Description

Technical Field

[0001] The present invention relates to the technical field of orbital docking, and particularly to a station entry structure. Background Art

[0002] There are numerous tracks in a hanging production line. Between different production processes, loop tracks are often set according to corresponding requirements, and the loop tracks are connected by bridging tracks to achieve the transfer and transportation of carriers between loop tracks. When the carrier is being transported, the bridging track is combined with the main track so that the carrier can smoothly run onto the main track. The current station entry structures mostly adopt a driving structure or an elastic driving structure. The station entry structure of the driving structure needs to set up a control terminal and is controlled by electricity, resulting in a high cost; the elastic driving structure uses a recoverable elastic structure as the power source. After long-term use, the elastic restoring force becomes weak and the structural stability is poor.

[0003] Chinese Patent CN209258979U, published on August 16, 2019, discloses an intelligent rail combination device, including a track. The track includes a main track and an access track. Driving devices are separately provided at both the front and rear sections where the main track is connected to the access track, and there are dialing devices that drive the transportation of goods under the drive of the driving devices. Driving devices are also separately provided on the access track, and there are dialing devices that drive the transportation of goods under the drive of the driving devices. Sensors for sensing the passage of goods are provided on both the front section where the main track is connected to the access track and the access track. The sensors are communicatively connected to a console. The purpose of this invention is to provide an intelligent rail combination device that combines goods on different tracks and transports them to a designated main guide rail, with the rail combination process being intelligently controlled to avoid interference and collision of goods. However, a driving device is separately provided on the access track of this rail combination device, and the driving device is controlled by a control terminal to drive the access track to engage with the main track, resulting in a high implementation cost and being unable to meet the current production requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide a station entry structure for the deficiencies of the above-mentioned prior art, which can achieve the transfer and transportation of carriers between loop tracks, and has a simple structure and strong stability, thereby reducing production costs and improving the stability of carrier transportation.

[0005] The present invention provides an in-station structure, which includes a side-hanging track for longitudinally transporting vehicles, and an access track for transporting the laterally transported vehicles onto the side-hanging track; one end of the access track close to the side-hanging track is provided with a swing track, and the swing track closes or disconnects the access track from the side-hanging track; when the vehicle is transported from the starting end of the side-hanging track to the position where the swing track is located, the swing track is pushed to disconnect the access track from the side-hanging track, and when the vehicle is transported on the access track to the swing track, the swing track is pushed to close the access track to the side-hanging track.

[0006] Further, the side-hanging track includes a main track for hanging the vehicle, and a driving device for driving the vehicle on the main track to move. The main track is arranged at the bottom of the side-hanging track, and the driving device is arranged at the top of the side-hanging track.

[0007] Further, the driving device includes a driving chain slidably connected to the top of the side-hanging track, a pushing block arranged on the driving chain, and a limiting component oppositely arranged to the pushing block on the driving chain. The pushing block pushes the vehicle to move on the main track, and the limiting component limits the vehicle pushed by the pushing block.

[0008] Further, the limiting component includes a switch base fixed on the driving chain, and a switch plate rotatably connected to the switch base. A transport passage for the vehicle to pass through is arranged below the switch base. When the switch plate rotates downward on the switch base, the transport passage is closed, and when the switch plate rotates upward on the switch base, the transport passage is opened.

[0009] Further, the side-hanging track further includes main sliding ribs arranged on the main track. A clamping groove is axially arranged on the main track, and buckles for clamping with the clamping groove are arranged on the main sliding ribs.

[0010] Further, the access track includes a guiding track on one side of the main track, and a limiting pressing track arranged above the guiding track. When the vehicle is transported on the guiding track, the limiting pressing track limits the top of the vehicle. One end of the swing track is rotatably connected to one end of the guiding track close to the main track.

[0011] Further, it further includes a connecting cross beam for fixing the guiding track on one side of the main track. The access track further includes a connecting seat fixedly connected to the top of the connecting cross beam. The guiding track is arranged at the bottom of the connecting seat, and the limiting pressing track is arranged in the middle of the connecting seat.

[0012] Further, the guiding rail is provided with auxiliary sliding ribs for limiting the vehicle, the swinging rail is provided with a limiting rib with one end docked with the auxiliary sliding rib and the other end docked with the docking rib, the middle of the main sliding rib is provided with a docking rib docked with the limiting rib, and the docking rib is provided with a docking chute for the vehicle to transition from the swinging rail to the main rail.

[0013] Further, the swinging rail is provided with swinging wing plates that cooperate with the vehicle and are used for the vehicle to push the swinging rail to rotate on the guiding rail, and the docking rib is provided with docking wing plates that cooperate with the vehicle and are used for correcting the running posture of the vehicle when it transitions to the main rail.

