Description

Technical Field

[0001] This utility model belongs to the field of steel coil technology, specifically a mechanism for preventing loosening of steel coil reels. Background Technology

[0002] A steel coil is a steel product made by cold-rolling or hot-rolling steel into an extra-long strip and then winding it around a drum. It is formed by winding extra-long steel strips for convenient transportation, storage and processing.

[0003] Among them, a search revealed application CN202121356918.1, a steel coil take-up reel. This steel coil take-up reel features a locking sleeve that fixes the inner liner of the steel coil and the driven disc to the driving disc. During winding, the inner liner of the steel coil rotates with the driving disc. When the output speed of the steel strip is less than the rotation speed of the driving disc, the inner liner of the steel coil rolls on the outer ring of the bearing, which can prevent wear on the inner liner of the steel coil and ensure the winding quality of the steel coil. However, the following are its shortcomings:

[0004] When workers use this type of steel coil take-up reel to reel in steel coils, the locking sleeve is attached to the side of the inner liner of the steel coil. The locking sleeve is tightened along the thread to fix the position of the inner liner and the driven plate before reeling begins. However, since there is no device to lock the steel coil after reeling, the coil is prone to loosening, which can create safety hazards and require rework and re-reeling. This makes this type of steel coil take-up reel somewhat inconvenient when reeling in steel coils. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned steel coil take-up reel is inconvenient and prone to loosening when taking up steel coils, and to provide an anti-loosening mechanism for steel coil reels.

[0006] The technical solution adopted by this utility model is as follows: A steel coil anti-loosening mechanism includes a support frame A, a lead screw slide rail, a sliding frame, a hydraulic rod, a support frame B, a servo motor, a rotating bracket, a coil frame, a groove, a slide groove A, a rotating bracket, and a stop. A lead screw slide rail is fixedly installed on the side of the support frame A. A sliding frame is slidably mounted on the side of the lead screw slide rail via a slider. A hydraulic rod is fixedly installed on the side of the sliding frame. A support frame B is fixedly installed on the side of the end of the hydraulic rod. A servo motor is fixedly installed on the side of the support frame B. The servo motor is connected to the rotating bracket via an output shaft. A coil frame is arranged on the side of the servo motor, and the coil frame is embedded on the side. The reel frame is provided with a groove, and the rotating bracket is slidably disposed inside the groove. The side of the reel frame and the side of the rotating bracket are connected by bolts. The outer ring of the reel frame has a sliding groove A embedded on both sides, and the sliding groove A is ring-shaped. The rotating bracket is slidably disposed inside the sliding groove A, and the rotating bracket is ring-shaped. The outer ring of the rotating bracket is fixedly installed with four stops, and every two stops are arranged opposite each other and symmetrically at the center. The outer side of the stops is provided with an adjusting pressing mechanism to prevent the steel coil from loosening, and a locking and anti-loosening mechanism to limit the steel coil head and prevent loosening. The outer side of the rotating bracket is provided with a rotating pressing mechanism to facilitate pressing steel coils of different lengths.

[0007] The adjusting pressing mechanism comprises a slide groove B, a sliding stop, a threaded groove A, an adjusting screw A, a support slider, a pressing frame, and a slide groove C. The slide groove B is embedded above the stop. The sliding stop is slidably mounted inside the slide groove B. A threaded groove A is embedded above the stop near the slide groove B. An adjusting screw A is rotatably mounted on the side of the sliding stop via a bearing, and the adjusting screw A is threadedly engaged and rotatably mounted inside the threaded groove A. A pressing frame is mounted above the sliding stop. The slide groove C is embedded below the pressing frame. A support slider is fixedly mounted above the sliding stop near the lower part of the pressing frame, and the slide groove C is slidably mounted on the outside of the support slider.

[0008] The rotating pressing mechanism consists of a limiting groove, a damping telescopic rod, and a limiting block. The inner wall of the slide groove A is provided with a limiting groove embedded in each other. There are several limiting grooves, which are arranged in a semi-circular shape and are equidistantly arranged. The rotating frame is fixedly installed with damping telescopic rods on all four sides, and springs are provided on the outer side of the damping telescopic rods. The end of the damping telescopic rod is fixedly installed with a limiting block, which is semi-circular and is slidably arranged inside the limiting groove.

