Description

Technical Field

[0001] This invention belongs to the field of coal mining technology, specifically, it relates to a foundationless rapid relocation crushing system for open-pit coal mines. Background Technology

[0002] Coal, as one of the world's most important basic energy sources, occupies a pivotal position in the energy structure. Open-pit coal mining, due to its advantages such as high extraction efficiency and relatively low cost, is a crucial method of coal extraction. In the process of open-pit coal mining, coal crushing is an indispensable and critical step, and its efficiency and quality directly affect the subsequent processing and utilization of coal. As the core facility for coal crushing, the coal mine crushing station plays a vital role in ensuring the continuity and efficiency of coal production.

[0003] In existing coal mine crushing plant designs, the common practice is to design a foundation pit and install the crusher inside it. This layout allows coal-loaded trucks to drive to the edge of the pit and directly unload the material into the hopper above the crusher, facilitating material transport and the crushing process. However, in practice, trucks loaded with material frequently need to travel to the edge of the pit for unloading. Because the pit edge is adjacent to the foundation pit, its foundation is relatively weak due to the effects of pit excavation and frequent vehicle traffic. Therefore, a foundation needs to be constructed at this location. The traditional approach is to build a reinforced concrete retaining wall at the pit edge as a robust foundation structure to bear the weight of the trucks and the impact forces generated during unloading.

[0004] Constructing reinforced concrete retaining walls requires a large amount of building materials and manpower, undoubtedly increasing the civil engineering costs of coal mine crushing stations. Furthermore, during phased open-pit coal mining, the crushing station needs to be relocated to adapt to the new mining location as the mining area advances. However, the reinforced concrete retaining walls in traditional crushing stations serve as fixed foundation structures, making them difficult to move or dismantle, significantly reducing the flexibility of relocation during phased mining operations.

[0005] In conclusion, developing a rapid relocation crushing system for open-pit coal mines without foundations that can reduce civil engineering costs and has good relocation flexibility is of great practical significance. It will help improve the overall efficiency of open-pit coal mining and promote the sustainable development of the coal industry. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid relocation crushing system without foundation in open-pit coal mines, which solves the technical problem of high civil engineering costs caused by the need to construct reinforced concrete retaining walls along the pit of traditional crushing plants.

[0007] According to one aspect, at least one embodiment of the present invention provides a foundationless rapid relocation crushing system for open-pit coal mines, comprising a frame, a crusher, and a feeding conveyor. The frame is disposed within the pit, the crusher is mounted on the frame, and the feeding conveyor is disposed on the ground above one side of the pit. The discharge end of the feeding conveyor extends and connects to the frame for feeding material to the crusher. The feeding conveyor has a discharge area, which is configured to be spaced from the edge of the pit, and the discharge area is used to receive material unloaded by material transfer equipment.

[0008] According to an exemplary embodiment of this disclosure, the bottom of the frame is detachably provided with a base, the base being configured to be laid on the bottom of the pit, and the base having ear plates for connecting to hooks for relocation of equipment.

[0009] According to an exemplary embodiment of this disclosure, a feeding channel is provided between the unloading area and the crusher. The feeding channel surrounds the outside of the feeding conveyor to prevent material from scattering. A baffle is provided at the inlet of the feeding channel, and there is a gap between the baffle and the feeding conveyor. The baffle is used to block material from entering the feeding channel to control the thickness of the material layer.

[0010] According to an exemplary embodiment of this disclosure, the baffle is oscillatingly disposed at the inlet of the feed channel. A telescopic rod is hinged between the baffle and the inner top wall of the feed channel. A buffer spring is sleeved on the telescopic rod, and the two ends of the buffer spring are respectively connected to the two ends of the telescopic rod to provide the force for the extension of the telescopic rod. The baffle can swing inward toward the inside of the feed channel and allow the large piece of material to pass through when it is blocked, so as to avoid the feeding conveyor from jamming.

[0011] According to an exemplary embodiment of this disclosure, an emergency stop switch is provided on the top wall of the feed channel. The emergency stop switch is electrically connected to the controller. A pressing rod is slidably provided on the baffle. A pressing spring is sleeved on the pressing rod. The two ends of the pressing spring act on the baffle and the pressing rod respectively. The pressing rod can press the emergency stop switch after the baffle swings inward toward the feed channel, so that the controller transmits a stop signal to the feeding conveyor to prevent large pieces of material from entering the crusher.