[0014] Further, two blocking slopes are symmetrically arranged at one end of the guiding rail close to the main rail, and the bottom of the swinging rail is provided with a limiting block that cooperates with the blocking slope.

[0015] An in-station structure of the present invention has the following beneficial effects:

[0016] (1) The in-station structure realizes the connection or disconnection of the access track and the side-hanging track by the vehicle pushing the swinging rail to engage or disengage with the side-hanging track. Therefore, the laterally transported vehicle can transition to the side-hanging track through the access track without a separate driving device, realizing the variable-track transportation of the vehicle, meeting the requirements of different processes, and further making the structure of the in-station structure simple and stable, reducing production costs, and improving the stability of vehicle transportation;

[0017] (2) When the driving chain of the in-station structure drives the push block to push the vehicle to run on the main rail, the limiting component restricts the vehicle in the accommodation area, enabling the vehicle to always maintain a synchronous effect with the push block during the running process, thus realizing both the transportation of the vehicle and restricting the running of the vehicle on the main rail, and further facilitating the control of the hanging density and running position of the vehicle to meet the requirements of different processes;

[0018] (3) The main rail of the in-station structure is provided with main sliding ribs, the guiding rail is provided with auxiliary sliding ribs, and the swinging rail is provided with limiting ribs. The main sliding ribs, auxiliary sliding ribs, and limiting ribs are used to limit the vehicles transported on the main rail, guiding rail, and swinging rail respectively, thereby preventing the rollers of the vehicle from running off track or falling when rolling on the main rail, guiding rail, and swinging rail, and improving the stability of vehicle transportation;

[0019] (4) The main sliding rib of the in-station structure is composed of multiple U-shaped plastic sliding ribs spliced together. When part of the main sliding rib is worn or damaged, the worn or damaged part of the main sliding rib can be replaced, thus saving production materials;

[0020] (5) The U-shaped plastic sliding rib of this in-station structure has a certain elastic deformation ability, and a buckle is provided on each side of each U-shaped plastic sliding rib. When an external force is applied to the outside of the U-shaped plastic sliding rib, the U-shaped plastic sliding rib can be deformed to snap the two buckles into the clamping groove, or pull the two buckles out of the clamping groove, thereby further facilitating the maintenance and replacement of the main sliding rib, and improving the convenience of track maintenance;

[0021] (6) The access track of this in-station structure further includes a limiting rail, which extends from above the access track to above the swing track. When the vehicle is transported from the guiding track to the swing track, the limiting rail limits the rollers above the rollers to prevent the rollers from derailing, so that the vehicle is transported more smoothly on the guiding track and the swing track, and further improves the stability of vehicle transportation;

[0022] (7) A limiting block is provided at the bottom of the swing track of this in-station structure, and two blocking slopes are symmetrically provided on the guiding track. The two blocking slopes limit the limiting block on the outside or inside of the arc-shaped curved track respectively to prevent the swing track from rotating in the reverse direction, resulting in the disconnection between the swing track and the conveying platform and affecting the transportation of the vehicle.

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] An inbound structure according to an embodiment of the present invention includes a side-hanging track 1 for longitudinally transporting the vehicle 4, and an access track 2 for transporting the transversely transported vehicle 4 onto the side-hanging track 1; a swing track 23 is provided at one end of the access track 2 close to the side-hanging track 1, and the swing track 23 closes or disconnects the access track 2 from the side-hanging track 1; when the vehicle 4 is transported from the starting end of the side-hanging track 1 to the position where the swing track 23 is located, the swing track 23 is pushed to disconnect the access track 2 from the side-hanging track 1, and when the vehicle 4 is transported on the access track 2 to the swing track 23, the swing track 23 is pushed to close the access track 2 to the side-hanging track 1. For specific effects, see Figure 1 .

[0035] In this application, when the vehicle 4 is mounted on the side-hanging track 1, the side-hanging track 1 is used to longitudinally transport the vehicle 4, and for the transversely transported vehicle 4, it is transported to the side-hanging track 1 through the access track 2. A swing track 23 is provided at one end of the access track 2 close to the side-hanging track 1. When the vehicle 4 only needs to be longitudinally transported, the vehicle 4 is mounted at the starting end of the side-hanging track 1, and the side-hanging track 1 longitudinally transports the vehicle 4; when the vehicle 4 is longitudinally transported on the side-hanging track 1 to the position where the swing track 23 is docked with the side-hanging track 1, the vehicle 4 pushes the swing track 23 to disconnect from the side-hanging track 1, so as to realize the disconnection of the access track 2 from the side-hanging track 1, enabling the vehicle 4 to continue to longitudinally transport towards the end of the side-hanging track 1 on the side-hanging track 1.

