Description

Technical Field

[0001] This invention relates to the field of cable straightening technology, and more specifically to a tensile cable and its processing method. Background Technology

[0002] Power cables are the medium used for transmitting and distributing electrical energy. With the modernization of cities and the development of industry in my country, various forms of power systems, such as urban underground power grids, power plant access and output lines, power supply for industrial and mining enterprises, and underwater power transmission networks, have been developing and expanding year by year. As an indispensable transmission medium, cables are used in an increasing amount in various power systems. More and more cables of different sizes and formats are produced for different purposes. Cables are usually transported using cable rollers. When cables are wound on cable rollers for too long, they develop a certain curvature. When the cable is pulled out of the cable roller, it will cause the cable to coil up, which will create great resistance to the cable laying and affect the construction efficiency. Therefore, there is a lack of processing methods in the current technology that can straighten the cable when it is pulled out of the cable roller. Summary of the Invention

[0008] Step 3: The straightening device continuously pulls the cable out of the winding roller and straightens the cable;

[0009] Step 4: Lay out the straightened cable;

[0010] Step 5: Replace the used winding rollers to complete the continuous cable laying.

[0011] Furthermore, the straightening device includes a frame, on which two supports I are fixedly connected, and two slide rails are fixedly connected between the two supports I.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following is in conjunction with the appendix Figure 1 Detailed description: A tensile cable and its processing method, the method comprising the following steps:

[0028] Step 1: Install the cable winding roller into the fixing device;

[0029] Step 2: Pull the cable out of the winding roller and pass it between the two extrusion rollers 203 at the lower end and the extrusion roller 203 at the upper end;

[0030] Step 3: The straightening device continuously pulls the cable out of the winding roller and straightens the cable;

[0031] Step 4: Lay out the straightened cable;

[0032] Step 5: Replace the used winding rollers to complete the continuous cable laying.

[0033] The following is in conjunction with the appendix Figure 2-6 In detail, the straightening device includes a frame 101, a bracket I 102, a slide rail 103, a slider I 104, and a sliding table 105. Two brackets I 102 are fixedly connected to the frame 101, and two slide rails 103 are fixedly connected between the two brackets I 102. Two sliders I 104 are slidably connected to each of the two slide rails 103, and the upper ends of the four sliders I 104 are fixedly connected to the sliding table 105.

[0034] Furthermore, the frame 101 serves as a support, providing installation space for the bracket I 102. The slide rail 103 consists of two cylindrical slide rails, and the slider I 104 has a circular hole I. The slide rail 103 is slidably connected in the circular hole I, and the four sliders I 104 support the sliding table 105.

[0035] The following is in conjunction with the appendix Figure 2-6 In detail, the tensile cable and its processing method include a straightening device that further comprises a bidirectional screw 106, a motor I 107, and a slider II 108. The bidirectional screw 106 is rotatably connected to two brackets I 102, and the motor I 107 is fixedly connected to the bracket I 102 at the front end. The output shaft of the motor I 107 is fixedly connected to the bidirectional screw 106. The lower end of the sliding table 105 is fixedly connected to the slider II 108, and the slider II 108 is threadedly connected to the bidirectional screw 106.

[0036] Furthermore, the bracket I 102 is provided with a shaft hole I, and a bidirectional screw 106 is rotatably connected in the shaft hole I. The motor I 107 is used to drive the bidirectional screw 106 to always maintain unidirectional rotation. The bidirectional screw 106 is a reciprocating screw, and the slider II 108 is a swashplate slider. When the motor I 107 continues to rotate in one direction, the bidirectional screw 106 pushes the slider II 108 to reciprocate on the bidirectional screw 106. The bidirectional screw 106 and the slider II 108 are set to ensure that the extrusion roller 203 is always aligned laterally with the cable pulled out on the winding shaft 405, preventing misalignment between the extrusion roller 203 and the cable on the winding shaft 405, which could cause the cable to break during the straightening process.

[0037] The following is in conjunction with the appendix Figure 2-6 In detail, the straightening device further includes a bracket II 201, a rotating shaft 202, and a pressing roller 203. Two brackets II 201 are fixedly connected to the sliding table 105, and three rotating shafts 202 are rotatably connected to the brackets II 201. Each of the three rotating shafts 202 is fixedly connected to a pressing roller 203.

[0038] Furthermore, the bracket II 201 provides support, and the rotating shaft 202 has three shaft holes II. The three rotating shafts 202 are rotatably connected in the three shaft holes II respectively. When the cable passes through the squeeze rollers 203, the squeeze rollers 203 bend the cable upward, so as to cancel the upward curvature caused by the cable being wound on the winding shaft 405 for a long time, thus straightening the cable.

[0039] The following is in conjunction with the appendix Figure 2-6 In detail, the straightening device further includes pulley I204 and belt I205. Pulley I204 is fixedly connected to both of the two rotating shafts 202 at the lower end, and belt I205 is drivenly connected to the two pulleys I204.

