cylindrical cross-shaped lifting beam

Abstract

This utility model discloses a cylindrical cross-shaped lifting beam, comprising: a long crossbeam, with upper lifting lugs welded to both ends of the long crossbeam, and two upper shackles respectively installed in the upper lifting lugs at both ends of the long crossbeam; cantilever beams welded to the left and right sides of the middle of the long crossbeam, with several lower lifting lugs welded to the lower surface of each cantilever beam, and two lower shackles and two steel plate clamps respectively installed on the lower lifting lugs of the two cantilever beams. The two steel plate clamps are used to hook the top ends of the cylinder. The distance between the two steel plate clamps can be adjusted by installing them on different lower lifting lugs to accommodate cylinders of different lengths. The described cylindrical cross-shaped lifting beam has a simple structure, low cost, and can increase the overall lifting capacity, allowing two overhead cranes to lift the cylinder; thus eliminating the need to rent large cranes to lift heavy cylinders, greatly saving equipment costs.

Description

Technical Field

[0001] This utility model relates to the field of cryogenic high-pressure vessel manufacturing, specifically to a cylindrical cross-shaped lifting beam. Background Technology

[0002] As pressure vessel diameters increase and shell plates thicken, the weight of individual shell sections becomes increasingly heavier. The overhead cranes in the existing workshop typically have a fixed lifting capacity, which may be less than the weight of a single shell section, making it insufficient for lifting such sections. Therefore, a lifting beam capable of connecting two overhead cranes simultaneously needs to be designed to increase the overall lifting capacity, thereby enabling the lifting of excessively heavy single shell sections. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cylindrical cross lifting beam that can connect two cranes at the same time for lifting heavy single-section cylindrical bodies.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a cylindrical cross-shaped lifting beam, characterized in that it includes: a long crossbeam, with upper lifting lugs welded to the upper ends of the long crossbeam, and two upper shackles respectively installed in the upper lifting lugs at both ends of the long crossbeam. The hooks of two cranes can lift the long crossbeam by hooking into the two upper shackles respectively. A horizontally arranged cantilever beam perpendicular to the long crossbeam is welded to the left and right sides of the middle of the long crossbeam. The two cantilever beams are aligned left and right. Several lower lifting lugs are welded to the lower surface of each cantilever beam, arranged at intervals along the left and right sides of the cantilever beam. Two lower shackles and two steel plate clamps are also provided. The two lower shackles are respectively installed on the lower lifting lugs of the two cantilever beams. The positions of the two lower shackles are symmetrical about the long crossbeam. The two steel plate clamps are respectively installed on the two lower shackles. The two steel plate clamps are used to hook the top ends of the cylinder. The distance between the two steel plate clamps can be adjusted by installing the two lower shackles on different lower lifting lugs so as to adapt to cylinders of different lengths.

[0005] Furthermore, in the aforementioned cylindrical cross-shaped lifting beam, two upper lifting lugs are welded to the top of each end of the long cross beam.

[0006] Furthermore, in the aforementioned cylindrical cross-shaped lifting beam, both the long crossbeam and the cantilever beam are made by welding reinforcing ribs onto I-beams.

[0007] Furthermore, in the aforementioned cylindrical cross-beam, a large-span vertical plate reinforcing rib is welded to the top surface of the long horizontal beam, and reinforcing plates are also welded to both sides of the large-span vertical plate reinforcing rib for reinforcement.

[0008] Furthermore, in the aforementioned cylindrical cross-beam, a central lifting lug is welded above the middle of the long crossbeam to facilitate lifting by a single overhead crane.

[0009] The advantages of this utility model are: the cylindrical cross-beam structure is simple and low in cost, and can increase the overall lifting capacity, which can meet the lifting capacity of two overhead cranes; thus, there is no need to rent large cranes to lift heavy-duty cylinders, which greatly saves equipment costs. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the cylindrical cross-shaped lifting beam described in this utility model. Detailed Implementation

[0011] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0012] like Figure 1 As shown, the cylindrical cross-shaped lifting beam includes: a long crossbeam 1, with upper lifting lugs 2 welded to the top of both ends of the long crossbeam 1, and two upper shackles 3, which are respectively installed in the upper lifting lugs 2 at both ends of the long crossbeam 1. The hooks of two cranes can lift the long crossbeam 1 by hooking into the two upper shackles 3 respectively. A horizontally arranged cantilever beam 4, perpendicular to the long crossbeam 1, is welded to the left and right sides of the middle of the long crossbeam 1. The two cantilever beams 4 are aligned left and right, and several [unclear - possibly referring to a specific feature or design] are welded to the lower surface of each cantilever beam 4. The lower lifting lugs 5 are arranged at intervals along the left and right sides of the cantilever beam 4. There are also two lower shackles 6 and two steel plate clamps 7. The two lower shackles 6 are respectively installed on the lower lifting lugs 5 of the two cantilever beams 4. The positions of the two lower shackles 6 are symmetrical about the long crossbeam 1. The two steel plate clamps 7 are respectively installed on the two lower shackles 6. The two steel plate clamps 7 are used to hook the top two ends of the cylinder 8. The distance between the two steel plate clamps 7 can be adjusted by installing the two lower lifting lugs 5 on different lower lifting lugs so as to accommodate cylinders 8 of different lengths.

[0013] In this embodiment, two upper lifting lugs 2 are welded to the top of each end of the long crossbeam 1, with an extra upper lifting lug on each side for backup. Both the long crossbeam 1 and the cantilever beam 4 are made by welding reinforcing ribs onto I-beams. A large-span vertical plate reinforcing rib 9 is welded to the top surface of the long crossbeam 1, and reinforcing plates 10 are welded to both sides of the large-span vertical plate reinforcing rib 9 for reinforcement. This arrangement makes the cross-shaped lifting beam more reliable.

[0014] A central lifting lug 11 is welded above the middle of the long cross beam 1 to facilitate the lifting of the entire cross beam by a single crane. The crane can easily lift the entire cross beam through the central lifting lug 11, thus facilitating the transfer of the beam.

[0015] During operation, the hooks of the two overhead cranes are hooked into the two upper shackles 3 respectively. Then, the two overhead cranes lift the cross beam, and then move the cross beam above the cylinder. Then, the height of the cross beam is lowered. Then, the two steel plate clamps 7 are hooked onto the top two ends of the cylinder 8 respectively. Then, the two overhead cranes lift the cylinder 8 simultaneously.
