Description

Technical Field

[0001] This invention relates to the field of waste transfer technology, and in particular to a lifting telescopic arm type waste transfer device. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of urban infrastructure, underground facilities such as buried sewage pumping stations and underground garbage transfer stations are widely used. These underground facilities generate a certain amount of waste during operation, requiring regular collection by garbage trucks. However, due to the height difference between the underground space and the ground surface, how to efficiently and safely lift the waste from underground to the surface and smoothly transfer it to garbage trucks has become a pressing technical problem. Furthermore, these underground facilities are usually located in urban public landscape areas, requiring a high degree of integrity in the surface landscape; the transfer equipment must be harmonious with the surrounding environment when not in operation to avoid disrupting the aesthetic appeal.

[0003] Currently, most existing underground waste transfer systems use fixed lifting frames or simple hoisting equipment. The waste containers are vertically lifted to the ground using wire ropes or chains, and then manually or with auxiliary equipment, the containers are pushed to the vicinity of the garbage truck for unloading. Some improved systems use a single rotating arm structure, utilizing hydraulic cylinders to drive the arm's swing to achieve horizontal displacement of the waste container. These systems often employ a monolithic design, lacking coordination between functional modules. Lifting, rotating, and extending movements often require multiple independent power sources for control, resulting in low system integration.

[0004] However, the traditional vertical lifting and horizontal pushing method in the prior art not only occupies a lot of space, but also has a complicated operation process and makes it difficult to achieve precise alignment between the garbage bin and the garbage truck. Especially when there is a deviation in the parking position of the garbage truck, it is necessary to make repeated adjustments, which affects the operation efficiency. Therefore, this application proposes a lifting telescopic arm type garbage transfer device. Summary of the Invention

[0005] The purpose of this invention is to address the problems of large space occupation, cumbersome operation process, and difficulty in achieving precise alignment between garbage bins and garbage truck compartments in the prior art, and to propose a lifting telescopic arm type garbage transfer device.

[0006] The technical solution of the present invention: a lifting telescopic arm type garbage transfer device, including a lifting platform, a support frame installed on the upper surface of the lifting platform, and a bearing seat installed on one side inside the support frame; the garbage transfer device also includes a rotation adjustment mechanism disposed above the bearing seat; The rotation adjustment mechanism includes a toothed plate mounted on the top of the bearing seat, and a motor is mounted on one side of the outer wall of the support frame. A drive wheel is mounted on the output end of the motor, and the toothed plate meshes with the drive wheel. The waste transfer device also includes a waste positioning mechanism disposed above the toothed plate. The waste positioning mechanism includes an inclined column mounted on the upper surface of a toothed plate. A mechanical arm is rotatably mounted on one end of the inclined column. An electric push rod is positioned between the mechanical arm and the inclined column. A middle extension arm is slidably mounted at the end of the mechanical arm. An end extension arm is slidably mounted at the end of the middle extension arm. An electric push rod is mounted on the upper surface of the mechanical arm, and the output end of the electric push rod is fixedly connected to the end of the end extension arm. A waste bin is mounted on the lower surface of the end extension arm.

[0007] Optionally, guide posts are installed on both sides of the outer wall of the middle extension arm and the end extension arm, and multiple guide posts are slidably disposed inside the robotic arm.

[0008] Optionally, one end of the electric push rod is hinged to the lower side of the outer wall of the inclined column and the middle of the outer wall of the robotic arm via an adapter shaft.

[0009] Optionally, a power control mechanism is installed on the upper surface of the lifting platform near the support frame. The power control mechanism is electrically connected to the motor, electric push rod one, electric push rod two, and electric push rod three, respectively.

[0010] Optionally, the garbage bin is detachably connected to the end of the end extension arm, and the bottom of the garbage bin is provided with an automatically opening and closing unloading door.

[0011] Optionally, the lifting platform is equipped with mounting plates at both ends, and U-shaped sliding plates are installed at both ends of the mounting plates. The U-shaped sliding plates are connected to each other by I-beams.

[0012] Optionally, the waste transfer mechanism may also include a platform lifting mechanism located below the I-beam frame; The platform lifting mechanism includes a support base and an electric push rod three, with the electric push rod three installed on one side of the outer wall of the support base and the output end of the electric push rod three installed on the lower surface of the I-beam frame.

[0013] Optionally, the inner wall of the U-shaped slide plate is slidably disposed on one side of the outer wall of the support base, and the U-shaped groove portion of the U-shaped slide plate matches the outer wall of the support base.

[0014] Optionally, a support column is installed on the upper surface of each of the four top corners of the lifting platform, and a grass planting platform is installed on the top of the support column.

