Description

Technical Field

[0001] The present invention relates to the technical field of assembly and manufacturing of circuit breakers, in particular to a primary-secondary fusion column mounted circuit breaker and assembly equipment thereof. Background Art

[0002] A primary / secondary integrated pole-mounted circuit breaker is a circuit breaker that deeply integrates primary and secondary equipment. It plays a vital role in the power distribution network of the power system. It can effectively control and protect the lines of the distribution network, ensuring the reliability and safety of power supply.

[0003] The prior art discloses a Chinese patent with publication number CN 220358023 U: a primary-secondary fusion pole-mounted circuit breaker, and discloses a circuit breaker and an operating assembly disposed inside the circuit breaker, through which the circuit breaker is quickly mounted on an external mounting frame.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] The pole-mounted circuit breaker of the present invention is a type of power electronic component in the smart grid industry. Assembling the arc extinguishing chamber and the mechanism box of the pole-mounted circuit breaker is a process in the production of the pole-mounted circuit breaker and is part of the circuit breaker manufacturing process.

[0023] The assembly equipment of the present invention belongs to the intelligent manufacturing equipment industry and is a part of the pole-mounted circuit breaker production equipment, and is used for automatically plugging and installing the arc extinguishing chamber and the mechanism box of the pole-mounted circuit breaker.

[0024] Refer to the instruction manual Figure 1-Figure 2 The present invention provides a primary-secondary fusion column-mounted circuit breaker, comprising a main body 1, which is composed of a mechanism box 101 and an arc extinguishing chamber 102. The arc extinguishing chamber 102 is movably plugged into the top of the mechanism box 101. An L-shaped plate 105 is provided on the outside of the mechanism box 101. Two pull posts 103 that movably penetrate corresponding sides of the mechanism box 101 are fixedly provided on the inside of the L-shaped plate 105. One end of one of the pull posts 103, located inside the mechanism box 101, movably penetrates the bottom end of the arc extinguishing chamber 102. The other pull post 103, located inside the mechanism box 101, is fixedly provided with a baffle at one end. A buffer ring 106 made of rubber is fixedly sleeved on the ends of the two pull posts 103 located outside the mechanism box 101. A plug post 104 is fixedly provided on the inner side of the mechanism box 101 at the position of the pull post 103 that passes through the arc extinguishing chamber 102. The end of the plug post 104 close to the arc extinguishing chamber 102 is separated from the arc extinguishing chamber 102. The plug post 104 is movably plugged into the end of the corresponding pull post 103. A straight spring 1 that fixes the mechanism box 101 and the baffle is sleeved on the outside of one of the pull posts 103. When the L-shaped plate 105 is in contact with the outer wall of the mechanism box 101, the straight spring 1 is in a stretched state, and the buffer ring 106 is in an extruded contact state with the mechanism box 101. The end of the pull post 103 at the upper end passes through the through hole at the bottom end of the arc extinguishing chamber 102 and is sleeved on the outside of the plug post 104, which can improve the stability of the arc extinguishing chamber during plug-in installation. Furthermore, two concentric annular grooves can be opened at the position corresponding to each arc extinguishing chamber 102 on the upper end surface of the mechanism box 101, and glue can be applied at the position where each arc extinguishing chamber 102 contacts the upper end surface of the mechanism box 101, and the glue is placed between the two annular grooves. The two annular grooves can be used to receive glue overflowing during the process of pressing and bonding the arc extinguishing chamber 102. The setting of the adhesive structure can, on the one hand, further improve the stability of the plug-in installation of the arc extinguishing chamber 102, and on the other hand, form a waterproof sealing layer.

