Description

TECHNICAL FIELD

[0002] Track maintenance refers to various track maintenance operations for ensuring good track conditions and enabling trains to run safely, smoothly and uninterruptedly at the specified speed, which includes track renewal and repair for restoring the performance of various track components, and regular maintenance work for preventing and eliminating deformation and diseases of tracks under the influence of train power and other factors.

[0003] In the process of track maintenance operation, in order to ensure the integrity and smoothness of the track structure, the steel rail needs to be welded and repaired, among which the aluminothermic welding is the current mainstream welding process. After the aluminothermic welding is completed, high-temperature metal welding bumps will be formed at the welded joint part, and a bump pushing machine needs to be used for cutting to facilitate the subsequent polishing process. However, since the metal welding bump after cutting still maintains a high residual temperature, the current operation process mainly relies on manual transportation of the bump pushing machine and the high-temperature welding bump, which has significant occupational safety hazards, especially the high risk of burns for the operators.

The sliding hole 508 is formed through both sides of the braking block 507, and the braking block 507 is slidably connected to the surface of the guide column 506 through the sliding hole 508. The braking motor 509 is fixedly installed on one side of the braking seat 502.

[0034] Working principle: When in use, the drive motor 109 is started to drive the track wheel 110 to roll, thereby realizing the operation of the device on the track surface. After the device is moved to the track docking point and the position is adjusted, the drive motor 109 is turned off. Then, the brake seat 502 is flipped down to separate the armature plate 505 from the magnet plate 304. Then, the brake motor 509 is started, which drives the threaded rod 510 to rotate. When the threaded rod 510 rotates, it pushes the two brake blocks 507 to slide to both sides, thereby making the mating groove 512 lock onto the track surface, thus realizing the braking and positioning of the device. After the aluminothermic welding is completed and the mold and other equipment are removed, the protective seat 116 above the corresponding side track is activated. The sensor 302 continuously feeds back position information and adjusts the position. During adjustment, the transverse motor 103 drives the transverse seat 104 to rotate, thereby continuously adjusting the angle of the transverse seat 104 until the first isolation pad 201 and the second isolation pad 207 are aligned with the track. Then, the fifth hydraulic cylinder 208 is activated to retract, causing the fifth hydraulic cylinder 208 to drive the moving shovel head 204 to slide towards the side closer to the first isolation pad 201 via the sliding pusher 209. Then, the first hydraulic cylinder 112, the second hydraulic cylinder 113, the third hydraulic cylinder 114, and the fourth hydraulic cylinder 115 are driven to make the moving shovel head 204 and the fixed shovel head 205 cover the surface of the track at both ends. And fit together, while ensuring that the metal weld bead is located between the moving shovel head 204 and the fixed shovel head 205, and then activate the electromagnetic lock 213. The electromagnetic lock 213 drives its output end to extend out of the receiving hole 215, so that the rubber anti-slip head 214 is pressed against the track surface, thereby locking the push mechanism. The extension and retraction of the first hydraulic cylinder 112 will adjust the angle between the first robotic arm 105 and the transverse seat 104, the extension and retraction of the second hydraulic cylinder 113 will adjust the angle between the second robotic arm 106 and the first robotic arm 105, the extension and retraction of the third hydraulic cylinder 114 will adjust the angle between the third robotic arm 107 and the second robotic arm 106, and the extension and retraction of the fourth hydraulic cylinder 115 will adjust the angle between the first isolation pad groove block 201 and the third robotic arm 107. After the movable shovel head 204 and the fixed shovel head 205 cover the track surfaces at both ends, the fifth hydraulic cylinder 208 is activated to extend, causing the fifth hydraulic cylinder 208 to drive the movable shovel head 204 to move away from the first isolation pad 201 via the sliding pusher 209, until the movable shovel head 204 and the fixed shovel head 205 are in contact. At this time, the movable shovel head 204 cuts and stores the metal weld beads on the track surface between the two side sealing plates 203, the two edge sealing pieces 212, the movable shovel head 204, and the fixed shovel head 205, and then... The electromagnetic lock 213 drives its output end to retract and retract the receiving hole 215, thereby releasing the locking of the push-button mechanism. Then, it drives the first hydraulic cylinder 112, the second hydraulic cylinder 113, the third hydraulic cylinder 114, and the fourth hydraulic cylinder 115 to lift the push-button mechanism and the internal metal weld bead. This drives the transverse motor 103 to rotate the transverse seat 104, allowing the metal weld bead to be transported to a position away from the track weld point for subsequent disengagement work, thus ensuring that the track weld point can be used for subsequent operations.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
