DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4In an embodiment of the utility model, an automatic steel coil transfer device that is easy to adjust includes a base plate 1, a moving wheel 2 is installed at the bottom of the base plate 1, a handle 3 is welded on one side of the base plate 1 for moving the automatic steel coil transfer device that is easy to adjust, and a placement table 4 for placing steel coils is connected to the top of the base plate 1 through a shock absorbing mechanism.

[0023] The shock absorbing mechanism includes a support block 51, a first shock absorbing spring 52, a fixing rod 53, a slider 54, a second shock absorbing spring 55 and a connecting rod 56. Three groups of support blocks 51 are symmetrically welded on the top of the bottom plate 1. The first shock absorbing spring 52 is welded on the top of the support block 51. The other end of the first shock absorbing spring 52 is welded to the bottom of the placement table 4. Both sides of one group of support blocks 51 are welded with fixing rods 53. The other ends of the fixing rods 53 are respectively welded to one side of the other two groups of support blocks 51. The surface of the fixing rod 53 is symmetrically slidably connected with the slider 54. The side wall of the slider 54 close to the support block 51 is welded with a sleeve A second shock-absorbing spring 55 is arranged on the surface of the fixing rod 53, and the other end of the second shock-absorbing spring 55 is welded to the side of the support block 51. The top of the slider 54 is hingedly connected with a connecting rod 56, and the bottom of the placement table 4 is welded with a fixing block 57 located above the connecting rod 56. One end of the connecting rod 56 away from the slider 54 is hingedly connected to the two sides of the fixing block 57 respectively. A telescopic rod 9 that passes through the first shock-absorbing spring 52 is fixedly installed on the top of the support block 51. The top surfaces of the movable ends of the telescopic rod 9 are installed on the bottom of the placement table 4 by bolts. The telescopic rod 9 is provided to prevent the first shock-absorbing spring 52 from lateral deformation.

[0024] When vibration occurs during the transportation process, the placing table 4 is subjected to force to squeeze the first shock-absorbing spring 52 and the telescopic rod 9, causing the first shock-absorbing spring 52 and the telescopic rod 9 to be compressed and deformed, thereby buffering and absorbing the generated vibration. While being subjected to force, the placing table 4 drives one end of the connecting rod 56 hingedly connected to the fixed block 57 to move downward. At this time, the other end of the connecting rod 56 causes the slider 54 to slide away from each other on the surface of the fixed rod 53. When the fixed rod 53 slides, the second shock-absorbing spring 55 is squeezed, thereby further buffering and absorbing the generated vibration. Through multi-stage shock absorption, the stability of the steel coil during transportation is guaranteed.

[0025] A fixing mechanism for fixing the steel coil is symmetrically arranged on the top of the placing table 4, and the fixing mechanism includes a fixing plate 61, a first motor 62, a connecting plate 63, a threaded rod 64 and a resistance assembly. A rectangular groove 10 is symmetrically opened on the top of the placing table 4, and the bottom end of the fixing plate 61 is slidably connected inside the rectangular groove 10. The first motor 62 is installed on the top of the side of the fixing plate 61 through bolts. The connecting plate 63 is welded on the side of the fixing plate 61 away from the first motor 62. The output end of the first motor 62 is fixedly connected to the threaded rod 64 through a rotating shaft. The other end of the threaded rod 64 passes through the fixing plate 61 and the connecting plate 63 and is welded with a stopper 11 The threaded rod 64, the fixed plate 61 and the connecting plate 63 are all connected by threaded rotation. The surface of the threaded rod 64 is connected to a resistance assembly, which includes a sleeve 65, a resistance rod 66, a support rod 67 and a resistance wheel 68. The surface of the threaded rod 64 is connected to the sleeve 65 by threaded rotation. The side end of the connecting plate 63 close to the sleeve 65 is hingedly connected to the resistance rod 66. The middle parts of both sides of the resistance rod 66 are connected to the support rod 67 by bearings. The other ends of the support rods 67 are hingedly connected to the side walls of the sleeve 65. The ends of the resistance rods 66 away from the connecting plate 63 are connected to the resistance wheels 68 by bearings.

[0026] Four groups of abutment rods 66 are provided and distributed in a circular shape on the side of the connecting plate 63, so as to improve the stability of the abutment wheel 68 when abutting and fixing the inner wall of the steel coil.

