Description

Technical Field

[0001] This invention belongs to the field of sound insulation equipment technology, specifically a sound insulation device for a scraper conveyor in a coal preparation plant and its usage method. Background Technology

[0002] Scraper conveyors are transport machinery used in coal mine working faces. They are mainly used for transporting coal in coal mining faces and mining roadways, and can also be used in coal roadways and semi-coal-rock roadway excavation faces. They can transport upwards and downwards. Scraper conveyors have advantages such as transport capacity not being affected by the size and moisture of the load, small body height for easy loading, convenient body length adjustment, and a robust body that can be used in blasting and coal loading working faces. Therefore, they are widely used in coal mines in many towns.

[0003] In existing technologies, the friction between material particles and the internal structure of existing scraper conveyors easily generates significant noise during actual use. Prolonged exposure to such noise can negatively impact the health of construction workers, consequently affecting construction efficiency and resulting in suboptimal performance. Furthermore, existing scraper conveyor sound insulation devices have a fixed overall structure and are often directly connected to the existing conveyor, failing to effectively prevent noise generated by vibration during operation. This direct connection also hinders installation, maintenance, and replacement, further complicating the maintenance and installation process. Consequently, the actual effectiveness of existing scraper conveyor sound insulation devices remains unsatisfactory. Summary of the Invention

[0004] The purpose of this invention is to provide a sound insulation device for scraper conveyors in coal preparation plants and its usage method, which can be conveniently adapted to the actual structure of existing scraper conveyors, thereby meeting the needs of existing scraper conveyors of different lengths and specifications, and can be easily installed and set up, effectively avoiding the impact of scraper conveyor vibration on sound insulation.

[0005] The technical solution adopted in this invention is as follows: A sound insulation device for a scraper conveyor in a coal preparation plant and its usage method, comprising a first functional mechanism, the first functional mechanism including a base and a moving component, wherein adjustment grooves are provided on both sides of the inner surface of the base, the four adjustment grooves are divided into two groups, and a moving plate is slidably inserted between the two adjustment grooves in each group, a connecting rod is rotatably connected between the two sides of the base and the inner surface of the base, and a first bevel gear is sleeved on the outer surface of the connecting rod near the two side edges, a set of support blocks is fixedly connected to the top of the base near the two side edges, two support blocks are provided in each group, and a support roller is rotatably connected between the two support blocks in each group and the outer surface of the two support blocks, a rotating worm gear is sleeved on the outer surface of one of the support rollers near one end edge, an adjustment ring is provided between the tops of the two support rollers, a connecting frame is fixedly connected to the inner surface of the adjustment ring, a sound insulation cotton frame is fixedly connected inside the connecting frame, a first top plate is inserted into the top of the connecting frame, a first sound insulation cotton sheet is fixedly connected to the bottom of the first top plate, and the moving component is disposed on the base; and

[0006] The second functional mechanism includes an extension frame, which is fixedly connected to the outer surface of one side of the connecting frame by bolts. A microporous sound-absorbing frame is fixedly connected inside the extension frame. A side frame is fixedly connected to the outer surface of one side of the extension frame by bolts, and a microporous sound-absorbing frame is also fixedly connected inside the side frame.

[0007] Each of the movable plates has two rotating blocks rotatably connected to its bottom, and each rotating block has a movable wheel rotatably connected to one side of its outer surface.

[0008] The base has a linkage frame fixedly connected to one side of its outer surface, and a rotating worm gear is rotatably connected to the top of the linkage frame. The rotating worm gear meshes with a rotating worm wheel, and a first linkage gear is sleeved at the bottom end of the rotating worm gear.

[0009] The bottom of the linkage frame is rotatably connected to a rotating rod, and a second linkage gear is sleeved on the outer surface of the rotating rod. The second linkage gear meshes with the first linkage gear, and a third bevel gear is sleeved on the outer surface of the rotating rod.

[0010] A drive motor is fixedly connected to one side of the outer surface of the base, and a fourth bevel gear is sleeved on the output end of the drive motor. The fourth bevel gear meshes with the third bevel gear.

[0011] The movable component includes two adjusting threaded rods, which are rotatably connected to the outer surfaces of the base on both sides. Each adjusting threaded rod has a push tube threadedly connected to its outer surface. Each push tube has a connecting strip fixedly connected to its top end. The top of each connecting strip is fixedly connected to the bottom of the corresponding movable plate. Each adjusting threaded rod has an adjusting worm gear sleeved on its outer surface.

[0012] The base has two outer surfaces on both sides rotatably connected to adjusting worm gears. Each adjusting worm gear meshes with a corresponding adjusting worm wheel. One end of each adjusting worm gear is fixedly connected to an extension rod. The outer surface of each extension rod is fitted with a second bevel gear. Each second bevel gear meshes with a corresponding first bevel gear.

