Technical Field
[0001] This utility model belongs to the technical field of box body flipping, and specifically relates to a box body flipping sling. Background Technique
[0002] In many fields such as current industrial production, warehousing logistics, and construction, the lifting and unloading operations of box bodies are frequent and crucial links. However, the existing box body lifting and unloading technologies face a series of severe challenges and problems in practical applications.
[0003] In the past, during the lifting process of box bodies, the methods used were often relatively simple and crude. Usually, only hooks or ropes were used to directly hook or tie the box bodies, and this method could not provide a stable and reliable clamping force. During the lifting process, once encountering external interferences such as wind force, sudden start-stop or unstable operation of the lifting equipment, the box body is extremely likely to shake violently. Due to the lack of effective limiting and fixing measures, the box body may fall off the lifting device and directly hit the ground.
[0004] When the box body drops, the impact force generated will not only cause serious damage to the box body itself and make it unable to be used again, increasing the cost input of the enterprise. Moreover, if the box body contains fragile, precise, or valuable items, these items will also be damaged accordingly, causing huge economic losses. More seriously, the falling of the box body may injure the on-site workers and trigger serious safety accidents.
[0005] In terms of unloading operations, traditional methods mostly rely on manual labor or complex mechanical devices. Manual unloading is not only inefficient, but also during the process of flipping the box body, due to the difficulty of accurately controlling by manpower, the situation of the box body losing balance and falling is likely to occur. And some existing mechanical unloading equipment, although improving the unloading efficiency to a certain extent, still cannot effectively avoid the accidental falling of the box body during the flipping process due to the unreasonable structure design and complex operation.
[0006] In addition, when lifting the box body, due to the lack of effective protective measures, when the box body drops, the internal materials will also scatter accordingly. This will not only cause waste and loss of materials, but for some special nature materials such as toxic, harmful, inflammable, and explosive materials, it will also pose a great threat to the environment and personnel safety.
[0007] For this reason, we propose a box body flipping sling. This device can not only easily flip the box body, realize the rapid unloading of internal materials, improve work efficiency, but also can prevent the accidental falling of materials and the box body during the lifting process by setting a protective net, ensuring the safety of the lifting process. Content of the Utility Model
[0008] The purpose of this utility model is to provide a box body turnover sling. This device can not only conveniently turnover the box body to achieve rapid discharging of internal materials and improve work efficiency, but also prevent the accidental dropping of materials and the box body during hoisting by setting a protective net, ensuring the safety of the hoisting process.
[0009] The technical solution adopted by this utility model is as follows:
[0010] A box body turnover sling includes a first support plate and a first box body. A hoisting ring connected to an external hoisting machine is arranged at the top of the first support plate. A chute is opened at the bottom of the first support plate. A rotating component is arranged inside the chute. Two clamping plates are arranged on the rotating component. A turnover component is arranged on one of the clamping plates. A first rotating shaft is arranged on the turnover component. A first cross-shaped limiting plate is installed on one side of the first rotating shaft. A second rotating shaft is arranged on the other clamping plate. A second cross-shaped limiting plate is arranged on one side of the second rotating shaft. The first box body is arranged between the second cross-shaped limiting plate and the first cross-shaped limiting plate;
[0011] Two groups of connecting blocks are arranged on both sides of the clamping plate. Each group of connecting blocks has two. A rotating roller is arranged between the two connecting blocks. A protective net is arranged between the two rotating rollers. The protective net has two sections, one is a sealing surface and the other is an opening surface. Third rotating shafts are arranged at one ends of the two rotating rollers. A conveyor belt is sleeved on the two third rotating shafts and one first rotating shaft.
[0012] Further, the rotating component includes a first motor arranged on the first support plate. The output end of the first motor is installed with a rotating rod located inside the chute. Opposite threads are opened on the rotating rod. Corresponding thread sleeves are arranged on the opposite threads. The bottoms of the two thread sleeves are respectively connected to the two clamping plates.
[0013] Further, cross-shaped limiting grooves are opened on both sides of the first box body.
[0014] Further, the turnover component includes a bracket arranged on one of the clamping plates. A reciprocating stepping motor is arranged on the bracket. The output end of the reciprocating stepping motor is connected to the first rotating shaft.
[0015] Further, the cross-sectional area of the opening surface of the protective net is smaller than the cross-sectional area of the opening of the first box body.
[0016] Further, weight-reducing holes are arranged on the clamping plate.
