Description

Technical Field

[0001] The present invention relates to the technical field of cranes supported by buildings, and in particular to an assembled I-beam hoisting device for building construction and a use method thereof. Background Art

[0002] I-beam refers to rolled iron beam, steel beam or cast steel beam with I-shaped cross section, and also refers to composite beam with I-shaped cross section. Prefabricated I-beam is a structure made of steel materials and is one of the main types of building structures. The I-beam structure is mainly made of steel and steel plates, and its cross section is mainly I-shaped. The components or parts of the prefabricated I-beam are usually connected by welds, bolts or rivets. Because of its light construction quality, energy saving and environmental protection, fast construction speed and high degree of industrialization, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] For example, the invention with the announcement number CN111362128B discloses a hoisting device for assembled I-beams for building construction, including a lifting device, a locking device and two fixing devices, characterized in that: a locking device is installed at the lower end of the lifting device, and fixing devices are symmetrically arranged at the left and right ends of the locking device, and the fixing devices are installed at the lower end of the lifting device by sliding fit. The hoisting device for assembled I-beams for building construction provided by the present invention can solve the problems that the existing hoisting equipment usually directly hoists the assembled I-beams during the hoisting process, and does not fix and limit the assembled I-beams during the hoisting process, which easily causes the I-beams to fall off during the hoisting process, injuring the staff, and the assembled steel structure beams and columns are usually fixed and limited by ropes, steel wire ropes, etc. during the hoisting process, and the fixing and limiting effect is poor, and when the I-beams are manually fed, the process of fixing with ropes is cumbersome, thereby making the hoisting efficiency of the I-beams low.

[0004] There are still some deficiencies in the above technical solution during use:

[0005] In the above technical solution, when fixing and installing the I-beam, it is first necessary to manually place the I-beam on the support plate, and the clamping mechanism completes the fixing of the I-beam by the weight of the I-beam. Due to the lack of space above the support plate, it is extremely inconvenient to place the I-beam on the support plate by machinery. The I-beam is heavy and cannot be easily moved by humans, so it is difficult to place the I-beam on the support plate.

[0006] When completing the fixing and clamping of the I-beam, there are many manual operation steps, which are cumbersome and seriously affect the lifting efficiency of the I-beam. In addition, during the lifting process of the I-beam, it is impossible to pull the I-beam manually, so the I-beam can only be lifted to the designated position by relying on the tower crane. When placing the I-beam, the tower crane has a large error with the designated position, which increases the difficulty of moving the I-beam to the designated position.

[0007] In view of the above problems, the present invention document proposes a lifting device for assembled I-beams in building construction and a method for using the same. Summary of the invention

In addition, the movement of the T-shaped casting toward the middle can also make the first rack cooperate with the second rack to limit the fixing structure.

[0017] In a possible design, the end fixing structure includes a second rectangular groove arranged on one side of the top of the lifting plate, an L-shaped clip plate for clamping and fixing the end of the I-beam is slidably connected in the second rectangular groove, a plurality of guide rods are welded in the second rectangular groove, and the guide rods slide through the L-shaped clip plate, and a magnet block is fixedly embedded on the side of the L-shaped clip plate close to the I-beam, and two bearing plates are welded on the side of the L-shaped clip plate close to the T-shaped casting, and the two bearing plates are fixed with a second rack by bolts on the sides away from each other, and the second rack is meshed with the first rack, and the two bearing plates are fixedly supported by a plurality of support rods, and the stability between the two bearing plates can be ensured by the support rods; the two L-shaped clip plates are pushed toward the middle, and the magnetic attraction force of the magnet block on the end of the I-beam can enable the two L-shaped clip plates to clamp the two ends of the I-beam, and when the two T-shaped castings move toward the middle, the first rack just meshes with the second rack on one side of the L-shaped clip plate, thereby completing the fixation of the end of the I-beam.

