Description

Technical Field

[0001] This utility model relates to the field of steel bar transportation technology, and in particular to a steel bar coil hoisting and gripping device. Background Technology

[0002] To facilitate the transportation of steel bars, they are usually rolled into discs to form steel bar coils. After processing, the steel bars are rolled into coils. The steel bar coils have a neat structure and are packaged in a regular manner. Steel bar coils are divided into finely rolled and regular coils and bulk coils of raw materials.

[0003] When the steel bar coil is hoisted, it is grabbed by a steel bar coil hoisting and grabbing device. When grabbing the steel bar coil, the relevant steel bar coil hoisting and grabbing device abuts against the inner cavity of the annular steel bar coil through the internal support mechanism to achieve the grabbing and fixing of the steel bar coil.

[0004] When using steel coils, they need to be hoisted onto a reeling plate with a central column for laying out. The internal support mechanism in the steel coil hoisting and grabbing device and the central column on the reeling plate interfere with each other, making it impossible for the steel coil hoisting and grabbing device to place the steel coils conveniently and efficiently on the reeling plate, thus affecting the hoisting efficiency of the steel coils. Utility Model Content

[0005] The purpose of this invention is to provide a steel bar coil hoisting and gripping device that can conveniently and efficiently grip and place steel bar coils.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The rebar coil hoisting and gripping device includes:

[0008] Support frame;

[0009] The transmission assembly includes two first transmission arms and two second transmission arms. One end of the first transmission arm is a first connecting end and the other end is a first driving end. The first connecting end is rotatably connected to the support frame. One end of the second transmission arm is a second connecting end and the other end is a second driving end. The two second connecting ends are rotatably connected to the two first driving ends in a one-to-one correspondence. The two second transmission arms are arranged crosswise and rotatably connected at the intersection.

[0010] Two clamping frames are connected to the two second driving ends of the transmission assembly in a one-to-one correspondence. When the support frame moves away from the second driving end, the two second driving ends of the transmission assembly drive the two clamping frames to move closer to each other and clamp the steel coil from the outside.

[0011] Preferably, there are two transmission components, with the second drive end on one side of the two transmission components connected to one clamping frame, and the second drive end on the other side connected to the other clamping frame.

[0012] Preferably, the clamping frame includes:

[0013] A cross brace beam is connected to the second drive end;

[0014] Multiple load-bearing arms are arranged sequentially at intervals along the length of the cross brace beam, with one end connected to the cross brace beam;

[0015] Multiple clamping arms are connected one-to-one with the multiple bearing arms.

[0016] Preferably, the clamping frame includes two load-bearing arms, which are connected by a reinforcing beam, and the two clamping arms are connected one-to-one to opposite sides of the two load-bearing arms.

[0017] Preferably, the clamping arm is detachably connected to the supporting arm.

[0018] Preferably, the wall surface of the clamping arm that clamps the steel coil is provided with a serrated structure.

[0019] Preferably, the device also includes a pressure seat, which is rotatably connected to the second transmission arm. When the two clamping frames hold the steel coil, the pressure seat abuts against the steel coil from the top.

[0020] Preferably, a locking mechanism is also included, which is configured to lock the clamp to the support frame.

[0021] Preferably, the locking mechanism includes a locking hook and a locking head, one of which is disposed on the support frame and the other on the second transmission arm. When the locking hook is hooked onto the locking head, the clamping frame is locked to the support frame.

[0022] Preferably, the locking hook is rotatably connected to the support frame, the locking head is fixed to the second transmission arm, and the locking hook is provided with a guide surface;

[0023] When the support frame descends vertically towards the locking head, the locking head can push against the guide surface, causing the hook head of the locking hook to pass over the locking head;

[0024] When the hook head of the locking hook passes over the locking head and the support frame rises vertically away from the locking head, the hook head of the locking hook can hook onto the locking head.

