Description

Technical Field

[0001] This utility model relates to the field of fly ash, specifically a fly ash solid waste covering device. Background Technology

[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged by coal-fired power plants. If large amounts of fly ash solid waste are not properly treated, they will cause serious environmental pollution, such as dust pollution of the air and damage caused by seeping into the soil and water. At present, one of the ways to treat fly ash solid waste is to cover it to reduce its adverse environmental impact. The covering device is installed on a mobile vehicle, which moves the covering device to facilitate the covering work.

[0003] Existing covering devices have small storage capacity and require frequent replenishment of covering materials, which interrupts the operation. For example, some small storage boxes may need to be stopped every once in a while to replenish materials when covering large areas of fly ash. Moreover, replacing new materials is time-consuming and affects covering efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fly ash solid waste covering device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fly ash solid waste covering device, comprising a support frame, which performs covering work by moving. A rotating frame is installed at the upper end of the support frame, and several rotating rods arranged in a circle are installed at the outer end of the rotating frame. Limiting components for preventing the rotating rods from falling off are installed on both sides of the rotating frame. A rotating wheel for installing the covering roll is installed on the outer surface of each rotating rod. A groove is opened at one end of each rotating rod, and a polygonal slider for positioning the rotating rod is slidably connected inside one of the grooves. A driving mechanism for driving the polygonal slider to rotate is installed at the bottom of the support frame.

[0006] Preferably, the limiting assembly includes a fixed sleeve, a fixed block, a spring B, and a limiting rod. The rotating rod is slidably and rotatably connected to the fixed sleeve, the fixed block is fixedly connected to the rotating frame, the limiting rod passes through the fixed block and is slidably connected to the fixed block, and the two ends of the spring are fixedly connected to the limiting rod and the fixed block, respectively.

[0007] Preferably, each of the rotating frames includes a rotating column, a turntable, and two symmetrical mounting brackets. The mounting brackets are fixedly connected to the rotating column, the rotating rod is slidably and rotatably connected to the mounting brackets, and the turntable is fixedly connected to the rotating column.

[0008] Preferably, each of the two mounting brackets has a plurality of balls rotatably mounted on one side that is close to each other, and each ball is in contact with the adjacent rotating wheel.

[0009] Preferably, the driving mechanism includes a motor, a rotating block, a connecting block, and a spring A. The two ends of the spring A are fixedly connected to the rotating block and the connecting block, respectively. The motor is fixedly connected to the bracket, and its output end is fixedly connected to the rotating block. A polygonal slot is opened inside the rotating block, and a polygonal slider is slidably connected to the slot. The connecting block is fixedly connected to the polygonal slider.

[0010] Preferably, a limiting groove is formed inside the rotating rod, and a limiting block is slidably connected inside the limiting groove, with the limiting block being fixedly connected to the rotating wheel.

[0011] Compared with the prior art, this utility model has the following advantages: the covering roll is installed on the outer surface of the rotating wheels, and several rotating wheels are arranged in a circle. When a new covering roll needs to be replaced, it is only necessary to disengage the polygonal slider from the rotating rod, and the next rotating wheel can be rotated to the working area by rotating the rotating frame. Moreover, it can achieve the purpose of automatic positioning, so that the rotating wheels can release the covering roll and cover the fly ash solid waste. Whenever the roll is used up, several rotating wheels and the covering roll on their surface can be installed quickly and sequentially in this way. Moreover, during the covering work, the rotating wheels with used covering rolls in other positions can also be replaced without affecting the work process, thereby improving the efficiency of the covering work.

[0021] like Figures 1-8As shown, a fly ash solid waste covering device includes a support frame 1. This covering device performs covering work by movement. A rotating frame 2 is installed at the upper end of the support frame 1. Each rotating frame 2 includes a rotating column 201, a turntable 202, and two symmetrical mounting frames 203. The mounting frames 203 are fixedly connected to the rotating column 201. A rotating rod 3 is slidably and rotatably connected to the mounting frames 203. The turntable 202 is fixedly connected to the rotating column 201. The rotating column 201 is located at the center of the turntable 202. By rotating the turntable 202, the mounting frames 203 can rotate, thereby causing several rotating wheels 5 to rotate around the rotating column 201. The outer surface of the mounting frames 203 has a raised structure. Several rollers are rotatably mounted on the side of the two mounting frames 203 that are close to each other. Each ball 9 contacts its adjacent rotating wheel 5. The ball 9 prevents the rotating wheel 5 from shifting and facilitates its smoother rotation. Several rotating rods 3 arranged in a circle are installed on the outer end of the rotating frame 2. Limiting grooves 11 are formed inside the rotating rods 3, and limiting blocks 12 are slidably connected inside the limiting grooves 11. The limiting blocks 12 are fixedly connected to the rotating wheel 5. There are two limiting grooves 11 and two limiting blocks 12. When the rotating rods 3 rotate, they drive the limiting blocks 12 to rotate, which in turn drives the rotating wheel 5 to rotate. Limiting components 4 are installed on both sides of the rotating frame 2 to prevent the rotating rods 3 from falling off. The limiting components 4 include a fixing sleeve 401, a fixing block 402, a spring B, and a limiting rod 403. The spring B is in a static state. The moving rod 3 is slidably and rotatably connected to the fixed sleeve 401. The fixed block 402 is fixedly connected to the rotating frame 2. The limiting rod 403 passes through the fixed block 402 and is slidably connected to the fixed block 402. The two ends of the spring are fixedly connected to the limiting rod 403 and the fixed block 402 respectively. When the fixed sleeve 401 is separated from the limiting rod 403 and the rotating rod 3, it is easy to remove the rotating rod 3 and the rotating wheel 5. The outer surface of each rotating rod 3 is equipped with a rotating wheel 5 for installing the cover roll. The cover roll is installed on the outer surface of the rotating wheel 5. One end of each rotating rod 3 is provided with a groove 8. A polygonal slider 6 for positioning the rotating rod 3 is slidably connected inside one of the grooves 8. The bottom of the bracket 1 is equipped with a drive mechanism for driving the polygonal slider 6 to rotate. 7. The drive mechanism 7 includes a motor 701, a rotating block 702, a connecting block 703, and a spring A. Both ends of the spring A are fixedly connected to the rotating block 702 and the connecting block 703, respectively. The motor 701 is fixedly connected to the bracket 1, and its output end is fixedly connected to the rotating block 702. A polygonal slot is formed inside the rotating block 702, and a polygonal slider 6 is slidably connected to the slot. The connecting block 703 is fixedly connected to the polygonal slider 6. When the spring A is static, the polygonal slider 6 is located in the groove 8 and in contact with the adjacent rotating rod 3. When the motor 701 starts, it drives the rotating block 702 to rotate, which in turn drives the polygonal slider 6 to rotate, thereby causing the polygonal slider 6 to drive the rotating rod 3 to rotate, facilitating the release of the cover material. During the rotation of the rotating rod 3...Spring A prevents the polygonal slider 6 from disengaging from the groove 8. A support frame 10 for supporting the rotating block 702 is fixedly mounted at one end of the bracket 1, and the rotating block 702 is rotatably connected to the support frame 10.

