Abstract
Description
Technical Field
[0001] This invention belongs to the field of electrical maintenance equipment technology, and more specifically, relates to a mechanical wire stripper. Background Technology
[0002] To improve the safety of overhead power distribution lines, cross-linked polyethylene (XLPE) insulated conductors are now widely used in power systems. When performing live-line work on distribution lines, it is often necessary to strip the insulation of the conductors before installing clamps and leads to complete the connection. Therefore, for the safety of workers, when performing live-line work, workers typically need to use an overhead conductor stripper to remove the outer insulation of the conductors.
[0003] Currently, the products on the market use a rotary cutting stripping technology. This involves inserting a blade into the insulation layer of the wire and then moving it spirally along the wire's axis, cutting the insulation layer into a spring-like shape. After cutting to a certain length, the blade moves in a circular motion via a limiting block, thus severing the spring-like insulation layer. The insulation is then manually peeled off, completing the wire stripping operation. However, in confined spaces or at heights, manually peeling the insulation not only requires excessive movement from the operator, increasing the risk of danger, but also, in low winter temperatures, the hardening of the insulation further complicates the process, making manual stripping even more difficult. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

In the claims, description, and accompanying drawings of this invention, the terms "comprising," "having," and their variations are intended to mean "including but not limited to."
[0049] Please refer to the following: Figure 1 and Figure 2The mechanical wire stripper provided by the present invention will now be described. The mechanical wire stripper includes a handle 1, a cutting unit 2 connected to one end of the handle 1, and a separating unit 3 connected to the cutting unit 2 along a first path, the first path being perpendicular to the long axis of the handle 1;
[0050] The cutting unit 2 includes a housing 203 with an internal cavity, and a cutting component and a rotating component 202 disposed within the cavity. The housing 203 is connected to one end of the handle 1. The housing 203 has a circular receiving hole 2031 at its center. The axis of the receiving hole 2031 is parallel to the first path. The housing 203 also has an annular opening that connects the cavity and the receiving hole 2031. The cutting component is rotatably connected to the housing 203. The cutting component includes a cutting part that extends from the annular opening into the receiving hole 2031. The rotating component 202 is rotatably disposed within the cavity and connected to the cutting component. The rotating component 202 is used to drive the cutting part to cut the insulation layer along the circumference of the wire.
[0051] Separation unit 3 is used to cut the insulation layer along the axial direction of the conductor and separate the insulation layer from the conductor core.
[0052] Compared with existing technologies, the mechanical wire stripper provided by this invention allows the operator to hold the handle 1 and pass the wire through the receiving hole 2031. The rotating component 202 drives the cutting part to rotate around the circumference of the wire, cutting the insulation layer along the guide circumference. Then, the device is moved along the circumference of the wire, and after a certain distance, the insulation layer is cut circumferentially at another point on the wire in the same manner. Finally, the separation unit 3 cuts the insulation layer between the two cut points axially, and can also separate the cut insulation layer from the wire core. This device eliminates the need for the operator to rotate the handle 1 to drive the cutting unit 2, reducing the operator's range of motion and ensuring operator safety when working at heights or in confined spaces. Furthermore, the separation unit 3 can peel off the cut insulation layer without manually separating it from the wire core, reducing the risk of electric shock. Even in low-temperature environments, the hardened insulation layer can be easily cut and separated, reducing the difficulty of wire stripping.
[0053] It should be noted that a conductor consists of a core and an insulation layer that wraps around the core. When stripping the wire, the insulation layer needs to be cut and separated to expose the core.
[0054] In some embodiments, please refer to Figures 1 to 2The cutting assembly includes a first toothed disc 2013, a first gear 2011, a cutter 2012, and a drive mechanism 204. The first toothed disc 2013 is disposed in a cavity, and the inner edge of the first toothed disc 2013 has connecting teeth. The first gear 2011 meshes with the first toothed disc 2013. The cutter 2012 is connected to the first gear 2011 and forms a cutting part. The drive mechanism 204 is connected to the first toothed disc 2013 and is used to drive the first toothed disc 2013 to rotate. As the gear rotates, the cutter 2012 has a cutting state that is radially distributed along the first toothed disc 2013 and a retracted state that is circumferentially distributed along the first toothed disc 2013.
