Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and together with the description, serve to explain the principles of the application.

FIG. 1 is a schematic overall structure of a hitch shown in accordance with an exemplary embodiment;

1. a base; 12. hanging holes; 13. a guide chute; 14. a side guide wall; 15. mounting holes; 16. a weight reduction zone.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

As shown in FIG. 1, an exemplary embodiment illustrates a hitch, comprising: the base 1, wherein the base 1 is last to have offered hitching hole 12 and direction chute 13, and direction chute 13 extends to hitching hole 12 department from the tip of base 1 for in leading external towing pin to hitching hole 12, accomplish the lock of hanging. Compared with the prior art, the embodiment of the utility model provides a guide through direction chute 13 carries out the hasp with outside towing pin guide to hitching hole 12 in, avoids using the spring buckle structure of easy old damage unhook, can bear the skip that the quality is bigger, reduces cost of transportation. In addition, the connection mode of the embodiment is simpler, and only the skip car needs to be driven to be close to the AGV car provided with the hanging device, so that the traction pin slides upwards along the bottom of the guide chute 13 and falls into the hanging hole to be locked when the traction pin slides to the hanging hole 12. Meanwhile, the guide chute 13 and the base 1 are integrally formed, so that the weight of the base 1 is reduced, the number of parts is reduced, the process steps of assembly are omitted, the overall strength of the hanging device is enhanced, and the heavy skip car can be borne while the hanging device is not easy to damage.

In some embodiments, corresponding to the structure of the guide chute 13, as shown in fig. 1, the hooking hole 12 is a counter bore opened on the guide chute 13. At the same time, for the pin to rotate flexibly and to withstand less steering pressure, the axial cross section of the hooking hole 12 is preferably designed to be pear-shaped with one wide side and one narrow side, wherein the wide side is the side exerting pressure on the skip pin.

In some embodiments, as shown in fig. 1, in order to balance the locking stability of the towing pin and the hitching hole 12 and the pulling force requirement of the towing bar on the skip car, the included angle between the guide chute 13 and the horizontal plane is set to be 30-40 °, and the towing pin is not firmly hitched and is easy to unhook when the included angle is too small. The included angle is too big, and the traction lever is big with the contained angle of horizontal plane, and the pulling force that acts on the skip horizontal direction reduces greatly, is unfavorable for the pulling work of AGV dolly, therefore the contained angle of this embodiment direction chute 13 and horizontal plane is preferred 30.

In some embodiments, as shown in fig. 1, the side walls of the guide chute 13 are arranged perpendicular to the base 1, forming side guide walls 15 to limit the swing range of the drawbar on the external traction pin. The included angle between the two side guide walls 15 is preferably 60 degrees, if the included angle is too large, when the AGV trolley pulls the skip car to turn, the situation that the AGV trolley finishes turning and the skip car does not turn can occur, then the skip car suddenly enters a turning stage, the turning amplitude is too large, the situation that the traction pin is broken due to too large instant tension is easily caused, and the risk that the skip car turns on one side is easily caused. If the angle is too small, the steering capacity of the skip car is weakened due to the limitation of the swing range of the traction rod, which is not beneficial to the smooth completion of the traction process.

In some embodiments, as shown in fig. 1, a plurality of mounting holes 15 are formed on the base 1, and the base 1 is fixed on the skip car through the mounting holes 15. As shown in fig. 1, the mounting holes 15 are divided into two groups and symmetrically arranged on both sides of the guide chute 13.

In some embodiments, as shown in fig. 1, the base 1 is further provided with a weight-reducing area 16 with a hollow structure, so as to further reduce the weight of the hitch and save the cost.

In the description herein, reference to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Although embodiments of the present application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present application, and that variations, modifications, substitutions and alterations may be made to the above embodiments by those of ordinary skill in the art within the scope of the present application.