[0040] Furthermore, pulley I204 and belt I205 serve as transmission mechanisms to enable the two rotating shafts 202 and the extrusion roller 203 to rotate synchronously.

[0041] The following is in conjunction with the appendix Figure 2-6 In detail, the straightening device further includes a square shaft 301, a square hole shaft 302, a motor II 303, a pulley II 304, and a belt II 305. The square shaft 301 is rotatably connected to two supports I 102, and the square hole shaft 302 is rotatably connected to two supports II 201. The square shaft 301 and the square hole shaft 302 are slidably connected. The motor II 303 is fixedly connected to the support I 102 at the front end. The output shaft of the motor II 303 is fixedly connected to the square shaft 301. The pulley II 304 is fixedly connected to the square hole shaft 302. The pulley II 304 is fixedly connected to the rotating shaft 202 at the lower end. The two pulleys II 304 are driven by the belt II 305.

[0042] Furthermore, the bracket I102 has a shaft hole III, and the square shaft 301 is rotatably connected in the shaft hole III. The square hole shaft 302 has a square hole in its center, and the square shaft 301 is slidably connected in the square hole. During the sliding process of the square hole shaft 302 on the square shaft 301, the square shaft 301 can still drive the square hole shaft 302 to rotate. The motor II303 drives the square shaft 301 and the square hole shaft 302 to rotate. The square hole shaft 302 drives the squeeze roller 203 located at the lower end to rotate through the pulley II304 and the belt II305. The two squeeze rollers 203 located at the bottom are used to drive the cable forward.

[0043] The following is in conjunction with the appendix Figure 7-10 In detail, the straightening device further includes two fixing devices, each including a bracket Ⅲ401 and a support roller Ⅰ402. The bracket Ⅲ401 is fixedly connected to the frame 101, and two support rollers Ⅰ402 are rotatably connected to the bracket Ⅲ401.

[0044] Furthermore, the frame 101 serves as a support, providing rotation space for the support bracket Ⅲ401. Two shaft holes Ⅳ are opened on the support roller Ⅰ402, and the two support rollers Ⅰ402 are rotatably connected in the two shaft holes Ⅳ respectively.

[0045] The following is in conjunction with the appendix Figure 7-10 In detail, the straightening device further includes a rotating shaft 403, baffles 404 and a winding shaft 405. The rotating shaft 403 is rotatably connected to the two support rollers I 402. Two baffles 404 are fixedly connected to the rotating shaft 403, and the winding shaft 405 is fixedly connected between the two baffles 404.

[0046] Furthermore, the winding shaft 405 provides space for cable winding, and the baffle 404 limits the cable to prevent it from slipping off the winding shaft 405. The two support rollers I 402 are tumblingly connected to the rotating shaft 403 to support the bracket III 401, allowing the rotating shaft 403 to rotate on the bracket III 401.

[0047] The following is in conjunction with the appendix Figure 7-10 In detail, the straightening device further includes a bracket IV 406, a crossbar 407, a bracket V 408, and a support roller II 409. The bracket IV 406 is fixedly connected to the frame 101, the crossbar 407 is rotatably connected to the bracket IV 406, two brackets V 408 are fixedly connected to the crossbar 407, and the support roller II 409 is rotatably connected to the two brackets V 408.

[0048] Furthermore, bracket IV 406 provides support and rotation space for crossbar 407. Support roller II 409 limits the rotation shaft 403. Support roller II 409 and two support rollers I 402 fix the rotation shaft 403. When crossbar 407 is horizontal, the rotation shaft 403 is fixed. When crossbar 407 is raised, the rotation shaft 403 can be replaced.

[0049] The following is in conjunction with the appendix Figure 7-10 In detail, the straightening device further includes a bracket VI 501, a support arm I 502, a rotating frame 503, a support arm II 504, a bracket VII 505, and a telescopic rod 506. The bracket VI 501 is fixedly connected to the frame 101. The support arm I 502 is rotatably connected to the bracket VI 501. The rotating frame 503 is rotatably connected to the support arm I 502. The support arm II 504 is rotatably connected to the rotating frame 503. The support arm II 504 is rotatably connected to the crossbar 407. The bracket VII 505 is fixedly connected to the frame 101. The telescopic rod 506 is rotatably connected to the bracket VII 505. The movable end of the telescopic rod 506 is fixedly connected to the rotating frame 503.

[0050] Furthermore, when the telescopic rod 506 extends, it pushes the support arm I 502 to rotate counterclockwise. The support arm I 502, through the support arm II 504, pushes the crossbar 407 to rotate clockwise to a horizontal position, thus fixing the pivot 403. When the telescopic rod 506 shortens, it pushes the support arm I 502 to rotate clockwise. The support arm I 502, through the support arm II 504, pushes the crossbar 407 to rotate counterclockwise, thus unlocking the pivot 403. When the crossbar 407 is in a horizontal state, the support arm I 502 and the support arm II 504 are in a straight line, forming a self-locking mechanism to prevent the crossbar 407 from rotating.
