Description

Technical Field

[0001] This utility model relates to the field of waste compression box technology, specifically a buried lifting compression box assembly. Background Technology

[0002] Underground compactor bins, as a highly efficient waste disposal device, play a crucial role in modern urban environmental management. These bins are typically installed underground, collecting and compressing waste to significantly reduce its volume and improve the efficiency of waste storage and transportation. Their underground installation not only makes effective use of space but also reduces the impact on the surface environment, minimizing the effects of odors and noise generated during waste disposal, and also improves the overall urban landscape to some extent.

[0003] Existing underground waste compactors utilize lifting mechanisms, such as scissor-type lifting mechanisms, which increase the overall height of the equipment. This necessitates deeper pits for installation, occupying excessive underground space and increasing construction costs and difficulty. Furthermore, some compactors lack effective waste containment and collection measures during dumping and transfer, leading to waste scattering, causing environmental pollution, and increasing the burden of subsequent cleanup. Moreover, due to unreasonable structural design, existing compactors are prone to tilting during loading and unloading, making it difficult to easily enter and exit the lifting frame and easily causing damage to the lifting mechanism due to unbalanced forces, further affecting the overall efficiency of waste treatment. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an underground lifting compression box assembly.

[0005] The technical solution of this utility model is as follows:

[0006] An underground lifting compression box assembly includes an underground support component, wherein a lifting plate for supporting the compression box is slidably disposed within the support component.

[0007] Multiple lifting cylinders are installed through the lifting plate, with the output ends of the multiple lifting cylinders facing downwards and fixed to the bottom end of the support assembly, and their outer cylinders fixed to the lifting plate;

[0008] The bottom of the compression box is equipped with multiple rollers, and the lifting plate has multiple strip grooves for limiting the rollers.

[0009] The rollers and the strip grooves are specifically designed as follows: four rollers are arranged in a rectangular pattern at the four corners of the bottom of the compression box, and two parallel strip grooves are provided, with the spacing between them being the same as the distance between the two rollers in the width direction.

[0010] In order for the compression box to move to the middle position of the lifting plate, the length of the strip groove is not less than the distance between the two rollers in the length direction, and the two strip grooves are symmetrically opened with respect to the mid-plane along the length direction of the lifting plate.

[0011] The support component is specifically designed as follows: the support component includes a base, and multiple columns are installed at the four corners of the upper surface of the base. The lifting plate is slidably arranged between the multiple columns.

[0012] To improve the stability of the lifting platform, multiple mounting brackets are provided on the bottom edge of the lifting platform, and guide wheels are installed at the bottom of the mounting brackets. The guide wheels are in contact with the column and are in rolling connection.

[0013] To facilitate the shielding of the compression box at the top, both for protection and to reduce the spread of garbage odor inside the compression box, two sets of mounting columns are installed parallel to each other on the upper edge of the lifting plate, with multiple columns in each set, and an end cap is provided at the top of both sets of mounting columns.

[0014] To facilitate the entry and exit of the compression box, the bottom of the end cover is hinged to the top of any set of mounting columns, and the bottom of another set of mounting columns is provided with a support base that can be separated from the set of mounting columns.

[0015] To facilitate the opening of the end cap, a support beam is connected between the two sets of mounting columns on both sides, and a flip-top cylinder is installed on the support beam. It is located near the mounting column with a support seat, and the output end is slidably and hingedly installed with the bottom end of the end cap.

[0016] To facilitate the connection between the compression box and the tractor and to make it easy to load and unload it onto the lifting platform, the compression box is equipped with towing hooks on two opposite sides in its direction of movement.

[0017] The beneficial effects of this utility model are as follows: This utility model is an underground lifting compression box assembly, which effectively solves the problems of large underground space occupation and high construction cost of traditional underground compression box lifting mechanisms, and significantly improves space utilization and construction convenience. Compared with the defects of scissor-type lifting mechanisms that require increased pit depth, this assembly uses a direct-drive design of multiple lifting cylinders that run through the lifting plate. By using the structure of the outer cylinder of the lifting cylinder being fixed to the lifting plate and the output end being connected to the bottom end of the support component, the lifting plate is directly driven to slide up and down. There is no need to reserve additional space for the lifting mechanism to unfold, which greatly reduces the pit excavation depth, reduces the amount of underground space occupied, and reduces construction difficulty and construction cost. It is more suitable for installation scenarios with dense underground pipelines and limited space in cities.

