Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a safety protection device for a coal mine belt conveyor. Background Technology

[0002] A belt conveyor is a mechanical device for continuous material transport, mainly consisting of a conveyor belt, idlers, drums, and tensioning devices. It is the ideal high-efficiency continuous transport equipment for the coal mining industry and can also be applied to other industries such as metallurgy, port transportation, and building materials. It can achieve long-distance, steeply inclined conveying, and allows for material loading or unloading at any point on the conveyor belt. It features high production efficiency, large conveying capacity, and low energy consumption.

[0003] In existing technology, coal mine belt conveyors include conveyor rollers and conveyor belts. During the conveying process of coal mines on the conveyor belt, due to the lack of material protection structures on the front and rear sides of the conveyor belt, coal can easily fall accidentally from the front and rear sides of the conveyor belt, which will cause a lot of conveying troubles. Moreover, during long-term use, due to friction and other factors, the temperature of the conveyor belt will increase significantly after a long period of use. Long-term high-temperature use will reduce the service life of the conveyor belt and easily cause problems such as breakage, posing a significant safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety protection device for coal mine belt conveyors, which solves problems such as coal easily falling accidentally from the front and rear sides of the conveyor belt and the conveyor belt easily breaking due to high temperatures.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety protection device for a coal mine belt conveyor, comprising a conveyor body and a base, wherein the base is fixed to the lower end of the conveyor body;

[0006] The conveyor body is equipped with protective baffles at both the front and rear. The upper end of the base is fixed with fixed plates at both the front and rear. A support plate is fixed between the upper ends of the two fixed plates. Lifting plates are fixed on the outer side of the protective baffles. Electric cylinders are connected between the lifting plates and the adjacent support plates.

[0007] A cold water tank is fixed to the lower end of the support plate, and a cooling protection component is provided below the cold water tank;

[0008] A hydraulic cylinder is fixed to the upper end of the base, and a lifting platform is connected to the power end of the hydraulic cylinder. A dust removal component is provided above the lifting platform.

[0009] Preferably, each of the lifting plates is connected to an adjacent support plate by two telescopic rods distributed in a left-right pattern.

[0010] Preferably, the cooling protection component includes a water pump, a control valve, a diversion pipe, and several atomizing nozzles. The water pump is connected to the lower end of the cold water tank, and the control valve is connected to the outlet of the water pump.

[0011] Preferably, the diversion pipe is connected to the outlet of the control valve, and the atomizing nozzles are all connected to the lower end of the diversion pipe.

The vacuum cleaner is fixed to the upper end of the lifting platform, the suction pipe is connected to the suction port of the vacuum cleaner, and the cleaning brush is fixed to the middle of the upper end of the suction pipe.

[0013] Preferably, the dust hoods are connected to the left and right sides of the dust suction pipe.

[0014] This utility model provides a safety protection device for a coal mine belt conveyor, which has the following beneficial effects:

[0015] By installing protective baffles on both the front and rear sides of the conveyor body, the coal being transported can be blocked and protected, reducing the possibility of accidental falls during transport.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a safety protection device for a coal mine belt conveyor, including a conveyor body 1 and a base 2. The base 2 is fixed to the lower end of the conveyor body 1. Protective baffles 5 are provided at both the front and rear of the conveyor body 1. Fixed plates 3 are fixed at both the front and rear of the upper end of the base 2. A support plate 4 is fixed between the upper ends of the two fixed plates 3. Lifting plates 6 are fixed to the outer side of the protective baffles 5. Electric cylinders 7 are connected between each lifting plate 6 and the adjacent support plate 4. Two telescopic rods 8 distributed left and right are connected between each lifting plate 6 and the adjacent support plate 4.

[0025] By installing protective baffles 5 on both the front and rear sides of the conveyor body 1, when it is necessary to block and protect the coal being transported, the extension of the electric cylinder 7 drives the lifting plate 6 and the protective baffle 5 to move upward until the protective baffle 5 can block and protect the front and rear sides of the conveyor body 1. This facilitates the blocking and protection of the coal being transported, reducing the occurrence of accidental falls during the transport process. When the protective baffle 5 is not needed, the retraction of the electric cylinder 7 drives the lifting plate 6 and the protective baffle 5 to move downward until the protective baffle 5 no longer blocks the front and rear sides of the conveyor body 1. Since the lifting plate 6 stretches or compresses the telescopic rod 8 when moving up and down, the telescopic rod 8 provides auxiliary support for the protective baffle 5, which helps to ensure the balance of the support for the protective baffle 5.

