Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing, specifically to a high-end converter transformer outgoing line device flipping fixture and flipping method. Background Technology

[0002] The outgoing line device is a core insulating component connecting the transformer leads and bushings. It effectively improves the high electric field distribution in the outgoing line area, ensuring the electrical stability of the outgoing line area and playing a crucial role in ensuring the safe and stable operation of the power system. High-end converter transformers, due to their higher electrical requirements, have more complex structural designs, characterized by large main body height, numerous insulation layers, large volume, and heavy weight. During the manufacturing process, the outgoing line device often needs to be flipped to switch between vertical and horizontal positions due to component assembly and transportation requirements. However, in existing technologies, most high-end converter transformer outgoing line devices are flipped by using ropes tied to the middle of the device. This flipping method is highly dangerous and the outgoing line device is prone to deformation during the flipping process.

[0003] Existing technologies also include some tooling for assisting in the rotation of transformer output devices. For example, patent CN217376994U discloses a transformer output device rotation frame. In use, a fixed frame is fixed to the ground, the transformer output device is placed on the rotation frame, and the corner rings on the output device are positioned at the arc-shaped limiting plate. The output device is then secured to the rotation frame with cable ties. A crane hook is then attached to the lifting hole at the front end of the rotation frame, and the crane pulls the rotation frame. The vertical travel wheels of the rotation frame move upwards along the vertical track of the fixed frame, while the horizontal travel wheels move forward along the horizontal track of the fixed frame. After the rotation frame rotates 90°, the crane stops, completing the process of changing the output device from a horizontal to a vertical position. However, this device has an overly complex structure, occupies a large area, and is relatively cumbersome to operate. Summary of the Invention

Detailed Implementation

[0034] The invention will now be described in further detail with reference to the accompanying drawings.

[0035] like Figures 1-8 As shown, the present invention includes a flipping fixture body 1 inserted into the cable outlet device 2, and the flipping fixture body 1 includes a support plate assembly at end A and a tray 103 at end B. The support plate assembly is connected to the tray 103 via multiple connecting rods 102. Multiple clamping block assemblies 104 are evenly distributed along the circumferential direction on the tray 103, such as... Figures 3-8 As shown, the clamping block assembly 104 includes a block base 107, a clamping block 106, and a locking assembly 105. The clamping block 106 is rotatably disposed within the block base 107, and the block base 107 has a first locking hole 1073 and a second locking hole 1074 on one side. The locking assembly 105 is disposed on the clamping block 106, and the locking assembly 105 has a retractable locking shaft 1053. Figure 4As shown, when the clamping block 106 closes and abuts against the cable outlet device 2, the locking pin 1053 is inserted into the first locking hole 1073, as... Figure 6 As shown, when the clamping block 106 lifts up to release the wire outlet device 2, the locking insert shaft 1053 is inserted into the second locking hole 1074.

[0036] like Figure 8 As shown, in this embodiment, the locking assembly 105 includes a locking housing 1052, a drive screw 1051, and a spring 1054. The locking insert shaft 1053 is movably disposed in the locking housing 1052, and the spring 1054 is sleeved on the rear of the locking insert shaft 1053. A guide groove 10521 is provided on one side of the locking housing 1052, and the drive screw 1051 passes through the guide groove 10521 and connects to the locking insert shaft 1053. An operator pushes the drive screw 1051 along the guide groove 10521 to move, thereby driving the locking insert shaft 1053 to move so that it is inserted into the corresponding locking hole on the pressure block seat 107 for locking. In addition, a limiting groove 10522 is provided on the guide groove 10521. When the drive screw 1051 retracts to the position of the limiting groove 10522 and rotates upward into the limiting groove 10522, locking is achieved, and the locking insert shaft 1053 cannot move at this time.

[0037] like Figure 7 As shown, in this embodiment, the clamping block 106 is provided with a threaded hole 1063, such as... Figure 8 As shown, the locking housing 1052 of the locking assembly 105 has a threaded portion 10523 at its front end that mates with the threaded hole 1063 to achieve the purpose of installing the locking assembly 105 onto the clamping block 106.

[0038] like Figure 7 As shown, in this embodiment, the clamping block 106 is generally L-shaped, and a clamping block 1062 is provided at the front stop of the clamping block 106, as... Figure 6 As shown, the pressure block seat 107 is provided with a pressure block receiving groove 1072 with a rear opening, and the front side groove wall A end of the pressure block receiving groove 1072 forms a limiting platform 1075. The clamping pressure block 106 is placed in the pressure block receiving groove 1072 and its B end is hinged to the pressure block seat 107. When the clamping pressure block 106 is closed, the clamping block 1062 abuts against the limiting platform 1075.

