Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment maintenance equipment technology, and in particular to a hoisting tool for converter valve reactors in converter stations. Background Technology
[0002] The converter valve in a converter station is a core converter device in a DC power transmission project, playing a crucial role in the energy conversion process. A converter valve consists of multiple valve layers, each with an insulating beam along its outer edge and containing several reactors. In DC power transmission projects, reactors have long service lives and reliable installation methods. However, during long-term operation, reactor failures, damage, and aging are inevitable. A decrease in reactor inductance is a common converter valve fault, requiring the converter valve to be under maintenance when troubleshooting.
[0003] The existing converter station lacks specialized reactor hoisting equipment for the converter valves. When replacing the reactors, the main method is to carry out the replacement work by manpower in the air. This replacement method is not only difficult to maintain, but also takes a long time, resulting in longer power outage time due to converter valve failure. Utility Model Content
[0004] In view of this, it is necessary to provide a hoisting fixture for the converter valve reactor in a converter station, which can complete the aerial replacement of the reactor by means of mechanical devices, thereby reducing the replacement time of the reactor and thus shortening the power outage time of the converter valve.
[0005] This utility model provides a hoisting fixture for converter valve reactors in a converter station, including a fixing component, a track component, and at least one hoisting component. The fixing component is used to fix the top surface of the track component to the insulating beam of each valve layer. One end of the track component is flush with the outer edge of the valve layer, and the other end extends from the outer edge of the valve layer. The hoisting component is slidably mounted on the bottom surface of the track component. The hoisting end of the hoisting component is used to lift the reactor, and the transport end of the hoisting component is used to transport the reactor out of each valve layer along the track.
[0006] Preferably, the fixing assembly includes at least two fixing groups with the same structure. Each fixing group includes two connectors and a fixing member. The two connectors are symmetrically installed on both sides of the track assembly. The bottom end of the fixing member is fixedly connected to the top end of the two connectors. The connectors are used to fixally connect to the insulating beams of each valve layer.
[0007] Preferably, the track assembly includes a slide rail and two limiting members. The top surface of the slide rail is connected to the fixing assembly, and the two limiting members are installed at both ends of the slide rail to prevent the hoisting assembly from sliding off the slide rail.
[0008] Preferably, the bottom surface of the slide rail is equipped with two hoisting components, which can lift the reactor from both sides of the reactor through the hoisting ends of the two hoisting components, thereby increasing the stability of the reactor during the hoisting process.
[0009] Preferably, each hoisting component includes a transport component and a hoisting component. The transport component is slidably mounted on the bottom surface of the slide rail, and the fixed end of the hoisting component is mounted on the transport component. The hoisting end is used to hoist the reactor.
[0010] Preferably, the bottom surface of the slide rail is provided with two racks, and the top surface of the transport component is provided with a first dual-axis motor. The two drive shafts of the first dual-axis motor are each equipped with gears, and each gear is meshed with a rack, so that the transport component moves on the bottom surface of the slide rail by driving the gears to rotate through the first dual-axis motor.
[0011] Preferably, the bottom surface of the slide rail is provided with two tracks, and the top surface of the transport component is provided with a second dual-axis motor. Each of the two drive shafts of the second dual-axis motor is equipped with a transport wheel, and each drive wheel is slidably connected to a track, so that the transport component moves on the bottom surface of the slide rail by driving the transport wheel to rotate through the second dual-axis motor.
[0012] The aforementioned converter valve reactor hoisting fixture includes a fixing component, a track component, and a hoisting component. The fixing component is used to fix the top surface of the track component to the insulating beam of each valve layer. One end of the track component is flush with the outer edge of the valve layer, and the other end extends from the outer edge of the valve layer. The hoisting component is slidably installed on the bottom surface of the track component. The hoisting end of the hoisting component is used to lift the reactor, and the transport end of the hoisting component is used to transport the reactor out of each valve layer along the track. In this way, the reactor is lifted from each valve layer by the hoisting component, transported out of the valve layer along the track component, and then hoisted to the ground to complete the reactor replacement operation. This eliminates the need for manual labor to complete the aerial replacement of the reactor, reduces the reactor replacement time, and shortens the power outage time due to converter valve failure.