[0012] According to an exemplary embodiment of this disclosure, a support sleeve assembly is provided at the bottom of the feeding conveyor, the support sleeve assembly being pre-buried underground to support the feeding conveyor.

[0013] According to an exemplary embodiment of this disclosure, the support sleeve assembly includes an inner cylinder, and an inclined anchor plate that slides through the side wall of the inner cylinder and engages with the side wall of the inner cylinder is provided. There are multiple inclined anchor plates, and the sliding direction has an angle with the axis of the inner cylinder. The inclined anchor plate can slide out of the inner cylinder and insert into the soil after the inner cylinder is pre-buried underground.

[0014] According to an exemplary embodiment of this disclosure, a sliding block is slidably disposed inside the inner cylinder. There are multiple sliding blocks, and each sliding block is provided with at least two inclined anchor plates. The multiple inclined anchor plates on the same sliding block are parallel to each other.

[0015] According to an exemplary embodiment of this disclosure, the support sleeve assembly further includes an outer cylinder, which is disposed at the bottom of the feeding conveyor and sleeved outside the inner cylinder. The outer cylinder is slidably engaged with the inner cylinder. Both the outer cylinder and the inner cylinder have through holes for installing locking pins on their side walls. An expansion rod is disposed inside the outer cylinder, and the bottom end of the expansion rod and the top of the sliding block have inclined surfaces. After both the outer cylinder and the inner cylinder are pre-buried underground, the outer cylinder can slide down after the locking pin is pulled out, and the expansion rod can slide down synchronously under the drive of the outer cylinder and push the sliding block outward, so that the inclined anchor plate slides out of the inner cylinder and inserts into the soil.

[0016] According to an exemplary embodiment of this disclosure, the frame is provided with a feed chute and a discharge conveyor. The feed chute is located between the discharge end of the feed conveyor and the crusher, and the discharge conveyor is located below the crusher.

[0017] The present invention provides a foundationless rapid relocation crushing system for open-pit coal mines. By setting the unloading area of ​​the feeding conveyor away from the pit edge, the system utilizes the natural strength of the ground to bear the load during unloading, avoiding the civil engineering work of building reinforced concrete retaining walls along the pit edge. This not only reduces the use of a large amount of building materials but also reduces the manpower required for construction, thereby lowering the civil engineering cost of the coal mine crushing station.

[0029] like Figures 1-5 The diagram illustrates a foundationless, rapid-installation crushing system for open-pit coal mines according to an embodiment of the present invention, comprising a frame 1, a crusher 2, and a feeding conveyor 3. The frame 1 is installed within the pit of the open-pit coal mine, providing an installation platform for the crusher 2 and withstanding the impact and vibration generated during coal crushing, ensuring smooth crushing operations. The feeding conveyor 3 is laid on the compacted ground above the pit, with its discharge end extending and connecting to the frame 1, forming a material conveying channel. The feeding conveyor 3 is provided with a discharge area 301, which is spaced from the edge of the pit.

[0030] When a material handling device (such as a truck) fully loaded with coal travels to the unloading area 301 of the feeding conveyor 3, it unloads the coal into the unloading area 301. Because the unloading area 301 is spaced apart from the pit rim, the ground can stably withstand the weight and impact generated during unloading. The feeding conveyor 3 transports the coal from the unloading area 301 to the discharge end via the conveyor belt, and the coal is finally fed into the crusher 2 mounted on the frame 1. The crusher 2 crushes the incoming coal, breaking large pieces into smaller pieces that meet the requirements, thus completing the coal crushing process.

[0031] During phased mining in open-pit coal mines, the crushing system needs to be relocated as the mining area advances. Thanks to the design of this scheme, the relocation process is simplified. Simply use traction or relocation equipment to move the feeding conveyor 3 from its original location to the new mining location, then re-lay the feeding conveyor 3 at the new location, connecting its discharge end to the frame 1 installed in the pit. This restores the normal operation of the crushing system, improving the flexibility of relocation during phased mining and enabling rapid response to changes in the mining area.

[0032] See Figure 6 In traditional methods, because the pit edge is close to the foundation pit, the foundation is relatively weak due to the combined effects of pit excavation and frequent vehicle traffic, requiring the construction of reinforced concrete retaining walls for reinforcement. However, this system sets the unloading area 301 of the feeding conveyor 3 away from the pit edge, utilizing the natural strength of the ground to bear the load during unloading. This avoids the need for civil engineering work involving constructing reinforced concrete retaining walls along the pit edge, reducing both the use of building materials and the manpower required for construction, thereby lowering the civil engineering costs of the coal mine crushing station.

