Description

Technical Field

[0001] The invention relates to the field of steel conveying equipment, and in particular to a deviation correction and protection component for steel conveying. Background Art

[0002] In the field of steel processing and transportation, C-shaped steel is often transported in the form of stacking through conveyor chains so that it can be moved to the bundling station for subsequent processing, such as Figure 8 As shown in the figure, the C-shaped steel stack is composed of multiple layers, and each layer is made up of C-shaped steels arranged with openings up and down. The layers are naturally pressed together by gravity. Although this stacking method can improve space utilization, it is easy to cause displacement due to external interference during transportation due to the open characteristics of the C-shaped steel structure itself and the instability of the contact surface between layers.

[0003] However, the existing conveyor chain plates often cause mechanical vibration, unstable transmission and other problems during operation, resulting in the C-shaped steel stack being misaligned in the front-to-back or left-to-right direction during transportation. At the same time, due to the uneven distribution of gravity on each layer of C-shaped steel, the traditional alignment method requires a large supporting force to achieve correction, and the supporting force is concentrated on the front and rear edges of the C-shaped steel stack. Due to the low edge strength of the open structure of the C-shaped steel, local deformation is prone to occur under a large thrust, especially the open side of the thin-walled C-shaped steel is prone to damage.

[0004] In addition, the simple one-sided abutment alignment method in the existing technology causes the one-way thrust of the front and rear sides to clamp and act on the C-steel stack at the same time, which makes it difficult to make fine adjustments to the front and rear misalignment of each layer of C-steel, and the method of clamping and abutting the C-steel stack can only move the C-steel to a flush position and then stop. Since the C-steel itself will be slightly deformed when clamped, the C-steel stack is still in an uneven state after the clamping force is removed, resulting in poor alignment effect, and during abutment alignment, since the upper and lower adjacent C-steels in the C-steel stack are close to each other, when adjusting the front and rear misaligned C-steels, it is necessary to overcome the friction between the C-steels, and it is difficult to achieve rapid correction with low force.

[0005] Therefore, there is an urgent need for a protective component that can take into account low force, reduce the impact of C-shaped steel deformation, and perform multi-directional correction and alignment of multiple C-shaped steels after stacking, so as to solve the above technical problems.

[0011] Preferably, the uppermost and lowermost slot plate frames are hinged with connecting plates on one side away from the middle of the sliding frame, and the remaining slot plate frames are hinged with synchronous plates on one side away from the middle of the sliding frame. The connecting plates and the synchronous plates are connected end to end to form a one-way continuous structure.

[0013] Preferably, each group of the insert blocks consists of two insert blocks that are symmetrically arranged front to back, and the upper sides and the sides away from each other of the insert blocks in the same group are rotatably provided with abutment rollers.

[0014] Preferably, two sliding plates arranged up and down are provided inside the slot plate frame for sliding back and forth, the upper sliding plate is fixedly connected to a plug block located at the front in each group of plug blocks in the same slot plate frame, and the lower sliding plate is fixedly connected to a plug block located at the rear in each group of plug blocks in the same slot plate frame.

[0015] Preferably, the two sliding plates inside the same slotted plate frame are fixedly connected to a linkage rack on one side close to each other, and a plurality of linkage gears arranged front and back are rotatably provided inside the slotted plate frame, and the linkage gears are engaged with the linkage racks on the upper and lower sides thereof.

[0016] Preferably, an active plate is provided on the front side of the flip frame for sliding back and forth, and a sliding plate at the upper part of the slotted plate frame at the corresponding position of the active plate is slidably connected along the length direction of the flip frame, and an electric cylinder for driving the active plate is provided on the flip frame.

[0017] Preferably, the driving part includes two U-shaped frames that are slidably arranged on the guide rail frame legs and are symmetrically distributed front to back. A linkage shaft is rotatably arranged on one side of the U-shaped frame close to the middle of the guide rail frame, and the linkage shaft is fixedly connected to the eccentric position of a group of eccentric wheels at the corresponding position.

