[0001] The utility model relates to the technical field of mechanical equipment, in particular to an RGV trolley track changing device based on a horizontal guide rail. Background Art

[0002] Traditional RGV tracks are generally straight reciprocating or circular tracks. Some RGVs with steering functions all use special track-changing devices on the tracks to achieve track-changing operations for the RGV trolleys. Although the establishment of a special track-changing device has achieved track-changing work, it has increased equipment costs and cannot guarantee the smooth completion of the track-changing work. Utility Model Content

[0003] The purpose of the present utility model is to overcome the deficiencies of the above-mentioned prior art and to provide an RGV trolley track changing device based on a horizontal guide rail. The track changing operation is realized by the steering device of the RGV itself, and no additional track changing device is required to be added to the track. Especially when multiple vehicles are operating in a queue, the RGV with its own track changing device can perform the track changing operation without stopping and waiting, thereby improving the operating efficiency of the RGV.

[0009] Each side of the chassis wheel bridge is equipped with two track guide wheels, and each side of the steering sliding plate is equipped with two steering guide wheels.

[0010] The steering guide wheel is slidably connected to the straight track.

[0017] With reference to the figures, the present invention specifically adopts the following implementation mode: it includes a track base plate 15, a branch track 16 and a straight track 13, the track base plate 15 is connected to the branch track 16, a straight track 13 is provided on the branch track 16, and a steering track switching mechanism 17 is provided on the straight track 13. There are two steering track switching mechanisms 17, and the two steering track switching mechanisms 17 are connected through the vehicle body cross beam 11. The two ends of the vehicle body cross beam 11 are respectively connected to the corresponding steering track switching mechanisms 17 by bolts. The steering track switching mechanism 17 includes a chassis wheel bridge 1, a steering screw module 2, and a steering sliding plate 6. The top of the steering sliding plate 6 is bolted to the vehicle body crossbeam 11, and the bottom of the steering sliding plate 6 is fixedly connected to the steering screw module 2. The steering screw module 2 is fixed to the chassis wheel bridge 1. One side of the chassis wheel bridge 1 is connected to the track guide wheel 3 via screws. The top of the chassis wheel bridge 1 is screwed to the linear guide 7, which is connected to the guide rail slider 8. The guide rail slider 8 is screwed to the steering sliding plate 6. A steering guide wheel 4 is installed on one side of the steering sliding plate 6. The limit sensor 5 is screwed to the chassis wheel bridge 1. The steering screw module 2 includes a screw slider 9 module, which is screwed to the steering sliding plate 6. The screw slider 9 is connected to one end of the motor shaft direct-connecting screw, and the other end of the motor shaft direct-connecting screw is connected to the output end of the drive motor. The drive motor is connected to the controller via a guide. Two track guide wheels 3 are mounted on each side of the chassis wheel bridge 1, and two steering guide wheels 4 are mounted on each side of the steering sliding plate 6. The steering guide wheels 4 are slidably connected to the straight track 13. The track guide wheels 3 are slidably connected to the sidewalls of the branch track 16. Straight track guide strips 14 are mounted on the branch track 16. A track turning guide strip 10 is installed at the top of the branch track 16 at the turn, and a vertical curve guide plate 12 is installed vertically at the turn of the branch track 16.

[0018] This RGV trolley track changing device based on horizontal guide rails must be installed before use. The steering screw module 2, track guide wheel 3, limit sensor 5 and linear guide rail 7 are all connected and installed with the chassis wheel bridge 1 through screws. The guide rail slider 8 and steering guide wheel 4 are installed on the steering sliding plate 6 through screws. The steering screw module 2 includes a screw slider 9 module. The screw slider 9 is connected to the steering sliding plate 6 through screws. The slidable steering sliding plate 6 contains a steering slider 6 that drives the steering slide 6 to perform linear motion through the steering screw module 2.

[0019] When the horizontal guide rail-based RGV trolley track changing device is used for steering, the controller sends a signal to the motor driver, which drives the motor to rotate. The lead screw directly connected to the motor shaft drives the lead screw slider 9 to reciprocate linearly, and the lead screw slider 9 drives the steering slide plate 6 to move, thereby causing the steering slide plate 6 to move to the left or right along the linear guide rail 7.

[0020] When the limit sensor 5 detects that the steering sliding plate 6 moves to the specified position, the drive motor stops rotating, and the limit sensor 5 sends a signal to the controller to feed back the position status of the steering sliding plate 6.

[0021] The chassis wheel bridges 1 of the two steering track switching mechanisms 17 are both equipped with steering screw modules 2, limit sensors 5 and steering sliding plates 6. When the two steering sliding plates 6 move to the same side at the same time, the steering operation is completed.

[0022] Track straight guide bars 14 are installed on the inner and outer upper edges of the track switch 16. Their function is to constrain the steering guide wheel 4 of the steering track switching mechanism 17, so that the steering track switching mechanism 17 moves along the direction of the straight guide bar 14, and then drives the entire steering track switching mechanism 17 to complete the steering, and controls the movement direction of the entire vehicle body cross beam 11 by limiting the travel direction of the steering guide wheel 4.

[0023] When the steering track-changing mechanism 17 turns, the track turning guide strip 10 limits the steering guide wheel 4 , and the steering guide wheel 4 slides along the track turning guide strip 10 and completes the turning work.

[0024] Both the track turning guide strip 10 and the track straight guide strip 14 play a role in limiting and guiding the steering guide wheel 4, preventing the steering track switching mechanism 17 from deviating from the track during travel, causing derailment or rollover.

[0025] The two steering track switching mechanisms 17 are connected through the vehicle body cross beam 11, which improves the stability of the steering track switching mechanism 17. When the two ends of the vehicle body cross beam 11 are connected to the steering track switching mechanism 17 through a single bolt, it is a flexible connection and will not limit the turning of the steering track switching mechanism 17.

[0026] The designed track guide wheel 3 contacts the two side walls of the switch track 16 and is connected in a smooth sliding manner to assist the steering guide wheel 4 in straight-line or turning track changing.

[0027] In summary, this horizontal guide rail-based RGV trolley track-changing device has a simple structure and is easy to use. Its integrated RGV body-mounted track-changing device improves vehicle throughput efficiency during multi-vehicle operations. Furthermore, if an RGV fails, the system can be quickly restored to operation by removing the faulty RGV. In contrast, a track-based track-changing device requires all RGVs to stop and wait for the faulty RGV to recover before continuing operation.
