Description

Technical Field

[0001] This invention relates to the field of wire stripper technology, and more particularly to an intelligent wire stripper for live-line work. Background Technology

[0002] In the process of live-line work on general cable systems or power equipment systems, it is common to encounter situations where grounding rings or current-carrying rings need to be attached to the live lines, which requires live-line work such as stripping the insulation layer of the live lines.

[0003] Currently, the existing live-line working process typically involves workers using manual wire strippers to clamp the conductor, wrap it around the conductor, and then manually and slowly push the blades forward to peel off the insulation layer by layer. While this method meets basic operational needs, it is inefficient, time-consuming, and labor-intensive. Furthermore, due to the uneven thickness of the insulation layer across the same cross-section, the operation is difficult to control and precise, and the conductor is easily damaged in practice. Summary of the Invention

[0004] In view of the technical problems existing in the prior art, the purpose of this invention is to provide an intelligent wire stripper for live-line work, so as to solve the problems that existing live-line work workers use manual wire strippers to clamp the wire and wrap it around the wire, which is inefficient, time-consuming and laborious, and easy to damage the wire in actual operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent wire stripper for live-line work, comprising a support rod, an extension rod, and a U-shaped frame.

A fixed frame is connected to the front end of the extension rod, and the fixed frame is connected to the U-shaped frame. A pulling mechanism is provided inside the U-shaped frame, and two pressure rods are connected to the pulling mechanism. The pressure rods are slidably connected to the U-shaped frame, and stripping blades are connected to the pressure rods. The blades of the two stripping blades face each other and are arc-shaped. The pulling mechanism drives the two stripping blades to move closer or further apart through the pressure rods. The cable to be stripped is located between the two stripping blades. Pushing mechanisms are provided on both sides of the stripping blades. The pushing mechanism includes a connecting rod, an inclined rod, and an arc-shaped pad. The connecting rod is connected to the pressure rod and slides with the pressure rod. The two ends of the inclined rod are rotatably connected to the connecting rod and the arc-shaped pad, and the position of the arc-shaped pad corresponds to the position of the cable.

[0006] As a preferred embodiment, the front end of the support rod has an extension groove, the extension rod is slidably installed in the extension groove, the electric propulsion mechanism is installed in the extension groove, the fixed frame is equipped with a rotating mechanism, and arc-shaped blocks are fixedly installed on the inner walls of both sides of the fixed frame. The same arc-shaped plate is slidably installed on the two arc-shaped blocks. Arc-shaped grooves are opened on both sides of the arc-shaped plate, and the arc-shaped blocks are slidably connected to the inner walls of the arc-shaped grooves. The rotating mechanism is connected to the arc-shaped plate, the U-shaped frame is located inside the arc-shaped plate, and stabilizing rods are fixedly installed at both ends of the arc-shaped plate. The two stabilizing rods are fixedly connected to the U-shaped frame. The U-shaped frame is equipped with a cavity, and the pulling mechanism is set in the cavity. Two sliding holes are opened on the inner wall of the cavity, and the pressure rod is slidably connected to the inner wall of the sliding hole. Receiving grooves are opened on both sides of the inner wall of the U-shaped frame, and two peeling knives are slidably connected to the inner walls of the two receiving grooves respectively.

[0007] As a preferred embodiment, the electric propulsion mechanism includes a servo motor, which is mounted on the inner wall of the extension groove. A lead screw is fixedly mounted on the output shaft of the servo motor, and a lead screw groove is provided on the extension rod. The lead screw is threadedly connected to the lead screw groove.

[0008] As a preferred embodiment, two balls are embedded in the outer side of the extension rod, and two ball grooves are symmetrically arranged on the inner wall of the extension groove, with the balls slidingly connected to the inner wall of the ball grooves.

[0009] As a preferred embodiment, the rotating mechanism includes a mounting rod mounted on a fixed frame, a stepper motor mounted on the mounting rod, a transmission wheel mounted on the output shaft of the stepper motor, and the transmission wheel being connected to the outer side of the arc-shaped plate.

[0010] As a preferred embodiment, a recess is provided on the inner wall of the cavity, a transparent mirror is embedded in the recess, a welding shell is provided on the outside of the recess, a camera is provided on the welding shell, the camera is adapted to the transparent mirror, and the camera faces the cable.

[0011] As a preferred embodiment, the approaching mechanism includes a worm motor mounted on the outside of the welded shell, with a worm installed at the outer end of the worm motor. A bidirectional screw is rotatably mounted on the inner wall of the cavity, with a worm wheel sleeved at the center of the bidirectional screw. The worm and the worm wheel mesh with each other. The bidirectional screw includes two threaded segments with opposite thread directions, and two pressure rods are threadedly connected to the two threaded segments respectively.

