Further, described base is provided with one group of long fixed orifice for connecting device housing.
The utility model has the advantages that: structure is simple, volume is little, lightweight, be convenient for carrying and transport, this device is directly fixed on load ratio bridging switch body skin, lifting operation is reliable and stable, this device controls the flexible of arm by arm regulating mechanism, and coordinate revolving structure to do 360 degree of rotations, considerably increase flexibility of operation, be convenient to the core body of load ratio bridging switch to move to best operational position, be applicable to the lifting of plurality of specifications on-load tap changers of transformers core body, reduce task difficulty and labour intensity, effectively improve work efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In figure: 1, orienting sleeve, 2, arm, 3, lifting pulley, 4, lifting rope, 5, suspension hook, 6, column, 7, swing type mechanism, 8, base, the 9, first turnbuckle, the 10, second turnbuckle, 11, stay cord, 12, fixed pulley.
Embodiment
As can be seen from Figure 1, the utility model comprises arm 2, column 6, base 8, orienting sleeve 1, swing type mechanism 7, derricking gear, arm regulating mechanism; Orienting sleeve 1 is horizontally fixed on column 6 top, and column 6 lower end is connected with base 8 by swing type mechanism 7, and described swing type mechanism 7 is made up of mutual sheathing mandrel together and sleeve, and mandrel, sleeve are fixedly connected with base 8 and column 6 respectively; Bearing fit (self-aligning thrust roller bearing can be adopted) is passed through between mandrel and sleeve.
This swing type mechanism 7 also according to circumstances can adopt pivoting support bearing (i.e. turntable bearing), can bear larger axial, Radial load and capsizing moment simultaneously.
Described base 8 is provided with one group of long fixed orifice for connecting valve apparatus casing.
The stage casing of arm 2 is inserted in orienting sleeve 1, arm 2 and orienting sleeve 1 bearing fit;
Described derricking gear and arm regulating mechanism lay respectively at the both sides of column 6; Derricking gear comprises the first turnbuckle 9 and two lifting pulley 3, first turnbuckles 9 are fixed on column 6 stage casing; Two lifting pulleys 3 are arranged on the epimere of the anterior lifting segment end of arm 2 and column 6 respectively; Lifting rope 4 walks around two lifting pulleys 3, and one end of lifting rope 4 is provided with suspension hook 5, and the other end is connected with the first turnbuckle 9;
Arm regulating mechanism comprises the second turnbuckle 10 being fixed on column 6 stage casing and the fixed pulley 12 being fixed on column 6 epimere, and fixed pulley 12 walked around by stay cord, and two ends are connected with the rear end of arm 1 and the second turnbuckle 10 of regulating mechanism respectively.
The first described turnbuckle 9 and the second turnbuckle 10 are the commercially available hand winch product with auto-lock function.
During use, first the screw above switchgear housing is utilized to be fixed by base 8, this lifting appliance is connected as a single entity with the shell of load ratio bridging switch equipment, regulate the position of arm 2, and make the lifting segment end of arm 2 (hanging position of suspension hook) be positioned at switchgear shell nozzle center, namely directly over load ratio bridging switch core body; Core body is connected with lifting rope, rotates capstan winch handle and complete lifting operation.
When after the complete separation instrumentation housing of load ratio bridging switch core body, rotate column 6 and core body is moved to shell nozzle side; Or according to field condition, tighten up stay cord by the second turnbuckle 10 handle, pull arm 2 that its lifting segment is stretched out (in figure right section of arm) further, the opening of housing is left in Heave Here; After having overhauled, slowly loosen the second turnbuckle 10 stay cord, reclaims (namely lifting segment shortens) due under the effect that core body deadweight makes arm 2 make a concerted effort at suspention section and the horizontal segment of the first turnbuckle lifting rope, until core body is positioned at directly over apparatus casing opening, stopping discharges stay cord; Then loosen the first turnbuckle lifting rope, make core body slowly enter housing.In above-mentioned lifting process, shunting switch core weight is carried by this device completely, because the shell of lifter and load ratio bridging switch equipment to be repaired is fixed together, its Heave Here (capstan winch) and equipment to be repaired are without relative displacement, therefore in whole lifting process, the core body realization of switchgear is quick, vertical, pulsation-free is sling, and avoids core body and slightly swings and inner walls collision damage.When should notice that arm 2 stretches in operation, core body position produces height change thereupon, need reserve surplus and prevent its damage of surprisingly contacting to earth.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to embodiment or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
