Big height difference grounded-line zero damages five skating cars, including sheath body and be separately positioned in sheath body positioned at the suspension centre coaster on upper layer, the movable block positioned at middle level, the hanging object coaster positioned at lower layer totally three layers of coaster；The suspension centre coaster for being wherein located at upper layer uses a pulley, and the movable block for being located at middle level uses three pulleys side by side, and the hanging object coaster for being located at lower layer uses two pulleys side by side；Both sides are arranged with hangers on the sheath body between movable block, hanging object coaster；Sheath body top is that triangle goes top structure, and lower part is rectangular configuration, and the two sides of rectangular configuration part are enclosed construction described in sheath body, and bottom end is open architecture, and the triangle goes to the entire side in top part to use open architecture；All coasters are all made of bolt, pulley is connected in sheath body by nut by the trepanning on sheath body.The utility model has the beneficial effects that：It is at low cost with work production, operation is dangerous small, value-at-risk is low, the reliable remarkable advantage of powered stable.
Description
Technical field
The utility model belongs to the structure technology that a kind of transmission line of electricity of power industry makes somebody a mere figurehead grounded-line hoisting heavy tool.
Background technology
For being located in the overhead transmission line on plateau by way of high mountain high hill, 47% shaft tower relative relief is larger, 28% bar
Tower relative relief is between 45 ° -87 °, once leading, ground wire leads a burst defect, conventional rope ladder hanger is limited because of angle and structure
System, generally can only 45 ° of relative relief and it is following lead, on-line operation, relative relief more than 45 ° lead, on-line operation it is logical
Led frequently with power failure let-down, the mode of ground wire is repaired, lead to that production cost is high, operation is dangerous big,
The problems such as value-at-risk is high, and power supply reliability is low.To solve this problem as early as possible, it is badly in need of developing a set of safe efficient
Service kit it is stranded to big height difference lead, ground wire is repaired.
Invention content
It is high for current repairing grounded-line production cost, operation is dangerous big, value-at-risk is high, and power supply reliability is low etc. asks
Topic, the utility model proposes 360 ° by development of new to rotate freely five wheel hangers, to solve the big height difference landform of transmission line of electricity
It leads, the important technology problem of ground wire construction and maintenance.For enterprise's cost efficiency, improves power supply reliability and be of great significance.
The technical solution of the utility model is as follows：
Big height difference grounded-line zero damages five skating cars, including sheath body and the suspension centre positioned at upper layer that is separately positioned in sheath body
Coaster, the movable block positioned at middle level, the hanging object coaster positioned at lower layer totally three layers of coaster；The suspension centre coaster for being wherein located at upper layer is adopted
With a pulley, the movable block for being located at middle level uses three pulleys side by side, and the hanging object coaster for being located at lower layer uses two side by side
Pulley；Both sides are arranged with hangers on the sheath body between movable block, hanging object coaster；Sheath body top is that triangle goes to push up
The structure of point, lower part are rectangular configuration, and the two sides of rectangular configuration part described in sheath body are enclosed construction, and bottom end is open type knot
Structure, the triangle go to the entire side in top part to use open architecture；All coasters are all made of bolt, nut passes through in sheath body
On trepanning pulley is connected in sheath body.
Three layers of the utility model suspension centre coaster, movable block, hanging object coaster coaster it is mutual between the upper and lower away from identical.
Suspension centre coaster is the key component that big height difference grounded-line zero damages five skating cars, by using the combination of single-sheaved block,
Change suspension centre, so that five skating cars is fixed in grounded-line, do not damage grounded-line.
Movable block is the innovative point that big height difference grounded-line zero damages five skating cars, can be with by the use of movable block
Suspension centre coaster is set to move back and forth in grounded-line, simple operation promotes working at height efficiency.
The effect of hanging object coaster is completed in working at height, and Work tool and material are lifted by crane.
The selection of suspension centre coaster：
1, three pulleys are fixed in grounded-line, 3 stress, upper lower sheave force balance.
2, three sister blocks stability maintenance on conducting wire is good, and pulley center is located at structure bottom, under gravity, sliding
Phenomenon of turning on one's side will not occur for vehicle.
The selection of movable block：
By the way of pulley combination, a pulley is fixed on shaft tower, ground coordinates personnel by dragging, pull rope controls
Mobile pulley achievees the purpose that control suspension centre pulley.
1, the combination move mode of coaster and rope, by pulley by ground it is vertical drag, pulling force change is reversed
Along the lateral stressed of conducting wire, do not increase the vertical stress of hanging point, be further reduced vertical stress instead, grounded-line will not be made
At damage.
2, suspension centre pulley moves horizontally, the combination move mode of coaster and rope can effectively, accurately control suspension centre cunning
Displacement distance is taken turns, operation is convenient, fast.
The utility model has the beneficial effects that having, work production is at low cost, operation is dangerous small, and value-at-risk is low, power supply
Reliable and stable remarkable advantage.
