Description

[0002] Cables are usually made of one or more mutually insulated conductors and an outer insulating protective layer. Their function is to transmit electricity or information from one place to another. The most basic requirements for cables are that they can be moisture-proof, insolation-proof, cold-resistant, heat-resistant, and UV-resistant. During the use of cables, some abnormalities may occur due to many reasons. When the cables are abnormal, they need to be repaired. Most of the existing cables are repaired by electricians after abnormalities occur.

In this process, if the cable is heavy, it will be difficult to connect. In the case of pulling, this will cause inconvenience in maintenance, and when connecting two sections of cable, the cable is prone to rebound, and the two sections of cable that are pulled close will move away, causing inconvenience in connection; in addition, when reconnecting the broken cable cores, since the cable cores usually have many cores and the multiple cable cores do not have the function of fixed separation, the multiple cable cores are easily entangled together, it is inconvenient to find the corresponding cable cores, and it is inconvenient to re-enter the connection when winding; therefore, it is very necessary to provide a low-voltage cable maintenance device and a method of use that has a reasonable structure, saves time and effort by mechanically pulling cables close, quickly separates cable cores, and is convenient for connection and maintenance.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings. Example 1

[0026] like Figure 1-9 As shown, a low-voltage cable maintenance device comprises an upper bracket 1 and a rear bracket 2 located behind the upper bracket 1, slideways 3 are arranged on the left and right sides of the inner side of the upper bracket 1, an I-shaped groove steel plate 4 is arranged inside the upper bracket 1, both ends of which are respectively slidably connected to the slideways 3, a group of fixed pulleys 6 are symmetrically arranged above the I-shaped groove steel plate 4, the fixed pulleys 6 are connected to a wire clamping power assembly 7 located above the upper bracket 1 through cables, so as to realize the up and down movement of the I-shaped groove steel plate 4 along the slideway 3; fixing clamps 5 are arranged on both sides of the I-shaped groove steel plate 4, the fixing clamps 5 are threadedly connected to a two-way pulling threaded rod 13 located inside the I-shaped groove steel plate 4, the two-way pulling threaded rod 13 adopts a screw driver 12 as a power source, so as to realize the movement of the fixing clamps 5 towards or away from each other along the I-shaped groove steel plate 4.

[0027] The fixing fixture 5 includes a movable frame 51 located inside the I-shaped groove steel plate 4, the movable frame 51 can move along the inner wall of the I-shaped groove steel plate 4 and the movable frame 51 is threadedly connected to the two-way pulling threaded rod 13, a group of symmetrically arranged link rods 52 are hinged at the bottom of the movable frame 51, the lower ends of the link rods 52 are hinged with clamping main rods 53, the inner upper parts of the clamping main rods 53 are provided with anti-slip angle plates 54, a locking spring hook 55 is provided at the hinge between one of the link rods 52 and the clamping main rod 53, and a locking rod is provided in front of the clamping main rod 53 corresponding to the locking spring hook 55.

[0028] The wire pulling clamping power assembly 7 includes a frame 71 with a trapezoidal structure, a switch 72 is installed on the upper part of the frame 71, a double-wheel winch 73 is arranged on the upper part of the frame 71, and wire wheels 74 are arranged on both sides of the frame 71. The double-wheel winch 73 is connected to the corresponding fixed pulley 6 through cables passing through the wire wheels 74.

[0029] In this embodiment, the working principle of the fixing clamp and the wire-pulling clamping power assembly is as follows: after a set of clamping main rods of the fixing clamp are sleeved on the outside of the cable, the switch is turned on to start the double-wheel winch, and the double-wheel winch connects the fixed pulley through the cable passing through the wire wheel, thereby driving the I-shaped groove steel plate to move upward along the slideway. In the process of the I-shaped groove steel plate moving upward, a set of connecting rods drives the hingedly connected clamping main rods to rotate and contract inward (close to each other), thereby clamping and fixing the cable; and because the fixing clamp is slidably connected to the inner side of the I-shaped groove steel plate through the moving frame, and the moving frame of the fixing clamp is connected to the two-way pulling thread The rod is threadedly connected, and the two-way pulling threaded rod is dynamically connected to the screw driver. Therefore, when the screw driver is started, the two-way pulling threaded rod can be driven to rotate by the screw driver, and the two-way pulling threaded rod drives the fixing clamps to move closer to or away from each other. Therefore, the positions of the fixing clamps on both sides can be adjusted by the screw driver and the two-way pulling threaded rod, and then the cable that is cut into two sections can be pulled closer to each other through the fixing clamp, which is convenient for manually connecting the cable that is cut into two sections, and the two sections of the cable can be pulled closer to each other with less effort, so as to facilitate the subsequent docking of the cables and facilitate maintenance.

