Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to the technical field of suspended ceiling shelves. Background Art

[0002] Modern factory buildings are generally high, and general industrial shelves cannot effectively utilize all the space. If the shelves are made higher, the load-bearing requirements of the columns will inevitably increase, thereby increasing the material cost of the shelves. The ceiling shelves can be directly riveted to the top of the steel structure without generating additional pressure on the shelves below. Therefore, on the basis of the existing industrial shelves, ceiling iron shelves can be installed in areas with a relatively suitable height in the warehouse to improve the utilization rate of the warehouse space.

[0003] Existing patent CN216393430U discloses a ceiling iron shelf, which can hang the shelf on the ground. The first column and the second column will directly separate after the rivet breaks due to various reasons. At this time, the shelf will directly fall, posing a safety hazard.

The first groove bar and the second groove bar are both vertically arranged U-shaped groove bars. The top end of the first groove bar is fixed to the top fixing member, and the first groove bar is inserted into the second groove body. The opening direction of the first groove bar is opposite to the opening direction of the second groove bar. A lower limit block is fixed on the first groove bar, and a part of the lower limit block is located inside the first groove bar. A detachable block is fixed inside the second groove bar. The upper limit block is located above the lower limit block, and a part of the lower projection of the upper limit block falls on the lower limit block. A vertically arranged anti-drop rod is fixed on the lower limit block, and a avoidance hole adapted to the anti-drop rod is provided on the upper limit block. The anti-drop rod passes through the avoidance hole. A plurality of through holes are provided on the bottom wall of the second slot, and the through holes are arranged vertically and equidistantly. At least one threaded hole is provided on the lower limit block, and each threaded hole is aligned with a through hole. The adjusting bolt passes through the through hole and is screwed on the threaded hole. The limit block is fixed to the bottom wall of the second slot by the adjusting bolt. The cargo support frame is horizontally arranged, and the cargo support frame is connected to all the columns.

[0006] Preferably, the cargo support frame consists of a frame, a load-bearing beam and a mesh. The frame is a rectangular frame. The four sides of the frame are not connected to each other. The sides of the frame are fixed to the columns. Several load-bearing beams are fixed inside the frame. Several meshes are laid flat on the combination of the frame and the load-bearing beams. The opposite side edges of the same mesh are bent downward to form limit plates. The two limit plates on the same mesh clamp the opposite outer walls of the frame.

[0007] Preferably, the lower limit block is fixed to the bottom wall of the first slot by bolts, the edge of the lower limit block is welded to the inner wall of the first slot, and the upper limit block is fixed to the bottom wall of the second slot body by bolts adapted to the through hole.

The column 2 has several roots, and the column 2 is vertically arranged. The column 2 is composed of a first groove bar 21, a second groove bar 22, a lower limit block 23, an upper limit block 24, and an adjusting bolt 28. The first groove bar 21 and the second groove bar 22 are both vertically arranged U-shaped groove bars. The top of the first groove bar 21 is fixed to the top fixing member 1, and the first groove bar 21 is inserted into the second groove body. The opening direction of the first groove bar 21 is opposite to the opening direction of the second groove bar 22. A lower limit block 23 is fixed on the first groove bar 21, and a part of the lower limit block 23 is located inside the first groove bar 21. A detachable upper limit block 24 is fixed inside the second groove bar 22, and the upper limit block 24 is located at the lower limit Above the positioning block 23, a part of the lower projection of the upper positioning block 24 falls on the lower positioning block 23. A vertically arranged anti-drop rod 25 is fixed on the lower positioning block 23. The upper positioning block 24 is provided with an avoidance hole 26 adapted to the anti-drop rod 25. The anti-drop rod 25 passes through the avoidance hole 26. The inner diameter of the avoidance hole 26 is slightly larger than the outer diameter of the anti-drop rod 25. A plurality of through holes 27 are provided on the bottom wall of the second slot 22. The through holes 27 are arranged vertically and equidistantly. At least one threaded hole is provided on the lower positioning block 23. Each threaded hole is aligned with a through hole 27. The adjusting bolt 28 passes through the through hole 27 and is screwed on the threaded hole. The positioning block is fixed to the bottom wall of the second slot 22 by the adjusting bolt 28. The cargo support frame 3 is horizontally arranged, and the cargo support frame 3 is connected to all the columns 2.

[0018] See Figure 4 The cargo support frame 3 is composed of a frame 30, a load-bearing beam and a mesh 31. The frame 30 is a rectangular frame. The four sides of the frame 30 are not connected to each other. The sides of the frame 30 are fixed to the columns 2. Several load-bearing beams are fixed inside the frame 30. Several meshes 31 are laid flat on the combination of the frame 30 and the load-bearing beams. The opposite side edges of the same mesh 31 are bent downward to form limit plates 32.
