The advantage of this utility model is that by arranging the track-changing mechanism, the transportation range of the electric trolley is effectively increased, thereby improving work efficiency, and by arranging the control mechanism, it is ensured that there will be no large error in the docking between the track-changing track and the second track, thereby avoiding the situation where the electric trolley derails and falls and causes injuries to the staff, thereby improving safety.

[0004] The above-mentioned and existing technologies have the following defects: during the operation of the electric trolley, in order to ensure that the track changing track can rotate normally to change tracks, it is necessary to keep a certain distance between the track changing track and the base track. At this time, there will be a large gap between the track changing track and the rack of the base track, resulting in the power gear of the electric trolley being unable to engage with the track changing rack when transitioning from the rack of the base track to the track changing rack of the track changing track, making it inconvenient to change tracks.

[0005] Therefore, a track transportation device that is convenient for track changing is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that when the power gear of the electric trolley transitions from the rack of the basic track to the track changing rack of the track changing track, the power gear cannot engage with the track changing rack, making it inconvenient to change tracks, and to propose a track transportation device that is convenient for track changing.

[0007] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a track transport device that is convenient for track changing, comprising a suspension frame, a change track and a sliding frame, wherein a plurality of fixed rails are fixedly mounted on the lower surface of the suspension frame, a first rack is fixedly mounted on the lower surface of the fixed rail, a second rack is fixedly mounted on the lower surface of the change track, a transport vehicle is fixedly connected to the lower end of the sliding frame, a roller is rotatably connected to the upper end of the sliding frame, an outer circumferential surface of the roller abuts against the surface of the change track, a transmission gear meshed with the second rack is rotatably connected to the inside of the sliding frame, a drive motor is fixedly mounted on the side wall of the sliding frame, an output end of the drive motor is fixedly connected to the transmission gear, and further comprising:

[0008] A track changing structure is provided on the lower surface of the suspension frame, and is used to drive the track changing of the changing track. The track changing structure includes a bracket fixedly mounted on the lower surface of the suspension frame, a driven gear and a driving gear for adjusting the angle of the changing track, and a clamping ring and a clamping plate for adjusting the height of the changing track;

[0013] The effect achieved by the above components is: controlling the output end of the first electric push rod to extend, the clamping ring will drive the clamping plate to move upward, the movement of the clamping plate will drive the transmission rod to move, the movement of the transmission rod will drive the changing track, so that the changing track is higher than the fixed track, and then turning on the stepper motor, the output end of the stepper motor will rotate to drive the driving gear to rotate, the driving gear will rotate to drive the driven gear, the rotating ring will follow the driven gear to rotate to drive the transmission rod to rotate, and the transmission rod will drive the changing track to rotate, thereby adjusting the direction of the changing track. When the changing track is aligned with the appropriate track, the stepper motor is turned off, and the output end of the first electric push rod is controlled to contract. At this time, the changing track will move downward until the changing track is stably aligned with the fixed track.

[0014] Preferably, the outer circumferential surface of the clamping ring is rotatably connected to a rotating plate, the surface of the bracket is rotatably connected to a connecting plate, and the connecting plate is rotatably connected to the rotating plate.

[0015] The effect achieved by the above components is that the cooperation between the rotating plate and the connecting plate can limit the position of the clamping ring, thereby preventing the clamping ring from rotating with the clamping plate and causing damage to the first electric push rod.

[0016] Preferably, the output end of the second electric push rod is fixedly equipped with a round tube, the inner wall of the round tube is slidably connected to a slider, one end of the slider is fixedly equipped with a limit plate, the limit plate slides through the changing track, and the surface of the fixed track is provided with a limit groove adapted to the limit plate.

[0018] Preferably, a positioning groove is provided on the surface of the limiting plate, and a positioning block adapted to the positioning groove is fixedly mounted on the inner wall of the limiting groove.

[0019] The effect achieved by the above components is that the positioning groove and the positioning block are engaged with each other to prevent the limiting plate from sliding further downward.

[0021] The effect achieved by the above components is: when the limit plate is aligned with the limit groove, the first spring will immediately stretch, the slider will slide with the help of the elastic force of the first spring, and the sliding of the slider will cause the limit plate to automatically insert into the inner wall of the limit groove.

[0022] Preferably, the surface of the limiting plate is provided with an inclined surface.

