Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of autoclaved aerated concrete block hoisting, in particular to an autoclaved aerated concrete block hoisting device. BACKGROUND

[0002] In the secondary structure masonry construction of building engineering, autoclaved aerated concrete blocks are widely used due to their light weight, thermal insulation and easy processing. Since the working surface is usually located at a high floor level, the aerated concrete blocks need to be transported from the ground to the working layer by vertical transportation. The commonly used method is to place the aerated concrete blocks on a tray, and then use a tower crane or a construction elevator to hoist the whole tray. Although this method improves the transportation efficiency to a certain extent, it puts higher requirements on the stability of the connection between the tray and the cage, and the reliability of the fixation of the aerated concrete blocks during transportation, especially under complex working conditions such as frequent hoisting, high-altitude operation and wind load interference, the safety risk is particularly prominent.

[0003] In the prior art, the aerated concrete block tray is temporarily fixed in the cage by packaging ropes or straps, and some cages only rely on the bottom support or simple enclosure to limit the displacement of the tray. This structure design relies on manual lashing and lacks rigid limiting measures, and in actual use, the aerated concrete blocks are prone to sliding due to rope loosening, tray deviation or shaking, which poses a serious safety hazard. At the same time, due to the differences in thickness and size of the trays used in different projects, the fixing structure is not universal, resulting in poor adaptability of the device, and the hoisting needs to be adjusted or reinforced every time, affecting the construction efficiency. In addition, if the space for inserting the limiting member is not reserved during loading and unloading, the operation is complicated and time-consuming, further restricting the smoothness of the hoisting operation.

[0004] Therefore, it is urgent to provide an autoclaved aerated concrete block hoisting device to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] like Figures 1 to 5 As shown, one embodiment of the present invention is a carboxylated block hoisting device, which includes a cage body 1, a first limiting mechanism 2, a pallet body 3, and a second limiting mechanism 4.

[0026] The pallet body 3 is located at the bottom inside the cage body 1 and is used to carry the autoclaved aerated concrete blocks. There is a gap between the outer side of the pallet body 3 and the inner side of the cage body 1. The first limiting mechanism 2 is movably inserted into the pallet body 3 and connected to the cage body 1 to realize the quick assembly, disassembly and positioning between the cage body 1 and the pallet body 3.

[0027] The second limiting mechanism 4 is installed on both sides of the bottom of the square steel frame 11 at the bottom of the cage body 1. It is used to limit the lateral position of the pallet body 3 in the cage body 1, and the limiting height can be adjusted according to the pallet thickness.

[0028] The cage body 1 includes a bottom square steel frame 11, side enclosures 12, and a top square steel frame 13. The bottom square steel frame 11 is a rectangular metal frame structure used to support the entire cage and bear the load. The side enclosures 12 are welded and installed around the upper part of the bottom square steel frame 11 to form a semi-enclosed box structure. Top lifting lugs 122 are welded and installed on the upper front and rear sides of the side enclosures for connecting with lifting equipment. Round steel lifting rings 121 are welded and installed on the lower front and rear sides of the side enclosures for the first limiting mechanism 2 to pass through. At the same time, steel mesh is also welded to the outside of the side enclosures 12 to seal the internal space of the cage and prevent the aerated concrete blocks on the pallet from scattering during transportation.

[0029] The top square steel frame 13 is welded and installed on the top of the side enclosure 12 to enhance the overall rigidity of the cage and to cooperate with the top lifting lugs 122 to complete the lifting operation.

[0030] The pallet body 3 includes a bottom plate 31, a support plate 32, and a top support 33. The bottom plate 31 serves as the basic bearing surface of the pallet body 3. The support plate 32 is located on top of the bottom plate 31 to enhance the overall strength and stability of the pallet body 3. The top support 33 is horizontally positioned on the upper surface of the bottom plate 31 via the support plate 32. It consists of multiple parallel strip-shaped components and is used to directly support the autoclaved aerated concrete blocks. A gap is left between the top support 33 and the bottom plate 31 via the support plate 32 to facilitate the insertion and removal of the first limiting mechanism 2.

