Abstract
The invention relates to overhaul tools of electrical equipment, in particular to a replacing device for springs of a breaker, which comprises a lead screw and a nut matched with the lead screw and is characterized in that the nut is fixed in the middle of a beam, two ends of the beam are connected with one ends of two connection rods through hinges I, and spring clamps are fixed at the other ends of the two connection rods. A U-shaped connection part is installed at the lower end of the lead screw in rotary mode, two sides of the U-shaped connection part symmetrical to the axis of the lead screw are respectively connected with one ends of the two connection rods through two hinges II, and the other ends of the two connection rods are connected with the spring clamps through hinges III. The technical scheme of the replacing device is that during rotation, the lead screw moves vertically to drive a planar connection rod mechanism to move, so that the spring clamps are driven to move relatively, and the springs in the breaker are spread for detaching and installing. The replacing device for the springs of the breaker has the advantages of being simple in structure, convenient to use, capable of effectively improving spring replacing 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 changing device more.
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 changing device more; Comprise leading screw and the nut that matches with leading screw; It is characterized in that nut is fixed on the middle part of crossbeam; The crossbeam two ends all link to each other with an end of two connecting rods through the hinge I, and the other end of two connecting rods all is fixed with spring perch, " U " shape connector are installed in that the leading screw lower end is rotatable; Both sides with leading screw axis symmetry on " U " shape connector link to each other with an end of two connecting rods respectively through two hinge II, and the other end of two connecting rods links to each other with spring perch through the hinge III.
Above-mentioned spring perch is " L " shape, and an end of one of them face and connecting rod is fixedly linked, and has down " U " shape groove on the another side.
Above-mentioned leading screw lower end and " U " shape connector rotatable is connected the internal thread opened by leading screw lower end edge leading screw axis and forms with the bolt that internal thread matches.
Technical scheme of the present invention is to utilize leading screw in the process of rotation, to move up and down, and drives planar linkage mechanism and moves, and relatively moves thereby drive spring perch, and the spring in the circuit breaker is strutted, and is used for dismounting and installation.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 A of accompanying drawing 1 of the present invention-A cutaway view;
Accompanying drawing 3 for the B of accompanying drawing 1 of the present invention to zoomed-in view.
Embodiment
Like accompanying drawing 1,2, shown in 3; Be fixed with nut 10 at the middle part of crossbeam 4; Leading screw 2 is installed in the nut; Leading screw top on the crossbeam is equipped with the handle 1 that is used for rotating threaded shaft, and its axis of the lower end edge of the leading screw under the crossbeam has internal thread, and " U " shape connector 11 is through the bolt 12 rotatable leading screw lower ends that are installed in.Right ends at crossbeam links to each other with the upper end of left and right sides connecting rod 5 through hinge I 3 respectively, and the lower end of two connecting rods all is fixed with spring perch 6.The left and right sides with leading screw axis symmetry on " U " shape connector links to each other with the upper end of two connecting rods 8 respectively through two hinge II 9, and two connecting rod lower ends link to each other with spring perch through the hinge III.Spring perch 6 is " L " shape, and the lower end of one of them face and connecting rod 5 is fixedly linked, and has down " U " shape groove on the another side.
When dismantling the spring in the circuit breaker, make it rise to the top as shown in Figure 1 the leading screw rotation, " U " shape groove in two spring perches 6 is inserted in the spring 7; The reverse rotation leading screw; Leading screw moves down, and drives " U " shape connector 11 downward straight lines and moves, and drives hinge I 3 rotations of connecting rod 5 along crossbeam 4 two ends through connecting rod 8; Spring is strutted, can the spring in the circuit breaker 7 be pulled down taking-up.Identical during installation with said process; Existing leading screw is rotated makes it rise to the top as shown in Figure 1; The spring that needs are changed is contained in " U " shape groove in two spring perches 6, and the reverse rotation leading screw struts spring; Then the spring that struts is installed in the circuit breaker, rotating threaded shaft takes out this device and gets final product.