[0023] The effect achieved by the above components is that after the inclined surface of the limit plate contacts the fixed track, the fixed track will squeeze the inclined surface of the limit plate, and the limit plate will automatically slide along the changing track due to the squeezing, thereby facilitating operation.

[0024] Preferably, the upper end of the blocking rod is fixedly connected to a pull plate, the second spring is sleeved on the outer circumferential surface of the blocking rod, and the two ends of the second spring are respectively fixedly connected to the pull plate and the changing track.

The sliding of the baffle rod will drive the pull plate to slide. At this time, the second spring will pull the pull plate with the help of elastic force, thereby increasing the resistance of the baffle rod to the roller.

[0026] Preferably, a damping plate is fixedly mounted on the upper surface of the direction-changing track, and the damping plate slides through the pull plate.

[0027] The effects achieved by the above components are: the damping plate can damp the pulling plate, thereby preventing the blocking rod from bouncing back and forth due to the elastic force of the first spring.

[0028] Preferably, a strip plate is slidably sleeved on the surface of the transmission rod, the strip plate is located above the pull plate, the cross section of the strip plate is "H" shaped, and an extension rod is fixedly assembled on the upper surface of the strip plate.

[0029] The effect achieved by the above components is: the movement of the strip plate will drive the extension rod to move, and the extension rod will first rest against the surface of the driven gear. As the first electric push rod continues to extend, the pull plates at both ends of the changing track will be blocked by the strip plate. At this time, the lower end of the barrier rod will be lower than the central axis of the roller located at a high place. Therefore, when the subsequent track changing operation is performed, the barrier rods at both ends of the changing track can prevent the roller from sliding from the surface of the changing track, causing the transport vehicle to fall.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are:

[0031] 1. In the present invention, by setting a track-changing structure, during the use of the transport vehicle, the track-changing operation is performed by first lifting the changing track and then rotating it to adjust the direction. This can ensure that the fixed track and the changing track can offset each other during operation, thereby reducing the distance between the first rack and the second rack, ensuring that the transmission gear can normally transition between the first rack and the second rack, thereby facilitating track changing.

[0032] 2. In the present invention, by setting a limiting structure, when the limiting plate is inserted into the inner wall of the limiting groove, the limiting groove and the limiting plate cooperate to limit the position of the turning track, thereby preventing the turning track from being misaligned with the fixed track due to the vibration generated by the transport vehicle during travel, thereby ensuring that the turning track is stably aligned with the fixed track.

[0033] 3. In the present invention, by setting a deceleration structure, when the transport vehicle needs to change tracks, the second spring can use the elastic force to increase the resistance of the barrier rod to the roller. By delaying the movement of the roller, the transport vehicle can be decelerated and stopped quickly, which is convenient for subsequent rapid track change operations.

[0047] A swivel 12 is rotatably connected in the bracket 11, and a transmission rod 13 is vertically slidably passed through the swivel 12. A driven gear 14 is fixedly assembled at the lower end of the swivel 12. A stepper motor 15 is fixedly assembled on the surface of the bracket 11. The output end of the stepper motor 15 is fixedly connected to the driving gear 16. The driven gear 14 is meshed with the driving gear 16. A first electric push rod 17 is fixedly assembled on the surface of the bracket 11. A snap ring 18 is fixedly assembled at the output end of the first electric push rod 17. A card plate 19 is fixedly assembled at the upper end of the transmission rod 13. The card plate 19 is rotatably mounted on the inner wall of the snap ring 18 to control the extension of the output end of the first electric push rod 17. The snap ring 18 will drive the card plate 19 to move upward. The card plate 19 The movement will drive the transmission rod 13 to move, and the movement of the transmission rod 13 will drive the changing track 4, so that the changing track 4 is higher than the fixed track 2. Then the stepper motor 15 is turned on, and the output end of the stepper motor 15 rotates to drive the driving gear 16 to rotate. The rotation of the driving gear 16 will drive the driven gear 14 to rotate. The swivel 12 follows the driven gear 14 to rotate, which will drive the transmission rod 13 to rotate. The transmission rod 13 will drive the changing track 4 to rotate, thereby adjusting the direction of the changing track 4. When the changing track 4 is aligned with the appropriate track, the stepper motor 15 is turned off, and the output end of the first electric push rod 17 is controlled to retract. At this time, the changing track 4 will move downward until the changing track 4 is stably aligned with the fixed track 2.

