Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction rope technology, and in particular to a double-layer colored sheath traction rope with a force-bearing rope lock. Background Technology
[0002] A traction rope is a type of rope used in various applications, including hoisting operations, agriculture, construction, rescue, shipbuilding, and automotive. The material and specifications of traction ropes vary depending on the specific application and requirements. Common traction rope materials include steel wire rope, nylon rope, leather rope, and metal rope. Power traction ropes are used in the power, telecommunications, railway, and communications sectors for laying conductors, cables, and fiber optic cables. They are also used for overhead power line laying and traction in various complex terrain conditions. These products are characterized by high tensile strength, ease of use, and suitability for various field construction projects, including traction of fiber optic cables and other operations. The traction rope has an outer insulation layer that isolates the power source, protecting the operator's safety during operations. However, if the external layer is damaged, it will not function effectively. Existing power line laying traction ropes, under prolonged external pressure, are prone to creep in the internal core, leading to difficulty in unwinding or knotting during unwinding.
[0003] Therefore, it is necessary to provide a new type of double-layer colored sheathed traction rope with a force-bearing rope lock to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a double-layer colored sheath traction rope for force-bearing rope locks.
[0005] The double-layer colored sheath traction rope of the force rope lock provided by this utility model includes a triangular inner liner frame, on which multiple annularly distributed traction rope cores are embedded, and an inner sheath is fixedly sleeved on the triangular inner liner frame.
[0006] The inner sheath is fitted with multiple ring-shaped curved steel wires:
[0007] An outer sheath is fixedly fitted onto the inner sheath, and several ring-shaped rubber balls are fixedly embedded on the outer sheath.
[0008] Preferably, the curved steel wire is inserted into the curved groove of the inner sheath, and the end of the curved steel wire extends out of the curved groove of the inner sheath. Both sides of the extended end of the curved steel wire are provided with protrusions.
[0009] Preferably, each corner of the triangular inner liner is fixedly fitted with an arc-shaped rubber strip, and the arc-shaped rubber strip is fixedly connected to the inner wall of the inner sheath.
[0010] Preferably, the inner core of the traction rope is made of ultra-high molecular weight polyethylene fiber, and the diameter of the inner core of the traction rope is 30mm.
[0011] Preferably, the inner and outer sheaths are coated with paints of different colors, and the inner sheath is also coated with fluorescent liquid.
[0012] Preferably, the outer sheath is coated with an RTV anti-flashover coating.
[0013] Compared with related technologies, the double-layer colored sheath traction rope of the force-bearing rope lock provided by this utility model has the following beneficial effects:
[0014] This utility model features an inner and outer sheath in its traction rope, which greatly improves the rope's strength. The curved steel wire strip on the inner sheath has an elastic structure, which enhances the rope's resistance to creep. The rubber ball on the outer sheath improves the rope's compressive strength and makes it easier for workers to pull the rope, effectively protecting their hands when pulling it.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] Please see Figures 1 to 2 The present invention provides a double-layer colored sheathed traction rope for a force-bearing rope lock, which includes: a triangular inner liner 1, a traction rope inner core 2, an inner sheath 3, and an outer sheath 4.
[0021] In the embodiments of this utility model, please refer to Figure 1 and Figure 2The triangular inner liner 1 has multiple annularly distributed traction rope cores 2 embedded in it. The traction rope cores 2 are made of ultra-high molecular weight polyethylene fiber and have a diameter of 30mm, which gives the traction rope the characteristics of high tensile strength and light weight. The triangular inner liner 1 is fixedly fitted with an inner sheath 3. The inner sheath 3 has multiple annularly distributed curved steel wires 5 embedded in it. The curved steel wires 5 are inserted into the curved grooves opened in the inner sheath 3, and the ends of the curved steel wires 5 extend out of the curved grooves opened in the inner sheath 3. Both sides of the extended ends of the curved steel wires 5 are provided with protrusions 51. The inner sheath 3 is fixedly fitted with an outer sheath 4, and the outer sheath 4 is fixedly fitted with several annularly distributed rubber balls 6.
[0022] It should be noted that the inner sheath 3 and outer sheath 4 are set in the traction rope, which greatly improves the strength of the traction rope. At the same time, the curved steel wire strip 5 set on the inner sheath 3 is an elastic structure, which can improve the creep resistance of the traction rope. The rubber ball 6 set on the outer sheath 4 improves the compressive strength of the traction rope and makes it easier for the staff to pull the traction rope, effectively improving the protection of the hands when pulling the traction rope.
[0023] Among them, each corner of the triangular inner liner 1 is fixedly fitted with an arc-shaped rubber strip 11, and the arc-shaped rubber strip 11 is fixedly connected to the inner sleeve wall of the inner sheath 3, thereby improving the compressive strength of the traction rope.
[0024] The inner sheath 3 and the outer sheath 4 are coated with different colors of paint, so that when the outer sheath 4 is damaged, the inner sheath 3 can be immediately displayed, allowing the user to quickly know the location of the damage. In addition, the inner sheath 3 is also coated with fluorescent liquid, which makes it convenient to display the location of the damage to the outer sheath 4 at night.
[0025] The outer sheath 4 is coated with RTV anti-flashover paint, which prevents sewage from entering the traction rope from the outer sheath 4 and damaging the internal rope.
[0026] The working principle of the double-layer colored sheath traction rope of the force-bearing rope lock provided by this utility model is as follows:
[0027] The traction rope is equipped with an inner sheath 3 and an outer sheath 4, which greatly improves the strength of the traction rope. At the same time, the curved steel wire strip 5 on the inner sheath 3 is an elastic structure, which can improve the creep resistance of the traction rope. The rubber ball 6 on the outer sheath 4 improves the compressive strength of the traction rope and makes it easier for workers to pull the traction rope, effectively improving the protection of the hands when pulling the traction rope.