[0019] The lifting mechanism is a bottom end of a bottom end of a chain, and the bottom end of a bottom end of a chain is fixedly mounted on the lifting mechanism, wherein the lifting mechanism has the advantages of being easily movable and compact, and the lifting mechanism has the advantages of being easily movable. The input shaft of the gear box is fixedly connected to one end of the rotating shaft through a coupling, and the output shaft of the gear box is fixedly connected to one end of the second winding roller through a coupling; a protective cover for protecting the gearbox is provided on one side of the lifting plate. When the top plate moves up, the top plate drives the rotating shaft and the first winding roller to rotate counterclockwise through the rope, the torsion spring starts to accumulate force, and the rotating shaft drives the second winding roller to rotate through the gearbox. Through the cooperation of the gearbox, the number of revolutions of the second winding roller can be more than the number of revolutions of the first winding roller. The second winding roller rotates counterclockwise to release the winding of the traction rope, and the staff on the building can hook the traction rope through a rod with a hook. Then the staff can complete the traction of the lifting plate by pulling the traction rope, and place the I-beam at the designated position to ensure the accuracy of the placement position and avoid the need to move the I-beam again later.

[0020] In a possible design, the two T-shaped castings are welded with connecting ears on the sides away from each other, and the tops of the two fixed bases are clamped with pins, and the fixed bases and the connecting ears can be fixed by the pins; the fixed bases and the T-shaped castings are fixed by the pins, so when the lifting plate is hoisted to the top of the I-beam, the two T-shaped castings can be maintained on both sides of the I-beam, which is convenient for the top plate to move up later to drive the T-shaped castings to move toward the middle, thereby completing the clamping and fixation of the two sides and ends of the I-beam.

[0021] In a possible design, a plurality of rollers are provided on the bottom inner wall of the U-shaped clip; when the two U-shaped clips move toward the middle, the rollers can reduce the friction between the rollers and the top inner wall of the I-beam, so that the U-shaped clips can clamp the I-beam by temperature.

[0022] In a possible design, a pad is fixed to the bottom of the I-beam by bolts, and a second magnet is fixed to the bottom of the pad by bolts; the magnetic attraction of the second magnet to the I-beam can ensure the stability of the lifting plate and prevent the lifting plate from shaking on the I-beam, and the pad can make the U-shaped clip cooperate with the two sides of the I-beam to ensure that the U-shaped clip can stably clamp the two sides of the I-beam.

Therefore, when the I-beam is hoisted to a high altitude in the later stage, the pocket belt can further ensure the stability of the I-beam and prevent the I-beam from falling and causing construction accidents.

[0024] In the present application, a method for using a building construction assembled I-beam hoisting device comprises the following steps:

[0025] S1. The tower crane is connected to the top plate through a traction hook, and the lifting plate is hoisted to the top of the I-beam through the tower crane. The cushion block touches the top of the I-beam, and the magnetic attraction between the second magnet and the I-beam increases the stability between the lifting plate and the I-beam to prevent the lifting plate from shaking. The pin rod is taken out to release the clamping between the fixed base and the connecting ear. Then the tower crane drives the top plate to move up. When the top plate moves up, the two cross plates are driven to move toward the middle through the connecting rod. The cross plate drives multiple T-shaped castings and U-shaped fasteners on one side to move toward the middle. The U-shaped fasteners on both sides can clamp and fix the two sides of the I-beam;

[0026] S2. In addition, before the top plate is moved up, the two L-shaped snap plates are pushed toward the middle, and the magnetic attraction of the magnet block on the ends of the I-beam can enable the two L-shaped snap plates to clamp the two ends of the I-beam. When the two T-shaped castings move toward the middle, the first rack just meshes with the second rack on one side of the L-shaped snap plate. Therefore, in the process of the top plate moving up, not only the two sides of the I-beam can be clamped and fixed, but also the two ends of the I-beam can be clamped and fixed. The operation is simple, and there is no need for too much manual operation, which improves the efficiency of I-beam hoisting.