[0036] When the vehicle 4 needs to change from lateral transportation to longitudinal transportation, the vehicle 4 first moves laterally onto the access track 2. When the vehicle 4 is transported on the access track 2 to one end close to the side-hanging track 1, the vehicle 4 pushes the swing track 23 to engage with the side-hanging track 1, thereby realizing the merging of the access track 2 and the side-hanging track 1. Under the guidance of the swing track 23, the vehicle 4 enters the side-hanging track 1 through the access track 2. The vehicle 4 that enters the side-hanging track 1 continues to be longitudinally transported on the side-hanging track 1 towards the end of the side-hanging track 1, thereby realizing the transfer transportation of the vehicle 4 between the interval tracks.

[0037] In this application, since it is the vehicle 4 that pushes the swing track 23 to engage or disconnect from the side-hanging track 1 to realize the merging or disconnection of the access track 2 and the side-hanging track 1, the laterally transporting vehicle 4 can transition to the side-hanging track 1 through the access track 2 without a separate driving device 12, realizing the track-changing transportation of the vehicle 4, meeting different process requirements, and further making the structure of this in-station structure simple and stable, reducing production costs, and improving the transportation stability of the vehicle 4.

[0038] In this embodiment, the side-hanging track 1 includes a main track 11 for hanging the vehicle 4, and a driving device 12 for driving the vehicle 4 on the main track 11 to move. The main track 11 is arranged at the bottom of the side-hanging track 1, and the driving device 12 is arranged at the top of the side-hanging track 1. For the specific effect, see Figure 2 The side-hanging track 1 includes a main track 11 and a driving device 12. The main track 11 is arranged at the bottom of the side-hanging track 1, and the driving device 12 is arranged at the top of the side-hanging track 1. When the vehicle 4 is mounted on the main track 11, the driving device 12 drives the vehicle 4 to move longitudinally along the main track 11, realizing the longitudinal transportation of the vehicle 4.

[0039] It can be foreseen that the movement of the vehicle 4 on the access track 2 can be driven by also arranging a driving device above the guiding track 21, or the guiding track 21 can be set to be inclined obliquely downward towards the main track 11, so that the vehicle 4 on the guiding track 21 moves towards the main track 11 under the action of its own gravity and the gravity of the hung fabric. Therefore, in this application, it is the driving force of the vehicle 4 during transportation on the main track 11 and the guiding track 21 that enables the vehicle 4 to push the swing track 23 to engage or disconnect from the main track 11, so that the laterally transporting vehicle 4 can transition to the main track 11 through the guiding track 21 and the swing track 23 without a separate driving device 12, realizing the track-changing transportation of the vehicle 4, meeting different process requirements, and further making the structure of this in-station structure simple and stable, reducing production costs, and improving the transportation stability of the vehicle 4.

[0040] In this embodiment, the driving device 12 includes a driving chain 121 slidably connected to the top of the side-hanging track 1, a pushing block 122 provided on the driving chain 121, and a limiting component oppositely arranged to the pushing block 122 on the driving chain 121. The pushing block 122 pushes the carrier 4 to move on the main track 11, and the limiting component limits the carrier 4 pushed by the pushing block 122. For the specific effect, see Figure 2 and Figure 3 . The driving device 12 includes a driving chain 121, a pushing block 122, and a limiting component. The driving chain 121 is hung on the top of the side-hanging track 1 and is slidably connected to the side-hanging track 1. The pushing block 122 and the limiting component are oppositely arranged on the driving chain 121 and are separated by a certain distance, forming a receiving area for accommodating the carrier 4 therebetween. It can be foreseen that: a sliding groove is provided at the top of the side-hanging track 1, and the upper end of the driving chain 121 is slidably matched with the sliding groove. Driven by the power mechanism, the driving chain 121 moves in the sliding groove, thereby driving the pushing block 122 and the limiting component located on the driving chain 121 to move synchronously.

[0041] When the pushing block 122 is on one side of the carrier 4 and pushes the carrier 4 located in the receiving area to move on the main track 11, the limiting component is on the other side of the carrier 4 to limit the carrier 4. Therefore, when the driving chain 121 drives the pushing block 122 to push the carrier 4 to run on the main track 11, the limiting component restricts the carrier 4 in the receiving area. When the driving chain 121 starts, the carrier 4 moves synchronously with the driving chain 121. When the driving chain 121 stops running, the carrier 4 stops moving synchronously, thereby not only realizing the transportation of the carrier 4 but also restricting the operation of the carrier 4 on the main track 11, and further facilitating the control of the hanging density and running position of the carrier 4 to meet the requirements of different processes.

