Description

Technical Field

[0001] The utility model belongs to the hot rolling field of the steel metallurgical industry, and particularly relates to a slab conveying device. Background Art

[0002] In the hot-rolling sector of the iron and steel industry, most slabs are first hoisted onto roller tables using lifting equipment, and then transported and transferred via the roller tables. Furthermore, for subsequent processing, both wide and long slabs and narrow and short slabs must be aligned with the conveying direction of the roller tables. When conveying slabs, if both wide and long slabs and narrow and short slabs are to be transported, the width of the roller tables must accommodate the width of the wide and long slabs. Consequently, the narrow and short slabs have a significant excess width on the roller tables, reducing the storage capacity of the narrow and short slabs on the roller tables, affecting the lifting efficiency of the lifting equipment, and ultimately, production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a slab conveying device, which can improve the storage capacity of narrow and short slabs on the loading roller, improve the lifting efficiency of the lifting equipment, and thus improve the production efficiency.

[0004] The technical solution adopted in this utility model is:

[0005] A slab conveying device comprises a loading roller, a conveying roller perpendicular to the loading roller, a turning roller perpendicular to the loading roller and located between the loading roller and the conveying roller, and a steel pusher located on one side of the loading roller and used for pushing the slab to the turning roller; the working width of the loading roller is greater than the width of the wide and long slab and the length of the narrow and short slab, the working width of the conveying roller is greater than the width of the wide and long slab, and the working width of the turning roller is greater than the length of the wide and long slab; the turning roller is used to convey the slab to the conveying roller and to turn the wide and long slab, and two groups of staggered and independent tapered rollers are used along the line, and the tapers of the two groups of tapered rollers are the same and the directions are opposite.

[0006] Preferably, centering mechanisms for centering the wide and long slabs are provided on both sides of the turning roller.

[0007] Preferably, the centering mechanism includes a push plate for pushing the wide and long slab, a cylinder for driving the middle of the push plate, a guide rod for guiding both sides of the push plate, and a support for installing the cylinder.

[0008] Preferably, fixed baffles for limiting positioning are provided at both ends of the loading roller.

[0009] Preferably, a buffer pad is provided on the working surface of the fixed baffle.

[0010] Preferably, the steel pusher is arranged in the middle of the loading roller, and the loading roller transports from the end to the middle.

[0011] The beneficial effects of the utility model are:

[0012] During operation, the lifting equipment lifts the wide and long slabs and the narrow and short slabs onto the loading roller. The length direction of the wide and long slabs is in the same direction as the conveying direction of the loading roller, and the width direction of the narrow and short slabs is in the same direction as the conveying direction of the loading roller. Multiple narrow and short slabs are placed side by side, and then the loading roller works to drive the slabs to the pusher working position, and then the pusher pushes the slabs to the turning roller, and then the turning roller works. For wide and long slabs, the two sets of tapered rollers first rotate in opposite directions to drive the wide and long slabs to turn 90 degrees, and then the two sets of tapered rollers rotate in the same direction to drive the wide and long slabs into the conveying roller. After that, the length direction of the wide and long slabs is in the same direction as the conveying direction of the conveying roller and is conveyed by the conveyor roller. For narrow and short slabs, the two sets of tapered rollers rotate directly in the same direction to drive the narrow and short slabs into the conveying roller. After that, the length direction of the narrow and short slabs is in the same direction as the conveying direction of the conveyor roller and is conveyed by the conveyor roller. It can be seen that when loading, this device can make the width direction of the narrow and short slabs the same as the conveying direction of the loading roller and place multiple narrow and short slabs side by side, which can improve the storage capacity of the narrow and short slabs on the loading roller, improve the lifting efficiency of the lifting equipment, and thus improve production efficiency.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] The present application provides a slab conveying device, such as Figure 1 As shown, it includes a loading roller 3, a conveying roller 8, a turning roller 6 and a steel pusher 4; wherein:

[0017] The loading roller 3 has a working width greater than the width of the wide and long slab 2 and the length of the narrow and short slab 5. Figure 1 ;

