Description

Technical Field

[0001] This invention relates to the field of vehicle transportation technology, and in particular to a combined transportation track. Background Technology

[0002] Existing production lines mostly use lightweight transport tracks, which can drive vehicles with relatively small driving forces and structural load-bearing capacity. However, lightweight transport systems are unsuitable for heavy-duty overhead conveyor lines due to significant differences in both structural strength and driving force requirements. Using rigid bird hooks to drive heavy vehicles on the transport tracks allows for the transport of heavy vehicles along the tracks and control of their speed. However, on production lines, the junctions between transverse and longitudinal tracks are typically formed by curved tracks. The combination of rigid bird hooks and curved tracks is extremely poor, failing to effectively drive heavy vehicles on the track.

[0003] Chinese patent CN210824123U, published on 2020-06-23, discloses a bird hook and a conveyor line containing the bird hook. The purpose of this utility model is achieved as follows: A bird hook has a limiting groove formed on it for propelling a carrier forward. An upward abutment and a downward abutment are formed on both sides of the limiting groove. A center line A is formed on the limiting groove. The lower ends of both the upward and downward abutments are inclined towards the center line A. Specifically, the limiting groove is designed as a trapezoidal shape (wider at the top and narrower at the bottom) or an arc shape with one end, essentially a downward-narrowing shape. This design ensures that the carrier is firmly locked within the limiting groove during both upward and downward movement. This design is simple and effective, and highly suitable for practical factory applications. The bird hook conveyor line enables the transport of heavy vehicles on straight tracks. However, at the junction of the transverse and longitudinal tracks, the rigid bird hook and the curved docking track have a very poor combination effect, which cannot effectively achieve on-track driving of heavy vehicles. As a result, the transport effect of vehicles on the curved docking track is poor and cannot meet the current production needs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a combined transport track that can both transport heavy vehicles on the transport track and ensure the driving effect of heavy vehicles on the arc docking track, while also controlling the transport speed and transport spacing of heavy vehicles on the transport track.

[0005] This invention proposes a combined transport track, including a transverse track for transporting a vehicle, a longitudinal track for transporting the vehicle, an arc-shaped docking track for connecting the transverse and longitudinal tracks, a birdhook drive device located on one side of the transverse and longitudinal tracks for mounting or releasing the vehicle, and a brush drive device located on one side of the arc-shaped docking track; the birdhook drive device drives the vehicle to transport on the transverse and longitudinal tracks, and the brush drive device drives the vehicle to transport on the arc-shaped docking track.

The brush circulation track is an arc-shaped track with the same shape as the arc-shaped docking track.

[0007] Furthermore, the birdhook drive device includes a birdhook circulation track disposed on one side of the transverse track and the longitudinal track, a second driving wheel disposed at the bottom of one end of the birdhook circulation track, a second driven wheel disposed at the bottom of the other end of the birdhook circulation track, a second chain with its two ends respectively sleeved on the second driving wheel and the second driven wheel, a birdhook assembly disposed on the second chain, and a second drive motor disposed at the top of the birdhook circulation track. The birdhook assembly is used to mount or release the vehicle, and the second drive motor is used to drive the second driving wheel to rotate.

[0008] Furthermore, the bird hook assembly includes a bird hook seat fixed to the second chain, a bird hook rotatably connected at one end to the bird hook seat, and a torsion spring abutting at one end to the bird hook and at the other end to the bird hook seat.

[0009] Furthermore, a mounting post is provided on one side of the vehicle, and a mounting groove for engaging with the mounting post is provided at the end of the bird hook that is rotatably connected to the bird hook seat.

[0010] Furthermore, the bird hook drive device also includes a carrier release plate located at the bottom of one end of the bird hook circulation track for lifting the bird hook, and a crash plate located at the bottom of the other end of the bird hook circulation track for lifting the bird hook. Both the carrier release plate and the crash plate are provided with an inclined portion for lifting the bird hook away from the end rotatably connected to the bird hook seat when the bird hook passes through.

