[0002] As a kind of grid-shaped metal component welded by bearing flat steel and twisted steel according to certain longitude-latitude spacing, steel grating is widely used in industrial platform, ditch cover plate, stair step and other fields due to its advantages of ventilation, light transmission, strong bearing capacity and anti-skid.

[0003] In actual application, steel grating needs to be cut according to on-site size, and first, it is unpacked, then it is transferred to cutting equipment by conveying device to ensure safety and cut to size.

[0004] However, in the conveying process, due to the inherent grid-shaped structure of steel grating, its contact with conveying device (especially roller or belt conveyor) is discontinuous line contact or point contact, which leads to uneven friction and poor positioning. When accelerating, decelerating or starting and stopping, steel grating is prone to slip, shift or deflect on the conveying surface, thereby deviating from the predetermined conveying track and the final cutting positioning point, which requires manual secondary correction and positioning of steel grating by operators, increases labor intensity and reduces work efficiency.

A circular hole 8 is formed in the end face of the cavity 6. A plurality of first sliding grooves 9 are uniformly formed in the side wall of the circular hole 8, and the extension lines of the plurality of first sliding grooves 9 intersect at the center of the circular hole 8. Each first sliding groove 9 is slidably installed with an installation rod 10, and a plurality of rolling balls 11 are movably embedded on the side of each installation rod 10 close to the through hole 7, the rolling balls 11 correspond to the through holes 7 one by one, and the cavity 6 is provided with a driving mechanism for driving the installation rod 10 to move along the first sliding groove 9.

[0025] As shown in Figure 2 , a strip-shaped second sliding groove 12 is formed in the side wall of the installation groove, the second sliding groove 12 penetrates the side wall of the frame 1, a sliding block 13 is slidably installed in the second sliding groove 12, and the telescopic rod 4 is horizontally fixedly installed on the side wall of the sliding block 13. A first magnet 14 is embedded on the side wall of the sliding block 13, a second magnet 15 is fixedly installed on the side wall of the second sliding groove 12, the first magnet 14 and the second magnet 15 repel each other, and the second magnet 15 is located at one end of the second sliding groove 12 close to the cutting station.

[0026] As shown in Figure 5 , the driving mechanism comprises a sliding plate 16 slidably installed in the cavity 6, and a first elastic member 17 is jointly installed between the sliding plate 16 and the end of the cavity 6 away from the circular hole 8. A push block 18 with a tapered end is fixedly installed on the side wall of the sliding plate 16 close to the installation rod 10, and the tip of the push block 18 points to the circular hole 8.

[0027] As shown in Figure 4 , Figure 5 , the sliding plate 16 is made of magnetic material, and a coil 19 connected in series with the motor 3 is fixedly installed on the frame 1, when the motor 3 is powered on, a magnetic field is generated around the coil 19, and the adjacent ends of the coil 19 and the sliding plate 16 have different magnetic poles, so that the sliding plate 16 is attracted when the motor 3 is powered on. An elastic rope 20 is jointly installed between the installation rod 10 and the end of the first sliding groove 9 close to the circular hole 8, and the elastic coefficient of the first elastic member 17 is greater than that of the elastic rope 20.

[0028] When the motor 3 is not powered on, the first elastic member 17 does not deform, at this time, under the action of the first elastic member 17, the push block 18 is inserted between the plurality of installation rods 10, the side wall of the installation rod 10 is attached to the side wall of the cavity 6, the elastic rope 20 is in a stretched state, and the rolling balls 11 extend out of the through holes 7.

[0029] When the motor 3 is powered on, a magnetic field is generated around the coil 19 which attracts the slide plate 16, under the action of the attraction, the slide plate 16 drives the push block 18 to pull out from between the plurality of mounting rods 10, the first elastic member 17 is pressed, at the same time, the elastic rope 20 pulls the mounting rod 10 close to the circular hole 8, until the ball 11 is retracted into the cavity 6.

