[0034] Example

[0035] like Figure 1 As shown, the utility model proposes a lifting tool for steel beam docking, including a hanging plate 1, a balancing assembly 2 that drives the hanging plate 1 to maintain horizontality, and the balancing assembly 2 is installed on the top of the hanging plate 1. The balancing assembly 2 includes two groups of fixed plates 21 fixedly connected to the top of the hanging plate 1, and the position of the fixed plate 21 is fixed. A fixed rod 22 is fixedly connected between the two groups of fixed plates 21, and the position of the fixed rod 22 is also fixed. The outer ring sliding sleeve of the fixed rod 22 is provided with at least two groups of rotating plates 23, and the tops of the multiple groups of rotating plates 23 are commonly fixedly connected with a top plate 24. The top plate 24 can rotate with the fixed rod 22 as the axis through the setting of the rotating plate 23, so that the hanging plate 1 can always be perpendicular to the ground under the influence of gravity, so that the steel beam can be kept horizontal after being lifted. Two groups of lifting blocks 25 are also installed on the top of the top plate 24, and lifting holes are opened in the lifting blocks 25, so that the steel cable can pass through the lifting blocks 25 to lift the lifting tool as a whole, so as to achieve the purpose of lifting the steel beam.

[0036] For further information, see Figure 2 and Figure 3The above-mentioned lifting tool includes a docking mechanism 3 for driving the steel beams to approach each other, and the docking mechanism 3 is installed at the bottom of the hanging plate 1. The docking mechanism 3 includes two groups of first mounting plates 31 fixedly connected to the bottom of the hanging plate 1, and the position of the first mounting plates 31 is fixed. A first bidirectional threaded rod 32 is rotatably connected between the two groups of first mounting plates 31, and the first bidirectional threaded rod 32 rotates in place. A bearing seat installed at the bottom of the hanging plate 1 is also provided in the middle position of the first bidirectional threaded rod 32, which is used to position and support the first bidirectional threaded rod 32. The thread directions of the two ends of the first bidirectional threaded rod 32 are opposite, and two groups of first moving blocks 33 are threadedly connected to the first bidirectional threaded rod 32. When the first bidirectional threaded rod 32 rotates, it drives the first moving block 33 to move along the length direction of the first bidirectional threaded rod 32, and at the same time, the two groups of first moving blocks 33 approach each other or move away from each other when moving synchronously. A moving plate 34 is fixedly connected to the bottom of the first moving block 33, and the moving plate 34 moves synchronously with the limit sleeve 35. Two groups of limit sleeves 35 are installed on both sides of the moving plate 34, and the limit sleeves 35 also move synchronously with the moving plate 34. The limit sleeves 35 are slidably connected with limit rods 36, and the limit rods 36 are used to limit the limit sleeves 35 when they move, so that the limit sleeves 35 can only move along the length direction of the limit rods 36, so that the movement of the moving plate 34 is stable. The two ends of the limit rods 36 are respectively fixedly connected to the two groups of first mounting plates 31, and the position of the limit rods 36 is fixed. A first servo motor 37 is installed on one side of a group of first mounting plates 31 away from the first bidirectional threaded rod 32, and the output end of the first servo motor 37 passes through the first mounting plate 31 and is fixedly connected to the first bidirectional threaded rod 32. The first servo motor 37 is used to drive the first bidirectional threaded rod 32 to rotate after starting, thereby driving the two groups of first moving blocks 33 to move closer to or away from each other. A counterweight block 38 is also installed on the side of the other group of first mounting plates 31 away from the first bidirectional threaded rod 32, and the counterweight block 38 is used to keep the center of gravity balanced.

[0037] Furthermore, if Figure 3 and Figure 4As shown, the above-mentioned lifting tool also includes a fixing component 4 for clamping the steel beam, and the fixing component 4 is arranged on the docking mechanism 3. The fixing component 4 includes four groups of slide grooves 41 opened in the moving plate 34, and the four groups of slide grooves 41 are evenly distributed on both sides of the first moving block 33. Each group of slide grooves 41 is slidably connected with a slider 42, and the slider 42 slides smoothly in the slide groove 41. A positioning plate 43 is fixedly connected to the bottom of the slider 42, and the positioning plate 43 moves synchronously with the slider 42. The positioning plate 43 is L-shaped, which is convenient for clamping and supporting the steel beam. An anti-skid pad 44 is also installed on the side where the two groups of positioning plates 43 are close to each other. The anti-skid pad 44 is made of rubber material and is used to increase friction and prevent the steel beam from sliding after being fixed. The fixing component 4 also includes a second mounting plate 45 fixedly connected to the top of the limiting sleeve 35, and the position of the second mounting plate 45 is fixed. A second bidirectional threaded rod 46 is rotatably connected between the two groups of second mounting plates 45, and the second bidirectional threaded rod 46 rotates in place. The thread directions of the two ends of the second bidirectional threaded rod 46 are opposite. Two groups of second moving blocks 47 are threadedly connected to the second bidirectional threaded rod 46. When the second bidirectional threaded rod 46 rotates, the second moving block 47 is driven to move along the length direction of the second bidirectional threaded rod 46, and the moving directions of the two groups of second moving blocks 47 are opposite, that is, they are close to each other or away from each other. The two groups of second moving blocks 47 are respectively fixedly connected to a group of sliders 42 below, and are used to drive the sliders 42 to move synchronously when the second moving block 47 moves. A group of second servo motors 48 are respectively arranged on both sides of the first moving block 33. The second servo motor 48 is installed on the side of the second mounting plate 45 away from the second bidirectional threaded rod 46. The output end of the second servo motor 48 passes through the second mounting plate 45 and is fixedly connected to the second bidirectional threaded rod 46. The second servo motor 48 is used to drive the second bidirectional threaded rod 46 to rotate. The two groups of second servo motors 48 are symmetrically arranged with the first moving block 33 as the center, and are used to balance the weight and prevent tilting.

[0038] In this embodiment, first, the steel cable is passed through the hoisting hole provided on the hoist block 25, and the whole is hoisted. After moving it to the steel beam, multiple groups of second servo motors 48 are started to drive the second bidirectional threaded rod 46 to rotate, and the second bidirectional threaded rod 46 drives the second moving block 47 to move along the length direction of the second bidirectional threaded rod 46 when rotating. Since the thread directions at both ends of the second bidirectional threaded rod 46 are opposite, when the second bidirectional threaded rod 46 rotates, the two groups of second moving blocks 47 can be driven to approach each other, thereby driving the two groups of positioning plates 43 to approach each other through the slider 42 to clamp the steel beam, and the setting of the anti-skid pad 44 prevents the steel beam from sliding easily. The steel beam is hoisted to the specified position. Since the rotating plate 23 is rotatably connected to the fixed rod 22, the steel beam can be kept in a horizontal state during the hoisting process. Then the first servo motor 37 is started, and the first servo motor 37 drives the first bidirectional threaded rod 32 to rotate in place. Since the first moving block 33 is threadedly connected to the first bidirectional threaded rod 32, and the threads at both ends of the first bidirectional threaded rod 32 are in opposite directions, the first bidirectional threaded rod 32 can drive the two groups of first moving blocks 33 to approach each other when rotating, so that the two groups of moving plates 34 are approached to each other. When the moving plate 34 moves, the limiting sleeve 35 is driven to move synchronously, and the limiting sleeve 35 is slidably connected to the fixed limiting rod 36, so that the moving plate 34 moves smoothly under the limiting action of the limiting sleeve 35 and the limiting rod 36, so that the two groups of steel beams can approach each other for easy docking.

[0039] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
