[0016] S2: The device is moved to the top of the vertically placed PC component by a tower crane, thereby reducing the height of the device so that the PC component can be inserted into the inside of the device. The steel wire rope is driven through the pre-made hole on the surface of the PC component by the connecting hook and is fastened inside the fixing hook. Then the steel wire rope is tightened by the rotating motor.

[0017] S3: Observe the feedback screens of Monitor 1 and Monitor 2 displayed on the industrial control computer, and then control the hydraulic rod to extend synchronously, so that the connecting rod drives the positioning plate to fit the PC component;

[0018] S4: The tower crane moves the PC component above the installation position using the device, and the construction workers make minor adjustments to the position of the device by pulling the pull plate;

[0019] S5: The industrial control computer controls the rotary motor to work, which drives the nut seat to descend through the double threaded screw, so that the PC component descends slowly. At the same time, the industrial control computer monitors the hydraulic rod to adjust the posture of the PC component so that it is aligned with the installation position.

[0020] S6: After the PC component reaches the installation position, loosen the wire rope, remove the connecting hook, and the hoisting of one PC component is completed.

[0021] The technical effects and advantages of this invention are as follows:

[0022] 1. This invention, by setting up a positioning mechanism and a traction mechanism, involves winding one end of the tower crane rope around and passing it through suspension rod one, then tying it to suspension rod two. The other end of the tower crane rope is then installed on the tower crane hook. The tower crane moves the device to the top of the vertically placed PC component, thereby lowering the device's height so that the PC component can be inserted into the device. The connecting hook drives the wire rope through the pre-drilled hole on the surface of the PC component and fastens it inside the fixing hook. The rotating motor two then tightens the wire rope. The feedback screens of monitor one and monitor two on the industrial control computer are observed, and the hydraulic rod is controlled to extend synchronously, causing the connecting rod to drive the positioning plate to fit against the PC component.

[0023] 2. The tower crane moves the PC component to the installation position using the device. Construction personnel fine-tune the position of the device by pulling the traction plate. The industrial control computer controls the rotating motor to work, which drives the nut seat to descend through the double threaded screw, causing the PC component to slowly descend. At the same time, the hydraulic rod is independently controlled to work and adjust the posture of the PC component through the monitoring screen displayed on the industrial control computer, so that it is aligned with the installation position. After the PC component reaches the installation position, the wire rope is released and the connecting hook is removed, completing the hoisting of one PC component. This provides an accurate hoisting device to help construction personnel quickly adjust the PC component at the installation position. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This invention discloses a precise positioning device for hoisting, such as... Figure 1-6 As shown, the device includes a body 1 and a positioning mechanism 3. Traction grooves 11 are provided at the four corners of the body 1. A lifting chamber 12 is provided on the inner wall of the body 1. A motor chamber 13 is provided below the lifting chamber 12. Adjustment chambers 14 are provided on both sides of the motor chamber 13. A suspension rod 15 is provided on the protruding surface of the body 1. A suspension rod 2 16 is provided on the outer side of the protruding surface. A traction mechanism 2 is installed on the inner side of the traction grooves 11. A positioning mechanism 3 is installed on the inner side of the body 1.

[0034] The positioning mechanism 3 includes a monitor 31, a lifting assembly 32, a connecting frame 33, a fixed seat 34, a rotating shaft 35, an annular seat 36, a fixing assembly 37, and an adjusting assembly 38. The monitor 31 is screwed to the bottom of the body 1. The lifting assembly 32 is installed inside the lifting chamber 12. The connecting frame 33 is installed inside the lifting assembly 32. The fixed seat 34 is welded to the bottom of the connecting frame 33. The bottom of the fixed seat 34 is rotatably connected to the annular seat 36 through the rotating shaft 35. The fixing assembly 37 is installed inside the annular seat 36. The adjusting assembly 38 is installed inside the adjusting chamber 14. The PC component is inserted into the device and then fixed to the inside of the annular seat 36 by the fixing assembly 37. When the PC component moves to the installation position, the lifting assembly 32 slowly lowers the PC component to the installation position. During the lowering process, the adjusting assembly 38 maintains the posture of the PC component. Thus, the position of the PC component can be quickly adjusted to avoid accidents to construction personnel.

