Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation devices, and particularly to a rail transportation device facilitating rail change. Background Art

[0002] A monorail conveyor is a transportation device operating in a specific space. Its rails are installed at a high position, and the transportation device runs below the rails through a suspension device. It is commonly used in the painting production line, assembly line, etc. of factories, can make full use of the factory building space, and achieve three-dimensional conveying of materials.

[0003] In the prior art, there appears a patent document with the publication number CN216376263U. This patent document discloses a rail change device for a conveyor, including a rail body. A control mechanism is fixedly connected to the bottom of the rail body. A rail change mechanism is movably connected to the middle of the control mechanism. An electric trolley is movably connected to the bottom of the rail body. The rail change mechanism includes a rail change track, a rail change rack, a connection seat, a connection column, a limit disc, and a first gear. A rail change rack is arranged at the bottom of the rail change track. A connection seat is fixedly connected to the top of the rail change track. A connection column is fixedly connected to the top of the connection seat. The advantages of this utility model are as follows: By setting the rail change mechanism, the transportation range of the electric trolley is effectively increased, thereby improving work efficiency. By setting the control mechanism, it is ensured that there will be no large error in the docking between the rail change track and the second track, avoiding the situation that the electric trolley derails and falls, causing harm to the staff, and thus improving safety.

[0004] The above and prior art have the following defects: During the operation of the electric trolley, in order to ensure that the rail change track can rotate normally for rail change, it is necessary to keep a certain distance between the rail change track and the basic track. At this time, there will be a large gap between the rack of the rail change track and the basic track, resulting in that when the driving gear of the electric trolley transitions from the rack of the basic track to the rail change rack of the rail change track, the driving gear cannot mesh with the rail change rack, thus making it inconvenient to perform rail change.

[0005] Therefore, a rail transportation device facilitating rail change is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the drawback that when the driving gear of the electric trolley transitions from the rack of the basic track to the rail change rack of the rail change track, the driving gear cannot mesh with the rail change rack, thus making it inconvenient to perform rail change, and to propose a rail transportation device facilitating rail change.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A track transportation device facilitating track change, comprising a suspension frame, a steering track, and a sliding frame. A plurality of fixed tracks are fixedly assembled on the lower surface of the suspension frame. A first rack is fixedly assembled on the lower surface of the fixed track. A second rack is fixedly assembled on the lower surface of the steering 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. The outer circumferential surface of the roller abuts against the surface of the steering track. A transmission gear meshing with the second rack is rotatably connected inside the sliding frame. A driving motor is fixedly assembled on the side wall of the sliding frame. The output end of the driving motor is fixedly connected to the transmission gear. It further includes:

[0008] A track-changing structure disposed on the lower surface of the suspension frame for driving the steering track to change tracks. The track-changing structure includes a bracket fixedly installed on the lower surface of the suspension frame, a driven gear and a driving gear for adjusting the angle of the steering track, and a snap ring and a clamping plate for adjusting the height of the steering track.

[0009] A limiting structure disposed on the inner wall of the steering track for stably aligning the steering track with the fixed track. The limiting structure includes a second electric push rod fixedly installed on the inner wall of the steering track, a limiting plate for restricting the position of the steering track, and a limiting groove.

[0010] A deceleration structure disposed on the surface of the steering track for decelerating the transport vehicle. The deceleration structure includes a plurality of blocking rods slidably penetrating through the steering track and a second spring for increasing the resistance of the blocking rod to the roller.

[0011] The effects achieved by the above components are as follows: By setting the track-changing structure, during the use of the transport vehicle, the track-changing operation is carried out by first lifting the steering track and then rotating and adjusting its direction. This can ensure that the fixed track and the steering track can abut against 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, and thus facilitating track change. By setting the limiting structure, after the limiting plate is inserted into the inner wall of the limiting groove, the cooperation between the limiting groove and the limiting plate can restrict the position of the steering track, avoiding the situation where the steering track is misaligned with the fixed track due to the vibration generated when the transport vehicle is running, and further ensuring that the steering track is stably aligned with the fixed track. By setting the deceleration structure, when it is necessary to change the track of the transport vehicle, the second spring can increase the resistance of the blocking rod to the roller by means of elastic force. By delaying the movement of the roller, the transport vehicle can be decelerated and quickly stopped, facilitating subsequent rapid track-changing operations.