[0025] The beneficial effects of this utility model are:

[0026] The transmission assembly includes two first transmission arms and two second transmission arms. The first transmission arms are connected to the support frame, and the second transmission arms are connected to the clamping frame. The two second transmission arms are arranged crosswise and rotatably connected at the intersection. This allows the two first transmission arms of the transmission assembly to swing towards each other when the support frame rises vertically relative to the rebar coil after the rebar coil hoisting and gripping device is placed on the rebar coil. Under the action of gravity, the two first drive ends move closer to each other. When the two first drive ends move closer to each other, they drive the two second connecting ends to move closer to each other. When the two second connecting ends move closer to each other, they drive the two second drive ends to move closer to each other. Finally, the two second drive ends drive the two clamping frames to clamp the rebar coil from the outside, thus enabling convenient gripping of the rebar coil. Furthermore, when the rebar coil is subsequently placed on the pay-off reel, the transmission assembly and the two clamping frames that clamp the rebar coil from the outside do not interfere with the central column on the pay-off reel. This allows the rebar coil hoisting and gripping device to directly drive the rebar coil to be fitted onto the central column and then placed on the pay-off reel, improving the placement efficiency of the rebar coil.

[0045] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1 to 3As shown, this utility model provides a rebar coil hoisting and gripping device, including a support frame 1, a transmission assembly 2, and two clamping frames 3. The transmission assembly 2 includes two first transmission arms 21 and two second transmission arms 22. One end of each first transmission arm 21 is a first connecting end, and the other end is a first driving end, rotatably connected to the support frame 1. One end of each second transmission arm 22 is a second connecting end, and the other end is a second driving end, rotatably connected to the two first driving ends in a one-to-one correspondence. The two second transmission arms 22 are arranged crosswise and rotatably connected at the intersection. The two clamping frames 3 are connected to the two second driving ends of the transmission assembly 2 in a one-to-one correspondence. When the support frame 1 moves away from the second driving ends, the two second driving ends of the transmission assembly 2 drive the two clamping frames 3 to move closer together, clamping the rebar coil 100 from the outside.

[0047] In this invention, the transmission assembly 2 includes two first transmission arms 21 and two second transmission arms 22. The first transmission arms 21 are connected to the support frame 1, and the second transmission arms 22 are connected to the clamping frame 3. The two second transmission arms 22 are arranged crosswise and rotatably connected at the intersection. This allows the steel coil hoisting and gripping device to be positioned on the steel coil 100. When the support frame 1 rises vertically relative to the steel coil 100, the two first transmission arms 21 of the transmission assembly 2 swing towards each other, and the two first driving ends approach each other under the action of gravity. When the two first driving ends approach each other, they drive the two second transmission arms 22... When the connecting ends approach each other, the two second connecting ends approach each other, which in turn drive the two second driving ends to approach each other. Finally, the two second driving ends drive the two clamping frames 3 to clamp the steel coil 100 from the outside, thus enabling convenient gripping of the steel coil 100. Furthermore, when the steel coil 100 is subsequently placed on the pay-off reel, the transmission component 2 that clamps the steel coil 100 from the outside and the two clamping frames 3 do not interfere with the central column on the pay-off reel. This allows the steel coil hoisting and gripping device to directly drive the steel coil 100 to be fitted onto the central column and then placed on the pay-off reel, improving the placement efficiency of the steel coil 100.

[0048] Specifically, the cross-sectional area of ​​the second transmission arm 22 gradually increases from the second connecting end to the second driving end. This arrangement improves the structural strength of the end of the second transmission arm 22 connected to the clamping frame 3, ensuring the safety and reliability of the second transmission arm 22 when driving the clamping frame 3 to move.

[0049] More specifically, the first transmission arm 21 includes two elongated first plates, and the bottom of the support frame 1 is provided with a connecting ear 11, which is clamped between the two first plates and rotatably connected by a pin.

[0050] More specifically, the second transmission arm 22 includes two elongated second plates, which are rotatably connected to the two first plates by pins.

[0051] In this embodiment, the two first transmission arms 21 extend in opposite directions without crossing each other. The two second plates of the second transmission arm 22 can be located between the two first plates of the first transmission arm 21 or outside the two first plates of the first transmission arm 21. The width of the second plate gradually increases from the second connecting end to the second driving end.

