[0080] Please refer to Figures 1 to 6 , this embodiment relates to a suction pipe 4 of a suction device, wherein the suction device in this embodiment is a suction excavator; the suction pipe 4 includes:

[0081] Inner rubber layer 41; the inner rubber layer 41 is a key component in the structure of the suction pipe 4. It directly contacts the conveying medium, such as water, gas, bricks, steel bars, etc. Therefore, it needs to have good compactness and adaptability to ensure that the suction pipe 4 can withstand a certain pressure and also protect the reinforcing layer 44 from damage, thereby ensuring the overall performance and service life of the suction pipe 4. Therefore, the inner rubber layer 41 in this embodiment is a styrene-butadiene rubber layer, and the styrene-butadiene rubber layer is a synthetic rubber foam body, which has a delicate, soft, elastic feel, and has the characteristics of shock absorption, heat preservation, water impermeability, air impermeability, etc.

[0082] Cord fabric layer 42, the cord fabric layer 42 is wound around the outer surface of the inner rubber layer 41. During the winding process, the winding should be flat without wrinkles and there should be no gaps. The cord fabric layer 42 is a high-strength fiber cord fabric layer 42; the function of the cord fabric layer 42 in the suction pipe 4 is to improve the bearing capacity and seismic resistance of the suction pipe 4. The cord fabric layer 42 serves as the main skeleton of the suction pipe 4. After being mutually fused, it forms a skeleton. This structure not only enhances the physical strength of the suction pipe 4 but also improves its durability and stability.

[0083] The reinforcing layer 44 is wound around the outer surface of the cord layer 42; during the winding process, the winding should be smooth and wrinkle-free, and the winding should be seamless. Specifically, in the present embodiment, the reinforcing layer 44 is a high-strength steel wire winding layer. The role of the steel wire winding layer in the suction pipe 4 is mainly to enhance the pressure resistance and wear resistance of the suction pipe 4. The steel wire winding layer forms a solid reinforcing layer 44 by winding high-strength steel wire. This reinforcing layer 44 is located between the inner tube wall and the outer tube wall of the suction pipe 4. This structure not only improves the pressure resistance of the suction pipe 4, but also enhances its wear resistance, so that the suction pipe 4 can maintain good performance under high pressure and wear environment, and can adapt to the extraction of building materials such as tiles, bricks, cement steel bars, soil, etc. The setting of the steel wire winding layer enables the suction pipe 4 to withstand higher pressure and stronger wear, thereby extending the service life of the suction pipe 4.

[0084] The copper wire layer 45 is wound around the outer surface of the reinforcing layer 44; during the winding process, the winding should be smooth and wrinkle-free, and the winding should be seamless. The function of the copper wire layer 45 in the suction tube 4 is to provide a skeleton structure to enhance the pressure-bearing strength and bending performance of the suction tube 4. The copper wire layer 45 in the suction tube 4 is formed by cross-spiral winding of multiple copper wires. This structure not only provides the strength and rigidity of the suction tube 4, but also enables the suction tube 4 to have good bending performance and maintain a stable shape at different angles. The use of copper wires enables the suction tube 4 to maintain good elasticity when under pressure, thereby ensuring the reliability and durability of the suction tube 4 during use.

[0085] and an outer rubber layer 47, the outer rubber layer 47 is wound on the outer surface of the copper wire layer 45, and the winding process should be smooth without wrinkles and gaps. The outer rubber layer 47 is made of natural rubber, which has excellent corrosion resistance and good pressure resistance. The natural rubber outer rubber layer 47 can withstand a large pressure and will not break due to excessive pressure, thereby ensuring the stability and reliability of the connection of the suction pipe 4 and improving the durability and reliability of the suction pipe 4.

[0086] Specifically, the suction pipe 4 of the suction device in this embodiment includes, from the inside to the outside, an inner rubber layer 41, a cord fabric layer 42, a reinforcing layer 44, a copper wire layer 45, and an outer rubber layer 47 in sequence. It is composed of multiple layers of structures, which play a protective role for the suction pipe 4. Among them, the inner rubber layer 41 is the innermost layer of the suction pipe 4. The inner rubber layer 41 needs to have good compactness and adaptability to ensure that the suction pipe 4 can withstand a certain pressure and also protect the reinforcing layer 44 from damage, thus ensuring the overall performance and service life of the suction pipe 4. The outer rubber layer 47 is the outermost layer of the suction pipe 4. The outer rubber layer 47 can withstand a relatively large pressure and will not rupture due to excessive pressure, ensuring the stability and reliability of the connection of the suction pipe 4 and improving the durability and reliability of the suction pipe 4. And between the inner rubber layer 41 and the outer rubber layer 47, there are a cord fabric layer 42, a reinforcing layer 44, and a copper wire layer 45, which greatly improve the load-bearing capacity and seismic resistance of the suction pipe 4, strengthen the pressure resistance and wear resistance of the suction pipe 4, enhance the bearing strength and bending performance of the suction pipe 4, can adapt to extracting building materials such as tiles, bricks, cement steel bars, and soil, avoid or reduce the wear and rupture of the suction pipe 4, improve the service life of the suction pipe 4, and avoid affecting the emergency rescue efficiency due to the damage of the suction pipe 4.

