Description

Technical Field

[0001] This utility model relates to the technical field of construction equipment, specifically a material rack for construction. Background Technology

[0002] Construction material racks are temporary structures used on construction sites to store, store, and manage building materials, tools, and equipment. They are crucial for improving construction efficiency, ensuring construction safety, and reducing the risk of accidents. Material racks are used to store various construction materials, such as pipes, blocks, steel bars, timber, tools, and other small items, ensuring a clean and orderly construction site. Typically, after the material racks are filled with materials, two racks in each group need to be stacked for easy transport.

[0003] Utility model patent CN222222589U discloses a material rack for construction, belonging to the technical field of construction equipment. It addresses the problem in existing construction material racks where adjacent racks are typically bolted together to ensure stability during transport. However, when workers use forklifts to move or disassemble the stacked racks, several bolts need to be removed, resulting in a time-consuming and labor-intensive installation or disassembly process. This includes racks arranged side-by-side along the height direction... The upper support frame has several support columns fixedly connected to it, arranged in a rectangular array. This utility model allows two support frames to be stacked easily by means of the support legs at the bottom of the support frame and the support columns at the top of the adjacent lower support frame. The locking blocks on the handle slide into the corresponding slots, and the two guide blocks on the slide plate drive the two limiting plates to move closer to each other, thereby conveniently separating the two positioning rods from the positioning holes inside the support columns. This allows the two support frames to be released from their fixed position, making it easier for workers to move the upper support frame with a forklift.

[0004] However, the above patent still has shortcomings: although the patent makes it convenient to stack two support frames, the height of the material rack inside is not adjustable. Due to the different sizes of the materials stacked inside the material rack, the material rack cannot be filled completely, thus wasting a lot of space inside the material rack and making it impractical.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A construction material rack includes: a base plate 1; first side plates 2 are fixedly connected to both sides of the top of the base plate 1, a partition 3 is provided between the two first side plates 2, the partition 3 is fixedly connected to the first side plates 2 and the base plate 1, a top plate 4 is provided on the top of the base plate 1, and second side plates 5 are fixedly connected to both sides of the bottom of the top plate 4; a lifting mechanism 6 is provided between the base plate 1 and the top plate 4 to adjust the internal height of the material rack according to the volume of the material; and a latching mechanism 7 is provided at each of the four bottom corners of the base plate 1 to improve the stacking stability of the material rack. The user can adjust the distance between the base plate 1 and the top plate 4 according to the volume of the material to be stacked by means of the lifting mechanism 6. When multiple material racks are stacked, the latching mechanism 7 can be used to lock the stacked material racks together.

[0027] like Figure 3 As shown, the lifting mechanism 6 includes: two first linkage rods 8 arranged between the base plate 1 and the top plate 4; the middle of each first linkage rod 8 is rotatably connected to a second linkage rod 10 via a first rotating shaft 9; one side of each of the first linkage rods 8 and the second linkage rod 10 is rotatably connected to a fixed block 12 via a second rotating shaft 11; the fixed block 12 is fixedly connected to the top plate 4 and the base plate 1 respectively; and the ends of each of the first linkage rods 8 and the second linkage rod 10 away from the fixed block 12 are rotatably connected to a moving block via a third rotating shaft 13. 14, wherein two of the movable blocks 14 are slidably connected to slide rods 15 inside, and the other two movable blocks 14 are threadedly connected to screws 16 inside. One end of the slide rod 15 is fixedly connected to the first side plate 2, and the other end of the slide rod 15 is fixedly connected to a connecting block 17, which is fixedly connected to the base plate 1. One end of each of the two screws 16 is rotatably connected to the second side plate 5, and the other end of each of the two screws 16 passes through the second side plate 5 and extends to the outside of the second side plate 5; the screws 16 are located on the outside of the second side plate 5. One end of each is fixedly connected to a first bevel gear 18. Two second bevel gears 19 are meshed on adjacent sides of the two first bevel gears 18. A dual-axis motor 20 is set between the two second bevel gears 19. The second bevel gears 19 are respectively fixed to the outer surface of the output ends on both sides of the dual-axis motor 20. The dual-axis motor 20 is fixedly connected to the second side plate 5. The user can start the dual-axis motor 20 according to the volume of the material. The output end of the dual-axis motor 20 drives the second bevel gears 19. The second bevel gears 19 drive the first bevel gears 18. The first bevel gears 18 drive the screw 16 to rotate, which drives the two moving blocks 14 above. While the two moving blocks 14 move, they drive the top end of the first linkage rod 8 through the second rotating shaft 11. This causes the first linkage rod 8 to rotate around the first rotating shaft 9, and the second linkage rod 10 to rotate around the first rotating shaft 9. The first linkage rod 8 and the second linkage rod 10 push the top plate 4 to rise through the cooperation of the fixed block 12, the moving block 14 and the slide rod 15, thereby adjusting the height between the top plate 4 and the bottom plate 1.