[0052] In other embodiments, the two first transmission arms 21 may also be arranged crosswise and rotatably connected at the intersection.

[0053] Specifically, there are two transmission components 2. The second drive ends on one side of both transmission components 2 are connected to one clamping frame 3, and the second drive ends on the other side are connected to another clamping frame 3. When the two clamping frames 3 clamp the rebar coil 100, the central column on the pay-off reel can extend between the two transmission components 2. The above arrangement, while ensuring stable and reliable connection and support for the two clamping frames 3, further avoids interference between the rebar coil hoisting and gripping device and the central column on the pay-off reel.

[0054] More specifically, the support frame 1 has a frame-shaped structure, and when the two clamping frames 3 clamp the rebar coil 100, the central column on the pay-off reel can extend into the support frame 1. The above arrangement further avoids interference between the rebar coil hoisting and gripping device and the central column on the pay-off reel.

[0055] In this embodiment, if the axial dimension of the steel coil 100 is small or the axial dimension of the central column on the wire feeding reel is large, then when the steel coil 100 is placed on the wire feeding reel, the central column can pass through the steel coil 100, the gap between the two transmission components 2 and the support frame 1 in sequence without interference.

[0056] In other embodiments, the support frame 1 may also be annular or other hollow structures, as long as the central column can pass through when the steel coil 100 is placed on the wire reel.

[0057] Specifically, the clamping frame 3 includes a cross brace 31, load-bearing arms 32, and clamping arms 33. The cross brace 31 is connected to the second drive end. Multiple load-bearing arms 32 are arranged at intervals along the length of the cross brace 31, with one end connected to the cross brace 31. Multiple clamping arms 33 are correspondingly connected to the load-bearing arms 32. This arrangement enables the clamping frame 3 to achieve multi-point clamping of the rebar coil 100, making it safer and more reliable.

[0058] More specifically, the clamping frame 3 includes two supporting arms 32 connected by a reinforcing beam 34, and two clamping arms 33 connected one-to-one to the opposite sides of the two supporting arms 32. This arrangement allows the two clamping frames 3 to clamp the rebar coil 100 using four clamping arms 33, making it suitable for rebar coils 100 of various diameters.

[0059] In this embodiment, two transmission components 2 are spaced apart in the horizontal direction, and the cross brace 31 extends horizontally. The second drive end on one side of the two transmission components 2 is connected to the cross brace 31 of a clamping frame 3, and the second drive end on the other side is connected to the cross brace 31 of another clamping frame 3. The two bearing arms 32 connected to a cross brace 31 are located between the two second transmission arms 22.

[0060] Specifically, the clamping arm 33 is detachably connected to the bearing arm 32. This arrangement allows for the replacement of the appropriate clamping arm 33 according to the diameter and axial dimensions of the rebar coil 100, and also allows for the replacement of the clamping arm 33 when it is worn to the point of being unsuitable.

[0061] More specifically, the wall surface of the clamping arm 33 that clamps the steel coil 100 is provided with a serrated structure 331. The above-mentioned configuration enables the clamping arm 33 to clamp the steel coil 100 more safely and reliably.

[0062] In this embodiment, the clamping arm 33 is detachably connected to the bearing arm 32 by fasteners such as bolts and nuts. Both the clamping arm 33 and the bearing arm 32 are strip-shaped and are closely connected to each other. The clamping arm 33 protrudes from one side of the bearing arm 32 and has a serrated structure 331 at the protrusion. The opposing sides of the bearing arms 32 of the two transmission components 2 extend in an arc shape. When the opposing sides of the bearing arms 32 of the two transmission components 2 are parallel to each other, the distance between the opposing sides gradually increases in the direction away from the cross brace beam 31. The opposing sides of the bearing arms 32 of the two transmission components 2 extend in an arc shape. When the opposing sides of the clamping arms 33 of the two transmission components 2 are parallel to each other, the distance between the opposing sides gradually increases in the direction away from the cross brace beam 31.

