Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to a boiler drum support. Background Technology

[0002] The boiler drum is a cylindrical pressure vessel in a boiler used to contain water and steam. It is usually installed at the top of the boiler and is the core component of the boiler water circulation system. The boiler drum support is a device used to support the drum and ensure that it can expand and contract freely during operation.

[0003] A search revealed, for example, a boiler drum support disclosed in Chinese Utility Model Publication No. CN217423211U. This device features a smooth pad between the saddle and the base, allowing free relative movement between them. Simultaneously, the saddle's movement is guided by positioning studs. When the boiler drum expands due to heat, the saddle moves relative to the base towards both ends of the drum along the long axis of the elongated hole, preventing the generation of internal stress. However, this device lacks a shock-absorbing component, potentially leading to the boiler drum support failing to effectively absorb vibrations during boiler operation, thus affecting the boiler's stability and service life. While some existing technologies incorporate shock-absorbing components in their supports, their adjustability is relatively limited, making it difficult to flexibly adjust according to specific working environments and requirements, and unable to adapt to the shock absorption needs of different specifications of equipment. Therefore, this paper proposes a boiler drum support to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a boiler drum support, which not only has a good shock absorption effect but also has an adjustable degree of compression of the shock absorption spring, thereby allowing for flexible adjustment of the buffering degree.

[0005] The present invention adopts the following technical solution:

[0006] A boiler drum support includes a base, a bearing plate, and a placement plate. The placement plate is fixedly installed on the top of the bearing plate, and the top of the placement plate is used to fix the boiler drum body. The top of the base is provided with a number of first shock-absorbing components, and the top of the number of first shock-absorbing components is provided with the bearing plate.

[0007] The first damping component includes a damping adjustment cylinder, which is fixedly installed on the top surface of the base. A moving plate is slidably installed inside the damping adjustment cylinder, and the moving plate slides up and down along the inside of the damping adjustment cylinder. A hinge support is fixedly installed on the top of the moving plate, and two damping rods are fixedly installed on the bottom of the moving plate. The bottom of the two damping rods is fixedly connected to the inner bottom wall of the damping adjustment cylinder. Two inner shafts are rotatably installed inside the damping adjustment cylinder, and worm gears are fixedly installed at the rear ends of the two inner shafts. Worm gears are meshed on the side of the two worm gears away from the inner wall of the damping adjustment cylinder. A rotating shaft is fixedly installed at the center of each of the two worm gears, and a threaded rod is fixedly installed on the top of each of the two rotating shafts. Adjusting screws are threaded onto the surface of each of the two threaded rods, and adjusting plates are fixedly installed on the top of each of the two adjusting screws. The two adjusting plates move up and down along the surface of the two damping rods. A damping spring is sleeved above the adjusting plate outside the two damping rods, and the upper and lower ends of the damping springs press against the moving plate and the adjusting plate, respectively.

[0008] Preferably, functional plates are fixedly installed on both sides of the top of the base, and several sets of second shock-absorbing components are provided inside the two functional plates. The second shock-absorbing components are used to shock absorb and support the base and the bearing plate.

[0009] Preferably, the second damping component includes a movable plate, a support rod, a hinge rod, a fixed seat, and a spring damper. The movable plate is slidably installed inside the functional plate and slides up and down along the interior of the functional plate. The upper part of the movable plate is fixedly connected to the support rod, and the upper part of the support rod is used to support the load-bearing plate. The bottom two ends of the movable plate are respectively hinged to hinge rods, and the ends of the hinge rods are respectively hinged to sliders. The sliders are slidably installed inside the functional plate and slide horizontally along the interior of the functional plate. Spring dampers are respectively installed between the two sliders and the fixed seat. The fixed seat is fixedly installed on the inner bottom surface of the functional plate.

[0010] Preferably, an L-shaped plate is fixedly connected to the top of the support rod, and the L-shaped plate is fixedly connected to the bearing plate.

[0011] Preferably, the shock-absorbing adjusting cylinder is provided with guide rails on both sides, and the moving plate is provided with corresponding sliding grooves on both sides, with the sliding grooves cooperating with the guide rails.

[0012] Preferably, each of the two functional panels is equipped with two sets of second shock-absorbing components.

[0013] Preferably, the front end of the inner shaft extends outside the shock-absorbing adjustment cylinder.

[0014] The beneficial effects of this utility model are: (1) The boiler drum support, by setting the first damping component, can adjust the compression degree of the damping spring by rotating the inner shaft when it is necessary to adjust the compression degree of the damping spring. The rotation of the inner shaft will drive the worm to rotate, and the worm and the worm wheel will mesh with each other, thereby causing the threaded rod to rotate. The rotation of the threaded rod causes the adjusting inner cylinder to move in the vertical direction, thereby driving the adjusting plate to slide along the surface of the damping rod, thereby squeezing or releasing the damping spring. This design can flexibly adjust the compression degree of the damping spring according to the damping requirements of different specifications of boiler drums, and has strong practicality; (2) The setting of the second damping component, through the buffer damping effect of the spring damper, allows it to cooperate with the first damping component to play a damping role, thereby significantly improving the overall damping effect.

