[0002] In the construction industry, precast concrete blocks refer to cement concrete precast blocks with a three-dimensional interlocking structure, which are assembled at the construction site and filled with grouting material in the joints. The application of precast concrete blocks is becoming increasingly widespread. Using precast concrete components has advantages such as controllable quality and fast construction speed during the construction process. During the assembly process, a lifting fixture is required to lift and transport the precast concrete blocks. It must be able to bear the weight of the blocks and various forces during the lifting process, while ensuring the stability and safety of the blocks during lifting and transportation.

[0003] The existing installation method needs to cooperate with a crane and requires four-direction fixation before use. Due to the large size and heavy weight of precast concrete blocks, there are problems such as difficult movement, stacking, and installation. It may be difficult to control the direction during the lifting process, resulting in the block falling off or tilting during lifting, thus triggering a safety accident. This will not only cause casualties and property losses but may also affect the construction progress and quality and reduce work efficiency.

[0021] The present utility model will be further described below with reference to the drawings and embodiments.

[0022] Please refer toFigures 1 - 4 , the present utility model provides an embodiment: a hoisting fixture for precast concrete base blocks used in building construction, which includes a base 1, a clamping module, and a hoisting module; on both sides above the base 1, clamping modules for clamping precast concrete base blocks are symmetrically provided, and in the middle of the base 1, a hoisting module for telescoping and driving the clamping module to rotate and clamp is installed. The clamping module includes a rotating frame 201, a rotating ring sleeve 202, a rotating shaft 203, a U-shaped connecting frame 204, clamping pieces 205, a first connecting ring 206, a first iron chain 207, a first movable ring buckle 208, and a first fixing pin 209. Below one end of the rotating frame 201, a U-shaped connecting frame 204 is installed, and clamping pieces 205 are installed inside the U-shaped connecting frame 204. A rotating ring sleeve 202 is penetrated through the position of the rotating frame 201 close to the U-shaped connecting frame 204. Above one end of the rotating frame 201 away from the U-shaped connecting frame 204, a first connecting ring 206 is installed. Above the first connecting ring 206, a first iron chain 207 is provided. First movable ring buckles 208 are provided at the connection positions of the first iron chain 207 with the first connecting ring 206 and the hoisting module.

[0023] Please refer to Figure 2 , in this embodiment, a limiting rod 101 is installed on one side of the base 1, and U-shaped handrails 103 are symmetrically provided at both ends above the base 1. Rectangular plug-in sleeves 102 fixedly connected to the base 1 are sleeved outside both ends of the U-shaped handrails 103. First, place the base 1 on the base block. During the operation of the clamping module, place the limiting rod 101 at the edge of the base block for limiting, and clamp and fix the base block. When it is necessary to control the moving direction of the base block, pick up the U-shaped handrail 103, and respectively insert and position-connect its two ends with the rectangular plug-in sleeves 102, and then manually rely on pushing and pulling the U-shaped handrail 103 to more accurately control the moving direction of the base block.

[0024] Please refer to Figure 3 , in this embodiment, a rotating shaft 203 is sleeved inside the rotating ring sleeve 202. When the hoisting module telescopes, the first iron chain 207 is forced to move upward, and then pulls the rotating frame 201. The rotating frame 201 rotates along the rotating shaft 203 through the rotating ring sleeve 202. Both the rotating shaft 203 and the rotating ring sleeve 202 pass through the base 1. Thus, the U-shaped connecting frame 204 drives the clamping pieces 205 to continuously approach and fit the base block to clamp and fix the base block. A first fixing pin 209 is penetrated through the first movable ring buckle 208. First, pick up the first movable ring buckle 208, position-connect the first connecting ring 206 and the first iron chain 207, and then fix them with the first fixing pin 209.

[0025] Please refer to Figure 4, in this embodiment, the lifting module includes a circular telescopic sleeve 301, a support column 302, a circular telescopic column 303, a second connecting ring 304, a second movable ring buckle 305, a second fixing pin 306, a second iron chain 307 and a combined connecting ring 308. Four groups of support columns 302 fixedly connected to the base 1 are circumferentially installed outside the circular telescopic sleeve 301. A circular telescopic column 303 is sleeved inside the circular telescopic sleeve 301. A second connecting ring 304 is installed at the upper end of the circular telescopic column 303. First, take out the second movable ring buckle 305, positionally connect the second connecting ring 304 with the second iron chain 307, and then fix it with the second fixing pin 306. There is a second iron chain 307 above the second connecting ring 304, and a combined connecting ring 308 is provided above the second iron chain 307. Second movable ring buckles 305 are provided at the connection positions of the second iron chain 307 with the second connecting ring 304 and the combined connecting ring 308. A second fixing pin 306 is inserted through the second movable ring buckle 305. Take out another second movable ring buckle 305, positionally connect the combined connecting ring 308 with the second iron chain 307, and then fix it with the second fixing pin 306. Then, the construction machinery hooks the combined connecting ring 308, and the circular telescopic column 303 moves upward along the circular telescopic sleeve 301.

[0026] When working, first place the base 1 on the base block, then pick up the first movable ring buckle 208, positionally connect the first connecting ring 206 with the first iron chain 207, and then fix it with the first fixing pin 209. Then, take out another first movable ring buckle 208, positionally connect the combined connecting ring 308 with the first iron chain 207, and then fix it with the first fixing pin 209. Immediately afterwards, take out the second movable ring buckle 305, positionally connect the second connecting ring 304 with the second iron chain 307, and then fix it with the second fixing pin 306. Then, take out another second movable ring buckle 305, positionally connect the combined connecting ring 308 with the second iron chain 307, and then fix it with the second fixing pin 306;

[0027] When all the assemblies are completed, the construction machinery hooks the combined connecting ring 308, and the circular telescopic column 303 moves upward along the circular telescopic sleeve 301. When the circular telescopic column 303 expands and contracts, the first iron chain 207 is forced to move upward, then pulls the rotating frame 201, and the rotating frame 201 rotates along the rotating shaft 203 through the rotating ring sleeve 202. Thus, the U-shaped connecting frame 204 drives the clamping piece 205 to continuously approach and fit the base block. At the same time, the limiting rod 101 is placed at the edge of the base block for limiting, and the base block is clamped and fixed;

[0028] When it is necessary to control the moving direction of the base block, pick up the U-shaped handrail 103, insert and positionally connect its two ends with the rectangular socket sleeve 102 respectively, and then the operator relies on pushing and pulling the U-shaped handrail 103 to more accurately control the moving direction of the base block.

[0029] Through the above steps, first place the base 1 on the precast concrete block. Then, the construction machinery drives its expansion and contraction through the hook hanging and lifting module. At the same time, the clamping module cooperates with the limiting rod 101 on one side of the base 1 to clamp and fix the precast concrete block. Then, it is lifted and moved. By this method, the clamping module utilizes the self-weight of the precast concrete block and the lifting module to achieve the function of fixing the direction, realizing convenient movement, improving work efficiency. At the same time, the limiting rod 101 fixes the block, ensuring the safety of the staff. The fixed size and large self-weight of the precast concrete block become advantages. In addition, the use of the clamping module is simple and easy, and it is convenient to use. Therefore, it can be widely applied to various places where concrete precast components need to be installed, moved, and stacked, so as to solve the problems that the existing installation method needs to cooperate with a crane and needs to be fixed in four directions before use. Due to the large size and large mass of the precast concrete block, it is laborious to move, stack, and install, which may lead to difficult control of the direction during the hoisting process, easy to cause operation accidents, and reduce work efficiency.
