TECHNICAL FIELD

[0001] The present application relates to the field of track laying technology, in particular to a sleeper laying device for rail transit. BACKGROUND

[0002] Sleeper laying is a core link of rail transit construction, which forms a basic structure for supporting steel rails by fixing sleepers at a designed interval on a track bed. The core function is to transfer train load, stabilize the track and buffer vibration. The material has gone through wooden sleepers and steel sleepers, and is now mainly concrete sleepers. New sleepers such as elastic and plastic sleepers are adapted to the needs of vibration reduction and environmental protection. Through systematic design and technological innovation, sleeper laying is continuously developing towards high efficiency, intelligence and green, providing a solid foundation for the safety and sustainable operation of modern rail transit.

[0003] However, we have found in actual life that with the passage of time, individual sleepers may age, crack or settle, affecting the geometric shape and carrying capacity of the track. At this time, the sleepers need to be replaced or relaid to restore the smoothness and stability of the track.

When the driving gear 94 rotates, the transmission belt 102 arranged outside the support plate 81 will drive the transmission gear 101 to rotate synchronously through the transmission tooth grooves 103 inside the transmission belt 102, so that the transmission belt 102 operates under the action of the driving gear 94 and the transmission gear 101. When the transmission belt 102 moves, the plurality of ballast plates 3 arranged outside the transmission belt 102 will move synchronously, and the ballast plates 3 clean the ballast around the rail 1, so that the obstacles above the sleeper body 2 are removed, providing a good operation space for subsequent replacement of the sleeper.

The purpose is to achieve rapid switching and precise positioning of power between different stations, thereby ensuring that the staff can flexibly adjust the equipment according to actual needs, improving overall work efficiency and operation convenience.

[0049] In use, when the staff needs to replace the single sleeper body 2 at the bottom of the rail 1, the control handle 83 is pushed, the support plate 81 is driven to move through the control handle 83, the universal wheel 82 arranged at the bottom of the support plate 81 can change the moving direction in real time according to the operation of the staff on the control handle 83, and the pad 84 arranged at the top of the support plate 81 and located at the bottom of the bearing plate 4 can avoid that the parts below the bearing plate 4 are damaged when the sleeper body 2 is placed on the top of the bearing plate 4, when the support plate 81 reaches one end of the sleeper body 2 to be replaced through the universal wheel 82, the drive motor 91 can be started, when the drive motor 91 operates, the drive rod 92 arranged at the output end of the drive motor 91 rotates, and the drive gear 94 arranged at one end of the drive rod 92 rotates under the action of the drive rod 92, when the drive gear 94 rotates, the transmission belt 102 arranged outside the support plate 81 rotates synchronously through the transmission gear slot 103 inside the transmission belt 102, so that the transmission belt 102 operates under the action of the drive gear 94 and the transmission gear 101, when the transmission belt 102 moves, the plurality of ballast plates 3 arranged outside the transmission belt 102 moves synchronously, the ballast around the rail 1 is cleaned through the ballast plate 3, so that the obstacles above the sleeper body 2 are removed, providing a good operation space for subsequent replacement of the sleeper, when the plurality of ballast plates 3 moves under the action of the transmission belt 102, the ballast around the rail 1 can be continuously pushed away to one side, and the ballast is accumulated away from the sleeper body 2, thereby effectively widening the work area and improving the replacement efficiency, the plurality of grooves 7 opened on the ballast plate 3 can effectively increase the friction between the ballast plate 3 and the ballast, prevent the ballast from slipping during pushing, thereby ensuring the efficiency and stability of the ballast being pushed away, and the purpose of the bevels at both ends of the ballast plate 3 is to make the ballast plate 3 more smoothly cut into the ballast pile during movement, reduce resistance and improve work efficiency, and the bevel design also helps to avoid the phenomenon of jamming with the ballast when the ballast plate 3 is reset, further improving the reliability and stability of the device operation;

[0050] With the continuous operation of the transmission belt 102, the plurality of ballast plates 3 gradually push out the ballast under the rail sleeper body 2 to be replaced, exposing the bottom of the rail sleeper body 2, so that the rail sleeper body 2 is suspended at the bottom of the rail 1. It should be noted that after starting the driving motor 91, the worker needs to adjust the position of the support plate 81 through the control handle 83 to ensure that the plurality of ballast plates 3 can push away the ballast while slowly entering the working area at the bottom of the rail sleeper body 2 to be replaced. When the ballast plate 3 completely enters the bottom of the rail sleeper body 2 to be replaced, the worker can stop the operation of the driving motor 91 and appropriately adjust the position of the bearing plate 4 so that the rail sleeper body 2 to be replaced is located at the center of the bearing plate 4.

