[0001] The present application relates to the technical field of steel wire coil carrying clamp, in particular to a special anti-falling carrying clamp for steel wire coil transportation. BACKGROUND

[0002] In the field of industrial production, steel wire coil is an important raw material or semi-finished product in the industry of metal processing, building and mechanical manufacturing, etc., which has a wide range of applications and is usually characterized by large weight, large volume and cylindrical shape.

The adjusting screw is tightened against the first motor. A gearbox is mounted on the second sliding seat. A pulley is fixedly mounted on the input shaft of the gearbox. The pulley on the input shaft of the gearbox and the pulley on the output shaft of the first motor are connected by a belt for transmission.

[0009] Furthermore, a sprocket is fixedly mounted on the output shaft of the gearbox, and a sprocket is fixedly mounted on the rotating cylinder. The sprocket on the output shaft of the gearbox and the sprocket on the rotating cylinder are connected by a chain for transmission. Two fixed posts are fixed to the right end of the second sliding seat, and clamping arms are mounted on the fixed posts. A third hydraulic rod is mounted between the upper ends of the two clamping arms, and clamping plates are bolted to both clamping arms. Rubber pads are fixed on the clamping plates. A reduction ring is mounted on the rotating cylinder by a flat key, and the two clamping plates are clamped on the reduction ring.

[0010] Furthermore, a connecting cylinder is bolted to the left end of the second sliding seat, and a baffle is fixed to the left end of the connecting cylinder. The baffle has four through slots, and a plate seat is bolted to each of the four tensioning plates. The plate seat is located in the through slot of the baffle, and two rollers are installed on the plate seat. The two rollers contact the left and right sides of the baffle respectively.

[0011] Furthermore, a first sleeve and a second sleeve are installed on each of the three threaded rods on the end plate.

Both the first movable seat and the second movable seat are movable on the rotating cylinder.

[0012] Furthermore, a fixed plate is fixedly installed on the first sliding seat, four guide posts are fixedly installed on the fixed plate, and a lifting plate that can move up and down is installed on the four guide posts. A mating seat is installed at the lower end of the lifting plate. A second slide rail is installed on the fixed plate, and a sliding block that can slide left and right is installed on the second slide rail. The sliding block is provided with a threaded hole. A second lead screw is installed on the fixed plate. The second lead screw is threadedly engaged with the threaded hole on the sliding block.

[0013] Furthermore, a mounting plate is bolted onto the sliding block, and a third slide rail is obliquely mounted on the mounting plate. The mating seat slides on the third slide rail, and two support legs are fixed on the fixing frame, both of which are fixed to the lifting plate.

[0014] Furthermore, a sliding block is installed on the fixed frame, the toothed plate slides on the sliding block, and a rotatable gear is installed on the fixed frame. The gear meshes with the toothed plate, and the shafts of two adjacent gears are connected for transmission through a universal coupling. A worm gear reducer is installed on the fixed frame, and a second electric motor for driving the gear rotation is installed on the worm gear reducer.

[0015] This invention provides a special anti-detachment handling clamp for transporting steel wire coils, which has the following beneficial effects: This invention constructs a two-way fixing system to achieve stable locking of the wire roll from both the inside and outside: internally, a rotating cylinder drives the first lead screw to rotate, causing the end plate and threaded rod to move synchronously, making the first and second movable seats slide along the rotating cylinder. The inclined structure of the two pushes the four tensioning plates to expand outward, completing the tensioning and positioning from the inner diameter of the wire roll and preventing its axial movement; externally, it relies on the external clamping structure driven by the second motor. The second motor drives the worm gear reducer to operate, and the reducer outputs power to drive the gear to rotate. The gear meshes with the toothed plate, causing the toothed plate to slide stably along the sliding block of the fixing frame. Finally, the clamping plate on the toothed plate accurately fits the outer wall of the wire roll, forming a strong clamping force from the outside. The internal tensioning and external clamping exert force in both directions and work together to completely eliminate the risk of radial displacement or loosening and falling off of the wire roll during transportation. Especially for heavy and high-diameter wire rolls, the anti-detachment reliability is far superior to the traditional single fixing method.

