Description

[Technical Field]

[0001] The present invention relates to the technical field of electric power distribution line work tools, and more particularly to an intelligent stripper that can automatically recognize twists in wires. [Background technology]

[0002] Generally, wire strippers are divided into two types according to the application scenario: electrical work type and power interruption type. The former is used to strip live overhead circuits, while the latter is used to strip live wires. Correspondingly, the former has a more complex structure and is more difficult to design.

[0003] On the other hand, wire strippers can be divided into two main types according to the stripping method: rotary advance type and translation type. Conventional electric wire strippers generally use the rotary advance type.

[0004] For example, a Chinese utility model with the authorization publication number CN221126768U and the authorization publication date 2024.06.11 discloses a stripping device for high-altitude cable electrical work, which includes a clamping mechanism including a first cable clamp and a second cable clamp arranged in a synchronized back-and-forth motion or a back-to-back motion, a stripping mechanism, and a transmission mechanism including a second limit plate fixed to the other side of the first limit plate, wherein a plurality of transmission gears and a C-shaped gear having an opening are installed between the first limit plate and the second limit plate, a gear bridge is hingedly connected to the opening of the C-shaped gear, the gear bridge is arranged to move back and forth to close and open the opening of the C-shaped gear, and when the gear bridge closes the opening of the C-shaped gear, the C-shaped gear and the gear bridge form a complete circular gear, and a plurality of inclined screws are installed on the opposite sides of the first cable clamp and the second cable clamp, respectively.

[0005] The type of stripping device in this utility model belongs to the above-mentioned electrically operated type and rotary forward type, and the advantages of this stripping device are that it is easy to operate, has a short working time, has a high stripping efficiency, and does not damage the cable core.

[0006] However, when actually used, the peeling device has at least the following two drawbacks, which are also technical problems that the present invention aims to solve:

[0007] First, the parts that directly clamp the wire are the first and second cable clamps, and they are equipped with multiple inclined screws, allowing them to rotate and move forward. However, the friction between the clamps and the wire, and between the inclined screws and the wire, is sliding friction, which has a relatively larger friction force than rolling friction, making it easy for the wire to twist, which directly leads to the cable sheath not being able to be stripped properly, damages the core stripping, and indirectly leads to the cable breaking, and such accidents account for the majority of accidents during wire stripping work.

[0008] Second, the device lacks the necessary corresponding structure for detecting the wire twist phenomenon, which is extremely important, because during the wire stripping operation, the operator needs to be 2-3 meters away from the wire area, making it difficult to directly observe the wire twist phenomenon, and it generally takes only a few seconds from the start of the wire twist phenomenon to the complete cable breakage.

[0009] Therefore, in summary, there is currently an urgent need for a new intelligent stripper that can avoid wire twisting as much as possible and recognize early warnings when twisting occurs in the early stages. Summary of the Invention

[0010] The present invention provides an intelligent stripper that can automatically recognize wire twist. By installing an active rotating frame unit, a roller clamping unit, and a roller sensor on an opening translation gear, the following occurs: 1. When the roller clamping unit clamps the wire, the friction between them is rolling friction, and the friction force is relatively small, making it relatively difficult for the roller clamping unit to actively twist the wire; 2. When an unexpected twist occurs in the wire, the originally relatively stationary wire rotates together with the active rotating frame unit, and the relative rotation speed between it and the roller sensor decreases. The rotation speed reduction signal accurately recognizes the wire twist phenomenon and instructs the stripper to stop, thereby avoiding subsequent more serious wire peeling accidents.

[0011] The technical solution used by the present invention to solve the above problem is an intelligent stripper that can automatically recognize wire twist and has a structure including an opening translation gear for seating the wire, and further includes an active rotating frame unit that meshes with the opening translation gear, a roller clamp unit installed on the active rotating frame unit and clamps the wire, and drives the active rotating frame unit to move along the length direction of the wire when the active rotating frame unit rotates, and a roller sensor installed on the roller clamp unit and driven by the wire friction, and when the wire twists, the rotation speed of the roller sensor decreases.

[0012] As another preferred technical solution, the active rotating frame unit includes a vertical housing with both the bottom and sides open, two driven gears installed on the vertical housing and meshing with the open translation gear, an active gear installed on the vertical housing and meshing with the two driven gears, and a rotation motor installed on the vertical housing for driving the active gear.

[0013] As a further preferred technical solution, the active rotating frame unit further includes a gear rotation speed sensor installed on the vertical housing for detecting the rotation speed of the driven gear or the active gear.

[0014] As a further preferred technical solution, when a twist occurs in the wire, the ratio of the rotation speed of the roller sensor to the gear rotation speed detected by the gear rotation speed sensor becomes smaller.

