Description

Technical Field

[0001] The invention relates to the technical field of earthquake-resistant hangers, in particular to a heavy-bearing and earthquake-resistant adaptive hanger. Background Art

[0002] According to relevant surveys, many earthquakes will cause economic losses and casualties, which are mainly caused by the collapse and destruction of buildings. Therefore, it is necessary to minimize the damage to buildings caused by earthquakes.

[0003] During earthquakes, pipes in buildings are often damaged, causing the pipelines they carry to fall and break, resulting in large economic losses and very likely casualties, which can easily lead to various chain reactions and pose a major safety hazard. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides an adaptive seismic hanger that realizes transverse and longitudinal seismic resistance just through the steel wire rope, thus solving the problems raised by the above-mentioned background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An adaptive seismic hanger includes an integrated hanger, which is a steel wire rope structure supported by a steel frame. Two expansion screws are installed on the top of the room, and a steel plate is fixed between the expansion screws. A first steel frame is welded on both sides of the plate. The steel wire rope is fixed to the first steel frame near the steel plate. Below the first steel frame, a horizontal second steel frame is fixed between the two steel wire ropes. The horizontal second steel frame is connected between the two steel wire ropes through a rope clamp. A third steel frame is fixed between the tail end of the first steel frame and the middle position of the second steel frame. The three steel frames form a balance system through the principle of leverage, so that the steel wire rope lifts the U-shaped bracket below, and fixed steel frames are installed on both sides of the U-shaped steel frame to prevent left and right displacement.

[0007] The rope clamp is composed of two identical and mutually staggered L-shaped rope clamps, which are respectively arranged at the two ends of the second steel frame to connect the second steel frame with the steel wire ropes at the two ends.

[0008] The rope clamp is connected to the second steel frame through threads.

[0009] The length of the first steel frame is 80 cm, the length of the second steel frame is 30 cm, and the length of the third steel frame is 30 cm.

[0010] The steel sleeve is connected to the first steel frame and the second steel frame through a sleeve connection, and the steel sleeve is connected to the third steel frame through a thread connection.

[0011] The first steel frame and the steel flat plate are fixed by welding.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The adaptive seismic hanger can achieve seismic resistance without destroying the existing civil engineering structure, making it have seismic resistance function.

[0014] 2. The adaptive seismic hanger uses steel wire rope as the main load-bearing component, which has obvious advantages in longitudinal and lateral seismic resistance compared with traditional seismic supports.

[0015] 3. The load-bearing capacity of the steel wire rope used in the adaptive seismic hanger is much greater than that of the steel frame of the same weight and volume. It can better resist earthquakes and adaptively respond to changes in loads when an earthquake occurs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0025] An adaptive seismic hanger includes an integrated hanger, which is composed of a bracket combination consisting of four steel wire ropes, at least two fixed brackets and two groups of three supporting steel frames. The steel wire ropes connect the steel plate fixed by the top expansion screws and the bracket supporting the pipeline. The fixed bracket prevents the pipeline from swinging left and right. The bracket combination ensures the force balance of the entire hanger system and ensures stability.

[0026] The bracket assembly comprises a first bracket (9) in the transverse direction, a second bracket (10) in the pipeline direction, and a third bracket (11) connected to the end of the first bracket (9) and the middle of the second bracket (10). The first bracket (9) is fixed to the plane of the top steel plate (3) through a welding point (2). The second bracket (10) is supported between two steel wire ropes (5) on one side and connected between the steel wire ropes (5) through an L-shaped rope clamp (13). The L-shaped rope clamp (13) is connected to the second bracket (10) through a thread (12). The third bracket (11) is connected to the first and second brackets (9, 10) through a steel sleeve (15). The end of the first bracket (9) has a larger diameter to prevent the steel sleeve (15) from falling off. The steel sleeve (15) is connected to the second bracket (10) through a thread.

[0027] The L-shaped rope clamp is composed of two L-shaped rope clamps that are engaged with each other through threads, and the steel wire rope passes through them, so that the steel wire rope is not easy to fall off.

[0028] The steel sleeve is a T-shaped steel component. The upper sleeve can be put on the bracket, and the lower part is connected to the third bracket through threads.

[0029] Preferably, the first bracket is an 80cm cylindrical steel bracket, and the second bracket and the third bracket are both 30CM cylindrical steel brackets.

[0030] Preferably, the steel wire rope is selected to have a specification of 6*19, a diameter of 9.5 mm, and a minimum breaking force of 53.4 KN.

[0031] Preferably, the steel frames are made of 42CrMo steel, which is subjected to a quenching and high-temperature tempering heat treatment to make the steel have high strength and toughness, not brittle fracture, and bend resistance.

There are also two inclined fixed brackets (6) connected to the top on both sides of the U-shaped bracket (7) to prevent the pipe from moving sideways.

[0034] Example 2

[0035] Please refer to Figure 1-6 , including a comprehensive bracket, a first bracket (9) and a top steel plate (3) are fixed by a welding point (2), the first bracket (9) and the third bracket (11) are connected by a steel sleeve (15), the steel sleeve sleeve is sleeved on the first bracket (9), and the steel sleeve threaded end (16) is connected to the third bracket (11); the second bracket (10) and the third bracket (11) are also connected by the steel sleeve (15), the steel sleeve sleeve is sleeved on the second bracket (10), and the steel sleeve threaded end (16) is connected to the third bracket (11); the second bracket (10) and the wire rope (5) are connected by an L-shaped rope clamp (13), and the L-shaped rope clamp (13) is connected to the second bracket (10) by a thread (12).

[0036] The working principle of the present invention is as follows:

[0037] The hanger, with the first, second, and third brackets acting as levers, forms a stable equilibrium system. As long as the first bracket remains stable and the second bracket remains stationary, the system maintains a stable force balance. Even if subjected to vibration, the entire system will return to equilibrium once all components stop vibrating. Therefore, the steel frame is constructed of 42CrMo steel, a material known for its toughness and resistance to bending. The steel wire ropes offer excellent load-bearing performance and are less susceptible to earthquake damage than traditional steel frames, ensuring the integrity of pipelines and buildings.
