Description

Technical Field

[0001] The utility model relates to the field of lifting of assembled building components, in particular to an assembled building construction lifting device. Background Art

[0002] Prefabricated building components refer to building components that are prefabricated in factories during the construction process. These components are assembled and installed at the construction site through corresponding connection methods to form the overall structure of the building. The advantages of prefabricated buildings include fast construction speed, controllable quality, reduced impact of on-site construction on the environment, and reduced labor costs, and are increasingly valued by the construction industry. In modern buildings, the application of prefabricated building components is becoming more and more widespread, and it is also one of the important ways to achieve building industrialization.

[0003] As prefabricated components are prefabricated, they are transported to the construction site during construction and then assembled according to the construction sequence. Most of these prefabricated building components are made of concrete or reinforced concrete, which are relatively heavy. When the prefabricated building under construction reaches a certain height, and the amount of prefabricated building components is small, or the large tower crane cannot reach it, if manual transportation is used, the efficiency is low and it is not economical. At this time, the large tower crane cannot reach it. Therefore, the lifting device with this design improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0029] 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.

[0030] Example 1

[0031] like Figures 1 to 4 As shown, a lifting device for prefabricated building construction is a tool for lifting prefabricated building components between manual and large tower cranes, and is used to lift prefabricated building components (including prefabricated beams and slabs and bricks required for masonry). The lifting device includes a lifting pole 1, on which an adjustment structure for adjusting the balance of the lifting pole 1 is provided, and the two ends of the lifting pole 1 are slidably connected with clamping structures for clamping and limiting the hoisted prefabricated building components. The balanced lifting position is adjusted by adjusting the adjustment structure, and then the prefabricated building components to be lifted are clamped and limited by controlling the clamping structures provided at both ends of the lifting pole 1; finally, the prefabricated building components to be lifted are adjusted and controlled to be lifted to the specified floor panel position.

[0032] In the embodiment, the clamping structure includes a first clamping claw 2 and a second clamping claw 3; the upper parts of the first clamping claw 2 and the second clamping claw 3 are rotatably connected through a rotating shaft (arranged in a scissor-like hinged arrangement), and the bottom ends of the first clamping claw 2 and the second clamping claw 3 are both connected with clamping and limiting steel; at the same time, the top end of the first clamping claw 2 is hinged with a first movable connecting rod 21, and the top end of the second clamping claw 3 is hinged with a second movable connecting rod 31. The top ends of the first movable connecting rod 21 and the second movable connecting rod 31 are hinged on the sliding structure through an articulated seat, and the sliding structure and the lifting and hoisting shoulder pole 1 are slidably arranged. The assembled components to be lifted, such as assembled beams, are placed between the first clamping claw 2 and the second clamping claw 3 respectively, and then the two ends of the assembled beams are clamped and limited by appropriately adjusting the first clamping claw 2 and the second clamping claw 3; then the "lifting point position" is adjusted by adjusting the adjustment structure, and the assembled beam with limited clamping is lifted to the specified position of the assembled floor panel for easy construction.

[0033] Example 2

[0034] Based on Example 1, the sliding structure of the arrangement includes a sliding seat 4, which is hingedly arranged with the first movable connecting rod 21 and the second movable connecting rod 31 through an articulated seat, and the sliding seat 4 and the lifting and hoisting shoulder pole 1 are slidably arranged. At the same time, the top end of the first clamping claw 2 is hingedly connected with the top end of the movable limit hook 22, and the bottom end of the movable limit hook 22 is movably limited and hung on the limit pin, and the limit pin is fixedly connected to the middle of the second clamping claw.

[0035] Furthermore, the adjustment structure includes a first adjustment seat 11 and a second adjustment seat 12; the first adjustment seat 11 is slidably connected to one side of the lifting and hoisting pole 1, and the second adjustment seat 12 is slidably connected to the other side of the lifting and hoisting pole 1. A first connecting steel ring is hinged on the first adjustment seat 11, and a second connecting steel ring is hinged on the second adjustment seat 12. The first connecting steel ring and the second connecting steel ring are connected to a lifting hook 14 through a lifting wire rope 13. The lifting hook 14 is connected to an electric hoist through a steel chain, and the lifting and hoisting pole 1 is driven to move up and down by the electric hoist; the electric hoist is used to be installed and connected to the supporting connection structure.

