Description

Technical Field

[0001] The present invention relates to the technical field of hollow sandwich panel hoisting, in particular to assembled hollow sandwich panel hoisting equipment and a hoisting method. Background Art

[0002] The prefabricated hollow sandwich panel is composed of a thin concrete plate on the surface and a steel hollow beam underneath. It fully utilizes the compressive properties of concrete and the good tensile properties of steel. It is mainly used in large-span floor structures. The steel structure is mainly composed of upper ribs, lower ribs and shear keys. During the construction process, the steel structure is lifted and assembled by lifting equipment.

[0003] The existing lifting equipment for assembled hollow sandwich panels is mainly connected to the tower crane through hooks and chains. The lifting operation is achieved by fixing the lifting belt to the steel structure and then connecting the other end of the lifting belt to the hook. However, this manual method of connecting the workpiece to be lifted and the lifting equipment is relatively cumbersome and has certain safety hazards. Moreover, after the steel structure is lifted to the designated position, the staff needs to assemble and connect the newly lifted steel structure with the steel structure on the floor. However, with the above lifting method, there is a great deal of uncertainty in the posture of the steel structure. Therefore, the staff needs to manually push the lifted steel structure workpiece to make it correspond to the posture of the steel structure on the floor, which leads to the problems of cumbersome lifting operation, manual positioning, and low positioning accuracy.

Through the rotation of the annular chain 1 and the annular chain 2, the posture of the hoisted assembled hollow sandwich plate steel structure can be adjusted;

[0007] The magnetic lifting group includes magnetic suction blocks, and the magnetic suction blocks are provided in multiple groups with uniform distribution. The magnetic suction blocks can perform multi-point distributed magnetic lifting on the assembled hollow sandwich plate steel structure.

[0008] Furthermore, the main lifting connection includes a main lifting ring, a connecting hook 1, a main lifting chain, a connecting block, and a connecting hook 2.

[0010] Furthermore, the magnetic lifting group also includes a fixed plate, a branch hanger, a branch lifting ring 1, a connecting hook 3, a branch lifting chain, a connecting hook 4, a branch lifting ring 2, and a rotating ring.

[0011] Furthermore, the lower side of the branch chain is fixedly connected to a connecting hook four, the lower side of the connecting hook four is clamped with a branch ring two, the lower side of the branch ring two is sleeved with a rotating ring, and the lower side of the rotating ring is rotatably connected to a magnetic suction block.

[0012] Since the magnetic suction block is composed of a coil, an iron core and a magnet, the coil generates a magnetic field when energized, and the iron core concentrates the magnetic lines of force to form a closed magnetic circuit, so that the magnetic suction block magnetically adsorbs the steel structure workpiece. According to the length of the steel structure workpiece, the motor 1 at each location is controlled to start, and the motor 1 drives the gear to rotate, so that the gear engages with the rack during the rotation process, thereby driving the slider and the moving plate to slide linearly along the guide rail 1, and then the multiple groups of magnetic lifting groups are evenly dispersed according to the length of the steel structure workpiece, and the coil inside the magnetic suction block is passed through When current is input, the magnetic suction block generates magnetic force, thereby adsorbing the steel structure workpiece to be hoisted. Since the rotating ring and the magnetic suction block are rotatably connected, after the magnetic suction block contacts and adsorbs the steel structure workpiece, the external lifting mechanism is activated, and the steel structure workpiece is lifted through the connection of the branch hanger, branch lifting ring 1, connecting hook 3, branch lifting chain, connecting hook 4, and branch lifting ring 2. Since there are multiple groups of magnetic suction blocks and they are evenly distributed and in contact with the steel structure, the purpose of multi-point distributed magnetic lifting is achieved;

[0013] Furthermore, the lifting assembly includes a third motor, a fixed seat, a mounting shell, a second guide rail, a screw rod, a movable block, and a movable plate. Both ends of the support frame are fixedly connected to the fixed seat, the fixed seat is fixedly connected to the mounting shell on the side away from the support frame, the upper side of the mounting shell is fixedly connected to the third motor, the mounting shell is fixedly connected to the second guide rail on the side away from the support frame, the output end of the third motor is fixedly connected to the screw rod, the screw rod and the mounting shell are rotatably connected, the outer side of the screw rod is threadedly connected to the movable block, the outer side of the guide rail two is slidably connected to the movable plate, the movable plate and the movable block are fixedly connected, and the side of the movable plate away from the movable block is fixedly connected to the connecting seat.

