Description

Technical Field

[0001] The present invention relates to the technical field of construction lifting tools, and particularly relates to an efficient lifting tool structure for steel skeleton construction. Background Art

[0002] The steel skeleton is the main load-bearing structure system of a building, which is composed of steel sections such as I-beams, channel steels, angle steels, etc. and steel plates through welding, bolt connection and other methods to form basic components such as beams, columns, and trusses. These components are interconnected to form a complete spatial force-bearing system, which bears the vertical and horizontal loads of the building. Steel has high strength and toughness. Compared with other building materials such as concrete, the steel skeleton can bear greater loads and is suitable for building large-span, high-rise and super-high-rise buildings. Under the condition of meeting the same load-bearing capacity requirements, the self-weight of the steel skeleton is much lighter than that of the reinforced concrete structure, which is beneficial to reducing the burden on the foundation, lowering the project cost, and also facilitating transportation and installation.

[0003] When the existing lifting tools are used for construction hoisting of steel skeletons, due to the differences in the sizes of steel skeletons required in different construction environments, the hoisting positions need to be replaced and adjusted when hoisting steel skeletons of different sizes.

[0039] As Figures 1 to 10As shown, an embodiment of the present invention provides an efficient lifting tool structure for steel skeleton construction, including a suspension plate 1. A sling 2 is connected to the bottom end of the suspension plate 1. The bottom end of the sling 2 is connected to a lifting tool bottom plate 3. A limiting rod 30 is installed on the inner wall of the bottom end of the lifting tool bottom plate 3. A first motor 4 is installed on one side of the bottom end of the lifting tool bottom plate 3. A wire winding roller 5 is installed at the bottom end of the lifting tool bottom plate 3. The number of wire winding rollers 5 is set to two groups. Wire ropes 6 are wound around the surfaces of the two groups of wire winding rollers 5. An adjusting assembly 7 is installed at the bottom end of the lifting tool bottom plate 3. The adjusting assembly 7 is used for... A wire releasing assembly 8 is installed on one side of the bottom end of the adjusting assembly 7. The wire releasing assembly 8 is used to cooperate with the adjusting assembly 7 to wind and release the wire rope 6. A locking assembly 9 is installed at the bottom end of the adjusting assembly 7. The locking assembly 9 is used to cooperate with the wire releasing assembly 8 to achieve locking. The wire releasing assembly 8 is located on one side of the bottom end of the adjusting assembly 7, and the locking assembly 9 is located at the bottom end of the adjusting assembly 7.

[0040] By setting the adjusting assembly 7, the lifting requirements of steel skeletons with different widths can be adapted, improving the applicability when lifting steel skeletons with different widths. By setting the wire releasing assembly 8, through the cooperation between the wire tightening disc 84 and the wire loosening disc 85, the winding and releasing effect of the wire rope 6 is switched, and at the same time, it cooperates with the adjusting assembly 7 for the winding effect of the wire winding roller 5 to ensure the triggering effect of the wire rope 6 on the locking assembly 9. By setting the locking assembly 9, the bottom of the steel skeleton frame position is closely attached through the support plate 914. Through the cooperation between the buckle 912 and the support plate 914, the locking effect on the steel skeleton frame position is achieved. At the same time, when lifting the steel skeleton, the contact degree between the steel skeleton frame position and the buckle 912 and the support plate 914 is ensured, improving the stability of the buckle 912 when lifting the steel skeleton. At the same time, it cooperates with the left-right balance effect of the adjusting assembly 7 to further improve the stability when lifting the steel skeleton, avoiding the steel skeleton from tilting and shaking during lifting and reducing the accident probability during steel skeleton lifting.

[0041] Such as Figures 3 to 4As shown in the figure, the adjusting assembly 7 includes a rotating rod 71. The rotating rod 71 is connected to the first motor 4. One end of the rotating rod 71 is provided with a bevel gear set 72. The middle surface of the rotating rod 71 is sleeved with a driving wheel 73. The bottom end of the driving wheel 73 contacts a pulley set 74. The pulley set 74 is installed at the bottom edge of the spreader bottom plate 3. The two pulleys in the pulley set 74 are respectively connected to one end of the two wire winding rollers 5. One of the bevel gears in the bevel gear set 72 is connected to one end of the rotating rod 71. The inner wall of the other bevel gear in the bevel gear set 72 is sleeved with a bidirectional screw 75. The two thread directions on the surface of the bidirectional screw 75 are opposite. The bidirectional screw 75 is nested and installed on the inner wall of the bottom end of the spreader bottom plate 3. The surface of the bidirectional screw 75 is threadedly sleeved with a sliding base 76. The top end of the sliding base 76 is provided with a limiting ring 77. The inner wall of the limiting ring 77 contacts the surface of the limiting rod 30. The bottom end of the sliding base 76 is provided with an electric slide rail 78. The surface of the electric slide rail 78 is sleeved with a positioning block 79. One end surface of the positioning block 79 is provided with a laser sensor 710.

