Detailed Description
The present invention will be described in further detail with reference to the following examples, but the scope of the present invention is not limited to the above description.
Example 1: as shown in fig. 1 and 2, the disassembly and assembly tool for the closing spring of the 35kV circuit breaker comprises a base 1, a supporting column 2 and a supporting plate 3, screw rod 4, gland nut 5, lifting nut 6, galvanized steel cable 7, base 1 is the square body, welded fastening has a columniform support column 2 on 2 individual bases 1 respectively, 3 welded fastening of backup pad are on 2 individual support columns 2 tops, backup pad 3 is the cuboid, it has I11 of internal screw thread hole to open in backup pad 3, screw rod 4 sets up in hole I11 and screw-thread fit, lifting nut 6 fixes in 4 upper ends of screw rod and lies in backup pad 3 tops, it has through-hole 8 to open on the 4 lower extremes of screw rod, 2 5 suits of gland nut are in 4 lower parts of screw rod and lie in 8 both sides of through-hole, gland nut 5's internal thread and 4 screw-thread fit of screw rod, 7 one end of galvanized steel cable is connected in waiting to demolish the spring preformed hole 10 at spring top, the other end is connected in 4's of screw rod through-hole 8 and.
As shown in fig. 3, the method of using the above device in the field is as follows:
the first step is as follows: before replacement, the breaker mechanism 12 needs to be adjusted to a brake-separating non-energy-storage state, and the breaker mechanism releases energy;
the second step is that: penetrating a galvanized steel rope 7 into a spring preformed hole 10 at the top of a closing energy storage spring of the circuit breaker, as shown in fig. 2;
the third step: then the galvanized steel rope 7 is penetrated out from a hole II 9 on the circuit breaker operating mechanism, the condition of the steel rope is checked in time before the steel rope is penetrated out, and if serious strand scattering and strand breaking conditions are found, the intact galvanized steel rope is replaced in time;
the fourth step: the galvanized steel rope 7 penetrates out of the hole II 9 and then penetrates out of a through hole 8 in the screw rod 4, and the galvanized steel rope 7 is tightly pressed by 2 compression nuts 5 on the screw rod 4; when the galvanized steel wire rope 7 penetrates into the through hole 8, the rope ends at the two ends adopt a pair penetrating mode, so that the screw rod is ensured not to be inclined when the screw rod is lifted;
the fifth step: the assembled screw rod 4 penetrates through a hole I11 in the supporting plate, a lifting nut 6 is assembled on the upper portion of the screw rod, the lifting nut 6 is rotated by a quick wrench, and the screw rod can be rotated to pull up the spring;
and a sixth step: in the lifting process of the screw rod 4, the lifting condition of a closing spring is concerned, and when the upper shaft pin is not stressed any more or becomes loose, the lifting process is stopped in time, and the shaft pin can be tried to be pushed out; in the process, the lifting height needs to be continuously adjusted, and the overstretch closing spring is switched off to cause the galvanized steel wire rope to be broken under stress, so that workers are accidentally injured;
the seventh step: after the upper shaft pin 13 is withdrawn, the spring is taken out from the energy storage rocker arm at the lower part, and when the spring is taken out from the energy storage rocker arm at the lower part, the closing energy storage spring at the inner side of the circuit breaker operating mechanism is difficult to avoid being blocked by the metal partition plate because the metal partition plate at the two sides has a relatively compact distance, at the moment, the circuit breaker energy storage rocker arm can be downwards rotated by using a pipe wrench or a special closing wrench, and when the circuit breaker energy storage rocker arm is rotated to be horizontal and close to the outer side, the closing spring is taken out without being blocked by the metal partition plate.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
