Description

Technical Field

[0001] This invention belongs to the field of power construction tools technology, specifically relating to an adjustable substation secondary cable high-efficiency and safe stripping auxiliary tool and method. Background Technology

[0002] Secondary cables refer to cables used for control, signal transmission, and feedback. Examples include motor operating column control cables, metering, protection, and electrical communication cables. Secondary cables are the transmission medium for analog quantities such as current and voltage, as well as status quantities such as opening and closing commands, in the secondary systems of substations. Generally, the initial construction and commissioning of a conventional 110kV substation with two main transformers requires approximately 400 secondary cables with 2-12 cores. The renovation and upgrading of older secondary equipment requires approximately 180 secondary cables. Taking the renovation and upgrading as an example, each... Each cable head requires stripping approximately 2 meters of secondary cable at one end. For 180 cables, 360 secondary cable heads need to be made, resulting in a stripping distance of 180 cables × 2 meters × 2 ends = 720 meters. This is one of the most demanding tasks in secondary cable renovation, being both time-consuming and labor-intensive. Typically, workers use utility knives or similar tools to cut open the secondary cable sheath, which is not only inefficient but also prone to hand injuries. Therefore, we propose a portable and efficient secondary cable stripping tool. Summary of the Invention

[0003] The purpose of this invention is to provide an efficient and safe auxiliary tool and method for stripping secondary cables in adjustable substations, aiming to solve the problems mentioned in the background art.

[0011] Furthermore, the dimensions of the multiple first pressure grooves are different, the lengths of the cutting blades in the multiple cutting mechanisms are different, and each cutting blade can contact and cut the cable sheath that is squeezed and fixed in the corresponding first pressure groove and second pressure groove when it descends to the lowest position.

[0014] Compared with the prior art, the present invention has the following technical effects: 1) This invention utilizes the telescopic adjustment of an electric telescopic rod to drive the movement of the rotating shaft and connecting frame, firmly clamping the insulating plate seat onto the terminal block, forming a mechanical lock. This avoids the risk of traditional continuous panels closing due to vibration or accidental contact, providing a stable fixing effect. The elastic buckle mechanism has a limit buckle and an insulating elastic frame inside. Through the cooperation of a hydraulic cylinder and a pull rod, the insulating locking elastic buckle is tightly fastened to the insulating isolation observation window shell, further enhancing the overall stability. Compared with traditional open continuous panels or adhesive tape, the dual fixing mechanism ensures that the isolation cover will not fall off under various working conditions, reducing accidental contact incidents. At the same time, the installation and disassembly process is convenient, requiring no special tools, thus improving work efficiency. 2) The anti-accidental contact insulating cover of this invention is made of rubber or plastic insulating material, which effectively solves the problem of incomplete sealing by insulating tape. The cover body covers all exposed parts of the terminals, and the insulating layer is attached to the side of the insulating plate seat by clamping and clamping. This avoids insulation failure caused by aging, wear or poor adhesion of the tape. The inside of the insulating isolation observation window shell is equipped with a test wire insertion channel, and the outside is equipped with an insulating dust cover to prevent environmental factors such as dust and moisture from affecting the insulation performance. The insulating dust cover automatically closes when the test wire is inserted or removed to prevent the metal head from accidentally touching the terminal. This achieves continuous insulation in dynamic operation, reduces the risk of leakage and electric shock, improves the safety and reliability of secondary operation, and meets the strict requirements of substations for insulation measures.

[0015] 3) This invention ensures that the isolation cover firmly covers the terminal block through the locking and fixing mechanism and the elastic buckle mechanism, completely blocking the path of accidental contact and avoiding electric shock to the operator due to accidental contact with the exposed terminals. The test wire insertion channel on the insulating isolation observation window is equipped with an insulating dust cover, which automatically closes when not in use to prevent metal tools or test wire ends from accidentally touching the terminals. The limiting mechanism and the shrinkage adjustment mechanism allow the terminal spacing to be adjusted. Through the cooperation of the guide rod, the lifting seat and the rubber electric suction roller, the static electricity generated by the terminals is absorbed, reducing the risk of tangling and leakage.

It is not only fully functional but also simple to use and easy to carry.

