Abstract
The invention discloses a support device and method for a large-scale transformer. The support device comprises a sleeve and a lead screw, wherein a threaded hole is formed in the sleeve; the lead screw is arranged in the sleeve via the threaded hole; at least one opening, in which a screwing rod can penetrate, is formed in the upper section of the lead screw, and is parallel to the upper surface of the lead screw; a flat plate connected with the sleeve is arranged on the lower surface of the sleeve, so as to form an L-shaped structure. As the lead screw and the sleeve are combined to replace a jack, not only is the use cost low, but also the problem of high effectiveness losing possibility of the jack can be solved, the service life of the support device is prolonged, and the use is convenient; due to the arrangement of the flat plate, the L-shaped structure of the flat plate and the sleeve is more stable as the support device is usually arranged on an edge of the transformer for supporting, and the condition of unbalanced stress on the transformer caused by skewing of the support device can be avoided effectively.
Description
Technical field
The present invention relates to the setting of switch board, be particularly used for the support device and method of high-power transformer。
Background technology
High-power transformer weighs more than 20 ton, this transformator is generally arranged on outdoor device base, but the growth along with the time of operation, transformator needs to return factory's overhaul or passage and move, carry, when transport, high-power transformer generally adopts jack pair transformator to be supported, so because of the structural design of the weight of transformator with jack itself, jack pad assembly inner plunger seals and easily lost efficacy, jack pad assembly is caused to be susceptible to damage, cause supporting seat shorter for service life, often changing jack, use cost is high；It addition, because the structure of jack itself is vertical, is susceptible to when supporting, and top lifting surface area is less, cause transformator to be subject to force unbalance, support instability, it is easy to deposit or in transportation at transformator, transformator is caused and collides with。
It is therefore desirable to have transformator is supported by an a kind of new support arrangement。
Summary of the invention
For the problems referred to above, in order to solve the deficiencies in the prior art, spy arranges a kind of simple in construction, can make the support device and method for high-power transformer of transformator stress balance。

Further, described flat board is provided with the groove for bolt or screw traverse, because when transformator supports, support baseboard is usually apertured, at this moment by arranging bolt or screw traverse gap realization fixing flat board so that stability of strutting system is further enhanced。
Further, described sleeve and described flat board are structure as a whole。
The using method of the described support arrangement for high-power transformer, specifically comprises the following steps that
1) bottom of leading screw is placed in sleeve, multiple sleeves with leading screw are placed in the place estimating to support transformator；
2) for avoiding sliding, bolt or screw is adopted to fix flat board through the groove on flat board；
3) adopt and tighten bar and the height of leading screw is adjusted through perforate。
The invention adopt another scheme that: for a support arrangement of high-power transformer, including sleeve and leading screw, it is installed with screw in sleeve or is provided with screw in sleeve over top, when above screw is located at sleeve, can screw be fixed on the supporting seat of transformer bottom, screwed hole it is provided with in sleeve, leading screw is located in sleeve by screwed hole bottom screw, at least one it is provided with for tightening the perforate that bar penetrates at the top of leading screw, perforate is parallel to leading screw upper surface, the lower surface of sleeve is gripper shoe, the diameter being sized larger than sleeve of gripper shoe, at least two support columns being obliquely installed it are provided with between gripper shoe and sleeve, gripper shoe has multiple groove, the setting of gripper shoe and support column is again based on the stress consideration of a support arrangement, when bottom support lifting surface area is bigger, support effect is better, but consider the weight of a support arrangement, gripper shoe is preferably circular configuration。
Further, described groove be shaped as annular。
Further, the lower surface on the top of leading screw, gripper shoe is respectively equipped with rubber blanket with insulation, and in addition for increasing friction force, the top of leading screw can arrange decorative pattern。
Further, for the insulation effect of a support arrangement, paint is scribbled on the surface of described sleeve。
Further, described support plate removably connects with leading screw top, when the somewhere bearing height that transformator needs is lower than its elsewhere, it is possible to is dismantled by a support plate, further increases the altitude mixture control of a support arrangement；Certainly, prop up support plate to be structure as a whole with leading screw。
The using method of the described support arrangement for high-power transformer, specifically comprises the following steps that
1) bottom of leading screw is placed in sleeve, multiple sleeves with leading screw are placed in the place estimating to support transformator；
2) for avoiding sliding, bolt or screw is adopted to fix gripper shoe through the groove in gripper shoe；
3) adopt and tighten bar and the height of leading screw is adjusted through perforate。
Further, multiple sleeves with leading screw divide arranged in rows, and the sleeve of adjacent row shifts to install, and often row's sleeve is arranged according to annular。
The invention has the beneficial effects as follows:
1, replacing jack by leading screw and sleeve combination, not only use cost is cheap, simultaneously, it is to avoid jack seals the problem easily lost efficacy, and extends the service life of a support arrangement, simple and convenient。
2, by the setting of flat board so that flat board and sleeve shaped l-shaped structure, because mostly a support arrangement is to be supported on the edge of transformator, L-type structure supports more stable, and effectively prevent that to prop up support arrangement crooked and cause the situation of transformator discontinuity equalization。
3, by the setting of gripper shoe and support column, and then the rigidity of whole support arrangement and the stability of support are improved。
4, it is located at the top of leading screw by a support plate, increases the lifting surface area on leading screw top, extend the service life of a support arrangement further。
