Abstract
The utility model belongs to a long-span high-tower assembly foot-distance adjusting wedge of an electric transmission line. An existing root-distance adjusting mode mainly comprises outside wire staying, variable-amplitude wire staying and crossbeam adjusting, wherein outside wire staying is restrained by sites; variable-amplitude wire staying and crossbeam adjusting need a lot of high-altitude hoisting and dismounting work, and safety risks are high. The long-span high-tower assembly foot-distance adjusting wedge of the electric transmission line is characterized in that a horizontal top surface and a supporting surface are formed at the top of the wedge, the horizontal top surface and the supporting surface are connected integrally, the supporting surface is inclined downwards relative to the horizontal top surface, and side planes are formed on two sides of the wedge. The long-span high-tower assembly foot-distance adjusting wedge of the electric transmission line has the advantages that installation convenience and steadiness are achieved, applicability is good, a certain adjusting function is achieved, foot-distance adjusting is conducted on a main pipe conveniently, and a horizontal pipe is placed in place conveniently.
Description
Technical field
The utility model belongs to the vertical auxiliary Work tool of a kind of large leap high tower group, and the large leap high tower of especially a kind of transmission line of electricity group thribble is opened adjusting wedge.
Background technology
Along with the development of power grid construction, particularly cross over increasing of bay, great river, great river, navigation channel etc., cross over greatly high tower (more than height 100m) and in transmission line of electricity, apply and also increase thereupon; The large high tower of crossing over has the features such as highly high, weight is large, difficulty of construction is large.Because of high tower structure feature, supervisor's introversion, opens adjusting therefore need carry out root to supervisor in the vertical process of high tower group, to facilitate horizontal tube in place.Traditional approach mainly comprises that external cable, luffing bracing wire and crossbeam regulate, and wherein external cable is limited by place restriction; Luffing bracing wire and crossbeam adjusting upper air installing and dismounting operation are many, and security risk is large.
Summary of the invention
In order to overcome existing, open the defect that regulative mode high and medium lifting operation is many, place is poor for applicability, the utility model provides the large leap high tower of the transmission line of electricity group thribble that a kind of high-altitude application is few, applicability is good to open adjusting wedge.
For this reason, the utility model is taked following technical scheme: the large leap high tower of a kind of transmission line of electricity group thribble is opened adjusting wedge, connected horizontal top surface and the bearing surface of one formed on the top that it is characterized in that described voussoir, described bearing surface relative level end face is oblique lower setting, and the both sides of described voussoir form side plane.Bearing surface is set, for supporting epimere supervisor on voussoir; Side plane plain cushion is in hypomere supervisor flange bolt hole place; Height and angle that flexible modulation supervisor is set by voussoir, facilitate horizontal tube in place.Voussoir needs between mounting flange bolt space, take that not affect upper and lower flange bolt be tightly just principle.
Described voussoir comprises front end face and rear end face, and the annular hole of evagination is set on described rear end face.Annular hole is connected in steel wire, plays the effect of high-altitude insurance fall arrest.
Salient point is evenly set on described bearing surface, strengthens the frictional force on bearing surface, support firmly, difficult drop-off skids off.
Convex tendon is evenly set on described bearing surface, and the draw-in groove forming between convex tendon is convenient to epimere supervisor's outward flange to fix.
On described bearing surface, form reticulate pattern, strengthen the frictional force on bearing surface, support firmly, difficult drop-off skids off.
The length of described bearing surface is greater than horizontal top surface, and longer bearing surface has good cushioning effect, also has stronger supporting force.According to high tower inclined angle and supervisor's effect of weight, calculate introversion shift value, design angle of inclination, inclined-plane, to regulate introversion value.
The utility model beneficial effect master be easy for installation firm, applicability is good, has certain regulatory function, conveniently supervisor carried out to root open adjusting, to facilitate horizontal tube in place.Overcome traditional root and open the shortcoming that regulative mode high and medium lifting operation is many, place is poor for applicability.
Accompanying drawing explanation
Fig. 1 is wedge structure schematic diagram of the present utility model.
Fig. 2 is the use schematic diagram that high tower group thribble is opened adjusting wedge.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model/invention is further illustrated.
The large leap high tower of a kind of transmission line of electricity group thribble with reference to Fig. 1-Fig. 2 is opened adjusting wedge, and connected horizontal top surface 2 and the bearing surface 3 of one formed on the top of voussoir 1, and bearing surface 3 relative level end faces 2 are oblique lower setting, and the both sides of voussoir 1 form side plane 5.Voussoir 1 comprises front end face 4 and rear end face 7, and the annular hole 6 of evagination is set on rear end face 7.Annular hole 6 is connected in steel wire, locks in flange gusset, plays the effect of high-altitude insurance fall arrest.The reticulate pattern of salient point, convex tendon or formation rule is evenly set on bearing surface 3.Form salient point and reticulate pattern and strengthen the frictional force on bearing surface, support firmly, difficult drop-off skids off.Forming convex tendon is convenient to epimere supervisor's outward flange to fix.The length of bearing surface is greater than horizontal top surface, and longer bearing surface has good cushioning effect, also has stronger supporting force.According to high tower inclined angle and supervisor's effect of weight, calculate introversion shift value, design angle of inclination, inclined-plane, to regulate introversion value.
The utility model arranges oblique bearing surface on voussoir, for supporting epimere supervisor; Side plane plain cushion is in hypomere supervisor flange bolt hole place; Height and angle that flexible modulation supervisor is set by voussoir, facilitate horizontal tube in place.Voussoir needs between mounting flange bolt space, take that not affect upper and lower flange bolt be tightly just principle.
Along with construction extensive, high-grade electricity power engineering, the use of voussoir also will be more and more frequent, particularly cross over increasing of the vertical engineering of the high tower groups such as bay, great river, great river, navigation channel, be voussoir applying in power transmission line vertical tower engineering wide space is provided.
