Technical Field
[0001] The utility model belongs to the field of mechanical devices and transportation, and particularly relates to an auxiliary device for an AGV trolley to pass through obstacles of a flat car track wheel rim groove. Background Art
[0002] In some automated production line applications, both AGVs and flat carts operate in the same work environment. The flat carts are equipped with a track that is designed to work with them. The track is located within the flat cart track groove, with one side of the track forming the flat cart track wheel rim groove. In actual use, the AGV may pass through the flat cart track wheel rim groove. However, the width of the flat cart track wheel rim groove is relatively wide relative to the diameter of the AGV's wheels. Due to the influence of the track wheel rim groove, the AGV with smaller wheels may become stuck when traveling into the flat cart track wheel rim groove, resulting in unstable operation of the AGV and reducing the AGV's operating range.
[0003] How to ensure that the AGV trolley can cross the flat car track wheel rim groove obstacle without affecting the flat car operation is an urgent problem to be solved. In order to solve the above problem, an auxiliary device for the AGV trolley to cross the flat car track wheel rim groove obstacle is designed. Summary of the Invention
[0004] The purpose of the utility model is to address the deficiencies of the existing technology and provide an auxiliary device for an AGV trolley to pass through a flat car track wheel rim groove obstacle, which has a simple structure, automatic reset and stable operation.
[0005] The technical objectives of the present invention are achieved through the following technical solutions:
[0006] The cam is secured to the chassis and has two guide rails that are adapted to move along the chassis, and the cam is secured to the chassis by means of a spring that is adapted to move the cam forward and backward relative to the chassis.
[0007] The elastic support device consists of a base plate, a guide column and a return spring; the length of the guide column is smaller than the length of the return spring; the base plate is fixed in the wheel rim groove of the flat car track, the guide column is fixed on the base plate, the upper end of the return spring is fixedly connected to the lower end of the guide support plate, it is sleeved on the guide column and the lower end is fixedly connected to the upper end surface of the base plate.
[0008] The return spring is a compression spring.
[0009] The included angle between the inclined guide plate and the main body of the guide support plate is 165°~170°.
[0010] The height of the inclined guide plate is smaller than the height of the elastic supporting device.
[0011] The height of the guide column is less than or equal to the height of the compressed return spring.
[0012] The upper end of the guide column is provided with an introduction chamfer.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. This utility model provides a guide support plate within the flat car track wheel rim groove, and securely mounts multiple elastic support devices beneath the guide support plate. The upper end surface of the guide support plate is flush with the upper end surface of the flat car track wheel rim groove, thereby supporting the AGV wheels when the trolley passes through obstacles in the track wheel rim groove.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.
[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.
[0029] like Figure 1 — Figure 5The guide plate 3 is provided with a plurality of elastic support devices 4 at two ends thereof, and the guide plate 3 is provided with an elastic support device 4 fixed under the guide support plate 3. The guide support plate 3 is provided along the length direction of the flat car track wheel rim groove 1, and downwardly inclined inclined guide plates 31 are symmetrically provided at both ends thereof. The width of the guide support plate 3 is slightly smaller than the width of the flat car track wheel rim groove 1. The guide support plate 3 is provided with a plurality of elastic support devices 4 at intervals along its length direction. The upper end of the elastic support device 4 is fixedly connected to the lower end of the guide support plate 3, and the lower end is fixedly installed in the flat car track wheel rim groove 1. The upper end surface of the guide support plate 3 is flush with the upper end surface of the flat car track wheel rim groove 1. When the wheel rim 51 of the flat car walks on the guide support plate 3, under the influence of the flat car's own weight, the guide support plate 3 drops to the bottom end of the wheel rim 51 of the flat car, and does not exceed the maximum compression amount of the elastic support device 4. By setting a guide support plate 3 in the flat car track wheel rim groove 1 and fixing a plurality of elastic support devices 4 under the guide support plate 3, wherein the upper end surface of the guide support plate 3 is flush with the upper end surface of the flat car track wheel rim groove 1, the AGV trolley 6 can support the trolley wheel 61 when passing through the track wheel rim groove obstacle, thereby avoiding the AGV trolley 6 from getting stuck when traveling to the track wheel rim groove when the trolley wheel 61 is small, and at the same time, does not affect the smooth operation of the wheel rim 51 of the flat car in the flat car track wheel rim groove 1. The adoption of this technical measure has the advantages of simple structure, automatic reset and smooth operation.
[0030] like Figure 1 As shown, the main body of the guide support plate 3 is a long plate-like structure, with downward-inclined inclined guide plates 31 symmetrically provided at both ends. The guide support plate 3 is arranged along the length direction of the flat car track wheel rim groove 1; the width of the guide support plate 3 is slightly smaller than the width of the flat car track wheel rim groove 1, and there is a clearance fit between the guide support plate 3 and the flat car track wheel rim groove 1. Specifically, one side of the guide support plate 3 is close to the track 2, and the other side is close to the inner side of the flat car track wheel rim groove 1. In actual use, the main body of the guide support plate 3 is made of Q235 quenched and tempered material, and inclined guide plates 31 made of Q235 quenched and tempered material are welded at both ends.