[0027] S3. When the top plate rises to a certain height, the top plate lifts the I-beam upwards through the cooperation of the first steel wire rope, the second steel wire rope and the connecting rod, and then the round hole is buckled with the hook, and the bottom of the I-beam is held by the bag belt. Therefore, when the I-beam is hoisted to a high altitude in the later stage, the bag belt can further ensure the stability of the I-beam and prevent the I-beam from falling and causing construction accidents;

[0028] S4. When the top plate is moved up, the top plate drives the rotating shaft and the first winding roller to rotate counterclockwise through the rope, the torsion spring starts to accumulate force, the rotating shaft drives the second winding roller to rotate through the gearbox, and the gearbox can make the second winding roller rotate more circles than the first winding roller, the second winding roller rotates counterclockwise to release the winding of the traction rope, the staff on the building can hook the traction rope through the rod with a hook, and then the staff can pull the traction rope to complete the traction of the lifting plate, and place the I-beam at the designated position, ensuring the accuracy of the placement position, and avoiding the need to move the I-beam again later;

[0029] S5. When the I-beam is hoisted to the specified position, the tower crane releases the stretching of the top plate, and the top plate moves downward under the action of gravity. The U-shaped clip moves outward under the elastic force of the spring and the thrust of the connecting rod, releasing the clamping of the side of the I-beam. Then, the connecting ear and the fixed base are clamped again through the pin rod to facilitate the subsequent hoisting of the I-beam. The first winding roller rewinds the rope under the action of the torsion spring.

[0030] In the present invention, a fixed shaft is fixed to one side of the U-shaped fastener away from the I-beam through a welding plate, a fixing ring is sleeved on the outer wall of the fixed shaft, a pocket belt is fixed to the bottom of the fixing ring, a plurality of round holes are arranged in the pocket belt, and a plurality of hooks are welded to one side of the other U-shaped fastener away from the I-beam, and the hooks cooperate with the pocket belt; when the I-beam is lifted to a certain height, the round holes are buckled with the hooks, and the bottom of the I-beam is held by the pocket belt, so when the I-beam is lifted to a high altitude in the later stage, the pocket belt can further ensure the stability of the I-beam, and avoid the I-beam from falling and causing construction accidents;

[0031] In the present invention, the two first base plates are rotatably connected to the first winding roller through the rotating shaft, the outer wall of the first winding roller is wound with a rope fixedly connected to the top plate, the outer wall of the second winding roller is wound with a traction rope, and the rotating shaft and the second winding roller are connected through a gearbox; the top plate drives the first winding roller to rotate counterclockwise by pulling the rope, the rotating shaft drives the second winding roller to rotate through the gearbox, the second winding roller rotates counterclockwise to release the winding of the traction rope, and then the staff can complete the traction of the lifting plate by pulling the traction rope, and place the I-beam at the specified position, thereby ensuring the accuracy of the placement position and avoiding the need to move the I-beam again later;

[0032] In the present invention, two T-shaped castings are slidably connected in the two first rectangular grooves, and a U-shaped clip is welded at the bottom end of the T-shaped casting. The first rack is fixed to the side of the two T-shaped castings close to each other by bolts, and the first rack is used to limit the end fixing structure; the two T-shaped castings move toward the middle, and the two U-shaped clips can just clamp and fix the two sides of the I-beam, which is simple to operate. In addition, the movement of the T-shaped casting toward the middle can also make the first rack cooperate with the second rack to limit the fixing structure;

[0033] In the present invention, both sides of the bottom of the top plate are rotatably connected with multiple connecting rods, and the bottom ends of the multiple connecting rods located on the same side are rotatably connected with the same cross plate, and the cross plate is welded to the top fixation of multiple T-shaped castings located on the same side; when the top plate moves up, the two cross plates are driven to move toward the middle by the connecting rods, and the cross plate drives multiple T-shaped castings and U-shaped clips on one side to move toward the middle, and the two sides of the I-beam can be clamped and fixed by the U-shaped clips on both sides, and the T-shaped casting can also limit the L-shaped clip plate when it moves, so as to fix the end of the I-beam.

