Description
Technical field
The utility model relates to a kind of fastening, connection, dismounting or clamping tools, charged fastener of particularly a kind of converting equipment cable clip bolt of being used for.
Background technology
Transformer station is the flow direction of voltage of transformation in the electric power system, acceptance and distribution electric energy, control electric power and the electric power facility of adjustment voltage, and it gets up through the grid contact of its transformer with each step voltage.Except transformer, the bus, metering and the control that also have numerous switchgear, compile electric current is with instrument transformer, lightning protection device, protective relaying device etc., is that lead couples together these equipment components in order and forms a power transformation system.Daily in service, the junction of connection device element can bolt looseness occur and cause heating, is commonly called as the wire clamp conductor joint heating.Wire clamp conductor joint heating main cause has overload, the outmoded joint oxidation of equipment, factors such as maintenance technology is not in place are installed makes bolt looseness or damage.Bolt looseness or damage can develop into conductor joint heating and vicious circle gradually, and the joint meltdown accident possibly take place severe patient.
The method of handling the wire clamp conductor joint heating generally is to adopt to have a power failure to handle or equipotential live line working processing.There is bigger shortcoming in these two kinds of operational methods, adopt power failure to handle the decline that will cause power supply reliability, if adopt equal potential working, often receive the device security distance and have very big security risk inadequately.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of safe, reliable, operates the practical charged fastener of converting equipment cable clip bolt.
The utility model is realized through following approach:
The charged fastener of converting equipment cable clip bolt includes sleeve, insulating bar, and its structural feature is; Also include a control device; This control device comprises the gear train of being made up of be parallel to each other engagement first gear and second gear, first gear include the connection axostylus axostyle with under be connected axostylus axostyle, second gear includes down the connection axostylus axostyle; Sleeve is connected going up of first gear and connects axostylus axostyle or connect axostylus axostyle down, and insulating bar is connected the following connection axostylus axostyle of second gear.
The device clamp of transformer station adopts the crimping mode usually, connect about two drainage plates have vertically and mode that level stacks up and down, for vertical left and right sides connected mode, promptly bolt wear about being to, utilize the routine work instrument to solve easily.But stack mode up and down for level, promptly bolt is worn to for from top to bottom or from bottom to top, difficulty very just, and the operating personnel is remote operation usually, thereby more difficult in the operation.The said fastener of the utility model has solved this problem: during operation; Insulating bar is connected the following connection axostylus axostyle of second gear; When the nut below the fastening wire clamp of needs; Can sleeve be installed in going up of first gear and connect on the axostylus axostyle, rotate insulating bar driven gear group and rotate, reach the fastening purpose of square nut down; When on the fastening wire clamp of needs during square nut, sleeve is changed to the following axostylus axostyle of first gear, rotate insulating bar driven gear group and rotate, reach the fastening purpose that goes up square nut.
Like this, for converting equipment cable clip bolt fastening just can the realization level stack up and down bolt wear to operation, and simple in structure, easy to operate, reliable, practical.
The utility model can further be specially:
The speed ratio of first gear and second gear is 2:1.
Like this, first gear is a gear wheel, and second gear is a pinion; Second gear connects insulating bar, is driving wheel, and first gear is a driven pulley; Branch sleeve, the speed ratio of two gears of size is 2:1, promptly driving wheel sends 1kgf; On driven pulley, can obtain 2kgf, thereby reach the labour-saving purpose.During use, rotate insulating bar, the power of sending from driving wheel drives driven pulley.Driven pulley is accepted the power from driving wheel, drives the nut in the sleeve adapter sleeve on the axle.
Also include magnet arrangement, it is installed on the sleeve.
Since the device clamp bolt all apart from ground more than 3 meters the height; The hand-held insulating bar that has gear train of operating personnel is faced upward the head operation on ground; If the gear train quality is big; To cause action bars to rock and be difficult to sleeve is inserted in nut, magnet arrangement can be inserted in bolt and nut by auxiliary socket, thereby realizes operation more easily.In addition, the said technical scheme of the utility model also can be used for realizing changing nut, and new nut is placed in the sleeve, adsorbs through magnet arrangement, new nut is installed to assigned address in the effect held of insulating bar then.
The anti-rotation bar is installed on the sleeve body.
When cable clip bolt generation transfer can't reach fastening effect or bolt get rusty when damaging, the anti-rotation bar can withstand wire clamp, prevents the bolt transfer.
In sum; The utility model provides a kind of converting equipment cable clip bolt charged fastener; Stack mode up and down for level on the wire clamp; Be bolt wear to for from top to bottom or bolt from bottom to top can reach good fastening effect, simple in structure, easy to operate, reliable, practical.
Description of drawings
Shown in Figure 1 is the structural representation of the charged fastener of the said converting equipment cable clip bolt of the utility model;
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Embodiment
Most preferred embodiment:
With reference to accompanying drawing 1; The charged fastener of converting equipment cable clip bolt; Include sleeve 1, insulating bar 2 and control device; This control device comprises the gear train of being made up of be parallel to each other engagement first gear 3 and second gear 4, first gear 3 include connection axostylus axostyle 31 with under be connected axostylus axostyle 32, the second gears 4 and include down connection axostylus axostyle 41; Sleeve 1 is connected going up of first gear 3 and connects axostylus axostyle 31 or connect axostylus axostyle 32 down, and insulating bar 2 is connected the following connection axostylus axostyle 41 of second gear 4 through a kind of universal joint 5.
Wherein the speed ratio of first gear 3 and second gear 4 is 2:1, and first gear is a gear wheel, and second gear is a pinion, is respectively driven pulley and driving wheel, to reach the labour-saving effect.As required, can develop fastening many ut sockets, this sleeve has the function of any one nut in many nut apparatus of difference fastening bolt mode.Fastening many nuts have the function of fastening diverse location nut respectively with long sleeve.When bolt adopted double nut to install, the order of clamp nut was the fastening again outer nut of the fastening inner nut of elder generation.When fastening inner nut, the processing long sleeve makes it not have thread with the outer nut contact portion and contacts; When fastening outer nut, the part that the processing long sleeve makes it to contact with inner nut does not have the thread contact.Through the sleeve of such development, can reach the function of any one nut in many nut apparatus of difference fastening bolt mode.
In addition, magnet arrangement and anti-rotation bar (function of the two adopts existing magnet suction twist preventing apparatus to realize) can also be installed on the sleeve, can utilize magnet suction to hold bolt, the anti-rotation bar withstands wire clamp, prevents the bolt transfer; Utilize the suction of magnet simultaneously, make sleeve hold bolt and remove or install the purpose that reaches the replacing bolt.
Except fastening effect, can also change bolt: utilize fastener to remove old bolt; New bolt is installed on the magnet suction twist preventing apparatus, bolt is inserted in the wire clamp hole again, utilize fastener with the nut screw rod of packing into, the nut of screwing reaches and changes the bolt purpose.
It is identical with prior art that the utility model is not stated part.
