[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a safety protection device for track maintenance, including a device body 1, a docking shell 2 fixedly connected to the side surface of the device body 1, and a protective mechanism 3 installed on the upper surface of the device body 1; The protective mechanism 3 includes a docking shaft 301, which is mounted on the docking shell 2. A protective plate 302 is fitted onto the outer ring surface of the docking shaft 301. A positioning insertion clip 303 is fixedly connected to one side of the protective plate 302. A protective crossbar 304 is fixedly connected to the upper surface of the protective plate 302. A protective sleeve shell 305 is fixedly connected to the navigation surface of the docking shell 2. A fixing block 313 is fixedly connected to the side surface of the protective sleeve shell 305. A nut 314 is fixedly connected to one side of the fixing block 313. An insertion opening 306 is opened on the inner ring surface of the protective sleeve shell 305. A first storage shell 309 is fixedly connected to the upper surface of the device body 1. A second storage shell 311 is fixedly connected to the upper surface of the device body 1.

[0020] Furthermore, a protective frame 307 is fixedly connected to one side of the protective sleeve shell 305, and the protective frame 307 and the fixing block 313 are structurally compatible. The protective frame 307 is made of high-strength steel and has good impact resistance.

[0021] Furthermore, a handle 308 is fixedly connected to one side of the protective sleeve housing 305, and the handle 308 is connected to the track slide rail locking support block 4 through the protective sleeve housing 305. The surface of the handle 308 is covered with an anti-slip rubber sleeve, and the inside has an ergonomic groove structure. When the operator loads or unloads the protective sleeve housing 305, he or she can easily apply force through the handle 308 to avoid hand slippage.

[0022] Furthermore, a first partition plate 310 is fixedly connected to one side of the first storage shell 309, and there are multiple first partition plates 310 that are parallel to each other. The multiple parallel first partition plates 310 divide the interior of the first storage shell 309 into multiple independent spaces of equal size, which can store different types of maintenance tools such as screwdrivers, wrenches, and thickness gauges, to avoid the tools from colliding and wearing each other or getting mixed up, which would make it difficult to retrieve them.

[0023] Furthermore, a track slide rail snap-fit ​​support block 4 is fixedly connected to the bottom surface of the docking shell 2, and the track slide rail snap-fit ​​support block 4 is symmetrically arranged with the vertical center line of the main body 1 as the axis of symmetry. The symmetrical track slide rail snap-fit ​​support block 4 adopts a groove structure that matches the track slide rail, which can form a tight snap-fit ​​with the track to prevent the device from shifting laterally due to vibration or external force during maintenance.

[0024] Furthermore, a threaded rod 315 is fixedly engaged on the inner ring surface of the nut 314, and the threaded rod 315 is connected to the nut 314 and the fixing block 313. The threaded rod 315 and the nut 314 are fitted with a precision thread. Rotating the threaded rod 315 can adjust the tightness of the protective sleeve shell 305, making the operation simple and quick.

[0025] Furthermore, the inner surface of the second storage shell 311 is fitted with a second partition plate 312, and there are multiple second partition plates 312. The spacing of the multiple second partition plates 312 can be flexibly adjusted according to the specifications of the maintenance materials, and can store small parts such as track bolts and gaskets.

[0026] Working principle: When a user needs to use a safety protection device for track maintenance, the operator aligns the track slide rail clamping support block 4 at the bottom of the docking shell 2, which is fixed on the side surface of the device body 1, with the track slide rail clamping support block 4. Since the track slide rail clamping support block 4 is symmetrically set with the vertical center line of the device body 1 as the axis of symmetry, it can be smoothly clamped on the track to achieve initial positioning. Then, the threaded rod 315 that is limited and clamped by the inner ring of the fixing block 313 on the side of the protective sleeve shell 305 is rotated. The protective sleeve shell 305 is locked on the track structure by the cooperation of the nut 314 and the fixing block 313, thus completing the overall fixation of the device. The docking shaft 301 is installed on the docking shell 2, and then the protective plate 302 is limited and sleeved on the outer ring surface of the docking shaft 301. The positioning plug-in clip 303 on one side of the protective plate 302 ensures that the protective plate 302 is vertical and stable. At this time, the protective crossbar 304 fixed on the upper surface of the protective plate 302 forms a horizontal protection. At the same time, the protective frame 307 fixed on one side of the protective sleeve shell 305 fits with the fixed block 313, and together they form a safety protection barrier that combines vertical and horizontal protection. Open the first storage shell 309 and the second storage shell 311 fixed on the upper surface of the main body 1. Use the multiple parallel first partition plates 310 in the first storage shell 309 to classify and place maintenance tools, small parts, etc. The second partition plates 312 with multiple limit clips in the second storage shell 311 separate maintenance materials of different specifications, ensuring that materials can be easily accessed during maintenance. Maintenance personnel carry out track maintenance work inside the protective barrier. The protective plate 302 and the protective crossbar 304 prevent personnel from accidentally approaching the dangerous area of ​​the track. The protective frame 307 further protects against tools falling or external interference. When materials need to be replenished during operation, they can be taken directly from the first storage shell 309 and the second storage shell 311 without interrupting the protective state. After maintenance is completed, first organize the tools and materials in the first storage shell 309 and the second storage shell 311 and close the storage shells; then hold the handle 308 on one side of the protective sleeve shell 305, turn the threaded rod 315 in the opposite direction to loosen the fixation, remove the protective plate 302 and the docking shaft 301, and finally detach the track slide rail clip support block 4 from the track slide rail to complete the disassembly, transfer and storage of the device.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