[0009] The locking and anti-loosening mechanism consists of a clamping groove, a threaded groove B, an adjusting screw B, and a rubber pressure frame. The clamping groove is embedded on the side of the pressure frame and is arc-shaped. The threaded groove B is embedded on the upper part of the inner wall of the clamping groove. The adjusting screw B is rotatably engaged inside the threaded groove B. The rubber pressure frame is rotatably mounted below the adjusting screw B via a bearing.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. This type of anti-loosening mechanism for steel coils is equipped with an adjustable pressing mechanism. Workers can use the coordination between the slide groove B, sliding stop, threaded groove A, adjusting screw A, support slider, pressing frame, and slide groove C. The adjusting screw A rotates within the threaded groove A, causing the sliding stop to move freely up and down within the slide groove B, thus pressing the steel coil firmly. This prevents the pressed steel coil from easily loosening during subsequent transportation, thus avoiding safety hazards and improving the effectiveness of the stable pressing treatment.

[0012] 2. This type of anti-loosening mechanism for steel coils is equipped with a rotating pressing mechanism. This allows the operator to use the cooperation between the limiting groove, the damping telescopic rod, and the limiting block to drive the rotating frame to slide inside the slide groove A. The pressing limiting block is free to slide and be limited inside the limiting groove by the damping telescopic rod and the outer spring. This allows the operator to freely adjust the position of the pressing frame to achieve the effect of pressing and fixing steel coils of different lengths.

[0013] 3. This type of anti-loosening mechanism for steel coils is equipped with a locking anti-loosening mechanism. By coordinating the clamping groove, threaded groove B, adjusting screw B, and rubber pressure frame, the adjusting screw B rotates within the threaded groove B, pushing the rubber pressure frame to freely rise and fall to press and fix the end of the steel coil. This improves the effect of securely locking the steel coil and prevents the steel coil from easily becoming loose. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this utility model:

[0023] Example 1: Refer to Figure 1-5A steel coil anti-loosening mechanism includes a support frame A1, a lead screw slide rail 101, a sliding frame 102, a hydraulic rod 103, a support frame B104, a servo motor 105, a rotating bracket 106, a coil holder 2, a groove 201, a slide groove A202, a rotating bracket 3, and a stop 301. The lead screw slide rail 101 is fixedly mounted on the side of the support frame A1. The sliding frame 102 is slidably mounted on the side of the lead screw slide rail 101 via a slider. The hydraulic rod 103 is fixedly mounted on the side of the sliding frame 102. The support frame B104 is fixedly mounted on the side of the end of the hydraulic rod 103. The servo motor 105 is fixedly mounted on the side of the support frame B104. The servo motor 105 is connected to the rotating bracket 106 via an output shaft. The coil holder 2 is located on the side of the servo motor 105. The reel frame 2 has a groove 201 embedded in its side, and the rotating bracket 106 is slidably disposed inside the groove 201. The side of the reel frame 2 and the side of the rotating bracket 106 are connected by bolts. The outer ring of the reel frame 2 has a sliding groove A202 embedded in both sides, and the sliding groove A202 is ring-shaped. The rotating frame 3 is slidably disposed inside the sliding groove A202, and the rotating frame 3 is ring-shaped. The outer ring of the rotating frame 3 is fixedly installed with a stop 301. There are four stops 301, and every two are arranged opposite each other and centrally symmetrically. The outer side of the stop 301 is provided with an adjusting pressing mechanism to prevent the steel coil from loosening, and a locking and anti-loosening mechanism to limit the steel coil head and prevent loosening. The outer side of the rotating frame 3 is provided with a rotating pressing mechanism to facilitate pressing steel coils of different lengths.

[0024] Reference Figure 1-3 Furthermore, the adjusting pressing mechanism is composed of a slide groove B304, a sliding stop 305, a threaded groove A306, an adjusting screw A307, a support slider 308, a pressing frame 4, and a slide groove C405;