[0018] Preferably, a driven gear is fixedly installed on the upper side of the linkage shaft, and two fixed racks symmetrically arranged front and back are fixedly installed on the lower side of the sliding frame. The fixed racks are provided with toothless notches at equal intervals along the left and right directions. A trapezoidal plate is fixedly installed at the position corresponding to the fixed rack notch on the sliding frame, and a semicircular groove is provided at the upper end of the linkage shaft.

[0019] The beneficial effects of the present invention are: 1. The present invention adopts an insert block to be inserted into the interior of the C-shaped steel with the opening facing downward, and the C-shaped steel stack is supported in layers by the equidistant lifting action of the slot plate frame, and the left and right sides of the slot plate frame are used to support the C-shaped steel stack to the left and right, so as to achieve left and right alignment under low force in a layered adjustment manner, and the eccentric wheel is driven by the driving part to perform layered front and back support on the C-shaped steel stack, thereby avoiding the deformation damage to the opening edge of the C-shaped steel caused by the traditional unilateral concentrated support.

[0020] 2. The present invention adopts a driving part to drive two sets of eccentric wheels to actively push the C-shaped steel stack back and forth. Through the rotation of the eccentric wheel, each layer of C-shaped steel produces periodic displacement in the front and rear directions, and uses dynamic movement to adjust the front and rear misalignment, effectively preventing the C-shaped steel from being not pushed into place due to deformation, realizing fine adjustment of the front and rear alignment, significantly reducing the external force required for alignment and improving the quality of correction.

[0021] 3. The present invention adopts a front-to-back symmetrical arrangement of each group of inserts and an internal support clamping design of the abutment roller. Through the synchronous drive of the sliding plate and the linkage gear, the inserts are expanded or contracted in the front-to-back direction, forming a uniform supporting force on the inner wall of the C-shaped steel, which not only enhances the alignment quality, but also avoids the secondary misalignment problem caused by elastic deformation after the external force is removed.

[0022] 4. The present invention adopts the intermittent cooperation between the trapezoidal plate and the semicircular groove on the linkage shaft, and controls the eccentric wheel to stop rotating and lock at a certain angle through the intermittent engagement of the fixed rack and the driven gear. The C-shaped steel stack is driven to the left by the push of the conveying chain plate and the left groove plate frame, so that the stopped eccentric wheel pulls the C-shaped steel stack to the left under the action of friction and presses against the left groove plate frame, thereby further improving the overall flatness of the C-shaped steel stack.

[0034] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0035] See Figure 1 and Figure 2A deviation correction and protection component for steel transportation includes a guide rail frame 1, a sliding frame 2 is provided on the guide rail frame 1 for sliding left and right, and a positioning unit 3 is provided on the sliding frame 2 for aligning the C-shaped steel left and right by abutting layer by layer. The guide rail frame 1 and the sliding frame 2 are jointly provided with a leveling unit 4 for pushing the C-shaped steel forward and backward to align.

[0036] It should be noted that the guide rail frame 1 consists of legs and a cross frame. The legs are fixedly connected to the ground, and the cross frame is fixedly connected to the upper ends of the legs. The sliding frame 2 is driven by the existing slide rail power assembly to move left and right on the cross frame of the guide rail frame 1.

[0037] When the C-shaped steel needs to be transported, the stacked C-shaped steel pile is first transported to the right by the existing chain conveyor, and then the slide rail power assembly drives the slide frame 2 to move synchronously with the C-shaped steel pile. During the movement, Figure 8 As shown, the C-shaped steel stack is lifted layer by layer by the alignment unit 3, and the left and right ends of the C-shaped steel stack are aligned. At the same time, the front and rear sides of the C-shaped steel stack are dynamically aligned by the leveling unit 4 by a back and forth pushing method.

