Description

Technical Field

[0001] This invention belongs to the technical field of short-distance material transfer operations in underground coal mine tunneling faces, specifically relating to a mobile scraper transfer machine for coal mine roadways. Background Technology

[0002] With the continuous advancement of efficient and intensive mining, the monthly advance of the working face has reached 100-300m, and the monthly consumption of preparation roadways has also reached over 1000m. When the tunneling face is being opened, the subsequent supporting equipment is too long, making it impossible to arrange and use it in the first 50-100m of the roadway, thus failing to form a complete transportation system.

[0003] To promptly remove coal and rock after tunneling, material transport vehicles and transfer conveyors are needed to transfer materials to the main transport or roadway belt conveyors. Traditional transfer methods primarily involve material transport vehicles combined with belt transfer conveyors. However, when used as temporary transfer equipment, belt transfer conveyors suffer from difficulties in movement, small incline angles, and poor starting performance under heavy loads. These issues hinder smooth material transfer, reduce tunneling efficiency, and cause difficulties in transporting or changing transfer points, resulting in long auxiliary work hours and high labor intensity for workers. There is an urgent need to develop a mobile transfer equipment that is adaptable, practical, and highly efficient to accelerate tunneling and achieve balanced development between mining and excavation. Summary of the Invention

[0040] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0041] like Figure 1 As shown: A mobile scraper conveyor for coal mine roadways includes a receiving section 1, an intermediate frame 3, an unloading section 8, a scraper chain 9, a left platform assembly 2, a right platform assembly 4, and a wheel assembly 5. The receiving section 1, the intermediate frame 3, and the unloading section 8 are connected in sequence. The receiving section 1 is inclined downwards to receive materials, and the unloading section 8 is raised upwards to unload materials downwards. The scraper chain 9 starts from the receiving section 1, passes through the intermediate frame 3, the unloading section 8, the head sprocket assembly 803 on the unloading section 8, and the tail shaft assembly 106 on the receiving section 1, and then returns to the receiving section 1 to form a scraper conveying system. The head sprocket assembly 803 is connected to the transport transmission section 807. The wheel assembly 5 is located below the intermediate frame 3. The left platform assembly 2 is installed on the left side of the intermediate frame 3 and integrates and installs an electrical control system. The right platform assembly 4 is installed on the right side of the intermediate frame 3 and integrates and installs a hydraulic system.

[0042] like Figure 2 As shown: The receiving section 1 adopts a split structure, including a left hopper 101, a main frame 102, a right hopper 105, a tail shaft assembly 106, and a tensioning cylinder 109; the main frame 102 is inclined at a 13° angle to the ground and is supported by a triangular structure at its bottom, which plays a role in stabilizing the machine body; the left hopper 101 and the right hopper 105 are installed on both sides of the main frame 102 by high-strength bolts, forming an opening with one end larger than the other and the top open. The hoppers have small ports connected to the intermediate frame 3. The left hopper 101 and right hopper 105 are constructed by welding inclined plates at different angles. The tail shaft assembly 106 is located at the end of the receiving section 1 and serves to redirect the scraper chain. The tail shaft assembly 106 is slidably mounted on the main frame 102 and is connected to the main frame 102 by a tension cylinder 109. Adjusting the front and rear positions of the tail shaft assembly 106 through the tension cylinder 109 adjusts the tension of the scraper chain 9. The anti-collision frame 110 is connected to the front end of the receiving section 1 by a pin and can be folded open to prevent collisions and facilitate coal cleaning.

[0043] A buffer chain 104 is installed at the feed inlet of the receiving section 1, which improves the instantaneous material receiving capacity of the hopper. An adjustable movable coal baffle 103 is installed at the small port of the hopper in the receiving section 1. The coal throughput of the transport chute is adjusted by adjusting the up and down position of the movable coal baffle 103 to prevent large pieces of coal and rock from blocking the transport chute. An auxiliary unloading device 10 is added to the front end of the receiving section 1 to facilitate the reverse approach and unloading of materials by the engineering vehicle.

