Abstract
The utility model discloses a spring controller in power construction. The spring controller comprises clamp rods on two ends of a spring, lead screws passing through the clamp rods and connecting with the clamp rods by threads, and pull rings disposed on two ends of the spring. The spring controller is simple in structure, convenient in operation, and high in operation reliability.
Description
Technical field
The utility model belongs to power construction utensil field, specifically a kind of controller of power construction medi-spring.
Background technology
In mechanism's construction of the supporting spring of examination and repair for high-pressure circuit breaker, because energy-stored spring hardness is large, and the job site does not have professional stretching tool.In case during the energy-stored spring long-play, fixedly the screw at energy-stored spring two ends easily gets loose, after causing energy-stored spring to come off, cause energy-stored spring that difficulty is installed, and hand operation is large due to the tension force of spring, easily hurts sb.'s feelings.Process for on-the-spot high-voltage breaker mechanism failure accident and increased difficulty, in prior art, take to adjust spring length in a positive flexible leading screw and the method that the flexible leading screw of anti-silk arranges flexible leading screw adjustment point, but the method is comparatively required great effort in practical operation because the arm of force is shorter.
The utility model has carried out useful improvement in order to overcome defects.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of controller of power construction medi-spring is provided.
The technical solution of the utility model is achieved in that the controller of this power construction medi-spring comprises the kelly of both ends of the spring, the leading screw that passes kelly and be threaded connection with kelly.
Further, described both ends of the spring is provided with draw ring.
Further, described leading screw upper end is provided with holder, offers a hole on holder.
Further, described holder is provided with a spanner, and spanner passes the hole on holder.
The beneficial effects of the utility model: the utility model is simple in structure, convenient operation, and functional reliability is high.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1-1. draw ring; 1-2. draw ring; 2. holder; 3. spanner; 4-1. kelly; 4-2. kelly; 5-1. leading screw; 5-2. leading screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1, the utility model provides a kind of controller of power construction medi-spring, the controller of this power construction medi-spring comprises the kelly (4-1,4-2) of both ends of the spring, kelly is used for the two ends of fixing spring, the leading screw that passes kelly and be threaded connection with kelly (5-1,5-2).
Described both ends of the spring is provided with draw ring (1-1,1-2), can be used for fixing spring when spring is stretched.
The upper end of leading screw is provided with holder (2), and holder is offered a hole on (2), and a spanner passes wherein, when needs stretching or restoring spring, can move spanner and make leading screw rotation, move up and down thereby drive kelly, not only laborsaving but also improved the fail safe in the operation.
The above execution mode has only been expressed a kind of execution mode of the present utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
