Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail welding, and more particularly to a ballast type rail mobile welding climbing pad and a use method. BACKGROUND

[0002] With the increase of the operation time of existing lines and the continuous increase of the traffic volume in China, the rail wear is becoming more and more serious. In order to ensure the safe, stable and reliable operation of the railway, rail welding is an important link for laying seamless lines and an important guarantee for the safety of line operation.

[0003] At present, when the mobile welding operation is carried out on site, the welding machine cannot be directly positioned and welded due to the conflict between the size of the welding machine and the embedded iron seat structure of the ballast track. The rails on both sides of the welded joint need to be lifted to avoid interference between the welding machine clamping and the embedded iron seat structure of the ballast track. Lifting the rails on both sides of the welded joint causes a certain slope of the rails, which is called slope supporting pad. After the welding machine climbs the slope, the welding operation can be successfully completed.

[0004] There are two main ways to support the rails on the slope in the prior art. First, the on-site personnel use wooden frames, round steels or steel plates with a certain height to support the rails. This method is relatively arbitrary, and the size and specification of the supporting tools are different, and the structural strength is unreliable. It is difficult to achieve the horizontal and vertical limiting and fixing of the rails in the lifted state, and there is a safety hazard, which may cause the welding machine to fall off and overturn. Second, the existing pad uses the sleeper bolt as a fixed reference to realize the horizontal and vertical locking of the pad on the bearing rail groove. This technology pad is only suitable for the anchor bolt type line operation of the ballast track, and the size and specification of the pad are set based on the anchor bolt on the bearing rail groove of the concrete sleeper, which is not suitable for the embedded iron seat fastener type ballast track rail mobile welding climbing operation.

Pass the second bolt through the second mounting hole and the second threaded hole in sequence and then thread it onto the second fixing block. Tighten the first and second bolts using a power hand tool. This achieves a dual locking mechanism between the ballasted rail moving welded climbing pad and the sleeper, and between the rail and the ballasted rail moving welded climbing pad. Step 5: At this point, the rail mobile welding equipment moves to the support area and performs rail welding operations. After the welding operation is completed, the welding equipment leaves the section of the ballasted rail mobile welding ramp block. Then, the ballasted rail mobile welding ramp block is removed. Using power tools, the original first and second bolts of the line are removed, and the first and second rail bottom corner blocks are removed. The supported rail is lifted, and the first embedded iron seat fixing bolt, the first embedded iron seat fixing nut, the second embedded iron seat fixing bolt, and the second embedded iron seat fixing nut are removed. The ballasted rail mobile welding ramp block is moved out of the sleeper bearing groove, and the supported rail is locked using the original fasteners of the line.