[0014] Furthermore, the adjustable lifting group also includes a connecting shell, a pushing component, a second motor, a bearing seat, and a connecting hook five. The lower side of the connecting seat is fixedly connected to the connecting shell, the inner side of the connecting shell is fixedly connected to the pushing component, the outer side of the connecting shell is fixedly connected to the second motor, and the output end of the second motor is fixed with a shaft assembly.

[0015] Furthermore, the shaft assembly includes connecting shaft 1 and connecting shaft 2. The inner side of sprocket 1 is fixedly connected to connecting shaft 2, and the inner side of sprocket 2 is fixedly connected to connecting shaft 1. Connecting shaft 1 is clamped with connecting shaft 2, and connecting shaft 2 rotates synchronously with connecting shaft 1.

[0016] After the steel structure workpiece is hoisted to the designated position by the external hoisting mechanism, it is assembled and docked. According to the posture of the steel structure workpiece at this time, when the posture is tilted, the motor 2 is started, and the motor 2 drives the connecting shaft 2 to rotate. Since a protrusion is provided on the outside of the connecting shaft 2, and a groove corresponding to the protrusion is provided on the inside of the connecting shaft 1, while the connecting shaft 2 rotates, the connecting shaft 1 is synchronously driven to rotate, and then the sprocket 1 and the sprocket 2 are driven to rotate synchronously, and then the steel structure workpiece inside is driven to flip at a small angle to adjust the posture. In the process of flipping the steel structure workpiece, the magnetic suction block is always on the upper side of the steel structure workpiece. When it is adjusted to the appropriate posture, the staff controls to start the lifting assembly. At this time, the branch lifting chain is in a relaxed state. The lifting assembly drives the steel structure workpiece to move downward and gradually reach the assembly station. At this time, the branch lifting chain is in a taut state.

[0018] After the steel structure workpiece is lifted off the ground by the magnetic suction block, motor three is started, and motor three drives the screw rod to rotate. The screw rod drives the movable block and movable plate to slide downward along guide rail two through the action of the thread, and then drives the adjustable lifting group to move downward as a whole, so that the ring chain one and the ring chain two reach the position matching the steel structure workpiece. When the ring chain one and the ring chain two are sleeved on the outside of the steel structure workpiece, the telescopic cylinder can be started according to the weight distribution of the steel structure workpiece. The telescopic cylinder drives the moving block to slide linearly on the guide rod, and then drives the inner sprocket two and the ring chain two to move linearly, so as to achieve the purpose of adjusting the distance between the ring chain one and the ring chain two, and meet the requirements of hoisting stability of steel structure workpieces with different weight distributions.

[0019] The ring chain 1 and the ring chain 2 are separated from the steel structure workpiece by connecting hook 5, and then the power in the magnetic suction block is cut off to separate the magnetic suction block from the steel structure workpiece. At this point, the lifting operation is completed.