[0015] As a further preferred technical solution, the roller clamp unit includes two opening fixing blocks respectively installed at both sides of the vertical housing, screws and guide rods installed on the two opening fixing blocks, two opening sliders installed to fit onto the guide rods and screwed onto the screws for clamping the wire, a tilting drive wheel installed on one of the opening sliders and clamping the wire, and a wire press wheel installed on the other opening slider, and the wire press wheel and roller sensor are installed on the same opening slider.

[0016] As a further preferred technical solution, the roller clamp unit further includes a bevel gear installed on the screw, and a wire clamp motor installed on the opening fixing block for driving the bevel gear.

[0017] As a further preferred technical solution, the roller clamp unit further includes a cutter housing, which is installed on one of the opening sliders and for mounting a peeling cutter.

[0018] As a further preferred technical solution, the vertical housing further comprises a main body housing for capping the rotation motor and for mounting a control circuit board.

[0019] As a further preferred technical solution, the aperture translating gear is provided with a second roller sensor for clamping the wire and recording the travel distance of the active rotating frame unit on the wire.

[0020] As a further preferred technical solution, the open translation gear is provided with a connector for attaching an insulating operating rod. [Brief explanation of the drawings]

[0026] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0027] As shown in Figures 1 to 7, an intelligent stripper can automatically recognize twists in a wire, and its structure includes an open translation gear 11 for seating the wire, an active rotating frame unit 1 that meshes with the open translation gear 11, a roller clamp unit 2 installed on the active rotating frame unit 1 and clamping the wire, driving the active rotating frame unit 1 to move along the length of the wire when the active rotating frame unit 1 rotates, and a roller sensor 3 installed on the roller clamp unit 2 and driven by wire friction, and when twists occur in the wire, the rotation speed of the roller sensor 3 decreases.

[0028] In this embodiment, when the intelligent stripper is attached to the wire, the opening of the opening translation gear 11 faces downward, and the intelligent stripper is "fitted" onto the wire facing downward, i.e., the wire is fitted into the opening translation gear 11 facing upward.

[0029] When the intelligent stripper operates normally, the opening translation gear 11 does not rotate but only translates laterally, and the active rotating frame unit 1 drives the roller clamp unit 2 to rotate with the opening translation gear 11. Therefore, the peeling cutter in the roller clamp unit 2 rotates and moves forward in a peeling manner.

[0030] Here, since the parts inside the roller clamp unit 2 for directly clamping the wire are all rollers, it has the advantage that the friction force between the roller and the wire is relatively small, making it difficult to actively twist the wire, which greatly reduces the occurrence of accidents such as failed stripping, core damage, and cable breakage.

[0031] However, because the wire itself is relatively fine, the rolling friction still drives the twisting of the wire, or the clamping strength of the insulating locking bar used for the wire is insufficient, the wire still twists, that is, the originally immobile wire rotates in the same direction as the roller clamp unit 2. In this case, the relative speed between the wire and the roller sensor 3 becomes small, and the roller sensor 3 outputs a rotation speed signal that is obviously reduced, so that the intelligent stripper has the function of automatically recognizing the twisting of the wire, which is very practical and safe.

[0032] In addition, the peeling cutter, roller sensor 3, and all the parts and accessories of the intelligent stripper can be commercially available or easily manufactured according to conventional technology, ensuring that the above basic functions of avoiding twist and recognizing twist can be effectively realized.

[0033] The active rotating frame unit 1 includes a vertical housing 101 that is open at both the bottom and sides, two driven gears 102 that are installed on the vertical housing 101 and mesh with the open translation gear 11, an active gear 103 that is installed on the vertical housing 101 and meshes with the two driven gears 102, and a rotation motor 104 that is installed on the vertical housing 101 and drives the active gear 103.

[0034] In this embodiment, the bottom opening of the vertical housing 101 serves to fit wires inside, and the side openings serve to mount the internal structure. After the gear structure is mounted, a vertical cover can be further fitted onto the vertical housing 101 to further protect the entire gear structure.

[0035] The reason why the number of driven gears 102 is set to two is as follows.

[0036] If the opening translation gear 11 has its own opening position and there is only one driven gear 102, the gear will easily get stuck in the opening position and will not move; on the other hand, by using the two driven gears 102 in conjunction with each other, at least one driven gear 102 will always be meshed with the opening translation gear 11, that is, it ensures that the active rotating frame unit 1 can rotate one complete revolution on the opening translation gear 11 and rotate continuously.

[0037] The active rotating frame unit 1 further includes a gear rotation speed sensor 105 installed on the vertical housing 101 for detecting the rotation speed of the driven gear 102 or the active gear 103 .

[0038] In this embodiment, the number of the gear rotation speed sensors 105 is 1 to 4, and they are commercially available products. The principle is to count the number of teeth passing through the detection area in a unit time, and finally obtain the rotation speed result.

