Description

Technical Field

[0001] This invention relates to the field of trestle cleaning technology, and in particular to a coal conveying trestle cleaning device and its usage method. Background Technology

[0002] Coal conveyor bridges are generally made of steel and are elevated, some enclosed and some not, with conveyors installed inside. To reduce dust pollution, the bridges need to be cleaned during use. Cleaning includes the conveyor belts and the bridge's internal floor. Typically, two sets of cleaning equipment are needed: one for the conveyor belts and the other for the floor. This presents problems such as large footprint, high investment costs, and inconvenient installation, hindering large-scale construction. Furthermore, due to the high dust levels inside the bridge, conventional washing methods using nozzles and pipes are prone to dust accumulation at the pipes and external outlets, potentially causing blockages and interrupting the cleaning equipment's flow, thus affecting the cleaning process. Summary of the Invention

[0003] This invention proposes a coal conveyor bridge cleaning device and its usage method, which solves the problem that current coal conveyor bridge cleaning equipment cannot clean both the conveyor belt and the bridge at the same time, resulting in a large footprint and high investment.

[0004] The technical solution of this invention is implemented as follows:

[0005] A coal conveyor bridge cleaning device includes a main pipeline, secondary pipelines symmetrically connected to both sides of the main pipeline, a number of auxiliary pipelines spaced apart on one side of the secondary pipelines, a hollow tube inside the secondary pipeline, a blade at one end of the hollow tube and a rotatably connected end to the last auxiliary pipeline, a number of washing discs sliding on the hollow tube, a number of limiting devices cooperating with the washing discs on the hollow tube, the limiting devices being located at the intervals between two adjacent pipelines, a number of water holes on the hollow tube, the positions of the water holes corresponding one-to-one with the secondary pipelines and the number of auxiliary pipelines, a number of water inlets on the washing discs, the water inlets communicating with their internal flow channels, and cleaning components slidingly arranged within the flow channels.

[0006] The main pipe is a reducing pipe, with a smaller diameter at the end closest to the secondary pipe. A guide plate is installed inside the secondary pipe, located directly below the main pipe. This guide plate enhances the impact force and pressure of the water flow in the main pipe, maintains the water pressure inside the pipe, and thus ensures the stable operation of the overall structure.

[0007] The cleaning components include a top plate that slides within the flow channel, a cleaning strip on the top plate, and interconnected water spray channels on the top plate and the cleaning strip. Through the reciprocating washing disc and the retractable cleaning strip, the equipment's pipeline structure can be cleaned of dust at all times, avoiding pipeline blockage and ensuring the cleaning of the trestle.

[0008] The cleaning strip has a brush at the end, which improves the cleaning ability of the parts and makes them cleaner.

[0009] The limiting device includes a recessed hole on the outer wall of the hollow tube, a spring-driven limiting ball inside the recessed hole, and a limiting hole on the inner hole of the washing tray. The diameter of the limiting hole of each washing tray is different. The limiting hole of the washing tray placed at the front end has the smallest diameter, and the limiting hole of the washing tray placed at the rear end has the largest diameter. The diameter of each set of limiting balls is the same as the diameter of the corresponding limiting hole.

[0010] The flow channel runs through the outer wall of the washing tray, and a placement hole is provided at the end of the flow channel. A cover plate is hinged in the placement hole by a torsion spring. The movable end of the cover plate is equipped with a rotating shaft, which can automatically retract the cleaning strip and facilitate the washing tray reset.

[0011] The thickness of the wash plate is the same as the distance between the wash plates.

[0012] The hollow tube has a first limiting block at the end near the blade for limiting the washing plate, which limits the washing plate and prevents it from colliding with the blade during reset.

[0013] Both the secondary and secondary pipelines are equipped with movable feet at their lower ends to facilitate positioning and installation.

[0014] One method of using a coal conveyor bridge cleaning device includes the following steps:

[0015] S1. Arrange and fix the secondary pipe and the primary pipe concentrically and evenly, and then insert the hollow tube from back to front through the primary pipe and into the secondary pipe.

