[0031] Please refer to Figures 1 to 5 The embodiment of the utility model provides a prefabricated component hoisting positioning precision control device, including front and back positioning assembly and left and right positioning assembly, front and back positioning assembly for positioning the front and back of the prefabricated component to be fixed includes positioning plate 1 and push plate 204, the top of positioning plate 1 is fixedly welded with arc plate 101 with guiding effect, positioning plate 1 is fixedly installed on the outside of lower layer fixed prefabricated wallboard 4 through expansion bolt, push plate 204 is installed on prefabricated floor 5 in the front and back direction position adjustable through first adjusting part 2, left and right positioning assembly is provided with two groups for positioning the left and right of the prefabricated component to be fixed, two groups of left and right positioning assembly are installed on the top of prefabricated floor 5 respectively on both sides, and two groups of left and right positioning assembly all include pull plate 304 and second adjusting part 3, pull plate 304 is installed on prefabricated floor 5 in the left and right direction position adjustable through second adjusting part 3.

[0032] Among them, positioning plate 1 is fixed on the outside of lower layer fixed prefabricated wallboard 4 and is used as the reference of front and back positioning.Push plate 204 can be adjusted in the front and back direction through first adjusting part 2, cooperates with positioning plate 1, realizes the positioning of prefabricated component to be fixed in the front and back direction.Two groups of left and right positioning assembly are arranged on the top of prefabricated floor 5 on both sides, and pull plate 304 is adjusted in the left and right direction through second adjusting part 3, so that the left and right sides of prefabricated component are positioned.

[0033] In the embodiment, the first adjusting member 2 comprises a first support base 201, the upper end of the first support base 201 is slidingly inserted with a first rack 202, a push plate 204 is fixedly installed at one end of the first rack 202, the top of the first adjusting member 2 is fixedly connected with a first fixed block 205, the first fixed block 205 is slidingly inserted with a first movable rod 206, the top of the first movable rod 206 is fixedly connected with a first handle 207, the bottom of the first movable rod 206 is fixedly connected with a first limiting clamping tooth 209, one side of the first limiting clamping tooth 209 is provided with a first guide inclined surface, the first limiting clamping tooth 209 can be clamped on the first rack 202, one side of the push plate 204 is fixedly connected with a first guide rod 203, the end of the first guide rod 203 away from the push plate 204 is slidingly penetrated through the first support base 201, the first guide inclined surface is arranged to make the push plate 204 be smoothly pushed in the direction of the positioning plate 1, but when the push plate 204 moves away from the positioning plate 1, the vertical surface of the first limiting clamping tooth 209 can limit the first rack 202.

[0034] When the push plate 204 is pushed to move in the direction of the positioning plate 1, the first rack 202 slides on the first support base 201, the guide inclined surface of the first limiting clamping tooth 209 makes it can slide on the first rack 202 without hindering the pushing. When it is needed to fix the position of the push plate 204, if the push plate 204 has a tendency to move away from the positioning plate 1, the vertical surface of the first limiting clamping tooth 209 can be clamped on the first rack 202 to prevent it from moving, thereby achieving positioning. The first guide rod 203 ensures the linearity of the movement of the push plate 204.

[0035] Further, the end of the first guide rod 203 away from the push plate 204 is fixedly connected with a first handle 210, the end of the first rack 202 away from the push plate 204 is fixedly connected with the first handle 210.

[0036] By operating the first handle 210, the first guide rod 203 and the first rack 202 can be more conveniently pushed, thereby driving the push plate 204 to move, and the convenience of operation is improved.

[0037] Further, the first movable rod 206 is sleeved with a first spring 208, the bottom of the first spring 208 is pressed on the top of the first limiting clamping tooth 209, and the top of the first spring 208 is abutted against the bottom of the first fixed block 205.

[0038] The first spring 208 always exerts downward pressure on the first limiting clamping tooth 209 to ensure that the first limiting clamping tooth 209 is in close contact with the first rack 202, thereby enhancing the limiting effect and preventing the first limiting clamping tooth 209 from accidentally disengaging from the first rack 202.

