Description

Technical Field

[0001] The invention relates to the technical field of wire stripping tools, in particular to a portable wire stripping device for live working. Background Art

[0002] At present, the insulation rate of distribution lines is very high, which brings certain difficulties to live wiring. Before live wiring, operators need to use stripping tools to strip the insulation layer of the insulated wire. There are two existing stripping methods. One is manual: the operator shakes the handle at the lower end of the insulating rod of the stripper on the pole tower to perform manual stripping; the other is electric: the operator holds the insulating rod of the stripper on the pole tower, and the personnel on the ground control the electric stripper to perform automatic stripping.

[0003] For example: Chinese patent application number 202211447664.3 discloses a manual cable stripper, including a driving screw, the threaded rod is provided with two threaded sections with opposite spiral directions, and both ends of the driving screw are provided with insulating gripping parts; a cable holding mechanism, the cable holding mechanism includes a guide rod parallel to the threaded rod and two cable holding blocks sliding along the guide rod, one threaded section is threadedly connected to one cable holding block, and the other threaded section is threadedly connected to the other cable holding block, the guide rod is fixed on the insulating holding part, and the two opposite side surfaces of the two cable holding blocks are provided with cable holding grooves, and the cable holding grooves pass through the cable holding blocks; a stripping knife, the stripping knife is fixed on one of the cable holding blocks; when the two cable holding blocks hold the cable tightly in the cable holding grooves of the two cable holding blocks, the blade of the stripping knife cuts into the insulating sheath of the cable.

[0004] Another example: Chinese patent application number 202311348913.8 discloses an automatic stripping tool for overhead insulated wires that can be used for live working, including an insulating shell and a power mechanism, an openable and closable gear, a linkage block and a blade arranged on the insulating shell. The two pressure blocks are controlled to move synchronously and in opposite phases by a bidirectional screw rod, thereby limiting the position of wires with different wire diameters; a blade adjustment mechanism is arranged on the outer wall of the pressure block, and a blade is arranged at the moving end of the blade adjustment mechanism. The blade adjustment mechanism is used to adjust the distance between the blade and the axis of the openable and closable gear, thereby facilitating the blade to strip wires with different wire diameters; the openable and closable gear, the gear positioning block, the linkage block, the pressure block, the blade adjustment mechanism and the blade are driven to rotate by the power mechanism, thereby realizing automatic stripping of the wire; the stripping tool itself is light in weight and easy to carry. It adopts an electric stripping method, which saves time and effort in operation, and can be used for stripping wires of different wire diameters, with a wide range of applicability.

[0005] The existing cable stripping equipment on the market, whether it is manual cable stripping equipment or electric cable stripping equipment, all perform stripping processing by rotating the stripping knife, and cannot accurately control the cable stripping length. Most of them rely on the workers' experience and only observe the cable stripping length by naked eyes. The stripping length has large error and poor accuracy. In actual application, it often causes the problem of stripping length being too long or too short, that is, it does not match the actual required stripping length. If the cable stripping length is shorter than the length required for the wiring operation, the workers have to perform a secondary stripping operation, which is time-consuming and labor-intensive, and has low construction efficiency, greatly delaying the construction process. If the cable stripping length is longer than the length required for the wiring operation, it will cause too much exposed part of the core conductor inside the cable, accelerate the aging of the core conductor and the service life of the cable. Therefore, the present application provides a convenient wire stripping equipment that can accurately control the stripping length. Summary of the invention

A stripping mechanism 6 and a cutting mechanism 7 are fixedly installed on the separated sides of the two L-shaped mounting frames 5. The stripping mechanism 6 is used to strip the insulation layer of the wire, and the cutting mechanism 7 is used to cut the stripped insulation layer.

The controller 8 is a controller 8 with information processing function, and the controller 8 has a microprocessor, has the ability to collect, process and exchange information, and can perform wireless information transmission with an external background terminal;

[0055] In actual application, through the coordinated use of the feeding mechanism 3, the stripping mechanism 6 and the cutting mechanism 7, the stripping length of the wire can be accurately controlled, and the stripping will not be too long or too short, so that the actual stripping length is the same as the required stripping length, avoiding a series of unnecessary troubles caused by stripping too long or too short, and ensuring the smooth progress of the workers' live fire-making operations.

