Technical Field

[0001] This invention relates to the field of railway track emergency repair technology, specifically a rapid assembly support structure for railway track emergency repair. Background Technology

[0002] Railway track emergency repair is a highly organized and professional task aimed at restoring the line's operational capacity in the shortest possible time and ensuring train safety.

[0003] During emergency repairs of railway tracks, support structures are needed to support the rails. Existing support structures are mostly monolithic, resulting in large overall mass and volume. When transporting and moving them, multiple people are required to work together, which can easily lead to slow transfer speeds, hindering emergency repairs of railway tracks. To address these technical problems, we have designed a rapid-assembly support structure for emergency railway track repairs. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid assembly support structure for emergency repair of railway tracks, comprising two restraint covers, each restraint cover having a slot 1 through-cut on one side facing each other, and a slot 2 through-cut on one side away from each other. A mounting plate is connected to the rear side of the restraint covers, and several mounting holes are through-cut on the top of the mounting plate. A bearing component is installed between the two slots 1, and a lifting component is installed between the two slots 2. A support component is installed on the lifting component. The bearing component includes an L-shaped bearing plate, with a notch through-cut on the front side of the L-shaped bearing plate. L-shaped clamping plates are connected to both sides of the L-shaped bearing plate. Mounting screw holes are opened on both sides of the top of the L-shaped bearing plate, and guide rods are threaded onto the inner walls of the mounting screw holes.

[0007] Preferably, the outer side of the L-shaped card plate is in sliding contact with the inner wall of the card slot, and the front and rear sides of the top of the inner wall of the card slot are provided with placement notches for use with the L-shaped card plate.

[0008] Preferably, the lifting component includes a gantry frame, with locking strips connected to the bottom of both the left and right sides of the inner wall of the gantry frame for use with the second locking slot. The left and right sides of the inner wall of the gantry frame are respectively fitted onto the opposite sides of the two restraint covers. Baffles are connected to the bottom of both the left and right sides of the front surface of the gantry frame. A positioning plate is connected between the two baffles. The rear side of the positioning plate has a through notch. Damping rods are connected to the top of the opposite sides of the front surfaces of the two restraint covers. A positioning plate is rotatably fitted onto the outside of the damping rod. The rear side of the positioning plate is in sliding contact with the gantry frame.

[0009] Preferably, the top of the gantry frame has connecting screw holes on both the left and right sides, a support block is connected to the center of the top of the front surface of the gantry frame, a lifting screw is provided on the top of the support block, a polygonal column is connected to the top of the lifting screw, and the bottom of the lifting screw passes through the support block and extends into the interior of the positioning plate.

[0010] Preferably, the top of the positioning plate is provided with a support hole for use with the lifting screw, and scale plates are connected to the left and right sides of the top center of the gantry frame, with the two scale plates located on the left and right sides of the lifting screw respectively.

[0011] Preferably, the supporting component includes a lifting block, a lifting plate connected to the rear side of the lifting block, and docking grooves on the left and right sides of the front and rear sides of the lifting plate. A docking block is inserted into the docking groove on the rear side. Positioning screws are provided on the left and right sides of the rear top of the lifting plate, and the bottom of the positioning screws passes through the lifting plate and the docking block.

[0012] Preferably, a lifting beam is connected to the rear side of the docking block, a moving groove is provided on the top of the lifting beam, an adjusting screw is installed through the moving groove, guide blocks are connected to the front side of the opposite side of the two lifting beams, and positioning holes are provided through the four corners of the top of the lifting plate and the top of the docking block.

[0013] Preferably, two restraining components are installed on the outside of the adjusting screw. The restraining components include a moving block, which is threaded onto the outside of the adjusting screw. A moving plate is engaged with the top of the moving block. A moving window is opened through the top of the front side of the moving plate. A positioning clamp is slidably arranged on the inner wall of the moving window. A moving screw hole is opened at the center of the two positioning clamps on opposite sides.

[0014] Preferably, a U-shaped frame is connected to the side of each of the two movable plates that is far apart. A clamping screw is provided through the U-shaped frame, and the opposite side of the two clamping screws extends into the interior of the movable screw hole and is threadedly connected to the inner wall of the movable screw hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the combined use of a restraint cover, lifting component, support component, load-bearing component, mounting plate, damping rod, slot one, positioning plate, slot two, and mounting hole. This provides the advantage of splicing installation. An L-shaped clamping plate is inserted into slot one to complete the installation of the load-bearing component. A clamping strip is inserted into slot two to complete the installation of the lifting component. A connecting block is inserted into the connecting groove. A positioning screw passes through the lifting plate and the connecting block to position the lifting beam. A moving plate is clamped onto the top of the moving block to complete the splicing installation. This avoids the entire support structure being unable to be assembled and disassembled, resulting in a large overall weight and hindering the carrying and transfer of the support structure.