[0011] Furthermore, the bird hook drive device also includes a chain tensioning assembly located at the top of the other end of the bird hook circulation track for tensioning the second chain.

[0012] Furthermore, the chain tensioning assembly includes a mounting base fixed to the top of the other end of the bird hook circulation track, a fixed gear fixed to the bottom of the mounting base, and a movable gear that can move laterally at the bottom of the mounting base. The second driven wheel is located at the bottom of the mounting base and is longitudinally aligned with the second driving wheel. One end of the second chain is sleeved on the second driving wheel, and the other end is simultaneously sleeved on the fixed gear, the movable gear, and the second driven wheel.

[0013] Furthermore, it also includes a diversion track with one end connected to one end of the transverse track and the other end connected to the arc-shaped docking track or another transverse track, as well as a reversing device for adjusting the diversion track's connection to the arc-shaped docking track and the other transverse track respectively.

[0014] Furthermore, the diversion track is a flexible track, and the reversing device includes a fixed base disposed on one of the transverse tracks, another transverse track, and an arc-shaped docking track, with one end rotatably connected to the fixed base; a rocker arm disposed on the fixed base for driving the rocker arm to rotate a certain arc; and a connecting column for connecting the diversion track and the rocker arm. The fixed base is provided with an arc-shaped hole, and the extended end of the cylinder is fixedly connected to the end of the rocker arm away from the end rotatably connected to the fixed base. One end of the connecting column is fixedly connected to the end of the diversion track away from the end of the transverse track, and the other end passes through the arc-shaped hole and is fixedly connected to the end of the rocker arm away from the end rotatably connected to the fixed base.

[0015] The combined transport track of the present invention has the following gain effect:

[0016] (1) When the vehicle of this transport track is transported on the transverse track or the longitudinal track, the bird hook drive device pulls the vehicle on the transverse track and the longitudinal track, thereby providing a large driving force to the vehicle and realizing the transport of heavy vehicles on the transport track;

[0017] (2) On the arc docking track of this transport track, the vehicle is driven by a brush drive device. Since the brush drive device can better fit the arc docking track, it can ensure the driving effect of the heavy vehicle on the arc docking track, thereby ensuring the transport efficiency of the vehicle on the transport track.

[0018] (3) The first chain of this transport track is a circular track with a slight curvature, that is, the movement track of the brush is a circular track with a slight curvature, so that when the brush moves on the brush circulation track, it fits well with the arc docking track, thereby ensuring the driving effect of the heavy vehicle on the arc docking track.

[0019] (4) The second chain of this transport track is in the shape of a circular track, that is, the bird hook assembly moves in a circular motion along the circular track on the bird hook circular track. Therefore, the bird hook assembly can be reused, thereby reducing production costs and saving resources. Multiple bird hook assemblies can run on the bird hook circular track at the same time, driving multiple vehicles to transport on the transverse or longitudinal track respectively, thereby improving the working efficiency of this device.

[0020] (5) The vehicle on one side of the transport track is provided with a hook post, and the end of the bird hook away from the rotatable connection with the bird hook is provided with a hook groove. The bird hook drive device also includes a vehicle release plate and a crash plate. Both the vehicle release plate and the crash plate are provided with inclined parts, so that when the bird hook passes through the vehicle release plate and the crash plate, the end of the bird hook away from the rotatable connection with the bird hook seat is lifted under the abutment of the inclined parts, thereby realizing the release of the vehicle and preventing the bird hook from interfering with the vehicle.

[0021] (6) The bird hook drive device of this transport track also includes a chain tensioning assembly. The chain tensioning assembly is located at the top of the other end of the bird hook circulation track and is used to adjust the tension of the second chain, thereby ensuring the transmission efficiency and service life of the second chain.

