Description

Technical Field

[0001] This utility model relates to the field of airport lighting auxiliary facilities technology, and in particular to an accelerated curing device for the pavement adhesive of airport embedded lighting bases suitable for low-temperature environments. Background Technology

[0002] Recessed lighting fixtures in airport navigation lighting systems primarily provide navigation guidance and safety assurance. Most of these fixtures are located on airport runways or taxiways, directly bearing the weight of aircraft tires; therefore, their installation stability directly impacts aircraft safety. The base of these recessed lights needs to be securely connected to the runway foundation structure during installation, and pavement adhesive is injected to enhance structural stability and prevent loosening or damage due to temperature changes, vibration, or external environmental disturbances. However, the pavement adhesive requires a certain curing time. Insufficient curing time can lead to unstable connections between the light fixture base and the asphalt or concrete pavement, making it prone to detachment or damage during high-speed aircraft taxiing, seriously threatening flight safety. The curing time of the pavement adhesive depends not only on the properties of the adhesive itself but also on the ambient temperature. Testing shows that the lower the ambient temperature, the longer the curing time for the pavement adhesive.

[0003] During routine construction or when installing or repairing recessed lighting fixtures at temperatures above 10°C, the pavement adhesive is typically allowed to cure naturally. However, in emergency situations, such as airport repairs, hot air guns or blowtorches are often used to accelerate the curing process and shorten the curing time. But this approach presents the following problems:

[0004] Firstly, when the temperature is below 10℃, conventional pavement adhesives cannot be used, and only fast-grade pavement adhesives produced abroad can be used, which greatly increases the construction cost; and taking an ambient temperature of 0℃ as an example, the curing time required for fast-grade pavement adhesives produced abroad is 40 minutes.

[0005] Secondly, it cures naturally when the temperature is above 10℃. Taking an ambient temperature of 10℃ as an example, the curing time is 55 minutes. During emergency repairs or nighttime construction without interrupting operations, sufficient curing time needs to be allowed, which significantly shortens the effective working time and affects airport operations.

[0006] Thirdly, when using hot air guns or blowtorches to accelerate the curing speed and shorten the curing time of pavement adhesive, the heating temperature is difficult to control because a closed working area cannot be formed on the construction site. Excessive temperature may cause the pavement adhesive on the lamp base to fail, and operation is inconvenient, increasing the difficulty of construction. Furthermore, improper use of hot air guns and blowtorches may also cause fires, further threatening airport operational safety.

[0007] In summary, in winter or cold regions (where temperatures drop below 10°C), the curing time of pavement adhesive is prolonged or renders it unusable during recessed lighting installations. This affects the maintenance and installation of lighting fixture bases, airport operational time, and ultimately, airport safety. Furthermore, during airport repairs, using existing hot air guns or blowtorches to accelerate adhesive curing and shorten curing time is difficult to control. Excessive temperatures can cause adhesive failure in the lighting fixture bases, and the process is inconvenient, increasing construction difficulty and posing safety hazards. Therefore, shortening the curing time of pavement adhesive after lighting fixture application, ensuring rapid curing in harsh environments and meeting operational standards, is of paramount importance. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an accelerated curing device for the pavement adhesive of the airport embedded lighting fixture base, which is mainly used for the installation of embedded lighting fixtures in low-temperature environments, so as to shorten the curing time of the pavement adhesive and is suitable for the purpose of potting and installing embedded lighting fixtures in various low-temperature environments.

[0009] This utility model discloses an accelerated curing device for pavement adhesive of airport embedded lighting fixture bases, comprising a cylindrical body with an opening at the lower end covering the lighting fixture installation and adhesive filling area. The cylindrical body contains a mounting bracket fixedly connected to the top of the cylindrical body. The mounting bracket includes a vertical rod with an upper top plate connected to the top of the cylindrical body at its upper end and a lower bottom plate at its lower end. The side of the vertical rod has a first mounting platform and a second mounting platform arranged along its length. The first mounting platform has a dehumidifier, and the second platform has a circulating fan. A heater is located above the lighting fixture installation and adhesive filling area below the lower bottom plate.