[0030] As shown in Figure 7 The side wall of the clamping plate 5 is provided with a third sliding groove 21, and the output end of the telescopic rod 4 is slidingly inserted in the third sliding groove 21, and the second elastic member 22 is installed between the output end of the telescopic rod 4 and the top wall of the third sliding groove 21.

[0031] In the process of the clamping plate 5 being adjusted and clamping the steel grating, the steel grating is in contact with the ball 11, and the second elastic member 22 is in a relaxed state.

[0032] When the motor 3 is started and the ball 11 is retracted into the cavity 6, under the action of the gravity of the steel grating, the steel grating falls onto the surface of the rotating roller 2, and the clamping plate 5 moves downward together with the steel grating, and the second elastic member 22 is in a stretched state, which ensures that the clamped steel grating can be in contact with the rotating roller 2.

[0033] In the initial state, the telescopic rod 4 is in a contracted state, and the clamping plate 5 is located in the second sliding groove 12, at this time, under the action of the repulsion between the first magnet 14 and the second magnet 15, the clamping plate 5 is located at the end of the second sliding groove 12 away from the cutting station.

[0034] For the steel grating with a surface hole smaller than the diameter of the ball 11: when the steel grating needs to be conveyed, first, the motor 3 is in a powered-off state, at this time, the ball 11 is in a state of extending out of the through hole 7.

[0035] Then place the steel grating that has been disassembled on the surface of the rotating roller 2, and then control the telescopic rod 4 to extend, thereby driving the two clamping plates 5 to move close to each other, and clamp the steel grating through the two clamping plates 5, and through the clamping plate 5, the steel grating can be directly contacted with the ball 11 during the adjustment and clamping of the steel grating, thereby reducing the friction force on the steel grating during the adjustment process, and preventing the surface of the steel grating from being worn.

[0036] Then start the motor 3, retract the ball 11 into the cavity 6, and the steel grating is in contact with the rotating roller 2.

[0037] When the rotating roller 2 moves the steel grating through friction, the clamping plate 5 moves together with the steel grating.

[0038] When the rotating roller 2 drives the steel grating to move to the designated position, the telescopic rod 4 is controlled to retract, at this time, the clamping plate 5 drives the first magnet 14 to gradually approach the second magnet 15, and when the clamping plate 5 retracts into the second sliding groove 12, under the action of the repulsion between the first magnet 14 and the second magnet 15, the first magnet 14 drives the clamping plate 5 and the sliding block 13 to move to the end of the second sliding groove 12 away from the cutting station, in preparation for the next work.

[0039] Therefore, during the rotation of the rotating roller 2 and the movement of the steel grating, the steel grating can be clamped by the clamping plate 5 to prevent the steel grating from shaking on the surface of the rotating roller 2, ensuring that the steel grating can be transferred to the designated position without the need for secondary alignment, thereby improving work efficiency.

[0040] As shown in Figure 5 The push block 18 includes a round rod 1802 and a tapered block 1801, and the two ends of the round rod 1802 are fixedly connected with the tapered block 1801 and the sliding plate 16 respectively, so that when the push block 18 moves towards the circular hole 8, the tapered block 1801 is first inserted between the plurality of mounting plates, and then the round rod 1802 is inserted between the plurality of mounting rods 10, thereby providing support force to the mounting plates through the round rod 1802, and when the steel grating is placed on the surface of the ball 11, the round rod 1802 prevents the ball 11 from retracting into the cavity 6.

[0041] As shown in Figure 6 The side wall of the mounting rod 10 is provided with a clamping hole 23, and the ball 11 is movably embedded in the clamping hole 23; The side wall of the clamping hole 23 is provided with a pressure relief hole 24 communicating with the outside; The side wall of each clamping hole 23 is provided with an air hole 25 communicating with a flow guide groove 27; the rotating roller 2 is provided with an annular cavity 26, and the side wall of the annular cavity 26 is uniformly provided with the flow guide groove 27; The rotating roller 2 is provided with a gas supply mechanism for supplying gas to the annular cavity 26.

