Description

Technical Field

[0001] This utility model relates to the field of coal bunker cleaning structure technology, specifically a rotary structure cleaning machine for cleaning raw coal bunkers in power plants. Background Technology

[0002] As the core facility for storing raw coal in a coal-fired power generation system, the inner wall of the raw coal bunker is prone to forming slabs and coal clumps due to factors such as fluctuations in the moisture content of the raw coal, long-term accumulation, and uneven friction of the bunker wall. If not cleaned in time, it can lead to reduced bunker capacity, blockage of material discharge, and even safety hazards caused by uneven stress on the bunker wall. Therefore, efficient bunker cleaning is a key link in ensuring the stable operation of the power generation system.

[0003] Currently, most existing cleaning machines adopt a single fixed-direction cleaning structure or rely solely on the rotation of the cleaning head itself. This results in the cleaning head only being able to cover a local area of ​​the bin wall, easily creating blind spots in areas such as bin corners and the junction between the top and bottom, and making it difficult to reach into corner areas, thus resulting in an inefficient cleaning effect inside the raw coal bin.

[0004] Therefore, this utility model proposes a rotary structure cleaning machine for cleaning raw coal bunkers in power plants to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rotary structure cleaning machine for cleaning raw coal bunkers in power plants, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary structure cleaning machine for cleaning raw coal bunkers in power plants, comprising a support frame and a mounting rod. Support columns are fixedly installed around the top of the support frame, a support plate is fixedly installed on the top of the support columns, a servo motor is fixedly installed at the center of the top of the support plate, and a mounting rod is rotatably installed at the bottom of the servo motor.

[0007] One end of the hydraulic oil pipe is fixedly connected to a hydraulic connector, and the other end of the hydraulic connector is fixedly connected to a hydraulic motor. A rotating disc is rotatably connected to the bottom of the hydraulic motor. Fastening nuts can be detachably installed around the bottom of the rotating disc, and flexible cleaning heads can be detachably installed around the surface of the rotating disc.

[0008] A mounting plate is fixedly installed on the top of the servo motor, and a take-up roller is rotatably mounted on the top of the mounting plate. A hydraulic oil pipe is rotatably mounted on the surface of the take-up roller.

[0009] A telescopic rod is telescopically sleeved on one side of the mounting rod surface, and a sleeve block is fixedly sleeved on the surface of the telescopic rod. A guide roller is rotatably installed at the bottom of the sleeve block.

[0010] Preferably, the mounting rod is L-shaped and is fixedly installed at the bottom of the servo motor. The servo motor drives the mounting rod to rotate and adjust at the center position at the top of the bracket.

[0011] Preferably, the hydraulic hose is retracted and adjusted at the top of the support via a take-up roller.

[0012] Preferably, the hydraulic hose is movably engaged at the intersection of the mounting rod, telescopic rod, and guide roller surfaces.

[0013] Preferably, the rotating disc rotates on one side of the support surface via hydraulic oil pipes and a hydraulic motor, and simultaneously drives the flexible cleaning head to rotate and adjust.

[0014] Preferably, the flexible cleaning head can be detachably mounted around the surface of the rotating disc by means of a fastening nut.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a rotary cleaning machine for cleaning raw coal bunkers in power plants. Driven by a servo motor on the top of a support plate, an L-shaped mounting rod rotates the cleaning components around the center of the bunker. This, combined with a hydraulically driven rotating disc and surrounding flexible cleaning heads, enables high-speed rotation, improving the cleaning efficiency of coal accumulation on the inner walls and corners of the bunker and avoiding blind spots. The telescopic rod, with its telescopic sleeve on the mounting rod surface, allows for flexible adjustment of the cleaning radius to accommodate bunkers of different diameters. Guide rollers limit and guide the hydraulic hoses, and the retraction rollers adjust the hoses to ensure orderly arrangement during the rotation of the mounting rod and the extension of the telescopic rod, preventing entanglement and ensuring stable hydraulic power transmission. The flexible cleaning heads are detachable via fastening nuts, facilitating the replacement of cleaning heads of different materials based on the hardness of the accumulated coal, reducing wear on the bunker walls and lowering the cost of replacing vulnerable parts.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1 Please see Figure 1 and Figure 2 A rotary structure cleaning machine for cleaning raw coal bunkers in power plants includes a support frame 100 and a mounting rod 200. Support columns 101 are fixedly installed around the top of the support frame 100. A support plate 102 is fixedly installed on the top of the support columns 101. A servo motor 103 is fixedly installed at the center of the top of the support plate 102. The mounting rod 200 is rotatably installed at the bottom of the servo motor 103.

[0020] A fixing plate 104 is fixedly installed on the top of the servo motor 103, and a take-up roller 105 is rotatably installed on the top of the fixing plate 104. A hydraulic oil pipe 106 is rotatably installed on the surface of the take-up roller 105. One end of the hydraulic oil pipe 106 is fixedly connected to the hydraulic connector 111, and one end of the hydraulic connector 111 is fixedly connected to the hydraulic motor 107. The bottom of the hydraulic motor 107 is rotatably connected to the rotating disc 108. The bottom of the rotating disc 108 is detachably fitted with fastening nuts 109, and the surface of the rotating disc 108 is detachably fitted with flexible cleaning heads 110.