[0022] (7) The diversion track and reversing device of this transport track. The diversion track is a flexible track. Therefore, the direction of the diversion track can be adjusted by the reversing device and fixed to it, so that the diversion track can be connected to another transverse track or arc docking track to realize the transport of the vehicle in multiple directions and meet the needs of actual production.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] An embodiment of the present invention provides a combined transport track, comprising a transverse track 1 for transporting a vehicle 8, a longitudinal track 2 for transporting the vehicle 8, an arc-shaped docking track 3 connecting the transverse track 1 and the longitudinal track 2, a birdhook drive device 4 located on one side of the transverse track 1 and the longitudinal track 2 for mounting or releasing the vehicle 8, and a brush drive device 5 located on one side of the arc-shaped docking track 3; the birdhook drive device 4 drives the vehicle 8 to transport on the transverse track 1 and the longitudinal track 2, and the brush drive device 5 drives the vehicle 8 to transport on the arc-shaped docking track 3. See [details omitted for brevity]. Figure 1 .

[0034] In this application, the carrier 8 is transported on a transverse track 1 and a longitudinal track 2. A birdhook drive device 4 is provided on one side of both the transverse track 1 and the longitudinal track 2. An arc-shaped docking track 3 connects the transverse track 1 and the longitudinal track 2. When the birdhook drive device 4 on one side of the transverse track 1 attaches the carrier 8 to the transverse track 1, it can pull the carrier 8 to transport it on the transverse track 1. When the birdhook drive device 4 pulls the carrier 8 to the end where the transverse track 1 connects to the arc-shaped docking track 3, the birdhook drive device 4 releases the carrier 8, allowing the carrier 8 to transition from the transverse track 1 to the arc-shaped docking track 3 under inertia. When the carrier 8 reaches the arc-shaped docking track 3, a brush drive device 5 pushes the carrier 8 to transport it on the arc-shaped docking track 3. When the carrier 8 is pushed to the end where the arc docking track 3 connects to the longitudinal track 2, the carrier 8 transitions from the arc docking track 3 to the longitudinal track 2 under the action of inertia. When the carrier 8 reaches the longitudinal track 2, the bird hook drive device 4 located on one side of the longitudinal track 2 loads the carrier 8 and pulls the carrier 8 to transport it on the longitudinal track 2 until the carrier 8 reaches the end of the longitudinal track 2 away from the end connected to the arc docking track 3. Then, the bird hook drive device 4 releases the carrier 8, causing the carrier 8 to leave the longitudinal track 2, thus completing the transportation of the carrier 8 on the production line.

[0035] The birdhook drive device 4, located on one side of the transverse track 1 and the longitudinal track 2, loads the carrier 8 onto the transverse track 1 and the longitudinal track 2 respectively, pulling the carrier 8 to transport it on the transverse track 1 and the longitudinal track 2. This provides a large driving force to the carrier 8, enabling the heavy carrier 8 to be transported on the transport track. Simultaneously, after loading the carrier 8, the birdhook drive device 4 limits its movement. By controlling the operating speed of the birdhook drive device 4, the transport speed of the carrier 8 on the transport track can be controlled. Alternatively, by controlling the start and stop of the birdhook drive device 4, the transport or stop of the carrier 8 on the transport track can be controlled. This controls the transport spacing of the carrier 8 on the transport track, preventing the carrier 8 from piling up on the transport track and facilitating operators to process and handle the materials carried in the carrier 8 at designated workstations on the transport track.

[0036] The transverse track 1 and the longitudinal track 2 are connected by an arc-shaped docking track 3 to facilitate a smoother transition of the vehicle 8 from the transverse track 1 to the longitudinal track 2. The vehicle 8 is propelled by a brush drive device 5 on the arc-shaped docking track 3 because the brush drive device 5 conforms better to the arc-shaped docking track 3, ensuring effective driving of the heavy vehicle 8 and thus guaranteeing efficient transport of the vehicle 8 on the transport track.