[0022] Working principle:

[0023] First, the bracket 1 needs to be installed on the mobile vehicle. The mobile vehicle moves the bracket 1. At this time, the motor 701 is started to drive the rotating block 702 to rotate. The rotating block 702 drives the polygonal slider 6 to rotate. The polygonal slider 6 drives the rotating rod 3 to rotate. When the rotating rod 3 rotates, it drives the limiting block 12 to rotate. The limiting block 12 drives the rotating wheel 5 to rotate, which facilitates the release of the covering roll installed on the surface of the rotating wheel 5. The covering roll covers the fly ash solid waste to reduce the adverse environmental impact of fly ash solid waste. During the rotation of the rotating rod 3, the spring A has elasticity and makes the connecting block 703 contact the rotating rod 3, improving the stability of the connecting block 703. The connecting block 703 is fixed to the polygonal slider 6, which can prevent the polygonal slider 6 from detaching from the slide groove 8.

[0024] Next, when the cover material on the surface of the rotating wheel 5 is used up, the connecting block 703 is pulled towards the motor 701, causing the connecting block 703 to remove the polygonal slider 6 from the slot, thus releasing the limiting effect of the polygonal slider 6 on the rotating rod 3. Then, the turntable 202 is rotated, causing the rotating column 201 to rotate. The rotating column 201 drives the two mounting brackets 203 to rotate, and the two mounting brackets 203 drive several rotating rods 3 and rotating wheels 5 to rotate around the rotating column 201 as the center, rotating the rotating wheel 5 away from the position of the polygonal slider 6. At this time, the next rotating wheel 5 should rotate to a position concentric with the polygonal slider 6 and the rotating block 702, i.e., the working area. Then, the polygonal slider 6 is reinserted into the slot of the rotating rod 3 to complete the positioning of the rotating rod 3, and thus complete the positioning of the rotating wheel 5, preventing the rotating wheel 5 from shifting. Then, the covering work continues, making the work change relatively simple and quick. Since several rotating rods 3 are arranged in a circle, whenever the cover material at the rotating wheel 5 is used up... Afterwards, new cover rolls can be quickly replaced using the aforementioned rotation method. Furthermore, due to the significant weight of traditional large-roll cover rolls, traditional covering devices require multiple people to lift them. Installing new rolls in the work area is time-consuming and labor-intensive, resulting in prolonged interruptions and hindering continued covering operations. This new covering device, however, moves new cover rolls to the work area by rotating the turntable 202, causing the new rotating wheel 5 to rotate slightly, saving time and effort and improving covering efficiency. It should be noted that when the mounting bracket 203 rotates, it moves the fixing sleeve 401, making it difficult for the polygonal slider 6 to insert into the slot. In this case, the fixing sleeve 401 near the polygonal slider 6 needs to be removed and installed at the previous rotating rod 3. This not only prevents the fixing sleeve 401 from interfering with the insertion of the polygonal slider 6 into the slot, and the spring B prevents the polygonal slider 6 from falling out of the slot during operation, but also prevents the previous rotating rod 3 from falling off.

[0025] Finally, during the covering process, the new rotating wheel 5 with the covering roll material installed can also be installed on the mounting frame 203. During installation, the fixing sleeve 401 needs to be removed. To remove it, first pull the limiting rod 403 to remove it from the fixing sleeve 401, thus releasing the fixing sleeve 401 from its limiting position. Since the fixing sleeve 401 is slidably connected to the rotating rod 3, the positioning sleeve can be removed from the rotating rod 3, thus releasing the rotating rod 3 from its limiting position. At this time, pull the rotating rod 3 and remove it from the rotating wheel 5 and the mounting frame 203. Then, the new rotating wheel... 5. Reinstall the rotating rod 3 and then reinstall the rotating rod 3 on the mounting bracket 203. After installation, install the fixing sleeve 401 on both ends of the rotating rod 3, and then insert the limiting rod 403 into the fixing sleeve 401 to limit the fixing sleeve 401 and prevent the rotating rod 3 from falling off. Spring A is used to prevent the limiting rod 403 from falling off the fixing sleeve 401. In summary, during the covering work, the rotating wheels 5 at other positions of the rotating rod 3 can also be replaced to prevent the covering material on the surface of several rotating wheels 5 from being completely used up, thereby making the covering work more efficient.
