Description

Technical Field

[0001] This utility model relates to the field of railway vehicle components, specifically to a compatible heat shrinkable snow cover device. Background Technology

[0002] In the field of high-speed railways and EMUs, steel springs, as the core elastic element of the vehicle suspension system, bear the important tasks of supporting the weight of the car body, absorbing the impact and vibration caused by track irregularities, maintaining vehicle stability, and ensuring good wheel-rail contact. These functions are crucial to ensuring the safety, comfort, and operational efficiency of EMUs. Because steel springs are directly exposed to the external environment, they are susceptible to the effects of harsh weather conditions, especially in cold regions where ice, snow, and low temperatures can cause a decline in spring performance or even damage. Therefore, installing snow covers on steel springs to protect them from the effects of ice, snow, and low temperatures is particularly important. Heat-shrink technology for snow covers is an effective method to ensure a tight fit between the snow cover and the steel spring, forming a sealed protective layer. By heating and shrinking the snow cover material, a tight fit between the snow cover and the steel spring can be ensured, providing durable protection.

[0003] While heat shrink technology plays a crucial role in the installation of snow covers, existing heat shrink equipment for steel spring snow covers has several significant limitations in practical applications. These devices typically only possess basic heat shrinking capabilities, lacking integration with modern high-speed train maintenance lines and failing to automate loading and unloading processes, resulting in low production efficiency. Furthermore, due to the lack of effective integration with other parts of the production line, these devices require additional manual intervention during operation, increasing labor intensity and production costs. The consistency and accuracy of manual operation are difficult to guarantee, potentially leading to improper installation or poor sealing of the snow covers, affecting their protective effect. These problems limit the efficiency and quality of heat shrink equipment for steel spring snow covers and urgently require improvement.

[0004] To address these issues, it is necessary to develop a new type of heat-shrinkable equipment for steel spring snow covers. This equipment can be seamlessly integrated with the steel spring maintenance production line to achieve automated feeding, improving operational efficiency and accuracy. This new equipment will significantly improve the automation level of the steel spring maintenance production line, reduce production costs, and simultaneously enhance operational safety and efficiency.

[0031] Reference Figure 1 The diagram illustrates a specific embodiment of a compatible snow cover heat shrinking device of this utility model. The device includes a heating device 1, a steel spring rotating device 2, and a steel spring slide 3. The heating device 1 is connected to the steel spring slide 3, and the steel spring rotating device 2 is arranged on the steel spring slide 3. The heating device 1 heats the snow cover on the steel spring, causing it to shrink and fit tightly against the steel spring. The steel spring rotating device 2 rotates the steel spring during the heating process to ensure that the snow cover is heated evenly. The steel spring slide 3 drives the steel spring to reciprocate between the heat shrinking position and the unloading position.

[0032] Reference Figure 4 As shown, the steel spring slide table 3 includes a traveling base 301, and a steel spring rotating device 2 is arranged on the traveling base 301. The traveling base 301 drives the steel spring rotating device 2 to reciprocate between the heat shrink position and the unloading position.

[0033] Reference Figure 2As shown, the heating device 1 includes a heating shell 102, inside which a heating tube 101 is arranged, and a shell opening and closing device 103 is connected to the bottom of the heating shell 102. The heating tube 101 provides heat, causing the snow cover material to shrink, the heating shell 102 protects the heating tube 101 and controls the heating area, and the shell opening and closing device 103 controls the opening and closing of the heating shell 102.

[0034] It should be noted that in this embodiment, there are two heating shells 102, which are arranged on both sides of the steel spring rotating device 2 and are respectively connected to the shell opening and closing device 103. The heating shells 102 close when the steel spring rotating device 2 reaches the heat-shrink position. At this time, the heating tube 101 is activated to heat the steel spring on the steel spring rotating device 2.

[0035] Reference Figure 3 As shown, the steel spring rotating device 2 includes a drive motor 204, which is connected to a drive wheel 203. The drive wheel 203 drives the placement rack 201 via a driven wheel 202. The placement rack 201 is arranged on the traveling base 301. The placement rack 201 is used to store steel springs. The driven wheel 202 cooperates with the drive wheel 203 to realize the rotation of the steel springs. The drive wheel 203 is driven by the drive motor 204, which drives the driven wheel 202 to rotate. The drive motor 204 provides power to drive the drive wheel 203.

[0036] The steel spring rotating device 2 can be installed as a whole on the walking base 301, or the drive motor 204 can be installed at the heat shrink position. When the walking base 301 moves to the heat shrink position, the drive wheel 203 contacts the driven wheel 202 to achieve transmission.

[0037] Reference Figure 4 As shown, the steel spring slide table 3 also includes a rodless cylinder 302, which is connected to the walking base 301 to provide power to the walking base 301 and drive the walking base 301 to move.

[0039] The heating device 1 and the steel spring slide 3 are arranged in a "T" shape.

[0040] Another specific embodiment of this utility model provides a specific application scenario for a compatible snow cover heat shrinking device. This embodiment employs a robot for loading, ensuring the robot system is calibrated and can accurately identify and grasp the steel spring. Simultaneously, the communication and control interface between the robot and the heat shrinking device is checked for proper function. The steel spring to be installed on the snow cover is placed in the designated storage location. The robot grasps the steel spring from this location and precisely places it on the placement rack 201 of the steel spring rotating device 2, ensuring correct placement and stable support from the placement rack 201. The heating shell 102 is closed via the shell opening and closing device 103, and the heating tube 101 begins heating. The drive motor 204 drives the driving wheel 203 and the driven wheel 202, causing the steel spring to rotate during heating, ensuring the snow cover is evenly heated and tightly adheres to the steel spring.

[0041] After heat shrinking, the heating shell 102 is opened via the shell opening and closing device 103, and the rodless cylinder 302 drives the walking base 301 to move the steel spring rotating device 2 to the unloading position. The steel spring is then manually removed from the placement rack 201 and placed in the designated unloading position. After use, the robot and heat shrinking device are cleaned and maintained. The components of the heating device, steel spring rotating device, and steel spring slide are inspected for damage or wear, and replaced or repaired if necessary.

[0042] Another feeding method of this invention is conveyor belt feeding, suitable for continuous steel spring supply on a production line. Ensure the conveyor belt is calibrated and can smoothly transport the steel springs. Simultaneously, check the accuracy of the connection between the conveyor belt and the heat shrinking device. Place the steel spring to be fitted with the snow cover on the conveyor belt, which will transport the spring to the feeding position of the heat shrinking device.

[0043] When the steel spring reaches the loading position, it is transferred from the conveyor belt to the placement frame 201 of the steel spring rotating device 2, ensuring correct placement and stable support from the placement frame 201. Subsequently, the heating shell 102 is closed via the shell opening and closing device 103, and the heating tube 101 begins heating. The drive motor 204 drives the driving wheel 203 and the driven wheel 202, causing the steel spring to rotate during heating, ensuring the snow cover is evenly heated and tightly adheres to the steel spring.

[0044] After heat shrinking, the heating shell 102 is opened via the shell opening and closing device 103, and the rodless cylinder 302 drives the traveling base 301 to move the steel spring rotating device 2 to the unloading position. The operator removes the steel spring from the placement rack 201 and places it in the designated unloading position. After use, the conveyor belt and heat shrinking device are cleaned and maintained, and the components of the heating device, steel spring rotating device, and steel spring slide are inspected for damage or wear. If necessary, they are replaced or repaired.
