Description

Technical Field

[0001] The present invention belongs to the technical field of smart fixing racks, and specifically is a stacking smart fixing rack for logistics storage. Background Art

[0002] Smart racks, also known as stacking racks, are a combination of pallets and shelves. Smart racks have uniform specifications and fixed capacity. When in use, goods can be directly stacked on the racks. With the help of forklifts, multi-layer stacking can be achieved to meet the needs of three-dimensional storage of single goods. It is easy to count and inventory in warehouses and is widely used in the logistics and warehousing industries.

[0003] At present, traditional smart racks all adopt a fixed structure with a constant storage capacity, which easily leads to space waste when storing smaller goods. Most smart racks are not equipped with roller sets, which makes it extremely difficult to store and retrieve goods, affecting the efficiency of storage operations. A few smart racks equipped with roller sets still require manual or machine assistance to push goods during use. Since the smart racks are light in weight, they are prone to displacement in the inventory, causing them to tip forward or backward.

DETAILED DESCRIPTION

[0039] See also Figure 1-Figure 8 In an embodiment of the present invention, a stacking type smart fixing rack for logistics storage includes: a frame 1;

[0040] The upper angle steel 11 and the lower angle steel 12 are both provided in two numbers, and each of the upper angle steels 11 is symmetrically fixed above the frame 1, and each of the lower angle steels 12 is symmetrically fixed below the frame 1;

[0041] The docking shaft 13 is vertically fixed at the four corners of the upper end surface of the frame 1, and the lower end surface of the frame 1 is provided with docking holes corresponding to the docking shaft 13; wherein in the stacking of multiple smart fixing frames, the upper and lower smart fixing frames 1 are placed opposite each other, at this time, the docking shaft 13 can be connected with the docking hole, and the lower angle steel 12 in the frame 1 of the upper smart fixing frame can be stacked on the upper angle steel 11 in the frame 1 of the lower smart fixing frame;

[0042] There are two transmission wheel frames 2, which are distributed in an upper and lower manner. Both of the transmission wheel frames 2 are slidably mounted in the frame 1;

[0043] A fixed frame 14 is vertically fixed on the frame 1, and a double-headed screw 15 is rotatably connected inside the fixed frame 14. A mounting seat 16 is fixed on each of the transmission wheel frames 2, and the mounting seat 16 is slidably connected with the double-headed screw 15 through threaded engagement; a lever adjustment sleeve 17 is fixed in the middle of the double-headed screw 15, so that a wrench tool can rotate and adjust the double-headed screw 15 through the lever adjustment sleeve 17; wherein, the two transmission wheel frames 2 can slide in opposite directions or opposite directions during the rotation adjustment of the double-headed screw 15, thereby changing the size of each storage space in the frame 1 and improving space utilization;

[0044] The transmission wheel frame 2 includes a front frame plate 21 and a rear frame plate 22, the front frame plate 21 and the rear frame plate 22 are both horizontally arranged and respectively installed on the front side and the back side of the frame 1, two first sliding sleeves 26 and two second sliding sleeves 27 are slidably connected to the frame 1, the two ends of the rear frame plate 22 are fixed to the second sliding sleeves 27, the two ends of the front frame plate 21 are connected to the first sliding sleeves 26, and a side rod 25 is transversely fixed between the first sliding sleeves 26 and the second sliding sleeves 27; two roller frames 3 are symmetrically connected to the rear frame plate 22, a plurality of rollers 4 are arranged on the roller frames 3, a plurality of bottom rods 24 are equidistantly distributed between the two roller frames 3, and the other ends of the roller frames 3 are rotatably connected to the front frame plate 21;

[0045] The roller frame 3 is set up in three different postures: horizontal, upward tilted or downward tilted, as the front frame plate 21 is adjusted up and down, so that the frame 1 can store, receive and deliver goods accordingly. By adjusting the angle of the roller frame, the storage and retrieval operation of goods can be completed quickly. For example, when receiving goods, the roller frame is adjusted to an upward tilted state, and the goods can slide in naturally; when delivering goods, the roller frame is adjusted to a downward tilted state, and the goods can slide out easily, avoiding the frame 1 from tipping over due to pushing the goods during storage and retrieval; and when the roller frame is in a horizontal state, it can be used as a stable storage platform to ensure that the goods are firmly placed on the plane.

[0046] In this embodiment, a guide rail 28 is vertically arranged on the first sliding sleeve 26, and both ends of the front frame plate 21 are slidably installed on the guide rail 28 respectively. An adjusting bolt is vertically rotatably connected to the first sliding sleeve 26, and the adjusting bolt is threadedly matched with the front frame plate 21, so that the front frame plate 21 can be slidably adjusted up and down. That is to say, when storing and retrieving goods, the front frame plate 21 is manually slidably adjusted up and down by adjusting the bolt, so that the roller frame 3 is correspondingly horizontal or inclined, thereby improving the efficiency of the storage and retrieval operation.

