[0059] 1 to 9 , an embodiment of the present invention provides a method for replacing a track plate 100 , and the method for replacing a track plate 100 includes:

[0060] S100, lifting the rail 200 arranged on the track plate 100 to be replaced;

[0061] S200, lifting the track plate 100 to be replaced until it is separated from the base plate 300;

[0062] S300, moving the track plate 100 to be replaced horizontally to an open space between two adjacent tracks, and transporting it out of the open space;

[0063] S400, transporting a new track plate 100 to the area to be replaced, and placing the track plate on the base plate and returning it to its original position;

[0064] S500 , installing the rail 200 onto the new track plate 100 .

[0065] The present technical solution provides a method for replacing a track plate 100, by lifting the rail 200 set on the track plate 100 to prevent the rail 200 from being deformed when the track plate 100 is lifted. The track plate 100 to be replaced is lifted to be separated from the base plate 300, so that the track plate 100 can be smoothly translated relative to the base plate 300, thereby moving the track plate 100 to be replaced out to make way for a new track plate 100. The track plate 100 to be replaced is translated to the open space between two adjacent tracks, and then transported out of the open space to clear the open space between two adjacent tracks. The new track plate 100 is transported to the area to be replaced, and the track plate is placed back in place on the base plate so that the rail 200 is supported by the new track plate 100. Finally, the rail 200 is installed on the new track plate 100 to complete the repair of the entire track. Through the above steps, the track plate 100 with cracks can be replaced while ensuring that the rail 200 is not damaged, thereby ensuring the safe operation of the entire track.

[0066] It should be noted that, in the present embodiment, the base plate 300 is supported on the foundation, the track plate 100 is fixedly connected to the base plate 300, and the rail 200 is fixedly connected to the track plate 100. Two limiting grooves 310 spaced apart along the length direction of the base plate 300 are provided on the base plate 300, and two limiting protrusions 110 spaced apart are provided on the track plate 100. Both the limiting grooves 310 and the limiting protrusions 110 extend along the width direction of the track. A track is used for a train to run in one direction, and two parallel rails 200 are provided on the track. It should be understood that each rail 200 is formed by connecting multiple sections of rails 200. Further, a section of rail 200 is provided with multiple track plates 100 along its length direction. For example, four track plates 100 are provided below a section of rail 200.

[0067] Specifically, two rows of rail supports 120 are arranged at intervals along the width direction of the track plate 100 on the track plate 100. The two rows of rail supports 120 are arranged at intervals along the width direction of the track plate 100. The rails 200 are supported on the rail supports 120, and the rail fasteners on the rails 200 are fixedly connected to the rail supports 120.

[0068] In one embodiment, as shown in FIG1 , before lifting the rail 200 disposed on the track plate 100 to be replaced, the process further includes:

[0069] S010, removing all the rail 200 fasteners on the rail 200 connected to the track plate 100 to be replaced from the track plate 100 connected thereto;

[0070] S020, setting a lifting tool between the rail 200 whose fasteners are loosened and the corresponding track plate 100 to lift the rail 200;

[0071] Among them, a plurality of track plates 100 are arranged along the extension direction of the rail 200 , and the rail 200 and the corresponding track plates 100 are connected through the rail 200 fasteners.

[0072] Before lifting the rail 200, the rail 200 fasteners on the rail 200 are loosened with a screw machine so that each rail 200 is no longer connected to the damaged track plate 100. It should be noted that since a section of rail 200 is fixedly connected to multiple track plates 100, it is necessary to disassemble all the rail 200 fasteners on the rail 200 to be changed from the track plate 100 connected thereto. In this way, deformation and damage of the rail 200 caused by the connection between the rail 200 and the track plate 100 can be avoided when the track is lifted.

[0073] After all the rail fasteners 200 on the rail 200 are loosened, a lifting tool is installed between the first and second rail support platforms 120 at both ends of each track plate 100 and in the middle of the track plate 100, so as to lift the rail 200 by the lifting tool. Specifically, in this embodiment, the lifting tool is a jack. It should be noted that before lifting the rail 200, it is necessary to check whether all the rail fasteners 200 along the length direction of the rail 200 are all loosened.

[0074] In one embodiment, a lifting tool is provided between the rail 200 whose fasteners are loosened and the corresponding track plate 100 to lift the rail 200, including:

[0075] S021. As shown in FIG. 1 , lift the rail 200 to be at least 200 mm higher than the track plate 100.

[0076] Lift the rail 200 to at least 200 mm above the track plate 100. Specifically, lift the rail 200 to at least 200 mm above the top surface of the track plate 100. When the track plate 100 to be replaced is located in the roadbed section, the rail 200 should be lifted to at least 250 mm from the top surface of the track plate 100 so that when the track plate 100 is translated, the rail 200 will not interfere with the track plate 100, thereby facilitating the smooth movement of the track plate 100 and preventing the rail 200 from being deformed by being hit by the track plate 100.

