Abstract
The invention discloses a spring stretching device. The spring stretching device comprises a base (1), two supporting rods (2) which are arranged on the base (1), a stretching threaded rod (3) which is arranged in the middle of the base (1), a stretching disc (4) which is sleeved on the stretching threaded rod (3) and a flexible rope (5), wherein the two ends of the flexible rope (5) are arranged on the stretching disc (4), the top portion of the stretching threaded rod (3) is provided with a nut (6), and the top portions of the supporting rods (2) are provided with fixing rods (7). The spring stretching device has the advantages that a spring on the device can be dismantled conveniently, the structure is simple, economical efficiency is good and operation is convenient.
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 use spring to provide energy for its quick acting, spring generally is in extended state on equipment, if needing the dismounting spring safeguards equipment, because of working space limited, large-scale hydraulic test can not use, because the spring retraction force is big, only depend on artificial strength to be difficult to spring is drawn back again.
Summary of the invention
The purpose of this invention is to provide a kind of spring stretching device, be convenient to the spring on the equipment is removed.
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 the base, be arranged on the base middle part the stretching screw rod, be enclosed within drawing godet on the stretching screw rod and two ends and be arranged on flexible strand on the drawing godet, described stretching screw rod top arranges nut, and described support bar top arranges fixed bar.Fixed bar is used for the fixing of this device, catches on the hook of the end of spring with flexible strand, the rotation nut, its bottom to the stretching screw rod is moved, drawing godet is pushed away downwards, the hook to spring after flexible strand is tightened stretches, and the hook of spring is loosening, and finally be 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 the 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 that matches with the bar that stretches.Gap is set on the drawing godet, matches with the stretching bar, prevent that drawing godet from rotating around the stretching screw rod in drawing process, flexible strand just can not twined, and makes things convenient for reusing of device.
Further improve as of the present invention, described stretching screw rod is bolt, has bolt hole on the described base, and bolt passes 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 obtains easily, and is cheap, good economy performance.
In sum, the invention has the beneficial effects as follows: the spring on the dismounting equipment easily, and also simple in structure, good economy performance, easy to operate.
Description of drawings
Fig. 1 is structural scheme of mechanism of the present invention.
Fig. 2 is the structural representation of drawing godet among reflection the present invention.
The specific embodiment
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 the base 1, be arranged on base 1 middle part stretching screw rod 3, be enclosed within drawing godet 4 on the stretching screw rod 3 and two ends and be arranged on flexible strand 5 on the drawing godet 4, described stretching screw rod 3 tops arrange nut 6, described support bar 2 tops fixedly install fixed bar 7, and described drawing godet 4 two ends have the gap 8 that matches with the bar that stretches.
Foregoing stretching screw rod 3 is bolts, have bolt hole on the described base 1, bolt passes 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 " one " font side by side and weld together formation, two support bars 2 and fixed bar 7 all are screw rods, a nut is respectively welded at two 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 the fixed bar 7, and foregoing flexible strand 5 is steel wires.
Tighten the nut on the fixed bar 7 during use, support bar 2 can not rotated around fixed bar 7, and it is fixed bar is fixing in place, just steel wire catches on the hook of spring end, circumgyration stretch screw rod 3(bolt then) head, make stretching screw rod 3 and base 1 that relative displacement take place, promoting drawing godet 4 moves to base 1 direction, steel wire is stretched gradually by loosening state and tightens, and until the pulling spring carrier arm and make spring carrier arm loosening, and finally unloads 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 conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