[0025] Refer to the instruction manual Figure 3-Figure 4The pole-mounted circuit breaker also includes a mounting base 2, which includes a base frame 201. The base frame 201 is fixed with a mounting frame at one end opposite to the mechanism box 101. The two mounting frames are detachably mounted by locking bolts. A straight rod 202 is fixed to the middle of the inner side of the base frame 201. The outer side of the straight rod 202 is provided with two L-shaped seats 203 slidably mounted inside the base frame 201. Both ends of the outer side of the straight rod 202 are provided with straight springs that are fixedly connected to the base frame 201 and the corresponding L-shaped seats 203. The two L-shaped seats A handle is fixedly provided on each side opposite to the two L-shaped seats 203. Furthermore, an anti-slip assembly 204 is provided on the opposite end of each L-shaped seat 203. The anti-slip assembly 204 includes a swing groove 2041 provided at the end of the horizontal section of the corresponding L-shaped seat 203. A swing plate 2042 is rotatably installed inside the swing groove 2041 through a rotating rod. An arc rod 2043 is fixed in the middle of the swing groove 2041 and movably penetrates the swing plate 2042. An arc spring is sleeved on the outer side of the arc rod 2043 to fixedly connect the inner wall of the swing groove 2041 and the swing plate 2042. When the pendulum plate 2042 is in the Figure 4 In the state shown, the arc spring is still in a compressed state. In this state, the portion of the top of the swing plate 2042 extending out of the swing slot 2041 is set as an inclined portion, and the portion of the lower end of the swing plate 2042 extending out of the swing slot 2041 is provided with a gripping groove to facilitate operation during the installation of the pole-mounted circuit breaker. It should be noted that, in the process of installing the arc extinguishing chamber 102 on the mechanism box 101, the L-shaped plate 105 is pulled outward to allow the pull column 103 at the upper end to break away from the position blocking the arc extinguishing chamber 102. Then, after the arc extinguishing chamber 102 is plugged and installed, it is fitted with the upper end surface of the mechanism box 101, and the portion between the two arc-shaped grooves is coated with glue. Then, the arc extinguishing chamber 102 is inserted into the top of the mechanism box 101, so that the through-hole at the bottom end of the arc extinguishing chamber 102 is aligned with the pull column 103. Finally, the force applied to the L-shaped plate 105 is removed, and the pull column 103 is inserted into the through-hole under the restoring force of the straight spring 1, thereby completing the installation between the arc extinguishing chamber 102 and the mechanism box 101. In the process of installing the pole-mounted circuit breaker to the specified position, the two L-shaped seats 203 are pulled to move away from each other until the distance between them is greater than the support frame that supports the pole-mounted circuit breaker. Then, the force applied to the two L-shaped seats 203 is removed, and the two L-shaped seats 203 are allowed to move toward each other under the restoring force of the corresponding straight springs. During the process of the two L-shaped seats 203 moving toward each other, the support frame will squeeze the swing plate 2042 on the corresponding L-shaped seat 203 and push the swing plate 2042 to the side away from the corresponding handle, causing the arc spring to continue to be compressed until the support frame passes over the corresponding swing plate 2042. The swing plate 2042 will then return to its original position under the restoring force of the corresponding arc spring. Figure 4The state shown is shown, and the swing plate 2042 protruding from the corresponding swing slot 2041 in this state is used to block it to prevent dislocation during use.

[0026] Example 1: Refer to the attached instructions Figure 5 and Figure 7 The present invention provides an assembly device for a primary and secondary fusion column mounted circuit breaker, which is used to assemble the main body 1 of the primary and secondary fusion column mounted circuit breaker, including a frame 3, a material frame 4 and a conveyor frame 5 for installing a conveyor belt are fixed at both ends of the top of the frame 3, wherein the material frame 4 is set as a stepped structure, and a bracket for assisting in fixing the arc extinguishing chamber 102 to be installed is provided on it, and side plates fixed to the top of the frame 3 are provided on both sides of one end of the conveyor frame 5, which can be used to prevent the mechanism box 101 on the conveyor belt from being damaged. Position correction is performed to ensure that the mechanism box 101 is accurately transported to the installation position of the arc extinguishing chamber 102. In addition, a plurality of equally spaced balls can be rolled and embedded on both sides of the top of the conveying frame 5 (a conventional setting for reducing friction, not specifically shown in the drawings) to reduce the friction when the mechanism box 101 is moved to the installation position of the arc extinguishing chamber 102. A clamping mechanism 7 and a correction mechanism 8 are respectively installed on both sides of the conveying frame 5. A reciprocating drive mechanism 6 for driving the clamping mechanism 7 to perform reciprocating steering motion is provided between the material rack 4 and the conveying frame 5; A positioning mechanism 10 for positioning the mechanism box 101 is provided on the outside of the conveying frame 5 at a position corresponding to the deviation correcting mechanism 8 . A push-opening mechanism 11 for pulling the pull column 103 outward is also provided on the outside of the conveying frame 5 .

