[0024] A piston 9 is fixedly connected to the end of the slide rod 8 away from the drive link 6, and the piston 9 is slidingly connected inside the damping tank 7, two symmetrical through holes 10 are arranged on the piston 9, the two pistons 9 divide the inside of the damping tank 7 into three independent chambers, each chamber is communicated with each other through the through hole 10, and the inside of the damping tank 7 is filled with an oily substance.

[0025] A support 11 is fixedly connected to the middle of both sides of the first support frame 3, and the damping tank 7 is fixedly connected to the top of the support 11, a rotating disc 12 is rotatably connected inside the support 11, and two symmetrical eccentric shafts are arranged at the inner edge of the rotating disc 12.

[0026] The rotating disc 12 is rotatably connected with a synchronous link 13 inside through the eccentric shaft, the end of the synchronous link 13 away from the rotating disc 12 is rotatably connected to the bottom of the end of the slide rod 8 away from the piston 9, and the synchronous link 13 and the rotating disc 12 constitute a synchronous assembly for synchronous movement of the two slide rods 8.

[0027] The rotating disc 12 is provided with two symmetrical distribution on the top of the first support frame 3, and the two rotating discs 12 are connected by a link to realize synchronous movement, the link and the boiler body 1 do not interfere with each other, and a rotating speed monitoring module is arranged outside the support 11, and the rotating speed monitoring module is connected with the rotating shaft of the rotating disc 12.

[0028] When the boiler body 1 is subjected to vertical vibration, the support ear 2 will move up and down, the bottom of the support ear 2 is connected with the top of the support rod 4 through the spring, and the spring is compressed or stretched when the support ear 2 moves, thereby absorbing part of the vibration energy, at the same time, the drive link 6 hingedly connected with the support ear 2 will rotate around the hinge point, push or pull the slide rod 8, the slide rod 8 is fixedly connected with the piston 9 inside the damping tank 7, and the piston 9 slides inside the damping tank 7.

[0029] The damping tank 7 is filled with an oily substance, the through hole 10 on the piston 9 allows the oily substance to flow between the three independent chambers, generating viscous damping force to consume vibration energy, and the synchronous assembly ensures symmetrical movement: the movement of the slide bar 8 is transmitted to the rotating disc 12 through the synchronous connecting rod 13, one end of the synchronous connecting rod 13 is rotatably connected with the bottom of the slide bar 8, and the other end drives the rotating disc 12 to rotate through the eccentric shaft inside the rotating disc 12, the two rotating discs 12 are connected through connecting rods to realize synchronous rotation, thereby ensuring consistent movement of the slide bars 8 on both sides.

[0030] The rotating speed monitoring module arranged outside the support 11 is connected with the rotating shaft of the rotating disc 12, and can monitor the rotating speed of the rotating disc 12 in real time; when the vertical vibration of the boiler body 1 is large, the sliding speed of the slide bar 8 increases, and the rotating speed of the rotating disc 12 increases, and the rotating speed monitoring module can feed back the abnormal vibration condition through local audible and light alarms or remote alarm sending when the rotating speed is too high.

[0031] Embodiment two: on the basis of embodiment one, please refer to Figure 7 and Figure 8 The following structure is also disclosed: The transverse vibration reduction structure comprises a second support frame 14 mounted at the bottom of the first support frame 3, the first support frame 3 is slidably connected inside the second support frame 14, the second support frame 14 is provided with first guide grooves 15 at both ends of the inner side, the first support frame 3 is rotatably connected with first pulleys 16 at the four corners of the bottom, and the first pulleys 16 are matched with the first guide grooves 15.

[0032] The first support frame 3 is fixedly connected with two symmetrically distributed first spring dampers 17 on both sides, and the first spring dampers 17 are located between the outer side of the first support frame 3 and the inner side of the second support frame 14, the second support frame 14 is slidably connected with first reset sliding blocks 18 at both ends of the inner side, and the first reset sliding blocks 18 are provided with springs at the bottom, the first support frame 3 is provided with first reset grooves 19 matched with the first reset sliding blocks 18 at both ends of the middle, the first reset sliding blocks 18 are clamped and connected inside the first reset grooves 19, and the contact surfaces of the first reset sliding blocks 18 and the first reset grooves 19 are arc surfaces.

[0033] When the boiler body 1 is subjected to transverse vibration, the first support frame 3 slides in the second support frame 14, the first pulleys 16 at the bottom of the first support frame 3 roll along the first guide grooves 15 on the inner side of the second support frame 14 to reduce friction and guide movement; the first spring dampers 17 are located between the outer side of the first support frame 3 and the inner side of the second support frame 14, and are compressed or stretched when the first support frame 3 slides, thereby providing transverse vibration reduction effect.

