Description

Technical Field

[0001] This invention relates to the field of conductor crimping technology, and more particularly to a power transmission and transformation conductor crimping device. Background Technology

[0002] Crimping of power transmission and transformation lines refers to the method of mechanically pressing the power transmission and transformation conductors to deform the steel core and aluminum wire within allowable limits, thereby achieving a tight connection. In the process of crimping power transmission and transformation conductors, a series of operations are required, such as cutting, stripping, inserting into conduits, and marking. Among these operations, ratchet shears or wire cutters are still used for cutting or stripping the wires. On the one hand, the work efficiency is low, and on the other hand, the clamping and fixing of the conductors is poor. The conductors are prone to displacement during the operation, and the cutting depth is difficult to control, which can easily damage the steel core of the conductors and affect the crimping quality. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The present invention will be described in one embodiment below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present patent. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0027] like Figure 1-2 As shown, this embodiment provides a power transmission and transformation conductor crimping device, including a rotating mechanism 1, a clamping mechanism 2, and a cutting mechanism 3. The clamping mechanism 2 is used to clamp the conductor 11 and position the conductor 11 to prevent the conductor 11 from shifting. The cutting mechanism 3 is used to cut and strip the conductor 11. The rotating mechanism 1 is disposed between the clamping mechanism 2 and the cutting mechanism 3, so that the cutting mechanism 3 can rotate around the conductor 11 to perform circumferential cutting on the conductor 11.

[0028] Specifically, such as Figure 3As shown, the rotating mechanism 1 includes two arc-shaped clamps 110 that are mated together. Connecting ears are provided on the mating surfaces of the two arc-shaped clamps 110, and mounting holes are provided on the connecting ears respectively. Bolts are installed in the mounting holes and matched with wing nuts to realize the installation of the two arc-shaped clamps 110. Among them, through holes 130 are provided at the relative positions of the two arc-shaped clamps 110. The cutting mechanism 3 is telescopically arranged in the through holes 130. By controlling the telescopic length of the cutting mechanism 3 in the through holes 130, the cutting depth of the wire 11 can be adjusted to avoid damaging the steel core of the wire 11. At the same time, several connecting frames 120 are provided on the inner walls of the two arc-shaped clamps 110. Preferably, two connecting frames 120 are provided on the inner wall of each arc-shaped clamp 110. Each connecting frame 120 is slidably connected to the clamping mechanism 2, so that the rotating mechanism 1 can rotate around the wire 11 clamped by the clamping mechanism 2, thereby realizing the circumferential cutting of the wire 11.

[0029] It should be noted that, as Figure 3 As shown, two arc-shaped clamps 110 installed together form a mounting frame. In this embodiment, it is preferable to use two arc-shaped clamps 110 to form a ring-shaped mounting frame, which facilitates the circumferential cutting of the conductor 11. Of course, it is also feasible to set the mounting frame to other shapes such as rectangle.

[0030] Furthermore, such as Figure 2 As shown, to improve the clamping effect on the wire 11 and thus increase work efficiency, the clamping mechanism 2 in this embodiment includes a clamping seat and a support base 230 for clamping the wire 11. To facilitate clamping wires 11 of different sizes and specifications, the clamping seat includes an upper clamping structure 210 and a lower clamping structure 220 that are mated together. That is, the clamping seat is designed as a split structure. The upper clamping structure 210 and the lower clamping structure 220 are also connected by bolts and wing nuts, so that the wire 11 is positioned between the upper clamping structure 210 and the lower clamping structure 220. Furthermore, to facilitate the inner wall of the clamping seat conforming to the shape of the wire 11, this embodiment preferably designs the upper clamping structure 210 and the lower clamping structure 220 as semi-circular structures to avoid damaging the wire 11. In this embodiment, the support base 230 is used for... Supported on the ground or other mounting platform, it supports the overall structure. The support base 230 is fixedly connected to the lower clamping structure 220. In order to facilitate the rotating mechanism 1 to perform circumferential cutting around the wire 11, in this embodiment, several connecting frames 120 are slidably connected to the clamping seat. Preferably, the outer walls of the upper clamping structure 210 and the lower clamping structure 220 are provided with sliding grooves 4, that is, the outer walls of the two semi-circular structures are respectively provided with sliding grooves 4 along the circumference. The two sliding grooves 4 are closed to form an annular groove. The connecting frame 120 is slidably disposed in the annular groove, thereby realizing the sliding of the connecting frame 120 in the annular groove, so that the mounting frame connected to the connecting frame 120 can rotate around the wire 11. The clamping seat is equivalent to the center of the mounting frame, and the connecting frame 120 is equivalent to the connection structure between the clamping seat and the mounting frame.

