Abstract

The utility model discloses a novel U-shaped stay wire hoop which comprises a U-shaped hoop plate, wherein two bolt holes are symmetrically formed at the two ends of the U-shaped hoop plate; the two ends of the U-shaped hoop plate are connected by a bolt; a bolt bar of the bolt is connected with a stay wire hardware fitting in a series sleeving manner; a gasket is arranged between a nut and the hoop plate where the bolt hole is formed; and the bolt holes are formed in tangent lines of a bent semicircle of the hoop. A tensile force of a stay wire is transmitted to the hoop plate by the bolt bar to ensure that the hoop plate is subjected to a longitudinal tension stress, so that stress concentration of the semicircle hoop, formed due to the fact that the plate is bent is avoided, and the bearing capacity of the hoop can be improved effectively. The novel U-shaped stay wire hoop avoids the stress concentration formed due to the fact that the plate is bent, saves a material, simplifies working processes, and is simple in structure, and the bearing capacity of the hoop is improved effectively.

Description

A kind of novel U-shaped backguy anchor ear
Technical field
The utility model relates to the electric armour clamp that transmits mechanical load, relates in particular to a kind of novel U-shaped backguy anchor ear.
Background technology
At present, in, the shaft tower in the low pressure overhead distribution uses the reinforced concrete pole of annular section in a large number, pole guy often need be set with equalizing contactor tension force on angle pole and terminal pole, namely connect with anchor ear between backguy and the electric pole.The anchor ear that is used for the connection pole guy also often is called the backguy anchor ear, be generally two blocks of semicircle anchor ear plates, being connected anchor ear with other compares, the load that the backguy anchor ear bears is bigger, especially crooked starting the arc place at semicircle anchor ear exists bigger stress to concentrate (result of finite element shows that the factor of stress concentration at this place is 2.92), the backguy anchor ear is everlasting and is ruptured herein in line construction and use, even the accident that causes down bar and disconnected bar happens occasionally, for this reason, industry is normal to be adopted at the crooked arcing point of semicircle anchor ear plate place, the method of bolt hole both sides stiffener solves this type of problem, the cross section that perhaps increases the anchor ear plate increases its supporting capacity, but these two kinds of methods have all increased material usage, and the stiffener method also makes the anchor ear production technology become loaded down with trivial details (having increased the stiffener welding sequence), and the two has all strengthened the cost of production of anchor ear.
The utility model content
In order to solve the deficiency that prior art exists, the utility model specifically discloses a kind of novel U-shaped backguy anchor ear, this backguy anchor ear improves the anchor ear supporting capacity by the method that reduces the factor of stress concentration, not only need not increase material usage, and save stiffener operation and bent plate operation.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of novel U-shaped backguy anchor ear comprises U-shaped anchor ear plate, and U-shaped anchor ear plate two ends symmetric position is provided with two bolts hole, and U-shaped anchor ear plate two ends connect by bolt, and the screw rod of bolt is connected with backguy gold utensil string cover;
Described bolt passing through bolt hole is connected with nut, and screw bolt and nut matches with bolt hole and electric pole, establishes a pad between the U-shaped anchor ear plate at nut and bolt hole place;
The bend radius of described U-shaped anchor ear plate is the radius of place electric pole;
Described U-shaped anchor ear plate is steel band;
The polished rod length of described screw rod is less than the diameter of place, anchor ear place electric pole;
The length computation formula of described U-shaped anchor ear plate is: L=π * R+R*2+L 0* 2
Wherein L is the length of U-shaped anchor ear plate, and R is the radius of electric pole, L 0For the bolt hole inside edge apart from anchor ear plate end face length.
When making, according to the pole diameter that the anchor ear place is installed, calculate required steel band length, after the blanking at steel band two ends symmetric position auger shell keyhole; Be that bend radius becomes U-shaped with the steel band symmetric curvature with 1/2nd of pole diameter; According to bore diameter and pole diameter processing bolt, nut and pad; U-shaped anchor ear plate is placed on the electric pole, then bolt head is passed two holes on the U-shaped anchor ear plate, simultaneously backguy gold utensil string is enclosed within on the screw rod, the polished rod length of screw rod is less than the diameter of place, anchor ear place electric pole, so just can guarantee to screw nut, hold electric pole tightly and screw nut and can make U-shaped anchor ear plate hold electric pole tightly.
The beneficial effects of the utility model are: spiro keyhole position is on the tangent line of the crooked semicircle of U-shaped anchor ear plate, the pulling force of backguy is delivered to U-shaped anchor ear plate by screw rod, make U-shaped anchor ear plate be subjected to longitudinal tension stress, avoid the semicircle anchor ear to concentrate because of the stress that bent plate forms, made the supporting capacity of anchor ear effectively improve; The stress that this novel U-shaped backguy anchor ear has not only been avoided causing because of bent plate is concentrated, and has effectively improved the supporting capacity of anchor ear, and saves material, simplifies working process, and is simple in structure.
Description of drawings
Fig. 1 backguy anchor ear work schematic diagram;
U-shaped anchor ear plate behind Fig. 2 bending forming;
Among the figure, 1U shape anchor ear plate, 2 bolt heads, 3 screw rods, 4 nuts, 5 pads, 6 backguy gold utensils, 7 bolts hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated: as shown in Figure 1, comprise curved U-shaped anchor ear plate 1, U-shaped anchor ear plate 1 two ends symmetric position is provided with two bolts hole 7, U-shaped anchor ear plate 1 two ends connect by bolt, bolt comprises bolt head 2 and screw rod 3, and the screw rod 3 of bolt is connected with backguy gold utensil 6 string covers; Bolt passing through bolt hole 7 is connected with nut 4, and screw bolt and nut 4 matches with bolt hole 7 and electric pole, establishes a pad 5 at 1 of the U-shaped anchor ear plate at nut 4 and bolt hole 7 places; The bend radius of U-shaped anchor ear plate 1 is the radius of place electric pole; U-shaped anchor ear plate 1 is steel band.
The length computation formula of U-shaped anchor ear plate 1 is: L=π * R+R*2+L 0* 2
Wherein L is the length of U-shaped anchor ear plate 1, and R is the radius of electric pole, L 0For bolt hole 7 inside edges apart from U-shaped anchor ear plate 1 end face length.
When making, according to the pole diameter that the anchor ear place is installed, calculate required steel band length, after the blanking at steel band two ends symmetric position auger shell keyhole 7; As shown in Figure 2, be that bend radius becomes U-shaped with the steel band symmetric curvature with 1/2nd of pole diameter; According to bore diameter and pole diameter processing bolt, nut 4 and pad; The U-shaped anchor ear is placed on the electric pole, then bolt is passed two holes on the anchor ear plate 1, simultaneously backguy gold utensil 6 strings are enclosed within on the screw rod, screw nut 4 and can make anchor ear hold electric pole tightly.
Bolt hole 7 is positioned on the tangent line of the crooked semicircle of U-shaped anchor ear plate, the pulling force of backguy is delivered to U-shaped anchor ear plate 1 by screw rod 3, make U-shaped anchor ear plate 1 be subjected to longitudinal tension stress, avoided the semicircle anchor ear to concentrate because of the stress that bent plate forms, make the supporting capacity of anchor ear effectively improve.
The stress that this novel U-shaped backguy anchor ear has not only been avoided causing because of bent plate is concentrated, and has effectively improved the supporting capacity of anchor ear, and saves material, simplifies working process, and is simple in structure.