[0077] In one embodiment, lifting the track plate 100 to be replaced to a position before it is separated from the base plate 300 includes:

[0078] S110, setting a pressing piece 1000 on the track plate 100 adjacent to the lifting plate to be lifted.

[0079] By setting a pressing piece 1000 on the track plate 100 adjacent to the track plate 100 that needs to be lifted, the track plate 100 adjacent to the track plate 100 that needs to be lifted is limited, thereby preventing the track plate 100 adjacent to the track plate 100 that needs to be lifted from being separated from the base plate 300 when the track plate 100 is lifted. Specifically, a pressing bar is set on the rail support 120 at the ends of the two track plates 100 adjacent to the track plate 100 that needs to be lifted, so as to press the track plates 100 downward, so as to prevent the two adjacent track plates 100 from being lifted when the middle track plate 100 is lifted, thereby separating the track plate 100 that does not need to be lifted from the base plate 300.

[0080] In one embodiment, as shown in FIG. 3 , lifting the track plate 100 to be replaced to be separated from the base plate 300 includes:

[0081] S210, preliminarily lifting the track plate 100 to a distance of at least 100 mm from the base plate 300;

[0082] S220, setting a lifting tool between the track plate 100 and the base plate 300;

[0083] S230, lift the track plate 100 to a distance of at least 150 mm from the base plate 300.

[0084] When the track plate 100 is initially lifted, the track plate 100 is lifted by the fine adjustment claws 900. Specifically, during the initial lifting, the track plate 100 is lifted by the fine adjustment claws 900 to a distance of at least 100 mm from the base plate 300. At this time, the track plate 100 is initially separated from the base plate 300, and there is a certain gap between the track plate 100 and the base plate 300, so as to facilitate the placement of the lifting tool between the track plate 100 and the base plate 300. After the track plate 100 is initially lifted to a certain gap between the track plate 100 and the base plate 300, a lifting tool is set between the track plate 100 and the base plate 300. Specifically, the lifting tool can be a jack. Then, the track plate 100 is continuously lifted by the jack to be lifted to a distance of at least 150 mm from the top surface of the base plate 300. When the track plate 100 to be replaced is located in the roadbed section, the track plate 100 should be lifted to a distance of at least 200 mm from the top surface of the base plate 300. In this way, the gap between the track plate 100 and the base plate 300 is large enough to facilitate the placement of the support member 400. In addition, this arrangement also facilitates the position-limiting protrusion 110 on the track plate 100 to be completely separated from the position-limiting groove 310 on the base plate 300, and the lowest point of the position-limiting protrusion 110 can be above the top surface of the base plate 300.

[0085] In one embodiment, as shown in FIG. 4 , the track plate 100 to be replaced is translated into an open space between two adjacent tracks, and before being transported out of the open space, the process includes:

[0086] S310, arranging a plurality of spaced apart support members 400 on the base plate 300;

[0087] S320, laying a support plate 500 on the support member 400;

[0088] S330 , placing the roller 600 on the support plate 500 .

[0089] A plurality of spaced support members 400 are provided on the base plate 300 to support the support plate 500. The support plate 500 is laid on the support member 400 so as to support the roller 600 through the support plate 500, and the roller 600 is provided on the support plate 500, and the track plate 100 is placed above the roller 600, so that the track plate 100 is pulled and the roller 600 rolls, so that the track plate 100 moves away from the base plate 300.

[0090] Specifically, the support member 400 is a square timber, and the support plate 500 is a steel plate. More specifically, three square timbers arranged side by side are respectively arranged on the sides of the two limiting grooves 310 on the base plate 300, and the side length of the cross section of the square timber is 100 mm. When the track plate 100 to be replaced is located in the roadbed section, the side length of the square timber is approximately 140 mm. There is no limitation on the specific structure of the support plate 500. In the present embodiment, the support plate 500 is a steel plate, and the width of the steel plate is 300 mm and the thickness is 10 mm. It can be understood that in the present embodiment, a steel plate with a width of approximately 300 mm is laid on the three square timbers located on the sides of the same limiting groove 310. Two spaced rollers 600 are placed on each steel plate. The specific roller 600 is a pulley.

[0091] As shown in FIG. 4 , in one embodiment, the track plate 100 to be replaced is translated into an open space between two adjacent tracks, and before being transported out of the open space, the process further includes:

[0092] S340, laying the support base 700 on the open ground, with the top surface of the support base 700 flush with the top surface of the base plate 300;

[0093] S350 , translate the track plate 100 to be replaced onto the support seat 700 .

