Furthermore, the terms "first," "second," etc., are used only for descriptive distinction and should not be construed as indicating or implying relative importance. All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0023] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a conveyor belt anti-coal-stacking device, including a belt conveyor 1. The belt conveyor 1 is used for material transportation in the coal preparation industry. During long-term, high-load operation, coal blockage will occur, which will lead to equipment damage, production interruption, and even serious safety accidents, threatening the lives and property of personnel. The detection component 3 is set on the outside of the rotating shaft 202 to detect the coal blockage phenomenon on the working face of the belt conveyor 1. The disassembly component 2 is set on both sides of the frame of the belt conveyor 1 for disassembling and replacing the rotating shaft 202.

[0025] like Figure 1-6As shown in the embodiment of this application, the disassembly assembly 2 includes a fixed base 201, which is located on both sides of the frame of the belt conveyor 1. A rotating shaft 202 is provided on the inner wall of the fixed base 201, and a strip column 203 is provided between the rotating shafts 202. Specifically, the fixed base 201 is fixedly installed on both sides of the belt conveyor 1, and a through hole is provided through the fixed base 201. The diameter of the through hole is slightly larger than the diameter of the rotating shaft 202. During the rotation of the strip column 203, the rotating shaft 202 will be driven to rotate synchronously. That is, the rotating shaft 202 rotates on the inner wall of the fixed base 201. Due to the different diameter settings, the rotating shaft 202 can slide on the inner wall of the fixed base 201, which makes it easy to remove the rotating shaft 202 from the inner wall of the fixed base 201 and replace the rotating shaft 202.

[0026] like Figure 1-6 As shown in the embodiment of this application, a screw 205 is fixedly connected to one side of the rotating shaft 202 and is connected to the strip column 203 through the screw 205. A cross bar 204 is fixedly connected to one side of the other rotating shaft 202 and is connected to the strip column 203 through the cross bar 204. Specifically, when installing the rotating shaft 202, the center point of the strip column 203 is aligned with the center of the through hole on the fixing seat 201, and then the cross bar 204 on one side of one of the rotating shafts 202 is inserted into the strip column. The inner wall of column 203 has a cross groove, which is adapted to the cross rod 204. After the cross rod 204 enters the cross groove of column 203, the rotating shaft 202 and column 203 will be relatively fixed. After the cross rod 204 is inserted into one end of column 203, the other end of column 203 is installed by rotating the screw 205 on one side of the other rotating shaft 202 into column 203. The screw 205 and column 203 are threaded together. After being fully submerged within the strip column 203, the rotating shaft 202 and the strip column 203 will be relatively fixed. When the ends of the strip column 203 are connected to the rotating shaft 202, and the insert rod 206 is not installed, the strip column 203 will limit the rotation of the shaft 202. However, there is a certain distance between the strip column 203 and the fixed base 201. Therefore, although the strip column 203 can limit the rotation of the shaft 202 within the fixed base 201, the shaft 202 still has a certain displacement within the fixed base 201. The cooperation of the cross bar 204, screw 205 and strip column 203 facilitates the disassembly and replacement of the rotating shaft 202 and the strip column 203. It should be noted that the rotating shafts 202 inside the fixed seats 201 on both sides of the belt conveyor 1 frame can be configured to connect to either the cross bar 204 or the screw 205. Alternatively, one rotating shaft 202 can be connected to the cross bar 204 and the other rotating shaft 202 can be connected to the screw 205. These are two ways to connect to the strip column 203.

[0027] like Figure 1-6 As shown in the embodiment of this application, a plug 206 is provided on the outer wall of the rotating shaft 202. The plug 206 and the fixed rod 305 are located at the same center point. Specifically, a hole is provided on the outer wall of the rotating shaft 202, and the plug 206 is provided in the hole. The connection between the plug 206 and the hole on the rotating shaft 202 can be a threaded connection or a vertical connection. However, it should be noted that if it is a vertical connection, the outer wall of the plug 206 will contact the inner wall of the hole in the rotating shaft 202, and the plug 206 and the hole in the rotating shaft 202 will fit tightly. It requires an operator to use a... A certain amount of force is required to remove the insertion rod 206 from the rotating shaft 202. The outer wall of the top end of the insertion rod 206 contacts one side of the fixing seat 201. Under the action of the insertion rod 206, the rotating shaft 202 can be relatively limited within the fixing seat 201, thereby ensuring that the rotating shaft 202 will not slide inside the fixing seat 201 after the insertion rod 206 is installed. Removing the insertion rod 206 makes it easy to disassemble the rotating shaft 202. It should be noted that after the rotating shaft 202 is installed, the installation position of the insertion rod 206 will be perpendicular to the upper surface of the fixing seat 201.

