Description

Technical Field

[0001] The present invention relates to the technical field of hoisting in building construction, and specifically relates to a rapid hoisting device for prefabricated components and its usage method. Background Art

[0002] In modern building construction, prefabricated buildings are widely used due to their advantages such as fast construction speed, easy quality control, and little environmental impact. The core of prefabricated buildings lies in the production and on-site hoisting of precast components. In coastal areas, due to special environmental conditions such as strong winds and high humidity, higher requirements are put forward for the hoisting accuracy and speed of prefabricated components.

[0003] Currently, traditional methods for hoisting prefabricated components mainly rely on the experience and skills of crane operators. During the hoisting process, the crane first lifts the precast component from the ground or a transport vehicle and then slowly lowers it to the predetermined position. When approaching the ground, manual assistance is required to straighten the component to ensure its accurate positioning. This process not only takes time but also requires high skills from the operators, and it is easy to cause damage to the component or construction accidents due to improper operation.

[0004] For example, when hoisting a precast beam, the traditional method requires close cooperation between the crane operator and the ground assistants. The operator controls the lifting and movement of the lifting rope on the crane, while the ground assistants guide the operator to make fine adjustments through shouting or gestures. Due to the influence of wind in coastal areas, the component may swing in the air, resulting in difficult positioning. In addition, during the manual straightening process, it is difficult to ensure the precise alignment of the component due to the limitations of sight and operating space, and sometimes multiple attempts are even required to succeed. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid hoisting device for prefabricated components and its usage method, which can automatically fine-tune the angle and position of the precast component after the crane lowers the precast component close to the ground, thereby reducing manual intervention and improving hoisting efficiency and accuracy, especially suitable for construction under special environmental conditions such as coastal areas.

[0011] The linkage mechanism includes a worm fixed at the output end of the first motor. A worm gear is meshed and connected to the outside of the worm, and the worm gear is connected to the transmission column.

[0012] On one side of the driving roller away from the driving column, a connecting frame is fixed. At the central position inside the connecting frame, an installation round block is arranged. The installation round block is connected to the frame through a support member. Inside the installation round block, a plurality of guiding square columns are slidably connected. One end of the guiding square column away from the installation round block is fixed with a braking block. At a position of the braking block close to the inner wall of the connecting frame, a plurality of clamping blocks are arranged. On the inner wall of the connecting frame, clamping grooves corresponding to the clamping blocks are arranged;

Detailed implementation mode

[0038] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention. Embodiment 1

[0039] Refer to the attached Figure 1-12 , a quick hoisting device for prefabricated components, including a frame 1 and a prefabricated component body 2. The frame 1 is integrally arranged in an inverted U shape, and the bottoms of both ends of the frame 1 are lower than the width of the prefabricated component body 2, so as to ensure that when the first pushing plate 13 and the second pushing plate 19 perform fine adjustment on the prefabricated component body 2 later, there will be no resistance due to the contact between the prefabricated component body 2 and the ground. And the prefabricated component body 2 is arranged inside the frame 1. A first motor 5 is installed on the top of the prefabricated component body 2. A linkage mechanism is installed at the output end of the first motor 5, and a transmission column 6 is installed at the end of the linkage mechanism far from the first motor 5;

[0040] Refer to the attached Figure 4 , the linkage mechanism includes a worm 9 fixed to the output end of the first motor 5. The outside of the worm 9 is meshed with a worm gear 10, and the worm gear 10 is connected to the transmission column 6;

[0041] When the first motor 5 is driven, it can drive the worm 9 to rotate, and through the meshing connection between the worm 9 and the worm gear 10, the worm 9 can drive the worm gear 10 to rotate, and drive the transmission column 6 to rotate through the worm gear 10. Through the setting of the worm 9 and the worm gear 10, the worm 9 can drive the worm gear 10 to rotate, while the worm gear 10 cannot drive the worm 9 to rotate, avoiding sudden falling due to the excessive weight of the prefabricated component body 2, and playing a certain limiting role;

[0042] A support frame 37 is rotatably connected to the outer side of the transmission column 6. The support frame 37 is fixedly connected to the frame 1. A transmission roller 7 is fixed to one end of the transmission column 6 away from the linkage mechanism. A connecting rope 8 is wound around the outer side of the transmission roller 7. The connecting rope 8 passes through the frame 1 and is fixed with a plurality of hanging ropes 4. Hooks 3 are installed at the four end corners of the top of the precast member body 2. And a plurality of the hooks 3 are respectively connected to each other. Through the connection between the hanging ropes 4 and the hooks 3, the precast member body 2 can be hoisted inside the frame 1. And the hanging ropes 4 are arranged in a cross shape. Thus, when hoisting the precast member body 2, the rotation amplitude of the precast member body 2 is reduced;

[0043] When it is necessary to lower the precast member body 2, the first motor 5 can be driven so that the output end of the first motor 5 drives the linkage mechanism, and the transmission column 6 is driven to rotate through the linkage mechanism. Then the transmission roller 7 is driven to rotate by the transmission column 6. Through the connecting rope 8 wound around the outer side of the transmission roller 7, the connecting rope 8 gradually disengages from the winding of the transmission roller 7, and the hanging rope 4 is lowered. Then the precast member body 2 is lowered through the hanging rope 4;

