[0002] In the hot rolling production line, after the coil is produced, it is necessary to inspect the surface, take samples, cut the outer ring defects, etc., which will leave a lot of scrap steel plates. These scrap steel plates need to be transported to other spans adjacent to the production line spans by span cars and transportation systems.

[0003] At present, straddle carriers and transport systems are generally only suitable for transporting regular objects, but scrap steel plates are irregular in shape, making it difficult to lift them onto straddle carriers and transport systems. In addition, many steel plates have a certain height, and when placed on straddle carriers and transport systems, they are prone to tipping over, posing an unsafe factor. At the same time, straddle carriers and transport systems with smaller specifications also find it difficult to transport larger scrap steel plates, affecting the operating efficiency of the production line.

[0038] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0039] Figure 1 A schematic diagram of the structure of a straddle carrier in some embodiments or certain embodiments of the present application is shown. Figure 2 Shows Figure 1 Side view of the mid-span vehicle, combined with Figure 1 and Figure 2 In some embodiments, a cross-cart provided in an embodiment of the present application is used for moving and transporting scrap steel plates 100, including:

[0040] The vehicle body 1 is provided with a platform 11 for placing the scrap steel plate 100 .

[0041] At least two extension components 2 surround the platform 11 and are connected to the platform 11 at intervals. The extension components 2 extend from the platform 11 to protrude from the platform 11 to increase the space for placing the scrap steel plate 100.

[0042] At least two limiting components 3 are respectively connected to two sides of the platform 11 and staggered with the extension component 2 so as to limit the scrap steel plate 100 between the at least two limiting components 3 .

[0043] The body 1 of the cross-carriage is provided with a platform 11, which can be used to place the scrap steel plate 100. The extension component 2 surrounding the platform 11 and connected to the platform 11 at intervals extends from the platform 11 to protrude from the platform 11. On the basis of the space provided by the platform 11, the extension component 2 can provide additional placement space for the scrap steel plate 100, so that the cross-carriage with smaller specifications can also transport the scrap steel plate 100 with larger size, thereby improving the versatility of the cross-carriage. The extension component 2 is arranged around the platform 11, which can make the overall center of gravity of the cross-carriage relatively stable during the transportation of the scrap steel plate 100, reduce the possibility of the cross-carriage tipping over, and improve the safety factor of the cross-carriage. The limiting component 3 is staggered with the extension component 2 and is located on both sides of the platform 11, so that the scrap steel plate 100 can be limited between the limiting components 3 on both sides of the two platforms 11, and the scrap steel plate 100 can be placed on the platform 11 as much as possible, reducing the possibility of the scrap steel plate 100 falling from the platform 11, which is conducive to improving the safety factor of the cross-carriage in transporting the scrap steel plate 100. The improvement of the safety factor and the improvement of the efficiency of transferring the scrap steel plate 100 to the steel plate 100 are both beneficial to improving the operating efficiency of the production line.

[0044] Moreover, this type of cross-carriage can increase the number of scrap steel plates 100 that the cross-carriage can transport at one time without increasing the specifications and dimensions of the vehicle body 1 itself, thereby reducing the safety problems caused by excessive accumulation of scrap steel plates 100, and can also improve work efficiency and safety factor. For different types of cross-carriages, if the cross-carriage is smaller and needs to transport steel plates 100 as long as 5 meters or 6 meters, the extension component 2 extending and protruding relative to the platform 11 can place the portion of the steel plate 100 that is longer than the platform 11 or the vehicle body 1; therefore, a smaller cross-carriage is used to reduce equipment costs.

[0045] In some embodiments, the platform 11 is a rectangular platform 11 , at least two extension components 2 are respectively located at two ends of the platform 11 in the length direction, and at least two limit components 3 are respectively located at two sides of the platform 11 in the width direction.

[0046] The platform 11 is a rectangular platform 11, and the two ends of the platform 11 in the length direction and the two sides in the width direction are respectively connected to the extension component 2 and the limit component 3. The center of gravity of the entire straddle carrier is relatively stable, and usually the maximum length that the scrap steel plate 100 can reach is much greater than the maximum width that the scrap steel plate 100 can reach. Therefore, the extension components 2 are arranged at both ends of the length direction of the platform 11. When the specifications of the vehicle body 1 itself are relatively small, the versatility of the entire straddle carrier and the overall preparation cost can be effectively improved.