[0037] It is foreseeable that on the actual production line, the carrier 8 can also be transported from the longitudinal track 2 to the transverse track 1. That is, firstly, the bird hook drive device 4 located on one side of the longitudinal track 2 attaches the carrier 8 on the longitudinal track 2 and pulls the carrier 8 to the end where the longitudinal track 2 connects with the arc-shaped docking track 3. The bird hook drive device 4 then releases the carrier 8, and the carrier 8 enters the arc-shaped docking track 3 under the action of inertia. Then, the brush drive device 5 pushes the carrier 8 to transport on the arc-shaped docking track 3 until the carrier 8 reaches the end where the arc-shaped docking track 3 connects with the transverse track 1. The carrier 8 enters the transverse track 1 under the action of inertia. Then, the bird hook drive device 4 located on one side of the transverse track 1 attaches the carrier 8 on the transverse track 1 and pulls the carrier 8 to transport on the transverse track 1 until the carrier 8 reaches the end of the transverse track 1 away from the end connected with the arc-shaped docking track 3. The bird hook drive device 4 then releases the carrier 8, causing the carrier 8 to leave the transverse track 1. Whether the carrier 8 is transported from the transverse track 1 to the longitudinal track 2 or from the longitudinal track 2 to the transverse track 1 depends on the actual production situation. In the following text, we will use the example of the carrier 8 being transported from the transverse track 1 to the longitudinal track 2 for explanation.

[0038] In this embodiment, the brush driving device 5 includes a brush circulation track 51 disposed on one side of the arc-shaped docking track 3, a first driving wheel 52 disposed at the bottom of one end of the brush circulation track 51, a first driven wheel 53 disposed at the bottom of the other end of the brush circulation track 51, a first chain 54 with its two ends respectively sleeved on the first driving wheel 52 and the first driven wheel 53, a brush 55 vertically disposed on the first chain 54, and a first drive motor 56 disposed at the top of the brush circulation track 51 for driving the first driving wheel 52 to rotate. The brush circulation track 51 is an arc-shaped track with the same shape as the arc-shaped docking track 3. For specific effects, see [details omitted]. Figure 2 The brush drive device 5 includes a brush circulation track 51, a first drive wheel 52, a first driven wheel 53, a first chain 54, a brush 55, and a first drive motor 56. The brush circulation track 51 is fixed to one side of the arc-shaped docking track 3 and has the same shape as the arc-shaped docking track 3. The first drive wheel 52 is located at the bottom of one end of the brush circulation track 51, and the first driven wheel 53 is located at the bottom of the other end of the brush circulation track 51. One end of the first chain 54 is sleeved on the first drive wheel 52 and meshes with it, and the other end is sleeved on the first driven wheel 53 and meshes with it. The brush 55 extends vertically downward on the first chain 54. The first drive motor 56 is located at the top of the brush circulation track 51, and the shaft of the first drive motor 56 passes through the brush circulation track 51 and is fixedly connected to the first drive wheel 52.

[0039] When the first drive motor 56 starts, it drives the first drive wheel 52 to rotate. Through the meshing of the first drive wheel 52 with the first chain 54, the first chain 54 rotates. Through the meshing of the first chain 54 with the first driven wheel 53, the first driven wheel 53 rotates synchronously. This causes the brush 55 on the first chain 54 to rotate synchronously with the first chain 54, so that the brush 55 pushes the carrier 8 to move on the arc-shaped docking track 3. Since one end of the first chain 54 is sleeved on the first drive wheel 52 and the other end is sleeved on the first driven wheel 53, and the brush 55 is fixed on the link of the first chain 54, the brush circulation track 51 has the same shape as the arc-shaped docking track 3. Therefore, the first chain 54 is a slightly curved annular track shape, that is, the movement track of the brush 55 is a slightly curved annular track shape. This allows the brush 55 to fit well with the arc-shaped docking track 3 when it moves on the brush circulation track 51, thereby ensuring the driving effect of the heavy carrier 8 on the arc-shaped docking track 3.

