Description

Technical Field

[0001] This utility model relates to the field of vertical tower technology, specifically to a vertical tower stabilizer. Background Technology

[0002] Vertical towers are commonly used equipment in chemical production. These towers are considered tall structures. For self-supporting steel towers with a skirt base where the ratio of height H to diameter D is greater than 5 and the height exceeds 10m, stability and safety must be fully considered during the design process.

[0003] Generally, the taller the tower and the larger the ratio of tower height (H) to tower diameter (D), the greater the bending stress on the shell. For vertical towers containing liquids and equipped with long-shaft agitators, in addition to conventional loads such as gravity, temperature, wind, and seismic loads, they are also affected by the impact of moving fluids and eccentric loads, which further exacerbates the swaying phenomenon at the top of the tower. When the sway value consistently exceeds the allowable value, it can, at best, affect the normal operation of the agitator inside the tower; at worst, it can cause fatigue damage to the welds of the tower body, especially the circumferential welds, and even lead to tower tilting or collapse. Utility Model Content

[0004] In view of this, the present invention aims to provide a vertical tower stabilizer that can effectively reduce excessive swaying of the tower under extreme conditions and improve the safety of the tower in use.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: This utility model provides a vertical tower stabilizer, including a shock-absorbing block, a guide sleeve, a steel pipe, a U-bolt, a connecting seat, a sealing plate, a long plate, a hexagonal bolt, a hexagonal nut, and an ear plate. The guide sleeve is fixedly connected to one end of the steel pipe. The shock-absorbing block is installed inside the guide sleeve. The steel pipe is connected to the long plate by the U-bolt and fixed to the long plate by the U-bolt. The long plate is fixedly connected to the connecting seat. The other end of the steel pipe is fixedly connected to the sealing plate. The ear plate is fixedly connected to the connecting seat. The ear plate has a threaded hole matching the hexagonal bolt. The hexagonal bolt passes through the hexagonal nut and the threaded hole on the ear plate and abuts against the sealing plate. It is locked by rotating the hexagonal nut. The connecting seat is connected to the external tower top cover.

[0006] Furthermore, the number of U-bolts is at least two.

[0007] Furthermore, the number of the elongated plates is the same as the number of the U-bolts.

[0008] Furthermore, the guide sleeve is fixedly connected to one end of the steel pipe by welding.

[0009] Furthermore, the other end of the steel pipe is fixedly connected to the sealing plate by welding.

[0010] Furthermore, the shock absorber block is made of one of the following materials: polyurethane, hard rubber, or soft polytetrafluoroethylene.

[0011] The beneficial effects of this utility model are as follows: (1) The vertical tower stabilizer of this utility model is generally used in groups. The end damping block is preferably made of materials with moderate elasticity, such as polyurethane, hard rubber, soft polytetrafluoroethylene, etc. Such materials have good shock absorption effect and excellent support, fatigue resistance and weather resistance. This avoids the phenomenon of uneven force of multiple stabilizers due to thermal expansion and contraction to a certain extent, and avoids the phenomenon of individual stabilizers being deformed due to excessive force, failure due to excessive gap, or local damage to columns and beams.

[0012] (2) By adjusting the hexagonal bolts, the distance between the shock absorber and the surrounding columns and beams can be controlled, thereby effectively reducing the phenomenon of excessive swaying of the tower body under extreme conditions such as excessive wind speed, foundation vibration, fluid impact, and eccentric load. This reduces the risk of weld fatigue, tilting, and collapse of the tower body, and improves the safety of the tower body.

[0013] (3) The steel pipe of the vertical tower stabilizer of this utility model can be moved after the U-bolt is removed. When the shock absorber is worn too much or fails due to aging, the shock absorber can be replaced by removing the U-bolt and moving the steel pipe to the center area of ​​the tower. There is no need to operate outside the safe area of ​​the tower, which further ensures the safety of operation.

