Description

Technical Field

[0001] The utility model relates to the technical field of gas relay detection, and particularly relates to an operation detection system for a gas relay. Background Art

[0002] A gas relay (also known as a gas actuated relay) is an important device for non-electric quantity protection of oil-immersed transformers. It is installed in the pipeline between the conservator and the oil tank of the transformer. When a discharge fault occurs inside the oil-filled transformer, the oil decomposes and generates various gases, which causes the contacts of the gas relay to actuate, closes the specified control circuit, and issues an alarm signal in a timely manner or activates the protection element to automatically cut off the transformer. According to the gas generated by the oil, the fault can be divided into heavy gas or light gas conditions. For light gas, it mainly reflects that when the transformer is operating or has a minor fault, the gas decomposed from the oil rises into the gas relay, the air pressure causes the oil level to drop, and the open cup of the relay drops with the oil level. The light gas reed contacts are closed to send a signal. When there is too much gas in the light gas, the gas can be released from the exhaust port of the gas relay; heavy gas mainly reflects a serious internal fault of the transformer, especially a strong gas generated by a fault such as an inter-turn short circuit that cannot be quickly detected by other transformer protections, which pushes the oil flow to impact the baffle. The magnet on the baffle attracts the heavy gas reed contacts, causing the contacts to close and trip. Therefore, to ensure that the gas relay can effectively protect the transformer, it needs to be tested before installation to ensure its protection is effective.

[0003] Currently, the loading and unloading of gas relay detection and the process of auxiliary detection are all manual operations. First, the operator manually picks up the product and places it in the detection station, and then performs a series of auxiliary detection operations such as assembling and tightening bolts, inserting the oil connection pipe, turning the exhaust valve to exhaust gas, and wiring. After the detection is completed, the operator then disassembles the oil discharge pipe, electric clamp, bolts, etc., and finally manually takes out the product for oil control and manually enters the detection results into the MES system. All the above work is done manually, resulting in high labor intensity and low detection efficiency. Content of the Utility Model

[0039] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Embodiment

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present utility model, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0043] The gas relay (also known as: gas relay) is an important device for the non-electric quantity protection of oil-immersed transformers, and it is installed in the pipeline between the conservator and the oil tank of the transformer. When a discharge fault occurs inside the oil-filled transformer, the oil decomposes and generates various gases, which causes the contacts of the gas relay to actuate, closes the specified control circuit, and issues an alarm signal in a timely manner or activates the protection element to automatically cut off the transformer. According to the gas generation situation of the oil, the fault can be divided into heavy gas or light gas situations. For light gas, it mainly reflects that when the transformer is operating or has a minor fault, the gas decomposed from the oil rises into the gas relay, the air pressure causes the oil level to drop, and the open cup of the relay drops with the oil level, and the light gas reed contacts are closed to send a signal. When there is too much gas in the light gas, the gas can be released through the exhaust port of the gas relay; heavy gas mainly reflects a serious internal fault of the transformer, especially a strong gas generated by a fault such as inter-turn short circuit that other transformer protections cannot quickly act on, which pushes the oil flow to impact the baffle, and the magnet on the baffle attracts the heavy gas reed contacts, causing the contacts to close and trip. Therefore, to ensure that the gas relay can effectively protect the transformer, it needs to be tested before installation to ensure its effective protection.

[0044] At present, the loading and unloading of gas relay detection and the process of auxiliary detection are all manually operated. First, the product is manually carried and placed into the detection station, and then a series of auxiliary detection operations are carried out, such as assembling bolts and tightening them, inserting the connecting oil pipe, turning the exhaust valve to exhaust gas, wiring, etc. After the detection is completed, the drain pipe, electric clamp, bolts, etc. are disassembled, and finally the product is manually taken out for oil control and the detection results are manually entered into the MES system. The above work is all manually operated, with a large labor intensity and low detection efficiency.

[0045] To solve the above technical problems, the present utility model proposes an operation detection system 100 for a gas relay 200.

