Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a turnover hoisting mechanism and a turnover hoisting method. Background Art

[0002] Due to the heavy weight and large volume of the integrated modular house, each modular house is customized according to the house, such as opening doors and windows on a certain side wall, and the weight of the modular house is uneven. During the production or assembly process of the modular house, each modular house needs to be turned to the appropriate angle by a turning machine, and then hoisted to the required position by a hoisting frame.

[0003] Large integrated modular houses and prefabricated concrete components require a lot of hoisting and turning actions during the production process. However, the existing turning equipment and hoisting equipment are two independent devices with high investment costs and low operating efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is how to solve the problem of overturning and hoisting in the production or assembly process of large integrated module houses or prefabricated components.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a flip hoisting mechanism, including a hoisting frame, a hoisting assembly and a flip assembly, the hoisting assembly is fixedly connected or detachably connected to the hoisting frame, and the flip assembly is fixedly connected to the hoisting frame.

[0006] The beneficial effects of the present invention are as follows: the flipping and hoisting mechanism has two functions of flipping and hoisting, which improves the work efficiency of hoisting, transportation and flipping operations of integrated modular houses and large building components, saves investment in production equipment, and the equipment is light, easy to move, low in cost, and does not occupy a fixed site.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the flip assembly includes a rotating roller and at least one flexible sling, the rotating roller is rotatably mounted on the hanging frame, the flexible sling is an annular belt, the flexible sling is sleeved on the outside of the rotating roller, and is used to be sleeved on the outside of the prefabricated component.

[0009] The beneficial effect of adopting the above further scheme is that the driving mechanism drives the rotating roller to rotate, and the rotating roller drives the flexible sling to move along its length direction through friction, thereby driving the prefabricated components in the flexible sling to flip. The flipping assembly has a simple and light structure, low manufacturing cost, does not occupy a fixed site, and is easy to move. Multiple flexible slings can be set along the length direction of the rotating roller to increase the load-bearing capacity and reliability.

[0010] Furthermore, the outer surface of the rotating roller has an anti-slip layer.

[0011] The beneficial effect of adopting the above further solution is: an anti-skid layer is provided on the outer surface of the rotating roller to increase the friction between the rotating roller and the flexible sling, thereby increasing the structural reliability and improving the turnover efficiency.

[0012] Furthermore, both ends of the rotating roller are rotatably connected to the hanging frame through bearings.

[0013] The beneficial effect of adopting the above further solution is that the rotating roller is installed through the bearing, and the resistance during the rotation process is small.

[0014] Furthermore, the flipping and hoisting mechanism also includes a driving mechanism, which is fixedly connected to the hoisting frame, and is drivingly connected to the rotating roller, and the driving mechanism is a reduction motor.

[0015] Furthermore, the flip assembly is arranged in the middle of the hanging frame and along the length direction of the hanging frame.

[0016] The beneficial effect of adopting the above further solution is that the hanging frame and the structure installed thereon are symmetrical and the forces are balanced.

[0017] Furthermore, there are multiple flip assemblies, and the multiple flip assemblies are coaxially arranged at intervals.

[0018] The beneficial effect of adopting the above further solution is that multiple flip assemblies are provided, which can be used to flip components with a longer length, and can also reduce the length of a single flip assembly and increase the structural strength of the flip assembly.

[0019] Furthermore, the hanging assembly includes multiple linear components and multiple hanging connectors, the multiple linear components are symmetrically arranged on the hanging frame, the hanging frame is provided with multiple hanging holes spaced apart along the circumferential direction, the multiple hanging connectors are spaced apart along the circumferential direction of the hanging frame, and are used to be detachably connected to prefabricated components, the two ends of each linear component are fixedly connected to the hanging frame or the hanging connector, and the middle part of the linear member alternately passes through the hanging connector and the hanging hole.

[0020] The beneficial effect of adopting the above further scheme is that the multiple lifting connectors on each linear component are used to connect with the prefabricated components. During lifting, each linear component can slide in the lifting hole and adjust to the force balance position, so that all the lifting connectors on the linear component are subjected to the same force, reducing the damage to the prefabricated components or deformation of the prefabricated components caused by the concentrated force on a certain lifting connector. Multiple linear components are symmetrically arranged on the lifting frame and are relatively independent and do not affect each other, so the prefabricated components are subjected to uniform force. When lifting large modular houses or components, the objects being lifted will not tilt due to different weights in the front and back or left and right, affecting the installation. The deformation of large modular houses or components is reduced, and high-quality lifting is achieved.