[0017] The technical effects achieved by this utility model are:
[0018] First, connect it to the hoisting machine through the hoisting ring, and then place the first box body between the second cross-shaped limiting plate and the first cross-shaped limiting plate (at this time, the opening of the first box body faces upward, and the protective net is the sealed end). Then, drive the two clamping plates to move relatively through the rotating assembly, so as to clamp and fix the first box body between the second cross-shaped limiting plate and the first cross-shaped limiting plate, and then carry out hoisting. After the hoisting is completed, when it is necessary to pour out the things inside the first box body, the flipping assembly is started. The flipping assembly drives the first rotating shaft to drive the first cross-shaped limiting plate to drive the first box body to drive the second cross-shaped limiting plate to drive the second rotating shaft to rotate, so as to carry out flipping. At the same time, when flipping, drive the two third rotating shafts to rotate through the conveyor belt, and the two third rotating shafts drive the two rotating rollers to rotate, so as to wind and unwind the protective net. At this time, the opening surface of the protective net is opened, so as to discharge the materials inside the first box body. This device can not only easily flip the box body, realize the rapid unloading of the internal materials, improve work efficiency, but also prevent the accidental falling of the box body and materials during hoisting by setting the protective net, ensuring the safety of the hoisting process.

[0026] To make the purpose and advantages of this utility model clearer, the following provides a specific description of this utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model and does not strictly limit the scope of protection of the specific claims of this utility model.
[0027] As Figures 1-5 shown, the technical solution adopted by this utility model is specifically as follows: A box body flipping sling, including a first support plate 1 and a first box body 2. A lifting ring 3 connected to an external hoisting machine is arranged at the top of the first support plate 1. A chute 4 is opened at the bottom of the first support plate 1. A rotating assembly is arranged inside the chute 4. Two clamping plates 5 are arranged on the rotating assembly. A flipping assembly is arranged on one of the clamping plates 5. A first rotating shaft 6 is arranged on the flipping assembly. A first cross-shaped limiting plate 7 is installed on one side of the first rotating shaft 6. A second rotating shaft 8 is arranged on the other clamping plate 5. A second cross-shaped limiting plate 9 is arranged on one side of the second rotating shaft 8. The first box body 2 is arranged between the second cross-shaped limiting plate 9 and the first cross-shaped limiting plate 7.
[0028] Two groups of connecting blocks 10 are arranged on both sides of the clamping plate 5. Each group of connecting blocks 10 has two. A rotating roller 11 is arranged between the two connecting blocks 10. A protective net 12 is arranged between the two rotating rollers 11. The protective net 12 has two sections, one section is a sealing surface and the other section is an opening surface. And third rotating shafts 13 are arranged at one ends of the two rotating rollers 11. A conveyor belt 14 is sleeved on the two third rotating shafts 13 and a first rotating shaft 6.
[0029] Its working principle is as follows: First, connect with the hoisting machine through the lifting ring 3. Then place the first box body 2 between the second cross-shaped limiting plate 9 and the first cross-shaped limiting plate 7 (at this time, the opening of the first box body 2 faces upward and the protective net 12 is the sealed end). Then drive the two clamping plates 5 to move relatively through the rotating assembly, so as to clamp and fix the first box body 2 between the second cross-shaped limiting plate 9 and the first cross-shaped limiting plate 7, and then perform hoisting. After the hoisting is completed, when the things inside the first box body 2 need to be poured out, the flipping assembly is started. The flipping assembly drives the first rotating shaft 6 to drive the first cross-shaped limiting plate 7 to drive the first box body 2 to drive the second cross-shaped limiting plate 9 to drive the second rotating shaft 8 to rotate, so as to perform flipping. At the same time, when flipping, drive the two third rotating shafts 13 to rotate through the conveyor belt 14. The two third rotating shafts 13 drive the two rotating rollers 11 to rotate, so as to make the protective net 12 perform winding and unwinding functions. At this time, the opening surface of the protective net 12 is opened, so that the materials inside the first box body 2 are discharged. This device can not only conveniently flip the box body, realize the rapid unloading of the internal materials, improve work efficiency, but also prevent the box body and materials from accidentally falling during hoisting through the setting of the protective net 12, ensuring the safety of the hoisting process.