[0033] Example 2 like Figures 1-15 As shown, an adjustable substation secondary cable high-efficiency and safe stripping auxiliary tool includes a housing 1. The top of the housing 1 has a sliding groove, and a lower mold 2 is slidably installed in the sliding groove. The top surface of the lower mold 2 has several first pressing grooves 3. The top of the housing 1 is rotatably installed with a pressing cutter assembly 4 that cooperates with the lower mold 2. The bottom of the housing 1 has an installation groove 5, and a limit component 6 and a guide cutter assembly 7 are installed in the installation groove 5. There are multiple limit components 6, and the guide cutter assembly 7 is located between multiple limit components 6. A fixing component 8 that fixes the cable end is fixedly installed at one end of the housing 1. Openings 9 that pass through the installation groove 5 are opened on both sides of the bottom of the housing 1. A cutting component 10 is installed at one of the openings 9. A protective shell 11 is snapped onto the bottom of the housing 1. A handle 12 is fixedly connected to one side of the housing 1.

[0034] In this embodiment, the extrusion cutter assembly 4 includes a top plate 41 rotatably mounted on the top of the housing 1. The surface of the top plate 41 has multiple through first strip-shaped holes 42. The bottom end of the top plate 41 is connected to an upper mold 43 by bolts. The surface of the upper mold 43 has multiple through second strip-shaped holes 44. The first strip-shaped holes 42 and the second strip-shaped holes 44 correspond one-to-one. The bottom ends of the upper mold 43 are provided with second pressure grooves 45 that correspond one-to-one with the first pressure grooves 3. The first strip-shaped holes 42 and the second strip-shaped holes 44 correspond one-to-one with the first pressure grooves 3. A mounting bracket 46 is slidably mounted on the surface of the top plate 41. An upper fixing plate 47 is integrally provided in the middle of the mounting bracket 46. The fixing plate 47 is attached to the surface of the top plate 41. Multiple cutting mechanisms 48 are mounted on the surface of the fixing plate 47. The multiple cutting mechanisms 48 are respectively arranged in the corresponding first strip-shaped holes 42.

[0035] Specifically, by rotating the top plate 41, the first pressure groove 3 on the surface of the lower mold 2 is exposed, and then the secondary cable is placed in the first pressure groove 3. After that, the top plate 41 is rotated down. At this time, the first pressure groove 3 and the second pressure groove 45 can effectively press the secondary cable in the first pressure groove 3 and the second pressure groove 45. The first strip-shaped through hole 42 and the second strip-shaped through hole 44 allow the cutting mechanism 48 to extend to the bottom and contact the surface of the secondary cable. Then, the sliding mounting bracket 46 allows the fixing plate 47 to drive the cutting mechanism 48 to cut the surface of the secondary cable.

[0036] In this embodiment, the limiting component 6 includes two connecting plates 61 fixedly installed in the mounting groove 5. Two first grippers 62 and second grippers 63 are rotatably mounted between the two connecting plates 61 and are hinged to each other. The head ends of the first grippers 62 and the second grippers 63 are rotatably mounted with clamping plates 64. When the two clamping plates 64 are closed, they form a limiting part with the space between the first grippers 62 and the second grippers 63. A first adjusting block 65 is rotatably mounted at the middle curved part of the first gripper 62, and a second adjusting block 66 is rotatably mounted at the tail end of the second gripper 63. The middle parts of the first adjusting block 65 and the second adjusting block 66 are provided with adjusting screw holes, and a first adjusting screw 67 is threaded into the adjusting screw holes of the first adjusting block 65 and the second adjusting block 66.

[0037] Specifically, the operator inverts the auxiliary tool, removes the protective shell 11, and then rotates the first adjusting screw 67 to open the first clamp 62 and the second clamp 63 under the action of the first adjusting block 65 and the second adjusting block 66. The secondary cable is then placed between the first clamp 62 and the second clamp 63. The operator then rotates the first adjusting screw 67 in the opposite direction to close the clamp plate 64, thereby confining the secondary cable within the limiting part formed by the space between the clamp plate 64 and the first clamp 62 and the second clamp 63. The guide cutter assembly 7 then drives the secondary cable forward to cut the outer sheath of the secondary cable, thus facilitating efficient stripping of the secondary cable sheath.

