Description

Technical Field

[0001] The present invention relates to the technical field of waste metal recycling, and particularly to a device for dragging and separating steel-cored aluminum stranded wires. Background Art

[0002] With the improvement of China's economic capacity and industrial development level, electric power energy has become an indispensable part of human life, ranging from industrial production to daily life. The demand for high-voltage transmission lines is increasing day by day. Among them, due to the characteristics of simple structure, convenient erection and maintenance, low line cost, large transmission capacity, and being conducive to laying across special geographical conditions such as rivers and valleys, good electrical conductivity, sufficient mechanical strength, large tensile strength, and the ability to increase the distance between towers, etc., steel-cored aluminum stranded wires are mainly used for outdoor high-voltage transmission lines, which undoubtedly increases the demand for steel-cored aluminum stranded wires. At the same time, due to the complex outdoor working environment, such as the swing of overhead transmission conductors under the influence of wind, freezing, and other adverse environmental factors, fretting wear and fretting fatigue will occur; under the action of erosive media such as moisture, chemical gases, dust, and salt substances in the atmosphere, the overhead transmission conductors will corrode, become significantly brittle, and the tensile strength will be greatly reduced. Therefore, the service life of steel-cored aluminum stranded wires is greatly reduced, and a large number of steel-cored aluminum stranded wires are replaced every year, which intensifies the recycling pressure of waste steel-cored aluminum stranded wires and the production pressure of new cables. Since the internal steel core and the external aluminum wire are made of different materials, in order to improve the recycling efficiency and avoid environmental pollution and resource waste, it is necessary to separate the steel core and the aluminum wire to improve the recycling efficiency of steel-cored aluminum stranded wires.

[0003] Through research on current patents, it is found that, for example, the patent number "CN201721107211.0" discloses a steel-cored aluminum stranded wire disassembling and separating machine, which can only separate single-layer aluminum wires through reverse twisting and cannot achieve the automation of peeling multi-layer steel-cored aluminum wires; another example is that the patent number "CN201910522166.2" discloses a tangent machine for steel-cored aluminum stranded wires, which cuts the steel-cored aluminum stranded wires into small sections to achieve the preliminary separation of the steel core and the aluminum stranded wire, and then sucks out the steel core by magnetic force to achieve the final separation. Although it avoids the initial problem of stripping steel-cored aluminum wires, cutting the entire steel-cored aluminum stranded wire and separating the cut steel core and aluminum wire by strong magnetism will result in excessive energy consumption, especially for multi-layer aluminum wires. Therefore, there is an urgent need to design a device for dragging and separating steel-cored aluminum stranded wires with a higher degree of automation, especially to achieve the automation of peeling the outer aluminum wire of the steel core and fixing the steel core.

The pushing and guiding system 5 is located in front of the steel core winding system 3. A pressing system 4 is installed inside the steel core winding system 3. A transmission system 2 connected thereto is arranged behind the steel core winding system 3. The transmission system 2 is fixed on the frame 1;

[0029] The steel core winding system 3 includes a winding disc 31, a pneumatic rotary joint 32 and a transmission shaft 33. The winding disc 31 and the pneumatic rotary joint 32 are respectively arranged at both ends of the transmission shaft 33. The winding disc 31 is in a cylindrical shape. At least two rectangular notches are formed on the winding disc 31. A wedge-shaped arc c is provided for transition between adjacent rectangular notches;

[0030] When the whole device works: First, the aluminum wire layer on the outer layer of the steel core aluminum stranded wire is peeled off to expose the steel core in the middle; Second, the steel core is fed into the device. The pushing and guiding system 5 can push one end of the steel core into the rectangular notch of the winding disc 31, and the steel core is pressed by the internal pressing system 4. After pressing, the transmission system 2 drives the steel core winding system 3 to rotate, so that the steel core can be wound on the outer surface of the winding disc 31 to achieve dragging and separation.

[0031] As Figure 2 shown, the transmission system 2 mainly provides and transmits power for the device. Its main components include a motor 21, a reducer 22, a small belt pulley 23, a large belt pulley 24, and a V-belt. The motor 21 is installed on the frame 1 through bolt connection to provide power for the device. The output end of the motor 21 is connected to the input end of the reducer 22 through a coupling. The reducer 22 can reduce the rotation speed of the motor 21 and increase the torque of the output shaft of the reducer 22. A small belt pulley 23 is connected to the output end of the reducer 22. The small belt pulley 23 is connected to a large belt pulley 24 through a V-belt 25. The middle of the large belt pulley 24 is key-connected to the transmission shaft 33 of the steel core winding system 3;

[0032] When the transmission system 2 works: The motor 21 starts and transmits the torque to the small belt pulley 23 through the reducer 22.

[0033] AsFigure 3 , Figure 4 , Figure 5 As shown in Figure 5 , the steel core winding system 3 is used to wind the separated steel core and separate the steel core from the aluminum wire by dragging. The steel core winding system 3 includes components such as a winding disc 31, a pneumatic rotary joint 32, and a transmission shaft 33. The transmission shaft 33 is installed on the frame 1, which plays a role in transmitting power and providing an installation space for the gas pipeline; the transmission shaft 33 is a hollow stepped shaft, and one end of the stepped shaft is a square flange a, and the square flange a is connected to the winding disc 31 by bolts, thereby realizing the fastening connection between the transmission shaft 33 and the winding disc 31. The other end of the hollow stepped shaft is a circular flange b, and the circular flange b is connected to the pneumatic rotary joint 32 by bolts. In addition, the transmission shaft 33 is hollow, and the internal hollow can be used to provide a flow path for the gas leading to the cylinder.

