Technical Field

[0001] This disclosure relates to the field of circuit breaker manufacturing, and more particularly to a circuit breaker thermal system component assembly apparatus. Background Technology

[0002] Handcart-type vacuum circuit breakers are mainly used in medium-voltage switchgear. They are equipped with a chassis at the bottom and can be moved inside the cabinet by means of a crank handle. They have three positions: working, test, and withdrawn. They can realize circuit switching and offline maintenance. They have integrated and complete anti-misoperation interlocking devices, making them safe and reliable to operate. Arc extinguishing relies on a vacuum bulb, which has excellent arc extinguishing performance and small size. They are commonly used switching equipment in power distribution systems.

[0003] In the existing technology, when assembling the vacuum circuit breaker body and the trolley chassis, since the trolley chassis needs to be installed at the bottom of the vacuum circuit breaker body, the vacuum circuit breaker body needs to be flipped over first to expose its bottom, then the trolley chassis is taken out and attached to the bottom of the vacuum circuit breaker body, then bolts are used to fix it, and finally the vacuum circuit breaker body is flipped back. The assembly process is labor-intensive and too cumbersome, and the assembly efficiency needs to be improved. Summary of the Invention

[0022] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0023] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0025] This invention provides, for example Figures 1-5 The circuit breaker thermal system component assembly device shown includes: an equipment bracket 1, horizontal moving units 2 on both sides of the equipment bracket 1, clamping and rotating units 3 connected to the bottom of the two horizontal moving units 2 for clamping and rotating the circuit breaker body, a body placement unit 4 on the inner side of the equipment bracket 1, and a handcart chassis conveying unit 5 on the top and bottom of the equipment bracket 1.

[0026] like Figure 2As shown, the equipment support 1 includes a platform 11 for providing an installation foundation for the handcart chassis conveying unit 5. The platform 11 has an installation groove 12 on the front side of its top, and a guide groove 13 distributed vertically in the middle of the inner side of the installation groove 12. Fixing frames 14 for providing an installation foundation for the horizontal moving unit 2 are fixedly installed on both sides of the top of the platform 11. Support legs 15 are fixedly installed at the four corners of the bottom of the platform 11. The bottom ends of the four support legs 15 are fixedly connected to a base 16. A mounting frame 17 for providing an installation foundation for the main body placement unit 4 is fixedly installed at the center of the top of the base 16. The platform 11, the fixing frame 14, the support legs 15 and the base 16 are all made of Q235B carbon structural steel, which has high strength, good rigidity and stable load-bearing capacity, and is not easily deformed.

[0027] like Figure 3 As shown, any set of horizontal moving units 2 includes a mounting plate 21 fixedly installed on the top of the inner side of the adjacent fixed frame 14. An electric push rod 22 is fixedly installed on the outer side of the mounting plate 21. The output shaft of the electric push rod 22 extends to the inner side of the mounting plate 21 and is fixedly connected to a moving plate 23. Both the moving plate 23 and the mounting plate 21 are made of 45 steel, which has high mechanical strength and good wear resistance and does not deform under the force of pushing and pulling. Both ends of the outer side of the moving plate 23 are fixedly provided with guide shafts A24 that slide through the mounting plate 21 through linear bearings. An extension arm 25 of the same material as the mounting plate 21 is fixedly connected to the bottom of the moving plate 23.

[0028] Thus, after the circuit breaker body is placed and positioned, the two electric push rods 22 drive the two moving plates 23 to move closer to each other, and the two moving plates 23 drive the two clamping seats 31 to move closer to each other through the two extension arms 25.

