Description

Technical Field

[0001] The invention relates to the technical field of armored cable production, and in particular to a preparation device for an armored cable. Background Art

[0002] Armored cable is made of conductors of different materials installed in a metal sheath of insulating material and is processed into a flexible and solid combination. The mechanical protection layer of armored cable can be added to cables of any structure to increase the mechanical strength of the cable and improve its anti-corrosion ability. It is designed for areas that are susceptible to mechanical damage and extremely susceptible to erosion.

[0003] During the production of armored cables, after the protective steel belt is wound on the surface of the cable, the protective steel belt will produce a slight elastic reset after being deformed, so that the protective steel belt and the internal cable are not well fitted, affecting the protective effect of the armored cable. In addition, during the production of armored cables, when the cable is wound with the protective steel belt, the entire cable is in a conveying state parallel to the steel belt. However, due to the thick cable and the twist in some sections after winding, the entire cable is in an irregular swinging state. If the swing amplitude of the cable is large during continuous conveying, a large angle will be generated with the protective steel belt to be wound, which is not conducive to the adaptive winding of the protective steel belt on the cable.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Embodiment 1, refer to Figure 1-Figure 7 , a preparation device for an armored cable, comprising a processing seat 1 and a winding cover 2, a basic cable 3 is arranged in the winding cover 2, and a protective steel belt 4 is arranged above and below the basic cable 3, a driving motor 5 is connected to the top of the processing seat 1 through a mounting plate, and the driving motor 5 is connected to one end of the winding cover 2 through a gear assembly, and the upper and lower side walls of the other end of the winding cover 2 are connected to a winding roller 8 through a cutting disc 9, and a pre-winding component for pre-winding the protective steel belt 4 is arranged on the outer wall of the winding roller 8;

[0029] Further, the gear assembly is composed of a main gear 6 and a secondary gear ring 7, the main gear 6 is meshed with the secondary gear ring 7, the output end of the driving motor 5 is fixedly connected to the end of the main gear 6 through the driving shaft, the end face of the secondary gear ring 7 is fixedly connected to one end of the winding cover 2, the inner side wall of one end of the winding cover 2 is fixedly connected with a positioning ring, the outer side wall of the other end of the winding cover 2 is rotatably connected to the end of the winding roller 8 through a cutting disk 9, the protective steel belt 4 winding sleeve is arranged on the outer side wall of the winding roller 8, the pre-rolling assembly is composed of a preheating cover 10 and a preheating motor 11, the preheating cover 10 is arranged above the winding roller 8, the bottom end of the preheating motor 11 is fixedly connected to the top of the preheating cover 10, a tensioning roller 12 is arranged on one side of the winding roller 8, and a traction roller 13 is arranged below one side of the tensioning roller 12;

[0030] It should be noted that: the basic cable 3 is passed through the interior of the winding cover 2, and the basic cable 3 is continuously wound and advanced. At the same time, the protective steel belt 4 on the winding roller 8 is stably conveyed under the limit of the tensioning roller 12, and the winding roller 8 is pulled by the traction roller 13. During this process, the preheating motor 11 preheats the protective steel belt 4, and the protective steel belt 4 is easier to be bent and shaped. The protective steel belt 4 is pre-bent and wound, and then the driving motor 5 is started and the main gear 6 is driven to rotate through the driving shaft. The rotation of the main gear 6 will drive the meshing auxiliary gear ring 7 to rotate together. The rotation of the auxiliary gear ring 7 drives the entire winding cover 2 to rotate, so that the protective steel belts 4 on the two winding rollers 8 are alternately wound on the basic cable 3;

[0031] A further advantage of adopting the above method is that the protective steel belt 4 can be preheated before being wound around the basic cable 3, which facilitates the initial shaping before bending and winding, reduces the rebound of the protective steel belt 4 after being wound around the basic cable 3, and allows the protective steel belt 4 and the basic cable 3 to be wound more tightly.