[0027] It should be noted that the present invention uses a conveyor belt to transport the mechanism box 101 to the installation station of the arc extinguishing chamber 102, and uses a positioning mechanism 10 to position the mechanism box 101 transported to the installation station of the arc extinguishing chamber 102. At the same time, the arc extinguishing chamber 102 to be installed on the material rack 4 is clamped by the reciprocating drive mechanism 6 and transported to the installation station of the arc extinguishing chamber 102. After the arc extinguishing chamber 102 and the mechanism box 101 are both transported to the installation station, the plug-in installation of the arc extinguishing chamber 102 and the mechanism box 101 is completed with the assistance of the top-opening mechanism 11.

[0028] Specifically, if Figure 6 and Figure 8-Figure 9As shown, the reciprocating drive mechanism 6 includes a cross slot 64 provided on the material rack 4 and a limiting frame 612 fixed to the top of the frame 3. A cross block 65 is slidably installed inside the cross slot 64. A screw 66 is threadedly connected to the cross block 65. One end of the screw 66 movably passes through the limiting frame 612. A limiting slot is provided on the inside of the limiting frame 612. A ring plate slidably connected to the inside of the limiting slot is fixed on the outside of the screw 66. The limiting slot and the cross slot 64 cooperate to ensure that the screw 66 can perform stable lifting and lowering movements. The screw 66 is driven to rotate by a motor installed on the outside of the cross block 65. The reciprocating drive mechanism 6 also includes rails 61 fixed to both sides of the top of the frame 3, and a support plate 62 is provided between the two rails 61, which is threadedly sleeved on the outside of the screw 66, and a ball 63 is fixed at both ends of the support plate 62 to slide in the corresponding rail 61. A gear seat 67 fixed to the top of the frame 3 is also provided between the two rails 61. A rotating shaft is installed in the middle of the support plate 62 through a bearing for through-type rotation, and a gear 1 68 corresponding to the gear seat 67 is fixed to the bottom end of the rotating shaft. In the process of gear 1 68 moving along the rail 61 with the support plate 62 driven by the screw 66, it will mesh with the gear seat 67 after moving to the area corresponding to the gear seat 67, so that after being driven by the gear seat 67, the clamping mechanism 7 installed on the top of the support plate 62 will turn 180 degrees, so that the clamped arc extinguishing chamber 102 to be installed faces the installation position; The reciprocating drive mechanism 6 also includes a fixed block 610 fixed on the top of the frame 3 and a frame 69 that movably passes through the conveyor frame 5. A guide column 611 that movably passes through the fixed block 610 is fixed on the side of the frame 69 facing the fixed block 610. A straight spring 2 that fixes the frame 69 and the fixed block 610 is sleeved on the outside of the guide column 611. The top end of the frame 69 close to the fixed block 610 is tilted downward.

[0029] It should be noted that, in the process of using the reciprocating drive mechanism 6 to drive the clamping mechanism 7 to reciprocate between the installation station of the arc extinguishing chamber 102 and the material rack 4 carrying the arc extinguishing chamber 102 to be installed, after the clamping mechanism 7 clamps the arc extinguishing chamber 102 pre-placed on the material rack 4, the motor is started to drive the screw 66 to move along the track 61, so that the support plate 62 carrying the clamping mechanism 7 approaches the installation station of the arc extinguishing chamber 102 under the rotation of the screw 66, and when passing through the area of the tooth seat 67, the tooth seat The meshing setting between 67 and gear 1 68 will cause gear 1 68 to rotate 180°, allowing the clamping mechanism 7 that clamps the arc extinguishing chamber 102 to be installed to rotate 180° synchronously, so that the clamped arc extinguishing chamber 102 to be installed faces the installation station. Conversely, after the installation is completed, as the screw 66 rotates in the opposite direction, the clamping mechanism 7 will retreat with the support plate 62, and when passing through the area corresponding to the tooth seat 67, it will change direction again, so that the clamping part of the clamping mechanism 7 faces the direction of the material rack 4 and waits for the next round of clamping.