Detailed Implementation
[0017] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0018] Please refer to Figure 1 This utility model provides a hoisting fixture 10 for converter valve reactors in a converter station, including a fixing component 20, a track component 30, and a hoisting component 40. The fixing component 20 is used to fix the top surface of the track component 30 to the insulating beam of each valve layer 51. One end of the track component 30 is flush with the outer edge of the valve layer 51, and the other end extends from the outer edge of the valve layer 51. The hoisting component 40 is slidably mounted on the bottom surface of the track component 30. The hoisting end of the hoisting component 40 is used to hoist the reactor 52. The transport end of component 40 is used to transport the reactor 52 out of each valve layer 51 along the track; thus, the reactor 52 is lifted from each valve layer 51 by the hoisting component 40, and transported out of the valve layer 51 along the track component 30, and then the reactor 52 is hoisted to the ground to complete the replacement operation of the reactor 52. This eliminates the need to rely on manpower to complete the aerial replacement operation of the reactor 52, reduces the replacement time of the reactor 52, and shortens the power outage time of the converter valve 50.
[0019] Please refer to Figures 2 to 3 Furthermore, the fixing assembly 20 includes at least two fixing groups 21 with the same structure. Each fixing group 21 includes two connectors 211 and a fixing member 212. The two connectors 211 are symmetrically installed on both sides of the track assembly 30. The bottom end of the fixing member 212 is fixedly connected to the top end of the two connectors 211. The connectors 211 are used to fixally connect with the insulating beams of each valve layer 51, thereby fixing the track assembly 30 onto the insulating beams of each valve layer 51.
[0020] Please refer to Figure 2 Furthermore, the track assembly 30 includes a slide rail 31 and two limiting members 32. The top surface of the slide rail 31 is connected to the fixing assembly 20, and the two limiting members 32 are installed at both ends of the slide rail 31 to prevent the hoisting assembly 40 from sliding off the slide rail 31.
[0021] In one embodiment, the bottom surface of the slide rail 31 is equipped with two hoisting components 40, which are used to lift the reactor 52 from both sides through the hoisting ends of the two hoisting components 40, thereby increasing the stability of the reactor 52 during the hoisting process. Thus, when hoisting the reactor 52, the positions of the two hoisting components 40 are first adjusted so that the hoisting ends of the two hoisting components 40 are respectively connected to both sides of the reactor 52, so that when hoisting the reactor 52, an upward pulling force can be applied to the reactor 52 from both sides at the same time, thereby enabling the reactor 52 to remain stable during the hoisting process.
[0022] Please refer to Figure 2 Furthermore, the hoisting assembly 40 includes a transport component 41 and a hoisting component 42. The transport component 41 is slidably mounted on the bottom surface of the slide rail 31 to drive the hoisting component 42 to move on the bottom surface of the slide rail 31, thereby removing the reactor 52 from each valve layer 51. The fixed end of the hoisting component 42 is mounted on the transport component 41, and the hoisting end is used to lift the reactor 52.
[0023] In one embodiment, the bottom surface of the slide rail 31 is provided with two racks, and the top surface of the transport component 41 is provided with a first dual-axis motor. The two drive shafts of the first dual-axis motor are each equipped with gears, and each gear is meshed with a rack. The transport component 41 moves on the bottom surface of the slide rail 31 by driving the gears to rotate through the first dual-axis motor. In this way, the position of the transport component 41 on the bottom surface of the slide rail 31 can be precisely controlled.
[0024] In one embodiment, the bottom surface of the slide rail 31 is provided with two tracks, and the top surface of the transport component is provided with a second dual-axis motor. Each of the two drive shafts of the second dual-axis motor is equipped with a transport wheel, and each drive wheel is slidably connected to a track. The transport component 41 moves on the bottom surface of the slide rail 31 by driving the transport wheel to rotate through the second dual-axis motor. In this way, the transport component 41 can move quickly on the bottom surface of the slide rail 31.
[0025] In this embodiment, the lifting device 42 is a manual hoist or an electric hoist, so that the operator can control the lifting device 42 to lift or lower the reactor 52.