[0042] In this application, the roller-side-hanging type carrier 4 is adopted. Therefore, the carrier 4 rolls on the main track 11, the guiding track 21, and the swing track 23 through the rollers 41 of the carrier 4, driving the clothes hanger 42 side-hung on the rollers 41 to move synchronously, thereby realizing the transportation of the fabric hung on the clothes hanger 42. For the specific effect, see Figure 1 and Figure 6It can be foreseen that when the vehicle 4 is transported on the main track 11, the rollers 41 of the vehicle 4 are located in the accommodation area between the push block 122 and the limiting component. The push block 122 pushes the rollers 41 located in the accommodation area to roll on the main track 11, and the limiting component limits the rollers 41 located in the accommodation area. Therefore, the accommodation area enclosed by the push block 122 and the limiting component can be an arc-shaped space with the same shape as the outer shape of the roller 41. On the one hand, it can make the accommodation area better accommodate the roller 41. On the other hand, it is to increase the contact area between the push block 122 and the roller 41 when the push block 122 pushes the roller 41 to roll on the main track 11, so that the driving effect of the push block 122 on the vehicle 4 is better, and the operation of the vehicle 4 on the main track 11 is more stable.

[0043] In order to prevent the accommodation area enclosed by the push block 122 and the limiting component from hindering the rolling of the roller 41, the diameter of the accommodation area should be greater than the diameter of the roller 41. If the diameter of the accommodation area is much larger than the diameter of the roller 41, it will affect the limiting effect of the limiting component on the vehicle 4. Therefore, in this application, it is preferably that the diameter of the accommodation area is greater than the diameter of the roller 41 and less than twice the diameter of the roller 41.

[0044] In this embodiment, the limiting component includes a switch base 123 fixed on the driving chain 121 and a switch plate 124 rotatably connected to the switch base 123. A transport passage for the vehicle 4 to pass through is provided below the switch base 123. When the switch plate 124 rotates downward on the switch base 123, the transport passage is closed. When the switch plate 124 rotates upward on the switch base 123, the transport passage is opened. For the specific effect, see Figure 2 and Figure 3 The limiting component includes a switch base 123 and a switch plate 124. The switch base 123 is fixed at the lower end of the driving chain 121, and the top of the switch plate 124 is rotatably connected to the switch base 123. A transport passage is provided below the switch base 123. Initially, the switch plate 124 extends vertically downward on the switch base 123 to close the transport passage. When the roller 41 abuts against the switch plate 124, the switch plate 124 rotates upward by a certain angle with the rotation connection point with the switch base 123 as the center to open the transport passage, so that the roller 41 can enter the accommodation area through the transport passage.

[0045] After the roller 41 enters the accommodation area, it no longer abuts against the switch plate 124. Under the action of its own gravity, the switch plate 124 rotates downward by a certain angle with the rotation connection point with the switch base 123 as the center, and returns to the state of extending vertically downward on the switch base 123, closing the transport channel. Since the switch plate 124 extends vertically downward on the switch base 123 is the limit of its downward rotation, at this time, the roller 41 located in the accommodation area abuts against the switch plate 124 and cannot make the switch plate 124 rotate. Therefore, when the push block 122 pushes the roller 41 to roll on the main rail 11 at one end of the roller 41, the switch plate 124 limits the roller 41 at the other end of the roller 41, preventing it from moving out of the accommodation area through the transport channel, thus restricting the roller 41 in the accommodation area.

[0046] In this application, an elastic buffer plate 1241 is provided on the switch plate 124. For specific effects, see Figure 4 . After the switch plate 124 rotates upward by a certain angle under the abutment of the roller 41, the elastic buffer plate 1241 abuts against the switch base 123. At this time, the roller 41 can just enter the accommodation area through the transport channel under the switch plate 124. Thus, the elastic buffer plate 1241 not only limits the upward rotation angle of the switch plate 124, but also reduces the collision force between the switch plate 124 and the switch base 123, extending the service life of the limiting component.

[0047] A limiting boss 1242 is also provided on the switch plate 124. For specific effects, see Figure 4 . When the switch plate 124 extends vertically downward on the switch base 123, the limiting boss 1242 abuts against the switch base 123, enabling the switch plate 124 to only rotate upward in the direction of the push block 122 and preventing it from rotating in the reverse direction. Thus, when the roller 41 enters the transport channel from the side of the switch base 123 away from the push block 122, it can push the switch plate 124 to rotate upward in the direction of the push block 122, opening the transport channel and allowing the roller 41 to enter the accommodation area through the transport channel.

[0048] After the roller 41 enters the accommodation area, the switch plate 124 rotates downward under the action of its own gravity until it returns to the state of extending vertically downward on the switch base 123. At this time, the limiting boss 1242 abuts against the switch base 123, preventing the switch plate 124 from rotating in the same direction anymore. Therefore, when the push block 122 pushes the roller 41 to roll in the accommodation area, the switch plate 124 and the switch base 123 limit the roller 41 in the accommodation area, enabling the vehicle 4 to always maintain a synchronous effect with the push block 122 during operation.

