Description

Technical Field

[0001] The present application relates to the field of traction ropes, and in particular to a traction rope with a flexible sleeve. Background Art

[0002] The existing traction ropes usually include a traction rope body and a sleeve sleeved on the outside of the traction rope body. The current sleeves include spring sleeves and PVC sleeves, which have good wear resistance, protection and strength.

[0003] As disclosed in CN204300092U, the clutch cable comprises a cable assembly, on which a first cable joint assembly, a first sleeve cap assembly, a second sleeve cap assembly, a dust cover assembly and a second cable joint assembly are sequentially arranged, the cable assembly comprises a steel wire rope core, an inner lining tube layer arranged on the outer layer of the steel wire rope core, a steel belt sleeve layer arranged on the outer layer of the inner lining tube layer, and a PVC sleeve wrapping layer arranged on the steel belt sleeve layer; the first cable joint assembly is fixedly connected to the steel wire rope core at one end of the cable assembly, and the second cable joint assembly is fixedly connected to the other end of the cable assembly; by arranging the cable assembly into a four-layer structure of a steel wire rope core, an inner lining tube layer, a steel belt sleeve layer and a PVC sleeve wrapping layer, the overall strength of the cable assembly is improved, thereby improving the safety factor of the clutch.

[0004] However, the above scheme also has certain disadvantages. Since the traction rope needs to be laid out according to the design plan of the frame during installation and use, it needs to be bent. The current practice is to fix it on the frame through a clip, and the traction rope is positioned by the clip. Since both the spring sleeve and the PVC sleeve are currently used, due to their hard material, it is difficult to bend during layout and inconvenient to install. After the layout, the friction between the traction rope and the inner wall of the tube is large, the traction rope is severely worn, and even breaks.

[0005] In view of this, those skilled in the art need to improve the existing traction rope to overcome the above-mentioned defects. Utility Model Content

[0006] The main purpose of the present application is to provide a traction rope with a flexible sleeve. The traction rope has good overall flexibility. When performing layout planning, the good flexibility facilitates installation and layout. In addition, the friction between the traction rope and the sleeve will not increase due to bending.

[0007] In order to achieve the above-mentioned objectives, in a first aspect, the present application provides a traction rope with a flexible sleeve, comprising a flexible sleeve assembly, a traction rope body inserted into the flexible sleeve assembly, the flexible sleeve assembly comprising a flexible tube body, sleeve ends fixedly arranged at both ends of the flexible tube body, and a plurality of spherical supports arranged in the flexible tube body, each of the spherical supports being provided with a through hole for the traction rope body to pass through, the flexible tube body being made of polyethylene material, and the diameter of the spherical support being 90%-99% of the diameter of the flexible tube body.

[0008] A further improvement is that the spherical support member is one of an iron ball, a steel ball, a plastic ball, and a wooden ball.

[0009] A further improvement is that trumpet-shaped expansion grooves are provided at both ends of the perforation on the spherical support member.

[0010] A further improvement is that the sleeve end is fixed to the flexible pipe body by buckling.

[0011] A further improvement is that both ends of the flexible pipe body have concave-convex sections, wavy sections or serrated sections.

[0012] A further improvement is that the traction rope body includes a traction rope and connectors fixedly arranged at both ends of the traction rope.

[0013] A further improvement is that the connector is fixed to the traction rope by welding or pressing.

[0014] A further improvement is that the traction rope is formed by twisting a plurality of round wires.

[0015] The utility model provides a traction rope with a flexible sleeve. Compared with the prior art, its beneficial effect is that a polyethylene sleeve is used to replace the original PVC tube or spring sleeve. Therefore, during layout planning, it is easier to install due to its good flexibility. In addition, by arranging a plurality of spherical support members in the flexible tube body, it is not only used to provide good support for the flexible tube body, but also, during layout bending, a plurality of spherical support members are gathered at the bending position, which improves the support effect and strength while avoiding an increase in friction between the traction rope body and the inner wall of the flexible sleeve, thereby reducing the wear of the traction rope body.

[0025] In addition, the term "plurality" shall mean two or more.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1-Figure 3 As shown, a traction rope with a flexible sleeve comprises a flexible sleeve assembly, a traction rope body 6 inserted into the flexible sleeve assembly, the flexible sleeve assembly comprises a flexible tube body 1, sleeve ends 5 fixedly arranged at both ends of the flexible tube body 1, and a plurality of spherical support members 2 arranged in the flexible tube body 1, each of the spherical support members 2 is provided with a through hole 3 for the traction rope body 6 to pass through, the flexible tube body 1 is made of polyethylene material, the diameter of the spherical support member 2 is 90%-99% of the diameter of the flexible tube body 1, preferably, the diameter of the spherical support member 2 is 95% of the diameter of the flexible tube body 1, the spherical support member 2 can be displaced in the flexible tube body 1, but the gap between the two cannot be too large, and since the flexible tube body 1 is not a full round tube, the spherical support member 2 can prop it up.

[0028] The key means of the present application include using a softer polyethylene material to replace the original PVC material sleeve, which has better flexibility and is therefore more convenient to bend during layout planning. In addition, by providing a plurality of spherical support members 2, it not only serves the purpose of supporting the sleeve, but also the traction rope directly passes through the perforation 3 on the spherical support member 2 to avoid contact with the inner wall of the sleeve, and when bending, part of the spherical support member 2 is gathered at the bend, which not only improves the strength, but also avoids an increase in friction between the traction rope and the inner wall of the sleeve at the bend, thereby avoiding excessive wear of the traction rope.

[0029] The spherical support member 2 is one of an iron ball, a steel ball, a plastic ball, and a wooden ball. A plastic ball is preferably used because the friction between metal and plastic is small and the overall weight can be reduced, thereby reducing production costs.

[0030] In order to reduce the friction between the traction rope and the end of the through hole 3 on the spherical support member 2 , trumpet-shaped expansion grooves 4 are provided at both ends of the through hole 3 on the spherical support member 2 .

[0031] For the convenience of processing, the sleeve end 5 is fixed to the flexible tube body 1 by buckling. After the flexible tube body 1 is formed, the traction rope is passed through the spherical support 2, and the spherical support 2 is placed one by one in the flexible tube body 1. Finally, the sleeve end 5 is buckled at both ends to prevent the spherical support 2 from detaching from the flexible tube body 1.

[0032] In order to make the connection between the sleeve end 5 and the flexible pipe body 1 tighter, the two ends of the flexible pipe body 1 have concave and convex sections, wavy sections or serrated sections. Since the sleeve end 5 is usually a metal part, the above structure can increase the contact surface between the sleeve end 5 and the flexible pipe body 1, thereby improving the friction between the two after buckling, making the two tight.

[0033] Preferably, the traction rope body 6 includes a traction rope and connectors fixedly arranged at both ends of the traction rope, the connectors are welded or fixed to the traction rope, and the traction rope is formed by twisting a plurality of round wires.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