[0047] In some embodiments, platform 11 includes:

[0048] The platform body 111 and at least two support members 112 connected to the platform body 111 at intervals and higher than the platform body 111 .

[0049] The platform body 111 can be used as the main supporting structure. At least two supporting members 112 higher than the platform body 111 are arranged on the platform body 111. The scrap steel plates 100 can be supported on the supporting members 112, and there is a gap between the scrap steel plates 100 supported on the supporting members 112 and the platform body 111. These gaps can facilitate the disassembly and assembly of some things, such as ropes or wire ropes that encircle the scrap steel plates 100, which is beneficial to improving the transportation efficiency of the scrap steel plates 100.

[0050] In some embodiments, the platform body 111 may be rectangular, the support member 112 may be block-shaped or plate-shaped, and may be provided in two pieces, the two support members 112 may be provided on the platform body 111 at intervals along the length direction of the platform body 111, and the length direction of the support member 112 may extend along the width direction of the platform body 111. It is easy to prepare and the center of gravity is relatively stable.

[0051] In some embodiments provided in the present application, the platform body 111 may also be configured to be circular or square in shape, etc. The present application does not impose any limitation on this.

[0052] In some embodiments, the support member 112 is welded and fixed to the platform body 111, and the support member 112 is an I-beam or a support block, which is convenient for preparation and reduces the preparation cost of the straddle carrier.

[0053] In some embodiments, the extension assembly 2 includes:

[0054] The extension member 21 is connected to the platform 11 and extends from the platform 11 to protrude from the platform 11 .

[0055] The movable cushion block 22 is supported on the extension member 21 and is higher than the extension member 21 so as to support the scrap steel plate 100 .

[0056] The extension piece 21 protrudes relative to the platform 11, which can extend the space supporting the scrap steel plate 100. The extension piece 21 is provided with a movable pad 22 supported on the extension piece 21, which can effectively support both ends of the scrap steel plate 100. On the basis of the support piece 112, the gap between the scrap steel plate 100 and the extension piece 21 can also be increased, which is convenient for the disassembly and assembly between the scrap steel plate 100 and some lifting equipment, and improves the transportation efficiency of the scrap steel plate 100. The lock for lifting the steel plate 100 may change, and the position of the movable pad 22 can be adjusted to prevent the lock from being pressed on the vehicle body 1 by the steel plate 100, so as to facilitate the removal of the lock.

[0057] In some embodiments, the extension piece 21 may be plate-shaped, and both ends of the extension piece 21 may be connected to both ends of the rectangular platform 11 in the length direction, and the length direction of the extension piece 21 may extend along the length direction of the platform 11, and the movable pad 22 may only be placed and supported on the extension piece 21. This is beneficial to controlling the preparation cost of the straddle carrier while improving the versatility of the straddle carrier.

[0058] In some embodiments, the length of the movable pad 22 may be less than or equal to the width of the extension member 21, and the length of the support member 112 may be less than or equal to the width of the platform 11. This can ensure the stable transfer of the scrap steel plate 100 and reduce possible interference.

[0059] In some embodiments, the extension component 2 may also include a plate that is integrally or separately connected to the platform 11 and functions as an extension. The present application does not limit this.

[0060] In some embodiments, the thickness of the extension plate may be 30-50 mm, or may exceed this range, which is not limited in the present application.

[0061] In some embodiments, the limiting assembly 3 includes at least two first limiting members 31 respectively connected to both sides of the platform 11, and the first limiting members 31 are higher than the platform 11. The first limiting members 31 can limit the scrap steel plate 100 to a certain extent, thereby reducing the possibility of the scrap steel plate 100 falling or colliding.

