Description

Technical Field

[0001] This utility model specifically relates to the field of coal mining technology, and more specifically to a coal and gangue boundary positioning and monitoring device based on laser scanning. Background Technology

[0002] The development of laser scanning coal and gangue boundary positioning and monitoring devices is an inevitable requirement for the coal industry to develop towards intelligence and efficiency, and it is also an important measure to address the shortcomings of existing coal and gangue identification technologies.

[0003] my country has abundant reserves of thick coal seams, and top coal caving mining is an important method for mining thick coal seams. Achieving unmanned production in fully mechanized top coal caving faces is an important direction for the development of the coal industry. Accurately judging the coal-gangue interface is the key to controlling the coal release time and realizing automatic control of the opening and closing of the coal release port, and it is the foundation for improving the automation and intelligence of top coal caving mining. The traditional method of relying on manual visual judgment of the degree of top coal release not only poses prominent safety issues for workers in the dusty and harsh environment of the coal mining face, but also easily leads to over-release and under-release during the coal release process. Therefore, there is an urgent need for automated coal-gangue boundary positioning and monitoring technology.

[0004] Currently, there are various methods for identifying coal and gangue, such as artificial gamma rays, natural gamma rays, vibration identification technology, laser dust photography, image information processing, and video camera technology. However, due to the complex underground environment, variable geological conditions, diverse coal discharge process parameters, and complex types of working face equipment, these single technical means are difficult to accurately determine the boundary between coal and gangue. The actual application effect is not ideal, the adaptability is poor, and they cannot meet the requirements of intelligent coal mining.

[0005] Traditional coal gangue sorting methods mainly rely on manual labor or simple mechanical devices, which have problems such as low sorting efficiency, poor accuracy, high energy consumption, and high labor demand. They may also lead to environmental pollution and resource waste, making it difficult to meet the needs of green and efficient development in the modern coal industry. Furthermore, traditional equipment cannot effectively adjust the angle during site selection, which may cause large errors and low work efficiency when dividing and positioning, thus affecting the construction progress. Utility Model Content

In this device, a laser transmitter emits a signal, and a laser receiver effectively receives the reflected signal, thereby effectively calculating the actual distance. During positioning detection, a handrail allows the placement frame to move along the guide groove via rollers, thereby effectively adjusting the angles of the laser receiver and laser transmitter on the mating seat and mounting seat inside the placement frame. This effectively expands the positioning detection range, thus better completing the site selection operation and improving production efficiency, thereby solving the problems mentioned in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A placement frame is provided between the two side plates; a mating seat is fixedly installed inside the placement frame; two laser receivers are installed on the mating seat; the mating seat is fixedly installed with the mounting base; a laser emitter is fixedly installed on the mounting base; the laser emitter effectively emits a detection signal, and after the signal bounces off the coal gangue, it is effectively received by the laser receiver, thereby effectively converting the signal reception time into distance, thus effectively ensuring the accuracy of boundary positioning detection.

[0010] As a further technical solution of this utility model, symmetrical rollers are movably installed on both sides of one end of the placement frame via a rotating shaft; the rollers are installed in conjunction with the guide groove; when the two guide wheels roll along the guide groove, they effectively ensure the stability of the placement frame and prevent the laser transmitter and laser receiver from shifting angles, thereby effectively ensuring signal transmission and reception.

[0011] As a further technical solution of this utility model, a handrail is fixedly installed at one end of the placement rack; the support plate with the handrail is fitted into the C-shaped groove on the horizontal plate between the two side plates; the angle of the placement rack can be effectively adjusted by the handrail, so as to realize the detection of different positions by the laser emitter and the laser receiver, which can effectively ensure work efficiency and improve production accuracy.

[0012] As a further technical solution of this utility model, locking rods are installed on both sides of the support plate; the locking rods are inserted and fixed to the ear plate on one side of the bottom of the mating seat; the locking rods effectively fix the mating seat, ensuring the stability of the laser emitter and the laser receiver, thereby effectively ensuring the accuracy of positioning detection.

[0013] As a further technical solution of this utility model, a support arm is movably installed at the bottom of the placement frame at the end away from the handrail; the end of the support arm away from the placement frame is movably installed with one end of the telescopic rod; through the cooperation between the support arm and the telescopic rod, the support effect of the placement frame after the angle adjustment is completed is effectively guaranteed, and the stability of the placement frame is guaranteed.

[0014] As a further technical solution of this utility model, the end of the telescopic rod away from the support arm is movably installed on the crossbeam of the movable frame through a rotating shaft and a connecting seat; a controller is fixedly installed on the side of the movable frame away from the telescopic rod; the controller is electrically connected to the laser transmitter and the laser receiver; the microcontroller inside the controller effectively realizes the transmission and reception of signals, and converts the time of signal transmission into distance, thereby effectively ensuring the accuracy of positioning detection.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the mounting base and the placement frame are fixedly installed during use, and then the mounting base and the placement frame are fixedly installed to ensure that the laser receiver and the laser emitter are always in the same plane. The controller enables the laser emitter to generate a scanning signal, and the signal is effectively received by the laser receiver after it bounces back. The microcontroller inside the controller automatically converts time into distance, thereby effectively ensuring the accuracy of positioning detection.