[0028] like Figure 4 As shown, a conveyor belt 21 is arranged between two partitions 3. Both sides of the conveyor belt 21 are equipped with matching conveyor rollers 22. The conveyor rollers 22 are fixedly connected to the inside of each conveyor roller 22. The two ends of the conveyor rollers 23 are rotatably connected to the partitions 3 respectively. A motor 24 is fixedly connected to one partition 3 near the drive shaft 23. The output end of the drive shaft 23 is fixedly connected to the output end of the motor 24. When the motor 24 is started, the output end of the motor 24 drives the drive shaft 23, which in turn drives the conveyor belt 21. The conveyor belt 21 operates through the cooperation of the other side drive seat and the conveyor rollers 22, thereby automatically pushing out the materials piled inside the material rack, achieving the function of automatic material unloading.

[0029] like Figure 5As shown, the latching mechanism 7 includes: support feet 25 fixedly connected to the four bottom corners of the base plate 1, rectangular grooves 26 formed inside the support feet 25, a rotating plate 27 provided on one side of each support foot 25, a fourth rotating shaft 28 fixedly connected inside each rotating plate 27, both ends of the fourth rotating shaft 28 being rotatably connected to the support feet 25, and latches 29 fixedly connected to the bottom side of each rotating plate 27; and insertion blocks 30 fixedly connected to the four top corners of the top plate 4, each insertion block 30 being adapted to the rectangular grooves 26, and a latching groove 31 formed on the side of the insertion block 30 near the latches 29, the latching groove 31 being adapted to the latches 29. When stacking material racks, the user places the support leg 25 at the bottom of the upper material rack onto the outside of the insertion block 30 on the lower material rack. As the upper material rack moves the support leg 25 toward the insertion block 30, the insertion block 30 pushes the buckle 29 through the inclined surface of the buckle 29. The buckle 29 pushes the rotating plate 27, causing the rotating plate 27 to rotate around the fourth rotating shaft 28. When the insertion block 30 is fully inserted into the support leg 25, the rotating plate 27 resets. The rotating plate 27 then drives the buckle 29 to enter the slot 31 on the insertion block 30, thus completing the stacking of multiple material racks.

[0030] like Figure 5 As shown, springs 32 are provided on the side of the rotating plate 27 away from the buckle 29, and limit grooves 33 are provided on the support feet 25 near the springs 32. The springs 32 are respectively located inside the limit grooves 33, which can push the rotating plate 27 to reset.

[0031] like Figure 2 As shown, a control box 34 is fixedly connected inside the top plate 4. The control box 34 contains a battery 35, which can provide power to the device and can also be connected to a power source via wires.

[0032] like Figure 1 and Figure 2 As shown, the top hinge of the control box 34 is connected to the box door 36, and a handle 37 is fixedly connected to one side of the top of the box door 36, which can protect the battery 35.

[0033] Working principle: The user can start the dual-axis motor 20 according to the volume of the material. The output end of the dual-axis motor 20 drives the second bevel gear 19, which in turn drives the first bevel gear 18. The first bevel gear 18 drives the screw 16 to rotate, which in turn drives the two moving blocks 14 above. As the two moving blocks 14 move, they drive the top of the first linkage rod 8 through the third rotating shaft 13. This causes the first linkage rod 8 to rotate around the first rotating shaft 9, and at the same time, the second linkage rod 10 also rotates around the first rotating shaft 9. The first linkage rod 8 and the second linkage rod 10 are connected by a fixed block 1. 2. The cooperation of the moving block 14 and the sliding rod 15 pushes the top plate 4 to rise, thereby adjusting the height between the top plate 4 and the bottom plate 1. The height of the internal space of the material rack can be adjusted according to the size of the material to be stacked inside, avoiding the waste of internal space of the material rack. This solves the problem that although the existing construction material racks are convenient for stacking two support frames, the internal height of the material rack is not adjustable. Due to the different sizes of the materials stacked inside the material rack, the material rack is not fully filled, thus wasting a lot of internal space and having poor practicality.

[0034] When stacking material racks, the user places the support leg 25 at the bottom of the upper material rack onto the outside of the insertion block 30 on the lower material rack. As the upper material rack moves the support leg 25 toward the insertion block 30, the insertion block 30 pushes the buckle 29 through the inclined surface of the buckle 29. The buckle 29 pushes the rotating plate 27, causing the rotating plate 27 to rotate around the fourth pivot 28. When the insertion block 30 is fully inserted into the support leg 25, the rotating plate 27 resets. The rotating plate 27 then moves the buckle 29 into the slot 31 on the insertion block 30, thus completing the stacking of multiple material racks. Users can quickly stack material racks, and the stacked material racks can automatically lock together, improving the stability of the stacked material racks and preventing tipping.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