[0040] In actual production, a roller-suspended carrier 8 is generally used in conjunction with the transport track. Therefore, in this application, the heavy-duty carrier 8 is also connected to the transverse track 1, the arc-shaped docking track 3, and the longitudinal track 2 via roller suspension. Connecting the carrier 8 to the transport track via roller suspension reduces friction between the carrier 8 and the transport track. This not only makes it easier for the bird hook drive device 4 to drive the heavy-duty carrier 8 on the transverse track 1 or the longitudinal track 2, but also, by adjusting the overall hardness of the brush 55 and adjusting the root of the brush 55 to be closer to the force point of the carrier 8, the brush 55 can also push the heavy-duty carrier 8 on the arc-shaped docking track 3.

[0041] In this embodiment, the birdhook drive device 4 includes a birdhook circulation track 41 located on one side of the transverse track 1 and the longitudinal track 2, a second drive wheel 42 located at the bottom of one end of the birdhook circulation track 41, a second driven wheel 43 located at the bottom of the other end of the birdhook circulation track 41, a second chain 44 with its two ends respectively sleeved on the second drive wheel 42 and the second driven wheel 43, a birdhook assembly 45 located on the second chain 44, and a second drive motor 46 located at the top of the birdhook circulation track 41. The birdhook assembly 45 is used to mount or release the carrier 8, and the second drive motor 46 is used to drive the second drive wheel 42 to rotate. See [link to specific details] for details. Figure 3 .

[0042] The birdhook drive device 4 includes a birdhook circulation track 41, a second driving wheel 42, a second driven wheel 43, a second chain 44, a birdhook assembly 45, and a second drive motor 46. A birdhook circulation track 41 is provided on one side of both the transverse track 1 and the longitudinal track 2. The second driving wheel 42 is located at the bottom of one end of the birdhook circulation track 41, and the second driven wheel 43 is located at the bottom of the other end of the birdhook circulation track 41. One end of the second chain 44 is sleeved on the second driving wheel 42, and the other end is sleeved on the second driven wheel 43, meshing with both the second driving wheel 42 and the second driven wheel 43 respectively. The birdhook assembly 45 is fixed to a link of the second chain 44. The second drive motor 46 is located at the top of the birdhook circulation track 41, and the shaft of the second drive motor 46 passes through the birdhook circulation track 41 and is fixedly connected to the second driving wheel 42.

[0043] When the carrier 8 is transported to the beginning of the transverse track 1, the birdhook assembly 45 located on one side of the transverse track 1 hooks the carrier 8 onto the transverse track 1. At this time, the second drive motor 46 is activated, driving the second drive wheel 42 to rotate. Through the engagement of the second drive wheel 42 with the second chain 44, the second chain 44 is driven to rotate. In turn, through the engagement of the second chain 44 with the second driven wheel 43, the second driven wheel 43 rotates synchronously. This causes the birdhook assembly 45 on the second chain 44 to rotate synchronously with the second chain 44 on the birdhook circulation track 41, thereby pulling the carrier 8 on the transverse track 1. When the carrier 8 is transported to the end of the transverse track 1, the birdhook assembly 45 releases the carrier 8, allowing the carrier 8 to be transported to the arc docking track 3 under the action of inertia. When the carrier 8 is transported from the arc docking track 3 to the beginning of the longitudinal track 2, the process of the birdhook assembly 45 located on one side of the longitudinal track 2 driving the carrier 8 to move on the longitudinal track 2 is the same as that of the transverse track 1.

[0044] It is foreseeable that the second chain 44 is in the shape of a circular track, meaning that the bird hook assembly 45 moves cyclically along the circular track on the bird hook circulation track 41. Therefore, after transporting a carrier 8 from the beginning of the transverse track 1 or the longitudinal track 2 to the end of the transverse track 1 or the longitudinal track 2, the bird hook assembly 45 returns to the beginning of the transverse track 1 or the longitudinal track 2 via the bird hook circulation track 41, driving another carrier 8 to be transported on the transverse track 1 or the longitudinal track 2. This allows the bird hook assembly 45 to be reused, thereby reducing production costs and saving resources. Furthermore, in this application, multiple bird hook assemblies 45 can be set to run simultaneously on the bird hook circulation track 41, so that multiple bird hook assemblies 45 respectively drive multiple carriers 8 to be transported on the transverse track 1 or the longitudinal track 2, thereby improving the working efficiency of this device.

