Description

Technical Field

[0001] The utility model belongs to the field of coal mine fault warning, and specifically relates to an automatic fault warning device for a coal mine conveyor belt. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. According to different mining methods, it is generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, generally, the surface soil layer is directly stripped to mine coal, which is a surface coal mine. In the coal transportation work of coal mines, idlers are often used to convey coal.

[0003] In the Chinese utility model patent with the publication number CN212291699U, a long-life idler structure for coal mine conveying is disclosed, which includes a roller frame, an idler chuck, a flat idler and an inclined idler. The inclined idlers are respectively arranged on both sides of the flat idler, and a chuck is arranged on the idler frame. The idler frame fixes the flat idler and the inclined idlers on both sides thereof through the chuck. This utility model seals the idler cover and the pipe body through a first sealing ring, separating the shaft and the bearing from the external environment, which can effectively prevent external dust, water, etc. from entering the bearing and damaging the bearing, and thus there is no need to adopt a complex sealing structure inside.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: This idler structure is generally used with a conveyor belt when transporting coal, and several idlers are arranged at intervals. When the conveyor belt is used on the idlers, when the coal weight on it is too much, the conveyor belt may sink between two adjacent idlers. Due to the lack of a reminder device for the material transportation volume, there are certain transportation safety hazards when the material volume is not controlled.

[0005] Therefore, those skilled in the art have proposed an automatic fault warning device for a coal mine conveyor belt to solve the problems raised in the background art. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an automatic fault warning device for a coal mine conveyor belt to solve the problem that in the prior art, this idler structure is generally used with a conveyor belt when transporting coal, and several idlers are arranged at intervals. When the conveyor belt is used on the idlers, when the coal weight on it is too much, the conveyor belt may sink between two adjacent idlers. Due to the lack of a reminder device for the material transportation volume, there are certain transportation safety hazards when the material volume is not controlled.

[0007] An automatic fault warning device for a coal mine conveyor belt, comprising a mounting frame and a conveyor body installed on the mounting frame. The conveyor body includes a conveyor belt drivingly connected thereto. The mounting frame further includes a mounting plate fixedly connected to its interior and a baffle fixedly connected to its upper end. An alarm component for emitting an alarm is provided on the mounting plate, and a dust reduction component for reducing the dust amount is provided on the baffle.

[0008] The alarm component includes a card slot opened on the upper surface of the mounting plate, a magnet fixedly connected to the inner bottom surface of the card slot, an iron block magnetically attracted to the magnet, and a button alarm installed on the upper surface of the iron block.

[0009] Preferably, a plurality of the mounting plates are installed, and two button alarms are installed on each mounting plate.

[0010] Through the above technical solution, during use, by starting the conveyor body and placing coal mine materials on the conveyor belt, coal mine conveying work can be carried out. After long-term use, the conveyor belt may become loose. Therefore, when the conveyor belt is conveying materials, it may sink between two adjacent conveyor rollers on the conveyor body. When the sinking amplitude is too large, the materials will press the conveyor belt downward to contact the start button on the button alarm, thereby achieving the effect of turning on the button alarm. At this time, an alarm can be issued to warn the staff not to stack too heavy materials on the conveyor belt, playing a role in early warning and subsequent protection of the conveyor body.

[0011] Preferably, the dust reduction component includes a mounting column fixedly connected to the upper end of the baffle, a rectangular frame fixedly connected to the upper end of the mounting column, a chute opened on one side inside the rectangular frame, a through groove opened on the other side inside the rectangular frame, a rectangular plate slidably connected to the through groove, a mounting groove opened on the lower surface of the rectangular plate, a cylinder installed at one end of the rectangular plate, a mounting block installed at the output end of the cylinder, and an atomizing nozzle installed on the lower surface of the mounting block.

[0012] Preferably, the output end of the cylinder is slidably connected to the rectangular plate, and the mounting block is matched with the mounting groove.

[0013] Preferably, the mounting block is hollow and fixedly communicated with the atomizing nozzle, and one end of the mounting block is fixedly communicated with a hose.

[0014] Preferably, a limiting column is fixedly connected to the upper surface of the rectangular frame, a limiting groove is opened at the upper end of the limiting column, and the hose is located in the limiting groove.

[0015] Preferably, a servo motor is installed at one end of the rectangular frame, a threaded rod is installed at the output end of the servo motor, and the threaded rod is threadedly connected to the rectangular plate.

[0016] Preferably, the threaded rod is located within the sliding groove, and one end of the threaded rod is rotatably connected to one end of the sliding groove. The thickness of the rectangular plate matches the height of the sliding groove.

[0017] Through the above technical solution, during use, by connecting one end of the hose to the water source output end, water can be supplied into the mounting block through the hose, enabling the atomizing nozzle to spray water into the air above the conveyor belt. By starting the servo motor, the threaded rod can be driven to rotate. The rotation of the threaded rod can drive the rectangular plate on its surface to move back and forth within the sliding groove, thereby achieving the effect of adjusting the position of the atomizing nozzle. By starting the cylinder, the mounting block can be driven to move within the mounting groove, thereby achieving the effect of adjusting the position of the atomizing nozzle left and right, improving the spraying effect of the atomizing nozzle and enhancing the dust suppression effect.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] 1. With the present utility model, the coal mine materials can be conveyed by starting the conveyor body to place the materials on the conveyor belt. After long-term use, the conveyor belt may become loose. Therefore, when the conveyor belt is conveying materials, it may sink between two adjacent conveyor rollers on the conveyor body. When the sinking amplitude is too large, the materials will press the conveyor belt to move downward and contact the start button on the button alarm, thereby achieving the effect of activating the button alarm. At this time, an alarm can be issued to warn the staff not to stack too heavy materials on the conveyor belt, playing a role in early warning and subsequent protection of the conveyor body.

[0020] 2. With the present utility model, by connecting one end of the hose to the water source output end, water can be supplied into the mounting block through the hose, enabling the atomizing nozzle to spray water into the air above the conveyor belt. By starting the servo motor, the threaded rod can be driven to rotate. The rotation of the threaded rod can drive the rectangular plate on its surface to move back and forth within the sliding groove, thereby achieving the effect of adjusting the position of the atomizing nozzle. By starting the cylinder, the mounting block can be driven to move within the mounting groove, thereby achieving the effect of adjusting the position of the atomizing nozzle left and right, improving the spraying effect of the atomizing nozzle and enhancing the dust suppression effect.
