Description

Technical Field

[0001] This invention is a divisional application of "A Disassembly Vehicle for Cold-Rolled Strip Coiling Sleeves" (application number: 201910253803.0) (application date: 2019-03-30), and relates to an auxiliary tool for steel manufacturing, particularly a tool suitable for replacing rubber sleeves on a cold-rolled production line coiler. Background Technology

[0002] Drum-type cold strip coilers are commonly used equipment in steel production. They mainly consist of an expanding and contracting drum and a transmission device. The drum is also equipped with a belt winding aid or jaws. The drum can expand and contract under high pressure to provide winding tension. A rubber sleeve is fitted on the drum, and the steel coil is directly wound onto the rubber sleeve. Depending on customer needs, the coiler is often used to wind steel coils of different inner diameters, in which case the rubber sleeve needs to be replaced.

[0003] Existing sleeve replacement operations mostly employ methods such as overhead crane transport, installation of auxiliary pallets on the steel coil trolley, and manual assistance. The outward movement of the sleeve via crane and trolley movement, coupled with variations in the distance between the coiler core shaft and the ground, and changes in the sleeve's specifications, creates positioning difficulties and lengthy replacement times. Because the inner and outer walls of the sleeve are coated with anti-rust oil, they are very smooth. Since there is no fixed point between the trolley and the sleeve, the sleeve's loading and unloading relies entirely on slight friction between its outer surface and the trolley, requiring manual assistance throughout the process for sleeve positioning. This leads to worker fatigue and poses significant safety risks. Furthermore, during installation, the sleeve's diameter may be too close to the coiler core, making end assembly difficult and time-consuming. Careless operation can also damage the edges of the rubber sleeve. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. For ease of description, [the following is used...] Figure 1 To determine left and right, use the left and right sides as the reference.

[0023] like Figures 1-5 As shown, Embodiment 1 of the present invention includes a vehicle body 2, a lifting plate 9, a support pipe 14, a support plate 18, a first lifting device, a second lifting device, and a sleeve support device.

[0024] The first lifting device is installed inside the vehicle body 2. The first lifting device includes a first lead screw 8, a first lead screw nut 7, a first connecting plate 4, and a second connecting plate 5. Two first guide plates 6 are respectively provided on both sides of the lifting plate 9. The first guide plate 6 is provided with an elongated guide hole. The two side walls of the vehicle body 2 are respectively provided with elongated guide holes. The upper end of the second connecting plate 4 is hinged to the first guide plate 6, and the lower end is provided with a first guide shaft. The first guide shaft passes through the elongated guide hole on the side wall of the vehicle body 2 and is connected to the positioning plate.

[0025] A through hole is provided on the left wall of the vehicle body 2. The right end of the first lead screw 8 is rotatably connected to the right wall of the vehicle body 2, and the left end passes through the through hole on the left wall of the vehicle body 2 and is connected to the first rocker arm 1. The lower ends of the two second connecting plates 5 are respectively hinged to the first lead screw nut 7, and the upper ends are connected to the second guide shaft. The second guide shaft passes through the elongated guide hole on the first guide plate 6 and is connected to the positioning plate. The first connecting plate 4 and the second connecting plate 5 are hinged at the middle position. The first lead screw 8 and the first lead screw nut 7 cooperate with each other. When the first rocker arm 1 is rotated, the first rocker arm 1 drives the first lead screw 8, the first lead screw nut 7, the first connecting plate 4 and the second connecting plate 5 to move in sequence, thereby realizing the lifting plate 9 lifting up and down.

[0026] The left end of the first lead screw 8 is provided with an annular groove. A section of the outer wall of the annular groove of the first lead screw 8 is provided with a slider. One end of the first rocker arm 1 has a through hole, and the through hole of the first rocker arm 1 fits onto the annular groove of the first lead screw 8. The inner wall of the through hole of the first rocker arm 1 is provided with a sliding groove. When rotation is required, the sliding groove of the first rocker arm 1 is fitted onto the slider. After rotation, the first rocker arm 1 is pulled to the section of the annular groove without the slider, thereby preventing the first rocker arm 1 from driving the first lead screw 8 to rotate due to gravity. The connection method of other rockers and lead screws is the same as described above.