[0021] In use, the bracket 100 provides support for the support plate 102 through the support columns 101 around its top perimeter. After the servo motor 103 at the center of the support plate 102 starts, it drives the mounting rod 200 at the bottom to rotate around the center of the raw coal bunker, thereby driving the cleaning component at the end of the mounting rod 200 to achieve wide-area coverage. The winding roller 105 on the top fixing plate 104 of the servo motor 103 is used to store and release the hydraulic oil pipe 106, ensuring that the hydraulic oil pipe 106 can be flexibly retracted and extended with the rotation of the mounting rod 200, avoiding entanglement and jamming. One end of the hydraulic oil pipe 106 is connected to a hydraulic power source to deliver hydraulic oil to… The hydraulic motor 107 at the end of the mounting rod 200 provides power to drive the rotating disk 108 to rotate at high speed. The flexible cleaning head 110, which is fixed around the surface of the rotating disk 108 by the fastening nut 109, rotates synchronously with the disk. Finally, under the dual action of the rotation of the mounting rod 200 driven by the servo motor 103 and the rotation of the flexible cleaning head 110 driven by the hydraulic motor 107, the flexible cleaning head 110 performs all-round and efficient cleaning of the coal accumulation on the inner wall and corners of the raw coal bunker. The take-up roller 105 simultaneously adjusts the length of the hydraulic oil pipe 106 to ensure stable power transmission and coordinated operation of the cleaning action.

[0022] It should be noted that: Reference Figure 2 One end of the hydraulic oil pipe 106 is connected to an external oil conveying device, and the other end is connected to a hydraulic motor 107 through a hydraulic connector 111. The middle part of the hydraulic oil pipe 106 is wound around the take-up roller 105. The extension and retraction length of the hydraulic oil pipe 106 can be adjusted by rotating the take-up roller 105.

[0023] Example 2 Based on Example 1, please refer to Figure 3 A telescopic rod 201 is telescopically sleeved on one side of the surface of the mounting rod 200. A sleeve block 202 is fixedly sleeved on the surface of the telescopic rod 201. A guide roller 203 is rotatably mounted on the bottom of the sleeve block 202. The mounting rod 200 is L-shaped and is fixedly mounted on the bottom of the servo motor 103. The servo motor 103 drives the mounting rod 200 to rotate and adjust at the center position of the top of the bracket 100.

[0024] In use, the telescopic rod 201, which is telescopically sleeved on the surface of the mounting rod 200, can flexibly adjust its extension length according to the inner diameter of the raw coal bunker, thereby changing the working radius of the end cleaning component and adapting to the cleaning needs of raw coal bunkers of different specifications. The guide roller 203 at the bottom of the sleeve block 202 on the surface of the telescopic rod 201 plays a limiting and guiding role for the hydraulic oil pipe 106 released by the winding roller 105, ensuring that the hydraulic oil pipe 106 can move along the surface of the mounting rod 200 and the telescopic rod 201 when the mounting rod 200 rotates and the telescopic rod 201 extends. The hydraulic hose 106 is retracted sequentially to avoid tangling and jamming. At the same time, the take-up roller 105 moves in sync with the installation rod 200 to retract and extend the hydraulic oil pipe 106, stably delivering hydraulic oil to the hydraulic motor 107, which drives the rotating disc 108 and the flexible cleaning head 110 to rotate at high speed. Finally, with the synergistic effect of the L-shaped installation rod 200 rotating to achieve large-area coverage, the telescopic rod 201 extending and retracting to adapt to different bin diameters, and the guide roller 203 ensuring smooth transmission of oil pipes, the flexible cleaning head 110 completes the efficient cleaning of coal accumulation on the inner wall and corners of the raw coal bin by rotation.

[0025] Example 3 Based on Example 2, please refer to Figure 4 The hydraulic oil pipe 106 is retracted and adjusted at the top of the bracket 100 via the take-up roller 105. The hydraulic oil pipe 106 is movably engaged at the intersection of the surfaces of the mounting rod 200, the telescopic rod 201, and the guide roller 203. The rotating disc 108 rotates on one side of the surface of the bracket 100 via the hydraulic oil pipe 106 and the hydraulic motor 107, and simultaneously drives the flexible cleaning head 110 to rotate and adjust. The flexible cleaning head 110 can be detachably installed around the surface of the rotating disc 108 via the fastening nut 109.

[0026] In use, the guide roller 203 at the bottom of the upper sleeve block 202 of the telescopic rod 201 intersects with the mounting rod 200 and the surface of the telescopic rod 201 to form an oil pipe guide path. The hydraulic oil pipe 106 is movably engaged in this path. At the same time, the winding roller 105 on the support plate 102 achieves synchronous winding and unwinding adjustment. The hydraulic oil pipe 106 stably transmits hydraulic power to the hydraulic motor 107 at the end of the mounting rod 200, driving the rotating disc 108 to rotate at high speed. The flexible cleaning head 110, which can be detachably installed around the surface of the rotating disc 108 through the fastening nut 109, rotates synchronously with it. This also facilitates the replacement of different types of cleaning equipment to deal with the cleaning of different types of coal bunkers.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