[0032] Example 2, reference Figure 1-Figure 7 The outer side wall of the other end of the winding cover 2 is connected to a detection seat 15 through a plurality of horizontal rods 14, and a plurality of detection components are arranged on the inner side wall of the detection seat 15;

[0033] Furthermore, the detection assembly is composed of an arc plate 16 and a pneumatic piston rod 17. The multiple arc plates 16 are arranged in a circular shape. The outer wall of the arc plate 16 is fixedly connected to the output end of the pneumatic piston rod 17. The outer wall of the other end of the winding cover 2 is fixedly connected to the end of the detection seat 15 through the horizontal rod 14. The inner wall of the detection seat 15 is fixedly connected to a cavity ring 18. The other end of the pneumatic piston rod 17 is connected to the cavity ring 18. The outer wall of the detection seat 15 is fixedly connected to a pressure sensor 19.

[0034] It should be noted that: after controlling the swing amplitude of the basic cable 3 during its travel, if the swing amplitude of the basic cable 3 is extremely large, the basic cable 3 will press the arc plate 16 in the detection seat 15, and the arc plate 16 will press the pneumatic piston rod 17 when it is pressed, so that the air pressure in the cavity ring 18 increases, and the air pressure sensor 19 on the detection seat 15 will detect that the air pressure in the cavity ring 18 increases to the warning air pressure, indicating that the basic cable 3 still has a large swing amplitude under the condition of compensating for the swing amplitude, indicating that the basic cable 3 has an abnormal swing during its travel;

[0035] A further advantage of adopting the above method is that the air pressure sensor 19 can be used to monitor the air pressure in the cavity ring 18 to detect whether the basic cable 3 has abnormal large swings during its travel, so as to promptly remind the staff on site.

[0036] Example 3, reference Figure 1-Figure 7 A compensation seat 20 is disposed outside one end of the detection seat 15, a compensation ring 21 is disposed inside the compensation seat 20, the outer wall of the compensation ring 21 is connected to a pressure dividing tube 28 through a buffer component, and the inner walls of both ends of the pressure dividing tube 28 are respectively connected to compensation components through two guide rods 29;

[0037] Further, the end of the compensation seat 20 is fixedly connected to the end face of the detection seat 15 through a plurality of fixing rods, the outer wall of the compensation ring 21 is rotatably connected to the compensation rod 23 through the steering ball 22, the compensation assembly is composed of a compensation piston plate 24 and a damping plate 26, the end of the compensation rod 23 is fixedly connected to the end face of the compensation piston plate 24, the side wall of the compensation piston plate 24 is slidably connected to a T-tube 27, the inner wall of the T-tube 27 is fixedly connected to the side wall of the damping plate 26, the T-tube 27 is fixedly connected to the outer wall of the ends of the two guide rods 29 through a pressure dividing tube 28, the other end face of the compensation piston plate 24 is fixedly connected to the end of the damping plate 26 through a reset spring 25, the compensation assembly is composed of an electric push rod 30 and a compensation arc plate 31, the guide rod 29 is electrically connected to the electric push rod 30, the output end of the electric push rod 30 is fixedly connected to the outer wall of the compensation arc plate 31, and a conductive liquid and a control power supply are arranged in the pressure dividing tube 28;

[0038] It should be noted that: the basic cable 3 will pass through the compensation ring 21 during its movement. If the swing amplitude of the basic cable 3 during its movement is small, the basic cable 3 will press the compensation ring 21 from a certain direction, and the compensation ring 21 will apply a force in the direction of the compensation rod 23 through the rotation between the steering ball 22 and the compensation rod 23, and the compensation rod 23 will drive the compensation piston plate 24 to slide in the T-tube 27, and use the compensation piston plate 24 to press the return spring 25 on the damping plate 26, and pump the conductive fluid into the pressure dividing tube 28, thereby hindering the swinging trend of the basic cable 3 and reducing the swing amplitude of the basic cable 3. If the swing amplitude is too large, the conductive fluid pressed into the pressure dividing tube 28 will connect the two guide rods 29 to each other, thereby starting the electric push rod 30, and the electric push rod 30 will push the compensation arc plate 31 to the basic cable 3 in the front and back directions, reducing the swing amplitude of the basic cable 3;