[0030] A shaft rod 8 is installed inside the rear bracket 2, and three rotationally adjustable components 9 are installed on the shaft rod 8 in sequence from left to right. A hydraulic cutting component 10 is installed on the rotationally adjustable component 9 located in the middle of the shaft rod 8, and partition components 11 are installed on the rotationally adjustable components 9 located on both sides of the shaft rod 8.

[0031] The adjustable rotating component 9 includes a frame plate 91, a rotating bearing outer ring 92 is installed on the inner side of the frame plate 91, a fixed shaft ring 93 is arranged on the inner side of the rotating bearing outer ring 92, and a fixed bearing inner ring 94 is arranged inside the fixed shaft ring 93; a worm gear 95 is installed inside the rotating bearing outer ring 92, and a worm 96 is installed on one side of the worm gear 95.

[0032] In this embodiment, the working principle of the rotatable adjustable component is as follows: since the rotatable adjustable component is arranged on the outside of the shaft rod through the inner ring of the fixed bearing, the position of the rotatable adjustable component on the shaft rod can be adjusted, and then the position of the hydraulic cutting component and / or the separating component can be adjusted, so that the position of the hydraulic cutting component can be adaptively fine-tuned according to the position of the damaged cable to be cut off as needed, and then the position of the separating component can be fine-tuned according to the corresponding wiring requirements. After the position is adjusted, the inner ring of the fixed bearing is locked with the shaft rod through the fixed shaft rod, and then the worm gear is driven to rotate by the worm, and the worm gear drives the outer ring of the rotating bearing and the frame plate to rotate, thereby driving the hydraulic cutting component and / or the separating component to rotate to the upper cable, thereby realizing the cable cutting and / or supporting separation functions.

[0033] The hydraulic cutting assembly 10 includes a cutting frame 101, an upper cutting blade assembly 102 is arranged on the inner upper side of the cutting frame 101, short connecting rods 103 are arranged on the left and right sides above the upper cutting blade assembly 102, the short connecting rods 103 are connected by a long connecting rod 104, one end of the long connecting rod 104 is connected to the cutting frame 101 through a movable rod, and the other end is installed with a driving rod 105, the free end of the driving rod 105 is dynamically connected to a hydraulic cylinder assembly 106; a group of slide seats 107 are arranged on the left and right sides of the upper cutting blade assembly 102, and the slide seats 107 are slidably connected to the slide rails 108 located on the inner side of the cutting frame 101.

[0034] An upper cutting knife 201 is arranged at the lower part of the upper cutting knife assembly 102, a flat pressing plate 202 is arranged in front of the upper cutting knife 201, the flat pressing plate 202 is connected to the upper cutting knife assembly 102 through a plurality of spring rods 203, a movable side plate 204 is arranged above the flat pressing plate 202, the movable side plate 204 is evenly provided with a plurality of vertical grooves 205 from left to right, a positioning angle iron 206 is arranged above the movable side plate 204, and the positioning angle iron 206 is connected to the upper cutting knife assembly 102 through bolts penetrating the vertical grooves 205.

[0035] A lower cutting knife assembly 109 is arranged at the lower inner side of the cutting frame 101. The left end of the lower cutting knife assembly 109 is rotatably connected to the cutting frame 101 through an axle pin assembly 110, and the right end is detachably fixedly connected to the cutting frame 101 through a fixing bolt 120. A lower cutting knife 130 corresponding to the upper cutting knife 201 is arranged above the lower cutting knife assembly 109, and the lower cutting knife 130 is fixedly mounted on the lower cutting knife assembly 109 through a plurality of fixing blocks 140.

