Concrete blocks mainly include small hollow concrete blocks, small hollow light aggregate concrete blocks, autoclaved aerated concrete blocks and foam concrete blocks. Generally speaking, the number of concrete blocks for the interior and exterior walls of building structures is large, and workers usually directly lift the blocks after bundling them. This lifting method makes it easy for the blocks to fall freely, which makes the lifting work have great safety hazards. In this regard, the prior art has designed a hoisting cage device with an upper opening (or a side opening). Before lifting, the staff loads the blocks into the hoisting cage device from the upper opening. When the blocks are lifted to the predetermined location, the staff takes out the blocks from the upper opening to complete the final transportation of the blocks. Compared with the traditional method of directly lifting the blocks after bundling, the hoisting of blocks through the hoisting cage device with an upper opening has higher safety and also improves the lifting efficiency.
[0003] However, the lifting device with an opening on the top has certain technical defects, such as the need for secondary transportation of blocks, which is time-consuming and labor-intensive, and the lifting efficiency is low.

[0034] The main frame assembly 1 is used to carry or install various parts of the cage device and bear the weight of the blocks as the main load-bearing member;
[0035] In this embodiment, the main frame assembly 1 includes a vertical steel pipe 11 and a horizontal top pipe 12 and a horizontal bottom pipe 13 respectively connected to both ends of the vertical steel pipe 11 .
[0036] It should be noted that, in the specific implementation process, the number of vertical steel pipes 11 is four, serving as the vertical body of the main frame assembly 1. Four horizontal top pipes 12 are welded to the top of the vertical steel pipe 11, and four horizontal bottom pipes 13 are welded to the bottom. Thus, these twelve steel pipes form a frame body of a cubic structure.
[0037] It should be further explained that, in some embodiments, the connection method between the vertical steel pipe 11 and the horizontal steel pipes at both ends can be selectively set according to actual conditions, and is not limited to welding. For example, it can be a detachable threaded connection, or a snap connection. The three can also be set into an integrally formed structure to obtain stronger supporting capacity and higher stability. No specific limitation is made here.
[0038] Furthermore, in this embodiment, the main frame assembly 1 also includes a cross beam 14 arranged at one end of the vertical steel pipe 11 close to the horizontal bottom pipe 13. Both ends of the cross beam 14 are connected to the vertical steel pipe 11 and are spaced apart from the horizontal bottom pipe 13 to facilitate free pushing in or pulling out of the push-pull chassis 6.
[0039] It should be noted that, in the specific implementation process, there are two cross beams 14 , which are arranged on both sides of the cage device. The two cross beams 14 are connected to the vertical steel pipe 11 by electric welding, and both ends of the two cross beams 14 are perpendicular to the vertical steel pipe 11 .
[0040] It should be further explained that, in some embodiments, the connection relationship between the cross beam 14 and the vertical steel pipe 11 can also be selectively set according to actual conditions, and is not limited to the electric welding connection method. For example, the two can be fixed by bolt connection, pin connection and other connection methods, which are not specifically limited here.
[0041] In this embodiment, the fixing pin 7 is disposed through the cross beam 14 and matches with the fastening hole 8 provided on the push-pull chassis 6 .
[0042] It should be noted that, in the specific implementation process, the fixing pins 7 are fixing pins, and each cross beam 14 has two fixing pins, and the four fixing pins are distributed in a matrix and correspond to the four fastening holes 8 respectively.
[0043] It should be noted that, in the specific implementation process, the fixing pin is an L-shaped structure, and the push-pull chassis 6 can be locked by rotating the fixing pin clockwise for several turns to prevent the push-pull chassis 6 from loosening or falling out during the lifting process, thereby preventing the building blocks from scattering and falling out, thereby improving the work efficiency and safety of the lifting; the locked push-pull chassis 6 can be unlocked by rotating the fixing pin counterclockwise for several turns, making it in an active state, so that the staff can push it in or pull it out freely.
[0044] It should be further explained that, in some embodiments, the type, quantity and structural shape of the fixing pin 7 can be selectively set according to actual conditions and are not specifically limited here.
[0045] A lifting ring 2 is provided on the top of the main frame assembly 1 and is used for connecting with a lifting belt of a crane;
[0046] In this embodiment, four lifting rings 2 are welded to the top of the vertical steel pipe 11 , and the four lifting rings 2 are distributed in a matrix.
[0047] It should be noted that, in the specific implementation process, the lifting ring 2 includes a lifting handle and a circular ring, which are integrally formed and are both made of steel; wherein the lifting handle is connected to the vertical steel pipe 11 by electric welding, and the circular ring is used to connect to the lifting belt of the crane, and the connection methods include but are not limited to binding, hooking, etc.
[0048] A first bracket 3 is mounted on the bottom of the main frame assembly 1;
[0049] In this embodiment, the push-pull chassis 6 is disposed at the bottom of the main frame assembly 1 and abuts against the first bracket 3;
[0050] It should be noted that, in the specific implementation process, the first bracket 3 is two square steel pipes, which are welded on both sides of the bottom of the main frame assembly 1, and form a ladder shape with the steel pipe at the bottom of the main frame assembly 1. The two first brackets 3 maintain a sufficient distance to ensure that the building blocks can pass through the bottom surface of the cage main frame assembly 1.
