[0002] In hazardous waste landfills, concrete covers are required to seal the landfill when the landfill unit reaches its top. However, these covers are typically rectangular, making it difficult to align them directly with the landfill unit during hoisting. Traditionally, the cover is lowered and its angle manually adjusted, or the position of a mobile hoisting device is manually adjusted to change the angle between the cover and the landfill unit.

[0011] Furthermore, the support mechanism also includes a support column, and one end of the load-bearing telescopic rod away from the telescopic end is hinged to the support column.

[0012] Beneficial effects:

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] The hoisting mechanism is rotatably mounted on the support mechanism. It can rotate around the hoisting points of both mechanisms, pressing against them.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 4 A landfill cover hoisting device includes a support mechanism 1 and a hoisting mechanism 3, wherein the hoisting mechanism 3 is rotatably mounted on the support mechanism 1 and has a first direction and a second direction.

[0024] The hoisting mechanism 3 includes a drive source 32, which is detachably connected to the cover plate 5. The cover plate 5 has a first position and a second position relative to the support mechanism 1. The cover plate 5 of the hoisting mechanism 3 located in the first direction is in the first position and is flush with the support mechanism 1. When the hoisting mechanism 3 located in the first direction rotates to the second direction, the drive source 32 drives the cover plate 5 to rotate from the first position to the second position. The cover plate 5 is used to align with the landfill unit 2 covering the landfill site.

[0025] In this technical solution, the hoisting mechanism 3 is rotatably mounted on the support mechanism 1. The hoisting mechanism 3 can press against the support mechanism 1 and the hoisting point of the hoisting mechanism 3 to perform a circular motion. When the hoisting mechanism 3 is in the first direction, it is folded next to the support mechanism 1 for easy hanging of the cover plate 5. When the hoisting mechanism 3 rotates from the first direction to the second direction, it is positioned above the landfill unit 2. Then, the drive source 32 rotates to adjust the position of the cover plate 5. When the hoisting mechanism 3 is in the first direction, the drive source 32 drives the cover plate 5 to move from the second position to the first position, making the cover plate 5 flush with the support mechanism 1 for easy storage and organization. This is the first adjustment state. Figure 3 As shown, it does not occupy space; when the hoisting mechanism 3 is in the second direction, the drive source 32 drives the cover plate 5 to move from the first position to the second position. This is the second adjustment state, which has the function of... Figure 2 As shown, the cover plate 5 can be aligned with the landfill unit 2 and is placed on the landfill unit 2. Through the coordinated operation of the support mechanism 1 and the hoisting mechanism 3, and with the precise control of the position of the cover plate 5 by the drive source 32, the cover plate 5 can be quickly placed on the landfill unit 2. This avoids the manual adjustment method used in the prior art, greatly reduces the automated rotation and positioning process, improves work efficiency, saves time and costs, and speeds up the project progress.

[0026] The assembly relationship between the support mechanism 1 and the hoisting mechanism 3 is as follows: Figure 1 As shown, the support mechanism 1 includes a load-bearing telescopic rod 11, which is a telescopic structure with a telescopic end. The drive source 32 has a first direction and a second direction, and the end of the drive source 32 away from the cover plate 5 is hinged to the telescopic end. The telescopic structure of the load-bearing telescopic rod 11 allows the lifting device to flexibly adjust its overall height according to the height of different landfill units 2 and the spatial limitations of different working environments. Whether it is a shallow landfill unit or a deep landfill area, the cover plate 5 can be smoothly lifted and installed at a suitable position by adjusting the length of the load-bearing telescopic rod 11. Compared with a fixed-height support mechanism, this device greatly expands its application range, improves the versatility of the equipment, reduces the cost and time of equipment replacement due to site conditions, and can meet the operational needs of various landfill projects. The load-bearing telescopic rod 11 has a built-in electro-hydraulic drive system. This system includes a hydraulic cylinder, a hydraulic pump, a motor, and a control valve. The cylinder barrel of the hydraulic cylinder is fixed in the central interior of the load-bearing telescopic rod 11, and the piston rod of the hydraulic cylinder is connected to the outermost telescopic end. The electric motor drives the hydraulic pump, which pressurizes the hydraulic oil and delivers it to the hydraulic cylinder through pipelines. This pushes the piston rod to extend or retract, thereby causing the telescopic end to extend or retract in stages. The flow rate and pressure of the hydraulic oil can be precisely adjusted by the control valve, thereby controlling the extension speed and stroke of the load-bearing telescopic rod 11.

[0027] When the drive source 32 rotates the cover plate 5, the generated torque and centrifugal force are transmitted to the load-bearing telescopic rod 11 through the hinge shaft. Because the hinge structure allows the drive source 32 to rotate within a certain range, these forces can be distributed more rationally on the load-bearing telescopic rod 11, avoiding localized stress concentration. Simultaneously, the multi-stage sleeve structure and robust guiding system of the load-bearing telescopic rod 11 maintain its rigidity and stability when subjected to these external forces, ensuring that the entire lifting device will not sway or tilt during operation, thus improving the safety and reliability of the operation.

