Description

Technical Field

[0001] This utility model relates to the field of coating and conveying technology, and in particular to railway turnouts. Background Technology

[0002] Currently, the most advanced pretreatment electrophoresis conveying method is a tilting conveyor. This conveyor uses a combination of heavy-duty and light-duty tracks, circulating between them. When the tilting conveyor malfunctions, requires temporary storage, or needs maintenance, it must be moved to an offline position.

[0003] Chinese patent CN208585707U discloses a car body conveying system and a car body pretreatment and electrophoresis system. The tilting machine can only run in a straight line along the track. Switching between rotating lines requires the addition of a turntable. At the same time, the tilting machine to the offline position also requires the turntable and a light-load track switch to work together.

[0004] Currently, there is a self-rotating tilting conveyor system that eliminates the turntable, allowing the tilting conveyor to run along both straight and curved tracks. Existing offline-function track switches are no longer suitable for this self-rotating tilting conveyor system. When the tilting conveyor malfunctions, requires temporary storage, or needs maintenance, a new type of track switch is needed to enable the tilting conveyor to operate offline.

The heavy-load track switch and the light-load track switch cooperate with each other to enable the tilting conveyor to circulate on the circular transport line, go to the offline position, or return to the main line from the offline position.

[0008] Further configured as follows: the heavy-duty track turnout includes a left support frame and a right support frame arranged in parallel, which can be installed on a steel platform or on the ground. Both the left support frame and the right support frame are provided with linear guide rails, and the two linear guide rails are provided with heavy-duty straight rails and heavy-duty curved rails. The heavy-duty curved rails can coincide with or be offset from the outer arc-shaped transport line of the circular transport line, and the heavy-duty straight rails can connect with or be offset from the outer straight transport line of the circular transport line.

[0009] The configuration is further defined as follows: a heavy-duty rail frame is connected to the lower surface of the heavy-duty straight rail and the heavy-duty curved rail, and a driving component is installed on the heavy-duty rail frame. The driving component is used to drive the heavy-duty rail frame to slide along the linear guide rail to realize the position switching between the heavy-duty straight rail and the heavy-duty curved rail.

[0010] The drive assembly is further configured as follows: the drive assembly includes a drive motor, a rack and pinion, and a gear, and also includes a mounting base. The drive motor is mounted on the mounting base, the gear is mounted on the output end of the drive motor, and the rack is mounted on the top of the heavy-duty rail frame and perpendicular to the heavy-duty straight rail, with its tooth ends facing upward and meshing with the gear.

[0011] Further configured as follows: the light-load track turnout includes a first leg and a third leg, on which a light-load track is provided. The light-load track is connected to the inner straight transport line of the circular transport line and is located on the same straight line. The light-load track is used to support the light-load side traveling wheel of the tilting conveyor, so that the tilting conveyor can go to the offline position or return from the offline position to the main line.

[0012] Further configuration: The light-load track includes a fixed section and a rotating section. Multiple first legs are provided, and the fixed end is provided on multiple first legs. The fixed end is connected to the inner straight transport line of the circular transport line and is located on the same straight line. One end of the rotating section is rotatably provided on the third leg, and the other end of the rotating section can be placed on the first leg. A cylinder assembly capable of driving the rotating section to rotate is also provided on the third leg.

[0013] The cylinder assembly is further configured such that: a cylinder bracket is mounted on a third leg, an angle steel is mounted on the cylinder bracket, a horizontally arranged cylinder body is mounted on the angle steel, one end of the cylinder body is hinged to the angle steel, a connecting block is hinged to the telescopic end of the cylinder body, and the connecting block is fixed to the side wall of the rotating section, and a second leg is also provided on the bottom surface, and the second leg is located on the rotation path of the rotating section.

[0016] The configuration is further defined as follows: a first support wheel and a second support wheel are rotatably mounted on the heavy-duty rail frame, and both the first support wheel and the second support wheel are arranged parallel to the linear guide rail.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] This invention utilizes the cooperation of heavy-duty and light-duty turnouts to enable the tilt conveyor to be taken offline from the main line for temporary storage, maintenance, or repair, or to return to the main line from its offline position for renewed operation. This improves the system's flexibility and ease of maintenance. Compared to traditional turntable transportation methods, the turnout structure of this invention is simpler and more reliable. This not only reduces system complexity but also minimizes potential failure points, improving the stability and safety of the entire conveying system. The heavy-duty turnout uses a drive component to switch between heavy-duty straight and heavy-duty curved rails, while a positioning component ensures stability after track switching, preventing track movement or swaying, thus guaranteeing the smooth operation of the tilt conveyor on the track. This invention's turnout is suitable for self-rotating tilt conveyor systems, enabling timely offline removal of faulty tilt conveyors, ensuring normal system operation, and improving production efficiency.