[0029] like Figure 3 As shown, any set of clamping and rotating units 3 includes a clamping seat 31 fixedly connected to the bottom end of the extension arm 25. The clamping seat 31 is made of aluminum alloy, which is lightweight and has sufficient rigidity. The inner side of the clamping seat 31 is provided with a rotating groove 32 and the outer side is provided with a rotating limiting groove 33 connected to the rotating groove 32. The inner side of the rotating groove 32 is provided with a wear-resistant nylon clamping disc 34 through a ball bearing. It is wear-resistant and will not damage the circuit breaker body. It has a moderate coefficient of friction and provides stable clamping without slippage. The outer side of the clamping disc 34 is fixedly provided with a limiting rod 35 that is slidably provided inside the adjacent rotating limiting groove 33. The inner side of the rotating limiting groove 33 is provided with a rotating shaft 36 fixedly connected to the adjacent clamping disc 34 through a ball bearing. The outer side of the rotating shaft 36 is fixedly sleeved with a long gear 37.

[0030] As the two clamping seats 31 move closer together, the two clamping discs 34 fit against the upper middle part of both sides of the circuit breaker body and clamp the circuit breaker body. When the long gear 37 rotates and drives the rotating shaft 36 to rotate counterclockwise, the two rotating shafts 36 drive the circuit breaker body to rotate counterclockwise synchronously through the two clamping discs 34 until the circuit breaker body is rotated 90 degrees counterclockwise and its bottom surface faces forward. At this time, the limiting rod 35 rotates from the top of the inner side of the rotating limiting groove 33 to the bottom of the inner side. Due to the limiting effect of the rotating limiting groove 33 on the limiting rod 35, the circuit breaker body cannot continue to rotate.

[0031] like Figure 4 As shown, the main placement unit 4 includes a hydraulic cylinder 41 fixedly installed at the bottom of the mounting frame 17. The output shaft of the hydraulic cylinder 41 extends to the top of the mounting frame 17 and is fixedly connected to a lifting plate 42 located inside the platform 11. A cast iron counterweight tray 410 is attached to the top of the lifting plate 42. Guide shafts B43 are fixedly installed on both sides of the bottom of the counterweight tray 410, which slide through the lifting plate 42 and the mounting frame 17 in the vertical direction via linear bearings. A rack A44 is fixedly installed at the bottom front end of the lifting plate 42. U-shaped seats 45 are fixedly installed on both sides of the top of the counterweight tray 410. A lifting block 46 is slidably installed in the vertical direction inside any one of the U-shaped seats 45. A rack B47 that meshes with the adjacent long gear 37 is fixedly installed on the top of the lifting block 46. A lifting limit groove 48 is opened on the side of the lifting block 46. A limit post 49 is slidably installed in the vertical direction on the top of the inner side of the lifting limit groove 48. The limit post 49 is fixedly installed inside the U-shaped seat 45.

[0032] Therefore, after the circuit breaker body is placed at the top center of the counterweight tray 410 and clamped, the hydraulic cylinder 41 can drive the lifting plate 42 to move downwards. When the lifting plate 42 moves downwards, the counterweight tray 410 moves downwards synchronously. Since the circuit breaker body is clamped between the two clamping plates 34 at this time, the circuit breaker body does not descend synchronously with the counterweight tray 410. When the counterweight tray 410 moves downwards, it drives the two U-shaped seats 45 to move downwards synchronously. When the U-shaped seats 45 move downwards, they drive the limiting post 49 to descend inside the lifting limiting groove 48. As the limiting post 49 continues to descend... As the circuit breaker descends, the limiting post 49 moves to the bottom of the inner side of the lifting limiting groove 48. At this time, a clearance space is formed between the counterweight tray 410 and the bottom of the circuit breaker body to avoid the circuit breaker body during counterclockwise rotation. As the lifting plate 42 continues to descend, the counterweight tray 410, under the action of gravity, drives the lifting block 46 to descend through the U-shaped seat 45 and the limiting post 49. When the lifting block 46 descends, it drives the rack B47 to descend synchronously. During the descent of the rack B47, it drives the long gear 37 to rotate, ultimately realizing the rotation of the circuit breaker body.