[0042] The hanging plate 1 drives the spreader bottom plate 3 above the steel skeleton through the sling 2. Subsequently, according to the frame width of the steel skeleton, the operator starts the first motor 4. After the first motor 4 starts, it drives the rotating rod 71 to rotate synchronously. After the rotating rod 71 rotates, it drives the input end of the bevel gear set 72 to rotate synchronously. While the input end of the bevel gear set 72 rotates, it meshes with the output end of the bevel gear set 72 to rotate synchronously. While the output end of the bevel gear set 72 rotates, it drives the bidirectional screw 75 to rotate synchronously. Under the rotation of the bidirectional screw 75, the sliding base 76 threadedly sleeved on the outer surface of the bidirectional screw 75 slides. While the sliding base 76 slides, it drives the limiting ring 77 at the top end to slide along the direction of the limiting rod 30. At the same time, through the relative sliding effect of the two sliding bases 76, while the sliding base 76 slides, it drives the positioning block 79 to slide synchronously through the electric slide rail 78, so that the mounting box 91 at the bottom end of the positioning block 79 reaches the bottom side of the frame position of the steel skeleton.

[0043] Subsequently, the operator starts the electric slide rail 78. Under the action of the electric slide rail 78, the positioning block 79 first slides downward along the direction of the electric slide rail 78. While the positioning block 79 slides, it drives the laser sensor 710 and the mounting box 91 to slide downward synchronously. While the mounting box 91 slides, it drives the support plate 914 to be located at the bottom side of the frame position of the steel skeleton. Subsequently, the first motor 4 drives the rotating rod 71 and the input end of the bevel gear set 72 to rotate synchronously. Under the rotation of the bidirectional screw 75, the two sliding bases 76 continue to slide, so that the mounting box 91 is located at the bottom of the frame position of the steel skeleton.

[0044] During this process, while the rotating rod 71 rotates, it drives the driving wheel 73 to rotate synchronously. While the driving wheel 73 rotates, it contacts the belt in the pulley group 74. Under the driving of the driving wheel 73, the belt drives the two pulleys in the pulley group 74 to rotate synchronously. While the two pulleys in the pulley group 74 rotate, they drive the two winding rollers 5 to rotate synchronously, so that the wire ropes 6 wound on the surfaces of the two winding rollers 5 are loosened. By paying out the wire ropes 6, and cooperating with the sliding effect of the sliding base 76 driving the mounting box 91, the distance between the two mounting boxes 91 is adjusted to adapt to steel skeletons of different widths;

[0045] Meanwhile, during the hoisting process of the steel skeleton, through the induction effect between the laser sensors 710 at one ends of the two positioning blocks 79, the balance state of the steel skeleton during hoisting is detected, and through the sliding fit between the sliding base 76 and the positioning blocks 79, the two mounting boxes 91 are kept in a balanced state, so that the steel skeleton is always in a left-right balanced state during hoisting, avoiding the inclination of the steel skeleton during hoisting, and improving the safety of the steel skeleton during hoisting while improving the hoisting efficiency of the steel skeleton.

[0046] By setting the cooperation of the bevel gear set 72, the bidirectional screw 75 and the sliding base 76, the positions of the two mounting boxes 91 in the locking assembly 9 are changed in real time, so as to adapt to the hoisting requirements of steel skeletons of different widths and improve the applicability when hoisting steel skeletons of different widths.

[0047] As Figures 5 to 6 shown, the wire paying-out assembly 8 includes a second motor 81, the second motor 81 is installed on one side of the sliding base 76, a toothed ring 82 is connected to one end of the second motor 81, a first spur gear 83 is meshed on one side of the toothed ring 82, the number of the first spur gears 83 is set to two groups, both groups of the first spur gears 83 are installed on one side of the sliding base 76, a tight wire reel 84 is connected to one end of one of the two groups of the first spur gears 83, the tight wire reel 84 is installed on one side of the sliding base 76, a loose wire reel 85 is connected to one end of the other group of the two groups of the first spur gears 83, the loose wire reel 85 is installed on one side of the sliding base 76, and wire ropes 6 are wound on the surfaces of the tight wire reel 84 and the loose wire reel 85.

