Description

Technical Field

[0001] This utility model relates to the field of high-speed train glass repair technology, and in particular to a quick-drying device for glass glue used in high-speed train repair. Background Technology

[0002] EMU (Electric Multiple Unit) is a form of railway vehicle technology application. It is a series of high-speed trains developed for high-speed railway networks. EMU trains adopt advanced technology and have advantages such as high speed, high safety, and comfortable ride. During winter operation, EMU trains may experience problems such as glass breakage due to impact with foreign objects or glass defects. Therefore, it is necessary to repair and replace parts such as passenger compartment side windows, driver's cab side windows, driver's cab front windows, and driver's cab headlight glass.

[0003] Currently, during the maintenance of high-speed train glass, the low winter temperatures in Guiyang, often only -3°C to 8°C, pose a challenge. The required temperature for applying sealant and curing the adhesive during glass replacement is +15°C to +32°C. This unmet environmental requirement extends the drying time of the adhesive from the original 48 hours to approximately 120 hours during winter glass replacement. Insufficient drying time can lead to glass detachment, severely impacting train operation, especially during the Spring Festival travel rush. This can result in no trains available or even service disruptions, significantly affecting railway revenue. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the drying time of the adhesive used for replacing glass in winter is too long during the maintenance of high-speed trains, which reduces the utilization rate of the high-speed trains and thus affects railway revenue. Therefore, a quick-drying device for glass adhesive used in high-speed train maintenance is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-drying device for glass glue used in EMU maintenance includes a box body with a lid hinged to the top, the box body and the lid being fixed together by a snap fastener, and a heating blanket folded and stored inside the box body. The lid is provided with a control component for adjusting the working temperature of the heating blanket. The heating blanket is provided with a fixing component, which is used to fix the heating blanket to the EMU body when the heating blanket is unfolded.

[0007] In order to control the working temperature of the heating blanket, preferably, the control components include a temperature controller, a temperature alarm, and a buzzer fixedly installed inside the cover. The buzzer is electrically connected to the temperature alarm, and the temperature controller and the temperature alarm are respectively electrically connected to the heating blanket.

[0008] To facilitate the fixing of the heating blanket to the train body, preferably, the fixing component includes suction cups, and the number of suction cups is one, which are fixedly installed at the corners of the heating blanket.

[0009] In order to secure the closed lid and body of the box, preferably, the buckle includes a male buckle and a female buckle, and when the box body and lid are closed, the female buckle engages with the male buckle.

[0010] To facilitate pressing and securing the folded heating blanket inside the box, preferably, a movable plate is slidably installed laterally inside the box, and the movable plate is connected to a pressure plate via an elastic element. The pressure plate is pressed against the surface of the heating blanket by the elastic force of the elastic element.

[0011] To provide elasticity to the pressure plate, the elastic element further includes a pull rod that is longitudinally slidably connected to the movable plate, the bottom end of the pull rod being fixedly connected to the pressure plate, and a spring being fixedly installed between the movable plate and the pressure plate.

[0012] Compared with the prior art, this utility model provides a quick-drying device for glass glue used in EMU maintenance, which has the following advantages:

[0013] 1. This quick-drying device for glass glue used in EMU maintenance, through the combined use of heating blankets and temperature controllers, can ensure a constant ambient temperature when replacing glass glue on EMUs in winter, and can meet the environmental requirements for applying sealant and curing the glue, greatly shortening the drying time for replacing glass in winter, improving the utilization rate of EMUs, and providing a guarantee for railway revenue.

[0014] 2. The glass glue quick-drying device for EMU maintenance uses suction cups to quickly attach heating blankets to the EMU body, thereby improving work efficiency. It also employs a temperature alarm and buzzer for secondary temperature protection. When the temperature controller malfunctions and cannot control the temperature, the buzzer will be triggered to alert the operators to take timely action.

[0015] 3. The quick-drying device for glass glue used in the maintenance of this EMU uses a combination of pressure plate, moving plate, pull rod and spring to press and fix the folded heating blanket inside the box, preventing the heating blanket from automatically unfolding due to its own material memory and the action of internal air. This ensures that the folded heating blanket and wires are neat and stable in the closed space of the box and lid, avoiding mess and tangling, and making it convenient for workers to carry, transport and unfold for the next use.

[0016] 4. The quick-drying glass glue device for EMU maintenance, through the design of the box body, box cover, male and female buckles, makes the device lighter and more portable, allowing operators to carry it with them, which greatly facilitates the maintenance of EMU glass.

[0017] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model solves the problem that the drying time of the glass during winter replacement is too long when maintaining EMU trains, which reduces the utilization rate of EMU trains and thus affects railway revenue.

[0025] Example:

[0026] Reference Figures 1-4This utility model provides a quick-drying device for glass glue used in high-speed train maintenance, including a box body 1 with a lid 2 hinged to the top. A handle is rotatably connected to the top of the lid 2 for easy handling of the lid 2 and box body 1. The box body 1 and lid 2 are fixed together by a snap fastener, which includes a male snap fastener 21 and a female snap fastener 22. When the box body 1 and lid 2 are closed, the female snap fastener 22 engages with the male snap fastener 21, securing the closed lid 2 and box body 1 for easy carrying. It also includes a heating blanket 3 folded and stored inside the box body 1. The heating blanket 3 can be a Nanjiren S11 model. The 3474 or BriskHeat / SRL series has a control component inside the cover 2 for adjusting the working temperature of the heating blanket 3. The heating blanket 3 is equipped with a fixing component, which includes suction cups 31. There are 4 to 8 suction cups 31, which are fixedly installed at the corners of the heating blanket 3. Here, the device is preferably 4, which are fixed at the four corners of the heating blanket 3. When the heating blanket 3 is unfolded and working, the fixing component is used to fix the heating blanket 3 to the body of the EMU and fit the outer frame of the EMU glass, covering the glued part of the glass to facilitate the drying of the glue.