[0028] like Figure 1-6 As shown, the detection component 3 includes an arc-shaped steel plate 304, which is located outside the rotating shaft 202 and connected to the outer wall of the rotating shaft 202 via a fixing rod 305. A switch sensor 302 is provided on one side of the arc-shaped steel plate 304, which is located on one side of the frame of the belt conveyor 1. Specifically, the switch sensor 302 of this application is connected to an external power supply and controlled by a control system. During the rotation of the rotating shaft 202, the arc-shaped steel plate 304 can be rotated via the fixing rod 305. The arc-shaped steel plate 304 is located in the gap between the upper frame and the conveyor belt of the belt conveyor 1. The fixing rod 305 is threadedly connected to the rotating shaft 202, but movably connected to the arc-shaped steel plate 304. The arc-shaped steel plate 304 is tightly installed on the outer wall of the fixing rod 305. The arc-shaped steel plate 304 serves as the proximity switch sensing area. When the arc-shaped steel plate 304 touches and overlaps with the switch sensor, a signal will be sent back to the host computer to protect and stop the belt.

[0029] like Figure 1-6As shown in the embodiment of this application, an adhesive tape 301 is provided on the other side of the arc-shaped steel plate 304. The adhesive tape 301 is located on the outer wall of several hooks 303 and is located in the limiting groove on the hooks 303. The hooks 303 are located on one side of the strip column 203. Specifically, several hooks 303 are arranged at intervals on one side of the strip column 203. The top of the hook 303 near the strip column 203 is provided with a limiting groove. The adhesive tape 301 is provided with several slots that are adapted to the hooks 303. The operator puts the slots on the adhesive tape 301 onto the outer wall of the hook 303 and slides it along the hook 303. When it slides to the end of the hook 303, the adhesive tape 301 will move into the limiting groove. Under the influence of gravity, the conveyor belt 301 is confined within the limiting groove on the hook 303. The conveyor belt 301 is easily disassembled and replaced on the outer wall of the hook 303. The conveyor belt 301 is the same width as the conveyor belt of the belt conveyor 1, and its height is maintained at a state where it is about to contact the non-working surface of the conveyor belt 301. When a small amount of coal appears on the non-working surface and comes into contact with the conveyor belt 301, the conveyor belt 301 will drive the rotating shaft 202 to shift at an angle through the strip column 203, thereby driving the arc-shaped steel plate 304 at the other end of the fixed rod 305 to rotate. It should be noted that the conveying direction of the belt conveyor 1 is from the rotating shaft 202 towards the switch sensor 302.

[0030] like Figure 1-6 As shown in the embodiments of this application, when transporting coal using the belt conveyor 1, a coal blockage may occur. When a blockage occurs, loose coal pieces will fall into the non-working surface and come into contact with the conveyor belt 301. As a result, the loose coal pieces will be driven by the conveyor belt 301 to rotate the strip column 203. During the rotation of the strip column 203, the rotating shaft 202 will be driven to rotate simultaneously. During the rotation of the rotating shaft 202, the rotating shaft 202 will drive the arc-shaped steel plate 304 at the other end of the fixed rod 305 to rotate. During the rotation of the arc-shaped steel plate 304, it will come into contact with the switch sensor 302. As a result, the switch sensor 302 will send a signal back to the control system, and then the control room will issue a voice alarm reminder to notify the inspection personnel to investigate the cause as soon as possible. If the trigger signal is held for more than 3 seconds, the belt protection shutdown procedure will be executed to effectively prevent and reduce safety production accidents.

[0031] In summary, this utility model discloses a conveyor belt anti-coal-stacking device, including a disassembly assembly 2, which is set on both sides of the frame of the belt conveyor 1 for disassembling and replacing the rotating shaft 202. A detection assembly is set on the outside of the rotating shaft 202 for detecting coal blockage at the working surface of the belt conveyor 1. With the setting of the cross bar 204 and the screw 205, it is convenient for workers to install the rotating shaft 202 and the strip column 203, and it is also convenient to disassemble and replace them. With the setting of the insertion rod 206, the rotating shaft 202 can be limited to prevent the rotating shaft 202 from sliding and deviating inside the fixed seat 201. With the cooperation between the belt 301 and the hook 303, it is convenient to disassemble and replace the belt 301. When the belt 301 rotates, it will synchronously drive the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it will drive the arc-shaped steel plate 304 to coincide with the switch sensor, thereby protecting the belt conveyor 1 through the control system and improving the safe operation of the equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
