[0030] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0031] In an embodiment of the present invention, a sleeper handling device for railway construction is disclosed, as Figures 1 - 9As shown in the figure, it includes: a frame body 1, the frame body 1 is in an inverted "U" shape, and its lower part is used to accommodate the railway track. Connecting frames 2 and auxiliary frames 4 are respectively fixedly connected to both sides of the frame body 1. One side of the auxiliary frame 4 close to the frame body 1 extends outward for a part. During use, the connecting frame 2 and the auxiliary frame 4 are respectively located on both sides of the railway track; a propulsion assembly, which is arranged on the surface of the connecting frame 2. The propulsion assembly includes a sliding plate 22 slidably connected to the surface of the connecting frame 2. One side of the inner wall of the connecting frame 2 is fixedly connected with a motor A21. The output end of the motor A21 is fixedly connected with a screw rod 211. One end of the screw rod 211 is rotatably connected to the inner wall of the connecting frame 2. The screw rod 211 is threadedly connected with the sliding plate 22. When the screw rod 211 rotates, the sliding plate 22 will slide on the surface of the connecting frame 2. Guide rails 221 are hinged on both sides of the sliding plate 22. The guide rails 221 can rotate on both sides of the sliding plate 22, and the upper part of the guide rails 221 is used to carry the sleeper. A support assembly for receiving the sleeper is installed at one end of the guide rail 221 away from the sliding plate 22; several rotating shafts 41 are rotatably connected to the inner wall of the auxiliary frame 4; a base A3 is arranged at the bottom of the connecting frame 2. The base A3 is connected to the connecting frame 2 through a cylinder A31. One end of the cylinder A31 is fixedly connected with the base A3, and the other end is fixedly connected with the connecting frame 2. A base B44 is arranged at the bottom of the auxiliary frame 4. The base B44 is connected to the auxiliary frame 4 through a cylinder B441. One end of the cylinder B441 is fixedly connected with the base B44, and the other end is fixedly connected with the auxiliary frame 4.

[0032] Specifically, by erecting the frame body 1 above the railway track, and the connecting frame 2 and the auxiliary frame 4 are respectively located on both sides of the railway track. After cleaning the buffer ballast around and below the target sleeper, the outer edge of one side of the auxiliary frame 4 close to the frame body 1 is placed under one side of the target sleeper, and the support assembly is located on the other side under the target sleeper. If there is a deviation in position, the motor A21 outputs to drive the screw rod 211 to rotate, so that the sliding plate 22 drives the support assembly at one end of the guide rail 221 to adjust the position until it moves under the target sleeper. By removing the track bolts on the surface of the old sleeper under the railway track, the connection between the old sleeper and the railway track is cancelled. The old sleeper will be caught by the support assembly and the auxiliary frame 4. Subsequently, through the output of the motor A21, the old sleeper is pushed out towards the side of the auxiliary frame 4, as Figure 7 shown in the figure, the arrow indicates the traveling direction. By the way of external pushing, there is no need to lift the old sleeper upwards, thus avoiding being blocked by the railway track.

[0033] In addition, a new sleeper can be placed on the surface of the guide rail 221. When the guide rail 221 moves and pushes out the old sleeper, the new sleeper enters under the railway track synchronously with the guide rail 221. At this time, it can be directly fixed to the railway track through track bolts. The two are carried out synchronously, which improves the handling and replacement efficiency of the sleeper to a certain extent and effectively avoids the problem that it is inconvenient to place the sleeper under the railway track due to the obstruction of the track.

[0034] Subsequently, since the guide rail 221 is hinged to the sliding plate 22, after the new sleeper on the surface of the guide rail 221 is connected under the railway track, by reversing the motor A21, the screw 211 is reversed to drive the sliding plate 22 to return to the normal position. During this process, the support assembly is blocked by the new sleeper, causing the two guide rails 221 to rotate and expand in the direction away from each other, as Figure 4 shown in the state, which facilitates the return of the sliding plate 22 to the normal position and also allows the guide rail 221 to be withdrawn from under the railway track, facilitating the handling and replacement of the next sleeper.

[0035] It should be noted that, under normal conditions, the two guide rails 221 are parallel to each other.

[0036] The support assembly includes a baffle 222 fixedly connected to one end of the guide rail 221 away from the sliding plate 22. A receiving plate 223 is fixedly connected to the surface of the baffle 222. The receiving plate 223 is placed perpendicular to the baffle 222. Specifically, the receiving plate 223 contacts the bottom of the sleeper to support the sleeper, and the baffle 222 is used to position the sleeper when pushing the sleeper.

[0037] Furthermore, in this embodiment, a positioning ring 225 is fixedly connected to the top of the baffle 222.

