Description

Technical Field

[0001] This utility model belongs to the field of shelving technology, specifically relating to a narrow aisle pallet racking mechanism. Background Technology

[0002] Shelving is generally used as a storage tool for stacking and classifying goods in multiple layers. It is commonly used in logistics warehouses, supermarket shelves, and other places. Narrow aisle pallet racking is mainly used in aisles where the spacing between racks is narrow, so as to facilitate the movement of racks and the adjustment of the position between racks, making it convenient for the storage of goods.

[0003] Existing narrower pallet racks are typically designed to be narrow and long to fit into narrow aisle spaces. When a forklift lifts and moves the racks, the narrow racks have less contact surface with the forklift, and the inertia generated by braking or accelerating during movement can easily cause the racks to sway, tilt, or even tip over. This results in poor stability, and the racks cannot be adjusted to be horizontal or vertical according to the width of the aisle, which can easily cause the moving racks to rub or collide with the fixed racks on both sides. Utility Model Content

[0004] The purpose of this invention is to provide a narrow aisle pallet racking mechanism that can use the pressure of a forklift shovel rising to make the side plates fit against the sides of the forklift shovel, thereby limiting and fixing the racking and preventing it from shaking during movement.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A narrow aisle pallet racking mechanism includes four support frames, with a plurality of placement plates assembled between the four support frames. A base plate is fixedly connected to the bottom of each support frame, and a limit plate is provided on the lower side of the base plate. A housing is fixedly connected to the bottom surface of the limit plate, and a rotating component is provided inside the housing. Two limit components are symmetrically arranged on the front and back of the bottom surface of the limit plate.

[0007] Two arc-shaped blocks are fixedly connected to the bottom surface of the base plate, and two arc-shaped grooves are opened on the top surface of the limiting plate. The arc-shaped blocks are slidably connected to the arc-shaped grooves, and the two arc-shaped grooves are concentric.

[0008] The rotating assembly includes a motor fixedly connected to the bottom surface of the inner cavity of the housing. The output shaft of the motor is fixedly connected to a first gear. The bottom surface of the base plate is fixedly connected to a transmission shaft. The bottom end of the transmission shaft passes through a limiting plate and is fixedly connected to a second gear. The first gear meshes with the second gear.

[0009] The limiting assembly includes a movable rod movably connected to the top surface of the base plate. The bottom end of the movable rod passes through the limiting plate and is fixedly connected to a pressure plate. A spring is sleeved on the side wall of the movable rod between the pressure plate and the limiting plate. Two clamping plates are slidably connected to the bottom surface of the limiting plate about the movable rod as the axis of symmetry. Steel wires are fixedly connected to the opposite side walls of the clamping plates. Through holes are opened on the bottom surfaces of the base plate and the limiting plate. The steel wires pass through the through holes and are fixedly connected to the side wall of the movable rod near the top.

[0010] Each through hole sidewall is rotatably connected to a guide wheel, and the steel wire abuts against the guide wheel.

[0011] The bottom surface of the limiting plate has two sliding grooves with the movable rod as the axis of symmetry. The top surface of the clamping plate is fixedly connected with a slider, and the slider is slidably connected to the sliding groove.

[0012] Each pressure plate has a rubber pad fixedly connected to its bottom surface.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a narrow aisle pallet racking mechanism. Through the cooperation of the base plate, limiting plate, rotating component, and other components, when the forklift shovel contacts the bottom of the pressure plate, the upward pressure of the forklift shovel can make the two side clamps fit against the sides of the forklift shovel, which plays a role in limiting and fixing, and prevents the racking from shaking, tilting or tipping over during movement. In addition, the rotating component can be used to adjust the horizontal or vertical direction of the racking to adapt to different widths of racking spacing, thereby improving the stability of the racking during movement.

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-6 As shown, a narrow aisle pallet racking mechanism includes four support frames 1, several placement plates 2 are assembled between the four support frames 1, a base plate 3 is fixedly connected to the bottom of the support frame 1, a limit plate 4 is provided on the lower side of the base plate 3, a housing 5 is fixedly connected to the bottom surface of the limit plate 4, a rotating component is provided inside the housing 5, and two limit components are symmetrically arranged on the front and back of the bottom surface of the limit plate 4.

