Description

Technical Field

[0001] The invention relates to the technical field of fire resistance of a sling anchor cup, and more particularly to a sling anchor cup protective cover with dehumidification and drying functions. Background Art

[0002] The cable system (main cable, slings, etc.) of a suspension bridge is the key force-bearing structure of a cable system bridge, commonly known as the "lifeline" of the bridge. Ensuring the safety and durability of the cable system is the top priority in the construction and operation of a cable system bridge. Most of the main cables and slings of suspension bridges have been subjected to relevant fire-resistant, heat-insulating and sealing protection. Since the anchor cup of the sling is poured with a zinc-copper alloy with a melting point of about 400°C and the anchor cup of this sling has not yet been subjected to fire-resistant, heat-insulating and sealing protection.

[0003] Therefore, in order to significantly improve the disaster prevention and corrosion resistance of cable system bridges, ensure the safety and stability of cable system bridges, extend the safe operation life of bridges, and ensure the safe and efficient operation of bridges during the operation period, the protection of the cable anchor cup is of great significance. Therefore, in order to solve this problem, a fire-resistant cover can be set on the outside of the cable anchor cup.

[0004] However, during the experimental trial, it was found that the cable connected to the top of the sling anchor cup is at the bottom of the entire cable. The basic structure of the existing cables includes an internal steel core and an external protective layer, which often causes water accumulation at the bottom of the cable. This type of problem is often caused by many reasons such as the cold and hot liquefaction of the steel core, or external rainwater leakage. Therefore, in order to overcome this problem, a hole is opened in the protective layer of the cable at the connection with the sling anchor cup to drain the accumulated water, but this causes the accumulated water to enter the interior of the fire-resistant cover, which will also have an adverse effect.

[0005] Therefore, providing a sling anchor cup protection structure that can balance the fire resistance and dehumidification and drying effects is an urgent problem that needs to be solved by those skilled in the art. Summary of the invention

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See attached Figure 1 The embodiment of the present invention discloses a sling anchor cup protective cover with dehumidification and drying functions, wherein the protective layer side wall at the bottom end of the cable 2 connected to the sling anchor cup 1 is symmetrically provided with drainage holes, and a joint pipe 3 is inserted into the drainage hole; the protective cover comprises:

[0060] Water diversion and storage parts 4; there are two water diversion and storage parts 4, which include a water diversion pipe 41 and a water storage pipe 42; one end of the water diversion pipe 41 is plugged with the joint pipe 3, and the other end is inclined toward the lower part of the outer side of the cable 2; the middle part of the water storage pipe 42 is connected with the end of the water diversion pipe 41 away from the cable 2, and the two ends of the water storage pipe 42 are connected with the air inlet pipe 43 and the air outlet pipe 44 which are vertically upward;

[0061] The sealing cover body 5 is a cylindrical body with openings at both ends, and is sealed and wrapped and fixed on the outside of the sling anchor cup 1 and the water guide and storage member 4; the inner surface of the sealing cover body 5 has a sealing fire-resistant layer 7; an isolation gap 51 is formed between the sealing cover body 5 and the sling anchor cup 1;

[0062] Dehumidification system 6; the dehumidification system 6 has a main air pipe 61 extending into the isolation gap 51, and the main air pipe 61 has a bronchial pipe 62 connected to the air inlet pipe 43; the sealing cover body 5 has an air inlet valve connected to the main air pipe 61, and an exhaust valve installed on the sealing cover body 5.

[0063] See attached Figure 7 The top end of the air inlet pipe 43 is connected to the bronchus 62 through the flow control valve 45.

[0064] The water diversion pipe 41 includes a joint section 411, a slope section 412 and a connection section 413 which are connected in sequence; the outer wall of the joint section 411 has a sealing ring and is inserted into the inner side of the joint pipe 3; the joint section 411 and the connection section 413 are both arranged horizontally, and the height of the connection section 413 is lower than that of the joint section 411.