[0016] Furthermore, in this invention, the first sliding seat on the base can be driven to slide along the slide groove by the second hydraulic rod, and the second sliding seat can be driven to slide along the first slide rail by the first hydraulic rod. The two work together to achieve flexible adjustment of the lateral position of the clamp. The lifting plate slides along the third slide rail through the mating seat, which can realize the vertical height adjustment of the fixed frame and the clamping plate. In addition, the toothed plate can be synchronously extended and retracted along the slide block of the fixed frame through the transmission of the second motor and gears. Combined with the design that the expansion range of the tensioning plate can be adjusted through the first movable seat and the second movable seat, the outer clamping range and the inner tension range can be precisely adjusted according to the diameter, length, inner diameter and other specifications of the wire coil, adapting to the handling needs of different types of wire coils. There is no need to design clamps separately for different specifications of wire coils, which greatly improves the versatility of the equipment. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figures 1 to 14 Example 1: This invention proposes a special anti-detachment handling clamp for transporting steel wire coils, comprising: a base 1; four lifting lugs 11 are locked onto the base 1 by nuts; a first sliding seat 12 and a second sliding seat 2 are mounted on the base 1; a rotating cylinder 21 is mounted on the second sliding seat 2 by bearings; a mating cylinder 22 is bolted to the right end of the rotating cylinder 21; the mating cylinder 22 has a threaded hole; a first lead screw 221 is installed inside the rotating cylinder 21, and the first lead screw 221 is threadedly engaged with the threaded hole on the mating cylinder 22; an end plate 222 is locked onto the left end of the first lead screw 221 by nuts. Three threaded rods are locked onto the end plate 222 by nuts. A first movable seat 23 and a second movable seat 24 are mounted on the three threaded rods. Both the first movable seat 23 and the second movable seat 24 are provided with an inclined structure. Tensioning plates 25 are installed on the first movable seat 23 and the second movable seat 24. There are four tensioning plates 25. A mating block 241 that can be installed with the first movable seat 23 and the second movable seat 24 is installed on the tensioning plate 25. A fixing frame 34 is provided above the first sliding seat 12. Toothed plates 342 are arrayed on the fixing frame 34. A clamping plate 3421 is fixed on the toothed plates 342.

[0036] In this embodiment of the invention, a first slide rail 14 is bolted to the base 1, and a second sliding seat 2 slides on the first slide rail 14. A cylinder seat 15 is bolted to the base 1, and a first hydraulic rod 151 is mounted on the cylinder seat 15. A connecting plate 1511 is bolted to the piston rod of the first hydraulic rod 151, and the connecting plate 1511 is fixed to the right side of the second sliding seat 2. A sliding groove is provided on the base 1, and a rolling wheel 121 is mounted on the lower end of the first sliding seat 12 via a bearing. The rolling wheel 121 rolls in the sliding groove on the base 1. Two second hydraulic rods 13 are fixedly mounted on the base 1, and the pistons of the two second hydraulic rods 13... The rods are all fixedly connected to the first sliding seat 12. Their function is to: drive the connecting plate 1511 and the second sliding seat 2 to slide stably along the first slide rail 14 by extending and retracting the piston rod of the first hydraulic rod 151, thereby realizing the lateral position adjustment of the second sliding seat 2 on the base 1; at the same time, drive the first sliding seat 12 to roll smoothly along the slide groove of the base 1 by means of the lower rolling wheel 121, thereby realizing the lateral position adjustment of the first sliding seat 12 on the base 1, and thus providing lateral position adjustment space for the tensioning structure on the second sliding seat 2 and the external clamping structure on the first sliding seat 12 respectively.