[0030] Specifically, if Figure 8-Figure 9 and Figure 11 As shown, the clamping mechanism 7 includes a U-shaped frame 71 fixed to the top of the rotating shaft, a dovetail groove is provided on the inside of the U-shaped frame 71, a dovetail block 72 is slidably connected to the inside of the dovetail groove, and a U-shaped frame 73 is fixed on one end of the dovetail block 72 extending to the outside of the dovetail groove, which fits the inside of the U-shaped frame 71. The arrangement of the dovetail groove and the dovetail block 72 ensures that the U-shaped frame 73 can move up and down stably. A cylinder 74 is fixedly installed on the top of the U-shaped frame 71 with a telescopic end fixedly connected to the U-shaped frame 73. The U-shaped frame 73 A trapezoidal block 711 is fixedly provided at the middle of the bottom, and a through slot is provided at the bottom end of the U-shaped frame 71, facing the trapezoidal block 711. When the second straight spring is in its natural state, the highest point of the end of the frame 69 close to the fixed block 610 intersects with the side of the through slot close to the fixed block 610, so that during the downward movement of the trapezoidal block 711, it can squeeze the inclined surface of the frame 69, thereby pushing the frame 69 to move axially along the screw rod 66. In the initial state, the bottom end of the trapezoidal block 711 is completely hidden in the through slot. A cylinder 2 75 is fixedly installed on the inner side of the U-shaped frame 73, and a sliding plate 76 is fixedly connected to the telescopic end of the cylinder 2 75. A straight tooth plate 77 is fixedly provided on one side of the sliding plate 76. In this case, the number of straight tooth plates 77 is illustrated as three for example (the same below), wherein a sliding groove is provided on the inner side of the U-shaped frame 73 for limiting the linear motion of the sliding plate 76, and a rotating rod 1 is rotatably installed at the positions on both sides of the inner side of the U-shaped frame 73 corresponding to the straight tooth plate 77. A gear 2 79 meshing with the corresponding straight tooth plate 77 is fixedly sleeved on the middle part of the outer side of the rotating rod 1, and a clamping frame 78 is fixed between the outer sides of the two ends of the rotating rod 1, and a plurality of rubber rollers 710 are rotatably installed on the inner sides of the two clamping frames 78. The setting of the rubber roller 710 can be used to prevent the clamped arc extinguishing chamber 102 to be installed from sliding in the vertical direction, and at the same time, it will not affect the circumferential orientation adjustment of the clamped arc extinguishing chamber 102.

[0031] It should be noted that in the process of clamping the arc extinguishing chamber 102 using the clamping mechanism 7, when the support plate 62 moves until the arc extinguishing chamber 102 to be clamped enters the clamping range of the clamping frame 78, the cylinder 2 75 is used to pull the sliding plate 76 in the direction away from the clamping frame 78, thereby driving the three straight tooth plates 1 77 to move synchronously. During this period, as the straight tooth plate 1 77 moves, the corresponding two gears 2 79 will be driven to rotate at the same time, thereby driving the two clamping frames 78 to close (the initial state is assumed to be open) and move, thereby clamping the target arc extinguishing chamber 102, and then transporting it to the designated workstation under the movement of the support plate 62. Conversely, after the transportation of the arc extinguishing chamber 102 is completed, the sliding plate 76 will be pushed toward the clamping frame 78 by the cylinder 2 75, so as to drive the two clamping frames 78 to open through the moving straight tooth plate 1 77, thereby releasing the clamping state of the arc extinguishing chamber 102.