[0012] Preferably, a rotating ring is rotatably connected inside the bracket, a transmission rod vertically slides through the rotating ring, the driven gear is fixedly assembled at the lower end of the rotating ring, a stepper motor is fixedly assembled on the surface of the bracket, the output end of the stepper motor is fixedly connected to the driving gear, the driven gear meshes with the driving gear, a first electric push rod is fixedly assembled on the surface of the bracket, the clamping ring is fixedly assembled at the output end of the first electric push rod, the clamping plate is fixedly assembled at the upper end of the transmission rod, and the clamping plate is rotatably installed on the inner wall of the clamping ring.

[0013] The effects achieved by the above components are as follows: When the output end of the first electric push rod is controlled 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, and the movement of the transmission rod will drive the deflection track, making the deflection track higher than the fixed track. Then, the stepper motor is turned on. The rotation of the output end of the stepper motor will drive the driving gear to rotate, the rotation of the driving gear will drive the driven gear to rotate, the rotation of the rotating ring following the driven gear will drive the transmission rod to rotate, and the transmission rod will drive the deflection track to rotate, thereby adjusting the orientation of the deflection track. When the deflection 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 deflection track will move downward until the deflection track is stably aligned with the fixed track.

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

[0015] The effects achieved by the above components are as follows: The cooperation between the rotating plate and the connecting plate can limit the position of the clamping ring, preventing the situation where the clamping ring rotates with the clamping plate and causes damage to the first electric push rod.

[0016] Preferably, a round tube is fixedly assembled at the output end of the second electric push rod, a slider is slidably connected to the inner wall of the round tube, a limiting plate is fixedly assembled at one end of the slider, the limiting plate slidably penetrates the deflection track, and a limiting groove adapted to the limiting plate is formed on the surface of the fixed track.

[0017] The effects achieved by the above components are as follows: The movement of the output end of the second electric push rod will drive the round tube to move, the movement of the round tube will drive the slider to move, and the movement of the slider will drive the limiting plate to move. When the limiting plate is inserted into the inner wall of the limiting groove, the cooperation between the limiting groove and the limiting plate can limit the position of the deflection track.

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

[0019] The effects achieved by the above components are as follows: After the positioning groove and the positioning block are engaged, it can prevent the limiting plate from sliding downward continuously.

[0020] Preferably, a first spring is fixedly assembled on the inner wall of the circular tube, and one end of the first spring is fixedly connected to the slider.

[0021] The effects achieved by the above components are as follows: When the limiting plate is aligned with the limiting groove, the first spring will immediately extend, and the slider will slide by means of the elastic force of the first spring. The sliding of the slider will cause the limiting plate to automatically insert into the inner wall of the limiting groove.

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

[0023] The effects achieved by the above components are as follows: After the inclined surface of the limiting plate contacts the fixed track, the fixed track will squeeze the inclined surface of the limiting plate, and the limiting plate will automatically slide along the diversion track due to the extrusion, thus facilitating the operation.

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

[0025] The effects achieved by the above components are as follows: After the roller contacts the stop rod, the roller will squeeze the stop rod, and the stop rod will slide upward along the diversion track. The sliding of the stop rod will drive the pull plate to slide. At this time, the second spring will pull the pull plate by means of the elastic force, thereby increasing the resistance of the stop rod to the roller.

[0026] Preferably, a damping plate is fixedly assembled on the upper surface of the diversion track, and the damping plate slidably penetrates the pull plate.

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

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

[0029] The effects achieved by the above components are as follows: The movement of the strip-shaped plate will drive the extension rod to move. The extension rod will first abut against the surface of the driven gear. As the first electric push rod continues to extend, the pull plates at both ends of the diversion track will be blocked by the strip-shaped plate. At this time, the lower end of the stop rod will be lower than the central axis of the roller at a high position. Therefore, when subsequent track-changing operations are performed, the stop rods at both ends of the diversion track can prevent the roller from slipping off the surface of the diversion track, resulting in the situation of the transport vehicle falling.

