Casting-free pear-shaped rope sleeve

Abstract

The utility model provides a casting-free pear-shaped rope sleeve which solves the problem that an existing steel rope tool cannot well clamp a steel wire rope. The rope core is characterized by further comprising a crumple groove which is arranged in the vertical direction of the spiral column, and the width of the crumple groove is smaller than the diameter of the rope core connecting hole. And the anti-skid lines are arranged on the inner wall of the rope core connecting hole. When the rope core of the steel wire rope displaces, the rope core connecting hole shrinks to tightly clamp the rope core by reducing the clearance of the crumple groove, and meanwhile, the friction force between the rope core connecting hole and the rope core is greatly increased by the anti-slip lines of the rope core connecting hole, so that the clamping is firmer, the steel wire rope is prevented from being damaged, and the purpose of reducing the cost is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope slings, in particular to a casting-free pear-shaped rope loop. Background Art

[0002] Rigging is one of the important auxiliary tools to ensure the safety of operations, and the safety of rigging has always been one of the topics that people study. It ranges from small rigging for climbing to large rigging for ships and other equipment, especially the rigging needed for unloading ships. The quality of the rigging needs to be up to standard, otherwise it is easy to cause safety accidents. Most of the existing wire rigging are fixed by casting and other methods.

[0003] However, most of the steel rigging now has the following problems:

[0004] 1. Poor safety. Currently, most steel rigging is fixed by casting. After the steel wire rigging is used for a period of time, it is difficult to find the broken wire inside the steel wire because it is cast, which increases the danger of the entire device.

[0005] Second, it is time-consuming and labor-intensive. At present, most of the steel rigging needs to be heated to melt the alloy during casting. The melting point of the alloy is very high, and when the alloy melts, it has high requirements for various factors such as the environment, which makes the molding speed of the entire device slow.

[0006] After searching, the patent: A new type of cast-free pear-shaped sleeve with self-locking spiral core steel rigging (CN201922425078.9), including a pear-shaped sleeve body, a first strand of steel wire rope, a tapered pin, a second strand of steel wire rope and a third strand of steel wire rope, the inside of the pear-shaped sleeve body is provided with a receiving groove, and the surface of the receiving groove is provided with a first strand of steel wire rope, the first strand of steel wire rope is twisted and connected with the second strand of steel wire rope, and the first strand of steel wire rope is twisted and connected with the third strand of steel wire rope, the surface of the central steel wire rope is connected with a tapered pin, and the surface of the tapered pin is provided with a through hole, and the surface of the tapered pin is welded with a fixing groove, and the surface of the first strand of steel wire rope is connected with a locking steel wire. Although the above patent can solve the problems existing in steel rigging and improve efficiency, the rope core has a relative displacement relative to the rope strand when the steel wire rope is bent through the pulley. In some cases, the rope core displacement is too large, and the rope core is squeezed in the middle section of the steel wire rope. After continued use, the steel wire rope core leaks out, and the steel wire rope is eventually scrapped and cannot be used, which increases the cost.

[0007] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a new type of cast-free pear-shaped rope loop with a view to making it more valuable for industrial use. Utility Model Content

[0008] In order to overcome the shortcomings of the background technology, the utility model provides a casting-free pear-shaped rope loop, which solves the problem that the existing steel rigging cannot clamp the steel wire rope well.

[0009] The technical solution adopted by the utility model is as follows:

[0010] A casting-free pear-shaped rope sleeve, comprising a pear-shaped sleeve body, a spiral column and a steel wire rope, wherein a receiving hole is provided inside the pear-shaped sleeve body, the receiving hole is in a conical structure, the steel wire rope is clamped in the receiving hole through the spiral column, a rope core connecting hole for connecting the steel wire rope core is provided on the central axis of the spiral column, and an installation groove for assembling the steel wire rope strand is provided on the spiral column, and further comprising:

[0011] A collapse groove is arranged along the vertical direction of the spiral column, and the width of the collapse groove is smaller than the diameter of the rope core connection hole;

[0012] Anti-slip patterns are arranged on the inner wall of the rope core connection hole.

[0013] The width of the collapse groove is 2 to 5 mm.

[0014] The anti-slip pattern is a spiral pattern.

[0015] The depth of the spiral pattern is between 0.5 and 1.0 mm.

[0016] The installation groove is in a spiral structure and is arranged on the spiral column.

[0017] The installation grooves are provided with 6 or 8 grooves.

[0018] The spiral column has a conical structure and is arranged to match the receiving hole.

[0019] The beneficial effects of the utility model are:

[0020] The utility model can ensure that when the core of the steel wire rope is displaced, the gap of the collapse groove becomes smaller, so that the core connection hole contracts and tightly clamps the core. At the same time, the anti-skid pattern of the core connection hole greatly increases the friction between the core connection hole and the core, and the clamping is tighter, ensuring that the steel wire rope is not damaged, thereby achieving the purpose of reducing costs.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0027] In the embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a casting-free pear-shaped rope sleeve comprises a pear-shaped sleeve body 1, a spiral column 2 and a steel wire rope 3. The pear-shaped sleeve body 1 is provided with a receiving hole 4, and the receiving hole 4 is a conical structure. The steel wire rope 3 is clamped in the receiving hole 4 through the spiral column 2. The central axis of the spiral column 2 is provided with a rope core connecting hole 21 for connecting the steel wire rope core. The spiral column 2 is provided with an installation groove 22 for assembling the steel wire rope strands, and further comprises:

[0028] The collapse groove 23 is arranged along the vertical direction of the spiral column 2, and the width of the collapse groove 23 is smaller than the diameter of the rope core connection hole 21;

[0029] The anti-slip pattern 24 is arranged on the inner wall of the rope core connecting hole 21 .

[0030] The width of the collapse groove 23 is 2-5 mm.

[0031] The anti-slip pattern 24 is a spiral pattern.

[0032] The depth of the spiral pattern is between 0.5 and 1.0 mm.

[0033] The mounting groove 22 is formed in a spiral structure and is disposed on the spiral column 2 .

[0034] The installation grooves 22 are provided with 6 or 8 grooves.

[0035] The spiral column 2 is of a conical structure and is matched with the receiving hole 4 .

[0036] Based on the above embodiments, the width of the collapse groove 23 in the present invention is 4 mm, the depth of the spiral pattern 24 is 1.0 mm, and the installation groove 22 is formed on the spiral column 2 in a spiral structure, and 6 installation grooves 22 are formed.

[0037] During the specific installation, the strands of the wire rope 3 are spread out and inserted into the installation grooves 22 of the spiral column 2 respectively, and the wire rope core is inserted into the rope core connecting hole 21 in the center of the spiral column 2. Then the end of the wire rope is pulled, and the wire rope inserted into the rope strand drives the spiral column 2 to move downward. At this time, the conical structure of the accommodating hole 4 and the spiral column 2 squeeze each other, so that the wire rope strands are firmly stuck; but because the rope core connecting hole 21 of the spiral column 2 is larger than the rope core diameter and there is a gap, the rope core has a relative displacement relative to the rope strand when the wire rope passes through the pulley and the rope core displacement is also too large. At this time, when the spiral column 2 is squeezed, the gap of the collapse groove 23 becomes smaller, so that the rope core connecting hole 21 contracts to tightly clamp the rope core. At the same time, the spiral texture of the rope core connecting hole 21 greatly increases the friction between the hole and the rope core, and the clamping is tighter.

[0038] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
