Description

[Technical Field]

[0001] This utility model relates to the field of large material stacking technology, and specifically to a stacking device for large material stacking sites. [Background Technology]

[0002] In the storage of bulk materials such as ore, coal, and sand, the site coverage and stability of the stacking equipment directly determine storage efficiency and operational safety. Traditional cloth belt conveyor stacking systems have many limitations. Existing stacking equipment often uses linear or fixed track layouts, leading to excessive concentration of stacking areas in a specific part of the site, resulting in significant space idleness and significantly low site utilization. Furthermore, traditional stacking systems suffer from poor stability during operation, especially in long-span operations, where equipment is prone to swaying or even tipping over, threatening operational safety and increasing additional reinforcement costs. Moreover, existing equipment has extremely high requirements for site flatness, and its adaptability is severely insufficient when facing complex terrain or sloping sites, making it difficult to meet the urgent needs of modern large-scale material storage sites for efficient, flexible, and stable stacking operations.

[0003] To address these issues, extensive research and technological innovation have been conducted both domestically and internationally in the field of stockpiling equipment in recent years. However, existing stockpiling equipment suffers from the following common problems regarding site utilization, mobility stability, and adaptability to complex terrain: limited stockpiling range; fixed or monorail mobile equipment has a limited stockpiling range, resulting in low site utilization; traditional support designs are prone to swaying or even overturning during long-span operations, requiring additional reinforcement measures and increasing manufacturing costs; and they have high requirements for site flatness and poor slope adaptability.

[0004] Therefore, there is an urgent need for a new type of stacking vehicle frame device to significantly improve site utilization and site adaptability. [Utility Model Content]

[0005] The purpose of this invention is to solve the key technical problems of traditional cloth belt conveyor stacking systems, such as low site utilization, poor stability, and insufficient site adaptability. It provides a stacking device for large material stacking sites, optimizes the stacking trolley frame structure and integrates a high-efficiency mobile trolley device, significantly expands the stacking range, improves the stability and adaptability of the equipment under complex working conditions, and thus fully meets the requirements of modern large material stacking sites for efficient, flexible and stable stacking operations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A stacking device for large material storage areas includes a main frame and a mobile trolley device mounted on the main frame.

[0008] The main frame includes a main frame frame, a first track mounted on the bottom frame of the main frame frame, first wheels and a first motor located at the bottom of both ends of the main frame. The first wheels travel on a preset side track. The output end of the first motor is connected to the first wheels to drive them to move back and forth on the side track.

[0009] The main frame contains a laterally movable subframe. The subframe includes a subframe frame, second traveling wheels, idlers, a conveyor belt, a second traveling motor, and a conveyor motor. The second traveling wheels are mounted on the bottom of the subframe frame and driven by the second traveling motor to move on a first track. The idlers are mounted on the subframe frame to support the conveyor belt. The conveyor motor can rotate forward or backward to drive the conveyor belt. The length of the subframe is ≥1 / 2 the length of the main frame.

[0010] The main frame is provided with a feeding port in the middle. The main frame also includes an auxiliary support structure. One end of the auxiliary support structure is fixedly connected to the main frame frame, and the other end extends downward at an angle. A third traveling wheel and a third traveling motor that drives the third traveling wheel are provided at the bottom. The third traveling wheel travels on the central track, which is parallel to the side track.

[0011] The mobile trolley device is fixedly installed on the auxiliary support structure. The mobile trolley device includes a trolley frame and a conveyor body set on the trolley frame. The conveyor body includes a feeding belt and a feeding motor that drives the feeding belt. The discharge port of the conveyor body passes through the discharge port of the main frame and is located directly above the conveyor belt of the auxiliary frame, ensuring that the material can fall smoothly from the feeding belt through the discharge port onto the conveyor belt of the auxiliary frame.

[0012] In a further optimization, a material guiding and buffering assembly is provided between the discharge port and the discharge port. The material guiding and buffering assembly includes a corrugated pipe and a guide plate. The guide plate is installed inside the corrugated pipe and its tilt angle is adjustable.

[0013] Further optimized, the height difference H between the feed belt outlet and the conveyor belt satisfies 500mm≤H≤1500mm, and the feed belt running direction forms an angle of 20°-65° with the central track.

[0014] In a further optimized configuration, the auxiliary support structure includes a support beam and a support longitudinal beam, which form a grid structure, and the trolley frame is mounted on the grid structure.

[0015] In a further optimized configuration, the main frame is a rectangular frame welded from high-strength steel. The surface of the frame is reinforced by several connecting steel bars to form multiple small rectangular frames. The interior of each small rectangular frame is reinforced with cross-shaped reinforcing bars, X-shaped intersecting reinforcing ribs, or star-shaped reinforcing bars.

[0016] Furthermore, the conveyor body also includes a self-aligning idler roller correction device, which is installed below the feeding belt.