[0047] As a preferred embodiment, the upper angle steel 11 and the lower angle steel 12 are arranged in parallel or in an eight-shaped configuration, and the cross-sections of the lower angle steel 12 and the upper angle steel 11 are both in an inverted V-shaped structure;

[0048] The angle range of the upper angle steel 11 is between 90° and 135°, and the angle range of the lower angle steel 12 is between 80° and 110°; and the angle of the upper angle steel 11 is always greater than the angle of the lower angle steel 12, so that it can have a certain buffering protection effect to prevent gravity impact, etc. At the same time, it can enhance its bite effect and stacking bearing capacity and extend its service life.

[0049] In this embodiment, the roller frame 3 includes:

[0050] An outer packaging frame 31, one end of which is connected to the rear frame plate 22, and one side of the outer packaging frame 31 is parallelly connected to an inner packaging frame 32, and the inner packaging frame 32 and the outer packaging frame 31 are both rotatably connected to the rear frame plate 22;

[0051] Universal sleeves 33 are provided corresponding to the rollers 4. The universal sleeves 33 are arranged and fixed on the inner frame 32. One end of the roller 4 is universally rotatably connected to the universal sleeves 33 through a ball shaft.

[0052] The adapter sleeves 34 are arranged on the outer packaging frame 31 and correspond to the universal sleeves 33 one by one. Each adapter sleeve 34 is slidably adjustable on the outer packaging frame 31. An inner groove 41 is provided in the middle of the roller 4. A support rod 42 is slidably connected in the inner groove 41. One end of the support rod 42 is rotatably connected to the adapter sleeve 34. That is to say, when the rollers 4 are distributed in parallel, the rollers 4 can be normally rotated and connected to the outside of the support rod 42, thereby realizing the storage and retrieval of goods.

[0053] In this embodiment, a shaft frame 35 is slidably connected inside the outer frame 31, and one end of the shaft frame 35 is connected to the front frame plate 21;

[0054] Each of the adapter sleeves 34 is connected to a connecting rod 36, and two adjacent rollers 4 form a group. The ends of the two connecting rods 36 in each group of rollers 4 are hinged, and a guide rod 37 is vertically slidably connected to the outer frame 31, and one end of the guide rod 37 is connected to the hinged ends of the two connecting rods 36.

[0055] In this embodiment, the guide rod 37 controls the two rollers 4 to move closer or farther from each other through the connecting rod 36 under vertical sliding adjustment, so that the two rollers 4 are parallel or cross-distributed; when the rollers 4 are parallel, they can perform normal storage and retrieval operations on the goods, improving the storage and retrieval efficiency; and when the rollers 4 are cross-distributed, the rolling directions of the rollers 4 of each group are completely different, so that the goods can be prevented from sliding and falling due to slight vibration or external interference during storage, and stable storage of the goods can be achieved; and the cross-distributed rollers can better absorb vibrations and shocks from different directions, reducing the shaking of the goods during storage;

[0056] A pressing plate 38 is rotatably provided between each group of two rollers 4 on the outer frame 31, and the lower end of the pressing plate 38 is in contact with the upper end of the guide rod 37. A pin 39 is fixed on the shaft frame 35, and a guide groove is provided at the upper end of the pressing plate 38, and the pin 39 is slidably connected to the guide groove.

[0057] A spring is sleeved on the guide rod 37, and the spring pushes the guide rod 37 toward the pressure plate 38 through the elastic force. That is to say, as the shaft frame 35 slides out of the outer frame 31, it can push the pressure plate 38 to deflect counterclockwise through the sliding action of the pin 39 and the guide groove, so that the guide rod 37 slides downward, thereby changing the distribution posture of each group of rollers.

[0058] As a preferred embodiment, when the front frame plate 21 is fixed horizontally by adjusting bolts, the guide rod 37 can be pressed down by the pressure plate 38 and is in the lowest position. At this time, each group of rollers 4 crosses and abuts against each other, so that the rollers 4 on the roller frame 3 in a horizontal posture are distributed at multiple angles. That is to say, in the horizontal storage of goods, the roller frame 3 is in a horizontal state. At this time, the support rod 42 on each roller 4 is pulled by the connecting rod 36 and is cross-distributed. At this time, the goods can be stably stored on the roller frame 3; and in the cargo storage and retrieval operation, the corresponding roller frame 3 is in an upward or downward tilted state. At this time, the adapter sleeve 34 on each roller 4 slides and resets along the outer frame 31 and is distributed in parallel, thereby improving the storage and retrieval efficiency and facilitating the retrieval of goods.

[0059] In this embodiment, the cross section of the inner groove 41 in the roller 4 is a trapezoidal structure, and when the roller 4 is distributed at multiple angles, the support rod 42 is tightly engaged with the side wall of the inner groove 41, and the roller 4 does not roll at this time; further improving the stability of horizontal storage of goods and preventing the goods from falling due to the rolling of the roller;

[0060] The roller 4 is provided with an anti-skid rubber ring on its outer cover.

[0061] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
