Description

Technical Field

[0001] This invention relates to the field of track technology, specifically to a track structure and track, and more particularly to a damaged track replacement device. Background Technology

[0002] Rail transit refers to a type of transportation or system where vehicles need to run on specific tracks. The most typical rail transit system is the railway system, which consists of traditional trains and standard railways. With the diversified development of train and railway technologies, rail transit has taken on more and more types, not only covering long-distance land transportation but also being widely used in short- and medium-distance urban public transportation.

[0003] In rail transit, tracks need to be laid to facilitate vehicle movement. When the train moves, the train wheels wear down the tracks, especially at points where the tracks are about to bend. Due to the pull of the locomotive on the carriages, the carriage wheels experience intense friction with the tracks, resulting in severe damage. Currently, the repair of severely damaged tracks mostly involves replacing them directly. However, this method of track maintenance is costly and difficult. Furthermore, once the tracks are replaced, they are difficult to recycle, failing to achieve the goal of saving resources.

[0004] Patent document CN 211312021 U discloses a railway track that is easy to replace, including a sleeper body, a track body on top of the sleeper body, pressure plates on the left and right sides of the top of the sleeper body, the bottom of the pressure plates contacting the surface of the track body, connecting blocks fixedly connected to the front and rear sides of the top of the sleeper body, a rocker arm movably connected to the surface of the connecting block via a pin, a connecting plate fixedly connected to the end of the rocker arm away from the connecting block, and a bolt on the left side of the connecting plate.

[0046] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0047] This invention provides a track structure, such as Figure 1-10 As shown, it includes a track connecting device 1, a slab support track 2, a protective replacement device 3, and sleepers 5; the two slab support tracks 2 are connected by the track connecting device 1, and the sleepers 5 are arranged on both sides of the track connecting device 1 to support the slab support track 2; the protective replacement device 3 is detachably installed on the top of the slab support track 2 to support external trains.

[0048] The track connecting device 1 includes a connecting support frame 11 and a pressing plate 13 disposed on the connecting support frame 11. Preferably, the pressing plate 13 is installed at the four corners of the connecting support frame 11. The connecting support frame 11 includes a bottom support plate 111, connecting blocks 116, side inserts 118, and a track sub-plate 112 fixed at the upper middle position of the bottom support plate 111.

There are multiple connecting blocks 116, which are fixed on the bottom support plate 111 and evenly arranged along the circumference of the track sub-plate 112. Preferably, the pressing plate 13 is screwed to the connecting blocks 116, and four connecting blocks 116 are respectively installed at the four corners of the track sub-plate 112. The bottom of the pressing plate 13 is engaged with the plate support track 2.

[0049] like Figure 6 As shown, the plate support track 2 includes an I-shaped connecting support bar 21. The track sub-plate 112 and the connecting support bar 21 have the same shape. The top of the connecting support bar 21 is symmetrically provided with track grooves 24. Multiple upper insertion holes 23 are provided between the two track grooves 24 along the length of the connecting support bar 21. Mounting holes 26 are also provided on both sides of the connecting support bar 21. The two sides of the track sub-plate 112 are in contact with the two connecting support bars 21 respectively, and the side insertion post 118 is inserted into the mounting hole 26. The bottom of the pressing plate 13 is engaged with the edge of the connecting support bar 21.

[0050] like Figure 7-8 As shown, the protective replacement device 3 includes an upper protective frame 31, which includes a U-shaped frame 311, a limiting strip 314, and a limiting post 313. The U-shaped frame 311 is symmetrically and fixedly connected with the limiting strip 314 on the left and right sides. The length direction of the limiting strip 314 is consistent with the length direction of the U-shaped frame 311. Between two limiting strips 314, along the length direction of the U-shaped frame 311, a plurality of limiting posts 313 are fixedly connected. The U-shaped frame 311 is sleeved on the upper end of the connecting support bar 21.

[0052] like Figure 1 , Figure 2 , Figure 10 As shown, to improve the connection between the two plate support rails 2, a fixing connection device 4 is provided between the two plate support rails 2. The fixing connection device 4 includes two connecting strips 41 disposed on both sides of the connecting support strip 21. The two ends of the two connecting strips 41 are connected to each other. Specifically, the two ends of the two connecting strips 41 are connected together by nuts. A limiting protrusion strip 42 is fixed to the bottom of the connecting strip 41. The limiting protrusion strip 42 is inserted into the connecting support strip 21. Specifically, as shown... Figure 6 As shown, a second mounting groove 28 is provided on the connecting support bar 21, extending along the length of the connecting support bar 21. The limiting protrusion 42 is inserted into the second mounting groove 28. This invention connects two plate support rails 2 together using screws, ensuring that the connecting support bar 21 and the rail sub-plate 112 fit together. This guarantees the stability of the connection between the plate support rail 2 and the rail connecting device 1, strengthens the integrity between the rail connecting device 1 and the plate support rail 2, and facilitates the restriction and support of the protective replacement device 3 by the rail connecting device 1 and the plate support rail 2.

