[0002] With the growing demand for electricity across various industries, conventional single-type cables are no longer sufficient. Armored cables consist of conductors of various materials enclosed in an insulating metal sheath, formed into a flexible, rigid structure. This mechanical protective layer can be added to any cable structure to increase mechanical strength and improve corrosion resistance. It is designed for use in areas susceptible to mechanical damage and corrosion. It can be laid using any method and is particularly suitable for direct burial in rocky areas. Armored cables are generally used for fixed-layout power cables, essentially fixed in place and essentially immobile, transmitting electrical energy. In addition to these goals, armoring cables also enhance mechanical protection, such as tensile and compressive strength, and extend their service life.

[0053] like Figure 1-14 As shown, an armored pipe and cable production equipment includes a pipe threading platform 1, a traction machine 2 and a traction trolley 3. The pipe threading platform 1 and the traction machine 2 are arranged in sequence in a straight line. The traction trolley 3 is installed at the entrance end of the pipe threading platform 1. The right side of the traction machine 2 is the entrance end. An independent wire pay-off frame 4 is placed at the entrance end. An operation control box 5 is provided on one side of the pipe threading platform 1. The driving components on the traction machine 2 and the wire pay-off frame 4 are electrically connected to the operation control box 5.

[0054] Specifically, such as Figure 2-4 As shown, the pipe threading platform 1 includes a first frame 101, and the bottom of the bottom support leg of the first frame 101 is provided with an adjustable foot 102. The upper part of the first frame 101 is symmetrically provided with two groups of conveying components, and the traction trolley 3 is installed on the conveying component. When working, the conveying component drives the traction trolley 3 to move linearly to convey the fixed-length armored pipe to the pipe threading platform 1; two groups of armored pipe positioning components 106 are symmetrically provided on one side of the feeding end on the top surface of the first frame 101, and two groups of first guide components 107 are symmetrically installed on the side wall of the feeding end of the first frame 101; the traction trolley 3, the armored pipe positioning component 106 and the first guide component 107 form two symmetrically arranged armored pipe loading stations.

[0055] like Figure 2 、 4As shown in Figures 5 and 6, the conveying assembly includes a traction motor 108, a main rotating wheel 104, and a slave rotating wheel 105. The rotating shaft of the traction motor 108 is connected to the main rotating wheel 104 and drives the main rotating wheel 104 to rotate. The main rotating wheel 104 and the slave rotating wheel 105 are connected by a traction belt 103. The traction motor 108 is installed on the inner side of the first frame 101 and is located at one end of the discharge port. The main rotating wheel 104 and the slave rotating wheel 105 are installed at both ends of the outer side of the first frame 101. Specifically, the traction motor 108 is electrically connected to the operation control box 5. When the traction motor 108 is in operation, it starts to rotate the main rotating wheel 104, which drives the rotation of the slave rotating wheel 105 and the traction belt 103, thereby driving the linear movement of the traction trolley 3.

[0056] like Figure 8 As shown, the traction trolley 3 includes a traction connecting plate 301, a movable slider 302, a traction trolley lower plate 303 and a traction trolley pressure plate 304.

The movable slider 302 is connected to the wire rope, and the wire rope is connected to the linear motor for driving, and the linear motor is installed at the lower right end of the pipe threading platform 1. Specifically, during operation, the traction trolley 3 is driven by the traction belt 103 and moves from the right side to the left side of the pipe threading platform 1 to load the armored pipe. When the armored pipe is loaded to the required length, the traction motor 108 stops rotating and the traction trolley stops moving. When the cable threading operation is performed, the movable slider 302 generates a force in the opposite direction under the action of the linear motor and the wire rope, realizing the tension operation of the traction trolley 3, ensuring that the armored pipe remains in a straight line during the threading process, preventing deviation, and ensuring uniform extension of the pipe.

[0057] like Figure 7As shown, each set of armored tube positioning assemblies 106 includes a drive cylinder 106-1, a movable positioning plate 106-2, and a fixed positioning plate 106-3. The fixed positioning plate 106-3 and the drive cylinder 106-1 are both bolted to the first frame 101. The movable positioning plate 106-2 is slidably connected to the first frame 101. The working rod of the drive cylinder 106-1 is connected to the side wall of the movable positioning plate 106-2 and drives the movable positioning plate 106-2 away from or toward the fixed positioning plate 106-3.

Specifically, the drive cylinder 106-1 is electrically connected to the operation control box 5 and is controlled by corresponding buttons. The armored tube positioning assembly 106 is mainly used to lock and position the tail end of the armored tube after it is cut.

[0058] like Figure 9 、 10 As shown, the traction machine 2 includes a second frame 201, and an adjustment platform 202 and a traction bracket 203 are sequentially arranged above the second frame 201.

