Technical Field

[0001] The invention relates to the technical field of hoisting in building construction, in particular to a quick hoisting device for assembled components and a use method thereof. Background Art

[0002] In modern construction, prefabricated buildings are widely used due to their advantages such as fast construction speed, easy quality control, and low environmental impact. The core of prefabricated buildings lies in the production and on-site hoisting of prefabricated components. In coastal areas, due to special environmental conditions such as strong winds and high humidity, higher requirements are placed on the hoisting accuracy and speed of prefabricated components. At present, the traditional method of lifting prefabricated components mainly relies on the experience and skills of the crane operator. During the lifting process, the crane first lifts the prefabricated components from the ground or the transport vehicle, and then slowly lowers them to the predetermined position. When approaching the ground, manual assistance is required to straighten the components to ensure that they are accurately positioned. This process is not only time-consuming, but also requires high skills of the operator, and it is easy to cause component damage or construction accidents due to improper operation; For example, when hoisting a prefabricated beam, the traditional method requires close cooperation between the crane operator and the ground assistant. The operator controls the lifting and movement of the lifting rope on the crane, while the ground assistant guides the operator to make fine adjustments through shouting or gestures. Due to the influence of wind in coastal areas, the components may sway in the air, making positioning difficult. In addition, during the manual straightening process, due to the limitations of vision and operating space, it is difficult to ensure the precise alignment of the components, and sometimes it even takes multiple attempts to succeed.