[0055] The drive mechanism 204 controls the rotation of the first gear disk 2013, and the first gear 2011 meshing with the first gear disk 2013 rotates synchronously. During the rotation of the first gear 2011 around its own axis, the cutter 2012 connected to the first gear 2011 rotates, causing the cutter 2012 to contact the insulation layer. As the gear rotates further, the cutter 2012 cuts the insulation layer. After cutting, the drive mechanism 204 controls the rotation of the first gear disk 2013, and under the action of the first gear 2011, the cutter 2012 switches from the cutting state to the retracted state. In this embodiment, during the process of the wire entering the receiving hole 2031, the cutter 2012 remains in the retracted state to avoid affecting the wire's entry into the receiving hole 2031. After the wire enters the receiving hole 2031, the handle 1 is moved until the cutter 2012 corresponds to the designated position of the insulation layer. Then, the drive mechanism 204 is activated, switching the cutter 2012 from the retracted state to the cutting state to cut the surface of the insulation layer. At the same time, the rotating component 202 controls the cutter 2012 to rotate around the axis of the insulating layer to cut it.
[0056] Optionally, as a specific implementation of the drive mechanism 204 in this embodiment, the outer edge of the first gear disk 2013 has rotating teeth, and the drive mechanism 204 includes a drive gear meshing with the rotating teeth and a motor coaxially connected to the drive gear. The motor controls the drive gear to rotate, thereby causing the first gear disk 2013 to rotate.
[0057] In some embodiments, please refer to Figures 1 to 2 The first gear 2011 is provided in multiple ways. The multiple first gears 2011 are symmetrically arranged around the axis of the first gear disk 2013, and each first gear 2011 meshes with the first gear disk 2013. Each first gear 2011 is connected to a cutter 2012.
[0058] The solution in this embodiment can enable multiple cutters 2012 to cut the insulation layer simultaneously. The multiple cutters 2012 cut into the circumference of the insulation layer respectively. Then, the rotating component 202 controls the first gear 2011 and the cutters 2012 to rotate, connecting the multiple cuts to form a ring cut, reducing the rotation angle of the first gear 2013 and improving the cutting efficiency.
[0059] Optionally, the cutter 2012 is an arc-shaped blade. When multiple cutters 2012 are in the cutting state, they surround the center to form a ring-shaped cutting space, and the wire is located within the cutting space.
[0060] In some embodiments, please refer to Figure 1 and Figure 3 The drive mechanism 204 includes a first driver 2043, an eccentric drive shaft 2042, and a connector 2041. The first driver 2043 is disposed in the cavity and connected to the housing 203. One end of the eccentric drive shaft 2042 is connected to the drive end of the first driver 2043, and the other end is eccentrically connected to a rotating shaft. The connector 2041 is connected to the first gear disk 2013, and the rotating shaft is rotatably connected to the connector 2041.
[0061] The first driver 2043 controls the eccentric drive shaft 2042 to rotate eccentrically. When the eccentric drive shaft 2042 rotates eccentrically, the connecting piece 2041 oscillates, causing the first gear disk 2013 to reciprocate around its own axis. In this embodiment, the first gear disk 2013 does not need to rotate a full revolution. During the small-range rotation of the first gear disk 2013, the cutter 2012 switches between cutting and storage states, making operation more convenient and improving cutting efficiency.
[0062] Optionally, the first driver 2043 is a motor.
[0063] In some embodiments, please refer to Figures 1 to 2 The rotating assembly 202 includes a second gear disk 2021, a second gear 2022, and a second driver. The second gear disk 2021 is coaxially arranged with the first gear disk 2013 and is located on one side of the first gear disk 2013 on a first path. The outer periphery of the second gear disk 2021 has driving teeth. The first gear 2011 is rotatably connected to the second gear disk 2021 around its own axis. The second gear 2022 meshes with the second gear disk 2021. The second driver is connected to the second gear 2022 and is used to control the second gear 2022 to rotate around its own axis.
[0064] The second driver controls the rotation of the second gear 2022, and the second gear disk 2021, which meshes with the second gear 2022, rotates around its own axis. This causes the first gear 2011 connected to the second gear disk 2021 to rotate synchronously (the first gear 2011 rotates around the axis of the second gear disk 2021), thereby rotating the cutter 2012. During rotation, the cutter 2012 cuts the circumference of the insulating layer, forming an annular cut. In this embodiment, the second drive and the second gear 2022 control the selection of the second gear disk 2021, thereby enabling the cutter 2012 to form an annular cut on the insulating layer. This eliminates the need for manual rotation of the handle 1, reducing the operator's range of motion and allowing for one-handed operation.
