Description

Technical Field

[0001] The invention relates to the field of electrical equipment assembly, in particular to a pole-mounted circuit breaker assembly tool. Background Art

[0002] A pole-mounted circuit breaker is a circuit breaker installed and operated on a utility pole. It protects the safe operation of the power system, enables segmented and automated control of the power system, improves the efficiency and reliability of the power system, and reduces its operating costs. A pole-mounted circuit breaker consists of a mounting bracket, an insulating support, a switching power supply, and a switching handle. The mounting bracket has three supports spaced evenly apart on the top, and a flange seat is provided at the bottom of the insulating support. The flange seat is bolted to the supports, completing the assembly of the mounting bracket and the insulating support. Assembly tooling is often used to assist in ensuring faster and more convenient assembly of the insulating support and mounting bracket.

[0003] For example, Chinese invention patent publication number CN115026749B provides a fixture for auxiliary assembly of a pole-mounted circuit breaker. The assembly unit provided in this patent uses a support rod and an actuator sleeve to limit the position of the insulating pillar, preventing it from shaking and shifting during assembly, thereby improving assembly accuracy. Furthermore, the assembly unit uses the actuator sleeve to screw a bolt into the threaded hole of the mounting bracket, thereby assisting in the assembly of the mounting bracket and the insulating pillar. This eliminates the need for manual assembly and is convenient to operate.

[0004] However, the above patent cannot assist in the installation of insulating pillars that are installed at an angle on the upper part of the mounting bracket. For example, the upper part of the mounting bracket of the pole-mounted circuit breaker model ZW8-12 / 630A has structures that are inclined to both sides, so that the upper parts of the insulating pillars installed on both sides are in a state where their upper parts are far away from each other. In addition, the auxiliary equipment in the prior art can only perform initial adjustment on the position of the insulating pillars, and it is difficult to automatically make timely adjustments according to the specific conditions of the mounting bracket. When there is a large tolerance on the mounting bracket, manual adjustment of the auxiliary equipment is required, which greatly reduces the assembly efficiency and is not conducive to the precise alignment of the insulating pillars and the mounting bracket, resulting in poor assembly effect.

[0032] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0033] See Figure 1 and Figure 2 A pole-mounted circuit breaker assembly tool comprises an assembly base 1, the upper part of the assembly base 1 is an L-shaped structure, the upper part of the horizontal section of the assembly base 1 is provided with a bracket alignment component 2 for aligning and fixing the mounting bracket of the pole-mounted circuit breaker, and the front part of the vertical section of the assembly base 1 is provided with a pillar alignment component 3 for aligning and mounting the insulating pillar of the pole-mounted circuit breaker on the upper part of the mounting bracket; when it is necessary to assemble the mounting bracket of the pole-mounted circuit breaker and the insulating pillar, the insulating pillar is first clamped on the pillar alignment component 3, and then the mounting bracket is placed inside the bracket alignment component 2, and then the pillar alignment component 3 is pre-adjusted so that the insulating pillar corresponds to the support position of the mounting bracket, and then the pillar alignment component 3 assists the insulating pillar in aligning to the support at the corresponding position, thereby completing the precise alignment of the insulating pillar and the mounting bracket.

[0034] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7The pillar alignment component 3 includes a main support plate 31 that is slidably arranged at the front of the vertical section of the assembly seat 1, and a sub-support plate 32 is symmetrically arranged on the left and right sides of the main support plate 31 and slides left and right. An adjustment plate 34 is provided in front of the sub-support plate 32, and a fine-tuning component 33 is provided in front of the adjustment plate 34. The front of the main support plate 31 is installed with a sliding frame 311. The fine-tuning component 33 includes a fine-tuning frame 331 that is rotatably arranged in front of the adjustment plate 34. The interiors of the fine-tuning frame 331 and the sliding frame 311 are both provided with a clamping component 35 that slides along their length directions. The clamping component 35 includes a sliding frame 351 that slides inside the fine-tuning frame 331 and the sliding frame 311 along their length directions respectively. The fine-tuning frame 331 and the upper left side of the sliding frame 311 are both elastically slid left and right with a locking device. The locking block 355 is provided on the right side with an inclined surface inclined to the left at the bottom, and a rectangular groove for inserting the locking block 355 is provided on the left side of the sliding frame 351. When the mounting bracket of the pole-mounted circuit breaker and the insulating pillar need to be assembled, the sliding frame 351 is moved upward along the length direction of the fine-tuning frame 331 and the sliding frame 311 at the corresponding positions, so that the sliding frame 351 moves to contact the locking block 355, so that the sliding frame 351 and the inclined surface of the locking block 355 cooperate, and then the sliding frame 351 pushes the locking block 355 at the corresponding position to the left. When the sliding frame 351 moves to the uppermost position, the locking block 355 moves to the right to the inside of the rectangular groove under the action of its own elastic force, thereby fixing the sliding frame 351 at the uppermost position.