[0017] 2. By placing a notch, the protruding end of the L-shaped card plate can be accommodated. Furthermore, the combination of the notch and the L-shaped card plate can limit the L-shaped support plate, preventing it from moving freely and detaching from the restraint cover.

[0018] 3. By using two displacement plates, the L-shaped support plate can be placed on top of the rail, and the displacement plates are stuck on both sides of the rail. Subsequently, the support structure is pushed, so that the moving roller moves on top of the rail, completing the transfer of the support structure. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 Please see Figures 1-7 A rapid assembly support structure for emergency repair of railway tracks includes two restraint covers 1. Each restraint cover 1 has a slot 7 extending through its opposite side, and a slot 9 extending away from its opposite side. A mounting plate 5 is connected to the rear of each restraint cover 1. Several mounting holes 10 extend through the top of the mounting plate 5. A bearing component 4 is installed between the two slots 7, and a lifting component 2 is installed between the two slots 9. A support component 3 is installed on the lifting component 2. The bearing component 4 includes an L-shaped bearing plate 42. A notch 41 extends through the front of the L-shaped bearing plate 42. L-shaped clamping plates 43 are connected to both sides of the L-shaped bearing plate 42. Mounting screw holes 44 are opened on both the left and right sides of the top of the L-shaped bearing plate 42. Guide rods 45 are threaded onto the inner walls of the mounting screw holes 44; the guide rods 45 are double-ended screws.

[0024] The outer side of the L-shaped card plate 43 slides in contact with the inner wall of the card slot 7. The front and rear sides of the top of the inner wall of the card slot 7 are provided with placement notches 11 for use with the L-shaped card plate 43.

[0025] The L-shaped card plate 43 and the slot 7 work together to facilitate the installation of the bearing component 4 between the two restraint covers 1. The placement notch 11 can be used to store the protruding end of the L-shaped card plate 43. The placement notch 11 and the L-shaped card plate 43 work together to limit the L-shaped bearing plate 42 and prevent it from moving away from the restraint cover 1.

[0026] The lifting component 2 includes a gantry frame 26. The bottom of the left and right sides of the inner wall of the gantry frame 26 is connected to a locking strip 21 that works with the locking slot 9. The left and right sides of the inner wall of the gantry frame 26 are respectively fitted onto the opposite sides of the two restraint covers 1. The bottom of the left and right sides of the front surface of the gantry frame 26 is connected to a baffle 22. The two baffles 22 are connected together by a positioning plate 23. The rear side of the positioning plate 23 has a through notch 41. The top of the opposite sides of the front surface of the two restraint covers 1 is connected to a damping rod 6. The outside of the damping rod 6 is fitted with a positioning plate 8. The rear side of the positioning plate 8 is in sliding contact with the gantry frame 26. The rear side of the baffle 22 is in contact with the front side of the L-shaped bearing plate 42.

[0027] The cooperation of slot 29 and clip 21 facilitates the installation of lifting component 2 on the two restraint covers 1. The use of gantry 26 can limit and restrain the two restraint covers 1, keeping the distance between them constant and preventing changes. The baffle 22 can limit the L-shaped bearing plate 42, preventing it from moving forward and detaching from the two restraint covers 1 after installation. Furthermore, the cooperation of damping rod 6 and positioning plate 8 can position gantry 26, preventing clip 21 from moving forward arbitrarily on the inner wall of slot 29 and detaching it from the restraint cover 1.

[0028] The top of the gantry 26 has connecting screw holes 29 on both the left and right sides. A support block 28 is connected to the center of the top of the front surface of the gantry 26. A lifting screw 24 is provided on the top of the support block 28. A polygonal column 27 is connected to the top of the lifting screw 24. The bottom of the lifting screw 24 passes through the support block 28 and extends into the interior of the positioning plate 23. The connecting screw holes 29 are used in conjunction with the guide rod 45.

[0029] Windows are provided on both the left and right sides of the inner wall of the gantry frame 26. The opening of these windows reduces its overall weight and facilitates its handling and installation.