[0010] Furthermore, it also includes a controller and a temperature and humidity sensor. The controller is located at the top of the cylinder. The dehumidifier, the circulating fan, and the heater are electrically connected to the controller. The controller is also electrically connected to a temperature and humidity sensor. The detection end of the temperature and humidity sensor extends through the top of the cylinder and into the cylinder body.

[0011] As a preferred embodiment, the controller is covered by a housing, which has an inlet and an outlet for the power cord to pass through.

[0012] Furthermore, the sidewall of the cylinder includes an inner sidewall and an outer sidewall made of stainless steel, with an insulation layer provided between the inner sidewall and the outer sidewall.

[0013] Furthermore, the outer edge of the opening is provided with a sealing ring for sealing the junction between the cylinder and the ground, and the sealing ring is arranged circumferentially around the opening at the lower end of the cylinder.

[0014] As a preferred embodiment, the sealing ring is a silicone sealing ring.

[0015] Furthermore, the outer wall of the cylinder is provided with a wear-resistant and anti-slip layer.

[0016] Furthermore, the cylinder is provided with handles, and two handles are symmetrically arranged on both sides of the cylinder.

[0017] The beneficial effects of this utility model are as follows: The device covers the lamp installation and glue-filling area with a cylinder with an open lower end, forming a closed space between the cylinder and the lamp installation and glue-filling area to heat the lamp installation and glue-filling area. In use, the heater heats the closed space formed by the cylinder and the road surface around the lamp installation and glue-filling area. The circulating fan inside the cylinder accelerates the air circulation in the closed space, making the air temperature inside the device more uniform. The dehumidifier controls the humidity in the closed space, ensuring that the environmental parameters in the closed space match the curing requirements of the pavement glue, accelerating the curing speed of the pavement glue, and shortening the curing time required for the pavement glue, making it suitable for the installation or emergency repair of embedded lamps in low temperature, severe cold, rain and snow conditions.

Detailed Implementation

[0025] The present invention will be further described below.

[0026] This utility model provides an accelerated curing device for the pavement adhesive of an airport embedded lighting fixture base, mainly used for embedded lighting fixture installation in low-temperature environments. It includes a cylindrical body 1 with an opening 11 at its lower end, covering the lighting fixture installation and adhesive filling area 7. An installation bracket 2, fixedly connected to the top of the cylindrical body 1, is located inside the cylindrical body 1. The installation bracket 2 includes a vertical rod 22, with an upper top plate 21 connected to the top of the cylindrical body 1 at its upper end and a lower bottom plate 23 at its lower end. A first installation platform 221 and a second installation platform 222, arranged along the length of the vertical rod 22, are located on the side of the vertical rod 22. A dehumidifier 31 is installed on the first installation platform 221, and a circulating fan 32 is installed on the second installation platform 222. A heater 33 is located below the lower bottom plate 23, above the lighting fixture installation and adhesive filling area 7.

