Description

Technical Field

[0001] This invention belongs to the field of mining crushing technology, and more specifically, relates to a prefabricated crushing station. Background Technology

[0002] Mining crushing plants are primarily used for crushing and processing ores during mining operations. Currently, the structural components, retaining walls, and foundations of fixed, semi-fixed, and mobile crushing plants used in mines both domestically and internationally suffer from drawbacks such as complex installation, long construction periods, high costs, and difficulties in relocation. Among these, large-block reinforced concrete retaining walls and foundations are the most common. When a crushing plant needs to be relocated due to changes in the working face of the mining area, the existing reinforced concrete retaining walls and foundations are difficult to dismantle and cannot be reused. The high cost of constructing new reinforced concrete retaining walls and foundations also affects the construction progress and increases expenses. The development and application of efficient and flexible prefabricated crushing plants can reduce investment while ensuring construction progress. Therefore, this field has broad market prospects for promotion and application.

An impact crusher is mounted on the end of the suction pipe furthest from the connecting pipe, and the impact crusher is located on the crushing plant body, specifically on the right side of the processing box. The second conveyor belt device is also mounted on the crushing plant body.

[0004] For example, Chinese patent application No. 202210671896.0 discloses a mobile crushing plant. This application includes a tracked walking assembly, a mounting frame, a feeding assembly, a crushing assembly, and a discharging assembly. The tracked walking assembly includes a walking frame with a support column in the middle. The lower end of the support column is fixedly connected to the walking frame, and the upper end is hinged to the middle of the mounting frame. A rear support assembly is located below the rear end of the mounting frame. The rear support assembly includes a rear support plate and a rear hydraulic assembly. The rear hydraulic assembly is located between the rear support plate and the mounting frame. The upper end of the rear hydraulic assembly is connected to the mounting frame, and the lower end presses the rear support plate against the ground. Two sets of the rear hydraulic assemblies are respectively located on both sides of the mounting frame.

[0005] The two comparative documents mentioned above still do not provide an effective solution to the problems of difficulty in demolishing and non-reusability of existing reinforced concrete retaining walls and foundations when changing workplaces. Summary of the Invention

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) A prefabricated crushing station of the present invention includes a crushing platform and a crusher installed on the crushing platform. The crushing platform is positioned and installed by multiple fixed blocks, and a box is connected to the side of the crushing platform. The box is triangular in shape. By filling the triangular area with crushed stone, a slope for transport vehicles to travel is formed to complete the transfer and processing of crushed stone. At the same time, the crushing platform, fixed blocks, crusher and box are all detachably connected. Compared with traditional reinforced concrete retaining walls and foundations, the prefabricated crushing station of the present invention reduces the dismantling and relocation time of the crushing station and allows the crushing platform and triangular box to be reused.

[0023] (2) A prefabricated crushing station of the present invention further optimizes the design of the triangular box structure, which includes a frame, a first connecting plate and a support assembly. The support assembly includes a second connecting plate and a support plate. The support plate and the first connecting plate are connected to each other through a first mounting groove and a hook tongue. The second connecting plate and the support plate are connected through a connecting block and a second mounting groove. The end of the second mounting groove is provided with a barb to ensure the stability of the entire box structure. At the same time, a first diversion plate is provided at the bend where the support plate and the connecting block are connected. A second diversion plate is provided at the end of the second connecting plate and a third diversion plate is provided at the end of the frame. By setting multiple diversion plates, the resistance of the box to the crushed stone when it moves is reduced, and the triangular box is more convenient to be disassembled and moved as a whole.

[0024] (3) A prefabricated crushing station of the present invention, wherein the fixed pier includes a base pier and a top column inserted into the base pier, wherein the top column is hinged to a gripper by a hinge rod, the base pier has an active cavity for accommodating the gripper, and the bottom of the top column is connected to an elastic element; this design makes the base pier and the top column detachable. In use, the crushing platform is placed on the top column, and the weight of the crushing platform itself is used to insert the gripper into the active cavity of the base pier to complete the assembly between the two. At this time, the elastic element is compressed; when disassembly is required, the crushing platform is removed first, and under the restoring force of the elastic element, the top column drives the gripper to pop out from the active cavity, thereby realizing the reuse of the top column.

