Description

Technical Field

[0001] The invention relates to the technical field of steel bar feeding, in particular to an anti-slip device for steel material transportation. Background Art

[0002] During the processing of steel bars, loading and conveying equipment is needed to load the whole bundles of scattered steel bars transported by the conveying mechanism one by one for processing. The loading and conveying equipment pushes the steel bars upward step by step through a step-by-step transmission method, so as to achieve the purpose of loading the steel bars one by one.

[0003] However, the existing feeding and conveying equipment has the following problems: 1. The steel bars are easy to slip. Since the steel bars are not bound after the whole bundle of steel bars are spread out, the steel bars are transported to the feeding position of the feeding and conveying equipment. Since the feeding and conveying equipment is a step-by-step staggered loading method, the width of the steps is usually fixed. When the diameter of the loading steel bar is much smaller than the width of the loading step, multiple steel bars will be placed on one step during loading, causing the steel bars to easily slip from the step during the loading process. In the process of sliding, they may also touch the steel bars on other steps, causing the steel bars on other steps to slide together; 2. Since the transported steel bars are long, the staggered placement of the steel bars is unstable. When the whole bundle of steel bars is loaded one by one, the steel bars are easily placed on different steps at the head and tail. As the loading and conveying continues, they are prone to falling.

[0004] Therefore, the present invention provides an anti-slip device for steel transportation, which solves the above technical problems. Summary of the Invention

[0033] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1As shown, an anti-slip device for steel transportation includes a support frame 1, a connecting slide rail 2 and a driving mechanism 3. The number of connecting slide rails 2 is multiple and evenly distributed on the left side of the support frame 1. The connecting slide rail 2 and the support frame 1 are jointly provided with an anti-slip mechanism 4 for preventing the steel bars from slipping when loading the steel bars. The driving mechanism 3 for driving the anti-slip mechanism 4 to move is provided at the bottom left end of the support frame 1.

[0035] like Figure 1 and Figure 2 As shown, the anti-slip mechanism 4 includes a movable step plate 41 that is slidably connected to the connecting slide rail 2 along the up and down directions through a connecting frame, and a fixed step plate 42 is fixedly connected to the left side of the support frame 1 and the rear side of the movable step plate 41. The movable step plate 41 is provided with a limiting member 43 for blocking the loading of steel bars, and the fixed step plate 42 is provided with an adjusting member 44 for adjusting the width of the steel bar placement position. A positioning member 45 for preventing the steel bars on the adjusting member 44 from slipping is provided between the opposite surfaces of the movable step plate 41 and the fixed step plate 42 that are close to each other.

[0036] like Figure 1 and Figure 2 As shown, the limiting member 43 includes an inverted V-shaped bracket 432 arranged on the movable step plate 41 for limiting the steel bars during the loading process, the adjusting member 44 includes an adjusting inclined plate 441 arranged on the fixed step plate 42 for adjusting the loading width of the fixed step plate 42, and the positioning member 45 includes a positioning bar 454 arranged on the fixed step plate 42 for limiting the steel bars on the fixed step plate 42. The top of the positioning bar 454 is provided with an inclined surface to prevent the positioning bar 454 from being stuck with the steel bars when rising, and the inclined surface is higher on the left and lower on the right.

[0037] like Figure 1 and Figure 3 As shown, the driving mechanism 3 includes a plurality of support plates 31 fixedly connected to the left side of the support frame 1, and a transmission shaft 32 is connected to the plurality of support plates 31 for rotation. An external driving motor drives the transmission shaft 32 to rotate on the support plate 31, and a plurality of eccentrically fixedly connected push disks 33 are evenly distributed on the plurality of transmission shafts 32. A linkage plate 35 is fixedly connected to the connecting frame of the plurality of movable step plates 41, and a push leg 34 is fixedly connected to the position of the push disk 33 on the left side of the linkage plate 35. The bottom end of the push leg 34 is provided with an auxiliary roller for changing the sliding friction between the push leg 34 and the push disk 33 into rolling friction.

[0038] During specific use, first adjust the limit position of the steel bars on each step of the movable step plate 41 when loading the material through the limit piece 43 according to the size of the steel bars, and then adjust the width of the steel bar placement position on each step of the fixed step plate 42 through the adjustment piece 44. After the adjustment is completed, the external conveying equipment conveys the whole bundle of scattered steel bars from left to right to the position near the bottom of the movable step plate 41 and the fixed step plate 42. At this time, the external drive motor drives the transmission shaft 32 to rotate on the support plate 31, and drives the push plate 33 to rotate synchronously. Since the push plate 33 and the transmission shaft 32 are eccentrically connected, when the transmission shaft 32 drives the push plate 33 to rotate, the push plate 33 pushes the push leg 34 to move back and forth up and down.