[0044] like Figure 3 As shown: The main frame 102 has rectangular holes on both sides of the transport channel, which are closed by side cover plates 107. When the scraper chain gets stuck, the coal can be cleared through these holes. The receiving section 1 is designed with a fire extinguisher rack, a spray rack, and a lubrication integrated block, which serves to place the fire extinguisher 108, install the spray system, and lubricate the system. The tensioning of the tensioning cylinder 109 and the lubrication of the tail shaft assembly 106 are both connected to the lubrication blocks on both sides for centralized operation. The oil nozzle is equipped with a dust cap.

[0045] like Figure 4 As shown: The intermediate frame 3 adopts a "triangular" stable structure and is inclined at a 13° angle to the horizontal plane. The intermediate frame 3 includes a transport trough frame 302 and an upper connecting ear 301, a connecting plate 303, a vehicle axle connecting frame 304, and a lower connecting ear 305 fixed on the transport trough frame 302. The middle plate and bottom plate of the transport trough frame 302 are made of HARDOX450 wear-resistant plate, which not only meets the instantaneous transport capacity requirements of the transport trough width, but also improves its service life. The vehicle axle connecting frame 304 is connected to the wheel assembly 5. Parking auxiliary support devices 6 are configured in front of and behind the wheels to ensure the safe operation of the equipment. The connecting plate 303 is connected to the receiving part 1. The upper connecting ear 301 is hinged to the unloading part 8. The lower connecting ear 305 is connected to the unloading part 8 by a lifting cylinder 7. The height of the unloading part 8 is adjusted by the lifting cylinder 7. In addition, the lifting cylinder 7 is equipped with a locking valve to prevent automatic leakage.

[0046] like Figure 8 As shown: The unloading section 8 includes an unloading frame 801, a head sprocket assembly 803, a receiving hopper assembly 805, and a transport transmission section 807. The head sprocket assembly 803 is installed in the groove of the unloading frame 801, and the transport transmission section 807 is installed outside the unloading frame 801. The transport transmission section 807 includes a variable frequency motor and a reducer. The variable frequency motor drives the head sprocket assembly 803 to rotate via the reducer. The running speed of the scraper chain 9 can be adjusted by adjusting the motor speed, thereby adjusting the conveying capacity per unit time. The receiving hopper assembly 805 is installed at the end of the unloading port of the unloading section 8, serving to stabilize the unloading and prevent material spillage.

[0047] A spray mounting bracket 804 is installed on the unloading rack 801 at the unloading port. The specific spray direction can be adjusted by adjusting the installation position of the exhaust holes. The anti-penetration fence 808 is suspended and installed below the unloading rack 801. It can be folded and stored to prevent personnel from passing through at will when the equipment is running.

[0048] like Figure 9As shown, the head sprocket assembly 803 adopts a split structure design, including an end cover 8031, a bearing housing 8032, a small shaft 8033, a sprocket 8034, a half cover 8035, a drive shaft 8036, a key 8037, an adjusting shim group 8038, and a bearing 8039. The drive shaft 8036 and the sprocket 8034 transmit power through spline engagement. Two interlocking half covers 8035 form a shaft connecting the two sprockets 8034. This structure not only provides stable driving force for the scraper chain operation but also facilitates disassembly and maintenance, improving the efficiency of the equipment.

[0049] like Figure 7 As shown: Wheel assembly 5 consists of axle assembly 501 and tire assembly 502. Axle assembly 501 has service brake and parking brake functions to ensure the safety of the equipment during towing. Tire assembly 502 uses polyurethane-filled solid tires, which are suitable for the complex geological conditions of coal mine floors. This wheel assembly does not have driving capability; it only serves the functions of heavy-duty support and traction movement.

