Description

Technical Field

[0001] This invention relates to the field of mining construction technology, and in particular to a method for the overall movement and relocation of a mining spoil disposal machine. Background Technology

[0002] The dumping machine is a core piece of equipment in continuous mining operations, and its relocation efficiency directly impacts mine production. As the working face advances, the dumping machine needs to be relocated periodically to adapt to new dumping operation requirements. The traditional relocation method involves completely disassembling the dumping machine and unloading trucks into multiple components, transporting each component to the new site, and then reassembling them. This method has significant drawbacks: extremely long construction periods (usually several months), labor-intensive operations, high machinery operating costs, and the equipment is easily damaged during disassembly and reassembly, with complex commissioning work after reinstallation. More importantly, dumping operations are completely interrupted during relocation, forcing the mine to adopt more expensive methods such as truck transport to maintain production, resulting in huge direct economic losses. Summary of the Invention

[0003] To overcome these shortcomings, the technical problem to be solved by this invention is: how to improve the problem of long operation cycle and high cost of relocation of soil dumping machines.

[0004] The technical solution adopted by this invention to solve its technical problem is: The construction method for the overall movement and relocation of a mine spoil heap includes the following steps. S1: Relocation route planning and foundation treatment; S2: Determine the safe distance and elevation difference between the tracked walking device of the dumper and the unloading vehicle track, as well as the safe distance between the tracked device and the slope, and delineate the tracked walking path range; S3: Track system laying; S4: Control the soil dumper and unloading truck as a whole to travel along the path designed in S1 until they reach the new installation location.

[0005] Furthermore, in step S1, the specific process of relocation path planning includes: planning a curved temporary path for the overall movement of the dumping machine and the unloading vehicle; the curved temporary path consists of at least two tangent arcs, and the two ends of the curved temporary path are respectively tangent to the original dumping conveyor belt system and the new dumping mobile conveyor belt system.

[0006] Furthermore, in step S1, the foundation treatment method includes leveling, compacting, and reinforcing the foundation within the path range.

[0007] Furthermore, in step S2, the ground height difference between the unloading vehicle and the support vehicle and the tracked walking device must be less than 700mm.

[0008] Furthermore, the centerline of the tracked walking device is at least 20m away from the centerline of the unloading vehicle and the support vehicle's track.

[0009] Furthermore, the average ground pressure at the site where the spoiler is installed is greater than or equal to 110 kPa.

[0010] Furthermore, the outermost track device of the track movement device must be at least 20m away from the slope.

[0011] Furthermore, step S3 includes laying the tracks for the unloading vehicle and the support vehicle, and leveling the road for the tracked walking device; along the planned curved path, after cutting off the power and removing the conveyor belt, an excavator or similar mechanical equipment is used to slowly drag the entire track system, including the track, sleepers, and roller frames, to the designed position of the temporary path, and then correct and fix it.

[0012] Furthermore, the movement of the dumper is mainly operated by the driver in the cab, using a variable frequency motor to drive the tracked walking device, the unloading vehicle, and the support vehicle.

[0013] Furthermore, the overall curved movement of the spoiler begins with the first step of the tracked walking device. When the receiving arm approaches the tail of the receiving arm support wheel, the tracked walking device immediately stops. The second step involves the unloading vehicle and support vehicle moving; when the receiving arm approaches the head of the receiving arm support wheel, the unloading vehicle and support vehicle moving devices immediately stop. These two steps are repeated to achieve the overall curved movement of the spoiler.

[0014] The beneficial effects of this invention are: A temporary travel path was designed between the original and new mobile conveyor belt systems for dumping. The temporary path was laid by protectively relocating the original conveyor belt track system. Simultaneously, the road in the dumper's track area was leveled and compacted. Finally, by controlling the alternating and synchronous operation of the dumper's track and the unloading / support vehicle's track travel devices, the dumper and unloading vehicle, weighing over a thousand tons, were driven to travel along a curved path. This approach avoids cumbersome disassembly and reassembly, significantly shortens the relocation period, reduces construction costs, and minimizes safety risks, resulting in substantial economic and social benefits. It provides a safe and efficient solution for the rapid relocation of large-scale continuous transport equipment in mines. Attached Figure Description

[0015] Figure 1 This is a flowchart of the method of the present invention; Figure 2 This is a schematic diagram of the relocation path of the present invention; The diagram is marked as follows: 1 - original soil dumping conveyor belt system, 2 - newly built soil dumping mobile conveyor belt system, 3 - temporary curved path. Detailed Implementation

[0016] The invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown in the embodiment of this application, a method for constructing a mine spoil disposal machine that moves and relocates as a whole is proposed, including the following steps: S1: Relocation Path Planning and Foundation Treatment; Based on the site topography and new site location, accurately plan the curved relocation path of the dumper from the current location to the new location. Level, compact, and reinforce the foundation within the path area to ensure its bearing capacity meets the overall movement requirements of the dumper.