[0013] The extension frame is provided with two second top plates, and each second top plate is fixedly connected to a second sound insulation cotton sheet at its bottom.

[0014] The side frame is fitted with a third top plate, and the bottom of the third top plate is fixedly connected with a third sound insulation cotton sheet.

[0015] A method for using a sound insulation device for a scraper conveyor in a coal preparation plant includes the following steps:

[0016] S1. Installation and Adjustment: The first functional mechanism and extension frame can be added or removed according to the actual use. During the actual installation process, the extension frame can be connected and fixed on both sides of the connecting frame by existing bolts. Then, the drive motor is started by controlling the start of the drive motor, which drives the second linkage gear to rotate through the fourth bevel gear, the third bevel gear and the rotating rod. The second linkage gear, in conjunction with the first linkage gear, drives the rotating worm to rotate. The rotating worm, in conjunction with the rotating worm wheel, drives the corresponding support roller to rotate. The rotating support roller can rotate to adjust the angle of the adjustment frame, so that the top opening of the connecting frame and the extension frame faces the existing scraper machine. With the support of the moving wheels, the position of the base can be easily moved and adjusted, so that the existing scraper machine can pass through the inside of the connecting frame and the extension frame.

[0017] S2. Function Adjustment: By controlling the start of the drive motor, the operating angles of the connecting frame and extension frame can be effectively adjusted, restoring the openings of the connecting frame and extension frame to their top positions. Then, by rotating the linkage rod, the linkage rod can drive the corresponding adjusting worm gear to rotate through the first bevel gear, the second bevel gear, and the extension rod. This allows the adjusting worm gear, in conjunction with the adjusting worm wheel, to drive the corresponding adjusting threaded rod to rotate. The rotating adjusting threaded rod can adjust the operating height of the push tube, allowing the push tube to move and adjust the operating height of the moving plate in conjunction with the linkage bar. This allows the bottom of the base to gradually conform to the ground, ensuring the base is stably placed in the designated operating position. At this time, the side frame blocks the two ends of the existing scraper machine, preventing the equipment from directly contacting the existing scraper machine. Simultaneously, the sound insulation cotton frame, the first sound insulation cotton sheet, the second sound insulation sheet, the third sound insulation cotton sheet, and the microporous sound-absorbing frame can absorb and reduce noise.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, the first functional mechanism and extension frame can be added or removed according to actual usage, thereby enabling the equipment to meet the needs of existing scraper machines of different lengths. During actual installation, the extension frame can be connected and fixedly connected to both sides of the connecting frame using existing bolts. The drive motor is then started, which in turn drives the second linkage gear to rotate via the fourth bevel gear, the third bevel gear, and the rotating rod. This second linkage gear, in conjunction with the first linkage gear, effectively drives the rotating worm gear to rotate. The rotating worm gear, in conjunction with the rotating worm wheel, effectively drives the corresponding support roller to rotate. This allows the rotating support roller to effectively adjust the angle of the adjustment frame, ensuring that the top openings of the connecting frame and extension frame face the existing scraper machine. With the support of the moving wheels, the base's position can be easily adjusted, allowing the existing scraper machine to effectively penetrate the connecting frame and extension frame. By starting the drive motor again, the angle of the connecting frame and extension frame can be effectively adjusted, restoring the openings of the connecting frame and extension frame to their top positions. Then, by rotating the connecting... The moving rod, in turn, enables the connecting rod to effectively drive the corresponding adjusting worm gear to rotate via the first bevel gear, the second bevel gear, and the extension rod. This, in turn, allows the adjusting worm gear, in conjunction with the adjusting worm wheel, to effectively drive the corresponding adjusting threaded rod to rotate. The rotating adjusting threaded rod effectively adjusts the height of the push tube, which in turn, in conjunction with the connecting strip, effectively moves the adjusting plate to adjust its height. This allows the bottom of the base to gradually conform to the ground, ensuring the base is stably placed in the designated location. At this point, the side frame effectively shields both ends of the existing scraper machine, preventing direct contact between the equipment and the existing scraper machine. This effectively avoids noise from the existing scraper machine's vibration affecting the equipment's functionality. Simultaneously, the sound insulation cotton frame, the first sound insulation cotton sheet, the second sound insulation surface sheet, the third sound insulation cotton sheet, and the microporous sound-absorbing frame effectively absorb and reduce noise, ensuring efficient construction work and enabling the equipment to perform its intended functions efficiently. Furthermore, the first, second, and third top plates facilitate convenient maintenance and adjustment of the existing scraper machine, further ensuring the equipment's efficient operation.

[0034] Step 1, Installation and Adjustment: Add or remove the first functional mechanism 1 and extension frame 201 according to actual usage to enable the equipment to meet the needs of existing scraper machines of different lengths. During the actual installation process, the extension frame 201 can be connected and fixedly connected to both sides of the connecting frame 116 using existing bolts.