[0032] Example

[0033] Reference Figures 1-8The present invention discloses a track turnout, which includes a circular transport line 1, a heavy-load track turnout 2, and a light-load track turnout 3. The present invention achieves the offline function of the tilting conveyor on the circular transport line 1 by the cooperation of the heavy-load track turnout 2 and the light-load track turnout 3.

[0034] Specifically, the heavy-duty rail turnout 2 includes a left support frame 4 and a right support frame 5 arranged in parallel, and both can be installed on a steel platform or on the ground. Linear guide rails 6 are provided on both the left support frame 4 and the right support frame 5. Heavy-duty straight rails 7 and heavy-duty curved rails 8 are provided on the two linear guide rails 6. The heavy-duty curved rail 8 can coincide with the outer arc-shaped transport line 101 of the circular transport line 1, and the heavy-duty straight rail 7 can coincide with the outer straight transport line 102 of the circular transport line 1. A heavy-duty rail frame 9 is connected to the lower surface of the heavy-duty straight rail 7 and the heavy-duty curved rail 8. A drive component for driving its own sliding is installed on the heavy-duty rail frame 9.

[0035] Furthermore, the drive assembly includes a drive motor 10, a rack 11, and a gear 12. A mounting base 13 is provided on the ground or a steel structure. The drive motor 10 is mounted on the mounting base 13, the gear 12 is mounted on the output end of the drive motor 10, and the rack 11 is mounted on the top of the heavy-duty rail frame 9 and perpendicular to the heavy-duty straight rail 7. Its tooth ends are set upward and mesh with the gear 12.

[0036] In this invention, the heavy-duty curved rail 8 is used for the cyclic operation of the tilting conveyor, and the heavy-duty straight rail 7 is used for the tilting conveyor to go to the offline position or return from the offline position to the main line.

[0037] When the drive motor 10 starts, the gear 12 rotates and, through meshing with the rack 11, converts the rotational motion into linear motion, pushing the heavy-duty rail frame 9 connected to the rack 11 to slide along the linear guide rail 6. Since both the heavy-duty straight rail 7 and the heavy-duty curved rail 8 are mounted on the heavy-duty rail frame 9, the movement of the heavy-duty rail frame 9 will synchronously drive the heavy-duty straight rail 7 and the heavy-duty curved rail 8 to move along the linear guide rail 6, thereby realizing the position switching of the heavy-duty straight rail 7 and the heavy-duty curved rail 8.

[0038] In this embodiment, two sets of positioning components are installed on the side of the heavy-duty rail frame 9. The distance between the two sets of positioning components is equal to the switching distance between the heavy-duty straight rail 7 and the heavy-duty curved rail 8. Specifically, the positioning components include four symmetrical positioning wheels 14, with positioning holes formed between the four positioning wheels 14. Telescopic positioning rods 15 that can be inserted into the positioning holes are also provided on the ground (telescopic positioning rods 15 are well-known technologies in the field, and their principles and structures will not be described in detail here). By cooperating with the positioning holes, the positioning of the heavy-duty rail switch 2 can be achieved, preventing the heavy-duty rail switch 2 from moving or shaking after the overturning conveyor has traveled to the position of the heavy-duty straight rail 7 or the heavy-duty curved rail 8.

[0039] Furthermore, a first support wheel 16 and a second support wheel 17 are rotatably mounted on the heavy-duty rail frame 9, and both the first support wheel 16 and the second support wheel 17 are arranged parallel to the linear guide rail 6. In this embodiment, the first support wheel 16 is used to increase the smoothness of the sliding movement of the heavy-duty rail turnout 2, and the second support wheel 17 is used to strengthen the support force of the heavy-duty straight rail 7 and the heavy-duty curved rail 8, preventing the heavy-duty straight rail 7 or the heavy-duty curved rail 8 from deforming when the tilting machine is on the heavy-duty straight rail 7 or the heavy-duty curved rail 8. At the same time, it also reduces the support force of the linear guide rail 6 and increases the service life of the linear guide rail 6.

[0040] Furthermore, dead stops 18 are provided at both ends of the two linear guide rails 6. The dead stops 18 are provided to prevent the heavy-duty rail frame 9 from running off the linear guide rails 6 when sliding.

