[0002] The safe, reliable and stable operation of the car tipping system directly affects the unloading efficiency of bulk cargo on trains, and the alignment of the railway tracks directly affects the safety of train carriages. The transfer platform frequently travels between the loaded and empty lines, and the alignment problem between the platform track and the ground track is particularly prominent; due to factors such as temperature, environment, wear and aging, the positioning limit of the transfer platform needs to be frequently adjusted and calibrated. Because the positioning limiter is installed next to the walking track of the car moving platform at the bottom of the car moving pit, there is a great risk of personnel being squeezed and injured during the limit adjustment test. In order to reduce the operation risk, a simple limit adjustment requires a cumbersome and complicated operation process with a long processing cycle, which seriously affects the operation efficiency of the tipping machine system; in rainy and snowy seasons, the positioning limiter of the car moving platform is installed at the bottom of the car moving platform, which is very easy to cause signal circuit failure or even signal confusion due to the influence of rain, snow or other accumulated water, affecting the operation of the entire tipping machine system and even causing serious equipment damage; the positioning limiter of the car moving platform is installed next to the walking track of the car moving platform, which is far away from the end of the car moving platform surface track, and cannot guarantee the reliable alignment of the surface track and the ground train track.
[0003] In the prior art, the positioning limit of the car moving platform is installed next to the walking track of the car moving platform at the bottom of the car moving pit. During the positioning limit adjustment test, the movement space of personnel in the car moving pit is limited. During the movement of the car moving platform back and forth, the risk of personnel being squeezed or crushed is high, affecting the safe operation of personnel; the positioning limit of the car moving platform is installed at a low position, which is easily soaked by rain, snow or accumulated water, causing limit switch failure or signal circuit short circuit, resulting in signal confusion, affecting the operation of the rectification tipping machine system; the positioning limit installation position of the car moving platform is far away from the end of the table track, and cannot accurately reflect the alignment of the table track and the ground train track.

[0025] Working principle: First, the power device drives the transfer platform body 4 to move through the roller 7 so that the imported rail 1 and the table rail 5 are in the same position. During the movement, the imported rail 1 and the table rail 5 are positioned and aligned under the action of the positioning limit device 2. The limiting device of the transfer platform body 4 is composed of a limit stop installed on the side of the transfer platform close to the ground import rail and the export rail, and a deceleration limit switch and a positioning limit switch installed on the foundation. There are two groups in total, one group for the heavy vehicle line and one group for the empty vehicle line; the function of the limiting device is to limit the position of the transfer platform when it reaches the heavy vehicle line or the empty vehicle line, so that the rail on the transfer platform is aligned with the foundation rail; when the transfer platform approaches the empty vehicle line or the heavy vehicle line, the transfer platform first senses (or triggers) the deceleration limit switch The switch signal acts on the power device of the car moving platform through the control logic, so that its speed gradually tends to zero. At this time, the car moving platform senses (or triggers) the positioning limit switch signal, stops the output of the power device of the car moving platform, and the surface rail of the car moving platform is just aligned with the ground rail. Then the empty car moves to the car moving platform body 4 through the import rail 1 and the surface rail 5. If the car moving platform is to return, the hydraulic mechanism and the electromagnetic mechanism can be activated by the control button to open the braking system of the car moving platform. The car moving platform moves under the action of the power device, the support frame 6 and the roller 7 to one end of the exit rail 9, and then is positioned under the action of the positioning limit device 2, and then the carriage is pushed out of the outside of the car moving platform body 4 through the external device (empty car shunting machine) to complete the migration of the carriage.