[0050] like Figure 5 As shown: The right platform assembly 4 includes a right platform frame 404 and a hydraulic operating valve 402 and an integrated pump station 403 mounted on the right platform frame 404; a protective cover 401 is installed on the outside of the hydraulic operating valve 402 and the integrated pump station 403 to protect the components; a curved plate 406 is installed at the rear of the protective cover 401 to install the ball valve of the spray system 12; a right rubber plate 405 is installed on the right platform frame 404 in front of and behind the tires of the wheel assembly 5; a right emergency stop button 407 is provided on the right platform assembly 4 outside the protective cover 401 for emergency stop safety.

[0051] like Figure 6 As shown, the integrated pump station 403 includes an oil tank 4031, an accumulator 4032, an integrated valve 4033, a motor 4034, a support cover 4035, a hydraulic pump 4037, and a hand pump 4038. A pressure gauge 4036 is installed on the integrated valve 4033, and an oil temperature and level gauge 4039 is installed on the oil tank 4031. This design reduces the hydraulic piping layout while improving the equipment's practicality and safety. Furthermore, the oil tank maintenance manhole is located on the right side of the pump station for easy daily cleaning and maintenance. The integrated pump station also integrates the hydraulic pump 4037 and the hand pump 4038, ensuring the hydraulic system has a manual pressure replenishment function in case of power failure, further improving the equipment's downhole adaptability.

[0052] like Figure 10As shown: The left platform assembly 2 includes a left platform frame 204 and a display 206 and an explosion-proof and intrinsically safe electrical control box 207 mounted on the left platform frame 204. A rear guard 202 is installed outside the display 206, and a front guard 201 is installed outside the explosion-proof and intrinsically safe electrical control box 207. An audible and visual alarm device 208 is installed at the rear of the front guard 201, and a left emergency stop button 203 is installed at the rear of the rear guard 202, which serves as a safety reminder and emergency stop. Left rubber plates 205 are installed on the left platform frame 204 in front of and behind the tires of the wheel assembly 5.

[0053] The electrical system communication interface adopts Ethernet or optical port, enabling remote monitoring and operation of fault information, normal equipment operating parameters such as voltage, current, switch status, and cylinder status, meeting the needs of digital mines for remote parameter setting, equipment control, and fault reset. Cameras are arranged at the front and rear of the machine body to observe the receiving area, unloading area, and operating area, with remote monitoring and data upload capabilities. An electronic fence alarm system is configured; when the equipment is powered on, it will continuously emit light and sound alarms when personnel approach from a distance of 1 meter. The entire machine is equipped with a 208 audible and visual alarm device, with adjustable alarm time and sound, and a Chinese start-up warning function. The alarm will be announced three times with the message "Conveyor starts (or equipment starts), please pay attention," and a warning light will be provided.

[0054] This embodiment describes a mobile scraper conveyor used in coal mine roadways as a temporary transfer point. It connects with the main conveyor or roadway belt conveyor to perform a transfer function. It is often used in conjunction with integrated tunneling teams. The transferred materials are mostly gangue and mudstone. When moving or changing transfer points, the equipment is lifted to the designated location by a power vehicle such as a shovel truck through the lifting lug at the front end of the receiving section 1. First, the operator operates the explosion-proof and intrinsically safe electrical control box 207 on the left side of the machine to start the integrated pump station 403. The operator controls the lifting cylinder 7 to adjust the height of the unloading section 8 to the appropriate position by operating the hydraulic operating valve 402, and opens the parking brake switch to ensure stable parking of the equipment. Then, the operator operates the explosion-proof and intrinsically safe electrical control box 207 to activate the equipment linkage sensing function. When the material car approaches the unloading point, the scraper chain 9 starts running; when the material car moves away, the scraper chain 9 stops running. Finally, the underground water supply is connected and the spray system is turned on to simultaneously remove dust from the receiving and unloading sections during the material conveying and transfer process.
