TECHNICAL FIELD
[0001] The present application relates to the technical field of lifting devices, in particular to a telescopic steel beam embracing type lifting device. BACKGROUND
[0002] In the petrochemical plant, the device site cannot be fired frequently, and when there is no lifting point above the device area equipment, the maintenance operation cannot be carried out. The existing lifting device cannot meet the lifting requirements and cannot reach the center of the lifting point, resulting in increased operation difficulty. CONTENT OF THE UTILITY MODEL
[0003] In order to make up for the above shortcomings, the present application provides a telescopic steel beam embracing type lifting device, which aims to improve the problems mentioned in the above background technology.
[0004] The telescopic steel beam embracing type lifting device provided by the embodiments of the present application comprises a load-bearing rod and an L-shaped fixing rod, the upper end of the fixing rod is hingedly connected to one end of the load-bearing rod, the other end of the load-bearing rod is hingedly connected with a holding rod, the lower end of the holding rod is detachably connected with the lower end of the fixing rod, a steel beam in the shape of an I-beam is embraced between the load-bearing rod, the fixing rod and the holding rod, and a lifting hole is arranged on the load-bearing rod.
[0005] In a specific embodiment, the lifting holes are arranged in an axial array along the load-bearing rod.
[0006] In the implementation process described above, large petrochemical equipment usually has a lifting point and is adapted to its own center of gravity. When the equipment is hoisted into place, pipes, valves or other small additional equipment are connected to the equipment, and steel beams are welded to form a frame to reinforce these accessories, resulting in a change in the center of gravity. At this time, the original lifting point cannot meet the changed center of gravity, and it is necessary to reinstall the lifting point. However, the petrochemical equipment area cannot be fired to weld a new lifting point. At this time, the steel beam in the form of a net is the best choice for installing the lifting device. After the lifting device is installed, one of the lifting holes is selected for trial lifting to determine whether it corresponds to the center of gravity, so as to adjust to the appropriate lifting hole.
[0007] In a specific embodiment, an extension rod is telescopically connected in the load-bearing rod, and a lifting ring is screwed to the outer end of the extension rod.
[0008] In the implementation process described above, the extension rod can extend the lifting point outward by a certain distance to better adjust the lifting center. The extension rod can also be retracted into the load-bearing rod for storage. If the lifting ring still cannot meet the lifting balance after the extension rod is fully extended, the lifting device cannot meet the current lifting conditions. Because the extension rod is excessively elongated, the steel beam may not be able to withstand the torque.
[0009] In a specific embodiment, limit plates are arranged at both ends of the extension rod, and threaded holes adapted to the lifting ring are formed at both ends of the extension rod.
[0010] In the implementation process, the extension rod can be extended left and right, so as to quickly adjust the lifting point position.
[0011] In a specific embodiment, the load-bearing rod is inserted with a pin rod, and the extension rod is arrayed with a pin hole matched with the pin rod.
[0012] In the implementation process, the pin rod is inserted through the extension rod and the load-bearing rod, so as to lock the extension rod.
[0013] In a specific embodiment, the outer end of the pin rod is inserted with an open pin, and the open pin is magnetically connected with the pin rod.
[0014] In the implementation process, the L-shaped open pin is inserted into the outer end of the pin rod, and the open pin is magnetically connected with the pin rod, so as to avoid the disconnection of the pin rod.
[0015] In a specific embodiment, the fixed rod is fixedly connected with a support block, and the support block is inserted into one side of the steel beam.
[0016] In the implementation process, when the lifting tool embraces the steel beam and lifts, the steel beam will be twisted and deformed when the lifting point is at the center of the steel beam. The support block is inserted into the steel beam to improve the strength of the embraced steel beam, thereby reducing the deformation.
[0017] In a specific embodiment, the lower end of the embracing rod is screwed with a screw, and the screw is pinned with the fixed rod.
[0018] In the implementation process, after embracing the steel beam, the screw is inserted through the fixed rod and the embracing rod, and the fixed rod and the embracing rod are fixedly connected together, thereby realizing the detachable function.
[0019] In a specific embodiment, the embracing rod is telescopically connected with a plug block, the upper and lower surfaces of the plug block have a certain taper, and the plug block is movably inserted into the other side of the steel beam.
[0020] In a specific embodiment, the plug block is rotatably connected with a screw rod, the screw rod is threadedly connected with the embracing rod, and the outer end of the screw rod is provided with a rotating rod.
[0021] In the implementation process, the rotating rod is rotated to drive the screw rod to rotate, and the plug block is pushed out and expanded on the other side of the steel beam, which has the same effect as the support block of improving the strength of the steel beam at the high embracing point.
[0022] Compared with the prior art, the beneficial effects of the present application are that the load-bearing rod, the fixed rod and the embracing rod embrace the specific position on the steel beam to form a new lifting point, so that the plumb line of the lifting point is closer to the center of gravity of the equipment, the operation is simple, and the case of fire in the petrochemical equipment area is avoided.

The lower end of the embracing rod 30 is detachably connected with the lower end of the fixed rod 20. A steel beam 40 in the shape of an I-beam is embraced between the load-bearing rod 10, the fixed rod 20 and the embracing rod 30. The load-bearing rod 10 is provided with a lifting hole 11. The load-bearing rod 10, the fixed rod 20 and the embracing rod 30 are embraced at specific positions on the steel beam 40 to form a new lifting point, so that the plumb line of the lifting point is closer to the center of gravity of the equipment, and the operation is simple, avoiding the case of fire in the petrochemical equipment area.
[0031] Please refer to Figures 1-4 , the lifting holes 11 are arranged in the axial direction of the load-bearing rod 10. After the hoist is assembled, one of the lifting holes 11 is selected for trial lifting to determine whether it corresponds to the center of gravity, so as to adjust to the appropriate lifting hole 11.
[0032] Please refer to Figures 1-4The extension rod 50 is telescopic connected in the load bearing rod 10, and the outer end of the extension rod 50 is screwed with a lifting ring 51. The extension rod 50 can extend the lifting point outward a little bit to better adjust the lifting center, or can be retracted in the load bearing rod 10 to be stored. If the lifting ring 51 cannot meet the lifting balance after the extension rod 50 is maximally extended, the lifting device cannot meet the current lifting condition, because the extension rod 50 is excessively elongated, and the steel beam 40 can not be able to bear the torque.
[0033] Please refer to Figures 1-4 The extension rod 50 is telescopic connected in the load bearing rod 10, and the outer end of the extension rod 50 is screwed with a lifting ring 51. The extension rod 50 can extend the lifting point outward a little bit to better adjust the lifting center, or can be retracted in the load bearing rod 10 to be stored. If the lifting ring 51 cannot meet the lifting balance after the extension rod 50 is maximally extended, the lifting device cannot meet the current lifting condition, because the extension rod 50 is excessively elongated, and the steel beam 40 can not be able to bear the torque.
[0034] Please refer to Figures 1-4 The load bearing rod 10 is inserted with a pin rod 53, and the extension rod 50 is arrayed with pin holes matched with the pin rod 53. The pin rod 53 penetrates the extension rod 50 and the load bearing rod 10 to lock the extension rod 50.
