Description

Technical Field

[0001] This utility model relates to the field of hoisting, and in particular to a sliding, wear-resistant hoisting rope sleeve. Background Technology

[0002] Existing lifting slings attach a sling to the lifting point of the object being lifted, and the sling is then attached to the crane hook. The crane boom lifts the object. When lifting heavy objects, because the object itself is heavy and has sharp edges or protruding parts, the sharp edges or protruding parts can compress the sling when it is tightened. When the object is heavy, the sling may break due to excessive compression. If the broken wires are inside the sling or in other hard-to-observe areas, continued use poses a significant safety hazard. If the object is heavy enough and has sufficiently sharp edges, it may break the sling directly, causing the object to fall and injure people. In existing technologies, wear-resistant sleeves are usually fixedly installed on the lifting rope sling. When the lifting rope sling is in operation, the wear-resistant sleeve usually comes into contact with the sharp corners of the object being lifted at the same position. The position of the wear-resistant sleeve in contact with the sharp corners is prone to damage, which leads to a short service life of the wear-resistant sleeve. Furthermore, since the wear-resistant sleeve is fixed, the maintenance and repair of the lifting rope sling inside the wear-resistant sleeve becomes inconvenient. Utility Model Content

[0019] (III) Beneficial Effects

[0020] This invention utilizes a sliding anti-abrasion sleeve on the hoisting rope, allowing any position of the sleeve to contact the sharp edges of the object being hoisted. Under frequent use, different positions on the sleeve can cope with wear, thus extending its service life. Furthermore, since the length of the anti-abrasion sleeve on the hoisting rope is less than half the rope's length, maintenance and repair of any part of the rope can be performed simply by sliding the sleeve to expose the corresponding position, facilitating rope maintenance and repair.

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides a sliding anti-abrasion hoisting rope sleeve, which includes a hoisting rope 1 and an anti-abrasion rubber sleeve 2. The anti-abrasion rubber sleeve 2 is fitted onto the hoisting rope 1 and can slide on the hoisting rope 1. The length of the anti-abrasion rubber sleeve 2 on the hoisting rope 1 is less than 1 / 2 of the length of the hoisting rope 1.

[0030] This invention utilizes a sliding anti-abrasion sleeve 2 on the lifting rope 1. During lifting operations, the anti-abrasion sleeve 2 can slide, allowing any position of the sleeve to contact the edges of the object being lifted. Under frequent use, different positions on the sleeve 2 can cope with wear, thus extending its service life. Furthermore, since the length of the anti-abrasion sleeve 2 is less than half the length of the rope 1, maintenance and repair of any position on the rope 1 can be performed simply by sliding the sleeve 2 to expose the corresponding position, facilitating the maintenance and repair of the lifting rope 1.

[0031] Furthermore, the slidable abrasion-resistant hoisting rope sleeve also includes a pair of sliding blocks 3. The sliding blocks 3 are fitted onto the hoisting rope 1 and can slide along the rope 1. Sliding blocks 3 are fixedly installed at both ends of the abrasion-resistant rubber sleeve 2, with the sleeve located between a pair of sliding blocks 3. In this embodiment, the abrasion-resistant rubber sleeve 2 is fixedly connected to the sliding blocks 3, facilitating replacement when the sleeve is damaged.

[0032] Specifically, the sliding block 3 is provided with an annular groove 31, and the end of the anti-wear rubber sleeve 2 is fixedly disposed in the annular groove 31. The sliding block 3 is provided with a fastening hole 32 that penetrates the annular groove 31, and a fastener can pass through the fastening hole 32 and abut against the anti-wear rubber sleeve 2. The fastening hole 32 is provided with an internal thread, and the fastener is a bolt. When replacing the anti-wear rubber sleeve 2, it is only necessary to make the anti-wear rubber sleeve 2 not closed, use the anti-wear rubber sleeve 2 to wrap the suspension rope 1, and then insert the two ends of the anti-wear rubber sleeve 2 into the corresponding annular groove 31 on the sliding block 3, and finally use the fastener to fix the anti-wear rubber sleeve 2 and the sliding block 3 in place. In the above solution, the anti-wear rubber sleeve 2 is made easy to replace.

[0033] In one embodiment, the sliding block 3 includes two arc-shaped half-blocks 33, which are joined together to form a sliding hole. The two arc-shaped half-blocks 33 are sleeved on the suspension rope 1 through the sliding hole. An annular groove 31 is provided at the end of the arc-shaped half-block 33, and fastening holes 32 are provided on the sidewalls of the arc-shaped half-block 33.

[0034] In another embodiment, sealing blocks 11 are provided near both ends of the lifting rope 1, and the ends of the lifting rope 1 are fixed inside the corresponding sealing blocks 11. The outer surface of the first end of the sealing block 11 is a slope, and the first end of the sealing block 11 is the end of the sealing block 11 facing away from the lifting rope 1. The sealing blocks 11 completely seal the ends of each lifting rope 1 inside, preventing the wire rope ends from piercing the workers; the ends of the sealing blocks 11 are sloped to prevent them from being stuck due to steps or sharp edges during lifting, improving passability and overall aesthetics.

[0035] Finally, the length of the anti-abrasion rubber sleeve 2 is 1.2m-1.8m. In actual use, the height of the object being hoisted is generally within three meters. During hoisting, the user only needs to lift the anti-abrasion rubber sleeve 2 by hand to exceed three meters, and can then adjust the contact point between the anti-abrasion rubber sleeve 2 and the object being hoisted as needed. In addition, two anti-abrasion rubber sleeves 2 are provided on the hoisting rope 1, which can handle multiple sharp edges. The anti-abrasion rubber sleeve 2 has a steel wire wear-resistant layer inside, further improving its service life.

[0036] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