[0027] The upper left end of the vehicle body 2 has a hollow support tube 14, and the support plate 18 is inserted into the cavity of the support tube 14. The support tube 14 and the support plate 18 are connected by a second lifting device.

[0028] The second lifting device includes a first screw 29, a second guide rod 24, a driving bevel gear 30, and a driven bevel gear 31. The lower end of the first screw 29 is rotatably connected to the bottom wall of the cavity of the support tube 14. The second guide rod 24 is fixedly connected to the bottom wall of the cavity of the support tube 14. The lower end of the first screw 29 is fixedly connected to the gear hole of the driven bevel gear 31. A through hole is provided on the side wall of the support tube 14. One end of the rotating shaft passes through the through hole on the support tube 14 and is connected to the driving bevel gear 30. The other end is connected to the second rocker arm 13. The driving bevel gear 30 and the driven bevel gear 31 mesh with each other.

[0029] The lower end of the support plate 18 is provided with a threaded blind hole and a guide blind hole. The first screw 29 is threadedly connected to the threaded blind hole of the support plate 18, and the second guide rod 24 is inserted into the guide blind hole of the support plate 18. When the second rocker arm 13 is rotated, the second rocker arm 13 sequentially drives the driving bevel gear 30, the driven bevel gear 31, and the first screw 29 to rotate, thereby driving the second support plate 18 to move up and down along the second guide rod 24.

[0030] The lifting plate 9 has multiple parallel sliding grooves. A second lead screw 32 is installed in the middle groove, and third guide rods 33 are installed in the other grooves. A through hole is provided on the left wall of the middle groove. One end of the second lead screw 32 is rotatably connected to the wall of one end of the middle groove, and the other end passes through the through hole on the other end wall and is connected to the third rocker arm 12. Both ends of the third guide rod 33 are fixedly connected to the walls of both ends of the groove. The lower end of the first push plate 20 has a second lead screw nut 46 and a guide block. The guide block has a guide through hole. The second lead screw 32 is threadedly connected to the second lead screw nut 46, and the third guide rod 33 passes through the guide through hole of the guide block. The first push plate 20 has a through hole.

[0031] When the first push plate 20 needs to be reset, rotating the second lead screw 32 can only cause the first push plate 20 to move slowly. Therefore, when it is necessary to quickly push the first push plate 20, the second lead screw nut 46 needs to be divided into two parts to achieve this linkage separation. Figure 6 , 7 As shown, the lower end of the first push plate 20 is connected to the third guide cylinder 47. The cavity of the third guide cylinder 47 contains two semi-lead screw nuts 50, which can be combined to form a complete lead screw nut. Each of the semi-lead screw nuts 50 has a third ear plate 55 at both ends, and the third ear plate 55 has a guide hole. Each of the two ends of the cavity of the third guide cylinder 47 has a fifth guide rod 48, and both ends of the fifth guide rod 48 are connected to the side wall of the cavity of the third guide cylinder 47. A third compression spring 49 is sleeved on the outside of the fifth guide rod 48. One end of the third compression spring 49 rests against the third ear plate 55 of the semi-lead screw nut 50, and the other end rests against the inner wall of the cavity of the third guide cylinder 47. The upper end of the third guide cylinder 47 is provided with a positioning through hole, and both ends of the positioning through hole are provided with guide through holes. The upper end of the half-screw nut 50 is provided with a groove, and the lower end of the groove is provided with an inclined surface. The lower end of the positioning rod 54 passes through the positioning through hole on the third guide cylinder 47 and is located above the half-screw nut 50. The upper end of the positioning rod 54 is provided with a shoulder. The outer end of the half-screw nut 50 is provided with a top shaft 51. The lower end of the top rod 52 has an inclined surface, passes through the guide through hole on the third guide cylinder 47, and abuts against the outer end of the top shaft 51. The upper ends of the two top shafts 51 are connected by a connecting rod 53. The upper end of the third guide cylinder 47 is hinged to the middle position of the pressure plate 56. The hinge method is as follows: the upper end of the third guide cylinder 47 is provided with two fourth ear plates, and the fourth ear plates are hinged to the middle position of the pressure plate 56. One end of the pressure plate 56 has a slot, through which the positioning rod 54 passes. The shoulder of the positioning rod 54 presses against the pressure plate 56, and the other end of the pressure plate 56 is placed at the lower end of the connecting rod 53. When the positioning rod 54 is pressed down, it drives the connecting rod 53 and the top rod 52 to rise sequentially through the pressure plate 56, moving them away from the top shaft 51 of the half-screw nut 50. During the downward pressing process, the positioning rod 54 inserts into the slots of the two half-screw nuts 50, separating them and clamping the positioning rod 54 between them. When released, it returns to its original position by spring, and the two half-screw nuts 50 combine to form a complete screw nut.