[0018] Among them, such as Figure 2 As shown, a curved temporary path 3 is designed between the original soil dumping conveyor belt system 1 and the newly built soil dumping mobile conveyor belt system for the overall movement of the soil dumping machine and unloading vehicle. The curved temporary path 3 consists of at least two tangent arcs, which are tangent to the center lines of the original soil dumping conveyor belt system 1 and the new soil dumping mobile conveyor belt system 2, respectively. In other words, the two ends of the curved temporary path 3 are tangent to the original soil dumping conveyor belt system 1 and the newly built soil dumping mobile conveyor belt system, respectively, which can smoothly and stably realize the relocation operation of the soil dumping machine. Moreover, the curved temporary path 3 can easily avoid some poor terrain on the walking path through its arc-shaped contour, which can further improve construction efficiency.

[0019] In this embodiment, both the dumping conveyor system and the newly built dumping mobile conveyor system are existing mining operation equipment. The dumper is a key piece of equipment in the continuous or semi-continuous mining process of large open-pit mines, mainly used to orderly pile up the stripped topsoil and rock to the dumping site. Its operating efficiency depends on two core components: one is a tracked walking device with high mobility, and the other is an unloading vehicle, an intermediate transfer device connecting the ground belt conveyor and the dumper. During operation, the unloading vehicle moves along the belt conveyor to receive material from the crushing system; the material is lifted and unloaded into the receiving arm of the dumper via a belt conveyor; the dumper conveys the material to the end of the discharge arm through its internal conveying system; supported by the tracked walking device, the dumper moves while discharging the material, forming a strip-shaped material pile; it also includes a support vehicle to ensure the stable operation of the receiving arm, generally supporting the front end of the receiving arm to prevent the cantilever from being too long and causing structural instability; when the receiving arm is attached to the support vehicle, the rigidity and safety of the whole machine can be significantly improved.

[0020] S2: Determine key parameters such as the safe distance and elevation difference between the tracked walking device of the dumper and the unloading vehicle track, as well as the safe distance between the tracked device and the slope, and delineate the tracked walking path range; specifically, the relevant parameters are designed as follows: the ground elevation difference between the unloading vehicle and the support vehicle and the tracked walking device must be less than 700mm; the center line of the tracked walking device must be at least 20m away from the center line of the unloading vehicle and the support vehicle track; the average ground pressure of the dumper installation site must be greater than or equal to 110KPa; the safe distance between the outermost tracked device of the tracked walking device and the slope must be at least 20m.

[0021] S3: Track system laying; including laying the tracks for the unloading vehicle and support vehicle and leveling the track for the tracked walking device; following the planned curved path, after cutting off the power and removing the conveyor belt, use an excavator or similar mechanical equipment to slowly drag the entire track system, including the track, sleepers, and roller frames, to the designed position of the temporary path, and then correct and fix it. The track laying accuracy must be strictly controlled to ensure the track gauge and smoothness.

[0022] S4: Control the soil dumper and unloading vehicle as a whole to travel along the temporary curved path 3 designed in S1 until they reach the new installation position; during the travel, in this embodiment, the ground height difference between the unloading vehicle and the support vehicle and the track travel device is 500mm to ensure stability; the distance between the center line of the track travel device and the center line of the unloading vehicle and the support vehicle's travel track is 30m, and the safe distance between the outermost track device of the track travel device and the slope is 40m to maximize safety.

[0023] The movement of the dumper is mainly controlled by the driver in the cab, using a variable frequency drive (VFD) motor to drive the tracked walking device, the unloading trolley, and the support trolley. The overall curved movement of the dumper begins with the tracked walking device moving forward. When the receiving arm approaches the rear of the receiving arm's support wheel, the tracked walking device stops immediately. The second step involves the unloading trolley and support trolley moving forward. When the receiving arm approaches the head of the receiving arm's support wheel, the unloading trolley and support trolley moving forward again stop immediately. These two steps are repeated to achieve the overall curved movement of the dumper.

[0024] In summary, this application proposes a method for the overall relocation of a mine dumping machine. It proposes a specific "S"-shaped temporary travel path and completes the temporary path track laying by protectively relocating the original conveyor belt track system. Simultaneously, the road in the dumping machine's track travel area is leveled and compacted. Finally, by controlling the alternating and synchronous operation of the dumping machine's own track travel device and the track travel device of the unloading vehicle / support vehicle, the dumping machine and unloading vehicle, with a total weight exceeding one thousand tons, are driven along the curved path to the new site. This method avoids cumbersome disassembly and assembly, significantly shortens the relocation period, reduces construction costs, and minimizes safety risks, resulting in significant economic and social benefits. It provides a safe and efficient solution for the rapid relocation of large-scale continuous transportation equipment in mines, with extremely broad market prospects. Moreover, it is highly effective; using this invention for dumping machine relocation can save costs and improve efficiency. It also has the advantage of broad application prospects and can be applied to the relocation of dumping machines in all open-pit coal mines, iron mines, and other mining enterprises using large dumping machines.
