Abstract
The invention relates to a tool for examining and repairing electrical equipment, in particular to a tool for replacing a spring of a circuit breaker. The tool comprises a leading screw and a nut matched with the leading screw, and is characterized in that: the nut is rectangular-plate-shaped; a positioning shaft penetrates through the rectangular-plate-shaped nut and a moving block of which the shape is the same as that of the rectangular-plate-shaped nut; one end of the leading screw is pressed against one side of the moving block, and a rotating handle is fixed at the other end of the leading screw; and a spring fixing block is arranged on the rectangular-plate-shaped nut corresponding to one side of the moving block. According to the technical scheme of the invention, the leading screw is used for changing rotary movement into linear movement of the moving block, the spring fixing block which is matched with the spring of the circuit breaker required to be dismounted is used for pushing off the spring in the circuit breaker to finish dismounting and mounting. The tool has the characteristics of reasonable structure and convenience for use, can effectively increase the spring replacement efficiency by more than 10 times, and the like.
Description
Technical field
The present invention relates to a kind of electric equipment service kit, particularly a kind of breaker spring is changed instrument.
Background technology
Fast development along with electric power; Present most of circuit breaker all adopts spring mechanism; Spring mechanism with its reliable in action, safeguard simple and the replacement liquid press mechanism; Use the back fatiguability for a long time but the weak point of spring mechanism is a spring, thereby cause circuit breaker branch, closing speed not to reach specification requirement, need to change spring.The circuit breaker of spring mechanism is because its compact layout causes spring replacing space narrow and small, and staff can't stretch into; Can't spring be elongated; Cause when changing working expenditure, effort, even if those of skill in the art change a spring also to a little 2-3 hours, unskilled personnel are just consuming time more; And can finger scuffing, extruding badly just take place, damage elements such as spring, axle sleeve sometimes.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of replacing spring rapidly, fast, breaker spring rational in infrastructure is changing device more.
For the technical scheme that realizes above-mentioned purpose is: a kind of breaker spring is changed instrument; Comprise leading screw and the nut that matches with leading screw; It is characterized in that nut is tabular with rectangle, locating shaft pass the tabular nut of rectangle with the identical movable block of the tabular nut shape of rectangle, an end of leading screw withstands on a side of movable block; The other end of leading screw is fixed with rotation and uses handle, at tabular nut of rectangle and the corresponding side of movable block the spring fixed block is installed.
Above-mentioned spring fixed block is tabular, has " C " shape opening above that.
Above-mentioned spring fixed block is that screw is connected or other removably connects with the installation form of tabular nut of rectangle and movable block.
The contact-making surface of above-mentioned leading screw and movable block is spherical.
Technical scheme of the present invention is to utilize the leading screw straight line that becomes movable block that will rotatablely move to move, and the spring fixed block through the breaker spring with the need dismounting matches struts the spring in the circuit breaker, is used for dismounting and installs.It is rational in infrastructure, easy to use that this device has, and can effectively improve spring and change 10 times of efficient with first-class characteristics.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the left view of accompanying drawing 1 of the present invention.
Embodiment
Like accompanying drawing 1, shown in 2; On the tabular nut 5 of the rectangle of right-hand member, associated leading screw 3 is installed; The movable block 1 identical with the tabular nut shape of rectangle arranged in the left side of the tabular nut of rectangle; Locating shaft 2 passes tabular nut of rectangle and movable block, and tabular nut of rectangle and movable block can be moved along the locating shaft straight line.The left end of leading screw withstands on the right flank of movable block, and for reducing the frictional resistance between leading screw and the movable block, the contact-making surface of leading screw and movable block is spherical.At tabular nut of rectangle and the corresponding upside of movable block spring fixed block 7 is installed; The spring fixed block is tabular; Have " C " shape opening above that; Be the spring in the circuit breaker that adapts to the dismounting different size, above-mentioned spring fixed block is that screw 8 is connected or other removably connects with the installation form of tabular nut of rectangle and movable block.
During use, " C " shape opening on the two spring fixed blocks is inserted in the spring 4, with handle 6 rotating threaded shafts, promote movable block by leading screw and move right, spring is strutted, can the spring in the circuit breaker be pulled down taking-up through the rotation on the leading screw.Identical with said process during installation, existing good spring inserts in " C " shape opening on the fixed block, and rotating threaded shaft struts spring and then the spring that struts is installed in the circuit breaker, and the reverse rotation leading screw takes out this device and gets final product.
