[0051] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] See also Figures 1 to 8 , Figures 14 to 16 The transformer auxiliary detection and maintenance operation table provided by the present invention is now described. A transformer auxiliary detection and maintenance operation table includes a base 1, two operation chambers 2, two sliding seats 3, two lifts 4 and two drivers 5. The lower end of the base 1 is provided with a first running wheel 11; the two operation chambers 2 are both installed on the base 1, and the end of the operation chamber 2 away from the base 1 is provided with a second running wheel 21; the two operation chambers 2 are arranged at intervals, and form a long space 12 for accommodating the electric pole 7 and the transformer 8, and the upper ends of the two operation chambers 2 are provided with a connecting plate 22; the operation chamber 2 has an opening 23 on the side close to the long space 12, The operating chamber 2 has a plurality of support structures 24 arranged in sequence from top to bottom, and the other side of the operating chamber 2 is provided with a plurality of main inlets and outlets 25 corresponding to the support structures 24; two sliding seats 3 are respectively installed on the opposite sides of the two operating chambers 2, and correspond to the main inlets and outlets 25 on the lower side; one end of the sliding seat 3 passes through the main inlet and outlet 25 and is slidably connected to the bottom surface of the lower support structure 24 in the operating chamber 2; two elevators 4 are respectively installed on the two sliding seats 3; two drivers 5 are both installed on the lower support structure 24 and connected to the sliding seat 3.

[0053] Compared with the prior art, the transformer auxiliary detection and maintenance operating table provided by the present invention is more convenient to use. When in use, the base 1 and the operating chamber 2 are controlled by means of the first running wheel 11 and the second running wheel 21 to be located on one side of the electric pole 7, and the long space 12 corresponds to the electric pole 7, thereby pushing the entire operating table to move so that the electric pole 7 and the transformer 8 are located in the long space 12; the staff climbs onto the elevator 4 from the sliding seat 3, passes through the main entrances and exits 25 with the help of the elevator 4, and thus enters the support structure 24 inside the operating chamber 2, and the staff inspects the transformer 8 through the opening 23. Multiple support structures 24 are arranged at intervals up and down, and the staff can stand on the support structures 24 corresponding to different inspection positions, thereby conveniently and accurately inspecting the transformer 8, and there is no need to stand on the transformer 8, which has higher safety. At the same time, for the electric poles 7 and transformers 8 with complex installation environments, the staff first enters the operation chamber 2, starts the driver 5 to retract the sliding seat 3 to the supporting structure 24 of the operation chamber 2, thereby reducing the width of the entire operating table and adapting to different installation environments; and through the connecting plate 22, the staff in the two operation chambers 2 can quickly change positions, so as to quickly perform maintenance operations on the transformer 8.

[0054] The width of the main entrance and exit 25 is greater than the width of the sliding seat 3 and the elevator 4. When the staff enters the supporting structure 24 on the lower side, they can directly pass through the corresponding main entrance and exit 25 to enter the supporting structure 24 without boarding the elevator 4.

[0055] A plurality of through openings are provided on the outer wall of the operation chamber 2 for transferring tools and the like to the support structure 24 in the operation chamber 2 .

[0056] See also Figures 1 to 6 As a specific embodiment of the transformer auxiliary detection and maintenance operation table provided by the present invention, the operation chamber 2 includes a rear panel 26 and a side panel 27, and the rear panel 26 is vertically arranged; one end of the rear panel 26 is installed on the base 1, and the other end extends outward in a direction away from the base 1; the main inlet and outlet 25 is opened on the rear panel 26; the second walking wheel 21 is arranged at the lower end of the rear panel 26; the number of side panels 27 is two, respectively on both sides of the rear panel 26; the two side panels 27 are arranged in parallel and spaced apart; the connecting plate 22 is installed on the two side panels 27 of the two operation chambers 2 close to the base 1; the side panel 27 away from the base 1 is provided with an auxiliary inlet and outlet 28 for entering the operation chamber 2; multiple support structures 24 are fixed on the rear panel 26 and the two side panels 27, and the auxiliary inlet and outlet 28 corresponds to the support structure 24 on the lower side.

[0057] The rear panel 26 and the two side panels 27 form an installation space, and a plurality of support structures 24 are arranged in parallel and spaced apart from top to bottom, and the support structures 24 are used to carry workers to perform maintenance operations.

