Description

Technical Field

[0001] This utility model relates to stacker crane technology, specifically a horizontal guide wheel structure for a stacker crane. Background Technology

[0002] Stacker cranes are warehousing equipment used in warehouses, workshops, and other locations to grab, move, and stack unit goods or pick up and place unit goods from high-rise shelves. They shuttle through warehouse aisles to transport goods to designated storage locations. Two horizontal guide wheels are directly fixed to the end of the lower crossbeam of the stacker crane. These two horizontal guide wheels clamp the two sides of the ground rail to prevent the lower crossbeam from derailing.

[0003] However, during actual operation, the stacker crane is subjected to uneven lateral impact forces on both sides, which leads to increased wear and deformation of the horizontal guide rollers, resulting in increased operating noise and even rail jamming. Therefore, it is necessary to provide a horizontal guide roller structure that can quickly replace the guide rollers. Utility Model Content

[0021] Example 1: like Figure 1-2 As shown, a horizontal guide wheel 8 structure for a stacker crane is provided at the end of the lower crossbeam. It includes a mounting frame, which is installed at the end of the lower crossbeam. Both ends of the mounting frame are provided with fixing grooves, and fixing plates 6 are provided in the fixing grooves. Both sides of the fixing plates 6 are provided with protruding plates, and fixing bolts 10 are passed through the protruding plates. The fixing bolts 10 are threadedly engaged with threaded holes. The threaded holes are opened on both sides of the fixing grooves. The fixing bolts 10 fix the protruding plates to the mounting frame. A wheel axle 7 is provided below the fixing plate 6. A bearing 9 is sleeved on the wheel axle 7. The outer ring of the bearing 9 is fitted with a horizontal guide wheel 8. A threaded rod 12 is provided above the wheel axle 7.

[0023] The stacker crane structure of this embodiment uses a horizontal guide wheel 8, which allows for quick disassembly and assembly of the fixing plate 6 via the fixing bolts 10 and loosening of the locking nut 11, enabling the damaged horizontal guide wheel 8 to be quickly removed from the fixing plate 6 and replaced.

[0024] The mounting bracket includes a vertical plate 1 and a bottom plate 2. The bottom plate 2 is fixed to one side of the bottom end of the vertical plate 1, the vertical plate 1 is fixed to the end of the lower crossbeam, the fixing groove is provided in the vertical plate 1, and the threaded hole is located in the vertical plate 1; wherein the vertical plate 1 and the bottom plate 2 are L-shaped.

[0025] The base plate 2 is provided with a baffle 3 on the side opposite to the vertical plate 1; the baffle 3 is provided with an anti-collision block on the side away from the vertical plate 1; a reinforcing plate 4 is provided between the baffle 3 and the vertical plate 1; the baffle 3 is used to protect the fixing plate 6 and the threaded rod 12, the anti-collision block is used to protect the baffle 3 and prevent the baffle 3 from deforming due to impact, and the reinforcing plate 4 is used to improve the strength of the baffle 3 and further prevent the baffle 3 from deforming and being damaged.

[0026] The bearing 9 is a roller bearing 9; the roller bearing 9 can withstand both radial and axial forces at the same time, has better adaptability, and has a long service life.

[0027] Both ends of the bottom of the vertical plate 1 are provided with hooks 13; the hooks 13 are detachably installed at the bottom of the vertical plate 1 by means of locking bolts 14 and locking nuts, and the hooks 13 are used to hook the ground rail to prevent the lower crossbeam from detaching from the ground rail.

[0028] The threaded rod 12 is eccentrically positioned with respect to the wheel axle 7. When the threaded rod 12 rotates, the wheel axle 7 rotates eccentrically, thereby adjusting the contact gap between the guide wheel 8 and the track, adapting to track wear or installation errors, and maintaining the stability of the stacker crane operation.