[0037] In this embodiment of the invention, a set of mounting frames 27 are fixed on the second sliding seat 2. The mounting frames 27 have a waist-shaped through groove. A first motor 28 is mounted on the mounting frames 27 by bolts. A pulley is fixedly mounted on the output shaft of the first motor 28. An adjusting screw 271 is threaded onto the mounting frames 27, and the adjusting screw 271 is tightened against the first motor 28. A gearbox 29 is mounted on the second sliding seat 2. A pulley is fixedly mounted on the input shaft of the gearbox 29. The pulley on the input shaft of the gearbox 29 is connected to the output shaft of the first motor 28. The pulleys on the gearbox 29 are connected by a belt for transmission. A sprocket is fixedly mounted on the output shaft of the gearbox 29, and a sprocket is fixed on the rotating drum 21. The sprockets on the output shaft of the gearbox 29 and the sprockets on the rotating drum 21 are connected by a chain for transmission. Two fixed posts 212 are fixed to the right end of the second sliding seat 2. Clamping arms 213 are mounted on the fixed posts 212. A third hydraulic rod 214 is mounted between the upper ends of the two clamping arms 213. Clamping plates 2131 are bolted to both clamping arms 213, and rubber pads 213 are fixed to the clamping plates 2131. 2. A reduction ring 215 is mounted on the rotating cylinder 21 via a flat key. Two clamping plates 2131 are held in place by the reduction ring 215. Their function is as follows: the first motor 28 acts as a power source, transmitting power to the gearbox 29 via a belt drive between the output shaft pulley and the input shaft pulley. After the gearbox 29 adjusts the transmission ratio, the rotating cylinder 21 is driven to rotate stably via a chain drive between the output shaft sprocket and the sprocket of the rotating cylinder 21, providing power for the subsequent tensioning action of the tensioning plate 25. The waist-shaped through groove of the mounting frame 27 facilitates the adjustment of the first motor 215. The installation position of 8, together with the adjusting screw 271, tightens the first motor 28, which can flexibly adjust the belt tension to ensure stable transmission without slippage. On the other hand, the third hydraulic rod 214 can drive the two clamping arms 213 to open and close around the fixed column 212, and drive the clamping plate 2131 to clamp or release the deceleration ring 215 on the rotating cylinder 21. When clamping, the clamping plate 2131 is in close contact with the deceleration ring 215 through the rubber pad 2132, and uses friction to decelerate or brake the rotating cylinder 21, so as to avoid the rotating cylinder 21 from losing control of the tensioning action due to continuous rotation of inertia.

[0038] In this embodiment of the invention, a connecting cylinder 26 is bolted to the left end of the second sliding seat 2, and a baffle 261 is fixed to the left end of the connecting cylinder 26. The baffle 261 has four through slots, and plate seats 251 are bolted to each of the four tensioning plates 25. The plate seats 251 are located within the through slots on the baffle 261, and two rollers 2511 are mounted on the plate seats 251. The two rollers 2511 contact the left and right sides of the baffle 261 respectively. A first sleeve 223 and a second sleeve 224 are mounted on each of the three threaded rods on the end plate 222. The first sleeve 223 is located between the first movable seat 23 and the second movable seat. Between 24, the second sleeve 224 is located between the first movable seat 23 and the end plate 222, and both the first movable seat 23 and the second movable seat 24 are movable on the rotating cylinder 21. Their function is: the plate seat 251 of the tensioning plate 25 is embedded in the through groove of the baffle 261, and the roller 2511 contacts the two sides of the baffle 261, which accurately guides the radial expansion trajectory of the tensioning plate 25. When the first lead screw 221 drives the end plate 222 to move, the two movable seats slide stably along the rotating cylinder 21 through the limiting effect of the sleeve, thereby pushing the tensioning plate 25 to expand or contract evenly, ensuring the balance of tension force.

