DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1 、 one A transformer transport and installation assembly includes a support base 1 installed on a transport vehicle. The support base 1 is pre-fixed on a special transport vehicle through fixing parts, such as fixing bolts. Generally, two groups of support bases 1 are provided to support transformers. During actual transportation, the support base 1 can support multiple transformers.

[0020] Reference Figure 1 and Figure 2 A mobile vehicle 3 is slidably connected to the support base 1, and wheels are provided at the bottom of the mobile vehicle 3. In actual use, the wheels can be driven electrically to move, or they can be pushed manually. The mobile vehicle 3 is pushed to the designated installation position in advance and can be positioned by the positioning block 9 on the support base 1.

[0021] Reference Figure 2 and Figure 3 , a card slot 101 is provided on the support base 1; a card block 201 is fixedly connected to the bottom of the transformer 2 and matches the card slot 101. When transporting, the card block 201 at the bottom of the transformer 2 is accurately inserted into the card slot 101 to ensure the safety of the entire transportation, and it is not easy to move during the transportation process; Reference Figure 2 and Figure 3, the lifting support plate 4 is lifted and set on the mobile vehicle 3; the conical receiving plate 6 is rotatably connected to the lifting support plate 4, the lifting support plate 4 is lifted and lowered on the mobile vehicle 3, first support the transformer on the lifting support plate 4, adjust the position, and then use the lifting support plate 4 to drive the transformer to slowly fall and install it on the card slot 101; Reference Figure 3 and Figure 4 In actual use, when the transformer is loaded onto a vehicle, the conical groove structure of the large circle of the conical receiving plate 6 can be used for receiving and positioning. The conical connector 5 connected to the bottom of the transformer 2 has a receiving groove 601 opened on the inner side of the upper part of the conical receiving plate 6. The top of the conical connector 5 is fixedly connected with a receiving block 501 corresponding to the receiving groove 601. When the transformer 2 is installed on the supporting base 1, the conical connector 5 is inserted into the conical receiving plate 6. The conical connector 5 at the bottom of the transformer 2 can be quickly inserted into the conical receiving plate 6, and the circular center positioning can be quickly performed. As the transformer 2 and the conical connector 5 move downward, the initial center positioning of the transformer is achieved. Reference Figure 2-5 After the transformer is initially positioned at the center, it is necessary to rotate it to ensure that the blocks 201 on both sides of the transformer are inserted into the slots 101. The specific solution is as follows: the adjustment cylinder 7 is symmetrically arranged on the lifting support plate 4, and one end of the adjustment cylinder 7 is slidably and sealedly connected to the push rod 701. The push rod 701 is fixedly connected to the adjustment plate 8, and one side of the adjustment plate 8 is fixedly connected to the gear teeth 801. The outer side of the upper surface of the conical receiving plate 6 is provided with a tooth groove 602 that meshes with the gear teeth 801. After the receiving plug-in block 501 at the bottom of the transformer 2 is inserted into the receiving groove 601, the lifting support plate 4 descends, and the adjusting plate is pushed by the pushing rod 701 on the adjusting cylinder 7. The adjusting plate 8 pushes the conical receiving plate 6 and the transformer 2 to rotate and adjust, so that the blocking block 201 is inserted into the card slot 101, and the conical connector 5 is inserted into the receiving groove 601 for engagement. Then, the pushing rod 701 is pushed to move by the air pressure inside the adjusting cylinder 7. The symmetrically arranged adjusting cylinders 7 can select one of the adjusting cylinders to be opened to achieve rotation in different directions according to the actual offset of the transformer. The inflation and exhaust can be controlled by setting a solenoid valve on the adjusting cylinder 7 for fine adjustment.

[0022] Example 2: Reference Figure 3-Figure 6 The transformer transport and installation assembly is basically the same as that in Example 1. The difference is that, during the specific implementation, the adjustment cylinder 7 is inflated during the downward movement of the transformer 2. The specific structure is as follows: a positioning block 9 is fixedly connected to the support base 1, and an inclined surface 901 is provided on the side of the positioning block 9 close to the lifting support plate 4; The other end of the adjusting cylinder 7 is slidingly and sealedly connected to a push rod 704, which is in abutment with the inclined surface 901. The middle part of the adjusting cylinder 7 is connected to the electromagnetic valve 703. During the descending process of the lifting support plate 4, the push rods 704 on the two adjusting cylinders 7 move under the action of the inclined surface 901, respectively controlling the electromagnetic valves 703 on the adjusting cylinders 7, and controlling the push rod 701 to push the adjusting plate 8. When one of the two adjusting cylinders 7 is needed to push the conical receiving plate 6 to rotate, the electromagnetic valve of the other adjusting cylinder 7 is opened to realize the follow-up movement of the other push rod 701.

