Description

Technical Field

[0001] This utility model relates to the technical field of underground waste compression stations, specifically to an underground tilting platform lifting assembly. Background Technology

[0002] Underground waste compression stations, as an intensive and environmentally friendly waste collection facility, have been widely used due to their ability to effectively save ground space and improve the community environment. To further increase the waste processing capacity at a single point, existing technologies have developed double-layer underground waste compression stations, in which two waste compression stations are stacked one above the other in an underground pit and share a single lifting mechanism to achieve synchronous lifting and lowering of the two.

[0003] In actual cleaning operations, both the upper and lower levels of the garbage compression station are cleaned by level transport. That is, the compression station, which is moved to be level with the ground, is pulled out of the pit by transport vehicles such as hooklift trucks, transported to the treatment plant for unloading, and then sent back.

[0004] However, when cleaning the upper compression station, it must first be lowered back to the ground. During this time, the entire system cannot receive waste, causing a functional interruption. Cleaning two compression stations means that all hauling operations must be repeated twice. This sequential process results in a long total operation time, low utilization of vehicles and personnel, and severely reduces the turnover and processing capacity of the waste station. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides an underground tilting platform lifting assembly.

[0006] The technical solution of this utility model is as follows: An underground tilting platform lifting assembly is installed in a foundation pit and includes an elongated foundation pit frame. The foundation pit frame is equipped with a lifting mechanism and a support plate assembly. The lifting mechanism includes lifting devices that are inverted and installed at the four corners of the foundation pit frame. The lifting devices include a housing and an extension end, and the extension end is connected to the bottom of the foundation pit frame. The support plate assembly includes a lower support plate and an upper support plate arranged vertically. The lower support plate is arranged horizontally, and the outer side of the lower support plate is connected to the lower part of the housing of multiple lifting devices. The height position of the support plate assembly within the foundation pit frame is adjustable. The lower support plate is equipped with multiple columns that support the upper support plate. The upper support plate is hinged to one side of the column along its length, and the other side is connected to the upper part of the column through an angle adjustment device.

[0007] Preferably, the four corners of the lower support plate are slidably connected to the vertical side frame of the adjacent foundation pit frame via pulley blocks.

[0008] To improve the stability of the columns on the same side, multiple columns are distributed at the four corners of the lower support plate. An inverted triangular frame is provided between adjacent columns on the same side along the length of the foundation pit frame. The triangular frame includes an upper horizontal bar connected end to end and two diagonal bars. The upper horizontal bar is located at the top of the column.

[0009] The specific structure of the angle adjustment device is as follows: the angle adjustment device is a flip-top cylinder, one end of which is hinged to the end of the upper crossbar, and the other end is hinged to the upper support plate.

[0010] Preferably, the upper end face of the lower support plate is provided with at least one auxiliary support leg along its length direction, the upper end of the auxiliary support leg extends upward through the upper crossbar, and the horizontal plane where its upper end face is located is flush with the horizontal plane where the upper end face of the column is located.

[0011] Furthermore, an auxiliary support leg is positioned in the middle of the triangular frame, with its lower end connecting to the lower ends of the two diagonal braces.

[0012] Preferably, the connection between the auxiliary support leg and the upper crossbar is provided with a ring-shaped reinforcing rib.

[0013] Preferably, two adjacent columns on the same side along the width direction of the foundation pit frame are hinged columns, and the column located at one end of the lower support plate and away from the two hinged columns is a support column. The upper end face of the support column is provided with a folded plate in the vertical direction.

[0014] The specific structure of the folded plate is as follows: the folded plate includes an integrally formed vertical plate segment and an inclined plate segment. The vertical plate segment is connected to the upper end face of the supporting column, and the inclined plate segment is inclined outward. The included angle between the vertical plate segment and the inclined plate segment is between 120° and 160°.

[0015] The beneficial effects of this utility model are as follows: By setting up a lower support plate and an upper support plate stacked one on top of the other, and sharing a set of lifting equipment placed upside down at the four corners of the foundation pit frame for driving, a single foundation pit frame structure can accommodate and independently control two waste compression stations, which greatly improves the waste storage and processing capacity per unit area. The integrated design structure is compact, reducing the space occupation and cost caused by multiple independent drive systems. The upper support plate is hinged on one side and tilted controllably via a flip-top cylinder on the other side. This design allows the upper waste compression station to be raised and lowered smoothly, and to be precisely tilted and unloaded at a high position. It utilizes gravity to achieve efficient and thorough removal of waste blocks, avoiding the cumbersome operation and waiting time of traditional hauling methods. At the same time, the lower waste compression station can be stably raised and lowered to the ground via the lower support plate for horizontal hauling. The operation of the upper and lower levels does not interfere with each other, realizing parallel and efficient hauling operations, and eliminating the risk of personnel working at the edge of the pit. The columns distributed at the four corners of the lower support plate are reinforced and connected by an inverted triangular frame, which effectively resists the huge torque and lateral force generated by the tilting unloading of the upper support plate and the bearing of heavy objects, and prevents the columns from deforming. The added auxiliary support legs and their annular reinforcing ribs further disperse the concentrated load, and together with the triangular frame, they form a high-strength three-dimensional support network, ensuring the reliability and durability of the equipment under long-term heavy load conditions.