[0016] S2, inject high-pressure water into the main pipe, and the water flow pushes the washing disc to get stuck in the gap between two adjacent pipes in turn;

[0017] S3 continuously injects high-pressure water flow, the hollow tube rotates, driving the suction cup to rotate, and at the same time ejects the cleaning components to clean the bottom of the conveyor belt and the surface of the trestle.

[0018] Beneficial effects

[0019] This invention features a hollow pipe installed between the secondary and primary pipes, with a sliding and rotating washing disc mounted on the hollow pipe. A sliding cleaning component is installed within the washing disc, which can extend or retract as needed and according to location. This allows for simultaneous cleaning of the lower end of the conveyor belt and the bottom plate of the trestle, while minimizing the size of the washing disc and reducing floor space. Furthermore, the entire structure is hydraulically driven, reducing energy consumption. The modular design facilitates installation and use. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-5As shown, a coal conveyor bridge cleaning device includes a main pipeline 1, with secondary pipelines 2 symmetrically connected to both sides of the main pipeline 1. Several auxiliary pipelines 3 are spaced apart on one side of each secondary pipeline 2. A hollow tube 6 is installed inside each secondary pipeline 2. One end of the hollow tube 6 has a paddle, and the other end is rotatably connected to the last auxiliary pipeline 3. The last auxiliary pipeline 3 has a reset hole 5. Several washing discs 9 are slidably mounted on the hollow tube 6. Several limiting devices that cooperate with the washing discs 9 are installed on the hollow tube 6, located at intervals 8 between adjacent pipelines. The thickness of the washing discs 9 is the same as the distance between the intervals 8. Several water holes 4 are provided on the hollow tube 6, with the positions of the water holes 4 corresponding one-to-one with the secondary pipeline 2 and the several auxiliary pipelines 3. Each secondary pipe 2 and each secondary pipe 3 is provided with a set of water holes 4, and the water holes 4 are located at the end near the water inlet. The washing plate 9 is provided with several water inlets 16, which face the side near the main pipe 1. The water inlets 16 are connected to the flow channel 17 inside. The flow channel 17 is a variable diameter channel. A cleaning component is slidably provided in the flow channel 17. The cleaning component includes a top plate 18 slidably provided in the flow channel 17. A second limiting block 21 for the top plate 18 is provided in the flow channel 17. A cleaning rubber strip 19 is provided on the top plate 18. The cleaning rubber strip 19 is a rubber strip. A water spray passage 20 is provided on the top plate 18 and the cleaning rubber strip 19. A brush 22 is provided at the end of the cleaning rubber strip 19.

[0029] The reset hole 5 is equipped with a matching push rod, which can push the washing plate 9 to reset when the cleaning strip 19 retracts and resets.

[0030] The limiting device includes a recess 13 on the outer wall of the hollow tube 6, a limiting ball 15 driven by a spring 14 inside the recess 13, and a limiting hole 26 on the inner hole of the washing plate 9. The diameter of the limiting hole 26 of each washing plate 9 is different. The limiting hole 26 of the washing plate 9 placed at the front end has the smallest diameter, and the limiting hole 26 of the washing plate 9 placed at the rear end has the largest diameter. The diameter of each set of limiting balls 15 is the same as the size of the corresponding limiting hole 26. Therefore, the diameter of the limiting balls 15 between the frontmost intervals 8 is the smallest. In this embodiment, the front end refers to the end close to the main pipe 1, and the rear end refers to the end close to the last branch pipe 3.