[0056] The feeding mechanism 3 includes a servo motor 1 301, a mounting seat 1 302 and a mounting seat 2 303. The servo motor 1 301 and the mounting seat 1 302 are both fixedly mounted on the top of the U-shaped main frame 1, and the mounting seat 2 303 is fixedly mounted on the bottom of the U-shaped main frame 1. A threaded feeding rod 304 and a threaded guide rod 305 are movably inserted in the interiors of the mounting seat 1 302 and the mounting seat 2 303 respectively. The threaded feeding rod 304 and the threaded guide rod 305 are both fixedly connected to the U-shaped movable frame 4. The outer surface of the threaded feeding rod 304 is threadedly connected with a feeding nut 306. The outer surface of the feeding nut 306 is fixedly sleeved with a driven gear 307, and the outer surface of the driven gear 307 is meshed with a driving gear 308.

[0057] The outer surface of the threaded guide rod 305 is threadedly connected with a trigger block 309, and the front of the threaded guide rod 305 is marked with a scale line 3010. A mounting groove 3011 is provided on one side of the mounting seat 303 close to the trigger block 309. A touch switch 3012 is fixedly installed inside the mounting groove 3011. The touch switch 3012 is electrically connected to the controller 8.

[0058] The setting of the scale line 3010 on the threaded guide rod 305 facilitates the staff to accurately adjust the distance between the trigger block 309 and the U-shaped main frame 1, thereby ensuring the accuracy of the subsequent wire stripping length.

[0059] The output shaft of the servo motor 301 is coaxially fixedly connected to the driving gear 308 , and the feed nut 306 is rotationally connected to the mounting seat 302 .

[0060] The peeling mechanism 6 includes an electric telescopic rod 601 fixedly mounted on an L-shaped mounting frame 5, and a semicircular ring cutting knife 602 is detachably mounted on the telescopic end of the electric telescopic rod 601 through a disassembly assembly 12, and a peeling knife 603 is fixedly connected to the side of the semicircular ring cutting knife 602 away from the U-shaped movable frame 4.

[0061] The cutting mechanism 7 comprises an electric telescopic rod 701 fixedly mounted on the L-shaped mounting frame 5 , and a semicircular ring cutting knife 702 is detachably mounted on the telescopic end of the electric telescopic rod 701 through a disassembly assembly 12 .

[0062] The inner walls and both ends of the semicircular cutting knife 1 602 and the semicircular cutting knife 2 702 are provided with cutting edges. The end of the peeling knife 603 close to the semicircular cutting knife 1 602 and the end close to the semicircular cutting knife 2 702 are respectively fixedly connected with the triangular block 1 604 and the triangular block 2 605. The triangular block 1 604 is adapted to the cutting edge of the inner wall of the semicircular cutting knife 1 602, and the triangular block 2 605 is adapted to the cutting edge of the inner wall of the semicircular cutting knife 2 702. The peeling knife 603, the triangular block 1 604 and the triangular block 2 605 are provided with cutting edges at one end away from the L-shaped mounting frame 5 and the side close to the semicircular cutting knife 2 702. The peeling knife 603, the triangular block 1 604 and the triangular block 2 605 are integrally formed.

[0063] In actual application, through the setting of triangular block 2 605, when the semicircular ring cutter 2 702 cuts off the end of the required stripping position on the wire, the cutting edge position of the semicircular ring cutter 2 702 can be filled, so that when the two semicircular ring cutters 2 702 form a full-circle ring cutter, the triangular block 2 605 is in contact with the cutting edge of the semicircular ring cutter 2 702, avoiding that after the semicircular ring cutter 2 702 cuts off the end of the stripping position, the insulating layer cut into two semi-cylindrical shapes by the stripping knife 603 is adhered to a certain extent near the position of the semicircular ring cutter 2 702 due to the existence of the cutting edge of the semicircular ring cutter 2 702 (that is, the stripping knife 603 does not complete the cutting of the insulating layer at the cutting edge of the semicircular ring cutter 2 702), resulting in the risk of the stripped insulating layer hanging on the wire and being unable to detach.

[0064] Each set of disassembly and assembly components 12 includes an installation frame 1201, an installation block 1202 is movably inserted inside the installation frame 1201, a locking hole 1203 is opened on the front of the installation block 1202, and a locking pin 1204 is movably installed through the front of the installation frame 1201, one end of the locking pin 1204 is embedded in the locking hole 1203, and the other end of the locking pin 1204 is fixedly connected with a pull rod 1205, and a locking spring 1206 is fixedly connected between the pull rod 1205 and the installation frame 1201 and on the outer surface of the locking pin 1204, the installation frame 1201 is fixedly connected to the telescopic end of the electric telescopic rod, and the installation block 1202 is fixedly connected to the semicircular ring cutter. The installation frame 1201, the installation block 1202, the splint 205, the U-shaped main frame 1 and the U-shaped mobile frame 4 are all made of insulating materials to ensure the insulation performance of the equipment during use, so as to facilitate live work and wire stripping.

