Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of coal mine cleaning technology, specifically, to a coal bunker cleaning device for mines. Background Technology
[0002] Coal bunkers are abundant in coal mines, divided into underground transportation system bunkers and surface coal preparation plant bunkers. They are crucial links in the underground transportation system and coal washing plant production, serving as important buffer nodes for coal transportation. When coal bunkers malfunction or experience accidents, it not only affects underground coal buffering and transportation but can also lead to the shutdown of the working face and disrupt normal surface coal washing operations. In severe cases, it can cause a complete mine shutdown and significant economic losses. The most common problem with both underground and surface coal bunkers is the adhesion of coal to the bunker walls. This reduces the effective volume of the bunker, causes arching at the bottom, and can even lead to blockage, seriously affecting the safe and efficient operation of the bunker. Therefore, to ensure the normal operation of the coal bunker, the adhesion of coal should be cleaned regularly.
[0003] According to a public announcement (Publication No.: CN 219097607 U), a mine coal bunker intelligent cleaning device consists of three parts: a lifting mechanism, a working platform, and a working robotic arm. It is suitable for cleaning various silos and uses wireless video monitoring and remote control technology to control the cleaning work of the equipment in the coal bunker. The robotic arm can be equipped with a variety of auxiliary tools and can be quickly replaced. It is suitable for automated cleaning and unblocking of coal bunkers in coal mines and can clean up blockages such as coal briquettes, coal stuck to the walls, and frozen coal.
[0004] Based on the cooperation between components such as the work platform and the robotic arm as disclosed in the public notice, it is difficult to solve the problems of not being able to clean the coal bunker by walking on its own and not being able to rotate to a 300-degree angle. This results in limited coal bunker cleaning capabilities and an inability to clean the coal bunker more directly and quickly, which needs to be improved. Utility Model Content

[0035] In some examples, the working head 327 is located on the inner wall of the coal bunker 1, and the side of the track frame 312 is provided with telescopic support legs 5, and the side of the boom 320 is provided with two boom cylinders 321. The design of the telescopic support legs 5 is conducive to supporting the cleaning device.
[0036] In some examples, there are several retractable support legs 5 arranged in pairs and symmetrical to each other along the vertical central axis of the track 310. The boom 320, second boom 322, and third boom 324 are located on the top of the track 310 and are equipped with several retractable support legs 5, which is beneficial for providing stable support for the device.
[0037] In some examples, the end of the lifting wire rope 31 away from the explosion-proof electric hoist 328 is fixedly connected to the top of the turntable 33, the track 310 is provided with two tracks, and the telescopic support leg 5 is provided with a bracket, cylinder and pin. This design is conducive to suspending the device.
[0038] In some examples, the motor is set as a three-phase asynchronous motor, and the monitoring device 38 includes a mine explosion-proof camera and an integrated mine explosion-proof and intrinsically safe display. The integrated mine explosion-proof and intrinsically safe display includes a video recorder, a large-capacity hard drive, a gigabit switch and a wireless mouse. The setting of the three-phase asynchronous motor is beneficial for use in coal mines and reduces the possibility of damage.
[0039] In some examples, the hydraulic cylinder is configured as a double-acting single-piston rod hydraulic cylinder for DG type vehicles. The internal components of the hydraulic cylinder include a cylinder body, nut, pin, plug, piston, seal ring, piston gasket, connecting pipe, copper sleeve, guide sleeve, threaded sleeve, piston rod, etc.
[0040] In some examples, the hydraulic circuit includes high-pressure hoses, articulated or crimped joints, and the electrical control system includes an internal control box 34 and an external control panel, with the control box 34 and control panel being explosion-proof and intrinsically safe.
[0041] In some examples, the hydraulic system includes an oil pump motor, an oil pump, a control valve assembly 39, a hydraulic motor, a hydraulic cylinder, a radiator, a hydraulic tank, and the rotary table 33 includes a hydraulic motor-driven worm gear reducer.