[0094] By setting a support seat 700 on the open space between the two tracks, and setting the top surface of the support seat 700 to be flush with the top surface of the base plate 300, the track plate 100 to be replaced can be translated onto the support seat 700, so that the track plate 100 to be replaced can be supported by the support seat 700. Specifically, the support seat 700 is a rectangular wooden board arranged on a plurality of spaced square woods, and the top surface of the rectangular wooden board is flush with the top surface of the base plate 300. When the track plate 100 is translated to the top of the wooden board, the track plate 100 is supported by the support seat 700, so that it is convenient for the transfer tool to be supported on the bottom surface of the track plate 100 before the track plate 100 is transported out of the open space.

[0095] In this embodiment, the tool used to transport the track plate 100 out of the open space is a forklift. Specifically, the track plate 100 is forked by a forklift at each end of the track plate 100 and transported out of the open space.

[0096] In one embodiment, translating the track plate 100 to be replaced onto the support seat 700 includes:

[0097] S351, connecting one end of the adjusting member 800 to the track plate 100 to be replaced, and the other end to the base plate 300 on another track;

[0098] S352 , adjusting the adjusting member 800 to translate the track plate 100 onto the supporting seat 700 .

[0099] By connecting one end of the adjusting member 800 to the track plate 100 to be replaced and the other end to the base plate 300 on another track, the adjusting member 800 is adjusted to shorten the length of the adjusting member 800, thereby allowing the track plate 100 to be translated onto the support seat 700.

[0100] Specifically, the adjustment member 800 is a hand chain hoist. Two 10-ton hand chain hoists are arranged at intervals in the length direction of the track plate 100. One end of the hand chain hoist is fixed to the lifting hole on the track plate 100, and the other end is fixed to the reserved anchor of the base plate 300 of the other track. By adjusting the hand chain hoist, the track plate 100 can be slowly slid out of the support plate 500. After the waste track plate 100 is removed, a forklift is used to lift the track plate 100 in front and behind the track plate 100, and the track plate 100 is removed from the open space between the two tracks by the forklift, and finally transported to the vicinity of the crane and moved away from the site.

[0101] In one embodiment, before transporting the new track plate 100 to the area to be replaced and placing the track plate on the base plate, the method further includes:

[0102] S360, cleaning the surface of the base plate 300;

[0103] S370, laying geotextile on the base plate 300;

[0104] S380, install the pad and lay the steel bars.

[0105] The surface of the base plate 300 is cleaned and a geotextile is laid on the base plate 300 to improve the bonding strength between the track plate 100 and the base plate 300 after pouring. Specifically, the pad is an elastic pad. The elastic pad is arranged on the geotextile and steel bars are laid on the elastic pad to absorb the vibration of the track plate 100 through the elastic pad, thereby preventing the track plate 100 from having a hard contact with the base plate 300, thereby preventing cracking caused by the hard contact between the track plate 100 and the base plate 300 during the operation of the train. By arranging steel bars on the elastic pad, the bonding strength between the track plate 100 and the base plate 300 can be improved.

[0106] In one embodiment, before installing the steel rail 200 onto the new track plate 100, the process further includes:

[0107] S410, cleaning the new track plate 100;

[0108] S420, adjusting the position of the track plate 100;

[0109] S430, edge sealing and pouring are performed on the track plate 100.

[0110] As shown in Figures 6 to 8, the new track plate 100 is hoisted onto the bridge or the roadbed near the plate to be replaced by a crane. Two forklifts are driven in front and behind the track plate 100. The track plate 100 is lifted by the forklift and slowly moved forward to the plate replacement position. Then a square wood platform is laid between the two tracks, and the track plate 100 is smoothly dropped onto the square wood platform, and two pulleys are placed on the platform in advance. A 300mm wide and 10mm thick steel plate is laid on the base steel mesh, and two pulleys are placed on the steel plate. A 10-ton hand winch is used to slowly pull the track plate 100 onto the base plate 300, and the steel plate and pulley are removed. Before the track plate 100 is officially hoisted, a cushion should be laid on the rail 200 in advance to avoid hard contact between the lifting lug or the track plate 100 and the track plate 100 during the hoisting process, which may cause hard damage to the rail 200.

[0111] The self-compacting concrete is transported by a tank truck to the entrance of the accessory logistics channel of the track plate 100 that needs to be replaced. In the case of a large train, the self-compacting concrete is hoisted to the vicinity of the large train by a crane, and hoisted to the position where the track plate 100 needs to be replaced, and then self-compacting pouring is carried out. In the absence of a large train, a forklift can be used to transport the self-compacting concrete for pouring. During the maintenance of the track plate 100, warning signs, full-time safety officers and guards are set up to ensure that the strength of the self-compacting concrete meets the design requirements. After the strength of the self-compacting concrete meets the design requirements, lock the fasteners of the track plate 100 with a torque of not less than 160 N.m. Finally, check the track status and replace the fasteners if they exceed the limit. It should be noted that before pouring the self-compacting concrete, it is necessary to press the pressure bar on the track plate 100 to fix the track plate 100.

[0112] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