[0036] In this embodiment, the working principle of the hydraulic cutting assembly is as follows: after the hydraulic cutting assembly is driven to rotate to the upper cable by rotating the adjustable assembly, the fixing bolt is removed, the lower cutter assembly is rotated with the shaft pin assembly as the axis, and then the cable to be cut is placed under the upper cutter assembly, and then the lower cutter assembly is rotated to restore and locked with the fixing bolt, and the hydraulic cylinder assembly is started. The hydraulic cylinder assembly drives the slides on both sides of the upper cutter assembly to move down along the slide rail through the force transmission of the driving rod, the long connecting rod and the short connecting rod (ensuring that the upper cutter assembly moves smoothly and reliably, thereby ensuring the cutting of the cable Effect), the upper cutting knife of the upper cutting knife assembly cooperates with the lower cutting knife of the lower cutting knife assembly to cut the cable. When cutting the cable, the flat pressing plate first contacts the outer surface of the cable. As the cutting goes deeper, the flat pressing plate cooperates through the vertical groove and the screw rod located in the vertical groove and connected to the positioning angle iron, so that the flat pressing plate compresses the spring rod and moves upward as the cutting depth goes on. When the cutting is completed, the flat pressing plate recovers under the action of the spring rod. The flat pressing plate can effectively prevent the cable from warping during the entire cutting process, resulting in unsuccessful or uneven cutting, or even failure to achieve effective cutting.

[0037] The partition assembly 11 includes a shaft sleeve 111 , and a rotating sleeve 112 is rotatably mounted on both ends of the shaft sleeve 111 . A plurality of partition clamping plates 113 are disposed on the outer periphery of the rotating sleeve 112 .

[0038] In this embodiment, the working principle of the separation component is as follows: if it is necessary to connect multiple cable cores of the cable, first, the separation component is driven to rotate around the shaft to the upper cable by rotating the adjustable component; the multiple cable cores are respectively passed through different separation cards outside the rotating sleeve on one side, and then the rotating sleeve on the other side is rotated so that the positions of the separation cards through which the corresponding cable cores of the cables on both sides respectively pass correspond to each other; the corresponding cable cores on both sides are wound and connected, so that the different multiple cable cores can be separated regularly, the cable cores will not be entangled together, and the positions through which the corresponding cable cores of the cables on both sides respectively pass correspond to each other, so that the cables that need to be connected to each other can be found by finding the cables with corresponding positions on the two separation boards, so that the cables that need to be connected to each other are easy to identify; in actual use, when there are fewer cores, several separation cards (such as Fig. 9 As shown in the figure), the cables can be better separated; when there are many wire cores, all of them can be set as separation cards to further improve the separation effect.

[0039] The present invention is a low-voltage cable maintenance device and a method for using the same. During use, the fixing clamp 5 is clamped on the outside of the cable, and then the I-shaped groove steel plate 4 is driven to move up along the slideway 3 by the wire-pulling clamping power component 7, and then the cable is clamped and fixed by the fixing clamp 5; the hydraulic cutting component 10 is driven to rotate around the shaft 8 to the upper cable by rotating the adjustable component 9, and the damaged section of the cable is cut off by the hydraulic cutting component 10; the positions of the fixing clamps 5 on both sides are adjusted by the screw driver 12 and the bidirectional pulling threaded rod 13, so that the cable that is cut into two sections is pulled closer to each other by the fixing clamp 5; The cable that is cut into two sections is manually connected; if multiple cable cores of the cable need to be connected, first, the adjustable component 9 is rotated to drive the separation component 11 to rotate around the shaft 8 to the upper cable; multiple cable cores are respectively passed through different separation card plates 113 outside the rotating sleeve 112 on one side, and then the rotating sleeve 112 on the other side is rotated to make the positions of the separation card plates 113 passed through by the corresponding cable cores of the cables on both sides correspond to each other; the corresponding cable cores on both sides are wound and connected; the present invention has the advantages of reasonable structure, time-saving and labor-saving mechanical cable pulling, rapid separation of cable cores, and convenient docking and maintenance work.
