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.

[0022] like Figures 1 to 4As shown, the present invention provides a portable coal mine safety alarm device, including an alarm 1; Alarm 1 is installed on one side of the coal mine pipeline 13. Hooks 2 are provided on both sides of the back of alarm 1. The side of hook 2 away from alarm 1 is hung on the surface of coal mine pipeline 13. Supports 3 are movably connected to both sides of the back of alarm 1 through pins. The side of support 3 away from alarm 1 is in contact with the ground. An adjustment structure is provided at the bottom of alarm 1. The adjustment structure can control the support height of support 3 so that alarm 1 can be switched between the hanging and detached states.

[0023] refer to Figure 4 The adjustment structure includes a screw 4 movably connected to the bottom of the alarm 1 via a bearing. A rotating wheel 5 is fixedly connected to the bottom of the screw 4. A transmission plate 6 is threadedly connected to the surface of the screw 4. The transmission plate 6 is located on the front of the bracket 3. Slide rods 7 located inside the bracket 3 are fixedly connected to both sides of the surface of the transmission plate 6. The slide rods 7 and the bracket 3 are slidably connected.

[0024] As a technical optimization of this utility model, the adjustment structure composed of screw 4, rotating wheel 5, transmission plate 6 and slide bar 7 achieves the effect of converting rotational motion into linear motion by using simple screw transmission, thereby accurately controlling the opening and closing angle of bracket 3. It provides a labor-saving and reliable operation method and realizes stable control of the support state of alarm 1.

[0025] refer to Figure 4 The screw 4 is fitted with a support plate 8 located on top of the rotating wheel 5. Both sides of the support plate 8 pass through the transmission plate 6 and are fixedly connected to the bottom of the alarm 1. The transmission plate 6 and the support plate 8 are slidably connected.

[0026] As a technical optimization of this utility model, by sleeved a support plate 8 fixed to the alarm 1 on the surface of the screw 4 and slidably connecting the transmission plate 6 with the support plate 8, the movement trajectory of the transmission plate 6 is guided and limited, which enhances the stability of the adjustment mechanism during operation, prevents the transmission plate 6 from rotating with the screw 4, and ensures the effective transmission of force.

[0027] refer to Figure 4 A crossbeam 9 is fixedly connected to the bottom of the bracket 3, and casters 10 are fixedly connected to both sides of the bottom of the crossbeam 9. The casters 10 can support the alarm 1 using the bracket 3.

[0028] As a technical optimization of this utility model, by setting a crossbeam 9 with casters 10 at the bottom of the bracket 3, the alarm 1 can be easily moved when the bracket 3 is unfolded and supported, which solves the problem of difficult transportation of heavy alarm 1. The casters 10 realize the flexible movement of the device and further improve the convenience.

[0029] refer to Figure 2 A rubber sleeve 11 is fitted on the surface of the slide rod 7. The rubber sleeve 11 is located inside the bracket 3, and the outer surface of the rubber sleeve 11 is in contact with the inner wall of the bracket 3.

[0030] As a technical optimization of this utility model, by covering the surface of the slide rod 7 with a rubber sleeve 11 and making the rubber sleeve 11 contact the inner wall of the bracket 3, the friction between the slide rod 7 and the bracket 3 and the operating noise are reduced. This not only makes the opening and closing action of the bracket 3 smoother, but also reduces the wear of metal parts and extends the service life of the device.

[0031] refer to Figure 2 The surface of the hook 2 is hollowed out, and a bolt assembly 12 is provided on the back of the hook 2. The front end of the bolt assembly 12 passes through the hook 2 and extends into the interior of the alarm 1. The alarm 1 and the bolt assembly 12 are threaded together.

[0032] As a technical optimization of this utility model, by setting the surface of the hook 2 to be hollow and setting the bolt assembly 12, the weight of the hook 2 itself is effectively reduced while ensuring the connection strength between the hook 2 and the alarm 1. At the same time, it is convenient for users to adjust the height of the hook 2 to meet the usage needs of different environments.

[0033] The working principle and usage process of this utility model are as follows: Under normal monitoring conditions, the alarm 1 is suspended and fixed on the coal mine pipeline 13 via the hook 2 on its back and continuously monitors. When it is necessary to move the alarm 1, the operator can rotate the wheel 5 located at the bottom of the alarm 1, which drives the screw 4 to rotate, thereby causing the transmission plate 6 threaded to it to move downward. The transmission plate 6 pushes the bracket 3 to rotate around the pin shaft through the sliding rods 7 on both sides, so that the universal wheel 10 at the bottom of the bracket 3 contacts the ground and gradually supports the entire weight of the alarm 1, thereby smoothly lifting the alarm 1 from the pipeline and converting it into a movable and detachable state. At this time, the operator can easily push the device to the new target position. After reaching the target position, the wheel 5 is rotated in the opposite direction, the transmission plate 6 moves downward, and the bracket 3 is retracted. The universal wheel 10 leaves the ground, and the alarm 1 is resuspended and fixed on the pipeline via the hook 2 under the action of gravity, restoring a stable working state. The entire process controls the support height of the bracket 3 by adjusting the structure, realizing a quick and convenient switch between the hanging and moving states without any disassembly or installation operations, which greatly improves the efficiency of movement and installation.

[0034] In summary, this portable coal mine safety alarm device, through the alarm 1 with hook 2, the bracket 3 movably connected to the alarm 1, and the adjustment structure at the bottom, achieves the effect of quickly switching the working state of the alarm 1 without disassembling any parts, solving the problem of low efficiency caused by the cumbersome disassembly and reinstallation required when moving traditional alarm devices.
