Abstract
The invention discloses a kind of spring stretching device, comprise base (1), be arranged on two support bars (2) on base (1), be arranged on the stretching screw rod (3) at base (1) middle part, drawing godet (4) and the two ends that are enclosed within on stretching screw rod (3) are arranged on the flexible strand (5) on drawing godet (4), described stretching screw rod (3) top arranges nut (6), and described support bar (2) top arranges fixed bar (7). The invention has the beneficial effects as follows: the spring on detaching equipment easily, and also simple in structure, good economy performance, easy to operate.
Description
Technical field
The present invention relates to a kind of spring stretching device.
Background technology
The operating mechanism of large electric switch generally need to use spring to provide energy for its quick acting, spring on equipment generally in extended state, if desired dismantling spring safeguards equipment, because of working space limited, large-scale hydraulic test can not use, because spring retraction force is large, only depend on artificial strength to be difficult to spring to pull open again.
Summary of the invention
The object of this invention is to provide a kind of spring stretching device, be convenient to the spring on equipment to remove.
For addressing the above problem, the technical solution used in the present invention is:
A kind of spring stretching device, comprise base, be arranged on two support bars on base, be arranged on the stretching screw rod at base middle part, drawing godet and the two ends that are enclosed within on stretching screw rod are arranged on the flexible strand on drawing godet, described stretching screw rod top arranges nut, and described support bar top arranges fixed bar. Fixed bar is fixing for this device, catches on the hook of the end of spring, rotating nut by flexible strand, its bottom to stretching screw rod is moved, drawing godet is pushed away downwards, flexible strand is tightened the rear hook to spring and is stretched, and the hook of spring is loosening, and be finally removed. The present invention sets about from the hook of spring end, has solved the trouble of spring retraction, has also saved manpower.
As a further improvement on the present invention, described fixed bar is fixed on support bar top setting. Fixed bar and support bar fix, and prevent that support bar from rotating around fixed bar.
As a further improvement on the present invention, described drawing godet two ends have the gap matching with the bar that stretches. Gap is set on drawing godet, matches with stretching bar, prevent that drawing godet from rotating around stretching screw rod in drawing process, flexible strand just can not be wound around, and facilitates reusing of device.
Further improve as of the present invention, described stretching screw rod is bolt, on described base, has bolt hole, and bolt is through bolt hole, and described nut and drawing godet are positioned on the bolt of base upper section. Bolt is standard component, is convenient for changing, and easily obtains, cheap, good economy performance.
In sum, the invention has the beneficial effects as follows: the spring on detaching equipment easily, and also simple in structure, good economy performance, easy to operate.
Brief description of the drawings
Fig. 1 is structural scheme of mechanism of the present invention.
Fig. 2 is the structural representation of drawing godet in reflection the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Spring stretching device as described in Figure 1, comprise base 1, be arranged on two support bars 2 on base 1, the stretching screw rod 3 that is arranged on base 1 middle part, drawing godet 4 and the two ends that are enclosed within on stretching screw rod 3 be arranged on the flexible strand 5 on drawing godet 4, described stretching screw rod 3 tops arrange nut 6, described support bar 2 tops are fixedly installed fixed bar 7, and described drawing godet 4 two ends have the gap 8 matching with the bar that stretches.
Foregoing stretching screw rod 3 is bolts, on described base 1, have bolt hole, bolt is through bolt hole, described nut 6 is positioned on the bolt of base 1 upper section with drawing godet 4, base 1 is that three nuts are side by side " one " font and weld together formation, two support bars 2 and fixed bar 7 are all screw rods, a nut of two each welding in support bar 2 tops, and the screw conllinear of two nuts and being horizontally disposed with, and the nut of suitable quantity is set on fixed bar 7, and foregoing flexible strand 5 is steel wires.
When use, tighten the nut on fixed bar 7, support bar 2 can not rotated around fixed bar 7, and fixed bar is fixed in place, then just steel wire catches on the hook of spring end, circumgyration stretch screw rod 3(bolt) head, there is relative displacement in make to stretch screw rod 3 and base 1, promoting drawing godet 4 moves to base 1 direction, steel wire is stretched and tightens gradually by the state that becomes flexible, until pull spring carrier arm and make spring carrier arm loosening, and finally unload whole spring.
In technical scheme of the present invention; all be not specifically noted; be prior art or can realize the technical program by the conventional means in this area; and should be understood that; for those of ordinary skills; can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