[0039] In this embodiment, the second adjusting member 3 includes a second support base 301. A second rack 302 is slidably inserted into the upper end of the second support base 301. A pull plate 304 is fixedly installed on one end of the second rack 302. A second guide rod 303 is fixedly connected to one side of the pull plate 304. The end of the second guide rod 303 away from the pull plate 304 slides through the second support base 301. A second fixing block 305 is fixedly connected to the top of the second support base 301. A second movable rod 306 is slidably inserted into the second fixing block 305. The top of the second rod is fixedly connected to a second handle 307, and the bottom of the second movable rod 306 is fixedly connected to a second limiting tooth 309. A second guide slope is provided on one side of the second limiting tooth 309. The second limiting tooth 309 can be locked on the second rack 302. Through the second guide slope, the pull plate 304 can be pulled smoothly when it is pulled closer to the precast floor slab 5. However, when the pull plate 304 moves away from the precast floor slab 5, the vertical surface of the second limiting tooth 309 will limit the second rack 302.

[0040] Similar to the first adjusting member 2, when the pulling plate 304 is moved closer to the precast floor slab 5, the second rack 302 slides on the second support base 301, and the second guide slope of the second limiting tooth 309 does not obstruct the pulling. When the pulling plate 304 tends to move away from the precast floor slab 5, the vertical surface of the second limiting tooth 309 will engage with the second rack 302 to achieve positioning. The second guide rod 303 ensures the straightness of the movement of the pulling plate 304.

[0041] Furthermore, a second spring 308 is sleeved on the second movable rod 306. The upper end of the second spring 308 abuts against the bottom of the second fixed block 305, and the lower end of the second spring 308 presses against the top of the second limiting tooth 309.

[0042] The second spring 308 applies downward pressure to the second limiting tooth 309 to ensure that the second limiting tooth 309 is in close contact with the second rack 302, thereby enhancing the limiting effect and preventing the second limiting tooth 309 from accidentally disengaging from the second rack 302.

[0043] Furthermore, the second guide rod 303 is fixedly connected to the second handle 310 at the end away from the pull plate 304, and the second rack 302 is fixedly connected to the second handle 310 at the end away from the pull plate 304.

[0044] By operating the second handle 310, the second guide rod 303 and the second rack 302 can be pulled more easily, thereby driving the pull plate 304 to move and improving the ease of operation.

[0045] Assembly holes 321 are provided at the bottom of the first support 201 and the bottom of the second support 301.

[0046] The assembly hole 321 is used to fix the first support 201 and the second support 301 onto the precast floor slab 5 to ensure the stability of the entire positioning device.

[0047] A self-lubricating layer is provided between the sliding mating surfaces of the second support 301 and the second rack 302. The self-lubricating layer is a polytetrafluoroethylene coating with a thickness of 0.05-0.1mm to reduce sliding friction and facilitate the position adjustment of the pull plate 304 in the left and right directions.

[0048] In order to reduce the sliding friction between the first guide rod 203 and the first support 201 and the second guide rod 303 and the second support 301, the surface friction of the first guide rod 203 and the second guide rod 303 is set to be no greater than Ra0.2.

[0049] Operating steps:

[0050] Device installation:

[0051] Use expansion bolts to fix the positioning plate 1 to the outside of the lower precast wall panel 4.

[0052] Through the assembly hole 321, the first support 201 and the second support 301 are fixed to the corresponding positions on the precast floor slab 5 with expansion bolts.

[0053] Precast component hoisting: Use hoisting equipment to hoist the precast components to be fixed to the installation position above the installation position, and hoist them as high as possible to the position of the push plate 204, so that when the precast components to be fixed are lowered, they can fall between the positioning plate 1 and the push plate 204.

[0054] Front and rear positioning:

[0055] Hold the first handle 210 and push the push plate 204 toward the positioning plate 1, so that the push plate 204 and the positioning plate 1 position the precast component in the front and back directions. The first limiting tooth 209 automatically limits and fixes the position of the push plate 204.

[0056] Left and right positioning:

[0057] Hold the second handle 310 and pull the pull plate 304 towards the precast floor slab 5 so that the two sets of pull plates 304 position the left and right sides of the precast component. The second limit tooth 309 automatically limits and fixes the position of the pull plate 304.

[0058] Component fixing: After positioning is completed, the prefabricated components are fixedly connected to the lower prefabricated wall panels 4.