[0046] As Figure 2 shown, it should be noted that the gas relay 200 is any gas relay 200 in the prior art, including an upper cover 201, the upper cover 201 is provided with a positioning hole 2011, one side of the upper cover 201 is provided with an exhaust valve 202 and a plurality of conductive posts 204, the top of the exhaust valve 202 is provided with a knob switch 203, one side of the exhaust valve 202 forms an exhaust port 2021, and the other side of the upper cover 201 is provided with a working mechanism 205, and the working mechanism 205 is used for light gas and heavy gas detection.

[0047] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 11As shown, in an embodiment of the present utility model, the operation detection system 100 includes a material transporting device 1, a feeding device 2, a positioning device 3, a detection device 4, and an oil control device 5. The material transporting device 1 includes a manipulator 11; the feeding device 2 includes a carrying platform 211 for carrying the gas relay 200 to be detected; the positioning device 3 includes a positioning plate 31 and a positioning post 32. The positioning plate 31 has a positioning area 311, and the positioning post 32 is arranged on the positioning area 311. The manipulator 11 is used to transfer the gas relay 200 to be detected on the feeding and carrying platform to the positioning area 311 of the positioning plate 31, so that the positioning post 32 cooperates with the positioning hole 2011 to position the gas relay 200 to be detected; the detection device 4 includes a detection mechanism 41 and a pretreatment mechanism 42. The detection mechanism 41 has a detection area. The manipulator 11 is also used to transfer the gas relay 200 to be detected in the positioning area 311 to the detection area. The pretreatment mechanism 42 is used to perform pretreatment on the gas relay 200 in the detection area, and the detection mechanism 41 is used to detect the gas relay 200 in the detection area; the oil control device 5 includes a support platform 51, a loading platform 52, and a first driving member 53. The loading platform 52 is rotatably connected to the support platform 51, and the first driving member 53 is connected to the loading platform 52; the manipulator 11 is also used to transfer the gas relay 200 in the detection area to the loading platform 52, and drive the loading platform 52 to rotate through the first driving member 53 to control the oil of the gas relay 200; the manipulator 11 is also used to transfer the gas relay 200 on the loading platform 52 to the carrying platform 211.

[0048] Understandably, the operation detection system 100 in this embodiment can automatically complete the automatic loading and unloading process of the gas relay 200, realizing the full automation of the detection work of the gas relay 200. Specifically, first, the gas relay 200 to be detected is placed on the bearing platform 211, and then the manipulator 11 actively locates the position of the gas relay 200 to be detected on the bearing platform 211 to start the feeding process. First, the manipulator 11 clamps the gas relay 200 to be detected and places it on the positioning plate 31, and uses the positioning post 32 to cooperate with the positioning hole 2011 on the gas relay 200 to be detected to position the gas relay 200 to adjust the position accuracy of the gas relay 200 to be detected; after positioning, the manipulator 11 clamps and transfers the gas relay 200 located in the positioning area 311 to the detection area, and the pretreatment mechanism 42 pre-treats the gas relay 200 in the detection area, and then the detection mechanism 41 detects the gas relay 200 in the detection area. Since the manipulator 11 clamps the gas relay 200 that has been positioned by the positioning device 3, it is more convenient for the detection mechanism 41 and the pretreatment mechanism 42 to fix and detect after adjusting the position accuracy first, and there is no need to adjust the position of the gas relay again; then the manipulator 11 transfers the gas relay 200 in the detection area to the carrier platform 52 for oil control. Specifically, the manipulator 11 clamps the detected gas relay 200 in the detection area and transfers it to the carrier platform 52, and the first driving member 53 drives the carrier platform 52 to rotate, and rotates the carrier platform 52 to a suitable angle to perform oil control on the gas relay 200. Oil control is to let the liquid oil remaining in the gas relay 200 after detection flow out. Understandably, when detecting, the working mechanism 205 of the gas relay 200 needs to be placed in the liquid oil to simulate the environment when the gas relay 200 is actually used. Therefore, after detection, the residual liquid oil on the detected gas relay 200 needs to be removed. By rotating the carrier platform 52 to drive the gas relay 200 thereon to rotate, the liquid oil in the open cup on the working mechanism 205 is poured out; finally, the manipulator 11 transfers the gas relay 200 on the carrier platform 52 to the bearing platform 211, and the oil-controlled gas relay 200 is also transferred by the manipulator 11 to complete the unloading process. The above is the automatic detection process of the gas relay 200.