[0021] Furthermore, the flipping lifting mechanism also includes a top lifting buckle and multiple lifting chains, one end of each of the lifting chains is fixedly connected to the top lifting buckle, the other ends of the multiple lifting chains are arranged at intervals along the circumference of the lifting frame and fixedly connected to the lifting frame, and the other ends of the multiple lifting chains are symmetrically arranged on the lifting frame.

[0022] The beneficial effect of adopting the above further scheme is: the crane or lifting equipment uses a hook to lift the top lifting buckle, and the top lifting buckle lifts the lifting frame through multiple lifting chains. The multiple lifting chains are symmetrically arranged, and the lifting frame is balanced in force.

[0023] The invention also provides a turnover and hoisting method, which uses the turnover and hoisting mechanism to turnover and hoist prefabricated components.

[0024] The beneficial effects are: the flipping and lifting mechanism is used to realize the two functions of flipping and lifting, which improves the work efficiency of lifting, transportation and flipping operations of integrated modular rooms and large building components, saves investment in production equipment, and the equipment is light, easy to move, low in cost, and does not occupy a fixed site.

[0029] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] Embodiment 1

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a flip hoisting mechanism, including a hoisting frame 4, a hoisting component and a flip component, the hoisting component is fixedly connected or detachably connected to the hoisting frame 4, and the flip component is fixedly connected to the hoisting frame 4.

[0032] The flipping and hoisting mechanism of this embodiment has two functions, flipping and hoisting, and can be used to hoist prefabricated components, especially suitable for integrated modular houses and large-scale building components. It improves the work efficiency of hoisting, transportation and flipping operations of integrated modular houses and large-scale building components, saves investment in production equipment, and the equipment is light, easy to move, low in cost, and does not occupy a fixed site.

[0033] Specifically, Figure 1 and Figure 2 As shown, the hanging frame 4 of this embodiment is a frame structure formed by splicing I-beams. The hanging frame 4 has a simple structure, saves materials, and is light in weight.

[0034] In addition, in the prior art, for the flipping of large components, a fixed 90-degree flipping machine is mostly used. Such a flipping machine is designed with a corresponding size according to the size of the component to be flipped. For example, if an integrated modular house weighing tens of tons is to be flipped, the flipping machine will be designed to be very large in size. The fixed flipping mechanism occupies a large area, has a relatively high investment cost, is inconvenient to use, and is difficult to be applied to the hoisting frame 4.

[0035] On the basis of the above technical solution, the flipping assembly of this embodiment includes a rotating roller 5 and at least one flexible sling 9, the rotating roller 5 is rotatably installed on the lifting frame 4, the flexible sling 9 is an annular belt, and the flexible sling 9 is sleeved on the outside of the rotating roller 5 and is used to be sleeved on the outside of the prefabricated component 1.

[0036] like Figure 1 As shown, the flexible sling 9 is sleeved on the outer side of the rotating roller 5 and the prefabricated component 1. The flexible sling 9 is manually pulled to drive the rotating roller 5 to rotate. The rotating roller 5 drives the flexible sling 9 to move along its length direction through friction, thereby driving the prefabricated component 1 in the flexible sling 9 to flip. The flip assembly of this embodiment has a simple and light structure, low manufacturing cost, does not occupy a fixed site, and is easy to move. Multiple flexible slings 9 can be set along the length direction of the rotating roller 5 to increase the load-bearing capacity and reliability.

[0037] Optionally, according to the length and weight of the prefabricated component 1 to be hoisted, one or more flexible slings 9 can be evenly arranged along the length direction of the rotating roller 5. The flexible sling 9 is a circular flat belt with a certain width or a single sling with both ends fixedly connected. When the flexible sling 9 is used to flip the prefabricated component or the integrated module house, it is not suitable to cause damage to the surface of the component. If a chain or iron chain is used to lift the heavy object to flip the component, in order not to damage the surface of the hoisted component, it is necessary to replace the contact section with the component with a flexible sling type belt, or wrap the surface of the chain or iron chain with very thick cotton cloth or other soft materials. This increases safety hazards and costs. In addition, since the hoisting chain needs to be hung on a gear or sprocket when flipping, when the number of chains or iron chains is increased to meet the flipping requirements of the flipped component, the gears or sprockets on the corresponding shaft must be increased, which requires a very large investment and cannot be achieved on site. Therefore, compared with chains or iron chains, the flexible slings 9 of this solution will not cause damage to the prefabricated component 1. At the same time, the number of flexible slings 9 can be increased or decreased as needed on site, which is convenient to use.