[0039] The pushing leg 34 drives multiple movable step plates 41 to move back and forth in the up and down directions on the connecting slide rail 2 through the linkage plate 35 to start loading the whole bundle of scattered steel bars on the external conveying equipment at the bottom end one by one. During the loading process, the inverted V-shaped bracket 432 is set to reduce the contact surface with the steel bars during the loading process, making it easier to support the steel bars on the step. After support, the steel bars can cooperate with the right bevel of the inverted V-shaped bracket 432 to quickly slide onto the step. At the same time, the steel bars on the step can be limited to ensure that the movable step plate 41 does not slide during the loading process of the steel bars.

[0040] After the movable step plate 41 pushes the steel bars upward and places them on the fixed step plate 42, the placement width of the steel bars on the steps of the fixed step plate 42 is adjusted by adjusting the inclined plate 441, so as to avoid placing multiple steel bars on the first step of the fixed step plate 42, thereby avoiding the situation where multiple steel bars are placed unstably and cause the steel bars to slip during the continuous loading process. At the same time, when the movable step plate 41 moves downward to load new steel bars, the positioning bar 454 moves upward and its top end exceeds the horizontal plane of the steps of the fixed step plate 42, so that the steps of the fixed step plate 42 are in a closed state, so that the movable step plate 41 limits the steel bars placed on the fixed step plate 42 during the downward movement.

[0041] like Figure 2 、 Figure 4 and Figure 5 As shown, the limiting member 43 also includes a limiting groove 433 opened on the upper surface of the step of the movable step plate 41. The interior of the limiting groove 433 is connected to a displacement slider 434 that slides along the left and right directions. An inverted V-shaped bracket 432 is hinged on the displacement slider 434. The top ends of the two oblique sides of the inverted V-shaped bracket 432 are hinged, and the left oblique side of the inverted V-shaped bracket 432 is hinged to the movable step plate 41.

[0042] like Figure 2 、 Figure 4 and Figure 5As shown, the limit member 43 also includes a stepped connecting rod 431 slidably connected to the front surface of the movable step plate 41 through a plurality of limit sleeves, and the top end of the front surface of the stepped connecting rod 431 is threadedly connected with a plurality of limit bolts for limiting the position of the stepped connecting rod 431 on the movable step plate 41. The shape of the stepped connecting rod 431 is adapted to the step shape on the left side of the movable step plate 41, and a through groove is provided on the front surface of the step position of the movable step plate 41 corresponding to the position of the displacement slider 434. The rear surface of the stepped connecting rod 431 is fixedly connected to the front surface of the displacement slider 434 through a connecting piece passing through the through groove.

[0043] Specifically, when adjusting the restricted position of the steel bars on each step of the movable step plate 41 through the limit piece 43 according to the size of the steel bars when loading, first cancel the limit of the pair of stepped connecting rods 431 on the movable step plate 41 by the limit bolts, and then the staff pulls the stepped connecting rod 431 to slide on the limiting sliding sleeve, driving the displacement slider 434 to slide to the left inside the limiting sliding groove 433. At this time, the displacement slider 434 pushes the right bevel of the inverted V-shaped bracket 432 to approach the left bevel. Moreover, since the two bevels of the inverted V-shaped bracket 432 are hinged, and the left bevel of the inverted V-shaped bracket 432 is hinged on the movable step plate 41, at this time, as the right bevel of the inverted V-shaped bracket 432 approaches the left side, the angle decreases, and vice versa.

[0044] By adjusting the size of the angle at the top of the inverted V-shaped bracket 432, while ensuring that steel bars of different diameters can be loaded smoothly, it can adapt to the limit positions of steel bars of different diameters on the steps of the movable step plate 41 during the loading process. In addition, the inverted V-shaped bracket 432 on the lowest step of the movable step plate 41 can also more easily separate a single steel bar from a whole bundle of scattered steel bars for loading during the loading process, thereby avoiding the situation where multiple steel bars are loaded at the same time and cause slipping.

[0045] like Figure 2 、 Figure 6 and Figure 7 As shown, the adjustment member 44 also includes a mounting groove 442 opened on the step of the fixed step plate 42. The interior of the mounting groove 442 is connected to an adjustment inclined plate 441 for sliding along the left and right directions through multiple connecting plates. The rear side surface of the fixed step plate 42 is threadedly connected with a limiting bolt 2 for limiting the connecting plate inside the mounting groove 442.