[0049] The automatic feeding and unloading process of the gas relay 200 is realized through the material conveying device 1, the position accuracy of the gas relay 200 to be detected is adjusted by the positioning device 3, and then the gas relay 200 to be detected is detected by the detection device 4. The detected gas relay 200 is processed for liquid oil by the oil control device 5, realizing the full automation of the entire detection work of the gas relay 200, with higher detection efficiency and reduced manual labor intensity.

[0050] As Figure 3As shown, further, the manipulator 11 includes a fixing member 111 and two movable members 112. The two movable members 112 are respectively arranged on opposite sides of the fixing member 111, and both movable members 112 can telescopically move relative to the fixing member 111 to approach or move away from the fixing member 111.

[0051] It can be understood that when the manipulator 11 clamps the gas relay 200, the two movable members 112 telescopically move to clamp the gas relay 200 between the two movable members 112. Specifically, the two movable members 112 are respectively located on both sides of the upper cover 201 and abut against the side edges of the upper cover 201 to clamp the gas relay 200, so that the clamping is more stable, enabling the gas relay 200 to maintain a certain posture during transfer, and the manipulator 11 does not contact the other components of the gas relay 200, thus avoiding damaging the other components of the gas relay 200 during the transfer process.

[0052] As Figures 4 - 6 As shown, further, the feeding device 2 further includes a moving bracket 21 and a fixed bracket 22. The top of the moving bracket 21 has a carrying platform 211. There are at least a plurality of fixed brackets 22, and each fixed bracket 22 forms a fixed space 223 with an opening 2231. The moving bracket 21 can enter and exit the fixed space 223 from the opening 2231, and a locking member 23 is arranged on the fixed bracket 22. The locking member 23 is used to lock the moving bracket 21 entering the fixed space 223 to the fixed bracket 22.

[0053] It can be understood that the carrying platform 211 is arranged on the top of the moving bracket 21, and the moving bracket 21 can move to drive the carrying platform 211 to move. The gas relay 200 to be detected will first be placed on the carrying platform 211, and then the moving bracket 21 is pushed to enter the fixed space 223 from the opening 2231 of the fixed bracket 22, and the moving bracket 21 is fixed by the locking member 23 to prevent the moving bracket 21 from moving, so as to keep the gas relay 200 stationary and facilitate the manipulator 11 to clamp and feed.

[0054] Specifically, the locking member 23 can adopt a corner cylinder in the prior art. When the moving bracket 21 moves to the corresponding position in the fixed space 223, the corner cylinder automatically operates to lock the moving bracket 21.

[0055] In this embodiment, the carrying platform 211 has a plurality of spaced-apart carrying positions, and the carrying positions are set as grooves matching the outer shape of the upper cover 201 of the gas relay 200, for initially positioning the gas relay 200 when it is placed on the carrying platform 211, facilitating the manipulator 11 to clamp it, and then the manipulator 11 clamps the gas relay 200 to the positioning device 3 for further precise positioning.

[0056] Specifically, the carrier table 211 includes a loading carrier table and an unloading carrier table, which are respectively located on each moving support 21. The loading carrier table is used to carry the gas relay 200 to be detected, and the unloading carrier table is used to carry the gas relay 200 after oil control. In this embodiment, only one moving support 21 can enter a fixed space 223.

[0057] It can be understood that when a gas relay 200 needs to be detected, the loading carrier table carrying the gas relay 200 to be detected enters the fixed space 223 of the corresponding fixed support 22 through the moving support 21. After the gas relay 200 on the loading carrier table is detected, the moving support 21 is then moved out of the fixed space 223. When a gas relay 200 is being detected, the unloading carrier table for carrying the gas relay 200 after oil control also moves into the corresponding fixed space 223 through the corresponding moving support 21. After there are enough gas relays 200 after oil control on the unloading carrier table, the moving support 21 is then moved out of the fixed space 223.