[0038] Based on any of the above solutions, the outer surface of the rotating roller 5 has an anti-slip layer.

[0039] An anti-skid layer is provided on the outer surface of the rotating roller 5 to increase the friction between the rotating roller 5 and the flexible sling 9, thereby increasing the structural reliability and improving the turnover efficiency.

[0040] Optionally, the surface of the flexible sling 9 in contact with the rotating roller 5 may also be provided with an anti-slip layer.

[0041] Specifically, the anti-skid layer is made of rubber or other anti-skid materials, or the surface of the rotating roller 5 or the flexible sling 9 is embossed, roughened or the like.

[0042] On the basis of any of the above solutions, both ends of the rotating roller 5 are rotatably connected to the hanging frame 4 through bearings.

[0043] The rotating roller 5 is installed by bearings, and the resistance during the rotation process is small.

[0044] On the basis of any of the above solutions, the flipping and hoisting mechanism further includes a driving mechanism 11, the driving mechanism 11 is fixedly connected to the hoisting frame 4, the driving mechanism 11 is transmission-connected to the rotating roller 5, and the driving mechanism 11 is a reduction motor.

[0045] The driving mechanism 11 drives the rotating roller 5 to rotate, saving manpower.

[0046] Specifically, the reduction motor may be a reduction motor with a rocking braking function, thereby realizing the remote-controlled automatic turning over of the prefabricated component 1 .

[0047] On the basis of any of the above solutions, the flip assembly is arranged in the middle of the hanging frame 4 and along the length direction of the hanging frame 4.

[0048] The hanging frame 4 and the structure installed thereon are symmetrical and balanced in force.

[0049] In one specific example, Figure 1 As shown, the hanging frame 4 is a rectangular frame, and the flip assembly is arranged on the wide side symmetry axis of the hanging frame 4. Of course, in other examples, the hanging frame 4 can also be other polygonal or circular frames.

[0050] Based on any of the above solutions, there are multiple flip assemblies, and the multiple flip assemblies are coaxially arranged at intervals.

[0051] Providing multiple flipping assemblies can be used to flip components with a longer length, and can also reduce the length of a single flipping assembly and increase the structural strength of the flipping assembly.

[0052] In one specific example, Figure 1 As shown, there are two flipping assemblies, and the two flipping assemblies are symmetrically arranged relative to the long side symmetry axis.

[0053] In addition, when hoisting prefabricated modular houses, the existing solution usually adopts the method of increasing the hoisting points to improve the hoisting safety, reduce the hoisting deformation of the modular house, and the concentrated stress damage caused by the hoisting. This hoisting method faces two problems:

[0054] 1. If each lifting point is directly connected to the crane hook, it is difficult to keep the stress of each lifting point consistent when lifting the integrated module. The stress is easily concentrated on one or several lifting points, resulting in concentrated stress damage to a single lifting point, while other lifting points are not stressed or are less stressed, and finally each lifting point is damaged in turn, resulting in lifting failure.

[0055] 2. If each lifting point and the hanger are connected by a pulley with a steel wire rope, that is, the lifting frame installs multiple fixed pulleys in the circumference, and sets multiple movable pulleys on the module house, and a steel wire rope alternately passes through the movable pulley and the fixed pulley to lift the module house. In this way, it seems that the weight will be evenly transmitted to each lifting point through the pulley and the steel wire rope, but because the module house has doors and windows on the single wall, there is an uneven weight on the horizontal plane of the module roof, and it is difficult to find the center of gravity when lifting. After lifting, the module house will tilt toward the heavy part, and it is difficult to be lifted horizontally to the installation position, which is not conducive to assembly; the force on each lifting point is also different, resulting in the problem of deformation and damage of the entire module house when lifting. For integrated module houses (including wooden structures, steel structures and concrete structures) with high requirements for module room connection accuracy and changes, it is difficult to reduce the deformation of the integrated module house during lifting and transportation. The existing lifting frame is difficult to meet the lifting requirements of the integrated module house.

