[0020] A method for guiding the hoisting and positioning device of an assembled building wall, comprising the following steps:

[0021] Step 1: Lift the second prefabricated wall panel using a lifting device, and then screw the trumpet guide bucket to the bottom of the positioning hole;

[0022] Step 2: Hang the second prefabricated wall panel at a specified height on the first prefabricated wall panel;

[0023] Step 3: The driving mechanisms on both sides respectively drive the first positioning plates to move inward, so that the first positioning plates on both sides are respectively in contact with the surface of the first prefabricated wall panel, and the first positioning plates synchronously drive the second positioning plates to be in contact with the surface of the second prefabricated wall panel;

[0024] Step 4: The third positioning plate is driven by the adjustment mechanism to move toward the first prefabricated wall panel so that the third positioning plate is in contact with the first prefabricated wall panel.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figure 1-Figure 2 As shown, the present invention is a guiding hoisting and positioning device for prefabricated building walls, comprising first positioning plates 305 arranged on both sides of a first prefabricated wall panel 1, and second positioning plates 503 arranged on both sides of a second prefabricated wall panel 2. In one embodiment of the present invention, the first positioning plates 305 and the second positioning plates 503 are arranged perpendicularly.

[0040] The first positioning plates 305 on both sides are connected to the driving mechanism arranged on the base 3; specifically, in this embodiment, the base 3 is first placed on one side of the first prefabricated wall panel 1, so that the first prefabricated wall panel 1 is located between the first positioning plates 305 on both sides, and then the second prefabricated wall panel 2 is hoisted to a specified height on the first prefabricated wall panel 1 by the hoisting equipment, and the driving mechanisms on both sides respectively drive the first positioning plates 305 to move inward so that the first positioning plates 305 on both sides are respectively fitted with the surface of the first prefabricated wall panel 1. At the same time, the first positioning plates 305 synchronously drive the second positioning plates 503 to fit the surface of the second prefabricated wall panel 2. At this time, the first prefabricated wall panel 1 and the second prefabricated wall panel 2 are in a corresponding state; in this embodiment, the second positioning plates 503 have a certain length, so that even if the second prefabricated wall panel 2 and the first prefabricated wall panel 1 are at a long distance, it is still possible to judge whether the second prefabricated wall panel 2 corresponds to the first prefabricated wall panel 1, and the assembly accuracy is higher;

[0041] The base 3 is also provided with a third positioning plate 502 for positioning the side of the first prefabricated wall panel 1 and a fourth positioning plate 501 for positioning the side of the second prefabricated wall panel 2. The third positioning plate 502 and the fourth positioning plate 501 are arranged on both sides of the limit plate 5 relative to each other, and the third positioning plate 502 is connected to the adjustment mechanism arranged on the base 3; it can be explained that during positioning, the third positioning plate 502 is driven by the adjustment mechanism to move toward the direction of the first prefabricated wall panel 1, so that the third positioning plate 502 is in contact with the first prefabricated wall panel 1. At the same time, the third positioning plate 502 drives the fourth positioning plate 501 to be in contact with the side of the second prefabricated wall panel 2 through the limit plate 5, thereby further judging whether the first prefabricated wall panel 1 and the second prefabricated wall panel 2 correspond to each other.

[0042] Example 2

[0043] Based on Example 1, please refer to Figure 3-Figure 4 , a guide groove 301 is relatively opened on the base 3, and a guide seat 302 is slidably arranged in the guide groove 301, wherein the first positioning plate 305 is fixedly connected to the guide seat 302 through an L-shaped support rod 304;

[0044] As a further solution of this embodiment, the driving mechanism includes a first support 303 arranged on the base 3, a first screw 401 rotatably arranged in the first support 303, and a driving motor 4 connected to the end of the first screw 401, wherein a nut 306 fixedly connected to the L-shaped support rod 304 is spirally sleeved on the first screw 401; it should be noted that the driving motor 4 drives the first screw 401 to rotate, and the nut 306 drives the first positioning plate 305 to move via the L-shaped support rod 304 during the process of moving on the first screw 401 to adjust its position;

[0045] The adjustment mechanism includes a second support 307 disposed on the base 3. A second screw 601 is spirally disposed in the second support 307. One end of the second screw 601 is rotatably connected to the third positioning plate 502, and the other end is provided with a handle 6. It can be explained that when adjusting the positions of the third positioning plate 502 and the fourth positioning plate 501, rotating the handle 6 drives the second screw 601 to rotate, and the second screw 601 drives the third positioning plate 502 to move.

