[0004] The shuttle rack guide rails can be adjusted to accommodate shuttles of different widths by adjusting the spacing between the two rails, but it still cannot control the problem of the shuttle deviating from its path when it is moving. Utility Model Content

[0005] The purpose of this utility model is to provide a pallet rack trolley anti-detachment structure, which can provide left and right and up and down limits for the shuttle trolley to move on the rack, and prevent the shuttle trolley from deviating from the existing route.

[0006] To achieve the above objectives, this utility model provides a pallet rack trolley anti-detachment structure, which includes a trolley track and a shuttle. The trolley track has inwardly protruding guide strips on both sides, and a support plate for the shuttle to roll is provided on both sides of the bottom of the trolley track. The support plate and the guide strips are connected by side plates. An open layer is provided in the middle of the shuttle, and right-angle holes are provided at the four corners of the open layer. A fixed shaft is provided in the middle of the open layer, and cross-arranged movable arms are sleeved on the fixed shaft. Limiting guide wheels are provided at the outer ends of the movable arms, and annular grooves are provided around the limiting guide wheels to roll in contact with the guide strips. The movable arms on both sides are connected to a driving mechanism that drives their opening and closing. The driving mechanism pulls the limiting guide wheels on both sides to extend out on the first or second side perpendicular to the right-angle holes.

[0007] Preferably, the driving mechanism includes a drive motor installed at the front or rear end of the overhead layer; the drive motor shaft is connected to a lead lever, a slider that slides back and forth is provided in the overhead layer, and a lead screw nut that is threadedly engaged with the lead lever is provided on the slider; both ends of the slider are provided with connecting rods that are hinged to the adjacent movable arms.

[0008] Preferably, the two movable arms have clearance grooves on their sides facing each other at the middle; the depth of the clearance grooves is half the thickness of the movable arms; the movable arms have rectangular holes on their sides for inserting the connecting rods, and a first pin is provided in the rectangular holes for rotatably connecting with the connecting rods.

[0009] Preferably, the slider has notches at both ends; a second pin is provided in the notch and is rotatably connected to the connecting rod.

[0010] Preferably, a bearing seat is provided inside the overhead layer, and the inner end of the screw lever is rotatably connected to the bearing seat.

[0011] Preferably, a mesh plate is provided between the two bearing plates.

[0012] Preferably, the shuttle is a two-way shuttle or a four-way shuttle.

[0013] According to the above technical solution, this utility model provides a pallet rack trolley anti-detachment structure, which includes a trolley track and a shuttle. The trolley track has inwardly protruding guide strips on both sides, and the bottom of the trolley track has a support plate for the shuttle to roll on both sides. The support plate and the guide strips are connected by side plates. The shuttle has an open layer in the middle, and right-angle holes are provided at the four corners of the open layer. A fixed shaft is provided in the middle of the open layer, and cross-arranged movable arms are sleeved on the fixed shaft. The outer end of the movable arm is provided with a limiting guide wheel, and the periphery of the limiting guide wheel is provided with an annular groove that rolls in contact with the guide strip. The movable arms on both sides are connected to a drive mechanism that drives them to open and close. The drive mechanism pulls the limiting guide wheels on both sides to extend out on the first or second side that is perpendicular to the right-angle holes.

[0014] The usage and benefits of this pallet racking trolley anti-derailment structure are as follows: The shuttle trolley is placed on the support plates on both sides and moves to transport goods on the rack. During transportation, the drive mechanism drives the movable arm to rotate around a fixed axis and open to both sides, allowing the four limit guide wheels on both sides to contact their corresponding guide protrusions. The guide protrusions extend into the annular grooves, thereby limiting the left, right, and up and down positions, effectively preventing the shuttle trolley from deviating from its original route and causing goods to collide with the racks on both sides. When the limit guide wheels are not needed, the movable arm can be retracted inward to extend diagonally opposite the shuttle trolley, allowing the limit guide wheels to be stored in the open layer.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0025] See Figure 1-4 The pallet rack trolley anti-detachment structure shown includes a trolley track and a shuttle 4. The trolley track has inwardly protruding guide strips 2 on both sides. The bottom of the trolley track has support plates 7 on both sides to allow the shuttle 4 to roll. The support plates 7 are connected to the guide strips 2 via side plates 1. A raised layer 8 is provided in the middle of the shuttle 4. Right-angle holes 5 are provided at the four corners of the raised layer 8. A fixed shaft 14 is provided in the middle of the raised layer 8. Cross-shaped movable arms 9 are sleeved on the fixed shaft 14. Limiting guide wheels 6 are provided at the outer ends of the movable arms 9. An annular groove 19 is provided around the limiting guide wheels 6 to roll in contact with the guide strips 2. The movable arms 9 on both sides are connected to a drive mechanism that drives their opening and closing. The drive mechanism pulls the limiting guide wheels 6 on both sides to extend out from the first or second side perpendicular to the right-angle holes 5.

