Abstract
The utility model discloses a spring stretching tool used for electric power construction, comprising clamping plates at two ends of a spring; wherein the each clamping plate is connected with one end of the spring through a large-headed bolt, the large-headed bolt is fastened by a nut after passing through the clamping plate; hydraulic jacks used for adjusting the length of the spring are arranged between the two clamping plates, two ends of the hydraulic jack are respectively fixed to the upper clamping plate and the lower clamping plate; and the two hydraulic jacks are symmetrically arranged at two sides of the spring between the two clamping plates. By adopting the above technical scheme, the spring stretching tool of the utility model has the advantages as follows: the large-headed bolt is clamped into one end of the spring, then the clamping plate is fastened with the large-headed bolt, and the spring is controlled and adjusted by operating the hydraulic jacks, thereby greatly raising reliability for controlling an energy storage spring, raising installation success rate and efficiency, and greatly raising safety; different models of large-headed bolts can be adopted to adapt to uses of springs with different diameters in different models of spring mechanisms; in addition, the spring stretching tool has a simple structure, and the selected material is easy to buy and has a low price, thus the spring stretching tool of the utility model is suitable for being popularized widely.
Description
Technical field
The utility model belongs to the electric construction tool technical field, particularly a kind of spring stretching tool used for power construction.
Background technology
At present, in the construction of the supporting spring mechanism of examination and repair for high-pressure circuit breaker because energy-stored spring hardness is large, and job site
There is not professional stretching tool.In case during the energy-stored spring long-play, the fixing screw at the energy-stored spring two ends energy-stored spring that gets loose
After coming off, cause energy-stored spring that difficulty is installed, hand operation is easily hurted sb.'s feelings.Process for on-the-spot high-voltage breaker mechanism failure accident
Increased difficulty.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of spring stretching tool used for power construction is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spring stretching tool used for power construction, it comprises the clamp of both ends of the spring, and clamp is connected with spring one end by stud bolt, and stud bolt uses nut fastening after passing clamp, and the hydraulic jack of adjusting spring length is set between two clamps.
Above-mentioned spring stretching tool used for power construction, the two ends of hydraulic jack are separately fixed on clamp and the lower clamp, are symmetrically arranged with two hydraulic jack between two clamps of spring both sides.
Adopt technique scheme, the utility model has following advantage: stud bolt is sticked into spring one end, again that clamp and stud bolt is fastening, by the operation hydraulic jack spring there is regulating and controlling, greatly increased the reliability to energy-stored spring control, increased success rate and the efficient of installing, and fail safe improves greatly.Stud bolt of the present utility model can adopt different model, with the spring use of applicable different model spring mechanism different-diameter.The utility model is simple in structure, and the easy purchase of the material of choosing and price are not high, are fit to generally promote.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of spring stretching tool used for power construction as shown in Figure 1, it comprises the clamp of both ends of the spring, upper clamp 2 is connected with spring 3 one ends by stud bolt 1, stud bolt 3 uses nut fastening after passing clamp, the hydraulic jack 4 of adjusting spring length is set between two clamps, two hydraulic jack are symmetricly set between two clamps of spring both sides, and the two ends of hydraulic jack 4 are fixed on upper clamp 2 and the lower clamp 5 by stud bolt respectively.Hydraulic jack can guarantee spring is realized stretching, and can guarantee two ends fixing hole and mechanism's fixing hole consistent size, is convenient to install.