[0065] In this embodiment, a flow control valve 45 is provided to regulate the gas flow and flow rate into the water storage pipe 42. The regulation standard is: when water is stored in the water storage pipe 42, the gas will neither flush the water out of the gas outlet pipe 44 nor flush the water back to the drain port, so that dehumidification can be achieved without affecting the internal structure of the isolation gap 51. The regulation of the gas flow and flow rate can be debugged in advance, and the regulation can be performed by placing an appropriate amount of water in the water storage pipe 42. Therefore, in this embodiment, in order to meet the visibility of the adjustment, the overall structure of the water guide and storage member 4 can be made of a transparent plastic material. Example 2

[0066] See attached Figure 5 and attached Figure 6 The water storage pipe 42 is a semicircular tube. The semicircular tubes of the two water diversion and storage parts 4 are symmetrically arranged on both sides of the cable 2, and there are gaps at the corresponding ends; the ends of the semicircular tubes have hanging rings 421, and a tension spring 46 is stretched between the corresponding two hanging rings 421.

[0067] In order to further optimize the above technical solution, a perforated plate 47 is provided at the top opening of the air outlet pipe 44 .

[0068] In this embodiment, the gas flow rate and flow rate of the flow control valve 45 can be set in advance by experiment. Figure 7The water-introducing and storing component 4 provided in the invention is placed on a horizontal plane, and then a proper amount of water is placed in the water storage pipe 42 to adjust the amount of water. At this time, it is visible whether the connecting section 413 and the air outlet pipe 44 are discharging water. Therefore, in order to improve the overall structural strength, the overall structure of the water-introducing and storing component 4 can be made of an iron pipe to make it more stable. Moreover, in order to improve the stability and shock-absorbing effect, the two water storage pipes 42 are connected by a tension spring 46. On the one hand, they form a whole to improve stability. On the other hand, they can reduce shock and prevent vibration from affecting the airflow.

[0069] Since the cable 2 will vibrate in real time, the airflow adjustment method of embodiment 1 is directly performed on the suspension anchor cup 1, including the vibration effect, and the effect will be better. If the experimental method of this embodiment is adopted, the corresponding vibration frequency should be added during debugging, that is, a vibrator should be added to meet the actual site needs. Otherwise, although the airflow will not flush water out of the air outlet pipe 44 or flush water back to the drain port in a static state, once there is a vibration effect, the sputtering of the water flow will be unstable, affecting the final effect. Example 3

[0070] See attached Figure 1 The dehumidification system 6 also includes a dehumidifier, and the dry gas outlet of the dehumidifier is connected to the air inlet valve through a hose, and a one-way valve is installed on the hose.

[0071] In order to further optimize the above technical solution, the main air pipe 61 extends from the bottom of the sealing cover body 5 to the top thereof, and is attached to the inner wall of the sealing cover body 5; the exhaust valve is installed at the bottom of the sealing cover body 5.

[0072] The present embodiment utilizes a dehumidifier to produce dry air with a certain pressure, and the dry air is transported to the sealing cover body 5 through relevant pipelines. The dry air circulates in the isolation gap 51 between the sealing cover body 5 and the sling anchor cup 1, and takes away the wet air in the sealing cover body 5 and discharges it into the atmosphere. At the same time, the wet gas is continuously discharged from the air outlet pipe 44 and is taken away together, ensuring that the air humidity in the sealing cover body 5 is maintained below 45%, thereby avoiding or slowing down the corrosion of the sling anchor cup 1 and the steel wire inside it.