[0039] Therefore, the teeth on the opening translation gear 11, the teeth on the driven gear 102, and the teeth on the active gear 103 can be used as the rotation speed detection object, and at this point, the intelligent stripper can obtain the rotation speed parameter.

[0040] When the wire is twisted, the ratio of the rotation speed of the roller sensor 3 to the gear rotation speed detected by the gear rotation speed sensor 105 becomes smaller.

[0041] In this embodiment, the first method for the intelligent stripper to automatically recognize the twist of the wire is to use the roller sensor 3 alone. The advantage of this method is that the detection method is simple, the number of parameters introduced is small, and the amount of calculation on the control circuit board is small. However, the disadvantage is that when the intelligent stripper rotates at a variable speed, the roller sensor 3 is likely to issue a false alarm, that is, its rotation speed reduction signal is an absolute signal without a reference quantity.

[0042] Meanwhile, the second method for the intelligent stripper to automatically recognize the twist of the wire is to use the roller sensor 3 in conjunction with the gear rotation speed sensor 105. The advantages and disadvantages of this method are opposite to those of the first method, and it is less likely to issue a false alarm even when the intelligent stripper moves forward while rotating at a variable speed, that is, the roller sensor 3 can be corrected using the rotation speed data of the gear rotation speed sensor 105.

[0043] The roller clamp unit 2 includes two opening fixing blocks 201 respectively installed at both sides of the vertical housing 101, screws 203 and guide rods 202 installed on the two opening fixing blocks 201, two opening sliders 204 installed to fit around the guide rods 202 and screw onto the screws 203 for clamping the wire, an inclined drive wheel 205 installed on one of the opening sliders 204 and clamping the wire, and a wire press wheel 206 installed on the other opening slider 204, and the wire press wheel 206 and roller sensor 3 are installed on the same opening slider 204.

[0044] In this embodiment, the opening fixing block 201 is screwed and fixed to the vertical housing 101, and the screw 203 has two screw segments with opposite rotation directions, so that when rotated as needed, the two opening sliders 204 move toward or away from each other, i.e., corresponding to the wire clamping operation before the peeling operation and the wire releasing operation after the peeling operation.

[0045] Here, as shown in FIG. 5, the rotation plane of the inclined drive wheel 205 is not perpendicular to the wire, but is inclined relative to the length direction of the wire, thereby propelling the entire intelligent stripper forward.

[0046] In addition, the rotation plane of the wire press wheel 206 is perpendicular to the wire and is mainly used to press the wire, so that a stable and constant peeling depth can be obtained on the wire as long as the peeling cutter itself does not move.

[0047] Finally, the number of the wire press wheels 206 is three, which are installed in combination with the roller sensor 3, and four rolling structures form two rows, so that the wire pressing action is more uniform and comprehensive. Meanwhile, the inclined drive wheels 205 are installed in two rows of three, and the central inclined drive wheel 205 is installed in a properly sunken position, so that all the inclined drive wheels 205 clamp the wire simultaneously and further drive the intelligent stripper forward effectively.

[0048] The roller clamp unit 2 is installed on one of the opening sliders 204 and further includes a cutter housing 209 for mounting a peeling cutter.

[0049] In this embodiment, the peeling cutter has an adjustable extension width in the cutter housing 209, that is, the cutter body can be used with a conventional ejector structure.

[0050] The vertical housing 101 is further provided with a main housing 4 for capping the rotation motor 104 and for mounting a control circuit board.

[0051] In this embodiment, all the parts and accessories can be commercially available, and the main body housing 4 is provided with heat dissipation holes.

[0052] The open translation gear 11 is further provided with a second roller sensor 5 for clamping the wire and recording the distance travelled by the active rotating frame unit 1 on the wire.

[0053] In this embodiment, the second roller sensor 5 is used to record the forward distance of the intelligent stripper. When the intelligent stripper is turned on, the required stripping length needs to be input or the previous default stripping length parameter needs to be used. After the second roller sensor 5 rotates to the required length, it can output a stop signal to the control circuit board.

[0054] Here, the second roller sensor 5 or its internal important sensor components may be commercially available products.

[0055] The open translation gear 11 is further provided with a connector 6 for attaching an insulating operating rod.

[0056] In this embodiment, when the intelligent stripper is used normally, the second roller sensor 5 is located between the operator and the wire, and the insulating operating rod 13 is located behind the wire. The insulating operating rod 13, like the opening translation gear 11, does not rotate but only translates, so the operator can always hold the insulating operating rod 13 and further stabilize the intelligent stripper.

[0057] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the present invention is not limited to the above embodiments, and various modifications may be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. These modifications are all non-inventive and are protected by the Patent Law as long as they fall within the scope of the claims of the present invention.
