AI Technical Summary
Existing lifting equipment is inefficient and cumbersome when lifting chemical barrels, which increases the time workers spend in close contact with harmful chemicals. The risk is especially increased when lifting multiple barrels.
A sling structure including a lifting ring, a rotating shaft, a limiter, a load-bearing rod and a telescopic beam is designed. The limiter can adjust the length and has a built-in spring. The boom spacing can be quickly positioned by rotating the rotating shaft and adjusting the limiter length, achieving efficient and accurate lifting.
It improves the efficiency and accuracy of lifting the same items and reduces the operating risks for workers, especially when lifting multiple chemical barrels, which reduces the time of close contact with harmful agents.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of slings, and in particular relates to a sling that is convenient to use. Background Art
[0002] Hoisting equipment is widely used in production. In chemical mineral processing, it involves the lifting and transportation of chemical barrels. Since the chemicals in chemical barrels are harmful to the human body, long-term contact with people is not good for their health. The existing hoisting process is relatively cumbersome, which increases the time workers spend in close contact with the barrels, which is even more dangerous when there are a large number of them. Utility Model Content
[0003] The purpose of the utility model is to provide a sling that is easy to use, so as to solve the problem of low efficiency when lifting the same kind of objects.
[0004] The technical solutions adopted in this utility model are as follows:
[0005] A convenient-to-use sling comprises a lifting ring, a rotating shaft is provided at the lower part of the lifting ring, the bottom of the rotating shaft is respectively connected to a limiter and two load-bearing rods of the same size, wherein the limiter is fixedly connected directly below the rotating shaft, the two load-bearing rods and the rotating shaft are hinged and symmetrical about the limiter, the lower end of the limiter is connected to a telescopic beam, the two ends of the telescopic beam are respectively hinged to the lower ends of the two load-bearing rods, and two lifting arms are fixed downward on both sides of the telescopic beam.
[0006] Preferably, the rotating shaft can rotate 360°.
[0007] Preferably, the limiter adopts a length-adjustable structure and is provided with a spring.
[0008] Preferably, the telescopic beam consists of a middle tube and telescopic arms at both ends.
[0009] Preferably, the boom is provided with an anti-slip pad and auxiliary wheels.
[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0011] The utility model is provided with a limiter, and the size of the two arms opening when the sling is stationary can be set by adjusting the length of the limiter. When a batch of the same items are lifted, the lifting efficiency and accuracy are accelerated, and the use is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0015] like Figure 1 As shown, a convenient-to-use sling comprises a lifting ring 1, which is used to connect the lifting equipment above. A rotating shaft 2 is provided at the bottom of the lifting ring 1. For easy use, the rotating shaft 2 can rotate 360°. A limiter 3 is welded just below the bottom of the rotating shaft 2. The limiter 3 comprises two unconnected threaded steel bars and a hollow steel pipe with internal threads connecting the two steel bars. The connection between the upper and lower ends of the steel bars and the outside requires at least one spring. Two load-bearing rods 4 of the same size are hinged on both sides of the bottom of the rotating shaft 2. The two load-bearing rods 4 are symmetrical about the limiter 3. The lower end of the limiter 3 is connected to a telescopic beam 5. The telescopic beam 5 consists of an intermediate tube 51 and telescopic arms 52 at both ends. The two ends of the telescopic beam 5 are hinged to the lower ends of the two load-bearing rods 4 respectively, and two lifting arms 6 are fixed downward on both sides of the telescopic beam 5.
[0016] Usage and principle:
[0017] After determining the size of the object to be hoisted (such as the diameter of a medicine barrel), the length of the limiter 3 is changed by rotating the hollow steel tube. At the same time, the distance between the two booms 6 will also change accordingly. Due to the gravity of the boom 6 and the load-bearing rod 4, the telescopic beam 5 will always have a tendency to shrink, so the spring in the limiter 3 will be in a stretched state. When the tension of the spring overcomes this contraction force, the distance between the two booms 6 will be relatively fixed. The operator should adjust the distance between the two booms 6 to be slightly smaller than the distance that the two booms 6 need to be opened during hoisting. In this way, each time the boom is lifted, it is not only convenient for the operator to determine the placement position of the boom 6, but also when placing the boom 6, only the boom 6 needs to be slightly opened to hook the object, which greatly improves the hoisting efficiency and reduces the operator's personal risk when hoisting some dangerous or toxic objects.
[0018] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to modification and variation. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
