Description
Technical field
The utility model is related to power grid construction technical field, more particularly, to a kind of power circuit crossing frame block structure.
Background technology
At present, power circuit crossing frame block structure has rigid structure block, synthetic material block, soft rope flexibility block etc.
Form.
1）Rigid structure binds：The biggest factor depended on runs all kinds of frame bodies of goal construction and overhead outside for high ferro
Whether horizontal distance requirement and railway department allow steelframe to be located at for a long time above railway.It is wide with the force that Hunan send power transformation to cross over
Exemplified by line, it is desirable that 17 meters of the distance on crossover device and rail top or more（It can be limited from wind speed caused by high ferro）.By current high speed
14.6 meters of railway width, if assuming, crossing frame and the outer lateral extent of high-speed railway are 3 meters（Crossover tower and the horizontal distance in overhead outside
It is unknown）, that is entirely 21.2 meters across the clear span of locking device.It is such as crossed over using rigid structure, can be one across girder steel
Big component, total quality is big, and it is big to install the difficulty of girder steel, and risk is high, while stringing is caught once broken string occurs, and conducting wire falls firm
It is possible that bounce on property ceiling.
2）Synthetic material binds：It is same as above across spacing, synthetic material currently on the market, more than 20 meters of distance need to be crossed over,
It is difficult to find that.Synthetic material have higher tension or compression strength, because structure inertia square and modulus are smaller, cause its rigidity without
Method is met the requirements.
3）Soft rope flexibility binds：The method is commonly used in existing construction, and is widely used in the leap of cableway block
Scheme.Soft rope is frequently with steel wire rope, steel strand wires, Di Nima ropes, South Korea's silk, industrial yarn etc..By the importance of leap, stress work
Condition, insulating requirements are respectively adopted.The method advantage is to limit from across spacing, can arbitrarily be adjusted reuse.It compiles
It is easy for construction when net and installation.As long as nettle intensity is enough, it is ensured that broken string operating mode, but the phenomenon of being caught that breaks easily occurs.
The content of the invention

It puts device to set with the second drawing draw off gear mirror symmetry, the first block bar and the second block bar
When being moved to lowest order, the first block bar mutually abuts with the second block bar and is linked to be straight line.
Described first drawing draw off gear includes the first fixed pulley, the first movable pulley and the first pulling rope, and described the
One fixed pulley is fixed on described first across the top of column, and first movable pulley is located at described first across the outer of column
Side, one end of first pulling rope are fixed on described first across at a certain distance from the outside of column and its other end and institute
The the first block bar stated is fixedly connected, and first pulling rope is successively around the bottom of first movable pulley and described
The top of first fixed pulley.
Described second drawing draw off gear includes the second fixed pulley, the second movable pulley and the second pulling rope, and described the
Two fixed pulleys are fixed on described second across the top of column, and second movable pulley is located at described second across the outer of column
Side, one end of second pulling rope are fixed on described second across at a certain distance from the outside of column and its other end and institute
The the second block bar stated is fixedly connected, and second pulling rope is successively around the bottom of second movable pulley and described
The top of second fixed pulley.
Compared with prior art, the utility model has the advantage of：A kind of power circuit crossing frame block of the utility model
Structure, in the case where pulling draw off gear effect, block bar is rotated along across column, can be realized automatic lifting, be stretched, can meet circuit
Across security protection requirement.And construction method is simple, it is short across the block time；It is motor-driven, it flexibly, can be with horse when circuit is not constructed
On withdraw across locking device, it is safe.