[0031] like Figure 1 、 Figure 5As shown, the angle between the inclined guide plate 31 and the main body of the guide support plate 3 is 165°~170°. By providing the inclined guide plate 31, it can play a good guiding role when the flat car enters the flat car track wheel rim groove 1, and at the same time, it plays a supporting role for the wheel rim 51 of the flat car. In actual use, the angle between the inclined guide plate 31 and the main body of the guide support plate 3 should not be too small or too large. If the angle is too small, the flat car will require greater power when moving to the guide support plate 3 through the inclined guide plate 31. When the angle is too large, the inclined guide plate 31 cannot guide the flat car wheel 5, and thus cannot play a guiding role.
[0032] The height of the inclined guide plate 31 is less than the height of the elastic support device 4. That is, the height from the highest point to the lowest point of the inclined guide plate 31 is less than the overall height of the elastic support device 4. In actual use, the height from the highest point to the lowest point of the inclined guide plate 31 is less than one-quarter of the elastic support device 4.
[0033] like Figure 3 As shown, the upper end surface of the guide support plate 3 is flush with the upper end surface of the flat car track wheel rim groove 1. When the trolley wheel 61 of the AGV trolley 6 travels on the guide support plate 3, the guide support plate 3 blocks the flat car track wheel rim groove 1. The elastic support device 4 and the guide support plate 3 support the trolley wheel 61 of the AGV trolley 6, thereby allowing the AGV trolley 6 to pass through the flat car track wheel rim groove 1 smoothly without getting stuck. In actual use, the upper end surface of the flat car track wheel rim groove 1 is also flush with the upper end surface of the track 2.
[0034] At the same time, when the wheel rim 51 of the flat car walks on the guide support plate 3, the guide support plate 3 will move downward due to the flat car's own weight. When the wheel rim 51 of the flat car is away from the guide support plate 3, the guide support plate 3 will automatically reset under the elastic action of the elastic support device 4, so that the upper end surface of the guide support plate 3 is flush with the upper end surface of the track 2, thereby ensuring that the guide support plate 3 supports the trolley wheel 61 of the GV trolley 6 when the AGV trolley passes through the flat car track wheel rim groove 1.
[0035] like Figure 1 As shown, the elastic support device 4 is composed of a base plate 41, a guide column 42 and a return spring 43; the height of the guide column 42 is less than the height of the return spring 43. In actual use, the base plate 41 and the guide column 42 are both made of Q235 material.
[0036] like Figure 2As shown, the base plate 41 is circular / square, etc., and is fixed in the flat car track wheel rim groove 1. The guide post 42 is fixed to the base plate 41, and the guide post 42 is generally fixed at the center of the base plate 41. The inner diameter of the return spring 43 is larger than the outer diameter of the guide post 42. The upper end of the return spring 43 is fixedly connected to the lower end of the guide support plate 3. The return spring 43 is sleeved on the guide post 42, and the lower end is fixedly connected to the upper end surface of the base plate 41. In actual use, the base plate 41 is pre-buried in the flat car track wheel rim groove 1.
[0037] like Figure 1 — Figure 4 As shown, the return spring 43 is a compression spring. Its upper end is welded to the lower surface of the guide support plate 3, while its lower end passes through the guide post 42 and is welded to the base plate 41. This spring 43 supports the AGV trolley 6 and the wheel rim 51 of the flatcar when it passes. When the flatcar passes, the guide support plate 3 retracts to the bottom of the wheel rim 51 under the weight of the flatcar, without exceeding the spring's maximum compression.
[0038] like Figure 1 — Figure 4 As shown, the overall height of the guide support plate 3 and the elastic support device 4 is the same as that of the track 2, and the upper end surface of the guide support plate 3 is flush with the upper end surface of the track 2. The height of the track 2 is the same as the depth of the flatcar track rim groove 1. Specifically, the height of the track 2 is H1, the depth of the flatcar track rim groove 1 is H2, and the overall height of the guide support plate 3 and the elastic support device 4 when uncompressed is H3. H3 is composed of the thickness of the guide support plate 3, the height of the uncompressed return spring 43, and the thickness of the base plate 41. H3 = H1 = H2.
[0039] When the auxiliary device is in use, after the wheel rim 51 presses against the guide support plate 3, the combined height of the guide support plate 3 and the compressed elastic support device 4 is H4, which is composed of the thickness of the guide support plate 3, the height of the compressed return spring 43, and the thickness of the base plate 41. The diameter of the wheel rim 51 is R1, and the diameter of the flat cart wheel 5 is R2; H4 = H1 - (R1 - R2). The height of the guide post 42 is less than or equal to the height of the compressed return spring 43.
[0040] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
