After transmission of electricity is the electric energy boosting for generator being sent with transformer, then through control devices such as breakers access power transmission line
Road is realized.By structure type, transmission line of electricity is divided into overhead transmission line and cable run.Overhead transmission line route route lever
The compositions such as tower, conducting wire, insulator, line hardware, bracing wire, pole and tower foundation, earthing or grounding means, are erected on ground.According to conveying
The property of electric current, transmission of electricity are divided into ac transmission and direct current transportation.The eighties in 19th century successfully realizes direct current transportation first.But
Since the voltage of direct current transportation is difficult to continue to improve under technical conditions at that time, so that ability to transmit electricity and benefit are restricted.19
The end of the century, direct current transportation are progressively replaced by ac transmission.The success of ac transmission has welcome the new of 20th century electrified society
Epoch.
The harsh weather such as strong wind heavy snow, frosting of freezing can cause the suitable bad of transmission line of electricity, greatly reduce transmission line of electricity
Service life, cause economically it is huge along lose.Be mostly among these because strong wind to power transmission line involve and freezes frost increase
The weight of transmission line of electricity causes pulling apart for transmission line of electricity.Existing shaft tower has certain pre-control for the tensile force of transmission line of electricity,
But often just lose effect in the case of some extreme weathers occur.
The content of the invention
The technical problem to be solved by the present invention is to：In order to solve the problems, such as present in above-mentioned background technology, to provide a kind of electricity
Power technological service power transmission line tensioning frame, solves that existing electric power line pole tower is too small to power transmission line tensile force control range to ask
Topic.
The technical solution adopted by the present invention to solve the technical problems is：A kind of power technology service is tensioned with power transmission line
Frame, including tensioning frame body, the tensioning frame body includes crossbeam, fixed frame and bracket, and the crossbeam is fixedly connected on
Fixed frame top, the crossbeam both ends are respectively fixedly connected with insulator string, and the sub- bottom of the insulator string is fixed to be connected
It connects there are one guide wheel, the fixed frame bottom is fixedly connected with bracket, and the bracket is fixedly connected with puller system one end, described
The puller system other end be fixedly connected with a guide wheel, the crossbeam puts up " big " word shape, the insulator string with fixation
Son is made of three insulation components, and a plurality of bolts and gasket have been respectively fixedly connected on the crossbeam and fixed frame；And
Tight frame body is in integrally symmetrical structure.
Preferably, the bolt and number of pads are 6.
Preferably, the crossbeam, fixed frame and bracket are made of angle steel.
Preferably, the elastic force apparatus is spring.
Preferably, the guide wheel is made of PVC material.
Preferably, the bracket is inversion " people " font.
The invention has the advantages that a kind of power technology service power transmission line tensioning frame of the present invention, is led by setting
The devices such as wheel, elastic force apparatus, bracket realize tensioning frame to the large range of control of cable tensile force, avoid bad weather pair
The destruction of cable and shaft tower improves the service life of transmission line of electricity, greatly reduces the maintenance cost of transmission line of electricity.
