Description
Technical Field
[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to a comb-tooth type AGV transporter. Background Art
[0002] At present, in order to improve the handling efficiency, AGV vehicle plate transporters have begun to be used in stereo garages to make vehicle storage and retrieval flexible. When the common AGV vehicle plate transporter is working, it is necessary to first place the vehicle plate at the vehicle entrance and exit. After the vehicle enters the vehicle plate, the AGV vehicle plate transporter then places the vehicle plate carrying the vehicle to the parking position, so that the AGV vehicle plate transporter reciprocates to transport the vehicle plate, resulting in low vehicle storage and retrieval efficiency. The comb-tooth exchange stereo garage only needs to place an import and export comb rack at the vehicle entrance and exit position, and the vehicle storage and retrieval can be completed using the exchange comb rack. However, how to use the AGV transporter to achieve vehicle storage and retrieval in the comb-tooth stereo garage has always been a technical problem that has troubled technicians in this field.
[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement of the comb-tooth AGV transporter, 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. Utility Model Content

[0008] As a further improvement, the upper end of the first connecting rod and the lower end of the second connecting rod are both provided with supporting rollers.
[0009] As a further improvement, the lifting power device includes a lifting cylinder, a cylinder body of the lifting cylinder is hinged to the transport frame, and a piston rod of the lifting cylinder is hinged to the first hinge shaft.

[0011] After adopting the above technical solution, the beneficial effects of the utility model are:
[0012] The comb-tooth type AGV carrier provided by the utility model is provided with an exchange comb-tooth frame on the lifting frame, so that a vehicle can be taken out from the comb-tooth frame at the vehicle entrance and exit and placed in a parking position together with the exchange comb-tooth frame, without having to repeatedly place the comb-tooth frame at the vehicle entrance and exit, thus saving vehicle access time and improving vehicle access efficiency; since a single-stage scissor-fork mechanism is used, the lifting frame is avoided from being tilted due to the jamming of multiple parts linkage, and the lifting and lowering stability of the exchange comb-tooth frame is improved.

[0020] like Figure 1 and Figure 2 As shown, a comb-tooth type AGV carrier comprises a transport frame 1, a lifting frame 2 driven by a lifting mechanism is arranged on the transport frame 1, a comb-tooth exchange frame 3 is arranged on the lifting frame 2, the comb-tooth exchange frame 3 comprises two horizontal beams 301 arranged in parallel and at intervals, two longitudinal beams 302 arranged in parallel and at intervals are arranged between the two horizontal beams 301, the horizontal beams 301 are arranged perpendicularly to the longitudinal beams 302, a plurality of comb teeth are arranged on each longitudinal beam 302, and the comb teeth are arranged in parallel with the horizontal beams 301. The comb-tooth exchange frame 3 is the present invention. The structure of the components commonly used by technicians in this field is well known to those skilled in the art and will not be described in detail here. A positioning cone 9 is provided on the lifting frame 2, and the free end of the positioning cone 9 is vertically upward. In order to facilitate the positioning and fixing of the exchange comb rack 3, at least two positioning cones 9 are usually provided. A positioning seat 10 is provided on the longitudinal beam 302 of the exchange comb rack 3, and a positioning hole 11 matched with the positioning cone 9 is provided on the positioning seat 10. The exchange comb rack 3 can be combined with or separated from the lifting frame 2 in the vertical direction to realize the storage and retrieval of the vehicle.
[0021] The lifting mechanism includes a scissor mechanism driven by a lifting power device. The scissor mechanism is provided with two groups and is located on the left and right sides of the lifting frame 2. Specifically, the scissor mechanism includes a first connecting rod 4 and a second connecting rod 5 hinged together by a first hinge shaft 6. The first connecting rod 4 and the second connecting rod 5 are cross-arranged. The first hinge shaft 6 is located in the middle of the first connecting rod 4, and similarly, it is also located in the middle of the second connecting rod 5. The lower end of the first connecting rod 4 is hinged to the transport frame 1 through the second hinge shaft 7, and the lower end of the second connecting rod 5 is linearly slidably installed on the transport frame 1. Usually, a linear slide rail is provided on the transport frame 1, and a slider is slidably installed on the linear slide rail. The lower end of the second connecting rod 5 is hingedly installed. On the slider, a linear sliding is formed relative to the transport frame 1, and a roller-track combination structure can also be used. Technical personnel in this field can choose to use it according to their needs, and will not go into details here. The upper end of the second connecting rod 5 is hinged to the lifting frame 2 through the third hinge shaft 8, and the upper end of the first connecting rod 4 is linearly slidably installed on the lifting frame 2. Its structure can refer to the sliding structure of the lower end of the second connecting rod 5. The second hinge shaft 7 and the third hinge shaft 8 are both arranged parallel to the axis of the first hinge shaft 6. The upper end of the first connecting rod 4 and the lower end of the second connecting rod 5 are both provided with supporting rollers 12, which are used in conjunction with the tracks correspondingly fixed on the transport frame 1 or the lifting frame 2 to achieve their linear sliding.
[0022] The lifting power device includes a lifting cylinder 13, each first hinge shaft 6 can be individually connected to a lifting cylinder 13, the cylinder body of the lifting cylinder 13 is hinged on the transport frame 1, and the piston rod of the lifting cylinder 13 is hinged on the first hinge shaft 6. The extension or retraction of the piston rod of the lifting cylinder 13 drives the change of the angle between the first connecting rod 4 and the second connecting rod 5, thereby making the exchange comb rack 3 vertically lift and lower.
[0023] The scissor mechanism has high lifting synchronization and is stable in lifting. The two sets of scissor mechanisms can use the same first hinge shaft 6 and use a lifting cylinder 13 to drive the two sets of scissor mechanisms to lift, further improving the lifting stability of the exchange comb rack 3.

Figure 1 As shown, lift the exchange comb rack 3 and move it to the parking position for storage; when taking the car, the reverse operation is performed, which will not be repeated 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.
