Description

Technical Field

[0001] The present application relates to the technical field of vacuum circuit breakers, and in particular to a vacuum circuit breaker simulation cabinet inspection and leveling tool. Background Art

[0002] During the production of vacuum circuit breakers, a very important step is to adjust the contact arm and plum blossom contact (moving contact) in the cabinet after the initial assembly of the vacuum circuit breaker is completed, as shown in the attached manual. Figure 1-3 As shown, it includes adjusting the phase spacing of adjacent plum blossom contacts, the upper and lower break distances, and the distance to the ground. This process simulates the vacuum circuit breaker cabinet matching process in advance, which can quickly and effectively discover problems existing in the vacuum circuit breaker cabinet matching and improve the efficiency of vacuum circuit breaker assembly and inspection. If this process cannot be well controlled, it will greatly affect the overall quality of the vacuum circuit breaker.

[0003] like Figure 14 As shown, the adjustment accuracy of the contact arm and the plum blossom contact is relatively high, but the plum blossom contact is a center-hole structure that cooperates with the static contact. Its axis is difficult to find during the adjustment process, resulting in position errors of the measurement points; at the same time, there are also errors in the numerical confirmation during manual measurement, which leads to error accumulation, resulting in large deviations in the positions of multiple contact arms and plum blossom contacts; and there is also an overall deviation of the contact arm and plum blossom contact in the up, down, left and right directions, which will also affect the alignment and plugging with the static contact during cabinet distribution. Summary of the Invention

[0004] In response to the above-mentioned problems, the present application aims to provide a vacuum circuit breaker simulated cabinet inspection and leveling tool, which makes targeted adjustments to each moving contact according to the markings. After the adjustment, it can ensure that the phase spacing, break, grounding, and the overall adjustment of the moving contact are to the designed position, thereby enabling smooth cabinet operation in the later cabinet distribution, thereby improving the cabinet distribution quality and efficiency of the vacuum circuit breaker.

[0005] To achieve the above-mentioned objectives, the technical solution adopted in this application is as follows: a vacuum circuit breaker simulated distribution cabinet inspection and leveling tool, wherein one side of the vacuum circuit breaker has multiple contact arms and moving contacts, and the bottom is provided with a chassis vehicle, and one side of the chassis vehicle is provided with a driving beam, and telescopic locking pins are provided at both ends of the driving beam, characterized in that:

[0006] The inspection and leveling tooling includes a transfer trolley for receiving and transferring the vacuum circuit breaker, and an adjustment platform detachably connected to the transfer trolley and for transferring the vacuum circuit breaker. A static contact corresponding to each moving contact is arranged in a standard position on the adjustment platform.

[0007] Preferably, one end of the transfer trolley is provided with a positioning pin that is plugged into the adjusting platform, and a hook rod that is detachably locked with the adjusting platform, and a first guide rail that guides the chassis vehicle to move is provided on the top surface of the transfer trolley.

[0008] Preferably, one side of the adjustment platform has a pin hole and a trolley lock hole corresponding to the positioning pin and the hook rod, and a second guide rail linearly connected to the first guide rail is provided on the surface of the adjustment platform, and a crossbeam lock hole corresponding to the locking pin is provided on the outer side of the second guide rail.

[0009] Preferably, the static contact includes a first static contact with a columnar structure, and a second static contact detachably sleeved on the first static contact.

[0010] The beneficial effects of the present application are: the inspection and leveling tooling realizes the position inspection and guidance of the moving contact through the static contact in the standard position, and can obtain the deviation status of each moving contact and mark it. After the inspection is completed, each moving contact is adjusted in a targeted manner according to the mark. After the adjustment, the phase spacing, break, grounding, and the overall adjustment of the moving contact to the designed position can be ensured, so that smooth cabinet matching operation can be achieved during the later cabinet matching, avoiding the deviation between the moving contact and the static contact in the cabinet body, resulting in misalignment, skewed contact and impact damage, thereby improving the cabinet matching quality and efficiency of the vacuum circuit breaker.