[0062] In some embodiments, the limiting assembly 3 also includes a second limiting member 32, which is inserted into the first limiting member 31 and is higher than the first limiting member 31. The first limiting member 31 and the second limiting member 32 are both rotating structures, and the axial direction of the second limiting member 32 extends along the axial direction of the first limiting member 31. The maximum diameter of the second limiting member 32 is smaller than the maximum diameter of the first limiting member 31.

[0063] The second stopper 32 is inserted into the first stopper 31 and is higher than the first stopper 31. On the basis of the first stopper 31, the stopper effect can be improved. The second stopper 32 can also play a certain guiding role on the scrap steel plate 100. The first and second stoppers are both rotary structures, and the axial direction of the second stopper 32 extends along the axial direction of the first stopper 31. When hoisting the scrap steel plate 100, the second stopper 32 on one side of the platform 11 can be pulled out from the corresponding first stopper 31, and the scrap steel plate 100 can be moved along the second stopper 32 on the other side and placed on the platform 11, and then the second stopper 32 is inserted into the corresponding first stopper 31, which is convenient for hoisting the scrap steel plate 100 and is conducive to improving the working efficiency. The maximum diameter of the second stopper 32 is smaller than the maximum diameter of the first stopper 31, which can increase the width between the second stoppers 32 of the two stopper assemblies 3, can accommodate more scrap steel plates 100, and improve the working efficiency.

[0064] In some embodiments, the first stopper 31 may be a sleeve, and one end of the sleeve is connected to the platform 11, and the second stopper 32 may be a rod or a column, and is inserted into the sleeve. For the rectangular platform 11, two spaced stopper components 3 may be provided on each side of the platform 11 in the width direction. The stopper effect is good.

[0065] In some embodiments, when the overall width of the steel plate 100 is too large, the second stopper 32 on one side can be pulled out, and the steel plate 100 can be generally moved closer to the other side. After the steel plate 100 is put down, the pulled out second stopper 32 can be plugged in. With the platform 11 as a reference, the maximum height of the second stopper 32 relative to the platform 11 can be 1 to 1.5 meters, and the stopper effect is better.

[0066] In some embodiments, the distance between the two first stoppers 31 in the width direction of the platform 11 may be greater than the maximum width of the hot rolling production line strip steel of 100 mm, so that steel plates 100 of various widths can be placed between the first stoppers 31 while leaving a gap. In this embodiment, the maximum width of the steel plate 100 can be 1450 mm. This application does not impose any limitation on this.

[0067] In some embodiments, the limiting assembly 3 may also include a railing or a guardrail, etc., which is not limited in the present application.

[0068] In some embodiments, the stopper assembly 3 further includes a reinforcing member 33 connecting the peripheral wall of the first stopper 31 and the platform 11. The reinforcing member 33 can increase the connection strength between the first stopper 31 and the platform 11, reduce the shaking that may be caused by the first stopper 31, and improve the working efficiency. The reinforcing member 33 can be a reinforcing plate or a reinforcing rod, which is not limited in the present application.

[0069] In some embodiments, the vehicle body 1 further includes a ladder 12 connected to the side of the platform 11, and the ladder 12 extends from the platform 11 to the bottom of the vehicle body 1. This facilitates the operation of the operator and helps to improve the working efficiency.

[0070] Figure 3 The schematic diagram of the structure of the transport system in some embodiments or certain embodiments of the present application is shown, with reference to Figure 3 Based on the same inventive concept, some embodiments of the present application further provide a transportation system, including:

[0071] As the straddle carrier mentioned above, the straddle carrier includes a plurality of wheels 4 which are rollingly connected to the vehicle body 1 .

[0072] A track 10 spans across at least two spans of the rolling line, and the wheels 4 roll along the track 10 to transfer the scrap steel plate 100. The spans may be steel coil production areas or steel coil storage areas.

[0073] The structure of the cross-carriage and the corresponding technical effects can be referred to above, and will not be repeated here. Adding the cross-area track 10 in conjunction with the wheels 4 of the cross-carriage is also conducive to the cross-carriage transporting the steel plate 100 and improving the working efficiency.

[0074] Figure 3 The figure shows two different spans on the production line, and divides the two spans into zone 01 and zone 02 respectively.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