[0046] Specifically, when adjusting the width of the steel bar placement position on each step of the fixed step plate 42 through the adjusting piece 44, the staff first loosens the limit bolt 2 on the fixed step plate 42, cancels the limit of the adjusting inclined plate 441 inside the mounting slide groove 442, and then pushes the adjusting inclined plate 441 to move inside the mounting slide groove 442. When the adjusting inclined plate 441 moves to the left, an obstruction is formed between the adjusting inclined plate 441 itself and the horizontal surface of the steps of the fixed step plate 42, thereby changing the distance between the steel bars placed on the horizontal surface of the steps of the fixed step plate 42. When the distance of the adjusting inclined plate 441 moving to the left gradually increases, the width of the steel bar placement position on the steps of the fixed step plate 42 gradually decreases. Conversely, when the adjusting inclined plate 441 moves to the right and is completely retracted into the inside of the mounting slide groove 442, the steps of the fixed step plate 42 are at the maximum placement width.

[0047] like Figure 2 、 Figure 8 and Figure 9 As shown, the positioning member 45 also includes a guide bar 456 fixedly connected to the corresponding step position on the front side of the fixed step plate 42, and the front surface of the fixed step plate 42 is located on the right side of the guide bar 456 and is fixedly connected to the limiting sleeve 455. The limiting sleeve 455 and the guide bar 456 are jointly connected with a positioning bar 454 for sliding along the up and down directions. The bottom end of the front surface of the positioning bar 454 is fixedly connected to ear plate 1, and the bottom end of the front surface of the limiting sleeve 455 is fixedly connected to ear plate 2. The upper surface of ear plate 1 is fixedly connected to a reset rod 459, and the top end of the reset rod 459 passes through the upper surface of ear plate 2 and is elastically slidably connected to ear plate 2. A reset spring is provided on the circumferential surface of the reset rod 459 and located above ear plate 2.

[0048] like Figure 2 、 Figure 8 and Figure 9 As shown, the positioning member 45 also includes a sliding frame 453 fixedly connected to the corresponding step position on the front surface of the fixed step plate 42, the sliding frame 453 is located on the right side of its corresponding positioning bar 454, and a sliding pull plate 452 is slidably connected to the sliding frame 453 in the up and down directions, and a pull rope 458 is fixedly connected to the left side of the lower surface of the sliding pull plate 452, and the front surface of the fixed step plate 42 and located below the sliding frame 453 are fixedly connected with a phase-changing wheel group 457, and the end of the pull rope 458 away from the sliding pull plate 452 passes around the phase-changing wheel group 457 and is fixedly connected to the lower surface of the ear plate one, and a push plate 451 is fixedly connected to the position of the sliding pull plate 452 on the rear surface of the movable step plate 41, and the push plate 451 is located below the sliding pull plate 452.

[0049] Specifically in the process of loading, the linkage plate 35 drives the movable step plate 41 to move up and down to load the steel bars one by one. When the movable step plate 41 moves upward, the movable step plate 41 drives the push plate 451 to move upward synchronously. The rear end of the push plate 451 contacts the lower surface of the sliding pull plate 452, pushing the sliding pull plate 452 to move upward on the sliding frame 453. The sliding pull plate 452 bypasses the phase-changing wheel group 457 through the pull rope 458 to pull the ear plate on the positioning bar 454 to move synchronously. The positioning bar 454 moves with the ear plate in the limit sleeve 455 and the guide The guide bar 456 slides downward between the bars 456, and at the same time, the positioning bar 454 drives the reset rod 459 to slide downward on the ear plate 2 through the ear plate 1, and compresses the reset spring. The setting of the limit sleeve 455 and the guide bar 456 can ensure that the positioning bar 454 slides in the direction of the vertical surface of the step of the fixed step plate 42. At this time, when the fixed step plate 42 moves upward to push the steel bars on each level of the fixed step plate 42 upward by one level, the positioning bar 454 moves downward, so that the left side of the step on the fixed step plate 42 is in an open state, ensuring normal loading of the steel bars.

[0050] When the movable step plate 41 moves downward, the pushing plate 451 no longer generates a thrust on the sliding pull plate 452. Under the action of the elastic force of the reset spring itself, the reset rod 459 is pushed upward, and the reset rod 459 drives the positioning bar 454 to move upward through the ear plate. At this time, the top of the positioning bar 454 exceeds the horizontal plane of the step of the fixed step plate 42, and the left side of the step of the fixed step plate 42 is in a closed state, limiting the steel bars placed on each level of the fixed step plate 42 to prevent the steel bars placed on the fixed step plate 42 from slipping when the movable step plate 41 moves downward to load new steel bars.

[0051] As the movable step plate 41 moves up and down reciprocatingly, the steel bars are pushed upward step by step, and the steel bars are transported to the next production process through the top end of the fixed step plate 42.
