Description

Technical Field

[0001] This invention relates to a stacker crane for automated warehouses, and more particularly to a damping stabilization method for a stacker crane. Background Technology

[0002] The key equipment in automated warehousing systems is the stacker crane. Typically, the upper part of a stacker crane is supported by guide wheels, while the horizontal drive unit is supported on ground tracks via bottom wheel boxes. Stopping is achieved by the horizontal drive motor's brake. However, with the continuous increase in stacker crane operating speed and height, during the deceleration and stopping process, a phenomenon occurs where the bottom of the stacker crane slows down due to braking, but the upper part still experiences forward inertial impact, causing the stacker crane to sway back and forth. This threatens the stability and safe operation of the stacker crane and its guide rails. Summary of the Invention

[0003] This invention provides a damping stabilization method for stacker cranes, which solves the technical problem of swaying caused by braking in existing automated warehouses.

[0004] The present invention solves the above problems through the following solution: A stacker crane with a stabilizing damping device includes a lower rail installed on the ground and an upper rail installed on the ceiling. The stacker crane is movably positioned between the lower and upper rails. A horizontal drive motor and a drive motor controller are installed on the stacker crane. An L-shaped upper crossbeam is installed on the vertical beam of the stacker crane. A damping mounting bracket with left and right horizontal directions is installed on the L-shaped upper crossbeam. The damping mounting bracket is located directly below the upper rail. The left end of the damping mounting bracket is connected to the first end of a left brake arm installed along the upper rail, and the right end of the damping mounting bracket is connected to the first end of a right brake arm installed along the upper rail. A pull rod is connected between the ends of the left and right brake arms. A damping brake wheel is installed in the middle of the left brake arm, and a guide wheel is installed in the middle of the right brake arm. The damping brake wheel and the guide wheel are respectively clamped on the left and right sides of the upper rail. An electromagnetic brake is installed on the axle of the damping brake wheel, and the electromagnetic brake is electrically connected to the drive motor controller.

[0005] The left end of the damping mounting bracket is hinged to the first end of the left brake arm by a pin, and the right end of the damping mounting bracket is hinged to the first end of the right brake arm by another pin; a tension spring and a tension nut are provided on the pull rod.

[0006] This invention features a simple and compact structure, stable operation, and high safety and reliability, eliminating potential safety hazards in the operation of stacker cranes. Attached Figure Description

[0008] A stacker crane with a stabilizing damping device includes a lower rail 1 installed on the ground and an upper rail 5 installed on the ceiling 6. The stacker crane is movably positioned between the lower rail 1 and the upper rail 5. A horizontal drive motor 3 and a drive motor controller are installed on the stacker crane. An L-shaped upper crossbeam 4 is installed on the vertical beam 2 of the stacker crane. A left-right horizontal damping mounting bracket 7 is installed on the L-shaped upper crossbeam 4. The damping mounting bracket 7 is located directly below the upper rail 5. The left end of the damping mounting bracket 7 is connected to a left brake installed along the direction of the upper rail 5. The first end of arm 8 is connected to the right end of damping mounting bracket 7, which is connected to the first end of right brake arm 9 along the direction of upper rail 5. A pull rod 13 is connected between the end of left brake arm 8 and the end of right brake arm 9. A damping brake wheel 10 is provided in the middle of left brake arm 8, and a guide wheel 11 is provided in the middle of right brake arm 9. The damping brake wheel 10 and the guide wheel 11 are clamped on the left and right sides of upper rail 5 respectively. An electromagnetic brake 12 is provided on the axle of damping brake wheel 10. The electromagnetic brake 12 is electrically connected to drive motor controller.

[0009] The left end of the damping mounting bracket 7 is hinged to the first end of the left brake arm 8 by a pin, and the right end of the damping mounting bracket 7 is hinged to the first end of the right brake arm 9 by another pin; a tension spring 14 and a tension nut 15 are provided on the pull rod 13.

[0010] Driven by the horizontal drive motor 3, the stacker crane runs on the lower track 1. When it needs to decelerate and stop, the lower part of the stacker crane stops moving forward under the action of the drive deceleration mechanism. At the same time, the electromagnetic brake 12 installed on the L-shaped upper crossbeam 4 is energized to generate braking force on the damping brake wheel 10, so that the damping brake wheel 10 and the upper track 5 generate braking friction, so that the upper and lower parts of the stacker crane stop running at the same time, thereby stabilizing the operation of the stacker crane.
