Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically a heavy-duty telescopic tailings filling conveyor for soft ground. Background Technology

[0002] Tailings backfilling is an engineering technique for filling open-pit mines, underground goafs, and other artificial or natural pits with tailings slurry or solid waste generated during the mineral processing process. Its core function is to achieve the dual goals of large-scale disposal of mine solid waste and ecological restoration of goaf areas. This technology, through scientific spatial replacement and geological reconstruction, addresses the safety and environmental risks caused by surface tailings accumulation and is a key link in modern green mine closure. Traditional tailings backfilling has the following drawbacks: First, it suffers from significant efficiency defects in the material delivery method involving vehicle transport. Transport vehicles need to repeatedly unload at the pit edge to form a cone-shaped accumulation, subsequently relying on loaders for secondary pushing operations. This process not only leads to excessive material concentration at the edge, forming a stagnant zone, but also causes cross-interference in the work face due to frequent equipment back-and-forth movement, significantly reducing the overall material transfer efficiency due to the coordinated losses in multiple stages; Second, existing delivery methods... The lack of an effective central radial landfill mechanism means that the natural accumulation of materials under gravity results in a concave profile with high edges and a low center. This leads to insufficient utilization of the landfill space and difficulty in reaching the design elevation in the central area, requiring secondary paving through manual intervention, which increases engineering costs and affects the overall stability of the landfill. Thirdly, conventional rigid conveyors are prone to sinking when working on soft soil, and the fixed outriggers cannot compensate for uneven ground settlement in real time, causing the conveyor belt to deviate, which in turn leads to material spillage or even tearing of the conveyor belt edges and other derivative accidents, seriously affecting the continuity of operations and the service life of the equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a heavy-duty telescopic soft ground tailings filling conveyor to solve the problems mentioned in the background art.

The bottom of the fixed frame and the telescopic frame is fixedly connected to the position of the hydraulic jacking cylinder, and the output end of the hydraulic jacking cylinder is fixedly connected to the connecting seat.

[0008] As a further technical solution of the present invention, a counterweight base plate is provided at the bottom of the fixed frame, and a load-bearing plate at the corresponding position is fixedly connected to the counterweight base plate. A fixed bracket and a hydraulic station are fixedly connected to the counterweight base plate. A winding roller is rotatably connected to the fixed bracket, and a wire rope is fixedly connected to the winding roller. The other end of the wire rope is fixedly connected to one end of the telescopic frame.

[0009] As a further technical solution of the present invention, a first bearing seat is fixedly connected to the fixed frame, and a second support roller is rotatably connected to the first bearing seat, and the second support roller is in close contact with the conveyor belt.

[0010] As a further technical solution of the present invention, a second bearing seat is fixedly connected to the telescopic frame, and a third support roller is rotatably connected to the second bearing seat, and the third support roller is closely attached to the conveyor belt.

[0013] As a further technical solution of the present invention, limit rods are fixedly connected to the outer walls on both sides of the fixed frame.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention features a heavy-duty telescopic soft ground tailings filling conveyor. A V-shaped conveyor belt centrally transports the filling material to the filling pit. Compared to the traditional method of vehicle transfer and loader pushing, this eliminates efficiency losses caused by multi-stage coordination and effectively prevents material accumulation at the pit's edge. Furthermore, through its telescopic structural design, it can extend towards the center of the pit even when material accumulates at the edge, transporting the material towards the center for filling. This improves the utilization rate of the filling space and ensures that the central area reaches the design elevation, reducing engineering costs while guaranteeing the overall stability of the landfill. Simultaneously, for soft ground operations, a leveling support structure is designed. The base plate increases the contact area between the support structure and the ground, reducing the subsidence level. Combined with a multi-point independent hydraulic leveling system, a dynamic balance mechanism is formed, ensuring the equipment remains level on soft ground surfaces. This effectively prevents conveyor belt deviation, material spillage, and even conveyor belt edge tearing accidents, improving operational continuity and equipment lifespan.

[0019] Working Principle: When using this invention for tailings backfilling in soft ground, the entire device is first transported to the backfilling location. The telescopic conveyor consists of a fixed frame 1 and a telescopic frame 2. The fixed frame 1 serves as the main support structure for the entire device. The power roller 3, the first steering roller 17, the second steering roller 18, the third steering roller 19, and the fourth steering roller 20 provide support and guidance for the conveyor belt 10. The conveyor belt 10 is sequentially fitted onto the power roller 3, the first steering roller 17, the second steering roller 18, the third steering roller 19, and the fourth steering roller 20, forming a closed conveying loop. The conveyor belt 10 circulates under the drive of the power roller 3, realizing the material... For continuous material conveying, V-shaped supports 6 are fixedly connected to both the fixed frame 1 and the telescopic frame 2 by fixing bolts 7. Inclined support rollers 8 and first support rollers 9 are rotatably connected to the V-shaped supports 6. The conveyor belt 10 is tightly attached to these support rollers, forming a V-shaped conveying surface, which helps to concentrate and stabilize the material during the conveying process. The first motor 4 drives the power roller 3 through the first reducer 5, thereby driving the conveyor belt 10 to move and convey the material. During the conveying process, the conveyor belt 10 is supported by the second support rollers 13 and the third support rollers 14 on the first bearing seat 11 and the second bearing seat 12, ensuring the smooth operation of the conveyor belt 10. During use, the device... The counterweight base plate 21 and the load-bearing plate 31 contact the soft ground surface, increasing the contact area between the equipment and the ground, reducing the sinking level, and improving the stability of the equipment when working on soft ground. By independently controlling the extension and retraction of each hydraulic jacking cylinder 32, the hydraulic jacking cylinder 32 lifts the connecting seat 33, adjusting the level of the equipment on the soft ground surface, preventing the equipment from sinking and the conveyor belt 10 from deviating. When the edge of the pit is filled, the hydraulic push cylinder 16 pushes the telescopic frame 2 forward and limits its extension and retraction through the limit rod 15 to prevent it from exceeding the design stroke. The material is directly delivered to the center of the pit by the extended conveyor belt 10. During use, the fixed frame 1 is secured by the counterweight base plate. Plate 21 increases the center of gravity at the rear of the equipment. A hydraulic station 22 and a fixed bracket 23 are installed on the counterweight base plate 21. The hydraulic station 22 is used to drive the hydraulic push cylinder 16 and the hydraulic top cylinder 32 to work, and is connected to the wire rope 30 through the winding roller 24. The wire rope 30 passes through the second pulley 29 and the first pulley 28 on the inclined support 27 in sequence to pull the front end of the telescopic frame 2. According to the telescopic stroke of the telescopic frame 2, the second motor 25 drives the winding roller 24 to rotate through the second reducer 26 to realize the winding and unwinding of the wire rope 30. By adjusting the center of gravity and the rope traction, the overall operation of the device is kept stable, preventing the device from tilting forward and falling into the pit and the telescopic frame 2 from becoming unbalanced.