[0038] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The alignment unit 3 includes two symmetrically arranged flip frames 31 hinged on the left and right sides of the sliding frame 2 respectively. A plurality of equally spaced slotted plates 32 are provided on one side of the flip frame 31 close to the middle of the sliding frame 2 for sliding along the length direction of the flip frame 31. A plurality of groups of plug blocks 33 for supporting and externally supporting C-shaped steel are provided on one side of the slotted plates 32 close to the middle of the sliding frame 2 for sliding along the front-to-back direction.

[0039] See Figure 1 and Figure 3 The sliding frame 2 is hinged with two hydraulic cylinders 21 arranged symmetrically on the left and right, and the telescopic sections of the hydraulic cylinders 21 are hinged with the turning frames 31 at corresponding positions.

[0040] In the initial state, the telescopic section of the left hydraulic cylinder 21 is in an extended state, so that the left hydraulic cylinder 21 pushes the lower side of the left flip frame 31 to flip away from the middle of the sliding frame 2, and the telescopic section of the right hydraulic cylinder 21 is in a retracted state, so that the right hydraulic cylinder 21 pulls the right flip frame 31 to a vertical state, thereby facilitating the chain conveyor to transport the C-shaped steel stack to the lower part of the sliding frame 2.

[0041] When the chain conveyor transports the C-shaped steel stack to the lower part of the sliding frame 2 to the right, the right side of the C-shaped steel stack moving to the right moves to abut against the left side of the right slot frame 32. At this time, each group of plugs 33 on the right slot frame 32 is correspondingly inserted into the interior of a C-shaped steel with an opening facing downward. Then, the sliding frame 2 is driven to move synchronously to the left together with the C-shaped steel stack through the slide rail power assembly, and the telescopic section of the left hydraulic cylinder 21 is retracted, so that the left flip frame 31 drives each group of plugs 33 on the left to also be inserted into the interior of a corresponding C-shaped steel with an opening facing downward.

[0042] It should be noted that when the insert block 33 on the lowest slot plate frame 32 on the left flip frame 31 is inserted into the interior of the C-shaped steel, the left flip frame 31 has not yet been completely flipped to a vertical state, so that the left flip frame 31 drives the slot plate frame 32 thereon not to contact the left side of the C-shaped steel stack, but the insert blocks 33 at the left flip frame 31 are all inserted into the interior of the C-shaped steel.

[0043] In order to make all the slotted plate racks 32 on the same turning rack 31 to be arranged at equal intervals so that the slotted plate racks 32 can lift the C-shaped steel stacks layer by layer through the inserts 33, the following design is made: Figure 2 The uppermost and lowermost slot plate frames 32 are hingedly connected to a connecting plate 321 on one side away from the middle of the sliding frame 2, and the remaining slot plate frames 32 are hingedly connected to a synchronous plate 322 on one side away from the middle of the sliding frame 2. The connecting plate 321 and the synchronous plate 322 are hinged end to end to form a one-way continuous structure.

[0044] By connecting the end to end of the connecting plate 321 and the synchronous plate 322, all the slot plate frames 32 on the same turning frame 31 are connected to each other. When the position of the lowest slot plate frame 32 is locked, the uppermost slot plate frame 32 is moved so that the uppermost slot plate frame 32 pulls the synchronous plate 322 to rotate through the connecting plate 321 thereon, so that the synchronous plate 322 rotates and pushes the middle slot plate frame 32 to move at equal intervals, thereby making the distance between two adjacent slot plate frames 32 on the same turning frame 31 always consistent.

[0045] See Figure 2 、 Figure 3 and Figure 4 The guide rod 323 is fixedly installed on the side of the lowermost slot plate frame 32 away from the middle of the sliding frame 2, and a movable square rod 324 is slidingly provided in the middle of the flip frame 31 along its length direction. A coil spring is provided between the upper side of the movable square rod 324 and the upper end of the guide rod 323. The movable square rod 324 is fixedly connected to the uppermost slot plate frame 32, and a hydraulic push rod 325 is provided between the movable square rod 324 and the flip frame 31.