[0048] While the positioning block 79 slides downward along the direction of the electric slide rail 78, the operator starts the second motor 81. After the second motor 81 starts, it drives the toothed ring 82 to rotate synchronously. While the toothed ring 82 rotates, it meshes with the two groups of the first spur gears 83 to rotate respectively. While the two groups of the first spur gears 83 rotate synchronously, they drive the tight wire reel 84 and the loose wire reel 85 to rotate synchronously respectively. Through the rotation cooperation effect between the tight wire reel 84 and the loose wire reel 85, the line segment of the connection part between the first rack 93 and the wire rope 6 is loosened to adapt to the sliding stroke when the positioning block 79 slides downward along the direction of the electric slide rail 78;

[0049] Subsequently, under the action of the electric slide rail 78, the positioning block 79 first slides upward along the direction of the electric slide rail 78. While the positioning block 79 slides, it drives the laser sensor 710 and the mounting box 91 to slide upward synchronously. While the mounting box 91 slides, it drives the support plate 914 to approach and contact the bottom surface of the steel skeleton frame.

[0050] At the same time, after the second motor 81 starts, it drives the toothed ring 82 to rotate in the reverse direction. While the toothed ring 82 rotates in the reverse direction, it meshes with two groups of first flat gears 83 to rotate in the reverse direction respectively. While the two groups of first flat gears 83 rotate in the reverse direction synchronously, they drive the wire tightening disc 84 and the wire loosening disc 85 to rotate in the reverse direction synchronously respectively. Through the rotation cooperation effect between the wire tightening disc 84 and the wire loosening disc 85, the line segment of the connection part between the first rack 93 and the wire rope 6 is tightened.

[0051] Through the cooperation between the wire tightening disc 84 and the wire loosening disc 85, the winding and unwinding effect of the wire rope 6 is switched, and at the same time, it cooperates with the adjusting assembly 7 to adjust the winding effect of the winding roller 5 to ensure the triggering effect of the wire rope 6 on the locking assembly 9.

[0052] As Figures 7 to 10 shown, the locking assembly 9 includes a mounting box 91. The mounting box 91 is installed at the bottom end of the positioning block 79. A second flat gear 92 is installed at the bottom end of the inner wall of the mounting box 91. A first rack 93 is meshed on one side of the second flat gear 92. One end of the first rack 93 is installed with an elastic telescopic rod 930. The first rack 93 is connected to the inner wall of the mounting box 91 through the elastic telescopic rod 930. The other end of the first rack 93 is connected to the wire rope 6. A screw rod 94 is installed at the top end of the second flat gear 92. A sliding ring 95 is sleeved on the outer surface of the screw rod 94. A first connecting rod 96 is installed on one side of the sliding ring 95. The number of the first connecting rods 96 is set to be multiple groups. The locking assembly 9 further includes two liquid storage barrels 97. The number of the liquid storage barrels 97 is set to be two groups. The bottom inner walls of the two liquid storage barrels 97 are both in contact with a piston disc 98. The bottom end of the part of the piston disc 98 extending out of the liquid storage barrel 97 is connected to one of the multiple groups of first connecting rods 96. The top inner walls of the two liquid storage barrels 97 are both in contact with a push plate 99. The top end of the push plate 99 is connected to a second connecting rod 910. The top end of the second connecting rod 910 is connected to a second rack 911. The locking assembly 9 further includes a pawl 912. The pawl 912 is installed on the inner wall of the mounting box 91. A third flat gear 913 is sleeved on the surface of the extending part of one end of the pawl 912. The third flat gear 913 is meshed with the second rack 911. The top end of one of the multiple groups of first connecting rods 96 is connected to a support plate 914. The support plate 914 is nested and installed on the surface of the mounting box 91. The surface material of the support plate 914 is set to be nitrile rubber.

[0053] While the connection part between the wire rope 6 and the first rack 93 is tightened, the wire rope 6 pulls the first rack 93 to one side. While the first rack 93 slides under force, it drives the elastic telescopic rod 930 to extend. The first rack 93 slides and meshes with the second spur gear 92. Under the sliding action of the first rack 93, the second spur gear 92 produces a rotating effect. While the second spur gear 92 rotates, it drives the screw rod 94 to rotate synchronously. Under the rotating action of the screw rod 94, the sliding ring 95 with a thread sleeved on the surface of the screw rod 94 slides upward along the screw rod 94. While the sliding ring 95 slides, it drives multiple groups of first connecting rods 96 to slide upward. Two of the multiple groups of first connecting rods 96 push the piston disc 98 to slide and squeeze inside the inner cavities of the two liquid storage barrels 97. Under the continuous squeezing action of the piston disc 98, the oil liquid stored in the liquid storage barrel 97 continuously pushes the push plate 99. The push plate 99 slides continuously along the direction of the liquid storage barrel 97 under force. While the push plate 99 slides, it pushes the second rack 911 to slide upward through the second connecting rod 910. While the second rack 911 slides, it meshes with the third spur gear 913. Under the sliding action of the second rack 911, the third spur gear 913 produces a rotating effect. While the third spur gear 913 rotates, it drives the pawl 912 to rotate synchronously. Under the rotating action of the two pawls 912, the top surface of the position of the steel skeleton frame is buckled;