[0033] like Figure 5As shown, the handcart chassis conveying unit 5 includes two fixed plates 51 fixedly mounted on the front end of the bottom of the platform 11 and distributed along the front-rear direction. A coarse-pitch screw 52 is rotatably mounted between the two fixed plates 51 via a ball bearing. The coarse-pitch screw 52 allows the driven gear 53 to move a long distance with only a small rotation. The driven gear 53, which is adapted to the rack A44, is fixedly sleeved at the rear end of the outer side of the coarse-pitch screw 52. A sliding plate 54, which is slidably mounted inside the guide groove 13, is drivenly sleeved on the outer side of the coarse-pitch screw 52. A sliding device is fixedly connected to the top of the sliding plate 54. An L-shaped support 55 is located inside the mounting groove 12. An L-shaped groove 56 extending to the top of the L-shaped support 55 is provided on the back of the L-shaped support 55. A push beam 57 is slidably nested in the horizontal direction and a lifting beam 58 is slidably nested in the vertical direction inside the L-shaped groove 56. The front end of the top surface of the push beam 57 and the rear end of the bottom surface of the lifting beam 58 are both provided with inclined surfaces. The two inclined surfaces fit together. Slider blocks are fixedly provided at both ends of the push beam 57 and both ends of the lifting beam 58. Two sliding grooves are provided at both ends of the L-shaped support 55. Any one of the sliders is slidably located inside the adjacent sliding groove.

[0034] Therefore, the handcart chassis is placed on the top rear side of the L-shaped support seat 55, so that its bottom is in contact with the top of the lifting beam 58. Subsequently, the rack A44 continuously moves downward and meshes with the driven gear 53. As the rack A44 continues to descend, it drives the coarse-tooth screw 52 to rotate through the driven gear 53. The coarse-tooth screw 52 then drives the sliding plate 54, which is guided by the guide groove 13, to move backward continuously. When the sliding plate 54 moves backward, it causes the L-shaped support seat 55 to slide backward inside the mounting groove 12. As the L-shaped support seat 55 continues to move backward, the rear end of the pushing beam 57 is first blocked by the inner wall of the mounting groove 12. At this time, the L-shaped support seat 55 continues to move backward. During the subsequent backward movement, the lifting beam 58 is pushed by the non-reverse pushing beam 57, which in turn drives the handcart chassis to rise until the handcart chassis is in contact with the bottom surface of the circuit breaker body. At this time, the hydraulic cylinder 41 is stopped. The mounting holes on the handcart chassis are aligned with the mounting holes at the bottom of the circuit breaker body. When the rack A44 moves upward to reset, the rack A44 drives the driven gear 53 to rotate in the opposite direction, which in turn causes the coarse thread screw 52 to drive the L-shaped bearing seat 55 to move forward and reset along the mounting groove 12 through the sliding plate 54. As the L-shaped bearing seat 55 moves forward continuously, the L-shaped bearing seat 55 drives the lifting beam 58 to move away from the bottom of the handcart chassis and finally reset.