[0032] The support plate 18 and the sleeve support device are detachably connected. The sleeve support device includes an outer sleeve 19, a second screw 17, and a fixed sleeve 23. The fixed sleeve 23 has a cavity with one end open, and the inner side wall of the fixed sleeve 23 has a plurality of threaded through holes arranged in a uniform circular shape.

[0033] The inner wall of the outer sleeve 19 has threads adapted to the second screw 17, which passes through the outer sleeve 19 and connects to the fixed sleeve 23. Multiple mushroom-shaped threaded support rods 3 are screwed into the threaded through holes on the side wall of the fixed sleeve 23. The arc-shaped tops of the threaded support rods 3 provide support and fixation for the rubber sleeve.

[0034] The left end of the outer sleeve 19 is provided with an external thread, and the support plate 18 is provided with a threaded through hole. The left side of the outer sleeve 19 passes through the through hole of the first push plate 20 and is threadedly connected to the threaded through hole of the support plate 18. The left end of the second screw 17 is connected to the rotating disk 16. The side of the rotating disk 16 is provided with multiple threaded blind holes. One end of the handle rod 15 is provided with an external thread, and the handle rod 15 is threadedly connected to the threaded blind hole of the rotating disk 16. By rotating the second screw 17, the fixed cylinder 23 can be pushed forward; by pre-adjusting the threaded support rod 3, it can accommodate rubber sleeves of different diameters.

[0035] The lower end of the vehicle body 2 is provided with multiple casters 11 equipped with foot brakes. The first push plate 20 is connected to the horizontal plate of the L-shaped plate 10, and the vertical plate of the L-shaped plate 10 is provided with a through hole, through which the outer sleeve 19 passes.

[0036] The operating procedure is as follows: When not in use, remove the sleeve support device from the support plate 18. When in use, reinstall the sleeve support device on the support plate 18, place the right end of the rubber sleeve onto the sleeve support device, adjust the first push plate 20 to press against the left end of the rubber sleeve, and adjust the position of the threaded support rod 3 to adapt to the diameter of the rubber sleeve, ensuring the left end of the rubber sleeve is in the correct position. Adjust the second lifting device to place the rubber sleeve on the lifting plate 9, adjust the first lifting device to align the rubber sleeve with the shaft of the winding machine, push the carriage 2 so that the shaft is inserted a short distance into the sleeve support of the rubber sleeve, rotate the second screw 17 to move the fixed cylinder 23 to the left, causing the sleeve support device to move away from the shaft. At the same time, rotate the second lead screw 32 to move the first push plate 20 to the right, slowly pushing the rubber sleeve into the outside of the shaft, thus preventing excessive force from breaking the rubber sleeve.

