Abstract
The present invention discloses a crane frame of a portable transformer. The crane frame comprises a base, an outer door frame and an inner door frame. The base comprises a left longitudinal arm, a right longitudinal arm, a front cross arm which bestrides and connects to the middle/back parts of the left longitudinal arm and the right longitudinal arm, and a back cross arm which bestrides and connects to the back ends of the left longitudinal arm and the right longitudinal arm. The outer door frame comprises the following components: a pair of columns which are fixed on the front cross arm of the base, a door beam which bestrides the back side parts of the tops of the pair of columns, and a bracket which bestrides the back side parts of the upper parts of the pair of columns. The inner door frame comprises a pair of straight beams and a cross beam which bestrides the upper ends of the pair of straight beams. The inner door frame is slidably mounted on the inner side surfaces of the pair of columns of the outer door frame. The crane frame of the portable transformer according to the invention can keep hoisting height of the crane under a precondition that the height of the crane is reduced, thereby ensuring high stability and high safety in transportation and hoisting processes of transformer equipment.
Description
Technical field
The present invention relates to a kind of vehicle frame of portable transformer lifting machine.
Background technology
Along with rapid development of national economy, the electric power system construction also steps on a new stage, the annual a considerable number of electrical equipment of newly-increased installation that needs, and existing power equipment needs regular maintenance simultaneously.
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., the installation of this situation electrical equipment such as voltage transformer can lift by rubber tired crane.Another kind of situation is that operating environment is relatively poor even abominable, as farmland, mountain area etc., this situation rubber tired crane can't arrive, this moment, the installation method of electrical equipment such as voltage transformer was: at first utilize the power engineering car that voltage transformer is transported near the nearest highway in place of erection, adopt a dead lift to the place of erection then, build support at last the voltage transformer lifting is put in place.
Under second kind of situation, electrical equipment from highway to this section of place of erection at least tens meters at most hundreds of rice even transportation distance and whole dependence of hoisting process of going up km manually finish, so there is following defective in current approach:
(1) transportation is low with lifting efficient
Because the power engineering car of transportation electrical equipment can only be anchored on the highway, electrical equipment such as voltage transformer rely on the mode of a dead lift to finish by lorry to that segment distance that lifts the place fully, and building of support needs long setup time, and therefore transportation is lower with lifting efficient.
(2) labour intensity is big
Electrical equipment such as voltage transformer are made up of iron core, winding, capacitor oil and accessory thereof etc., nearly 1 ton of the weight of miniature transformer, even near 2 tons, so heavy equipment is from tens meters of power engineering car a dead lifts, hundreds of rice even go up km to lifting the place, workmen's labour intensity is excessive, and construction cost is too high.
(3) security risk is big
Electrical equipment all is farmland or mountain area as the distance of voltage transformer carrying, in the way gully is arranged usually, 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 composition element, 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 objective of the invention is to overcome the defective of prior art, a kind of vehicle frame of portable transformer lifting machine is provided, it can make the lifting altitude of lifting machine can be higher than the height of complete machine, guarantees 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 that left and right vertical arm, one are connected across the preceding transverse arm of postmedian of left and right vertical arm and the back transverse arm of a rear end that is connected across left and right vertical arm; Described outer mast comprises column, the Men Liang of a top rear that is connected across a column and the carriage of a top rear side that is connected across a column on a pair of preceding transverse arm that is fixed on described base; Described inner upright mounting comprises that a pair of straight beam and one are connected across the crossbeam of 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 comprise two columns that are connected described outer mast correspondingly the bottom lateral surface and before triangle support frame between the upper surface of transverse arm.
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 installed in described outer mast correspondingly.
The vehicle frame of portable transformer lifting machine of the present invention, 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 be under the prerequisite that reduces the 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 that detachably makes, and is detachable in case of necessity, convenient transportation.And weight own is light, is convenient to installation and removal.
