Description
Technical Field
[0001] This invention relates to a fully automatic hoisting garbage truck, belonging to the field of sanitation equipment technology. Background Technology
[0002] The current process of collecting garbage using a crane-type garbage truck is as follows: The vehicle is parked at a suitable distance from the underground bin. The operator lowers the outriggers of the crane. After the boom of the folding crane is adjusted and extended, the boom is positioned towards the underground bin. The operator then uses a chain to connect the hook and the underground bin. Once the connection is secure, the crane lifts the underground bin out of the pit. The crane adjusts its luffing and slewing to place the underground bin above the loading port on the truck body. The operator uses ropes to pull the bottom cover of the underground bin to dispose of the garbage. After disposing of the garbage, the crane places the underground bin on the ground. The underground bin closes its bottom cover under its own weight. The operator tidies up the ropes, and then the crane lifts the underground bin back into the pit. The operator disconnects the chain connecting the underground bin, and the crane retracts its extended boom and then retracts the folding boom in the reverse luffing sequence. This operation requires operators to be familiar with the operation of a folding boom crane and to flexibly adapt to different lifting conditions. It also necessitates manual chain attachment between the crane hook and the underground garbage bin. The bins, filled with household waste, emit a strong odor, creating a harsh working environment. The entire operation requires two workers: one to operate the crane and the other to attach and detach the ropes, ensuring the bottom cover of the underground garbage bin is completely closed. The waste collection process is inefficient, and the crane operation is complex due to the multiple lifting and lowering steps involving the underground garbage bin. The operators face a harsh working environment when attaching and detaching the chains. This waste collection and transfer method requires specialized crane operation training, is complex and tedious, and involves high labor intensity. Operators must be in close proximity to the underground garbage bins to attach the lifting ropes, resulting in a harsh working environment, high labor intensity, and safety hazards, severely hindering the market development of this series of crane-type garbage trucks.
[0003] Chinese patent application CN114604781A discloses a vertical lifting mechanism, a lifting vehicle, and a control method. It uses a vertical folding arm crane instead of a traditional folding arm crane, which greatly simplifies crane operation. At the same time, a grabbing device is installed on the crane boom to cooperate with the underground garbage bin to grab the bin and open and close the bottom of the bin. This realizes automatic grabbing of the underground garbage bin and opening and closing of the bottom of the bin, which simplifies crane operation, reduces labor intensity, and lays the foundation for automatic control of lifting garbage trucks. However, the specific implementation details of each functional module are not disclosed.
[0004] To further address the problems of traditional hoisting garbage trucks, such as complex crane operation, harsh working environment when attaching to buried garbage bins, and low work efficiency, there is an urgent need for a fully automatic hoisting garbage truck to achieve intelligent and automated upgrades, improve the working environment, and increase work efficiency.

[0029] See Figures 1-8 This invention relates to a fully automatic hoisting garbage truck, comprising a truck-mounted crane 2 and a garbage container 5 installed on the hoisting garbage truck 1, and a gripping mechanism 3 installed at the end of the lifting arm of the truck-mounted crane 2; it requires a special underground garbage bin 4 to cooperate with the gripping mechanism 3 to achieve automatic gripping operation. Specifically, the underground garbage bin 4 is provided with an upper gripper head 4-1 and a lower gripper head 4-2; the upper gripper head 4-1 is used to perform the opening and closing function of the bottom cover of the underground garbage bin 4; the lower gripper head 4-2 is used to perform the lifting function of the underground garbage bin 4.
[0030] The gripping mechanism 3 includes a connecting seat 3-1 connected to the front end of the boom of the truck-mounted crane 2, a monitoring device 3-2 installed in the middle of the connecting seat 3-1, a gripping mechanism housing 3-3 connected by a connector, a gripper 3-7 mounted on the gripping mechanism housing 3-3 by a lifting cylinder 3-6 vertically mounted on the connecting seat 3-1, an upper gripper 3-8 mounted on the gripper 3-7, and a lower gripper 3-9 mounted on the gripping mechanism housing 3-3.

The monitoring device 3-2 is used to monitor the status of the gripper head of the underground garbage bin 4 at the bottom of the gripping mechanism 3 and transmit the real-time image to the control platform to achieve automatic positioning.
[0031] The upper gripper 3-8 and lower gripper 3-9 are driven to move by the locking mechanism 3-4 and the locking cylinder 3-5, so that the upper gripper 3-8 grabs the upper gripper head 4-1 on the underground barrel 4 to control the opening and closing of the bottom cover, and the lower gripper 3-9 grabs the lower gripper head 4-2 on the underground barrel 4 to control the lifting. The locking mechanism 3-4 includes a force transmission link 3-4-1, an I-type link 3-4-2, and an L-type link 3-4-3.

