Abstract
Description
Technical Field
[0001] This application relates to the field of logistics equipment technology, specifically to a clearing structure for the wheels of a logistics shuttle vehicle. Background Technology
[0002] In modern logistics and warehousing systems, logistics shuttles, as a highly efficient transportation device, are widely used for the handling and storage of goods. Logistics shuttles typically run along guide rails to achieve precise positioning and efficient transport. However, in actual operation, various debris, such as dust, chips, and small parts, inevitably accumulates on the guide rails. Once this debris enters between the wheels and the guide rails, it not only affects the normal operation of the shuttle, leading to accelerated wear on the wheels and unstable operation, but may even cause malfunctions, resulting in interruptions in cargo transportation and causing significant inconvenience and losses to logistics operations.
[0003] Currently, existing obstacle removal structures for logistics shuttle vehicles have many shortcomings. Some structures are too simple in design, failing to effectively remove debris from the guide rails, resulting in poor obstacle removal performance; others are too complex, increasing equipment cost and maintenance difficulty, while also reducing equipment reliability and stability. Utility Model Content

[0009] Preferably, the second support column has an L-shaped structure, and a reinforcing rod is connected between the upper and lower ends of the second support column, forming a triangular structure between the reinforcing rod and the second support column.
[0010] Preferably, both the front and rear ends of the second obstacle clearing guard plate are arc-shaped and integrally bent into shape.
[0011] Preferably, a second protective strip is adhered to the outer end face of the second obstacle clearing guard plate.
[0012] Preferably, the moving wheel set includes two hollow protective covers, one at the front and one at the back. The top of the protective cover is installed at the bottom of the shuttle base, and the bottom of the protective cover is open. Rollers are rotatably connected inside the protective cover via a rotating shaft. A dual-axis motor is installed at the bottom of the shuttle via a connecting plate.

By starting the dual-axis motor 17, the two rotating shafts 14 and the rollers 15 are driven to rotate, realizing the movement of the shuttle vehicle on the guide rail 3. The structure and principle of the dual-axis motor 17 are existing technologies.
[0030] A first guard plate assembly is symmetrically installed on the left and right sides of the shuttle base 1. The first guard plate assembly includes a first support column 4 installed on the front and rear sides of the side wall of the shuttle base 1.

[0032] Example 2:
[0033] like Figure 1 , 2 As shown in Figure 6, this utility model discloses another technical solution, a logistics shuttle vehicle walking wheel obstacle clearing structure, which differs from embodiment 1 in that the first obstacle clearing guard plate 5 includes a middle support plate 8 and two side corner guard plates 9. The corner guard plates 9 have an arc-shaped structure and are detachably fixed to the front and rear ends of the middle support plate 8 by bolts. The outer end faces of the corner guard plates 9 and the middle support plate 8 are both bonded with a first protective strip 10 to enhance the protective performance of the obstacle clearing guard plate.

[0039] This utility model provides a clearing structure for the wheels of a logistics shuttle. During use, the dual-axis motor 17 is started, driving the rotating shaft 14 and rollers 15 to rotate, causing the shuttle to move along the guide rail 3. During movement, the first clearing guard plate 5 and the second clearing guard plate 7 remove debris from the guide rail 3. The first protective strip 10 and the second protective strip 12 reduce wear between the guard plates and debris, and the guide wheels ensure the stability of the shuttle's operation. The wear of the first clearing guard plate 5 and the second clearing guard plate 7 is checked regularly. If the corner guard plate 13 is severely worn, it can be disassembled and replaced.