[0035] Example 2

[0036] Based on Example 1, such as Figure 3 and Figure 4As shown, the lifting assembly 32 includes a rotary motor 321, a drive gear 322, a driven gear 323, a double-threaded screw 324, and a nut seat 325. The rotary motor 321 is screwed into the motor housing 13. The output shaft of the rotary motor 321 passes through the inner wall of the motor housing 13 and is fitted with the drive gear 322. The top of the drive gear 322 meshes with the driven gear 323. The double-threaded screw 324 passes through the interior of the driven gear 323. The nut seat 325 is threaded onto the outer side of the double-threaded screw 324. The nut seat 325 is welded to the connecting frame 33. The double-threaded screw 324 is rotatably connected to the lifting chamber 12 through a bearing. The installation height of the nut seats 325 is consistent. The lifting assembly 32 is symmetrically arranged along the central axis inside the body 1, ensuring that the nut seats 325 are on the same horizontal line. At the same time, the consistent installation height avoids the two ends of the connecting frame 33 from tilting, which would cause the device to wear out quickly.

[0037] Example 3

[0038] Based on Example 1, such as Figure 4 and Figure 5 As shown, an installation compartment 361 is provided on one side of the inner wall of the annular seat 36, and a fixing port 362 is provided on the other side of the inner wall of the annular seat 36. A second monitor 363 is screwed to both sides of the annular seat 36. The second monitor 363 is symmetrically arranged on both sides of the annular seat 36, which serves to feed back the top posture of the PC component to the industrial control computer 24. The installation compartment 361 and the fixing port 362 are staggered on both sides of the annular seat 36, so that the moving PC component remains balanced.

[0039] Example 4

[0040] Based on Example 1, such as Figure 2 and Figure 5 As shown, the fixing component 37 includes a second rotary motor 371, a drum 372, a wire rope 373, a connecting hook 374, and a fixing hook 375. The second rotary motor 371 is installed inside the installation chamber 361. The output shaft of the second rotary motor 371 is keyed to the drum 372. The wire rope 373 is fixedly connected to the surface of the drum 372. A connecting hook 374 is installed at one end of the wire rope 373. A fixing hook 375 is installed on the surface of the fixing port 362. The output shaft of the second rotary motor 371 is rotatably connected to the inner wall of the installation chamber 361 through a bearing. The fixing component 37 is symmetrically arranged about the central axis of the annular seat 36. The connecting hook 374 at one end of the wire rope 373 passes through the reserved hole of the PC component and connects with the fixing hook 375. Then, the second rotary motor 371 drives the drum 372 to rotate, tightening the wire rope 373 and fixing the PC component.

[0041] Example 5

[0042] Based on Example 1, such as Figure 3 , Figure 4 and Figure 6 As shown, the adjustment assembly 38 includes a first fixing block 381, a connecting seat 382, ​​a connecting rod 383, a positioning plate 384, an auxiliary seat 385, a connecting cap 386, a hydraulic rod 387, and a second fixing block 388.

The fixing block 388 is welded to the rear end of the inner wall of the regulating chamber 14. The hydraulic rods 387 are electrically connected to the industrial control computer 24. When fixing the PC component, the hydraulic rods 387 extend synchronously. Through the connecting rod 383, the positioning plate 384 is made to fit tightly against the surface of the PC component, preventing the PC component from moving around in the air. During installation, the construction personnel control the hydraulic rods 387 on both sides according to the monitoring screen to adjust the tilt angle of the PC component so that the PC component can be better placed in the installation position.

[0043] Furthermore, the surface of the positioning plate 384 is uniformly provided with rotating grooves 3841, and a pulley 3842 is installed inside the rotating groove 3841. The pulley 3842 is provided to prevent the PC component from rubbing against the positioning plate 384 when it moves downward, thus avoiding wear on the positioning plate 384 or the PC component.