[0049] It can be foreseen that when the vehicle 4 only needs to perform vertical transportation, first mount the rollers 41 of the vehicle 4 at the starting end of the main rail 11, and the rollers 41 stop in front of the limit component and the push block 122. Then start the drive chain 121. Driven by the drive chain 121, the limit component and the push block 122 move towards the rollers 41. Since the limit component is on the drive chain 121 and is located on the side close to the rollers 41, when the limit component and the push block 122 reach the position where the rollers 41 are located, the switch plate 121 of the limit component abuts against the rollers 41 stopped on the main rail 11, causing the rollers 41 to push the switch plate 121 to rotate upward in the direction of the push block 122, opening the transportation channel under the switch base 123. The rollers 41 enter the accommodation area through the transportation channel, so that the push block 122 pushes the rollers 41 to roll on the main rail 11, and the limit component restricts the rollers 41 in the accommodation area, realizing the transportation of the vehicle 4 on the main rail 11.

[0050] When the vehicle 4 changes from horizontal transportation to vertical transportation, after the rollers 41 of the vehicle 4 are transported from the swing rail 23 to the main rail 11, due to the lack of driving force, the rollers 41 stop at the connection between the main rail 11 and the swing rail 23. Then start the drive chain 121, so that the limit component and the push block 122 move towards the end of the side-hanging rail 1 under the drive of the drive chain 121 and reach the connection between the main rail 11 and the swing rail 23. The limit component is on the drive chain 121 and is located on the side close to the rollers 41. Thus, under the drive of the drive chain 121, the switch plate 121 of the limit component abuts against the rollers 41 stopped on the main rail 11, causing the rollers 41 to push the switch plate 121 to rotate upward in the direction of the push block 122, opening the transportation channel under the switch base 123. The rollers 41 enter the accommodation area through the transportation channel, so that the push block 122 pushes the rollers 41 to roll on the main rail 11, and the limit component restricts the rollers 41 in the accommodation area, realizing the transportation of the vehicle 4 on the main rail 11.

[0051] In this embodiment, the side-hanging rail 1 further includes a main sliding rib 13 provided on the main rail 11. A clamping groove 111 is axially provided on the main rail 11, and a buckle 141 for clamping with the clamping groove 111 is provided on each of the main sliding ribs 13. For the specific effects, see Figure 2 and Figure 8 . A main sliding rib 13 is provided on the main rail 11. When the vehicle 4 is transported on the main rail 11, the rollers 41 of the vehicle 4 straddle both sides of the main sliding rib 13, so that the main sliding rib 13 positions and guides the rollers 41, preventing the rollers 41 from running off or falling off the main rail 11 when rolling on the main rail 11, which affects the transportation of the vehicle 4.

[0052] Since the main sliding rib 13 will inevitably rub against the roller 41 when limiting the roller 41, after long-term use, the main sliding rib 13 will experience significant wear. Continuing to use it will affect the limiting effect of the main sliding rib 13 on the roller 41. Therefore, when the main sliding rib 13 shows significant wear, the main sliding rib 13 needs to be replaced to ensure the limiting effect of the main sliding rib 13 on the roller 41, and further ensure the smoothness of the carrier 4 during transportation on the main rail 11.

[0053] Therefore, in this application, a clamping groove 111 is axially provided on the main rail 11, and a buckle 141 is provided on the main sliding rib 13. The main sliding rib 13 is fixed on the main rail 11 by clamping the buckle 141 with the clamping groove 111, so that the main sliding rib 13 limits the roller 41 moving on the main rail 11. Therefore, when the main sliding rib 13 shows significant wear and needs to be replaced, the buckle 141 on the main sliding rib 13 is disengaged from the clamping groove 111 on the main rail 11, and the main sliding rib 13 can be removed from the main rail 11 for replacement, thus making the repair and replacement of the main sliding rib 13 convenient and fast, and further improving the convenience of track repair.

[0054] In this application, the main sliding rib 13 is formed by splicing multiple U-shaped plastic sliding ribs. The length of the main rail 11 is much greater than the length of a single U-shaped plastic sliding rib, and the length of the clamping groove 111 axially provided on the main rail 11 is also much greater than the length of a single U-shaped plastic sliding rib. When limiting the carrier 4, multiple U-shaped plastic sliding ribs are axially clamped along the clamping groove 111, and the multiple U-shaped plastic sliding ribs are spliced into a complete main sliding rib 13 to limit the carrier 4. The reason for designing the main sliding rib 13 in this structure is to replace the worn or damaged part of the main sliding rib 13 when part of the main sliding rib 13 is worn or damaged, thus saving production materials.