[0015] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. Example 1

[0016] See attached Figure 1-12 A fast lifting device for assembled components, comprising a frame 1 and a prefabricated component body 2, wherein the frame 1 is arranged in an inverted U-shape as a whole, 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 subsequent first push plate 13 and the second push plate 19 fine-tune the prefabricated component body 2, 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 on the inner side of the frame 1, and a first motor 5 is installed on the top of the prefabricated component body 2, and a linkage mechanism is installed on the output end of the first motor 5, and a transmission column 6 is installed on the end of the linkage mechanism away from the first motor 5; See attached Figure 4 The linkage mechanism includes a worm 9 fixed to the output end of the first motor 5, the outer side of the worm 9 is meshingly connected with a worm wheel 10, and the worm wheel 10 is connected to the transmission column 6; When the first motor 5 is driven, the worm 9 can be driven to rotate, and the meshing connection between the worm 9 and the worm wheel 10 can drive the worm wheel 10 to rotate, and the worm wheel 10 drives the transmission column 6 to rotate. Through the arrangement of the worm 9 and the worm wheel 10, the worm 9 can drive the worm wheel 10 to rotate, while the worm wheel 10 cannot drive the worm 9 to rotate, thereby avoiding sudden falling due to the overweight of the prefabricated component body 2, and playing a certain limiting role; The outer side of the transmission column 6 is rotatably connected with a support frame 37, and the support frame 37 is fixedly connected to the frame 1. A transmission roller 7 is fixed to the end of the transmission column 6 away from the linkage mechanism, and 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 multiple hanging ropes 4. Hooks 3 are installed at the four end corners of the top of the prefabricated component body 2, and multiple hooks 3 are respectively connected to multiple hooks 3. Through the connection between the hanging ropes 4 and the hooks 3, the prefabricated component body 2 can be hoisted on the inner side of the frame 1, and the hanging ropes 4 are arranged in a cross shape, thereby reducing the rotation amplitude of the prefabricated component body 2 when hoisting the prefabricated component body 2; When the prefabricated component body 2 needs to be lowered, 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, and then the transmission column 6 drives the transmission roller 7 to rotate, and the connecting rope 8 wrapped around the outside of the transmission roller 7 is gradually separated from the winding of the transmission roller 7, and the hanging rope 4 is lowered, and then the prefabricated component body 2 is lowered through the hanging rope 4; See attached Figure 8 , both ends of the bottom of the frame 1 are provided with mounting grooves 22, a sliding column 23 is slidably connected inside the mounting 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 mounting groove 22, and a contact piece 25 is fixed to the bottom of the sliding column 23; When the frame 1 contacts the ground, the contact piece 25 contacts the ground first, and the first spring 24 is set so that the contact piece 25 first has a certain buffering effect when contacting the ground, so as to prevent the frame 1 from vibrating too much suddenly and causing the prefabricated component body 2 to separate from the frame 1 or the prefabricated component body 2 to shake too much; See attached Figure 5 , a pushing mechanism is also installed on the frame 1, and the pushing mechanism is used to push the prefabricated component body 2 to move; See attached Figure 6 The pushing mechanism includes two first threaded rods 11 rotatably connected to the inside of the two ends of the frame 1, and the outer sides of the two first threaded rods 11 close to each other are both threadedly connected with the first sleeve rods 12, and the first sleeve rods 12 are fixed with the first pushing plate 13 at the end away from the first threaded rods 11, and the first pushing plate 13 is arranged at the corresponding position of the prefabricated component body 2, and at least one first guide rod 14 is fixed to the side of the first pushing plate 13 close to the first threaded rods 11, and the first guide rod 14 is slidably connected to the frame 1, and a second motor 15 is installed on the outer side of the frame 1 and at the position corresponding to the first threaded rods 11, and the output end of the second motor 15 is connected to the first threaded rods 11; See attached Figure 7The pushing mechanism also includes a mounting plate 16 which is fixed inside the frame 1 and located at the four end corners of the prefabricated component body 2. A second threaded rod 17 is rotatably connected inside the mounting plate 16. A second sleeve rod 18 is threadedly connected to the outer side of the second threaded rod 17 close to one end of the prefabricated component body 2. A second pushing plate 19 is fixed to one end of the second sleeve rod 18 away from the second threaded rod 17, and the second pushing plate 19 is arranged at a corresponding position of the prefabricated component body 2. A second guide rod 20 is also fixed to the side of the second pushing plate 19 close to the second threaded rod 17. The second guide rod 20 is slidably connected to the mounting plate 16. A third motor 21 is also installed on the side of the mounting plate 16 away from the second pushing plate 19 and located at a position corresponding to the second threaded rod 17. The output end of the third motor 21 is connected to the second threaded rod 17. A plurality of balls 38 are installed on the side of the first push plate 13 and the second push plate 19 close to the prefabricated component body 2. The balls 38 are arranged so that when the hanging rope 4 lowers the prefabricated component body 2, the friction between the hanging rope 4 and the first push plate 13 and the second push plate 19 can be reduced by the balls 38, so that when the first push plate 13 or the second push plate 19 pushes the prefabricated component body 2 to make a fine adjustment of the prefabricated component body 2, the prefabricated component body 2 can also be lowered; The frame 1 may also be provided with an observation device such as a monitor or a camera and a controller, and the position and angle of the prefabricated component body 2 may be detected by the observation device. When fine adjustment is required, the observation device may transmit a signal to the controller, and the controller may control the third motor 21 or the second motor 15 to start. See attached Fig. 9 A connecting frame 26 is fixed to the side of the transmission roller 7 away from the transmission column 6, and a mounting round block 27 is arranged at the center position inside the connecting frame 26. The mounting round block 27 is connected to the frame 1 through a support member, and a plurality of guide square columns 28 are slidably connected inside the mounting round block 27. A brake block 29 is fixed to one end of the guide square column 28 away from the mounting round block 27. A plurality of clamping blocks 30 are arranged at the inner wall position of the brake block 29 close to the connecting frame 26. A clamping groove 31 corresponding to the clamping block 30 is arranged on the inner wall of the connecting frame 26. The clamping block 30 on the brake block 29 can be multi-angled, and the clamping groove 31 adapts to the angle of the clamping block 30, so that when the clamping block 30 is inserted into the clamping groove 31, it can limit the rotation of the connecting frame 26 regardless of whether it rotates forward or reversely; A driving mechanism is installed inside the mounting round block 27, and the driving mechanism is used to drive the guide square column 28 to move toward the direction close to the connecting frame 26; When the driving mechanism is driven, the guide square column 28 can be controlled to move toward the outside of the mounting round block 27, thereby driving the brake block 29 and the clamping block 30 to move toward the inner wall of the connecting frame 26, so that the brake block 29 and the connecting frame 26 fit each other, and then the friction between the brake block 29 and the inner wall of the connecting frame 26 can limit the connecting frame 26. Further, the clamping block 30 is inserted into the clamping groove 31 to limit the rotation of the connecting frame 26. When the connecting frame 26 is restricted from rotating, the worm wheel 10 and the worm 9 cannot rotate either. See attached Figure 10-11 The driving mechanism includes an electromagnet 32 ​​arranged inside the mounting round block 27, and a movable magnet 33 is also arranged at one end of the guide square column 28 close to the electromagnet 32, and the magnetic poles of the movable magnet 33 and the electromagnet 32 ​​close to each other are the same. For example, if the side of the electromagnet 32 ​​close to the movable magnet 33 is the S pole, the side of the movable magnet 33 close to the electromagnet 32 ​​is the N pole, and vice versa. An assembly groove 34 is arranged inside the mounting round block 27 and on both the upper and lower sides of the guide square column 28, and sliding plates 35 are fixed on both the upper and lower sides of the guide square column 28, and the sliding plates 35 extend into the assembly groove 34, and a second spring 36 is fixed between the sliding plate 35 and the inner wall of the assembly groove 34; When the electromagnet 32 ​​is not activated, the guide square column 28 is always set inside the mounting round block 27 by the pulling force of the second spring 36, so that the block 30 will not contact 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 guide square column 28 to move away from the electromagnet 32, stretching the second spring 36, so that the block 30 and the inner wall of the connecting frame 26 are in contact with each other, and the connecting frame 26 is braked; Example 2