[0028] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Refer to the attached Figures 1 to 14 A vacuum circuit breaker simulated cabinet inspection and leveling tool is shown, Figure 1-3 As shown, the vacuum circuit breaker 1 has a plurality of contact arms 11 and moving contacts 12 on one side, and a chassis 13 is provided at the bottom. A driving beam 131 is provided on one side of the chassis 13, and telescopic locking pins 132 are provided at both ends of the driving beam 131. During the cabinet distribution process, the vacuum circuit breaker 1 is placed on the cabinet distribution platform through the chassis 13, and the driving beam 131 and the cabinet body are plugged and positioned by the locking pins 132 (telescopic structure) on both sides. Then, a hand crank 5 is installed on the driving beam 131, which rotates the driving screw (not shown in the figure) in the chassis 13, so that the chassis 13 except the driving beam 131 and the vacuum circuit breaker 1 as a whole move toward the static contact in the cabinet body, thereby realizing the plugging of the moving contact 12 and the static contact.

[0030] In order to adjust the phase spacing, break, grounding and overall moving contact 12 of the moving contact 12 to the designed position before the cabinet is matched, so as to solve the error accumulation and difficulty in adjustment during the current manual adjustment, the present application is provided with an inspection and leveling tool, such as Figure 4-6 As shown, it includes a transfer trolley 2 for receiving and transferring the vacuum circuit breaker 1, and an adjustment platform 3 that is detachably connected to the transfer trolley 2 and transfers the vacuum circuit breaker 1. A static contact 4 corresponding to each moving contact 12 is arranged in a standard position on the adjustment platform 3. Among them, the transfer trolley 2 is used to transfer the assembled vacuum circuit breaker 1 and the unadjusted position spacing of the contact arm 11 and the moving contact 12 to one side of the adjustment platform 3, and transfer the vacuum circuit breaker 1 to the adjustment platform 3, and then the moving contact 12 is plugged into the static contact 4 in the standard position set on the adjustment platform 3. The position of the moving contact 12 is inspected and guided by the static contact 4 in the standard position, and the deviation state of each moving contact 12 can be obtained and marked. After the inspection is completed, each moving contact 12 is adjusted in a targeted manner according to the mark. After the adjustment, the phase spacing, break, grounding, and the overall adjustment of the moving contact 12 to the designed position can be ensured, so that smooth cabinet matching operation can be achieved in the later cabinet matching, avoiding deviations between the moving contact 12 and the static contact in the cabinet body, resulting in misalignment, skewed contact and impact damage, thereby improving the cabinet matching quality and efficiency of the vacuum circuit breaker 1.

[0031] Specifically, such as Figure 4 As shown, one end of the transfer trolley 2 is provided with a positioning pin 21 plugged into the adjustment platform 3, and a hook rod 22 that is detachably locked with the adjustment platform 3. The hook rod 22 is a horizontal hinged structure, and a first guide rail 23 is provided on the top surface of the transfer trolley 2 to guide the chassis 13. Figure 7-9 As shown, after the assembled vacuum circuit breaker 1 to be adjusted in phase spacing is hoisted and placed on the transfer trolley 2 and transferred to one side of the adjustment platform 3, the positioning pin 21 is inserted into the adjustment platform 3 to realize the positioning of the transfer trolley 2, and then the hook rod 22 is rotated to hook it on the adjustment platform 3 to realize the connection and positioning of the transfer trolley 2 and the adjustment platform 3, and then the vacuum circuit breaker 1 is driven, and the chassis 13 rolls on the first guide rail 23 to transfer the vacuum circuit breaker 1 to the adjustment platform 3.

[0032] Specifically, such as Figure 5-6 As shown, one side of the adjustment platform 3 has a pin hole 3a and a trolley lock hole 3b corresponding to the positioning pin 21 and the hook rod 22, as shown in FIG. Figure 8 As shown, the positioning pin 21 of the above-mentioned transfer trolley 2 is inserted into the pin hole 3a on the side of the adjustment platform 3, and the hook rod 22 is inserted into the trolley lock hole 3b on the side. The hook rod 22 is rotated so that the hook rod 22 is hooked on the inner side of the trolley lock hole 3b of the adjustment platform 3, thereby positioning and pulling the transfer trolley 2 and the adjustment platform 3. Figure 8 Status shown.