[0030] Among them, the rotating assembly includes a first motor 15 arranged on the first support plate 1. A rotating rod 16 located inside the chute 4 is installed at the output end of the first motor 15. Opposite threads are provided on the rotating rod 16, and corresponding thread sleeves 17 are arranged on the opposite threads. The bottoms of the two thread sleeves 17 are respectively connected to the two clamping plates 5.
[0031] The first motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the two thread sleeves 17 to make the two clamping plates 5 move relatively or in the opposite direction, thereby facilitating the clamping of the first box body 2.
[0032] Cross-shaped limiting grooves 18 are provided on both sides of the first box body 2. The first cross-shaped limiting plate 7 and the second cross-shaped limiting plate 9 enter the inside of the cross-shaped limiting grooves 18 for fixation and clamping. The first cross-shaped limiting plate 7 and the second cross-shaped limiting plate 9 can enter the inside of the cross-shaped limiting grooves 18, which has a good clamping and fixing effect, and is convenient for flipping the drilling rig to drive the first box body 2 to flip.
[0033] The flipping assembly includes a bracket arranged on one of the clamping plates 5. A reciprocating stepping motor 19 is arranged on the bracket. The output end of the reciprocating stepping motor 19 is connected to the first rotating shaft 6. The reciprocating stepping motor 19 is fixed by the bracket, and the first rotating shaft 6 is driven to rotate by the reciprocating stepping motor 19.
[0034] The material of the protective net 12 can be selected as follows:
[0035] 1. High-strength steel wire mesh: It has the characteristics of high strength and wear resistance, can withstand the impact and friction of materials, is not easy to deform and damage, and ensures the reliability of long-term use.
[0036] 2. Nylon fiber mesh: It has relatively high strength and toughness, is relatively light in weight, and also has certain corrosion resistance and wear resistance.
[0037] 3. Stainless steel woven mesh: The stainless steel material has good corrosion resistance and strength, and can be used for a long time in harsh environments without rusting or damage.
[0038] The cross-sectional area of the opening surface of the protective net 12 is smaller than the cross-sectional area of the opening of the first box body 2. Such a design is to ensure that when the first box body 2 is flipped for discharging, the materials can smoothly flow out of the box body, and at the same time prevent the materials from accidentally falling during the hoisting process. Specifically, when the first box body 2 is flipped, the opening surface of the protective net 12 will open, allowing the materials in the box body to pass through. Since the cross-sectional area of the opening surface is smaller than the cross-sectional area of the opening of the box body, this helps to concentrate and guide the outflow of the materials and prevent the materials from scattering during the discharging process.
[0039] Secondly, the cross-sectional area of the opening surface of the protective net 12 is smaller than the cross-sectional area of the opening of the first box body 2. Even if the first box body 2 falls, the first box body 2 will fall on the protective net 12 and will not fall from the opening, thereby preventing the accidental fall of materials during hoisting.
[0040] Weight-reducing holes (not marked in the figure) are provided on the clamping plate 5. Through the weight-reducing holes, the weight of the entire device can be reduced, facilitating subsequent use.
[0041] The working principle of this utility model is as follows: First, connect with the hoisting machine through the hoisting ring 3, and then place the first box body 2 between the second cross-shaped limiting plate 9 and the first cross-shaped limiting plate 7 (at this time, the opening of the first box body 2 faces upward and the protective net 12 is the sealed end). Then, drive the two clamping plates 5 to move relatively through the rotating assembly, so as to clamp and fix the first box body 2 between the second cross-shaped limiting plate 9 and the first cross-shaped limiting plate 7, and then carry out hoisting. After the hoisting is completed, when the contents inside the first box body 2 need to be emptied, the flipping assembly is started. The flipping assembly drives the first rotating shaft 6 to make the first cross-shaped limiting plate 7 drive the first box body 2 and the second cross-shaped limiting plate 9 drive the second rotating shaft 8 to rotate, so as to carry out flipping. At the same time, when flipping, drive the two third rotating shafts 13 to rotate through the conveyor belt 14, and the two third rotating shafts 13 drive the two rotating rollers 11 to rotate, so as to wind and unwind the protective net 12. At this time, the opening surface of the protective net 12 is opened, so that the materials inside the first box body 2 are discharged. This device can not only easily flip the box body to achieve rapid unloading of the internal materials and improve work efficiency, but also prevent the accidental fall of the box body and materials during hoisting through the setting of the protective net 12, ensuring the safety of the hoisting process.
[0042] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model are implemented according to the conventional means in this field without special explanation and limitation.