[0058] In this embodiment, the unloading carrier table is further divided into a qualified product carrier table and a non - qualified product carrier table. The qualified product carrier table is used to carry the gas relay 200 determined to be qualified after detection, while the non - qualified product carrier table is used to carry the gas relay 200 determined to be unqualified after detection. After detection, the gas relay 200 is placed on the corresponding carrier table 211 according to the detection result for easy distinction. Therefore, during the detection process of the gas relay 200 in this embodiment, at least three carrier tables 211, moving supports 21, and fixed supports 22 are required.

[0059] It should be noted that dividing the carrier table 211 into a loading carrier table, a qualified product carrier table, and a non - qualified product carrier table in this embodiment is only for facilitating the description of the roles played by each carrier table 211 during the detection process of the gas relay 200, and is not used to distinguish the specifications and structures of each carrier table 211. The functions of each carrier table 211 can be interchanged. For example, one of the carrier tables 211 serves as a loading carrier table during one detection process of the gas relay 200, and can also be used as a qualified product carrier table or a non - qualified product carrier table during the next detection process of the gas relay 200.

[0060] Further, the fixed bracket 22 includes a support frame 221 and a support frame 222 supported on the top of the support frame 221. The support frame 221 and the support frame 222 enclose a fixed space 223. The support frame 221 includes a plurality of columns 2211, and the support frame 222 includes a longitudinal rod 2222 and two cross rods 2221. A locking member 23 is provided on the longitudinal rod 2222. The two ends of each cross rod 2221 along its extending direction are respectively a first end 2221a and a second end 2221b. The two first ends 2221a are respectively connected to the two ends of the longitudinal rod 2222, and an opening 2231 is formed between the two second ends 2221b.

[0061] It can be understood that the support frame 221 and the support frame 222 enclose a fixed space 223. The support frame 221 supports the support frame 222 to a certain height, which can better fix the movable bracket 21 and prevent the movable bracket 21 from shaking. Moreover, the support frame 221 includes a plurality of columns 2211, which can evenly bear the gravity of the support frame 222 to make the structure more stable; the support frame 222 includes a longitudinal rod 2222 and two cross rods 2221. The two ends of each cross rod 2221 along its extending direction are respectively a first end 2221a and a second end 2221b. The two first ends 2221a are respectively connected to the two ends of the longitudinal rod 2222, and an opening 2231 is formed between the two second ends 2221b. When the movable bracket 21 enters the fixed space 223 from the opening 2231, the two cross rods 2221 are respectively located on both sides of the carrying platform 211. At the same time, the movable bracket 21 is locked by the locking member 23 on the longitudinal rod 2222, which can prevent the movable bracket 21 from shaking in all directions and further maintain the position accuracy of the gas relay 200 on the carrying platform 211.

[0062] Further, a buffer assembly 24 is also provided on the longitudinal rod 2222 at an interval from the locking member 23. The buffer assembly 24 includes a fixed block 241 and a buffer rod 242. The fixed block 241 is installed on the longitudinal rod 2222. The buffer rod 242 includes a fixed end 2421 and a movable end 2422. The fixed end 2421 is installed on the fixed block 241. The movable end 2422 can elastically expand and contract relative to the fixed end 2421, and the expansion and contraction direction of the movable end 2422 is the same as the extending direction of the cross rod 2221. The movable end 2422 is used to abut against the side wall of the carrying platform 211 of the movable bracket 21 entering the fixed space 223.

[0063] Understandably, by setting the buffer assembly 24, it is avoided that the moving bracket 21 directly contacts the vertical rod 2222 after entering the fixed space 223, thereby generating relatively large noise. Among them, the main component of the buffer assembly 24 that plays a buffering role is the buffer rod 242. After the moving bracket 21 enters the fixed space 223 and is about to contact the vertical rod 2222, the movable end 2422 of the buffer rod 242 first abuts against the bearing platform 211, and then reduces the moving speed of the moving bracket 21, so that the bearing platform 211 does not collide with the vertical rod 2222, or the bearing platform 211 contacts the vertical rod 2222 at a very small speed, thereby avoiding excessive noise.

[0064] Specifically, the buffer rod 242 can adopt the buffer rod 242 in the prior art, and no further description will be given here.

