Description

Technical Field

[0001] The invention relates to the technical field of cable strippers, in particular to an electric cable stripper. Background Art

[0002] Live working performed using an insulated operating rod is generally referred to as an indirect working method. This significantly improves safety and reliability by preventing contact between personnel and live equipment. The insulated overhead line insulation stripper is a crucial tool for live working.

[0003] Existing products primarily rely on manual operation, requiring replacement of the stripper blade mold to accommodate cables of varying diameters. However, these existing products present numerous challenges. First, stripping the outer insulation layer of a cable is inherently laborious, especially for thicker overhead cables with thicker outer insulation. Second, existing applications rely on fixed stripper blade molds to accommodate varying cable specifications. This can affect the quality of the stripping process if the cable diameter is non-standard or the outer layer is deformed due to weather. Furthermore, manual stripper operation requires constant manual adjustment of the blade depth based on the cable diameter and outer insulation material. Cutting too deep can damage the conductor, while insufficient cutting depth can prevent the stripping process. Summary of the Invention

DETAILED DESCRIPTION

[0038] The present invention aims to solve the technical problems in the prior art that it is difficult to perform electric stripping on cables of different specifications and difficult to monitor the stripping depth of the cables, and provides an electric cable stripper.

[0039] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 5 An embodiment of the present invention provides an electric cable stripper, comprising: a rotating mechanism 1, a linkage rod 3, a hanging base 4, a power transmission rod 5, a control unit 6 and a power supply unit 2. The rotating mechanism 1 is connected to the hanging base 4 through the linkage rod 3; the hanging base 4 is connected to the control unit 6 through the power transmission rod 5. The power supply unit 2 is electrically connected to and supplies power to the rotating mechanism 1 and the control unit 6 respectively; the control unit 6 communicates wirelessly with the rotating mechanism 1. In this embodiment, the power supply unit 2 comprises: a first plug-in battery 21 and a second plug-in battery 22. The first plug-in battery 21 is inserted into the battery holder socket of the rotating mechanism 1; the second plug-in battery 22 is inserted into the battery holder socket of the control unit 6. The rotating mechanism 1 and the control unit 6 are independently powered and wirelessly networked, and the operation of the rotating mechanism 1 is controlled by the control unit 6.

[0041] In the embodiment of the present invention, see Figure 1-Figure 5The rotating mechanism 1 includes a rotating housing, an upper cable clamp 15, a lower cable clamp 11, a clamping motor 13, a first gear mechanism, a first screw, a cutter 14, a cutter motor 12, a second gear mechanism, a second screw, and a control board. The clamping motor 13, cutter motor 12, and control board are fixed within the rotating housing, which is connected to the mounting base 4 via a linkage rod 3. The upper cable clamp 15 is coaxially arranged with the lower cable clamp 11 and is used to clamp the cable to be stripped; the clamping motor 13 is connected to one end of the first screw rod through a first gear mechanism, and the other end of the first screw rod is connected to the upper cable clamp 15 and the lower cable clamp 11; the upper cable clamp 15 is provided with a forward-rotating thread that cooperates with the first screw rod, and the lower cable clamp 11 is provided with a reverse-rotating thread that cooperates with the first screw rod; when the clamping motor 13 rotates forward, the clamping motor 13 drives the first screw rod to rotate forward, and the first screw rod drives the upper cable clamp 15 and the lower cable clamp 11 to close for clamping the cable; when the clamping motor 13 rotates reversely, the clamping motor 13 drives the first screw rod to rotate reversely, and the first screw rod drives the upper cable clamp 15 and the lower cable clamp 11 to separate for loosening the cable. The cutter motor 12 is connected to one end of a second screw rod via a second gear mechanism. The other end of the second screw rod is connected to a cutter 14. The cutter 14 is provided with a thread that mates with the second screw rod. When the cutter motor 12 rotates forward, the cutter motor 12 drives the second screw rod to rotate forward, which in turn drives the cutter 14 toward the cable, causing the cutter 14 to cut downward. When the cutter motor 12 rotates reversely, the cutter motor 12 drives the second screw rod to rotate reversely, which in turn drives the cutter 14 away from the cable, causing the cutter 14 to retract. In this embodiment of the present invention, a gear cover 17 is also provided for sealing the first and second gear mechanisms. A fixing plate 16 for mounting other components is provided inside the gear cover 17. The clamping motor 13 and the cutter motor 12 are electrically connected to a control board, which is provided with a communication circuit to enable communication between the control board and the control unit 6.