[0056] Based on any of the above schemes, the lifting assembly of this embodiment includes multiple linear components 6 and multiple lifting connectors 8, and the multiple linear components 6 are symmetrically arranged on the lifting frame 4. The lifting frame 4 is provided with multiple lifting holes 7 spaced apart along the circumferential direction. The multiple lifting connectors 8 are arranged spaced apart along the circumferential direction of the lifting frame 4 and are used to be detachably connected to the prefabricated component 1. The two ends of each of the linear components 6 are fixedly connected to the lifting frame 4 or the lifting connector 8, and the middle part of the linear component 6 alternately passes through the lifting connector 8 and the lifting hole 7.

[0057] The multiple lifting connectors 8 on each linear member 6 are used to connect with the prefabricated member 1. During lifting, each linear member 6 can slide in the lifting hole 7 and adjust to a force-balanced position, so that all the lifting connectors 8 on the linear member 6 are subjected to the same force, thereby reducing the damage to the prefabricated member 1 or the deformation of the prefabricated member 1 caused by the concentrated force on a certain lifting connector 8. The multiple linear members 6 are symmetrically arranged on the lifting frame 4 and are relatively independent and do not affect each other, so that the prefabricated member 1 is subjected to uniform force. When lifting a large modular room or component, the object being lifted will not tilt due to the different weights of the object in the front and back or left and right, which will affect the installation. The deformation of large modular rooms or components is reduced, and high-quality lifting can be achieved.

[0058] Optionally, the number of the linear members 6 may be an odd number or an even number. In a more preferred example, the number of the linear members 6 is an even number.

[0059] Optionally, the linear member 6 is a sling, a rope, or a flexible fabric with high tensile strength.

[0060] Optionally, the hanging connector 8 is a hook or a hanging buckle. The hanging connector 8 is provided with a through hole for the linear member 6 to pass through.

[0061] The lifting assembly of this embodiment does not need to be provided with a fixed pulley and a movable pulley, and has a simple structure, light weight and low manufacturing cost.

[0062] Optionally, the hanging hole 7 is a circular hole, an elliptical hole or a hole of other shapes. In one specific example, the hanging hole 7 is a circular hole.

[0063] Specifically, Figure 2 As shown, the middle portion of the linear member 6 alternately passes through the lifting connector 8 and the lifting hole 7 to form a W-shaped structure. The plurality of lifting holes 7 through which the linear member 6 passes may be a plurality of adjacent lifting holes 7, or may be a plurality of lifting holes 7 with at least one lifting hole 7 spaced between two adjacent ones.

[0064] Based on any of the above schemes, the flipping lifting mechanism also includes a top lifting buckle 2 and multiple lifting chains 3, one end of the multiple lifting chains 3 is fixedly connected to the top lifting buckle 2, the other ends of the multiple lifting chains 3 are arranged at circumferential intervals along the lifting frame 4 and fixedly connected to the lifting frame 4, and the other ends of the multiple lifting chains 3 are symmetrically arranged on the lifting frame 4.

[0065] A crane or lifting equipment uses a hook to lift a top lifting buckle 2, and the top lifting buckle 2 lifts a lifting frame 4 through a plurality of lifting chains 3. The plurality of lifting chains 3 are symmetrically arranged, and the lifting frame 4 is balanced in force.

[0066] Specifically, the hanging frame 4 is provided with a hanger hanging part 10 corresponding to the number of the hanging chains 3, and the hanging chains 3 are connected to the corresponding hanger hanging parts 10. The hanger hanging parts 10 are annular components fixed on the hanging frame 4, or holes directly opened on the hanging frame 4.

[0067] In one specific example, the plurality of hoisting holes 7 on the hoisting frame 4 are grouped based on the hanger hoisting portion 10, and a linear member 6 is provided in each group, and the midpoint (or a position near the midpoint) of each linear member 6 is aligned with the hanger hoisting portion 10. The middle of the linear member 6 alternately passes through the hoisting connector 8, so that the upward hoisting force of the hanger hoisting portion 10 can be evenly transmitted to each hoisting connector 8, so that the prefabricated component 1 is hoisted horizontally, avoiding the prefabricated component 1 from tilting due to uneven weight distribution, and minimizing the hoisting damage or deformation of the prefabricated component 1.