[0055] At the same time, there are two buckles 141 respectively arranged on both sides of each U-shaped plastic sliding rib. Since the U-shaped plastic sliding rib has a certain elastic deformation ability, by applying a force on the outer side of the U-shaped plastic sliding rib, the distance between the two buckles 141 on the outer side of the U-shaped plastic sliding rib can be reduced, thus facilitating the disengagement of the two buckles 141 from the clamping groove 111 and removing the U-shaped plastic sliding rib from the main rail 11, and further facilitating the replacement of the U-shaped plastic sliding rib. When the force applied on the outer side of the U-shaped plastic sliding rib is released, under the elastic action of the U-shaped plastic sliding rib itself, the distance between the two buckles 141 returns to the original state, thus facilitating the simultaneous clamping of the two buckles 141 on the outer side of the U-shaped plastic sliding rib with the clamping groove 111 to realize the fixation of the U-shaped plastic sliding rib on the main rail 11.

[0056] This is set because the position where wear or damage may occur is in the middle section of the main sliding rib 13. If multiple U-shaped plastic sliding ribs are inserted into the clamping groove 111 in sequence from the end of the clamping groove 111 to form a complete main sliding rib 13, when the guide rail of the U-shaped plastic sliding rib in the middle needs to be replaced, it is also necessary to sequentially extract multiple U-shaped plastic sliding ribs in front of this U-shaped plastic sliding rib from the clamping groove 111. This also makes the repair and replacement of the main sliding rib 13 relatively troublesome and affects production efficiency.

[0057] Therefore, in this application, through the elastic deformation ability of the U-shaped plastic sliding rib itself, an external force is applied to the outside of the U-shaped plastic sliding rib to cause the U-shaped plastic sliding rib to deform and then snap the two buckles 141 into the clamping groove 111, or pull the two buckles 141 out of the clamping groove 111. Therefore, no matter which U-shaped plastic sliding rib wears or is damaged, the U-shaped plastic sliding rib can be directly replaced without moving other U-shaped plastic sliding ribs to make way for the U-shaped plastic sliding rib to be replaced, thus further making the repair and replacement of the main sliding rib 13 convenient and fast and improving the convenience of track maintenance.

[0058] In this embodiment, the access track 2 includes a guiding track 21 on one side of the main track 11 and a limiting pressing track 22 provided above the guiding track 21. When the carrier 4 is transported on the guiding track 21, the limiting pressing track 22 limits the top of the carrier 4. One end of the swing track 23 is rotatably connected to the end of the guiding track 21 close to the main track 11. For specific effects, see Figure 5 . The access track 2 includes a guiding track 21. The guiding track 21 is arranged on one side of the main track 11. One end of the swing track 23 is rotatably connected to the end of the guiding track 21 close to the main track 11. When the carrier 4 pushes the swing track 23 to rotate inward with the rotation connection point with the guiding track 21 as the center of the circle, when the other end of the swing track 23 abuts against the main track 11, the swing track 23 is joined with the main track 11, realizing the rail combination of the guiding track 21 and the main track 11, so that the carrier 4 for horizontal transportation can transition to the main track 11 through the guiding track 21 and the swing track 23; when the carrier 4 pushes the swing track 23 to rotate outward with the rotation connection point with the guiding track 21 as the center of the circle, when the other end of the swing track 23 separates from the main track 11, the swing track 23 is disconnected from the main track 11, realizing the rail disconnection of the guiding track 21 and the main track 11, so that the carrier 4 for longitudinal transportation on the main track 11 cannot transition to the guiding track 21 through the swing track 23.

[0059] In this application, a swing wing plate 232 is arranged on the swing track 23. For specific effects, see Figure 7. When the vehicle 4 is transported from the guiding rail 21 to the swinging rail 23, the rollers 41 of the vehicle 4 act on the swinging wing plate 232, thereby pushing the swinging rail 23 to rotate inward by a certain angle with the rotation connection point with the guiding rail 21 as the center until the swinging rail 23 engages with the main rail 11. At this time, the end of the swinging rail 23 far from the rotation connection with the guiding rail 21 abuts against the side surface of the main rail 11. Therefore, the swinging rail 23 cannot continue to rotate in the same direction under the push of the vehicle 4, so that the vehicle 4 on the guiding rail 21 can be transported from the swinging rail 23 to the main rail 11.