[0025] A sliding groove B304 is embedded above the stop 301. A sliding stop 305 is slidably mounted inside the sliding groove B304. A threaded groove A306 is embedded on the side of the stop 301 near the sliding groove B304. An adjusting screw A307 is rotatably mounted on the side of the sliding stop 305 via a bearing, and the adjusting screw A307 is threaded and rotatably mounted inside the threaded groove A306. A pressure frame 4 is mounted above the sliding stop 305, and a sliding groove C is embedded below the pressure frame 4. 405. A support slider 308 is fixedly installed above the sliding stop 305 near the lower part of the pressure frame 4, and the sliding groove C405 is slidably set on the outside of the support slider 308. When the operator needs to rewind the steel coil, the side groove 201 of the reel frame 2 is slid to the outside of the rotating bracket 106, and after the bolts are tightened between the reel frame 2 and the rotating bracket 106, the operator places one end of the steel coil to be wound on the outer ring of the reel frame 2 and pre-wound it several times. Then, the servo motor 105 is turned on. The moving coil frame 2 winds the steel coil. After the steel coil is wound, the operator turns the two opposing adjusting screws A307 into the threaded groove A306, causing them to engage and rotate. This pushes the sliding stop 305 upwards in the slide groove B304, raising the pressure frame 4. The operator then pushes the two pressure frames 4 through the slide groove C405 to slide in opposite directions on the outside of the support slider 308, approaching the outer ring of the steel coil. Then, the operator turns the two adjusting screws A307 in the opposite direction, causing them to engage and rotate. This pushes the sliding stop 305 downwards in the slide groove B304, lowering the pressure frame 4 and contacting the surface of the outer ring of the steel coil to press and limit its position. The other two pressure frames 4 are then adjusted in the same way to press and limit the outer ring of the steel coil a second time, completing the pressing and strengthening process of the steel coil. This prevents the pressed steel coil from easily loosening during subsequent transportation, thus avoiding safety hazards and improving the effectiveness of the pressing and strengthening process.

[0026] Reference Figure 2 , 3 5. Furthermore, the rotating pressing mechanism is composed of a limiting groove 203, a damping telescopic rod 302, and a limiting block 303;

[0027] A limiting groove 203 is embedded in the inner wall of the slide A202. Several limiting grooves 203 are arranged in a semi-circular, equidistant pattern. Damping telescopic rods 302 are fixedly installed around the sides of the rotating frame 3, and springs are fitted to the outer sides of the damping telescopic rods 302. Limiting blocks 303 are fixedly installed at the ends of the damping telescopic rods 302, and these blocks are semi-circular and slide within the limiting grooves 203. When the operator turns on the servo motor 105 to drive the winding reel 2 to wind the steel coil, and after the steel coil is wound, the downward pressure position of the pressure frame 4 needs to be adjusted. Pushing the baffle 301 causes the rotating frame 3 to slide inside the slide groove A202. The squeezing limit block 303 slides out of the limit groove 203, causing the damping telescopic rod 302 and the outer spring to retract. After releasing and rotating the rotating frame 3, and rotating the pressure frame 4 above the baffle 301 to a suitable pressing position, the damping telescopic rod 302 and the outer spring pop out of the limit block 303 and slide into the corresponding limit groove 203, limiting and fixing the baffle 301. The pressure frame 4 is adjusted in the same way to contact the surface of the steel coil, and the end of the steel coil is pressed and solidified. This allows the staff to freely adjust the position of the pressure frame 4 to achieve the effect of pressing and solidifying steel coils of different lengths.

[0028] Reference Figure 1-4 Furthermore, the locking and anti-loosening mechanism consists of a clamping groove 401, a threaded groove B402, an adjusting screw B403, and a rubber pressure frame 404;

[0029] The pressure frame 4 has a clamping groove 401 embedded on its side, and the clamping groove 401 is arc-shaped. A threaded groove B402 is embedded on the upper part of the inner wall of the clamping groove 401. An adjusting screw B403 is rotatably engaged with the threaded groove B402. A rubber pressure frame 404 is rotatably mounted below the adjusting screw B403 via a bearing. After the operator adjusts the four pressure frames 4 to compress the steel coil, the end of the outer ring of the steel coil is placed between the inner sides of the clamping grooves 401 of two opposite adjusting pressure frames 4. The two adjusting screws B403 are turned and rotated in the threaded grooves B402, pushing the rubber pressure frame 404 down and pressing it into contact with the end of the steel coil. After the steel coil end is squeezed and limited inside the clamping groove 401, the steel coil end is locked and the steel ring is completely fixed. Then, the operator controls the screw slide rail 101 to lower the steel coil to the surface above the support frame A1, and controls the hydraulic rod 103 to retract and rotate the bracket 106 to slide out of the groove 201 to release the coil rack 2. After the operator carries the steel coil to the designated placement site, the other steel coils that need to be wound are wound and fixed in the same way. When the operator transports several steel coils, the locked steel coil can avoid loosening during transportation and prevent safety hazards. This improves the effect of the steel coil's stable locking treatment and prevents the steel coil from easily becoming loose.