[0028] It should be noted that the specific embodiment of the hoisting mechanism 3 is provided by [the relevant authority / organization]. Figure 1 As shown, the lifting mechanism 3 also includes a rotating frame 31 and a transmission assembly. The drive source 32 is connected to the transmission assembly, the transmission assembly is connected to the rotating frame 31, and the rotating frame 31 is connected to the lifting claw 4. The power from the drive source 32 is transmitted to the rotating frame 33 via the transmission assembly, enabling horizontal rotation or multi-angle tilt adjustment of the lifting claw 4. The type of transmission assembly is not limited here, but chain drive is preferred, as it is a conventional technique and will not be elaborated upon further.

[0029] The drive source 32 can be selected as a drive motor, which is hinged to the telescopic end of the load-bearing telescopic rod 11. The drive motor has a pulley, which is connected to the hinge bracket. The hinge bracket and the rotating frame 31 are connected by a pin. In this connection method, the drive motor drives the pulley to move, and the hinge bracket moves accordingly, which drives the rotating frame 31 to rotate. During the hoisting and rotation of the cover plate 5, the force can be effectively dispersed and transmitted.

[0030] The drive source 32 can also be a swing cylinder. The output shaft of the swing cylinder is directly connected to the rotating frame without the need for additional transmission components. The piston inside the swing cylinder drives the rotation of the blades, and the blades drive the rotation of the output shaft, thereby rotating the output angle. The swing cylinder is a conventional technical means and will not be described in detail here.

[0031] As a preferred embodiment, by Figure 1 As shown, it also includes a lifting claw 4. One end of the lifting claw 4 is used to grip the cover plate 5, and the other end of the lifting claw 4 is connected to the drive source 32. The operation of the lifting claw 4 to grip the cover plate 5 is convenient. Specifically, the cover plate 5 is provided with a fixing hook 51, which is detachably connected to the lifting claw 4. The fixing hooks 51 are provided around the cover plate 5. The lifting claw 4 grips the fixing hooks 51 of the cover plate 5 itself, which makes it easy to lift the cover plate 5. The cover plate 5 is not easy to fall off, and the structure is stable.

[0032] It is worth noting that the drive source 32 has a remote control receiving module connected to the rotating frame 31. This module receives signals to control the drive source 32 to rotate the rotating frame 31. In this embodiment, the drive source 32 is equipped with a remote control receiving module connected to the rotating frame 31. Operators do not need to be near the hoisting device; they can remotely control the drive source 32 from a safe location away from the work area by sending control signals via a remote control, thereby rotating the rotating frame 31. Traditional manual operation or close-range mechanical control methods require a distant observation point to observe whether the cover plate is aligned with the landfill opening of the landfill unit 2 when adjusting the angle of the rotating frame 31. However, the operation point for adjusting the angle of the cover plate 5 is close to the landfill unit 2. Therefore, operators often need to frequently travel between the operation point and the observation point, consuming a significant amount of time. The application of the remote control receiving module allows operators to control the drive source 32 in real time and accurately, quickly adjusting the angle and position of the rotating frame 31 without repeated position movements and operation confirmations.

[0033] The drive source 32 includes an angle sensor. Before operation, the angle sensor is installed on the cover plate 5, and the remote control receiving module is connected to the cover plate 5 through the angle sensor. The angle sensor monitors the actual angle of the cover plate in real time and feeds the data back to the remote control receiving module. The user presets the angle of the cover plate 5 at the observation point, and the drive source 32 can automatically adjust the rotating frame according to the preset angle, eliminating errors from manual estimation.

[0034] As a preferred implementation method, by Figure 1 As shown, the support mechanism 1 also includes a support column 12. The end of the load-bearing telescopic rod 11 away from the telescopic end is hinged to the support column 12 to distribute the force on the load-bearing telescopic rod 11, avoid the concentration of stress at a single point, and improve stability. When not in operation, the load-bearing telescopic rod 11 can be folded and stored around the support column 12 to save storage space.

[0035] Depend on Figure 2 and Figure 3As shown, during the landfill cover hoisting operation, firstly, based on the height and position of the landfill unit 2, the electro-hydraulic drive system of the load-bearing telescopic rod 11 is activated via the control system to adjust the telescopic length of the load-bearing telescopic rod 11, so that the drive source 32 and the cover plate 5 are in the first position. Then, the operator controls the drive source 32 to start via remote control, which drives the cover plate 5 to rotate from the first direction to the second direction, so that the cover plate 5 is in the second position, aligned with the top opening of the landfill unit 2. After the cover plate 5 reaches the top opening of the landfill unit 2, the angle of the cover plate 5 is finely adjusted again via remote control to ensure complete alignment. Finally, the cover plate 5 is smoothly lowered and placed on the landfill unit 2. After the operation is completed, the lifting claw 4 and the cover plate 5 are separated, the lifting claw 4 is retracted, and the load-bearing telescopic rod 11 can be retracted as needed for easy movement and storage of the equipment.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