[0012] As a preferred embodiment, guide rods are fixedly installed on both sides of the welded shell, and two pressure rods are slidably installed on the outside of the two guide rods.

[0013] As a preferred embodiment, notches are provided on both sides of the inner wall of the receiving groove, the connecting rod is slidably connected to the inner wall of the corresponding notch, two arc-shaped holes are provided on the outer side of the inclined rod, and arc-shaped rods are fixedly installed on the connecting rod and the arc-shaped pad respectively. The two arc-shaped rods are slidably connected to the inner wall of the two arc-shaped holes respectively, and stabilizing springs are sleeved on the outer side of the two arc-shaped rods.

[0014] As a preferred embodiment, a power source is provided on the outside of the support rod, a switch is provided on the power source, and a handle is installed at the end of the support rod.

[0015] The present invention has the following advantages:

[0016] This solution places the cable between two stripping blades. If the extension length is insufficient, a servo motor drives a lead screw to rotate. The lead screw pushes an extension rod through a lead screw groove, which in turn pushes a fixed frame to move. The fixed frame then moves a U-shaped frame and the two stripping blades, allowing for adjustment of the extension length to meet different usage requirements.

[0017] When cable stripping is required, this solution uses a worm motor to drive a bidirectional screw to rotate via a worm and worm wheel. The bidirectional screw drives two pressure rods to move closer together. A camera monitors the cable, allowing for the assessment of its dimensions. The pressure rods move the stripping blades to contact the cable, and the two blades cut the cable sheath. By assessing the cable's dimensions and further analyzing the sheath thickness, the cutting depth of the stripping blades is determined to be less than the cable sheath's dimensions. During the cutting process, the pressure rods push an arc-shaped pad through two inclined rods. The arc-shaped pads compress the cable sheath, causing the inclined rods to tilt and pull the cable along the cutting position to both sides, facilitating stripping. This solution enables automatic cutting and stripping, while simultaneously pulling the cable during the cutting process.

[0018] To facilitate placing the cable between the two stripping blades, this solution requires adjusting the angles of the U-shaped frame and the two stripping blades. Starting the stepper motor drives the transmission wheel to rotate, which in turn adjusts the angle of the arc-shaped plate. The arc-shaped plate is supported by the arc-shaped groove, thus achieving the purpose of adjusting the angles of the U-shaped frame and the two stripping blades, making operation convenient.

[0019] In summary, this invention allows for adjustable length, automatic cutting and stripping, and simultaneous pulling during the cutting process. It also allows for adjustment of the angles of the U-shaped frame and the two stripping blades, making it convenient for cutting and stripping cables. Attached Figure Description

[0038] Notches 34 are provided on both sides of the inner wall of the receiving groove 28. The connecting rod 36 is slidably connected to the inner wall of the corresponding notch 34.

[0039] A power supply 3 is installed on the outside of the support rod 1, and a switch is installed on the power supply 3. A handle 2 is installed at the end of the support rod 1.

[0040] When using the above-mentioned intelligent wire stripper for live-line work, an external power supply 33 and a switch are connected. The handle 22 makes it easy to carry the whole device.

The pressure rods 27 drive stripping blades 29 to move and contact cable 30. The two stripping blades 29 cut the outer sheath of cable 30. After determining the size of cable 30, the thickness of the outer sheath is further analyzed to ensure that the cutting depth of the stripping blades 29 is less than the size of the outer sheath of cable 30. During the cutting process, the pressure rods 27 push the arc-shaped pad 35 to move via two inclined rods 37. The arc-shaped pad 35 squeezes the outer sheath of cable 30, and the inclined rods 37 tilt, which can pull cable 30 to both sides along the cutting position to facilitate stripping. Automatic cutting and stripping can be achieved, and the cable 30 is pulled during the cutting process.

[0042] To facilitate placing the cable 30 between the two stripping blades 29, the angles of the U-shaped frame 19 and the two stripping blades 29 need to be adjusted. The stepper motor 13 is started, and the stepper motor 13 drives the transmission wheel 14 to rotate. The transmission wheel 14 drives the arc plate 15 to adjust its angle. The arc plate 15 is supported by the arc groove 17, thereby achieving the purpose of adjusting the angles of the U-shaped frame 19 and the two stripping blades 29, which facilitates the cutting and stripping of the cable 30.