[0017] A method for using a quick lifting device for an assembled component, the method for using the quick lifting device is used to explain how to use the quick lifting device, and the method for using the quick lifting device comprises the following steps: When the prefabricated component body 2 is to be hoisted and moved to a suitable position, the frame 1 is first hoisted on the outside of the prefabricated component body 2 and connected to the hook 3 on the top of the prefabricated component body 2 through the hanging rope 4, and then the crane is driven so that the crane can drive the frame 1 to lift the prefabricated component body 2 into the air and move it to a suitable position. After the frame 1 is moved to a suitable position, the crane lowers the frame 1 and the prefabricated component body 2 until the bottoms of both ends of the frame 1 first contact other prefabricated parts or the ground; After the frame 1 is stably parked on the ground, the position of the prefabricated component body 2 is observed. When the position of the prefabricated 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, and through the threaded connection between the first threaded rod 11 and the first sleeve rod 12, and through the fixed connection between the first sleeve rod 12 and the first push plate 13, and the first push plate 13 is connected to the frame 1 through the sliding connection between the first guide rod 14, so that the first push plate 13 can move toward the direction close to the prefabricated component body 2. When the first push plate 13 at one end moves toward the direction close to the prefabricated component body 2, the first push plate 13 at the other end moves toward the direction away from the prefabricated component body 2 or does not contact the prefabricated component body 2, thereby driving the prefabricated component body 2 to move left and right; When the third motor 21 is driven, the second threaded rod 17 can be driven to rotate by the third motor 21, and the second threaded rod 17 and the second sleeve rod 18 are threadedly connected, and the second sleeve rod 18 and the second push plate 19 are fixedly connected, and the second push plate 19 is slidably connected between the second guide rod 20 and the mounting plate 16, so that the second push plate 19 can move toward the direction close to the prefabricated component body 2. When the two second push plates 19 on one side move toward the direction close to the prefabricated component body 2, the two second push plates 19 on the other side move toward the direction away from the prefabricated component body 2 or are not in contact with the prefabricated component body 2, thereby driving the prefabricated component body 2 to move forward and backward; When the two second push plates 19 at the oblique angles move simultaneously, and the two second push plates 19 at the other two oblique angles retreat simultaneously or are not in contact with the prefabricated component body 2, the prefabricated component body 2 can be driven to rotate. Fig.12 As shown, when the second push plate 19 at the a end and the second push plate 19 at the c end simultaneously move toward the direction close to the prefabricated component body 2, and the second push plates 19 at the b end and the d end are not in contact with the prefabricated component body 2, the prefabricated component body 2 can be driven to rotate slightly, so that the position of the prefabricated component body 2 can be finely adjusted through the control of the first push plate 13 and the second push plate 19, so as to ensure the accuracy of the placement position of the prefabricated component body 2; When the prefabricated component body 2 needs to be lowered, 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, and then the transmission roller 7 is driven to rotate through the transmission column 6, and the connecting rope 8 wrapped around the outside of the transmission roller 7 is gradually separated from the entanglement with the transmission roller 7, and the hanging rope 4 is lowered, and then the prefabricated component body 2 is lowered to a suitable position through the hanging rope 4.
