[0017] At the same time, the present application uses a secondary protection part with a specific structure. When the overall frame is hoisted through the movable lifting ring, the protection lifting rope pulls the protection slider to move horizontally to the end of the protection slide, and the protection bulge moves to the center channel of the steel coil, thereby realizing secondary protection of the steel coil while lifting, and the secondary protection does not directly contact the side of the steel coil; through the linkage design with the movable lifting ring, the protection bulge automatically enters the protection position during the lifting process, realizing the synchronous action of "hoisting and secondary protection"; the non-contact design of the protection bulge extending into the center channel of the steel coil not only avoids collision with the side of the steel coil, but also ensures that it can contact the limit in the first time when it fails.

[0040] To facilitate those skilled in the art to understand the present invention, specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0042] like Figure 1As shown, the present invention provides a steel coil transport rack, comprising an integral frame 1 and a plurality of split frames 2 arranged on the integral frame 1 (the split frames 2 can be multiple, and this application takes three as an example); the integral frame 1 is a plate-shaped structure, and three split card slots 3 with rectangular cross-sections are spaced apart on the integral frame 1. Clutch locking members 4 are provided at the four corners of the split card slots 3, and the split frames 2 are detachably fixed to the split card slots 3 through the clutch locking members 4; support legs 5 are provided at the four corners of the integral frame 1 for supporting the integral frame 1; as shown Figure 2 As shown, the split frame 2 is a ring-shaped structure, and a hump bracket 6 is welded to the lower side of the split frame 2, which is used to limit and support the steel coil; a rubber pad (not shown in the figure) is bonded to the upper surface of the hump bracket 6; four fixed lifting rings 7 are welded to the upper side of the split frame 2, and clutch locking holes 8 corresponding to the clutch locking piece 4 are provided at the four corners of the split frame 2.

[0043] There are two ways to fix the split frame 2 and the steel coil. One of the implementation methods is to tie the steel coil to the split frame 2 by a binding rope, such as Figures 3-4 As shown, the second embodiment is provided with a locking slide groove 9 and a pressing frame slide groove 10 in parallel on the split frame 2, and the steel coil locking mechanism is matched with the locking slide groove 9 and the pressing frame slide groove 10; the steel coil locking mechanism includes a locking drive block 11 that slides and fits in the left locking slide groove 9, and also includes a pressing frame linkage block 12 that slides and fits in the pressing frame slide groove 10, and the pressing frame linkage block 12 is an L-shaped cross-section; a locking drive shaft 13 is rotatably matched with a locking slide groove 9 through a bearing, and the middle part of the locking drive shaft 13 is a threaded structure that is connected to the locking drive The moving block 11 is threadedly engaged, and the inner side of the locking drive shaft 13 is fixed to the end of the locking drive shaft 13 on the other side by a coupling (the thread structures of the locking drive shafts 13 on both sides have opposite rotation directions); the outer side of the locking drive shaft 13 has a hexagonal cross-section, and the split frame 2 has a corresponding adjustment channel 14; when locking, the hexagonal sleeve is manually inserted into the adjustment channel 14 to engage with the outer side of the locking drive shaft 13, thereby shaking the locking drive shaft 13 to rotate, and the locking drive blocks 11 on the front and rear sides slide along the locking slide groove 9; Figure 6 As shown, a locking follower block 15 is slidably fitted in the locking slot 9 on the right side, and a locking slide shaft 16 is provided in the locking slot 9 on the right side, and the locking slide shaft 16 provides support for the locking follower block 15; Figure 5 As shown, a C-shaped locking transverse frame 17 is provided on the lower side of the locking driving block 11 and the locking driven block 15, and a transverse frame guide shaft 18 is vertically provided on the locking transverse frame 17. The horizontal side of the pressing frame linkage block 12 is matched with the transverse frame guide shaft 18 through a sliding bearing; the side of the pressing frame linkage block 12 is rotated with a locking guide wheel 19, and a locking guide plate 20 is vertically provided on the lower side of the split frame 2. A broken line locking guide groove 21 is opened on the locking guide plate 20, and the locking guide wheel 19 is rollingly matched in the locking guide groove 21. The locking guide groove 21 includes a straight line segment and an oblique line segment, and the straight line segment is connected to the oblique line segment; as shownFigure 6 As shown, the left and right side of the press frame linkage block 12 is provided with n-shaped steel coil press frame 22, the lower side of the steel coil press frame 22 is provided with rubber block 23 for contact with the upper surface of the steel coil.

