During the manual handling and installation process, construction workers need to expend a lot of physical strength. They are prone to slipping or falling due to physical exhaustion or improper operation, which could lead to personal injury or death. If a hoisting platform is erected, the cost of hoisting the concrete columns is high. Utility Model Content

[0024] Example 1 like Figures 1-6 As shown, a hoisting device for concrete columns is specifically composed of a hoisting mechanism 3, a first support beam 1 for supporting the concrete columns, and a second support beam 2 for supporting the concrete columns. The first support beam 1 and the second support beam 2 are spaced apart, parallel to each other, and located on the same horizontal plane. The hoisting mechanism 3 is provided with a hoisting part 31 and a chain hoisting assembly 32. The two ends of the first support beam 1 are respectively connected to the chain hoisting assembly 32, and the two ends of the second support beam 2 are respectively connected to the chain hoisting assembly 32. The hoisting part 31 is used for detachable connection with hoisting equipment.

[0025] The concrete column is supported at one end by a first support beam 1 and at the other end by a second support beam 2. Multiple concrete columns can be placed on the first and second support beams 1 and 2 at the same time, improving handling efficiency. A hoisting mechanism 3 is connected to the hoisting equipment, which in turn connects to the first and second support beams 1 and 2, allowing the hoisting equipment to lift the first and second support beams 1 and 2 simultaneously, ensuring the concrete column is handled smoothly. The first and second support beams 1 and 2 are on the same horizontal plane, preventing the concrete column from tilting during hoisting and avoiding it falling. The simple hoisting platform formed by the first and second support beams 1 and 2 can be quickly assembled and used on the construction site; its simple structure and low cost make it suitable for use. Mechanical handling of the concrete columns reduces transport time, accelerates the overall construction progress, improves project efficiency, and allows the protective fence to be put into use more quickly. The hoisting device reduces labor costs, ensures worker safety, and is suitable for short-distance hoisting of concrete columns.

[0026] Specifically, the first support beam 1 and the second support beam 2 have the same structure.

[0027] In one or more embodiments, the first support beam 1 and the second support beam 2 are both square steel members. The top of the square steel member is provided with an abutment surface 8 for contacting the concrete column. The abutment surface 8 is a rough surface. The contact area between the concrete column and the square steel member is increased by the abutment surface 8. The friction between the concrete column and the abutment surface 8 is used to prevent the concrete column from falling during hoisting.

[0028] In an optional embodiment, the two ends of the square steel member are respectively provided with lifting lugs 6, and the chain hoisting assembly 32 is provided with a number of hook-shaped members 33. The hook-shaped members 33 are detachably connected to the lifting lugs 6. The detachable connection between the lifting lugs 6 and the hook-shaped members 33 makes it easy for the hoisting mechanism 3 to be connected and disassembled with the first support beam 1 and the second support beam 2, so as to facilitate the workers to place or remove the concrete column on the first support beam 1 and the second support.

[0029] In one or more embodiments, the chain-like lifting assembly 32 is composed of a first chain 321 and a second chain 322. The middle portion of the first chain 321 is connected to the lifting mechanism 3, and the middle portion of the second chain 322 is also connected to the lifting mechanism 3. Both ends of the first chain 321 are connected to the first support beam 1, and both ends of the second chain 322 are connected to the second support beam 2. Specifically, the first chain 321 includes a first chain segment 3211 and a second chain segment 3212, which are connected together. One end of the first support beam 1 is connected to the first chain segment 3211. The first support beam 2 is connected to the second support beam 2 at one end and to the second support beam 2 at the other end. The second support beam 2 is connected to the third support beam 2 at the other end and to the third support beam 3221 at the other end. The length of the first support beam 3211 is equal to the length of the second support beam 3212, and the length of the third support beam 3221 is equal to the length of the fourth support beam 3222. This makes the first support beam 1 horizontal and the second support beam 2 horizontal, preventing the concrete column from falling during transportation.

[0030] In an optional embodiment, the chain hoisting assembly 32 further includes a first support rod 4 and a second support rod 5. One end of the first support rod 4 is detachably engaged with a first chain segment 3211, and the other end is detachably engaged with a second chain segment 3212. One end of the second support rod 5 is detachably engaged with a third chain segment 3221, and the other end is detachably engaged with a fourth chain segment 3222. The first support rod 4 keeps the first chain segment 3211 and the second chain segment 3212 away from the concrete column, preventing the concrete column from being worn by the first chain segment 3211 or the second chain segment 3212 during hoisting. The second support rod 5 keeps the third chain segment 3221 and the fourth chain segment 3222 away from the concrete column, preventing the concrete column from being worn by the third chain segment 3221 or the fourth chain segment 3222 during hoisting.

[0031] In an optional embodiment, the first support rod 4 is provided with a first retaining member 41 and a second retaining member 42 at both ends. The first retaining member 41 is provided with a first opening groove 43, which engages with the first chain segment 3211. The second retaining member 42 is provided with a second opening groove 44, which engages with the second chain segment 3212. The second support rod 5 is provided with a third retaining member 51 and a fourth retaining member 52 at both ends. The third retaining member 51 is provided with a third opening groove 53, which engages with the third chain segment 3221. The fourth retaining member 52 is provided with a fourth opening groove 54, which engages with the fourth chain segment 3222. This facilitates the installation and removal of the first support rod 4 and the second support rod 5.

[0032] In an optional embodiment, the length of the first support rod 4 is greater than the length of the first support beam 1, and the length of the second support rod 5 is greater than the length of the second support beam 2, so that the first chain segment 3211 and the second chain segment 3212 are away from the concrete column, and the third chain segment 3221 and the fourth chain segment 3222 are away from the concrete column. Specifically, the length of the first support beam 1 is 1m, the length of the second support beam 2 is 1m, the length of the first support rod 4 is 1.2m, and the length of the second support rod 5 is 1.2m.

[0033] In one or more embodiments, a connecting rod 7 is provided between the first support beam 1 and the second support beam 2. One end of the connecting rod 7 is connected to the first support beam 1 and the other end is connected to the second support beam 2. The connecting rod 7 ensures that the spacing between the first support beam 1 and the second support beam 2 is stable, and prevents the concrete column from falling off during transportation.

[0034] In an optional embodiment, the length of the connecting rod 7 is less than the length of the concrete column, so that the first support beam 1 and the second support beam 2 can support the concrete column. The length of the concrete column is 1m, and the length of the support rod is 0.8m, so that one end of the concrete column can be placed on the first support beam 1 and the other end can be placed on the second support beam 2.

[0035] In this embodiment, a hoisting device for concrete columns is used by placing a first support beam 1 and a second support beam 2 on the ground, adjusting the distance between the first support beam 1 and the second support beam 2, and placing concrete columns so that one end of the concrete column abuts against the first support beam 1 and the other end abuts against the second support beam 2. After placing multiple concrete columns on the first support beam 1 and the second support beam 2, the hoisting device connects to the hoisting unit 31 to hoist the concrete columns.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
