[0035] The utility model is described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-4 As shown, the crawler conveying mechanism includes an upper crawler member 1 and a lower crawler member 10 arranged at intervals, a transmission mechanism is arranged between the upper crawler member 1 and the lower crawler member 10, the transmission mechanism includes an active driving member 4 and a driven driving member 5, the active driving member 4 is in transmission connection with the driven driving member 5, when the active driving member 4 moves, the driven driving member 5 moves at the same time, the active driving member 4 drives the lower crawler member 10 to move, and the driven driving member 5 drives the upper crawler member 1 to move; under the drive of the active driving member 4, the lower crawler member 10 moves, and at the same time, the driven driving member 5 transmission-connected with the active driving member 4 moves at the same time, so that the upper crawler member 1 also moves at the same time, the upper crawler member 1 and the lower crawler member 10 move at the same time, and the upper and lower crawler transmission mode can be realized by an active power, the structural design defects are optimized, the consistency of the crawler operation is improved, the production efficiency is improved, and the cost of the equipment is reduced.

[0037] Specifically, the upper track member 1 includes an upper track shoe 11 and upper transmission wheels 12 installed at both ends of the upper track shoe 11, and an upper conveying track 13 is nested between the two upper transmission wheels 12; the lower track member 10 includes a lower track shoe 14 and lower transmission wheels 15 installed at both ends of the lower track shoe 14, and a lower conveying track 16 is nested between the two lower transmission wheels 15.

[0038] A height adjustment mechanism 2 capable of adjusting the distance between the upper track member 1 and the lower track member 10 is also provided between the upper track member 1 and the lower track member 10. The height adjustment mechanism 2 can adjust the distance between the upper track member 1 and the lower track member 10, so that the lower track member 10 can transport goods of different heights, realize simultaneous transportation of the upper and lower layers, and further improve the transportation efficiency.

[0039] Specifically, the height adjustment mechanism 2 includes a longitudinally arranged adjustment bracket 21, which is installed on the lower track member 10. The adjustment bracket 21 is installed with a longitudinally arranged telescopic driving member 22, and the driving end of the telescopic driving member 22 is connected to the upper track plate 11; when the driving end of the telescopic driving member 22 performs telescopic movement, the upper track member 1 can move longitudinally without affecting the normal operation of the lower track member 10, thereby ensuring the transportation stability during adjustment, so that the goods during transportation can be transported to areas of different heights for subsequent transportation.

[0040] Furthermore, the adjusting bracket 21 includes a top plate 27 and a guide rod 23 installed at the bottom of the top plate 27. The upper track shoe 11 is formed with a guide hole 24 for the guide rod 23 to pass through. The bottom of the guide rod 23 is connected to the lower track shoe 14. When the driving end of the telescopic drive member 22 performs telescopic movement, the guide rod 23 will slide and cooperate with the guide hole 24 of the upper track shoe 11, so that the upper track shoe 11 can move longitudinally, and the height of the upper conveying crawler 13 installed on the upper track shoe 11 can be adjusted without affecting the normal operation of the upper conveying crawler 13.

[0041] Furthermore, the telescopic drive member 22 is a lifting cylinder installed on the top plate 27, and a connecting seat 25 is installed at the bottom of the piston rod of the lifting cylinder. The connecting seat 25 is formed with a movable space 26 for the upper conveying crawler 13 to pass through. The bottom of the connecting seat 25 is connected to the upper track plate 11, and the upper conveying crawler 13 moves normally through the movable space 26. Therefore, whether it is lifted or not, it will not affect the normal operation of the upper conveying crawler 13, and no friction or collision will occur.

[0042] Preferably, there are multiple lifting cylinders to improve the stability of lifting.