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

[0031] 1. In the present invention, by providing a track-changing structure, during the use of the transport vehicle, the track-changing operation is carried out by first lifting the steering track and then rotating it for alignment. This can ensure that the fixed track and the steering track are in contact 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, and thus facilitating track changing.

[0032] 2. In the present invention, by providing a limiting structure, after the limiting plate is inserted into the inner wall of the limiting groove, the cooperation between the limiting groove and the limiting plate can limit the position of the steering track, preventing the situation where the steering track is misaligned with the fixed track due to the vibration generated during the driving of the transport vehicle, and thus ensuring that the steering track is stably aligned with the fixed track.

[0033] 3. In the present invention, by providing a deceleration structure, when the transport vehicle needs to change tracks, the second spring can use its elastic force to increase the resistance of the blocking rod to the roller. By delaying the movement of the roller, the transport vehicle can be decelerated to stop quickly, facilitating the subsequent rapid track-changing operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0045] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0046] Such as Figures 1-9As shown in the figure, the present invention provides an orbital transportation device facilitating track change, which includes a suspension frame 1, a steering track 4 and a sliding frame 6. A plurality of fixed tracks 2 are fixedly assembled on the lower surface of the suspension frame 1. The fixed tracks 2 abut against the steering track 4. A first rack 3 is fixedly assembled on the lower surface of the fixed tracks 2. A second rack 5 is fixedly assembled on the lower surface of the steering track 4. A transport vehicle 7 is fixedly connected to the lower end of the sliding frame 6. A roller 8 is rotatably connected to the upper end of the sliding frame 6. The outer circumferential surface of the roller 8 abuts against the surface of the steering track 4. A transmission gear 9 meshing with the second rack 5 is rotatably connected in the sliding frame 6. The size of the first rack 3 is adapted to the size of the transmission gear 9. A driving motor 10 is fixedly assembled on the side wall of the sliding frame 6. The output end of the driving motor 10 is fixedly connected to the transmission gear 9. It further includes: a track-changing structure arranged on the lower surface of the suspension frame 1 for driving the steering track 4 to change tracks, the track-changing structure including a bracket 11 fixedly installed on the lower surface of the suspension frame 1, a driven gear 14 for adjusting the angle of the steering track 4 and a driving gear 16, a snap ring 18 and a clamping plate 19 for adjusting the height of the steering track 4; a limiting structure arranged on the inner wall of the steering track 4 for stably aligning the steering track 4 with the fixed track 2, the limiting structure including a second electric push rod 22 fixedly installed on the inner wall of the steering track 4, a limiting plate 25 and a limiting groove 26 for limiting the position of the steering track 4; a decelerating structure arranged on the surface of the steering track 4 for decelerating the transport vehicle 7, the decelerating structure including a plurality of blocking rods 30 slidably penetrating through the steering track 4, and a second spring 32 for increasing the resistance of the blocking rods 30 to the roller 8.

[0047] A rotating ring 12 is rotatably connected in the bracket 11. A transmission rod 13 vertically slides through the rotating ring 12. The driven gear 14 is fixedly assembled at the lower end of the rotating ring 12. A stepping motor 15 is fixedly assembled on the surface of the bracket 11. The output end of the stepping motor 15 is fixedly connected to the driving gear 16. The driven gear 14 meshes with the driving gear 16. A first electric push rod 17 is fixedly assembled on the surface of the bracket 11. The snap ring 18 is fixedly assembled at the output end of the first electric push rod 17. The clamping plate 19 is fixedly assembled at the upper end of the transmission rod 13. The clamping plate 19 is rotatably installed on the inner wall of the snap ring 18. Controlling the extension of the output end of the first electric push rod 17, the snap ring 18 will drive the clamping plate 19 to move upward. The movement of the clamping plate 19 will drive the transmission rod 13 to move. The movement of the transmission rod 13 will drive the steering track 4, making the steering track 4 higher than the fixed track 2. Then, the stepping motor 15 is started. The rotation of the output end of the stepping motor 15 will drive the driving gear 16 to rotate. The rotation of the driving gear 16 will drive the driven gear 14 to rotate. The rotation of the rotating ring 12 following the driven gear 14 will drive the transmission rod 13 to rotate. The transmission rod 13 will drive the steering track 4 to rotate, thereby adjusting the orientation of the steering track 4. When the steering track 4 is aligned with the appropriate track, the stepping motor 15 is turned off. Controlling the contraction of the output end of the first electric push rod 17, at this time, the steering track 4 will move downward until the steering track 4 is stably aligned with the fixed track 2.