[0038] Specifically, another method for handling and replacing the sleeper is provided. As Figure 8 shown, the arrow indicates the traveling direction. Here, the function of the positioning ring 225 is to reverse the process of handling and replacing the sleeper. Different from the above construction process, here the new sleeper is placed on the surface of the auxiliary frame 4, and no sleeper is placed on the surface of the guide rail 221. By the output of the motor A21, the sliding plate 22 is driven to move towards the direction of the old sleeper, so that the baffle 222 can drive the guide rail 221 to rotate and expand when blocked by the old sleeper, so that the guide rail 221 moves under the old sleeper. At this time, one end of a steel wire rope or steel chain is connected to the positioning ring 225 on the surface of the baffle 222, and the other end is connected to the sleeper bolt on the surface of the new sleeper, so that one end of the new sleeper is placed on the surface of the receiving plate 223. After removing the track bolt of the old sleeper, by reversing the motor A21, the old sleeper is moved outwards, and at the same time the new sleeper is driven by the steel wire rope or steel chain to be pulled into the railway track and installed. This is applicable to the situation where the new sleepers are placed on both sides of the track, and the replacement can be carried out from any side of the track. It is also applicable to the temporary track diversion area. If the original side where the new sleeper is placed is blocked by other tracks and is replaced by the other side, in this way, there is no need to adjust the positions of the connecting frame 2 and the auxiliary frame 4, and the handling and replacement of the sleeper can also be carried out, providing a more flexible operation method and a wider applicability for this device.

[0039] As Figure 3 and Figure 4As shown, in this embodiment, rollers 226 are rotatably connected to the opposite sides of the two baffles 222. The rollers 226 are used to contact and roll on the sleepers to reduce friction and prevent the baffles 222 from directly contacting the sleepers during the unfolding process of the two guide rails 221. Two stoppers 23 are fixedly connected to the bottom surface of the frame 1 near the two guide rails 221. The two stoppers 23 are arranged between the two guide rails 221 and are used to limit the distance between the two guide rails 221. An impeller 251 is axially fixedly connected to the lower end of the roller 226. The impeller 251 is used to stir the buffer ballast under the railway track. The impeller 251 is made of aluminum alloy or stainless steel and has high wear resistance. An arc-shaped block 25 adapted to the impeller 251 is fixedly connected to the bottom of the baffle 222. The arc-shaped block 25 is used to protect one side of the impeller 251. An outward expansion plate 252 is fixedly connected to the surface of the arc-shaped block 25.

[0040] Specifically, when the guide rail 221 unfolds and the roller 226 contacts the surface of the sleeper, the forward movement of the sliding plate 22 will cause the roller 226 to roll. When the sliding plate 22 moves toward the side of the auxiliary frame 4, that is, when the guide rail 221 needs to be inserted under the old sleeper, the arc-shaped block 25 is used to protect the impeller 251, and the impeller 251 can be driven to rotate by the rotation of the roller 226, thereby sweeping the stones on both sides of the sleeper outward, so as to facilitate the insertion of the guide rail 221 under the sleeper. Correspondingly, when the sliding plate 22 moves toward the side away from the auxiliary frame 4, that is, when the guide rail 221 is removed after the new sleeper is installed, the roller 226 rolls in the reverse direction, and under the action of the outward expansion plate 252, the stones on both sides of the sleeper are guided into the outward expansion plate 252 and the arc-shaped block 25, so as to facilitate the rotation of the impeller 251 and fill the stones under the sleeper to ensure the stability of the bottom of the sleeper after installation. Through the setting of the impeller 251, during the process of transporting and replacing the sleeper, the stones can be flexibly swept out or filled in, reducing the labor intensity of manual operation and improving the installation stability of the sleeper.

[0041] Furthermore, two sliders 231 are slidably connected to the bottom surface of the frame 1. The sliders 231 are connected to the frame 1 through springs 232. Both ends of the springs 232 are fixedly connected to the sliders 231 and the frame 1 respectively, and the guide rail 221 is located between the stopper 23 and the slider 231. In this way, during the unfolding process of the guide rail 221, the slider 231 will be pushed outward, causing the slider 231 to slide on the bottom surface of the frame 1 and simultaneously compressing the spring 232. The rebound of the spring 232 can facilitate the pushing of the slider 231, so that the guide rail 221 returns to the initial position.

[0042] A limit block A224 is fixedly connected to the surface of the receiving plate 223. There are limit blocks A224 on the surfaces of the two receiving plates 223. Two limit blocks B42 are fixedly connected to the surface of the auxiliary frame 4 opposite to the receiving plate 223. The limit blocks A224 and the limit blocks B42 are both used to limit the sleeper.

[0043] Furthermore, an electric push rod 24 is fixedly connected to one side of the connecting frame 2 close to the frame body 1, and a U-shaped plate 241 adapted to the two guide rails 221 is fixedly connected to the output end of the electric push rod 24. When the two guide rails 221 are in a fit state with the stop block 23, the electric push rod 24 is output to push the U-shaped plate 241 upward, and both arms of the U-shaped plate 241 are stuck on the side where the two guide rails 221 are away from each other, thereby positioning the guide rail 221. At this time, the guide rail 221 cannot rotate on the surface of the sliding plate 22, which is suitable for the process in which the guide rail 221 pushes or carries the sleeper to move. When the guide rail 221 needs to be rotated and unfolded, the electric push rod 24 is contracted to move the U-shaped plate 241 downward, thereby canceling the positioning of the guide rail 221.

