Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tooling, and in particular to a tooling for assisting the assembly of a vacuum interrupter. Background Art

[0002] The vacuum interrupter, also known as the vacuum switch tube, is the core component of the medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off from the power supply through the excellent insulation of the vacuum inside the tube, so as to avoid accidents and unexpected events. The vacuum interrupter is mainly used in the power transmission and distribution control system, and is also used in the power distribution systems of metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communication, industrial high-frequency heating, etc.

[0003] The vacuum arc extinguishing chamber includes a contact seat, a porcelain shell, a moving conductive rod and an elastic member, wherein one end of the moving conductive rod is sealed in the porcelain shell, the other end of the moving conductive rod is detachably connected to the contact seat, and the elastic member is compressed in the contact seat. At present, fasteners are usually used to realize the detachable connection between the moving conductive rod and the contact seat, and guide members are used to realize the compression of the elastic member. Specifically, when the moving conductive rod and the contact seat are detachably installed, workers are required to clamp the moving conductive rod with calipers, and the fasteners are then screwed into the contact seat and the moving conductive rod to prevent the moving conductive rod from rotating during installation. When compressing the elastic member, the guide member is placed above the elastic member, and then the worker is required to pass the connecting rod through the pin hole of the guide member, and then press the connecting rod by hand until the elastic member is compressed to a preset position to realize the compression of the elastic member.

[0004] During the above installation process, workers are required to hold the dynamic calipers to fix the dynamic conductive rod, which is inefficient and has high labor costs. Workers are also required to manually press the connecting rod to compress the spring, which makes it difficult to ensure that each downward pressure is a vertical downward force. When the force is offset, it is easy to generate radial force on the dynamic conductive rod, thereby causing irreversible damage to the porcelain shell. Summary of the invention

[0037] See also Figure 1 As shown, Figure 1 The schematic diagram of the structure of the vacuum interrupter 20 provided in the present application. In the related art, the vacuum interrupter 20 includes a contact seat 21, a porcelain shell 22, a movable conductive rod 23 and an elastic member 24, wherein one end of the movable conductive rod 23 is sealed and arranged in the porcelain shell 22, the other end of the movable conductive rod 23 is detachably connected to the contact seat 21, and the elastic member 24 is compressed in the contact seat 21. During the specific installation, the fastener 25 is usually used to realize the detachable connection between the movable conductive rod 23 and the contact seat 21, and the guide member 26 is used to realize the compression of the elastic member 24. The fastener 25 can be a fastening element such as a bolt or a screw.

[0038] Specifically, when the movable conductive rod 23 and the contact seat 21 are detachably installed, a worker needs to clamp the movable conductive rod 23 with a caliper, and then screw the fastener 25 into the contact seat 21 and the movable conductive rod 23 to prevent the movable conductive rod 23 from rotating during installation. When compressing the elastic member 24, the guide member 26 is placed above the spring, and then the worker needs to pass the connecting rod through the pin hole 27 of the guide member 26, and then manually press the connecting rod until the elastic member 24 is compressed to a preset position to achieve compression of the elastic member 24.

[0039] However, during the above installation process, workers are required to hold the dynamic calipers to fix the dynamic conductive rod 23, which is inefficient and has high labor costs. Workers are also required to manually press the connecting rod to compress the spring, which makes it difficult to ensure that each downward pressure is a vertical downward force. When the force is offset, it is easy to generate radial force on the dynamic conductive rod 23, thereby causing irreversible damage to the ceramic shell 22.

[0040] Based on this, see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of a structure for assisting the assembly of a vacuum interrupter 20 provided in an embodiment of the present application. Figure 3 for Figure 2 The enlarged structural diagram at A in the middle. The tooling 10 for assisting the assembly of the vacuum interrupter 20 provided in one embodiment of the present application includes a transport vehicle 100, a support frame 200 and a lifting drive mechanism 300, wherein the transport vehicle 100 has a bearing surface 111, and the bearing surface 111 is used to bear the porcelain shell 22 in the vacuum interrupter 20, and a moving conductive rod 23 is provided on the porcelain shell 22, and a contact seat 21 is provided at the top of the moving conductive rod 23, and an elastic member 24 is provided in the contact seat 21 to abut against each other. In the specific setting, the transport vehicle 100 includes a transport seat 110 and rollers 120 installed on the transport seat 110, and the number of rollers 120 is multiple, and the multiple rollers 120 are arranged at intervals on the transport seat 110. Specifically, the present application preferably has four rollers 120, and the four rollers 120 are arranged at the four corners of the transport seat 110. During specific use, the ceramic shell 22 and the movable conductive rod 23 disposed on the bearing surface 111 of the transport seat 110 are transported to a set position by the roller 120 .

