[0032] Embodiment

[0033] Refer to Figures 1 - 8, is the track switch disclosed by the present invention, including a circular transportation line 1, a heavy-duty track switch 2, and a light-duty track switch 3; through the mutual cooperation of the heavy-duty track switch 2 and the light-duty track switch 3, the present invention realizes the off-line function of the tipping conveyor on the circular transportation line 1.

[0034] Specifically, the heavy-duty track switch 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. A heavy-duty straight rail 7 and a heavy-duty curved rail 8 are arranged on the two linear guide rails 6, and the heavy-duty curved rail 8 can coincide with the outer arc-shaped transportation line 101 of the circular transportation line 1, and the heavy-duty straight rail 7 can coincide with the outer straight-shaped transportation line 102 of the circular transportation line 1. A heavy-duty rail frame 9 is connected to the lower surfaces of the heavy-duty straight rail 7 and the heavy-duty curved rail 8, and a driving component for driving its own sliding is installed on the heavy-duty rail frame 9.

[0035] Furthermore, the driving component includes a driving motor 10, a straight rack 11, and a gear 12. An installation base 13 is provided on the ground or on a steel structure. The driving motor 10 is installed on the installation base 13, the gear 12 is installed at the output end of the driving motor 10, the straight rack 11 is installed on the top of the heavy-duty rail frame 9 and is perpendicular to the heavy-duty straight rail 7, and its tooth end is upward and meshes with the gear 12.

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

[0037] When the driving motor 10 is started, the gear 12 rotates and converts the rotational motion into a linear motion through meshing with the straight rack 11, pushing the heavy-duty rail frame 9 connected to the straight 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 installed 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 groups of positioning components are installed on the side of the heavy-duty rail frame 9, and the distance between the two groups 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 component includes four symmetrically arranged positioning wheels 14 in pairs, a positioning hole is formed between the four positioning wheels 14, and a telescopic positioning rod 15 that can be inserted into the positioning hole is also provided on the ground (the telescopic positioning rod 15 is a well-known technology in the art, and its principle and structure will not be elaborated here in detail). Through the cooperation of the telescopic positioning rod and the positioning hole, the positioning of the heavy-duty track switch 2 can be realized, preventing the heavy-duty track switch 2 from moving or shaking after the tipping conveyor walks to the position on the heavy-duty straight rail 7 or the heavy-duty curved rail 8.

[0039] Further, 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 railway switch 2, and the second support wheel 17 is used to strengthen the supporting 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 turnover machine is on the heavy-duty straight rail 7 or the heavy-duty curved rail 8, and at the same time reducing the supporting force of the linear guide rail 6 and increasing the service life of the linear guide rail 6.

[0040] Further, dead stops 18 are provided at both ends of the two linear guide rails 6, and the dead stops 18 are provided to prevent the heavy-duty rail frame 9 from sliding out of the linear guide rails 6.

[0041] The light-duty railway switch 3 includes a first leg 19 and a third leg 20. A light-duty rail 21 is provided on the first leg 19 and the third leg 20, and the light-duty rail 21 is connected to the inner straight conveyor line 103 of the circular conveyor line 1 and is located on the same straight line; the light-duty rail 21 is used to support the light-duty side walking wheels of the turnover conveyor, so that the turnover conveyor goes to or returns from the off-line position to the main line.

[0042] Specifically, the light-duty rail 21 includes a fixed section 22 and a rotating section 23. Among them, a plurality of first legs 19 are provided, and the fixed end is provided on the plurality of first legs 19, and the fixed end is connected to the inner straight conveyor line 103 of the circular conveyor line 1 and is located on the same straight line. One end of the rotating section 23 is rotatably provided on the third leg 20, and the other end of the rotating section 23 can be placed on the first leg 19. A cylinder assembly 24 capable of driving the rotating section 23 to rotate is further provided on the third leg 20. Specifically, a support frame 25 is provided on the side of the third leg 20. A rotating shaft 26 is provided between one end of the rotating section 23 and the support frame 25, and a bearing 27 is provided on the rotating shaft 26 to reduce the frictional resistance of rotation. Further, a support bushing 28 is sleeved on the circumferential surface of the rotating shaft 26 and the bearing 27, and the rotating shaft 26 rotates in the support bushing 28. A support plate 29 for supporting the rotating section 23 is fixed on the top of the rotating shaft 26; the support plate 29 is connected to the rotating section 23, and the rotating shaft 26, the support plate 29 and the rotating section 23 rotate together in the support bushing 28.

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

[0044] Specifically, the cylinder assembly 24 includes a cylinder bracket 30 mounted on the third leg 20. An angle steel 31 is mounted on the cylinder bracket 30, and a horizontally arranged cylinder body 32 is 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 leg 34 is also provided on the bottom surface, and the second leg 34 is located on the rotation path of the rotating section 23;

[0045] Specifically speaking: Under normal conditions, the telescopic end of the cylinder body 32 is always in the retracted state. The end of the rotating end far from the rotation axis 26 is located on the second bracket, so that the rotating section 23 is staggered from the fixed end, and the light load track 21 is in a disconnected state. At the same time, the heavy load curved rail 8 of the heavy load turnout 2 coincides with the outer arc-shaped transport line 101 of the circular transport line 1;

[0046] When the tilter 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 rotation axis 26. The rotating section 23 rotates counterclockwise around the rotation axis 26, so that the free end of the rotating section 23 disengages from the second leg 34. When the cylinder is fully extended, the free end of the rotating section 23 is accurately docked and fixed, and the light load track 21 forms a continuous straight line and aligns with the inner straight transport line 103. At this time, the free end of the rotating section 23 is placed on the first bracket;

[0047] At the same time, the drive motor 10 is started to switch the positions of the heavy load straight rail 7 and the heavy load curved rail 8, so that the heavy load curved rail 8 can be staggered from the outer arc-shaped transport line 101 of the circular transport line 1, and the heavy load straight rail 7 is connected to the outer straight transport line 102 of the circular transport line 1;

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

[0049] Compared with the turntable transportation, the present invention can run along the straight track and the arc track, simplifies the structure and has higher reliability. The track turnout of the offline function of the original tilter conveyor system with a turntable is no longer applicable to the self-rotating tilter conveyor system. Therefore, a new track turnout is invented to realize the offline function of the tilter conveyor for problems, temporary storage or maintenance of the tilter conveyor. When there is a problem with the tilter conveyor, the faulty tilter conveyor can be taken offline in time through the track turnout, ensuring the flexibility of the self-rotating tilter conveyor system.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