[0065] Optionally, the second drive is a motor or a hand crank, preferably a motor.
[0066] In one specific embodiment of the cutting assembly 201, both the first toothed disc 2013 and the second toothed disc 2021 have radially formed wire inlet slots, and the housing 203 has a wire inlet corresponding to the wire inlet slot. The wire can be guided from the wire inlet and the wire inlet slot into the receiving hole 2031. During wire feeding, the position of the second toothed disc 2021 is adjusted by the drive mechanism 204 so that the groove of the second toothed disc 2021 corresponds to the groove of the first toothed disc 2013, facilitating the entry of the wire into the receiving hole 2031.
[0067] In some embodiments, please refer to Figure 4 The separation unit 3 includes a housing 303, an adjustment component, and a separation component. The housing 303 is connected to the housing 203 along a first path. A clearance hole 3031 corresponding to the receiving hole 2031 is opened at the center of the housing 303 along the first path. The clearance hole 3031 communicates with the interior of the housing 303. The adjustment component is located inside the housing 303. The adjustment component includes a first adjustment mechanism 301 and a second adjustment mechanism 302 connected to the first adjustment mechanism 301. The first adjustment mechanism 301 controls the second adjustment mechanism 302 to move up and down. The second adjustment mechanism 302 can move along a second path, which is perpendicular to the first path. The separation component includes two separation blades 304 arranged along the second path. The separation blades 304 are located in the clearance hole 3031. Both separation blades 304 are connected to the second adjustment mechanism 302.
[0068] The conductor enters the receiving hole 2031 and the clearance hole 3031. The second adjusting mechanism 302 brings the two separating blades 304 together on the second path. The first adjusting mechanism 301 controls the separating blades 304 to contact the insulation layer of the conductor and gradually cut into it. Then, the operator moves the handle 1 along the axial direction of the conductor, forming a cut on the insulation layer along the axial direction. This straight cut connects the two annular cuts previously formed by the cutting part. Keeping the separating blades 304 within the straight cut, the second adjusting mechanism 302 controls the two separating blades 304 to move away from each other on the second path, increasing the size of the straight cut until the insulation layer separates from the conductor core, thus achieving insulation stripping. In this embodiment, the solution eliminates the need for manual peeling of the insulation from the cut, reducing the operational range. Even when the insulation has hardened, the separation of the insulation from the conductor core can be easily achieved.
[0069] In some embodiments, please refer to Figure 4 The first adjustment mechanism 301 includes a third driver 3011, a first lead screw 3013, a first guide rod 3014, and a connecting seat 3012. The third driver 3011 is located inside the housing 303. The first lead screw 3013 is located inside the housing 303 in a vertical direction. One end of the first lead screw 3013 is connected to the third driver 3011, and the other end is connected to the housing 303 through a first bearing 3015. The first guide rod 3014 is located inside the housing 303 parallel to the first lead screw 3013. The connecting seat 3012 is threaded to the two first lead screws 3013. The second adjustment mechanism 302 is connected to the first guide rod 3014.
[0070] The third actuator 3011 controls the rotation of the first lead screw 3013. Under the action of the first guide rod 3014, the connecting seat 3012 moves along the axis of the first lead screw 3013 (vertically), causing the second adjusting mechanism 302 to move closer to or further away from the wire. During cutting, the third actuator 3011 controls the connecting seat 3012 to move the second adjusting mechanism 302 downwards until the separating blade 304 contacts the insulation layer, forming a cut on the surface of the insulation layer. Then, the handle 1 is moved axially along the insulation layer, forming a straight cut on the insulation layer, thereby connecting the two annular cuts formed by the cutting part, facilitating the separation of the insulation layer. In this embodiment, the solution eliminates the need for manual force application to the separating blade 304 on the insulation layer. Even if the insulation layer surface hardens, cutting can be easily achieved, avoiding the difficulty in controlling manual force, which could lead to incomplete cutting or excessive force cutting off the wire core.
[0071] Optionally, the third drive 3011 is a motor.