[0046] See Figure 4Each group of insert blocks 33 is composed of two insert blocks 33 arranged symmetrically in front and back, and the upper side and the side away from each other of the insert blocks 33 in the same group are rotatably provided with abutting rollers 331.

[0047] It should be noted that the spacing between the two adjacent slotted plate frames 32 above and below corresponds to the height of each layer of the C-shaped steel stack, so that after the slotted plate frame 32 drives the plug 33 to be inserted into the interior of the C-shaped steel, the two plugs 33 in the same group correspond to the middle position of the C-shaped steel, so that when the two plugs 33 in the same group are subsequently moved away from each other synchronously, the C-shaped steel can be internally supported and the position of the C-shaped steel can be locked.

[0048] When the insert block 33 at the left flip frame 31 is inserted into the interior of the C-shaped steel, the telescopic sections of the left and right hydraulic push rods 325 are simultaneously contracted, so that the hydraulic push rods 325 drive the movable square rod 324 at the corresponding position to move upward along the length direction of the corresponding flip frame 31. The movable square rod 324 drives the guide rod 323 to move upward synchronously through the coil spring, and the guide rod 323 drives the lowest slot plate frame 32 to move upward synchronously.

[0049] At the same time, the moving square rod 324 directly drives the uppermost slot plate rack 32 to move upward. Since the uppermost and lowermost slot plate racks 32 on the same turning frame 31 move upward synchronously, the spacing between the slot plate racks 32 on the same turning frame 31 remains unchanged and all move upward. Figure 8 and Figure 9 As shown, when the slot plate frame 32 drives the outer side of the abutting roller 331 located on the upper part of the insert block 33 thereof to abut against the lower side of the horizontal section of the corresponding C-shaped steel, the slot plate frame 32 continues to move upward, so that the slot plate frame 32 lifts the C-shaped steel at the corresponding position through the insert block 33 until the upper end of the guide rod 323 abuts against the flip frame 31.

[0050] Then, the telescopic section of the hydraulic push rod 325 is further retracted. Since the guide rod 323 is blocked by the flip frame 31 and cannot move upward, the lowest slot plate frame 32 cannot move upward. As a result, the movable square rod 324 drives the uppermost slot plate frame 32 to move upward relative to the lowermost slot plate frame 32 and compresses the coil spring, thereby gradually increasing the distance between the two adjacent slot plate frames 32 above and below. The slot plate frames 32 push the C-shaped steel stacks to be arranged in layers through the insert blocks 33.

[0051] It should be noted that if Figure 8 and Figure 9 As shown, the C-shaped steel at the bottom layer of the layered C-shaped steel stack is composed of several C-shaped steels arranged front and back with openings facing upward, the C-shaped steel at the top layer is composed of several C-shaped steels arranged front and back with openings facing downward, and the C-shaped steels in the remaining layers are composed of several horizontal sections of C-shaped steels with openings facing upward and C-shaped steels with openings facing downward that are bonded together and arranged front and back.

[0052] Then, the telescopic section of the left hydraulic cylinder 21 is fully retracted, so that the left flip frame 31 rotates to a vertical state, so that the left slot plate frame 32 abuts against the left side surface of the layered C-shaped steel stack, and then the layered C-shaped steel stack is smoothly moved left and right to be aligned left and right through the slot plate frames 32 on the left and right flip frames 31.

[0053] See Figure 1 、 Figure 2 、 Figure 4 and Figure 6 The leveling unit 4 includes a driving part 41 that is jointly provided on the guide rail frame 1 and the sliding frame 2. The driving part 41 is provided with two sets of eccentric wheels 42 arranged front to back and used to push the C-shaped steel stack forward and backward. By inserting the plug block 33 with the opening facing downward into the C-shaped steel, the C-shaped steel stack is arranged in layers up and down, so that the slot plate frame 32 and the eccentric wheel 42 can smoothly push the C-shaped steel stack to be aligned left to right and front to back.