[0034] In the present invention, the rise of the top plate can drive the T-shaped casting and the U-shaped clip to move toward the middle, and the T-shaped casting can limit the L-shaped clip plate when it moves, so there is no need for manual operation. The rise of the top plate can automatically clamp and fix the two sides and both ends of the I-beam, which is simple to operate and improves the efficiency of lifting the I-beam. In addition, when the top plate rises, the reeling of the traction rope can be released, and then the staff can pull the lifting plate and the I-beam through the traction rope to ensure the accuracy of the placement position of the I-beam, avoiding the need to move the I-beam again at a later time.

[0059] Example 2

[0060] refer to Fig. 9 and Fig.10, an improvement on Example 1: a fixed shaft 39 is fixed to one side of the U-shaped fastener 5 away from the I-beam 2 through a welding plate, a fixing ring 40 is sleeved on the outer wall of the fixed shaft 39, a pocket belt 41 is fixed to the bottom of the fixing ring 40, a plurality of round holes 42 are arranged in the pocket belt 41, and a plurality of hooks 43 are welded to the other side of the U-shaped fastener 5 away from the I-beam 2, and the hooks 43 cooperate with the pocket belt 41; when the top plate 22 rises to a certain height, the top plate 22 lifts the I-beam 2 upward through the cooperation of the first steel wire rope 26, the second steel wire rope 44 and the connecting rod 23, and then the round holes 42 are buckled with the hooks 43, and the bottom of the I-beam 2 is held by the pocket belt 41. Therefore, when the I-beam 2 is hoisted to a high altitude in the later stage, the pocket belt 41 can further ensure the stability of the I-beam 2 and prevent the I-beam 2 from falling and causing construction accidents.

[0061] A method for using a building construction assembled I-beam hoisting device comprises the following steps:

[0062] S1. The tower crane is connected to the top plate 22 through the traction hook 28, and the lifting plate 1 is hoisted to the top of the I-beam 2 through the tower crane. The cushion block 45 touches the top of the I-beam 2, and the magnetic attraction between the second magnet 46 and the I-beam 2 increases the stability between the lifting plate 1 and the I-beam 2 to prevent the lifting plate 1 from shaking. The pin rod 12 is taken out to release the clamping between the fixed base 8 and the connecting ear 11, and then the tower crane drives the top plate 22 to move upward. When the top plate 22 moves upward, the two cross plates 21 are driven to move toward the middle through the connecting rod 23. The cross plate 21 drives multiple T-shaped castings 4 and U-shaped fasteners 5 on one side to move toward the middle, and the U-shaped fasteners 5 on both sides can clamp and fix the two sides of the I-beam 2;

[0063] S2. In addition, before the top plate 22 moves up, the two L-shaped snap plates 16 are pushed toward the middle, and the magnetic attraction of the magnet block 17 on the ends of the I-beam 2 enables the two L-shaped snap plates 16 to clamp the two ends of the I-beam 2. When the two T-shaped castings 4 move toward the middle, the first rack 13 just meshes with the second rack 19 on one side of the L-shaped snap plate 16. Therefore, in the process of the top plate 22 moving up, not only the two sides of the I-beam 2 can be clamped and fixed, but also the two ends of the I-beam 2 can be clamped and fixed. The operation is simple, and no excessive manual operation is required, thereby improving the efficiency of hoisting the I-beam 2.