[0065] In one embodiment, two buffer assemblies 24 are provided, and the two buffer assemblies 24 are respectively arranged on both sides of the locking member 23. By means of the two buffer assemblies 24, it is better to avoid the collision between the moving bracket 21 and the vertical rod 2222.

[0066] Further, a plurality of rollers 25 are arranged on each cross bar 2221 at intervals along its extending direction. The rollers 25 are rotatably connected to the cross bar 2221 through bearings; the outer edge of the roller 25 is used for rolling contact and cooperation with the bearing platform 211 on the moving bracket 21 entering the fixed space 223.

[0067] Understandably, by arranging a plurality of rollers 25 on the cross bar 2221, when the moving bracket 21 enters the fixed space 223, the outer edge of the roller 25 is in rolling contact and cooperation with the side surface of the bearing platform 211, avoiding the contact friction between the bearing platform 211 and the cross bar 2221 and generating relatively large noise. Moreover, the outer edges of the rollers 25 on the two cross bars 2221 are both in rolling contact and cooperation with the load platform 52, which can not only avoid the shaking of the bearing platform 211 fixed in the fixed space 223, but also make the movement of the moving bracket 21 in and out of the fixed space 223 smoother and with less resistance.

[0068] Specifically, the outer edge of the roller 25 is preferably made of a soft elastic material to further avoid generating excessive noise.

[0069] As Figure 7 shown, further, an identification member 33 is further arranged on the positioning plate 31. The identification member 33 is used to identify the gas relay 200 in the positioning area 311.

[0070] Understandably, by identifying the gas relay 200 through the identification member 33, relevant information of the gas relay 200 to be detected can be obtained and recorded. After the detection, the detection results can be directly recorded corresponding to the relevant information of the identified gas relay 200, which is more convenient for the statistics and analysis of the detection results of all gas relays 200.

[0071] Specifically, there is a two-dimensional code on the gas relay 200. The recognition member 33 is any automatic code scanner in the prior art, and the relevant information of the gas relay 200 is read by scanning the two-dimensional code on the gas relay 200.

[0072] Specifically, the detection mechanism 41 can adopt an oil tank in the prior art. The detection area is located on the oil tank, and a housing and a oil pipe are arranged near the detection area. When the gas relay 200 to be detected is transferred to the detection area, the housing surrounds the working mechanism 205 of the gas detector, and at the same time the oil pipe connects the space surrounded by the housing and the oil tank, so as to simulate the environment when the gas relay 200 is actually used.

[0073] As Figures 8 - 12 shown, further, the pretreatment mechanism 42 includes a top beam 421, a base 422, a lifting unit 423, a docking unit 424 and a switch unit 425; wherein, the base 422 is slidably connected to the top beam 421; the lifting unit 423 includes a first lifting drive 4231 and a lifting seat 4232. The first lifting drive 4231 is installed on the base 422, the lifting seat 4232 is slidably connected to the base 422, the output shaft of the first lifting drive 4231 is connected to the lifting seat 4232, and the first lifting drive 4231 is used to drive the lifting seat 4232 to lift relative to the base 422 between the initial position and the detection position; the docking unit 424 is installed on the lifting seat 4232, and the docking unit 424 includes an oil connection pipe 4241 and a plurality of detection probes 4242; when the lifting seat 4232 is in the detection position, the oil connection pipe 4241 is connected to the exhaust port 2021, and each conductive column 204 can abut against and conduct with a detection probe 4242, so as to detect the gas relay 200 through the detection probe 4242; the switch unit 425 is installed on the lifting seat 4232, and when the lifting seat 4232 is in the detection position, the switch unit 425 can rotate the knob switch 203 to open or close the exhaust valve 202.

