Description

Technical Field

[0001] This invention relates to the field of power construction equipment technology, specifically to a device for stripping the insulation sheath of low-voltage conductors. Background Technology

[0002] To ensure cable safety, primarily focusing on insulation safety, low-voltage conductors have a relatively stable overall structure. This adds difficulty for workers during the process of stripping the insulation from conductors. Therefore, wire strippers were developed to remove the insulation from conductors. Currently, most wire strippers on the market are designed for smaller diameter conductors and dominate the wire cutter market. For devices with motors designed for larger diameter conductors, it is often necessary to cut the conductor and strip the insulation from the cut surface at a predetermined depth. While this method effectively removes the insulation without damaging the conductor core, it compromises the integrity of the conductor and is not suitable for partial testing of the entire conductor on-site.

Those skilled in the art will understand that the invention can be practiced without certain specific details. In some instances, means well known to those skilled in the art have not been described in detail in order to highlight the spirit of the invention.

[0024] See Figure 1-4 The present invention provides a device for stripping the insulation of low-voltage conductors, comprising a first electric push rod 1, a second electric push rod 2, a third electric push rod 3, a first ring cutter 4, a second ring cutter 5, a cross cutter 6, and a clamping body 8.

[0025] The clamping body 8 has a clamping opening, and multiple rollers 9 are provided at the clamping opening position of the clamping body 8. The clamping body 8 is used to clamp the insulation sheath of the low-voltage wire under the operation of the operator.

[0026] The first electric push rod 1 is connected to the cross-cutting blade 6 and is used to push the cross-cutting blade 6 to a preset position to radially cut the insulation sheath of the low-voltage wire.

[0027] The second electric push rod 2 is connected to the first ring cutter 4 and is used to push the first ring cutter 4 to a preset position to assist in circumferentially cutting the insulation sheath of the low-voltage wire;

[0028] The third electric push rod 3 is connected to the second ring cutter 5 and is used to push the first ring cutter 4 to a preset position to assist in circumferentially cutting the insulation sheath of the low-voltage wire.

[0029] Furthermore, it also includes a roller lock 7, which is connected to the first electric push rod 1; wherein, the first electric push rod 1 is also used to push the roller lock 7 to press the roller 9.

[0030] Furthermore, the clamping body 8 includes a first clamping component and a second clamping component, the first clamping component and the second clamping component are connected by a wheel axle, and the first clamping component and the second clamping component can rotate around the wheel axle; the first end of the first clamping component and the first end of the second clamping component form the clamping opening, and the second end of the first clamping component and the second end of the second clamping component are used for clamping operation parts for use by the operator.

[0031] Furthermore, the second electric push rod 2 and the first ring cutter 4 are disposed on the outer side wall of the second clamping component, and the third electric push rod 3 and the second ring cutter 5 are disposed on the outer side wall of the first clamping component.

[0032] Furthermore, the transverse cutter 6 is disposed between the first annular cutter 4 and the second annular cutter 5.

[0033] Furthermore, the plurality of rollers 9 includes four rollers 9; wherein two rollers 9 are disposed on the first end of the first clamping member, and the other two rollers 9 are disposed on the first end of the second clamping member.

[0034] Furthermore, the roller lock 7, the cross-cutting blade 6, and the first electric push rod 1 are disposed on the first end of the first clamping component, and the roller lock 7 is specifically used to press the two rollers 9 disposed on the first end of the first clamping component.

[0035] The working principle of this invention is as follows:

[0036] The worker grips the clamping body 8 with both hands, using it in the same way as regular wire cutters. After opening the wire cutters and laying the wire flat, as... Figure 2 As shown, after clamping the wire with the first ring cutter 4 and rollers 9, both hands should be used to firmly clamp the clamping body 8, so that the wire and the wire cutters are relatively stationary in the radial direction. Figure 3As shown, at this time, the first ring cutter 4 and roller 9 can rotate freely, and the center of rotation coincides with the center of the clamped conductor cross-section. After clamping, the second electric push rod 2 and the third electric push rod 3 start to work. The stroke of the second electric push rod 2 and the third electric push rod 3 is specified according to the selected low-voltage conductor diameter. Under different conductor diameters, the insulation thickness of the low-voltage conductor is also different. By specifying the corresponding parameters, the stroke of the second electric push rod 2 and the third electric push rod 3 reaches a suitable value. The second electric push rod 2 and the third electric push rod 3 respectively carry... The first ring cutter 4 and the second ring cutter 5 cut into the insulation of the conductor, leaving a 1mm gap between them and the conductor core. This gap is achieved by setting the stroke value of the electric push rod to prevent damage to the conductor core during ring cutting. After the first ring cutter 4 and the second ring cutter 5 are in position, the worker still needs to hold the clamping body 8 by hand. Using the rolling of the roller 9, the clamping body 8 makes a circular motion around the center of the conductor cross-section, simultaneously driving the first ring cutter 4 and the second ring cutter 5 to cut through the insulation. After one rotation, two parallel cuts are made in the insulation. Figure 1 As shown, there is still a 1mm margin that has not been removed. At this time, the first electric push rod 1 is activated, which drives the roller lock 7 and the cross-cutting blade 6 to move downwards simultaneously via the connecting rod, each performing its own function. The downward movement of the roller lock 7 is used to lock the two rollers 9 of the first clamping part. After locking, the rollers 9 can no longer roll. The friction between the rollers 9 and the insulation sheath can be used to rotate the clamping body 8 while clamping it, so that it twists off the remaining 1mm margin of the insulation sheath. This method can ensure that the low-voltage conductor is not damaged. After the core is twisted off, a slit is cut at the corresponding positions of the first and second ring cutters (the two slits are parallel). However, the insulation sheath cannot be removed at this time. Therefore, the first electric push rod 1 continues to move down, driving the transverse cutter 6 to cut a slit in the transverse direction of the insulation sheath (located between the two slits cut earlier and perpendicular to the two slits cut earlier). After the three slits are cut, the low-voltage conductor insulation sheath stripping device can be removed, and then the insulation sheath can be completely removed.

[0037] As can be seen from the above description of the embodiments, the embodiments of the present invention do not require cutting the low-voltage conductor when stripping the insulation, and can effectively strip the insulation without damaging the conductor core, while ensuring the integrity of the low-voltage conductor, which is beneficial for use in the field when performing partial testing on the entire conductor.