[0035] See Figure 3 、 Figure 5 and Figure 7 When the cam 352 is in the closed position, the cam 352 is in the closed position and the cam 353 is in the closed position.

[0036] See Figure 1 、 Figure 3 and Figure 4A nut 26 is rotatably provided on the left front portion of the main support plate 31, and a one-way threaded rod 261 is connected to the inner thread of the nut 26. A guide column is provided on the right front portion of the main support plate 31 for sliding back and forth. The one-way threaded rod 261 and the front side of the guide column are jointly slid up and down with a vertical plate 27; when the insulating pillar is clamped and locked on the clamping claw 353, the nut 26 is rotated to drive the one-way threaded rod 261 to move forward, and the one-way threaded rod 261 drives the vertical plate 27 to move forward, and the guide column is used to keep the vertical plate 27 in a vertical state at all times, so that the vertical plate 27 moves forward until its front side is pressed against the rear side of the flange seat of the insulating pillar, so as to facilitate the determination of the position of the mounting bracket.

[0037] See Figure 1 、 Figure 2 and Figure 6 , the bracket alignment component 2 includes a conveyor belt 21 that is freely rotatable and arranged inside the horizontal section of the assembly seat 1, and a lifting frame 22 is provided inside the horizontal section of the assembly seat 1 to slide up and down. The lifting frame 22 is located on the lower side of the conveyor belt 21, and the upper left and right sides of the lifting frame 22 are rotatably provided with moving rollers 23. The moving rollers 23 are respectively located on the left and right sides of the conveyor belt 21. The left and right sides of the vertical section of the assembly seat 1 are symmetrical and slidingly provided with centering plates 25. A lifting hydraulic cylinder 11 is installed at the lower part of the horizontal section of the assembly seat 1, and the piston rod of the lifting hydraulic cylinder 11 is connected to the lower part of the lifting frame 22. A two-way hydraulic cylinder 12 is installed at the rear of the vertical section of the assembly seat 1, and the piston rods of the two-way hydraulic cylinder 12 are respectively connected to the centering plates 25 at the left and right positions; when the vertical section After the straight plate 27 is pressed against the flange seat, the mounting bracket is placed on the conveyor belt 21, and then the piston rod of the lifting hydraulic cylinder 11 is extended to drive the lifting frame 22 to move upward. The lifting frame 22 lifts the mounting bracket through the moving roller 23 until its lower side is no longer in contact with the conveyor belt 21. Then, the piston rod of the bidirectional hydraulic cylinder 12 is retracted to drive the left and right centering plates 25 to approach each other, so that the left and right centering plates 25 push the mounting bracket to move to the center position of the assembly seat 1, and the moving roller 23 allows the heavier mounting bracket to move left and right more smoothly. Then, the piston rod of the lifting hydraulic cylinder 11 is retracted to drive the mounting bracket to move downward until it is placed on the conveyor belt 21, thereby completing the determination of the left and right positions of the mounting bracket.

[0038] Continue reading Figure 1 、 Figure 2 and Figure 6, the left and right sides of the horizontal section of the assembly seat 1 are provided with pushers 24 for sliding forward and backward. The left and right sides of the front of the pusher 24 are symmetrically positioned and are provided with sliding rods 241 for sliding left and right. The sliding rods 241 are fixed in position by screws. The rear part of the vertical section of the assembly seat 1 is provided with a pushing hydraulic cylinder 13. The pushing hydraulic cylinder 13 is located at the lower side of the two-way hydraulic cylinder 12. The piston rod of the two-way hydraulic cylinder 12 is connected to the pusher 24; after the left and right positions of the mounting bracket are determined, the two sliding rods 241 are moved in the direction of approaching each other, so that the sliding rods 241 move the front side of the mounting bracket. The position of the sliding rod 241 is locked by a screw, and then the piston rod of the hydraulic cylinder 13 is extended to drive the sliding rod 241 to move backward through the pushing member 24. When the sliding rod 241 moves, it pushes the mounting bracket backward, so that the mounting bracket moves backward to the rear side of the support in the middle position of its upper side against the front side of the vertical plate 27, so that the support of the mounting bracket and the flange seat of the insulating pillar are in the same vertical plane, thereby completing the adjustment of the front and rear position of the mounting bracket, and the conveyor belt 21 allows the heavier mounting bracket to move forward and backward more smoothly.

