Abstract
The utility model relates to the technical field of auxiliary substation maintenance equipment and in particular relates to a transformer on-load tap-changer core lifter. The core needs to be lifted out in the process of maintaining a transformer on-load tap-changer of a substation, the lifting cost is high by utilizing a crane, a lifting arm is difficultly controlled, and the core and an outer wall are collided to damage the equipment. The transformer on-load tap-changer core lifter comprises a transverse beam, upright posts, supporting legs and a lifting mechanism, wherein the upright posts are in two-section telescopic structures; the two upright posts are assembled at two ends of the transverse beam through a connecting sleeve; the lifting mechanism is arranged on the middle section of the transverse beam through a guide sleeve; the supporting legs which are fixedly connected with equipment to be maintained is arranged at the lower end of the upright post. The transformer on-load tap-changer core lifter is simple in structure, small in size, light in weight and simple and convenient to operate, the lifting height, the lifting position and the span of the transverse beam can be adjusted according to the equipment to be maintained, so that on-load tap-changer products with different models are matched. In the lifting process, the lifter is fixed together with the equipment to be maintained, and collision between the core and the inner wall of the shell is effectively avoided.
Description
Technical field
The utility model relates to substation's auxiliary apparatus for repairing technical field, specifically a kind of on-load tap changers of transformers core body lifter.
Background technology
Along with the increase in demand of electric energy, the increasing of consumption of current, the on-load tap changers of transformers operation of substation is comparatively frequent; When load ratio bridging switch operation reaches producer's access times or occurs defect, need to overhaul load ratio bridging switch.Common operating mode is to use crane lifting, after the core body of load ratio bridging switch is promoted, overhauls or change operation.Because core body and the gap between outer wall of load ratio bridging switch are less, adopt crane to lift by crane that not only cost of investment is large, and crane volume is large, arm stability is wayward, during operation, very easily produces and rocks, in lifting process, the core body of load ratio bridging switch is easy to touch body skin, causes the contact accidental impact on core body and outer wall impaired, has increased operating risk, waste time and energy, maintenance operating efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of on-load tap changers of transformers core body lifter, and volume is little, lightweight, simple in structure, and convenient operation can adapt to the on-load tap changers of transformers of Multiple Type.
The technical solution of the utility model: comprise crossbeam, column, leg and derricking gear; Derricking gear top is fixed with orienting sleeve, and derricking gear is sleeved on the stage casing of crossbeam by orienting sleeve, and by the fastening location of jackscrew;
Column is comprised of core bar and loop bar, is two joint telescopic structures, and core bar upper end is by being welded with adapter sleeve, and core bar is sleeved on the two ends of crossbeam by adapter sleeve, and locates by jackscrew; Core bar hypomere is inserted in loop bar, has corresponding adjustment hole on core bar and loop bar, and core bar and loop bar are fastening by bolt and adjustment hole location; Leg middle part is fixed by welding in the bottom of loop bar; Leg is provided with row's fixed via.
Further, described derricking gear is self-locking type hand-operated capstan winch, bottle gouard moved by hands or electric block.
The utility model has the advantages that: simple in structure, volume is little, lightweight, with low cost, adopt dismantled and assembled structure design, be convenient for carrying and transport; At Overhaul site, can and be fixed on load ratio bridging switch body skin according to the model quick adjustment crossbeam span of on-load tap changers of transformers and height, lifting is stable, has effectively improved work efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In figure: 1, crossbeam, 2, orienting sleeve, 3, derricking gear, 4, adapter sleeve, 5, core bar, 6, loop bar, 7, leg.
Embodiment
As can be seen from Figure 1, the utility model comprises crossbeam 1, two root posts, leg 7 and derricking gear 3; Described derricking gear 3 can be according to treating docking facility selection self-locking type hand-operated capstan winch, bottle gouard moved by hands or electric block, derricking gear in the present embodiment adopts self-locking type hand-operated capstan winch, self-locking type hand-operated capstan winch is bolted on orienting sleeve 2 belows, and orienting sleeve 2 is sleeved on the stage casing of crossbeam 1; Orienting sleeve 2 can move along crossbeam 1, drives the motion of self-locking type hand-operated capstan winch to adjust position, Heave Here, and by the fastening location of jackscrew; On capstan winch, installed around lifting rope, lifting rope end connecting shackle;
Column is comprised of core bar 5 and loop bar 6, is two joint telescopic structures, according to the length of sling height adjusting post (being horizontal depth of beam); Core bar 5 upper ends are by being welded with adapter sleeve 4, the core bar 5 of two root posts is set in the two ends of crossbeam 1 by adapter sleeve 4, according to the size mobile link cover 4 of on-load tap changers of transformers, it is slided along crossbeam, adjust the spacing (being the span of crossbeam) of two columns, and by jackscrew, locate fastening; Core bar 5 hypomeres are inserted into loop bar 6 inside, and on core bar 5 and loop bar 6, correspondence has one and teases and ridicule knothole, and bolt is also fastening by core bar 5 and loop bar 6 location through adjustment hole; Leg 7 middle parts are fixed by welding in the bottom of loop bar, and leg 7 is provided with row's fixed via, for being connected and fixed with the body skin of on-load tap changers of transformers.
During use, first according to the size of on-load tap changers of transformers equipment to be keeped in repair, regulate span and the height of crossbeam; Utilize the screw of load ratio bridging switch apparatus casing upper surface, by bolt, will on leg 7, be fixed on switchgear housing top, the shell of the utility model lifter and load ratio bridging switch equipment is connected as a single entity, adjust the position of capstan winch and pass through the fastening location of jackscrew, make the suspension hook of self-locking type hand-operated capstan winch be positioned at load ratio bridging switch equipment core body directly over, core body is lifted on the lifting rope of self-locking type hand-operated capstan winch, shakes capstan winch handle and complete lifting operation.Because lifter and the shell of load ratio bridging switch equipment to be keeped in repair are fixed together, its Heave Here (capstan winch) and equipment to be repaired are without relative displacement, therefore in whole lifting process, the core body of switchgear realizes fast, vertical, pulsation-free is sling, and avoided core body slightly to swing and inner walls collision damage.
Finally should be noted that: above embodiment is used for illustrating that the technical solution of the utility model is not intended to limit; those skilled in the art modifies to embodiment or part technical characterictic is equal to replacement; and do not depart from the essence of technical solutions of the utility model, within all should being encompassed in the utility model scope required for protection.
