Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Embodiment 1

[0039] Please refer to Figure 1-4 , the present invention provides a technical solution: a steel bar hoisting device that can store materials for a construction site, including a storage bin 2. The bottom surface of the storage bin 2 is in a state where the sides are high and the middle is low. Baffles 1 are fixedly connected to the front and rear ends of the storage bin 2. A plurality of rollers 3 are rotatably connected to the bottom surface of the storage bin 2. An opening 4 that can be opened and closed is provided on the baffle 1, and the opening 4 corresponds to the roller 3.

[0040] A plurality of partitions 5 are fixedly connected to the side of the baffle 1 facing the inside of the storage bin 2. Feed chutes 6 are formed between different partitions 5. The height of the partition 5 on the side of the baffle 1 is lower than the height of the partition 5 in the middle of the baffle 1. The distances from the bottoms of different partitions 5 to the bottom of the storage bin 2 are equal;

[0041] The width of the feed chute 6 is greater than the diameter of the steel bar.

[0042] There are two sets of storage bins 2 and baffles 1 respectively. Drive rods 7 are fixedly connected to the positions near the middle of the two sets of baffles 1. The drive rods 7 located on different baffles 1 are rotatably connected to a rotating shaft 8.

[0043] Link rods 9 are rotatably connected to the positions near the sides of the two sets of baffles 1. The link rods 9 located on different baffles 1 are rotatably connected to a connecting shaft 10.

[0044] A drive hydraulic cylinder 11 is arranged between the connecting shaft 10 and the rotating shaft 8. The two ends of the drive hydraulic cylinder 11 are respectively rotatably connected to the connecting shaft 10 and the rotating shaft 8.

[0045] The working principle and beneficial effects of the above solution:

[0046] In this application, the bottom surface of the storage bin 2 is set to be high at the sides and low in the middle. The steel bars placed have a tendency to move towards the middle under the action of gravity, avoiding the overall imbalance caused by uneven taking, solving the problem of the complex structure of the existing hoisting device's solution of changing the center of gravity of the base by adjusting the deflection angle of the roller shaft group, and also solving the problem of inconvenience in use caused by the fact that when the roller shaft group deflects to the maximum stroke, the base is still not balanced and additional counterweights need to be added to the connecting rod to achieve balance.

[0047] When a small amount needs to be taken, it is taken through the opening 4. When a large quantity needs to be taken, the drive hydraulic cylinder 11 extends, increasing the distance between the rotating shaft 8 and the connecting shaft 10, and then causing the baffles 1 to drive the storage bin 2 to rotate around the rotating shaft 8, separating the two sets of storage bins 2, and the steel bars are unloaded from between them to complete the transfer.

[0048] Among them, the partition 5 and the feed chute 6 are provided so that the steel bars maintain the same orientation after entering the storage bin 2, which is beneficial to reducing the occupation of the storage bin 2, increasing the hoisting volume, and improving the hoisting efficiency.

[0049] Embodiment 2

[0050] Please refer to Figure 5 , on the basis of Embodiment 1, a stabilizing device is arranged at the connection between the connecting shaft 10 and the drive hydraulic cylinder 11. The stabilizing device includes a fixing block 12. The fixing block 12 is rotatably connected to the connecting shaft 10. An installation plate 13 is fixedly connected to the fixing block 12. A bottom plate 24 is arranged below the installation plate 13. A stabilizing component is arranged between the installation plate 13 and the bottom plate 24. The bottom plate 24 is fixedly connected to the drive hydraulic cylinder 11.

[0051] The stabilizing assembly includes several groups of first stabilizing rods 15, second stabilizing rods 16, third stabilizing rods 17, and fourth stabilizing rods 18. The first stabilizing rods 15, second stabilizing rods 16, third stabilizing rods 17, and fourth stabilizing rods 18 form a parallelogram, and the first stabilizing rods 15, second stabilizing rods 16, third stabilizing rods 17, and fourth stabilizing rods 18 are sequentially rotatably connected. A second stabilizing shaft 20 is rotatably connected at the connection between the first stabilizing rod 15 and the third stabilizing rod 17, and a first stabilizing shaft 19 is rotatably connected at the connection between the second stabilizing rod 16 and the fourth stabilizing rod 18. A first spring 21 is arranged between the first stabilizing shaft 19 and the second stabilizing shaft 20, and both ends of the first spring 21 are respectively connected to the first stabilizing shaft 19 and the second stabilizing shaft 20.