[0033] A second guide rail 31 is provided on the surface of the adjustment platform 3, which is in straight line connection with the first guide rail 23. A crossbeam lock hole 3c corresponding to the locking pin 132 is provided on the outer side of the second guide rail 31. After the transfer trolley 2 is positioned and coupled to the adjustment platform 3, the vacuum circuit breaker 1 is driven to slide from the first guide rail 23 to the second guide rail 31 of the adjustment platform 3. The locking pin 132 (telescopic) of the driving crossbeam 131 is inserted into the crossbeam lock hole 3c of the second guide rail 31 to position the driving crossbeam 131 on the adjustment platform 3. The transfer trolley 2 is then removed, and a hand crank is connected to the outer side of the driving crossbeam 131 to drive the chassis 13 except the driving crossbeam 131 and the vacuum circuit breaker 1 as a whole to move toward the static contact in the cabinet, thereby realizing the plugging, inspection and marking operations of the moving contact 12 and the static contact 4 on the adjustment platform 3.

[0034] In order to adapt to the inspection and leveling operation of the moving contact 12 and the static contact 4 of different specifications, Figure 12 As shown, the static contact 4 includes a first static contact 41 with a columnar structure, and a second static contact 42 that is detachably mounted on the first static contact 41. When the first static contact 41 is in use, the second static contact 42 is removed; when the second static contact 42 is in use, it can be mounted on the first static contact 41 for use.

[0035] Since there is a plug-in gap between the moving contact 12 and the static contact 4 when plugging, Figure 13 As shown, after plugging, the dynamic and static heads 12 will still pass through the plugging gap and affect their position accuracy. Therefore, in order to solve this problem, as shown in FIG. Figure 14 As shown, preferably, the first static contact 41 and the second static contact 42 both have a tapered surface segment 4a, and the inner diameter of the movable contact 12 is between the outer diameter of the small end and the outer diameter of the large end of the tapered surface segment 4a. Therefore, when plugged in, the inner port of the movable and static heads 12 will circumferentially contact the tapered surface segment 4a, thereby eliminating the plugging gap between the movable contact 12 and the static contact 4, further improving the guiding accuracy of the movable and static heads 12, thereby improving the subsequent cabinet quality and the conduction quality during use. At the same time, the small end of the tapered surface segment 4a also facilitates the quick and smooth insertion of the unadjusted and deflected movable contact 12 onto the static contact 4.

[0036] The principle of this application is: after the assembled vacuum circuit breaker 1 to be adjusted in phase spacing is hoisted and placed on the transfer trolley 2 and transferred to one side of the adjustment platform 3, the positioning pin 21 of the transfer trolley 2 is inserted into the pin hole 3a on the side of the adjustment platform 3, and the hook rod 22 is inserted into the trolley lock hole 3b on the side, and the hook rod 22 is rotated so that the hook rod 22 is hooked on the inner side of the trolley lock hole 3b of the adjustment platform 3, thereby realizing the positioning and connection of the transfer trolley 2 and the adjustment platform 3.

[0037] Then drive the vacuum circuit breaker 1 to slide from the first guide rail 23 to the second guide rail 31 of the adjustment platform 3, and insert the locking pin 132 of the driving beam 131 into the beam lock hole 3c of the second guide rail 31 to position the driving beam 131 on the adjustment platform 3, remove the transfer trolley 2, and then connect the hand crank to the outside of the driving beam 131 to drive the chassis 13 except the driving beam 131. The part and the vacuum circuit breaker 1 as a whole are moved toward the static contact in the cabinet, and the moving contact 12 is gradually inserted into the static contact 4. The position of the moving contact 12 is inspected and marked. After the vacuum circuit breaker 1 is removed, the position of the moving contact 12 is adjusted and locked, and then a smooth cabinet distribution operation can be achieved.

[0038] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