[0017] In this utility model, during use, the placement frame is swung by the handrail. When the placement frame swings, the cooperation between the rollers on both sides and the guide grooves opened on the side plate effectively ensures the stability of the placement frame during movement and the stability of the laser emitter and laser receiver.

The telescopic rod is movably connected to one end of the bottom of the placement frame through the support arm, effectively ensuring the support effect after the angle adjustment is completed, thereby ensuring that the signal emitted by the laser transmitter can be received by the laser receiver after it bounces back, thus ensuring the accuracy of the operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 In this embodiment of the utility model, the coal gangue boundary positioning and monitoring device based on laser scanning includes a mobile frame 1; two symmetrical side plates 5 are fixedly installed on the top of the mobile frame 1; arc-shaped grooves are opened on the two side plates 5; a horizontal plate between the two side plates 5 is fixedly installed on the top of the mobile frame 1, and two C-shaped grooves are opened on the top of the horizontal plate.

[0029] A placement frame 13 is provided between the two side plates 5; a mating seat 12 is fixedly installed inside the placement frame 13; two laser receivers 3 are installed on the mating seat 12; the mating seat 12 is fixedly installed with a mounting base 4; a laser emitter 2 is fixedly installed on the mounting base 4.

[0030] The placement rack 13 has symmetrical rollers 9 mounted on both sides of one end via a pivot shaft; the rollers 9 are installed in conjunction with the guide groove 6.

[0031] By adopting the above technical solution, during use, the mounting base 12 and the placement frame 13 are fixedly installed, and then the mounting base 4 and the placement frame 13 are fixedly installed to ensure that the laser receiver 3 and the laser emitter 2 are always in the same plane. The laser emitter 2 generates a scanning signal through the controller 8. After the emitted signal is reflected, it is effectively received by the laser receiver 3. The microcontroller inside the controller 8 automatically converts time into distance, thereby effectively ensuring the accuracy of positioning detection.

[0032] In this embodiment, a handrail 10 is fixedly installed at one end of the placement rack 13; the support plate on which the handrail 10 is installed fits into the C-shaped groove opened on the horizontal plate between the two side plates 5.

[0033] In this embodiment, locking rods 14 are installed on both sides of the support plate; the locking rods 14 are inserted and fixed to the ear plate on one side of the bottom of the mating seat 12.

[0034] By adopting the above technical solution, during use, the handrail 10 drives the placement frame 13 to swing. When the placement frame 13 swings, the cooperation between the rollers 9 on both sides and the guide grooves 6 opened on the side plate 5 effectively ensures the stability of the placement frame 13 during movement and the stability of the laser emitter 2 and the laser receiver 3.

[0035] Furthermore, a support arm 11 is movably installed at the bottom of the placement frame 13 at the end away from the handrail 10; the end of the support arm 7 away from the placement frame 13 is movably installed at one end of the telescopic rod 7.

[0036] In this embodiment, the end of the telescopic rod 7 away from the support arm 11 is movably installed to the crossbeam of the movable frame 1 via a pivot and a connecting seat; a controller 8 is fixedly installed on the side of the movable frame 1 away from the telescopic rod 7; the controller 8 is electrically connected to the laser emitter 2 and the laser receiver 3.

[0037] By adopting the above technical solution, when adjusting the angle of the placement frame 13, the locking rod 14 is effectively inserted and fixed to the placement frame 13, avoiding the separation of the mating seat 12 from the mounting seat 4 and the placement frame 13 during angle adjustment. The telescopic rod 7 is movably connected to one end of the bottom of the placement frame 13 through the support arm 11, effectively ensuring the support effect after the angle adjustment is completed, thereby effectively ensuring that the signal emitted by the laser transmitter 2 can be received by the laser receiver 3 after it bounces back, thus ensuring the accuracy of the work.

[0038] The working principle of this utility model is as follows: When in use, the mating seat 12 and the placement frame 13 are fixedly installed, and then the mounting seat 4 and the placement frame 13 are fixedly installed to ensure that the laser receiver 3 and the laser emitter 2 are always in the same plane. The laser emitter 2 generates a scanning signal through the controller 8. After the emitted signal is reflected, it is effectively received by the laser receiver 3. The microcontroller inside the controller 8 automatically converts time into distance, thereby effectively ensuring the accuracy of positioning detection.

[0039] During use, the placement frame 13 is swung by the handrail 10. When the placement frame 13 swings, the rollers 9 on both sides cooperate with the guide grooves 6 opened on the side plate 5 to effectively ensure the stability of the placement frame 13 during movement and the stability of the laser emitter 2 and the laser receiver 3.

[0040] When adjusting the angle of the placement frame 13, the locking rod 14 is effectively inserted and fixed to the placement frame 13 to prevent the mating seat 12 from separating from the mounting seat 4 and the placement frame 13 during angle adjustment. The telescopic rod 7 is movably connected to one end of the bottom of the placement frame 13 through the support arm 11, which effectively ensures the support effect after the angle adjustment is completed, thereby ensuring that the signal emitted by the laser transmitter 2 can be received by the laser receiver 3 after it bounces back, thus ensuring the accuracy of the operation.
