Description

Technical Field

[0001] This utility model relates to the field of rope technology, specifically a spiral electric rope. Background Technology

[0002] Power ropes generally refer to ropes used in power transmission, construction, and maintenance. Power ropes can be categorized into insulated ropes, cable ropes, traction ropes, and hoisting ropes based on their different uses and characteristics. They are typically made of synthetic fibers, steel wire, and insulating materials. These ropes are specifically designed to bear the loads of electrical equipment, ensuring safety and efficiency. The advantages of power ropes include insulation, abrasion resistance, high strength, lightweight, corrosion resistance, flexibility, safety, and versatility. Spiral power ropes are a specially designed type of power rope, typically with a spiral structure. This design allows for a more even distribution of load when the rope is stretched, reducing localized stress concentration. They are also usually woven from multiple layers of materials, enhancing the rope's strength and abrasion resistance.

[0003] When a helical power rope is ready for use, it needs to be wound up and stored. Therefore, in addition to the rope body, the power rope also includes a winding machine for winding the rope. The structural reference model of the winding machine is the JT20 electrically controlled speed-regulating winch, which winds the power rope onto the drum for storage through the rotation of the internal drum. However, in existing power rope winding machines, the rope will irregularly slide on the outer wall of the drum during winding, resulting in the rope accumulating on one side of the drum. When the rope accumulation height exceeds the side of the drum, the rope will detach from the drum, leading to winding failure. To enable the rope to be evenly wound on the outer wall of the drum, a helical power rope is provided. Utility Model Content

[0004] The purpose of this invention is to provide a spiral electric rope to solve the problem mentioned in the background art where, when the existing electric rope winding machine is winding the rope, the rope will slide irregularly on the outer wall of the drum, resulting in uneven winding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral electric rope, including a frame, a winding roller rotatably mounted inside the frame, a rope body fixedly connected to the outer wall of the winding roller, and the winding roller rotating to cause the rope body to wind around the winding roller.

[0006] The guiding mechanism 3 includes a sliding frame, a reciprocating screw, and a guide wheel. The sliding frame is slidably installed inside the upper part of the machine frame, the reciprocating screw is rotatably installed inside the machine frame, and the reciprocating screw is located between the sliding frame and the winding roller. The guide wheel is rotatably installed on the upper part of the sliding frame.

[0007] The rope passes over the top of the guide wheel, and the reciprocating screw rotates to drive the sliding frame to slide back and forth inside the upper part of the frame. The reciprocating screw rotates synchronously with the winding roller, thereby driving the rope to be evenly wound on the outer wall of the winding roller.

[0008] As a preferred technical solution of this utility model, multiple crossbars are fixedly installed inside the frame, and the sliding frame is slidably sleeved on the outer wall of the crossbars.

[0009] As a preferred technical solution of this utility model, the outer side wall of the reciprocating screw has two staggered helical grooves, and the lower end of the sliding frame is rotatably connected to a slider, which is slidably installed in the helical groove of the reciprocating screw.

[0010] As a preferred embodiment of this utility model, two guide wheels are provided, and both guide wheels are rotatably connected to the upper end of the sliding frame.

[0011] As a preferred technical solution of this utility model, a motor for driving the winding roller to rotate is installed inside the frame, and the output shaft of the motor is driven by the winding roller through gears.

[0012] As a preferred technical solution of this utility model, the winding roller and the reciprocating screw both adopt gear transmission.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention solves the problem of uneven winding caused by the rope sliding irregularly on the outer wall of the drum during the winding of existing power rope winding machines. The rope passes over the top of the guide wheel, and the reciprocating screw rotates synchronously with the winding roller, thereby driving the rope to be evenly wound on the outer wall of the winding roller.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a spiral electric rope, including a frame 1, with the device being a JT20 electrically controlled speed-regulating winch. A winding roller 2 is rotatably mounted inside the frame 1. One end of the rope body 21 is fixedly connected to the outer wall of the winding roller 2. A motor 12 for driving the winding roller 2 to rotate is mounted on the frame 1. Figure 1 As shown, a first driven gear is rotatably connected to the side of the frame 1, and a driving gear is fixedly connected to the output shaft of the motor 12. After the motor 12 is started and drives the driving gear to rotate, the winding roller 2 can be driven to rotate through the first driven gear.

[0022] The motor 12 is started to drive the winding roller 2 to rotate, which winds the rope 21 onto the outer wall of the winding roller 2. However, when the rope 21 is wound around the outer wall of the winding roller 2, the rope 21 will move irregularly on the outer wall of the winding roller 2. When the rope 21 moves to the edge of the winding roller 2, the rope 21 will accumulate on one side of the winding roller 2. When it accumulates, the thickness of the rope 21 will increase rapidly. After the diameter of the rope 21 is larger than the diameter of the end face of the winding roller 2, the remaining part of the rope 21 will detach from the winding roller 2, resulting in winding failure. Therefore, in order to make the rope 21 evenly wound on the outer wall of the winding roller 2, a guide mechanism 3 is provided inside the upper part of the frame 1 to guide the winding of the rope 21.

[0023] The guiding mechanism 3 includes a sliding frame 31, a reciprocating screw 32, and a guide wheel 33, such as Figure 1 As shown, a crossbar 11 is fixedly installed inside the frame 1, and a sliding frame 31 is slidably sleeved on the outer wall of the crossbar 11. To prevent the sliding frame 31 from rotating, two crossbars 11 are provided. Two guide wheels 33 are provided, rotatably mounted on the upper end of the sliding frame 31, and the rope 21 passes over the two guide wheels 33. Figure 4As shown, the outer wall of the guide wheel 33 has an annular groove, and the outer wall of the rope 21 is engaged in the annular groove of the guide wheel 33. The guide wheel 33 prevents the rope 21 from contacting the outer wall of the sliding frame 31, thereby preventing the rope 21 from rubbing against the outer wall of the sliding frame 31 when it is wound, which would cause wear on the rope 21. The reciprocating screw 32 is rotatably installed in the frame 1, and the reciprocating screw 32 is located between the winding roller 2 and the sliding frame 31. The lower end of the sliding frame 31 is rotatably mounted with a slider 311. The outer wall of the reciprocating screw 32 has two staggered helical grooves. The slider 311 is slidably installed in the helical grooves. By rotating the reciprocating screw 32, the slider 311 slides in the helical grooves, thereby driving the sliding frame 31 to slide in the frame 1. After the slider 311 slides into the other helical groove, the sliding frame 31 moves in the opposite direction. The continuous rotation of the reciprocating screw 32 can drive the sliding frame 31 to slide horizontally and reciprocally in the frame 1. The reciprocating screw 32 is based on the reciprocating screw manufactured by Changzhou Sibite Machinery Manufacturing Co., Ltd. The sliding frame 31 slides back and forth, guiding the rope 21 to be evenly wound on the outer wall of the winding roller 2 through the guide wheel 33, preventing the rope 21 from accumulating and tangling.

[0024] The reciprocating lead screw 32 can be driven to rotate by a rocker arm, electric motor, or other drive components. To synchronize the rotation of the winding roller 2, for example... Figure 1 As shown, a linkage gear and a second driven gear are rotatably mounted on the outer side wall of the frame 1. One end of the reciprocating screw 32 passes through the side wall of the frame 1 and is fixedly connected to the second driven gear. The linkage gear meshes with the first driven gear and the second driven gear. After the motor 12 drives the first driven gear to rotate, the linkage gear drives the second driven gear to rotate, which in turn drives the reciprocating screw 32 to rotate.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
