[0018] 1. The hydraulic stepping traction device, when it is necessary to transport items, the horizontal hydraulic rod can drive the upper traction seat or the lower traction seat to move closer or farther away from each other through the T-shaped slider. Therefore, the distance between the upper traction seats and the lower traction seats on both sides is adjusted according to the width of the items. Then the items are placed on the traction wheel on one side of the lower frame, and the upper and lower positions of the upper frame are adjusted by the extension and contraction of the vertical hydraulic rod, so that the upper frame can also drive the upper traction seat to move up and down, so that the traction wheel on the side of the upper traction seat can press the items from the upper side.

Therefore, when the traction wheels on the upper and lower sides rotate in opposite directions, the objects between them can be transported. Because the three sets of racks are equidistantly arranged on the driving gear disc, when the driving gear disc rotates, it can intermittently engage with the driven gear disc, and when the driving gear disc drives the driven gear disc to rotate, the angle of rotation of the driven gear disc each time can be the same. Therefore, the angle of rotation of the traction wheel driven by the driven gear disc through the linkage shaft is also the same each time, so the objects can be accurately transported through the traction wheel.

[0029] The bottom surface of the upper traction seat 11 and the upper side surface of the lower traction seat 12 are fixed with a roller bracket 13 by bolts. A linkage shaft 14 rotates inside the roller bracket 13. A driven gear plate 15 is fixed to the end surface of the linkage shaft 14. A traction wheel 16 is fixed on the linkage shaft 14. A traction seat cavity 17 is opened inside the upper traction seat 11 and the lower traction seat 12. A traction hydraulic rod 18 is installed inside the traction seat cavity 17. A limited slide groove 19 is opened inside the limited slide groove 19. A limited slider 2 is slidably moved inside the limited slide groove 19. 0, the interior of the traction seat cavity 17 is rotatably connected to a driving gear disc 21 through a rotating pin, a rack 22 is fixed on the driving gear disc 21, a curved disc 23 is fixed on the end face of the driving gear disc 21, and a push-pull traction rod 24 is rotatably connected to the curved disc 23 through a rotating pin. The lower frame 2 can be fixedly connected to the external hydraulic stepping traction device through the lower fixed ear 6. When it is necessary to transport items, the vertical hydraulic rod 7 is started to drive the upper traction seat 11 and the lower traction seat 12 to move closer to each other, so that the traction wheels 16 on the upper and lower sides clamp the items first.

[0030] Furthermore, the curved plate 23 is concentric with the driving sprocket 21, and the push-pull traction rod 24 is rotatably connected to a non-center position of the curved plate 23 through a rotating pin, so that when the push-pull traction rod 24 moves, it can drive the driving sprocket 21 to rotate through the curved plate 23, so that the driving sprocket 21 can drive the driven sprocket 15 to rotate through the rack 22.

[0031] Furthermore, three groups of racks 22 are equidistantly arranged on the driving sprocket 21, and the number of racks 22 in each group is five. The driving sprocket 21 is engaged with the driven sprocket 15 through the racks 22, so that the driving sprocket 21 can drive the driven sprocket 15 to rotate through the racks 22. When the racks 22 are disengaged from the driven sprocket 15, the driven sprocket 15 remains stationary.

[0032] Furthermore, the limit slider 20 is fixedly connected to the traction hydraulic rod 18, and the end of the push-pull traction rod 24 away from the curved plate 23 is rotatably connected to the limit slider 20 through a rotating pin, so that when the traction hydraulic rod 18 drives the limit slider 20 to move, the limit slider 20 can drive the curved plate 23 to rotate by pushing and pulling the traction rod 24, and then the curved plate 23 can drive the driving gear plate 21 to rotate.

[0033] Furthermore, the upper traction seat 11 is slidably connected to the upper frame 1 through the upper T-shaped slot 8 and T-shaped slider 10, and the lower traction seat 12 is slidably connected to the lower frame 2 through the lower T-shaped slot 8 and T-shaped slider 10, so that the upper traction seat 11 can be guided by the upper T-shaped slot 8 and T-shaped slider 10, and the lower traction seat 12 can be guided by the lower T-shaped slot 8 and T-shaped slider 10.

[0034] Furthermore, the transverse hydraulic rod 9 is located inside the T-shaped slide 8, and the two ends of the transverse hydraulic rod 9 are fixedly connected to the T-shaped sliders 10 on both sides thereof. When the transverse hydraulic rod 9 is extended or contracted, the T-shaped sliders 10 on both sides can be driven to move closer to or away from each other, thereby driving the distance between the upper traction seat 11 or the lower traction seat 12 through the T-shaped sliders 10, so as to adjust the distance between the upper traction seat 11 or the lower traction seat 12.