When the conveyor belts rotate synchronously in the opposite direction, the cable is conveyed forward through the cable guide frame 208 and then enters the armored pipe, completing the pipe assembly operation of the two.

[0060] Specifically, the first sliding assembly includes a first slider 210 and a first guide rail 211 that match each other, the first slider 210 is connected to the bottom surface of the traction bracket 203, and the first guide rail 211 is connected to the top surface of the adjustment platform 202 by screws; the second sliding assembly includes a second slider 212 and a second guide rail 213 that match each other, the second slider 212 is connected to the bottom surface of the adjustment platform 202 by screws, and the second guide rail 213 is connected to the top surface of the working platform of the second frame 201 by screws; the arrangement direction of the first slider 210 and the first guide rail 211 is perpendicular to the arrangement direction of the second slider 212 and the second guide rail 213, and the sliding direction of the first slider 210 is the same as the moving direction of the cable, the traction bracket 203 slides along the first guide rail 211 to approach or move away from the pipe threading platform 1, and the adjustment platform 202 slides along the second guide rail 213 to align one by one with the two armored pipe loading stations on the pipe threading platform 1.

[0061] Specifically, such as Figure 12 As shown, the first guide assembly 107 and the second guide assembly 209 are identical, each comprising two mutually perpendicular guide rods. Each guide rod has a waist-shaped hole, each of which is equipped with two guide bearings. The two guide rods are positioned and connected to the corresponding frame via a mounting plate. The first guide assembly 107 provides positioning and guidance during armored tube loading, while the second guide assembly 209 primarily provides positioning and guidance during cable threading.

[0062] like Figure 10 As shown, the cable guide frame 208 includes a guide tube 208-1 at the top and a guide bracket 208-2 at the bottom. The bottom of the guide bracket 208-2 is connected to the traction bracket 203. The guide tube 208-1 is located at the top center of the guide bracket 208-2, and the height of the guide tube 208-1 is aligned with the conveyor belt on the lower rotating mechanism 204. The guide tube 208-1 is a hollow pipe, and the cable passes through the inner hole of the guide tube 208-1 during operation.

[0063] like Figure 11 As shown, the pay-off stand 4 includes a pay-off motor 401, a shaft 402, a limit cylinder 403, and a shift fork 404. The cable is coiled around the shaft 402, the center hole of which is connected to the telescopic rod of the limit cylinder 403. One end of the shift fork 404 is connected to the pay-off motor 401, and the other end of the shift fork 404 extends into a positioning hole on a side baffle of the shaft 402. When the pay-off stand 4 is in operation, the pay-off motor 401 is connected to the shift fork 404 via a connecting frame. During operation, the shift fork 404 drives the shaft 402 to rotate to achieve the pay-off or take-up operation. This structure is conventional technology and will not be described in detail here.

Specifically, in one embodiment, the displacement device 6 includes a lifting plate at the top and a lifting motor at the bottom. When receiving the armored tube, the lifting plate is in a high position. After the armored tube slides onto the lifting plate, the lifting plate is driven downward by the lifting motor. When it falls close to the storage rack, the armored tube rolls onto the storage rack. The displacement device can be adopted according to the actual usage situation. The armored tubes that have been armored can also be promptly transferred to the next workstation or storage rack through a robotic arm or other auxiliary mechanism.

[0068] Step 3: Loading the armored tube. The traction motor 108 is started to drive the main rotating wheel 104 to rotate via the rotating shaft. Since the main rotating wheel 104 and the slave rotating wheel 105 are connected by the traction belt 103, the traction belt 103 and the traction trolley 3 installed above are driven to move horizontally and linearly, that is, the armored tube is driven from the right to the left to the first rack 101. When it reaches the preset position, it automatically stops. Then, the operator at the inlet end cuts the armored tube and fixes the tail end of the armored tube to the armored tube positioning assembly 106.

[0069] Step 4: Straightening the armored tube: Start the traction trolley 3 by operating the control box 5, and the traction trolley 3 begins tension operation; the linear motor starts to drive the movable slider 302 to move along the matching slideway toward the outlet end, stretching and straightening the armored tube;

[0070] Step 5: Trim the pipe opening of the armored pipe. The operator at the inlet end trims the pipe opening at the tail end of the armored pipe, removes burrs and smoothes sharp edges.

[0071] Step 6: The cable is crimped and a crimp joint is made on the inserted end of the cable. The crimp joint is required to be smaller than the original outer diameter of the cable after crimping and have a chamfered front end.

[0072] Step 7: Adjust the traction machine. Loosen the positioning piece of the adjustment platform 202. Slide the adjustment platform 202 along the second guide rail 213 to align with the armored pipe loading station on the pipe threading platform 1. Tighten the positioning piece.