[0027] like Figures 1-4As shown, the accelerated curing device for the pavement adhesive of the airport embedded lighting fixture base includes a cylinder 1, which is cylindrical with an opening 11 at the lower end, a closed upper part, and a hollow interior. The opening 11 at the lower end can completely cover the lamp installation and glue-filling area 7. To facilitate heating the internal space of the cylinder 1 and save energy, the cylinder 1 should not be too large. By covering the lamp installation and glue-filling area 7 with the cylinder 1, a closed space is formed to heat the lamp installation and glue-filling area 7 and accelerate the curing of the surface glue. An installation bracket 2 is provided inside the cylinder 1. The installation bracket 2 is I-shaped. Specifically, the top plate 21 is set on the top of the cylinder 1 by welding or bolting. The side of the vertical rod 22 is provided with a first installation platform 221 and a second installation platform 222 to provide installation points for the dehumidifier 31 and the circulating fan 32. The dehumidifier 31 is bolted to the first installation platform 221, and the circulating fan 32 is bolted to the second installation platform 222. The circulating fan 32 promotes airflow inside the cylinder 1, so that the cover formed by the cylinder 1 covers the lamp installation and glue-filling area. The air temperature in the enclosed space above area 7 is more uniform. A dehumidifier 31 controls the humidity within this space; when the humidity exceeds the limit, the dehumidifier 31 activates to ensure suitable conditions for the curing of the pavement adhesive, thus accelerating the curing process. A heater 33, located above the lamp installation and adhesive application area 7, is bolted to the bottom of the lower base plate 23. This heater 33 heats the entire internal cavity of the cylinder 1, raising the temperature within the enclosed space formed by the internal cavity of the cylinder 1 and the lamp installation and adhesive application area 7. The outer shell of the cylinder 1 effectively isolates its inner wall from the external environment, facilitating temperature control of the heater 33. Once the set temperature is reached, the device maintains a constant temperature, allowing the pavement adhesive applied to the lamp base installation to cure quickly, maximizing its performance. Furthermore, the device is small, lightweight, modular, has a high protection level, is easy to operate, and the heater 33 is energy-efficient, allowing for single-person operation. This device enables the installation and emergency repair of recessed lighting fixtures in low-temperature, cold, rainy, and snowy conditions, shortening the curing time of the pavement adhesive used for fixture base installation. In particular, it solves the installation challenge of recessed lighting fixtures in temperatures below 10℃, achieving domestic substitution of lighting fixture mounting adhesive and reducing construction costs. Internally, the device uses a metal mounting bracket 2 to layer and install a dehumidifier 31, a circulating fan 32, and a heater 33. The dehumidifier and heater 33 are all made of industrial-grade components, offering superior high-temperature resistance and durability, stable and efficient temperature control and heating, and greater energy savings. All external power cables 42 for internal components are made of flame-retardant and high-temperature resistant materials and protected by flame-retardant and high-temperature resistant protective tubing. The mounting bracket 2 is connected to the grounding terminal in the control box via a yellow-green dual-color grounding wire, ensuring safer operation.

[0028] To achieve intelligent control of the start and stop of the heater 33, circulating fan 32, and dehumidifier 31, so as to maintain a constant temperature and maximum humidity inside the cylinder 1, and ensure that the lamp installation and adhesive application area 7 under the cylinder 1 is always at the optimal temperature and humidity for pavement adhesive curing, thus shortening the curing time of the pavement adhesive, such as... Figure 1 , Figure 4 As shown, the accelerated curing device for the pavement adhesive of the airport embedded lighting fixture base also includes a controller 4 and a temperature and humidity sensor 5. The controller 4 is located at the top of the cylinder 1. The dehumidifier 31, the circulating fan 32, and the heater 33 are electrically connected to the controller 4. The controller 4 is also electrically connected to the temperature and humidity sensor 5. The detection end of the temperature and humidity sensor 5 extends through the top of the cylinder 1 and into the cylinder 1. The temperature and humidity inside the cylinder 1 are monitored in real time by the temperature and humidity sensor 5 and fed back to the controller 4. The controller 4 controls the operation of the heater 33 and the dehumidifier 31 to ensure that the temperature and humidity inside the cylinder 1 are always kept within the range most suitable for the curing of the pavement adhesive, thereby shortening the curing time of the pavement adhesive.

[0029] Specifically, during operation, the controller 4 sets a constant temperature and humidity. The heater 33 heats the enclosed space formed by the cylinder 1 and the road surface surrounding the lamp installation and glue-filling area 7. The circulating fan 32 inside the cylinder 1 accelerates internal air circulation. The temperature and humidity sensor 5 collects temperature and humidity data within the enclosed space and feeds it back to the controller 4. The controller 4 adjusts the heating intensity of the heater 33 and the dehumidification intensity of the dehumidifier 31 in real time to ensure that the environmental parameters within the enclosed space accurately match the curing requirements. The controller 4 also has a timer function, which can preset the working time based on test data to achieve automatic shutdown, further improving construction convenience and safety, and achieving energy saving. The device can be powered by 220V AC, suitable for various construction sites, and a small generator can meet the power requirements. The device shell is made of high-strength materials, is lightweight and impact-resistant, and adapts to complex environments. Multiple built-in safety protections ensure safe operation. The device adopts a modular design, facilitating maintenance and component replacement. It is lightweight and easy to operate, requiring only one person to operate.