When the switching plate 133 descends, the plug plate 134 arranged at the bottom thereof will move downward together with it until the plug plate 134 is completely inserted into the insertion slot 137 at the top of the circular ring 135. During the process of inserting the plug plate 134 into the insertion slot 137, the connecting plate 139 will pass through the lock plate 1312 and press the inclined surface of the lock plate 1312, so that the lock plate 1312 slides in the auxiliary frame 1311 after being pressed and the locking spring 1314 starts to compress and store energy. As the connecting plate 139 continues to slide downward, when the connecting plate 139 completely passes through the lock plate 1312, the locking spring 1314 will quickly rebound, pushing the lock plate 1312 to slide forward and being clamped at the top of the connecting plate 139, so that the connecting plate 139 cannot slide upward, thereby achieving the locking of the switching plate 133. During the downward movement of the connecting plate 139, the switching spring 1315 arranged at the bottom of the connecting plate 139 will slowly store energy to provide elastic support for the subsequent resetting of the switching plate 133, while ensuring that the entire locking mechanism can still operate stably under complex working conditions. At this time, the plug plate 134 at the bottom of the switching plate 133 has been completely inserted into the corresponding insertion slot 137. At this time, the worker can start the driving motor 91 again. When the driving motor 91 operates at this time, the driving rod 92 will drive the rectangular plate 132 to rotate through the rectangular groove 131, thereby driving the switching plate 133 to rotate synchronously, so that the plug plate 134 located below the switching plate 133 rotates synchronously through the insertion slot 137. When the circular ring 135 rotates, the switching gear 136 arranged outside the circular ring 135 will rotate together with the circular ring 135. At this time,The inner ring of the bearing 138 arranged outside the switching plate 133 rotates synchronously with the rotation of the switching plate 133, and the outer ring is kept stationary through the connecting plate 139, so that the bearing 138 realizes stable transmission under the condition that the inner ring rotates and the outer ring is fixed. When the switching gear 136 rotates, the synchronous gear 121 engaged with the switching gear 136 also rotates.

[0051] When the synchronous gear 121 rotates, the synchronous gear 121 drives the synchronous belt 122 to rotate through the plurality of synchronous tooth grooves 123 on the synchronous belt 122, so that the plurality of lifting gears 114 used in cooperation with the synchronous belt 122 through the synchronous tooth grooves 123 rotate synchronously. In the process of synchronous rotation of the synchronous belt 122, the synchronous belt 122 is more stable in the transmission process because the two sides of the synchronous belt 122 are in contact with the cushion block 84, so that the plurality of lifting gears 114 always keep synchronous when rotating. When the lifting gear 114 rotates, the lifting rod 111 arranged at the shaft center of the lifting gear 114 also rotates. In the rotating process, the screw rod 113 connected with the lifting rod 111 through the internal threaded groove 112 of the lifting rod 111 moves upward along the axial direction of the lifting rod 111, so as to drive the carrier plate 4 arranged at the top of the screw rod 113 to rise. Because a plurality of screw rods 113 and a plurality of lifting rods 111 are arranged, the screw rod 113 at the shaft center of the lifting rod 111 can only move linearly along the axial direction and cannot rotate in the rotating process of the lifting rod 111, so as to ensure that the carrier plate 4 always keeps horizontal state in the rising process and cannot incline or shake. When the carrier plate 4 rises to the top and is in contact with the bottom of the waste and old sleeper body 2, the sleeper body 2 can be separated from the rail 1. The separated sleeper body 2 is stably held by the carrier plate 4. At this time, the worker can control the height and moving position of the carrier plate 4 through the control handle 83 and the driving motor 91, so as to replace the waste and old sleeper body 2. After the waste and old sleeper body 2 is away from the rail 1, the driving motor 91 is reversed to make the carrier plate 4 descend, so as to facilitate the waste and old sleeper body 2 to be placed on the ground or the transportation equipment. After the waste and old sleeper body 2 is placed, the worker can place the new sleeper body 2 above the carrier plate 4 and align the bottom of the new sleeper body 2 with the rail 1 again through the above operation. Then, the driving motor 91 is started to rotate in the forward direction to drive the carrier plate 4 to rise until the new sleeper body 2 is closely in contact with the rail 1, the installation is completed, the whole replacement process is efficient and accurate, the labor intensity is greatly reduced, and the safety and stability of the sleeper replacement are improved.
