Abstract
Description
[Technical Field]
[0001] This utility model relates to the technical field of special site material stacking equipment, specifically to a mobile material stacking vehicle frame with stable support. [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 racks typically employ linear or fixed track layouts, resulting in the stacking area being concentrated in a certain area, failing to fully utilize site space and causing low site utilization. Furthermore, traditional systems suffer from poor stability, low operational efficiency, and poor flexibility during stacking, making it difficult to meet the demands of modern workplaces for efficient, flexible, and stable stacking equipment. Traditional support designs are prone to swaying or even overturning during long-span operations, requiring additional reinforcement measures and increasing manufacturing costs; they also have high requirements for site flatness and poor slope adaptability.
[0003] Therefore, there is an urgent need for a new type of stacking car frame structure to significantly improve site utilization and site adaptability. [Utility Model Content]
[0004] The purpose of this invention is to address the problems of limited coverage and insufficient stability of traditional stacking equipment by providing a mobile stacking vehicle frame with stable support, which can achieve stable stacking process and full coverage stacking within the rectangular area defined by the edge track, eliminating blind spots at the corners of traditional equipment and significantly improving site utilization.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A movable stacking car frame with stable support includes a main frame, a sub-frame installed inside the main frame, and a discharge port installed in the middle of the main frame and located on the upper part of the sub-frame.
[0007] 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.
[0008] The subframe includes a subframe frame, a second traveling wheel, a roller, a conveyor belt, a second traveling motor, and a conveyor motor. The second traveling wheel is installed at the bottom of the subframe frame. The second traveling motor is connected to the second traveling wheel to drive it to move back and forth on the first track. The roller is installed on the subframe frame to support the conveyor belt. The conveyor motor can rotate forward or backward to drive the conveyor belt to move.
[0009] The length of the subframe is ≥ 1 / 2 the length of the main frame, and the discharge port is located on the conveyor belt.
[0010] In a further optimized configuration, the support structure is also provided with a central track, and an auxiliary support structure is provided in the middle of the main frame. A third traveling wheel is provided at the bottom of the auxiliary support structure, and the third traveling wheel travels on the central track. The central track is parallel to the side tracks.
[0011] In a further optimized configuration, the first and third wheels are positioned on the same horizontal plane.
[0012] In a further optimized configuration, the first and third wheels are positioned on the same horizontal plane.
[0013] In a further optimized version, the main frame is a rectangular frame welded from high-strength steel, and the surface of the frame is reinforced by several connecting steel bars to form multiple small rectangular frames.
[0014] Further optimization involves reinforcing the interior of the small rectangular frame with diagonal reinforcing strips, cross reinforcing strips, or star-shaped reinforcing strips.
[0015] Further optimized, both the first and second traveling wheels are equipped with braking devices.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. This utility model, through the cooperation of the main frame and the sub-frame, allows the sub-frame to move within the main frame. The length of the sub-frame is ≥1 / 2 the length of the main frame, enabling material to be stacked without dead angles within the width range. The second traveling wheels at both ends of the main frame travel on the preset edge track, allowing the stacking vehicle to move within the specified track range, achieving material stacking without dead angles within the track length range. The above cooperation enables material stacking operations without dead angles within the track range at both ends, improving the utilization rate of the site, the efficiency of stacking, and the flexibility.
[0018] Furthermore, the stacker frame travels on the edge track via a second set of wheels. This edge track can be elevated as needed, and as long as it is parallel, it will not affect the normal operation of the stacker frame, even if the track has a slight slope or curvature. This design significantly improves the stacker frame's adaptability to different terrains, making it suitable for various complex terrains, such as mines and other scenarios with limited space, greatly expanding the equipment's application range.
[0019] 2. The support structure consists of three columns, with a central track on the upper part of the middle column. The third traveling wheel at the bottom of the auxiliary support structure in the middle of the main frame travels on the central track, enabling the stacking frame to adapt to a larger area and further improving the utilization rate of the site and the flexibility of stacking.