[0030] The top of the positioning plate 23 has a support hole for use with the lifting screw 24. The left and right sides of the top center of the front surface of the gantry 26 are connected to scale plates 25, and the two scale plates 25 are located on the left and right sides of the lifting screw 24 respectively.

[0031] The threads on the outside of the lifting screw 24 are located between the bottom of the support block 28 and the top of the positioning plate 23, and the bottom of the outside of the lifting screw 24 is movably connected to the inner wall of the support hole through a bearing; the use of the scale plate 25 allows for precise knowledge of the lifting height of the lifting block 32, which is beneficial for knowing the lifting amount of the rail in the future.

[0032] The support component 3 includes a lifting block 32, a lifting plate 34 connected to the rear side of the lifting block 32, and docking grooves 31 on the left and right sides of the front and rear sides of the lifting plate 34. A docking block 35 is inserted into the rear docking groove 31. Positioning screws 36 are provided on the left and right sides of the rear top of the lifting plate 34. The bottom of the positioning screws 36 passes through the lifting plate 34 and the docking block 35. The inner wall of the lifting block 32 is threaded onto the outside of the lifting screw 24.

[0033] Two scale plates 25 are also located on the left and right sides of the lifting block 32 respectively. The two scale plates 25 can also limit the lifting block 32 to prevent the lifting block 32 from rotating when the lifting screw 24 rotates.

[0034] A lifting beam 37 is connected to the rear side of the docking block 35. A moving groove 310 is provided on the top of the lifting beam 37. An adjusting screw 38 is installed through the inside of the moving groove 310. Guide blocks 311 are connected to the front side of the opposite side of the two lifting beams 37. Positioning holes 33 are provided through the four corners of the top of the lifting plate 34 and the top of the docking block 35. A guide hole is provided through the top of the guide block 311. The inner wall of the guide hole is slidably sleeved on the outside of the guide rod 45. The rear side of the adjusting screw 38 extends to the rear side of the lifting beam 37.

[0035] By utilizing the cooperation of guide block 311 and guide rod 45, the lifting beam 37 can be guided to rise and fall, thereby improving its stability. Furthermore, the positioning hole 33 at the top of the lifting plate 34 is a stepped hole, and the through hole at the bottom of the lifting plate 34 is a threaded hole. The inner wall of the threaded hole is connected to the external thread of the positioning screw 36. The bottom of the stepped hole and the top of the threaded hole are both connected to the docking groove 31. Furthermore, the hole on the docking block 35 is a normal hole, which facilitates the positioning screw 36 to pass through the docking block 35.

[0036] Example 2 Please see Figure 8 and Figure 9 Two restraining components 39 are installed on the outside of the adjusting screw 38. Each restraining component 39 includes a moving block 397, which is threaded onto the outside of the adjusting screw 38. A moving plate 391 is snapped onto the top of the moving block 397. A moving window 394 is provided through the top of the front side of the moving plate 391. A positioning clamp 396 is slidably provided on the inner wall of the moving window 394. A moving screw hole 395 is provided at the center of the two positioning clamps 396 on the side away from each other.

[0037] The movable window 394 facilitates the forward and backward movement of the positioning clamp 396; the two positioning clamps 396 can be used to clamp the rail, improving the stability of the rail support; it should be noted that when the two moving blocks 397 move outside the adjusting screw 38, their movement directions are the same.

[0038] Each of the two movable plates 391 is connected to a U-shaped frame 392 on the side away from each other. A clamping screw 393 is provided through the U-shaped frame 392. The opposite side of the two clamping screws 393 extends into the interior of the movable screw hole 395 and is threadedly connected to the inner wall of the movable screw hole 395.

[0039] The U-shaped bracket 392 can be used to support the clamping screw 393, which is beneficial to the rotation of the clamping screw 393.

[0040] The left and right sides of the bottom of the L-shaped support plate 42 are connected to displacement plates 47, and several movable rollers 46 are installed between the two displacement plates 47.

[0041] By using two displacement plates 47, the L-shaped support plate 42 can be placed on top of the rail, and the displacement plates 47 are locked on both sides of the rail. Subsequently, the support structure is pushed, so that the moving roller 46 moves on top of the rail, completing the transfer of the support structure.

[0042] In use, the rail is supported on the outside of the railway, the rail clamp for positioning the rail is removed, and two restraint covers 1 are fitted on the outside of two adjacent sleepers (in order to place the restraint covers 1 stably, the ballast bed on both sides of the sleepers needs to be cleaned). When the restraint covers 1 are fitted on the outside of the sleepers, the mounting holes 10 on the mounting plate 5 are fitted on the screws fitted by the rail clamp, and the mounting plate 5 is positioned by using nuts, which also positions the restraint covers 1.