[0034] As Figure 5 shown, the winding disc 31 is cylindrical, and the outer surface of the cylinder is used to wind and drag the steel core; a rectangular notch is provided on the outer surface of the winding disc 31, and the function of the rectangular notch is to allow the end of the steel core to pass through the winding disc 31 to prepare for the subsequent clamping system to clamp the steel core; a circular arc groove d is designed on the bottom surface of the rectangular notch of the winding disc 31, and the circular arc groove d is used to clamp the steel core and prevent the steel core from slipping, so as to prevent the steel core from loosening during the dragging process. In addition, a wedge-shaped arc c is used to transition between the rectangular notches of the winding disc 31, and the purpose of this design is to make the movement of the steel core more smooth when passing through the rectangular notch.

[0035] As Figure 3 shown, the pneumatic rotary joint 32 is connected to the transmission shaft 33, and the pneumatic rotary joint 32 mainly prevents the problem of winding of the air circuit part of the pressing cylinder 43 when the winding disc 31 rotates.

[0036] As Figures 6 to 10 shown, the pressing system 4 is used to press the steel core against the cylindrical surface of the winding cylinder, so as to further prevent the steel core from loosening during the winding and dragging process. The pressing system 4 includes a synchronous rotating plate 42, a pressing cylinder 43, and a guide plate 49.

The pressing cylinder 43 is provided at one end of the synchronous rotating plate 42 away from the guide plate 49. The piston connecting rod 44 of the pressing cylinder 43 is connected to a push seat 45. A guide pressing block 48 is provided on the guide plate 49, and the push seat 45 is fixed on the guide pressing block 48. An L-shaped connecting rod 46 is also provided on the guide plate 49, and both ends of the L-shaped connecting rod 46 are respectively connected to the guide pressing block 48 and the synchronous rotating plate 42 by pin pins 47. Pin pins 47 are provided, and the pin pins 47 at both ends of the L-shaped connecting rod 46 are respectively connected to the guide pressing block 48 and the synchronous rotating plate 42, and the guide pressing block 48 is installed on the guide plate 49;

[0038] As Figure 9 shown, the synchronous rotating plate 42 is hexagonal. By rotating itself, it drives the other 5 groups of pressing components to complete synchronous actions. Through holes are respectively arranged at the top corners of the hexagon, and the through holes are connected to the long rod part of the L-shaped connecting rod 46 through pins 47. Through holes are provided at both the long rod and the short rod ends of the L-shaped connecting rod 46, mainly to realize the connection between the synchronous rotating plate 42 and the guiding pressing block 48 and complete the transmission of actions. The short rod part of the L-shaped connecting rod 46 is connected to the guiding pressing block 48 through a pin 47.

[0039] As Figure 6 and Figure 9 shown, the sliding part of the guiding pressing block 48 is in the shape of an I-shaped groove, and an I-shaped groove is fitted with a guiding plate 49. The guiding pressing block 48 can realize radial sliding within the guiding plate 49, thereby realizing the function of the guiding pressing block 48 to slide and press the steel core. The outer side of the guiding pressing block 48 is flat and is used to press the steel core against the inner surface of the winding disc 31. The guiding pressing block 48 is connected to the pushing seat 45 through screws. The pushing seat 45 is composed of a bottom plate and two side plates, and through holes are provided on both side plates to facilitate the insertion of the piston connecting rod 44. The piston connecting rod 44 is cylindrical and is connected to the cylinder piston through thread fastening to realize the power transmission between the cylinder piston and the pushing seat 45.

[0040] As Figure 10 shown, the guiding plate 49 is sleeved on the central shaft 41 and is also connected to the guiding pressing block 48 through a radial guiding groove e. Radial guiding grooves e are provided at the top corners of the guiding plate 49, mainly to provide a guiding function for the guiding pressing block 48.

[0041] When the pressing system 4 works: after the pressing cylinder 43 is ventilated, the piston extends and drives the pushing seat 45 through the piston connecting rod 44. The pushing seat 45 drives the guiding pressing block 48 to move radially on the radial guiding groove e of the guiding plate 49, and presses the steel core against the cylindrical inner surface of the winding cylinder; while the pushing seat 45 is moving radially, it will drive the L-shaped connecting rod 46 through the pin 47. The L-shaped connecting rod 46 drives the synchronous rotating plate 42 to rotate around the central shaft 41 through the pin 47. The synchronous rotating plate 42 rotates to drive the other 5 groups of pressing components to press the steel core, preparing for the winding and dragging of the steel core.

[0042] As Figure 11As shown, the pushing and guiding system 5 can push the steel core through the wedge-shaped arc c on the winding disc 31 to the rectangular notch of the winding disc 31, and finally clamp it in the arc-shaped groove d. The guide rail 54 and the propulsion cylinder 56 are installed in parallel on the frame 1. The guide rail 54 plays a guiding role, and the propulsion cylinder 56 provides propulsion power. The guide rail 54 is internally matched with the slider 53. The upper part of the slider 53 is connected to the propulsion plate 55 by bolts. The upper part of the propulsion plate 55 is fixedly provided with a downward pressing cylinder 51, which provides downward pressing power. The downward pressing cylinder 51 is matched with the clamping jaw 52 through screw fastening. The jaw part of the clamping jaw 52 can press the steel core;

[0043] When the pushing and guiding system 5 works: the downward pressing cylinder 51 is connected to the air source, and the piston extends to drive the clamping jaw 52 to move downward to realize the downward pressing of the steel core. The propulsion cylinder 56 is connected to the air source, and the piston extends to drive the propulsion plate 55 to move to realize the propulsion of the steel core. Through the cooperation of the two cylinders, the steel core is pushed into the arc-shaped groove d of the winding disc 31 to prepare for the clamping of the steel core.