[0038] In this embodiment, the guide cutter assembly 7 includes a fixed frame 71 fixedly installed in the mounting groove 5. The fixed frame 71 is hollow in the middle. A rotating rod 72 is rotatably installed on the top of the fixed frame 71. A guide wheel 73 is fixedly installed on the middle surface of the rotating rod 72. A guide groove is opened on the surface of the guide wheel 73 and a protrusion 74 is provided on the surface of the guide groove. One end of the rotating rod 72 extends through the outer shell 1 to the outside. The end of the rotating rod 72 outside the outer shell 1 is fixedly connected to the crank handle 75. Vertical guide rail grooves 76 are opened on both inner walls of the fixed frame 71. A U-shaped seat 77 is provided at the bottom of the guide wheel 73 in the middle of the fixed frame 71. A slider is fixedly connected to both sides of the U-shaped seat 77. The slider is slidably installed in the guide rail groove 76. A cutting wheel 78 is rotatably installed in the U-shaped seat 77. A second adjusting screw 79 is threadedly installed at the bottom end of the fixed frame 71. One end of the second adjusting screw 79 extends to the middle of the fixed frame 71 and is rotatably connected to the bottom end of the U-shaped seat 77.

[0039] Specifically, after the secondary cable passes through the limiting component 6, its end is placed between the cutting wheel 78 and the guide wheel 73. Then, the second adjusting screw 79 is rotated so that the U-shaped seat 77 moves the cutting wheel 78 to fit the outer sheath of the secondary cable. The second adjusting screw 79 is continuously rotated so that the top of the secondary cable can be moved into the guide groove of the guide wheel 73. The protrusion 74 provided can increase the friction with the outer sheath of the secondary cable. The operator can crank the handle 75, which drives the rotating rod 72, so that the guide wheel 73 can move the secondary cable forward. Under the action of the cutting wheel 78, the secondary cable can be driven forward by the guide wheel 73 while the outer sheath is cut by the cutting wheel 78. In this way, the cutting wheel 78 will not come into contact with the operator's hand, thus avoiding hand injury.

[0040] In this embodiment, the cutting mechanism 48 includes a support frame 481 fixedly installed on the surface of the fixed plate 47. A pressing block 482 is rotatably installed on the top of the support frame 481. The bottom of the pressing block 482 is rotatably connected to one end of the connecting rod 483. The other end of the connecting rod 483 is rotatably connected to the top of the guide rod 484. A guide block 485 is fixedly connected to the bottom of the front side of the support frame 481. The guide rod 484 is slidably connected to the guide block 485. An insertion hole is opened on the surface of the fixed plate 47. The bottom end of the guide rod 484 passes through the insertion hole and extends into the first strip-shaped through hole 42 and is fixedly connected to the base plate 486. A knife holder 487 is fixedly installed at the bottom end of the base plate 486. A cutting blade 488 is fixedly connected to the bottom end of the knife holder 487. A handle 489 is installed on one side of the pressing block 482.

[0041] Specifically, the operator rotates the lower pressure block 482 by using handle 489. The lower pressure block 482, together with the connecting rod 483 and guide rod 484, forms a linkage structure. Therefore, the connecting rod 483 will drive the guide rod 484 to descend. The guide block 485 can improve the stability of the guide rod 484 during descent. When the guide rod 484 descends, it will drive the base plate 486 to descend. At this time, the blade holder 487 will drive the cutting blade 488 to penetrate into the first strip-shaped through hole 42 and the second strip-shaped through hole 44 and contact the secondary cable sheath. The sliding mounting bracket 46 allows the fixing plate 47 to drive the cutting blade 488 to cut the secondary cable sheath pressed in the first pressure groove 3 and the second pressure groove 45, thereby facilitating the stripping of the secondary cable. In this way, the cutting blade 488 will not come into contact with the operator's hand, thus avoiding hand injury.

[0042] In this embodiment, the fixing component 8 includes a vertical plate 81 fixedly installed at one end of the housing 1, side plates 82 integrally provided on both sides of the vertical plate 81, and a support plate 83 integrally provided at the top of the two side plates 82. The surface of the support plate 83 is provided with a mounting hole 84, and a first pressing plate 85 is fixedly installed in the mounting hole 84. The side wall of the side plate 82 is provided with a through first strip groove 86. The front end of the support plate 83 is rotatably installed with a pressing mechanism 87. The pressing mechanism 87 cooperates with the first pressing plate 85 to press and fix the cable end. The surface of the vertical plate 81 is provided with a first through groove 88 and a second through groove 89. The circular pressing groove formed by the first pressing groove 3 and the second pressing groove 45 is aligned with the first through groove 88, and the second through groove 89 is aligned with the mounting groove 5.

[0043] Specifically, since the circular grooves formed by the first pressure groove 3 and the second pressure groove 45 are aligned with the first through groove 88, the secondary cable cut by the cutting blade 488 can move forward and enter the fixing component 8 through the first through groove 88. Then, the compression mechanism 87, in conjunction with the first compression plate 85, can press and fix the secondary cable that has moved forward into the fixing component 8. The secondary cable is pressed and fixed by the compression mechanism 87 and the first pressure groove 3 and the second pressure groove 45, thereby effectively improving the fixing effect of the secondary cable. Therefore, this method can improve the stability of the cutting blade 488 in cutting the secondary cable sheath, thereby improving the cutting effect of the secondary cable sheath.