[0034] The bottom of the first reset sliding block 18 inside the second support frame 14 is provided with a spring, which always applies an upward force to the first reset sliding block 18, so that the first reset sliding block 18 remains in the state of being clamped and connected with the first reset slot 19 arranged in the middle of the two ends of the first support frame 3. Since the contact surfaces of the first reset sliding block 18 and the first reset slot 19 are both arc surfaces, when the first support frame 3 slides due to transverse vibration, the arc surface of the first reset slot 19 will generate a downward pressure on the first reset sliding block 18, forcing the first reset sliding block 18 to slide downward against the action of the bottom spring, so that the first reset sliding block 18 smoothly disengages from the first reset slot 19, without affecting the damping movement of the first support frame 3. When the transverse vibration weakens or stops, the sliding speed of the first support frame 3 slows down, the spring at the bottom of the first reset sliding block 18 recovers the deformation and pushes the first reset sliding block 18 to slide upward to reset. At this time, the first support frame 3 moves to the initial position under the resetting force of the first spring damper 17, and when the first reset slot 19 is aligned with the first reset sliding block 18 again, the first reset sliding block 18 is clamped into the first reset slot 19, assisting the first support frame 3 to accurately return to the initial position, realizing transverse self-resetting.

[0035] Example three: on the basis of example one and example two, please refer to Figures 7 to 10 The following structure is also disclosed: The longitudinal damping structure includes a third support frame 20 mounted at the bottom of the second support frame 14, the second support frame 14 is slidably connected inside the third support frame 20, and the sliding direction of the second support frame 14 is perpendicular to the sliding direction of the first support frame 3. The third support frame 20 is provided with symmetrically distributed second guide slots 21 on both sides, and the second support frame 14 is rotatably connected with second pulleys 22 at the four corners of the bottom, and the second pulleys 22 are matched with the second guide slots 21.

[0036] The second support frame 14 is fixedly connected with symmetrically distributed second spring dampers 23 on both sides, and the second spring dampers 23 are located outside the second support frame 14 and inside the third support frame 20. The second guide slots 21 are provided with guide rails 24 on both sides, and the second support frame 14 is provided with sliding grooves 25 matched with the guide rails 24 on both sides.

[0037] The guide rail 24 is fixedly connected with a mounting box 26 in the middle, the second reset sliding block 27 is slidably connected inside the mounting box 26, the bottom of the second reset sliding block 27 is fixedly connected with a spring, and the upper end of the second reset sliding block 27 extends to the top of the mounting box 26. The second support frame 14 is provided with a second reset slot 28 matched with the second reset sliding block 27 in the middle on both sides, and the contact surfaces of the second reset sliding block 27 and the second reset slot 28 are both arc surfaces.

[0038] When the boiler body 1 is subjected to longitudinal vibration, the second supporting frame 14 slides in the longitudinal direction inside the third supporting frame 20, the sliding direction being perpendicular to the transverse sliding of the first supporting frame 3, the second pulley 22 at the bottom of the second supporting frame 14 rolls along the second guide groove 21 on both sides of the third supporting frame 20, ensuring smooth movement.

[0039] The second spring damper 23 is located outside the second supporting frame 14 and inside the third supporting frame 20, providing damping force when sliding, the guide rail 24 is fixed on both sides of the second guide groove 21, and the sliding groove 25 of the second supporting frame 14 matches the guide rail 24, limiting the movement trajectory.

[0040] The mounting box 26 fixedly connected in the middle of the guide rail 24 is slidably connected with the second reset slider 27 inside, the spring fixedly connected at the bottom of the second reset slider 27 always applies an upward force to it, so that the upper end of the second reset slider 27 extends to the top of the mounting box 26 and is clamped and connected with the second reset groove 28 arranged in the middle of both sides of the second supporting frame 14, since the contact surfaces of the second reset slider 27 and the second reset groove 28 are both arc surfaces, when the second supporting frame 14 slides due to longitudinal vibration, the arc surface of the second reset groove 28 will generate a downward pressure on the second reset slider 27, forcing the second reset slider 27 to slide downward against the action of the bottom spring, smoothly disengaging from the second reset groove 28 and not hindering the damping movement; when the longitudinal vibration weakens or stops, the second supporting frame 14 moves to the initial position under the resetting force of the second spring damper 23, the bottom spring of the second reset slider 27 restores the deformation and pushes it to reset upward, when the second reset groove 28 is aligned with the second reset slider 27, the second reset slider 27 is clamped into the second reset groove 28, assisting the second supporting frame 14 to accurately return to the initial position, realizing longitudinal self-resetting, through the synergistic effect of the three-way damping structure, the device can effectively dampen any direction vibration of the boiler body 1, and through the self-resetting structure in each direction, the device can ensure that it returns to the initial working state after the vibration stops.
