Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figs. 1-3 , the utility model provides a kind of technical solutions: a furnace mouth plug clamp of carbon block roaster, including recessed frame 1 and two clamping plates 2, two clamping plates 2 are distributed evenly in recessed frame 1 lower end left and right, recessed frame 1 is rotatably connected with bidirectional screw rod 4, the left and right ends of the periphery of bidirectional screw rod 4 are all screw threadedly sleeved with guide block 5, the outside of guide block 5 is all fixed with recessed push rod 9, recessed push rod 9 is all slidably penetrated out of recessed frame 1, and the end of recessed push rod 9 is all fixed with push plate 10, push plate 10 is all connected with adjacent clamping plate 2 between pressure sensing switch 13 and elastic switch 25, recessed frame 1 upper side is equipped with pressure alarm 26, bidirectional screw rod 4 is equipped with clamping drive assembly outside, clamping drive assembly includes positive and negative motor 6, main gear 7 and auxiliary gear 8, positive and negative motor 6 is fixed on recessed frame 1 upper end right side, main gear 7 is connected with the power end of positive and negative motor 6, auxiliary gear 8 is fixedly sleeved on the periphery of bidirectional screw rod 4, and auxiliary gear 8 is engaged with main gear 7, recessed frame 1 upper end middle part is fixed with hoisting frame 3, bidirectional screw rod 4 is rotatably penetrated through hoisting frame 3, pressure alarm 26 is connected with the side of hoisting frame 3.

[0022] When the carbon block is clamped by the clamp, the carbon block is located between the two clamping plates 2, the main gear 7, the secondary gear 8 and the bidirectional screw rod 4 are driven to rotate by the forward and reverse motor 6, the bidirectional screw rod 4 drives the two guide blocks 5 to approach each other, so the guide blocks 5 drive the concave push rod 9, the push plate 10, the pressure sensitive switch 13, the elastic switch 25 and the clamping plate 2 to approach the carbon block, until the clamping plate 2 clamps the carbon block, because the clamping plate 2 exerts pressure on the pressure sensitive switch 13, the pressure sensitive switch 13 is started after being subjected to the pressure, under the premise that the pressure sensitive switch 13 is connected in series with the pressure alarm 26, the pressure sensitive switch 13 controls the pressure alarm 26 to emit an alarm sound, at this time, it represents that the clamping plate 2 clamps and fixes the carbon block, so it is beneficial to accurately judge that the carbon block is clamped and fixed, and to avoid that the clamping plate 2 continues to exert pressure on the carbon block to prevent the carbon block from being damaged due to excessive clamping force.

[0023] In the embodiment, the inner side of the clamping plate 2 is connected with a plurality of anti-skid protrusions 12.

[0024] By arranging a plurality of anti-skid protrusions 12 on the inner side of the clamping plate 2, when the clamping plate 2 clamps the carbon block, the anti-skid protrusions 12 are beneficial to improve the friction when contacting the carbon block, thereby being beneficial to better prevent the carbon block from slipping.

[0025] In the embodiment, the lower end of the push plate 10 is provided with a lifting plate 11, the inner side of the lifting plate 11 is provided with a receiving groove 18, the receiving groove 18 is fixed with a guide rod 19, the guide rod 19 is sleeved with a reset spring 20, and the guide rod 19 is sleeved with a magnetic block 22, the reset spring 20 is connected between the inner side of the magnetic block 22 and the inner wall of the receiving groove 18, the inner side of the magnetic block 22 is fixed with a limiting plate 17 extending out of the receiving groove 18, the inner wall of the receiving groove 18 is fixed with an electromagnet 21, the electromagnet 21 is attracted to the adjacent magnetic block 22 by magnetic force, the lower end of the push plate 10 is provided with a contraction groove 15, the top of the contraction groove 15 is connected with a return spring 16, the lower end of the return spring 16 is connected with a lifting rod 23 slidingly connected in the contraction groove 15, and the lifting rod 23 extends downward out of the contraction groove 15, the push plate 10 is fixed to the lower end of the adjacent lifting rod 23, and the inner side of the limiting plate 17 is rotatably connected with a roller 24.

