Description

Technical Field

[0001] The invention relates to a scraper conveyor scraper monitoring device, in particular to a scraper conveyor scraper monitoring device with an adjustable cleaning function. Background Art

[0002] A scraper conveyor is a conveyor that uses a scraper chain to pull bulk materials through a trough. A scraper conveyor uses an open chute as a support for coal, gangue, or other materials, with scrapers attached to a chain (forming the scraper chain) as the traction element. When the head transmission unit is activated, it drives the sprocket on the head shaft, causing the scraper chain to circulate and move the material along the chute until it is unloaded at the head of the machine. The scraper chain then loops around the sprocket in a stepless closed loop, completing the material conveyance. Scraper conveyors are widely used in coal mining.

[0003] When a scraper conveyor is used in coal mining, the scrapers on it will continue to move with the chain. During use, there will often be phenomena such as missing scrapers, broken scrapers, and bent scrapers. If the scraper conveyor's scrapers are not repaired in time, it will have a great impact on the normal use of the scraper conveyor. The scraper conveyor of the existing technology lacks a monitoring device for the scraper conveyor's scrapers, and manual inspection and maintenance of the scraper conveyor are required on a regular basis. Due to the limitations of the working environment and the structure of the scraper conveyor itself, it is impossible to make a good judgment on the condition of the scraper conveyor's scrapers, which is not conducive to the maintenance and use of the scraper conveyor, and reduces the stability of the scraper conveyor during coal mining.

The end of the movable rod 21 away from the movable plate 19 passes through the side wall of the top shell 11 and is fixedly connected to a roller 22. A spring 23 is sleeved on the movable rod 21. One end of the spring 23 is fixedly connected to the movable plate 19, and the other end of the spring 23 is fixedly connected to the inner side wall of the top shell 11. The inner side wall of the chute 1 matches the roller 22 and is evenly distributed and fixedly connected with a number of protrusions 28 to achieve the cleaning operation of the monitoring device 13, avoid the impact on the monitoring device 13 during coal mining, and improve the monitoring accuracy of the scraper conveyor by this device;

[0036] The top surface of the top shell 11 is arc-shaped, and the thickness of the top surface of the top shell 11 is greater than the thickness of other surfaces of the top shell 11, thereby improving the protection of the device.

[0037] Among them, the inner cavity of the top shell 11 near the through groove 12 is fixedly connected with a sealing gasket 26 to prevent coal from entering the inner cavity of the top shell 11, thereby reducing the impact on the normal use of the device;

The monitoring operation can be realized through the infrared sensor, and the information can be sent through the wireless signal transmitter to realize real-time monitoring operation.

[0040] Working principle: Before use, the present invention first installs and debugs the device, places the mounting plate 6 on the scraper 4, and aligns the mounting plate 6 with the preset mounting hole 5 on the scraper 4. The device and the scraper 4 are fixed by bolts 7. Then, an external hexagonal wrench is inserted into the hexagonal slot 27 on the worm 15. The worm 15 is driven by the hexagonal wrench to rotate. The worm 15 engages with the worm wheels 16 on both sides to rotate. The worm wheels 16 drive the threaded rod 17 to rotate. The threaded rod 17 rotates in the threaded sleeve 18, so that the threaded sleeve 18 pushes the top shell 11 to move upward. When the monitoring device 13 in the top shell 11 moves to the specified height, stop rotating the worm 15 and pull out the hexagonal wrench. At this time, under the action of the spring 23, the rollers 22 are respectively pressed against the side walls on both sides of the chute 1, and the infrared sensing device in the monitoring device 13 is aligned with the infrared sensing devices on both sides thereof. A fixed value and sensing sensitivity of the horizontal position sensing of the infrared sensing device are set to complete the installation and debugging operation of the device. When in use, the device is started by an external power supply, and the chain 3 drives the scraper 4 to move in the chute 1. When an overload occurs, When the scraper 4 is damaged or bent, the distance between the infrared sensors of the adjacent monitoring devices 13 changes. At this time, the internal central processor starts the wireless signal sending device and sends the damage information of the designated scraper 4 position to the external host. The operator can respond and operate quickly. The machine can accurately realize the positioning operation of the damaged scraper 4, which is convenient for maintenance and use. In the process of the chain 3 driving the scraper 4 to move, the roller 22 on the scraper 4 moves closely with the inner wall of the chute 1. When the roller 22 moves to the position of the protrusion 28, the protrusion 28 lifts the roller 22, and the roller 22 drives the movable rod 21 to move. The movable rod 21 drives the movable plate 19 to move toward the side of the monitoring device 13. The cleaning brush 20 on the movable plate 19 is used to clean the monitoring device 13, thereby reducing the impact on the monitoring of the monitoring device 13, improving the accuracy of the monitoring, and having a good use effect.
