Description

Technical Field

[0001] This application relates to the field of circuit breaker manufacturing, and in particular to an automatic withstand voltage testing device for circuit breakers. Background Technology

[0002] To ensure that circuit breakers manufactured or used during maintenance can be used normally, they need to be subjected to withstand voltage testing (i.e., withstand voltage test).

[0003] In existing circuit breaker withstand voltage testing processes, the contacts of the circuit breaker under test need to be externally wired. There are corresponding existing devices that use motors or other drive mechanisms to move the wiring mechanism, allowing it to connect to the circuit breaker contacts. However, in automatic wiring equipment testing, the product under test needs to be manually moved and sampled before testing, and then unsampled and moved after testing. Because wiring mechanisms in the same moving position are usually mounted on the same moving carrier in automatic wiring equipment, the positions and distances between adjacent wiring mechanisms in the same moving position are fixed, and the moving carriers have certain travel limitations.

[0004] Therefore, operators need to arrange the circuit breakers at regular intervals within the movable travel range of the wiring mechanism. If the product under test is not accurately positioned within the movable travel range of the wiring mechanism, the wiring mechanism will have difficulty accurately contacting the contacts of the product under test during subsequent wiring operations.

[0005] Because the equipment handles a large volume of product testing, requiring numerous precise sample placement and removal operations, the existing sample placement and removal methods are labor-intensive and inefficient. Therefore, improving the efficiency of this process and saving manpower is a key challenge for this industry. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The technical features designed in the different implementations of this application described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be noted that all terms used in this application (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains, and should not be construed as limiting this application. It should be further understood that the terms used in this application should be understood to have the same meaning as those in the context of this specification and the relevant field, and should not be interpreted in an idealized or overly formal sense, except as expressly defined herein. The terms "first," "second," etc., in the specification, claims, and accompanying drawings of the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0038] This application provides, as follows: Figure 1-9 The circuit breaker withstand voltage testing equipment shown in the embodiment has the following technical solution:

[0039] This application provides a circuit breaker withstand voltage testing device, which includes a trolley lifting device 10, a frame 20, and a movable wiring device mounted on the frame 20. The trolley lifting device 10 includes a support platform 100 located below the frame 20 and a transfer cart 200. Several products 220 can be placed on the transfer cart 200. A pair of limiting track baffles 130 are provided on the platform 110 of the support platform 100. The installation space formed by the distance between the two limiting track baffles 130 is used to place the transfer cart 200 and to limit the left and right movement of the transfer cart 200. A blocking module 120 is provided in the area formed between the tail ends of the two limiting track baffles 130. The blocking module 120 includes a first position adjustment component and a blocking block 121 for blocking the transfer cart 200 from moving backward. The blocking block 121 is mounted on the platform 110 through the first position adjustment component so that the front and rear positions of the blocking block 121 can be adjusted.

[0040] Specifically, such as Figure 1-9As shown, before the product under test 220 is sampled, it is loaded onto the transfer cart 200. Then, the transfer cart 200 carrying the product is pushed onto the platform 110. At this point, the transfer cart 200 is pushed between the two limiting track baffles 130 on the platform 110. The two limiting track baffles 130 restrict the left and right movement of the transfer cart 200, and the blocking block 121 of the blocking module 120 blocks the forward movement of the transfer cart 200, ensuring that the transfer cart 200 is accurately positioned within the movable travel range of the mobile wiring device. This ensures that the product under test 220 is accurately positioned within the movable travel range of the mobile wiring device, thereby ensuring smooth wiring between the mobile wiring device and the product under test 220 and the reliability of the wiring. Simultaneously, this effectively reduces the manual labor costs of product 220 transfer and positioning, improving the overall efficiency of the product under test transfer, positioning, and testing process.

[0041] Then, the mobile wiring device moves within its travel range and connects to product 220. Finally, after the wiring withstand voltage test is completed, the transfer cart 200 is moved to the tabletop 110 to unload the sample, thus repeating the above sample loading process.

[0042] The design of the blocking block 121 allows for position adjustment via the first position adjustment component, enabling the device to accurately position itself to accommodate transfer carts 200 of different models and lengths. Even when using different models of transfer carts 200, or products 220 of different models, sizes, or arrangements, the device can still accurately position the product under test 220 within the movable travel range of the mobile wiring device. This enhances the device's flexibility and versatility.