[0028] Example 1
[0029] refer to Figure 1 , Figure 2 , Figure 4 A movable stacking car frame with stable support includes a main frame 1, a sub-frame 2 installed in the main frame 1, and a discharge port 3 installed in the middle of the main frame and located on the upper part of the sub-frame 2.
[0030] 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.
[0031] The subframe 2 includes a subframe frame 21, a second traveling wheel 22, a roller 23, a conveyor belt 24, a second traveling motor 25, and a conveyor motor 26. The second traveling wheel 22 is installed at the bottom of the subframe frame 21. The second traveling motor 25 is connected to the second traveling wheel 22 to drive it to move back and forth on the first track 12. The roller 23 is installed on the subframe frame 21 to support the conveyor belt 24. The conveyor motor 26 can rotate forward or reverse to drive the conveyor belt 24 to move.
[0032] The length of the subframe 2 is ≥ 1 / 2 the length of the main frame 1, and the discharge port 3 is located on the conveyor belt 24.
[0033] During the stacking operation, the material to be stacked falls from the discharge port 3 directly onto the conveyor belt 24 of the subframe 2. After the conveyor motor 26 starts, the conveyor belt 24 begins to move, transporting the material from the discharge position to the end of the conveyor belt and unloading it, thus realizing the transfer and stacking of the material. Since both the subframe frame 21 and the main frame frame 11 are open frame structures, the material can fall directly and smoothly into the stockyard to be stacked without the need for additional guiding or auxiliary devices, simplifying the stacking process.
[0034] The length of the subframe 2 is greater than or equal to half the length of the main frame 1. More preferably, the length of the subframe 2 is greater than or equal to half the length of the main frame 1 plus half the length of the discharge port. The discharge port 3 is located on the conveyor belt 24, which ensures that the material coming down from the discharge port will fall onto the conveyor belt 24, thereby ensuring that the material can be transported to any point on the main frame span by the conveyor belt.
[0035] In a further optimization, both the first traveling wheel 13 and the second traveling wheel 22 are equipped with braking devices.
[0036] The length of the subframe 2 is greater than or equal to half the length of the main frame 1, and it can move back and forth along the first track 12 on the main frame frame 11 via the second traveling wheel 22 driven by the second traveling motor 25. Combined with the forward and reverse function of the conveyor motor 26, the subframe 2 can move flexibly within the length range of the main frame 1 and stack materials, ensuring that there are no dead corners in the material stacking area covered by the main frame 1. At the same time, the main frame 1 moves on the edge site track 51 via the first traveling wheel 13 driven by the first traveling motor, further expanding the working range of the stacking frame and realizing comprehensive material stacking within the coverage area of the edge site track 51, significantly improving site utilization and material stacking efficiency.

[0046] Subframe frame 21: Installed inside the main frame 1;
[0047] Second traveling wheels 22: Installed at the bottom of the sub-frame 21, a total of 8 sets, rolling in cooperation with the first track 12, driving the sub-frame 21 to move on the first track 12;
[0048] Idler 23: Used on the subframe frame 21 to support the conveyor belt 24 and ensure the stability of the conveyor belt during material transportation. Idler 23 can be set only in the upper half of the conveyor belt or along the entire conveyor belt.
[0049] Conveyor belt 24: Driven by conveyor motor 26, it makes continuous cyclical motion.
[0050] Conveyor motor 26: A variable frequency motor is used, and a speed reducer can also be set according to the actual situation.

[0055] In a further optimization, when the width of the site where materials need to be stacked is very large, a central site track 52 is set between the two side site tracks 51, parallel to the side tracks; at this time, the support structure consists of 3 columns.
[0056] Auxiliary support structure 15: It is set in the middle of the main frame 1 and connected to the main frame frame 11 by bolts. The bottom is equipped with a third traveling wheel 151, which travels on the track 52 in the middle of the site. The third traveling wheel 151 can be equipped with a separate traveling motor, or it can be driven by no motor. In this case, it travels under the drive of the first traveling wheel 13.
[0057] The first and third wheels are located on the same horizontal plane.
[0058] The first traveling wheel 13 and the third traveling wheel 151 are equipped with hydraulic disc brakes.