[0073] A dehumidifier and related pipelines are installed in the bridge deck inspection road at the lowest point of the mid-span main cable. After the dehumidification pipeline is connected to the dehumidifier, it is extended along the fork-shaped ear plate at the bottom of the sling toward the main towers on both sides, and the dry air with a slight positive pressure in the dehumidification pipeline is sent to the upper end of the sealing cover body 5. The dry air flows from the upper end to the lower end inside the sealing cover body 5 and is discharged through the exhaust valve at the bottom, taking away the wet air in the sealing cover body 5, ensuring that the air humidity in the sealing cover body 5 is maintained below 45%, thereby realizing dehumidification protection for the bottom of the sling and the sling anchor cup 1. Example 4

[0074] See attached Figure 2 To Attachment Figure 4 The sealing fireproof layer 7 includes two layers of flame retardant and fireproof sealant coating layers 71 , and a composite fiber fireproof insulation belt 72 bonded between the two layers of flame retardant and fireproof sealant coating layers 71 .

[0075] The sealing cover body 5 comprises two half shells 52 equally divided along the plane where the axis thereof lies. The edges of the butt joints of the half shells 52 are provided with flange plates 53 protruding outwards. The two half shells 52 are connected to the two flange plates 53 which are butt jointed by bolts 54 .

[0076] A rubber sealing strip is embedded in the butt joint edges of the two half shells 52 ; and a flame retardant and fire resistant sealant is coated on the butt joint edges of the two half shells 52 .

[0077] In this embodiment, the sealing cover body 5 is made of 304 stainless steel with a thickness of 3 mm. The flame retardant fire-resistant sealant coating layer 71 and the flame retardant fire-resistant sealant are both made of B-FRS flame retardant silica gel; the composite fiber fire-resistant insulation belt 72 is made of aerogel composite insulation felt HLGX-853, which is made of nano-silicon dioxide aerogel as the main raw material and glass fiber as the reinforcing material. The thickness of the two layers of flame retardant fire-resistant sealant coating layer 71 is 1000 μm. The thickness of the composite fiber fire-resistant insulation belt 72 is 4±1 mm.

[0078] The sealing cover body 5 and the sealing fire-resistant layer 7 of this embodiment are constructed according to the following process and sequence:

[0079] ① Cleaning the inner surface of the sealing cover body 5: Remove dirt, such as dust, oil, etc., from the inner surface of the sealing cover body 5 until the inner surface of the sealing cover body 5 is clean and dry.

The thickness of the flame retardant and fire resistant sealant coating is about 1000μm. Be careful not to have any phenomenon such as missing coating and bubbling.

[0081] ③ Construction of composite fiber fire-resistant insulation belt 72, referred to as FCFR fireproof belt: stick the FCFR fireproof belt on the first flame retardant fireproof sealant coating layer 71 scraped on the inner surface of the sealing cover body 5, and the joints should be tight and neat without obvious gaps.

[0082] ④ Scrape the second flame retardant and fire resistant sealant coating layer 71: After the construction of the FCFR fire resistant belt is completed, scrape the second flame retardant and fire resistant sealant, and use a special scraper to scrape the flame retardant and fire resistant sealant onto the surface of the FCFR fire resistant belt. The thickness of the flame retardant and fire resistant sealant coating is about 1000μm. Note that in order to make the finished product look beautiful, the surface of the second flame retardant and fire resistant sealant should be uniform, smooth and free of defects after construction, and pinholes, cracks, shedding, missing coating, etc. are not allowed.

[0083] ⑤ Install a rubber sealing strip on the butt joint surface of the stainless steel sealing cover body 5, and then apply flame retardant and fire resistant sealant on all butt joint surfaces.

[0084] In this embodiment, in order to avoid the installation position of the water-guiding and storing component 4, the sealing cover body 5 is designed as a cylindrical barrel structure. During installation, the joint pipe 3 is first inserted into the seal at the drain outlet. To ensure firmness, the joint pipe 3 can be bonded and fixed to the drain outlet. Then the connecting section 413 of the water-guiding and storing component 4 is inserted into the inner side of the joint pipe 3, and then a tension spring 46 is hung at the end of the water storage pipes 42 of the two water-guiding and storing components 4. Finally, the main air pipe 61 and the bronchial pipe 62 are connected.