[0048] The outer circumferential surface of the snap ring 18 is rotatably connected with a rotating plate 20, the surface of the support 11 is rotatably connected with a connecting plate 21, the connecting plate 21 is rotatably connected with the rotating plate 20, and the cooperation between the rotating plate 20 and the connecting plate 21 can limit the position of the snap ring 18, preventing the situation that the snap ring 18 follows the rotation of the clamping plate 19 and causes damage to the first electric push rod 17.

[0049] The output end of the second electric push rod 22 is fixedly assembled with a circular tube 23, the inner wall of the circular tube 23 is slidably connected with a slider 24, one end of the slider 24 is fixedly assembled with a limiting plate 25, the limiting plate 25 slidably penetrates through the deflecting track 4, and a limiting groove 26 adapted to the limiting plate 25 is formed on the surface of the fixed track 2. The movement of the output end of the second electric push rod 22 will drive the circular tube 23 to move, the movement of the circular tube 23 will drive the slider 24 to move, the movement of the slider 24 will drive the limiting plate 25 to move, and when the limiting plate 25 is inserted into the inner wall of the limiting groove 26, the cooperation between the limiting groove 26 and the limiting plate 25 can limit the position of the deflecting 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 assembled on the inner wall of the limiting groove 26. After the positioning groove 27 and the positioning block 28 are engaged, the limiting plate 25 can be prevented from continuing to slide downward.

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

[0052] A slope is formed on the surface of the limiting plate 25. After the slope of the limiting plate 25 contacts the fixed track 2, the fixed track 2 will squeeze the slope of the limiting plate 25, and the limiting plate 25 will automatically slide along the deflecting track 4 due to the extrusion, thus facilitating the operation.

[0053] The upper end of the blocking rod 30 is fixedly connected with a pulling plate 31, a second spring 32 is sleeved on the outer circumferential surface of the blocking rod 30, and the two ends of the second spring 32 are respectively fixedly connected with the pulling plate 31 and the deflecting track 4. After the roller 8 contacts the blocking rod 30, the roller 8 will squeeze the blocking rod 30, the blocking rod 30 will slide upward along the deflecting track 4, the sliding of the blocking rod 30 will drive the pulling plate 31 to slide, and at this time, the second spring 32 will pull the pulling plate 31 by the elastic force, thereby increasing the resistance of the blocking rod 30 to the roller 8.

[0054] A damping plate 33 is fixedly assembled on the upper surface of the deflecting track 4, the damping plate 33 slidably penetrates through the pulling plate 31, and the damping plate 33 can damp the pulling plate 31, thereby preventing the situation that the blocking rod 30 reciprocates due to the elastic force of the first spring 29.

[0055] A strip-shaped plate 34 is slidably sleeved on the surface of the transmission rod 13. The strip-shaped plate 34 is located above the pull plate 31. The cross-section of the strip-shaped plate 34 is in an "H" shape. An extension rod 35 is fixedly assembled on the upper surface of the strip-shaped plate 34. The movement of the strip-shaped plate 34 will drive the movement of the extension rod 35. The extension rod 35 will first abut 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 steering track 4 will be blocked by the strip-shaped plate 34. At this time, the lower end of the stop rod 30 will be lower than the central axis of the roller 8 at a high position. Therefore, when subsequent track-changing operations are performed, the stop rods 30 at both ends of the steering track 4 can prevent the roller 8 from slipping off the surface of the steering track 4, resulting in the situation where the transport vehicle 7 falls.