[0041] The support frame 200 is provided with a first clamping groove 211 adapted to the outer circumference of the movable conductive rod 23. The first clamping groove 211 is used to clamp the movable conductive rod 23. When in use, the transport vehicle 100 transports the movable conductive rod 23 to the first clamping groove 211 for clamping, that is, the movable conductive rod 23 is fixed to the support frame 200 through the first clamping groove 211. The top of the movable conductive rod 23 is provided with a contact seat 21. At this time, the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23. The first clamping groove 211 prevents the movable conductive rod 23 from rotating, thereby eliminating the traditional method of fixing the movable conductive rod 23 by workers holding pliers, improving work efficiency and reducing labor costs.

[0042] The fixed end of the lifting drive mechanism 300 is arranged on the support frame 200, and the output end of the lifting drive mechanism 300 is arranged vertically, and the output end of the lifting drive mechanism 300 is used to abut against the elastic member 24 in the contact seat 21. Through the above arrangement, the lifting drive mechanism 300 is used to apply a force to the elastic member 24 to achieve the deformation of the elastic member 24, ensuring that the force is constant and controllable, and the output end is arranged vertically so that the force applied to the elastic member 24 is vertically downward, avoiding the situation where the force deviation generates a radial force on the movable conductive rod 23, thereby causing damage to the porcelain shell 22.

[0043] In order to better clamp the moving conductive rod 23 by the first clamping groove 211, a preferred embodiment is that the moving conductive rod 23 has a first end 28 that exceeds the porcelain shell 22, and the first end 28 is provided with an annular groove along its own circumference to form a clamping neck 29, and the first clamping groove 211 is used to clamp with the clamping neck 29. It should be noted that in order to ensure the strength of the clamping neck 29, it is not easy to open an annular groove that is too deep, so that the contact area between the groove wall of the first clamping groove 211 and the groove wall of the annular groove is limited, and then the clamping force of the first clamping groove 211 on the moving conductive rod 23 is limited, and it is not easy to compress the elastic member 24 with too large elastic force. Based on this, in order to solve the above problem, the support frame 200 is also provided with a second clamping groove 212 spaced apart from the first clamping groove 211, the second clamping groove 212 is adapted to the outer periphery of the first end 28, and the second clamping groove 212 is used to clamp with the first end 28.

[0044] Through the above arrangement, when in actual use, the transport vehicle 100 first transports the movable conductive rod 23 to the first slot 211, so that the first slot 211 is engaged with the engaging neck 29; then the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23; thereafter, the movable conductive rod 23 is transported to the second slot 212 by the transport vehicle 100, so that the second slot 212 is engaged with the first end 28 of the movable conductive rod 23, thereby increasing the contact area between the second slot 212 and the first end 28, and fixing the movable conductive rod 23 more firmly, facilitating the subsequent compression of the elastic member 24.

[0045] In order to facilitate the transport vehicle 100 to deliver the moving conductive rod 23 to the first groove and the second groove, specifically, the support frame 200 includes a load-bearing plate 210 and at least one column 220. In a specific setting, the number of columns 220 can be 2, 4, 6 or more. The load-bearing plate 210 is connected to the column 220. The height of the column 220 is the sum of the height of the transport vehicle 100 and the height of the ceramic shell 22. An accommodating space 230 is formed between the load-bearing plate 210 and the column 220. A first slot 211 is provided on the side of the load-bearing plate 210 to facilitate the ceramic shell 22 on the transport vehicle 100 and at least part of the transport vehicle 100 to enter the accommodating space 230 when the transport vehicle 100 is transported. The clamping neck 29 at the top of the ceramic shell 22 is exactly at the same height as the first slot 211 for clamping.

[0046] The side of the carrier plate 210 in one embodiment of the present application is also provided with a second slot 212, and a clamping pad 240 is provided on the top of the carrier plate 210 along the circumference of the second slot 212, and the clamping pad 240 is used to clamp the first end 28. In the specific setting, the second slot 212 is preferably a U-shaped slot, and the clamping pad 240 is also designed to be U-shaped accordingly. It should be noted that the shape of the second slot 212 is not limited to the above-mentioned U-shape, and can be any geometric shape such as an ellipse or rectangle with one end open, and the shape of the clamping pad 240 can also be any geometric shape with one end open.

[0047] In order for the vacuum interrupter 20 to better bear the downward force applied by the lifting drive mechanism 300, more specifically, when the second clamping groove 212 is clamped with the first end 28, the bottom end of the contact seat 21 close to the moving conductive rod 23 abuts against the top end of the bearing plate 210. In a specific setting, the bottom end of the contact seat 21 close to the moving conductive rod 23 abuts against the top end of the clamping pad 240. In order to more conveniently achieve the bottom end of the contact seat 21 abutting against the top end of the clamping pad 240, a limiting groove is further provided on the bearing surface 111 of the transport seat 110, and the porcelain shell 22 is arranged in the limiting groove to reduce the height of the porcelain shell 22 beyond the transport seat 110, so that the first end 28 is compatible with the second clamping groove 212 and the clamping pad 240.