[0032] Specifically, if Figure 8-Figure 9 and Figure 12 As shown, the correction mechanism 8 includes a through slot 81 that runs through the frame 69 and a vertical frame 82 fixed to the top of the frame 3. The setting of the through slot 81 can ensure that the existence of the vertical frame 82 will not affect the movement of the frame 69. The top of the vertical frame 82 is fixedly connected to a U-shaped frame 83. The inside of the frame 69 is fixed with a straight tooth plate 84 that is movable through the U-shaped frame 83. Among them, an infrared rangefinder can be set inside the frame 69 to measure the distance between the frame 69 and the U-shaped frame 83 to confirm the fire extinguisher to be installed. Whether the arc chamber 102 completes the correction action, a rotating rod 2 is rotatably installed at the positions on both sides of the straight tooth plate 2 84 on the inner side of the U-shaped frame 2, and a gear 3 85 is fixedly sleeved on the middle part of the outer side of the rotating rod 2, which is engaged with the corresponding straight tooth plate 2 84. A correcting plate 86 is fixed between the outer sides of the two ends of the rotating rod 2, wherein the height of the correcting plate 86 is much larger than the horizontal section diameter of the arc extinguishing chamber 102, so that in the process of clamping the arc extinguishing chamber 102 and moving downward, the correcting plate 86 can move the arc extinguishing chamber 102 for range adjustment.

[0033] It should be noted that, in the process of using the deviation correction mechanism 8 to correct the deviation of the arc extinguishing chamber 102 transported to the designated position, when the arc extinguishing chamber 102 to be installed moves to the designated position with the support plate 62, the rotation of the screw 66 is stopped, and then the cylinder 1 74 pushes the U-shaped frame 1 73 to move downward along the dovetail groove, thereby driving the trapezoidal block 711 to move downward synchronously. During this process, when the bottom end of the trapezoidal block 711 passes through the through groove and contacts the inclined surface of the frame 69 near the end of the fixed block 610, as the trapezoidal block 711 continues to move downward, it will gradually move to the left (refer to Figure 9 ) pushes the frame 69, and when the frame 69 moves to the left, it drives the straight tooth plate 2 84 to move synchronously. The straight tooth plate 2 84 moving to the left pulls the corresponding two gears 3 85 to rotate, thereby driving the corresponding two correcting plates 86 to move toward each other. The two correcting plates 86 moving toward each other are used to move the horizontal section on the arc extinguishing chamber 102 in the same direction as the axis of the screw 66; During the above-mentioned correction process, when the infrared rangefinder detects that the distance between the end of the frame 69 away from the fixed block 610 and the U-shaped frame 83 reaches a certain value (the correction of the arc extinguishing chamber 102 is completed), it will transmit a signal to the control end, and the control end will control the top opening mechanism 11 to take action. Moreover, during the corresponding action of the top opening mechanism 11, it will pull the L-shaped plate 105 outward to allow the pull column 103 at the upper end to break away from the position blocking the arc extinguishing chamber 102. During this period, the arc extinguishing chamber 102 continues to move downward and is plugged into the top of the mechanism box 101, and the through hole at the bottom end of the arc extinguishing chamber 102 is opposite to the pull column 103. Subsequently, the force applied to the L-shaped plate 105 is removed, and the pull column 103 is inserted into the through hole under the action of the restoring force of the straight spring 1, thereby completing the installation between the arc extinguishing chamber 102 and the mechanism box 101.

[0034] Specifically, if Figure 8 As shown, the locking mechanism 10 includes four cylinders 1002 fixed on the top of the frame 3 and distributed in a rectangular array. The telescopic end of each cylinder 1002 is fixed with a lifting plate 1001, and the top of each lifting plate 1001 is fixed with a locking column 1003.

[0035] It should be noted that after the mechanism box 101 moves to the installation station with the conveyor belt, the control end will control the cylinder four 1002 to lift the lifting plate 1001 upward, so that the clamping column 1003 at the top of the lifting plate 1001 is inserted into the mounting hole on the mounting frame of the mechanism box 101, completing the precise positioning of the mechanism box 101 and ensuring the smooth progress of the arc extinguishing chamber 102 plug-in process.

[0036] Specifically, if Figure 8 As shown, the top opening mechanism 11 includes a side frame 111 fixed to the top of the frame 3, and a cylinder 5 112 is fixedly installed on one side of the side frame 111. The telescopic end of the cylinder 5 112 is fixedly connected to a trapezoidal plate 113, and the trapezoidal plate 113 extends from one end of the side frame 111 to the inner side of the L-shaped plate 105.

