Anti-misentry stacker overhead rail turnout mechanism

Abstract

This utility model discloses a mechanism to prevent stacker crane from accidentally entering the turn of the first turnout when the stacker crane is traveling along the straight track. This mechanism solves the problem that when the stacker crane is traveling along the straight track, the rear guide wheel accidentally enters the turn of the first turnout, causing the upper beam of the stacker crane to get stuck and the stacker crane to be obstructed. A horizontal cantilever (7) of the turnout side rail is provided on the straight track (1) in front of the turnout turnout (2). An anti-accidental entry guide rail (8) is suspended at the outer end of the horizontal cantilever (7). A horizontal cantilever (9) of the upper beam (4) of the stacker crane is provided at the rear end of the turnout side beam. An anti-accidental entry side guide wheel (10) is provided on the horizontal cantilever (9) of the upper beam (4). The anti-accidental entry side guide wheel (10) and the anti-accidental entry guide rail (8) are movably engaged together. This ensures that the rear guide wheel of the upper beam of the stacker crane can smoothly enter the straight track without entering the turnout. The structure is simple and ingenious.

Description

Technical Field

[0001] This utility model relates to a stacker crane, and more particularly to a mechanism that can prevent the stacker crane from accidentally entering the overhead rail switch of the stacker crane during operation. Background Technology

[0002] Stacker cranes are widely used in automated warehousing and logistics systems. These cranes operate between ground rails and overhead rails. The overhead rail guide wheel system on the upper crossbeam of the stacker crane works in conjunction with the overhead rails to guide the crane. A drive system is installed on the lower crossbeam of the stacker crane to drive its movement. In automated warehouses, straight tracks are installed, connected to turning branch tracks. Some straight tracks have two turning branch tracks, and the distance between two adjacent branch tracks is equal to the length of the upper crossbeam of the stacker crane. When the stacker crane travels along the straight tracks, after the front guide wheel on the upper crossbeam passes the first turning branch, if it continues to the second turning branch, the rear guide wheel on the upper crossbeam will enter the unrestricted area of ​​the first turning branch. This makes it easy for the rear guide wheel to mistakenly enter the turning lane of the first turning branch, causing the upper crossbeam of the stacker crane to jam and hindering the crane's movement. Overcoming this problem is a key issue that needs to be addressed on-site. Summary of the Invention

[0003] This utility model provides a mechanism to prevent accidental entry into the overhead rail switch of a stacker crane, solving the technical problem of how to overcome the accidental entry of the guide wheel at the rear end of the upper beam into the switch.

[0004] This utility model solves the above technical problems through the following technical solution:

[0005] An anti-misguided entry mechanism for a stacker crane overhead rail switch includes a straight overhead rail and an upper crossbeam of the stacker crane. A front guide wheel is located at the front end of the upper crossbeam, and a rear guide wheel is located at the rear end. A front turning switch and a rear turning switch are connected to the straight overhead rail, with the distance between them equal to the length of the upper crossbeam. A horizontal cantilever arm for the switch side is located on the straight overhead rail in front of the rear turning switch, and an anti-misguided entry guide rail is suspended at the outer end of the horizontal cantilever arm. A horizontal cantilever arm for the switch side upper crossbeam is located at the rear end of the upper crossbeam, and an anti-misguided entry side guide wheel is located on the horizontal cantilever arm, with the anti-misguided entry side guide wheel movably engaged with the anti-misguided entry guide rail.

[0006] A straight track disconnection area is set between the rear turning turn and the straight track. The anti-misconduct guide rail is set below the front side of the straight track disconnection area, and the anti-misconduct side guide wheel is set in front of the rear guide wheel of the upper crossbeam.

[0007] The horizontal plane where the anti-accidental entry side guide wheel is located is parallel to the horizontal plane where the rear guide wheel of the upper crossbeam is located, and the central axis of the anti-accidental entry side guide wheel is parallel to the central axis of the rear guide wheel of the upper crossbeam.

[0008] This invention ensures that the guide wheel at the rear end of the upper crossbeam smoothly enters the straight track when the stacker crane continues to move forward after passing the turn-off lane, without entering the turn-off lane. The structure is simple and ingenious. Attached Figure Description

[0011] The present invention will now be described in detail with reference to the accompanying drawings:

[0012] An anti-misguided entry mechanism for a stacker crane overhead rail switch includes a straight overhead rail 1 and a stacker crane upper beam 4. A front guide wheel 5 is provided at the front end of the stacker crane upper beam 4, and a rear guide wheel 6 is provided at the rear end of the stacker crane upper beam 4. A front turning switch 3 and a rear turning switch 2 are respectively connected to the straight overhead rail 1, and the distance between the front turning switch 3 and the rear turning switch 2 is equal to the length of the stacker crane upper beam 4. A switch-side overhead rail horizontal cantilever 7 is provided on the straight overhead rail 1 in front of the rear turning switch 2, and an anti-misguided entry guide rail 8 is suspended at the outer end of the switch-side overhead rail horizontal cantilever 7. A switch-side upper beam horizontal cantilever 9 is provided at the rear end of the stacker crane upper beam 4, and an anti-misguided entry side guide wheel 10 is provided on the switch-side upper beam horizontal cantilever 9. The anti-misguided entry side guide wheel 10 is movably engaged with the anti-misguided entry guide rail 8.

[0013] A straight track disconnection area 11 is provided between the rear turning turn 2 and the straight track 1. An anti-misconduct guide rail 8 is provided below the front side of the straight track disconnection area 11, and an anti-misconduct side guide wheel 10 is provided in front of the rear guide wheel 6 of the upper crossbeam.

[0014] The horizontal plane where the anti-accidental entry side guide wheel 10 is located is parallel to the horizontal plane where the upper crossbeam rear guide wheel 6 is located, and the central axis of the anti-accidental entry side guide wheel 10 is parallel to the central axis of the upper crossbeam rear guide wheel 6.

[0015] When the front end of the stacker crane travels along the straight track 1 and passes the rear turnout 2, before the rear guide wheel 6 of the upper crossbeam enters the straight track disconnection area 11, the anti-mis-entry side guide wheel 10, which is installed on the horizontal cantilever 9 of the upper crossbeam on the turnout side of the stacker crane, first enters the anti-mis-entry guide rail 8 area, so that the anti-mis-entry side guide wheel 10 and the anti-mis-entry guide rail 8 are engaged together. The engagement between the anti-mis-entry side guide wheel 10 and the anti-mis-entry guide rail 8 is released only after the rear guide wheel 6 of the upper crossbeam passes the straight track disconnection area 11, thus ensuring that the rear guide wheel 6 of the upper crossbeam will not mistakenly enter the rear turnout 2.

[0016] If the front end of the stacker crane turns along the straight track 1 into the rear turning turnout 2, the anti-mis-entry guide wheel 10 will turn together with the upper crossbeam 4 of the stacker crane, so that the horizontal cantilever 9 of the upper crossbeam on the turnout side and the anti-mis-entry guide wheel 10 avoid the anti-mis-entry guide rail 8 in advance, so that the anti-mis-entry guide wheel 10 and the anti-mis-entry guide rail 8 will not interfere with each other, thus ensuring the smooth turning of the stacker crane.
