Description

Technical Field

[0001] This utility model relates to a collision avoidance alarm device for mining locomotives, belonging to the field of alarm technology. Background Technology

[0002] Materials, slag, equipment, and other equipment in coal mines are mostly transported by underground mining locomotives. Typically, many locomotives operate simultaneously in a single mine. As mine roadways extend, numerous junctions are created. Locomotives traveling at high speeds frequently collide at these junctions, causing injuries, material damage, and severely impacting safe production and daily life in the mine. The traditional solution is to install audible and visual alarm devices on the top of the roadway at junctions, issuing an alarm for a period before and after a locomotive has passed, and then deactivating it. However, this does not effectively solve the problem of collisions occurring at high speeds.

[0003] Therefore, this utility model proposes a new solution. Utility Model Content

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] like Figures 1-6 As shown, the anti-collision alarm device for mining locomotives provided in this embodiment includes a fixed frame 1, an anti-collision frame 2 installed on the front of the fixed frame 1, multiple buffer mechanisms installed between the fixed frame 1 and the anti-collision frame 2, two support columns 3 fixedly connected to the top of the anti-collision frame 2, a warning light 4 installed on the top of the support columns 3, a distance sensor 5 installed between the two support columns 3, and a buzzer 6 installed on the front of the support columns 3. It also includes a controller installed inside the mining locomotive, and the controller is electrically connected to the warning light 4, the distance sensor 5 and the buzzer 6. The fixed frame 1 and the anti-collision frame 2 are used to fix the fixed frame 1 on the mining locomotive. The fixed frame 1 and the anti-collision frame 2 are equipped with a buffer mechanism, which can absorb some of the kinetic energy in the event of a collision, reduce the damage, and ensure the safety of the locomotive and personnel. The warning light 4, the distance sensor 5 and the buzzer 6 are connected by the controller through electrical signals. When the distance sensor 5 detects that the locomotive is close, the controller controls the warning light 4 to flash to remind the driver and at the same time controls the buzzer to sound a warning, so as to prevent the driver from failing to see the light signal in time. It should be noted that the distance sensor 5 is a KJT-EXTLS-10C explosion-proof laser distance displacement sensor to ensure safety when used in the mine.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a mounting frame 7 is fixedly connected to the back of the mounting bracket 1. The mounting frame 7 has multiple connection holes 8. The mounting bracket 1 includes two parallel frames 101, with connecting posts 102 connecting the four corners of the two frames 101. The mounting frame 7 and the connection holes 8 allow for bolt connection to the locomotive, facilitating assembly and disassembly.

[0029] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the buffer mechanism includes a telescopic tube 103 fixedly connected to the front of the connecting column 102, a telescopic rod 201 fixedly connected to the back of the anti-collision frame 2 and slidably connected to the telescopic tube 103, a sliding rod 202 fixedly connected to one end of the telescopic rod 201, a sliding hole 104 slidably connected to the sliding rod 202 on the connecting column 102, a first spring 9 installed on the outer wall of the sliding rod 202, a damping block 10 sleeved on the outer wall of the sliding rod 202 at one end of the first spring 9, a limiting groove 105 opened on the side wall of the telescopic tube 103, a limiting block 203 slidably connected to the limiting groove 105 fixedly connected to the outer wall of the telescopic rod 201, and a buffer pad 11 installed on the front of the anti-collision frame 2. When a collision occurs, the object first hits the anti-collision frame 2. The anti-collision frame 2 slides relative to the fixed frame 1. The buffer pad 11, the first spring 9, and the damping block 10 play a buffering role. The limit groove 105 and the limit block 203 prevent the anti-collision frame 2 from separating from the fixed frame 1.

[0030] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the buffer mechanism also includes a fixing tube 106 installed on the front of the connecting column 102 located on the back of the fixed frame 1. A second spring 12 is installed on the inner side of the fixing tube 106, and a top plate 13 located on the inner side of the fixing tube 106 is installed on the front of the second spring 12. An intermediate rod 14 is connected between the two support columns 3, and a distance sensor 5 is installed in the middle of the intermediate rod 14. With the setting of the second spring 12 and the top plate 13, when the impact force is large, the anti-collision frame 2 slides relative to the fixed frame 1, compressing the first spring 9, and the sliding rod 202 extends from the sliding hole 104 and hits the top plate 13 to compress the second spring 12, which can further absorb kinetic energy; the distance sensor 5 is installed in the middle of the intermediate rod 14 to ensure the accuracy of distance measurement.

[0031] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the anti-collision alarm device for mining locomotives provided in this embodiment is as follows:

[0032] Step 1: When the distance sensor 5 detects that the locomotive is too close, the controller controls the warning light 4 to flash to remind the driver, and at the same time controls the buzzer to sound an alarm to prevent the driver from failing to see the light signal in time;

[0033] Step 2: When the locomotive cannot brake in time and collides, it first hits the anti-collision frame 2. The anti-collision frame 2 slides relative to the fixed frame 1, and the buffer pad 11, the first spring 9 and the damping block 10 play a buffering role.

[0034] Step 3: When the impact force is large, the anti-collision frame 2 slides relative to the fixed frame 1, compressing the first spring 9, and the slide rod 202 extends out from the slide hole 104 and hits the top plate 13 to compress the second spring 12, which can further absorb kinetic energy.

[0035] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
