[0001] This utility model relates to the field of flat beam technology, and specifically to a combined flat beam with adjustable length. Background Technology

[0002] For the hoisting of some ultra-long and ultra-large components, a spreader beam is often required. The spreader beam can reduce the direct compression and friction damage of the slings to precision equipment or easily deformable components, and prevent the bending deformation or cracking of long-span components (such as ultra-long steel structure beams) due to excessive cantilever length.

[0003] The hoisting of components of different sizes requires different lengths of the spreader beam, so it is essential to design an adjustable spreader beam. Utility Model Content

[0005] The technical solution to achieve the above objectives is:

[0006] This utility model provides a length-adjustable combined spreader beam, comprising: at least one standard unit, the number of standard units being selected according to the length of the component to be hoisted; when there are two or more standard units, the ends of adjacent standard units are connected, and the overall length of the connected standard units is adapted to the length of the component; two lifting lug assemblies for hoisting on a hoisting device, respectively located at both ends of the standard unit; when there are multiple standard units, the two lifting lug assemblies are respectively located at both ends of the overall structure formed after the standard units are connected; an adjustable component located between the corresponding lifting lug assembly and the corresponding standard unit, for adjusting the distance between the lifting lug assembly and the standard unit; and two hoisting ropes, respectively hinged to the corresponding lifting lug assembly, for hoisting the component.

[0007] Furthermore, the standard unit includes: a crossbeam; two first flanges, respectively fixed at both ends of the crossbeam; and a plurality of first stiffening ribs, spaced apart around the first flanges and fixed at the connection between the first flanges and the crossbeam.

[0008] Furthermore, the lifting lug assembly includes: a support plate; a second flange fixed to a corresponding end of the support plate; and a plurality of second stiffening ribs spaced around the second flange and fixed at the connection between the second flange and the support plate.

[0009] Furthermore, the first flanges at corresponding ends of adjacent standard units abut against each other and are fixed with bolts; the first flange of the corresponding standard unit abuts against the second flange of the corresponding lifting lug assembly and is fixed with bolts.

[0010] Furthermore, the adjustable component includes several threaded screws, the two ends of which are respectively inserted into the first flange of the corresponding standard unit and the second flange of the corresponding lifting lug assembly, and the several threaded screws are spaced apart, with a length equal to the length of the standard unit.

[0011] Furthermore, the through screw is staggered from the first stiffening rib and the second stiffening rib.

[0012] Furthermore, the adjustable component also includes at least one reinforcing ring, on which several through holes are formed, and the through screw is inserted into the through holes.

[0013] Furthermore, the lifting lug assembly also includes: a hinge plate hinged to one end of the support plate away from the second flange; a second lifting ring hinged to the lower end of the hinge plate; and a third lifting ring sleeved on the second lifting ring, wherein the end of the lifting rope is provided with an annular knot, and the annular knot is sleeved on the third lifting ring.

[0014] Furthermore, the third lifting ring has two rings, and both ends of the lifting rope are provided with a loop knot. The two loop knots are respectively fitted onto the corresponding third lifting ring, so that the lifting rope as a whole forms a closed loop for fitting onto the component.

[0015] Furthermore, the lifting lug assembly also includes a first lifting ring hinged to the upper end of the hinge plate for mounting on the lifting equipment.

[0017] By setting up standard units, installing lifting lug assemblies at both ends of the standard units, and adjusting the number of standard units according to the length of the components to be lifted, the overall length of the spreader beam is made closer to the length of the components.

[0018] An adjustable component is provided between the corresponding end of the standard unit and the corresponding lifting lug assembly. The adjustable component includes several threaded screws. By stretching or pushing, the distance between the lifting lug assembly and the standard unit can be adjusted, thereby enabling fine-tuning of the length of the spreader beam, so that the length of the spreader beam is more suitable for the components to be lifted.

[0024] See Figure 1 This invention provides a modular, adjustable-length spreader beam, solving the problem that existing spreader beams have a single length and can only accommodate components of one size. By setting standard units with lifting lugs at both ends, and adjusting the number of standard units according to the length of the component to be lifted, the overall length of the spreader beam becomes closer to the length of the component. An adjustable component, including several threaded rods, is installed between the corresponding end of each standard unit and the corresponding lifting lug. This adjustable component allows for adjustment of the distance between the lifting lug and the standard unit by stretching or pushing, enabling fine-tuning of the spreader beam's length to better suit the components to be lifted.

[0025] The following description, in conjunction with the accompanying drawings, describes a modular spreader beam with adjustable length according to this utility model.

[0026] See Figure 1 This diagram illustrates the usage of the adjustable-length combined spreader beam of this invention. (See attached diagram.) Figure 2 This diagram shows the overall structure of the adjustable-length combined spreader beam of this utility model. (See attached diagram.) Figure 3 The diagram below shows a schematic of the adjustable combined spreader beam assembly of this utility model after shortening. Figures 1 to 3 This invention describes a combined spreader beam with adjustable length.