[0042] The electric cable stripper provided by the embodiment of the present invention is shown in FIG. Figure 2 To monitor the cable stripping process in real time, at least two metal probes 18 are provided. These probes are positioned behind the cutter 14 and connected to the lower cable clamp 11. Specifically, they are mounted on a slider that is mounted on the lower cable clamp 11 and can move up and down within the clamp. A spring is installed beneath the slider to ensure that the probes 18 maintain contact with the conductors. The lower ends of the probes 18 abut the outer sides of the cable. The control panel is equipped with ports that correspond to the probes 18 in a one-to-one manner. These ports are all combined input / output ports. Monitoring the cable stripping process requires the coordination of the software modules associated with the control unit 6.

[0043] In the embodiment of the present invention, see Figure 3 and Figure 5The control unit 6 includes a spindle motor 62, a mounting base, an indicator light and button assembly 61, a speed control button 64, and a controller 63. The spindle motor 62 is connected to the mounting base 4 via a power transmission rod 5, which is in turn connected to the rotating housing via a linkage rod 3. The spindle motor 62 is mounted within the mounting base. The indicator light and button assembly 61 is electrically connected to the controller 63; the speed control button 64 is electrically connected to the controller 63; and the controller 63 communicates wirelessly with the control panel.

[0044] Among them, see Figure 5 and Figure 6 The controller 63 includes software modules such as a potential management module, a potential detection module, a processing module, a motor control module, and a motion control module. Specifically:

[0045] The potential management module is used to apply a high potential or a low potential to the port.

[0046] The potential detection module is used to detect the potential of the port.

[0047] The processing module is used to select a port, control the potential management module to apply a high potential to the selected port, and control the potential detection module to detect the potential signals of other unselected ports; if at least one of the detected ports has a high level potential, a first determination signal is output to determine that the insulation layer of the wire is completely stripped, and a prompt message is issued.

[0048] The motor control module is used to receive the first trigger signal from the speed control button 64 and control the speed of the spindle motor 62 based on the first trigger signal. Specifically, the speed control button 64 changes the pressing distance as a control signal to the motor control module to control the speed of the spindle motor 62. A torque sensor is also installed on the spindle for status monitoring and protection.

[0049] The action control module is used to obtain the second trigger signal from the indicator light and button assembly 61 and control the rotating mechanism 1 to perform the cutting, wire breaking, or reset action based on the second trigger signal. Specifically, the indicator light and button assembly 61 includes four buttons and related indicator lights. The four buttons have the functions of cutting, wire breaking, resetting, and mode, respectively, and are all connected to the action control module to control the system operation. Resetting refers to the entire electric cable stripper returning to the initialization state, in which the cutter 14 retracts to the initial position and the upper and lower cable clamps retract to the maximum position. After returning to the reset state, the indicator light next to the reset turns off. After pressing the cutting button, the cutting indicator light turns on, and the action control module controls the spindle motor 62 to rotate. The spindle motor 62 drives the hanging base 4 to rotate through the power transmission rod 5, and the hanging base 4 drives the rotating mechanism 1 to rotate through the linkage rod 3. During this process, the upper and lower cable clamps automatically clamp the cable, and then the cutter 14 gradually cuts down. When it detects that the insulation layer has been completely cut through, the cutting stops, and the cutting indicator light turns off. After the cutter is in place and continues to cut the required length, click the wire cutting button, the cutter 14 will retreat a distance, continue to rotate the spindle motor 62 to cut the cable sheath, and finally click the reset button again to restore to the initial state. The key assembly is also provided with a mode button for function expansion.

[0051] The electric cable stripper provided in this embodiment of the present invention has a rotating mechanism connected to a mounting base via a linkage rod; the mounting base is connected to a control unit via a power transmission rod; a power supply unit is electrically connected to both the rotating mechanism and the control unit; and the control unit communicates wirelessly with the rotating mechanism. The electric cable stripper provided in this embodiment of the present invention utilizes a control unit to control actions such as clamping and cutting the cable within the stripper, adapting to cables of varying specifications.
