Description
Technical Field
[0001] The invention belongs to the technical field of power devices, and particularly relates to a support adjusting device for power transformer conservators. Background Art
[0002] The conservator of a power station is an important device for reducing and preventing the oxidation and moisture absorption of transformer insulating oil, playing the role of storing and replenishing oil, and ensuring that the transformer oil tank is always full of oil. When it is necessary to replace or maintain the conservator, due to the large volume and heavy weight of the conservator, if the conservator body is directly placed on the ground, it is not conducive to quick access and hoisting. However, the existing conservator support devices have the following problems: First, most of the support components are fixed and non-adjustable structures, and cannot be adjusted according to the size of the conservator. Therefore, when the support components do not match the size of the conservator, it is extremely easy to occur accidents such as tipping over, resulting in damage to the conservator or injury to construction workers, and the safety is not high. Second, the support height of the support components cannot be adjusted. Generally, one side of the conservator is installed on a bracket, and the heights of the brackets are not uniform. Therefore, it is impossible to make an adaptive adjustment to the height change of the support components according to the height of the bracket or the actual support height requirement, resulting in low practicability. Even due to the large height difference at both ends, it cannot be used, making the work unable to proceed smoothly. Therefore, it is very necessary to provide a support adjusting device for power transformer conservators with reasonable structure, adjustable support range, adjustable support height, safety and reliability.

[0032] As Figure 1-7 shown, a support and adjustment device for a power oil conservator includes an oil conservator body 1 and a support mechanism 5. A bracket 2 is arranged below one side of the oil conservator body 1, and an arc-shaped frame 3 with an arc surface matching the oil conservator body 1 is arranged at the upper end of the bracket 2. A support mechanism 5 is arranged below the other side of the oil conservator body 1. The support mechanism 5 is installed above the height adjustment mechanism 4. The support mechanism 5 includes a bottom plate 51 and a plurality of scissor support assemblies 52 arranged at intervals transversely along the bottom plate 51. The height position of the support mechanism 5 is adjusted by the height adjustment mechanism 4 to facilitate effectively supporting the oil conservator body 1 in cooperation with the bracket 2 and the arc-shaped frame 3.
[0033] The scissor support assembly 52 includes a "U"-shaped support 201. A set of slide rails 202 are arranged inside the support 201. A bidirectional driver 203 is arranged above the inner side of the support 201. Reverse lead screws 204 are power-connected to both sides of the bidirectional driver 203, and the reverse lead screws 204 are respectively connected to the support 201 through bearing seats.
[0034] A lead screw seat 205 is fitted and installed outside the reverse lead screw 204. A set of sliding seats 206 that are slidably connected to the slide rails 202 are arranged at the bottom of the lead screw seat 205. Cross arms 207 are arranged at both side ends of the lead screw seat 205. A cross shaft rod 208 is arranged at the cross connection between the cross arms 207. Support rollers 209 are installed above the cross arms 207.
[0035] In this embodiment, the working principle of the support mechanism is as follows: Start the bidirectional driver. The bidirectional driver drives the reverse lead screws on both sides to rotate respectively. The reverse lead screws drive the lead screw seats to move on the slide rails through the sliding seats, so that a group of lead screw seats approach or move away from each other. Since a group of cross arms are movably connected in an "X" shape through the cross shaft rods, when the lead screw seats approach each other, the lower ends of the cross arms will be driven to approach each other, causing the upper ends of the cross arms to also approach each other, reducing the opening size at the upper ends of the cross arms; on the contrary, when the lead screw seats drive the lower ends of the cross arms to move away from each other, the opening size at the upper ends of the cross arms will be increased. On the one hand, this enables the support mechanism to adjust the support range according to the oil pillow body of different diameter specifications, making it applicable to the support work of oil pillow bodies of various sizes and greatly improving its practicability; on the other hand, when supporting an oil pillow body of a fixed size, the opening size at the upper ends of the cross arms can be increased to enlarge the support range, making the oil pillow support more stable and preventing problems such as the oil pillow tipping over, resulting in damage to the oil pillow or injury to construction workers. Compared with the prior art, the actual use effect is better, more stable, and safe and reliable.
[0036] The present invention is a power oil pillow support adjustment device. During use, when maintaining the oil pillow, place the end without the bracket 2 of the removed oil pillow body 1 on the support mechanism 5, making the oil pillow body 1 convenient to access and hoist; the support mechanism 5 is arranged on the height adjustment mechanism 4, and the height position of the support mechanism 5 can be adjusted to facilitate matching the height of the bracket 2 to effectively and reliably support the oil pillow body 1, making the oil pillow body 1 more stable and preventing problems such as the oil pillow body 1 tipping over, resulting in damage or injury to construction workers. The support is stable and the construction is safer; in addition, according to the actual support requirements in use, the height of the other end relative to the bracket 2 can be adjusted to adjust the height change at both ends of the oil pillow body 1 while avoiding a large height difference at both ends; the present invention has the advantages of reasonable structure, adjustable support range, adjustable support height, safety and reliability.