[0058] The three sides of each support structure 24 are respectively fixedly connected to the two side panels 27 of the rear panel 26, thereby improving the reliability of the support structure 24. The main entrance and exit 25 correspond to each support structure 24 one by one, so that the staff can enter the support structure 24 smoothly.

[0059] An auxiliary entrance 28 is provided on the side plate 27 away from the base 1 , and the staff can also enter the lowermost support structure 24 through the auxiliary entrance 28 .

[0060] The lowermost support structure 24 is flush with the lower ends of the side panels 27 and the rear panel 26, while the upper support structure 24 is lower than the upper ends of the side panels 27 and the rear panel 26. The side panels 27 and the rear panel 26 provide protection for the workers to prevent them from accidentally falling. This method also improves the ventilation effect in the entire operating chamber 2.

[0061] See also Figure 1 , Figure 3 and Figure 4 As a specific embodiment of the transformer auxiliary detection and maintenance operating table provided by the present invention, a rotatably connected extension plate is provided on the support structure 24 on the lower side of the two operating chambers 2, and the extension plate is used to adjust the width of the long space 12.

[0062] When the width of the length space is greater than the width of the transformer 8, the extension plate is in a horizontal state, thereby increasing the standing area for the staff, and the staff can perform maintenance more conveniently and accurately.

[0063] When the width of the transformer 8 is large, the width of the length space needs to be increased. The staff manipulates the extension plate to rotate to a vertical state, shortening the width of the extension plate so that the electric pole 7 and the transformer 8 can enter the length space more smoothly.

[0064] The extension plate is connected to the support structure 24 through a hinge shaft, and a first square hole is arranged on the extension plate on one side of the hinge shaft, and two second square holes corresponding to the first square hole are arranged on the support structure 24. When the extension plate is in a horizontal state or a vertical state, the two second square holes are respectively aligned with the first square hole, and then the square shaft is used to pass through the first square hole and the second square hole to position the extension plate, ensuring that the extension plate can be stably in a horizontal state or a vertical state.

[0065] See also Fig. 9 As a specific implementation of the transformer auxiliary detection and maintenance operating table provided by the present invention, each supporting structure 24 is provided with a safe haven 6, and the safe haven 6 is surrounded by multiple insulating plates 61; multiple safe havens 6 are connected up and down, and a climbing ladder 62 is provided on the inner wall of the safe haven 6; the safe haven 6 on the lower supporting structure 24 is connected to the auxiliary inlet and outlet 28.

[0066] When the transformer 8 is being repaired, in order to prevent a danger from occurring due to a failure of the transformer 8 , the staff can quickly enter the safe haven 6 and use the insulating plate 61 to prevent the danger of electric shock.

[0067] Since the plurality of support structures 24 are connected, the staff on the high support structure 24 can move downward from top to bottom with the aid of the climbing ladder 62 and escape from the secondary entrance 28. Since the staff are always in the refuge area 6 during the downward movement, the staff are always in a safe state.

[0068] See also Figure 3 , Fig.10 and Fig.11 As a specific implementation of the transformer auxiliary detection and maintenance operating table provided by the present invention, the rear panel 26 is rotatably connected to the base 1, and the first running wheel 11 and the second running wheel 21 are both universal wheels; the rear panel 26 is driven to rotate ninety degrees around the base 1 so that the openings 23 of the two operating chambers 2 are oriented in the same direction; the rear panel 26 is driven to rotate one hundred and eighty degrees around the base 1 so that the openings 23 of the two operating chambers 2 are opposite to each other.

[0069] The rear panel 26 on the supporting structure 24 is rotatably connected to the base 1, so when the environment of the electric pole 7 and the transformer 8 is not suitable for the operation table to be repaired, the state of the operation table is changed.

[0070] When the two rear panels 26 are rotated outward by ninety degrees, the two operating chambers 2 and the base 1 form a long strip structure, which greatly reduces the width of the entire operating table and is suitable for narrow maintenance environments. At the same time, this method makes the openings 23 of the two operating chambers 2 face the same direction, so the operating table can be used to simultaneously maintain two adjacent transformers 8, thereby improving maintenance efficiency.

