In the application, the width of the power transformer to be detected should be greater than the width of the moving-in conveying belt 3, the first moving-out conveying belt 4 and the second moving-out conveying belt 5, so that the delivery assembly 7 can lift the equipment to be detected from the two ends of each conveying belt.

[0030] When the application is used, the power transformer equipment to be detected is conveyed to the upper area of the detection platform 1 through the moving-in conveying belt 3, at this time, the delivery assembly 7 is controlled to move along the detection platform 1 through the driving mechanism 6, until the delivery assembly 7 moves to the area corresponding to the moving-in conveying belt 3, then the power transformer equipment to be detected on the moving-in conveying belt 3 is supported through the lifting structure of the delivery assembly 7, after the support is completed, the driving mechanism 6 is reversely controlled to rotate, the power transformer equipment to be detected is conveyed to the detection area, and when the power transformer equipment to be detected moves to the position close to the end plate 2, the positioning detection mechanism 8 and the locking mechanism 9 are automatically triggered, the power transformer equipment to be detected is positioned through the positioning detection mechanism 8, and then the power transformer equipment to be detected is locked through the locking mechanism 9, so that the subsequent detection process can be carried out, after the detection is completed, the qualified power transformer equipment to be detected is conveyed to the first moving-out conveying belt 4, and if it is unqualified, it is conveyed to the second moving-out conveying belt 5, so that the purpose of separate conveying is achieved.

[0031] The driving mechanism 6 comprises a motor 24 and a gear 26, the bottom of the detection platform 1 is screwed with a power box 23, one end of the power box 23 is screwed with the motor 24, the output end of the motor 24 is inserted with a driving shaft 25, and the surface of the driving shaft 25 is keyed with the gear 26.

The positioning, correction and locking processes of the power transformer equipment are all automatically realized by only relying on the pushing process of the driving mechanism 6 to the delivery assembly, the utilization rate of the power equipment is improved, the device running process is more coherent, and the detection efficiency is improved.

[0032] Specifically, after starting the motor 24, the gear 26 on the surface of the driving shaft 25 is driven to rotate, the gear 26 is matched with the rack 22, and the entire delivery assembly 7 can be driven to move in translation. The delivery assembly 7 is supported and slides in the inside of the chute 11 through the bottom roller 19, and is also assisted and limited to guide through the strip-shaped hole 10. In the conveying process of the power transformer equipment to be tested, the delivery assembly 7 is always provided with a translation effect by the driving mechanism 6.

[0033] The delivery assembly 7 includes a fixed support plate 15, a movable support plate 18 and a transmission plate 20, the top of the transmission plate 20 is welded with a convex plate 21, the bottom of the transmission plate 20 is integrally formed with a rack 22, the fixed support plate 15 is welded at the top end of the transmission plate 20. The surface of the fixed support plate 15 is screwed with an electric lifting rod 17 and a lifting column 16, and the electric lifting rod 17 and the lifting column 16 are arranged at one end between the fixed support plate 15 and the movable support plate 18, the movable support plate 18 is screwed at the top end of the lifting column 16 and the electric lifting rod 17, and the fixed support plate 15 and the movable support plate 18 maintain a parallel state. The fixed support plate 15 passes through the bottom of the first moving-out conveyor belt 4 and the second moving-out conveyor belt 5, the movable support plate 18 passes through the top of the first moving-out conveyor belt 4 and the second moving-out conveyor belt 5, the bottom of the fixed support plate 15 is inserted with a roller 19, the bottom of the roller 19 is embedded into the inside of the sliding groove 11, and the rack 22 is used to engage with the gear 26.

At the same time, through the hydraulic lifting combined with the linear movement, the moving-in and moving-out processes of the large power transformer are more stable and reliable, which solves the problem that the conventional rotary disc type detection scheme cannot stably convey and transfer multiple large power transformers.