[0039] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The upper portion of the main support plate 31 is provided with a bidirectional screw 312 for rotation, and the upper portion of the auxiliary support plate 32 is provided with a sliding block 324 for sliding left and right. The two sections of the bidirectional screw 312 are respectively threadedly connected to the two sliding blocks 324. A pushing spring is provided between the left and right sides of the sliding block 324 and the left and right sides of the auxiliary support plate 32 at the corresponding position. Spring 325; after the position of the mounting bracket is locked, the bidirectional screw 312 is rotated to synchronously drive the two sliding blocks 324 to adjust the position left and right. The sliding block 324 drives the sub-support plate 32 at the corresponding position to adjust the position synchronously by pushing the spring 325, so that the sub-support plate 32 drives the insulating pillars on both sides to move to the position directly above the corresponding support through the fine-tuning component 33 and the clamping component 35 in turn, and then the inclination of the adjustment plate 34 is changed through the moving block 341 by rotating the up and down position adjustment screw rod 322, so that the adjustment plate 34 drives the insulating pillars on both sides to rotate to the same inclination as the support through the fine-tuning component 33 and the clamping component 35 in turn.

[0040] The specific principle of adjusting the inclination of the adjustment plate 34 is as follows: rotating the upper adjustment screw rod 322 drives the upper movable block 341 to move left and right. When the upper movable block 341 moves left and right, it drives the upper end of the adjustment plate 34 to swing left and right, thereby adjusting the angle of the upper end of the adjustment plate 34. Similarly, the lower adjustment screw rod 322 drives the lower end of the adjustment plate 34 to adjust the angle, and when the inclination of the adjustment plate 34 changes, the adjustment plate 34 drives the vertical distance between the two movable blocks 341 to change, so that the adjustment plate 34 drives the sliding seat 321 to move up and down through the lower movable block 341.

[0041] In this embodiment, two upper and lower adjustment screw rods 322 are used to adjust the angle of the adjustment plate 34, which can make the inclination adjustment range of the adjustment plate 34 on the auxiliary support plate 32 larger, and can make the adjustment plate 34 rotate with any point of itself as a fulcrum when changing the inclination, thereby eliminating the need to adjust the position of the auxiliary support plate 32 a second time, making the adjustment of the insulating pillar faster, thereby speeding up the assembly efficiency.

[0042] See Figure 3 and Figure 4 When the cam 322 is in the unlock position, the cam 323 is unlocked, and the cam 323 is unlocked, so that the cam 323 can be unlocked and the cam 323 can be unlocked.

[0043] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7When the cam 331 is in the upright position, the lever 332 is engaged with the lever 334 and the lever 335 is engaged with the lever 336 to move the lever 337 downwards, thereby releasing the lever 338. The support plates 331 are moved downwardly by the support plates 332, and the support plates 332 are moved downwardly by the support plates 333. The support plates 331 are moved downwardly by the support plates 334. The support plates 331 are moved downwardly by the support plates 333. The support plates 333 are moved downwardly by the support plates 333.

[0044] When the specific clamping rod 335 fine-tunes the inclination of the insulating pillar, when the clamping rod 335 on one side of the same clamping frame 333 first contacts the inclined surface of the mounting bracket, the piston rod of the telescopic hydraulic cylinder 14 drives the clamping frame 333 to continue to move downward, so that the reaction force of the mounting bracket on the clamping rod 335 pushes the clamping rod 335 on one side to move upward, and the clamping rod 335 on one side pushes the fine-tuning frame 331 to rotate through the center block 334 and the clamping frame 333. When the fine-tuning frame 331 rotates, the return spring 332 is compressed, so that the fine-tuning frame 331 rotates to drive the clamping rod 335 on the other side to press against the inclined surface of the mounting bracket.

