Description

Technical Field

[0001] This invention relates to the field of switchgear wiring, and more specifically, to an automatic installation device for wiring high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear, as the name suggests, is equipment that connects high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage switchgear, which is then stepped down by transformers to low-voltage switchgear, and then to various power distribution boxes. Inside, there are simply electrical devices that assemble some protective devices such as switches and circuit breakers into one unit. Cables need to be installed inside the high and low voltage switchgear to transmit electrical energy and signals.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] See Figures 1 to 12As shown, an automatic wiring installation device for high and low voltage switchgear includes a vertical plate 1, a stripping mechanism 2, and an end mounting mechanism 3. Triangular movable seats 11 are provided at both ends of the bottom of the vertical plate 1 along its length. A horizontal plate 12 is provided at the center of one side of the vertical plate 1. Multiple connecting strips 121 are equidistantly arranged on the horizontal plate 12 along its length. Each connecting strip 121 has an annular guide rail 13 at its end. The annular guide rail 13 is horizontally positioned and has a first arc-shaped notch 131 for cable passage. Each annular guide rail 13 contains... A sliding ring slider 14 is provided, and each ring slider 14 is provided with a second arc-shaped notch 141 corresponding to the first arc-shaped notch 131. Two first hydraulic rods 142 are mirror-arranged on the bottom of each ring slider 14. The driving direction of the two first hydraulic rods 142 is towards the center of the corresponding ring slider 14. A vertical bar 15 is also provided at the driving end of each first hydraulic rod 142. Two locking blocks 16 are mirror-arranged on each vertical bar 15. The two locking blocks 16 are V-shaped. Each locking block 16 is provided with a... A rectangular groove 161 is provided; there are multiple sets of circumferential stripping mechanisms 2, which are set in the corresponding rectangular grooves 161 and used to cut the insulation layer of the cable; each set of circumferential stripping mechanisms 2 includes a mounting plate 21, a first cutter 22, a second cutter 23 and a linkage assembly 24; the mounting plate 21 is set at the opening of the corresponding rectangular groove 161, and a strip-shaped through groove 211 is provided on the mounting plate 21, in which the first cutter 22 is slidably arranged; the mounting plate 21 is also provided with a rectangular through groove 212, in which the second cutter 23 is slidably arranged. 3. The first cutter 22 can move along a direction perpendicular to the mounting plate 21, and the second cutter 23 can move along a vertical direction. The first cutter 22 and the second cutter 23 are parallel to each other and their moving directions are perpendicular to each other. The linkage component 24 is set in the corresponding rectangular groove 161 and can move the corresponding first cutter 22 synchronously with the movement of the second cutter 23. There are multiple end mounting mechanisms 3. The end mounting mechanisms 3 are set on the corresponding annular guide rail 13 and are used to fit the copper lug onto the end of the cable and press and fix it.

[0023] The operator places the corresponding number of cables at the center of the corresponding annular slider 14 through the first arc-shaped notch 131 and the second arc-shaped notch 141, and moves the ends upwards to the required stripping length for the copper lug. Then, by adjusting the two first hydraulic rods 142 on the corresponding annular slider 14, the vertical bars 15 at the ends of the two first hydraulic rods 142 are brought closer together. At this time, the two locking blocks on the vertical bars 15 can contact the outer wall of the corresponding cable, and the first cutter 22 and the second cutter 23 on the mounting plate 21 can contact the insulation layer of the cable's outer wall, thereby adjusting the position of cables of different specifications to ensure the cable is coaxially aligned with the corresponding annular slider 14. Subsequently, the annular slider 14 rotates along the annular guide rail 13, allowing the first cutter 22 and the second cutter 23 to perform annular cuts on the cable, dividing the insulation layer at the cable end into two parts. Then, the operator pulls the cable to move it vertically downwards. During this movement, the second cutter 23 contacts the cut insulation sleeve, allowing the second cutter 23 to cut along a rectangular path in the vertical direction. The slot 212 moves, pushing the cut insulation layer toward the cable end. During the movement, the linkage component 24 causes the corresponding first cutter 22 to retract into the corresponding rectangular groove 161 through the strip groove 211, thus preventing the first cutter 22 from affecting the installation process of the copper lugs. At this time, the insulation layer between the first cutter 22 and the second cutter 23 can adjust the wire bundle inside the cable during the movement, so that the internal wire bundle fits precisely and is not scattered. The insulation layer at the end falls off from the cable end as the cable moves. Then, the end mounting mechanism 3 allows the corresponding number of copper lugs to be fitted onto the corresponding cable end and pushes the insulation layer between the first cutter 22 and the second cutter 23 to move, so that the cable at the end that is not covered by the insulation layer can move into the copper lug. Then, the end mounting mechanism 3 squeezes the copper lug to fix it. Then, the operator takes out the cable through the first arc notch 131 and the second arc notch 141 and installs it with the switch in the cabinet, thus completing the entire installation work.