[0034] Specifically, the delivery assembly 7 supports the equipment to be tested placed on the surface through the fixed support plate 15 and the movable support plate 18, and the movable support plate 18 is controlled to move up through the electric lifting rod 17, so as to increase the distance between the fixed support plate 15 and the movable support plate 18. Through this effect, when the equipment to be tested is carried from the moving-in conveyor belt 3 in the early stage, the movable support plate 18 is first controlled to move down to the bottom through the electric lifting rod 17, at this time the movable support plate 18 is located below the moving-in conveyor belt 3, at this time the movable support plate 18 is controlled to move up through the electric lifting rod 17, so as to lift the placed equipment from the bottom of both ends of the moving-in conveyor belt 3. After lifting, the delivery assembly 7 is controlled to move to the area between the moving-in conveyor belt 3 and the first moving-out conveyor belt 4 through the driving mechanism 6, then the electric lifting rod 17 is controlled to retract, the cavity area between the first moving-out conveyor belt 4 and the second moving-out conveyor belt 5 and the fixed support plate 15 and the movable support plate 18 is aligned, so as to ensure that the delivery assembly 7 can support the equipment to pass through the surface of the first moving-out conveyor belt 4 and the second moving-out conveyor belt 5, and finally move the equipment to be tested to the position close to the end plate 2.

[0035] The positioning detection mechanism 8 comprises a side baffle 27, a top plate 32 and a detection electrode column 33.

The inside of the groove 14 is inserted with a guide rod 28. The two ends of the guide rod 28 are welded on the surface of the fixed column 29. The top of the side baffle 27 is welded with a vertical column 31. The top of the vertical column 31 is welded with the top plate 32. The bottom surface of the top plate 32 is installed with the detection electrode column 33. One end of the side baffle 27 is embedded into the inside of the groove 14, and the side baffle 27 is sleeved on the surface of the guide rod 28.

[0036] Specifically, when the to-be-tested device is moved to the position close to the end plate 2 through the delivery assembly 7, the surface of the device is first abutted on the inclined plate 30. Through the support of the inclined plate 30, the side baffle 27 is controlled to slide along the guide rod 28, and then the top plate 32 and the detection electrode column 33 at the top are controlled to move synchronously. Therefore, the final electrode column is controlled by the size of the device itself, and it is ensured that the detection electrode column 33 and the port on the device are in the same horizontal line vertical plane.

[0037] The locking mechanism 9 comprises a transmission frame 34, a telescopic rod 37 and a locking plate 38. The inner side of the transmission frame 34 is welded with a linkage baffle 39. The top of the transmission frame 34 is screwed with the telescopic rod 37. The end of the telescopic rod 37 is screwed with the locking plate 38. The surface of the telescopic rod 37 is sleeved with a spring 35. The two ends of the spring 35 are abutted on the surface of the transmission frame 34 and the support sleeve ring 36 respectively. The bottom of the linkage baffle 39 is used for pressing on the surface of the transmission plate 20. The locking plate 38 is used for abutting on the surface of the to-be-tested device. The positioning and locking process of the entire power transformer device can be automatically completed during detection. The device has high running stability. Even if the power transformer device is slightly rotated to cause deviation during transportation, the detection electrode column 33 for plugging at the top can be aligned with the port on the power transformer device before final detection, so that the process of batch detection has higher fault tolerance.

[0038] Specifically, when the delivery assembly 7 approaches the end plate 2, the linkage effect of the positioning detection mechanism 8 is completed, and the equipment is slightly lifted by the electric lifting rod 17 until the top of the equipment is higher than the height of the locking plate 38, at which time the drive mechanism 6 can be started to control the movement of the delivery assembly 7, so that the convex plate 21 is abutted on the linkage stop rod 39, the telescopic rod 37 and the locking plate 38 are pulled to move, and finally the locking plate 38 is extruded from the outside to the equipment to be tested, and after the equipment to be tested is clamped and locked by the end plate 2, the electric lifting rod 17 can be controlled to extend, so that the port at the top of the equipment is connected with the detection electrode column 33 above, and after the detection is completed, the equipment to be tested is first controlled to move downward, and after passing through the locking plate 38, the equipment to be tested is driven to move reversely, and the subsequent moving-out process is performed.