[0044] Refer to the appendix Figure 8 Referring to the appendix, installation grooves 22 are provided inside both ends of the bottom of the frame 1. A sliding column 23 is slidably connected inside the installation groove 22 and near the bottom end. A first spring 24 is installed between the top of the sliding column 23 and the inner wall of the installation groove 22. A contact piece 25 is fixed to the bottom of the sliding column 23;

[0045] When the frame 1 contacts the ground, first, the contact piece 25 contacts the ground. And due to the arrangement of the first spring 24, when the contact piece 25 contacts the ground, there will be a certain buffering effect first, avoiding the precast member body 2 from detaching from the frame 1 or the precast member body 2 from shaking too much suddenly due to the sudden excessive vibration of the frame 1;

[0046] Refer to the appendix Figure 5 Referring to the appendix, a pushing mechanism is also installed on the frame 1. The pushing mechanism is used to push the precast member body 2 to move;

[0047] Refer to the appendix Figure 6 Referring to the appendix, the pushing mechanism includes two first threaded rods 11 rotatably connected inside both ends of the frame 1. And first socket rods 12 are threadedly connected to the outer sides of the mutually approaching ends of the two first threaded rods 11. A first pushing plate 13 is fixed to the end of the first socket rod 12 away from the first threaded rod 11. The first pushing plate 13 is arranged at the corresponding position of the precast member body 2. At least one first guiding rod 14 is also fixed to the side of the first pushing plate 13 close to the first threaded rod 11. And the first guiding rod 14 is slidably connected to the frame 1. A second motor 15 is installed on the outer side of the frame 1 at the corresponding position of the first threaded rod 11. And the output end of the second motor 15 is connected to the first threaded rod 11;

[0048] Refer to the appendix Figure 7 Moreover, the pushing mechanism further includes mounting plates 16 fixed at the four end corners of the precast member body 2 inside the frame 1. A second threaded rod 17 is rotatably connected inside the mounting plate 16. A second socket rod 18 is threadedly connected to the outer side of the second threaded rod 17 near one end of the precast member body 2. A second pushing plate 19 is fixed at the end of the second socket rod 18 away from the second threaded rod 17, and the second pushing plate 19 is arranged at the corresponding position of the precast member body 2. A second guiding rod 20 is further fixed on one side of the second pushing plate 19 close to the second threaded rod 17. The second guiding rod 20 is slidably connected to the mounting plate 16. A third motor 21 is further installed on the side of the mounting plate 16 away from the second pushing plate 19 and at the corresponding position of the second threaded rod 17. The output end of the third motor 21 is connected to the second threaded rod 17;

[0049] A plurality of balls 38 are installed on the sides of the first pushing plate 13 and the second pushing plate 19 close to the precast member body 2. Through the arrangement of the balls 38, when the hanging rope 4 lowers the precast member body 2, the friction between the balls 38 and the first pushing plate 13 and the second pushing plate 19 can be reduced. Furthermore, when the first pushing plate 13 or the second pushing plate 19 pushes the precast member body 2 to cause fine adjustment of the precast member body 2, the precast member body 2 can also be lowered;

[0050] An observation device such as a monitor or a camera and a controller can also be arranged on the frame 1. Then, the position and angle of the precast member body 2 are detected through the observation device. When fine adjustment is required, a signal can be transmitted to the controller through the observation device, and the third motor 21 or the second motor 15 is controlled to start through the controller;

[0051] Refer to the appendix Figure 9 Moreover, a connection frame 26 is fixed on the side of the transmission roller 7 away from the transmission column 6. An installation round block 27 is arranged at the central position inside the connection frame 26. The installation round block 27 is connected to the frame 1 through a support member. A plurality of guiding square columns 28 are slidably connected inside the installation round block 27. A braking block 29 is fixed at the end of the guiding square column 28 away from the installation round block 27. A plurality of clamping blocks 30 are arranged at the position of the braking block 29 close to the inner wall of the connection frame 26. A clamping groove 31 corresponding to the clamping block 30 is arranged on the inner wall of the connection frame 26. The clamping blocks 30 on the braking block 29 can be at multiple angles, and the clamping groove 31 adapts to the angles of the clamping blocks 30. Furthermore, when the clamping blocks 30 are inserted into the clamping groove 31, it can play a role in restricting the rotation of the connection frame 26 whether it rotates forward or backward;

[0052] A driving mechanism is installed inside the installation round block 27, and the driving mechanism is used to drive the guiding square column 28 to move towards the direction close to the connection frame 26;