[0020] A method for hoisting an assembled hollow sandwich panel hoisting device comprises the following steps:

[0021] S1. Magnetic lifting: According to the length of the steel structure workpiece, evenly distribute the magnetic suction blocks, energize the magnetic suction blocks to perform multi-point magnetic lifting of the steel structure workpiece;

[0022] S2. Adjust the outer lifting distance; according to the weight distribution of the steel structure workpiece, adjust the distance between the ring chain 1 and the ring chain 2 to meet the requirements of lifting stability;

[0024] S4. Lifting, positioning and posture adjustment: Lift the steel structure workpiece to the specified position, perform fine displacement positioning through the lifting assembly, and use the ring chain 1 and ring chain 2 to drive the steel structure workpiece to flip at a small angle and adjust its posture;

[0025] S5. Separation of slings: After the steel structure workpiece is assembled, the ring chain 1 and the ring chain 2 are separated from the steel structure workpiece through the connecting hook 5, and the magnetic suction block is powered off and separated.

[0026] Compared with the prior art, the present invention provides a prefabricated hollow sandwich panel hoisting device and hoisting method, which has the following beneficial effects:

[0027] 1. The present invention changes the existing lifting method of using slings through the cooperation between the mobile mechanism and the magnetic lifting group. Through the evenly dispersed magnetic suction blocks, the purpose of multi-point evenly distributed magnetic lifting of steel structure workpieces is achieved, the lifting operation method is simplified, the lifting efficiency is improved, and the lifting stability is improved.

[0028] 2. The present invention can adjust the distance between the ring chain one and the ring chain two according to the weight distribution of the steel structure workpiece through the cooperation between the adjustable lifting group, the lifting assembly, and the shaft assembly, so as to meet the lifting stability requirements of steel structure workpieces with different weight distributions. At the same time, after the steel structure workpiece reaches the position, the ring chain one and the ring chain two can be controlled to rotate, thereby driving the steel structure workpiece to flip and adjust the posture.

[0053] Since the magnetic suction block 49 is composed of a coil, an iron core and a magnetic conductor, the coil generates a magnetic field when energized, and the iron core concentrates the magnetic lines of force to form a closed magnetic circuit, so that the magnetic suction block 49 magnetically attracts the steel workpiece. According to the length of the steel workpiece, the motor 32 at each location is controlled to start, and the motor 32 drives the gear 33 to rotate, so that the gear 33 engages with the rack 34 during the rotation process, thereby driving the slider 36 and the moving plate 37 to slide linearly along the guide rail 35, and then the multiple groups of magnetic lifting groups 4 are evenly dispersed according to the length of the steel workpiece, so as to evenly attract the coils inside the magnetic suction block 49. When current is applied, the magnetic suction block 49 generates magnetic force, thereby adsorbing the steel structure workpiece to be hoisted. Since the rotating ring 48 and the magnetic suction block 49 are rotatably connected, after the magnetic suction block 49 contacts and adsorbs the steel structure workpiece, the external hoisting mechanism is activated, and the steel structure workpiece is hoisted through the connection of the branch hanger 42, the branch lifting ring 1 43, the connecting hook 3 44, the branch lifting chain 45, the connecting hook 46, and the branch lifting ring 2 47. Since there are multiple groups of magnetic suction blocks 49, which are evenly distributed and in contact with the steel structure, the purpose of multi-point distributed magnetic hoisting is achieved.

[0054] Furthermore, the lifting assembly 6 includes a motor three 61, a fixed seat 62, a mounting shell 63, a guide rail two 64, a screw rod 65, a movable block 66, and a movable plate 67.

The connecting shaft 1 71 is clamped with the connecting shaft 2 72, and the connecting shaft 2 72 rotates synchronously with the connecting shaft 1 71.

[0057] After the ring chain 1 57 and the ring chain 2 58 are sleeved on the outside of the steel structure workpiece, the motor 3 61 is started again, so that the motor 3 61 drives the screw rod 65 to reverse, and then drives the adjustable lifting group 5 to move upward as a whole. During the upward movement, the ring chain 1 57 and the ring chain 2 58 gradually bear the weight of the steel structure workpiece. At the same time, as the ring chain 1 57 and the ring chain 2 58 move upward, the branch lifting chain 45 gradually becomes relaxed.