[0054] At the same time, while the remaining one of the multiple groups of first connecting rods 96 slides upward, it pushes the support plate 914, so that the top surface of the support plate 914 is in close contact with the bottom surface of the position of the steel skeleton frame. At the same time, taking advantage of the good wear resistance of nitrile rubber, through the support of the support plate 914 for the bottom of the position of the steel skeleton frame, and at the same time cooperating with the buckling effect of the two pawls 912, the locking of the position of the steel skeleton frame is realized. Subsequently, the hanging plate 1 drives the entire bottom plate 3 of the lifting tool through the sling 2 and hoists the steel skeleton to the construction and installation position.

[0055] By triggering the rotating effect among the second rack 911, the pawl 912 and the third spur gear 913 through the push plate 99 and the second connecting rod 910, the locking effect on the top of the position of the steel skeleton frame is realized. Taking advantage of the good wear resistance of nitrile rubber, the bottom of the position of the steel skeleton frame is closely attached through the support plate 914. At the same time, cooperating with the locking of the two pawls 912 at the top of the position of the steel skeleton frame, at both ends of the position of the steel skeleton frame, through the cooperation between the pawl 912 and the support plate 914, the locking effect on the position of the steel skeleton frame is realized. At the same time, when hoisting the steel skeleton, the contact degree between the position of the steel skeleton frame and the pawl 912 and the support plate 914 is ensured, the stability of the pawl 912 during the hoisting of the steel skeleton is improved. At the same time, cooperating with the left - right balance effect of the adjusting component 7, the stability during the hoisting of the steel skeleton is further improved, and the steel skeleton is prevented from tilting and shaking during hoisting.

[0056] The working principle of the technical solution provided by the present invention is as follows:

[0057] The suspension tray 1 drives the bottom plate 3 of the lifting tool above the steel skeleton through the sling 2. Subsequently, according to the frame width of the steel skeleton, the operator starts the first motor 4. After the first motor 4 starts, it drives the rotating rod 71 to rotate synchronously. After the rotating rod 71 rotates, it drives the input end of the bevel gear set 72 to rotate synchronously. While the input end of the bevel gear set 72 rotates, it meshes with the output end of the bevel gear set 72 to rotate synchronously. While the output end of the bevel gear set 72 rotates, it drives the bidirectional screw 75 to rotate synchronously. Under the rotation of the bidirectional screw 75, the sliding base 76 sleeved on the outer surface of the bidirectional screw 75 slides. While the sliding base 76 slides, it drives the limiting ring 77 at the top to slide along the direction of the limiting rod 30. At the same time, through the relative sliding effect of the two sliding bases 76, while the sliding base 76 slides, it drives the positioning block 79 to slide synchronously through the electric slide rail 78, so that the mounting box 91 at the bottom end of the positioning block 79 reaches the bottom side of the frame position of the steel skeleton;

[0058] Subsequently, the operator starts the electric slide rail 78. Under the action of the electric slide rail 78, the positioning block 79 first slides downward along the direction of the electric slide rail 78. While the positioning block 79 slides, it drives the laser sensor 710 and the mounting box 91 to slide synchronously downward. While the mounting box 91 slides, it drives the support plate 914 to be located at the bottom side of the frame position of the steel skeleton. Subsequently, the first motor 4 drives the rotating rod 71 and the input end of the bevel gear set 72 to rotate synchronously. Under the rotation of the bidirectional screw 75, the two sliding bases 76 continue to slide, so that the mounting box 91 is located at the bottom of the frame position of the steel skeleton;

[0059] During this process, while the rotating rod 71 rotates, it drives the driving wheel 73 to rotate synchronously. While the driving wheel 73 rotates, it contacts the belt in the pulley group 74. Under the rotation of the driving wheel 73, the belt drives the two pulleys in the pulley group 74 to rotate synchronously. While the two pulleys in the pulley group 74 rotate, they drive the two winding rollers 5 to rotate synchronously, so that the wire ropes 6 wound on the surfaces of the two winding rollers 5 are relaxed. By paying out the wire ropes 6 and cooperating with the sliding effect of the sliding base 76 driving the mounting box 91, the adjustment of the distance between the two mounting boxes 91 is realized to adapt to steel skeletons of different widths;

