Description

Technical Field

[0001] This utility model relates to the field of high-speed train maintenance, specifically to a device for controlling the curing environment of high-speed train side window glass. Background Technology

[0002] In the operation and maintenance of high-speed trains, replacing side window glass is a common and important task. The curing effect of glass sealant is closely related to the ambient temperature and humidity, and it needs to be kept within a specific temperature and humidity range to ensure curing quality. However, in reality, ambient temperature and humidity are difficult to control, especially in winter when the temperature is low and the air is dry. This directly leads to an increase in the drying time of the sealant after the side window glass is replaced, and at the same time, it makes it impossible to guarantee the curing quality.

[0003] Traditional maintenance work lacks effective auxiliary equipment specifically for the curing process of side window glass, making it difficult to maintain a curing environment under changing external conditions. This instability in the curing environment caused by environmental changes has become a key issue restricting the quality and efficiency of side window glass replacement. Patent CN222842470U provides a temperature control device for replacing side window glass in high-speed trains; however, while this device can regulate the ambient temperature after side window glass replacement, it cannot simultaneously and effectively control the ambient humidity.

[0004] Therefore, developing a control device that can simultaneously regulate temperature and humidity and provide a suitable drying environment for adhesive after the replacement of side window glass, in order to overcome the instability of the curing environment caused by changes in the external environment, has become an urgent need to solve the current technical bottleneck, thereby ensuring that maintenance quality and production efficiency are not excessively affected by seasonal factors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A curing environment control device for side window glass of a high-speed train includes a folding cover, a folding cover support arranged on the outside of the folding cover, the folding cover support including a fixed rod and several support rods, the fixed rod is installed at the geometric center of the folding cover, one end of the support rod is connected to the fixed rod, the other end is connected to the folding cover, and the support rod is telescopic.

[0008] A heating layer is arranged inside the folding cover, and a humidifier is connected to the inside of the folding cover.

[0009] The heating layer includes flame-retardant tubes arranged on the folded cover, and heating wires are installed inside the flame-retardant tubes.

[0010] The folding cover is divided into several folding units according to its folding state. Flame-retardant tubes are evenly distributed in each folding unit, and no flame-retardant tubes are installed at the connection between adjacent folding units.

[0011] The end of the fixing rod away from the support rod passes through the folding cover and is connected to a fixing suction cup, which is used to connect the folding cover and the side window glass during operation.

[0012] The strut is equipped with a locking device to fix the extension and retraction length of the strut.

[0013] An insulation layer is provided between the inside of the folded cover and the heating layer.

[0014] The folding cover has the same shape as the side window glass of the EMU, and its size is enlarged proportionally to that of the side window glass.

[0015] The heating layer is connected to a temperature control device, which is also connected to a temperature sensor, which is located inside the folded cover.

[0016] The humidifier is connected to a humidity control device, which is connected to a humidity sensor, which is located inside the folding cover.

[0017] Both the temperature control device and the humidity control device are single-chip microcomputers.

[0018] It also includes a leakage current protection device to cut off the power supply to the temperature and humidity control devices in the event of a leakage risk.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] This utility model provides a curing environment control device for side window glass of high-speed trains. A folding cover forms a localized coverage space for the side window glass, reducing the direct impact of the external environment on the glass area. The folding cover bracket controls its unfolding and folding states, ensuring the stable formation of this localized coverage space and further enhancing the barrier effect against external interference. The heating layer inside the folding cover, in conjunction with a temperature control device and a temperature sensor, can regulate the temperature within the covered area, avoiding the influence of external temperature fluctuations. A humidifier, working in conjunction with a humidity control device and a humidity sensor, can regulate the humidity within the covered area, resisting interference from changes in external humidity. The coordinated action of all components enables the device to maintain a stable curing environment for the glass, ensuring the curing quality after the side window glass is replaced.

[0024] After the replacement of the side window glass in high-speed trains, the curing quality of the sealant used to fix the glass is highly dependent on a stable temperature and humidity environment. However, in actual operation, the ambient temperature and humidity are uncontrollable, especially under the low temperature and dry conditions of winter. This not only significantly prolongs the curing time but also directly leads to a failure to guarantee the curing quality. Traditional maintenance operations lack specialized auxiliary equipment for the curing process, making it difficult to maintain stable curing conditions when the external environment fluctuates. Patent CN222842470U proposes a temperature control device for replacing the side window glass of high-speed trains, but it can only regulate the temperature and cannot simultaneously control the humidity, thus failing to solve the problem of coordinated temperature and humidity control.

[0025] Therefore, developing a side window glass curing environment control device that can simultaneously regulate temperature and humidity to overcome existing technological limitations and ensure that maintenance quality and production efficiency are not affected by seasonal factors has become an urgent technical need.