[0037] It should be noted that, in the above-mentioned correction process, when the infrared rangefinder detects that the distance between the end of the frame 69 away from the fixed block 610 and the U-shaped frame 2 83 reaches a certain value, it will transmit a signal to the control end, and the control end will control the cylinder 5 112 to push the trapezoidal plate 113 toward the direction of the L-shaped plate 105, and use the forward-moving trapezoidal plate 113 to push the L-shaped plate 105 outward, thereby pulling the pull column 103 at the upper end out of the position blocking the arc extinguishing chamber 102. This process requires the positioning of the mechanism box 101 on the installation station by relying on the positioning mechanism 10.

[0038] Example 2: Refer to the attached instructions Figure 5 and Figure 10As shown, the present invention also provides an assembly device for a primary and secondary fusion column-mounted circuit breaker, a gluing mechanism 9 is further provided between the two rails 61, the gluing mechanism 9 includes a second cross slot 91 provided on the frame 3, the length of the second cross slot 91 along the axis direction of the screw 66 is greater than the length of the recessed area on the rail 61, a cross seat 92 is slidably connected inside the second cross slot 91, a cross seat 92 is fixedly connected to the top of the cross seat 92 with a horizontal plate 93 that fits the upper end surface of the frame 3, a gluing head 98 is fixedly installed on the top of the horizontal plate 93, and three groups of gluing heads 98 are provided, and they correspond one to one with the clamped arc extinguishing chamber 102, and each group has a plurality of them evenly distributed in a ring shape, wherein an infrared rangefinder for detecting the distance between the support plate 62 and the frame 3 is also installed at the bottom end of the support plate 62, so as to accurately control the gluing head 98 to work; Guide grooves 95 are provided on both sides of the cross seat 92. A guide bar 96 fixedly connected to the cross plate 93 is slidably connected inside each guide groove 95. A guide rod 97 that movably passes through the cross seat 92 is fixed inside the cross groove 91. A straight spring 4 that is fixedly connected to the inner wall of the cross groove 91 and the cross seat 92 is also provided on the outside of the guide rod 97. When the cross seat 92 is in the position shown in FIG. Figure 10 In the position shown, the straight spring four is still in a compressed state, and the bottom end of the cross seat 92 is fixedly mounted with a cylinder three 94 whose telescopic end is fixedly connected to the horizontal plate 93.

[0039] It should be noted that, in the process of using the reciprocating drive mechanism 6 to drive the support plate 62 to move along the track 61, when the clamping mechanism 7 clamping the arc extinguishing chamber 102 to be installed moves to the left (see Figure 9 ) moves, the support plate 62 will move toward the recessed area along the horizontal section of the front end (the end close to the rack 4) of the track 61. When the infrared rangefinder at the bottom of the support plate 62 detects that the support plate 62 has just sunk to the lowest point, it will transmit a signal to the control end, which will control the cylinder 3 94 to lift the horizontal plate 93 upward until the dispensing head 98 is close to the glue coating area on the arc extinguishing chamber 102. Then, as the support plate 62 continues to move, the U-shaped frame 71 will push the horizontal plate 93 to the left and compress the straight spring 4. During this period, After the dispensing head 98 rises to the specified height, it dispenses glue to the glued area on the corresponding arc extinguishing chamber 102. When the infrared rangefinder detects that the support plate 62 moves upward, the cylinder 3 94 drives the cross plate 93 to move downward and reset, and the U-shaped frame 71 continues to push the cross plate 93 to the left. When the cross plate 93 drops to the point where it is completely offset from the U-shaped frame 71, the cross seat 92 is reset under the restoring force of the straight spring 4, and the support plate 62 just transitions from the recessed area to the rear end of the track 61. In addition, when the pallet 62 moves along the rear end of the track 61, the U-shaped frame 71 will turn 180 degrees when passing the area where the gear seat 67 is located, so that the arc extinguishing chamber 102 to be installed faces the installation station. In the process of the pallet 62 moving to the right and resetting, when the infrared rangefinder at the bottom of the pallet 62 detects that the pallet 62 has just sunk to the lowest point, although the signal will be transmitted to the control end, the control end will control the cylinder three 94 not to move. Only when the arc extinguishing chamber 102 to be installed is clamped and moved to the left, the lifting cross plate 93 will move upward to perform the dispensing operation.