[0060] While the positioning block 79 slides downward along the direction of the electric slide rail 78, the operator starts the second motor 81. After the second motor 81 starts, it drives the toothed ring 82 to rotate synchronously. While the toothed ring 82 rotates, it meshes with the two first spur gears 83 to rotate respectively. While the two first spur gears 83 rotate synchronously, they drive the wire tightening disc 84 and the wire loosening disc 85 to rotate synchronously respectively. Through the rotation cooperation effect between the wire tightening disc 84 and the wire loosening disc 85, the line segment connecting the first rack 93 and the wire rope 6 is relaxed to adapt to the sliding stroke when the positioning block 79 slides downward along the direction of the electric slide rail 78;

[0061] Subsequently, under the action of the electric slide rail 78, the positioning block 79 first slides upward along the direction of the electric slide rail 78. While the positioning block 79 slides, it drives the laser sensor 710 and the mounting box 91 to slide upward synchronously. While the mounting box 91 slides, it drives the support plate 914 to approach and contact the bottom surface of the steel skeleton frame;

[0062] At the same time, after the second motor 81 starts, it drives the toothed ring 82 to rotate in the reverse direction. While the toothed ring 82 rotates in the reverse direction, it meshes with two groups of first flat gears 83 to rotate in the reverse direction respectively. While the two groups of first flat gears 83 rotate synchronously in the reverse direction, they drive the wire tightening disc 84 and the wire loosening disc 85 to rotate synchronously in the reverse direction respectively. Through the rotational cooperation effect between the wire tightening disc 84 and the wire loosening disc 85, the line segment of the connection part between the first rack 93 and the wire rope 6 is tightened;

[0063] While the connection part between the wire rope 6 and the first rack 93 is tightened, the wire rope 6 pulls the first rack 93 to one side. While the first rack 93 slides under force, it drives the elastic telescopic rod 930 to extend. The first rack 93 slides and meshes with the second flat gear 92. Under the sliding action of the first rack 93, the second flat gear 92 produces a rotational effect. While the second flat gear 92 rotates, it drives the screw rod 94 to rotate synchronously. Under the rotational action of the screw rod 94, the sliding ring 95 sleeved on the surface of the screw rod 94 slides upward along the screw rod 94. While the sliding ring 95 slides, it drives multiple groups of first connecting rods 96 to slide upward. Two of the multiple groups of first connecting rods 96 push the piston disc 98 to slide and squeeze inside the inner cavities of the two liquid storage barrels 97. Under the continuous squeezing action of the piston disc 98, the oil liquid stored in the liquid storage barrel 97 continuously pushes the push plate 99. The push plate 99 slides continuously along the direction of the liquid storage barrel 97 under force. While the push plate 99 slides, it drives the second rack 911 to slide upward through the second connecting rod 910. While the second rack 911 slides, it meshes with the third flat gear 913. Under the sliding action of the second rack 911, the third flat gear 913 produces a rotational effect. While the third flat gear 913 rotates, it drives the buckle 912 to rotate synchronously. Under the rotational action of the two buckles 912, the top surface of the steel skeleton frame is buckled;

[0064] At the same time, the remaining one of the multiple groups of first connecting rods 96 slides upward and pushes the support plate 914, so that the top surface of the support plate 914 is in close contact with the bottom surface of the steel skeleton frame. At the same time, taking advantage of the good wear resistance of nitrile rubber, through the support and fitting of the support plate 914 to the bottom of the steel skeleton frame, and cooperating with the buckling effect of the two buckles 912, the locking of the steel skeleton frame is realized. Subsequently, the hanging plate 1 drives the entire bottom plate 3 of the lifting tool through the sling 2 and hoists the steel skeleton to the construction and installation position;

[0065] Meanwhile, during the hoisting process of the steel skeleton, the balance state of the steel skeleton during hoisting is detected through the induction effect between the laser sensors 710 at one end of two groups of positioning blocks 79. Through the sliding fit between the sliding base 76 and the positioning blocks 79, the two groups of mounting boxes 91 are kept in a balanced state, so that the steel skeleton is always in a left-right balanced state during hoisting, avoiding the inclination of the steel skeleton during hoisting, and improving the safety of the steel skeleton during hoisting while improving the hoisting efficiency of the steel skeleton.