[0043] When transferring and loading the existing product 220, a transfer trolley is usually needed to move the product 220 to the wiring equipment. Since the transfer trolley lacks corresponding structural and insulation design, to achieve insulation during testing, the product 220 needs to be unloaded from the transfer trolley and then arranged within the movable travel range of the mobile wiring device before testing, or an insulating pad needs to be placed on the transfer trolley before testing. This process is significantly more cumbersome and complex, resulting in high manpower consumption. In this embodiment, the trolley lifting device 10 adopts an insulated design, requiring minimal operator intervention; simply pushing the transfer trolley 200 into position is sufficient. Specifically, for the design of insulating the product 220 from external components such as the ground and frame 20 during testing, the following implementation schemes are available: Optionally, as in this embodiment: the trolley lifting device 10 further includes a lifting drive mechanism 300 mounted on the frame 20; the output end of the lifting drive mechanism 300 is connected to the support platform 100, used to drive the support platform 100 to move up and down. Alternatively, the transfer vehicle 200 includes a vehicle body 210, a mounting frame 240, and a product 220; the mounting frame 240 is mounted on the vehicle body 210, the product 220 is mounted on the mounting frame 240, and the mounting frame 240 is an insulated mounting frame; or alternatively, the support platform 100 is an insulated support platform 100.

[0044] When the support platform 100 uses a lifting design, the equipment operation process is as follows: The lifting drive mechanism 300 drives the support platform 100 to descend, so that the platform surface 110 of the support platform 100 is on the ground. Then, the transfer cart 200 carrying the product 220 is pushed onto the platform surface 110. Afterward, the lifting drive mechanism 300 drives the support platform 100 to rise (the entire support platform 100 does not contact the ground, forming insulation), and the moving wiring device moves within its travel range and connects to the product 220. Finally, after the wiring withstand voltage test is completed, the support platform 100 descends, so that the platform surface 110 is on the ground, and the transfer cart 200 is moved onto the platform surface 110 for sample unloading, thus repeating the above sample loading process.

[0045] When the support platform 100 does not use a lifting design, the equipment operation process is as follows: The support platform 100 is always located on the ground, so the transfer cart 200 carrying the product is directly pushed to the platform 110. The moving wiring device moves within its travel range and connects to the product 220. At this time, since the mounting bracket 240 or the support platform 100 is insulated, insulation can be formed. Finally, after testing, the transfer cart 200 is moved to the platform 110 for sample unloading.

[0046] Optionally, the limiting track baffle 130 is detachably mounted on the platform 110 via the second position adjustment component 140, so that the limiting track baffle 130 can move left and right.

[0047] The design of the second position adjustment component 140 allows the positions of the two limiting track baffles 130 to be adjusted, enabling the equipment to accurately position the transfer carts 200 of different widths and sizes. Even when using different models of transfer carts 200, different models, different sizes, or different arrangements of products 220, the product to be tested 220 can still be accurately positioned within the movable travel range of the mobile wiring device. This enhances the flexibility and versatility of the equipment.

[0048] The specific structural design of the first position adjustment component and the second position adjustment component 140 is as follows:

[0049] Optionally, the first position adjustment component includes a clamping mechanism 122 fixedly connected to the table 110, and the output end of the clamping mechanism 122 is connected to the blocking block 121 to drive the blocking block 121 to hook the transfer cart 200 to move.

[0050] Optionally, the second position adjustment component 140 includes a sliding rail 141, a connecting block 142, and a second linear drive mechanism 143 fixedly connected to the platform 110; the sliding rail 141 is disposed on the platform 110, and its travel direction is the left and right movement direction; the output end of the second linear drive mechanism 143 is connected to the limiting rail baffle 130, and the limiting rail baffle 130 is provided with the connecting block 142, the connecting block 142 being detachably and slidably connected to the sliding rail 141, so that the second linear drive mechanism 143 drives the limiting rail baffle 130 to move left and right.

[0051] It should be noted that, according to the design concept of this application, the specific structures of the first position adjustment component and the second position adjustment component 140 can respectively satisfy the above-mentioned position adjustment function (the first position adjustment component drives the blocking block 121 to hook the transfer vehicle 200 to move, and the second position adjustment component 140 enables the limiting track baffle 130 to move left and right). The specific structural design of the first position adjustment component and the second position adjustment component 140 includes, but is not limited to, the scheme of this embodiment.

[0052] Optionally, the first position adjustment assembly and the second position adjustment assembly 140 are electrically connected to the control system. The control system controls the operating state of the clamping mechanism 122 of the first position adjustment assembly and the operating state of the second linear drive mechanism 143 of the second position adjustment assembly 140, thereby adjusting the position of the blocking block 121 and the two limiting track baffles 130.

[0053] Optionally, the blocking module 120 includes a position sensor 123, which is used to sense the position of the transfer vehicle 200 within the installation space. The position sensor 123 and the clamping mechanism 122 are electrically connected to the control system, so that the position sensor 123 can sense the position of the transfer vehicle and transmit the signal to the control system for processing. The control system can adjust the blocking block 121 to limit the transfer vehicle 200 by controlling the operation of the clamping mechanism 122, and can also process the sensor signal to determine the position of the transfer vehicle 200 and whether it has moved into place.

[0054] Optionally, the blocking block 121 is provided with an elastic buffer pad. The elastic buffer pad is designed to cushion the impact between the blocking block 121 and the transfer vehicle 200.

