[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to an AGV transporter. Background Art
[0002] At present, in the multi-story parking garage, in order to improve the handling efficiency, AGV carriers have begun to be used, so that the vehicle storage and retrieval is flexible and efficient. The common AGV carrier is a clamping wheel structure, and a clamping arm needs to be installed on the handling frame of the AGV carrier. In order to store the vehicle in the second-floor parking space, a lifting mechanism needs to be set on the handling frame of the AGV carrier. The lifting mechanism occupies a large amount of height space, which results in a bulky AGV carrier structure and a high handling frame height. On the one hand, it is not conducive to clamping the vehicle tires, and on the other hand, it increases the weight of the AGV carrier and increases the manufacturing cost.
[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement of AGV transporters, which is also a research hotspot and focus in the current stereo garage technology field, and is also the starting point for the completion of the present utility model.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2 As shown, an AGV carrier comprises a carrier frame 1, and a group of lifting mechanisms are respectively provided at both ends of the carrier frame 1. With the carrier's travel direction as the front, the two groups of lifting mechanisms are respectively located at the front end and the rear end of the carrier frame 1. Specifically, the lifting mechanism comprises a first connecting rod 2 and a second connecting rod 3 hinged together by a first hinge shaft 7. The first connecting rod 2 and the second connecting rod 3 are cross-arranged. The first hinge shaft 7 is located in the middle of the first connecting rod 2, and similarly, it is also located in the middle of the second connecting rod 3. The lower end of the first connecting rod 2 is hinged to the carrier frame 1 through the second hinge shaft. The second hinge shaft is arranged parallel to the axis of the first hinge shaft 7. The lower end of the second connecting rod 3 is linearly slidably installed on the carrier frame 1. Usually, a linear slide rail is arranged on the carrier frame 1, and a slider is slidably installed on the linear slide rail. The lower end of the second connecting rod 3 It is hingedly installed on the slider to form a linear sliding relative to the transport frame 1. The lower end of the first connecting rod 2 is close to the end of the transport frame 1, and the lower end of the second connecting rod 3 is far away from the end of the transport frame 1. The upper ends of the first connecting rod 2 and the second connecting rod 3 are both provided with supporting parts for supporting the vehicle loading plate 9, and the vehicle loading plate 9 is placed on the upper ends of the first connecting rod 2 and the second connecting rod 3. A lifting cylinder 8 is provided on the transport frame 1, and the cylinder body of the lifting cylinder 8 is hinged on the transport frame 1. The piston rod of the lifting cylinder 8 is hinged on the first hinge shaft 7. The extension or retraction of the piston rod of the lifting cylinder 8 drives the change of the angle between the first connecting rod 2 and the second connecting rod 3, so that the vehicle loading plate 9 is vertically lifted and lowered. The lifting cylinder 8 is a two-stage cylinder, and more stages can be set as needed to shorten the length of the cylinder body of the lifting cylinder 8 while meeting the lifting height of the vehicle loading plate 9.
[0021] A supporting roller 4 is provided at the upper end of the first connecting rod 2, and the supporting roller 4 can roll on the lower surface of the vehicle loading plate 9 to facilitate the change of the angle between the first connecting rod 2 and the second connecting rod 3. A supporting block 5 is provided at the upper end of the second connecting rod 3, and the supporting block 5 supports the lower surface of the vehicle loading plate 9 and is relatively stationary with the vehicle loading plate 9, so that the vehicle loading plate 9 can be raised and lowered without sliding sideways.
[0022] A sensor 6 for detecting the height of the loading plate is provided on the transport frame 1. The sensor 6 is usually a navigation sensor, a distance sensor, or a wire sensor. Technical personnel in this field can choose to use it according to their needs. Examples are not given here one by one. In order to place the loading plate 9 stably, two sensors 6 are provided, which are located at the front and rear ends of the transport frame 1 respectively. They detect the heights of the two ends of the loading plate 9 in real time, and adjust the oil intake of the lifting cylinder 8 in real time to avoid tilting of the loading plate 9 due to height difference.
[0023] Each lifting mechanism includes two sets of first connecting rods 2 and second connecting rods 3 arranged at intervals, and the two sets of first connecting rods 2 and second connecting rods 3 are respectively located on both sides of the transport frame 1, and the two sets of first connecting rods 2 and second connecting rods 3 share the same first hinge shaft 7. The piston rod of the lifting cylinder 8 is hinged at the middle position of the first hinge shaft 7, so that the force of the two sets of first connecting rods 2 and second connecting rods 3 is uniform, and the loading plate 9 is kept rising and falling smoothly; the two sets of first connecting rods 2 and second connecting rods 3 can also be separately controlled by one lifting cylinder 8. The technicians in this field can choose to use it according to their needs, and no further details are given.
[0024] When parking a vehicle, the loading plate 9 is placed on the support point at the entrance and exit. The vehicle drives onto the loading plate 9 at the entrance and exit. The AGV transporter moves to the position below the loading plate 9, and the piston rod of the lifting cylinder 8 extends. Figure 2 As shown, the vehicle loading plate 9 is lifted up and moved to the parking position for storage; the reverse operation is performed when the vehicle is taken out, which will not be described in detail here.
[0025] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