[0060] The access rail 2 further includes a limiting pressing rail 22. When the rollers 41 of the vehicle 4 roll on the guiding rail 21, the limiting pressing rail 22 is above the rollers 41 of the vehicle 4 to limit the rollers 41, so that the vehicle 4 is transported more smoothly on the main guiding rail. Since the vehicle 4 is transported from the guiding rail 21 to the swinging rail 23, the rollers 41 need to act on the swinging wing plate 232 to push the swinging rail 23 to engage with the main rail 11. During this process, the swinging wing plate 232 will also generate a reaction force on the rollers 41, which may cause the rollers 41 to disengage from the swinging rail 23, resulting in the risk of derailment of the vehicle 4. Therefore, in this application, it is preferably that the limiting pressing rail 22 extends from above the guiding rail 21 to above the swinging rail 23. When the vehicle 4 is transported from the guiding rail 21 to the swinging rail 23, the limiting pressing rail 22 limits the rollers 41 above the rollers 41 to prevent the rollers 41 from derailing.

[0061] In this embodiment, it further includes a connecting cross beam 3 for fixing the guiding rail 21 on one side of the main rail 11. The access rail 2 further includes a connecting seat 24 whose top is fixedly connected to the connecting cross beam 3. The guiding rail 21 is arranged at the bottom of the connecting seat 24, and the limiting pressing rail 22 is arranged in the middle of the connecting seat 24. For the specific effect, see Figure 1 and Figure 5 . In this application, a connecting cross beam 3 is also provided. The connecting cross beam 3 is horizontally fixed on the top of the side-hanging rail 1. The access rail 2 further includes a connecting seat 24. The top of the connecting seat 24 is fixed on the connecting cross beam 3. The guiding rail 21 is arranged at the bottom of the connecting seat 24, and the limiting pressing rail 22 is arranged in the middle of the connecting seat 24. Thus, through the connecting seat 24 and the connecting cross beam 3, the guiding rail 21 is fixed on one side of the main rail 11, and the limiting pressing rail 22 is fixed above the guiding rail 21.

[0062] In this embodiment, the guiding rail 21 is provided with auxiliary sliding ribs 211 for limiting the vehicle 4. The middle part of the main sliding rib 13 is provided with a docking rib 14. The swinging rail 23 is provided with a limiting rib 231 whose one end is docked with the auxiliary sliding rib 211 and the other end is docked with the docking rib 14. The docking rib 14 is provided with a docking chute 142 for the vehicle 4 to transition from the swinging rail 23 to the main rail 11. For the specific effect, see Figure 5 and Figure 8。The secondary sliding rib 211 is provided on the guiding rail 21. When the carrier 4 is transported on the guiding rail 21, the rollers 41 of the carrier 4 straddle both sides of the secondary sliding rib 211, so that the secondary sliding rib 211 positions and guides the rollers 41, preventing the rollers 41 from running off track or falling off the guiding rail 21 when rolling on the guiding rail 21, which affects the transportation of the carrier 4. The limiting rib 231 is also provided on the swinging rail 23. When the carrier 4 is transported on the swinging rail 23, the rollers 41 straddle both sides of the limiting rib 231, and the limiting rib 231 positions the rollers 41 to prevent the rollers 41 from falling off the swinging rail 23.

[0063] As mentioned above, the main sliding rib 13 is formed by splicing a plurality of U-shaped plastic sliding ribs and the docking rib 14 in the middle of the plurality of U-shaped plastic sliding ribs. The two ends of the docking rib 14 are respectively spliced with the front and rear U-shaped plastic sliding ribs. When the swinging rail 23 is joined to the main rail 11, one end of the limiting rib 231 on the sliding rail is docked with the secondary sliding rib 211 on the guiding rail 21, and the other end is docked with the docking rib 14 on the main rail 11. Thus, when the rollers 41 of the carrier 4 are transported from the guiding rail 21 and the swinging rail 23 to the main rail 11, they are successively positioned by the secondary sliding rib 211, the limiting rib 231, and the docking rib 14. When the carrier 4 is longitudinally transported from the initial end of the main rail 11 to the position where the swinging rail 23 is located, the U-shaped plastic sliding rib at the front end of the docking rib 14 positions the rollers 41. When the carrier 4 continues to be longitudinally transported from the position where the swinging rail 23 is located towards the end of the main rail 11, the U-shaped plastic sliding rib at the rear end of the docking rib 14 positions the rollers 41.

[0064] It can be foreseen that: the docking rib 14 is also made of plastic material and has a certain elastic deformation ability. A buckle 141 is provided on each of the two outer sides of the docking rib 14. By applying a force on the two outer sides of the docking rib 14, the distance between the buckles 141 on the two outer sides of the docking rib 14 is shortened. After the two buckles 141 are simultaneously clamped with the clamping groove 111, the force applied on the two outer sides of the docking rib 14 is released. Under the elastic action of the docking rib 14 itself, the distance between the two buckles 141 returns to the original state, thus facilitating the simultaneous clamping of the two buckles 141 on the outer side of the docking rib 14 with the clamping groove 111 and realizing the fixation of the docking rib 14 on the main rail 11. When the docking rib 14 is worn or damaged, a force is applied on the two outer sides of the docking rib 14 to shorten the distance between the two buckles 141 on the outer side of the docking rib 14, thus facilitating the disengagement of the two buckles 141 from the clamping groove 111 and removing the docking rib 14 from the main rail 11, and further facilitating the replacement of the docking rib 14.

