Abstract
The utility model discloses a dedicated tool for replacing an outdoor 35KVPT fuse, which comprises a buckle rope, a fixed boom, a movable boom, an auxiliary frame, a spindle, a main frame and a trigger, wherein the auxiliary frame is connected with the main frame through connecting bolts, and a tooth positioning leg and a tooth propelling leg are arranged inside the main frame; the tooth positioning leg is connected with the main frame through a through pin, and the tooth propelling leg is connected with the trigger through the through pin; a spindle tooth surface is arranged on the spindle, and when the trigger is pulled, the tooth propelling leg is tightly combined with the spindle tooth surface under the action of a tooth propelling leg pressure spring and propels the spindle to move ahead; and after the spindle moves ahead at an angle, under the action of a tooth positioning leg pressure spring, the tooth positioning leg and the spindle tooth surface utilize the barb principle to prevent the spindle from sliding backwards. The dedicated tool utilizes the reaction principle of tensile force to suppress the reaction force of the springs, can tightly fix an end cover of the fuse, effectively solves the problem that the tool can not be assembled with components well due to the spring force, greatly shortens replacement time, and improves work efficiency.
Description
Technical field
The utility model relates to a kind of dismounting specific purpose tool, particularly relates to a kind of specific purpose tool of outdoor 35KVPT change of fuse, belongs to transformer station fuse dismounting field.
Background technology
When changing, because of the reaction force of built-in spring, cause outer end cap mounting or dismounting difficulty after the outdoor 35KVPT fuse blows of present China transformer station, work high above the ground position limitation is strong during simultaneously owing to personnel operation, causes the replacing overlong time, has strengthened hazards.Power supply department had been formulated power supply reliability, protection action rate in recent years, the error measure that reduces to measure, and relevant departments often examine the outdoor used time of 35KVPT fuse of changing especially.At present according to changing the statistics investigation of used time of fuse, change a PT fuse and all surpassed the power supply department official hour used average time.
The utility model content
Technical problem to be solved in the utility model is: change the problem that work difficulty is big, the replacing time is long after solving fuse blows of the outdoor high pressure P T of transformer station, a kind of outdoor 35KVPT change of fuse specific purpose tool is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of outdoor 35KVPT change of fuse specific purpose tool, contain the button rope, decide arm, swing arm, sub-frame, main shaft, body frame and trigger, link to each other by connecting bolt between described sub-frame and the body frame, described body frame inside is provided with decides the tooth pin and advances the tooth pin, decide to link to each other with wearing pin between tooth pin and the body frame, advance between tooth pin and the trigger and link to each other with wearing pin; Described main shaft is provided with the main shaft flank of tooth, advancing the tooth pin during cocking combines closely with the main shaft flank of tooth advancing under the effect of tooth pin stage clip, and the promotion main shaft moves ahead, main shaft advances after the angle under the effect of decide tooth pin stage clip, makes and decides to utilize between the tooth pin and the main shaft flank of tooth hangnail principle prevention main shaft to slide backward.
Link to each other with wearing pin between described swing arm and the sub-frame, describedly decide to link to each other with bolt between arm and the body frame.
Described button rope is fixed on decides the arm front end.
The beneficial effects of the utility model are:
1, outdoor 35KVPT change of fuse specific purpose tool of the present utility model, the reaction force that suppresses spring by the principle of reaction of utilizing pulling force, the end cap of fuse can be fixed, effectively controlled because the problem that is not easy to assembly between spring force and the components and parts, shorten the replacing time greatly, improved operating efficiency.
2, outdoor 35KVPT change of fuse specific purpose tool of the present utility model, volume is little, and cost is low, not only is easy to carry, and also easy to install and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure section figure of the body frame inside described in Fig. 1;