[0034] The truck-mounted crane 2 is a vertical articulated boom crane, comprising a base assembly 2-2 fixed to the chassis beam of the lifting garbage truck 1, outrigger assemblies 2-1 on both sides of the base assembly 2-2, a slewing mechanism assembly 2-3 rotatably mounted on the base assembly 2-2, a turntable assembly 2-4 mounted on the slewing mechanism assembly 2-3, and an outer boom assembly 2-5 hinged to the turntable assembly 2-4 via a luffing cylinder 2-6 and a hinge point. The outrigger assembly 2-1 provides stable support for the vertical articulated boom truck-mounted crane 2 during operation; the slewing mechanism assembly 2-3 provides the overall slewing motion of the crane; the turntable assembly 2-4 includes a three-stage telescopic mechanism for height adjustment of the lifted object; the outer boom assembly 2-5 includes a three-stage telescopic mechanism for adjusting the working radius of the lifted object; and the luffing cylinder 2-6 connects the turntable assembly 2-4 and the outer boom assembly 2-5 to control the working radius of the outer boom assembly 2-5.
[0035] The vehicle-mounted garbage bin 5 includes a body 5-3 mounted on the chassis of the hoisting garbage truck 1, a feeding port 5-1 at the front of the body 5-3, a push plate 5-2 inside the body 5-3, and a rear door 5-4 at the rear of the body 5-3; the feeding port 5-1 is used to receive domestic waste from the underground bin 4, and the push plate 5-2 is used to compress the waste.
[0036] The operation process of the fully automatic hoisting garbage truck of this invention is as follows: After the vehicle stops, the outrigger assembly 2-1 of the vertical folding boom truck-mounted crane 2 extends to support the ground, and the telescopic mechanism of the turntable assembly 2-4 extends vertically. Driven by the slewing mechanism assembly 2-3, the outer boom assembly 2-5, the luffing cylinder 2-6, and the grabbing mechanism 3 move towards the underground bin 4. Then, the grabbing mechanism 3 extends above the underground bin 4 under the drive of the telescopic mechanism of the outer boom assembly 2-5 and the luffing cylinder 2-6. The grabbing mechanism 3 aligns with the upper grab head 4-1. The monitoring device 3-2 transmits the real-time image of the lower part of the grabbing mechanism 3 to the control platform to improve the positioning speed and positioning accuracy. When the inner surface of the top plate 3-9-1 of the lower locking plate 3-9 is pressed against the outer surface of the underground barrel lifting grab 4-2, and simultaneously the inner surface of the upper cover plate of the grabbing mechanism 3 grab 3-7 is pressed against the upper surface of the underground barrel lifting grab 4-1, the pre-grab is completed; then the locking cylinder 3-5 is activated, driving the locking mechanism 3-4 to move downward, causing the upper gripper 3-8 and lower gripper 3-9 to lock the upper grab 4-1 and lower grab 4-2 of the underground barrel 4, completing the automatic grab; the lifting cylinder 3-6 moves upward, grabbing... Hand 3-7 drives the upper grab head 4-1 to move upward, locking the bottom cover of the underground bin 4 to prevent garbage leakage during hoisting; then the crane 2 drives the grabbing mechanism 3 to lift and rise. As the lifting height increases, the lower gripper 3-9 contacts the lower surface of the lower grab head 4-2 and places the entire underground bin 4 above the feeding port 5-1. The lifting cylinder 3-6 extends, driving the grab hand 3-7 to move downward, which in turn drives the upper grab head 4-1 to move downward, thereby driving the bottom cover of the underground bin 4 to open for feeding.
[0037] After feeding, the push plate 5-2 of the vehicle-mounted container 5 pushes the garbage into the container 5-3. With the locking and sealing of the rear door 5-4, the garbage is pushed and compressed. At this time, the grabbing mechanism 3 completes the closing operation of the bottom cover of the underground bin 4. Then, the truck-mounted crane 2 sends the underground bin 4 into the pit. The lifting cylinder 3-6 of the grabbing mechanism 3 drives the grabber 3-7 and the upper gripper 3-8 to move downward. The upper gripper 3-8 drives the upper grab head 4-1 of the underground bin 4 to move downward. After moving downward, the locking cylinder 3-5 drives the locking mechanism 3-4 to move upward, causing the upper gripper 3-8 and the lower gripper 3-9 to open. At the same time, it drives the grabbing mechanism 3 to move upward, completing the automatic separation of the grabbing mechanism. The bottom cover is kept closed by the weight of the underground bin 4. Then, the crane 2 retracts the telescopic mechanism of the outer arm assembly 2-5 and the turntable assembly 2-4 and rotates back to the position. Finally, the outrigger assembly 2-1 is retracted, completing one feeding operation.
[0038] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
