Description

Technical Field

[0001] This utility model relates to the technical field of hoisting aerated concrete blocks, and in particular to a hoisting cage for hoisting aerated concrete blocks. Background Technology

[0002] Material handling at construction sites, especially the horizontal and vertical handling of aerated concrete blocks, is a crucial aspect of ensuring construction progress and efficiency. Currently, the following two handling methods are mainly used on construction sites:

[0003] One method is mechanical collaborative hoisting and transportation. First, a forklift is used to transport the aerated concrete blocks horizontally on pallets to the designated hoisting point within the coverage area of ​​the tower crane. Then, special hoisting straps are used to tie and fix the blocks. Next, the tower crane performs vertical hoisting, accurately placing the blocks onto the unloading platform of the target floor. Finally, a handcart is used to complete the horizontal transfer of the blocks from the unloading platform to the work point.

[0004] Another method is a human-machine combined elevator transfer method, which relies entirely on manual labor to move aerated concrete blocks from pallets to electric transfer carts; the construction elevator is used to complete the vertical transportation of the blocks to the target floor; after arriving at the floor, the blocks are unloaded from the electric transfer carts again by manual labor and transported to the work site.

[0005] However, in actual use, it was found that both of the above-mentioned horizontal and vertical transport methods for aerated concrete blocks require the aerated concrete blocks placed on pallets by the manufacturer to be moved into trolleys before being transported. This requires a second loading of the aerated concrete blocks, which wastes a lot of labor costs and even affects the continuity of the work process for bricklayers. Utility Model Content

[0006] To address the shortcomings in the aforementioned background technology, this utility model proposes a hoisting cage for transporting aerated concrete blocks, which solves the technical problem that the transfer of existing aerated concrete blocks requires secondary loading using trolleys, affecting the continuity of the masonry workers' work processes.

[0007] The technical solution of this utility model is implemented as follows: A hoisting cage for transporting aerated concrete blocks includes a box body and fixing bolts. The top and bottom of the box body are provided with openings adapted to the size of the pallet. A hoisting unit is provided at the opening at the top of the box body. A first connecting ring and a second connecting ring are provided at the opening at the bottom of the box body. The first connecting ring and the second connecting ring are symmetrically arranged on two opposite sides of the box body. A moving unit is connected to the bottom of the box body. After the box body is fitted over the aerated concrete blocks, the rod of the fixing bolt passes through the first connecting ring, the pallet for placing the aerated concrete blocks, and the second connecting ring in sequence and is connected to the fixing nut. The lifting cage of this application is directly compatible with the pallet size. It can be directly fitted onto the outside of the pallet holding the aerated concrete blocks. The fixing bolts pass sequentially through the first connecting ring, the pallet holding the aerated concrete blocks, and the second connecting ring, connecting to the fixing nut. This securely connects the lifting cage and the pallet to form a single unit, allowing for the lifting and transport of the entire aerated concrete block assembly using a tower crane. This eliminates the need for secondary loading using trolleys, saving labor costs and preventing disruption to the bricklaying workers' workflow due to transport inefficiency. This solves the technical problem of existing aerated concrete block transport methods requiring secondary loading using trolleys, which affects the continuity of bricklaying workers' work.

[0008] The hoisting unit is designed to facilitate connection with the tower crane, enabling the tower crane to hoist the cage. Once the cage is fixedly connected to the pallet holding the aerated concrete blocks to form a whole, the tower crane is used to hoist this whole unit to the unloading platform on the target floor.

[0009] The moving unit is designed to facilitate the movement of the hoisting cage. Once the hoisting cage and the pallet holding the aerated concrete blocks are hoisted by the tower crane to the unloading platform on the target floor, the moving unit can be used to move the hoisting cage and the pallet holding the aerated concrete blocks to the work point.

[0010] Preferably, the box body is rectangular; the box body includes multiple uprights and multiple crossbars, the multiple uprights are parallel to each other and enclose a rectangle adapted to the size of the pallet, and the multiple crossbars are vertically fixed to the uprights and enclose a rectangle. The multiple uprights and multiple crossbars are welded to form a rectangular box body, and the rectangular box body is adapted to the size of the pallet. This arrangement allows the box body to be directly fitted onto the pallet holding aerated concrete blocks.