[0048] The outer circumferential surface of the retaining ring 18 is rotatably connected to a rotating plate 20, and the surface of the bracket 11 is rotatably connected to a connecting plate 21. The connecting plate 21 is rotatably connected to the rotating plate 20. The rotating plate 20 and the connecting plate 21 cooperate to limit the position of the retaining ring 18, preventing the retaining ring 18 from rotating with the retaining plate 19 and causing damage to the first electric push rod 17.

[0049] The output end of the second electric push rod 22 is fixedly equipped with a round tube 23, and the inner wall of the round tube 23 is slidably connected with a slider 24. One end of the slider 24 is fixedly equipped with a limit plate 25, and the limit plate 25 slides through the changing track 4. The surface of the fixed track 2 is provided with a limit groove 26 that is compatible with the limit plate 25. The movement of the output end of the second electric push rod 22 will drive the movement of the round tube 23, and the movement of the round tube 23 will drive the movement of the slider 24. The movement of the slider 24 will drive the limit plate 25 to move. When the limit plate 25 is inserted into the inner wall of the limit groove 26, the limit groove 26 and the limit plate 25 cooperate to limit the position of the changing track 4.

[0050] A positioning groove 27 is formed on the surface of the limiting plate 25 , and a positioning block 28 adapted to the positioning groove 27 is fixedly mounted on the inner wall of the limiting groove 26 . The positioning groove 27 and the positioning block 28 engage to prevent the limiting plate 25 from sliding further downward.

[0051] A first spring 29 is fixedly assembled on the inner wall of the circular tube 23, and one end of the first spring 29 is fixedly connected to the slider 24. When the limit plate 25 is aligned with the limit groove 26, the first spring 29 will immediately extend, and the slider 24 will slide with the help of the elastic force of the first spring 29. The sliding of the slider 24 will cause the limit plate 25 to automatically insert into the inner wall of the limit groove 26.

[0052] The surface of the limiting plate 25 is provided with an inclined surface. When the inclined surface of the limiting plate 25 contacts the fixed track 2, the fixed track 2 will squeeze the inclined surface of the limiting plate 25. The limiting plate 25 will automatically slide along the changing track 4 due to the squeezing, thereby facilitating operation.

[0053] The upper end of the baffle rod 30 is fixedly connected to the pull plate 31, and the second spring 32 is sleeved on the outer circumference of the baffle rod 30. The two ends of the second spring 32 are respectively fixedly connected to the pull plate 31 and the changing track 4. After the roller 8 contacts the baffle rod 30, the roller 8 will squeeze the baffle rod 30, and the baffle rod 30 will slide upward along the changing track 4. The sliding of the baffle rod 30 will drive the pull plate 31 to slide. At this time, the second spring 32 will pull the pull plate 31 with the help of elastic force, thereby increasing the resistance of the baffle rod 30 to the roller 8.

[0054] A damping plate 33 is fixedly mounted on the upper surface of the change track 4 , and the damping plate 33 slides through the pull plate 31 . The damping plate 33 can damp the pull plate 31 , thereby preventing the blocking rod 30 from bouncing back and forth due to the elastic force of the first spring 29 .

[0055] The surface of the transmission rod 13 is slidingly covered with a strip plate 34, which is located above the pull plate 31. The cross-section of the strip plate 34 is "H"-shaped, and the upper surface of the strip plate 34 is fixedly equipped with an extension rod 35. The movement of the strip plate 34 will drive the extension rod 35 to move, and the extension rod 35 will first rest against the surface of the driven gear 14. As the first electric push rod 17 continues to extend, the pull plates 31 at both ends of the changing track 4 will be blocked by the strip plate 34. At this time, the lower end of the blocking rod 30 will be lower than the central axis of the roller 8 located at a high place. Therefore, when the track changing operation is performed subsequently, the blocking rods 30 at both ends of the changing track 4 can prevent the roller 8 from sliding from the surface of the changing track 4, causing the transport vehicle 7 to fall.