[0054] See Figure 1 、 Figure 2 and Figure 6 The driving part 41 includes two U-shaped frames 411 that are slidably arranged on the legs of the guide rail frame 1 and are symmetrically distributed front to back. A linkage shaft 412 is rotatably arranged on one side of the U-shaped frame 411 close to the middle of the guide rail frame 1. The linkage shaft 412 is fixedly connected to the eccentric position of a group of eccentric wheels 42 at the corresponding position. Each group of eccentric wheels 42 is composed of several eccentric wheels 42 arranged at equal intervals above and below.

[0055] See Figure 2 、 Figure 6 and Figure 7 A driven gear 413 is fixedly installed on the upper side of the linkage shaft 412, and two fixed racks 414 are fixedly installed on the lower side of the sliding frame 2, which are symmetrically arranged in the front and rear directions. The fixed racks 414 are provided with toothless notches at equal intervals along the left and right directions. A trapezoidal plate 415 is fixedly installed on the sliding frame 2 at the position corresponding to the notch of the fixed rack 414, and a semicircular groove is provided on the upper end of the linkage shaft 412.

[0056] It should be noted that if Figure 2 、 Figure 6 and Figure 7 As shown, electric push rods 416 are fixedly installed on the front and rear legs, and the telescopic section of the electric push rod 416 is fixedly connected to the U-shaped frame 411 at the corresponding position. The outer side of the linkage shaft 412 and the lower part of the driven gear 413 are in a straight surface structure. A locking piece 417 is fixedly installed on the side surface where the front and rear legs are close to each other, and the middle part of the locking piece 417 is a slot structure for locking on the straight surface structure of the linkage shaft 412.

[0057] In the initial state, the two U-shaped frames 411 are away from each other, and the straight surface structure of the linkage shaft 412 is fitted on the inner side surface of the slot structure of the locking member 417. The locking member 417 blocks the linkage shaft 412 to prevent the linkage shaft 412 from rotating. At this time, the pushing range of the front eccentric wheel 42 is toward the right, and the pushing range of the rear eccentric wheel 42 is toward the left.

[0058] When the C-shaped steel stack moves to the right between the two sets of eccentric wheels 42, the telescopic sections of the front and rear electric push rods 416 are extended at the same time, so that the front and rear U-shaped frames 411 drive the cylindrical surfaces of the two sets of eccentric wheels 42 to press against the front and rear side surfaces of the C-shaped steel stack through the linkage shaft 412, and the two front and rear eccentric wheels 42 at the same height press against the front and rear side surfaces of the corresponding layer of C-shaped steel.

[0059] When the eccentric wheel 42 rests on the C-shaped steel, the linkage shaft 412 moves to a position where it does not contact the locking member 417. At the same time, the linkage shaft 412 drives the driven gear 413 thereon to move to engage with the fixed rack 414. Then the sliding frame 2 continues to move to the right with the C-shaped steel stack, so that the sliding frame 2 drives the linkage shaft 412 to rotate through the engagement of the fixed rack 414 with the driven gear 413. The linkage shaft 412 drives a group of eccentric wheels 42 thereon to rotate, so that the two groups of eccentric wheels 42 rotate synchronously in opposite directions.

[0060] While the two sets of eccentric wheels 42 rotate, they push the layered C-shaped steels back and forth, causing each layer of C-shaped steel to produce periodic displacement in the front-to-back direction. The front-to-back misalignment is adjusted by dynamic movement, effectively preventing the C-shaped steels from being pushed into place due to deformation, and achieving fine adjustment of the front-to-back alignment.