[0044] Both sides of the base A3 are rotatably connected to a plurality of rollers 32, and the bottom of the base B44 is rotatably connected to a plurality of universal wheels 442. By arranging the rollers 32 and the universal wheels 442, the entire device can be conveniently moved.

[0045] Furthermore, it also includes a driving component, which includes a motor B33 fixedly connected to the surface of the base A3, a driving shaft 321 rotatably connected inside the base A3, two ends of the driving shaft 321 are respectively fixedly connected to two opposite rollers 32, a driving disk 322 is fixedly connected to the surface of the driving shaft 321, and the output end of the motor B33 is connected to the driving disk 322 through a belt. The output end of the motor B33 can be connected to an active disk with a diameter smaller than the driving disk 322, and then connected to the driving disk 322 through a transmission belt of the active disk, and then through the output of the motor B33, the transmission belt drives the driving disk 322 to rotate, and then the driving shaft 321 drives the roller 32 to rotate, thereby driving the entire device to move. After the sleeper is transported and replaced, the entire device is moved to the next sleeper position that needs to be replaced by driving the motor B33.

[0046] A side of the auxiliary frame 4 away from the frame body 1 is fixedly connected with an inclined plate 43, through which the upper and lower sleepers are conveniently placed.

[0047] Working principle: By installing the frame 1 above the railway track, the connecting frame 2 and the auxiliary frame 4 are arranged on both sides of the railway track and moved to both sides of the sleeper to be replaced. Place the new sleeper above the two guiding rails 221. For the sleeper to be replaced, after cleaning the buffer ballast around and under it, place the side of the auxiliary frame 4 close to the connecting frame 2 under the sleeper. Output by the motor A21 to drive the screw rod 211 to rotate, and then drive the sliding plate 22 to drive the guiding rail 221 to move forward, so that the bearing plate 223 moves under the sleeper. Subsequently, output by the cylinder A31 and the cylinder B441 simultaneously to lift the entire frame 1, and at the same time make the bearing plate 223 and the auxiliary frame 4 approach or directly contact the lower part of the sleeper. At this time, disassemble the connecting bolts between the sleeper and the railway track, and the sleeper falls on the surfaces of the bearing plate 223 and the auxiliary frame 4. Then the cylinder A31 and the cylinder B441 contract, and the entire device moves down. Then, through the output of the motor A21, the sliding plate 22 can drive the guiding rail 221 to continue to move forward, and push the old sleeper under the railway track to the side of the auxiliary frame 4 through the baffle 222. During this process, the new sleeper on the surface of the guiding rail 221 will also move synchronously under the frame 1, that is, under the railway track. While pushing out the old sleeper, the new sleeper moves in synchronously. The old sleeper is pushed onto the rotating shaft 41 on the surface of the auxiliary frame 4 to reduce friction. After the old sleeper is completely pushed out, the new sleeper is in place. Use track bolts to connect the new sleeper to the railway track and re-lay the buffer ballast to complete the entire process of sleeper handling and replacement.

[0048] Specifically, another usage method is: Push the new sleeper onto the rotating shaft 41 on the surface of the auxiliary frame 4, and do not place a sleeper on the surface of the guiding rail 221. Output by the motor A21 to drive the sliding plate 22 to move towards the direction of the old sleeper, so that the baffle 222 can drive the guiding rail 221 to rotate and unfold when blocked by the old sleeper, and make the slider 231 compress the spring 232. Until the baffle 222 is no longer blocked by the old sleeper, the resilience of the spring 232 drives the guiding rail 221 in contact with the slider 231 to return to the normal position. The guiding rail 221 moves under the old sleeper. At this time, connect one end of a steel wire rope, a steel chain or other ropes with sufficient strength to the positioning ring 225 on the surface of the baffle 222, and the other end to the sleeper bolt on the surface of the new sleeper, so that one end of the new sleeper is placed on the surface of the bearing plate 223. At this time, output by the cylinder A31 and the cylinder B441 to lift the entire device, and the guiding rail 221 contacts or approaches the lower part of the old sleeper. After disassembling the track bolts of the old sleeper, the old sleeper falls on the surface of the guiding rail 221. Then the cylinder A31 and the cylinder B441 contract to lower the height of the device. Reverse the motor A21 to move the old sleeper outwards, and at the same time the new sleeper is driven by the steel wire rope or steel chain to be pulled into the railway track. After disassembling the steel wire rope or steel chain, connect the new sleeper to the railway track with track bolts.

The above specific implementation manners are merely illustrative rather than restrictive.