[0044] In this embodiment, the extrusion mechanism 87 includes two pressure rods 871 that are rotatably mounted on both sides of the front end of the support plate 83. A connecting plate 872 is integrally mounted on the front end of the two pressure rods 871. The tail end of the pressure rod 871 is rotatably connected to one end of the linkage rod 873. A second extrusion plate 874 is provided between the two vertical plates 81. A plurality of protrusions 875 are provided on the surface of the second extrusion plate 874. Limiting blocks 876 are fixedly connected to both sides of the second extrusion plate 874. The two limiting blocks 876 are respectively disposed in the corresponding first strip groove 86. The other ends of the two linkage rods 873 are rotatably connected to the corresponding limiting blocks 876.

[0045] Specifically, after the secondary cable enters between the two side plates 82 through the first through groove 88, the operator presses down the pressure rod 871. Therefore, under the action of the linkage rod 873, the limiting block 876 rises along the first strip groove 86. At this time, the limiting block 876 drives the second extrusion plate 874 to move upward and cooperate with the first extrusion plate 85 to press the secondary cable. The protrusion 875 set on the surface of the second extrusion plate 874 can enhance the pressing effect on the secondary cable.

[0046] In this embodiment, the cutting assembly 10 includes a cutting plate 101 fixedly installed in one of the openings 9. A U-shaped groove 102 is formed on the surface of the cutting plate 101. A first cutter 103 is fixedly connected to one side of the U-shaped groove 102. A guide plate 104 is fixedly connected to the front side of the cutting plate 101, located away from the first cutter 103. A moving groove 105 is formed on the inner side of the guide plate 104. A moving plate 106 is slidably installed in the moving groove 105. A blade groove is formed on the inner side of the front end of the plate. A second cutter 107 is fixedly installed in the blade groove. A shaft hole 108 is formed on the surface of the guide plate 104, penetrating the moving groove 105. A circular clearance groove 109 is provided at the shaft hole 108. A power shaft 110 is inserted into the shaft hole 108. A circular power plate 111 is fixedly connected to one end of the power shaft 110 in the moving groove 105. A power block 112 is fixedly provided at the eccentric position of the power plate 111. The power plate 111 is set in the clearance groove 109. A second strip groove 113 is provided on the surface of the moving plate 106. The power block 112 is set in the second strip groove 113. A connecting block 114 is fixedly connected to the other end of the power shaft 110. A vertical rod 115 is fixedly provided on the surface of the connecting block 114. One end of the vertical rod 115 is rotatably connected to the power arm 116.

[0047] Specifically, when the worker needs to cut the cable, the worker passes the secondary cable through the U-shaped groove 102 and extends it through another opening 9. When the cutting length of the secondary cable is reached, the worker pushes the lever arm 116 to make the upright 115 drive the connecting block 114 to rotate. The connecting block 114 drives the power shaft 110 to rotate, and when the power shaft 110 rotates, it drives the power plate 111 to rotate. The power block 112 is set in the second strip groove 113 of the moving plate 106. Therefore, the power block 112, in conjunction with the second strip groove 113, can drive the moving plate 106 to move laterally in the moving groove 105. Thus, the first cutter 103 and the second cutter 107 can effectively cut the secondary cable.

[0048] In this embodiment, the dimensions of the multiple first pressure grooves 3 are different, and the lengths of the cutting blades 488 in the multiple cutting mechanisms 48 are different. When the cutting blades 488 in each cutting mechanism 48 descend to the lowest position, they contact the cable sheath that is squeezed and fixed in the corresponding first pressure groove 3 and second pressure groove 45 and cut the cable sheath.

[0049] Specifically, this method allows each cutting mechanism 48 to contact the outer sheath of secondary cables of different sizes within the corresponding first and second pressure grooves 3 and 45, thereby making it easier to cut the secondary cables.

[0050] In this embodiment, a U-shaped rod 15 is rotatably mounted on one end of the top plate 41. When the U-shaped rod 15 is fastened to the bottom of the outer shell 1, the top plate 41 is pressed against the top of the outer shell 1.