[0024] See Figures 11 to 12As shown, the linkage component 24 includes a positioning plate 241; the positioning plate 241 is located at the center of one end of the corresponding second cutter 23 that extends into the corresponding rectangular groove 161, the positioning plate 241 and the second cutter 23 are perpendicular to each other, a right-angled trapezoidal block 242 is provided on the top of the positioning plate 241, and a strip-shaped clearance groove 221 for accommodating the positioning plate 241 is provided on the side of the positioning plate 241 near the corresponding mounting plate 21, and an abutment plate 243 for abutting against the inner wall of the corresponding strip-shaped clearance groove 221 is also provided; a plurality of first return springs 222 are provided at one end of the first cutter 22 that extends into the rectangular groove 161, and a plurality of second return springs 231 are provided on the side of the second cutter 23 away from the first cutter 22.

[0025] When the first cutter 22 and the second cutter 23 cut the cable, the abutment plate 243 on the locking plate 241 can abut against the inner wall of the strip-shaped clearance groove 221 on the first cutter 22, and the second cutter 23 can only move in the vertical direction, thereby preventing the first cutter 22 and the second cutter 23 from shaking when cutting the cable and ensuring the cutting quality; after the cutting is completed, as the cable moves, the second cutter 23 contacts the cut insulation layer, thereby enabling the second cutter 23 to overcome the elastic force of the second return spring 231 and move, and the abutment plate As the second cutter 23 moves, the 243 can separate from the strip-shaped clearance groove 221. Subsequently, the inclined surface of the right-angled trapezoidal block 242 can contact the strip-shaped clearance groove 221, thereby allowing the first cutter 22 to overcome the elastic force of the first return spring 222 and retract into the rectangular groove 161, preventing the first cutter 22 from affecting the installation of the copper lug. At this time, the second cutter 23 can push out the insulation layer at the end of the cable. The insulation layer located at the positions of the first cutter 22 and the second cutter 23 can concentrate the internal wire bundle of the cable, thereby ensuring that the copper lug can be installed smoothly.

[0026] See Figure 1 , Figures 6 to 8 As shown, each set of end mounting mechanisms 3 includes a C-shaped plate 31 and a second hydraulic rod 32. The two ends of the C-shaped plate 31 are respectively set at the edges of the corresponding annular guide rail 13. The second hydraulic rod 32 is set vertically at the top of the C-shaped plate 31. The actuator of the second hydraulic rod 32 passes through the C-shaped plate 31 and is provided with a lower pressure plate 321. The outer walls on both sides of the C-shaped plate 31 are also provided with a third hydraulic rod 311. The actuator of each third hydraulic rod 311 passes through the C-shaped plate 31 and is provided with a vertical guide rail 312. A sliding block 313 is slidably arranged in each vertical guide rail 312. A third return spring 314 is also provided at the bottom of each sliding block 313. A V-shaped plate 315 for positioning the copper nose is provided on the opposite side of the two sliding blocks 313.

[0027] The worker places the copper lug between two V-shaped plates 315. Then, the copper lug is centered and fixed by the V-shaped plates 315 on both sides of the V-shaped plate 31. After the cable is cut, the lower pressure plate 321 is driven by the second hydraulic rod 32 to move the copper lug toward the end of the cable. At this time, the two sliding blocks 313 can move accordingly to overcome the elastic force of the third return spring 314 as the copper lug moves, thereby ensuring the accuracy of the copper lug's position during installation. After the lug is fitted, the second hydraulic rod 32 continues to press, causing the copper lug to deform and connect with the stripped end of the cable, thereby ensuring the connection strength.

[0028] See Figures 9 to 12 As shown, each vertical bar 15 is also equipped with a longitudinal cutting mechanism 4 for secondary cutting of the cable insulation layer; each longitudinal cutting mechanism 4 includes a moving plate 41 and a triangular cutter 42; a vertical through groove 151 is provided at the center of each vertical bar 15, and the moving plate 41 is slidably disposed in the vertical through groove 151; a traction rope 232 is also provided on the side of each second cutter 23 near the vertical through groove 151; two traction holes 152 are provided on the vertical bar 15 for the traction rope 232 to pass through, and the traction rope 232 passes through the corresponding traction hole 152 and is disposed on the corresponding side of the moving plate 41 away from the center of the annular guide rail 13; a fourth return spring 233 is also sleeved on each traction rope 232, and the fourth return spring 233 is located on the side of the vertical bar 15 away from the center of the annular guide rail 13; a triangular cutter 42 is provided on the side of each moving plate 41 near the center of the annular guide rail 13.