[0043] The upper track member 1 is also provided with a tensioning adjustment component 3 for adjusting the tension of the upper conveying crawler 13. The tensioning adjustment component 3 includes a tensioning seat 31 for installing one of the upper transmission wheels 12. The tensioning seat 31 is formed with an adjustment groove 32 along the length direction. The adjustment groove 32 is slidably installed with an adjustment shaft 33. The upper transmission wheel 12 can be rotatably installed on the adjustment shaft 33. The adjustment shaft 33 is arranged perpendicular to the adjustment groove 32. When the adjustment shaft 33 moves along the length direction of the adjustment groove 32, one of the upper transmission wheels 12 installed on the adjustment shaft 33 will move along the length direction of the upper track plate 11. Accordingly, the tension of the upper transmission crawler 13 nested between the two upper transmission wheels 12 is adjusted accordingly to prevent it from being too loose and causing internal concave collapse during transportation.

[0044] Furthermore, the tensioning seat 31 is respectively located on both sides of the upper transmission wheel 12, and the adjusting shaft 33 is formed with a top contact surface 34 and a bottom contact surface 35 parallel to the adjusting groove 32. The adjusting shaft 33 slides with the adjusting groove 32 through the top contact surface 34 and the bottom contact surface 35. The top contact surface 34 and the bottom contact surface 35 are parallel to each other, which can prevent the adjusting shaft 33 from rotating. When the adjusting shaft 33 moves, it can slide with the adjusting groove 32 through the top contact surface 34 and the bottom contact surface 35 to ensure the stability of the adjustment.

[0045] The tensioning seat 31 is equipped with an adjusting rod 36 that can move along the length direction of the adjusting slot 32. The adjusting rod 36 is connected to the adjusting shaft 33. When the adjusting rod 36 moves along the length direction of the adjusting slot 32, it can drive the adjusting shaft 33 to move to achieve tension adjustment.

[0046] In one embodiment, the adjusting rod 36 is a threaded rod, and the adjusting shaft 33 is formed with a threaded hole 37 that is threadably matched with the threaded rod. When the adjusting rod 36 is rotated, the adjusting shaft 33 can move along the length direction of the threaded rod.

[0047] In one embodiment, the adjusting rod 36 is a threaded rod, and the tensioning seat 31 is formed with a threaded hole 37 that cooperates with the thread of the threaded rod. The end of the adjusting rod 36 is connected to the adjusting shaft 33 through a bearing seat 58. When the adjusting rod 36 is rotated, the adjusting rod 36 can move along the length direction of the threaded rod, thereby driving the adjusting shaft 33 to move along the length direction of the threaded rod.

[0048] The active driving member 4 includes a main shaft plate 43 and a driving shaft 41 installed on the main shaft plate 43. The driving shaft 41 is connected to the lower transmission wheel 15. The driving shaft 41 is installed with a first driving gear 42. The main shaft plate 43 is also installed with a first transmission shaft 44. The first transmission shaft 44 is installed with a second driving gear 45 meshing with the first driving gear 42. When the driving shaft 41 rotates, the first driving gear 42 installed on the driving shaft 41 and the lower transmission wheel 15 rotate at the same time, and the lower crawler member 10 moves. At the same time, the first driving gear 42 drives the second driving gear 45 to rotate accordingly.

[0049] The driven driving member 5 includes a driven plate 51 and a driven shaft 52 installed on the driven plate 51. The driven shaft 52 is connected to the upper transmission wheel 12. The driven shaft 52 is installed with a first driven gear 53. The first driven gear 53 and the second driving gear 45 are meshed for transmission. Since the first driven gear 53 and the second driving gear 45 are meshed for transmission, when the second driving gear 45 rotates, the driven shaft 52 is driven to rotate. The driven shaft 52 drives the upper transmission wheel 12 to rotate, so that the upper crawler member 1 moves and moves simultaneously with the lower crawler.