12. A method of using a movable welded climbing pad for ballasted rails, comprising using the movable welded climbing pad for ballasted rails as described in any one of claims 1-10 to replace the upper rail of a curved section of a ballasted track, characterized in that, Includes the following steps: Step 1: Investigate the track conditions of the construction section, identify the track type and fastener type, and determine the required support height; Step 2: Determine the height of the height component according to the required support height. Before construction, install the first height plate and the second height plate opposite to each other between the upper mounting plate and the lower mounting plate. Place the first rail bottom corner pressure block and the second rail bottom corner pressure block on both sides of the upper body, and place them on the top surfaces of the first fixing block and the second fixing block respectively. Step 3: On the side of the curved upper rail, remove the original fasteners of the curved upper rail, lift the curved upper rail vertically, and use a power hand tool to loosen the first and second bolts so that the first and second limiting inclined surfaces are set opposite to each other. Place the corresponding first ballasted rail movable welded climbing pad on the sleeper bearing groove, ensuring the correct installation direction. Pass the first pre-embedded iron seat fixing bolt through the third mounting hole and the first hole on the first pre-embedded iron seat, and tighten the first pre-embedded iron seat fixing nut on the first pre-embedded iron seat fixing bolt. Pass the second pre-embedded iron seat fixing bolt through the fourth mounting hole and the second hole on the second pre-embedded iron seat, and tighten the second pre-embedded iron seat fixing nut on the second pre-embedded iron seat fixing bolt, thereby installing the first ballasted rail movable welded climbing pad on the existing first and second pre-embedded iron seats. Step 4: Position the upper rail, ensuring the bottom of the upper rail is on the top surface of the upper mounting plate. Place the first limiting inclined surface on the first rail bottom corner pressure block and the second limiting inclined surface on the second rail bottom corner pressure block onto the two inclined surfaces of the bottom corner of the upper rail. Pass the first bolt through the first mounting hole and the first threaded hole in sequence and then thread it onto the first fixing block. Pass the second bolt through the second mounting hole and the second threaded hole in sequence and then thread it onto the second fixing block. Tighten the first bolt and the second bolt using an electric hand tool. This will achieve a double locking mechanism between the first ballasted rail moving welded climbing pad and the sleeper, and between the rail and the first ballasted rail moving welded climbing pad. Step 5: At this point, the rail mobile welding equipment moves to the support area and performs rail welding operations. After the welding operation is completed, the welding equipment leaves the support section. Then, the first ballasted rail mobile welding ramp block is removed. Using power tools, the original first and second bolts of the line are removed. The first and second rail bottom corner blocks are removed. The upper curved rail is raised. The first embedded iron seat fixing bolt, the first embedded iron seat fixing nut, the second embedded iron seat fixing bolt, and the second embedded iron seat fixing nut are removed. The first ballasted rail mobile welding ramp block is moved out of the sleeper bearing groove. The upper curved rail is locked using the original fasteners of the line.

The method of using the movable welding ramp pad for ballasted steel rails according to claim 12, characterized in that, It also includes the following steps: Step Six: On the side of the curved lower rail, remove the original fasteners of the curved lower rail, lift the curved lower rail vertically, and place the corresponding second ballasted rail movable welded climbing pad on the sleeper bearing groove, ensuring the correct installation direction; use a power hand tool to loosen the first and second bolts, so that the first and second limiting inclined surfaces are set opposite to each other, and place the corresponding second ballasted rail movable welded climbing pad on the sleeper bearing groove, ensuring the correct installation direction; pass the first pre-embedded iron seat fixing bolt through the third mounting hole and the first hole on the first pre-embedded iron seat, and tighten the first pre-embedded iron seat fixing nut on the first pre-embedded iron seat fixing bolt; pass the second pre-embedded iron seat fixing bolt through the fourth mounting hole and the second hole on the second pre-embedded iron seat, and tighten the second pre-embedded iron seat fixing nut on the second pre-embedded iron seat fixing bolt, thereby installing the second ballasted rail movable welded climbing pad on the existing first and second pre-embedded iron seats; Step 7: Position the lower curved rail, ensuring the bottom of the lower curved rail is on the top surface of the upper mounting plate. Place the first limiting inclined surface on the first rail bottom corner pressure block and the second limiting inclined surface on the second rail bottom corner pressure block onto the two inclined surfaces of the bottom corner of the lower curved rail, respectively. Pass the first bolt through the first mounting hole and the first threaded hole in sequence and then thread it onto the first fixing block. Pass the second bolt through the second mounting hole and the second threaded hole in sequence and then thread it onto the second fixing block. Tighten the first and second bolts using a power hand tool. This will achieve a double locking mechanism between the second ballasted rail moving welded climbing pad and the sleeper, and between the rail and the second ballasted rail moving welded climbing pad. Step 8: At this point, the rail mobile welding equipment moves to the support area and performs rail welding operations. After the welding operation is completed, the welding equipment leaves the support section. Then, the second ballasted rail mobile welding ramp block is removed. The original first and second bolts of the track are removed using power tools. The first and second rail bottom corner blocks are removed. The lower curved rail is lifted.