[0074] Understandably, in this embodiment, the pretreatment mechanism 42 is disposed close to the detection mechanism 41. After the manipulator 11 places the gas relay 200 in the material receiving area of the detection mechanism 41, it is necessary to cover the working mechanism 205 of the gas relay 200 with a casing. During this process, there will still be a part of the gas in the accommodation space formed by the casing. After the gas relay 200 is fixed, since the base 422 is slidably connected to the top beam 421, the base 422 can be moved close to the detection area. Thus, by driving the lifting seat 4232 to move downward relative to the base 422 through the first lifting driving member 4231, the lifting seat 4232 can be moved to the detection position; when the lifting seat 4232 is moved to the detection position, all or part of the detection probes 4242 of the docking mechanism on the lifting seat 4232 can be in contact with and conduct electricity with the conductive posts 204, so that each conductive post 204 is in contact with and conducts electricity with a detection probe 4242; and when the lifting seat 4232 is moved to the detection position, the oil connecting pipe 4241 on the lifting seat 4232 can be connected to the exhaust port 2021 at the top of the gas relay 200, and the switch unit 425 on the lifting seat 4232 can also rotate the knob switch 203 at the top of the exhaust valve 202 to open or close the exhaust valve 202; after the exhaust valve 202 is opened through the switch unit 425, the gas in the accommodation space of the casing is discharged from the exhaust port 2021 of the exhaust valve 202 through the oil connecting pipe 4241. By observing whether there is oil flowing out of the oil connecting pipe 4241, it can be judged whether the gas in the fuel tank is completely discharged; the above-mentioned contact and conduction between the detection probe 4242 and the conductive post 204 and the exhaust of the exhaust valve 202 are the pretreatment processes; when the gas is completely discharged and the exhaust valve 202 is closed, the gas relay 200 can be detected by the detection mechanism 41; understandably, the decomposition process of the oil inside it can be controlled by the detection mechanism 41. When the gas generated by the oil decomposition enters the gas relay 200, the gas relay 200 will trigger the light gas protection or heavy gas protection. Through the detection probe 4242 that is electrically connected to the conductive post 204 of the gas relay 200, the execution information on whether the gas relay 200 can effectively execute the light gas protection or heavy gas protection can be obtained, and the detection of the gas relay 200 can be completed by analyzing the execution information.

[0075] Through the pretreatment mechanism 42 of the gas relay 200 of the present utility model, the connection between the exhaust port 2021 of the gas relay 200 and the oil connecting pipe 4241, the opening of the exhaust valve 202 and the connection between the conductive post 204 and the detection probe 4242 and other pretreatment operations can be automatically completed without manual operation. The operation process is simple, with high efficiency and low labor intensity.

[0076] Further, the switch unit 425 includes a lifting structure 4250 and a switch structure 4253; wherein, the lifting structure 4250 is installed on the lifting seat 4232; the switch structure 4253 is installed on the lifting structure 4250, and the lifting structure 4250 is used to drive the switch structure 4253 to lift relative to the lifting seat 4232;

[0077] When the lifting seat 4232 is in the detection position, the switch structure 4253 can descend to be connected to the rotary switch 203, so as to rotate the rotary switch 203 to open or close the exhaust valve 202.

[0078] Specifically, the lifting structure 4250 is installed on the lifting seat 4232, the switch structure 4253 is installed on the lifting structure 4250, and the lifting structure 4250 can drive the switch structure 4253 to lift relative to the lifting seat 4232. When the lifting seat 4232 is in the detection position, the lifting structure 4250 can drive the switch structure 4253 to descend to be connected to the rotary switch 203, thereby rotating the rotary switch 203 to open or close the exhaust valve 202. Through the two-stage lifting of the lifting unit 423 and the lifting structure 4250, the coarse adjustment and fine adjustment of the lifting of the switch structure 4253 can be realized respectively, and the adjustment accuracy is higher.

[0079] In an embodiment of the present invention, the lifting structure 4250 includes a mounting seat 4251 and a second lifting driving member 4252. The second lifting driving member 4252 is installed on the lifting seat 4232. The mounting seat 4251 is slidably connected to the lifting seat 4232. The driving shaft of the second lifting driving member 4252 is connected to the mounting seat 4251. The switch structure 4253 is installed on the mounting seat 4251. The second lifting driving member 4252 is used to drive the mounting seat 4251 to lift relative to the lifting seat 4232; when the lifting seat 4232 is in the detection position, the driving shaft of the second lifting driving member 4252 can drive the mounting seat 4251 to descend, so as to drive the switch structure 4253 to descend to be connected to the rotary switch 203 and rotate the rotary switch 203 to open or close the exhaust valve 202.

