Abstract
The utility model relates to a connecting rod for high-voltage circuit breaker operating mechanism to adjust clearance between open contacts and contact range, which comprises an adjusting sleeve at the center of the connecting rod, a hexagon head on outer wall of the adjusting sleeve and two sections of screw on inner wall of the adjusting sleeve. Wherein, one section of screw is plus and the other section of screw is minus. The plus thread and minus thread are respectively connected with a connecting screw rod. External end of the connecting screw rod is provided with a mounting hole. Two screw holes are positioned on the wall of the adjusting sleeve for fastening bolts. The utility model has the advantages that: The connecting rod is utilized to adjust clearance between open contacts and contact range to shorten the debugging time of such a working procedure from one hour in the past to ten minutes at present, reduce circuit breaker production and debugging time and spare part processing volume and greatly increase circuit breaker production efficiency.
Description
Technical field
The utility model relates in a kind of high-voltage breaker operation mechanism adjusting opens the connecting rod that distance and contacting travel are used.
Background technology
At present, in the operating mechanism of ac hv breaker, the brace of opening distance and contacting travel that is used to adjust between the circuit breaker dynamic/static contact is a kind of brace of fixed dimension.What need different size opens distance and contacting travel, fixedly connected of will change the different length size.In the middle of real work, often need installation and removal several times, just can adjust and open distance and contacting travel between dynamic/static contact, simultaneously, also to be equipped with fixedly connected of multiple length dimension.Use this fixedly connected to adjust and open distance and contacting travel between dynamic/static contact, not only operating efficiency is very low, and can not realize the required continuous adjusting of opening distance and contacting travel numeric dimensions.Thereby, strengthened the waste with spare part of taking that circuit breaker is produced debug time, reduced production work efficient.
Summary of the invention
The purpose of this utility model provides a kind of connecting rod that is used for high-voltage breaker operation mechanism that solves the prior art problem.
A kind of connecting rod that is used for high-voltage breaker operation mechanism, it is characterized in that: the mid portion of this connecting rod has an adjusting sleeve pipe, on the outer tube wall of regulating sleeve pipe, one six square toes are arranged, on the inner tubal wall of regulating sleeve pipe, have two sections screw threads, one section is plus thread, one section is left-hand thread, is screwed with the connection screw rod respectively on positive and negative two sections screw threads, and the outer end that connects screw rod is provided with installing hole respectively; On the tube wall of regulating sleeve pipe, have two screws, be screwed with trip bolt above.
The utility model has the advantages that: that uses that the connecting rod of the utility model structure adjusts circuit breaker opens distance and contacting travel size, make the debug time of this operation, by about a hour of past, be reduced to about present ten minutes, reduce circuit breaker and produced the processing capacity with spare part of taking of debug time, greatly improved the production work efficient of circuit breaker.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of connecting rod that is used for high-voltage breaker operation mechanism, it is characterized in that: the mid portion of this connecting rod has an adjusting sleeve pipe 1, on the outer tube wall of regulating sleeve pipe 1, one six square toes 2 are arranged, on the inner tubal wall of regulating sleeve pipe 1, have two sections screw threads, one section is plus thread, one section is left-hand thread, is screwed with respectively to connect screw rod 3 and connect screw rod 4 on positive and negative two sections screw threads, connects screw rod 3 and is provided with installing hole 5 and installing hole 6 respectively with the outer end that connects screw rod 4; On the tube wall of regulating sleeve pipe 1, have two screws 7 and 8, be screwed with trip bolt 9 and 10 above.
The profile that described connection screw rod 3 and connection screw rod 4 have an end of installing hole is a flat shape, and installing hole 5 on it and installing hole 6 are perpendicular with the screw rod of himself respectively.
The profile that described connection screw rod 3 and connection screw rod 4 have an end of installing hole is a mortar board shape, and installing hole 5 on it and installing hole 6 are perpendicular with the screw rod of himself respectively.
The profile that described connection screw rod 3 and connection screw rod 4 have an end of installing hole is cylindrical, and installing hole 5 on it and installing hole 6 are perpendicular with the screw rod of himself respectively.
The profile of described adjusting sleeve pipe 1 is cylindrical.
The profile of described adjusting sleeve pipe 1 is the hexagonal cylindricality.
Using method of the present utility model is: alignd in the hole of the main shaft connecting lever in the installing hole 5 and the breaker operation mechanism that connect in the connecting rod on the screw rod 3, and connect with bearing pin.Then, alignd in the hole of the transmission crank arm in the installing hole 6 on the connection screw rod 4 in the connecting rod and the breaker operation mechanism again, and connect with bearing pin.In the process of opening distance and contacting travel size of debugging dynamic/static contact, as long as six square toes 2 that turn slightly on the connecting rod make it to drive 1 rotation of adjusting sleeve pipe, can make to connect screw rod 3 and connect screw rod 4 and stretch out or indentation with respect to regulating sleeve pipe 1, thereby changed the overall length of connecting rod, realized opening the increase of distance and contacting travel size or reducing.After adjusting end, tighten trip bolt 9 and the trip bolt 10 regulated on the sleeve pipe 1.