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0022] Example: Figures 1-5As shown, a boiler drum support includes a base 1, a number of first shock-absorbing components 2 are provided on the top of the base 1, a bearing plate 3 is provided on the top of the number of first shock-absorbing components 2, a placement plate 4 is fixedly installed on the top of the bearing plate 3, a boiler drum body 5 is fixedly installed on the top of the placement plate 4, and functional plates 7 are fixedly installed on both sides of the top of the base 1. Two sets of second shock-absorbing components 8 are provided inside the two functional plates 7.

[0023] The first damping assembly includes a damping adjustment cylinder 201, which is fixedly installed on the top surface of the base 1. A moving plate 202 is slidably installed inside the damping adjustment cylinder 201. A hinge support 203 is fixedly installed on the top of the moving plate 202. Two damping rods 204 are fixedly installed on the bottom of the moving plate 202. The bottom of the two damping rods 204 is fixedly installed on the inner bottom wall of the damping adjustment cylinder 201. Two inner shafts 205 are rotatably installed inside the damping adjustment cylinder 201. Worms 206 are fixedly installed at the rear ends of the two inner shafts 205, and the two worms 206 are located away from the damping adjustment cylinder. Worm gears 207 are engaged on one side of the inner wall of 201. A rotating shaft 208 is fixedly installed at the center of each of the two worm gears 207. A threaded rod 209 is fixedly installed on the top of each of the two rotating shafts 208. An adjusting screw 210 is threadedly installed on the surface of each of the two threaded rods 209. An adjusting plate 211 is fixedly installed on the top of each of the two adjusting screws 210. The two adjusting plates 211 move up and down along the surface of the two damping rods 204 respectively. A shock-absorbing spring 212 is sleeved on the top of the adjusting plate 211 outside the two damping rods 204. The upper and lower ends of the shock-absorbing spring 212 press against the moving plate 202 and the adjusting plate 211 respectively.

[0024] The second damping assembly includes a movable plate 801, a support rod 802, a hinge rod 803, a fixed seat 804, and a spring damper 805. The movable plate 801 is slidably installed inside the functional plate 7, and the movable plate 801 slides up and down along the interior of the functional plate 7. The upper part of the movable plate 801 is fixedly connected to the support rod 802, and the upper part of the support rod 802 is used to support the load-bearing plate 3. The bottom ends of the movable plate 801 are respectively hinged to the hinge rods 803, and the ends of the hinge rods 803 are respectively hinged to the sliders. The sliders are slidably installed inside the functional plate 7, and the sliders slide horizontally along the interior of the functional plate 7. Spring dampers 805 are respectively installed between the two sliders and the fixed seat 804. The fixed seat 804 is fixedly installed on the inner bottom surface of the functional plate 7. The top of the support rod 802 is fixedly connected to an L-shaped plate 6, and the L-shaped plate 6 is fixedly connected to the load-bearing plate 7.

[0025] like Figure 1As shown, by connecting the hinge support 203 and the bearing plate 3 in a hinged manner, stress concentration and structural damage caused by rigid connection are avoided when the bearing plate 3 experiences irregular vibration. This design allows the bearing plate 3 to move freely to a certain extent through the hinge point when subjected to impact or vibration. By extending the inner shaft 205 to the outside of the shock-absorbing adjustment cylinder 201, it is convenient for operators to operate the inner shaft 205.

[0026] like Figure 5 As shown, by setting a second shock-absorbing component 8, which includes a movable plate 801, a support rod 802, a hinge rod 803, a fixed seat 804, and a spring damper 805, etc., when the boiler drum body 5 vibrates, it will drive the bearing plate 3 to vibrate. The bearing plate 3 drives the support rod 802 to vibrate through the L-shaped plate 6. The support rod 802 transmits the vibration to the movable plate 801 below. The movable plate 801 moves downward under pressure. Through the cooperation of the hinge rod 803 and the fixed seat 804, the spring damper 805 is squeezed. Through the buffering and damping effect of the spring damper 805, the first shock-absorbing component is assisted in the shock absorption of the boiler drum body 5.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, by means of the cooperation between the inner shaft 205 and the worm gear 206 and other components, the compression degree of the shock absorber spring 212 is precisely adjusted;

[0029] 2) Subsequently, the vibration generated during the operation of the boiler drum body 5 will be transmitted to the moving plate 202 through the bearing platform and hinge support 203.

[0030] 3) The vibration transmitted to the moving plate 202 is then effectively absorbed and offset by the synergistic effect of the damping rod 204 and the shock-absorbing spring 212, thereby achieving the purpose of vibration reduction;

[0031] 4) Finally, by configuring a second damping component, it can work together with the first damping component to exert a damping effect, thereby significantly improving the overall damping effect.

[0032] In summary, this boiler drum support, by incorporating a first damping component, allows for adjustment of the compression degree of the damping spring 212 by rotating the inner shaft 205. The rotation of the inner shaft 205 drives the worm gear 206 to rotate, which in turn meshes with the worm wheel 207, causing the threaded rod 209 to rotate. The rotation of the threaded rod 209 causes the adjusting inner cylinder to displace vertically, thereby causing the adjusting plate 211 to slide along the surface of the damping rod 204, thus compressing or releasing the damping spring 212. This design allows for flexible adjustment of the compression degree of the damping spring 212 according to the damping requirements of different boiler drum specifications, demonstrating strong practicality.
