Description

Technical Field

[0001] The present invention relates to the technical field related to underground transportation in coal mines, and in particular to a terrain-adaptive rotatable dust-reducing belt transportation device for mines. Background Art

[0002] Currently, the use of mechanized and intelligent equipment in underground coal mines has made coal mining faster and faster. The mined coal blocks are transported to the loading point by conveyors and finally transported to the surface. The increase in coal mining speed will lead to constant changes in the coal block transportation route and dust generation at the transfer point. Workers need to constantly adjust the position of the conveyor according to the forward position of the coal mining machine and scraper conveyor. Frequent position adjustments will cause the conveyor to be constantly disassembled and assembled, which will consume a lot of workers' physical strength and time. In addition, due to the complex terrain of different mines, the height difference between the scraper conveyor and the conveyor is different, which will generate additional dust to pollute the working environment and endanger the health of the workers. To this end, we propose a mine-use adaptive terrain rotatable dust reduction conveyor device. Summary of the Invention

[0003] The present invention aims to provide a mine-use adaptive terrain rotatable dust reduction belt transport device, which can automatically adjust the position and transfer height difference according to the terrain and coal transportation route, and use pressure spray equipment to carry out dust reduction treatment, thereby reducing the work intensity of workers and reducing dust during transfer to a certain extent.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-6 As shown, a mine-use self-adaptive terrain rotatable dust reduction belt transport device includes a transport component, a moving component for driving the transport component to move, and a dust reduction component arranged on the transport component.

[0024] The conveyor assembly comprises a conveyor 1, a belt 2 mounted on the conveyor 1, and hydraulic legs 3 on either side of the feed end of the conveyor 1. The conveyor 1 utilizes a roller-type conveyor 1. The roller-type conveyor 1 is equipped with multiple parallel rollers, through which the belt 2 is conveyed, ensuring its stability during transport. The roller-type belt 2 conveyor 1 is constructed of high-strength materials, offering a high load-bearing capacity and impact resistance, meeting the demands of diverse operating conditions. It also exhibits excellent wear and corrosion resistance, effectively extending the conveyor belt's service life. The rollers utilize an advanced sealing structure to effectively prevent lubricant leakage and dust intrusion, ensuring long-term, stable operation.

[0025] The conveyor 1 is provided with a third driving member 17 for driving the belt 2. The third driving member 17 is arranged on the right side of the discharge end of the conveyor 1 and is connected to the roller in the conveyor 1 (this is the existing technology and will not be repeated here), thereby driving the transmission of the belt 2. The third driving member 17 adopts a rotary driving member, such as a motor, a hydraulic motor, or an internal combustion engine.

[0026] The connection between the hydraulic outrigger 3 and the conveyor 1 is equipped with a rotation mechanism for lowering the hydraulic outrigger 3 to contact the ground. This rotation mechanism includes a fourth drive member and a rotation shaft located at the output end of the fourth drive member, on which the hydraulic outrigger 3 is mounted. The hydraulic outrigger 3 is a multi-stage telescopic cylinder structure with pressure-sensing foot pads 15 at the ends, which are used to perform real-time leveling of the machine body. During coal transportation, the fourth drive member is rotated to direct the pressure-sensing foot pads 15 of the hydraulic outrigger 3 toward the ground, and the telescopic cylinder controls the extension of the hydraulic outrigger 3 until the pressure-sensing foot pads 15 contact the ground.

[0027] Hydraulic support legs 3 are set on both sides of the discharge end of the conveyor. When the conveyor is conveying, the hydraulic support legs 3 are rotated from a horizontal state to a vertical state, and the pressure sensing foot pads 15 are facing the ground. The height of the hydraulic support legs 3 is adjusted by the extension and contraction of the multi-stage telescopic cylinder, so that the pressure sensing foot pads 15 are in contact with the ground to form a stable support, ensuring that the conveyor is in a stable state and preventing the conveyor from tilting during transportation, which affects the transportation of coal.

[0028] The mobile component includes a frame chassis 4 connected to the transport component and crawler tires 5 for moving the frame chassis 4. A rotating platform 6 for driving the transport component to rotate is provided above the frame chassis 4, and the rotating platform 6 is provided on the rotation center of the frame chassis 4; a laser scanner 10 for scanning the working area to generate three-dimensional data is installed on the frame chassis 4 facing the working area.

[0029] The laser scanner 10 uses a terrestrial laser scanner 10, which is a scientific instrument that automatically obtains high-precision three-dimensional geographic coordinates through laser technology and has efficient and accurate stereo image data acquisition capabilities (this is existing technology and will not be repeated here).

[0030] Tracked tire 5 uses rubber tracks, suitable for soft or rugged terrain in coal mines. The rubber tracks offer low ground contact pressure, protecting the hard subsoil and preventing damage to arable land and paddy fields. They also offer strong traction, providing excellent performance under load. They also offer excellent passability and gradeability, adapting to various terrains, especially mountainous and hilly terrain. Compared to metal tracks, rubber tracks offer a smoother ride and greater adaptability. They also offer low noise and vibration, as the elasticity of the rubber ensures closer contact with the road surface, reducing noise.