[0041] The light-load track turnout 3 includes a first leg 19 and a third leg 20. A light-load track 21 is provided on the first leg 19 and the third leg 20. The light-load track 21 is connected to the inner straight transport line 103 of the circular transport line 1 and is located on the same straight line. The light-load track 21 is used to support the light-load side traveling wheel of the tilting conveyor, so that the tilting conveyor can go to the offline position or return to the main line from the offline position.

[0042] Specifically, the light-load track 21 includes a fixed section 22 and a rotating section 23. Multiple first support legs 19 are provided, with fixed ends mounted on these legs. These fixed ends are connected to and aligned with the inner straight transport line 103 of the circular transport line 1. One end of the rotating section 23 is rotatably mounted on a third support leg 20, and the other end can rest on a first support leg 19. A cylinder assembly 24 capable of driving the rotating section 23 is also provided on the third support leg 20. Specifically, a support is provided on the side of the third support leg 20. A rotating shaft 26 is provided between one end of the rotating section 23 and the supporting frame 25. A bearing 27 is provided on the rotating shaft 26 to reduce the frictional resistance of rotation. Furthermore, a supporting bushing 28 is sleeved on the circumferential surface of the rotating shaft 26 and the bearing 27. The rotating shaft 26 rotates within the supporting bushing 28. A supporting plate 29 for supporting the rotating section 23 is fixed on the top of the rotating shaft 26. The supporting plate 29 is connected to the rotating section 23, and the rotating shaft 26, the supporting plate 29, and the rotating section 23 rotate together within the supporting bushing 28.

[0043] A cylinder assembly 24 is provided on the third leg 20 to drive the rotating section 23 of the light-load rail 21 to rotate along the rotating axis 26.

[0044] Specifically, the cylinder assembly 24 includes a cylinder bracket 30 mounted on the third support leg 20, an angle steel 31 mounted on the cylinder bracket 30, and a horizontally arranged cylinder body 32 mounted on the angle steel 31. Specifically, one end of the cylinder body 32 is hinged to the angle steel 31, and a connecting block 33 is hinged to the telescopic end of the cylinder body 32. The connecting block 33 is fixed to the side wall of the rotating section 23. A second support leg 34 is also provided on the bottom surface, and the second support leg 34 is located on the rotation path of the rotating section 23.

[0045] Specifically: Under normal conditions, the telescopic end of the cylinder body 32 is always in a retracted state, and the end of the rotating end away from the rotating shaft 26 is located on the second bracket, so that the rotating section 23 is offset from the fixed end, the light-load track 21 is in a disconnected state, and at the same time, the heavy-load curved track 8 of the heavy-load track branch 2 coincides with the outer arc-shaped transport line 101 of the circular transport line 1.

[0046] When the tilting machine goes to the offline position or returns from the offline position to the main line, the telescopic end of the cylinder body 32 extends, pushing the hinged connecting block 33 to drive the side wall of the rotating section 23, forming a counterclockwise lever force centered on the rotating shaft 26. The rotating section 23 rotates counterclockwise around the rotating shaft 26, causing the free end of the rotating section 23 to detach from the second support leg 34. When the cylinder is fully extended, the free end of the rotating section 23 is precisely docked and fixed, and the light-load track 21 forms a continuous straight line, aligned with the inner straight transport line 103. At this time, the free end of the rotating section 23 is placed on the first support.

[0047] At the same time, the drive motor 10 starts to switch the position of the heavy-duty straight rail 7 and the heavy-duty curved rail 8, so that the heavy-duty curved rail 8 can be offset from the outer arc-shaped transport line 101 of the circular transport line 1, and the heavy-duty straight rail 7 can be connected to the outer straight transport line 102 of the circular transport line 1.

[0048] The self-rotating tilting conveyor system forms an offline track through the cooperation of heavy-load track switch 2 and light-load track switch 3, thereby realizing the offline function of the tilting conveyor. This allows the tilting conveyor to run to the offline position for temporary storage, maintenance, or repair; or at this time, the tilting conveyor can return from the offline position to the main line and start circulating around the circular track again.

[0049] Compared to turntable transport, this invention can run along straight and curved tracks, simplifying the structure and increasing reliability. The existing track switches with offline functionality in turntable-equipped tilting conveyor systems are no longer suitable for self-rotating tilting conveyor systems. Therefore, this invention provides a new track switch to realize the offline function of the tilting conveyor, used for when the tilting conveyor malfunctions, for temporary storage, or for maintenance. When a problem occurs with the tilting conveyor, the faulty reverse conveyor can be promptly taken offline via the track switch, ensuring the flexibility of the self-rotating tilting conveyor system.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