[0039] In Embodiment Two, based on Embodiment One, a fixed plate 3 is fixedly installed on the first sliding seat 12. Four guide posts 31 are fixedly installed on the fixed plate 3. A lifting plate 32 that can move up and down is installed on the four guide posts 31. A mating seat 321 is installed at the lower end of the lifting plate 32. A second slide rail 331 is installed on the fixed plate 3. A sliding block 332 that can slide left and right is installed on the second slide rail 331. The sliding block 332 is provided with a threaded hole. A second lead screw 333 is installed on the fixed plate 3. The second lead screw 333 is threadedly engaged with the threaded hole on the sliding block 332. A handwheel 334 is installed on the left end of the 3. A mounting plate 335 is bolted to the sliding block 332. A third slide rail 336 is obliquely mounted on the mounting plate 335. The mating seat 321 slides on the third slide rail 336. Its function is to drive the second lead screw 333 to rotate by rotating the handwheel 334. By utilizing the threaded engagement between the second lead screw 333 and the sliding block 332, the sliding block 332 is driven to slide left and right along the second slide rail 331. The movement of the sliding block 332 will drive the lifting plate 32 to move up and down along the four guide posts 31 through the mating seat 321, thereby realizing the height adjustment of the lifting plate 32.

[0040] In Example 3, based on Examples 1 and 2, two support legs 35 are fixed on the fixed frame 34, and both support legs 35 are fixed on the lifting plate 32. A sliding block 341 is installed on the fixed frame 34, and the toothed plate 342 slides on the sliding block 341. A rotatable gear 343 is installed on the fixed frame 34, and the gear 343 meshes with the toothed plate 342. The rotating shafts of two adjacent gears 343 are connected for transmission through a universal coupling. A worm gear reducer 344 is installed on the fixed frame 34, and a second motor 345 for driving the gear 343 to rotate is installed on the worm gear reducer 344. Its function is: the second motor 345 drives the gear 343 to rotate through the worm gear reducer 344, and the meshing transmission between the gear 343 and the toothed plate 342, combined with the sliding guide of the toothed plate 342 along the sliding block 341, realizes the extension and retraction of the toothed plate 342.

[0041] The working principle of this invention is as follows: First, the second sliding seat 2 is driven to slide along the first slide rail 14 by the first hydraulic rod 151 on the base 1. At the same time, the first sliding seat 12 is driven to slide along the slide groove of the base 1 by the second hydraulic rod 13 with the help of the rolling wheel 121. The lateral positions of the two are adjusted according to the length specifications of the wire coil so that the tensioning structure and the external clamping structure are in the corresponding working positions. During the internal tensioning operation, the first motor 28 transmits power to the gearbox 29 through belt transmission. After speed change, the rotating cylinder 21 is driven to rotate through chain transmission. The first lead screw 221 in the rotating cylinder 21 is threadedly engaged with the mating cylinder 22, which drives the end plate 222 and the threaded rod to move axially, causing the first movable seat 23 and the second movable seat 24 to slide along the rotating cylinder 21. Under the limit of the first sleeve 223 and the second sleeve 224, the two movable seats push the tensioning plate 25 to expand radially along the through groove of the baffle 261 through the inclined structure, so as to achieve tensioning and fixing from the inner diameter of the wire coil. If deceleration or braking is required, the third hydraulic rod 214 The clamping plate 2131 of the drive clamping arm 213 clamps the reduction ring 215 of the rotating cylinder 21, achieving precise control through the friction of the rubber pad 2132; the external clamping action is synchronized, and the handwheel 334 is turned to drive the second lead screw 333 to move the sliding block 332 along the second slide rail 331. The inclined third slide rail 336 of the mounting plate 335 drives the mating seat 321 to slide, causing the lifting plate 32 to adjust its height up and down along the guide post 31. Then the second motor 345 drives the worm gear reducer 3... 44 drives the gear 343 to rotate, and through the meshing transmission between the gear 343 and the toothed plate 342 (the universal coupling ensures that the multiple gears 343 are synchronized), the toothed plate 342 slides along the slide block 341, driving the clamping plate 3421 to clamp from the outer diameter of the wire coil, forming a bidirectional fixation with the inner tension. Throughout the process, each component is precisely guided by structures such as slide rails, slide grooves, and guide posts 31. The combination of hydraulic and motor drives ensures stable and efficient operation, ultimately achieving safe, precise, and efficient handling of the wire coil.