[0063] Specifically, the rebar coil hoisting and gripping device also includes a pressure seat 4, which is rotatably connected to the second transmission arm 22. When the two clamping frames 3 clamp the rebar coil 100, the pressure seat 4 abuts against the rebar coil 100 from the top. The pressure seat 4 can provide alignment support for the two clamping frames 3. During the clamping operation, the two clamping frames 3 can rotate relative to the pressure seat 4 to clamp the rebar coil 100 more accurately.

[0064] More specifically, each of the two transmission components 2 is provided with a pressing seat 4. When the pressing seat 4 hangs down under the action of gravity, its bottom surface is horizontal, which can press against the top surface of the steel coil 100.

[0065] In this embodiment, the pressure seat 4 is rotatably connected to the cross connection of the two second transmission arms 22 of the transmission assembly 2, so that the two clamping frames 3 are symmetrically arranged relative to the pressure seat 4.

[0066] Specifically, the rebar coil hoisting and gripping device also includes a locking mechanism 5, which is configured to lock the clamping frame 3 to the support frame 1. Through the locking mechanism 5, before the clamping operation, the transmission assembly 2 can easily drive the two clamping frames 3 to be fitted onto the outside of the rebar coil 100. After the fitting is completed, the locking mechanism 5 only needs to release the lock on the clamping frames 3, and the support frame 1 can then drive the two clamping frames 3 to clamp the rebar coil 100 when it is lifted.

[0067] More specifically, the locking mechanism 5 includes a locking hook 51 and a locking head 52. One of the locking hook 51 is located on the support frame 1, and the other is located on the second transmission arm 22. When the locking hook 51 is hooked onto the locking head 52, the clamping frame 3 is locked to the support frame 1. The above configuration makes the locking and unlocking operations simpler.

[0068] More specifically, the locking hook 51 is rotatably connected to the support frame 1, the locking head 52 is fixed to the second transmission arm 22, and the locking hook 51 is provided with a guide surface 511. When the support frame 1 descends vertically and approaches the locking head 52, the locking head 52 can push against the guide surface 511 to make the hook head of the locking hook 51 pass over the locking head 52; when the hook head of the locking hook 51 passes over the locking head 52 and the support frame 1 rises vertically away from the locking head 52, the hook head of the locking hook 51 can hook onto the locking head 52. The above setup allows the support frame 1 to be lowered further after the rebar coil 100 is placed, moving it closer to the two clamping frames 3. This allows the locking hook 51 to automatically hook onto the locking head 52, thereby locking the clamping frame 3 onto the support frame 1 and releasing the rebar coil 100. Then, the rebar coil lifting and grabbing device can be lifted to perform subsequent operations conveniently and efficiently. When grabbing the next rebar coil 100, the rebar coil lifting and grabbing device is placed on the rebar coil 100, and then the locking hook 51 is manually operated to release the hook from the locking head 52. After that, the rebar coil lifting and grabbing device can be lifted to grab the next rebar coil 100.

[0069] In this embodiment, the locking hook 51 is rotatably connected to the connecting ear 11 of the support frame 1. The locking hook 51 is also provided with an operating rod 512 to facilitate operation by the operator. The locking head 52 is located on the side of one transmission component 2 away from the other transmission component 2 and is provided at the rotatable connection of the two second transmission arms 22.

[0070] In other embodiments, the locking mechanism 5 may also include a locking pin, and the first transmission arm 21 and the two second transmission arms 22 are respectively provided with locking holes. When the locking pin passes through the locking holes on the first transmission arm 21 and the two second transmission arms 22, it locks the clamping frame 3.

[0071] Specifically, the top of the support frame 1 is provided with a lifting lug 12, and the lifting lug 12 is connected to a chain 6. The support frame 1 can be connected to the hoisting device through the chain 6.

[0072] More specifically, the support frame 1 has a rectangular frame structure, with a lifting lug 12 at each of the four corners.

[0073] In this embodiment, the hoisting device is a conventional overhead crane or other lifting device in the art, and its specific structure and working principle will not be described in detail here.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
