Description

Technical Field

[0001] The utility model relates to the field of lifting and moving building concrete components, in particular to a concrete component lifting device. Background Art

[0002] Concrete components refer to various structural parts made of concrete materials and are widely used in buildings, bridges, roads, tunnels and other projects. According to different uses and designs, construction concrete components can be divided into:

[0003] Beam: A horizontal member used to support and distribute upper loads;

[0004] Column: vertical load-bearing member, mainly used to bear vertical loads;

[0005] Plate: A flat member commonly used in floors and roofs, bearing uniformly distributed loads;

[0006] Foundation: The base structure of a building, responsible for transferring loads to the foundation;

[0007] Wall: A vertical structure used to divide space and bear loads.

[0008] The design and construction of building concrete components must consider factors such as strength, durability, crack resistance, and construction technology. In modern architecture, precast concrete components are widely used due to their high construction efficiency and consistent quality. During construction, individual building concrete components are hoisted and assembled sequentially according to the intended assembly sequence, achieving rapid construction and reducing construction time.

[0009] At the construction site, when hoisting these building concrete components, the two ends of the building concrete components are basically tied together with the steel wire of the crane, and then directly hoisted and lifted by the crane. Using this hoisting method, the center of gravity of the building concrete component cannot be well balanced during hoisting, resulting in the building concrete component being easily tilted during hoisting, causing hoisting safety accidents due to unbalanced hoisting of the building concrete component.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 4 As shown, a concrete component lifting device is used to place building concrete components and lift and move the building concrete components to the construction site through the lifting device. The specific structure of the lifting device includes a placement base frame 1 for placing building concrete components, the bottom end of the placement base frame 1 is installed and connected with a connecting base plate 11 for strengthening the connection, and the top end of the placement base frame 1 is installed and connected with a plurality of parallel reinforced steel sections 12, and the reinforced steel sections 12 are all installed and connected to the placement base frame 1 by bolts; by reinforcing the connection between the placement base frame 1 and the plurality of reinforced steel sections 12 with the connecting base plate 11, the force of the entire lifting device is ensured, so that it has a more reliable bearing support force, and thus can achieve the placement and lifting of larger lifting building concrete components and the number of lifting times, thereby increasing the safety and service life of the entire device and achieving the purpose of saving costs and resources.

[0028] At the same time, both sides of the placement base 1 are connected with a limit structure with a movable adjustment setting. The limit structure is used to connect the wire rope 2 for lifting. The other end of the wire rope 2 is connected to the lifting pole 3 through a limit buckle 21.

[0029] In the embodiment, the placing base frame 1 and the lifting pole 3 are connected to the lifting pole 3 through four "adjustable" steel wire ropes 2 (two steel wire ropes on each side of the placing base frame 1); when lifting, the positions of the four limiting structures are adjusted according to the trial lifting, that is, the "angle" of the two steel wire ropes 2 on the same side can be adjusted, so that the positions of the four steel wire ropes 2 are adjusted according to the principle of center of gravity balance and the trial lifting, so as to ensure that when lifting, the placing base frame 1 is in a balanced state in the presence of the construction concrete components, so that the device is lifted by the crane, and the construction concrete components placed on the device are lifted to the construction site.

[0030] Furthermore, the limiting structures mentioned in the above embodiment are provided with four, one on each side of one end of the placement base; the limiting structures all include a limiting connection seat 4; one end of the limiting connection seat 4 is connected to one end of the support beam 13 by a bolt, and the limiting connection seat 4 is respectively hinged with a limiting rotation buckle 41, and the limiting rotation buckle 41 is respectively used to connect the lifting wire rope 2; the two supporting beams 13 are respectively connected to the two sides of the placement base 1 by bolts. When it is necessary to adjust the position of the four steel wire ropes 2 (the angle between the two steel wire ropes 2 on the same side and the supporting beam 13) according to the construction concrete components to be lifted, during a trial lift, the position of each limiting connection seat 4 is moved and adjusted according to the result of the trial lift, thereby adjusting the position of each steel wire rope 2, and ensuring that when the formal lifting is carried out, the entire device is in a balanced state when the construction concrete components are placed.

[0031] Furthermore, the two ends of the lifting pole 3 are detachably connected to the limit connection block 31 via bolts, and the two ends of the limit connection block 31 are respectively connected to the limit buckle 32, which is used to connect the lifting wire rope 2. The two ends of the top surface of the lifting pole 3 are detachably connected to the fixing seat 33 via bolts, and the fixing seat 33 is used to connect the lifting wire rope 5. The other ends of the lifting wire rope 5 are respectively connected to the lifting hook buckle 51. The two lifting hook buckles 51 are used to hang on the lifting hook of the crane. During lifting, the lifting hook buckles 51 of the two lifting wire ropes 5 are used to hang on the lifting hook of the crane, so that the entire device can be "balanced lifted" by the crane. It should be noted that, in order to prevent the building concrete components from falling off the top surface of the placement base 1 of the device during lifting, limit clamps are respectively provided around the top of the placement base 1. The limit clamps are detachably connected to the placement base 1 by bolts (the limit clamps are not shown or marked in the accompanying drawings). This lifting device is not only simple in structure, inexpensive, with readily available materials and convenient splicing and construction, but also can achieve stable adjustment of the center of gravity through the lifting device, ensuring the balance of the lifted building concrete and avoiding the occurrence of lifting safety accidents.