[0026] In this embodiment, a cold water tank 9 is fixed at the lower end of the support plate 4. A cooling protection component is provided below the cold water tank 9. The cooling protection component includes a water pump 11, a control valve 10, a diversion pipe 12, and several atomizing nozzles 13. The water pump 11 is connected to the lower end of the cold water tank 9. The control valve 10 is connected to the outlet of the water pump 11. The diversion pipe 12 is connected to the outlet of the control valve 10. The atomizing nozzles 13 are all connected to the lower end of the diversion pipe 12.

[0027] When it is necessary to cool down the conveyor belt on the conveyor body 1, the cold water in the cold water tank 9 is pumped to the control valve 10 by the water pump 11. With the control valve 10 open, the water is delivered to the diversion pipe 12 and the atomizing nozzle 13. Then, the water is sprayed onto the conveyor belt on the conveyor body 1 through the atomizing nozzle 13 to cool it down. This helps to prevent the conveyor belt from breaking due to high temperature and extends the service life of the conveyor belt.

[0028] In this embodiment, a hydraulic cylinder 14 is fixed to the upper end of the base 1. The power end of the hydraulic cylinder 14 is connected to a lifting platform 15. A dust removal assembly is provided above the lifting platform 15. The dust removal assembly includes a vacuum cleaner 16, a suction pipe 17, a cleaning brush 18, and several dust hoods 19. The vacuum cleaner 16 is fixed to the upper end of the lifting platform 15. The suction pipe 17 is connected to the suction port of the vacuum cleaner 16. The cleaning brush 18 is fixed to the middle of the upper end of the suction pipe 17. The dust hoods 19 are all connected to the left and right sides of the suction pipe 17.

[0029] When it is necessary to clean the dust on the surface of the conveyor belt, the extension of the hydraulic cylinder 14 drives the lifting platform 15, the vacuum cleaner 16, and the cleaning brush 18 to move upward until the cleaning brush 18 contacts the surface of the conveyor belt. When the conveyor body 1 drives the conveyor belt to work, the cleaning brush 18 helps to clean the coal dust on the surface of the conveyor belt. Combined with the work of the vacuum cleaner 16 and the dust hood 19, since the dust hood 19 is set on both sides of the cleaning brush 18, multiple dust hoods 19 help to absorb the coal dust swept down, and then absorb it into the vacuum cleaner 16 through the suction pipe 17 for collection. Therefore, it is beneficial to absorb and process the cleaned coal dust, thereby effectively reducing the trouble of manually cleaning the conveyor belt on the conveyor body 1. When it is not necessary to clean the conveyor belt, the retraction of the hydraulic cylinder 14 drives the lifting platform 15, the vacuum cleaner 16, and the cleaning brush 18 to move downward until the cleaning brush 18 is no longer in contact with the conveyor belt, avoiding the cleaning brush 18 from being in continuous contact with the conveyor belt, so as to prevent the cleaning brush 18 from being worn and damaged due to long-term contact with the conveyor belt.

[0030] Working principle;

[0031] The extension of the electric cylinder 7 drives the lifting plate 6 and the protective baffle 5 to move upward until the protective baffle 5 can cover and protect the front and rear sides of the conveyor body 1. The water pump 11 pumps the cold water in the cold water tank 9 to the control valve 10. With the control valve 10 open, the water is delivered to the diversion pipe 12 and the atomizing nozzle 13. Then, the atomizing nozzle 13 sprays water on the conveyor belt of the conveyor body 1 to cool it down. The extension of the hydraulic cylinder 14 drives the lifting platform 15, the vacuum cleaner 16 and the cleaning brush 18 to move upward until the cleaning brush 18 contacts the surface of the conveyor belt. When the conveyor body 1 drives the conveyor belt to work, the cleaning brush 18 helps to clean the coal dust on the surface of the conveyor belt. Combined with the work of the vacuum cleaner 16 and the dust hood 19, the multiple dust hoods 19 help to absorb the swept coal dust, and then absorb it into the vacuum cleaner 16 through the dust suction pipe 17 for collection.

[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 claims and their equivalents.
