Description

Technical Field

[0001] The utility model relates to a rotary guardrail unloading mechanism, belonging to the technical field of guardrail production unloading structure improvement. Background Art

[0002] Road guardrails play a very important role in urban road construction. Their main functions include maintaining traffic order, ensuring the safety of drivers, passengers, and pedestrians, and preventing and reducing traffic accidents. Concrete guardrails are a type of road guardrail that are prefabricated by pouring concrete into a mold vehicle and then curing it. After production, prefabricated concrete guardrails are usually unloaded using a guardrail unloading device. For example, the Chinese utility model patent with authorization announcement number CN218200924U discloses a suction cup guardrail unloading device that uses vacuum suction cups to remove guardrails from a mold vehicle and arrange them in an orderly manner. However, its structure is only applicable to single-mold guardrail mold vehicles.

[0003] With the increasing demand for concrete guardrails, single-mode guardrail mold carts are no longer able to meet production requirements, and dual-mode guardrail mold carts are needed to increase daily production. Because the two guardrails in a dual-mode guardrail mold cart are placed end-to-end, and the concrete guardrails have an asymmetrical structure with one flat side and the other raised. This means that after removing the concrete guardrails from the dual-mode guardrail mold cart using the guardrail unloading device described above, they can only be placed end-to-end, not in a forward-facing arrangement, which makes subsequent transportation difficult.

[0024] During use, after the vacuum suction cup 21 takes the concrete guardrail 16 out of the double-mold guardrail mold vehicle, the suction cup bracket 20 is driven to flip through the action of the flip driving component, thereby driving the concrete guardrail 16 to flip through the vacuum suction cup 21, and realizing the erection of the concrete guardrail 16. Then, the motor 10 is driven to rotate the driving gear 8, and the outer ring of the slewing bearing 6 is driven to rotate through the gear teeth 7, thereby driving the concrete guardrail 16 to rotate through the rotating mounting plate 13, the suction cup bracket 20 and the vacuum suction cup 21, and realizing the forward placement of the concrete guardrail 16. The rotation transmission is completed by the engagement of the driving gear 8 and the gear teeth 7, which can ensure that the operation process runs smoothly and without vibration, and effectively prevents damage to the concrete guardrail 16 that has just been produced and cured.
