Description

Technical Field

[0001] The utility model relates to the field of prefabricated building material lifting, in particular to a prefabricated building construction lifting device. Background Art

[0002] Prefabricated construction is a construction method that allows buildings to be built quickly by prefabricating building components in a factory and then transporting them to the construction site for assembly. This construction method has many advantages and is gradually gaining favor with more and more construction industries and developers. Prefabricated construction is widely used in various building types, including residential, schools, hospitals, commercial buildings, and industrial facilities. With the development of construction technology and changes in consumer demand, the use of prefabricated buildings is increasing, especially in situations where rapid construction and efficient management are required.

[0003] Prefabricated buildings have the following characteristics and advantages:

[0004] 1. Component prefabrication: Main components such as wall panels, floor slabs, roofs, columns, etc. are manufactured in specialized factories to ensure quality and precision;

[0005] 2. On-site assembly: After the prefabricated components are transported to the construction site, they are quickly assembled, which can significantly shorten the construction period;

[0006] 3. Standardized design: Prefabricated buildings usually follow standardized design and production processes to facilitate large-scale production;

[0007] 4. Modularity: Many prefabricated buildings adopt modular design, so that buildings of the same type can be flexibly combined and adjusted according to needs.

[0008] 5. High construction efficiency: Since the components are produced in the factory and assembled quickly on site, the overall construction period is greatly shortened; the factory environment can better control the production process and reduce quality problems caused by weather and other environmental factors; the labor cost can be reduced by reducing the labor required for on-site construction;

[0009] 6. Environmental protection: The production process of prefabricated buildings is more efficient, reducing the generation of construction waste. At the same time, centralized production in factories also helps to better manage resources. In the production and transportation process, materials can be used more efficiently, reducing energy consumption and waste generation;

[0010] 7. Flexibility and sustainability: Prefabricated buildings can be expanded or reconfigured as needed to adapt to changing needs.

[0011] Prefabricated buildings are becoming an important trend in the modern construction industry due to their advantages such as high construction efficiency, good quality control, energy saving and environmental protection. In the future, with the further development of technology and changes in market demand, prefabricated buildings may become more common.

[0012] However, as prefabricated buildings are assembled from various prefabricated components, how to lift and transport these prefabricated building components to the construction floor is an urgent issue to consider during construction. Although there are "vertical transport tractors" now, this type of equipment still has problems: during lifting and transportation, the lifting frame is not stable or cannot be lifted smoothly due to long-term use.

[0038] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0039] Example 1

[0040] like Figures 1 to 4 As shown, a lifting device for prefabricated building construction is used to lift prefabricated materials (components). The lifting device has undergone a series of design improvements on the original structure. The lifting device includes a lifting outer frame 1 for installation and fixation with the outer wall facade or transportation shaft of the prefabricated building. The lifting outer frame 1 is connected to movable guide rail beams 11 arranged in parallel on both sides of one end away from the prefabricated building. The two movable guide rail beams 11 are connected to a lifting movable frame 2 for installing and connecting a cargo box in a movably movable manner. The upper and lower ends of both sides of the lifting movable frame 2 are respectively connected to movable limit structures for movable limit settings with the movable guide rail beams 11. The top of the lifting outer frame 1 is connected to a lifting device for driving the lifting movable frame to move up and down along the two movable guide rail beams. The assembled cargo box to be placed is installed and fixed on the lifting movable frame 2, and the assembled materials or components to be lifted and transported are placed in the cargo box; the assembled materials or components in the cargo box on the lifting movable frame 2 are lifted by controlling the lifting device; and, during the lifting process, the lifting movable frame 2 is stably guided and limited by the added movable limiting structure, ensuring that the lifting movable frame 2 and the assembled materials or components in the cargo box on the lifting movable frame 2 can be stably and reliably lifted and moved to the designated floor position of the assembled building.

