedded iron seat fixing bolt 8, thereby installing the first ballast rail mobile welding climbing pad 52 on the existing first embedded iron seat and the second embedded iron seat;

[0068] Step 4: put the curved upper rail in place, ensure that the rail bottom of the curved upper rail is on the top surface of the upper mounting plate 15, fit the first limiting inclined surface 20 on the first rail bottom angle pressing block 4 and the second limiting inclined surface 23 on the second rail bottom angle pressing block 5 on the inclined surfaces on both sides of the rail bottom angle of the curved upper rail 50 respectively, pass the first bolt 10 through the first mounting hole 18 and the first threaded hole 19 in sequence, and then threadably install it on the first fixing block 13, pass the second bolt 11 through the second mounting hole 21 and the second threaded hole 22 in sequence, and then threadably install it on the second fixing block 14, use an electric hand tool to tighten the first bolt 10 and the second bolt 11, and the double locking mechanism of the first ballast rail movable welding climbing pad 52 and the sleeper, and the rail and the first ballast rail movable welding climbing pad 52 can be realized;

[0069] Step 5. At this time, the rail mobile welding equipment moves to the support area to carry out rail welding operations.

The first ballasted rail mobile welding climbing pad 52 is lifted, and the first embedded iron seat fixing bolt 6, the first embedded iron seat fixing nut 7, the second embedded iron seat fixing bolt 8, and the second embedded iron seat fixing nut 9 are removed, and the first ballasted rail mobile welding climbing pad 52 is moved out of the sleeper bearing groove 47, and the curved upper rail is locked using the original fasteners of the line.

[0070] It should be noted that when the height difference between the upper curved rail 50 and the lower curved rail 51 and the height of the first ballastless rail mobile welding climbing pad 52 is less than or equal to 120 mm, the above operating steps are used for support, which will not affect the extension and retraction operation of the welding machine head of the rail mobile welding equipment. When used in conjunction with the gauge pull rod, the risk of derailment and overturning of the rail mobile welding equipment can be reduced.

[0071] In one embodiment of the present invention, the following steps are also included: Step 6, on the side of the curved lower rail 51, the original fasteners of the curved lower rail 51 are removed, the curved lower rail 51 is lifted in the vertical direction, and the corresponding second ballast rail mobile welded climbing pad 53 is placed on the sleeper bearing rail groove 47 to ensure that the installation direction is correct; use an electric hand tool to loosen the first bolt 10 and the second bolt 11, so that the first limiting inclined surface 20 and the second limiting inclined surface 23 are set back to back, and the corresponding second ballast rail mobile welded climbing pad 53 is placed on the sleeper bearing rail groove The groove 47 is placed on the bottom surface of the second embedded iron seat, and the second embedded iron seat fixing nut 9 is fixedly installed on the second embedded iron seat fixing bolt 8, thereby installing the second ballast rail mobile welding climbing pad 53 on the existing first embedded iron seat and the second embedded iron seat;

[0073] Step eight, at this time, the rail mobile welding equipment moves to the support area to carry out the rail welding operation. After the welding operation is completed, the welding equipment leaves the support section. At this time, the second ballasted rail mobile welding climbing pad 53 is removed, and the original first bolts 10 and second bolts 11 of the line are removed using electric hand tools, and the first rail bottom angle pressing block 4 and the second rail bottom angle pressing block 5 are removed.

[0074] It should be noted that: Figure 5 When there is superelevation on the curve, the height difference between the original upper rail and lower rail is H1. Figure 6 As shown, when the mobile welding operation is performed on the curved upper rail, the first ballastless rail mobile welding climbing pad 52 is used to support the curved upper rail 50 along the slope. After the support, the height difference between the rail heads of the curved upper rail 50 and the curved lower rail 51 is H2, H2=H1+h1, h1 is the height of the first ballastless rail mobile welding climbing pad 52, when the value of H2 is greater than 120mm, the extension and retraction of the welding machine head of the rail mobile welding equipment is limited, which is not conducive to the construction operation; Figure 7 As shown, when the mobile welding operation is performed on the curved upper rail 50, the first ballastless rail mobile welding climbing pad 52 is used to support the curved upper rail 50, and the second ballastless rail mobile welding climbing pad 53 is used to support the curved lower rail 51 along the slope at the same time. After the support, the height difference between the rail heads of the curved upper rail 50 and the curved lower rail 51 is H3, H3=H1+h1-h2, h2 is the height of the second ballastless rail mobile welding climbing pad 53, and by reasonably selecting the height of the second ballastless rail mobile welding climbing pad 53, the value of H3 is less than or equal to 120 mm, which can effectively avoid the limitation of the extension and retraction of the welding machine head of the rail mobile welding equipment, which is conducive to the construction operation.