[0045] In this embodiment, the bird hook assembly 45 includes a bird hook seat 451 fixed on the second chain 44, a bird hook 452 rotatably connected to the bird hook seat 451 at one end, and a torsion spring 453 abutting against the bird hook 452 at one end and against the bird hook seat 451 at the other end. See below for specific effects. Figure 4 The bird hook assembly 45 includes a bird hook seat 451, a bird hook 452, and a torsion spring 453. The bird hook seat 451 is fixed to a link of the second chain 44. One end of the bird hook 452 is rotatably connected to the bird hook seat 451. One end of the torsion spring 453 abuts against the bird hook seat 451, and the other end abuts against the bird hook 452. When the torsion spring 453 opens, the end of the bird hook 452 away from the rotatably connected bird hook seat 451 presses down, hooking the carrier 8 on the transverse track 1 or the longitudinal track 2. Thus, when the bird hook 452 moves on the bird hook circulation track 41, it pulls the carrier 8 to transport on the transverse track 1 or the longitudinal track 2. When the torsion spring 453 contracts, the end of the bird hook 452 away from the rotatably connected bird hook seat 451 lifts up, releasing the carrier 8. Thus, the carrier 8 at the end of the transverse track 1 connects with the arc-shaped docking track 3, and the carrier 8 at the end of the longitudinal track 2 connects with the next docking track, continuing the transport of subsequent processes.

[0046] In this embodiment, a mounting post 81 is provided on one side of the carrier 8, and a mounting groove 4521 for engaging with the mounting post 81 is provided at the end of the bird hook 452 that is rotatably connected to the bird hook seat 451. See the specific effect below. Figure 4 and Figure 5 A hook post 81 is provided on one side of the vehicle 8. The end of the bird hook 452 that is rotatably connected to the bird hook seat 451 is provided with a hook groove 4521. The bird hook drive device 4 also includes a vehicle release plate 47 and a crash plate 48. The vehicle release plate 47 is provided at one end of the bird hook circulation track 41 near the end of the transverse track 1 or the longitudinal track 2. The crash plate 48 is provided at one end of the bird hook circulation track 41 near the beginning of the transverse track 1 or the longitudinal track 2. Both the vehicle release plate 47 and the crash plate 48 are provided with inclined portions 471.

[0047] After the birdhook assembly 45 transports the carrier 8 from the starting end to the end of the transverse track 1 on one side of the birdhook circulation track 41, it returns to the starting end of the transverse track 1 via the other side of the birdhook circulation track 41. A crash barrier 48 is provided at one end of the birdhook circulation track 41 near the starting end of the transverse track 1. When the birdhook 452 returns to one side of the birdhook circulation track 41 via the crash barrier 48, it abuts against the inclined portion 471 of the crash barrier 48. Under the contact of the inclined portion 471 of the crash barrier 48, the torsion spring 453 contracts, causing the birdhook 452 to rise away from the end rotatably connected to the birdhook seat 451, preventing the birdhook 452 from colliding with the carrier that has just entered the transverse track 1. The hook 452 abuts or collides with the hook 8 and the hook 452 reaches the side of the hook circulation track 41 after passing the anti-collision plate 48. At this time, the abutment of the inclined part 471 of the anti-collision plate 48 against the hook 452 disappears. The torsion spring 453 opens under its own elastic force, causing the hook 452 to press down away from the end that is rotatably connected to the hook seat 451. This causes the hook groove 4521 on the hook 452 to cooperate with the hook 81 on the side of the carrier 8, so that the hook assembly 45 can be mounted on the carrier 8. Then, when the hook 452 moves on the side of the hook circulation track 41, it pulls the carrier 8 from the beginning of the transverse track 1 to the end.