[0043] The two L-shaped clamping plates 43 on the bearing component 4 are inserted into the first clamping slot 7, completing the installation of the bearing component 4. Next, the two clamping strips 21 on the lifting component 2 are inserted into the second clamping slot 9, and the positioning clamping plate 23 passes through the notch 41, completing the installation of the lifting component 2. The positioning plate 8 is rotated from a vertical state to a horizontal state and is located in front of the gantry 26, completing the positioning of the gantry 26. At this time, the rear side of the baffle 22 contacts the L-shaped bearing plate 42, completing the positioning of the bearing component 4. The docking block 35 on the support component 3 is inserted into the docking groove 31 on the rear side. The positioning screw 36 passes through the lifting plate 34 and the docking block 35 to complete the positioning of the lifting beam 37. It should be noted that when installing the lifting beam 37, it needs to pass under the rail. After the lifting beam 37 is installed, the moving plate 391 is snapped into the top of the moving block 397. Furthermore, the two moving plates 391 are located on the front and rear sides of the rail, respectively. The guide rod 45 passes through the guide block 311 and is threadedly connected to the mounting screw hole 44.

[0044] Rotating the two clamping screws 393 clockwise and backward respectively causes the two positioning blocks 396 to move towards the "I"-shaped notch of the rail, thus clamping and positioning the rail. Subsequently, a socket wrench is placed outside the polygonal column 27 and rotated clockwise, causing the lifting block 32 to rise outside the lifting screw 24. This, in turn, causes the lifting plate 34 and the lifting beam 37 to rise, supporting the rail with the lifting beam 37. It should be noted that the two lifting beams 37 can support the same rail or simultaneously lift two adjacent rails (in which case one lifting beam 37 supports one rail, and when supporting two rails, the two lifting beams 37 are located on both sides of the interface of the two rails respectively); when supporting two rails simultaneously, if there is misalignment at the interface of the two rails, one of the adjusting screws 38 can be rotated clockwise or counterclockwise to make the two moving blocks 397 move in the same direction, thereby using the two binding components 39 to push the rails so that the interface is aligned; furthermore, when the two lifting beams 37 support the same rail, the binding component 39 on one of the lifting beams 37 can be used to correct a single rail (when the rail is slightly deformed).

[0045] Alternatively, a single support structure can be used to simultaneously support two parallel rails. In this case, two restraint covers 1 should be fitted onto the outside of two adjacent sleepers, positioned between the two rails. The mounting plate 5 should be offset towards one of the rails to facilitate subsequent positioning and installation. Then, connecting blocks 35 are inserted into the connecting grooves 31 on both the front and rear sides of the lifting plate 34 to complete the installation of the four lifting beams 37. After that, normal support operations can be carried out. It should be noted that the ballast bed on both sides of the sleepers also needs to be cleaned.

[0046] After the current support work is completed, if it is necessary to move the support structure to another location for support work, firstly, the mounting plate 5 is removed from the screws fitted with the rail clamp; then, the L-shaped bearing plate 42 is placed on top of the rail, and the displacement plate 47 is secured on both sides of the rail. Pushing the support structure causes the moving roller 46 to move on top of the rail, completing the transfer of the support structure. After being transferred to the required location, the support structure is reinstalled. This transfer method eliminates the need for workers to move the structure over long distances, reducing physical exertion. It should be noted that when workers are carrying the support structure to the rail support location (this method describes the situation before the first support, i.e., when workers carry the support structure along the railway line but are still a considerable distance from the support location), they first assemble and install the two restraint covers 1, the lifting component 2, and the bearing component 4. Then, the L-shaped bearing plate 42 is placed on top of the rail, and the support structure is pushed in the above manner. This improves the efficiency of the support structure transfer and is beneficial for emergency repairs.

[0047] After the support structure is used, each component is disassembled one by one. The disassembled lifting beam 37 is placed horizontally on the top of the lifting plate 34, and its positioning is completed by using the positioning hole 33 and the positioning screw 36. The guide rod 45 is rotated off and threaded into the connecting screw hole 29 to complete the connection with the gantry 26.

[0048] It should be noted that any content not described in detail in this specification belongs to the prior art known to those skilled in the art. The specific embodiments described herein are merely illustrative examples of the spirit of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