[0026] Based on the above background, this utility model proposes a curing environment control device for side window glass of high-speed trains. A folding cover provides targeted coverage of the side window glass, reducing interference from the external environment, while a support structure ensures stable coverage. A heating layer, temperature sensor, and control device work together to control temperature, while a humidifier, humidity sensor, and corresponding control device work together to control humidity, achieving precise and stable temperature and humidity in the curing environment around the glass, thereby overcoming the instability of the curing environment caused by external changes.

[0031] Reference Figure 1 As shown, this is a specific embodiment of the EMU side window glass curing environment control device provided by the present invention, which includes a folding cover 1, a folding cover support 2 arranged on the outside of the folding cover 1, the folding cover support 2 includes a fixed rod 201 and a plurality of support rods 202, the fixed rod 201 is installed at the geometric center of the folding cover 1, one end of the support rod 202 is connected to the fixed rod 201, and the other end is connected to the folding cover 1, the support rod 202 is telescopic;

[0032] A heating layer 3 is arranged inside the folding cover 1, and a humidifier 4 is connected to the inside of the folding cover 1.

[0033] The function of the folding cover 1 is to provide targeted coverage for the side window glass, thereby reducing interference from the external environment. The folding cover bracket 2 is installed on the outside of the folding cover 1 and is used to change the state of the folding cover 1. When the device is needed, the folding cover 1 is unfolded and fixed by the folding cover bracket 2, so that it stably covers the side window glass; when the device is not in use, the folding cover 1 is folded up by the folding cover bracket 2 for easy storage and transportation.

[0034] The folding cover bracket 2 consists of a fixed rod 201 and several support rods 202. The fixed rod 201 is installed at the geometric center of the folding cover 1, serving as the core support point of the entire bracket. One end of each support rod 202 is connected to the fixed rod 201, and the other end is directly connected to the folding cover 1. This radial connection method can evenly distribute the force, ensuring the stability of the folding cover 1 when unfolded. The support rods 202 adopt a telescopic design, and the unfolding range of the folding cover 1 can be flexibly controlled by adjusting its length, allowing the folding cover 1 to cover the side window glass when in use and to retract to reduce storage space when not in use.

[0035] The heating layer 3 arranged inside the folding cover 1 can directly release heat to the surrounding area of ​​the glass, providing the required temperature for the curing of the structural adhesive; at the same time, the connected humidifier 4 is responsible for regulating the humidity of the area. The two work together to create a suitable local environment for the curing of the side window glass.

[0036] In another specific embodiment of the high-speed train side window glass curing environment control device provided by this utility model, the heating layer 3 includes a flame-retardant tube arranged on the folding cover 1, with a heating wire installed inside the flame-retardant tube, and the heating wire connected to the temperature control device. The flame-retardant tube provides protection for the heating wire, preventing the heating wire from directly contacting other components and causing safety hazards. The heating wire, as the core of the heat generation, is an advanced heating element integrated inside the tooling, capable of uniformly dissipating heat and generating heat under the control of the temperature control device, thus accurately maintaining the internal ambient temperature between 15-30℃, effectively promoting adhesive curing. The temperature control device is a microcontroller, which has precise control capabilities and flexible programming characteristics, accurately receiving data from the temperature sensor and precisely controlling the heating layer 3 according to the preset program. At the same time, the tooling is equipped with an over-temperature protection mechanism, which automatically stops heating when the temperature exceeds the set upper limit, preventing damage to the side window glass and surrounding components due to excessive temperature.

[0037] The folding cover 1 is divided into several folding units 101 according to its folded state. Flame-retardant tubes are evenly distributed inside each folding unit 101, and no flame-retardant tubes are placed at the connection points of adjacent folding units 101. This design ensures uniform heating when the folding cover 1 is unfolded, and the presence of flame-retardant tubes does not affect the flexible folding of the folding units 101, ensuring the convenience of use and storage of the device. The size and shape of the folding cover 1 are precisely customized according to the contour of the EMU side window glass, and are the same shape as the EMU side window glass. The size is also proportionally enlarged to the side window glass, so that it can tightly cover the outside of the side window glass, forming a relatively stable local environment for the glass and surrounding area. This design allows the folding cover 1 to better fit the side window glass, ensuring complete coverage of the glass and surrounding adhesive layer, and preventing incomplete coverage due to size mismatch, providing a good foundation for the curing environment.