[0058] When the steel structure workpiece is hoisted to the designated position by the external hoisting mechanism, it is assembled and docked. According to the posture of the steel structure workpiece at this time, when the posture has a small angle of inclination, the motor 2 53 is started, and the motor 2 53 drives the connecting shaft 2 72 to rotate. Since a protrusion is provided on the outer side of the connecting shaft 2 72, and a groove corresponding to the protrusion is provided on the inner side of the connecting shaft 1 71, while the connecting shaft 2 72 rotates, the connecting shaft 1 71 is synchronously driven to rotate, thereby driving the sprocket 1 54 and the sprocket 2 55 to rotate synchronously, thereby driving the steel structure workpiece inside thereof to flip at a small angle and adjust the posture. In the process of flipping the steel structure workpiece, the magnetic suction block 49 is always on the upper side of the steel structure workpiece.

The mounting block 525 is fixedly connected to the bearing seat 56 at the sprocket 2 55, and the bearing seat 56 at the sprocket 1 54 is fixedly connected to the inner wall of the connecting shell 51.

[0060] After the steel structure workpiece is lifted off the ground by the magnetic suction block 49, the motor three 61 is started, and the motor three 61 drives the screw rod 65 to rotate. The screw rod 65 drives the movable block 66 and the movable plate 67 to slide downward along the guide rail 2 64 through the action of the thread, thereby driving the adjustable lifting group 5 to move downward as a whole, so that the ring chain 1 57 and the ring chain 2 58 reach a position matching the steel structure workpiece. When the ring chain 1 57 and the ring chain 2 58 are sleeved on the outside of the steel structure workpiece, the telescopic cylinder 522 can be started according to the weight distribution of the steel structure workpiece. The telescopic cylinder 522 drives the moving block 524 to slide linearly on the guide rod 523, and then drives the inner sprocket 2 55 and the ring chain 2 58 to move linearly, thereby achieving the purpose of adjusting the distance between the ring chain 1 57 and the ring chain 2 58, and meeting the lifting stability requirements of steel structure workpieces with different weight distributions.

[0061] The ring chain 1 57 and the ring chain 2 58 are separated from the steel structure workpiece by connecting hook 5 59, and then the power in the magnetic suction block 49 is cut off, so that the magnetic suction block 49 is separated from the steel structure workpiece, and the lifting operation is completed.

Attaching the outer lifting chain: Adjust the ring chain 1 57 and the ring chain 2 58 to the position below the steel structure workpiece through the lifting assembly 6, attach them to the outer side, and then raise the ring chain 1 57 and the ring chain 2 58 through the lifting assembly 6 to relax the branch lifting chain 45.

[0066] S4, lifting, positioning and posture adjustment; lifting the steel structure workpiece to the specified position, performing fine displacement positioning through the lifting assembly 6, and driving the steel structure workpiece to flip at a small angle through the ring chain 1 57 and the ring chain 2 58 to adjust the posture;

[0067] S5. Separation of the sling: After the steel structure workpiece is assembled, the ring chain 1 57 and the ring chain 2 58 are separated from the steel structure workpiece by the connecting hook 5 59, and the magnetic suction block 49 is powered off and separated.

[0068] The specific usage and function of this embodiment are as follows:

[0069] When in use, first, the main lifting ring 11 in the device is fixedly connected to the external lifting power mechanism, and the lifting device is transported to the assembled hollow sandwich plate steel structure area through the external lifting mechanism;

