Description

Technical Field

[0001] The utility model relates to the technical field of automation and control, in particular to a transportation device used in mining. Background Art

[0002] The transportation device in mining is one of the key equipment in the mining production system, which is mainly used to transport ore, waste rock or other materials from the mining site to the designated location. Common transportation devices include conveyor belts, mine cars, trucks, etc. Among them, conveyor belts are widely used in mining transportation systems due to their advantages of continuous transportation, high efficiency and low cost.

[0003] However, existing conveyor belt technology has some problems during long-term use, especially the wear problem of conveyor belt thickness. Conveyor belts are usually made of multiple layers of materials, including rubber, fabric or wire rope, etc. These materials will gradually wear out under long-term heavy loads, friction and environmental influences. Wear will cause the thickness of the conveyor belt to decrease, which in turn affects its strength and durability. Since wear is difficult to detect, the conveyor belt may suddenly break after long-term use. This sudden breakage will not only cause production interruptions, but may also cause safety accidents, resulting in casualties and equipment damage. Most existing conveyor belt monitoring technologies rely on regular manual inspections of conveyor belts, and are unable to monitor the wear of conveyor belts in real time and accurately, resulting in the inability to take preventive measures in a timely manner.

[0004] Therefore, there is a particular need for a mine mining and transportation device that can be monitored in real time to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcoming that the existing conveyor belt monitoring technology cannot monitor the wear condition of the conveyor belt in real time and accurately, the utility model provides a transportation device for mining.

[0006] The utility model is realized through the following technical approaches: a transport device for mining, including a base, a first support frame, a conveyor belt, a cleaning mechanism and a monitoring mechanism, the top of the base is fixedly connected to the first support frame, the conveyor belt is installed on the first support frame, the cleaning mechanism is provided on the right side of the lower part of the conveyor belt, and the monitoring mechanism is provided on the left side of the lower part of the conveyor belt.

[0007] Furthermore, the cleaning mechanism includes a fixed frame, a sliding frame, a cleaning brush and a first spring. A front-to-rear symmetrical fixed frame is fixedly connected to the bottom of the first support frame. A sliding frame is slidably connected between the lower sides of the two fixed frames. A cleaning brush is rotatably mounted on the sliding frame. The surface of the cleaning brush is in close contact with the surface of the conveyor belt. A first spring that is symmetrical up and down is connected between the fixed frame and the sliding frame.

[0008] Furthermore, the monitoring mechanism includes a second support frame, a support block, a scale, a connecting block, a connecting frame, a roller and a second spring. The second support frame is fixedly connected to the left side of the bottom of the first support frame, and a support block with a transverse array is fixedly mounted on the second support frame. A front-to-rear symmetrical scale is provided on the left wall of the lower part of the support block. A connecting block is slidably connected to the lower side of the support block, and the connecting block is located between the two scales. A connecting frame is fixedly connected to the top of the connecting block, and the connecting frame is slidably connected to the upper side of the support block. A roller is rotatably mounted on the upper side of the connecting frame, and the surface of the roller is in close contact with the surface of the conveyor belt. A second spring is connected between the support block and the connecting block.

[0009] Furthermore, it also includes a connecting pipe and a spray nozzle. The front side of the first support frame is penetrated by a connecting pipe fixedly connected to a transverse array, and the upper end of the connecting pipe is fixedly connected to the spray nozzle.

[0010] Furthermore, it also includes a support plate, a sensor and an alarm. The support plate is fixedly connected to the lower side of the support block, the sensor is installed on the top of the support plate, the left side wall of the second support frame is fixedly connected to the front and rear symmetrical alarm, and the sensor is electrically connected to the alarm.

[0011] Furthermore, the conveyor belt is made of rubber.

[0012] From the above description of the structure of the utility model, it can be known that the design starting point, concept and advantages of the utility model are: 1. The monitoring mechanism of the utility model can monitor the wear of the conveyor belt in real time through the cooperation of components such as rollers, scales and sensors. When the conveyor belt is worn and thinned due to long-term use, the sensor will detect the position change of the connecting block and trigger the alarm when the critical value is reached. This intelligent early warning mechanism can promptly remind the operator to take preventive measures to avoid sudden breakage of the conveyor belt and ensure the safe operation of the transportation device.

[0013] 2. The utility model is provided with a cleaning mechanism and a spray nozzle. The cleaning mechanism can continuously clean the debris on the surface of the conveyor belt. At the same time, the water mist sprayed by the spray nozzle effectively washes the surface of ore, waste rock or other materials, significantly reducing the generation of dust. It not only improves the working environment, but also reduces the harm of dust to the health of operators, which meets the requirements of mine safety production.

[0014] 3. The utility model adopts rubber material for the conveyor belt, which has good wear resistance and tensile strength and can adapt to most mining environments. At the same time, the design of the cleaning mechanism and the monitoring mechanism has strong versatility and can be applied to conveyor belts of different specifications and a variety of mining transportation scenarios.

[0021] Embodiment: A transport device for mining, such as Figure 1-Figure 4 As shown, it includes a base 1, a first support frame 2, a conveyor belt 3, a connecting pipe 4, a spray nozzle 5, a cleaning mechanism and a monitoring mechanism. The first support frame 2 is welded on the top of the base 1, and the conveyor belt 3 is installed on the first support frame 2. The conveyor belt 3 is made of rubber material, has good wear resistance and tensile strength, and is suitable for most mining environments. A connecting pipe 4 with a transverse array is penetrated and fixed on the front side of the first support frame 2. The spray nozzle 5 is threadedly connected to the upper end of the connecting pipe 4, and the lower end of the connecting pipe 4 is connected to a water source. A cleaning mechanism is provided on the right side of the lower part of the conveyor belt 3 for cleaning debris on the surface of the conveyor belt 3, and a monitoring mechanism is provided on the left side of the lower part of the conveyor belt 3 for real-time monitoring of the wear of the conveyor belt 3.

[0022] like Figure 1 and Figure 2 As shown, the cleaning mechanism includes a fixed frame 6, a sliding frame 7, a cleaning brush 8 and a first spring 9. The bottom of the first support frame 2 is bolted to a front-to-back symmetrical fixed frame 6, a sliding frame 7 is slidably connected between the lower sides of the two fixed frames 6, a cleaning brush 8 is rotatably mounted on the sliding frame 7, the surface of the cleaning brush 8 is in close contact with the surface of the conveyor belt 3, and a first spring 9 is connected between the fixed frame 6 and the sliding frame 7, which is symmetrical up and down.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the monitoring mechanism includes a second support frame 10, a support block 11, a scale 12, a connecting block 13, a connecting frame 14, a roller 15, a second spring 16, a support plate 17, a sensor 18 and an alarm 19. The second support frame 10 is welded to the left side of the bottom of the first support frame 2. The second support frame 10 is sleeved with a support block 11 fixedly connected with a transverse array. The left side wall of the lower part of the support block 11 is provided with a scale 12 symmetrically arranged front and back. The lower side of the support block 11 is slidably connected with a connecting block 13, and the connecting block 13 is located between the two scales 12. In the middle, a connecting frame 14 is welded on the top of the connecting block 13, and the connecting frame 14 is slidably connected to the upper side of the support block 11. A roller 15 is rotatably connected to the upper side of the connecting frame 14, and the surface of the roller 15 is in close contact with the surface of the conveyor belt 3.
