Description

Technical Field

[0001] This utility model relates to the field of intelligent parking equipment, specifically an adjustable guide wheel device for parking AGVs. Background Technology

[0002] The technology of intelligent automatic parking equipment is gradually developing. The most common method is to use AGVs to transport cars. Most existing parking AGVs use a fixed guide wheel structure. During on-site debugging, due to manufacturing and installation errors, the center distance of the track on site deviates from the theoretical design value. Since the guide wheels cannot be adjusted, there is a gap between the guide wheels and the track. This causes the parking AGV to sway left and right when it moves. In severe cases, it can cause the vehicle body to get stuck. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art and to provide an adjustable guide wheel device for parking AGV.

[0004] This utility model provides the following technical solution: an adjustable guide wheel device for a parking AGV, including a traveling frame, with at least two sets of guide wheel mechanisms on each side of the traveling frame. Each set of guide wheel mechanisms includes a connecting plate, a guide wheel bracket, and a guide wheel. The guide wheel is rotatably connected to the guide wheel bracket. The connecting plate is fixedly connected to the traveling frame. The connecting plate has an oblong hole, the long axis of which is arranged perpendicular to the width direction of the traveling frame. The guide wheel bracket is connected to the connecting plate by a bolt A and a nut, with the bolt A passing through the oblong hole. A limiting mechanism is provided at one end of the connecting plate near the center of the traveling frame. The limiting mechanism is used to limit the position of the bolt A, so that the outer side of the guide wheel is in close contact with the track.

[0005] Preferably, there are two oblong holes arranged in parallel, and each oblong hole is fitted with a bolt A.

[0006] Preferably, the limiting mechanism includes two vertically arranged ear plates, each ear plate having a threaded hole, a bolt B installed in the threaded hole, and a nut installed on each side of the ear plate, the nuts being threadedly connected to the bolt B, with one end of the bolt B extending toward the corresponding bolt A.

[0007] Preferably, the guide wheel bracket is equipped with a pin, and the pin is equipped with two rolling bearings. The guide wheel is rotatably connected to the pin through the rolling bearings.

[0008] Preferably, the connecting plate is welded and fixed to the traveling frame.

[0009] Preferably, a set of guide wheel mechanisms is provided at each of the four corners of the traveling frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: when there is a deviation between the center distance of the track on site and the theoretical design value, the adjustable guide wheel device can make the guide wheel always move close to the side of the track according to the actual size on site, with no gap between the guide wheel and the track, so that the parking AGV will not sway left and right when it moves, thus avoiding the problem of the parking AGV getting stuck.

[0017] Please see Figure 1-5 This embodiment is an adjustable guide wheel device for a parking AGV, including a traveling frame 1. At least two sets of guide wheel 4 mechanisms are provided on each side of the traveling frame 1. Each set of guide wheel 4 mechanisms includes a connecting plate 2, a guide wheel bracket 3, and a guide wheel 4. The guide wheel 4 is rotatably connected to the guide wheel bracket 3. The connecting plate 2 is fixedly connected to the traveling frame 1. The connecting plate 2 is provided with an oblong hole 10. The long axis of the oblong hole 10 is arranged perpendicular to the width direction of the traveling frame 1. The guide wheel bracket 3 is connected to the connecting plate 2 by a bolt A8 and a nut. The bolt A8 passes through the oblong hole 10. A limiting mechanism is provided at one end of the connecting plate near the center of the traveling frame 1. The limiting mechanism is used to limit the position of the bolt A8 so that the outer side of the guide wheel 4 is in close contact with the track 7.

[0018] Preferably, there are two oblong holes 10, which are arranged in parallel, and each oblong hole 10 is fitted with a bolt A8.

[0019] Preferably, the limiting mechanism includes two vertically arranged ear plates 6, each ear plate 6 is provided with a threaded hole, a bolt B9 is installed in the threaded hole, a nut is installed on each side of the ear plate 6, the nut is threadedly connected to the bolt B9, and one end of the bolt B9 extends toward the corresponding bolt A8.

[0020] Preferably, the guide wheel bracket 3 is equipped with a pin 5, and the pin 5 is equipped with two rolling bearings. The guide wheel 4 is rotatably connected to the pin 5 through the rolling bearings.

[0021] Preferably, the connecting plate 2 is welded and fixed to the traveling frame 1.

[0022] Preferably, a set of guide wheels 4 is provided at each of the four corners of the traveling frame 1.

[0023] The working principle of this utility model is as follows: The four corners of the parking AGV walking frame are designed with four sets of adjustable guide wheels 4. When there is a deviation between the center distance of the track 7 on site and the theoretical design value, the bolts A8 and B9 are loosened according to the actual deviation, and the position of the guide wheel bracket 3 is adjusted so that the guide wheel 4 is completely in contact with the track 7. Then the nut of the bolt A8 is tightened. Finally, the limit length of the bolt B9 is adjusted according to the position of the bolt A8 so that the bolt B9 presses against the bolt A8, so as to prevent the bolt A8 from loosening and shifting during operation, thereby preventing the guide wheel 4 from falling off the track 7 again during later operation.