[0048] In order to fix the lifting drive mechanism 300 more conveniently and ensure that the output end of the lifting drive mechanism 300 can be aligned with the elastic member 24, specifically, the support frame 200 further includes a positioning frame 250, the positioning frame 250 is arranged on the side of the bearing plate 210 away from the column 220, the fixed end of the lifting drive mechanism 300 is arranged on the positioning frame 250, and the output end of the lifting drive mechanism 300 passes through the positioning frame 250 and is arranged opposite to the second card slot 212 located in the positioning frame 250. In the specific setting, the positioning frame 250 includes a top plate 251 and a side wall 252 arranged on the top plate 251, the side wall 252 and the top plate 251 form a receiving cavity 253, the fixed end of the lifting drive mechanism 300 is arranged on the top plate 251, and the output end of the lifting drive mechanism 300 passes through the top plate 251 and is located in the receiving cavity 253. A notch is formed on the side wall 252 and communicates with the accommodating cavity 253 , so that the contact seat 21 can be located in the accommodating cavity 253 through the notch after the second clamping groove 212 is clamped with the first end 28 .

[0049] Through the above arrangement, when in actual use, the transport vehicle 100 first transports the porcelain shell 22 and the movable conductive rod 23 arranged on the porcelain shell 22 to the first clamping groove 211, so that the first clamping groove 211 is clamped with the clamping neck 29; then the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23; thereafter, the porcelain shell 22 is arranged in the limit groove in the transport vehicle 100; and then the movable conductive rod 23 on the porcelain shell 22 is transported to the second clamping groove 212 by the transport vehicle 100, so that the second clamping groove 212 is clamped with the first end portion 28 of the movable conductive rod 23; and then the lifting drive mechanism 300 is started, and the output end of the lifting drive mechanism 300 is lowered to compress the elastic member 24 in the contact seat, thereby compressing the elastic member 24.

[0050] It should be noted that the elastic member 24 in the contact seat 21 needs to be kept in a compressed state. In order to fix the compressed state of the elastic member 24 at this time, the support frame 200 further includes an abutment plate 260, which is arranged on the bearing plate 210 and is located in the positioning frame 250. In specific operation, the tooling 10 for assisting the assembly of the vacuum interrupter 20 also includes a positioning piece 400. The elastic member 24 is a spring. The positioning piece 400 passes through the gap between the contact seat 21 and the spring in the compressed state and then abuts against the abutment plate 260 to ensure that the state of the spring at this time remains unchanged. In specific settings, the contact seat 21 is provided with a positioning through hole that penetrates its own thickness so that the positioning piece 400 can pass through.

[0051] Through the above arrangement, during specific operation, after the lifting drive mechanism 300 has compressed the elastic member 24, the positioning piece 400 is inserted into the gap of the spring through the positioning through hole to fix the position of the spring; then the lifting drive mechanism 300 rises, allowing the output end of the lifting drive mechanism 300 to exit the contact seat 21; then the guide member 26 is installed above the spring, and the guide member 26 in this position is fixed by the fixing pin on the guide member 26; then the positioning piece 400 is taken out to complete the installation.

[0052] In order to ensure the stability of the load-bearing plate 210, further, the number of the columns 220 is at least four, and the four columns 220 are arranged at the four corners of the load-bearing plate 210. In the specific setting, the load-bearing plate 210 is preferably a rectangular structure, and four columns 220 are arranged correspondingly at the four corners of the load-bearing plate 210. It should be noted that the load-bearing plate 210 is not limited to the above-mentioned rectangular structure, and the shape of the load-bearing plate 210 can be any geometric figure such as a circle, an ellipse, a diamond, a polygon, etc. The specific number of the columns 220 can be 4, 5 or more, and a plurality of columns 220 can be distributed in the circumferential direction of the load-bearing plate 210 at intervals.

[0053] In order to strengthen the strength of the support frame 200, further, a first reinforcing rib 270 is provided between two adjacent columns 220. In a specific configuration, a second reinforcing rib 280 is further provided between the two first reinforcing ribs 270. More specifically, the second reinforcing rib 280 is provided at the middle position of the first reinforcing rib 270.

[0054] In order to design the lifting drive mechanism 300 more conveniently, a preferred embodiment is that the lifting drive mechanism 300 includes a lifting drive member 310 and a pressure rod 320 connected to the output end of the lifting drive member 310, the pressure rod 320 is vertically arranged, and one end of the pressure rod 320 vertically away from the lifting drive member 310 is used to abut against the elastic member 24 in the contact seat 21. Through the above arrangement, the lifting drive member 310 acts on the elastic member 24 through the pressure rod 320, ensuring that the force applied to the elastic member 24 is constant, and the vertical arrangement of the pressure rod 320 ensures that the force applied to the elastic member 24 is vertically downward, avoiding the situation where the force deviation generates a radial force on the moving conductive rod 23, thereby causing damage to the porcelain shell 22.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