[0027] When in use, the first motor 62 is started according to the size of the inner ring of the transported steel coil. When the output end of the first motor 62 rotates, the threaded rod 64 is driven to rotate accordingly, so that the sleeve 65 moves horizontally on its surface toward the side away from the connecting disk 63 or close to the connecting disk 63. When the sleeve 65 moves toward the side away from the connecting disk 63, one end of the support rod 67 hingedly connected to its side wall moves in the same direction. At this time, the other end of the support rod 67 drives the resistance wheel 68 to move toward the surface close to the threaded rod 64 through the resistance rod 66, and at the same time, the resistance The other end of the contact rod 66 rotates and moves on the side of the connecting disk 63, and the continuous movement of the sleeve 65 causes the diameter size between the contact wheels 68 to become smaller. When the sleeve 65 moves toward the side close to the connecting disk 63, the support rod 67 is used to make the contact rod 66 drive the contact wheel 68 to move toward the surface away from the threaded rod 64, thereby increasing the diameter size between the contact wheels 68. As a result, the steel coil automatic transfer device that is easy to adjust can fix and clamp steel coils with different inner ring sizes within the adjustment range, and the operation is simple and convenient to use.

[0028] The bottom end of the fixed plate 61 is connected to an adjustment mechanism located inside the rectangular groove 10 for adjusting the distance therebetween, the adjustment mechanism includes a second motor 71, a bidirectional screw 72 and a round rod 73, a second motor 71 is fixedly installed on one end of the side of the placement table 4, the output end of the second motor 71 is fixedly connected to the bidirectional screw 72 through a rotating shaft, the other end of the bidirectional screw 72 passes through the rectangular groove 10 and the fixed plate 61 and is rotatably connected to the inner wall of another rectangular groove 10 through a bearing seat, one side of the bidirectional screw 72 is welded with a round rod 73 located inside the rectangular groove 10, the other end of the round rod 73 passes through the fixed plate 61 and the placement table 4 and is welded to the inner wall of another rectangular groove 10, the fixed plate 61 is rotationally connected to the bidirectional screw 72 through a thread and is slidably connected to the round rod 73.

[0029] When in use, the second motor 71 is started, and when the output end of the second motor 71 rotates, the bidirectional screw 72 is driven to rotate accordingly, so that the fixing plates 61 move closer to or away from each other in the rectangular groove 10, and when the fixing plates 61 move, their bottom ends slide on the surface of the round rods 73, and the round rods 73 are used to provide stable support for their movement. When the fixing plates 61 move closer to or away from each other, the connecting disk 63 can be used to drive the fixing mechanism to move synchronously with it, so that the fixing mechanism can fix and clamp steel coils of different lengths, thereby improving the practicality of the easy-to-adjust steel coil automatic transfer device.

[0030] One side of the connecting plate 63 is provided with a lifting mechanism located on the top of the placement table 4 for assisting in lifting the steel coil. The lifting mechanism includes a hydraulic push rod 81 and a lifting plate 82. One side of the connecting plate 63 is provided with a hydraulic push rod 81 located on the top of the placement table 4 by bolts, and a lifting plate 82 is fixedly installed on the top surface of the movable end of the hydraulic push rod 81. When in use, the hydraulic push rod 81 is started to extend its movable end, thereby driving the lifting plate 82 to move toward the bottom surface of the steel coil, so that the lifting plate 82 can support the steel coil and make it stably fixed on the top of the placement table 4.

[0031] Working principle: When the easy-to-adjust steel coil automatic transfer device is to be used, first start the hydraulic push rod 81 to drive the lifting plate 82 to a suitable lifting position, then place the steel coils on the top of the lifting plate 82 in turn, and then start the second motor 71 to control the operation of the adjustment mechanism, so that the bidirectional screw 72 drives the fixed plate 61 to move closer to each other, and when the fixed plate 61 moves, it drives the resistance assembly to move toward the two ends of the steel ring. When the resistance assembly moves to the inside of the two ends of the steel ring, start the first motor 62 to control the resistance assembly to operate through the threaded rod 64, so that the resistance wheel 68 contacts the inner wall of the steel ring, and then the steel ring is fixed by resistance, so that it will not be moved during the transportation process. When the steel ring is fixed, the handle 3 and the moving wheel 2 are used to cooperate to move the steel coil automatic transfer device which is easy to adjust. When vibration occurs during the transfer process, the placing table 4 is subjected to force to squeeze the first shock-absorbing spring 52 and the telescopic rod 9, so that the vibration generated is buffered and absorbed by the action of the first shock-absorbing spring 52, and at the same time, one end of the connecting rod 56 is moved downward through the fixed block 57. At this time, the other end of the connecting rod 56 makes the slider 54 slide away from each other on the surface of the fixed rod 53, thereby squeezing the second shock-absorbing spring 55, and further buffering and absorbing the vibration generated, thereby ensuring the stability of the steel coil during transfer.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