[0023] The push rod 701 and the stop rod 704 are both connected to a return spring 702 .

[0024] Example 3: Reference Figure 7 The transformer transport and installation assembly is basically the same as that in Example 1, except that, during the specific implementation, a support airbag 305 is connected to the mobile vehicle 3, and the conical connector 5 is inserted into the conical receiving plate 6 and abuts against the upper end of the support airbag 305. By utilizing the supporting effect of the support airbag 305, the lifting support plate 4 can be lowered in a buffered manner when it is lowered.

[0025] Reference Figure 7 During the specific implementation, further buffering can be performed by fixing an air cylinder 301 on the mobile vehicle 3. A telescopic rod 302 is slidingly sealed at the telescopic end of the air cylinder 301. The telescopic rod 302 is fixedly connected to the bottom side of the lifting support plate 4. A buffer spring 303 is sleeved on the telescopic rod 302. The two ends of the buffer spring 303 are respectively connected to the air cylinder 301 and the lifting support plate 4.

[0026] Reference Figure 2 The mobile vehicle 3 is provided with an air pump 304, and the air delivery end of the air pump 304 is connected to the upper end of the air cylinder 301. Through the setting of the air pump 304, when the lifting support plate 4 is lowered, a piston is provided inside the air cylinder 301, and the telescopic rod 302 is fixedly connected to the piston. The air outlet section of the air cylinder 301 is connected to the upper end of the air cylinder 301 to ensure that the interface is located on the upper part of the piston. When inflating, the piston is pushed downward to achieve descent. In addition, it should be noted that during the specific implementation, a solenoid valve should be installed above the air cylinder 301 to ensure that the gas on the upper part of the piston is discharged smoothly when returning to its original position.

[0027] Reference Figure 7A buffer airbag 1011 is connected to the bottom of the slot 101, a clamping airbag 1012 is connected to the slot 101, a plug-in tube 3051 is connected to the support airbag 305, and a connecting tube 102 connected to the clamping airbag 1012 is provided on the movable base 1. The plug-in tube 3051 is connected to the connecting tube 102 through a plug connector. When the lifting support plate 4 moves downward, the support airbag 305 is compressed, and the compressed gas is fully utilized to enter the clamping airbag 1012, which can effectively clamp the card block 201. In actual use, the external connector of the support airbag 305 has been used to replenish the air in the support airbag 305.

[0028] Example 4: Reference Figure 7-8 , the transformer transportation and installation assembly, on the basis of Example 3, on the one hand, fully utilizes the compressed gas of the support airbag 305 again, and on the other hand, in order to realize the detachable connection of the conical connector 5 to the bottom of the transformer 2 so as to facilitate the pushing out of the mobile vehicle 3 and the installation of the next transformer, the following quick release method is adopted.

[0029] The upper end of the conical connector 5 is fixedly connected to the plug column 10, and the bottom of the transformer 2 is fixedly connected to the connecting column 202 with a slot 2021. The inner side of the slot 2021 is provided with a bayonet 2022 corresponding to the clamping column 1003. A sliding hole 1001 is provided in the plug column 10. The sliding hole 1001 is connected to a symmetrical clamping column 1003 through a clamping spring 1002. The clamping column 1003 is slidably sealed in the sliding hole 1001. The conical connector 5 is provided with a bayonet 2022 corresponding to the sliding hole 1001. The vent holes 502 are connected at both ends, and the upper end of the support air bag 305 is connected to a plug-in air head, which is plugged and connected to the vent hole 502; when disassembly is required, it is only necessary to open the solenoid valve provided on the vent hole 502, and the air flow enters the sliding hole 1001, thereby pushing the card column 1003 out of the bayonet 2022. At this time, the lifting support plate 4 only needs to move down a certain distance to achieve disengagement. During the specific implementation, the conical connector 5 is pre-installed at the bottom of the transformer 2.