[0036] In the embodiment, according to the size and dimension of the prefabricated component to be lifted (i.e., the center of gravity position), the relative positions of the first adjustment seat 11 and the second adjustment seat 12 on the lifting shoulder pole 1 are appropriately adjusted so that the first adjustment seat 11, the second adjustment seat 12, the lifting hook 14 and the lifting wire rope 13 used for lifting form a "triangle"; and the connection point between the lifting hook 14 and the lifting wire rope 13 is adjusted to form an "obtuse angle" to ensure the center of gravity position of the lifting and ensure that no tilting occurs during lifting. With manual assistance, the lifting and hoisting pole 1 is moved to a suitable position above the assembled component (assembled beam slab, box for containing bricks for masonry, etc.) that needs to be lifted, so that the first clamping claw 2 and the second clamping claw 3 of the two clamping structures are on both sides of the assembled component; then the assembled component is clamped and limited by adjusting the first clamping claw 2 and the second clamping claw 3 on both sides, and then a preliminary trial lifting is carried out, and the positions of the two clamping structures are adjusted according to the trial lifting, so that the center of gravity of the assembled component that is finally clamped and limited by the two clamping structures coincides with the center of gravity of the lifting and hoisting pole 1, that is, the lifting position is adjusted; then the formal lifting is carried out to lift the assembled component to the specified position of the floor panel of the assembled building. It should be noted here that during the formal lifting, the first adjustment seat 11, the second adjustment seat 12, and the two sliding seats 4 need to be fixed with bolts to prevent the center of gravity from shifting during lifting. There are also two clamping structures, a first clamping claw 2 and a second clamping claw 3. During the lifting process, due to the effect of gravity, the first clamping claw 2 and the second clamping claw 3 will "adaptively" clamp tighter and tighter, thereby firmly clamping the assembled component.

[0037] Example 3

[0038] The supporting and connecting structure of the arrangement includes a first horizontal telescopic adjustment arm 5 and a hollow second horizontal telescopic adjustment arm 6; one end of the first horizontal telescopic adjustment arm 5 is placed in the hollow cavity of the second horizontal telescopic adjustment arm 6, and a hydraulic cylinder is installed and connected in the hollow cavity of the second horizontal telescopic adjustment arm 6, and the first horizontal telescopic adjustment arm 5 is placed in one end of the hollow cavity of the second horizontal telescopic adjustment arm 6 and is connected to the output end rod body of the hydraulic cylinder, and the first horizontal telescopic adjustment arm 5 is driven to move horizontally and telescope along the hollow cavity of the second horizontal telescopic adjustment arm 6 through the extension and retraction of the hydraulic cylinder; the electric hoist is used to be installed and connected to the end of the first horizontal telescopic adjustment arm 5 away from the second horizontal telescopic adjustment arm 6 (the electric hoist is not drawn in the drawings of the specification), and the end of the second horizontal telescopic adjustment arm 6 away from the first horizontal telescopic adjustment arm 5 is hinged on the connecting structure, and the second horizontal telescopic adjustment arm 6 is also connected to a supporting structure for supporting and adjusting the second horizontal telescopic adjustment arm 6.

[0039] At the same time, the connection structure of the setting includes a connection support arm 7; the top of the connection support arm 7 is hinged to one end of the second horizontal telescopic adjustment arm 6 through a hinge seat, and the bottom end of the connection support arm 7 is rotatably connected to the lifting hydraulic rod 8 through a rotating connection plate (an existing electric rotating plate for controlling rotation), and the other end of the lifting hydraulic rod 8 is connected to a fixed steel plate, which is used to connect and fix the floor panel of the prefabricated building, and is used to stably support the entire lifting device. In addition, the support structure includes a support hydraulic rod 9; one end of the support hydraulic rod 9 is hinged to the middle bottom end of the second horizontal telescopic adjustment arm 6 through a hinge seat, and the other end of the support hydraulic rod 9 is hinged to one end of the connection support arm 7 close to the lifting hydraulic rod 8 through a hinge seat.

[0040] In the embodiment, the relative horizontal position between the first horizontal telescopic adjustment arm 5 and the second horizontal telescopic adjustment arm 6 is controlled by controlling the hydraulic cylinder arranged in the hollow cavity of the second horizontal telescopic adjustment arm 6, so as to ensure that, when lifting, the distance and position between the lifted prefabricated component and the outer facade of the prefabricated building can be kept to avoid collision with the outer facade of the prefabricated building, which can not only ensure that the prefabricated component is lifted to the specified position of the floor panel of the prefabricated building, but also ensure the quality of the prefabricated component. The prefabricated component is lifted to the floor panel by the electric hoist control, and then the first horizontal telescopic adjustment arm 5 of the connection structure is driven to rotate to a suitable position by controlling and adjusting the rotating connection plate, and the prefabricated component is lifted and moved to the specified position, and then lowered to the specified position. From the perspective of the structure of the lifting device improved by the design, the lifting device is a tool for lifting prefabricated building components between manual and large tower cranes. The lifting device is not only easy to install and disassemble, and the control operation is simple, but also the most important thing is that it can improve the lifting efficiency, save time, and ensure the progress of construction.