[0055] Optionally, the front ends of the two limiting track baffles 130 are bent and extended to the left and right sides respectively, so that the front ends of the two limiting track baffles 130 form a trumpet-shaped opening 131.

[0056] The design of the trumpet-shaped opening 131 facilitates the smooth advancement of the transfer vehicle 200 between the two limiting track baffles 130.

[0057] When the support platform 100 adopts a lifting design, optionally, the support platform 100 includes a horizontally arranged platform 110 and two connecting brackets 150 respectively connected to the left and right sides of the platform 110; the brackets 150 extend upward and bend, and the bottom of their bent surfaces are connected to a flat plate 170 through a first insulating column 160; the bottom of the frame 20 is provided with a lifting platform 21, so that after the support platform 100 moves down, the flat plate 170 moves to abut against the lifting platform 21, and the lifting platform 21 is used to support the flat plate 170. Optionally, the output end of the lifting drive mechanism 300 is connected to the bracket 150 to drive the bracket 150 to move up and down, thereby driving the platform 110 to move up and down. Optionally, the bracket 150 is composed of interconnected vertical plates and horizontal straight plates, so that the support platform 100 forms an inverted "U" shaped structure.

[0058] Through the above design, when the platform 110 is lowered to the ground, the lifting platform 21 can support the plate 170, thereby supporting the entire bearing platform 100 and improving the structural stability of the equipment. Furthermore, the plate 170 and the support 150 are connected by a first insulating column 160, ensuring that the bearing platform 100 is insulated from the ground when the platform 110 is lowered to the ground.

[0059] Optionally, the movable wiring device is fixedly connected to the frame 20 via a second insulating post 60.

[0060] Optionally, the product 220 is mounted on the mounting bracket 240, and the mounting bracket 240 is provided with the flipping mechanism 230. Optionally, the flipping mechanism 230 is electrically connected to the control system.

[0061] It should be noted that the tilting mechanism 230 is in its original position. If the mounting bracket 240 is made of insulating material, the lifting platform 21 can be omitted, and the limiting track baffle 130 and the second position adjustment assembly 140 can be directly placed on the ground for testing.

[0062] Optionally, the movable wiring device includes a vertical movable wiring device 30 and a lateral movable wiring device 40. The vertical movable wiring device 30 includes a first wiring mechanism 31 for wiring with the contacts of the product 220 and a first orientation adjustment mechanism 32. The first orientation adjustment mechanism 32 drives the first wiring mechanism 31 to move up and down, so that the first wiring mechanism 31 is connected to the contacts of the product 220. The lateral movable wiring device 40 includes a second wiring mechanism 41 for wiring with the contacts of the product 220 and a second orientation adjustment mechanism 42. The second orientation adjustment mechanism 42 is a combination of two-way motion mechanisms, which drives the second wiring mechanism 41 to move up and down and left and right, so that the second wiring mechanism 41 is connected to the contacts of the product 220. Optionally, the first orientation adjustment mechanism 32 and the second orientation adjustment mechanism 42 are electrically connected to the control system.

[0063] like Figure 1 As shown, to accommodate the product under test model 220 shown in this embodiment (using the ZW32 outdoor circuit breaker as an example product), the movable wiring device in this embodiment includes a vertical movable wiring device 30 and a lateral movable wiring device 40. According to the concept of this application, the number and movement direction of the movable wiring devices can be adjusted for applicability according to the model of the product 220 to be tested, including but not limited to the scheme of this embodiment.

[0064] Optionally, the front end of the platform 110 is provided with an inclined slope. The inclined slope design facilitates the smooth pushing of the transfer vehicle 200 onto the platform 110.

[0065] It should be noted that:

[0066] The specific structural design of the wiring mechanism in the mobile wiring device in this application embodiment can adopt existing clamping type wiring mechanism or contact type wiring mechanism, which are prior art and will not be described in detail here.

[0067] This embodiment can control the operating status of the lifting drive mechanism 300, clamping mechanism 122, second linear drive mechanism 143, first orientation adjustment mechanism 32, and second orientation adjustment mechanism 42 through a control system. By receiving and processing information from the position sensor 123, the control system can achieve position signal reception and automated orientation adjustment of components such as the support platform 100, blocking module 120, limiting track baffle 130, first wiring mechanism 31, and second wiring mechanism 41. The control system is existing technology; it has a programmable memory for storing programs and executing user-oriented instructions such as logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of machinery or production processes through digital or analog input / output. This is also existing technology and will not be described in detail here. The working principle of the above-mentioned drive components, sensors, and control system cooperating to perform signal reception, information processing, and feedback is also existing technology and will not be described in detail here.

[0068] Optionally, the driving components of the lifting drive mechanism 300, clamping mechanism 122, second linear drive mechanism 143, first orientation adjustment mechanism 32, and second orientation adjustment mechanism 42 may be reciprocating linear drive mechanisms, including but not limited to motors, cylinders, etc.