[0018] In terms of waste processing efficiency and operational stability, the rollers at the bottom of the compression box work in conjunction with the slots on the lifting plate to precisely limit the compression box, preventing it from tilting or shifting during loading and unloading, ensuring easy entry and exit from the lifting frame. The rollers also reduce movement resistance and ensure the compression box is positioned in the center of the lifting frame, guaranteeing balanced force on the lifting mechanism and extending its service life. Combined with the traction hook, the compression box can be easily towed and transported, solving the problem of inconvenient loading and unloading in traditional equipment. The guide wheels at the bottom of the lifting plate are connected to the support column, further improving the stability of the lifting process, preventing waste from scattering due to shaking, reducing subsequent cleaning burden, and ensuring the structural stability of the equipment for long-term use.

[0026] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background section, some existing underground compression boxes 1 are directly fixed below ground, only able to transport and dispose of garbage, which is not very flexible. Others are designed with a lifting mechanism to drive the compression box to the ground, but there are still some drawbacks. On the one hand, the lifting mechanism tends to occupy a lot of underground space. On the other hand, the compression box is very prone to deviation when entering and exiting the lifting mechanism, which can easily cause an imbalance in the force on the lifting mechanism, making it difficult to enter and exit and damaging the lifting mechanism. Therefore, the inventors have made improvements on the existing underground compression boxes and designed a new type of compression box assembly, which will be described in detail below with reference to the figures.

[0029] This embodiment provides an underground lifting compression box assembly, aiming to solve the problems of existing underground compression box 1 lifting mechanisms occupying large underground space, easy scattering of garbage during dumping, and easy tilting of the box body during loading and unloading. Through innovative design of a direct-drive lifting structure, limit guide components, and a flip-top protection system, it achieves efficient lifting, stable loading and unloading, and centralized garbage processing of the compression box 1, adapting to the needs of underground garbage collection and transportation in urban environmental management. For its specific structure, please refer to... Figure 1 This assembly uses an underground support component as its basic load-bearing frame. The support component is fixedly installed in an underground pit and is constructed entirely of high-strength steel, providing sufficient resistance to settlement and impact. The support component includes a horizontally positioned base 6, which is a rectangular frame structure fixed to the concrete foundation at the bottom of the pit to ensure no displacement during long-term use. Four vertical columns 7 are welded to the four corners of the upper surface of the base 6. The columns 7 are rectangular steel pipes with smooth outer walls. The four columns 7 enclose a rectangular lifting space, and the lifting plate 2 is slidably positioned between the four columns 7, moving up and down along the columns 7 to provide support and a lifting platform for the compression box 1.

[0030] In this embodiment, the lifting plate 2 is a rectangular steel plate adapted to the space enclosed by the column 7. Multiple mounting brackets 8 are evenly welded to its bottom edge, and guide wheels 9 are mounted on its bottom end via bearings. The wheel surfaces of the guide wheels 9 contact the outer wall of the column 7 and can roll along the column 7. When the lifting plate 2 rises or falls, the guide wheels 9 roll along the outer wall of the column 7, reducing the frictional resistance between the lifting plate 2 and the column 7, making the lifting smoother, and limiting the lateral displacement of the lifting plate 2, preventing tilting during lifting and ensuring that the compression box 1 remains horizontal. Multiple lifting cylinders 3, preferably four, are evenly arranged through the lifting plate 2, located near the four corners of the lifting plate 2. The lifting cylinders 3 are hydraulically driven, with their output ends facing downwards and fixed to the base 6. The outer cylinder is fixed to the bottom of the lifting plate 2 via flanges. Compared to traditional scissor-type lifting mechanisms, the direct-drive lifting cylinder 3 eliminates the need for complex linkage structures, significantly reducing the overall height of the assembly, decreasing the pit excavation depth, and significantly reducing construction costs and difficulty.