[0025] Two arc-shaped blocks 20 are fixedly connected to the bottom surface of the base plate 3, and two arc-shaped grooves 21 are opened on the top surface of the limiting plate 4. The arc-shaped blocks 20 and the arc-shaped grooves 21 are slidably connected, and the two arc-shaped grooves 21 are concentric.

[0026] like Figure 2 and Figure 5 As shown, the rotating assembly includes a motor 6 fixedly connected to the bottom surface of the inner cavity of the housing 5. The output shaft of the motor 6 is fixedly connected to a first gear 7. The bottom surface of the base plate 3 is fixedly connected to a transmission shaft 9. The bottom end of the transmission shaft 9 passes through the limiting plate 4 and is fixedly connected to a second gear 8. The first gear 7 and the second gear 8 mesh.

[0027] By setting up a rotating component to allow the overall angle of the shelf to change, if the distance between the shelves on both sides is small, the space occupied by the left and right sides of the shelf can be adjusted to allow the shelf to move in a narrow space, avoiding friction or collision with the shelves on both sides, thereby improving its practicality.

[0028] like Figure 3 and Figure 6As shown, the limiting assembly includes a movable rod 10 movably connected to the top surface of the base plate 3. The bottom end of the movable rod 10 passes through the limiting plate 4 and is fixedly connected to a pressure plate 11. A spring 12 is sleeved on the side wall of the movable rod 10 between the pressure plate 11 and the limiting plate 4. Two clamping plates 13 are slidably connected to the bottom surface of the limiting plate 4 about the movable rod 10 as an axis of symmetry. Steel wires 14 are fixedly connected to the opposite side walls of the clamping plates 13. Both the base plate 3 and the limiting plate 4 have through holes 15 on their bottom surfaces. The steel wires 14 pass through the through holes 15 and are fixedly connected to the side wall of the movable rod 10 near the top. Rubber pads 19 are fixedly connected to the bottom surface of the pressure plate 11. The rubber pads 19 can increase the friction between the pressure plate and the forklift shovel, and at the same time protect the pressure plate 11.

[0029] Specifically, the width of the pressure plate 11 is greater than the width of the forklift shovel. On the one hand, this allows the forklift shovel to accurately lift the pressure plate 11, and on the other hand, it can limit the movement of the clamping plates 13 on both sides. When the forklift shovel lifts the pressure plate 11 to its highest position, the clamping plates 13 on both sides abut against the side wall of the pressure plate 11, so that the outer perimeter of the forklift shovel forms an inverted U-shaped structure, avoiding instability caused by the forklift shovel deviating.

[0030] like Figure 6 As shown, guide wheels 16 are rotatably connected to the sidewalls of the through hole 15, and the steel wire 14 abuts against the guide wheels 16.

[0031] By setting the guide wheel 16, the friction of the steel wire 14 can be reduced, avoiding hard friction between the steel wire 14 and the through hole 15, which can improve the durability and service life of the steel wire 14.

[0032] like Figure 6 As shown, the bottom surface of the limiting plate 4 has two sliding grooves 18 with the movable rod 10 as the axis of symmetry. The top surface of the clamping plate 13 is fixedly connected to the slider 17, and the slider 17 is slidably connected to the sliding groove 18. The connection between the clamping plate 13 and the sliding groove 18 through the slider 17 can limit the clamping plate 13 and ensure that the clamping plate 13 always moves in the horizontal direction. In addition, an elastic structure can be added in the sliding groove 18 to assist the clamping plate 13 in resetting.

[0033] The working principle of this utility model is as follows: When the rack needs to be moved, the forklift shovel first inserts into the bottom of the rack and is located under the pressure plate 11. Then, the forklift shovel rises and contacts the pressure plate 11, causing the pressure plate 11 to move upward. At the same time, the spring 12 is compressed, and the pressure plate 11 drives the steel wire 14 to move upward through the movable rod 10. The steel wire 14 pulls the clamps 13 on both sides to move towards the pressure plate 11, so that the clamps 13 are in contact with the sides of the forklift shovel, increasing the stability of the rack on the forklift shovel and avoiding swaying or displacement. During the movement of the rack, if the distance between the racks placed on both sides is small, the motor 6 can be started to drive the first gear 7 to rotate. The first gear 7 meshes with the second gear 8 and drives the transmission shaft 9 to rotate. The transmission shaft 9 drives the rack to rotate through the base plate 3, causing the rack to rotate 90°, changing from a horizontal position to a vertical position, reducing the space occupied by the rack, thereby improving its stability during movement.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
