Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a beam lifting equipment that can adjust the position of the lifting point according to the size of the component. Background Technology

[0002] Lifting refers to the installation and positioning of equipment using cranes or hoisting mechanisms. During maintenance or repair, various lifting tools are used to lift equipment, workpieces, tools, materials, etc., causing them to change position.

[0003] Existing hoisting operations, especially when hoisting cube-shaped objects, often result in the hoisting ropes not being perpendicular to the object. This causes the hoisting ropes at both ends of the object to compress it, and the external dimensions of the object are inconsistent. There is an urgent need for an adjustable lifting point beam hoisting device to replace the traditional beam hoisting device that requires multiple specifications. Utility Model Content

[0004] This utility model provides a beam lifting device to solve the problems in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A beam lifting device, comprising:

[0007] The beam has a crossbeam and lifting lugs at both ends. The lifting lugs are used to connect lifting ropes. The upper end of the lifting lugs is used to connect the lifting rope of the crane, and the lower end of the lifting lugs is used to connect the lifting rope of the object being lifted.

[0008] In one specific implementation, the lifting lugs are fixedly welded to both ends of the crossbeam, and at least four sets of the lifting lugs are provided at one end of the crossbeam.

[0009] The lifting ropes used to connect the hoisted object are connected to the lifting lugs at the corresponding lifting points according to the size of the hoisted object.

[0010] In one specific implementation, the lugs are movably fitted onto both ends of the crossbeam rod;

[0011] One end of each crossbeam is connected to a set of lifting lugs.

[0012] In one specific implementation, the two ends of the crossbeam rod are provided with connecting slots for connecting the lifting lugs, the end of the crossbeam rod is provided with a threaded hole, a sealing plug is installed in the threaded hole, the two ends of the crossbeam rod are provided with flat ends, and scale lines are engraved on the flat ends; the sealing plug is provided with spaced raised friction strips.

[0013] In one specific embodiment, the lifting lug includes a collar and a lifting lug plate fixedly welded to the collar. The collar is movably fitted onto both ends of the crossbeam rod, and the lifting lug plate is inserted into the connecting slot.

[0014] In one specific implementation, the thickness of the lug plate matches the width of the connecting slot.

[0015] In one specific implementation, the collar component includes a collar body and locking bolts threaded onto both sides of the collar body, wherein the inner diameter of the collar body matches the diameter of the crossbeam rod.

[0016] The beneficial effects of this utility model are:

[0017] The lifting lugs are located at both ends of the crossbeam. The upper end of the lifting lug is used to connect the lifting rope of the crane, and the lower end of the lifting lug is used to connect the lifting rope of the object being lifted. When lifting the object, the lifting lugs at both ends of the crossbeam can ensure that the lifting rope is in contact with the object and that the lifting rope at both ends of the object will not squeeze the object.

[0031] Reference Figure 1-4 As shown, this utility model provides an adjustable lifting point beam lifting device, including:

[0032] The beam 100 has a lifting lug 200 at both ends. The lifting lug 200 is used to connect the lifting rope. The upper end of the lifting lug 200 is used to connect the lifting rope of the crane, and the lower end of the lifting lug 200 is used to connect the lifting rope of the object being lifted.

[0033] The lifting lugs 200 are set at both ends of the crossbeam 100. The upper end of the lifting lugs 200 is used to connect the lifting rope of the crane, and the lower end of the lifting lugs 200 is used to connect the lifting rope of the object to be lifted. When lifting the object, the lifting lugs 200 at both ends of the crossbeam 100 can ensure that the lifting rope is in contact with the object and that the lifting rope at both ends of the object will not squeeze the object.

[0034] Example 1:

[0035] Reference Figure 1 As shown, the lifting lugs 200 are fixedly welded to both ends of the crossbeam rod 100, and at least four sets of lifting lugs 200 are provided at one end of the crossbeam rod 100.

[0036] The lifting ropes used to connect the hoisted object are connected to the lifting lugs 200 at the corresponding lifting points according to the size of the hoisted object.

[0037] For example, when hoisting a 3m cube-shaped fragile object, the four points of the hoisting rope must be vertical and not press down on the fragile object. Starting from the middle of the crossbeam 100, divide it to both sides and find the hoisting lugs 200 that are more than 1.5m long on both sides. Two hoisting ropes can be attached to each of the two symmetrical hoisting points on the left and right sides.

[0038] Example 2:

[0039] Reference Figure 2-4 As shown, the lug 200 is movably connected to both ends of the crossbeam 100;

[0040] One end of the crossbeam 100 is connected to a set of lifting lugs 200.

[0041] As a further preferred embodiment of the above, the two ends of the crossbeam 100 are provided with connecting slots 101 for connecting the lifting lugs 200, and the end of the crossbeam 100 is provided with a threaded hole 102. A sealing plug 103 (with spaced protruding friction strips 1031 on the sealing plug for easy use) is installed in the threaded hole 102. The two ends of the crossbeam 100 are provided with flat ends 104, and scale lines 105 are engraved on the flat ends 104. The scale lines 105 can be used to observe the movement adjustment distance of the lifting lugs 200.

[0042] As a further preferred embodiment of the above, the lifting lug 200 includes a collar 210 and a lifting lug plate 220 fixedly welded to the collar 210. The collar 210 is movably fitted onto both ends of the crossbeam 100, and the lifting lug plate 220 is inserted into the connecting slot 101. The insertion of the lifting lug plate 220 into the connecting slot 101 can prevent the collar 210 from rotating.

[0043] Furthermore, the thickness of the lug plate 220 matches the width of the groove in the connecting slot 101.

[0044] Furthermore, the collar component 210 includes a collar body 211 and locking bolts 212 threadedly installed on both sides of the collar body 211. The inner diameter of the collar body 211 matches the diameter of the crossbeam rod 100. When the locking bolts 212 are tightened, one end of the locking bolts 212 contacts the flat end 104 for fixation.

[0045] For example, when hoisting a 3m cube-shaped fragile component, the collar 210 is moved so that the collars 210 at both ends of the crossbeam 100 are located 1.5m on both sides, and the position is fixed by tightening the locking bolts 212.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
