Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting assistance, and in particular relates to a hoisting balance beam. Background Art

[0002] Lifting is a common engineering operation, which mainly involves the use of various lifting machinery (such as cranes, hoists, tower cranes, etc.) to move, lift or lower heavy objects. Lifting plays an important role in the construction, manufacturing, logistics, warehousing and other industries, and is a key link in achieving efficient and safe production. Accurately calculating the load weight, selecting appropriate lifting machinery and slings, determining the appropriate lifting point, and avoiding the swing or tilt of the heavy object caused by improper lifting points are the technical points that need to be paid attention to in lifting operations;

[0003] After checking, the publication (announcement) number: CN207121351U discloses a lifting balance beam, which discloses "including a main beam with a cavity inside, two sliders slidably connected in the main beam, and a latch assembly fixing the sliders at a fixed position on the main beam; it has the technical effect of making the balance beam more solid";

[0004] However, when this type of balance beam is used, because the hanging ring is at the center of the balance beam, most of the objects being lifted are often irregular in size and the center of gravity is difficult to determine during lifting operations. Especially for large objects, it is difficult to determine the appropriate lifting point. Lifting directly with a crane hook alone can easily cause the object to swing or tilt. During the lifting process, it is difficult to maintain a steady speed and direction, increasing safety risks.

[0005] In order to solve the above problems, a lifting balance beam is proposed in the present application. Utility Model Content

[0027] A lifting balance beam comprises a balance beam body 1;

[0028] In this implementation scheme: After checking the public (announcement) number: CN207121351U discloses a lifting balance beam, in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when this balance beam is in use, because the hanging ring is in the center of the balance beam, in the lifting operation, most of the lifting objects are often irregular in size and the center of gravity is difficult to determine. Especially for objects with larger sizes, it is difficult to determine the appropriate lifting point. Lifting directly with a crane hook alone can easily cause the heavy object to swing or tilt. During the lifting process, it is difficult to maintain a steady speed and direction, increasing the safety risk." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a balance component 2 and a moving component 3 are added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 5 As shown;

[0031] Combining the above:

[0032] In order to ensure balance when lifting heavy objects, the lifting balance beam also includes a balance component 2 arranged on the surface of the balance beam body 1;

[0033] The balancing assembly 2 includes two lifting rings 21 symmetrically fixedly connected to the surface of the balancing beam body 1, and two positioning blocks 22 are symmetrically slidably connected to the surface of the balancing beam body 1. A through hole is provided on the surface of each positioning block 22, and a plurality of positioning holes 24 are evenly provided on the surface of the balancing beam body 1. Locking screws 23 are provided inside the positioning holes 24, and both ends of the locking screws 23 penetrate the surface of the positioning blocks 22 through the through holes. A limiting groove is provided at one end of each positioning block 22 away from the lifting ring 21, and a hook 25 is provided inside each limiting groove. The hook 25 is slidably connected to the positioning block 22 through the limiting groove.

[0034] In this embodiment: when it is necessary to lift heavy objects, the operator passes the lifting cable through the inside of the two lifting rings 21 and fixes it, slides the two positioning blocks 22 on the surface of the balance beam body 1 until the distance between the two positioning blocks 22 is adjusted to be balanced, then passes the locking screw 23 through the positioning hole 24 through the through hole and fixes it with a nut to lock the two positioning blocks 22, and hangs the heavy objects on the surfaces of the two hooks 25, so that the heavy objects can be lifted and balance can be achieved when lifting the heavy objects.

A positioning groove 210 is opened inside the limiting plate 26, and the limiting plate 26 is inserted into the interior of the positioning groove 210.

[0037] In this embodiment, after the hook lock of the heavy object is hung inside the hook 25, the heavy object will pull the hook 25 downward, and the positioning rod 29 will be inserted into the positioning groove 210 to lock the limit plate 26 to prevent it from being unhooked when the heavy object is lifted.

[0038] Going further:
