Description
Technical field
The utility model relates to a kind of Overthrow preventing device of portable transformer lifting machine.
Background technology
Along with developing rapidly of national economy, electric power system construction also steps on a new stage, and needs every year the newly-increased a considerable number of electrical equipment of installing, and simultaneously existing electrical equipment needs regular maintenance.
The place of erection of electrical equipment totally can be divided into two kinds of situations, and a kind of is that operating environment is better, and as urban district, highway etc., this situation electrical equipment can lift by rubber tired crane as the installation of voltage transformer.Another kind of situation is that operating environment is poor even severe, as farmland, mountain area etc., this situation rubber tired crane cannot arrive, now electrical equipment as the installation method of voltage transformer is: first utilize electric engineering car that voltage transformer is transported to the near Highway nearest from place of erection, then adopt a dead lift to place of erection, last setting support puts voltage transformer lifting in place.
In the second situation, electrical equipment from highway to this section of place of erection at least tens meters of transportation distance and whole dependence of hoisting process that hundreds of rice even km at most manually complete, there is following defect in current method therefore:
(1) transportation is low with lifting efficiency
Owing to transporting the electric engineering car of electrical equipment, can only be anchored on highway, electrical equipment relies on the mode of a dead lift to complete by lorry to that segment distance that lifts place as voltage transformer completely, and support build need to be longer setup time, therefore transportation is lower with lifting efficiency.
(2) labour intensity is large
Electrical equipment is comprised of iron core, winding, capacitor oil and accessory thereof etc. as voltage transformer, nearly 1 ton of the weight of miniature transformer, even approach 2 tons, so heavy equipment even km to lifting place from tens meters of electric engineering car a dead lifts, hundreds of rice, workmen's labour intensity is excessive, and construction cost is too high.
(3) security risk is large
Electrical equipment is all farmland or mountain area as the distance of voltage transformer carrying, in way, conventionally has gully, and volume of transformer is huge and heavy, and therefore transportation is being contained potential safety hazard greatly with hoisting process.
Along with upgrade of rural power grids, upgrading, as the voltage transformer of one of electrical network important component, increase newly with transformation quantity and increase sharply, therefore voltage transformer being lifted puts in place repeats and hard work being one.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, a kind of Overthrow preventing device of portable transformer lifting machine is provided, it can be in irregular place and lifting machine at full load prevent that car load from tumbling, guarantee stability and the safety of transformer equipment transportation and hoisting process.
The technical scheme that realizes above-mentioned purpose is: a kind of Overthrow preventing device of portable transformer lifting machine, comprise base and four supports that are arranged on correspondingly left front end, right front ends, left back end and the right rear end of base, wherein, described in each, support and comprise that respectively the Connection Block of the end that is connected to base, an one end are connected to support beam and the supporting leg that is connected and contacts with ground with the other end of support beam on Connection Block.
The Overthrow preventing device of above-mentioned portable transformer lifting machine, wherein, described base comprises left and right longitudinal arm, the front transverse arm of postmedian and a rear transverse arm for a rear end that is connected across left and right longitudinal arm that is connected across left and right longitudinal arm; Described left front support is in the mode vertical with the longitudinal arm in a described left side or in the mode of the extension of the longitudinal arm in a described left side, be arranged on the left front end of described base; Described right front support is in the mode vertical with the longitudinal arm in the described right side or in the mode of the extension of the longitudinal arm in the described right side, be arranged on the right front ends of described base; Described left back support is in the mode vertical with the longitudinal arm in a described left side or in the mode of the extension of the longitudinal arm in a described left side, be arranged on the left back end of described base; Described right back support is in the mode vertical with the longitudinal arm in the described right side or in the mode of the extension of the longitudinal arm in the described right side, be arranged on the right rear end of described base.
The Overthrow preventing device of portable transformer lifting machine of the present utility model, four bights at base have increased respectively support, strengthened the balance of base, can be in irregular place and lifting machine at full load prevent that car load from tumbling, guarantee stability and the safety of transformer equipment transportation and hoisting process.Make the complex job environment such as adaptation mountain region, field of lifting machine.