[0071] When the two rear panels 26 are rotated outwards 180 degrees, the two operating chambers 2 and the base 1 are still in a U-shaped structure, and the size of the entire operating table remains unchanged, but the openings 23 of the two operating chambers 2 are separated from each other. This method is suitable for two transformers 8 arranged in parallel, so that the two transformers 8 can be repaired, which improves the maintenance efficiency.

[0072] See also Figures 1 to 6 As a specific implementation of the transformer auxiliary detection and maintenance operating table provided by the present invention, a first slide rail 241 is provided on the lower support structure 24, and a slide groove slidably matched with the first slide rail 241 is provided at the lower end of the sliding seat 3.

[0073] The slide groove on the sliding seat 3 is connected to the first slide rail 241 . After the driver 5 is started, the sliding seat 3 is pulled to slide along the slide groove, so that the sliding seat 3 and the elevator 4 pass through the main entrance 25 and enter the support structure 24 .

[0074] When the driver 5 is started, the lift 4 needs to be lowered to the lowest position. The driver 5 adopts an electric push rod. Two first slide rails 241 are provided, and two slide grooves are provided at the lower end of the sliding seat 3.

[0075] See also Figure 1 and Figure 2 As a specific implementation of the transformer auxiliary detection and maintenance operating table provided by the present invention, a shielding door 251 is provided on the main inlet and outlet 25 for closing the operating chamber 2; a second slide rail is provided on the outer wall of the operating chamber 2, and the length direction of the second slide rail is consistent with the length direction of the operating chamber 2, and the lower end of the shielding door 251 is slidably connected to the second slide rail.

[0076] After the staff enters the support structure 24, the shielding door 251 is controlled to slide along the second slide rail, thereby shielding the main entrance and exit 25. The staff can work without being affected by the outside world, and the safety and accuracy are high.

[0077] The second slide rail is arranged to be fitted on the outer wall of the operating chamber 2 , and the shielding door 251 slides along the outer wall of the operating chamber 2 without interfering with the elevator 4 .

[0078] See also Figures 1 to 6 As a specific embodiment of the transformer auxiliary detection and maintenance operating table provided by the present invention, an end panel 13 is provided between the two operating chambers 2, the end panel 13 is fixed on the base 1, and a window 14 corresponding to the electric pole 7 and the transformer 8 is opened on the end panel 13, and the window 14 is detachably connected to the end panel 13.

[0079] The end panel 13 is provided to seal one end of the two operating chambers 2 to avoid external influence. A viewing window 14 is provided on the end panel 13 so that external staff can observe the maintenance operation through the viewing window 14.

[0080] The viewing window 14 is detachably connected to the end panel 13, and the viewing window 14 can be removed when necessary.

[0082] When the staff stands on the support structure 24 to inspect the transformer 8, since multiple support structures 24 are fixedly installed in the operation chamber 2 and arranged discontinuously, it is impossible to meet the inspection and maintenance of various positions of the transformer 8.

[0083] The support structure 24 is set as a transformable structure, with two support plates 242 located on both sides and a mounting gap 243 formed therebetween, and an adjustment plate 244 is installed in the mounting gap 243 to fill the mounting gap 243 and make the entire support structure 24 complete.

[0084] At the same time, an adjustment plate 244 is provided to be slidably connected in the installation notch 243 , and a lifter 245 is provided on the upper support structure 24 . The lifter 245 is installed upside down, and the free end of the lifter 245 is fixedly connected to the adjustment plate 244 .

[0085] After the staff stands on the adjustment plate 244, the jacking device 245 is started to control the adjustment plate 244 to slide up and down, so as to accurately reach the position to be repaired of the transformer 8. Optionally, the staff sits on the adjustment plate 244 for maintenance, which is more labor-saving and convenient. The jacking device 245 is an electric push rod or the like.

[0087] The four connecting columns 246 are arranged in a rectangular array and fixed on the two support plates 242 in pairs; the two connecting columns 246 on the same group of connecting columns 246 are respectively set close to the rear panel 26 and the opening 23, so as not to affect the staff walking and moving on the support plates 242.

[0088] A guide groove 247 is provided on each connecting column 246 , and two guide blocks 248 are respectively provided on both side surfaces of the adjusting plate 244 . The four guide blocks 248 are respectively slidably connected into the four guide grooves 247 , and the free end of the lifter 245 enters into the guide groove 247 from top to bottom and is fixedly connected to the guide block 248 .