[0053] Both sides of the bottom of the track subplate 112 are fixedly connected to side insert plates 117. A side slot 25 is provided on the side wall at the bottom end of the connecting support bar 21, and the side insert plate 117 is slidably inserted into the side slot 25. This design improves the lateral support strength between the track connecting device 1 and the plate support rail 2, preventing the track connecting device 1 and the plate support rail 2 from separating when the train turns, thus enhancing the stability of the connection between the track connecting device 1 and the plate support rail 2.

[0054] like Figure 4As shown, the connecting support frame 11 has a rod insertion cavity 114 and a spiral connection cavity 115 inside. Specifically, the rod insertion cavity 114 and the spiral connection cavity 115 are both located inside the bottom support plate 111. The rod insertion cavity 114 and the spiral connection cavity 115 are interconnected. The spiral connection cavity 115 has a threaded structure, and its end penetrates the bottom support plate 111. The bottom support plate 111 also has a connection placement groove 113. The two rod insertion cavities 114 are connected through the connection placement groove 113, meaning that the ends of both rod insertion cavities 114 are connected to the connection placement groove 113. The bottom support plate 111 also has multiple auxiliary positioning devices 12 inside. In a preferred embodiment, the connecting support frame 11 has rod insertion cavities 114 and spiral connection cavities 115 at its four corners, and multiple auxiliary positioning devices 12 are symmetrically arranged at the four corners of the bottom support plate 111.

[0055] like Figure 5 As shown, the auxiliary positioning device 12 includes an auxiliary rod 121, a spring 122, and a threaded post 123; the spring 122 is sleeved on the auxiliary rod 121, and the end of the auxiliary rod 121 is fastened to the threaded post 123.

[0056] A portion of the auxiliary insert rod 121 and the spring 122 are disposed inside the insert rod sliding cavity 114. One end of the threaded post 123 is disposed in the helical connection cavity 115, and the threaded post 123 matches the threaded structure. One end of the auxiliary insert rod 121 passes through the insert rod sliding cavity 114 and is inserted into the helical connection cavity 115, contacting the other end of the threaded post 123. A low insertion strip 22 is fixedly connected to the bottom of the connecting support strip 21, and the low insertion strip 22 is disposed inside the connecting placement groove 113. The other end of the auxiliary insert rod 121 passes through the insert rod sliding cavity 114 and is inserted into the low insertion strip. Inside 22; by rotating the threaded post 123, the threaded post 123 and the threaded groove are connected, causing the threaded post 123 to push one end of the auxiliary insert rod 121 into the low insert strip 22, fixing the low insert strip 22 in the connecting placement groove 113. Simultaneously, the connection effect of the side insert post 118 being inserted into the connecting support strip 21 and the side insert plate 117 being inserted into the side slot 25 is strengthened, thereby improving the connection effect between the track connecting device 1 and the plate support track 2, ensuring stable support of the protective replacement device 3 by the track connecting device 1 and the plate support track 2. This invention uses an auxiliary positioning device to insert one end of the connecting support strip, connecting the connecting support strip and the track connecting device into a whole, facilitating stable fixation between the track connecting device and the plate support track, thus achieving the technical effect of stable support of the protective replacement device by the track connecting device and the plate support track.

[0057] In a preferred embodiment, an upwardly inclined chute is provided on the connection placement groove 113 near the edge of the bottom support plate 111.

[0058] The present invention also provides a track employing the aforementioned track structure.

[0059] The working principle of this invention is as follows:

[0060] When the track connecting device 1, the plate support rail 2, and the protective replacement device 3 are in use, and the upper protective frame 31 is severely worn by the train, the workers remove the locking plate 32 from the U-shaped frame 311, pull the locking block 321 away from the connecting support bar 21, and after removing the locking plate 32 from the upper protective frame 31, the workers lift the damaged upper protective frame 31 away from the plate support rail 2, and place the upper protective frame 31 that needs to be replaced on the plate support rail 2. The U-shaped frame 3... 11 is set on the connecting support bar 21, the limiting plug 313 is inserted into the upper insertion hole 23, the limiting clip 314 is inserted into the inside of the track groove 24, and the clip plate 32 is inserted into the side insertion fixing hole 312. The clip plate 32 is fixed on the U-shaped frame 311 with screws, and the clip block 321 is inserted into the connecting support bar 21, so that the upper protective frame 31 is fixed on the connecting support bar 21, so as to facilitate the support of the upper protective frame 31 for the train and ensure the normal use of the replaced upper protective frame 31.