[0050] Specifically, an intermediate transmission gear 54 is arranged beside the first driven gear 53, and a second transmission shaft 46 is installed on the intermediate transmission gear 54. A first movable sleeve 55 is nested between the second transmission shaft 46 and the first transmission shaft 44, and the intermediate transmission gear 54 can swing around the driving shaft 41 through the first movable sleeve 55; when the angle between the upper track member 1 and the lower track member 10 is adjusted, the first movable sleeve 55 will swing, so that the first movable sleeve 55 swings around the driving shaft 41. During the swinging, the second driving gear 45 installed on the first transmission shaft 44 always keeps meshing with the first driving gear 42, and will not affect the transmission performance.

[0051] Similarly, a second movable sleeve 56 is nested between the second transmission shaft 46 and the driven shaft 52, and the intermediate transmission gear 54 can swing around the driven shaft 52 through the second movable sleeve 56; when the angle between the upper crawler member 1 and the lower crawler member 10 is adjusted, the second movable sleeve 56 will swing, so that the second movable sleeve 56 swings around the driven shaft 52. During the swing, the second driving gear 45 installed on the driven shaft 52 always keeps meshing with the first driven gear 53, which will not affect the transmission performance. During the rising and falling process, there will be no pulling, friction, or abnormal noise on the chain and the rubber block.

[0052] Preferably, the first movable sleeve 55 and the second movable sleeve 56 are both formed with an axial hole 57, and the axial hole 57 is installed with a bearing seat 58. The first movable sleeve 55 is movably connected to the first transmission shaft 44 and the second transmission shaft 46 respectively through the bearing seat 58, and the second movable sleeve 56 is movably connected to the second transmission shaft 46 and the driven shaft 52 respectively through the bearing seat 58; since the bearing seat 58 is installed in the axial hole 57, when the driving shaft 41 and the driven shaft 52 rotate, the first movable sleeve 55 and the second movable sleeve 56 will not swing and maintain their posture. Only when the angle between the upper track member 1 and the lower track member 10 is adjusted, the first movable sleeve 55 and the second movable sleeve 56 will swing accordingly to form a corresponding angle.

[0053] The transmission mechanism also includes a power mechanism 6 for driving the active shaft 41 to rotate. The power mechanism 6 includes a servo motor 61 and a reducer 62 that is transmission-connected to the servo motor 61. The output end of the reducer 62 is vertically aligned with the active shaft 41. A transmission synchronous belt 63 is nested between the output end of the reducer 62 and the active shaft 41. The power source is the servo motor 61. The servo motor 61 and the reducer 62 cooperate to drive the driving end of the reducer 62 to rotate, and the active shaft 41 is driven to rotate through the transmission synchronous belt 63.

[0054] The power mechanism 6 also includes a tightening mechanism for adjusting the tension of the transmission synchronous belt 63. The tightening mechanism includes a tightening bracket 64 and a mounting plate 65 for mounting the tightening bracket 64. The tightening bracket 64 is installed with a tightening wheel 66 that cooperates with the transmission synchronous belt 63. The tightening bracket 64 can adjust its position laterally to adjust the tension of the transmission synchronous belt 63. The tightening wheel 66 cooperates with the transmission synchronous belt 63, so that the transmission synchronous belt 63 can move in a transmission manner. Subsequently, the position of the tightening bracket 64 can be moved to change the transmission tension of the tightening wheel 66 and the transmission synchronous belt 63, thereby maintaining the stability of the transmission.

[0055] Preferably, the mounting plate 65 is formed with a plurality of tightening holes 67 along the length direction, and the tightening bracket 64 is formed with a connecting hole that cooperates with the tightening hole 67. The tightening bracket 64 cooperates with one of the tightening holes 67 through the connecting hole and a connecting bolt is inserted therein, thereby being able to adjust the lateral installation position of the tightening bracket 64, so that the transmission tension of the tightening wheel 66 and the transmission synchronous belt 63 changes, thereby maintaining the stability of the transmission.

[0056] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0057] The above contents are only preferred embodiments of the present invention.