[0027] Specifically, during use, the control components and heating blanket 3 work together to ensure that the ambient temperature is constant when replacing the glass adhesive on the EMU in winter, and to meet the environmental requirements for applying sealant and curing the adhesive. This greatly shortens the drying time for replacing the glass in winter, improves the utilization rate of the EMU, and provides a guarantee for railway revenue. Furthermore, the setting of the fixing components makes it easy to fix the heating blanket 3 to the EMU body, thereby improving work efficiency.

[0028] The control components include a temperature controller 4, a temperature alarm 5, and a buzzer 51, all fixedly installed inside the cover 2. The temperature controller 4 is a KSD-9700 or KSD-302, the temperature alarm 5 is a Honeywell Lyric T6Pro or Codybo KD-110, and the buzzer 51 is a CMI-1295IC or HTD17E48. The buzzer 51 is electrically connected to the temperature alarm 5, and the temperature controller 4 and the temperature alarm 5 are electrically connected to the heating blanket 3.

[0029] Specifically, during use, the temperature controller 4 is first set to a stop temperature of 33°C and a start temperature of 32°C, while the temperature alarm 5 is set to a lower limit temperature of 5°C and an upper limit temperature of 37°C. The temperature controller 4 can control the working temperature of the heating blanket 3, ensuring that the ambient temperature of the dry adhesive remains at the set temperature when replacing the glass of the high-speed train in winter, which facilitates the rapid curing of the glass adhesive. Furthermore, during use, if the temperature controller 4 fails due to a malfunction, causing the temperature of the heating blanket 3 to rise continuously to 37°C or above, the temperature alarm 5 will trigger the buzzer 51 to alert the operators.

[0030] A movable plate 7 is horizontally slidably installed inside the box body 1. Slide grooves are provided on both sides of the inner wall of the box body 1. Sliders are fixedly connected to both ends of the movable plate 7. The sliders are slidably connected in the slide grooves. The movable plate 7 is connected to a pressure plate 6 through an elastic element. The pressure plate 6 is pressed against the surface of the heating blanket 3 by the elastic force of the elastic element. The elastic element includes a pull rod 8 that is slidably connected to the movable plate 7 in the longitudinal direction. The bottom end of the pull rod 8 is fixedly connected to the pressure plate 6. A spring 9 is fixedly installed between the movable plate 7 and the pressure plate 6.

[0031] Specifically, when the heating blanket 3 is folded and stored in the box 1, first pull the lever 8 upward to move the pressure plate 6 upward and compress the spring 9. Then slide the moving plate 7 and the pressure plate 6 to the middle of the heating blanket 3. Then release the lever 8. Under the action of the spring 9, the pressure plate 6 presses against the top surface of the heating blanket 3. This makes it easy to press and fix the folded heating blanket 3 in the box 1, preventing the heating blanket 3 from automatically unfolding under its own material memory and internal air action. This ensures that the folded heating blanket 3 and the wire are neat and stable in the closed space of the box 1 and the lid 2, avoiding mess and tangling. This makes it convenient for workers to carry and transport it and unfold it for the next use.

[0032] Working Principle: During use, the heating blanket 3 is first removed from the box 1 and unfolded. Then, it is attached to the train body by suction cup 31 and adhered to the outer frame of the train glass, covering the area to be sealed. Then, the power strip is connected. At the same time, the temperature controller 4 is set to a stop temperature of 33℃ and a start temperature of 32℃, while the temperature alarm 5 is set to a lower limit of 5℃ and an upper limit of 37℃. The temperature generated by the heating blanket 3 ensures a constant ambient temperature when replacing the sealant on the train glass in winter. It also meets the environmental requirements for sealing and curing of the sealant, greatly shortening the drying time for replacing the sealant in winter, improving the utilization rate of the train, and providing a guarantee for railway revenue.

[0033] Furthermore, during use, if the temperature controller 4 fails due to a malfunction, causing the temperature of the heating blanket 3 to continuously rise to 37°C or above, the temperature alarm 5 will trigger the buzzer 51 to sound an alarm, thereby reminding the operator to take timely action.

[0034] In addition, after the device is used up, the heating blanket 3 can be removed from the vehicle body and folded and stored in the box 1. Then, pull the lever 8 upward to move the pressure plate 6 upward and compress the spring 9. Next, slide the moving plate 7 and the pressure plate 6 to the middle of the heating blanket 3. Then release the lever 8. Under the action of the spring 9, the pressure plate 6 presses against the top surface of the heating blanket 3. This makes it easy to press and fix the folded heating blanket 3 in the box 1, preventing the heating blanket 3 from automatically unfolding under its own material memory and internal air action. This ensures that the folded heating blanket 3 and the wire are neat and stable in the closed space of the box 1 and the lid 2, avoiding mess and tangling. This makes it convenient for workers to carry and transport it and unfold it for the next use.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