[0065] A device cavity 9 is opened on one side of the U-shaped main frame 1, and a lithium battery 10 is fixedly installed inside the device cavity 9. The lithium battery 10 is used to supply power to the servo motor and the electric telescopic rod, and an insulating hand-held rod 11 is also installed on the back of the U-shaped main frame 1.

[0066] Working principle: When it is necessary to perform live spark-cutting operation on an insulated wire, it is usually necessary to use a wire stripping device to strip the insulation layer on the surface of the insulated wire. The staff first determines the diameter of the core conductor inside the wire according to the specification model of the wire to be stripped, and replaces the semicircular ring cutter 1 602 and the semicircular ring cutter 2 702 accordingly;

[0067] When replacing the semicircular ring cutter, the worker first holds the pull rod 1205 and moves it to the side away from the installation frame 1201, driving the locking pin 1204 to move synchronously, and squeezes the locking spring 1206 to compress it and store energy, and continues to pull the pull rod 1205 until the locking pin 1204 completely withdraws from the locking hole 1203, thereby releasing the limit fixation of the installation block 1202, and then, takes the installation block 1202 out of the installation frame 1201, completing the disassembly of the installation block 1202, and indirectly realizing the disassembly of the semicircular ring cutter. Conversely, the installation block 1202 on the semicircular ring cutter with the same inner wall diameter as the core conductor diameter is inserted into the installation frame 1201, and the locking hole 1203 on the installation block 1202 is aligned with the installation frame 1 The locking pins 1204 on 201 are relatively positioned, and then the pull rod 1205 is loosened, and the locking pin 1204 is pushed into the locking hole 1203 by the elastic force of the locking spring 1206, and the mounting block 1202 is limited and fixed, so that the convenient replacement of the semicircular ring cutter can be completed. Each time the semicircular ring cutter is replaced, the outer size of the semicircular ring cutter is inconvenient, and only the semicircular ring cutters with different inner diameters are replaced to ensure that when the two electric telescopic rods 1 601 or the two electric telescopic rods 2 701 are extended to the longest state, the two semicircular ring cutters 1 602 or the two semicircular ring cutters 2 702 are just combined to form a full-circle ring cutter, and the inner wall diameter of the full-circle ring cutter is the same as the diameter of the core conductor, so as to ensure that the core conductor will not be cut when the wire is stripped;

[0068] When the semicircular ring cutter is replaced according to the specifications of the wire to be stripped, the worker adjusts the position of the trigger block 309 according to the stripping length of the wire required for the fire, and rotates the trigger block 309 to move it along the axial direction of the threaded guide rod 305, thereby adjusting the distance between the trigger block 309 and the U-shaped main frame 1 (in the subsequent stripping operation, the wire stripping length is: the distance between the trigger block 309 and the U-shaped main frame 1 + the distance between the semicircular ring cutter 1 602 and the semicircular ring cutter 2 702);