[0080] Specifically, the mounting seat 4251 is liftably installed on the lifting seat 4232, the second lifting driving member 4252 is also installed on the lifting seat 4232, the driving shaft of the second lifting driving member 4252 is connected to the mounting seat 4251. By the second lifting driving member 4252, the mounting seat 4251 and the switch structure 4253 on the mounting seat 4251 can be driven to lift, so that the switch structure 4253 can descend to be connected to the rotary switch 203 and rotate the rotary switch 203 to open or close the exhaust valve 201 when the lifting seat 4232 is in the detection position. The structure is simple and relatively reliable. In addition, the second lifting driving member 4252 can adopt a cylinder in the prior art.

[0081] In an embodiment of the present utility model, the mounting base 4251 includes a mounting shell 42511, a connecting block 42512, and an elastic member. The mounting shell 42511 is slidably connected to the lifting seat 4232. The elastic member is disposed inside the mounting shell 42511. The driving shaft of the second lifting driving member 4252 passes through the mounting shell 42511 and is connected to one end of the elastic member. The other end of the elastic member is connected to the mounting shell 42511. The connecting block 42512 is connected to an outer wall on one side of the mounting shell 42511. The switch structure 4253 is mounted on the connecting block 42512. When the lifting seat 4232 is in the detection position, the driving shaft of the second lifting driving member 4252 can drive the mounting shell 42511 and the connecting block 42512 to descend, so as to drive the switch structure 4253 to descend to be connected to the rotary switch 203 and rotate the rotary switch 203 to open or close the exhaust valve 201.

[0082] Specifically, the mounting shell 42511 is slidably connected to the lifting seat 4232. An elastic member is disposed inside the mounting shell 42511 (not shown in the figure). One end of the elastic member is connected to the mounting shell 42511, and the other end of the elastic member is connected to the driving shaft of the second lifting driving member 4252. A connecting block 42512 is further connected to an outer wall on one side of the mounting shell 42511. The switch structure 4253 is mounted on the connecting block 42512. When the lifting seat 4232 is in the detection position, the elastic member can provide a buffering effect for the switch structure 4253 to descend to be connected to the rotary switch 203, thereby avoiding damage to the switch structure 4253 and the rotary switch 203. The structure is reasonable and the durability is higher.

[0083] In an embodiment of the present utility model, the switch structure 4253 includes a rotating rod 42531 and a rotation driving member 42532. The rotating rod 42521 is arranged vertically and is rotatably mounted on the connecting block 42512 about its axial direction. The rotation driving member 42532 is mounted on the mounting shell 42511 and is connected to the top of the rotating rod 42521. A slot with a downward opening is formed at the bottom of the rotating rod 42521. When the lifting seat 4232 is in the detection position, the driving shaft of the second lifting driving member 4252 can drive the mounting shell 42511 and the connecting block 42512 to descend, so as to drive the rotating rod 42521 to descend until the rotary switch 203 is inserted and clamped in the slot, and the rotation driving member 42532 can drive the rotating rod 42521 to rotate about the axial direction of the rotating rod 42521, so as to rotate the rotary switch 203 to open or close the exhaust valve 202.

[0084] In an embodiment of the present utility model, the docking unit 424 further includes a docking seat 4243 and a positioning component 4244. The detection probe 4242, the positioning component 4244, and the oil connection pipe 4241 are all installed on the docking seat 4243. The docking seat 4243 is installed on the lifting seat 4232. The positioning component 4244 can position the docking seat 4243 on the gas relay 200 when the lifting seat 4232 is in the detection position.

[0085] Specifically, the docking seat 4243 is installed on the lifting seat 4232. The positioning component 4244, the detection probe 4242, and the oil connection pipe 4241 are all installed on the docking seat 4243, with a compact and reasonable structure. And through the positioning component 4244, the docking seat 4243 can be positioned on the gas relay 200, so that each conductive column 204 of the gas relay 200 is in contact with and conducts with the detection probe 4242 on a docking seat 4243. The positioning is simple and convenient, and the gas relay 200 is limited in the cavity of the operation table, avoiding inaccurate detection results caused by the movement of the gas relay 200, and improving the reliability of the detection.