[0030] Reference Figure 1-2Furthermore, the hydraulic rod 103 is electrically connected to the battery via a matching hydraulic pump and a matching control panel, and the lead screw slide rail 101 and the servo motor 105 are both electrically connected to the battery via matching control panels. Example

[0031] like Figure 5 , 6 As shown, in one embodiment of this invention, a limiting groove 203 is embedded in the inner wall of the slide groove A202, and there are several limiting grooves 203 arranged in a semi-circular, equidistant manner. A damping telescopic rod 302 is fixedly installed around the sides of the rotating frame 3, and a spring is fitted to the outer side of each damping telescopic rod 302. A limiting block 303 is fixedly installed at the end of each damping telescopic rod 302, and the limiting block 303 is semi-circular and slides within the limiting groove 203. In another embodiment, a limiting groove 203 is embedded in the inner wall of the slide groove A202, and there are several limiting grooves 203 arranged in a semi-circular manner. The inner walls of the limiting grooves 203 are relatively inclined. A damping telescopic rod 302 is fixedly installed around the sides of the rotating frame 3, and a spring is fitted to the outer side of each damping telescopic rod 302. A limiting block 303 is fixedly installed on the side of the end of the damping telescopic rod 302. The limiting block 303 is set with a relatively inclined shape around its perimeter and is slidably fitted inside the limiting groove 203. When the operator pushes the stop frame 301 to drive the rotating frame 3 to slide inside the slide groove A202, the limiting block 303 is squeezed out of the limiting groove 203, causing the damping telescopic rod 302 and the outer spring to contract. After the rotating frame 3 is released and the pressure frame 4 above the stop frame 301 is rotated to a suitable downward pressing position, the damping telescopic rod 302 and the outer spring pop out and slide into the relatively inclined limiting block 303 on the inner wall of the corresponding relatively inclined limiting groove 203. This will result in a larger contact area between the limiting block 303 and the limiting groove 203, generating greater friction and more firmly limiting and fixing the stop frame 301. Compared with the first embodiment, the limiting and fixing effect is better.

[0032] Working principle: First, when the operator needs to rewind the steel coil, the side groove 201 of the coil frame 2 is slid to the outside of the rotating bracket 106. After the bolts are tightened between the coil frame 2 and the rotating bracket 106, the operator places one end of the steel ring to be wound on the outer ring of the coil frame 2 and pre-wound it several times. Then, the servo motor 105 is turned on to drive the coil frame 2 to wind the steel ring. After the steel coil is wound, when it is necessary to adjust the downward pressure position of the pressure frame 4, the stop frame 301 is pushed to drive the rotating bracket 3 to slide inside the slide groove A202. The pressure limit block 303 slides out of the limit groove 203, causing the damping telescopic rod 302 and the outer spring to retract. After loosening and rotating the rotating frame 3 and rotating the pressure frame 4 above the stop frame 301 to the appropriate downward pressing position, the damping telescopic rod 302 and the outer spring pop out the limiting block 303 and slide into the inner side of the corresponding limiting groove 203, limiting and fixing the stop frame 301. Then, the operator turns the two opposing adjusting screws A307 into the threaded engagement inside the threaded groove A306, pushing the sliding stop frame 305 to slide upward inside the slide groove B304, causing the pressure frame 4 to rise. Then, the operator pushes the two pressure frames 4 through the slide groove C405 to slide in opposite directions outside the support slider 308. After approaching the outer ring of the steel coil, the two adjusting screws are turned in the opposite direction. Screw A307 rotates within the threaded groove A306, pushing sliding stop 305 downwards within the sliding groove B304, causing pressure frame 4 to descend and contact the outer surface of the steel coil, thus pressing and limiting the steel coil. The other two pressure frames 4 are then adjusted in the same manner to perform a second pressing and limiting of the outer coil, completing the pressing process. Finally, the worker places the end of the outer coil between the side clamping grooves 401 of two opposing adjusting pressure frames 4 and rotates the two adjusting screws B403 within the threaded groove B402, pushing the rubber pressure frame 40... 4. After lowering and pressing the surface of the steel coil end, and pressing and limiting the steel coil end inside the clamping groove 401, the steel coil end is locked. After the steel ring is completely fixed, the worker controls the screw slide rail 101 to lower the steel coil to the surface above the support frame A1, and controls the hydraulic rod 103 to retract and rotate the bracket 106 to slide out of the groove 201 to release the coil frame 2. After the worker carries the steel coil to the designated placement site, the other steel coils that need to be wound are wound and fixed in the same way. When the worker transports several steel coils, the locked steel coils can avoid loosening during transportation and causing safety hazards.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
