Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to an anti-falling sling. Background Art

[0002] As lifting tools, slings are widely used in manufacturing, processing, maintenance and logistics industries.

[0003] The slings in the prior art all include a lifting bracket with a hook on the bracket. The sling is fixed to the lifting wire rope of the lifting equipment through the bracket. The lifting equipment pulls the hanger through the lifting ring on the hanger, and the hanger lifts the object through the hook, thereby realizing the lifting and transportation of the object. However, since the structure of the hook is relatively simple, it is not conducive to the stability of the object during the lifting process when lifting the object, and the lifted object is prone to fall off. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide an anti-falling hanger to solve the problems raised by the above background technology.

[0005] Based on the above purpose, the utility model provides an anti-falling sling, including a sling body, a sling ring is fixedly arranged on the top of the sling body, an upper sling arm is fixedly arranged vertically downward on one end of the sling body, a lower sling arm is adjustable up and down at the bottom of the upper sling arm, a locking piece is arranged on one side of the upper sling arm for fixing the lower sling arm after adjusting its length, a slinging part is extended vertically at the bottom of the lower sling arm, a mounting groove is arranged on the side of the sling part close to the sling body, and an anti-falling component is arranged inside the mounting groove;

[0006] After the lifting object is placed on the lifting part, the lifting object is clamped by the anti-slip assembly to improve the stability of the lifting object.

[0007] Preferably, an adjustment slot is extended upwardly from the bottom of the upper suspension arm, and the lower suspension arm is inserted into the adjustment slot.

[0008] Preferably, the locking member includes a positioning pin, one end of which passes through the upper suspension arm and is arranged inside the adjustment slot, and the lower suspension arm is provided with a plurality of evenly distributed limiting holes, and the positioning pin is inserted into the corresponding limiting holes to fix the upper suspension arm and the lower suspension arm.

[0009] Preferably, an anti-slip groove is provided on the outer wall of the positioning pin, and the anti-slip groove cooperates with the limiting hole to ensure that the positioning pin will not slip out of the limiting hole during use.

[0010] Preferably, the anti-fall-off component comprises:

[0011] The anti - detachment rod is arranged inside the installation groove. One part of the anti - detachment rod close to the lower lifting arm is hinged to the inside of the installation groove through a rotating shaft, and an anti - detachment head is provided upward at one end of the anti - detachment rod far from the lower lifting arm.

[0012] The pushing block has one side fittingly arranged on one side of the installation groove close to the lower lifting arm, and the other side is arranged on the top of the anti - detachment rod.

[0013] The elastic support member has one end fixedly connected to the bottom of the installation groove and the other end fixedly connected to the bottom of the pushing block.

[0014] Wherein, by pressing down the pushing block, the pushing block drives one end of the anti - detachment rod to turn downward, and the anti - detachment head turns upward to clamp the lifted object.

[0015] Preferably, anti - slip grooves are processed on both the upper end surface of the anti - detachment rod and the anti - detachment head.

[0016] The beneficial effects of the present utility model: By setting the distance between the upper lifting arm and the lower lifting arm to be adjustable, it can be applied to objects of different sizes. At the same time, anti - detachment grooves are opened on the positioning pins to prevent the positioning pins from falling off, realizing stable lifting; and inside the lower lifting arm, the pushing block and the anti - detachment rod adopt a linkage structure. When lifting an object, due to its own gravity, by pressing down the pushing block, the anti - detachment rod and the anti - detachment head can tightly press the lifted object, effectively avoiding the falling off of the lifted object.

[0033] As an alternative embodiment, the anti - detachment assembly includes:

[0034] An anti - detachment rod 10 is arranged inside the installation groove 9. One end of the anti - detachment rod 10 close to the lower suspension arm 4 is hinged to the inside of the installation groove 9 through a rotating shaft 11, and an anti - detachment head 12 is provided upward at the end of the anti - detachment rod 10 far from the lower suspension arm 4;

[0035] A push block 8, one side of which is attached to the side of the installation groove 9 close to the lower suspension arm 4, and the other side is arranged on the top of the anti - detachment rod 10;

[0036] An elastic support member 15, one end of which is fixedly connected to the bottom of the installation groove 9, and the other end is fixedly connected to the bottom of the push block 8;

[0039] The working principle of the present utility model is as follows: When it is necessary to hoist an object, first, according to the size of the object, move the lower lifting arm 4 in the adjustment groove 7 of the upper lifting arm 3 so that the limit hole 5 on the lower lifting arm 4 corresponds to the corresponding positioning hole on the upper lifting arm 3. Then, insert the positioning pin 6. And under the self-weight of the lower lifting arm 4, the lower part of the limit hole 5 on the lower lifting arm 4 is clamped into the anti-drop groove 13 on the positioning pin 6 to prevent the positioning pin 6 from falling off. At this time, the hoisting size of the hoisting tool body 1 is adjusted. Then, the object to be hoisted, especially an object in the shape of a ring, is sleeved into the lower lifting arm 4. Then, the hoisting equipment hoists through the lifting ring 2. During the rising process of the hoisting tool body 1, the hoisted object presses down the pushing block 8 on the inner side of the lower lifting arm 4. The pushing block 8 moves downward inside the installation groove 9, and the pushing block 8 presses the elastic support member 15 below it. The elastic support member 15 can be a spring, a spring piece or other elastic materials with a support structure. One end of the anti-drop rod 10 is pressed down by the pushing block 8 during the downward movement. The anti-drop rod 10 rotates clockwise through the rotating shaft 11. At this time, the other end of the anti-drop rod 10 moves out of the installation groove 9, and the anti-drop head 12 at the outer end of the anti-drop rod 10 contacts the side of the hoisted object, achieving the clamping effect on the hoisted object. Anti-slip grooves 14 are processed on the upper end surface of the anti-drop rod 10 and the anti-drop head 12 to further prevent the hoisted object from falling off.