[0045] Continue reading Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7The left rear part of the moving frame 333 is equipped with a moving cylinder 336, and the telescopic rod of the moving cylinder 336 is connected to the center block 334 on the left side. A connecting plate 3331 is rotatably provided on the middle part of the lower front side of the moving frame 333, and a synchronous plate 3351 is rotatably provided on the outer rear part of the tightening rod 335. The synchronous plates 3351 on both sides are hinged to the two ends of the connecting plate 3331 respectively. When the inclination of the insulating pillar is fine-tuned, the telescopic rod of the moving cylinder 336 is extended to drive the center block 334 on the left to move to the right, and the center block 334 on the left is connected to the connecting plate 3331 through the synchronous plate 3351. The cooperation of the connecting plate 3331 drives the center block 334 on the right to move synchronously to the left, so that the left and right center blocks 334 clamp the support between them, so that the reaction force of the support on the center block 334 adjusts the position of the secondary support plate 32 left and right through the supporting frame 333, so that the secondary support plate 32 compresses the push spring 325 at the corresponding position through the sliding block 324. At the same time, the supporting frame 333 drives the main support plate 31 to adjust its position up and down through the secondary support plate 32, so that the main support plate 31 compresses or releases the buffer spring 141, thereby corresponding the flange seat of the insulating support to the top of the support.

[0046] In this embodiment, when the flange seat of the insulating pillar corresponds to the top of the support, pull the locking block 355 to the left until its right end exits the rectangular groove of the sliding frame 351, and then slide the sliding frame 351 downward to place the flange seat of the insulating pillar on the upper part of the support of the mounting bracket through the clamping claw 353, and then manually tighten the bolts to complete the assembly of the insulating pillar and the mounting bracket.

[0047] When assembling the insulating pillar and the mounting bracket, the present invention includes the following steps: first, the sliding frame 351 is moved upward along the length direction of the fine-tuning frame 331 and the sliding frame 311 at the corresponding positions, so that the sliding frame 351 is fixed at the uppermost position, and then the insulating pillars are placed between the two clamping claws 353 at the corresponding positions, and then the double-rotation threaded rod 354 is rotated to drive the two clamping claws 353 at the corresponding positions to approach each other, so that the insulating pillars are clamped and locked by the clamping claws 353.

[0048] In the second step, rotating the nut 26 drives the vertical plate 27 forward through the one-way threaded rod 261 until its front side is pressed against the rear side of the flange seat of the insulating support, and the mounting bracket is placed on the conveyor belt 21. Then, the piston rod of the lifting hydraulic cylinder 11 is extended to drive the mounting bracket to lift, and then the piston rod of the two-way hydraulic cylinder 12 is retracted to drive the centering plate 25 to push the mounting bracket to the center position of the assembly seat 1. Then, the piston rod of the lifting hydraulic cylinder 11 is retracted to drive the mounting bracket to be placed on the conveyor belt 21, and then the two sliding rods 241 are moved in the direction of approaching each other and locked in position by screws. The piston rod of the pushing hydraulic cylinder 13 is extended to drive the sliding rod 241 to move backward, and the sliding rod 241 pushes the mounting bracket backward, so that the mounting bracket moves backward to the rear side of the support in the middle position of its upper side against the front side of the vertical plate 27, thereby completing the adjustment of the front and rear position of the mounting bracket.

[0049] In the third step, the bidirectional screw 312 is rotated to synchronously drive the insulating pillars on both sides to move to the position directly above the corresponding support. Then, the inclination of the adjustment plate 34 is changed by rotating the up and down position adjustment screw 322 through the moving block 341, so that the adjustment plate 34 drives the insulating pillars on both sides to rotate to the same inclination as the support through the fine-tuning component 33 and the clamping component 35 in turn.

[0050] In the fourth step, the piston rod of the telescopic hydraulic cylinder 14 is extended to drive the clamping rod 335 to move downward to the inclined surfaces on both sides of the mounting bracket, so that the two clamping rods 335 are both located on the inclined surfaces of the mounting bracket, so that the reaction force of the inclined surface of the mounting bracket on the clamping rod 335 pushes the fine-tuning frame 331 to rotate to a position where it is perpendicular to the inclined surface of the mounting bracket, so that the fine-tuning frame 331 drives the insulating support to swing to a position where it is perpendicular to the inclined surface of the mounting bracket through the clamping assembly 35.

[0051] In the fifth step, the telescopic rod of the actuating cylinder 336 is extended to drive the left and right center blocks 334 to clamp the support between them, so that the reaction force of the support on the center block 334 adjusts the position of the secondary support plate 32 left and right. At the same time, the actuating frame 333 drives the main support plate 31 to adjust its position up and down, so that the flange seat of the insulating support corresponds to the top of the support. Then, the sliding frame 351 is slid downward to place the flange seat of the insulating support on the upper part of the support of the mounting bracket through the clamping claw 353, and then the bolts are manually tightened to complete the assembly of the insulating support and the mounting bracket.