[0052] An L-shaped first plate 14 is fixedly connected to the mounting plate 13, and the L-shaped first plate 14 is rotatably connected to the connections of the first stabilizing rod 15 and the second stabilizing rod 16;

[0053] An L-shaped second plate 23 is fixedly connected to the bottom plate 24, and the L-shaped second plate 23 is rotatably connected to the connections of the third stabilizing rod 17 and the fourth stabilizing rod 18.

[0054] A side plate 25 is fixedly connected to the mounting plate 13. A chute 26 is arranged on the side plate 25, and the side plate 25 is located outside the stabilizing assembly. A stabilizing sliding rod 22 is rotatably connected to the connection of the third stabilizing rod 17 and the fourth stabilizing rod 18, and the stabilizing sliding rod 22 is slidably connected in the chute 26.

[0055] The working principle and beneficial effects of the above solution:

[0056] A stabilizing assembly is arranged between the connecting shaft 10 and the driving hydraulic cylinder 11. When the driving hydraulic cylinder 11 contracts and drives the two groups of baffles 1 to close, after the two groups of baffles 1 are closed, the driving hydraulic cylinder 11 continues to contract, and the distance between the mounting plate 13 and the bottom plate 24 increases, and the first spring 21 is compressed, providing additional space for the contraction of the driving hydraulic cylinder 11 and avoiding damage to the driving hydraulic cylinder 11. When the driving hydraulic cylinder 11 extends and drives the two groups of baffles 1 to open, the first spring 21 returns to its original state, and the distance between the mounting plate 13 and the bottom plate 24 shortens. Then, the two groups of baffles 1 separate until they are fully opened. At this time, if the driving hydraulic cylinder 11 continues to extend, it squeezes the mounting plate 13 and the bottom plate 24, and the distance between the mounting plate 13 and the bottom plate 24 continues to shorten, and the first spring 21 is stretched;

[0057] By arranging the stabilizing assembly to provide additional driving space for the two extreme states of the two groups of baffles 1, it is beneficial to the stable operation of the hoisting device, and effectively avoids the occurrence of the top form phenomenon of the two groups of baffles 1 caused by inaccurate debugging of the telescopic amount change of the driving hydraulic cylinder 11, and simplifies the debugging of the telescopic amount of the driving hydraulic cylinder 11.

An installation plate 28 is fixedly connected to the top fixing plate 27. A drive motor 29 is fixedly connected to the installation plate 28. The output end of the drive motor 29 is fixedly connected to a drive gear 30;

[0062] Two groups of rotating frames 31 are symmetrically and rotatably connected to the installation plate 28. Two groups of half gears 32 are arranged on the two groups of rotating frames 31. The two groups of half gears 32 mesh with each other, and one of the groups of half gears 32 meshes with the drive gear 30.

[0063] The rotating frame 31 is rotatably connected to the middle position of the fixed claw arm 37. One end of the fixed claw arm 37 is fixedly connected to a second pull rod 36.

The fixed claws 40 slide along the inner wall of the storage bin 2 to hold the steel bars in the storage bin 2 tightly, completing the fixation of the steel bars;

[0070] Among them, the setting of the second spring 35 can ensure the fitting degree of the fixed claw 40 when sliding along the inner wall of the storage bin 2 as much as possible, avoiding missing the steel bars on the side;

[0071] Among them, the provision of the abutting block 38 and the stabilizing plate 39 ensures that the fixed claw arm 37 is in a rigid connection state at the extreme position, effectively ensuring the tightness of the steel bar fixation.