[0053] When the driving mechanism is driving, the guiding square column 28 can be controlled to move towards the outside of the mounting circular block 27, thereby driving the brake block 29 and the clamping block 30 to move towards the direction close to the inner wall of the connecting frame 26, so that the brake block 29 is in mutual contact with the connecting frame 26. Furthermore, through the frictional force between the brake block 29 and the inner wall of the connecting frame 26, the connecting frame 26 can be restricted. Further, the clamping block 30 is inserted into the clamping groove 31 to restrict the rotation of the connecting frame 26. When the rotation of the connecting frame 26 is restricted, the worm wheel 10, the worm 9, etc. cannot rotate either;

[0054] Refer to the appendix Figure 10-11 , the driving mechanism includes an electromagnet 32 arranged inside the mounting circular block 27. One end of the guiding square column 28 close to the electromagnet 32 is also provided with a movable magnet 33, and the magnetic poles of the mutually close sides of the movable magnet 33 and the electromagnet 32 are the same. For example, if the side of the electromagnet 32 close to the movable magnet 33 is the S pole, then the side of the movable magnet 33 close to the electromagnet 32 is the N pole, and vice versa. Both upper and lower sides of the guiding square column 28 inside the mounting circular block 27 are provided with an assembly groove 34. Both upper and lower sides of the guiding square column 28 are fixed with sliding plates 35, and the sliding plates 35 extend into the assembly grooves 34. A second spring 36 is fixed between the sliding plates 35 and the inner walls of the assembly grooves 34;

[0055] When the electromagnet 32 is not activated, the guiding square column 28 is always arranged inside the mounting circular block 27 by the pulling force of the second spring 36, so that the clamping block 30 does not come into contact with the inner wall of the connecting frame 26. When the electromagnet 32 is activated, the movable magnet 33 can be repelled, and the movable magnet 33 drives the guiding square column 28 to move away from the electromagnet 32, stretching the second spring 36, so that the clamping block 30 comes into contact with the inner wall of the connecting frame 26 to brake the connecting frame 26; Embodiment 2

[0056] A usage method of a quick hoisting device for assembled components, which is used to explain how to use the above-mentioned quick hoisting device. The usage method includes the following steps:

[0057] When hoisting the precast component body 2 and wanting to move and hoist it to a suitable position, first hoist the frame 1 outside the precast component body 2 and connect it to the hook 3 at the top of the precast component body 2 through the hanging rope 4. Then drive the crane so that the crane can drive the frame 1 to hoist the precast component body 2 into the air and move it to a suitable position. After the frame 1 moves to a suitable position, the crane lowers the frame 1 and the precast component body 2 until the bottom ends of both ends of the frame 1 first contact other precast parts or the ground;

[0058] After the frame 1 is stably placed on the ground, observe the position of the precast component body 2. When the position of the precast component body 2 is offset, the second motor 15 can be driven, so that the output end of the second motor 15 drives the first threaded rod 11 to rotate. Through the threaded connection between the first threaded rod 11 and the first socket rod 12, and through the fixed connection between the first socket rod 12 and the first push plate 13, and the sliding connection between the first push plate 13 and the frame 1 through the first guide rod 14, the first push plate 13 can move towards the direction close to the precast component body 2. When one first push plate 13 moves towards the direction close to the precast component body 2, while the other first push plate 13 moves away from the precast component body 2 or does not contact the precast component body 2, the precast component body 2 can be driven to move left and right;

[0059] When driving the third motor 21, the third motor 21 can drive the second threaded rod 17 to rotate. Through the threaded connection between the second threaded rod 17 and the second socket rod 18, and through the fixed connection between the second socket rod 18 and the second push plate 19, and the sliding connection between the second push plate 19 and the mounting plate 16 through the second guide rod 20, the second push plate 19 can move towards the direction close to the precast component body 2. When the two second push plates 19 on one side move towards the direction close to the precast component body 2, while the two second push plates 19 on the other side move away from the precast component body 2 or do not contact the precast component body 2, the precast component body 2 can be driven to move back and forth;

[0060] When the two second push plates 19 at the diagonal angles move simultaneously, while the two second push plates 19 at the other two diagonal angles move backward simultaneously or do not contact the precast component body 2, the precast component body 2 can be driven to rotate. As shown in the attached Figure 12 figure, when the second push plate 19 at the a end and the second push plate 19 at the c end move towards the direction close to the precast component body 2 simultaneously, while the second push plates 19 at the b end and the d end do not contact the precast component body 2, the precast component body 2 can be driven to rotate slightly. Thus, through the control of the above-mentioned first push plate 13 and second push plate 19, the position of the precast component body 2 can be finely adjusted to ensure the accuracy of the placement position of the precast component body 2;

[0061] When it is necessary to lower the precast component body 2, the first motor 5 can be driven, so that the output end of the first motor 5 drives the linkage mechanism, and the linkage mechanism drives the transmission column 6 to rotate. Then, the transmission column 6 drives the transmission roller 7 to rotate. Through the connecting rope 8 wound around the outer side of the transmission roller 7, the connecting rope 8 gradually disengages from the winding of the transmission roller 7, and the hanging rope 4 is lowered. Then, the precast component body 2 is lowered to a suitable position through the hanging rope 4.

[0062] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special instructions and limitations.