[0026] By implementing the above technical solution, the shuttle 4 is placed on the support plates 7 on both sides and moves to transport goods on the shelves. During transportation, the drive mechanism drives the movable arm 9 to rotate around the fixed shaft 14 and open to both sides, so that the four limiting guide wheels 6 on both sides can contact the corresponding guide protrusions 2. The guide protrusions 2 extend into the annular groove 19, thereby achieving left-right and up-down position limiting, effectively preventing the shuttle 4 from deviating from the existing route during operation and causing the goods to collide with the shelves on both sides. When the limiting guide wheels 6 are not needed, the movable arm 9 can be retracted inward to extend diagonally with the shuttle 4, so that the limiting guide wheels 6 are stored in the open layer 8. This pallet racking trolley anti-detachment structure can handle guide protrusions 2 with different spacing by controlling the opening angle of the movable arm 9, making it more applicable.

[0027] In this embodiment, to further provide a driving mechanism, the driving mechanism includes a drive motor 15 installed at the front or rear end of the overhead layer 8; the drive motor 15 is shaft-connected to a lead lever 10; a slider 11 that slides back and forth is provided inside the overhead layer 8; a lead screw nut 21 that is threadedly engaged with the lead lever 10 is provided on the slider 11; and connecting rods 13 that are hinged to the adjacent movable arms 9 are provided at both ends of the slider 11. The driving method of this driving mechanism is as follows: the drive motor 15 rotates forward, and under the threaded rotational engagement of the lead lever 10 and the lead screw nut 21, the slider 11 moves along the length direction of the trolley track inside the overhead layer 8, and under the linkage of the connecting rods 13 on both sides, pushes the movable arms 9 on both sides to open to both sides. To prevent the slider 11 from rotating along with the trolley, the thickness of the slider 11 is set to be the same as the height of the overhead layer 8.

[0028] In this embodiment, the two movable arms 9 have clearance grooves 18 on their facing sides at the middle; the depth of the clearance grooves 18 is half the thickness of the movable arm 9; the movable arm 9 has a rectangular hole 20 on its side for inserting the connecting rod 13, and a first pin 17 rotatably connected to the connecting rod 13 is disposed in the rectangular hole 20. This arrangement ensures that the connection points of the two movable arms 9 fit together, and that the upper and lower sides of both ends of the movable arms 9 are flush, thereby allowing the four limiting guide wheels 6 to be at the same height.

[0029] In this embodiment, the slider 11 has notches at both ends; a second pin 16, which is rotatably connected to the connecting rod 13, is disposed in the notch. With this arrangement, one end of the connecting rod 13 rotates around the second pin 16, and the other end of the connecting rod 13 rotates around the first pin 17.

[0030] In this embodiment, a bearing seat 12 is provided within the overhead layer 8, and the inner end of the wire lever 10 is rotatably connected to the bearing seat 12. This arrangement rotatably connects the inner end of the wire lever 10 to the bearing seat 12, thereby improving the support stability of the wire lever 10.

[0031] In this embodiment, a mesh panel 3 is provided between the two supporting plates 7. This arrangement prevents items from falling below, thus improving safety.

[0032] In this embodiment, the shuttle 4 is a two-way shuttle or a four-way shuttle. When the shuttle 4 is a four-way shuttle, the movement distance of the slider 11 can control whether the limiting guide wheel 6 extends from the first side or the second side of the right-angle hole 5, so as to adapt to the rolling cooperation between the limiting guide wheel 6 and the guide protrusions 2 on the corresponding two sides after the shuttle 4 changes direction.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0035] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