[0015] Optionally, the grass planting platform is flush with the upper surface of the lifting platform.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention, by setting up a rotation adjustment mechanism and a multi-stage telescopic garbage positioning mechanism, achieves precise rotational alignment of the garbage bin in the horizontal direction and a wide range of telescopic adjustment in the horizontal direction. It can flexibly adapt to garbage transfer vehicles at different parking positions, ensure precise alignment between the garbage bin and the vehicle compartment, and significantly improve the automation level and work efficiency of garbage transfer operations.

[0017] Furthermore, by setting up a platform lifting mechanism driven by three electric push rods, and in conjunction with the sliding guide structure between the U-shaped slide plate and the support base, the overall smooth lifting of the lifting platform is achieved. In the non-working state, the grass planting platform is supported to be flush with the ground by the support columns. This not only meets the operational requirements of the underground waste transfer device, but also ensures the integrity and restoreability of the ground landscape. It has the characteristics of compact structure, stable operation and strong concealment. Attached Figure Description

[0020] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] Example 1 like Figures 1-3 As shown, the present invention proposes a lifting telescopic arm type garbage transfer device, including a lifting platform 1, a rotation adjustment mechanism disposed above a bearing seat 3, and a garbage positioning mechanism disposed above a toothed plate 4; a support frame 2 is installed on the upper surface of the lifting platform 1, and a bearing seat 3 is installed on one side inside the support frame 2; the rotation adjustment mechanism includes a toothed plate 4 installed on the top of the bearing seat 3, and a motor 5 is installed on one side of the outer wall of the support frame 2, and a drive wheel 6 is installed at the output end of the motor 5, and the toothed plate 4 meshes with the drive wheel 6; The garbage positioning mechanism includes an inclined column 7 installed on the upper surface of the toothed plate 4. A mechanical arm 8 is rotatably mounted on one end of the inclined column 7. An electric push rod 9 is installed between the mechanical arm 8 and the inclined column 7. A middle extension arm 11 is slidably mounted on the end of the mechanical arm 8. An end extension arm 12 is slidably mounted on the end of the middle extension arm 11. An electric push rod 10 is mounted on the upper surface of the mechanical arm 8. The output end of the electric push rod 10 is fixedly connected to the end of the end extension arm 12. A garbage bin 14 is mounted on the lower surface of the end extension arm 12. In this embodiment, guide columns 13 are installed on both sides of the outer wall of the middle extension arm 11 and the end extension arm 12, and multiple guide columns 13 are slidably arranged inside the robotic arm 8; the two ends of the electric push rod 9 are respectively hinged to the lower side of the outer wall of the inclined column 7 and the middle of the outer wall of the robotic arm 8 through the adapter shaft; a power control mechanism 22 is installed on the upper surface of the lifting platform 1 near the support frame 2, and the power control mechanism 22 is electrically connected to the motor 5, electric push rod 9, electric push rod 10 and electric push rod 19 respectively; the garbage bin 14 is detachably connected to the end of the end extension arm 12, and the bottom of the garbage bin 14 is provided with an automatically opening and closing unloading door. The garbage positioning mechanism and the rotation adjustment mechanism are described in detail below: In this embodiment, the lifting telescopic arm garbage transfer device is initially positioned with the lifting platform 1 located on the first basement level, in a standby state. When the garbage truck arrives at the designated location, the lifting platform 1 is moved above ground via the platform lifting mechanism. Then, the power control mechanism 22 receives a start signal and first starts the motor 5. The output of the motor 5 drives the drive wheel 6 to rotate. Since the drive wheel 6 meshes with the toothed plate 4, the toothed plate 4, under the driving force of this meshing, drives the inclined column 7 and all components above it to rotate horizontally around the axis of the bearing seat 3. The rotation angle can be preset according to the parking position of the garbage truck, typically 90 degrees, aligning the working direction of the robotic arm 8 with the axis of the garbage truck compartment, thus achieving precise positioning of the garbage transfer direction.

[0022] After directional alignment is completed, the power control mechanism 22 activates the electric push rod 9. The two ends of the electric push rod 9 are hinged to the lower outer wall of the inclined column 7 and the middle of the outer wall of the robotic arm 8, respectively. When the push rod of the electric push rod 9 extends, the robotic arm 8 rises upwards around its rotational connection point with the inclined column 7, thereby adjusting the elevation angle of the robotic arm 8. The adjustment range of the elevation angle is preset according to the required lifting height of the garbage bin 14 and the height of the garbage truck compartment, ensuring that the garbage bin 14 can be lifted to a suitable unloading height.

[0023] Once the robotic arm 8 is raised to the preset height, the power control mechanism 22 activates the electric push rod 10. The electric push rod 10 is fixedly mounted on the upper surface of the robotic arm 8, and its output end is fixedly connected to the end of the end extension arm 12. When the electric push rod 10 extends, it first pushes the end extension arm 12 to slide outward along the inside of the middle extension arm 11. After the end extension arm 12 slides to its limit position, it continues to push the middle extension arm 11 to slide outward along the inside of the robotic arm 8. Guide posts 13 are installed on both sides of the outer wall of the middle extension arm 11 and the end extension arm 12. The guide posts 13 are slidably positioned in grooves opened inside the robotic arm 8, providing stable guidance during the extension and retraction process and preventing swaying. The garbage bin 14 is smoothly pushed directly above the garbage truck compartment, achieving precise horizontal alignment.