[0031] Based on the above structure, combined with Figure 2The compression box 1 is a rectangular box for storing and compressing waste. One side of the box has a waste inlet, and the other side has a discharge outlet. It is equipped with a waste pushing mechanism, which can be a telescopic cylinder and a scraper, and will not be described in detail here. Four rollers 4 are mounted on the four corners of the bottom of the compression box 1 via brackets. These rollers 4 are arranged in a rectangle, allowing the compression box 1 to move flexibly on the lifting plate 2 for easy loading, unloading, and transfer. Corresponding to the rollers 4, the upper surface of the lifting plate 2 has two parallel strip-shaped grooves 5. These grooves 5 are rectangular recesses, and their spacing is consistent with the distance between the two rollers 4 in the width direction of the compression box 1, ensuring that the rollers 4 in the width direction can accurately fit into the strip-shaped grooves 5 when the compression box 1 is placed. The length of the strip-shaped grooves 5 is not less than the distance between the two rollers 4 in the length direction of the compression box 1, providing sufficient space for the compression box 1 to move back and forth on the lifting plate 2. Furthermore, the two strip-shaped grooves 5 are symmetrically arranged with respect to the midpoint of the lifting plate 2 in the length direction, ensuring balanced force on the compression box 1 and preventing unilateral offset. The setting of the strip groove 5 can not only limit the roller 4 to prevent the compression box 1 from sliding laterally during lifting or transfer, but also guide the compression box 1 to accurately enter the designated position of the lifting plate 2, solving the problem that the traditional compression box 1 is difficult to enter the lifting frame conveniently.

[0032] In this scheme, combined with Figure 3 To prevent garbage from scattering into the pit during dumping, two sets of mounting columns 10 are installed parallel to each other on the upper edge of the lifting plate 2. Each set has multiple columns, and the tops of the two sets of mounting columns 10 jointly support an end cover 11. The end cover 11 is a rectangular cover plate adapted to the area of ​​the lifting plate 2, which can cover the space above the lifting plate 2 to prevent garbage from scattering. The bottom of the end cover 11 is hinged to the top of one set of mounting columns 10, and can be flipped around the hinge. The top of the other set of mounting columns 10 is welded to a support base 12, and the unhinged side of the end cover 11 can be placed on the support base 12 to achieve horizontal fixation. When it is necessary to dump garbage into the compression box 1 or transfer the compression box 1, the end cover 11 can be flipped open around the hinge; after the garbage is dumped or the compression box 1 is fixed, the end cover 11 is flipped back to horizontal and placed on the support base 12 to form a closed protection.

[0033] To reduce the difficulty of flipping the end cap 11, a horizontal support beam 13 is welded between the two sets of mounting posts 10 on both sides. A flip-cap cylinder 14 is mounted on the support beam 13 via a hinge seat. The flip-cap cylinder 14 is positioned close to the mounting post 10 with the support seat 12. The top of its output end is slidably connected to the bottom end of the end cap 11 via a slider. A horizontal groove is welded to the bottom end of the end cap 11, and the slider is embedded in the groove and can slide along the groove. When the piston rod of the flip-cap cylinder 14 extends, it can push the end cap 11 to flip open around the hinge point; when the piston rod retracts, it can pull the end cap 11 to flip and close, realizing the automatic flipping of the end cap 11 without the need for manual operation, thus improving ease of use.

[0034] In addition, the compression box 1 is equipped with traction hooks 15 on its two opposite sides along its direction of movement (i.e., along the length of the strip groove 5), which can cooperate with the hooks of the traction equipment. When it is necessary to pull the compression box 1 off the lifting plate 2 for transfer, the hooks of the traction equipment are connected to the traction hooks 15 on the side of the compression box 1, so that the compression box 1 can be pulled smoothly along the direction of the strip groove 5, avoiding deviation or tilting during the pulling process; when reloading, the compression box 1 can also be guided precisely back to the designated position on the lifting plate 2 along the strip groove 5 by the traction equipment, further improving loading and unloading efficiency.
