[0002] Mine transportation refers to the underground transportation work in the mine. The main task is to transport coal, followed by transporting waste rock out of the ground, transporting materials and equipment to the underground use site, and transporting personnel to and from work. During the transportation operation in the coal mine, it is necessary to monitor the safety status underground at all times and set up safety alarm devices to alarm any existing dangers so that personnel can evacuate quickly.

[0003] Although there are many kinds of safety alarm devices currently available, there are still some problems. For example, most of the current safety alarm devices are installed on the top of the mine tunnel under the mine. In order to ensure the operating status of the safety alarm device and avoid damage to it that makes it impossible to alarm for dangerous situations, maintenance personnel are required to inspect or repair the device regularly. During maintenance, maintenance personnel are required to remove the device installed on the top of the mine tunnel, and then install it back in place after the maintenance is completed. However, most of the current safety alarm devices are fixed with screws and other components. Therefore, a lot of time and energy are required when disassembling and assembling. In addition, due to the poor lighting conditions in the mine tunnel, it is even more inconvenient for maintenance personnel to disassemble and assemble the safety alarm device, which seriously affects work efficiency.

[0025] The present invention provides a coal mine electromechanical transportation safety alarm device, such as Figure 1-5 As shown, it includes: a support plate 1, a fixing seat 2, a safety alarm device body 3, a clamping ring 4, a limiting mechanism 5 and a locking mechanism 6;

[0026] The support plate 1 is connected to the bottom of the fixing base 2, the fixing base 2 is fixed to the top of the mine tunnel, the clamping ring 4 is fixed to the top of the safety alarm device body 3, and the clamping ring 4 is clamped on the limiting mechanism 5, which is set on the support plate 1;

[0027] The limiting mechanism 5 includes a docking plate 51, a hanging plate 52, a linkage rod 53 and a limiting rod 54. One end of the docking plate 51 is rotatably connected to the support plate 1, and two docking plates 51 are provided and symmetrically connected on both sides of the support plate 1. The top of the hanging plate 52 is rotatably connected between the two adjacent docking plates 51, and the snap ring 4 is clamped at the bottom of the hanging plate 52. One end of the linkage rod 53 is rotatably connected to the support plate 1, and the limiting rod 54 is rotatably connected between the two adjacent docking plates 51 away from one end of the hanging plate 52, and the other end of the linkage rod 53 is rotatably connected to the limiting rod 54. An abutting protrusion 55 is fixed on the side of the support plate 1 close to the hanging plate 52, and the abutting protrusion 55 abuts against the hanging plate 52, and the locking mechanism 6 is partially connected to the abutting protrusion 55

[0028] The locking mechanism 6 is connected to the docking plate 51 and includes a positioning hole 61, a locking cylinder 62, and a positioning rod 63. The positioning hole 61 is provided on the abutting protrusion 55. The locking cylinder 62 is fixed to the side wall of the docking plate 51. The positioning rod 63 is slidably connected to the axis of the locking cylinder 62, passes through the locking cylinder 62 and the docking plate 51, and is partially engaged in the positioning hole 61.

[0029] The locking mechanism 6 also includes a locking disk 64, a locking groove 65 and a locking protrusion 66. The locking disk 64 is coaxially fixed on the end of the positioning rod 63 away from the positioning hole 61. The locking groove 65 is concavely arranged on the edge of the locking cylinder 62 close to the side of the locking disk 64. The locking protrusion 66 is fixed at the edge of the locking disk 64, and the locking protrusion 66 is slidably engaged in the locking groove 65.

[0030] It should be noted that, since the existing safety alarm device requires maintenance personnel to inspect or repair the device regularly, and during maintenance, the maintenance personnel need to remove the device installed on the top of the mine tunnel, and then install it back in place after the maintenance is completed. However, most of the current safety alarm devices are fixed with screws and other components, so it takes a lot of time and energy to disassemble and assemble them. In addition, due to the poor lighting conditions in the mine tunnel, it is even more inconvenient for maintenance personnel to disassemble and assemble the safety alarm device, which seriously affects work efficiency. In order to solve this problem, a limiting mechanism 5 and a locking mechanism 6 are set in this solution, and the hanging plate 52 in the limiting mechanism 5 is docked with the clamping ring 4, and the hanging plate is pulled by the gravity of the safety alarm device body 3 itself. 52 is linked, and the limiting rod 54 is driven to be linked synchronously through the hanging plate 52 and the linkage rod 53, so that the limiting rod 54 abuts against one side of the hanging plate 52 to form a limiting structure, preventing the snap ring 4 from falling off, thereby forming a hanging locking effect for the safety alarm device body 3. The structure locked by self-gravity enables the safety alarm device body 3 to be quickly disassembled and assembled, thereby greatly increasing work efficiency, and at the same time avoiding the need to disassemble and assemble the safety alarm device body 3 in a dim environment, saving time and effort, and through the setting of the locking mechanism 6, the positioning rod 63 can be locked in the positioning hole 61, thereby locking the docking plate 51, thereby forming a limiting locking effect on the limiting rod 54, avoiding the safety alarm device body 3 from falling and being damaged.

[0031] Specifically, in this embodiment, this scheme mainly includes a support plate 1, a fixing seat 2, a safety alarm device body 3, a snap ring 4, a limit mechanism 5 and a locking mechanism 6. When in use, the fixing seat 2 is first fixed to the top of the mine tunnel. Before the safety alarm device body 3 is installed, the hanging plate 52 and the limit rod 54 are in a separated state. During installation, the snap ring 4 is docked with the hanging plate 52. At this time, under the action of the gravity of the safety alarm device body 3, the hanging plate 52 drives the docking plate 51 to be linked, and at the same time drives the limit rod 54 to be linked through the linkage rod 53 until the limit rod 54 abuts against one side of the hanging plate 52, limiting and locking the snap ring 4. At this time, the abutting protrusion 55 abuts against one side of the hanging plate 52, and then the lock disk 64 is rotated to make the locking protrusion 66 dock in the locking groove 65. At this time, the positioning rod 63 docks in the positioning hole 61, thereby locking the docking plate 51 and making the limit rod 54 synchronously locked.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the limiting mechanism 5 further includes a first return spring 56 , one end of the first return spring 56 is rotatably connected to the support plate 1 , and the other end is rotatably connected to the hanging plate 52 .

[0033] In this embodiment, the hanging plate 52 can be quickly reset by the elastic force of the first reset spring 56 , and drive the limiting rod 54 to move in conjunction, so that the limiting rod 54 is separated from the hanging plate 52 .

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a second return spring 67 is sleeved on the positioning rod 63 , one end of the second return spring 67 is fixed in the locking cylinder 62 , and the other end is rotatably connected to the lock disk 64 .

[0035] In this embodiment, the positioning rod 63 can be quickly reset and docked in the positioning hole 61 by the elastic force of the second reset spring 67 .

[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a through hole is provided on the fixing seat 2, and an expansion screw 7 is provided in the through hole, and an expansion sleeve is provided on the outside of the expansion screw 7. The fixing seat 2 is connected and fixed to the top of the mine tunnel through the expansion screw 7.

[0037] In this embodiment, the expansion sleeve is squeezed and expanded by the expansion screw 7, thereby improving the firmness of the connection between the fixing seat 2 and the mine tunnel to prevent loosening and falling.