[0048] When the vehicle 8 reaches the end of the transverse track 1, the bird hook 452 reaches the end of the bird hook circulation track 41 near the end of the transverse track 1. A vehicle release plate 47 is located at the end of the bird hook circulation track 41 near the end of the transverse track 1, and the vehicle release plate 47 also has an inclined portion 471. When the bird hook 452 passes the vehicle release plate 47, it abuts against the inclined portion 471 of the vehicle release plate 47. Under the abutting action of the inclined portion 471 of the vehicle release plate 47, the torsion spring 453 contracts, causing the end of the bird hook 452 away from the rotatably connected bird hook seat 451 to rise, thereby allowing the hook groove 4521 of the bird hook 452 to engage with the hook on one side of the vehicle 8. The connecting post 81 disengages, releasing the carrier 8, allowing it to enter the arc-shaped docking track 3 under inertia. After passing the carrier release plate 47, the bird hook 452 reaches the other side of the bird hook circulation track 41. At this point, the abutment of the inclined portion 471 of the carrier release plate 47 against the bird hook 452 disappears, and the torsion spring 453 opens under its own elastic force, causing the bird hook 452 to press down away from the end rotatably connected to the bird hook seat 451. The bird hook 452 continues to move on the bird hook circulation track 41, then returns to the starting end of the transverse track 1 via the other side of the bird hook circulation track 41, repeating the above actions to drive the next carrier 8. Similarly, the bird hook 452 located on one side of the longitudinal track 2 drives the carrier 8 on the longitudinal track 2 in the same manner.

[0049] In this embodiment, the birdhook drive device 4 also includes a chain tensioning assembly 49 disposed at the top of the other end of the birdhook circulation track 41 for tensioning the second chain 44. See details for specific effects. Figure 4In this application, the movement of the bird hook 452 on the bird hook circulation track 41 is driven by the second chain 44. Since the chain is used for transmission, if the chain is too tight, it will reduce the chain transmission capacity and the chain's service life. Conversely, if the chain is too loose, it will cause excessive chain sag, resulting in poor meshing and chain vibration. Therefore, the bird hook drive device 4 also includes a chain tensioning component 49, which is located at the top of the other end of the bird hook circulation track 41. This component is used to adjust the tension of the second chain 44, thereby ensuring the transmission efficiency and service life of the second chain 44.

[0050] In this embodiment, the chain tensioning assembly 49 includes a mounting base 491 fixed to the top of the other end of the birdhook circulation track 41, a fixed gear 492 fixed to the bottom of the mounting base 491, and a movable gear 493 that can move laterally at the bottom of the mounting base 491. The second driven wheel 43 is located at the bottom of the mounting base 491 and is longitudinally aligned with the second driving wheel 42. One end of the second chain 44 is sleeved on the second driving wheel 42, and the other end is simultaneously sleeved on the fixed gear 492, the movable gear 493, and the second driven wheel 43. See [the diagram for details]. Figure 3 and Figure 6 The chain tensioning assembly 49 includes a mounting base 491, a fixed gear 492, and a movable gear 493. The fixed gear 492, the movable gear 493, and the second driven wheel 43 are all located at the bottom of the mounting base 491 and are distributed in a triangular shape at the bottom of the mounting base 491. The second driven wheel 43 is longitudinally aligned with the second driving wheel 42 at the bottom of the mounting base 491. The movable gear 493 can move laterally at the bottom of the mounting base 491. One end of the second chain 44 is sleeved on the second driving wheel 42, and the other end is simultaneously sleeved on the fixed gear 492, the movable gear 493, and the second driven wheel 43. The tension of the second chain 44 can be adjusted by adjusting the lateral movement of the movable gear 493.