[0031] It should be noted that this embodiment can replace manual labor in fixing and positioning the wire 11 during the wire cutting, stripping, and crimping process, preventing the wire 11 from moving, maintaining the horizontality of the wire 11, ensuring the stability and convenience of the wire cutting, stripping, and crimping process, and saving manpower.

[0032] Furthermore, such as Figure 2 As shown, in order to improve the service life of the clamping seat, in this embodiment, a detachable clamping cylinder 6 is provided between the clamping seat and the wire 11. The clamping cylinder 6 is a two-half butt joint structure, and preferably the sliding groove 4 is provided on the outer wall of the clamping cylinder 6.

[0033] It should be noted that when the slide groove 4 on the clamping cylinder 6 breaks or when the slide groove 4 and the connecting frame 120 are repeatedly rubbed and worn, in order to facilitate the maintenance of the slide groove 4, improve the connection stability between the slide groove 4 and the connecting frame 120, and thus improve the connection stability between the mounting frame and the clamping seat, in this embodiment, it is preferable to provide a detachable clamping cylinder 6 between the clamping seat and the wire 11, and set the slide groove 4 on the outer wall of the clamping cylinder 6, so that only the clamping cylinder 6 can be replaced and maintained without disassembling and replacing the entire clamping seat, which is more convenient.

[0034] Preferably, the clamping cylinder 6 has multiple models with different inner hole sizes, so different sizes of wires 11 can be clamped, cut and stripped by changing the size of the clamping cylinder 6.

[0035] In one embodiment, such as Figure 3 As shown, in order to facilitate the sliding of the connecting frame 120 in the slide groove 4 and improve the smoothness of the mounting frame sliding around the clamping seat, in this embodiment, the end of the connecting frame 120 that is slidably disposed in the annular groove is provided with a roller 5.

[0036] Furthermore, such as Figure 4-5 As shown, in this embodiment, to facilitate cutting the wire 11, the cutting mechanism 3 includes a cutting frame and a blade 330. The cutting frame is telescopically disposed in the through hole 130, and the blade 330 is disposed facing the wire 11.

[0037] Specifically, such as Figure 4As shown, to facilitate control of the cutting depth of the cutter head 330 and to flexibly adjust its position for extension and retraction, the cutting frame includes a cutter holder 320 and a cutter handle. The cutter holder 320 is slidably connected to the through hole 130. The cutter holder 320 has internal threads, and the cutter handle has external threads. One end of the cutter handle is threadedly connected to the cutter holder 320, and the other end of the cutter handle extends out of the through hole 130. The cutter head 330 is fixed to the cutter holder 320 with screws. The outer wall of the cutter holder 320 has a limiting groove 8, and the inner wall of the through hole 130 has a protrusion. The protrusion is slidably disposed in the limiting groove 8 to limit the rotation of the cutter holder 320, i.e., when the operator... In use, hold the handle portion extending out of the through hole 130 and rotate the handle with the axis of the through hole 130 where the handle is mounted as the axis. The thread between the handle and the tool holder 320 drives the tool holder 320 to move along the axis of the through hole 130. The limiting groove 8 on the outer wall of the tool holder 320 and the protrusion on the inner wall of the through hole 130 restrict the rotation of the tool holder 320, thereby enabling the tool holder 320 to drive the cutting head 330 to move. This allows control of the cutting depth of the cutting head 330, that is, the rotational motion of the handle is converted into the linear motion of the cutting head 330, thereby controlling the cutting depth of the cutting head 330 on the wire 11.

[0038] Meanwhile, when circumferentially cutting the conductor 11, the operator can hold the handle and drive the mounting bracket to rotate around the clamping seat with the conductor 11 as the axis, which will drive the cutter head 330 to circumferentially cut the surface of the conductor 11.

[0039] Furthermore, in order to improve the smoothness of the tool holder's rotation within the through hole 130, in this embodiment, a rolling bearing 10 is provided at the entrance of the through hole 130. The outer ring of the rolling bearing 10 is interference-fitted with the through hole 130, and the inner ring of the rolling bearing 10 is interference-fitted with the tool holder.