[0064] S3. When the top plate 22 rises to a certain height, the top plate 22 lifts the I-beam 2 upwards through the cooperation of the first steel wire rope 26, the second steel wire rope 44 and the connecting rod 23, and then the round hole 42 is buckled with the hook 43, and the bottom of the I-beam 2 is held by the pocket belt 41. Therefore, when the I-beam 2 is hoisted to a high altitude in the later stage, the pocket belt 41 can further ensure the stability of the I-beam 2, and prevent the I-beam 2 from falling and causing construction accidents;

[0065] S4. When the top plate 22 moves up, the top plate 22 drives the rotating shaft 30 and the first winding roller 31 to rotate counterclockwise through the rope 33, the torsion spring 32 starts to accumulate force, and the rotating shaft 30 drives the second winding roller 35 to rotate through the gearbox 38. The gearbox 38 cooperates to make the second winding roller 35 rotate more circles than the first winding roller 31. The second winding roller 35 rotates counterclockwise to release the winding of the traction rope 36. The staff on the building can hook the traction rope 36 through the rod with a hook, and then the staff can complete the traction of the lifting plate 1 by pulling the traction rope 36, and place the I-beam 2 at the specified position, ensuring the accuracy of the placement position and avoiding the need to move the I-beam 2 again later.

[0066] S5. When the I-beam 2 is hoisted to the specified position, the tower crane releases the stretching of the top plate 22, and the top plate 22 moves downward under the action of gravity. The U-shaped clip 5 moves outward under the elastic force of the spring 10 and the thrust of the connecting rod 23, releasing the clamping of the side of the I-beam 2. Then, the connecting ear 11 and the fixed base 8 are clamped again through the pin rod 12, so as to facilitate the subsequent hoisting of the I-beam 2. The first winding roller 31 rewinds the rope 33 under the action of the torsion spring 32.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The tower crane is connected to the top plate (22) through a traction hook (28). The tower crane is used to hoist the lifting plate (1) to the top of the I-beam (2). The cushion block (45) contacts the top of the I-beam (2). The magnetic attraction between the second magnet (46) and the I-beam (2) increases the stability between the lifting plate (1) and the I-beam (2) to prevent the lifting plate (1) from shaking. The pin rod (12) is removed to release the clamping between the fixed base (8) and the connecting ear (11). Then, the tower crane drives the top plate (22) to move upward. When the top plate (22) moves upward, the connecting rod (23) drives the two cross plates (21) to move toward the middle. The cross plate (21) drives the multiple T-shaped castings (4) and the U-shaped clips (5) on one side to move toward the middle. The U-shaped clips (5) on both sides can clamp and fix the two sides of the I-beam (2). S2. In addition, before the top plate (22) moves upward, the two L-shaped snap plates (16) are pushed toward the middle, and the two L-shaped snap plates (16) can clamp the two ends of the I-beam (2) through the magnetic attraction of the magnet block (17) on the end of the I-beam (2). When the two T-shaped castings (4) move toward the middle, the first rack (13) just meshes with the second rack (19) on one side of the L-shaped snap plates (16). Therefore, in the process of the top plate (22) moving upward, not only the two sides of the I-beam (2) can be clamped and fixed, but also the two ends of the I-beam (2) can be clamped and fixed; S3, when the top plate (22) rises to a certain height, the top plate (22) lifts the I-beam (2) upwards through the cooperation of the first steel wire rope (26), the second steel wire rope (44) and the connecting rod (23), and then the round hole (42) is locked with the hook (43), and the bottom of the I-beam (2) is held by the bag belt (41); S4.

The gearbox (38) cooperates to enable the second winding roller (35) to rotate more turns than the first winding roller (31). The second winding roller (35) rotates counterclockwise to release the winding of the traction rope (36). The staff on the building can hook the traction rope (36) through the rod with a hook. Then, the staff can pull the traction rope (36) to complete the traction of the lifting plate (1) and place the I-beam (2) at the designated position. S5. When the I-beam (2) is hoisted to the specified position, the tower crane releases the tension on the top plate (22), and the top plate (22) moves downward under the action of gravity. The U-shaped clip (5) moves outward under the elastic force of the spring (10) and the thrust of the connecting rod (23), releasing the clamping of the side of the I-beam (2). Then, the connecting ear (11) and the fixed base (8) are clamped again through the pin rod (12), so as to facilitate the subsequent hoisting of the I-beam (2). The first winding roller (31) rewinds the rope (33) under the action of the torsion spring (32).