[0030] To protect controller 4 from being rendered unusable due to rainfall, such as Figure 1 , Figure 4As shown, the controller 4 is covered by a housing 41, which has an inlet 411 and an outlet 412 for the power cord to pass through. The housing 41 provides waterproofing and dustproofing, preventing external environmental factors from affecting the normal operation of the controller 4. To facilitate the connection of the power cord and various electrical components inside the housing 1 with the controller 4, the housing 41 has an outlet 412 and an inlet 411 for the power cord to pass through. The housing 41 is an environmentally friendly housing with an IP66 protection rating, providing waterproofing and dustproofing. Waterproof locking nuts are installed at the outlet 412 and inlet 411. The housing 41 can also have an operation panel for operating the controller 4. The controller 4 is a micro-controller, offering stable performance, precise control, and a smaller footprint. A remote control module can be optionally installed for enhanced intelligence. The controller 4 uses a pre-installed external three-prong power cord, providing better safety protection and eliminating the need for a professional electrician to connect the wiring during operation.

[0031] To achieve rapid heating and constant temperature, such as Figure 1 , Figure 4 As shown, the side wall 12 of the cylinder 1 includes an inner side wall 121 and an outer side wall 122 made of stainless steel, and an insulation layer 123 is provided between the inner side wall 121 and the outer side wall 122. The side wall 12 of the cylinder 1 adopts a double-layer structure composed of the inner side wall 121 and the outer side wall 122, and both the inner side wall 121 and the outer side wall 122 are made of stainless steel, which meets the strength requirements while being low in cost and light in weight. An insulation layer 123 is provided between the inner side wall 121 and the outer side wall 122. The insulation layer 123 is filled with insulation materials such as rock wool, slag wool products, glass wool felt, or flame-retardant polyurethane foam. The material is lightweight and has good insulation effect, making it easy for operators to move and install.

[0032] To ensure the accelerated curing device for the pavement adhesive of the airport recessed lighting fixture base forms a sealed space with the pavement during use, thus guaranteeing the heating effect on the adhesive-filling area of ​​the lighting fixture located beneath the cylinder 1, such as... Figure 1 , Figure 4 As shown, the outer edge of the opening 11 is provided with a sealing ring 13 for sealing the junction of the cylinder 1 and the ground. The sealing ring 13 is arranged circumferentially around the opening 11 at the lower end of the cylinder 1. The sealing ring 13 is installed on the outer edge of the opening 11 at the lower end of the cylinder 1. As a preferred embodiment, the sealing ring 13 is a silicone sealing ring 13. The silicone sealing ring 13 has a good sealing effect and is resistant to high temperature. It can be used in the heating process of the accelerated curing device of the pavement adhesive for the embedded lighting base of the airport without being damaged.

The wear-resistant and anti-slip layer 15 is formed by applying a wear-resistant and anti-slip coating to the outer wall of the cylinder 1. Specifically, the wear-resistant and anti-slip coating can be a solvent-free polyurethane anti-slip coating, an epoxy anti-slip coating, or various powder anti-slip coatings.

[0034] To facilitate the relocation of the accelerated curing device for the pavement adhesive of the airport's embedded lighting fixtures, such as... Figure 1 , Figure 4 As shown, the cylinder 1 is provided with handles 14, and two handles 14 are symmetrically arranged on both sides of the cylinder 1; the handles 14 are also covered with anti-slip sleeves to increase the friction between the handles 14 and the operator.

[0035] Taking the installation of a commonly used 8-inch recessed light fixture as an example, the diameter of the hole drilled in the pavement is approximately 245mm, which means the maximum diameter of the glue-filled area is 245mm. A specific embodiment of the device is provided.

The cylinder wall of 1 is constructed with a double-layer stainless steel structure, with a wall thickness of 0.1mm. Rock wool insulation material, 1.5cm thick, is filled between the two thin stainless steel walls as an insulation layer 123. Two non-slip handles 14 are provided on the outer wall of the cylinder 1 for easy movement.

[0037] like Figure 1 , Figure 3 As shown, the housing 41 covering the controller 4 is an IP66 waterproof and dustproof housing. The housing 41 is made of environmentally friendly ABS material, and the viewing window is made of aging-resistant PC material. Waterproof locking nuts are installed at the cable outlet 412 and cable inlet 411 on the housing 41. The housing 41 is 178mm long, 176mm wide, and 100mm thick.