[0011] Preferably, at least two first connecting rings and at least two second connecting rings are provided at the opening at the bottom of the box. After the box is fitted over the aerated concrete blocks, the shank of the fixing bolt passes through the first connecting ring, the tray holding the aerated concrete blocks, and the second connecting ring in sequence, and is connected to the fixing nut. The purpose of providing at least two first connecting rings and at least two second connecting rings at the bottom of the box is to allow the shanks of at least two fixing bolts to pass through the first connecting ring, the tray holding the aerated concrete blocks, and the second connecting ring in sequence, and to be connected to the fixing nut. This achieves the purpose of using at least two fixing bolts to fix the tray holding the aerated concrete blocks to the box to form a whole, thereby increasing the connection strength between the tray holding the aerated concrete blocks and the box.

[0012] Preferably, wire mesh is connected along the front, rear, left, and right sides of the cage. The wire mesh is provided to protect the front, rear, left, and right sides of the cage, which helps to improve the safety performance during the hoisting process.

[0013] Preferably, one side of the housing is a discharge port for unloading aerated concrete blocks, and the wire mesh at the discharge port is detachably connected to the housing. This arrangement allows the wire mesh at the discharge port to be opened when the cage and the pallet holding the aerated concrete blocks are moved to the work site via a moving unit, facilitating the unloading of the aerated concrete blocks by workers.

[0014] Preferably, one end of the wire mesh at the discharge port is connected to the housing via a hinge, and the other end is connected to the housing via a pin. The hinge is hinged to a vertical rod at one end of the housing to achieve the hinged connection between the wire mesh at the discharge port and the housing. The pin is used to limit and fix the wire mesh at the discharge port to the housing. The pin includes a ring and a horizontally movable rod. The horizontally movable rod is fixed to the wire mesh, and the ring is fixedly connected to the vertical rod of the housing. When the rod moves horizontally to the right and inserts into the ring, the wire mesh at the discharge port is fixed to the housing, thus closing the discharge port. When the rod moves horizontally to the left and disengages from the ring, the wire mesh at the discharge port is disengaged from the housing, thus opening the discharge port.

[0015] Preferably, the housing is connected to at least two fixing rods, which are symmetrically arranged on the front and rear sides of the housing. The first connecting ring is fixedly connected to the bottom of the fixing rod on the front side of the housing, and the second connecting ring is fixedly connected to the bottom of the fixing rod on the rear side of the housing. The fixing rods improve the connection strength of the housing, and the fact that both the first and second connecting rings are welded to the fixing rods further enhances their fixation strength to the housing. Both the first and second connecting rings are made of steel pipe.

[0016] Preferably, the hoisting unit includes connecting bolts and several lifting rings. The lifting rings are symmetrically arranged on two sides of the opening at the top of the cage. The shank of the connecting bolt passes through the lifting rings on the two opposite sides and is then connected to the connecting nut. The lifting rings are symmetrically arranged on two sides of the opening at the top of the cage, and the lifting rings on the two sides are fixedly connected by the connecting bolts. Then, the entire cage can be hoisted by hooking the connecting bolts with hooks on the tower crane.

[0017] The first connecting ring, the second connecting ring, and the lifting ring have the same structure. The lifting ring is also made of steel pipe. The fixing bolt and the connecting bolt are the same type of bolt, and the fixing nut and the connecting nut are also the same.

[0018] Preferably, several lifting rings are respectively connected to the top of the fixing rod on the front side of the box and the top of the fixing rod on the rear side of the box, and the number of lifting rings is the same as the number of fixing rods. The lifting rings are welded and fixed to the top of the fixing rods to improve the strength of the lifting rings fixed to the box.

[0019] Preferably, the moving unit includes casters with braking function, which are connected to the bottom of the housing. The casters are designed to move the cage and the pallet holding the aerated concrete blocks to the work point. The rollers on the casters with braking function directly contact the ground, providing the moving function, and the brackets on the casters are threadedly connected to the bottom of the housing. Casters with braking function refer to casters equipped with either a foot brake or a hand brake. Casters with braking function can be heavy-duty 6-inch 350kg flat-top iron double-brake TPE (thermal polyethylene) casters.

[0020] The beneficial effects of this utility model are as follows: The cage of this application is directly adapted to the size of the pallet. The cage can be directly fitted onto the outside of the pallet holding the aerated concrete blocks. The rod of the fixing bolt passes through the first connecting ring, the pallet holding the aerated concrete blocks, and the second connecting ring in sequence and is connected to the fixing nut, so that the cage and the pallet holding the aerated concrete blocks are fixedly connected to form a whole. Then, the tower crane can be used to lift this whole, so as to realize the hoisting and transportation of the aerated concrete blocks as a whole. There is no need to use a trolley for secondary loading, saving labor costs and avoiding the situation where the work continuity of the bricklaying workers is affected by the transportation efficiency.