[0039] like Figure 4 As shown, in this embodiment, the pressure block seat 107B end is provided with a hinge shaft 1071, as... Figure 7 As shown, the clamping block 106B has a hinge hole 1064 at one end for the hinge shaft 1071 to pass through.

[0040] like Figure 4 As shown, in this embodiment, the clamping block 106 is provided with a drive handle 1061 on the opening side of the clamping block receiving groove 1072. The clamping block 106 can be driven to rotate by moving the drive handle 1061.

[0041] like Figures 1-2 As shown, in this embodiment, the support plate assembly of the flipping fixture body 1 includes a support plate 101 and a threaded sleeve 108, and the two support plates 101 are connected by the threaded sleeve 108. The A end of the connecting rod 102 passes through the corresponding threaded sleeve 108 and is threadedly connected to the first lifting eye 1021, as shown. Figure 3 As shown, the tray 103 is provided with a through hole 1032, and as... Figure 2 As shown, end B of the connecting rod 102 passes through the corresponding through hole 1032 and is threadedly connected to the second lifting ring 1031. In use, the main and auxiliary hooks of a crane are used to lift two ropes respectively. One rope is connected to the first lifting ring 1021, and the other rope is connected to the second lifting ring 1031. Then, the crane is operated to pull the ropes to complete the rotation of the cable outlet device 2. Additionally, the support plate 101 can be placed on the stepped insulation part of the cable outlet device 2 as support. This effectively prevents the cable outlet device 2 from deforming due to uneven force during rotation. Furthermore, to prevent the lifting ropes from squeezing and deforming the end insulation cardboard of the cable outlet device 2 during lifting, the end support plate 101 needs to be slightly higher than the innermost layer of insulation cardboard of the cable outlet device 2.

[0042] like Figure 1 As shown, the B end of the cable outlet device 2 is provided with a cable outlet device flange 201, and the middle of the cable outlet device flange 201 is provided with a flange sleeve 202. In one application example of the present invention, each clamping block assembly 104 on the tray 103 passes through the flange sleeve 202. Then, the operator inserts his hand into the inner hole of the flange sleeve 202 and pushes the drive handle 1061 to make the clamping block 106 rotate and close, and abut against the inner wall of the cable outlet device 2 to achieve fixation. In addition, the drive handle 1061 can also be pushed with the help of tools such as push rods as needed to increase the convenience of operation.

[0043] The working principle of this invention is as follows:

[0044] In use, the present invention can be assembled as needed and then installed into the cable outlet device 2 as a whole. The clamping block 106 is rotated and closed to abut against the inner wall of the cable outlet device 2 for fixation. However, the disadvantage of this method is that if it is found that the overall length of the tooling of the present invention does not match the length of the cable outlet device 2, the tooling of the present invention needs to be removed as a whole, and then disassembled and replaced with a connecting rod 102 of appropriate length.

[0045] Alternatively, this invention can be installed using another method as needed, which specifically includes the following steps:

[0046] Step 1: Connect the support plate 101 with the threaded sleeve 108 to form a support plate assembly;

[0047] Step 2: Place the assembled support plate assembly at end A of the outgoing line device 2, and place the support plate 101 in the support plate assembly at the stepped insulation part of the outgoing line device 2 as a support.

[0048] Step 3: Place the tray 103 outside the flange 201 of the outlet device and make each clamping block assembly 104 on the tray 103 pass through the flange sleeve 202 in the middle of the flange 201 of the outlet device.

[0049] Step 4: The operator pushes the drive handle 1061 to close the clamping block 106 against the inner wall of end B of the cable outlet device 2, and then pushes the drive screw 1051 in the locking assembly 105 to insert the locking pin 1053 into the first locking hole 1073 on the block seat 107 to lock the position of the clamping block 106.

[0050] Step 5: Insert the connecting rod 102 into the threaded sleeve 108 in the support plate assembly and extend it out through the through hole 1032 on the tray 103. Then, thread the first lifting ring 1021 to the A end of the connecting rod 102 and thread the second lifting ring 1031 to the B end of the connecting rod 102. While installing the first lifting ring 1021 and the second lifting ring 1031, press and fix the support plate assembly and the tray 103.

[0051] In addition, during this step, the operator can replace the connecting rod 102 in a timely manner according to the actual situation, and then install the first lifting ring 1021 and the second lifting ring 1031, so that the tooling does not need to be taken out, disassembled and replaced as a whole.

[0052] Step 6: Lift the two lifting ropes from the main and auxiliary hooks of the crane respectively. One rope is connected to the first lifting ring 1021, and the other rope is connected to the second lifting ring 1031. Then, operate the crane to pull the ropes to complete the flipping of the cable outlet device 2.

[0053] Compared to existing transformer outgoing device flipping frames and other tooling, the present invention has a simple and compact overall structure, and its flipping is achieved by inserting it into the outgoing device 2, without occupying additional space.
