Description

Technical Field

[0001] The invention relates to the technical field of AGV trolleys, and in particular to an AGV trolley connection structure which is convenient for alignment. Background Art

[0002] AGV refers to a transport vehicle equipped with an electromagnetic or optical automatic guidance device that can travel along a specified guidance path and has safety protection and various transfer functions. It is a transport vehicle that does not require a driver in industrial applications and uses a rechargeable battery as its power source. Its route and behavior can generally be controlled by a computer, or its route can be established using an electromagnetic track that is attached to the floor. The unmanned transport vehicle relies on the information provided by the electromagnetic track to move and act.

[0003] Currently, when multiple AGVs are used to transport goods at the same time, they need to be connected. However, when two carts are connected, position deviations are likely to occur between the two carts, resulting in the need to adjust the positions of the two carts multiple times. The carts need to be aligned and installed and connected, which is too cumbersome to operate. In addition, when the AGV accelerates or decelerates, the inertia generated by the connected vehicle behind will impact the cart in front, causing the connection of the carts to be impacted for a long time, which can easily cause damage to the connection. Summary of the invention

[0013] Beneficial Effects

[0014] The present invention provides an AGV trolley connection structure that is easy to align. Compared with the existing technology, it has the following beneficial effects:

[0015] (1) The present invention moves the first traction plate on the traction mechanism to the left and inserts it into the trapezoidal frame, and guides the end surface of the first traction plate to slide through the plurality of rotating columns in front and behind the trapezoidal frame. The plurality of rotating columns guide the first traction plate to move toward the limit frame, and the first traction plate drives the second traction plate to move synchronously, so that the second traction plate squeezes the first spring on the sliding rod, and the second traction plate moves forward and backward on the sliding rod for adjustment until the first traction plate and the second traction plate are gradually aligned with the limit frame. The first traction plate is gradually guided and inserted into the limit frame, and the limit plate is driven to be inserted into the limit groove by the action force of the second spring, so that the two trolleys can be easily aligned, the deviation distance can be compressed and adjusted, and the two trolleys can be quickly connected without the need to adjust the position of the trolleys multiple times. The operation is more convenient, and the efficiency of the trolley connection is improved.

[0016] (2) The present invention uses two spring dampers on the first traction plate and the second traction plate. The impact between the first traction plate and the second traction plate will drive the rotating plates on the two spring dampers to rotate and tilt. The impact force between the two trolley bodies is buffered by the action force of the two spring dampers, which can effectively reduce the impact force of the inertia of the rear trolley, effectively prevent the connection from being damaged by the impact, and ensure the service life of the connection.

[0017] (3) The present invention uses two rectangular plates on the first traction plate and the second traction plate, and the two rectangular plates are connected by a fixed plate, so that the first traction plate and the second traction plate are connected by the rectangular plate and the fixed plate, so that the connection between the first traction plate and the second traction plate is more firm, thereby ensuring the stability of the connection of multiple trolleys.