[0061] When the sliding frame 2 drives the toothless notch on the fixed rack 414 to move to the position of the driven gear 413, the driven gear 413 stops rotating and is at the initial angle, and at this time the linkage shaft 412 rotates until the vertical surface of its upper semicircular groove faces the middle of the sliding frame 2, so that the sliding frame 2 drives the trapezoidal plate 415 to move away from the side of the middle of the sliding frame 2 and fits onto the vertical surface of the semicircular groove of the linkage shaft 412, thereby locking the rotation angle of the linkage shaft 412, and using the conveying chain plate and the left slot plate frame 32 to continuously drive the C-shaped steel stack to move to the right, and the eccentric wheel 42 pulls the C-shaped steel stack to the left under the action of friction and presses against the left slot plate frame 32, further improving the overall flatness of the C-shaped steel stack.

[0062] See Figure 4 、 Figure 5 and Figure 9Two sliding plates 332 arranged up and down are provided inside the slot plate frame 32 for sliding back and forth. The upper sliding plate 332 is fixedly connected to a front plug-in block 33 in each group of plug-in blocks 33 in the same slot plate frame 32, and the lower sliding plate 332 is fixedly connected to a rear plug-in block 33 in each group of plug-in blocks 33 in the same slot plate frame 32.

[0063] See Figure 5 The two sliding plates 332 inside the same slot frame 32 are fixedly connected to the side close to each other with a linkage rack 333. A number of linkage gears 334 arranged front and back are rotatably set inside the slot frame 32, and the linkage gears 334 are engaged with the linkage racks 333 on the upper and lower sides thereof.

[0064] See Figure 2 、 Figure 3 and Figure 4 An active plate 335 is provided on the front side of the flip frame 31 for sliding back and forth. The active plate 335 is slidably connected to the upper sliding plate 332 in the corresponding position of the slot plate frame 32 along the length direction of the flip frame 31. An electric cylinder 336 is provided on the flip frame 31 to drive the active plate 335.

[0065] When the linkage rack 333 moves to the position of the linkage shaft 412 of the trapezoidal plate 415 on the far left, the two sets of eccentric wheels 42 rotate to the initial angle, and then the telescopic sections of the two electric push rods 416 are retracted, so that the two sets of eccentric wheels 42 move to the initial position, and at the same time, the telescopic sections of the two electric cylinders 336 are extended, so that the electric cylinders 336 drive the active plates 335 at the corresponding positions to move forward, and the active plates 335 drive the upper sliding plates 332 in the same slot plate frame 32 to move forward. At the same time, the upper sliding plates 332 in the same slot plate frame 32 drive the linkage rack 333 thereon to move forward synchronously, and the linkage rack 333 drives the lower sliding plates 332 in the same slot plate frame 32 to move backward synchronously through the linkage gear 334.

[0066] like Figure 8 and Figure 9 As shown, the sliding plate 332 drives the two plug blocks 33 in the same group to move in opposite directions, and then the two plug blocks 33 in the same group drive the side abutment rollers 331 to abut against the horizontal section of the C-shaped steel through internal support. At this time, the two C-shaped steels with opposite opening directions are still in an overlapping state, so that the two plug blocks 33 in the same group push a vertical section of the C-shaped steel with an upward opening and a vertical section of the C-shaped steel with a downward opening, so that the two overlapping C-shaped steels with opposite opening directions are tightly pressed together.

[0067] like Figure 8 and Figure 9As shown, since the vertical sections of the C-shaped steels at the same height are close together, the vertical sections of the two C-shaped steels close together are located between the two vertical sections of an upper or lower C-shaped steel. This allows the C-shaped steels with overlapping vertical sections to be pushed close together when the vertical sections of the C-shaped steels are pushed by the internal support. The inserts 33 arranged in a matrix on the same flip frame 31 are then used to form a uniform support force on the inner wall of the C-shaped steel, thereby enhancing the alignment quality. The internal support of the inner wall of the C-shaped steel avoids the secondary misalignment problem caused by elastic deformation after the extrusion pressure of the eccentric wheel 42 is removed.