[0024] After the garbage bin 14 reaches the unloading position, the power control mechanism 22 controls the automatic opening and closing unloading door at the bottom of the garbage bin 14 to open, and the garbage falls into the garbage transfer vehicle compartment under the action of gravity, completing the unloading. After unloading, the power control mechanism 22 controls the electric push rod 10 to retract in sequence, so that the middle extension arm 11 and the end extension arm 12 are retracted into the mechanical arm 8 in sequence; then it controls the electric push rod 9 to retract, so that the mechanical arm 8 is lowered to the initial height; finally, it controls the motor 5 to rotate in the opposite direction, so that the toothed plate 4 drives the inclined column 7 and its upper components to rotate back to the initial direction, completing a complete garbage transfer cycle.

[0025] Example 2 like Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, the waste transfer device also includes a platform lifting mechanism located below the I-beam frame 16; both ends of the lifting platform 1 are equipped with mounting plates 15, and both ends of the mounting plates 15 are equipped with U-shaped sliding plates 17, which are connected to each other through the I-beam frame 16. The platform lifting mechanism includes a support base 18 and an electric push rod 19. The electric push rod 19 is installed on one side of the outer wall of the support base 18, and its output end is installed on the lower surface of the I-beam frame 16. The inner wall of the U-shaped sliding plate 17 is slidably disposed on one side of the outer wall of the support base 18, and the U-shaped groove of the U-shaped sliding plate 17 matches the outer wall of the support base 18. A support column 20 is installed on the upper surface of each of the four top corners of the lifting platform 1, and a grass planting platform 21 is installed on the top of the support column 20. The grass planting platform 21 is flush with the upper surface of the lifting platform 1. The platform lifting mechanism is described in detail below: In this embodiment, when the device is not in operation, the lifting platform 1 is located on the first basement level. The grass planting platform 21 is supported on the upper surface of the lifting platform 1 by the support column 20. The upper surface of the grass planting platform 21 is flush with the ground, maintaining the integrity and aesthetics of the ground landscape. When garbage transfer operations are required, the power control mechanism 22 receives the start signal and first activates the electric push rod 19.

[0026] The fixed end of the electric actuator 19 is installed on one side of the outer wall of the support base 18, and its output end is fixedly connected to the lower surface of the I-beam 16. The support base 18 is fixedly installed on the foundation of the first basement level, serving as the load-bearing foundation for the entire device. After the electric actuator 19 is started, its output end extends upward, pushing the I-beam 16 upward. The two ends of the I-beam 16 are fixedly connected to the U-shaped sliding plate 17 through the mounting plate 15. The inner wall of the U-shaped sliding plate 17 slides against both sides of the outer wall of the support base 18, and the U-shaped groove of the U-shaped sliding plate 17 matches the outer wall of the support base 18, forming a stable sliding guide structure. Under the continuous pushing of the electric actuator 19, the I-beam 16 drives the mounting plate 15 and the U-shaped sliding plate 17 to rise smoothly along the outer wall of the support base 18.

[0027] Mounting plates 15 are fixedly connected to both ends of the lifting platform 1, so the lifting platform 1 rises synchronously with the mounting plates 15. During the rising process, the lifting platform 1 drives the grass planting platform 21 to rise synchronously through the support columns 20, so that the grass planting platform 21 gradually rises above the ground. When the lifting platform 1 rises to the preset working height, the electric push rod 19 stops moving. At this time, the lifting platform 1 and the rotation adjustment mechanism and garbage positioning mechanism installed above it are completely exposed above the ground, which facilitates garbage grabbing and transfer operations.

[0028] After the waste transfer operation is completed, the power control mechanism 22 controls the output end of the electric push rod 19 to retract, causing the I-beam frame 16, mounting plate 15, U-shaped sliding plate 17, and lifting platform 1 to descend smoothly as a whole. During the descent, the U-shaped sliding plate 17 slides along the outer wall of the support base 18 to ensure the verticality and stability of the descent path of the lifting platform 1 and prevent tilting. When the lifting platform 1 descends to the initial position, the upper surface of the grass planting platform 21 is flush with the ground again, restoring the landscape setup.

[0029] Through the sliding cooperation between the electric push rod 19, the U-shaped sliding plate 17, and the support seat 18, the lifting platform 1 can be lifted and positioned smoothly and accurately. This not only meets the operational requirements of the underground waste transfer device, but also ensures the integrity and restoreability of the ground landscape. It features a compact structure, stable operation, and strong concealment.

[0030] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