[0037] In Example 1, the first push plate 20 has a fixed through-hole size. Therefore, for rubber sleeves of different diameters, the first push plate 20 needs to be replaced with one having a different through-hole size. For example... Figure 7 , 8As shown, Embodiment 2 improves upon Embodiment 1 by modifying the push plate: the first push plate 20 in Embodiment 1 is replaced with a second push plate 41. The second push plate 41 has a lower height and a cavity. A through hole is located on one end of the wall of the second push plate 41, and a slide hole is located on the right end of the second push plate 41, communicating with the cavity. One end of a bidirectional lead screw 45 is rotatably connected to the inner wall of one end of the second push plate 41, and the other end passes through the through hole of the second push plate 41 and connects to a rotating handle 40. The threads on both ends of the bidirectional lead screw 45 are respectively connected to a third lead screw nut 44, which is connected to one end of a third connecting plate 42. The other end of the third connecting plate 42 passes through the slide hole on the second push plate 41 and connects to a clamping plate 43. In use, the second push plate 41 is placed against the left end of the rubber sleeve, and the bidirectional lead screw 45 is rotated, causing the two clamping plates 43 to clamp the outer wall of the rubber sleeve.

[0038] The upper end of the second push plate 41 is connected to the support plate 34. The support plate 34 is provided with a through hole. The outer sleeve 19 passes through the through hole of the support plate 34, thereby providing a certain support for the outer sleeve 19.

[0039] Example 3 improves upon Example 2 by enlarging the port of the rubber sleeve, thus accelerating the docking process. For example... Figure 9 and 10 As shown, the sleeve support device in Embodiment 3 includes an outer sleeve 19, a second screw 17, a fixed sleeve 23, a fourth guide rod 28, and a cone 25. The fixed sleeve 23 has a cavity with one end open. Multiple second guide sleeves are arranged in a uniform circular pattern on the inner wall of the fixed sleeve 23. The second guide sleeves are provided with guide through holes. The left end of the fixed sleeve 23 is provided with a guide sleeve 22. The guide sleeve 22 is provided with a guide through hole that communicates with the cavity of the fixed sleeve 23.

[0040] The outer sleeve 19 has a stepped through hole, the small diameter of which is a threaded hole. The guide sleeve 22 is inserted into the large diameter hole of the stepped through hole, and the guide sleeve 22 is connected to the bottom of the large diameter hole by a first compression spring 21. The second screw 17 passes through the stepped through hole of the outer sleeve 19 and the guide through hole of the guide sleeve 22 and is connected to the truncated cone 25. The truncated cone 25 is placed in the cavity of the fixed cylinder 23. The inner end of the fourth guide rod 28 passes through the guide through hole of the second guide cylinder and rests on the outer wall of the truncated cone 25, and the outer end is connected to the arc-shaped support plate 27. The fourth guide rod 28 is provided with a collar, and a second compression spring 26 is installed between the collar and the second guide cylinder.

[0041] The operating procedure is as follows: When not using this device, remove the sleeve support device from the second support plate 18. When using it, reinstall the sleeve support device on the second support plate 18, place the right end of the rubber sleeve onto the sleeve support device, adjust the first push plate 20 to press against the left end of the rubber sleeve, and rotate the second screw 17 to move the cone 25 to the right, increasing the distance of the fourth guide rod 28 protruding from the fixed cylinder 23, thus widening the right end of the rubber sleeve. Adjust the second lifting device to position the rubber sleeve in the lifting position. On plate 9, adjust the first lifting device to align the rubber sleeve with the shaft of the winding machine, push the carriage 2 so that the shaft is inserted a short distance into the rubber sleeve support, rotate the second screw 17 to move the cone 25 to the left, reducing the distance the fourth guide rod 28 protrudes from the fixed cylinder 23. When the cone 25 reaches the inner wall of the left end of the fixed cylinder 23, continue rotating the second screw 17. The second screw 17 drives the fixed cylinder 23 to move to the left, compressing the first compression spring 21 and causing the sleeve support device to move away from the shaft. At the same time, rotate the second lead screw 32 to move the first push plate 20 to the right, slowly pushing the rubber sleeve into the outer side of the shaft, thus preventing excessive force from breaking the rubber sleeve.

[0042] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes made to it without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