[0018] The conveying roller 8 is perpendicular to the loading roller 3 and its working width is greater than the width of the long and wide slab 2. Figure 1 ;

[0019] The turning roller 6 is perpendicular to the loading roller 3 and is located between the loading roller 3 and the conveying roller 8. Its working width is greater than the length of the wide and long slab 2. It is used to convey the slab to the conveying roller 8 and to turn the wide and long slab 2. Two sets of staggered and independent tapered rollers are used along the line. The tapers of the two sets of tapered rollers are the same and in opposite directions. Figure 1 ;

[0020] The pusher 4 is located on one side of the loading roller 3 and is used to push the slab to the turning roller 6. Figure 1 .

[0021] While working:

[0022] The lifting equipment lifts the wide and long slab 2 and the narrow and short slab 5 onto the loading roller 3. The length direction of the wide and long slab 2 is in the same direction as the conveying direction of the loading roller 3, and the width direction of the narrow and short slab 5 is in the same direction as the conveying direction of the loading roller 3. Multiple narrow and short slabs 5 are placed side by side, and then the loading roller 3 works to drive the slabs to the working position of the pusher 4, and then the pusher 4 pushes the slabs to the turning roller 6, and then the turning roller 6 works. For the wide and long slab 2, the two sets of tapered rollers first rotate in opposite directions to drive the wide and long slab 2 to turn 90 degrees, and then the two sets of tapered rollers rotate in the same direction to drive the wide and long slab 2 into the conveying roller 8. After that, the length direction of the wide and long slab 2 is in the same direction as the conveying direction of the conveying roller 8 and is conveyed by the conveying roller 8. For the narrow and short slab 5, the two sets of tapered rollers rotate directly in the same direction to drive the narrow and short slab 5 into the conveying roller 8. After that, the length direction of the narrow and short slab 5 is in the same direction as the conveying direction of the conveying roller 8 and is conveyed by the conveying roller 8.

[0023] From the above basic scheme, we can know that:

[0024] When loading, this device can make the width direction of the narrow and short slabs 5 be in the same direction as the conveying direction of the loading roller 3 and multiple narrow and short slabs 5 can be placed side by side, which can improve the storage capacity of the narrow and short slabs 5 on the loading roller 3, improve the lifting efficiency of the lifting equipment, and thus improve production efficiency.

[0025] In the process of the two sets of tapered rollers rotating in opposite directions to drive the wide and long slab 2 to turn 90 degrees, the center of the wide and long slab 2 may be offset. If the offset is too large, it may interfere with the conveyor roller 8. In order to avoid this problem, Figure 1 As shown, in this embodiment: a centering mechanism 7 for centering the wide and long slab 2 is added on both sides of the turning roller 6. After the wide and long slab 2 enters the turning roller 6, the two sets of tapered rollers first rotate in the same direction, driving the wide and long slab 2 into the working position of the centering mechanism 7. Then the two sets of tapered rollers rotate in opposite directions to drive the wide and long slab 2 to turn 90 degrees. Then the centering mechanisms 7 on both sides extend synchronously to re-center the wide and long slab 2. Then the two sets of tapered rollers rotate in the same direction again, driving the wide and long slab 2 into the conveying roller 8. Figure 1As shown, in this embodiment, the centering mechanism 7 includes a push plate 71 for pushing the wide and long slab 2, a cylinder 74 for driving the middle of the push plate 71, a guide rod 72 for guiding both sides of the push plate 71, and a support 73 for installing the cylinder 74.

[0026] In order to avoid the slab from falling out, Figure 1 As shown, in this embodiment, fixed baffles 1 for limiting are provided at both ends of the feeding roller 3. In this embodiment, a buffer pad is provided on the working surface of the fixed baffle 1 to slow down the impact damage.

[0027] like Figure 1 As shown, in this embodiment, the pusher 4 is located in the middle of the loading roller 3, and the loading roller 3 transports the material from the end to the middle. The two ends of the loading roller 3 are used as the lifting area, and the wide and long slabs 2 and the narrow and short slabs 5 can be loaded at both ends, further improving the lifting efficiency.

The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