[0038] The end of the fixing rod 201 furthest from the support rod 202 passes through the folding cover 1 and is connected to a fixing suction cup 5, used to connect the folding cover 1 to the side window glass during operation. The fixing suction cup 5 uses atmospheric pressure to firmly adhere the folding cover 1 to the side window glass, enhancing the sealing and stability between the folding cover 1 and the glass, and preventing accidental movement during use from affecting the curing environment. The support rod 202 adopts a telescopic structure and is equipped with a locking device to fix the telescopic length of the support rod 202. The telescopic design allows the support rod 202 to adapt to the support needs of folding covers 1 of different sizes, while the locking device can fix the support rod 202 after it is adjusted to a suitable length, ensuring the stability of the support effect. When in use, loosen the locking mechanism to extend the support rod 202, and the folding cover 1 will unfold accordingly. Then tighten the locking mechanism to keep the folding cover 1 in the unfolded state. When not in use, loosen the locking mechanism to shorten the support rod 202. The support rods 202 connected to the four corners of the folding cover 1 will pull the four corners back to one side, and the folding cover 1 will fold up to reduce storage space.

[0039] A heat insulation layer is fixed inside the folding cover 1. In this specific embodiment, the heat insulation layer is made of aluminum foil. One side of the heat insulation layer is bonded to the folding cover 1 to form a composite structure that combines support and heat insulation performance, while the other side is provided with a heating layer 3. The aluminum foil material can reduce the heat loss from inside the folding cover 1 by reflecting heat. This composite structure can significantly improve the heat insulation effect, which not only improves the heating efficiency, but also effectively avoids the excessive influence of low external temperature on the internal temperature, thus helping to maintain a stable temperature environment.

[0040] The heating layer 3, located inside the folded cover 1, is a key component for providing heat, raising the temperature inside the folded cover 1 through heating. A temperature sensor, also located inside the folded cover 1, can detect internal temperature changes in real time and transmit the temperature data to a connected temperature control device. Upon receiving the data, the temperature control device adjusts the operation of the heating layer 3 according to a preset suitable curing temperature standard, ensuring that the temperature inside the folded cover 1 remains within a suitable range.

[0041] The inside of the folding cover 1 is connected to the humidifier 4 via a pipe. This pipe provides a path for the water vapor generated by the humidifier 4 to enter the interior of the folding cover 1, and the humidifier 4 is responsible for increasing the humidity inside the folding cover 1. A humidity sensor is installed inside the folding cover 1 to monitor the internal humidity in real time and send the monitored humidity information to a humidity control device. Based on this information, the humidity control device adjusts the operation of the humidifier 4 to maintain the humidity inside the folding cover 1 at a level conducive to the curing of the silicone sealant.

[0042] It should be noted that the temperature control device and humidity control device in this application can both be implemented by hardware, such as a microcontroller. The threshold for control is set in the microcontroller, and the sensor only performs a simple numerical comparison after collecting data. These are all conventional technical means. The heating layer 3 and the humidifier 4 are controlled according to the comparison results.

[0043] A humidifier 4 is connected to the inside of the folding cover 1 via a pipe. The humidifier 4 is connected to a humidity control device, which is a microcontroller connected to a humidity sensor located inside the folding cover 1. This humidity control device is a precision humidity control device that receives real-time humidity data from the humidity sensor, compares it to a preset suitable curing humidity range of 30%-70%, and controls the operation of the humidifier 4 to ensure the humidity of the adhesive curing environment remains between 30% and 70%. The humidifier 4 increases the humidity inside the folding cover 1, while the pipe provides a channel for moisture transmission. The humidity sensor continuously monitors the humidity inside the folding cover 1 and sends the data to the humidity control device.

[0044] In terms of the electrical system, the tooling is connected to a standard 220V socket in the warehouse to obtain power, and has a built-in reliable leakage protection device. This device is connected to the main circuit and will automatically cut off the power supply immediately once a leakage risk is detected, so as to ensure the safety of the operators.

[0045] This device is easy to install and operates stably. The combined use of the heating device with insulation materials, humidity control device 7, and humidifier significantly improves the efficiency and reliability of side window glass replacement operations. It effectively solves the problem of adhesive drying caused by poor environmental conditions in winter, providing strong support for the safe operation of high-speed trains. In use, the device is placed over the replaced side window glass, secured, and the heating device is turned on to maintain the temperature within the range of 15-30℃. The humidity control device ensures that the curing humidity is between 30% and 70%.

[0046] This solution utilizes an aluminum foil insulation layer on the inside of the folding cover 1 to form a composite structure, offering multiple beneficial effects. The aluminum foil reflects heat, significantly reducing heat loss from the folding cover 1, improving the heating efficiency of the heating layer 3, and reducing energy consumption. Simultaneously, this composite structure effectively blocks the influence of low external temperatures on the internal environment, enhancing temperature stability and providing consistently suitable temperature conditions for the curing of the side window sealant.

[0047] The rational arrangement of the insulation layer and heating layer 3 further ensures the efficiency of heat utilization, avoids temperature fluctuations from interfering with the curing process, helps to improve the curing quality after the replacement of the side window glass, reduces rework caused by unstable environment, indirectly improves work efficiency, and provides support for the reliable installation of the side window glass of the EMU.