[0044] When the steel coil is placed on the hump support 6, further fixed by the steel coil locking mechanism, the operator will extend the six-pronged sleeve into the adjusting channel 14 of the split frame 2, cooperate with the six-pronged section outside the locking drive shaft 13, and rotate the locking drive shaft 13 by shaking the six-pronged sleeve; Because the two sides of the locking drive shaft 13 are fixed by the shaft coupling and the screw rotation directions are opposite, the rotating locking drive shaft 13 will drive the left and right sides of the locking drive block 11 to slide synchronously along the locking sliding groove 9; The locking drive block 11 drives the locking driven block 15 to move synchronously through the C-shaped locking transverse frame 17, and the right locking driven block 15 slides along the locking sliding shaft 16.

[0045] When the locking transverse frame 17 moves, the vertically arranged transverse frame guide shaft 18 drives the press frame linkage block 12 to move synchronously in the horizontal direction, and the locking guide wheel 19 on the side of the press frame linkage block 12 rolls in the fold line-shaped locking guide groove 21 of the locking guide plate 20; When the guide wheel is in the straight line segment of the locking guide groove 21, the press frame linkage block 12 only moves horizontally with the locking transverse frame 17; The steel coil press frame 22 moves horizontally to both ends of the steel coil; When the guide wheel enters the inclined line segment, the inclination angle of the inclined line segment forces the locking guide wheel 19 to drive the press frame linkage block 12 to slide downward along the transverse frame guide shaft 18, and the press frame linkage block 12 drives the steel coil press frame 22 to move downward synchronously, until the rubber block 23 on the lower side of the steel coil press frame 22 is in close contact with the upper surface of the steel coil, and the vertical pressing of the steel coil is completed; When unlocking, the locking drive shaft 13 is shaken in the opposite direction, the locking drive block 11 drives the locking transverse frame 17 to move back, the locking guide wheel 19 moves upward along the inclined line segment to the straight line segment, and the steel coil press frame 22 rises under the linkage action to separate from the surface of the steel coil, realizing unlocking.

[0046] As Figures 7-9As shown, the four corners of the split card slot 3 are provided with clutch locking members 4, and the clutch locking member 4 includes a clutch shaft 24 fixed to the overall frame 1, the upper side of the clutch shaft 24 is a truncated cone structure, and the lower side of the clutch shaft 24 extends to the lower side of the overall frame 1; a clutch cavity 25 is provided inside the clutch shaft 24, and a clutch slide 26 is horizontally provided on the upper side of the clutch shaft 24, and the clutch slide 26 is connected to the clutch cavity 25; a clutch fixing plate 27 is provided on the side of the clutch slide 26 close to the clutch cavity 25, and a clutch locking block 28 is slidably fitted in the clutch slide 26, and the side of the clutch locking block 28 is a gradually expanding arc structure. When the clutch locking hole 8 on the split frame 2 is inserted into the clutch shaft 24, it contacts the side of the clutch locking block 28; the inner side of the clutch locking block 28 is connected to one end of the clutch rope 29; the other end of the clutch rope 29 is passed through When the clutch is unlocked, the linkage clutch pull plate 30 is pulled and the clutch locking block 28 is retracted by the clutch rope 29.

[0047] When the clutch locking member 4 is in operation, the inner wall of the clutch locking hole 8 first contacts the gradually expanding arc-shaped structure of the clutch locking block 28; as the split frame 2 moves downward along the clutch shaft 24, the arc-shaped structure is squeezed, causing the clutch locking block 28 to overcome the elastic force of the clutch spring 31 and slide along the clutch slide 26 into the clutch cavity 25, and the clutch spring 31 is compressed; when the split frame 2 is completely moved to the lower side of the clutch shaft 24, the squeezing effect of the clutch locking hole 8 and the clutch locking block 28 disappears, and the clutch spring 31 pushes the clutch locking block 28 to return to its original position outward along the clutch slide 26, so that the outer part of the clutch locking block 28 protrudes from the clutch slide 26 and is stuck on the edge of the clutch locking hole 8 of the split frame 2, thereby locking the split frame 2 and firmly fixing the split frame 2 in the split card slot 3 of the integral frame 1.