[0065] Since the secondary sliding rib 211, the limiting rib 231, the docking rib 14, and the U-shaped plastic sliding rib limit the vehicle 4 by the roller 41 straddling both sides of the secondary sliding rib 211, the limiting rib 231, the docking rib 14, and the U-shaped plastic sliding rib, a docking chute 142 is provided on the docking rib 14, so that the roller 41 straddling both sides of the limiting rib 231 on the swing rail 23 can transition to both sides of the docking rib 14 through the docking chute 142, thereby realizing the transition of the vehicle 4 from the swing rail 23 to the main rail 11. It can be foreseen that: in order to make the transition of the vehicle 4 from the access rail 2 to the side-hanging rail 1 smoother, the guiding rail 21 is an arc-shaped rail, and the swing rail 23 arc-connects the guiding rail 21 and the main rail 11. Therefore, the docking chute 142 provided on the docking rib 14 is also arc-shaped. When the swing rail 23 is joined with the main rail 11, the guiding rail 21, the swing rail 23, and the docking chute 142 have the same curvature, so that the transition of the vehicle 4 from the swing rail 23 to the main rail 11 is smoother.

[0066] In the present application, a docking wing plate 143 is further provided on the docking rib 14. For specific effects, see Figure 8 . When the vehicle 4 is transported from the swing rail 23 to the main rail 11, through the cooperation of the docking wing plate 143 and the roller 41 of the vehicle 4, the docking wing plate 143 further limits and guides the roller 41, thereby correcting the running attitude of the vehicle 4 after transitioning to the main rail 11 and improving the transportation stability of the vehicle 4. In the present application, the roller 41 of the vehicle 4 is composed of two wheels on both sides and a roller shaft connecting the centers of the two wheels. It can be foreseen that: a cylindrical boss with a diameter smaller than that of the wheel is provided on the inner sides of the two wheels. When the vehicle 4 is transported from the guiding rail 21 to the swing rail 23, the cylindrical bosses on the inner sides of the two wheels act on the swing wing plate 232, pushing the swing rail 23 to rotate inward by a certain angle, so that the swing rail 23 is joined with the main rail 11; when the vehicle 4 is transported on the main rail 11, the docking rib 14 limits the inner sides of the two wheels, and the docking wing plate 143 further limits the circular bosses on the inner sides of the two wheels, thereby improving the transportation stability of the vehicle 4.

[0067] In this embodiment, two blocking slopes 212 are symmetrically provided at one end of the guiding rail 21 close to the main rail 11, and a limiting block 233 cooperating with the blocking slopes 212 is provided at the bottom of the swing rail 23. For specific effects, see Figure 5 and Figure 7A limit block 233 is provided at the bottom of the swing rail 23, and two blocking slopes 212 are symmetrically provided on the guide rail 21. When the carrier 4 is transported from the guide rail 21 to the swing rail 23, the roller 41 of the carrier 4 acts on the swing wing plate 232 to push the swing rail 23 to rotate inwardly by a certain angle. At this time, the limit block 233 at the bottom of the swing rail 23 passes over the highest point of the blocking slope 212 on the outside of the guide rail 21 until the swing rail 23 is engaged with the main rail 11. The blocking slope 212 on the inside of the guide rail 21 limits the limit block 233 at the bottom of the swing rail 23 to prevent the swing rail 23 from rotating in the opposite direction during the transportation of the carrier 4 from the swing rail 23 to the main rail 11, causing the swing rail 23 to be disconnected from the main rail 11, thereby affecting the transportation of the carrier 4.

[0068] When the carrier 4 is longitudinally transported from the starting end of the main rail 11 to the position where the swing rail 23 is connected to the main rail 11, the roller 41 of the carrier 4 pushes the swing rail 23 to rotate outward by a certain angle. At this time, the limit block 233 at the bottom of the swing rail 23 passes the highest point of the blocking slope 212 on the inner side of the guide rail 21, so that the blocking slope 212 on the outer side of the guide rail 21 limits the swing rail 23, preventing the swing rail 23 from rotating in the opposite direction, thereby hindering the carrier 4 from continuing to be longitudinally transported on the main rail 11.

[0069] The contents described above may be implemented individually or in combination in various ways, and these variations are all within the protection scope of the present invention.