[0069] When the position adjustment of the trigger block 309 is completed, the worker holds the insulating hand-held rod 11 and sets the U-shaped main frame 1 and the U-shaped movable frame 4 on the outside of the wire to be stripped, and aligns the semicircular ring cutter 602 with the left end (starting end) of the position where the wire is to be stripped, and then sends an instruction to start the fixing mechanism 2 and the two electric telescopic rods 601 to the controller 8 through the external background terminal, and then starts the fixing mechanism 2 through the controller 8 to clamp and fix the U-shaped main frame 1 on the wire to be stripped. At the same time, the controller 8 starts the two electric telescopic rods 601 to extend them until the two electric telescopic rods 601 are extended to the longest state, thereby driving the two semicircular ring cutters 602 to move to the opposite side, and finally together form a full-circle ring cutter, which will The starting end of the wire to be stripped is cut off. At the same time, in the process of the semicircular ring cutting knife 602 cutting the insulation layer of the wire, the stripping knife 603, the triangle block 1 604 and the triangle block 2 605 are synchronously inserted into the insulation layer of the wire; then, an instruction to start the servo motor 301 is sent to the controller 8 through the external background terminal, and the output end of the servo motor 301 rotates clockwise, driving the driving gear 308 to rotate, and driving the driven gear 307 meshing with it to rotate synchronously, and when the driven gear 307 rotates, it can drive the feed nut 306 fixedly connected to the inner wall to rotate, and under the cooperation of the structures such as the threaded guide rod 305, the mounting seat 2 303 and the U-shaped moving frame 4, the threaded feed rod 304 is limited. The threaded feed rod 304 is used to move rightward along the axial direction of the feed nut 306 (i.e., move toward the end of the desired stripping position), thereby driving the U-shaped moving frame 4, the L-shaped mounting frame 5, the stripping mechanism 6, the cutting mechanism 7, the threaded guide rod 305 and the trigger block 309 to move synchronously. When the stripping mechanism 6 moves, the stripping knife 603 and the triangular block 2 605 in the two stripping mechanisms 6 cooperate to cut the insulating layer on the surface of the conductor into two semi-cylindrical shapes, and the insulating layer cut into semi-cylindrical shapes is separated from the core conductor under the thrust of the semi-circular ring cutter 1 602. When the trigger block 309 moves to abut against the touch switch 3012, the touch switch 3012 turns off the servo motor 1 301 (i.e., stops the stripping process). Then, an instruction to start the cutting mechanism 7 is sent to the controller 8 through the external background terminal, and the two electric telescopic rods 701 are started by the controller 8 to extend them to the longest state, driving the two semicircular ring cutters 702 to move to the opposite side, so that the ends of the two semicircular ring cutters 702 are in contact and together form a full-circle ring cutter, and the end of the wire to be stripped is cut off, so that the target stripping area on the wire can be precisely stripped. The stripping length of the wire in the above operation is: the distance between the trigger block 309 and the U-shaped main frame 1 + the distance between the semicircular ring cutter 1 602 and the semicircular ring cutter 2 702, and then by adjusting the distance between the trigger block 309 and the U-shaped main frame 1, the length of the wire stripping can be adjusted;

[0070] By setting the triangular block 605, when the semicircular ring cutter 702 cuts off the end of the required stripping position on the wire, the cutting edge position of the semicircular ring cutter 702 can be filled, so that when the two semicircular ring cutters 702 form a full-circular ring cutter, the triangular block 605 is in contact with the cutting edge of the semicircular ring cutter 702, to avoid that after the semicircular ring cutter 702 cuts off the end of the stripping position, the insulating layer cut into two semi-cylindrical shapes by the stripping knife 603 will be adhered to a certain extent near the position of the semicircular ring cutter 702 due to the existence of the cutting edge of the semicircular ring cutter 702 (that is, the stripping knife 603 does not complete the cutting of the insulating layer at the cutting edge of the semicircular ring cutter 702), resulting in the risk of the stripped insulating layer hanging on the wire and being unable to detach.

[0071] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the fixing mechanism 2 includes a fixing block 201 fixedly installed at the four corners of one side of the U-shaped main frame 1, wherein a bidirectional screw rod 202 is rotatably connected between two opposite fixing blocks 201, and a guide column 203 is fixedly connected to the other two opposite fixing blocks 201, and a guide ring 204 is movably sleeved on the outer surface of the guide column 203, and a clamping plate 205 is fixedly connected to the opposite side of the two guide rings 204, and a threaded block 206 is fixedly connected to the separated side of the two clamping plates 205, and the two threaded blocks 206 are both threadedly connected to the bidirectional screw rod 202, and a servo motor 207 is fixedly installed on one of the fixing blocks 201, and the output shaft of the servo motor 207 is coaxially fixedly connected to the bidirectional screw rod 202;

[0072] The wire to be stripped is placed inside the two clamps 205, and then a command to start the servo motor 207 is sent to the controller 8 through the external background terminal. The servo motor 207 is then started through the controller 8 to rotate its output end clockwise, driving the bidirectional lead screw to rotate. With the cooperation of the guide column 203, the guide ring 204 and the clamp 205 and other structures, the thread block 206 is limited, so that when the bidirectional lead screw rotates clockwise, the two thread blocks 206 move to the opposite side, thereby driving the two clamps 205 to move towards each other, clamping and fixing the wire, thereby clamping and fixing the U-shaped main frame 1 on the wire, completing the fixing of the stripping equipment on the wire, so as to facilitate the smooth progress of the subsequent stripping operation. After the stripping is completed, the output end of the servo motor 207 rotates counterclockwise, indirectly driving the two clamps 205 to move to the separated side, thereby releasing the clamping and fixing of the wire, so that the staff can remove the stripping equipment from the wire.