[0017] Further optimized, the first track surface is provided with anti-slip texture, and the rim of the second traveling wheel is provided with a groove structure that engages with the anti-slip texture.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model innovatively integrates a main frame, a sub-frame, and a mobile trolley device to form a highly efficient, flexible, and stable material stacking system. The main frame is equipped with a first traveling wheel and a first traveling motor, enabling stable reciprocating movement on a pre-set edge track, providing a solid foundation and reliable longitudinal movement capability for the entire stacking device. The mobile trolley device is mounted on an auxiliary support structure of the main frame, which is equipped with a third traveling wheel and a third traveling motor. This auxiliary support structure drives the mobile trolley device to move on the central track. The discharge port of the mobile trolley device precisely connects with the conveyor belt of the sub-frame, ensuring that materials can be smoothly transferred from the mobile trolley device to the conveyor belt of the sub-frame. The sub-frame can move laterally, cooperating with the conveyor motor to drive the conveyor belt. When the material reaches the edge of the conveyor belt, it falls into the material yard to be stacked, and the second traveling wheel is driven by a second traveling motor to move on the first track, realizing material stacking at any point on the edge track, effectively utilizing the space while making material transportation more precise and efficient. This unique structural design allows the stacking device to move flexibly in large material storage areas, both longitudinally and laterally, making full use of its capabilities, greatly improving site utilization, elevating the flexibility of stacking operations to a new level, and significantly enhancing the stability and adaptability of the equipment under complex working conditions, providing strong support for modern material stacking operations.

[0020] 2. The auxiliary support structure adopts a grid-like structure formed by supporting crossbeams and longitudinal beams, providing a solid and stable installation foundation for the trolley frame. The grid-like structure possesses excellent load-bearing capacity and mechanical properties, effectively distributing various forces generated during operation of the moving trolley device and significantly enhancing the structural stability of the entire stacking device. Simultaneously, this design facilitates the installation and positioning of the trolley frame, improving equipment assembly efficiency and maintenance convenience.

[0021] 3. The main frame is a rectangular frame welded from high-strength steel, reinforced with connecting steel bars to form multiple smaller rectangular frames. Internally, it is further reinforced with cross-shaped reinforcing bars, X-shaped intersecting reinforcing ribs, or star-shaped reinforcing bars, significantly enhancing the overall strength and rigidity of the main frame. This allows it to easily withstand various loads and stresses under complex conditions in large material storage areas, effectively resisting the risk of deformation and damage, extending equipment lifespan, ensuring long-term stable operation of the stacking operation, and providing a solid guarantee for the reliable operation of the entire stacking device.

[0032] Example 1

[0033] Please refer to Figures 1-6 A stacking device for large material storage areas includes a main frame 1 and a mobile trolley device 200 mounted on the main frame 1.

[0034] The main frame 1 includes a main frame 11, a first track 12 mounted on the bottom frame of the main frame 11, first wheels 13 and a first motor located at the bottom of both ends of the main frame 1. The first wheels 13 travel on a preset side track 51. The output end of the first motor is connected to the first wheels 13 to drive them to move back and forth on the side track 51.

[0035] The main frame 1 is equipped with a laterally movable sub-frame 2. The sub-frame 2 includes a sub-frame frame 21, second traveling wheels 22, idlers 23, a conveyor belt 24, a second traveling motor 25, and a conveyor motor 26. The second traveling wheels 22 are installed at the bottom of the sub-frame frame 21 and are driven by the second traveling motor 25 to move on the first track 12. The idlers 23 are installed on the sub-frame frame 21 to support the conveyor belt 24. The conveyor motor 26 can rotate forward or reverse to drive the conveyor belt 24. The length of the sub-frame 2 is ≥1 / 2 the length of the main frame 1.

[0036] The main frame 1 is provided with a feeding port 3 in the middle. The main frame 1 also includes an auxiliary support structure 15. One end of the auxiliary support structure 15 is fixedly connected to the main frame frame 11, and the other end extends downward at an incline. A third traveling wheel 151 and a third traveling motor 152 for driving the third traveling wheel are provided at its bottom. The third traveling wheel 151 travels on the central track 52. The central track 52 and the side track 51 are parallel to each other.

[0037] The mobile trolley device 200 is fixedly installed on the auxiliary support structure 15. The mobile trolley device 200 includes a trolley frame 202 and a conveyor body 203 set on the trolley frame 202. The conveyor body 203 includes a feeding belt 204 and a feeding motor 205 that drives the feeding belt 204. The discharge port 208 of the conveyor body 203 passes through the discharge port 3 of the main frame 1 and is located directly above the conveyor belt 24 of the auxiliary frame 2, ensuring that the material can fall smoothly from the feeding belt 204 into the conveyor belt 24 of the auxiliary frame 2 through the discharge port 208.

This design fully considers the parabolic trajectory and accumulation characteristics of the material during its descent, ensuring a smooth transition of the material onto the conveyor belt 24 while utilizing the material's falling potential energy to improve conveying efficiency.

[0044] The auxiliary support structure includes support beams and support longitudinal beams, which form a grid structure. The trolley frame 202 is mounted on this grid structure. This provides a stable mounting base for the mobile trolley device 200 while maintaining the stability of the main frame during material stacking.

[0045] The main frame 11 is a rectangular frame welded from high-strength steel. The surface of the frame is reinforced by several connecting steel bars to form multiple small rectangular frames. The interior of each small rectangular frame is reinforced with cross-shaped reinforcing bars, X-shaped intersecting reinforcing ribs, or star-shaped reinforcing bars to ensure that the main frame 1 has sufficient strength and rigidity to withstand various loads during the material stacking operation.

[0046] The conveyor body 203 also includes a self-aligning idler roller correction device, which is installed below the feeding belt 204. This device prevents belt misalignment or slippage, ensures stable belt operation, and improves the accuracy and reliability of material conveying.

[0047] The surface of the first track 12 is provided with anti-slip texture, and the rim of the second traveling wheel 22 is provided with a groove structure that engages with the anti-slip texture. This enhances the friction and adhesion between the traveling wheel and the track, effectively preventing the traveling wheel from slipping or spinning, improving the grip performance and transmission efficiency of the traveling wheel, and ensuring the stability and accuracy of the main frame 1 and the sub-frame 2 during movement.