[0038] The present invention will be further described below with reference to specific embodiments.

[0039] Example 1

[0040] like Figure 1 As shown, a prefabricated crushing station according to this embodiment includes a crushing platform 1 and a crusher 2 installed on the crushing platform 1 for crushing ore. The crushing platform 1 is positioned and installed by multiple fixed blocks 3, and a box 4 is connected to the side of the crushing platform 1.

[0041] Specifically, refer to Figure 2 , Figure 3 , Figure 4 As shown, the crushing platform 1 includes a platform plate 11 and a base frame 12 connected to each other. A first column 13 is provided on the base frame 12, which is used to connect the box body 4. The platform plate 11, the base frame 12, and the first column 13 are all made of steel. The base frame 12 is connected to the platform plate 11 and the first column 13 by bolts to facilitate installation and disassembly.

[0042] The crusher 2 is mounted on the platform plate 11, and an overlapping plate 21 is provided between the crusher 2 and the first column 13. One end of the overlapping plate 21 is connected to the crusher 2, and the other end overlaps the first column 13. Fixing rods 23 are also provided on both sides of the crusher 2. One end of each fixing rod 23 is fixed to the platform plate 11, and the other end is connected to the crusher 2. The overlapping plate 21 and fixing rods 23 further ensure the stability of the connection between the crusher 2 and the platform plate 11.

[0043] The discharge port of the crusher 2 is connected to a conveyor belt 22 for transferring the crushed ore; in addition, in order to facilitate the transfer of ore into the crusher 2 by the transport vehicle, the feed port of the crusher 2 is lower than the top of the first connecting plate 42 of the housing 4.

[0044] like Figure 5 , Figure 6As shown, the housing 4 includes a frame 41, a first connecting plate 42, and a second column 46. The frame 41 is generally square and includes two end plates and two side plates. The second column 46 is mounted on the end plates of the frame 41, and the first connecting plate 42 is connected to the frame 41 via the second column 46. A slot 461 is provided at the top of the second column 46.

[0045] The first connecting plate 42 is provided with a cover plate 47, which is provided with a hook that cooperates with the top slot 461 of the second column 46 to ensure the stability of the connection between the first connecting plate 42 and the second column 46.

[0046] To further strengthen the connection between the first connecting plate 42 and the frame 41, a support component 43 is provided between the other end of the first connecting plate 42 and the frame 41.

[0047] refer to Figure 7 , Figure 8 As shown, the support assembly 43 includes a second connecting plate 431 and a support plate 432. The end of the second connecting plate 431 is connected to the end plate of the frame 41. One end of the support plate 432 is connected to the first connecting plate 42, and the other end is connected to the second connecting plate 431. Preferably, two sets of support plates 432 are provided and arranged in parallel.

[0048] Specifically, the first connecting plate 42 has a first mounting groove 421, and the second connecting plate 431 has a second mounting groove 433. One end of the support plate 432 is provided with a hook tongue 435, which cooperates with the first mounting groove 421 to complete the connection between the support plate 432 and the first connecting plate 42.

[0049] The other end of the support plate 432 is provided with a connecting block 44, which is inserted into the second mounting groove 433 to complete the connection between the support plate 432 and the second connecting plate 431. At the same time, the side of the second mounting groove 433 away from the first connecting plate 42 is provided with a barb 434 to enhance the limiting effect on the connecting block 44.

[0050] The support plate 432 has a first drainage plate 451 at the bend where it connects to the connecting block 44. The second connecting plate 431 has a second drainage plate 452 at its end near the first connecting plate 42. The frame 41 has a third drainage plate 453 on the inner side of its end plate away from the first connecting plate 42. The first drainage plate 451 is semi-cylindrical, the second drainage plate 452 is a vertically arranged arc plate, and the third drainage plate 453 has an arc-shaped cross-section. The multiple drainage plates effectively reduce the resistance from gravel encountered by the frame 41 during movement.

[0051] In addition, a support plate 432 may also be provided between the second column 46 and the side plate of the frame 41. The connection between the support plate 432 and the second column 46 and the frame 41 can be the connection method described above.