[0056] The overall working principle is that when using the transport vehicle 7, the driving motor 10 is turned on. The rotation of the output end of the driving motor 10 will drive the rotation of the transmission gear 9. The transmission gear 9 will move along the surface of the first rack 3, thereby driving the sliding frame 6 to move. The sliding frame 6 will drive the transport vehicle 7 to move. When it is necessary to change the track of the transport vehicle 7, the driving motor 10 is controlled to move the sliding frame 6 to the steering track 4. During this process, since the steering track 4 can abut 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 driving gear can normally move over to the second rack 5. Then the roller 8 will contact the stop rod 30. The roller 8 will squeeze the stop rod 30. The stop rod 30 will slide upward along the inside of the steering track 4. The sliding of the stop rod 30 will drive the sliding of the pull plate 31. At this time, the second spring 32 will pull the pull plate 31 by means of elastic force, thereby increasing the resistance of the stop rod 30 to the roller 8. By delaying the movement of the roller 8, the transport vehicle 7 can be decelerated, so that the transport vehicle 7 can stop quickly, facilitating subsequent rapid track-changing operations. During this process, the pull plate 31 will slide along the surface of the damping plate 33. The damping plate 33 can damp the pull plate 31, thereby preventing the stop rod 30 from bouncing back and forth due to the elastic force of the first spring 29.

[0057] After the transport vehicle 7 stops, control the output end of the second electric push rod 22 to contract. The second electric push rod 22 will drive the round tube 23 to move. When the slider 24 moves with the round tube 23, the limit plate 25 will slide out from the inner wall of the limit groove 26. Then, control the output end of the first electric push rod 17 to extend. The snap ring 18 will drive the clamping plate 19 to move upward. The movement of the clamping plate 19 will drive the transmission rod 13 to move. The movement of the transmission rod 13 will drive the direction-changing track 4, making the direction-changing track 4 higher than the fixed track 2. During this process, the strip plate 34 will move towards 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 abut 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 direction-changing track 4 will be blocked by the strip plate 34. At this time, the lower end of the stop rod 30 will be lower than the central axis of the roller 8 located at a high position. Therefore, when subsequent track-changing operations are carried out, the stop rods 30 at both ends of the direction-changing track 4 can prevent the roller 8 from slipping off the surface of the direction-changing track 4, resulting in the situation where the transport vehicle 7 drops. Then, start the stepping motor 15 and control the output end of the second electric push rod 22 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. The rotation of the driving gear 16 will drive the driven gear 14 to rotate. The rotating ring 12 will drive the transmission rod 13 to rotate as it follows the driven gear 14. The transmission rod 13 will drive the direction-changing track 4 to rotate, thereby adjusting the orientation of the direction-changing track 4. During this process, the rotating plate 20 and the connecting plate 21 cooperate to limit the position of the snap ring 18, preventing the snap ring 18 from rotating with the clamping plate 19 and causing damage to the first electric push rod 17. When the direction-changing track 4 is aligned with the appropriate track, turn off the stepping motor 15 and control the output end of the first electric push rod 17 to contract. At this time, the direction-changing track 4 will move downward. During this process, the direction-changing track 4 will drive the limit plate 25 to move. 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 inside of the direction-changing track 4 due to the extrusion. The sliding of the limit plate 25 will drive the slider 24 to slide along the inner wall of the round tube 23. 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. The slider 24 will slide by means 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. The cooperation between the limit groove 26 and the limit plate 25 can limit the position of the direction-changing track 4. At the same time, the positioning groove 27 will engage with the positioning block 28 to prevent the limit plate 25 from continuing to slide downward, avoiding the situation where the direction-changing track 4 is misaligned with the fixed track 2 due to the vibration generated when the transport vehicle 7 is traveling, and making the direction-changing track 4 stably aligned with the fixed track 2. After that, the transport vehicle 7 can be stably moved to other fixed tracks 2 to complete the track-changing operation.