[0041] Example 2

[0042] On the basis of Example 1, the additional and improved movable limiting structure includes an outer limiting roller 21 and an inner limiting roller 22; the outer limiting roller 21 is rotatably connected to the lifting movable frame 2 through a connecting seat, and the outer limiting roller 21 is in rolling and limiting contact with the surface of one end of the movable guide rail beam 11 close to the lifting outer frame 1; the inner limiting roller 22 is rotatably connected to the lifting movable frame 2 through a connecting seat, and the inner limiting roller 22 and the outer limiting roller 21 can be arranged to roll relative to each other; and, the movable guide rail beam 11 is provided with a limiting slide groove, and the inner limiting roller 22 is placed in the limiting slide groove and is slidably adapted to the limiting slide groove.

[0043] In the embodiment, a movable limiting structure is provided at both upper and lower ends of both sides of the lifting movable frame 2, and the inner limiting roller 22 of the movable limiting structure is provided in the limiting slide groove provided in the movable guide rail beam 11, so that the outer limiting roller 21 is in rolling contact with the surface of the lifting outer frame 1 close to the end of the lifting movable frame 2; this is equivalent to rolling limiting the inner limiting roller 22 and the outer limiting roller 21 on the movable guide rail beam 11; while ensuring the mobility, relative limiting can also be achieved, thereby ensuring that the lifting movable frame 2 and the cargo box (including prefabricated materials or components) on the lifting movable frame 2 can be stably lifted along the lifting outer frame 1 under the lifting action of the lifting device, thereby lifting and moving the prefabricated materials or components in the cargo box to the designated prefabricated building floor position.

[0044] In addition, a pair of clamping rollers 23 that can roll relative to each other are connected to the upper and lower ends of one end surface of the lifting movable frame 2 close to the lifting outer frame 1; a guide rail 12 is arranged between the two clamping rollers 23, and the two clamping rollers are in rolling and limiting contact with the guide rail 12; the guide rail 12 is fixedly connected to the lifting outer frame 1. By connecting a pair of clamping rollers 23 that can roll relative to each other to the upper and lower ends of one end surface of the lifting outer frame 1 close to the lifting outer frame 1, the two pairs of clamping rollers 23 are rolled and limited with the guide rail 12 that passes vertically through the middle, thereby further ensuring that during the lifting process, the cargo boxes (including assembled materials or components) on the lifting movable frame 2 and the lifting movable frame 2 can be stably lifted along the lifting outer frame 1.

[0045] Example 3

[0046] Further, in the embodiment, the lifting device mentioned in the lifting device includes a vertical transport tractor 3 (existing technology); the vertical transport tractor 3 is used to be installed and fixed on the top of the lifting outer frame 1, and the vertical transport tractor 3 is connected to the lifting movable frame 2 through a vertical conveyor belt. At the same time, a counterweight 4 is also provided on the lifting outer frame 1; the counterweight 4 is connected and arranged to be lifted and lowered with the vertical transport tractor 3 through a vertical conveyor belt, and is used to balance and stabilize the weight on the lifting movable frame 2 (including the lifting movable frame 2, the cargo box installed on the lifting movable frame 2, and the total weight of the assembled materials or components in the cargo box). In the implementation process, in order to further achieve the stable up and down movement of the counterweight 4, the connecting frame used to connect the counterweight 4 is also installed with a movable limit structure that is the same as the lifting movable frame 2 and is symmetrically arranged on both sides, that is, it includes the so-called outer limit roller 21 and the inner limit roller 22, and the outer limit roller 21 and the inner limit roller 22 are also arranged to be movable (rolling) limited with the movable guide rail beam 11 of the lifting outer frame 1, so as to achieve the purpose.

[0047] In addition, an operation control platform 5 for operators to operate is installed at the top of the lifting outer frame 1, and protective railings are installed around the operation control platform 5; a ladder 51 for operators to go up and down is connected to the operation control platform 5.