[0031] The first limiting mechanism 2 comprises a supporting steel pipe 21, a first bolt 22 and a first nut 23; the supporting steel pipe 21 is a hollow cylindrical pipe, and a through hole is formed in the outer wall of each end of the pipe; the first bolt 22 is screwed into the first nut 23 after penetrating through the through hole of the end of the supporting steel pipe 21; specifically, the two ends of the supporting steel pipe 21 penetrate through the side of the tray body 3 and extend into the round steel lifting ring 121 below the lateral enclosure 12, and the first bolt 22 and the first nut 23 are fastened to limit the supporting steel pipe 21 from falling off after penetrating through the round steel lifting ring 121, thereby achieving the connection and limiting function of the cage body 1 being sleeved on the outside of the top of the tray body 3.

[0032] The second limiting mechanism 4 is installed on both sides of the bottom square steel frame 11, and is used for limiting the horizontal movement of the tray body 3 in the cage body 1; the second limiting mechanism 4 comprises a limiting block 41, a second bolt 42 and a second nut 43; the limiting block 41 is vertically welded to the bottom of the second bolt 42, the second bolt 42 is screwed into the second nut 43 welded to the inner side of the bottom square steel frame 11, and the length of the second bolt 42 can be adjusted by rotating the limiting block 41, thereby adjusting the height of the bottom of the limiting block 41 to adapt to the tray body 3 of different thicknesses and facilitate the insertion of the first limiting mechanism 2.

[0033] When the cage body 1 is sleeved on the tray body 3, the side surface of the limiting block 41 is in contact with the side surface of the tray body 3, thereby achieving horizontal limiting and preventing the tray from deviating or shaking during lifting.

[0034] During operation, first, the autoclaved aerated concrete blocks to be lifted are neatly placed on the top support 33 of the tray body 3 to ensure that the gravity center is evenly distributed; Then, the cage body 1 is lifted to the outside of the tray body 3, so that the tray body 3 is located directly above the bottom square steel frame 11; then, according to the actual thickness of the tray body 3, the height of the limiting block 41 in the second limiting mechanism 4 is adjusted so that the bottom of the limiting block 41 is tightly fitted with the side of the tray body 3, horizontal limiting is completed, and a gap is exposed for the insertion of the first limiting mechanism 2; Then, the two ends of the supporting steel pipe 21 of the first limiting mechanism 2 penetrate through the side of the tray body 3 and are inserted into the round steel lifting ring 121 below the lateral enclosure 12 in sequence, and the two ends of the supporting steel pipe 21 and the round steel lifting ring 121 are limited by the first bolt 22 and the first nut 23, thereby stably sleeving the cage body 1 on the outside of the top of the tray body 3; Finally, the cage body 1 is connected with the lifting equipment through the top lifting lug 122, the lifting operation is started, and the safe and efficient transportation of the autoclaved aerated concrete blocks is realized.

[0035] The first limiting mechanism 2 and the second limiting mechanism 4 are detachable and adjustable, so that the cage body 1 and the tray body 3 are quickly assembled and accurately positioned, and the problems of low assembly and disassembly efficiency and easy falling caused by the single fixing mode of the traditional lifting appliance are avoided; meanwhile, the steel mesh is closed, so that the aerated block is effectively prevented from falling during transportation, and the construction safety and operation efficiency are improved. Embodiment two

[0036] As shown in Figures 1 to 5 The first limiting mechanism 2 and the second limiting mechanism 4 are further optimized in the embodiment based on the embodiment one, and the rest of the structure is the same as that of the embodiment one. The specific optimization is as follows: The supporting steel pipe 21 is made of high-strength carbon steel, and the through holes formed in the outer walls of the two ends are slightly larger in diameter than the diameter of the first bolt 22, so that a certain gap is reserved to allow fine adjustment of the installation position and improve the assembly flexibility; the first bolt 22 is a hexagonal head bolt, which is used in cooperation with a hexagonal nut 23, so that the first bolt 22 is quickly tightened manually or by a tool, and the operation efficiency is improved; the second bolt 42 is designed with a fine thread, so that the length of the thread engagement is increased, and the limiting accuracy and anti-loosening ability are improved.

[0037] In addition, the welding parts between the lateral enclosure 12 and the bottom square steel framework 11 and the top square steel framework 13 are all full-welded, so as to ensure the overall strength of the structure; the round steel lifting ring 121 and the top lifting lug 122 are both heat-treated to improve the tensile performance; and the grid spacing of the steel mesh is controlled within 50 mm, so as to effectively prevent the aerated block from falling.

[0038] The embodiment optimizes the material selection and connection details, significantly improves the overall durability and operation convenience of the device, and is especially suitable for construction sites where the tray is frequently replaced, and has good practicality and promotional value.