[0048] When unlocking, the operator pulls the linkage clutch pull plate 30, which drives the clutch locking block 28 to slide into the clutch cavity 25 through the clutch rope 29, compressing the clutch spring 31, so that the clutch locking block 28 is completely retracted into the clutch slide 26, and disengaged from the clutch locking hole 8 of the split frame 2; at this time, the split frame 2 can move upward along the clutch shaft 24 and disengage from the split card slot 3 of the integral frame 1, thereby realizing rapid separation of the split frame 2 from the integral frame 1.

[0049] When the whole frame 1 is hoisted and moved, the split frame 2 is detachably fixed to the whole frame 1 through the clutch locking member 4; if the clutch locking member 4 is damaged, the steel coil and the split frame 2 will fall off the whole frame 1; in order to solve this problem, Figure 7 、 Figure 10 As shown, the integral frame 1 is provided with a secondary protective member, which is used to clamp the two sides of the steel coil when the steel coil is hoisted and transferred, and perform secondary locking protection; the four corners of the integral frame 1 are respectively provided with a protective slide 33, and a protective guide shaft 34 is horizontally provided in the protective slide 33. The protective slider 35 slides in the protective slide 33, and the protective guide shaft 34 supports the protective slider 35. The protective guide shaft 34 is passed through a protective return spring 36, and the protective return spring 36 is stuck between the protective slider 35 and the protective slide 33; the upper side of the protective slider 35 extends out of the protective slide 33 and is fixed to the protective transverse plate 37, and the protective transverse plate 37 is provided with a protective protrusion 38 corresponding to the steel coil; The side of the protection slide 33 is provided with a corresponding protection guide wheel 39, and the four corners of the integral frame 1 are respectively provided with a movable lifting ring 40, and the integral frame 1 is provided with a broken line protection lifting hole 41; the movable lifting ring 40 is connected to one end of the protection lifting rope 42, and the other end of the protection lifting rope 42 passes through the protection lifting hole 41, bypasses the protection guide wheel 39 and is fixed to the side of the protection slider 35; when the integral frame 1 is lifted and moved, the movable lifting ring 40 is pulled, and the protection lifting rope 42 pulls the protection slider 35 to move horizontally to the end of the protection slide 33, and the protection protrusion 38 moves to the central channel of the steel coil (not in contact with the steel coil); when the locking of the steel coil fails, the protection protrusion 38 limits the steel coil for secondary protection.

[0050] When the whole frame 1 is hoisted and moved, the operator hoists the whole frame 1 through the movable hoisting ring 40, at this time the movable hoisting ring 40 pulls the protection sling 42, the protection sling 42 changes the direction of force along the protection guide wheel 39, drives the protection sliding block 35 to slide along the protection slide 33; At the same time, the protection return spring 36 is compressed, until the protection sliding block 35 moves to the end of the protection slide 33; At this time, the protection transverse plate 37 moves synchronously with the protection sliding block 35, drives the protection convex 38 on it to extend into the center channel of the steel coil, and the protection convex 38 keeps a non-contact state with the steel coil, which will not knock the side of the steel coil, and has the function of secondary protection; When the clutch locking piece 4 is damaged, or the steel coil itself is not fixed firmly, the steel coil or the split frame 2 appears the trend of falling off, the steel coil will be offset under the action of gravity, its inner wall will contact with the protection convex 38 in the center channel in advance, and the side wall of the steel coil will contact with the protection transverse plate 37; Prevent the steel coil from further offsetting or falling, so as to realize the secondary protection of the steel coil and avoid safety accidents; After hoisting is completed, the movable hoisting ring 40 is loosened, the protection return spring 36 releases the elastic potential energy, pushes the protection sliding block 35 to reset along the protection guide shaft 34, the protection sling 42 returns with the sliding block, drives the movable hoisting ring 40 to reset, the protection convex 38 exits the center channel of the steel coil, and does not affect the loading and unloading operation of the steel coil.

[0051] The application realizes the secondary protection of the steel coil while hoisting through the specific structure of the secondary protection piece, the protection sling 42 pulls the protection sliding block 35 to move transversely to the end of the protection slide 33, and the protection convex 38 moves to the center channel of the steel coil when the whole frame 1 is hoisted through the movable hoisting ring 40, realizes the secondary protection of the steel coil while hoisting, and the secondary protection does not directly contact the side of the steel coil; Through the linkage design with the movable hoisting ring 40, the protection convex 38 automatically enters the protection position in the hoisting process, realizes the synchronous action of "hoisting and secondary protection"; The non-contact design of the protection convex 38 extending into the center channel of the steel coil avoids knocking the side of the steel coil, and ensures that it can contact and limit in the first time when it fails.