[0035] Furthermore, the upper traction seat 11 and the lower traction seat 12 are symmetrically arranged, and the bottom surface of the upper traction seat 11 and the upper side surface of the lower traction seat 12 are provided with a roller bracket 13 and a traction wheel 16. When the upper traction seat 11 and the lower traction seat 12 are close to each other, the traction wheels 16 on the upper and lower sides also approach each other, and the objects can be clamped first by the traction wheels 16 on the upper and lower sides.

[0036] Furthermore, the upper frame 1 and the lower frame 2 are symmetrically arranged, and the upper frame 1 and the lower frame 2 are connected by a vertical hydraulic rod 7. When the vertical hydraulic rod 7 contracts, the upper frame 1 and the lower frame 2 can be brought closer, and then the upper traction seat 11 and the lower traction seat 12 can be brought closer, so as to subsequently clamp the items.

[0037] Furthermore, a driving gear disc 21 is provided inside the two sets of roller brackets 13, and a curved disc 23 is fixed on the inner end surface of the driving gear disc 21. A push-pull traction rod 24 is rotated between the curved discs 23 on both sides through a rotating pin, as shown in the attached figure of the specification. Figure 5 And the instruction manual Figure 6As shown, when the traction hydraulic rod 18 on the left is extended and the traction hydraulic rod 18 on the right is contracted, the traction hydraulic rod 18 on the left can enable the push-pull traction rod 24 to push the drive sprocket 21 from above to rotate clockwise, and the traction hydraulic rod 18 on the right can enable the push-pull traction rod 24 to push the drive sprocket 21 from below to rotate clockwise. At this time, the push-pull traction rod 24 on the right can rotate between the two sets of drive sprockets 21 without interfering with the drive sprocket 21 during the rotation process. Therefore, when the push-pull traction rods 24 on the left and right sides are in a horizontal position, they can also drive the drive sprocket 21 to rotate.

[0038] When in use, the lower frame 2 can be fixedly connected to the external hydraulic stepping traction device through the lower fixed ear 6. When it is necessary to transport items, the horizontal hydraulic rod 9 is started to drive the T-shaped sliders 10 on both sides to move closer or farther away from each other in the T-shaped slide 8, and then the T-shaped slider 10 can drive the upper traction seat 11 or the lower traction seat 12 to move closer or farther away from each other. Therefore, the distance between the upper traction seat 11 and the lower traction seat 12 on both sides is adjusted according to the width of the items, and then the items are placed on the traction wheel 16 on one side of the lower frame 2, and the upper frame is adjusted by the extension and contraction of the vertical hydraulic rod 7. The upper and lower positions of the frame 1 enable the upper frame 1 to also drive the upper traction seat 11 to move up and down, so that the traction wheel 16 on one side of the upper traction seat 11 can press the object from the upper side, so that the object to be transported can be placed between the upper and lower traction wheels 16, and the upper and lower traction wheels 16 can clamp and fix the object so that the object can be accurately transported later. When it is necessary to transport the object, the traction hydraulic rod 18 is started to reciprocate and extend or retract, and then the traction hydraulic rod 18 can drive the limit slider 20 to reciprocate horizontally inside the limit slide 19. At this time, The limiting slider 20 can drive the curved plate 23 to rotate by pushing and pulling the traction rod 24, and then the curved plate 23 can drive the driving gear plate 21 to rotate. When the rack 22 on the driving gear plate 21 is engaged with the driven gear plate 15, it can drive the driven gear plate 15 to rotate, and then the driven gear plate 15 can drive the traction wheel 16 to rotate through the linkage shaft 14. Therefore, when the traction wheels 16 on the upper and lower sides rotate in opposite directions, the objects between them can be transported. Similarly, when the rack 22 on the driving gear plate 21 is disengaged from the driven gear plate 15, the driven gear plate 15 remains stationary and the objects are clamped in The traction wheels 16 on the upper and lower sides also remain stationary because the three groups of racks 22 are equidistantly arranged on the driving gear disc 21, and the number of racks 22 in each group is the same. Therefore, when the driving gear disc 21 rotates, it can intermittently engage with the driven gear disc 15, and when the driving gear disc 21 drives the driven gear disc 15 to rotate, the angle of rotation of the driven gear disc 15 each time is the same. Therefore, the driven gear disc 15 drives the traction wheel 16 to rotate each time through the linkage shaft 14. Therefore, the objects can be accurately transported through the traction wheel 16, so as to improve the use effect of the hydraulic stepping traction device.