[0039] A further advantage of adopting the above method is that the compensation rod 23 can be used to hinder the small swing of the basic cable 3 during its movement. When the swing amplitude is large, the compensation arc plates 31 at the front and rear ends are used to apply external force to reduce the swing amplitude, thereby controlling the swing amplitude of the basic cable 3 during its movement within a normal range.

[0040] When the present invention is in use, the basic cable 3 is passed through the interior of the winding cover 2, and the basic cable 3 is continuously wound and advanced. At the same time, the protective steel belt 4 on the winding roller 8 is stably conveyed under the limit of the tensioning roller 12, and the winding roller 8 is pulled by the traction roller 13. In this process, the preheating motor 11 preheats the protective steel belt 4, and the protective steel belt 4 is easier to be bent and shaped. The protective steel belt 4 is pre-bent and wound. Then the driving motor 5 is started and the main gear 6 is driven to rotate through the driving shaft. The rotation of the main gear 6 will drive the meshing auxiliary gear ring 7 to rotate together. The rotation of the auxiliary gear ring 7 drives the entire winding cover 2 to rotate, so that the protective steel belts 4 on the two winding rollers 8 are alternately wound on the basic cable 3. In this way, the protective steel belt 4 can be preheated before it is wound around the straight basic cable 3, which is convenient for preliminary shaping before bending and winding, and reduces the rebound of the protective steel belt 4 after it is wound around the basic cable 3, so that the winding of the protective steel belt 4 and the basic cable 3 is tighter.

[0041] The basic cable 3 will pass through the compensation ring 21 during its travel. If the swing amplitude of the basic cable 3 during its travel is small, the basic cable 3 will press the compensation ring 21 in a certain direction. The compensation ring 21 will apply a force in the direction of the compensation rod 23 through the rotation between the steering ball 22 and the compensation rod 23. The compensation rod 23 will drive the compensation piston plate 24 to slide in the T-tube 27, and the compensation piston plate 24 will press the return spring 25 on the damping plate 26, and the conductive fluid will be pumped into the pressure dividing tube 28, thereby hindering the swing tendency of the basic cable 3 and reducing the vibration. The swing amplitude of the small basic cable 3 is reduced. If the swing amplitude is too large, the conductive liquid pressed into the voltage divider tube 28 will connect the two guide rods 29 to each other, thereby starting the electric push rod 30, and the electric push rod 30 will push the compensation arc plate 31 to the basic cable 3 to reduce the swing amplitude of the basic cable 3. In this way, the compensation rod 23 can be used to hinder the small swing of the basic cable 3 during its movement. When the swing amplitude is large, the compensation arc plates 31 at the front and rear ends are used to apply external force to reduce the swing amplitude, so that the swing amplitude of the basic cable 3 during its movement is controlled within a normal range;

[0042] After controlling the swing amplitude of the basic cable 3 during its movement, if the swing amplitude of the basic cable 3 is extremely large, the basic cable 3 will press the arc plate 16 in the detection seat 15, and the arc plate 16 will be pressed to press the pneumatic piston rod 17, so that the air pressure in the cavity ring 18 increases. The air pressure sensor 19 on the detection seat 15 will detect that the air pressure in the cavity ring 18 increases to the warning air pressure, indicating that the basic cable 3 still has a large swing amplitude after compensating for the corrected swing amplitude, indicating that the basic cable 3 has an abnormal swing. In this way, the air pressure sensor 19 can be used to monitor the air pressure in the cavity ring 18 to detect whether the basic cable 3 has an abnormal large swing during its movement, so as to promptly remind the on-site staff.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