[0068] Then, the hydraulic push rod 325 is extended to drive the layered C-shaped steel stack to move to its initial overall state. When the C-shaped steel stack moves to the bundling station, the telescopic section of the electric cylinder 336 is retracted, and then the two turning frames 31 are flipped to be completely located on the upper part of the C-shaped steel stack, and then the sliding frame 2 is moved to the initial position, and then the right turning frame 31 is flipped to the vertical initial state.

[0069] See Figures 1 to 9 When transporting the C-shaped steel stack, the present invention also includes the following steps: First, the stacked C-shaped steel stack is transported to the right to the lower part of the sliding frame 2 by the existing chain conveyor, and the sliding frame 2 is driven to move synchronously with the C-shaped steel stack, and the telescopic section of the left hydraulic cylinder 21 is retracted, so that the left flip frame 31 drives each group of inserts 33 on the left to also be inserted into the interior of a corresponding C-shaped steel with the opening facing downward.

[0070] In the second step, the telescopic section of the hydraulic push rod 325 is retracted so that the spacing between the slotted plate racks 32 remains unchanged and all of them move upward. Then, the slotted plate racks 32 lift the C-shaped steel at the corresponding position through the insert block 33. Then, the upper end of the guide rod 323 abuts against the flip frame 31, causing the uppermost slotted plate rack 32 to move upward relative to the lowermost slotted plate rack 32, thereby causing the insert block 33 to push the C-shaped steel stacks to be arranged in layers.

[0071] The third step is to fully retract the telescopic section of the left hydraulic cylinder 21 so that the left flip frame 31 rotates to a vertical state, so that the groove plate frame 32 on the left side abuts against the left side surface of the layered C-shaped steel stack, and then the layered C-shaped steel stack is smoothly moved left and right to be aligned left and right through the groove plate frames 32 on the left and right flip frames 31.

[0072] In the fourth step, the C-shaped steel stack moves to the right between the two sets of eccentric wheels 42, and the telescopic sections of the two electric push rods 416 are extended so that the eccentric wheels 42 rest against the C-shaped steel. The sliding frame 2 drives the two sets of eccentric wheels 42 to rotate through the fixed rack 414 and pushes the layered C-shaped steel back and forth to move back and forth, dynamically moving to adjust the front and back misalignment.

[0073] In the fifth step, the sliding frame 2 drives the toothless notch on the fixed rack 414 to move to the position of the driven gear 413. The driven gear 413 stops rotating and is located at the initial angle. The conveying chain plate and the left groove plate frame 32 are used to continuously drive the C-shaped steel stack to move to the right. Under the action of friction, the eccentric wheel 42 pulls the C-shaped steel stack to the left and presses against the left groove plate frame 32, further improving the overall flatness of the C-shaped steel stack.

[0074] In the sixth step, the eccentric wheel 42 is moved to the initial position, and the telescopic section of the electric cylinder 336 is extended, so that the two plug blocks 33 in the same group drive the side abutment rollers 331 to abut against the horizontal section of the C-shaped steel through internal support, so that the vertical sections of the C-shaped steel overlapping each other are arranged closely together, and then the plug blocks 33 arranged in a matrix on the same turning frame 31 are used to form a uniform support force on the inner wall of the C-shaped steel, thereby enhancing the alignment quality and avoiding the secondary misalignment problem caused by elastic deformation after the external force is removed.

[0075] In the seventh step, the hydraulic push rod 325 is extended to move the layered C-shaped steel stack to its initial overall state. The C-shaped steel stack is moved to the bundling station, the telescopic section of the electric cylinder 336 is retracted, and then the two flip frames 31 are flipped to be completely located on the upper part of the C-shaped steel stack, and then the sliding frame 2 is moved to the initial position, and then the flip frame 31 on the right is flipped to the vertical initial state.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