[0086] In an embodiment of the present utility model, a plurality of positioning holes 2011 are formed in the upper side of the gas relay 200. The positioning component 4244 includes a plurality of positioning shafts 42441. The plurality of positioning shafts 42441 are installed at the bottom of the docking seat 4243. The number of the positioning shafts 42441 is the same as and corresponds to that of the positioning holes 2011 one by one. Each positioning shaft 42441 can be inserted into its corresponding positioning hole 2011 when the lifting seat 4232 is in the detection position.

[0087] Specifically, a plurality of positioning shafts 42441 are provided at the bottom of the docking seat 4243. By inserting each positioning shaft 42441 into its corresponding positioning hole 2011, the docking seat 4243 can be positioned on the gas relay 200, so that each conductive column 204 of the gas relay 200 is in contact with and conducts with the detection probe 4242 on a docking seat 4243. The positioning is simple and convenient, and the gas relay 200 can be limited in the cavity of the operation table through the cooperation of the plurality of positioning shafts 42441 and the plurality of positioning holes 2011, avoiding inaccurate detection results caused by the movement of the gas relay 200, and improving the reliability of the detection.

[0088] In an embodiment of the present utility model, a buffer pad is further provided at the bottom of each positioning shaft 42441. The buffer pad can provide a buffering effect between the positioning shaft 42441 and the positioning hole 2011, effectively avoiding damage to the positioning shaft 42441 and the positioning hole 2011, and having good durability.

[0089] Such as Figure 13As shown in the figure, further, the oil control device 5 further includes an oil receiving box 55, the oil receiving box 55 is supported on the support platform 51, and the oil receiving box 55 is located below the loading platform 52; the loading platform 52 has an oil control area 521, and a second driving member 54 is further provided at a position on the loading platform 52 close to the oil control area 521. The second driving member 54 is used to push the gas relay 200 transferred to the loading platform 52 to the oil control area 521, so that the gas relay 200 is limited in the oil control area 521.

[0090] It can be understood that by providing an oil control area 521 on the loading platform 52, after the gas relay 200 after detection is transferred to the loading platform 52, the gas relay 200 is further pushed into the oil control area 521 by the second driving member 54, so that the gas relay 200 remains fixed when the first driving member 53 drives the loading platform 52 to rotate. And by providing an oil receiving box 55 below the loading platform 52, when the gas relay 200 after detection is located on the loading platform 52 for oil control, the liquid oil flows into the oil receiving box 55 for recycling, and it also avoids oil dripping everywhere and affecting the environment.

[0091] Further, a counterweight 56 is further provided on the loading platform 52, and the first driving member 53 is used to drive the loading platform 52 to rotate from the initial position to the oil control position; the counterweight 56 is used to make the loading platform 52 located at the initial position when the first driving member 53 does not drive the loading platform 52 to rotate.

[0092] It can be understood that the purpose of oil control is achieved by driving the loading platform 52 to rotate by a certain angle by the first driving member 53. After oil control, the loading platform 52 needs to be restored to the initial position to facilitate receiving the next gas relay 200 for continuous oil control. By providing the counterweight 56, even if the angle of rotation of the loading platform 52 by the first driving member 53 is too large or not enough, resulting in the loading platform 52 not being restored to the initial position, the loading platform 52 can be accurately restored to the initial position under the action of the gravity of the counterweight 56. In addition, the loading platform 52 can be restored to the initial position only by the gravity action of the counterweight 56 without using the first driving member 53 to drive the loading platform 52 to rotate, which is more convenient.

[0093] Specifically, the side of the loading platform 52 that bears the gas relay 200 is the front side, and the counterweight 56 is arranged on the back side opposite to the front side.

[0094] Further, the operation detection system 100 further includes a display device 6. There are two display devices 6, which can be respectively used to display different contents. Specifically, in this embodiment, one display device 6 is used to display the production plan and the status of the operation detection system 100; the other display device 6 is used to display the quality of the gas relay 200, such as the qualification rate, etc., so that the detection results can be displayed through the display device 6, and the detection situation of the gas relay 200 can be understood more quickly.

[0095] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
