Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to a building component lifting device. Background Art

[0002] In construction projects, steel cages are crucial components of pile foundations, and their installation quality directly impacts the bearing capacity and structural stability of the pile foundation. Currently, steel cages are typically installed using double-hook lifting equipment. This involves securing the cages with two sets of hooks, hoisting them to the pile hole using a crane, and flipping them mid-air, adjusting them from a horizontal to a vertical position before lowering them into the hole. However, this traditional lifting method suffers from numerous technical drawbacks in practical applications, severely limiting construction efficiency and safety.

[0003] First, since the steel cage itself has a long longitudinal dimension and a large deadweight, it is often difficult to achieve a reasonable distribution of force points when using double hooks for lifting, resulting in uneven force on the steel cage during the lifting process, which is prone to bending and deformation, affecting its structural integrity. Secondly, the technical threshold for the coordinated operation of double hooks is relatively high, and it is necessary to accurately control the lifting speed and force distribution of the two sets of hoists. During construction, the steel cage often deflects unexpectedly due to asynchronous operations, which not only prolongs the adjustment time, but is also likely to cause lifting accidents. In addition, in the early stage of flipping, the steel cage is usually lifted first at one end and is in a tilted state. At this time, the other end is still in contact with the ground. As the lifting action continues, a large extrusion pressure will be generated between the end of the steel cage and the ground, which can easily cause local deformation of the end of the steel cage, further affecting its overall structural performance and construction quality. Summary of the Invention

[0004] In view of this, the present invention provides a building component lifting device, which can overcome the shortcomings of the existing steel cage, which is easily bent and deformed due to uneven force during the lifting process, and the mutual compression between the ends of the steel cage and the ground, which easily causes local deformation. In addition, the technical threshold for the coordinated operation of the double hooks is high, the operation is difficult, and it affects the installation efficiency.

[0027] like Figure 1 and Figure 6 As shown, the protective assembly includes a fixing frame 17, a second insertion rod 18, a first wheel 19 and a second wheel 20. A fixing frame 17 is provided on the right side of the second steel pipe frame 2, and three second insertion rods 18 are connected to the upper left side of the fixing frame 17 at intervals. The second insertion rods 18 can also be inserted into the insertion hole 8, thereby completing the docking work between the second steel pipe frame 2 and the fixing frame 17. The lower part of the fixing frame 17 is symmetrically connected to the first wheel 19 in front and back rotation, and the upper part of the fixing frame 17 is rotatably connected to the second wheel 20.

[0028] like Figure 6 and Figure 7 As shown, it also includes a connecting frame 21, a third electric push rod 22, a guide frame 23 and a sliding tube 24. The lower part of the connecting frame 21 is symmetrically connected to the connecting frame 21 in the front and back, and the third electric push rod 22 is installed on the two connecting frames 21. The lower part of the connecting frame 21 is symmetrically connected to the guide frame 23 in the front and back. The guide frame 23 is located on the right side of the connecting frame 21.

The telescopic rod of the third electric push rod 22 is connected to the inner wall of the sliding tube 24.

[0029] like Figure 1 and Figure 8As shown, it also includes a line laser 25 and a locking mechanism. The two curved plates 5 on the left are each equipped with a line laser 25. The fixing frame 17 is provided with a locking mechanism for locking the first wheel 19. The locking mechanism includes a fourth electric push rod 26 and a brake pad 27. The fourth electric push rod 26 is installed on the lower part of the front and rear sides of the fixing frame 17. The brake pad 27 is connected to the telescopic rod of the two fourth electric push rods 26. The brake pad 27 is located directly above the first wheel 19.

