Description

Technical Field

[0001] The utility model relates to the field of logistics automatic transportation, in particular to an RGV large-platform auxiliary dynamic support device. Background Art

[0002] Due to the popularization of Industry 4.0, the popularization range of automatic transportation equipment is getting wider and wider. Taking the logistics industry and the automobile manufacturing and assembly industry as the vanguard, other traditional manufacturing and assembly industries have also successively used automatic transportation equipment. The existing RGV transport trolley adopts an integral frame, which makes the products tend to swing outwards at the track turning point. The loaded products need to achieve antagonism through the friction force between the load-bearing platform, which leads to the unstable operation of the existing RGV.

[0003] Therefore, due to the instability of the traditional RGV transport trolley when turning, the height and weight of the carried products are restricted. Therefore, it is necessary to improve such a structure to overcome the above defects. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an RGV large-platform auxiliary dynamic support device. The utility model is realized through the following technical solutions:

[0005] An RGV large-platform auxiliary dynamic support device includes a main body frame and two power components. The power components include an auxiliary frame, a driving trolley group, and a sliding trolley group. The auxiliary frame is rotationally connected to the main body frame. The auxiliary frame is fixedly connected to the driving trolley group and the sliding trolley group. The driving trolley group includes a motor and a driving wheel. The sliding trolley group includes a follower wheel.

[0006] In the above technical solution: The main body frame is used to place goods and set the remaining components; the power components are used to provide power to make the main body frame move on the track; the auxiliary frame is used to set the driving trolley group and the sliding trolley group and keep the relative distance between them unchanged; the motor is used to provide power for the driving wheel; the driving wheel is used to move on the track; the follower wheel is used to move on the track as the driving wheel moves, so as to keep the horizontal attitude of the auxiliary frame.

[0007] The further setting of the utility model is: It also includes two plain bearings. The outer ring of the plain bearing is connected to the bottom surface of the main body frame, and the inner ring of the plain bearing is connected to the upper surface of the auxiliary frame.

[0008] In the above technical solution: The plain bearing is used to realize the relative rotation between the auxiliary frame and the main body frame, so that the attitude change of the main body frame is small and stable when turning.

[0009] A further setting of the utility model is that the active trolley group further includes an active frame, the motor is fixedly arranged on the active frame, and the driving wheel is connected to the output end of the motor.

[0010] In the above technical solution: the active frame is used to set the driving wheel so that the driving wheel is vertical, so as to stably contact the track.

[0011] A further setting of the utility model is that a plurality of first guide wheels are rotatably arranged on the active trolley group.

[0012] In the above technical solution: the first guide wheel is used to prevent the active frame from moving left and right randomly, so that the driving wheel can always contact the track.

[0013] A further setting of the utility model is that the sliding trolley group further includes a follower frame, the follower wheel is rotatably arranged on the follower frame, and a plurality of second guide wheels are rotatably arranged on the sliding trolley group.

[0014] In the above technical solution: the follower frame is used to set the follower wheel to ensure that the follower wheel can maintain a vertical posture; the second guide wheel is used to prevent the follower frame from moving left and right randomly, so that the follower wheel can always contact the track.

[0015] A further setting of the utility model is that a limiting plate is further arranged on the bottom surface of the main frame.

[0016] In the above technical solution: the limiting plate is used to limit the rotation angle of the auxiliary frame relative to the main frame and prevent the main frame from tipping over.

[0017] The utility model discloses an RGV large platform auxiliary dynamic support device. Compared with the prior art:

[0018] 1. Through the setting of the main frame and the plane bearing of the auxiliary frame in the utility model, when turning, the main frame will not have a rapid angle change, thereby avoiding excessive centrifugal tendency of the goods thereon, further avoiding the position change of the goods, and even slipping off;

[0019] 2. The utility model also sets a limiting plate, so that the relative angle between the auxiliary frame and the main frame will not be too large, thereby avoiding the tipping over of the main frame caused by the too large angle between the two, and making the transportation more stable.
