Description

TECHNICAL FIELD

[0001] The utility model relates to the field of beam type goods shelves, in particular to a beam type goods shelf. BACKGROUND

[0002] With the high-speed development of modern industry and logistics industry, the beam type goods shelf as the core equipment of the warehousing system has been widely used in the stereoscopic storage of various materials. In the prior art, modular structure design is generally adopted to adapt to different goods forms, and a typical structure comprises two oppositely arranged support frames and a placing frame arranged between the two support frames. Taking a beam type goods shelf convenient to adjust with the application number CN202421643663.0 as an example, the shelf is combined by the support frame (comprising a stable frame composed of a vertical column and a horizontal diagonal support) and the placing frame (comprising a beam and a cross beam), in order to realize the differential storage of barrel-shaped goods and pallet goods. At present, the cross beam in some similar shelves is designed to be replaceable: when storing barrel-shaped goods, a welded fixed angle iron is used as the cross beam to form stable support by using the inclined surface thereof; when storing pallets or boxes, a rectangular square tube with U-shaped block clamping at both ends is used as the cross beam to bear the plane.

[0003] However, it is found in actual use that such replaceable structure has the following significant technical defects: first, the angle iron and the square tube belong to different structures, so that the cross beam needs to be disassembled and reassembled as a whole when being replaced, resulting in low efficiency of warehouse layout adjustment; second, the welded fixed angle iron and the clamped square tube cannot coexist in the same shelf, which is not suitable for mixed warehouse scenes where barrel-shaped goods and pallet goods need to be stored at the same time; third, frequent replacement of the cross beam is easy to cause wear of the cross beam connection part, which has the potential safety hazard of reducing the stability of the whole shelf.

[0034] In combination Figures 2-7 As shown, as the core technical concept of the utility model, the bearing mechanism 3 includes fixed beam 31 and movable beam 32, the two ends of fixed beam 31 are provided with cross-connection structure 33 connected with beam 2, the middle part is provided with opening 311 along the length direction, and the two sides of the opening 311 of the two ends are provided with vertical sliding groove 312 and horizontal clamping groove 313 communicated with the upper part of sliding groove 312, the two ends of movable beam 32 are provided with guide protrusion 34 slidably matched with sliding groove 312 and clamping groove 313, and the adjacent side surfaces of adjacent two movable beams 32 are inclined surfaces 321 extending upwards away from each other, i.e. Figure 9 As shown, the adjacent side surfaces of adjacent two movable beams 32 are trumpet-shaped with opening 311 upwards, so as to form barrel-shaped goods limiting space, and the storage of barrel-shaped goods is as follows Figure 8 As shown.

[0035] Wherein clamping groove 313 is located at the upper part of sliding groove 312, during use, guide protrusion 34 can be lowered to the first working position along sliding groove 312, so that the upper side of movable beam 32 is flush with the upper side of fixed beam 31 or the upper side of movable beam 32 is lower than the upper side of fixed beam 31 (such as Figures 2-3 , at this time, the upper side of movable beam 32 is flush with the upper side of fixed beam 31) or the second working position (such as Figures 5-7 , guide protrusion 34 moves upwards from the first working position and turns into clamping groove 313, so that the upper side of movable beam 32 is higher than the upper side of fixed beam 31), so that the mixed storage of barrel-shaped goods and pallet goods is realized by adjusting the position of movable beam 32 in sliding groove 312 and clamping groove 313 of fixed beam 31.

[0036] Specifically, in combination Figures 2-4 When storing pallet goods, guide protrusion 34 is moved downwards along sliding groove 312 on fixed beam 31 to the bottom of sliding groove 312, at this time, if the upper side of movable beam 32 is flush with the upper side of fixed beam 31, the pallet goods are placed on the upper side of fixed beam 31 and movable beam 32, and if the upper side of movable beam 32 is located inside fixed beam 31, the pallet goods are placed on the upper side of fixed beam 31.

[0037] When storing barrel-shaped goods, in combination Figures 5-7 , guide protrusion 34 is moved upwards from the bottom of sliding groove 312 and then continues to move horizontally along clamping groove 313 to the bottom of clamping groove 313, at this time, the upper side of movable beam 32 is higher than the upper side of fixed beam 31, and the barrel-shaped goods are placed between the adjacent side surfaces of adjacent two movable beams 32, from Figure 8It can be seen that the two sides of the barrel-shaped goods are supported by the adjacent side surfaces of the two adjacent movable beams 32, and the two ends of the lower side of the barrel-shaped goods are placed on the cross beam 2. Of course, the lower side of the barrel-shaped goods can also be in a suspended state and be supported only by the two movable beams 32.

[0038] Specifically, in combination with Figure 3 and Figure 6 , the clamping groove 313 extends outward from the upper part of the sliding groove 312 and is arranged towards the lower side of the fixed beam 31. The clamping grooves 313 on the fixed beam 31 are of the same specification and are arranged in parallel.

[0039] The bridging structure 33 includes a U-shaped clamping plate 331 and a locking bolt. The U-shaped clamping plate 331 is wrapped around the outer side surface of the cross beam 2 with the downward U-shaped opening 311, and is fixed by the locking bolt. The design of fixing the U-shaped clamping plate 331 on the cross beam 2 by the locking bolt can be selected according to actual needs, and the related connection structure of the locking bolt is not shown in the figure.

[0040] The fixed beam 31 of the embodiment is a channel steel, and the upper side surface thereof is flush with the upper side surface of the U-shaped clamping plate 331, so that the U-shaped clamping plate 331 can also provide support for the goods during storage of the goods.

[0041] The two end surfaces of the fixed beam 31 are located at the middle part of the outer side surface of the U-shaped clamping plate 331 on the same side, and are welded to the outer side surface of the U-shaped clamping plate 331 on the same side.

[0042] The guide protrusion 34 of the embodiment is a cylindrical structure arranged on the movable beam 32.

[0043] The movable beam 32 of the embodiment is an equal angle iron with an L-shaped cross section. The lower part of each side edge of the equal angle iron is provided with a guide protrusion 34 (as shown in Figure 4 and Figure 7 During processing, the guide protrusion 34 can be arranged on the lower outer side of the side surface of the equal angle iron, can be directly welded to the lower side of the movable beam 32, or can be first drilled on the lower part of the side surface of the equal angle iron, then the guide protrusion 34 is inserted into the hole, and finally the side surface of the equal angle iron is welded along the outer circle of the guide protrusion 34.

[0044] Of course, in some cases, a guide protrusion 34 can also be directly welded to the lower part of each side edge of the equal angle iron, which is equivalent to the above-mentioned mode of designing two guide protrusions 34 located at the lower part of the side surface of the equal angle iron as one whole guide protrusion 34.

[0045] In some cases, the top of the movable beam 32 is also provided with a flat surface to improve the support surface for supporting tray-type goods. For example, the upper part of the equal angle iron is processed as a flat surface based on the above design.

[0046] In order to improve the limit of the two working positions of the guide protrusion 34, the groove bottoms of the sliding groove 312 and the clamping groove 313 are arc-shaped and matched with the guide protrusion 34, and the clamping groove 313 is an arc-shaped groove.

[0047] In the embodiment, the height difference between the upper surface of the fixed beam 31 and the top of the movable beam 32 is not greater than the depth of the opening 311 of the fixed beam 31, so that when the guide protrusion 34 moves along the sliding groove 312 to the first working position, the upper side of the movable beam 32 is flush with or lower than the upper side of the fixed beam 31, so as not to hinder the storage of the tray type goods.
