Description

Technical Field

[0001] The utility model relates to transplanting equipment, in particular to a double-layer telescopic docking mechanism for a stacker track. Background Art

[0002] Currently, existing track expansion joint technologies primarily rely on stepped and beveled joints, which only ensure continuity on the top surface. The use of plywood and bolts on the track sides also occupies space for the stacker's anti-tilt mechanism. For stacker cranes that utilize both the top and side surfaces for guidance, these track joints cannot simultaneously meet the requirements of running the stacker's running wheels on the top surface and the lower guide wheels on the side surfaces. Furthermore, the joints can introduce drawbacks such as unstable operation and excessive noise.

[0003] For stacking cranes, the lower guide wheels of the stacking crane need to be guided by the side of the rails. Therefore, the connection of multiple sections of rails must not only ensure the safety and stability of the running wheels, but also ensure the safety and stability of the lower guide wheels of the stacking crane. Summary of the Invention

[0013] The docking groove at the rail bottom of the docking female end is composed of a third docking groove matching the second guide portion and a fourth docking groove arranged at the bottom of the third docking groove matching the second docking portion.

[0014] Preferably, the first docking portion is a rectangular and trapezoidal structure extending from both sides of the front end of the first guide portion and then tilting inwardly.

After the docking male end and the docking female end are docked, the top surface joint also has an extended intersection, and the stacker's walking wheels run more smoothly without generating vibration and noise.

[0022] The guide surfaces provided on the butt joint male end and the butt joint female end also facilitate assembly and simplify the assembly process.

[0023] In particular, the two side surfaces of the male end rail head are concavely provided with step surfaces, which fit with the fixed block convexly provided at the front end of the female end, so that the rail head of the male end fits the rail head of the female end, so that the side of the track remains continuous, ensuring that the lower guide wheel of the stacker runs smoothly on the side of the track.