[0056] Its overall working principle is that when the transport vehicle 7 is used, the drive motor 10 is turned on, and the rotation of the output end of the drive motor 10 drives the transmission gear 9 to rotate, and the transmission gear 9 moves along the surface of the first rack 3, thereby driving the sliding frame 6 to move, and the sliding frame 6 drives the transport vehicle 7 to move. When the transport vehicle 7 needs to change tracks, the drive motor 10 is controlled to move the sliding frame 6 to the redirecting track 4. In this process, since the redirecting track 4 can be against the surface of the fixed track 2, the distance between the first rack 3 and the second rack 5 is small, so that the drive gear can be normally transitioned to the second rack 5, and then the roller 8 The pull plate 31 is then pulled back to the stopper 33 and the second spring 32 is pulled back to the stopper 33. The second spring 32 is pulled back to the stopper 33 and the second spring 32 is pulled back to the stopper 33. The second spring 32 is pulled back to the stopper 33 and the second spring 32 is pulled back to the stopper 33. The second spring 32 is pulled back to the stopper 33 and the second spring 32 is pulled back to the stopper 33. The second spring 32 is pulled back to the stopper 33 and the second spring 32 is pulled back to the stopper 33.

[0057] When the transport vehicle 7 stops, the output end of the second electric push rod 22 is controlled to retract, and the second electric push rod 22 will drive the round tube 23 to move. The slider 24 follows the movement of the round tube 23 to make the limit plate 25 slide out from the inner wall of the limit groove 26. Then the output end of the first electric push rod 17 is controlled to extend, and the clamping ring 18 will drive the card plate 19 to move upward. The movement of the card plate 19 will drive the transmission rod 13 to move. The movement of the transmission rod 13 will drive the changing track 4, so that the changing track 4 is higher than the fixed track 2. In this process, the strip plate 34 will move in the direction close to the driven gear 14. The movement of the strip plate 34 will drive the extension rod 35 to move. The extension rod 35 will first rest on the surface of the driven gear 14. As the first electric push rod 17 continues to extend The pull plates 31 at both ends of the changing track 4 will be blocked by the strip plates 34. At this time, the lower end of the blocking rod 30 will be lower than the central axis of the roller 8 located at the higher position. Therefore, when the track changing operation is performed later, the blocking rods 30 at both ends of the changing track 4 can prevent the roller 8 from sliding off the surface of the changing track 4, causing the transport vehicle 7 to fall. Then, the stepping motor 15 is turned on and the output end of the second electric push rod 22 is controlled to extend to reset the limit plate 25. At the same time, the rotation of the output end of the stepping motor 15 will drive the driving gear 16 to rotate, and the rotation of the driving gear 16 will drive the driven gear 14 to rotate. The swivel 12 follows the rotation of the driven gear 14 to drive the transmission rod 13 to rotate, and the transmission rod 13 will drive the changing track 4 to rotate. The turning plate 20 and the connecting plate 21 cooperate to limit the position of the clamping ring 18, thereby preventing the clamping ring 18 from rotating with the clamping plate 19 and causing damage to the first electric push rod 17. When the turning track 4 is aligned with the appropriate track, the stepping motor 15 is turned off to control the output end of the first electric push rod 17 to retract. At this time, the turning track 4 will move downward. During this process, the turning track 4 will drive the limit plate 25 to move, and the inclined surface of the limit plate 25 will contact the fixed track 2. The fixed track 2 will squeeze the inclined surface of the limit plate 25. The limit plate 25 will automatically slide along the turning track 4 due to the squeezing, and the sliding of the limit plate 25 will drive the slider 24 to slide along the inner wall of the round tube 23. When the slider 24 moves, the sliding of the slider 24 will compress the first spring 29. When the limit plate 25 is aligned with the limit groove 26, the first spring 29 will immediately extend, and the slider 24 will slide with the elastic force of the first spring 29. The sliding of the slider 24 will cause the limit plate 25 to automatically insert into the inner wall of the limit groove 26. The limit groove 26 and the limit plate 25 cooperate to limit the position of the change track 4. At the same time, the positioning groove 27 will engage with the positioning block 28 to prevent the limit plate 25 from sliding further downward, avoiding the change track 4 from being misaligned with the fixed track 2 due to the vibration generated when the transport vehicle 7 is traveling, so that the change track 4 is stably aligned with the fixed track 2. After that, the transport vehicle 7 can be stably moved to the other fixed track 2 to complete the track changing operation.