[0031] The chassis 4 is bolted to the tracked tires 5 below. The tracked tires 5 are driven by a second drive element 14, which utilizes a rotary drive element, such as an electric motor, hydraulic motor, or internal combustion engine. In this embodiment, two second drive elements 14 are motors, each located inside the two tracked tires 5. The motors can be positioned front, rear, or center; in this embodiment, they are located rearward. The second drive element 14 drives the tracked tires 5, thereby driving the transport device. This drive element driving the tracked tires 5 is suitable for use in loose coal seams and muddy roads.

[0032] The bottom surface of the conveyor 1 is higher than the top surface of the crawler tire 5. The rotating platform 6 includes a slewing bearing 11 and a transmission gear 12. The transmission gear 12 is driven by a reducer connected to the output shaft of the first drive member 13. The engagement between the reducer and the transmission gear 12 enables precise control of 360° rotation. The first drive member 13 is located below the frame chassis 4. The output shaft passes through the frame chassis 4 and connects to the slewing bearing 11. The first drive member 13 and the reducer are both installed and protected in an installation box. The installation box's floor is higher than half the height of the crawler tire 5. The first drive member 13 is driven by a rotary drive, such as an electric motor, hydraulic motor, pneumatic drive device, or internal combustion engine.

[0033] A shock-absorbing rubber pad 16 is provided between the bottom of the conveyor and the rotating platform 6. During the transportation of coal blocks, the conveyor 1 is continuously vibrated. The shock-absorbing rubber pad 16 is installed between the roller position of the conveyor 1 and the rotating platform 6 to prevent the continuous vibration from damaging the device.

[0034] The height adjustment of the hydraulic support legs 3 can also be performed by the laser scanner 10 , and the height adjustment of the hydraulic support legs 3 is performed according to the situation of the ground scanned by the laser scanner 10 .

[0035] The dust reduction assembly includes a pipe support 7 disposed at the feed end of the transport assembly, a dust suppressant pipe disposed within the pipe support 7, a dust suppressant nozzle 8 connected to the dust suppressant pipe and extending out of the pipe support 7, a pressure spray pipe disposed within the pipe support 7, and a pressure spray nozzle 9 connected to the pressure spray pipe and extending out of the pipe support 7. The dust suppressant nozzle 8 faces the feed end of the conveyor 1, and the pressure spray nozzle 9 faces the discharge end of the conveyor 1. The dust suppressant pipe is connected to a dust suppressant storage tank via a metering pump, and the pressure spray is connected to a pressure spray storage tank (not shown) via a metering pump.

[0036] The dust suppressant pipe and dust suppressant nozzle 8 are arranged at the feed end of the transport component, and the coal dust on the surface of the coal flow is fixed by the dust suppressant. The pressure spray pipe and pressure spray nozzle 9 are arranged at the discharge end of the transport component, and finally the generation of dust is controlled at the transfer source, and the coal dust generated by the transfer of coal blocks is reduced.

[0037] The second drive member 14, the first drive member 13, and the third drive member 17 are all electrically connected to a controller, which controls the movement of the transport device, the steering of the transport component, and the transmission of the belt 2 to ensure the normal operation of the device; and the controller is also electrically connected to the laser scanner 10, the fourth drive member, the hydraulic cylinder and the pressure sensing foot pad 15 to control the lifting, lowering, and extension length of the hydraulic support leg 3. The laser scanner 10 transmits the scanning result signal to the receiver, the receiver transmits the signal to the processor for analysis, and the receiver transmits the signal to the controller, which controls the hydraulic support leg 3 (this is existing technology and will not be repeated here); the controller is also electrically connected to the dust suppressant storage tank, the pressure spray storage tank, and the metering pump to control the spraying of the dust suppressant and the pressure spray to reduce coal dust.

[0038] The mobile assembly composed of crawler tires 5 is used to ensure high passability and flexibility in complex terrain, realize the movement of the device and the function of adaptive terrain, and set up a rotating platform 6 to transport coal more conveniently and efficiently, effectively reduce the workload of operators and reduce the generation of coal dust; the coal transportation route, direction, angle, and the adjustment of the height difference between the transportation route and the transfer can be adjusted in time according to the situation during coal seam mining; the balance of the conveyor 1 is ensured by adjusting the height of the hydraulic support legs 3, and the stability of the coal transportation process is ensured; a dust suppressant pressure spray is set to fix the generation of coal dust on the surface of the coal flow, and a pressure spray is set to capture the scattered coal dust to suppress the generation of coal dust; the circular rotary support structure of the rotating platform 6 is set at the center position above the frame belt pulley to ensure the stability and balance of the conveyor 1 during the rotation process; the overall operation process can effectively reduce the generation of transfer coal dust and improve the working efficiency of operators.