[0016] The folded plate at the upper end of the support column provides excellent guidance and cushioning during equipment reset, effectively preventing rigid collisions between the upper support plate and its compression station and the column, thus protecting the equipment from damage. This design enhances the system's fault tolerance and extends the service life of critical components. Attached Figure Description

[0018] See Figure 1 and Figure 2 As shown, an underground tiltable platform lifting assembly is installed in a foundation pit and includes an elongated foundation pit frame 1. The foundation pit frame 1 is equipped with a lifting mechanism and a support plate assembly. The lifting mechanism includes lifting devices 2 inverted and installed at the four corners inside the foundation pit frame 1. The lifting devices 2 include a housing 201 and an extension end 202, and the extension end 202 is connected to the bottom of the foundation pit frame 1.

[0019] The support plate assembly includes a lower support plate 3 and an upper support plate 4 arranged vertically. The lower support plate 3 is arranged horizontally, and the outer side of the lower support plate 3 is connected to the lower part of the housing 201 of multiple lifting devices 2 respectively. The four corners of the lower support plate 3 are slidably connected to the vertical side frame of the adjacent foundation pit frame 1 through pulley group 12. The height position of the support plate assembly within the foundation pit frame 1 is adjustable.

[0020] The lower support plate 3 is equipped with multiple columns supporting the upper support plate 4. One side of the upper support plate 4 is hinged to the column along its length, and the other side is connected to the upper part of the column through an angle adjustment device. To improve the stability of the columns on the same side, multiple columns are distributed at the four corners of the lower support plate 3. An inverted triangular frame 7 is provided between adjacent columns on the same side along the length of the foundation pit frame 1. The triangular frame 7 includes an upper horizontal bar 701 connected end to end and two diagonal bars 702. The upper horizontal bar 701 is located at the upper part of the column. The columns distributed at the four corners of the lower support plate 3 are reinforced and connected by the inverted triangular frame 7, which effectively resists the huge torque and lateral force generated by the tilting unloading and bearing heavy objects of the upper support plate 4, and prevents the columns from deforming.

[0021] In this embodiment, the angle adjustment device is a flip-top cylinder 8. One end of the flip-top cylinder 8 is hinged to the end of the upper crossbar 701, and the other end is hinged to the upper support plate 4. Two flip-top cylinders 8 can be symmetrically arranged. When the garbage compression station on the upper support plate 4 needs to unload, the lifting mechanism raises the upper support plate 4 above the ground. By controlling the action of the flip-top cylinder 8, one side of the upper support plate 4 is rotated upward, so that the garbage compression station on it can directly unload to the garbage truck located on the ground. There is no need to drag the garbage compression station on the upper support plate 4 out of the pit by a hook-lift truck and then clean it. Precise tipping and unloading can be achieved at a high position. The efficient and thorough removal of garbage blocks is achieved by using gravity, avoiding the cumbersome operation and waiting time of traditional hauling methods.

[0022] The upper end face of the lower support plate 3 is provided with at least one auxiliary support leg 9 along its length. The upper end of the auxiliary support leg 9 extends upward through the upper crossbar 701, and the horizontal plane of its upper end face is flush with the horizontal plane of the upper end face of the column. One auxiliary support leg 9 is located in the middle of the triangular frame 7, and its lower end is connected to the lower ends of the two diagonal bars 702. A ring-shaped reinforcing rib 10 is provided at the connection between the auxiliary support leg 9 and the upper crossbar 701.

[0023] See Figure 3 and Figure 4 As shown, two adjacent columns on the same side along the width of the foundation pit frame 1 are hinged columns 5. A column located at one end of the lower support plate 3 and away from the two hinged columns 5 is a support column 6. The upper end face of the support column 6 is provided with a folded plate 11 along the vertical direction. The folded plate 11 includes an integrally formed vertical plate segment 1101 and an inclined plate segment 1102. The vertical plate segment 1101 is connected to the upper end face of the support column 6, and the inclined plate segment 1102 is inclined outwards. The included angle between the vertical plate segment 1101 and the inclined plate segment 1102 is between 120° and 160°. The folded plate 11 at the upper end of the support column 6 plays a good guiding and buffering role during equipment resetting, effectively preventing rigid collisions between the upper support plate 4 and its compression station and the column, protecting the equipment from damage. This design enhances the system's fault tolerance and extends the service life of key components.