[0030] In the initial state, the fixing frame 17 is in a horizontal state, and the first wheel 19 and the second wheel 20 are in contact with the ground, which can keep the fixing frame 17 stable. When the steel cage needs to be installed, the appropriate number of second steel pipe frames 2 can be selected according to the length of the steel cage. Then, the workers will dock the first steel pipe frame 1 and the second steel pipe frame 2 horizontally on the ground so that the first insertion rods 7 can be inserted into the adjacent insertion holes 8. Then, the corresponding first fastening bolts 9 are tightened to complete the docking work of the first steel pipe frame 1 and the second steel pipe frame 2. Then, the crane By hooking the hook to the rotating hook 12, the first steel pipe rack 1 and the second steel pipe rack 2 can be lifted into the air by the crane, so that the first steel pipe rack 1 and the second steel pipe rack 2 are in a vertical state, and the first steel pipe rack 1 and the second steel pipe rack 2 are moved to the top of the fixing frame 17. Then, the first steel pipe rack 1 and the second steel pipe rack 2 are controlled to move downward. The worker assists in inserting the second insertion rod 18 into the insertion hole 8 on the second steel pipe rack 2 on the lowermost side, and then tightens the first fastening bolt 9 on the second steel pipe rack 2 on the lowermost side. The docking work between the second steel pipe rack 2 and the fixing frame 17 can be completed.Then the first steel pipe frame 1, the second steel pipe frame 2 and the fixed frame 17 can be lifted into the air by a crane and moved to the upper right side of the steel cage. At this time, the straight line laser 25 can be controlled to emit a straight line laser to irradiate the ground. At the same time, the reduction motor 101 is controlled to start working. Since the rotating hook 12 is hung on the hook of the crane, the rotating hook 12 does not rotate. At this time, the reduction motor 101 will rotate, driving the sliding frame 10, the first steel pipe frame 1, the second steel pipe frame 2 and the fixed frame 17 to rotate, so that the direction of the first steel pipe frame 1, the second steel pipe frame 2 and the fixed frame 17 can be adjusted. When the straight line lasers emitted by the two straight line lasers 25 are irradiated on the front and back sides of the steel cage respectively, That is, the first steel pipe frame 1, the second steel pipe frame 2 and the fixing frame 17 are in the same vertical plane as the steel cage, and then the fixing frame 17 can be stably placed on the right end of the steel cage, and then the fourth electric push rod 26 is controlled to drive the brake pad 27 to move in the direction close to the first wheel 19 until the brake pad 27 contacts the surface of the first wheel 19. The friction between the brake pad 27 and the first wheel 19 can prevent the first wheel 19 from rotating, so that the first wheel 19 can be locked. At this time, the crane pulls the rotating hook 12 to the left, which can make the first steel pipe frame 1, the second steel pipe frame 2 and the fixing frame 17 rotate downward with the first wheel 19 as the rotation center, until the first steel pipe frame 1 and the second The steel pipe frame 2 rotates to the top of the steel cage. At this time, the sliding frame 10 is located at the left end of the steel cage. Then the fourth electric push rod 26 is controlled to drive the brake pad 27 to move back in the direction away from the first wheel 19, so that the brake pad 27 is disengaged from the first wheel 19. Then the first electric push rod 4 is controlled to drive the curved plate 5 to rotate and close, so that the curved plate 5 can be surrounded by the outside of the steel cage. Then the sliding frame 10 is pushed to the right. The sliding frame 10 can drive the sliding hook 13 to move to the right and enter the inside of the steel cage. Then the second electric push rod 15 is controlled to drive the four sliding hooks 13 to move to the side away from each other, so that the four sliding hooks 13 all pass through the outside of the steel cage. Then the crane is used to pull the rotating hook 12 to move upward. The movable frame 10 will first slide to the left on the first steel pipe frame 1 and reset when it is subjected to force. The sliding frame 10 will drive the sliding hook 13 to move to the left and hook the steel cage. Then the sliding frame 10 can move upward with the rotating hook 12, and the sliding frame 10 can lift the left end of the steel cage through the sliding hook 13, so that the steel cage can be flipped upward with the first wheel 19 as the rotation center. This can prevent the right end of the steel cage from being squeezed against the ground and causing deformation. During the flipping process, the curved plate 5 can limit the steel cage to prevent the steel cage from bending and deforming. At the same time, the first steel pipe frame 1, the second steel pipe frame 2 and the fixed frame 17 will also rotate upward and reset with the first wheel 19 as the rotation center until the steel cage is flipped to a vertical state (such as; Figure 2As shown); then the rotating hook 12 and the sliding frame 10 are lifted by a crane, and the sliding frame 10 can lift the steel cage into the air through the sliding hook 13, and then the steel cage is controlled to move above the installation hole, and then the third electric push rod 22 is controlled to drive the sliding tube 24 to move downward and extend, so that the two sliding tubes 24 are V-shaped, and then the rotating hook 12 and the sliding frame 10 are controlled by the crane to move downward, and the sliding frame 10 can lower the steel cage through the sliding hook 13, so that the sliding tube 24 can be inserted into the installation hole. The sliding tube 24 plays a positioning role, so that the steel cage can be vertically aligned with the installation hole. At this time The fixing frame 17 will be located on the ground outside the installation hole, and then the first electric push rod 4 will be controlled to drive the curved plate 5 to reverse and open, so that the curved plate 5 is separated from the steel cage, and then the third electric push rod 22 will be controlled to drive the sliding tube 24 to move upward and retract, and then the crane will control the rotating hook 12 and the sliding frame 10 to continue to move downward, and the sliding frame 10 can continue to lower the steel cage through the sliding hook 13, so that the steel cage can smoothly enter the installation hole. At this time, the sliding frame 10 will move downward along the first steel pipe frame 1 and the second steel pipe frame 2, so as not to affect the lowering of the steel cage. When the steel cage is installed, The crane controls the rotating hook 12 and the sliding frame 10 to continue to move downward, and the sliding frame 10 drives the sliding hook 13 to move downward and separate from the steel cage, and then controls the second electric push rod 15 to drive the four sliding hooks 13 to move toward the side close to each other, so that the sliding hook 13 is completely retracted into the inner side of the steel cage, and then controls the rotating hook 12 and the sliding frame 10 to move upward by the crane, so that the sliding frame 10 can move upward and reset along the first steel pipe frame 1 and the second steel pipe frame 2, and the sliding frame 10 can drive the sliding hook 13 to move upward and away from the steel cage, and then the first steel pipe frame 1 is lifted by the crane. , the second steel pipe rack 2 and the fixed frame 17 are lifted to the right end of the next steel cage, and the above operations can be repeated to lift and install the next steel cage without further splicing work; when it is necessary to adapt to steel cages of different diameters, the second fastening bolts 16 can be loosened first, and then the position of the sliding sleeve 14 can be moved. The sliding sleeve 14 can drive the second electric push rod 15 and the sliding hook 13 to move synchronously to adjust the initial position of the sliding hook 13 to ensure that the four sliding hooks 13 can fully enter the inner side of the steel cage. After adjustment, tighten the second fastening bolts 16 to fix the position of the sliding hook 13.
