DETAILED DESCRIPTION

[0018] Please refer to Figures 1-4The utility model provides following technical scheme: including installation pole 1, visual inspection subassembly 2, installation supporting plate 21 and laser detection subassembly 22, the fixed connection of installation pole 1 between has installation frame 11, two fixed plates 12 are installed on installation frame 11, and the first installation hole 13 and the second installation hole 131 are respectively set up on two fixed plates 12, the first installation hole 13 is matched with visual inspection subassembly 2, the second installation hole 131 is matched with installation supporting plate 21, and the horizontal pole 3 is installed between fixed plate 12, and the vertical rod 33 of sliding connection has on horizontal pole 3, and the baffle 34 corresponding with the first installation hole 13 is installed between vertical rod 33, and the connecting plate 23 is connected between installation supporting plate 21 and visual inspection subassembly 2, and the center pole 4 is installed on connecting plate 23, and two inclined poles 41 are installed on the outer wall of center pole 4, and the arc rod 42 is installed on the top of center pole 4.

[0019] In the embodiment: the mounting rod 1 is the carrier of the bearing device, which can be mounted on the belt rack in use, so that it is located below the belt. At this time, the first mounting hole 13 and the second mounting hole 131 opened on the two fixed plates 12 can be used to install the visual detection assembly 2 and the mounting plate 21. The laser detection assembly 22 installed on the inner wall of the mounting plate 21 can correspond to the belt in the mounting plate 21, which can cooperate with the real-time detection of the visual detection assembly 2 to enable the device to detect the belt tearing in real time, and ensure the safe transportation of the belt to the coal mine. When the device detects the belt, the device needs to be below the belt. When the belt is running and the belt is broken, the coal transported by the belt is disconnected, which causes the coal and the belt conveyor to separate. At this time, the device is directly below the belt, which will be directly impacted by the falling coal. At this time, the connecting plate 23 installed between the visual detection assembly 2 and the mounting plate 21 can be used to install and fix the center rod 4, so that the arc-shaped rod 42 installed on the top of the center rod 4 can be supported at the bottom of the belt conveyor belt. At this time, the arc-shaped rod 42 can correspond to the upper belt, and after the belt is broken and the support of the coal is disconnected, the arc-shaped rod 42 is subjected to downward pressure. At this time, the visual detection assembly 2 and the mounting plate 21 can be displaced downward under the connection of the connecting plate 23 to shrink to the position below the fixed plate 12, so that the visual detection assembly 2 and the laser detection assembly 22 can be protected. When the center rod 4 moves downward, the inclined rod 41 fixedly connected to the outer wall of the center rod 4 moves downward. At this time, the inclined rod 41 can support one end of the baffle 34 fixedly connected between the vertical rods 33 slidably connected to the horizontal rod 3, so that the baffle 34 is subjected to the downward pressure of the inclined rod 41. When the center rod 4 moves downward, the baffle 34 can move to the position above the fixed plate 12, so that the baffle 34 can move to the position above the visual detection assembly 2 and the laser detection assembly 22, thereby protecting the visual detection assembly 2 and the laser detection assembly 22. Thus, the device can protect the belt tearing in real time and prevent it from being damaged by the impact of the falling coal.

At the same time, when the center rod 4 moves downward under pressure, it can move downward synchronously.

[0021] The visual detection assembly 2 and the mounting plate 21 are provided with a sliding rod 25 at the bottom, a spring 24 is sleeved outside the sliding rod 25, and the sliding rod 25 is in sliding connection with a limiting frame 26; the sliding rod 25 provided at the bottom of the visual detection assembly 2 and the mounting plate 21 is limited to slide on the limiting frame 26, so that the spring 24 can be sleeved outside the sliding rod 25 to support the visual detection assembly 2 and the mounting plate 21, and at the same time, the visual detection assembly 2 and the mounting plate 21 can be vertically moved up and down to ensure that the visual detection assembly 2 and the mounting plate 21 can correspond to the first mounting hole 13.

[0022] The fixing plate 12 is provided with a clearance hole 121 for the clearance of the connecting plate 23; the clearance hole 121 provided on the fixing plate 12 is used for the clearance of the connecting plate 23, so that when the visual detection assembly 2 and the mounting plate 21 are connected through the connecting plate 23, the connecting plate 23 is prevented from being limited by the fixing plate 12 when being pushed and displaced, so that the visual detection assembly 2, the mounting plate 21 and the connecting plate 23 can adjust their positions on the fixing plate 12.

[0023] The horizontal rod 3 is provided with a fixed block 31, the fixed blocks 31 are fixedly connected with a fixed rod 32, and the fixed rod 32 penetrates the vertical rod 33; the fixed block 31 provided on the horizontal rod 3 can be used for installing and fixing the fixed rod 32, so that the fixed rod 32 can penetrate the vertical rod 33, the vertical rod 33 can slide horizontally on the fixed rod 32, and the baffle 34 can be prevented from being separated from the horizontal rod 3 and can slide above the fixed plate 12.

[0024] The vertical rod 33 is fixedly connected with a butt joint rod 35 corresponding to the inclined rod 41 at the top end; the butt joint rod 35 fixedly connected with the vertical rod 33 at the top end can correspond to the inclined rod 41, so that when the inclined rod 41 is moved downward, the inclined rod 41 can push the butt joint rod 35 and the baffle 34 to displace, the baffle 34 is displaced to above the fixed plate 12, and the visual detection assembly 2 and the laser detection assembly 22 are protected.
