Description

Technical Field

[0001] The utility model relates to the technical field of flame-retardant ropes, in particular to a low-smoke and fire-insulating flame-retardant rope. Background Art

[0002] Flame retardant rope is a product widely used in electronics, semiconductors, optoelectronics, optical fiber manufacturing and other industries. Flame retardant rope can effectively eliminate static electricity caused by friction on the machine and avoid the adverse effects caused by static electricity during the printing process. The flame retardant rope is made of electrostatic sub-conductor material, which can instantly conduct static electricity to the ground without charge. Once static electricity discharge occurs, it can effectively limit the discharge pulse current to below 5mA, and the discharge spark is very small, which is not enough to ignite the explosive gas mixed with combustible gas and air, so as to achieve the purpose of conductive explosion prevention. In order to improve the efficiency of conductive explosion prevention of machines, a flame retardant rope is needed, but the existing flame retardant rope still has the following shortcomings:

[0003] For example, the utility model with application number 202123030483.4 discloses a high-temperature flame-retardant rope, which can enable the flame-retardant rope body to achieve better protection effect during use, so as to improve the safety of the flame-retardant rope body during use. However, similar to the comparative documents of the above-mentioned application, when the existing flame-retardant ropes are used, most flame-retardant ropes are prone to emit harmful smoke if they encounter open flames during use, which makes the use environment and the physical and mental health of the staff easily affected, resulting in reduced practicality and reduced use efficiency of the flame-retardant rope.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a low-smoke and fire-proof flame-retardant rope is proposed. Utility Model Content

[0005] The utility model aims to provide a low-smoke and fire-proof flame-retardant rope to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-smoke and fire-proof flame-retardant rope, comprising a flame-retardant rope main body and a polyetheretherketone layer, a fire-retardant coating layer is arranged on the outside of the flame-retardant rope main body, a polyetheretherketone layer is arranged on the inside of the fire-retardant coating layer, and a flame-retardant fiber layer is arranged inside the polyetheretherketone layer, and a polyethylene fiber layer is additionally arranged inside the flame-retardant fiber layer, a rope core main body is arranged inside the polyethylene fiber layer, and a limiting component is arranged outside the flame-retardant rope main body.

[0007] Furthermore, the inner dimensions of the fire retardant coating layer match the outer dimensions of the polyetheretherketone layer, and the inner side of the fire retardant coating layer fits tightly with the outer side of the polyetheretherketone layer.

[0008] Furthermore, a polyethylene fiber layer and a polyetheretherketone layer are respectively arranged on the inner and outer sides of the flame-retardant fiber layer, and the flame-retardant fiber layer is arranged and confined between the polyethylene fiber layer and the polyetheretherketone layer.

[0009] Furthermore, the limiting assembly includes a workbench, a supporting vertical rod, a servo motor and a wire-taking roller. Support vertical rods are installed on both sides of the upper end of the workbench, and a servo motor is arranged outside the supporting vertical rod, and the front end of the servo motor is connected to the wire-taking roller.

[0010] Furthermore, the limit assembly also includes a mounting seat, a spring damping rod and a limit plate. A mounting seat is arranged in the middle of the upper end of the workbench, a spring damping rod is arranged at the upper end of the mounting seat, and a limit plate is installed at the upper end of the spring damping rod.

[0011] Furthermore, the outer side of the wire take-up roller is flush with the outer side of the workbench, and the wire take-up roller is rotatably connected to the workbench via a servo motor.

[0012] Furthermore, the spring damping rod is vertically distributed to the workbench, and the spring damping rod is threadedly connected to the workbench through a mounting seat.

[0013] Furthermore, the outer side of the limit plate is flush with the outer side of the workbench, and the limit plate is elastically connected to the workbench via a spring damping rod.

[0014] The utility model provides a low-smoke and fire-proof flame-retardant rope, which has the following beneficial effects:

[0015] 1. The utility model can use the polyetheretherketone layer to prevent most flame-retardant ropes from emitting harmful smoke when encountering open flames during use, which may affect the use environment and the physical and mental health of workers and reduce the practicality of the flame-retardant rope. The fire-retardant coating layer arranged on the outermost side of the flame-retardant rope body increases the overall fire resistance of the flame-retardant rope. At the same time, the polyetheretherketone layer arranged on the inner side of the fire-retardant coating layer has good flame retardancy and is difficult to burn under normal conditions. Even if it burns, The amount of smoke and harmful gas released is also very low, thereby improving the safety of the flame retardant rope during use. The flame retardant fiber layer arranged inside the polyetheretherketone layer further improves the overall fire barrier of the flame retardant rope. The polyethylene fiber layer arranged inside the flame retardant fiber layer has polymerization properties and can expand rapidly at high temperatures to form an insulating layer, thereby preventing the spread of flames. Polyethylene fiber is one of the most widely used high-temperature flame retardant rope materials in the current industrial field. The rope core body is protected by the polyethylene fiber layer, thereby extending the service life of the flame retardant rope and further improving the use efficiency of the flame retardant rope.

[0016] 2. The utility model can prevent most flame retardant ropes from loosening during the winding process of low smoke and fire isolation through the setting of the limit component when the flame retardant rope is used, through the limit component set on the outside of the flame retardant rope body, which makes the winding of the flame retardant rope time-consuming and labor-intensive and increases the labor intensity, resulting in the situation that the use efficiency of the flame retardant rope is reduced. The support vertical rods are fixedly installed on both sides of the upper end of the workbench by fastening bolts, and the servo motor is fixedly installed on the upper part of the outer side of the support vertical rod with the fastening bolts. The output shaft of the servo motor is connected to the take-up roller through a coupling. The operation of the servo motor drives the take-up roller to rotate, so that the flame retardant rope connected to the outside of the take-up roller is wound up accordingly. The spring damping rod is fixedly installed in the middle of the upper end of the workbench through the mounting seat with the fastener, and the limit plate is fixedly installed on the upper end of the spring damping rod with the fastener. The limit plate is elastically connected to the take-up roller through the spring damping rod, and then when the take-up roller rotates to wind the flame retardant rope, the limit plate resists and limits the flame retardant rope, thereby preventing the flame retardant rope from loosening during the winding process, and further improving the convenience of the flame retardant rope during use.

At the same time, the polyetheretherketone layer 3 arranged inside the fire-retardant coating layer 2 has good flame retardancy and is difficult to burn under normal conditions. Even if it burns, the amount of smoke and the release of harmful gases are very low, thereby improving the safety of the flame-retardant rope during use. The flame-retardant fiber layer 4 arranged inside the polyetheretherketone layer 3 further improves the overall fireproofing of the flame-retardant rope. The polyethylene fiber layer 5 arranged inside the flame-retardant fiber layer 4 has polymerization properties and can expand rapidly at high temperatures to form an insulating layer, thereby preventing the spread of flames. Polyethylene fiber is one of the most widely used high-temperature flame-retardant rope materials in the current industrial field. The rope core body 6 is protected by the polyethylene fiber layer 5, thereby extending the service life of the flame-retardant rope and further improving the use efficiency of the flame-retardant rope.
