The frame comprises a base, an outer gantry frame and an inner gantry frame, wherein the base comprises left and right longitudinal arms, a front cross arm across the rear middle parts of the left and right longitudinal arms and a rear cross arm across the rear ends of the left and right longitudinal arms; the outer gantry frame comprises a pair of vertical columns fixed on the front cross arm of the base, a gantry beam across the rear sides at the tops of the pair of vertical columns and a bracket across the rear sides at the upper parts of the pair of vertical columns; the inner gantry frame comprises a pair of straight beams and a cross beam across the upper ends of the pair of straight beams; the inner gantry frame is glidingly mounted on the inner side surfaces of the pair of vertical columns of the outer gantry frame. The frame provided by the utility model can be used for keeping the lifting height of the lifting machine on the premise of reducing the height of the lifting machine and guaranteeing the stability and the safety of transformer equipment in transporting and lifting processes.
Description
Technical field
The utility model relates to a kind of vehicle frame 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, and a kind of vehicle frame of portable transformer lifting machine is provided, and it can make the lifting altitude of lifting machine higher than the height of complete machine, guarantee stability and the safety of transformer equipment transportation and hoisting process.
The technical scheme that realizes above-mentioned purpose is: a kind of vehicle frame of portable transformer lifting machine, comprise a base, an outer mast and an inner upright mounting, 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 outer mast comprises column, the Men Liang of a top rear that is connected across a column and the bracket of a top rear side that is connected across a column on a pair of front transverse arm that is fixed on described base; Described inner upright mounting comprises a pair of straight beam and a crossbeam that is connected across a pair of straight beam upper end, and this inner upright mounting is slidably mounted on the medial surface of a column of described outer mast.
The vehicle frame of above-mentioned portable transformer lifting machine, wherein, the column of described outer mast adopts channel-section steel as the slideway of described inner upright mounting, and a roller that can embed a column of described outer mast is installed on the lateral surface of a pair of straight beam of described inner upright mounting correspondingly.
The vehicle frame of above-mentioned portable transformer lifting machine, wherein, described vehicle frame also comprises that two are connected to the lower outside face of a column of described outer mast and the triangle support frame between the upper surface of front transverse arm correspondingly.
The vehicle frame of above-mentioned portable transformer lifting machine, wherein, described vehicle frame also comprises the handle on the middle and upper part trailing flank of a pair of column that is arranged on correspondingly described outer mast.
The vehicle frame of portable transformer lifting machine of the present utility model, adopt two-door shelf structure, inner upright mounting can slide up and down along outer mast, make the lifting altitude of lifting machine can be higher than the height of complete machine, therefore can reduce under the prerequisite of complete machine height, guarantee stability and the safety of transformer equipment transportation and hoisting process, and weight own is light, is convenient to installation and removal.Base adopts the structure detachably making, detachable if desired, convenient transportation.And weight own is light, is convenient to installation and removal.