[0031] The working process of this embodiment is as follows: First, the secondary pipe 2, which is connected to the main pipe 1, is placed in the middle. Then, several secondary pipes 3 are installed on both sides at intervals. The secondary pipes 2 and secondary pipes 3 are placed concentrically. Then, the tail of the hollow tube 6 with several washing plates 9 is rotatably connected to the inner wall of the last secondary pipe 3. The number of washing plates 9 is the same as the number of secondary pipes 3. Then, high-pressure water is injected into the main pipe 1. When the water flows into the secondary pipe 2, the hollow tube 6 is rotated by the paddle, and at the same time, the water pressure pushes the washing plates 9 forward. Through experiments, water holes 4 with limited apertures are set. When the water flows through the water holes 4, the loss of water flow and water pressure is small, and the lateral water flow can flush... The washing plate 9 is pushed and pushed. Since the limiting hole 26 of the rear washing plate 9 is the largest and the diameter of the limiting ball 15 of the front is the smallest, the rear washing plate 9 is pushed into the pipe 3, while the front washing plate 9 is engaged with the limiting ball 15. The water pressure is determined by experimental adjustment. When the washing plate 9 is engaged with the limiting ball 15, it is necessary to prevent the washing plate 9 from breaking through the limitation of the limiting ball 15. The washing plate 9 blocks the interval 8, so that the secondary pipe 2 and the first pipe 3 are relatively sealed. At the same time, the water flows into the first pipe 3 through the water hole 4. Then, the washing plate 9 is pushed to move. The above steps are repeated until all the washing plates 9 move to the limiting device at the interval 8.

[0032] When the hollow tube 6 rotates, it drives the washing disc 9 to rotate. At the same time, high-pressure water flows into the flow channel 17 through the inlet 16. The pressure lifts the top plate 18 and pushes out the cleaning strip 19. Simultaneously, water is sprayed through the spray channel 20. When the washing disc 9 rotates, it can clean the lower end of the conveyor belt and the bottom plate of the trestle. Due to gravity, when the washing disc 9 rotates, the upper cleaning strip 19 extends a shorter length, while the lower cleaning strip 19 extends a longer length. This allows for a proper reduction in the length of the cleaning strip 19 while ensuring that the bottom plate of the trestle and the conveyor belt can be cleaned, further reducing equipment investment.

[0033] Example 2

[0034] Preferably, the main pipe 1 is a reducing pipe with a smaller diameter at the end near the secondary pipe 2. A guide plate 11 is provided inside the secondary pipe 2, which is located directly below the main pipe 1. The guide plate 11 can enhance the impact force and pressure of the water flow in the main pipe 1, maintain the water pressure inside the pipe, and thus ensure the stable operation of the overall structure. The hollow pipe 6 is provided with a first limiting block 10 for limiting the washing plate 9 at the end near the blade, which limits the washing plate and prevents it from colliding with the blade during reset.

[0035] The flow channel 17 penetrates the outer wall of the washing tray 9, and the end of the flow channel 17 is provided with a placement hole 23. A cover plate 25 is hinged in the placement hole 23 by a torsion spring 24. The movable end of the cover plate 25 is provided with a rotating shaft 12. As the water pressure in the pipe decreases, the rotation speed and centrifugal force of the washing tray 9 become smaller and smaller. Due to the gravity being greater than the centrifugal force and the impact force of the water, the cleaning rubber strip 19 at the upper end of the washing tray 9 slides down and retracts into the flow channel 17 in sequence. The rotating shaft 12 can reduce the friction between the cover plate 25 and the cleaning rubber strip 19. The cover plate 25 automatically resets. Without the impact force of the water, the cleaning rubber strip 19 cannot push open the cover plate 25 and can automatically retract the cleaning rubber strip 19, making it easy for the washing tray 9 to reset.

[0036] Both the secondary pipe 2 and the main pipe 3 are equipped with movable feet 7 at their lower ends. The movable feet 7 can be set on a linear slide rail and connected to the main pipe 1 using a longer telescopic pipe, which can drive the overall structure to move and expand the cleaning range of a single set.

[0037] A method for using a coal conveyor bridge cleaning device includes the following steps:

[0038] S1, arrange and fix the secondary pipe 2 and the main pipe 3 concentrically and evenly spaced in sequence, and then insert the hollow pipe 6 from back to front through the main pipe 3 and into the secondary pipe 2.

[0039] S2, inject high-pressure water into the main pipe 1, and the water flow pushes the washing plate 9 to get stuck in the interval 8 between two adjacent pipes in turn;

[0040] S3, continuous high-pressure water flow, hollow tube 6 rotates, driving suction cup 9 to rotate, and at the same time pushing out the cleaning component to clean the bottom of the conveyor belt and the surface of the trestle.

[0041] The other structures in this embodiment are the same as in Embodiment 1.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