[0072] In some embodiments, please refer to Figure 4The first lead screw 3013 has two first threaded parts along its own axis, and the two first threaded parts have opposite thread directions. There are two connecting seats 3012, and each connecting seat 3012 is connected to one first threaded part. There are two sets of second adjustment mechanisms 302, and each set of second adjustment mechanisms 302 is connected to one connecting seat 3012.
[0073] Under the action of the third actuator 3011, the two connecting seats 3012 move in opposite directions axially to the first lead screw 3013. When cutting the insulation layer, the third actuator 3011 controls the two connecting seats 3012 to move closer together, causing the separating blades 304 on the two sets of second adjusting mechanisms 302 to simultaneously cut the insulation layer in the vertical direction. In this embodiment, the insulation layer is cut simultaneously vertically, creating two symmetrical straight cuts on the insulation layer. When separating the insulation layer, it peels off along the two symmetrical straight cuts, making separation easier.
[0074] In some embodiments, please refer to Figure 4 The second adjustment mechanism 302 includes a slide rail 3021, a fourth driver 3026, a second lead screw 3023, a second guide rod 3024, and two mounting seats 3022. The slide rail 3021 is located inside the housing 303 in the vertical direction and is parallel to the first guide rod 3014. The fourth driver 3026 is slidably connected to the slide rail 3021. One end of the second lead screw 3023 is connected to the fourth driver 3026, and the other end is rotatably connected to the connecting seat 3012. The second lead screw 3023 has two sets of second threaded portions with opposite screw directions along its own axial direction. The second guide rod 3024 is parallel to the second lead screw 3023. One end of the second guide rod 3024 is connected to the connecting seat 3012, and the other end is connected to the slide rail 3021 through a second bearing 3025. Each mounting seat 3022 is threaded to one of the second threaded portions, and each separating blade 304 is connected to one mounting seat 3022.
[0075] After a straight cut is formed on the surface of the insulation layer, the fourth actuator 3026 controls the two mounting bases 3022 to move away from each other, thereby causing the two separating blades 304 to move away from each other, separating until the cut is widened along the second path, separating the insulation layer from the wire core, and realizing the peeling off of the insulation layer.
[0076] In some embodiments, please refer to Figure 4 The second adjustment mechanism 302 also includes a proximity switch sensor connected to the mounting base 3022. The proximity switch sensor and the third driver 3011 are respectively connected to the controller.
[0077] The proximity switch sensor can detect the distance between the mounting base 3022 and the insulation layer, and control the cutting depth of the separating blade 304. Since the thickness of the insulation layer of the wire can be known in advance according to its model, a predetermined value can be set on the proximity switch sensor. When the proximity switch sensor detects that the distance between the mounting base 3022 and the insulation layer reaches the preset value, a stop signal is generated. The controller controls the third driver 3011 to stop working according to the stop signal, thereby controlling the feed amount of the separating blade 304.
[0078] It should be noted that the distance between the cutting part of the separating blade 304 and the proximity switch sensor is constant. The depth of the cutting part penetrating the insulation layer can be determined based on the distance between the proximity switch sensor and the surface of the insulation layer.
[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The separation unit is used to cut the insulation layer along the axial direction of the conductor and separate the insulation layer from the conductor core; The separation unit includes: The housing is connected to the shell along the first path, and a clearance hole corresponding to the receiving hole is opened at the center of the housing along the first path, and the clearance hole communicates with the interior of the housing. An adjustment assembly is disposed within the housing. The adjustment assembly includes a first adjustment mechanism and a second adjustment mechanism connected to the first adjustment mechanism. The first adjustment mechanism controls the second adjustment mechanism to move up and down. The second adjustment mechanism can move along a second path, which is perpendicular to the first path. as well as The separation assembly includes two separation blades disposed along the second path, the separation blades being located within the clearance hole, and both separation blades being connected to the second adjustment mechanism; The conductor enters the receiving hole and the clearance hole. The second adjustment mechanism makes the two separating blades fit together on the second path. The first adjustment mechanism controls the separating blades to contact the insulation layer of the conductor and gradually cut into the insulation layer. Then, the operator holds the handle and moves it along the axial direction of the conductor, forming a straight cut on the insulation layer along the axial direction. This straight cut connects the two annular cuts previously formed by the cutting part. Keeping the separating blades in the straight cut, the second adjustment mechanism controls the two separating blades to move away from each other on the second path, making the straight cut larger until the insulation layer separates from the conductor core, thus achieving the stripping of the insulation layer.
