Description

Technical Field

[0001] This utility model belongs to the field of logistics equipment technology, specifically relating to a single-arm cantilever outrigger. Background Technology

[0002] A double-layer conveyor is a conveying system consisting of two layers of conveyor belts, one above the other. It uses two parallel conveyor belts to simultaneously transport materials at different heights. This design allows the double-layer conveyor to complete more conveying tasks within the same space, significantly improving logistics efficiency.

[0003] Domestic utility model patent application number 202222233724.3 discloses an adjustable support frame for logistics conveying equipment. The frame includes a support body with placement slots at both ends of the bottom wall. Support plates are placed inside each of the two placement slots. Limiting holes are formed at all four ends of the support body. A U-shaped block is fixedly embedded at one end of each of the four limiting holes. Support rods are movably inserted through each of the four U-shaped blocks, with one end of each support rod movably inserted into one of the four limiting holes. This design, by providing a support frame with placement slots at both ends of the bottom wall and support plates placed inside each of the two placement slots, allows for adjustment of the distance between the two support plates by pulling them. This adjusts the total length of the support frame and the two support plates, thus enabling support for logistics conveying equipment of different lengths. The aforementioned utility model is a support bracket for a logistics conveyor line, while this utility model is a conveyor line support leg. In the support and installation of double-layer conveyor equipment, when other equipment is connected to the upper side and the width of the upper equipment is greater than that of the lower equipment, ordinary equipment support legs cannot provide support. Therefore, a single-arm cantilever support leg is the most suitable support structure. However, even with a single-arm cantilever support leg, there is still a possibility of unstable support during use. Furthermore, when the upper equipment conveys heavy objects, it can easily affect the structure of the support leg itself. If the connecting structure cannot support the pressure of a heavy object, the support leg may collapse or bend, thus affecting the use of the double-layer conveyor equipment. Utility Model Content

[0027] This specific embodiment is a single-arm cantilever support leg.

[0028] The aforementioned utility model is a support bracket for a logistics conveyor line, while this utility model is a conveyor line support leg. In the support and installation of double-layer conveyor equipment, when other equipment is connected to the upper side and the width of the upper equipment is greater than that of the lower equipment, ordinary equipment support legs cannot provide support. Therefore, a single-arm cantilever support leg is the most suitable support structure. However, even with a single-arm cantilever support leg, there is still a possibility of unstable support during use. Furthermore, when the upper equipment conveys heavy objects, it can easily affect the structure of the support leg itself. If the connecting structure cannot support the pressure of a heavy object, the support leg may collapse or bend, thus affecting the use of the double-layer conveyor equipment.

[0029] Its structural diagram is as follows Figures 1-4 As shown, a single-arm cantilever outrigger includes a long boom 1 and a short boom 11 on one side. Both the long boom 1 and the short boom 11 have multiple sets of mounting holes 13, and adjustable bases 15 are installed at the bottom of both. The multiple sets of mounting holes 13 facilitate the connection and installation of other structures with the long boom 1 and the short boom 11. Adjustment grooves are provided on the inner side of the bottom of both the long boom 1 and the short boom 11. Base plates 14 are welded to the bottom of both the long boom 1 and the short boom 11. The adjustable base 15 is installed on the outside of the long boom 1 and the short boom 11, and is connected to the base plate 14 by an adjustable screw 17. The adjustable screw 17 is threaded through the base plate 14, and the adjustable base 15 is positioned and installed with the long boom 1 and the short boom 11 by fixing bolts 16. Adjust the adjustable base 15 according to the required transmission height of the equipment. Adjust the height between the adjustable base 15 and the base plate 14 by rotating the adjustable screw 17. After the adjustment is completed, install the fixing bolt 16 to fix the position of the adjustable base 15.

[0030] The long boom 1 and short boom 11 are connected and installed via a support frame 21. The top of the short boom 11 is connected and installed to the long boom 1 via a load-bearing base frame 2. Mounting plates 25 are welded and installed at both ends of the support frame 21 and one end of the load-bearing base frame 2, and are installed by mounting bolts 12 through the mounting plates 25 and mating with mounting holes 13. Two sets of mounting rings 22 are snapped and installed at the bottom of the load-bearing base frame 2. The load-bearing base frame 2 is mated and installed with the conveying equipment at the bottom via the mounting rings 22. The short boom 11 mainly supports it, and the long boom 1 provides auxiliary lifting and support. A load-bearing top frame 23 is fixedly installed on the top of the long boom 1. The load-bearing top frame 23 and the long boom 1 are fixedly installed via mounting clamps 4, and the bottom of the load-bearing top frame 23 and one side of the long boom 1 are supported and connected by diagonal bracing 3.

[0031] The supporting top frame 23 has multiple sets of docking holes 24. Supporting seats 5 are mounted on the supporting top frame 23 via two sets of mounting rings 22. The two ends of the diagonal brace 3 are connected to the docking holes 24 and mounting holes 13 respectively via mounting bolts 12 through the positioning plate 31. The supporting seats 5 mounted on the mounting rings 22 support the top conveying equipment. The diagonal brace 3 supports the bottom of the supporting top frame 23, increasing the stability of the top of the supporting top frame 23. The mounting clamp 4 includes a docking plate 41 mounted on the top of the supporting top frame 23, an auxiliary plate 43 that penetrates the long arm 1 and fits against the bottom of the supporting top frame 23, and four sets of docking bolts 42 that penetrate the docking plate 41 and the auxiliary plate 43 for docking. The connecting plate 41 and the auxiliary plate 43 are connected and installed by four sets of connecting bolts 42, which provides strong support for the load-bearing top frame 23 and the short boom 11. Through the clamping of the connecting plate 41 and the auxiliary plate 43, the upper load-bearing top frame 23 and the long boom 1 are effectively clamped together, avoiding the shaking between the load-bearing top frame 23 and the long boom 1 during use.

[0032] A welding frame 45 is welded to one side of the bottom of the auxiliary plate 43, and a snap-fit ​​plate 44 is welded to one end of the welding frame 45. The snap-fit ​​plate 44 has a snap-fit ​​groove 46, which snaps and positions the long boom 1. By snapping and positioning the snap-fit ​​plate 44 with the outer side of the long boom 1 through the snap-fit ​​groove 46 on the snap-fit ​​plate 44, when the conveyed object is heavy during the equipment transfer process on the top of the supporting frame 23, the supporting frame 23 may collapse due to the strong external pressure. In this case, the snap-fit ​​plate 44 and the welding frame 45 act on the side of the long boom 1 to relieve the pressure on the supporting frame 23, thereby ensuring the stability of the outrigger support.

[0033] First, move the outrigger to the desired installation position. Rotate the adjustable screw 17 according to the required transmission height of the equipment to limit the height of the long boom 1 and short boom 11. Then, install the load-bearing base frame 2 and support frame 21 by mounting bolts 12 through the mounting plate 25 and aligning them with the mounting holes 13 on the long boom 1 and short boom 11. After installation, align the conveying equipment on top of the load-bearing base frame 2 with the mounting ring 22. First, place the auxiliary plate 43 through the long boom 1. Then, align the diagonal brace 3 with the long boom 1, and then install the load-bearing top frame 23 on top of the long boom 1. Finally, fix the connecting plate 41 and auxiliary plate 43 with connecting bolts 42.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
