[0002] In the daily maintenance of subway vehicle brake calipers, the maintenance of the brake caliper pull rope is crucial. Currently, due to the long-term operation of the pull rope under complex conditions, its surface is prone to aging. Surface aging not only affects the service life of the pull rope, but may also reduce the reliability of the braking system and endanger driving safety. Therefore, during maintenance, maintenance personnel usually re-cover the outer surface of the pull rope with heat shrink tubing and perform heat shrink treatment. This treatment method can effectively isolate external corrosion such as moisture and dust, repair aging damage, extend the service life of the pull rope, and ensure the stable operation of the pull rope and even the entire brake caliper system, laying a solid foundation for the safe and stable operation of the subway.

Specifically, heat shrink tubing is manually placed on the release rope, and then heat shrinking is performed using a hot air gun. This method is labor-intensive and the quality of heat shrinking varies depending on the skill level of the operators. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 6 Example 1: This utility model proposes a portable automatic heat shrinking device, including: an operation component 1 and a positioning component; the operation component 1 includes a grip handle 101 and a heating ring 102, the heating ring 102 is fixedly installed on the side of the grip handle 101, and the heating ring 102 is electrically connected to the control device inside the grip handle 101; the positioning component consists of a linkage mechanism 2 and an abutment mechanism 3. The linkage mechanism 2 includes a fixed seat 201 and a linkage seat 202. The fixed seat 201 is fixedly installed on the side of the grip handle 101, and the linkage seat 202 is inserted into the side of the fixed seat 201. The abutment mechanism 3 includes a positioning seat 301 and an abutment wheel 302. The positioning seat 301 is inserted into the interior of the fixed seat 201 along the radial direction of the fixed seat 201, and the abutment wheel 302 is rotatably connected to the side of the fixed seat 201.

[0023] The positioning components are arranged in two sets, symmetrically on both sides of the heating ring 102. The fixing base 201, the linkage base 202, and the heating ring 102 are arranged on the same axis. The fixing base 201 is provided with three sets of abutment mechanisms 3, which are arranged in a ring array on the fixing base 201. The included angle between adjacent abutment mechanisms 3 is 120 degrees. In use, the heating ring 102 can relieve the heat shrinking treatment of the new heat shrink tubing outside the pull rope by the brake clamp passing through it. It is easy to operate and flexible to use. The heating temperature of the heating ring 102 can be adjusted by the control device inside the grip handle 101, which can adapt to the heat shrinking treatment of heat shrink tubing of different specifications. The grip handle 101 is covered with rubber material, which increases the friction when gripping and makes it stable to use. The operating component 1 and the positioning component are compact, small and portable, and have great flexibility.

[0024] The positioning seat 301 has a positioning groove 3011 inside, and the linkage seat 202 has a positioning rod 2022 on its side. The positioning rod 2022 is inserted into the positioning groove 3011. In use, the positioning component can position the rope passing through it, so that the brake caliper releases the pull rope and the new heat shrink tubing is always in the center of the heating ring 102. This ensures that the heat shrink tubing is heated evenly around its perimeter during heat shrinking, resulting in high heat shrinking quality. The positioning component can automatically adapt to the outer diameter of the heat shrink tubing, realizing automatic positioning operation and simplifying the operation process. The heat shrink tubing can be directly passed through the linkage mechanism 2 and the heating ring 102. The side is provided with a positioning top spring 2021, and the two ends of the positioning top spring 2021 abut against the side of the linkage seat 202 and the side of the fixed seat 201 respectively. When the heat shrink tube passes through the inside of the linkage mechanism 2, the outer wall of the heat shrink tube will abut against and squeeze the abutment wheel 302, causing the positioning seat 301 to move outward. When the positioning seat 301 moves outward, the positioning groove 3011 can drive the linkage seat 202 to move towards the fixed seat 201 through the positioning rod 2022, thereby compressing the positioning top spring 2021, providing the abutment mechanism 3 with the abutment and positioning force against the outside of the heat shrink tube. The three sets of abutment mechanisms 3 can automatically position the heat shrink tube to the center position, which is convenient and flexible to use.

[0025] The working principle of this embodiment is as follows: The positioning component can position the cord passing through it, ensuring that the brake caliper releases the pull cord and the new heat shrink tubing are always at the center of the heating ring 102. This ensures uniform heating around the heat shrink tubing during heat shrinking, resulting in high heat shrinking quality. Furthermore, the positioning component can automatically adapt to the outer diameter of the heat shrink tubing, achieving automatic positioning. The heat shrink tubing can be directly passed through the linkage mechanism 2 and the heating ring 102. When the heat shrink tubing passes through the linkage mechanism 2, the outer wall of the heat shrink tubing will abut and press against the abutment wheel 302, causing the positioning seat 301 to move outward. As the positioning seat 301 moves outward, the positioning groove 3011 can drive the linkage seat 2 via the positioning rod 2022. 02 moves toward the fixed seat 201, thereby compressing the positioning top spring 2021, providing the abutment mechanism 3 with the abutment and positioning force against the outside of the heat shrink tube. The three sets of abutment mechanisms 3 can automatically position the heat shrink tube to the center position. The heating ring 102 can relieve the heat shrinking treatment of the new heat shrink tube outside the pull rope by the brake clamp passing through it. It is easy to operate and flexible to use. The heating temperature of the heating ring 102 can be adjusted by the control device inside the grip handle 101, which can adapt to the heat shrinking treatment of heat shrink tubes of different specifications. The grip handle 101 is covered with rubber material, which can increase the friction when gripping, making it stable to use. The operating component 1 and the positioning component have a compact structure.

[0026] In another embodiment, the distance between the fixed seat 201 and the linkage seat 202 can be adjusted by bolts. One end of the bolt is rotatably connected to the inside of the fixed seat 201, and the bolt is screwed into the inside of the linkage seat 202 through the rod thread. So when the bolt rotates, it can drive the linkage seat 202 to move and change the distance between it and the fixed seat 201. When the linkage seat 202 moves, the positioning rod 2022 can drive the positioning seat 301 to move through the positioning groove 3011, thereby changing the effective positioning outer diameter of the abutment mechanism 3. This can realize the function of manually adjusting the positioning outer diameter and positioning pressure of the heat shrink tubing.
