[0024] Please see Figure 1-6This utility model provides an emergency alarm device suitable for the construction of underground engineering projects for intercity railways. It includes a housing 1, with an alarm body 2 slidably mounted in the middle of the housing 1. The alarm body 2 is an existing device capable of displaying information about malfunctions, accidents, or dangerous situations. Inside the housing 1 are two vertical plates 3, and two inserts 4 are fixedly mounted on one side of each vertical plate 3. Slots 5 for insertion and engagement with the inserts 4 are provided on both sides of the housing 1. A support assembly 8 is provided at the bottom of each vertical plate 3 to support and reset the vertical plate 3 and the inserts 4. An inclined plate 6 is fixedly mounted at the bottom of each vertical plate 3. A sliding inclined block 7 is provided, which moves vertically and, in conjunction with the sliding inclined plate 6, causes the two inclined plates 6 to move in opposite directions horizontally. This allows the tightly inserted plug 4 to separate from the slot 5, facilitating the quick disassembly and removal of the alarm body 2. This improves the efficiency of installation and disassembly, as it eliminates the need for personnel to carry special tools when disassembling the alarm body 2, effectively reducing the complexity and time cost of the operation. A moving component 9 is provided at the bottom of the inclined block 7, which facilitates the vertical movement of the inclined block 7.

[0025] The support assembly 8 includes a guide block 801, which is slidably disposed at the bottom of the vertical plate 3. Both ends of the guide block 801 are fixedly connected to the inner wall of the box 1. A first spring 802 is sleeved on the outside of the guide block 801. One end of the first spring 802 is fixedly connected to the inner wall of the box 1, and the other end is fixedly connected to one side of the vertical plate 3. The support assembly 8 also includes two support plates 803, which are symmetrically fixedly installed at the bottom of the inclined block 7. A guide rod 804 is slidably disposed inside the support plate 803, and the bottom end of the guide rod 804 is fixedly connected to the bottom end of the inner wall of the box 1. A limit cap 805 is fixedly disposed at the top end of the guide rod 804. Through the support assembly 8, the vertical plate 3 plays a limiting and guiding role during horizontal movement. The first spring 802 can support and reset the vertical plate 3 and the insert block 4. The guide rod 804 and the limit cap 805 can facilitate the limiting and guiding role of the movement of the inclined block 7.

[0026] The moving component 9 includes a pull rod 901, which is fixedly installed in the middle of the bottom end of the inclined block 7. A second spring 902 is sleeved on the outside of the pull rod 901. The bottom end of the pull rod 901 passes through the box body 1 and is fixedly provided with a handle 903. An anti-slip sleeve is sleeved on the outside of the handle 903. The top end of the second spring 902 is fixedly connected to the bottom end of the inclined block 7, and the bottom end of the second spring 902 is fixedly connected to the inner wall of the box body 1. The moving component 9 also includes two limiting plates 904, which are fixedly installed on the bottom of both sides of the inclined block 7. The moving component 9 is designed to facilitate the downward extension of the pull rod 901, thereby moving the inclined block 7 in the vertical direction. Combined with the sliding inclined plate 6, the two inclined plates 6 can move synchronously in opposite directions in the horizontal direction. The second spring 902 provides support and reset for the inclined block 7. The limiting plates 904 limit the movement of the inclined block 7.

[0027] A guide plate 10 is fixedly provided on one side of the alarm body 2, and a guide groove 11 that slides with the guide plate 10 is provided on one side of the box body 1. Handles 12 are fixedly provided on both sides of the top of the alarm body 2. The guide plate 10 and the guide groove 11 play a guiding role in the installation of the alarm body 2, and the handles 12 make it easy to disassemble and remove the alarm body 2.

[0028] Two mounting plates 13 are fixedly provided on both sides of the box body 1. The mounting plate 13 has a mounting hole 14 in the middle. The mounting plate 13 and the mounting hole 14 are provided to facilitate the use of relevant bolts to fix the box body 1 in a suitable working location.

[0029] In use, firstly, using relevant bolts or other fasteners and the mounting holes 14 on the mounting plate 13, install the box 1 to a suitable working location. Then, use the alarm body 2. When the alarm body 2 needs to be disassembled for maintenance, the operator only needs to pull the lever 903 to pull the lever 901 downwards. The movement of the lever 901 will move the inclined block 7 vertically. At this time, the second spring 902 is in a compressed state. When the inclined block 7 moves, it is combined with the inclined plates 6 sliding on both sides, so that the two inclined plates 6 can move synchronously in opposite directions. At this time, the two vertical plates 3 slide along the surface of the guide block 801. At this time, the first spring 802 is in a compressed state. The synchronous displacement of the two plug blocks 4 can then cause them to separate from the slot 5. Using the handle 12, the alarm body 2 can be easily disassembled, facilitating subsequent maintenance and improving disassembly efficiency. After disassembly, the pull handle 903 can be released. Under the action of the first spring 802 and the second spring 902, the inclined block 7 and the inclined plate 6 will rebound, causing the plug block 4 to automatically reset. Finally, the alarm body 2 after maintenance is slidably placed inside the box 1 again using the guide plate 10. Then, the above operation steps are repeated, and the pull handle 903 is pulled again to move the plug block 4. When the alarm body 2 is inserted into the box 1, the pull handle 903 is released, allowing the plug block 4 to be inserted into the slot 5 again, completing the installation and fixing of the alarm body 2.