[0051] It should be noted that, in some embodiments, the material and shape of the first bracket 3 and the connection method with the square steel pipe at the bottom of the main frame assembly 1 can be selectively set according to actual conditions and are not specifically limited here.
[0052] The second bracket 4 is arranged at the bottom of the main frame assembly 1 and located above the first bracket 3, and a temporary support pipe 5 is arranged on the second bracket 4;
[0053] It should be noted that, in the specific implementation process, the temporary support pipe 5 is two round steel pipes, and in the lifting process, the temporary support pipe 5 plays the role of bearing the weight of the concrete block. When the concrete block is lifted to the top of the wooden support at the predetermined location, the temporary support pipe 5 is pulled out to lift the cage device upward as a whole.
[0054] In this embodiment, the push-pull chassis 6 is detachably arranged on the main frame assembly 1 through four fixing pins.
[0055] It should be noted that, in the specific implementation process, after the crane lifts the building blocks to the predetermined location, the push-pull chassis 6 is pulled out (at this time, the bottom surface of the cage device is about 50 cm from the ground), and the building blocks together with the bottom wooden support can be placed at the predetermined location.
[0056] In this embodiment, the main frame assembly 1 further includes a first protection net 15, and the first protection net 15 is cross-formed on four sides of the cage device.
[0057] It should be noted that, in the specific implementation process, the first protection net 15 on each side is formed by a plurality of round steel bars that penetrate and are welded and fixed on the square steel pipe of the main frame assembly 1. The provision of the first protection net 15 can prevent the blocks from freely falling during the lifting process, thereby improving the safety of the lifting work.
[0058] It should be noted that, in some embodiments, the material and shape of the first protective net 15 can be selectively set according to actual conditions, and no specific limitation is made here.
[0059] In this embodiment, if Figure 2 As shown, the push-pull chassis 6 includes a chassis outer frame 61 , an inner frame 62 and a second protection net 63 ; wherein the second protection net 63 is cross-formed in the outer frame 61 under the support of the inner frame 62 .
[0060] It should be noted that, in the specific implementation process, the outer frame 61, the inner frame 62 and the second protective net 63 form a push-pull chassis 6 with multiple grid structures. The second protective net 63 is composed of multiple steel wires, which can prevent the building blocks from falling out from the bottom of the cage device. Among them, the inner frame 62 can enhance the endurance of the first protective net 15.
[0061] It should be noted that, in some embodiments, the material and shape of the second protective net 63 can be selectively set according to actual conditions, and no specific limitation is made here.
[0062] In this embodiment, handles 9 are provided on both sides of the push-pull chassis 6 .
[0063] It should be noted that, in a specific implementation process, the push-pull chassis 6 can be quickly pulled out from the bottom of the main frame assembly 1 or the push-pull chassis 6 can be pushed into the bottom of the main frame assembly 1 through the handle 9 .
[0064] The working principle or operation process of this embodiment is as follows:
[0065] 1) Lift the cage device to the top of the concrete block;
[0066] 2) Pull out the push-pull chassis 6 from the bottom of the cage device to cover the concrete blocks from top to bottom;
[0067] 3) Pass the temporary support pipe 5 through the hole reserved in the middle of the block (such as Figure 3 As shown) supported on the second bracket 4 on both sides of the cage device;
[0068] 4) Check the key parts such as the welds of the cage device to ensure the safety of the lifting process;
[0069] 5) When the cage device is lifted to a height of about 50 cm from the ground, the push-pull chassis 6 is pushed into the cage device, four fixing pins are inserted, and the concrete blocks are lifted to the predetermined location;
[0070] 6) After the concrete blocks reach the top of the predetermined location, the cage device is lowered to about 50 cm from the ground, and the fixing pins are unlocked to pull out the push-pull chassis 6;
[0071] 7) After the concrete blocks are hoisted to the predetermined location, the temporary support pipe 5 is pulled out, and then the hoist cage device is hoisted upward as a whole to complete the hoisting.
[0072] It should be further explained that, in the specific implementation process, the force transmission principle of the cage device is as follows: during lifting, the concrete blocks are tied together with the wooden pallet at the bottom and firmly placed on the push-pull chassis 6, and the load is transferred to the second bracket 4 by the temporary support pipe 5, and then the load is transferred from the vertical steel pipe 11 of the main frame assembly 1 of the cage to the lifting ring 2, and finally to the sling of the crane.
[0073] In summary, compared with the prior art, this embodiment has the following technical effects:
[0074] (1) By setting the fixing pin 7 and the push-pull chassis 6 at the bottom of the cage device, that is, the bottom of the cage device is open at the bottom, when the blocks are hoisted into place, the push-pull chassis 6 can be pulled out by quickly unlocking the fixing pin 7, and then the cage device can be hoisted upward as a whole, avoiding the secondary transportation of blocks, and having the advantages of convenient and quick disassembly and assembly;
[0075] (2) The cage structure can limit the displacement of the blocks. The first protection net 15 and the second protection net 63 can effectively prevent the blocks from falling freely, thereby improving the safety of the lifting work.
[0076] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