[0040] Furthermore, such as Figure 3 As shown, in order to improve the service life of the mounting bracket, in this embodiment, a mounting cylinder 7 is provided in the two through holes 130 of the mounting bracket. The cutting bracket is telescopically arranged in the mounting cylinder 7. That is, the through holes 130 on the mounting bracket can be avoided by replacing the mounting cylinder 7. At the same time, when the wall thickness of the mounting bracket is too thin, the connection area between the cutting bracket and the mounting bracket can be increased by using the mounting cylinder 7, thereby improving the connection stability between the cutting mechanism 3 and the rotating structure.

[0041] Specifically, the mounting cylinder 7 is placed inside the through hole 130 of the mounting bracket. The inner wall of the mounting cylinder 7 is provided with screws, which are equivalent to protrusions on the inner wall of the through hole 130. The tool holder 320 is provided with a limiting groove 8. The screws cooperate with the limiting groove 8 to restrict the rotation of the tool holder 320 inside the mounting cylinder 7. The tool handle is threadedly connected to the tool holder 320, and the other end of the tool handle extends out of the mounting cylinder 7. A rolling bearing 10 is provided between the tool handle and the mounting cylinder 7. Therefore, when the tool handle is rotated, the tool holder 320 can make reciprocating linear motion inside the mounting cylinder 7, that is, drive the tool head 330 to make reciprocating linear motion, thereby realizing the control of the cutting depth of the wire 11.

[0042] It should be noted that in this embodiment, the rotational motion of the hand-twisting handle 310 is transformed into the linear reciprocating motion of the cutter head 330, which has the advantages of easy disassembly and assembly, simple structure and low manufacturing cost.

[0043] In one embodiment, such as Figure 4 As shown, in order to facilitate control of the cutting depth and avoid damaging the steel core during wire stripping, the outer wall of the knife holder 320 is provided with a scale 9.

[0044] Preferably, in this embodiment, the two arc-shaped clamps 110 are respectively provided with corresponding cutting mechanisms 3, that is, each of the left and right sides of the mounting frame is equipped with a cutting mechanism 3. The double-blade structure is used for cutting, which is convenient to operate and highly efficient. It can not only cut the outer aluminum stranded wire of the conductor 11, but also cut the conductor 11 as a whole, that is, realize the integration of wire stripping and wire cutting functions.

[0045] Preferably, in this embodiment, the cutter head 330 is configured as a circular blade structure, which helps to increase the cutting area of ​​the wire 11 and improve the cutting efficiency.

[0046] Working principle:

[0047] like Figure 6 As shown, when using this device, the wires 11 can be clamped by two power transmission and transformation wire crimping devices. When cutting the wires 11, the operator holds the handles 310 with both hands and turns the left and right handles 310 counterclockwise. This drives the cutter head 330 to make a linear feed motion, so that the two cutter heads 330 clamp the outermost aluminum stranded wire of the wires 11. Then, the operator rotates the handles 310 one revolution, which drives the rollers 5 on the connecting frame 120 to slide in the groove 4, so that the cutter head 330 makes a circumferential cut on the outermost aluminum stranded wire. The operator continues to turn the handles 310 counterclockwise to increase the cutting depth of the cutter head 330 on the wires 11. The operator then rotates the handles 310 to make a circumferential cut, cutting layer by layer until the steel core in the middle of the wires 11 is cut off, thus completing the cutting operation of the wires 11. Finally, the operator turns the handles 310 clockwise to drive the cutter head 330 to make a retraction action.

[0048] Simultaneously, after cutting the conductor 11, it is necessary to strip the conductor 11, that is, strip the aluminum wire to expose the inner steel core. At this time, when performing the stripping operation, first calculate the outer diameter of the remaining steel core to obtain the required cutting depth. The operator turns the left and right handles 310 counterclockwise, and the left and right cutter heads 330 clamp the outermost aluminum stranded wire. Then, the operator rotates the handles 310 one revolution with both hands, driving the rollers 5 on the connecting frame 120 to slide in the slide groove 4 to perform a circumferential cut on the outermost aluminum stranded wire. Continue to turn the handles 310 counterclockwise to increase the cutting depth, and then rotate the handles 310 to perform a circumferential cut, stripping the wire layer by layer. The cutting depth is controlled by reading the scale 9 on the cutter holder 320. When cutting the last layer of aluminum stranded wire, the cutting depth of the last layer of aluminum stranded wire needs to be adjusted to three-quarters of the diameter of the aluminum stranded wire. The remaining quarter is broken off by hand to avoid damaging the inner steel core during cutting, and the stripping operation is completed.
