Specific embodiments

[0022] The following will describe in detail the embodiments of the present application in conjunction with the accompanying drawings and examples, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0023] As Figures 1-5 shown, the special cart for shifting the drying cylinder provided in this embodiment includes two symmetrically arranged moving bases 1 with moving wheels. Connecting bases 3 are slidably arranged on both end faces of the two moving bases 1. T-shaped slide rails 9 are arranged at both ends of the moving base 1, and limiting plates 10 are arranged at both ends of the T-shaped slide rail 9. A slider 11 which is slidably connected to the T-shaped slide rail 9 and is provided with a T-shaped chute is arranged on the connecting base 3;

[0024] Furthermore, as Figure 1 , Figure 3 and Figure 5As shown, every two connecting bases 3 in the same direction are connected by a connecting plate 4. A traction block 5 is arranged on the outer side surface of the connecting plate 4. Mounting plates 22 are symmetrically arranged at the middle position of the outer end surface of the connecting plate 4. The traction block 5 includes a second connecting block 23 rotatably connected between the two mounting plates 22 and a pull rod 25 rotatably connected to the front end surface of the second connecting block 23 and having a traction hole 24. The rotation direction of the pull rod 25 intersects with the rotation direction of the second connecting block 23. The mutually intersecting rotation of the second connecting block 23 and the pull rod 25 can improve the flexibility of the traction block 5 when connecting with a hoist or other traction devices;

[0025] Furthermore, as Figure 1 and Figure 3 shown, a support rod 2 is arranged between the two connecting plates 4. Movable wheels are also arranged on the lower end surface of the support rod 2, which can improve the support of the connection structure between the two movable bases 1. The movable wheels are of a universal wheel structure. The setting of the universal wheel structure can improve the flexibility during its movement and will not affect the adjustment of the spatial distance between the two movable bases 1;

[0026] Further, as Figure 1 and Figure 3 shown, electric telescopic rods 6 are arranged on both sides of the support rod 2. The telescopic ends of the electric telescopic rods 6 on both sides are respectively connected to the inner sides of the two movable bases 1; when adjusting the distance between the two movable bases 1, by simultaneously extending or contracting the electric telescopic rods 6 on both sides, the two symmetric movable bases 1 are driven to move inwards or outwards simultaneously, so that two support frames 7 symmetrically arranged above the two movable bases 1 are adjusted preliminarily in position, so as to adapt to the placement of drying cylinders of different lengths and improve the adaptability during the use of the device;

[0027] Further, as Figure 1 、 Figure 2 and Figure 4 shown, support frames 7 for supporting the dryer shaft seats are slidably arranged on the upper end surfaces of the two movable bases 1. A chute 12 consistent with the running direction of the electric telescopic rod 6 is opened on the upper end surface of the movable base 1. A lead screw 13 is rotatably connected in the chute 12. One end of the lead screw 13 penetrates to the outside of the movable base 1, and a driving motor 14 connected to the lead screw 13 is fixedly arranged outside the movable base 1;

[0028] Furthermore, as Figure 1 、 Figure 2 and Figure 4As shown, a large-aperture placement groove 15 is provided at the upper end of the support frame 7, which can accommodate the placement of drying cylinder bearing seats of various diameters, and a second slider 16 is provided on the lower end surface of the support frame 7, which is slidably connected to the slide groove 12 and is threadedly connected to the screw rod 13; after the positions of the two movable bases 1 are preliminarily adjusted, if the placement distance requirement is still not met, the screw rod 13 is driven by the drive motor 14 to rotate in the second slider 16, so that the second slider 16 slides in the slide groove 12, thereby driving the upper support frame 7 to slide and adjust, wherein it should be noted that the two drive motors 14 can operate synchronously or separately;

[0029] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the support frame 7 is provided with a fixing mechanism 8 for fixing the position of the supporting cylinder shaft seat. There are two fixing mechanisms 8, which are symmetrically arranged on both sides of the upper end surface of the support frame 7. The fixing mechanism 8 includes a support block 17 arranged at the upper end of the support frame 7 and a threaded rod 18 threadedly screwed and connected to the support block 17. The outer side of the upper end surface of the support block 17 is a slope structure arranged from top to bottom and gradually outward. A threaded hole that penetrates the support block 17 and is threadedly screwed and connected to the threaded rod 18 is opened on the slope structure. After the drying cylinder bearing seat is placed in the large-aperture placement groove 15, the position of the threaded rod 18 is adjusted according to the diameter of the bearing seat to ensure that the threaded rod 18 can resist the position of the bearing seat and improve the stability of the drying cylinder during transportation. A rubber pad 20 is arranged at the inner end of the threaded rod 18. The arrangement of the rubber pad 20 can ensure that no scratches will occur when the drying cylinder bearing seat is fixed, and can also play an anti-slip effect. A rotating handle 21 is arranged at the outer end of the threaded rod 18. The rotating handle 21 facilitates the rotation of the threaded rod 18.