[0042] The first elastic member 17 is made of an elastic material; The gas supply mechanism includes a pressurized cavity 28 provided on the first elastic member 17, and the side wall of the pressurized cavity 28 is respectively embedded with an air inlet valve 29 and an air outlet valve 30; The input end of the air inlet valve 29 penetrates through the side wall of the rotating roller 2 and communicates with the outside; The output end of the air outlet valve 30 penetrates through the sliding plate 16 and the push block 18 and extends into the annular cavity 26.

[0043] When the motor 3 is powered off, the first elastic member 17 is squeezed, at this time, the gas in the pressurized cavity 28 is discharged into the annular cavity 26 through the air outlet valve 30, then discharged into the clamping hole 23 through the flow guide groove 27 and the air hole 25, and finally discharged through the gap between the side wall of the clamping hole 23 and the ball 11 and the pressure relief hole 24.

[0044] Since dust is generated when the steel grating is cut, the gas discharged from the pressurized cavity 28 is discharged to the outside through the pressure relief hole 24 in the side wall of the clamping hole 23 located in the bottom wall of the rotating roller 2.

[0045] During the gas discharge process of the pressure relief hole 24, the dust in the clamping hole 23 is discharged to the outside along with the gas flow, thereby reducing the resistance received by the ball 11 when it rotates, and further ensuring that the steel grating can rotate smoothly when the clamping plate 5 is used to align the steel grating, thereby ensuring that the steel grating can be aligned.

[0046] As shown in Figure 5 The side wall of the push block 18 is a mirror surface, and the push block 18 is made of stainless steel material. By setting the side wall of the push block 18 as a mirror surface, the friction between the push block 18 and the mounting rod 10 can be reduced, thereby ensuring that the mounting rod 10 can move smoothly when the push block 18 pushes the mounting rod 10 to move along the first sliding groove 9.

[0047] As shown in Figure 7 The top wall and the bottom wall of the sliding block 13 are both provided with a strip-shaped groove 31, which is parallel to the first sliding groove 9, thereby reducing the friction between the sliding block 13 and the first sliding groove 9, and ensuring that the sliding block 13 can be reset under the repulsive force between the first magnet 14 and the second magnet 15.

[0048] Method for use: when the steel grating needs to be conveyed, first, the motor 3 is in a power-off state, at which time the ball 11 is in a state of extending through the through hole 7.

[0049] Then place the steel grating that has been disassembled on the surface of the rotating roller 2, and then control the extension of the telescopic rod 4, thereby driving the two clamping plates 5 to move close to each other, and clamping the steel grating through the two clamping plates 5. When the clamping plates 5 are used to align and clamp the steel grating, the steel grating can be in direct contact with the ball 11, thereby reducing the friction received by the steel grating during the alignment process, and preventing the surface of the steel grating from being worn. When the output ends of the two telescopic rods 4 are extended by a specified length, the steel grating can be aligned.

[0050] Then start the motor 3, and the ball 11 is retracted into the cavity 6, and the steel grating is in contact with the rotating roller 2.

[0051] When the rotating roller 2 moves the steel grating through friction, the clamping plate 5 moves with the steel grating.

[0052] When the rotating roller 2 drives the steel grating to move to the designated position, the telescopic rod 4 is controlled to retract, at this time, the first magnet 14 is gradually close to the second magnet 15 by the clamp plate 5, when the clamp plate 5 retracts into the second sliding groove 12, under the repulsion between the first magnet 14 and the second magnet 15, the first magnet 14 drives the clamp plate 5 and the sliding block 13 to move to the end of the second sliding groove 12 away from the cutting station, in order to prepare for the next work.

[0053] Therefore, during the rotating roller 2 rotates and drives the steel grating to move, the steel grating can be clamped by the clamp plate 5, the steel grating is prevented from shaking on the surface of the rotating roller 2, the steel grating can be transferred to the designated position, the steel grating does not need to be placed again, and the working efficiency is improved.

[0054] The above merely describes the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical scheme of the present application and the improved concept thereof within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