[0033] like Figure 6 In traditional crushing plants, reinforced concrete retaining walls serve as fixed foundation structures. Dismantling and rebuilding them during relocation is difficult and costly, limiting the flexibility of the crushing plant's relocation. In contrast, the independent installation of the feeding conveyor 3 in this crushing system allows for simple relocation to a new site for refurbishment, eliminating the need for large-scale demolition and reconstruction of the foundation structure. This enables rapid adaptation to changes in the mining area, improving the efficiency and economy of open-pit coal mining.

[0034] As a specific embodiment, in this crushing system, the bottom of the frame 1 is detachably mounted on the base 4, which is laid at the bottom of the pit. In traditional crushing plant construction, to provide a stable connection foundation for the column feet at the bottom of the frame 1, civil engineering foundations need to be constructed at the bottom of the pit, which is not only time-consuming, labor-intensive, and resource-intensive, but also requires the removal of these civil engineering foundations when the crushing plant is relocated. In this solution, the base 4 replaces the traditional civil engineering foundation and is laid directly at the bottom of the pit, providing a support platform for the frame 1. Ear plates 401 are provided on the base 4, which are used to connect with the hooks of the relocation equipment (such as cranes or tractors with hook devices). The feed chute 12 is located between the discharge end of the feeding conveyor 3 and the crusher 2, and its function is to guide the material to enter the crusher 2 continuously and stably. The discharge conveyor 13 is located below the crusher 2 and its function is to transport the material crushed by the crusher 2 to the next process.

[0035] When the open-pit coal mine advances and the crushing system needs to be relocated, the relocation equipment moves to the location of base 4. The hook of the relocation equipment connects to the ear plate 401 on base 4, and the base 4 is lifted and moved by applying force through the hook. Base 4 replaces the traditional civil engineering foundation, eliminating the need for complex demolition work and making the relocation process simple and quick. After reaching the new mining location, base 4 is re-laid at the bottom of the new pit, and necessary adjustments and fixation are made to complete the relocation of the crushing system, allowing it to quickly resume operation.

[0036] The feeding conveyor 3 transports the coal unloaded from the material transfer equipment in the unloading area 301 to the discharge end. The coal falls from the discharge end into the feeding chute 12, which guides the coal into the crusher 2. The crusher 2 crushes the coal into suitable particle sizes. The crushed material falls from the discharge port of the crusher 2 and enters the discharge conveyor 13 below. The discharge conveyor 13 transports the crushed material to the next process, completing the coal crushing and conveying process.

[0037] As a specific embodiment, a feeding channel 5 is provided between the unloading area 301 and the crusher 2. The feeding channel 5 surrounds the outside of the feeding conveyor 3, and its function is to provide a guiding path for the material and prevent the material from scattering in all directions during the conveying process. A baffle 6 is installed at the inlet of the feeding channel 5, and a gap is maintained between the baffle 6 and the feeding conveyor 3 to allow material to pass through, while controlling the thickness of the material layer entering the feeding channel 5 to avoid excessive material entering and causing blockage problems in the subsequent conveying and crushing processes.

[0038] A swaying baffle 6 is installed at the inlet of the feed channel 5. A telescopic rod 7 is hinged between the baffle 6 and the inner top wall of the feed channel 5. The telescopic rod 7 consists of two nested rods, with a buffer spring 8 fitted onto it. The two ends of the buffer spring 8 are connected to the two rods respectively. The function of the buffer spring 8 is to provide extension force to the telescopic rod 7, thereby maintaining the stable position of the baffle 6 under normal conditions. When material is conveyed from the feeding conveyor 3 to the feed channel 5, the force exerted on the baffle 6 by normally sized material is insufficient to overcome the elastic force of the buffer spring 8, and the baffle 6 remains stationary, thus controlling the material layer thickness. When large pieces of material cannot pass through the gap between the baffle 6 and the feeding conveyor 3 and become stuck, the material will exert greater pressure on the baffle 6. This pressure exceeds the elastic force of the buffer spring 8, causing the baffle 6 to swing inwards towards the inside of the feed channel 5, thus clearing the passage for large pieces of material and preventing them from getting stuck at the inlet, thereby preventing damage to the feeding conveyor 3 or the baffle 6.