[0042] For example, such as Figures 1-7As shown in this application, the machine adopts a tracked 310 chassis, consisting of a base frame, a driving device, and a track tensioning device 311. This mechanism can withstand a large machine weight, has strong climbing ability, low ground pressure, and stable movement, and can adapt to steep slopes and sharp turns. The driving device has two tracks 310, each driven independently by two sets of driving devices, realizing the forward, backward, and turning movements of the entire machine. It can also make the entire machine rotate in place. The driving device has two tracks 310, each powered by a hydraulic motor, which drives the machine to move within the bin via a reducer. The support rollers 316 adopt advanced floating seals, ensuring smooth and reliable operation and saving time and effort in maintenance. The track tensioning device 311 consists of an idler wheel, a tensioning spring, and a tensioning cylinder. The tensioning device 311 is mainly used to maintain a certain tension of the track 310 and to provide cushioning during operation and travel. The idler wheel serves three main functions: steering, support, and tensioning of the track 310. The travel reducer 314 is a very compact transmission component with a built-in hydraulic motor. The track tensioning device 311 consists of an idler wheel, a tension spring, and a tension cylinder. The tensioning device 311 is mainly used to maintain a certain tension of the track 310 and to provide cushioning during operation and travel. To adjust the tension, use a high-pressure grease gun to inject grease into the tension cylinder, or unscrew the grease fitting before the check valve of the cylinder to drain the grease. Since the tension cylinder is under pressure under the action of the tension spring, opening the check valve should allow grease to drain. The working arm is one of the three main components of this machine. One of the components, its main function is to complete actions such as cleaning the coal bunker through lifting and swinging, thereby enabling coal cleaning operations on the inner wall of coal bunker 1. It is moved by the crawler 310, allowing for mobile coal cleaning operations. It is equipped with an explosion-proof suspension system. When cable laying is required, the operator sends a laying command to the drum through the control system. After receiving the command, the transmission device starts the motor, transmitting power to the drum body. Simultaneously, the brake device is released, allowing the drum to rotate. The cable is unwound from the drum and laid out along a predetermined path. Retrieving the cable is the reverse of the laying process. After sending a retrieval command through the control system, the transmission device starts the motor, causing the drum to rotate. Simultaneously, the brake device is released, and the cable begins to be wound back onto the drum. The system maintains tension and speed control during rotation. Precise tension control and cable routing devices prevent excessive stretching, twisting, and tangling of the cable during unwinding and rewinding, extending cable lifespan. It enables rapid and automatic cable unwinding and rewinding, reducing manual operation time and labor intensity, improving work efficiency, and effectively avoiding potential hazards such as sparks and static electricity generated during manual cable handling. This reduces the probability of explosions and fires. Compared to traditional manual cable cleaning, this equipment significantly saves labor costs and improves operational efficiency. Furthermore, it allows operators to work outside the coal bunker, improving the working environment and ensuring safe production. The foldable working arm and compact size make it suitable for on-site transportation.In operation, it meets the working requirements of a six-meter diameter coal bunker. The working arm can be equipped with components such as a bucket, cutting head, or impact hammer to meet different working conditions. The in-bunker machine adopts full hydraulic control and is equipped with a 1.5-ton steel tracked 310 chassis, allowing it to move independently. During operation, four outriggers extend to stabilize the machine body. The cleaning machine is equipped with a working turntable 33, which can rotate 300° for operation. It also has a jog function; each press rotates the machine by one degree, and a long press enables continuous operation. The equipment is equipped with limit switches to ensure controllable rotation angle. An explosion-proof suspension system is used to suspend the cleaning machine for operation. The coal cleaning machine features free and stable lifting and lowering. An external electrical control console for coal bunker 1 allows for remote operation, controlling the movement and actions of the machines within the bunker to complete the cleaning work. It includes gas monitoring and power-off functions to ensure safe operation. A video monitoring system, consisting of front-end equipment, a transmission network, and a back-end storage and control center, monitors the working conditions within the bunker. This system provides real-time monitoring, recording, storage, and playback functions. The entire machine is explosion-proof and can be used in locations containing methane mixtures, coal dust, or other explosive environments, and is designed for use within coal bunker 1.
[0043] like Figures 1-7 As shown, this invention illustrates a coal bunker cleaning device for mining, comprising an anti-jamming component 4 mounted on the top of a track 310. The anti-jamming component 4 includes a support rod 41, one end of which is fixedly connected to the side of the track 310. A control box 410 is fixedly connected to the side of the support rod 41. A fixing plate 43 is fixedly connected to the inner wall of the control box 410. A moving plate 42 is slidably connected to the inner wall of the control box 410. A push rod 44 is fixedly connected to the top of the moving plate 42. The end of the push rod 44 away from the moving plate 42 passes through the bottom of the control box 410. A drain pipe 49 passes through the top of the control box 410. An oil storage tank 411 passes through the end of the drain pipe 49 away from the control box 410. A short pipe 48 passes through the top of the oil storage tank 411. An oil outlet pipe 45 passes through the side of the control box 410. Oil is discharged through the oil outlet pipe 45 to lubricate the travel reducer 314 and prevent it from jamming.
[0044] In some examples, a limit rod 46 is fixedly connected to the inner wall of the control box 410. The end of the limit rod 46 away from the control box 410 passes through the bottom of the moving plate 42. A spring 47 is fixedly connected to the inner wall of the control box 410. The end of the spring 47 away from the control box 410 is fixedly connected to the bottom of the moving plate 42. The design of the spring 47 is conducive to the automatic reset when the moving plate 42 is not squeezed.
[0045] For example, such as Figures 1-7As shown, the oil reservoir 411 contains lubricating oil. The oil reservoir 411 transmits the lubricating oil into the control box 410 via the drain pipe 49. When the travel reducer 314 experiences jamming, pressing the push rod 44 pushes it inwards into the control box 410. This movement of the push rod 44 pushes the moving plate 42, creating a gap in the middle of the two fixed plates 43. The lubricating oil from the oil reservoir 411 initially reaches the top of the two fixed plates 43 and the moving plate 42, while the oil outlet pipe 45 is located at the bottom of the two fixed plates 43 and the moving plate 42, preventing oil from flowing out. When the moving plate 42 moves and creates the gap, the lubricating oil flows through the gap to the bottom of the control box 410. The lubricating oil flows to the bottom of the control box 410 and then flows out through the oil outlet pipe 45. The oil outlet pipe 45 is located on the side of the travel reducer 314 to lubricate it. The design of the push rod 44 allows the user to easily adjust the flow of lubricating oil manually. When jamming occurs, the squeezing of the push rod 44 can make the flow of lubricating oil smoother, avoiding equipment failure due to lack of lubricating oil, thereby reducing equipment downtime and improving production efficiency. By adjusting the gap between the moving plate 42 and the fixed plate 43, the lubricating oil can flow to the bottom of the control box 410 as needed and be accurately delivered to the travel reducer 314 through the oil outlet pipe 45. This design makes the distribution of lubricating oil more precise, avoids waste, and effectively prevents problems such as lubricating oil leakage or insufficient lubricating oil.
