DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4 As shown, the utility model provides a building steel structure stacking rack, including a bottom bracket 1, the upper surface of the bottom bracket 1 is fixedly installed with symmetrically distributed support columns 29, the outer surface of the bottom bracket 1 is rotatably installed with a rotating column 2, the bottom of the rotating column 2 is fixedly connected with a rotating shaft 21, the rotating shaft 21 is rotatably connected to the bottom bracket 1, the top of the rotating column 2 and the top of the supporting column 29 are both slidably clamped with a lifting frame 22, the outer surface of the rotating column 2 and the outer surface of the supporting column 29 are both fixedly installed with a gear box 28, and the lifting frame 22 is close to the gear. A rack 23 is fixedly installed on one side of the wheel box 28, and a transmission shaft 26 is rotatably connected to the inner wall of the gear box 28. A worm wheel 25 is fixedly connected to the outer surface of the transmission shaft 26. A transmission gear 24 is fixedly connected to the side of the transmission shaft 26 close to the worm wheel 25. The transmission gear 24 and the rack 23 are meshed with each other. A worm 27 is meshed with the outer surface of the worm wheel 25. The worm 27 is connected to the gear box 28 through the bottom surface. Rollers 11 are fixedly installed at the four corners of the lower surface of the bottom bracket 1, and a braking mechanism is fixedly installed on one side of the bottom end of the bottom bracket 1.

[0018] The brake mechanism includes symmetrically distributed pillars 3, which are fixedly installed on one side of the bottom end of the bottom bracket 1. Stud screws 33 are rotatably provided on the tops of the two pillars 3. A symmetrically distributed movable ring 34 is threadedly installed on the outer surface of the stud screws 33. The outer surface of the movable ring 34 is rotatably connected with a first transmission rod 35 and a second transmission rod 36 respectively. The second transmission rod 36 and the bottom of the first transmission rod 35 are movably clamped with a buckle column 37. Both ends of the buckle column 37 are fixedly connected with a fixed block 38. The lower surface of the fixed block 38 is fixedly connected with a brake plate 4. A clamping block 39 is fixedly installed on the outer surface of the pillar 3. The brake plate 4 is slidably clamped on the clamping block 39. Through the rotation of the stud screws 33, the movable ring 34 moves toward each other, thereby driving the first transmission rod 35 and the second transmission rod 36 to move up and down. The first transmission rod 35 and the second transmission rod 36 are connected to the brake plate 4 through the buckle column 37, and under the restriction of the clamping block 39, the brake plate 4 moves vertically, finally ensuring that the stacking rack can be stably parked after moving to a suitable position.

[0019] A fixing plate 31 is fixedly installed in the middle of one of the pillars 3, and a motor 32 is fixedly installed on the upper surface of the fixing plate 31. The driving end of the motor 32 and one end of the double-headed screw 33 are fixedly installed. After starting the motor 32, the driving end of the motor 32 will drive the double-headed screw 33 to start rotating, providing the brake plate 4 with the power source required for vertical movement, which not only improves the convenience of operation, but also ensures the stability and safety of the stacking rack.

[0020] A baffle 12 is fixedly connected to one side of the bottom bracket 1 close to the rotating column 2. The baffle 12 contacts the rotating column 2. The setting of the baffle 12 limits the rotation range of the rotating column 2 and effectively prevents the rotating column 2 from colliding during the rotation process.

[0021] A clamping rod 13 is threadedly installed on one side of the bottom bracket 1 close to the rotating shaft 21, and the clamping rod 13 is in contact with the outer surface of the rotating column 2. By removing the clamping rod 13 from the bottom bracket 1, the staff can rotate the rotating column 2, thereby changing the internal space structure of the stacking rack. When the stacking operation is completed, the rotating shaft 21 can be rotated to reset it and limited by the clamping rod 13 to ensure that the rotating column 2 remains stable during subsequent use and avoid injury or damage caused by accidental rotation.

[0022] A handle 271 is fixedly connected to one side of the double-headed screw 33 close to the gear box 28. The staff can realize the vertical movement of the lifting frame 22 by turning the handle 271, which greatly facilitates the operation of the staff.

[0023] The bottom end of the clamping block 39 is fixedly mounted with an anti-skid pad 411. By installing the anti-skid pad 411, the braking effect of the brake plate 4 can be further improved when the brake mechanism brakes the stacking rack, thereby ensuring the stability of the stacking rack.

[0024] A fixing rod 14 is fixedly installed on one side of the bottom bracket 1 close to the rotating column 2. By installing the fixing rod 14 below the rotating column 2, the overall structure of the stacking rack is made more stable and safe.

[0025] Working principle: First, when stacking steel structures, the staff controls the worm 27 to rotate by rotating the handle 271, thereby driving the worm wheel 25. Since the worm wheel 25 is connected to the transmission gear 24 through the transmission shaft 26, the transmission gear 24 starts to rotate under the action of the transmission shaft 26, thereby driving the rack 23 meshing therewith to move up and down. Since the rack 23 is fixed on the lifting frame 22, the vertical movement of the lifting frame 22 is realized, so that the stacking rack can stack more steel structures of the same type, and the self-locking structure of the worm wheel 25 and the worm 27 is used to ensure the safety and stability of the operation of the lifting frame 22.

[0026] When different types of steel structures need to be stacked, the staff first lowers the lifting frame 22 to the lowest position, that is, retracts it into the rotating column 2, then takes the clamping rod 13 out of the bottom bracket 1, and then rotates the rotating shaft 21 by operating the crane, so that the rotating column 2 and the lifting frame 22 rotate to the bottom bracket 1, thereby changing the internal structural space of the stacking rack, and according to the size of different types of steel structures, the staff can decide to rotate one or more rotating columns 2 to adjust the internal structure of the stacking rack;

[0027] In addition, the staff can move the stacking rack to the desired position via the roller 11, and then start the motor 32. The driving end of the motor 32 will drive the double-headed screw 33 to rotate, and the movable ring 34 installed on the double-headed screw 33 will therefore start to move toward each other, thereby causing the first transmission rod 35 and the second transmission rod 36 to move up and down. Since the brake plate 4 is fixedly connected to the fixed block 38, and the fixed block 38 is connected to the first transmission rod 35 and the second transmission rod 36 through the snap column 37, when the double-headed screw 33 rotates, the brake plate 4 moves vertically under the restriction of the block 39, so that the brake block 4 can move downward to fix the position of the stacking rack, and the presence of the anti-slip pad 411 further improves the braking effect of the brake plate, ensuring the stability and safety of the stacking rack.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