[0029] To further ensure cable safety, after the copper lug is installed, the annular insulation layer located between the first cutter 22 and the second cutter 23 during cable cutting needs to be removed. A triangular cutter 42 is provided; when the second cutter 23 is pushed, it pulls the moving plate 41 via the traction rope 232, allowing the moving plate 41 to overcome the elastic force of the fourth return spring 233 and move towards the cable. The triangular cutter 42 at the end of the moving plate 41 can then be inserted below the annular insulation layer. Subsequently, the operator uses the second hydraulic rod 32 to move the copper lug towards the cable end, bringing it into contact with the annular insulation layer. This pushes the annular insulation layer into contact with the triangular cutter 42, allowing the triangular cutter 42 to cut and remove the annular insulation layer. After the copper lug has been pressed in a certain distance, the two first hydraulic rods 142 separate, allowing the cable to continue into the copper lug for an appropriate length. Then, under the pressure of the two V-shaped plates 315, the copper lug is fixed, ensuring the connection strength between the cable and the copper lug.

[0030] See Figures 7 to 8As shown, each annular slider 14 has multiple gear teeth 143 circumferentially arranged on its outer wall. The horizontal plate 12 has multiple extension plates 122 along its length. Each extension plate 122 has a rotating hole 1221 at its end away from the horizontal plate 12. A connecting shaft 123 is rotatably arranged within each rotating hole 1221. A synchronous gear 1231 is coaxially arranged at the lower end of each connecting shaft 123, and the synchronous gear 1231 meshes with the gear teeth 143 on the adjacent annular slider 14. A driven wheel is arranged at the upper end of each connecting shaft 123. 1232, Multiple drive wheels 124 are equidistantly arranged on the horizontal plate 12. The drive wheels 124 are connected to the synchronous pulleys via a synchronous belt 125. Each drive wheel 124 is coaxially provided with a first bevel gear 1241. Rotating plates 126 are provided at both ends of the horizontal plate 12 along its length. A synchronous shaft 127 is rotatably arranged between the two rotating plates 126. Multiple second bevel gears 1271 are equidistantly arranged along the length of the synchronous shaft 127. The second bevel gears 1271 mesh with the corresponding first bevel gears 1241.

[0031] One of the rotating plates 126 is equipped with a drive motor for driving the synchronous shaft 127 to rotate. The drive motor drives the synchronous shaft 127 to rotate. As the synchronous shaft 127 rotates, multiple second bevel gears 1271 drive multiple corresponding first bevel gears 1241 to rotate. Through the transmission of the synchronous belt 125, the corresponding drive wheel 124 rotates. As the drive wheel 124 rotates, the connecting shaft 123 drives the synchronous gear 1231 to rotate. The synchronous gear 1231 meshes with the gear teeth 143 on the adjacent annular slider 14, so that the annular slider 14 can rotate over the second arc-shaped notch 141. Multiple annular sliders 14 rotate synchronously, so that multiple first cutters 22 and second cutters 23 can simultaneously cut the insulation layer of multiple cable outer walls, thereby improving processing efficiency.

[0032] See Figures 1 to 4 As shown, multiple pushing mechanisms 5 for moving cables are also equidistantly arranged on the vertical plate 1; each pushing mechanism 5 includes a fourth hydraulic rod 51 and a fixing ring 52; the fourth hydraulic rod 51 is horizontally arranged on the vertical plate 1 and located below the corresponding annular guide rail 13, the driving direction of the fourth hydraulic rod 51 is perpendicular to the plane of the vertical plate 1, the end of the fourth hydraulic rod 51 is provided with a fixing ring 52, the fixing ring 52 is provided with a third arc-shaped notch 521 for the cable to pass through, and three fifth hydraulic rods 522 are radially arranged on the inner wall of the fixing ring 52 along the axial direction, the end of each fifth hydraulic rod 522 is provided with a U-shaped plate 523, and each U-shaped plate 523 is rotatably provided with an abutment roller 524.

[0033] Each U-shaped plate 523 is also equipped with a drive motor for driving the abutment roller 524 to rotate. The cable moves through the third arc-shaped notch 521 into the fixed ring 52. Then, multiple fifth hydraulic rods 522 abut and fix the cable, so that the cable can be located at the center of the fixed ring 52. At this time, the fixed ring 52 and the corresponding annular guide rail 13 above it are coaxially arranged. Then, the abutment roller 524 is rotated by pushing the motor, so that the cable can move along its axis, which facilitates the cutting of the cable end, thereby further simplifying the operation steps and improving the installation efficiency. After the copper lug at the end of the cable is installed, the position of the cable is adjusted by the fourth hydraulic rod 51 so that it can be moved into the cabinet, which facilitates the staff to connect the copper lug.

[0034] See Figure 4 As shown, the bottom of the vertical plate 1 is provided with multiple semi-circular grooves 17 at equal intervals, and the bottom edge of the fixing ring 52 is provided with a guide roller 525.

[0035] The semi-circular groove 17 is provided to guide the cable and limit it within the corresponding semi-circular groove 17. The guide roller 525 is provided to avoid rigid contact between the cable and the fixing ring 52, thus ensuring the integrity of the cable.

[0036] See Figure 1 As shown, a push handle 18 is also provided on the vertical plate 1.

[0037] The presence of a push handle 18 facilitates the adjustment of the position of the vertical plate 1 by staff, making it easier to push the vertical plate 1.
