Abstract
The invention relates to a high-voltage cabinet stroke switch control device comprising a rotary shaft of a grounding switch and a collision block installed on the rotary shaft, wherein a groove is arranged on the outer wall of the rotary shaft, and the collision block is fixed on the rotary shaft by a fastener through a fastening screw hole. The high-voltage cabinet stroke switch control device is characterized in that a radially extended lug is arranged on the inner hole wall of the collision block, the shape of the lug is consistent with that of the groove, and the fastening screw hole extends to the end face of the lug. In the invention, since the lug is arranged on the inner hole wall of the collision block and the original fastening screw hole extends to the end face of the lug, the collision block can be firmly positioned on the rotary shaft by the lug embedded in the groove under the fastening of a fastening screw, and the working face of the collision block collides with the contact of a stroke switch so that the loosening phenomenon can not be caused between the collision block and the rotary shaft. In addition, after the working face of the original collision block is charged into a flat arc shape from a conical arc shape, the collision time of the collision block to the contact of the stroke switch is increased, thereby solving the problem of insufficient closure and opening display of the stroke switch.
Description
[technical field]
The invention belongs to a kind of high-voltage cabinet stroke switch control device, relate in particular to a kind of being installed in the high-voltage board, travel switch is started to control the device of making usefulness with the JN15 earthed switch.
[background technology]
The structure of existing JN15 earthed switch control travel switch as shown in Figure 1.The rotating shaft a of earthed switch is provided with a cam-type collision block g.During work, when rotating shaft a made left-hand or dextrad and rotates, the working face f that carries collision block g conflicted with the travel switch contact d that is installed in the one side, thus control travel switch deciliter.
There are the following problems for existing structure: 1, the endoporus of collision block g is a circular hole, has the section bar of a groove b and rotating shaft a is an outside wall surface, and collision block g is fixedly mounted on the outside wall surface of rotating shaft a through holding screw e.During operation, rotating shaft a drives collision block g and travel switch contact d conflicts, and it is loosening to cause holding screw e to produce easily, and therefore, collision block g can not be fixed on the rotating shaft a very reliably, and then influence is to the control of travel switch, poor reliability.2, the contacting travel of collision block g and travel switch contact d is too short, and it is not in place to cause travel switch to close branch easily, causes switch cubicle normally not show and whether closes branch.
[summary of the invention]
For overcoming the prior art above shortcomings, the present invention aims to provide a kind of high-voltage cabinet stroke switch control device, and it has effective control travel switch and closes branch, and the high advantage of reliability.
Realize that the above-mentioned purpose technical scheme is as follows, the structure of this high-voltage cabinet stroke switch control device, comprise the rotating shaft of earthed switch, and be installed in collision block in the rotating shaft, have a groove on the outer wall of rotating shaft, collision block is fixed in the rotating shaft through the trip bolt hole by securing member, it is characterized in that: have a radially-protruding projection on the inner hole wall of described collision block, the shape of described projection and the shape of described groove match, and the trip bolt hole extends to the end face of projection.
During concrete enforcement, the working face of described collision block is flat arcuation.
Beneficial effect: compared with prior art, the present invention is provided with projection on the inner hole wall of collision block, and make original trip bolt hole extend the projection end face, therefore, collision block relies on the projection be embedded in the described groove, trip bolt fastening down, can be positioned at very securely in the rotating shaft, make the conflict of collision block working face and travel switch contact, can not cause occurring between collision block and rotating shaft loosening phenomenon.In addition, with the working face of original collision block from the taper arcuation, make flat arcuation into after, increased collision block to the compressing the time of travel switch contact, thereby the branch that closes that has solved travel switch shows phenomenon not in place.
For deepening the understanding of the present invention, be described in further detail by embodiment below in conjunction with accompanying drawing.
[description of drawings]
The broken section structural representation of Fig. 1 prior art structure.
Fig. 2 is the broken section structural representation of one embodiment of the invention.
Among Fig. 1: rotating shaft a, groove b, travel switch c, contact d, trip bolt e, working face f, collision block g.
Among Fig. 2: installing rack 1, bent plate 2, rotating shaft 3, collision block 4, working face 41, projection 5, trip bolt 6, mounting bracket 7, travel switch 8, contact 81, fixture 9, waist hole 91.
[embodiment]
Referring to Fig. 1.Installing rack 1 is fixed on the inwall of high-voltage board, and bent plate 2 is fixed on the installing rack 1.The through hole that has admittance earthed switch rotating shaft 3 on the bent plate 2.Stretch out on the axle body of rotating shaft 3 of bent plate 2 through holes fixedly collision block 4, travel switch 8 is fixed on a side of rotating shaft 3 through mounting bracket 7, bent plate 2, and the contact 81 of travel switch 8 is positioned on the movement locus of collision block 4 working faces 41, by fixture 9 location.Admitting the screw of fixture 9 is waist hole 91, can change distance between travel switch 8 and the rotating shaft 3 by waist hole 91, thereby adjusts the conflict power between described collision block 4 working faces 41 and the contact 81, realization fine tuning.
Fixedly during collision block 4, the projection 5 on collision block 4 inwalls is embedded in the groove of rotating shaft 3, because the shape of projection 5 matches fully with the groove in the rotating shaft 3, both realize the close-fitting connection.Under the nut of trip bolt 6 in being embedded at collision block 4 grooves cooperates, the front end face of trip bolt 6 passes the screw of projection 5, directly be pressed on the groove diapire of rotating shaft 3, thereby very securely collision block 4 be fastened in the rotating shaft 3, loosening phenomenon occurs to avoid collision block 4.
For prolonging compressing the time between travel switch 8 contacts 81 and collision block 4 working faces 41, the branch that closes that solves travel switch shows phenomenon not in place, and the present invention has been modified into flat arcuation with described working face 41, makes both have the long time to contact.