[0039] An emergency stop switch 9 is installed on the top wall of the feed channel 5. The emergency stop switch 9 is electrically connected to the controller and is responsible for transmitting control signals. A pressing rod 10 is slidably mounted on the baffle 6, and a pressing spring 1001 is installed between the pressing rod 10 and the baffle 6. The pressing spring 1001 provides flexible pressing force for the pressing rod 10, avoiding potential damage to the emergency stop switch 9 that might be caused by a rigid connection between the pressing rod 10 and the baffle 6. When a large piece of material pushes the baffle 6 to swing inward into the feed channel 5 to a certain angle, the pressing rod 10 on the baffle 6 will move with the swing of the baffle 6 until it presses the emergency stop switch 9. After the emergency stop switch 9 is pressed, it transmits a signal to the controller. Upon receiving the signal, the controller quickly issues a stop command to the feeding conveyor 3, causing the feeding conveyor 3 to stop conveying material in time, preventing large pieces of material from entering the crusher 2 and preventing the crusher 2 from being damaged due to processing oversized materials.

[0040] As a specific embodiment, to ensure the support stability of the feeding conveyor 3, a support sleeve assembly 11 is provided at its bottom. Multiple inclined anchor plates 1102 are provided through the side wall of the inner cylinder 1101 in the support sleeve assembly 11. These inclined anchor plates 1102 slide in cooperation with the side wall of the inner cylinder 1101, and the sliding direction of the inclined anchor plates 1102 is designed to form an angle with the axis of the inner cylinder 1101. Multiple sliding blocks 1103 are slidably arranged inside the inner cylinder 1101, and each sliding block 1103 is connected to at least two mutually parallel inclined anchor plates 1102, so that the inclined anchor plates 1102 can play a sliding guiding role during sliding, ensuring the accuracy of the sliding direction of the inclined anchor plates 1102.

[0041] The support sleeve assembly 11 also includes an outer cylinder 1104, which is located at the bottom of the feeding conveyor 3 and sleeved around the inner cylinder 1101, slidingly engaging with it. Both the outer cylinder 1104 and the inner cylinder 1101 have through holes on their side walls for installing locking pins 1105. Inserting the locking pins 1105 restricts the relative sliding between the outer cylinder 1104 and the inner cylinder 1101, facilitating the insertion of the entire support sleeve assembly 11 into the soil during pre-embedding. An expansion rod 1106 is installed inside the outer cylinder 1104, with both the bottom end of the expansion rod 1106 and the top of the sliding block 1103 having inclined surfaces.

[0042] When installing the support sleeve assembly 11, first insert the locking pin 1105 into the through holes on the side walls of the outer cylinder 1104 and the inner cylinder 1101, so that the outer cylinder 1104 and the inner cylinder 1101 are in a relatively fixed state. At this time, the entire support sleeve assembly 11 can be inserted into the underground soil as a whole. After the outer cylinder 1104 and the inner cylinder 1101 are pre-buried underground, pull out the locking pin 1105 to release the locking state between the outer cylinder 1104 and the inner cylinder 1101. At this time, under the action of external force (such as the weight of the feeding conveyor 3 or additional pressure), the outer cylinder 1104 slides downward. Since the expansion rod 1106 is connected to the outer cylinder 1104, the expansion rod 1106 will slide down synchronously with the outer cylinder 1104. When the expansion rod 1106 slides down, its bottom inclined surface comes into contact with the top inclined surface of the sliding block 1103 and generates a force, pushing the sliding block 1103 to slide outward. This, in turn, causes the inclined anchor plate 1102 connected to the sliding block 1103 to slide out from the inner cylinder 1101. The inclined anchor plate 1102 is inserted into the soil at an inclined angle, forming a stable support structure in the soil. This method of pre-embedding the outer cylinder 1104 and the inner cylinder 1101 and then extending the inclined anchor plate 1102 avoids the problem of the inclined anchor plate 1102 not being able to be directly inserted into the soil if it extends prematurely.

[0043] The inclined anchor plate 1102 inserted into the soil improves the support stability of the feeding conveyor 3, which can better resist the forces borne by the feeding conveyor 3 during operation, ensuring that the feeding conveyor 3 remains stable during long-term operation and preventing the feeding conveyor 3 from sinking into the soil after long-term operation.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