[0070] Since the magnetic suction block 49 is composed of a coil, an iron core and a magnetic conductor, the coil generates a magnetic field when energized, and the iron core concentrates the magnetic lines of force to form a closed magnetic circuit, so that the magnetic suction block 49 magnetically attracts the steel workpiece. According to the length of the steel workpiece, the motor 32 at each location is controlled to start, and the motor 32 drives the gear 33 to rotate, so that the gear 33 engages with the rack 34 during the rotation process, thereby driving the slider 36 and the moving plate 37 to slide linearly along the guide rail 35, and then the multiple groups of magnetic lifting groups 4 are evenly dispersed according to the length of the steel workpiece, so as to evenly attract the coils inside the magnetic suction block 49. When current is applied, the magnetic suction block 49 generates magnetic force, thereby adsorbing the steel structure workpiece to be hoisted. Since the rotating ring 48 and the magnetic suction block 49 are rotatably connected, after the magnetic suction block 49 contacts and adsorbs the steel structure workpiece, the external hoisting mechanism is activated, and the steel structure workpiece is hoisted through the connection of the branch hanger 42, the branch lifting ring 1 43, the connecting hook 3 44, the branch lifting chain 45, the connecting hook 46, and the branch lifting ring 2 47. Since there are multiple groups of magnetic suction blocks 49, which are evenly distributed and in contact with the steel structure, the purpose of multi-point distributed magnetic hoisting is achieved.

[0071] After the steel structure workpiece is lifted off the ground by the magnetic suction block 49, the motor three 61 is started, and the motor three 61 drives the screw rod 65 to rotate. The screw rod 65 drives the movable block 66 and the movable plate 67 to slide downward along the guide rail 2 64 through the action of the thread, thereby driving the adjustable lifting group 5 to move downward as a whole, so that the ring chain 1 57 and the ring chain 2 58 reach a position matching the steel structure workpiece. When the ring chain 1 57 and the ring chain 2 58 are sleeved on the outside of the steel structure workpiece, the telescopic cylinder 522 can be started according to the weight distribution of the steel structure workpiece, and the telescopic cylinder 522 drives the moving block 524 to slide linearly on the guide rod 523, thereby driving the inner sprocket 2 55 and the ring chain 2 58 to perform linear motion, thereby achieving the purpose of adjusting the distance between the ring chain 1 57 and the ring chain 2 58, and meeting the requirements of hoisting stability of steel structure workpieces with different weight distributions;

[0072] After the ring chain 1 57 and the ring chain 2 58 are sleeved on the outside of the steel structure workpiece, the motor 3 61 is started again, so that the motor 3 61 drives the screw rod 65 to reverse, and then drives the adjustable lifting group 5 to move upward as a whole. During the upward movement, the ring chain 1 57 and the ring chain 2 58 gradually bear the weight of the steel structure workpiece. At the same time, as the ring chain 1 57 and the ring chain 2 58 move upward, the branch lifting chain 45 gradually becomes relaxed.

[0073] When the steel structure workpiece is hoisted to the designated position by the external hoisting mechanism, it is assembled and docked. According to the posture of the steel structure workpiece at this time, when the posture has a small angle of inclination, the motor 2 53 is started, and the motor 2 53 drives the connecting shaft 2 72 to rotate. Since a protrusion is provided on the outer side of the connecting shaft 2 72, and a groove corresponding to the protrusion is provided on the inner side of the connecting shaft 1 71, while the connecting shaft 2 72 rotates, the connecting shaft 1 71 is synchronously driven to rotate, thereby driving the sprocket 1 54 and the sprocket 2 55 to rotate synchronously, thereby driving the steel structure workpiece inside thereof to flip at a small angle and adjust the posture. In the process of flipping the steel structure workpiece, the magnetic suction block 49 is always on the upper side of the steel structure workpiece. When it is adjusted to a suitable posture, the staff controls to start the lifting assembly 6. Since the branch lifting chain 45 is in a relaxed state at this time, the lifting assembly 6 drives the steel structure workpiece to move downward and gradually reach the assembly station. At this time, the branch lifting chain 45 is in a taut state;

[0074] The steel structure workpiece is installed with the workpiece to be docked. After the installation is completed, the ring chain 1 57 and the ring chain 2 58 are separated from the steel structure workpiece through the connecting hook 5 59, and then the power in the magnetic suction block 49 is cut off to separate the magnetic suction block 49 from the steel structure workpiece. At this point, the lifting operation is completed.

[0075] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