[0051] In this embodiment, a diversion track 6 is further included, with one end connected to the end of a transverse track 1 and the other end connected to the end of an arc-shaped docking track 3 or another transverse track 1. A reversing device 7 is also included to adjust the connection between the diversion track 6 and the ends of the arc-shaped docking track 3 and the other transverse track 1, respectively. See below for specific effects. Figure 1 When the carrier 8 reaches the end of the transverse track 1, two paths may occur: one is to continue transverse transportation, and the other is to switch to longitudinal transportation. Therefore, this application also includes a diversion track 6. One end of the diversion track 6 is fixedly connected to the end of a transverse track 1, and the other end can be adjusted in direction by the reversing device 7. After the direction is adjusted, the reversing device 7 fixes the other end of the diversion track 6, thereby connecting one transverse track 1 with another transverse track 1 or an arc-shaped docking track 3, realizing the transportation of the carrier 8 in multiple directions and meeting the needs of actual production.

[0052] When the vehicle 8 is transported to the end of a transverse track 1, if it is necessary to continue transverse transport, the direction of the other end of the diversion track 6 is adjusted by the reversing device 7 and then fixed, so that the diversion track 6 is connected to the initial end of another transverse track 1, thereby enabling the vehicle 8 to transition from one transverse track 1 to another transverse track 1 and continue transverse transport; if it is necessary to switch to longitudinal transport, the direction of the other end of the diversion track 6 is adjusted by the reversing device 7 and then fixed, so that the diversion track 6 is connected to the initial end of the arc docking track 3, thereby enabling the vehicle 8 on the transverse track 1 to pass through the diversion track 6 and the arc docking track 3 in sequence and enter the longitudinal track 2 for longitudinal transport.

[0053] In this embodiment, the diversion track 6 is a flexible track. The reversing device 7 includes a fixed base 71 located at one end of a transverse track 1, another transverse track 1, and an arc-shaped connecting track 3, close to each other. A swing rod 72 is rotatably connected to the fixed base 71 at one end. A cylinder 73, mounted on the fixed base 71, drives the swing rod 72 to rotate a certain arc. A connecting post 74 connects the diversion track 6 and the swing rod 72. The fixed base 71 has an arc-shaped hole 711. The extended end of the cylinder 73 is fixedly connected to the end of the swing rod 72 away from the rotatably connected fixed base 71. One end of the connecting post 74 is fixedly connected to the end of the diversion track 6 away from the end of a transverse track 1, and the other end passes through the arc-shaped hole 711 and is fixedly connected to the end of the swing rod 72 away from the rotatably connected fixed base 71. See the specific effect below. Figure 1 and Figure 7 The reversing device 7 includes a fixed base 71, a rocker arm 72, a cylinder 73, and a connecting column 74. The fixed base 71 is located at one end of a transverse track 1, the other end of the transverse track 1, and the arc-shaped docking track 3 that are close to each other, namely the end of the transverse track 1, the initial end of the other transverse track 1, and the initial end of the arc-shaped docking track 3.

[0054] The rocker arm 72 and the cylinder 73 are mounted on the top of the fixed base 71. The fixed base 71 has an arc-shaped hole 711. One end of the rocker arm 72 is rotatably connected to the fixed base 71. The fixed end of the cylinder 73 is fixed to the fixed base 71, and the extended end is fixedly connected to the end of the rocker arm 72 away from the rotatably connected end of the fixed base 71. One end of the connecting column 74 is connected to the diversion rail 6, and the other end passes through the arc-shaped hole 711 and is fixedly connected to the end of the rocker arm 72 away from the rotatably connected end of the fixed base 71. Thus, when the extended end of the cylinder 73 extends or retracts, it drives the rocker arm 72 away from the end connected to the fixed base 71 to rotate clockwise or counterclockwise by a certain angle with the end rotatably connected to the fixed base 71 as the center. Since the diversion track 6 is a flexible track, when the end of the swing arm 72 that is away from the end connected to the fixed seat 71 rotates clockwise or counterclockwise by a certain angle, it drives the connecting column 74 to rotate clockwise or counterclockwise along the arc hole 711 by a certain angle, thereby driving the diversion track 6 away from the end connected to a transverse track 1 and connected to another transverse track 1 or an arc-shaped docking track 3.

[0055] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.