[0052] In this embodiment of a prefabricated crushing station, when in use, firstly, multiple fixed piers 3 are set at the selected pre-embedded points, and the foundation frame 12 is clamped on the fixed piers 3; then, the platform plate 11 and the first column 13 are installed on the foundation frame 12, and at the same time, the crusher 2 is installed on the platform plate 11.

[0053] Next, the frame 41 is placed at the predetermined location on the crushed stone platform, and the two sets of second columns 46 are installed on the end plates of the frame 41. Then, the first connecting plate 42 is installed on the second columns 46, and the cover plate 47 is installed on the first connecting plate 42, ensuring that the hooks on the cover plate 47 engage with the slots 461 of the second columns 46. At the same time, the first connecting plate 42 is connected to the first column 13.

[0054] Then, the second connecting plate 431 is installed on the end plate of the frame 41; next, the hook tongue 435 at one end of the support plate 432 is inserted into the first mounting groove 421 on the first connecting plate 42, and the connecting block 44 at the other end of the support plate 432 is inserted into the second mounting groove 433 on the second connecting plate 431. The other support plates are installed in the same way.

[0055] Next, the third diversion plate 453 is installed on the frame 41, completing the assembly of the entire housing 4. It should be noted that the first diversion plate 451 and the second diversion plate 452 can be pre-assembled before the housing 4 is assembled.

[0056] After the box 4 is assembled, pile up gravel inside the triangular box 4 until the gravel forms a slope, and the highest point of the slope is level with the top of the first connecting plate 42, so as to form a ramp that can be used by the transport vehicle.

[0057] This embodiment of a prefabricated crushing plant allows for threaded connections between its components. When the crushing plant needs to be moved, the crusher 2 and crushing platform 1 can be dismantled and transported first, exposing the housing 4. The entire housing 4 can then be pulled out of the gravel by a trailer and subsequently hoisted to the next construction site. This operation not only saves time required for dismantling the crushing plant but also allows for the reuse of the crushing platform 1 and housing 4, significantly reducing construction costs. Of course, the housing 4 can also be disassembled and transported as needed.

[0058] Example 2

[0059] This embodiment of the prefabricated crushing plant, based on embodiment 1, further optimizes the specific structure of the fixed pier 3 to achieve the reuse of the fixed pier 3, thereby further improving dismantling efficiency and reducing construction costs.

[0060] Specifically, refer to Figure 2 , Figure 9 As shown, the fixed pier 3 includes a foundation pier 31 and a top column 32 inserted into the foundation pier 31. The top column 32 has a slot for the foundation frame 12 to be inserted into.

[0061] The top column 32 is hinged to a clamp 33 via a hinge rod. A movable cavity for accommodating the clamp 33 is provided within the foundation pier 31, and the free end of the clamp 33 can extend through to the outer wall of the foundation pier 31. An elastic element 34 is connected to the bottom of the top column 32. The clamp 33 can be made of steel, and the elastic element 34 can be a spring. Specifically, in this embodiment, there are four fixed piers 3 and four clamps 33, and the foundation pier 31 is a concrete pier.

[0062] In use, the base frame 12 is inserted into the slot on the top column 32. At the same time, the weight of the base frame 12 allows the gripper 33 to be pushed out from the movable cavity inside the foundation pier 31, and the free end of the gripper 33 extends to the outside of the foundation pier 31, giving the foundation pier 31 buried underground a stronger grip.

[0063] When it is necessary to disassemble the base fixing pier 3, the base frame 12 clamped to the top of the top column 32 is removed, and the clamp 33 is retracted into the movable cavity under the elastic force of the spring. Even if the clamp 33 cannot be completely retracted into the movable cavity under the elastic force of the spring, the top column 32 can be pulled out from the movable cavity of the base pier 31 by a crane.

[0064] This embodiment of a prefabricated crushing plant achieves the recycling of the top column 32 by discarding the foundation pier 31 and removing the top column 32 along with its bottom-mounted springs and grippers 33. For subsequent use, only the foundation pier 31 needs to be re-fabricated, thus enabling the crushing plant to be mobile and reusable while minimizing its cost.

[0065] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
