Description

Technical Field

[0001] This utility model relates to a logistics vehicle, and more particularly to a cage car tipping device. Background Technology

[0002] Existing automated delivery vehicles use traditional cargo boxes, requiring manual loading and unloading of goods upon arrival at the destination. This method is inefficient and impacts logistics efficiency. To improve efficiency, cage-carrying vehicles have emerged. These vehicles are equipped with cargo cages, where goods are placed. The automated delivery vehicle can directly load and unload the cages. To improve transport stability, lower the center of gravity of the automated delivery vehicle, and facilitate loading and unloading, the cargo cages are horizontal while on the vehicle and are flipped to an vertical position during loading and unloading, located at the rear of the vehicle. The cargo cage is flipped by a tilting frame. Therefore, the tilting frame needs to flip 90° and also move up and down in the vertical direction. For example, a fully automatic loading and unloading device for unmanned logistics vehicle cargo boxes disclosed in Chinese patent CN221141145U achieves flipping and translation through a support rod and a lifting frame guide mechanism. However, when the structure is flipped to the end of the vertical state, the lifting frame is subjected to a large force and the vertical support force is very small. This causes the lifting frame to suddenly fall to the ground in the last stroke, resulting in poor stability of the lifting frame and an unsmooth flipping. Utility Model Content

[0003] To address the aforementioned issues of poor stability and unevenness in the tilting process, this utility model provides a cage car tilting device, the specific technical solution of which is as follows: A car-mounted tilting device includes: a tilting shaft rotatably mounted at the rear of the car frame; first connectors at both ends of the tilting shaft; a tilting linkage on the tilting shaft and located between the two first connectors; a second connector at the end of the tilting linkage; third connectors on both sides of the tilting frame and opposite to the first connectors; and a fourth connector on the tilting frame and opposite to the second connectors, the fourth connector also being located between the two third connectors; wherein the tilting frame drives the third and fourth connectors to be inserted into the first and second connectors respectively, and then tilts around the tilting shaft.

[0004] Preferably, the first connector, the second connector, the third connector, and the fourth connector have the same structure, all being L-shaped.

[0005] Preferably, it further includes: an anti-detachment device, which is disposed at one end of the flipping connecting rod and is disposed opposite to the second connector, for locking the second connector and the fourth connector when the fourth connector is inserted into the second connector.

[0006] Furthermore, the anti-detachment device includes: an anti-detachment shaft disposed on the flipping connecting rod; an anti-detachment hook rotatably disposed on the anti-detachment shaft; and a counterweight disposed at one end of the anti-detachment hook, so that the anti-detachment hook is engaged with the fourth connector.

[0007] Furthermore, the end of the anti-disengagement hook is provided with an inlet ramp.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The cage car tipping device provided by this utility model does not affect the movement of the tipping frame when the tipping frame is translated. When the tipping frame is tipped, it is connected to each other through plug-in parts, so that the tipping frame can be tipped from a horizontal state to a vertical state around the tipping axis located at the rear of the frame. During the tipping process, the vertical support force is stable and reliable, and there is no sudden free fall, so the tipping is stable and smooth. Attached Figure Description

Detailed Implementation

[0010] The present invention will now be further described with reference to the accompanying drawings.

[0011] like Figures 1 to 6As shown, a cage car tipping device includes a tipping shaft 1, a first connector 31, a second connector 32, a tipping connecting rod 35, a third connector 33, and a fourth connector 34. The two ends of the tipping shaft 1 are rotatably mounted at the rear of the frame 81. The first connectors 31 are symmetrically mounted at both ends of the tipping shaft 1. One end of the tipping connecting rod 35 is fixed at the center of the tipping shaft 1, and the other end of the tipping connecting rod 35 is connected to the second connector 32. The two first connectors 31 and one second connector 32 form an isosceles triangle. The third connector 33 and the fourth connector 34 are both fixed on the tipping frame 2 and are respectively arranged opposite to the first connectors 31 and the second connector 32. The third connector 33 is located below the fourth connector 34 and is symmetrically arranged. The two third connectors 33 and one fourth connector 34 form an equilateral triangle. The flipping frame 2 drives the third connector 33 and the fourth connector 34 to be inserted into the first connector 31 and the second connector 32 respectively, and then flips around the flipping axis 1.

[0012] The tilting frame 2 first moves towards the rear of the vehicle frame 81 until the third connector 33 and the fourth connector 34 are inserted into the first connector 31 and the second connector 32 respectively. At this time, the rear of the tilting frame 2 is located outside the vehicle frame 81. Then the tilting frame 2 begins to tilt, from a horizontal state to a vertical state. The wheels at the bottom of the tilting frame 2 touch the ground. The entire tilting process is stable and smooth, without any sudden drop, which improves the reliability and stability of the tilting.

[0013] The tilting frame 2 is driven by the drive cylinder 5.

[0014] The two ends of the flip shaft 1 are fixed to the frame 81 by the connecting plate 11.

[0015] To facilitate processing and mutual insertion and separation, the first connector 31, the second connector 32, the third connector 33 and the fourth connector 34 have the same structure, all being L-shaped.

[0016] The cage car tipping device also includes an anti-detachment device 36, which is located at one end of the tipping linkage 35 and is positioned opposite to the second connector 32. This device locks the second connector 32 and the fourth connector 34 together when the fourth connector 34 is inserted into the second connector 32. Specifically, the anti-detachment device 36 includes an anti-detachment shaft 361, an anti-detachment hook 362, and a counterweight 363. The anti-detachment shaft 361 is installed at the end of the tipping linkage 35; the anti-detachment hook 362 is rotatably mounted at both ends of the anti-detachment shaft 361; and the counterweight 363 is installed at one end of the anti-detachment hook 362. That is, the hook portions of the counterweight 363 and the anti-detachment hook 362 are located on opposite sides of the anti-detachment shaft 361, and the counterweight 363 causes the anti-detachment hook 362 to engage with the fourth connector 34. To facilitate the passage of the fourth connector 34 through the anti-disengagement hook 362, the end of the anti-disengagement hook 362 opposite to the fourth connector 34 is provided with an inlet ramp. The fourth connector 34 pushes the anti-disengagement head downward through the inlet ramp so that the fourth connector 34 enters the hook part of the anti-disengagement hook 362.

[0017] After the tilting frame 2 is tilted onto the frame 81, the drive cylinder 5 continues to drive the tilting frame 2 to move towards the head of the frame 81. Under the action of the electric cylinder, the fourth connector 34 pushes open the anti-disengagement hook 362, and the fourth connector 34 separates from the second connector 32, while the first connector 31 separates from the third connector 33.

[0018] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