[0087] Optionally, in some embodiments, such as Figure 6 shown, the suction pipe 4 of the suction device further includes a first middle rubber layer 43. The first middle rubber layer 43 is wound around the outer surface of the cord fabric layer 42, and the reinforcing layer 44 is wound around the outer surface of the first middle rubber layer 43. Specifically, the suction pipe includes, from the inside to the outside, an inner rubber layer 41, a cord fabric layer 42, a first middle rubber layer 43, a reinforcing layer 44, a copper wire layer 45, and an outer rubber layer 47 in sequence. It is composed of multiple layers of structures, which play a protective role for the suction pipe 4. Among them, the first middle rubber layer 43 is located between the cord fabric layer 42 and the reinforcing layer 44, increasing the durability and service life of the suction pipe 4, protecting the reinforcing layer from damage, and having a waterproof and moisture-proof effect on the reinforcing layer 44.

[0088] Optionally, in some embodiments, such as Figure 6As shown, the suction pipe 4 of the suction device further includes a second intermediate rubber layer 46 wound around the outer surface of the copper wire layer 45, and the outer rubber layer 47 is wound around the outer surface of the second intermediate rubber layer 46.

The first intermediate rubber layer 43 is located between the cord fabric layer 42 and the reinforcing layer 44, and the second intermediate rubber layer 46 is located between the copper wire layer 45 and the outer rubber layer 47. By providing the first intermediate rubber layer 43 and the second intermediate rubber layer 46, the durability and service life of the suction pipe 4 are increased, the reinforcing layer and the copper wire layer 45 are protected from damage, and the reinforcing layer 44 and the copper wire layer 45 are waterproof and moisture-proof.

[0092] A driving mechanism 2, the driving mechanism 2 is connected to the movable boom assembly 1, and the driving mechanism 2 is used to drive the movable boom assembly 1 to extend or contract. By driving the movable boom assembly 1 to extend through the driving mechanism 2, the suction pipe 4 on the movable boom assembly 1 is driven to extend, thereby expanding the operation range of the suction pipe 4.

[0093] A damage prevention mechanism 3, the damage prevention mechanism 3 is arranged on the movable boom assembly 1, and the damage prevention mechanism 3 is connected to the movable boom assembly 1; the suction pipe 4 passes through the damage prevention mechanism 3 and adheres to the movable boom assembly 1, and the damage prevention mechanism 3 is used to limit the suction pipe 4 to prevent the suction pipe 4 from slipping off the movable boom assembly 1 and prevent the suction pipe 4 from being worn. By providing the damage prevention mechanism 3 on the movable boom assembly 1, the suction pipe 4 is prevented from being worn during the extension process of the movable boom assembly 1, avoiding or reducing the cracking or damage of the suction pipe 4, improving the service life of the suction pipe 4, and avoiding affecting the emergency rescue efficiency due to the cracking or damage of the suction pipe 4.

[0094] Specifically, for the suction device 300 of the suction equipment in this embodiment, during the emergency rescue operation, the suction pipe 4 passes through the anti-wear mechanism 3 and adheres to the movable boom assembly 1 to prevent the suction pipe 4 from slipping off the movable boom assembly 1. The driving mechanism 2 drives the movable boom assembly 1 to extend, thereby driving the suction pipe 4 on the movable boom assembly 1 to extend, thus expanding the working range of the suction pipe 4. Since the anti-wear mechanism 3 is provided on the movable boom assembly 1, it prevents the suction pipe 4 from being worn during the extension of the movable boom assembly 1, avoids or reduces the cracking or damage of the suction pipe 4, improves the service life of the suction pipe 4, and avoids affecting the emergency rescue efficiency due to the cracking or damage of the suction pipe 4.

[0095] Specifically, in this embodiment, as Figures 1 to 5 shown, there are multiple anti-wear mechanisms 3, and the multiple anti-wear mechanisms 3 are respectively arranged at intervals on the movable boom assembly 1. The multiple anti-wear mechanisms 3 are respectively connected to the movable boom assembly 1, and the suction pipe 4 passes through the multiple anti-wear mechanisms 3 and adheres to the movable boom assembly 1. Specifically, by providing multiple anti-wear mechanisms 3 on the movable boom assembly 1 and arranging the multiple anti-wear mechanisms 3 at intervals, the anti-wear effect on the suction pipe 4 is achieved in multiple directions, thereby further preventing the suction pipe 4 from being worn during the extension of the movable boom assembly 1, avoiding or reducing the cracking or damage of the suction pipe 4, improving the service life of the suction pipe 4, and avoiding affecting the emergency rescue efficiency due to the cracking or damage of the suction pipe 4. It should be noted that the number of the anti-wear mechanisms 3 is not limited in this embodiment and can be set according to actual needs.

[0096] Optionally, in some embodiments, as Figures 1 to 5 shown, the anti-wear mechanism 3 includes two anti-wear plates 31, two first guide rollers 32, and two second guide rollers 33; one of the anti-wear plates 31 is arranged on one side of the movable boom assembly 1, and the other anti-wear plate 31 is arranged on the other side of the movable boom assembly 1.