[0026] When the clamping plate 2 clamps the carbon block, and before the elastic switch 25 is pressed, the electromagnet 21 is set to be powered on, so at this time the electromagnet 21 is attracted to the magnetic block 22 by magnetic force, and the magnetic block 22 is stretched by the reset spring 20. When the elastic switch 25 is pressed, the elastic switch 25 is set to be in series with the electromagnet 21, and the elastic switch 25 is pressed off. At this time, the electromagnet 21 is powered off, so the electromagnet 21 no longer attracts the magnetic block 22 by magnetic force. Then the elastic force of the reset spring 20 drives the magnetic block 22 and the limiting plate 17 to move out of the storage slot 18 until the limiting plate 17 is located at the lower end of the carbon block. Then the limiting plate 17 pre-supports and limits the carbon block. Even if the clamping force of the clamping plate 2 is insufficient due to mechanical failure, the limiting plate 17 can prevent the carbon block from falling and supporting the carbon block below, avoiding the situation that the carbon block slips and falls during the transfer process. This reduces the safety hazards during the transfer process of the carbon block.

[0027] In this embodiment, the push plate 10 is connected to the adjacent clamping plate 2 by at least two spring return rods 14.

[0028] When the clamping plate 2 clamps the carbon block, the spring return rod 14 will be compressed at the same time. Therefore, when the clamping plate 2 releases the carbon block, the spring return rod 14 will reset the clamping plate 2 by the elastic force, so the clamping plate 2 will not press the pressure-sensitive switch 13 and the elastic switch 25. This is beneficial for clamping the subsequent carbon block by the clamping plate 2.

[0029] Working principle

[0030] When the clamping plate 2 clamps the carbon block, first, the lifting plate 11 is in contact with the supporting surface of the carbon block, and when the clamp continues to move downward, the lifting plate 11 pushes the lifting rod 23 into the contraction groove 15, and the lifting rod 23 compresses the return spring 16, until the lower end surface of the clamping plate 2 is in contact with the supporting surface of the carbon block, at this time, the lower end surface of the lifting plate 11 is flush with the lower end surface of the clamping plate 2, when the carbon block is clamped by the clamp, under the premise that the carbon block is located between the two clamping plates 2, the main gear 7, the secondary gear 8 and the bidirectional screw rod 4 are driven to rotate by the working of the forward and reverse motor 6, the bidirectional screw rod 4 drives the two guide blocks 5 to move close to each other, so that the guide block 5 drives the concave push rod 9, the push plate 10, the pressure sensitive switch 13, the elastic switch 25 and the clamping plate 2 to move close to the carbon block, until the clamping plate 2 clamps the carbon block, the pressure sensitive switch 13 controls the pressure alarm 26 to emit an alarm sound, at this time, it represents that the clamping plate 2 clamps and fixes the carbon block, once the clamping plate 2 clamps the carbon block, since the elastic switch 13 is pressed off by the clamping plate 2, at this time, the electromagnet 21 is powered off, so that the electromagnet 21 no longer attracts the magnetic block 22 by magnetic force, then the rebounding force of the return spring 20 drives the magnetic block 22 and the limiting support plate 17 to move out of the storage groove 18, when the limiting support plate 17 moves out, the roller 24 is in contact with the side surface of the clamping plate 2, when the hoisting equipment drives the clamp to move upward and drives the carbon block to move upward, since the supporting surface of the carbon block no longer supports the lifting plate 11, the rebounding force of the return spring 16 drives the lifting rod 23 and the lifting plate 11 to move downward and reset, in this process, the roller 24 rotates along the side surface of the clamping plate 2, which is beneficial to ensure the smoothness of the downward movement of the lifting plate 11, until the lifting plate 11 is reset, since the clamping plate 2 no longer abuts against the roller 24, the rebounding force of the return spring 20 continues to drive the magnetic block 22 and the limiting support plate 17 to move out of the storage groove 18, until the limiting support plate 17 is located at the lower end of the carbon block, then the limiting support plate 17 pre-supports and limits the carbon block.