[0027] like Figures 1 to 3As shown, this utility model discloses a length-adjustable combined spreader beam, comprising: at least one standard unit 2, the number of standard units 2 being selected according to the length of the component to be hoisted; when there are two or more standard units 2, the ends of adjacent standard units 2 are connected, and the overall length of the connected standard units 2 is adapted to the length of the component; two lifting lug assemblies 4, used for hoisting on the hoisting equipment 1, respectively located at both ends of the standard unit 2; when there are multiple standard units 2, the two lifting lug assemblies 4 are respectively located at both ends of the overall structure formed after the standard units 2 are connected; an adjustable component 3, located between the corresponding lifting lug assembly 4 and the corresponding standard unit 2, used for adjusting the distance between the lifting lug assembly 4 and the standard unit 2; and two hoisting ropes 5, respectively hinged to the corresponding lifting lug assembly 4, used for hoisting the component.

[0028] Specifically, a corresponding number of standard units 2 are selected according to the length of the component, so that the overall length of the spreader beam is approximately the length of the component. Then, the length of the spreader beam is finely adjusted by the adjustable component 3 so that the length of the spreader beam is more in line with the component to be hoisted.

[0029] In one specific embodiment, the standard unit 2 includes: a crossbeam 21; two first flanges 22, respectively fixed at both ends of the crossbeam 21; and a plurality of first stiffening ribs 23, spaced apart around the first flanges 22, and fixed at the connection between the first flanges 22 and the crossbeam 21.

[0032] In one specific embodiment, the first flanges 22 at corresponding ends of adjacent standard units 2 abut against each other and are fixed by bolts; the first flanges 22 of the corresponding standard unit 2 abut against the second flanges 42 of the corresponding lifting lug assembly 4 and are fixed by bolts.

[0033] In one specific embodiment, the adjustable component 3 includes a plurality of threaded screws 31, the two ends of which are respectively inserted into the first flange 22 of the corresponding standard unit 2 and the second flange 42 of the corresponding lifting lug component 4, and the plurality of threaded screws 31 are spaced apart, with a length equal to the length of the standard unit 2.

[0034] In one specific embodiment, the through screw 31 is staggered from the first stiffening rib 23 and the second stiffening rib 43.

[0035] Specifically, the length of the threaded rod 31 is 1m. Each threaded rod 31 has at least four nuts threaded onto it, two of which are located on both sides of the first flange 22, and the other two are located on both sides of the second flange 42. By setting nuts on the threaded rod 31, the threaded rod 31 is fixed to the first flange 22 and the second flange 42, thereby preventing relative slippage during use and avoiding construction accidents.

[0036] In one specific embodiment, the adjustable component 3 further includes at least one reinforcing ring 32, the reinforcing ring 32 having a plurality of through holes, and the through screw 31 passing through the through holes.

[0038] Preferably, the lifting rope 5 is equipped with a limiting member, the two ends of which are slidably connected to the lifting rope 5, forming a closed ring structure on the lifting rope 5. This allows the component to be inserted into the ring structure, and by adjusting the position of the limiting member, the component can be fixed in place, thus preventing the component from falling off the lifting rope 5. The lifting rope 5 is also equipped with a rubber padding layer to cushion the component and prevent damage to it.

[0039] In one specific embodiment, there are two third lifting rings 47, and both ends of the lifting rope 5 are provided with a ring knot. The two ring knots are respectively sleeved on the corresponding third lifting rings 47, so that the lifting rope 5 is a closed ring for being sleeved on the component.

[0040] In one specific embodiment, the lifting lug assembly 4 further includes a first lifting ring 45 hinged to the upper end of the hinge plate 44 for mounting on the lifting equipment 1.

[0041] In a preferred embodiment, the first lifting ring 45, the second lifting ring 46 and the third lifting ring 47 are all ring structures with notches. The notches are provided with fixed ends, and the two fixed ends are connected by bolts to seal the notches. The bolts of the first lifting ring 45 and the second lifting ring 46 are inserted into the hinge plate 44.

[0042] The following is a detailed description of the use of the adjustable-length combined spreader beam of this utility model.

[0043] First, select the corresponding number of standard units 2 according to the length of the component to be hoisted and splice and fix them. Then, stretch or push the corresponding lifting lug assembly 4 so that the corresponding lifting lug assembly 4 moves away from or closer to the standard unit 2 along the axis of the threaded rod 31, thereby making a fine adjustment to the overall length of the spreader beam to better fit the spreader beam. Then, tighten the nut on the threaded rod 31 to fix the standard unit 2 and the lifting lug assembly 4.

[0044] Then, the first lifting ring 45 of the lifting lug assembly 4 is installed on the lifting equipment 1, the component to be lifted is installed on the lifting rope 5, and then the component is lifted.