[0014] (4) This utility model has a simple structure and is easy to install. This utility model is generally used in groups and makes soft contact with the surrounding columns and beams. When the surrounding columns and beams are circular, the number of stabilizers is at least 3 and they are evenly distributed around the circumference. When the surrounding columns and beams are rectangular, the number of stabilizers is at least 4 and they are distributed in a cross shape. Attached Figure Description

Detailed Implementation

[0016] To gain a more detailed understanding of the features and technical content of this utility model, the implementation of this utility model will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit this utility model.

[0017] like Figure 1-2 As shown, a vertical tower stabilizer includes a shock absorber 1, a guide sleeve 2, a steel pipe 3, two U-bolts 4, a connecting seat 5, two elongated plates 6, a sealing plate 7, an ear plate 8, hexagonal bolts 10, and hexagonal nuts 9. The guide sleeve 2 is fixedly connected to one end of the steel pipe 3 by welding. The shock absorber 1 is installed inside the guide sleeve 2. The two U-bolts 4 fix the steel pipe 3 to the two elongated plates 6 respectively. The steel pipe 3 is fixed to the two elongated plates 6 by the two U-bolts 4. The elongated plates 6 and the U-bolts 4 can cooperate to circumferentially enclose and fix the steel pipe 3. The two elongated plates 6 are fixedly connected to the connecting seat 5 by welding.

[0018] The other end of the steel pipe 3 is fixedly connected to the sealing plate 7 by welding. The ear plate 8 is fixedly connected to the connecting seat 5. The ear plate 8 has a threaded hole that matches the hexagonal bolt 10. The hexagonal bolt 10 passes through the hexagonal nut 9 and the threaded hole on the ear plate 8 in sequence and abuts against the sealing plate 7. It is locked by tightening the hexagonal nut 9. The steel pipe 3 can be moved by adjusting the hexagonal bolt 10, which can eventually drive the shock absorber 1 to move slightly outward from the tower. The connecting seat 5 is connected to the top cover of the external tower body by welding, so that the vertical tower stabilizer is fixed above the tower body and plays a stabilizing role.

[0019] The shock absorber 1 is preferably made of a material with moderate elasticity, such as polyurethane, hard rubber, or soft polytetrafluoroethylene.

[0020] The working principle of this utility model: The vertical tower stabilizer of this utility model is generally used in groups. When the surrounding columns and beams are designed to be circular, the number of vertical tower stabilizers is at least 3, and they are evenly distributed around the circumference of the tower body. When the surrounding columns and beams are designed to be rectangular, the number of vertical tower stabilizers is at least 4, and they are distributed in a cross shape. By adjusting the position of the steel pipe 3 by adjusting the hexagonal bolts 10, the damping block 1 can be moved slightly, which can control the distance and contact degree between the damping block 1 and the surrounding columns and beams, thereby effectively reducing the excessive swaying of the tower body under extreme conditions such as excessive wind speed, foundation vibration, fluid impact, and eccentric load. This reduces the risk of weld fatigue, tilting, and collapse of the tower body, and improves the safety of the tower body. When the damping block 1 shows excessive wear or aging failure, the damping block 1 can be replaced by removing the U-bolts 4 and moving the steel pipe 3 to the center area of ​​the tower body, without having to operate outside the safe area of ​​the tower body, further ensuring the safety of operation. The moderately soft and hard elastic damping block 1 has excellent shock absorption, support, fatigue resistance and weather resistance. This, to a certain extent, avoids the phenomenon of uneven stress on the stabilizer caused by thermal expansion and contraction, and avoids adverse phenomena such as stabilizer deformation, support failure or damage to columns and beams.

[0021] Here, the specific models of the devices mentioned above are not limited or described in detail, and the in-depth connection methods of the devices mentioned above are not described in detail, as they are common knowledge and can be understood by those skilled in the art.

[0022] This utility model embodiment is merely an illustration of its specific implementation and is not intended to limit its scope of protection. Those skilled in the art can make certain modifications based on this embodiment; therefore, all equivalent changes or modifications made in accordance with the scope of this utility model patent claim fall within the scope of this utility model patent claim.