[0035] The specific working process of this invention is as follows: Place the circuit breaker body at the top center of the counterweight tray 410, and place the handcart chassis on the top rear side of the L-shaped bearing seat 55, so that its bottom is in contact with the top of the lifting beam 58. The two electric actuators 22 drive the two moving plates 23 to move closer to each other. The two moving plates 23 drive the two clamping seats 31 to move closer to each other through the two extending arms 25. As the two clamping seats 31 move continuously, the two clamping discs 34 are respectively attached to the upper middle part of both sides of the circuit breaker body and achieve clamping of the circuit breaker body. During the movement of the clamping seat 31, the long gear 37 is driven to move synchronously through the rotating shaft 36. During this process, the long gear 37 always maintains the meshing state with the adjacent rack B47. The hydraulic cylinder 41 drives the lifting plate 42 to move down. When the lifting plate 42 moves down, the counterweight tray 410 moves down synchronously. Since the circuit breaker body is clamped between the two clamping plates 34 at this time, the circuit breaker body does not descend synchronously with the counterweight tray 410. At the same time, due to the limiting effect of the rotating limit groove 33 on the limit rod 35, the circuit breaker body cannot drive the clamping plate 34 to rotate. When the counterweight tray 410 moves down, it drives the two U-shaped seats 45 to move down synchronously. When the U-shaped seats 45 move down, they drive the limiting column 49 to descend inside the lifting limiting groove 48. As the limiting column 49 continues to descend, it moves to the bottom of the inner side of the lifting limiting groove 48. At this time, a clearance space is formed between the counterweight tray 410 and the bottom of the circuit breaker body to avoid the circuit breaker body during counterclockwise rotation. As the lifting plate 42 continues to descend, the counterweight tray 410, under the action of gravity, drives the lifting block 46 to descend through the U-shaped seat 45 and the limiting post 49. When the lifting block 46 descends, it drives the rack B47 to descend synchronously. During the descent of the rack B47, it drives the rotating shaft 36 to rotate counterclockwise through the long gear 37. The two rotating shafts 36 then drive the circuit breaker body to rotate counterclockwise synchronously through the two clamping plates 34 until the circuit breaker body is rotated 90 degrees counterclockwise and its bottom surface faces forward. At this time, the limiting rod 35 rotates from the top of the inner side of the rotating limiting groove 33 to the lowest inner side. Due to the limiting effect of the rotating limiting groove 33 on the limiting rod 35, the circuit breaker body cannot continue to rotate, and the counterweight tray 410 cannot continue to descend. Hydraulic cylinder 41 continues to drive lifting plate 42 to descend. At this time, lifting plate 42 disengages from the bottom of counterweight tray 410 and drives rack A44 to mesh with driven gear 53. At this time, under the action of the weight of counterweight tray 410 itself, the circuit breaker body always maintains the bottom surface facing forward. As rack A44 descends, rack A44 drives coarse-tooth screw 52 to rotate via driven gear 53. Coarse-tooth screw 52 then drives sliding plate 54, guided by guide groove 13, to move backward continuously. When sliding plate 54 moves backward, it drives L-shaped support seat 55 to slide backward inside mounting groove 12. As L-shaped support seat 55 moves backward continuously, the rear end of push beam 57 is first blocked by the inner wall of mounting groove 12. When L-shaped support seat 55 continues to move backward, lifting beam 58 is pushed by push beam 57, which cannot move backward, thereby driving the handcart chassis to rise until the handcart chassis is in contact with the bottom surface of the circuit breaker body. Then, hydraulic cylinder 41 is stopped. At this time, the mounting holes on the handcart chassis are aligned with the mounting holes at the bottom of the circuit breaker body. Use bolts to fix the handcart chassis to the bottom of the circuit breaker body to complete the assembly of the circuit breaker body and the handcart chassis; The hydraulic cylinder 41 drives the lifting plate 42 to move upward and reset. The lifting plate 42 drives the rack A44 to drive the driven gear 53 to rotate in the opposite direction. This causes the coarse thread screw 52 to drive the L-shaped bearing seat 55 to move forward and reset along the mounting groove 12 through the sliding plate 54. As the L-shaped bearing seat 55 moves forward, it drives the lifting beam 58 to move away from the bottom of the handcart chassis and finally reset. As the lifting plate 42 moves upward, it adheres to the bottom of the counterweight tray 410. At this time, as the lifting plate 42 continues to rise, the counterweight tray 410 is pushed upward synchronously under the action of the lifting plate 42. During this process, the circuit breaker body and the handcart chassis also rotate clockwise to a vertical state under the action of gravity. After the top of the counterweight pallet 410 is in contact with the bottom of the handcart, the hydraulic cylinder 41 is stopped, and then the two electric push rods 22 drive the two moving plates 23 to move away from each other, thereby causing the two clamping plates 34 to detach from the sides of the circuit breaker body. At this time, the circuit breaker body with the handcart chassis assembly completed is supported on the top of the counterweight pallet 410. Continue to move the hydraulic cylinder 41 to lift the plate 42 upwards and reset it until the top surface of the counterweight tray 410 is flush with the top surface of the platform 11. At this point, the assembled circuit breaker body can be removed from the top of the counterweight tray 410.