[0046] See also Figure 5 , a plurality of groups of steel bars 101 are arranged in the first prefabricated wall panel 1, wherein a plurality of groups of positioning holes are correspondingly arranged in the second prefabricated wall panel 2; it can be explained that when the first prefabricated wall panel 1 and the second prefabricated wall panel 2 are assembled, the steel bars 101 on the first prefabricated wall panel 1 are plugged into the positioning holes on the second prefabricated wall panel 2 in a one-to-one correspondence;

[0047] Furthermore, a trumpet guide 202 is provided at the bottom of the positioning hole, and a threaded end 204 is provided on the trumpet guide 202, which is spirally connected to the positioning hole. A reserved groove 203 is provided between the trumpet guide 202 and the threaded end 204. It can be explained that before the first prefabricated wall panel 1 is connected to the second prefabricated wall panel 2, the trumpet guide 202 is first screwed and installed at the positioning hole. By arranging the trumpet guide 202, the connection between the steel bar 101 and the positioning hole is more accurate, and a guiding effect is achieved.

[0048] In addition, after the steel bar 101 is positioned with the positioning hole, the horn guide bucket 202 is screwed out of the positioning hole, and the horn guide bucket 202 is removed from the steel bar 101 through the reserved groove 203. After the horn guide bucket 202 is removed, the second prefabricated wall panel 2 is continued to be hoisted toward the direction of the first prefabricated wall panel 1 until the bottom end of the second prefabricated wall panel 2 coincides with the upper end face of the first prefabricated wall panel 1.

[0049] The second prefabricated wall panel 2 is hung with a rope 201, and the rope 201 is provided with a hanging ring 207 for hooking with a lifting device; specifically, the second prefabricated wall panel 2 is lifted by hooking the hanging ring 207 with the hook of the lifting device;

[0050] The second positioning plates 503 on both sides are provided with a plurality of grooves 205, in which guide wheels 206 are rotatably arranged. It can be explained that when the second positioning plates 503 on both sides are moved inward, the guide wheels 206 contact the second positioning plates 503, so that when the lifting equipment is lifting the second prefabricated wall panel 2 toward the first prefabricated wall panel 1, excessive friction that affects the movement of the second prefabricated wall panel 2 is avoided.

[0054] Step 2: Hang the second prefabricated wall panel 2 at a specified height on the first prefabricated wall panel 1;

[0055] Step 3: The driving mechanisms on both sides respectively drive the first positioning plates 305 to move inward, so that the first positioning plates 305 on both sides are respectively attached to the surface of the first prefabricated wall panel 1. The first positioning plates 305 simultaneously drive the second positioning plates 503 to attach to the surface of the second prefabricated wall panel 2.

[0056] Step 4: The third positioning plate 502 is driven by the adjustment mechanism to move toward the first prefabricated wall panel 1 so that the third positioning plate 502 is in contact with the first prefabricated wall panel 1. The third positioning plate 502 passes through the limit plate 5 to drive the fourth positioning plate 501 to be in contact with the side of the second prefabricated wall panel 2.

[0057] Step 5: After the steel bar 101 is positioned with the positioning hole, the horn guide bucket 202 is twisted out of the positioning hole and the horn guide bucket 202 is removed from the steel bar 101 through the reserved groove 203;

[0058] Step 6: Continue to hoist the second prefabricated wall panel 2 toward the first prefabricated wall panel 1 until the bottom end of the second prefabricated wall panel 2 coincides with the upper end surface of the first prefabricated wall panel 1 .
