Description

Technical Field

[0001] The utility model relates to the technical field of lifting belts, in particular to a corrosion-resistant and anti-aging lifting belt. Background Technique

[0002] As an important industrial product, the lifting belt plays a crucial role in modern lifting operations. Its material is generally made of high-strength polyester filaments. High strength is one of the most prominent characteristics of the lifting belt, enabling the lifting belt to bear huge weights and meet various lifting requirements, making the lifting belt perform excellently in the lifting operations of heavy equipment and large components.

[0003] When the existing lifting belt is used in a corrosive environment, it will be eroded by various chemical substances. Moreover, in the environments of exposure to the sun, humidity and high temperature, the strength and durability of the lifting belt will decrease, which will accelerate the aging of the lifting belt and shorten its service life. At the same time, when the sling is bent, the hook hung on the sling ear is likely to become detached from the sling ear, which will not only affect the progress of the lifting operation but also may cause safety accidents. Therefore, we provide a corrosion-resistant and anti-aging lifting belt. Content of the Utility Model

[0004] The utility model provides a corrosion-resistant and anti-aging lifting belt to solve the technical problems existing in the above background technique.

[0005] The purpose and effect of a corrosion-resistant and anti-aging lifting belt of the utility model are achieved by the following specific technical means: A corrosion-resistant and anti-aging lifting belt includes two sling ears. The ends of the two sling ears close to each other are fixedly connected with a sling body together. A clamping assembly is arranged on the outer surface of each sling ear. Each clamping assembly includes a pressing plate arranged on the front of the sling ear. Two chutes are opened on the front of each pressing plate. A sliding plate is slidably connected to the inner wall of each chute. The rear ends of the two sliding plates are fixedly connected with a clamping plate together.

[0006] The sling body is composed of a polypropylene fiber layer, a polyester fiber layer, a polyethylene layer and a polyamide fiber layer. Polyester fiber layers are fixedly connected to the left and right sides of the polypropylene fiber layer.

[0007] Polyethylene layers are fixedly connected to the sides of the two polyester fiber layers away from each other. Polyamide fiber layers are fixedly connected to the sides of the two polyethylene layers away from each other.

[0008] The clamping assembly further includes a connecting plate, and the back of the connecting plate is connected to the front ends of the two sliding plates.

[0009] The front surface of the connecting plate is provided with threaded holes, and the inner wall of the threaded holes is threadedly connected with threaded posts. The rear end of the threaded posts is rotatably connected to the front surface of the pressing plate.

[0010] Each sling ear has an anti-wear layer fixedly connected to its outer surface, and two baffles are fixedly connected to the outer surface of each sling ear.

[0011] Beneficial effects:

[0012] Through the cooperation of the polypropylene fiber layer and the polyester fiber layer provided, the effects of enhancing anti-corrosion, light resistance and sun resistance can be achieved, thereby extending the service life of the sling body. Through the cooperation of the polyethylene layer and the polyamide fiber layer, the high-temperature resistance effect of the sling body can be enhanced, and at the same time, the wear resistance of the sling body can be ensured.

[0013] Through the cooperation of the pressing plate, the clamping plate, the chute, the sliding plate, the connecting plate, the threaded hole and the threaded post provided, by rotating the threaded post, the threaded post can be made to push the pressing plate towards the sling ear, and the pressing plate and the clamping plate will gradually clamp the sling ear, so that the hook hung on the sling ear can be tightly connected to the sling ear, preventing the hook from detaching from the sling ear, ensuring the normal progress of the hoisting operation and avoiding safety accidents.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown in the attached Figure 1 to the attached Figure 4 figures: A corrosion-resistant and anti-aging lifting belt includes two sling ears 1. The ends of the two sling ears 1 close to each other are fixedly connected together with a sling body 2. The sling body 2 is composed of a polypropylene fiber layer 201, a polyester fiber layer 202, a polyethylene layer 203, and a polyamide fiber layer 204. Polyester fiber layers 202 are fixedly connected to both the left and right sides of the polypropylene fiber layer 201, which can ensure the anti-corrosion, light resistance, and sun resistance effects of the sling body 2, thereby extending the service life of the sling body 2.

[0022] Polyethylene layers 203 are fixedly connected to the sides of the two polyester fiber layers 202 away from each other, and polyamide fiber layers 204 are fixedly connected to the sides of the two polyethylene layers 203 away from each other, which can enhance the high-temperature resistance effect of the sling body 2 and at the same time ensure the abrasion resistance of the sling body 2, and can extend the service time of the sling body 2.

[0023] A clamping assembly 3 is provided on the outer surface of each sling ear 1. Each clamping assembly 3 includes a pressing plate 301 arranged on the front of the sling ear 1. Two sliding grooves 302 are opened on the front of each pressing plate 301. A sliding plate 303 is slidably connected to the inner wall of each sliding groove 302. A clamping plate 304 is fixedly connected to the rear ends of the two sliding plates 303. The clamping assembly 3 further includes a connecting plate 305. The back surface of the connecting plate 305 is connected to the front ends of the two sliding plates 303. A threaded hole 306 is opened on the front surface of the connecting plate 305. A threaded column 307 is threadedly connected to the inner wall of the threaded hole 306. The rear end of the threaded column 307 is rotatably connected to the front surface of the pressing plate 301. A turning handle is fixedly connected to the front end of the threaded column 307. The threaded column 307 can be conveniently rotated by using the turning handle. At the same time, the threaded column 307 will gradually move and push the pressing plate 301. The pressing plate 301 will gradually approach the sling ear 1. The clamping plate 304 and the pressing plate 301 will form a clamping state on the sling ear 1, so that the hook and the sling ear 1 can be stably connected, and the separation between the hook and the sling ear 1 can be avoided.

[0024] An anti-wear layer 4 is fixedly connected to the outer surface of each sling ear 1, and two baffles 5 are fixedly connected to the outer surface of each sling ear 1. The anti-wear layer 4 is made of polyester material, which can avoid friction between the hook and the sling ear 1, ensuring the service life of the sling ear 1. At the same time, the position of the hook can be restricted by the baffle 5, ensuring that the hook is on the anti-wear layer 4.

[0025] Working principle: When in use, hang the hook on the sling ear 1, then sleeved the splint 304 and the pressing plate 301 outside the sling ear 1, and then rotate the threaded column 307. The threaded column 307 will rotate and gradually move inside the threaded hole 306. At the same time, the threaded column 307 will push the pressing plate 301 towards the sling ear 1. The pressing plate 301 and the splint 304 will clamp the sling ear 1, effectively preventing the hook from detaching from the sling ear 1, ensuring the normal progress of the hoisting operation and avoiding safety accidents.