[0051] Specifically, after the top plate 41 is rotated down, it is fastened to the bottom of the outer shell 1 by the U-shaped rod 15. The U-shaped rod 15 can limit and fix the top plate 41, so as to avoid the top plate 41 from being lifted and affecting the cutting effect of the secondary cable during the secondary cable cutting. After rotating the U-shaped rod 15 to release the limitation on the top plate 41, the top plate 41 can be rotated to expose the first pressure groove 3 on the surface of the lower mold 2.

[0052] In this embodiment, vertical guide grooves 13 are provided on both sides of the slide groove at the end of the outer shell 1 away from the upright plate 81. Guide blocks are slidably installed in both guide grooves 13, and a stop rod 14 is fixedly connected between the two guide blocks. When the guide block is at the bottom of the guide groove 13, the stop rod 14 is located in the middle of the lower mold 2. When the guide block is at the top of the guide groove 13, the stop rod 14 is located at the top of the lower mold 2.

[0053] Specifically, after the guide block is slid upward so that the stop bar 14 is at the top of the lower mold 2, the lower mold 2 can be quickly replaced because it is slidably installed in the groove. The upper mold 43 is connected to the top plate 41 by bolts, allowing the operator to replace the upper mold 43 with the lower mold 2 that meets the specifications of the secondary cable to be stripped. After the stop bar 14 is released, the stop bar 14 can limit the lower mold 2 under the action of gravity, preventing the lower mold 2 from shifting and affecting the stripping effect of the secondary cable.

[0054] Example 3 The method for cable processing using an adjustable substation secondary cable high-efficiency and safe stripping auxiliary tool includes the following steps: 1. Steps for simultaneous stripping of multiple cables Step S11: Rotate upward to open the top plate 41 of the extrusion cutter assembly 4, exposing the lower mold 2 and the multiple first pressure grooves 3 on its surface.

[0055] Step S12: Place the multiple secondary cables that need to be stripped into the first pressure grooves 3 of different sizes on the lower mold 2 according to their outer diameter.

[0056] Step S13: Rotate downwards to close the extrusion cutter assembly 4, so that the second pressing groove 45 at the bottom of the upper mold 43 and the first pressing groove 3 of the lower mold 2 together press and fix the multiple cables.

[0057] Step S14: Press down the handles 489 of each cutting mechanism 48 on the extrusion cutter assembly 4 in sequence, so that each cutting blade 488 descends and cuts into the sheath of the corresponding cable.

[0058] Step S15: Slide the mounting bracket 46 along the cable axis to drive all the cutting blades 488 to move synchronously and cut all the sheaths of the compressed cable in one go.

[0059] Optionally, step S16 may also be included: during the stripping process, the pressure rod 871 of the fixing component 8 may be pressed down, and the cable end may be further fixed by the cooperation of the second pressing plate 874 and the first pressing plate 85 to enhance stability.

[0060] 2. Single-strand cable guide stripping procedure Step S21: Invert the entire tool and remove the protective shell 11 at the bottom to expose the limiting component 6 and the guide cutter component 7 in the mounting slot 5.

[0061] Step S22: Rotate the first adjusting screw 67 of the limiting component 6 to open the first clamp 62 and the second clamp 63. After inserting a single cable, rotate the adjusting screw in the opposite direction to clamp and fix the cable through the clamp and the clamp plate 64.

[0062] Step S23: Rotate the second adjusting screw 79 of the guide cutter assembly 7 to drive the U-shaped seat 77 and the cutting wheel 78 to rise until the cutting wheel 78 presses into the cable sheath to the required cutting depth, while the top of the cable is embedded in the guide groove of the guide wheel 73.

[0063] Step S24: Continuously crank the handle 75 to drive the guide wheel 73 to rotate, and use friction to move the cable forward. During this process, the fixed cutting wheel 78 continuously cuts the sheath of the moving cable in a circumferential manner.

[0064] 3. Cable Cutting Procedure Step S31: Keep the tool upright, insert the cable to be cut through the opening 9 on one side, pass it through the U-shaped groove 102 of the cutting assembly 10, and exit through the opening 9 on the other side.

[0065] Step S32: When the cut position mark on the cable moves to be aligned with the first cutter 103 and the second cutter 107, stop pulling the cable.

[0066] Step S33: Move the power arm 116 to drive the power plate 111 to rotate via the power shaft 110. The power block 112 on the power plate 111 moves in the second slot 113 of the moving plate 106, thereby driving the moving plate 106 and the second cutter 107 on it to move toward the fixed first cutter 103.

[0067] Step S34: The first cutter 103 and the second cutter 107 work together to cut the cable like scissors.
