Abstract
An open-closed fixture for bearing insulators comprises two fixture limiting rods which are respectively screwed into the two sides of an open-closed fixture assembly. After the open-closed fixture assembly is opened, an insulator to be assembled is placed in the middle position of the open-closed fixture assembly. Then, the open-closed fixture assembly is closed and locked, and the insulator is buckled and prevented from falling off. Finally, the fixture limiting rods are respectively screwed into the two sides of the open-closed fixture assembly, and the open-closed fixture assembly and the insulator are positioned. The open-closed fixture has an overall bearing capacity of up to 40-60 tons, and can meet the requirement of the existing maximum 55-ton insulator string. The various requirements for adjustable distance during tightening and loosening can be met only by adopting long fixture limiting rods, and a large range of adjustable distance is achieved. The open-closed fixture of the invention has the advantages of simple structure, low cost and high versatility, and can match the existing insulator structure. The open-closed fixture is applicable to the field of bearing of various large-tonnage insulators.
Description
Technical field
The present invention relates to a kind of load-carrying apparatus, particularly relating to a kind of closed type fixture for carrying large-tonnage insulator weight.
Background technology
At present; the emergency maintenance of electric power system, the department of routine servicing often can come into contacts with insulator; insulator is made up of glass or pottery usually; insulator plays two basic roles in overhead transmission line; i.e. support wire and prevent electric current from going back to ground, these two effects must be guaranteed, and insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition; otherwise insulator would not produce effect, use and the service life of whole piece circuit will be damaged.
In power transmission and transformation system, insulator is usually made into insulator string and uses, and cause the weight tonnage straight line of insulator to rise, the weight of insulator string the heaviest under prior art can reach 55 tons, so the instrument of carrying insulator must have top load holding capacity, high strength and on-deformable requirement.
And generally have employed a kind of steel cap jig for what carry insulator, the defect that this steel cap jig exists due to technology and design under prior art, be difficult to the load bearing requirements meeting various insulator, its particular problem is as follows:
1. the carrying for the steel cap jig carrying insulator under prior art is stressed low, is generally only the bearing capacity of 5 ~ 10 tons, can only be used for the insulator of the lighter weight of old model, cannot be applied to novel heavier insulator;
2. the steel cap jig for carrying insulator under prior art, it is all steel plate that this steel cap jig is designed to both sides, then punch onboard, the steel plate of both sides is connected again with screw mandrel, finally form the jig of a steel hat shape, due to structural problem, screw mandrel+steel cap carrying causes low bearing capacity (insulator quality is directly oppressed on screw mandrel and steel cap), and the adjustable distance scope of the jig of the spacing steel hat shape causing steel plate to be formed of screw mandrel connection is very little, if distance adjustment crosses conference affect total bearing capacity, therefore its adjustable distance is designed to be only 10 ~ 20cm, and the model of insulator string is different, its size is also inconsistent, therefore cause discovery adjustable distance when using inadequate, be difficult to meet the demands.
In sum, existing in the urgent need to a kind of novel jig for carrying insulator, while accomplishing that larger carrying is stressed, also can obtain larger adjustable distance scope, can match with existing insulator structure, its versatility also will be guaranteed.
Summary of the invention
In order to solve the carrying insulator under prior art old-fashioned jig existing for stressed low, the structural design of carrying on problem cause the defect that adjustable distance scope is little, the invention provides a kind of open and close type jig carrying insulator, by the fixture structure redesigned, make to which give and compare old-fashioned jig more large-tonnage bearing capacity, and adjustable extent also expands thereupon, a kind of open and close type jig carrying insulator of the present invention, its concrete structure is as described below:
