Abstract
The utility model relates to a liftable bottom frame for a high-voltage test, which comprises a horizontal base. Traveling wheels are arranged below the horizontal base, a lifting cylinder further perpendicularly fixed on the horizontal base comprises a first lifting cylinder, a second lifting cylinder and a third lifting cylinder which are nested from bottom to top, and a flange connected with a tested product is arranged at the upper end of the third lifting cylinder. The lifting cylinder needs to be assisted by a crane during lifting, positioning lifting at four height positions can be realized by the aid of lifting of each lifting cylinder respectively, and corresponding positioning connectors and screws are used for fixing. Moreover, the flanges with various diameters can be used for being connected with the tested products, so that the purpose of fast and convenient mounting is achieved.
Description
Technical field
The utility model belongs to the power test equipment technical field, relates to a kind of insulator test unit, especially a kind of high-potting liftable underframe that is used for.
Background technology
Along with development and national economy, the rapid increase of power demand, the usage quantity of China's electric product is improving constantly, the extra-high voltage networking that urban and rural power grids construction and upgrading, Three Gorges Projects, " transferring electricity from the west to the east " and national cross-region will be carried out, all will create conditions for the development of more spy, extra high voltage network and transformer station, current conversion station etc., the construction of these engineerings brings unprecedented opportunities and challenge also for the development of switch and insulator industry.Nowadays China's electrical network will be realized from the leap of high pressure to extra-high voltage, and in extra-high voltage grid was built, the transformer station of each grade all be unable to do without insulator.
Because the underframe height of frequent discovery test product has a significant impact the dielectric level of test product in the insulator process of the test, according to GB GB/T 775.2-2003 " insulator test method (electrical test method) ", test product should uprightly be installed on the ground connection underframe, a square installed surface should be arranged above the metal frame, installed surface should not influence test effect with the shape of lower carriage, should make underframe height 50% must not exceed the vertical projection district of installed surface with top for this purpose, when test product height during less than 2500mm, the underframe height should be 2500mm, when the test product height more than or equal to 2500mm during less than 3200mm, the underframe height should be 3000mm, when the test product height more than or equal to 3200mm during less than 4200mm, the underframe height should be 4000mm, and when test product height during more than or equal to 4200mm, the underframe height should be 5000mm.Present most of underframe all can't satisfy the test of voltage levels product, and because can't move, has caused many difficulties for the test product test connection.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of high-potting liftable underframe is provided, and this underframe can move freely it in the test Room by reasonable structural design, selects suitable installation site.Can effectively reduce the transmission of electricity accident that causes because of insulator arc-over etc. in the high-tension line.
The purpose of this utility model solves by the following technical programs:
This high-potting liftable underframe, comprise horizontal base, described horizontal base has traveling wheel, go back vertical fixing on the described horizontal base lifting tube is arranged, described lifting tube comprises that by down from the last first nested successively lifting tube, second lifting tube and the 3rd lifting tube, the upper end of described the 3rd lifting tube is provided with and the product to be tested flange connecting.
Above-mentioned horizontal base is made up of supporting plate and the channel-section steel that is arranged on the supporting plate, and described the 3rd lifting tube is fixed on the supporting plate by the cable-stayed type channel-section steel that is arranged on around it.
Be provided with positioning link between above-mentioned first lifting tube and second lifting tube, second lifting tube and the 3rd lifting tube.
Lifting tube of the present utility model needs by crane auxiliary in lifting process, by can realizing the location lifting of four height and positions respectively to the lifting of each section lifting tube, and has corresponding positioning link and screw to be used for fixing.Can realize that with the test product flange connecting flange of multiple different-diameter is connected in addition, accomplish to install fast, easily purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 is supporting plate; 2 is channel-section steel; 3 is first lifting tube; 4 is second lifting tube; 5 is the 3rd lifting tube; 6 is flange; 7 is traveling wheel.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, this kind high-potting liftable underframe, comprise horizontal base, have the traveling wheel 7 that is used to make whole liftable underframe motion at horizontal base, go back vertical fixing on the horizontal base lifting tube is arranged, this lifting tube is made up of three sections nested tubes, has respectively by descending from last nested successively first lifting tube 3, second lifting tube 4 and the 3rd lifting tube 5, in the upper end of the 3rd lifting tube 5 product to be tested flange connecting 6 is set.In the utility model, in order to satisfy the connection needs of different test products, the size of flange 6 can be provided with plurality of specifications.
Horizontal base of the present utility model is made up of supporting plate 1 and the channel-section steel 2 that is arranged on the supporting plate 1, and the 3rd lifting tube 5 is fixed on the supporting plate 1 by the cable-stayed type channel-section steel 2 that is arranged on around it.Be provided with positioning link between first lifting tube 3 and second lifting tube 4, second lifting tube 4 and the 3rd lifting tube 5.
In most preferred embodiment of the present utility model, lifting tube needs by crane auxiliary in lifting process, can realize 2.5 meters respectively by lifting to first lifting tube 3, second lifting tube 4 and the 3rd lifting tube 5,3 meters, 4 meters, the location lifting of 5 meters these four height and positions, and have corresponding positioning link and screw to be used for fixing.The flange that can realize multiple different-diameter with test product flange connecting 6 is connected, and accomplishes to install fast, easily purpose.
