When the flue gas when the inside burning of radiant tube, the temperature of radiant tube is higher, the temperature in the telescopic link 13 rose equally under the effect of heat conduction stick 14 this moment, consequently memory alloy silk 15 extends and drives telescopic link 13 and extends, thereby can violently manage 3 with the first, the second violently manages 4, the third violently manages 7, the fourth violently manages 8 and fixes in corresponding second draw-in groove 12, cardboard 10 is tightly fixed at first violently pipe 3 this moment, the second violently manages 4, the third violently manages 7, the fourth violently manages 8 on, thereby when violently managing 4 and the shake of third violently pipe 7 in the second, can receive first violently pipe 3 pulling force that makes progress under the effect of cardboard 10, receive the second and violently manage 4 ascending holding power of 4 simultaneously, played and prevented that the second violently manages 4 and the flagging effect of 7 with the third.
When long-time use leads to cardboard 10 impaired fracture, stop letting in the gas in to the radiant tube, wait to the radiant tube cooling back that gets off, memory alloy silk 15 shrink, cardboard 10 can rotate around first violently pipe 3 this moment to can take out cardboard 10 through rotatory cardboard 10, consequently played quick replacement's effect.
When the flue gas is burnt in the radiant tube, the temperature around the radiant tube is higher, the temperature in the first cavity 17 rises under the effect of heat exchange this moment, therefore the ammonia is heated and expanded, the expanded ammonia pushes the anti-skid pad 16 to expand, thereby can be with first violently pipe 3 and first draw-in groove 11, the second violently pipe 4, the third violently pipe 7, the gap between the fourth violently pipe 8 and the corresponding second draw-in groove 12 is filled up, the impact force that cardboard 10 received has been reduced in the radiant tube vibrations process, the effect of reducing cardboard 10 damage probability has been played, and after the gap is filled up, the home range of cardboard 10 reduces, thereby the effect of reducing cardboard 10 aversion probability has been played, radiant tube striking recess 18 in the course of the work, the gas in recess 18 was discharged this moment, consequently radiant tube and anti-skid pad 16 are adsorbed together under the effect of external atmospheric pressure, will be pulled anti-skid pad 16 when the radiant tube takes place to shake, anti-skid pad 16 has the reaction force to the radiant tube this moment, consequently, the effect that has reduced radiant tube shake degree has been played.
When the length of the first transverse pipe 3, the second transverse pipe 4, the third transverse pipe 7 and the fourth transverse pipe 8 is long, a plurality of clamping plates 10 are arranged to apply upward force to the third transverse pipe 7 and the fourth transverse pipe 8, at the moment, two adjacent clamping plates 10 are connected together through the first screw hole 19, the second screw hole 20 and the connecting rod 21, two clamping plates 10 are attached together in a shaking prevention process, the effect of ensuring the uniform stress of the third transverse pipe 7 and the fourth transverse pipe 8 is achieved, when the bidirectional threaded rod 2101 is rotated, the distance between the two supporting rods 2102 is changed, the distance between the two clamping plates 10 can be adjusted at will, when the plurality of clamping plates 10 are required to be used, the effect of ensuring that each clamping plate 10 can be in the best position is achieved, the effect of ensuring that the clamping plates 10 can be rotated along with the bidirectional threaded rod 2101 under the effect of the rotation prevention mechanism when the connecting rod 21 shakes together with the clamping plates 10 is achieved, and the effect of ensuring that the clamping plates 10 can stay in the best position is achieved; when the distance between the two clamping plates 10 is adjusted, the polygonal clamping block 23 retracts into the through hole 22 under the action of the driving mechanism, at the moment, the bidirectional threaded rod 2101 can normally rotate, after the clamping block 23 moves to a specified position, the clamping block 23 extends out of the through hole 22 under the action of the driving mechanism and always has a tendency of entering the third clamping groove 24, so that when the clamping plate 10 drives the linkage rod to shake to cause the bidirectional threaded rod 2101 to rotate, the bidirectional threaded rod 2101 only needs to slightly rotate, the clamping block 23 with the extending tendency can enter the third clamping groove 24, and at the moment, the effect of preventing the bidirectional threaded rod 2101 from greatly rotating is achieved under the combined action of the third clamping groove 24 and the clamping block 23; when the bidirectional threaded rod 2101 is rotated, an operator holds the bidirectional threaded rod 2101, the palm pushes the push rod 25, the push rod 25 retracts into the through hole 22, the push rod 25 pushes the connecting rope 26 in the process, the connecting rope 26 pulls the clamping block 23, the clamping block 23 retracts into the through hole 22, after the bidirectional threaded rod 2101 rotates to a specified position, the operator releases his hand, the spring 34 pushes the clamping block 23 to extend out of the through hole 22, and therefore the clamping block 23 is driven to move in the whole process.
The clamping plate 10 slightly shakes in the working process, because the gas with higher temperature is positioned in the upper space, and in the shaking process, the elastic sheet 27 deforms, so that the second cavity 28 and the third cavity 29 absorb the gas with lower temperature from the lower part of the second transverse pipe 4 at any time under the action of the first guide pipe 30 and the second guide pipe 31, the clamping plate 10 can be cooled, the hot gas in the second cavity 28 and the third cavity 29 can be exhausted through the first guide pipe 30 and the second guide pipe 31, the exhausted hot gas flows upwards rapidly, the time of the clamping plate 10 in a high-temperature state is shortened, under long-term high-temperature vibration, the effect of reducing the probability of fatigue fracture of the clamping plate 10 is achieved, the mounting rod 32 and the spoiler 33 are driven to move up and down in the process of the elastic sheet 27, and therefore the gas sucked into the second cavity 28 and the third cavity 29 can be uniformly dispersed in the second cavity 28 and the third cavity 29 in time, and therefore a certain part of the clamping plate 10 is prevented from being overheated, the fatigue fracture of the part is prevented, and the effect of reducing the probability of the clamping plate 10 is achieved.
