Abstract

The utility model relates to a cross arm for a concrete pole, which comprises a cross beam with an L-shaped cross section. A through hole is formed at the upper part of the cross beam adjacent to two ends; a supporting frame is fixed on the lateral surface outside the cross beam; mounting holes are formed on two sides of the supporting frame on the cross beam; a supporting plate is connected to the bottom part of the cross beam; another supporting frame is fixed under the supporting frame positioned on the cross beam on the supporting plate; and mounting holes are formed on two sides of the supporting frame on the supporting plate. The utility model has the advantages of convenient manufacture and installation, lower cost and brief and compact appearance, and can not generate distortion, inclination and downslide when being mounted on the concrete pole.

Description

The cement electric pole cross-arm
Technical field
The utility model relates to and is installed in the cross-arm that is used for supporting electric wire on the electric pole, specifically a kind of cross-arm that is installed on the straight line concrete wire pole.
Background technology
Being press-fitted rack ceases to be busy road in China town and country adopts the quantity of straight line concrete wire pole to account for 85%~90%, the cross-arm form of used supporting electric wire is divided into two kinds substantially on concrete wire pole at present, a kind of structure is as crossbeam by angle steel, be fixed with bracing frame on the crossbeam, bottom at crossbeam is connected with triangular supports, is connected with a secondary anchor ear in the lower end of triangular supports; Another kind of be " sticking up formula " cross-arm of split, this " sticking up formula " cross-arm is welded into by steel plate, is the polyhedron that an inside has cavity, will be with the polyhedron anchor ear of prior supporting special use during installation.For the former, the shortcoming that its exists is: install inconveniently, install when not in place, cause easily that cross-arm plane and line direction reverse, unbalance quality problems, at down lead and when installing on the bar electric fixtures additional on electric pole, support forms obstruction sometimes, and weight is heavier.For the latter, the deficiency that it exists is: the cross-arm structure is complicated, and especially the structure of anchor ear is very complicated, and cost of manufacture is higher, and weight is very big.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, the good cement electric pole cross-arm of rear stability is installed.
For achieving the above object, the utility model adopts following scheme: the cement electric pole cross-arm, it has the L-shaped crossbeam of a cross section, crossbeam top has through hole near the place, two ends, on the crossbeam lateral surface, be fixed with bracing frame, be positioned at place, bracing frame both sides on the crossbeam and have installing hole, be connected with a slice gripper shoe in the bottom of crossbeam, be positioned on the gripper shoe bracing frame on the crossbeam under locate to be fixed with a bracing frame, be positioned at place, bracing frame both sides on the gripper shoe and have installing hole.
By such scheme as seen, make bracing frame on the crossbeam and the bracing frame on the gripper shoe and electric pole against, be trapped among the outside of electric pole and make the front end of two shroud rings pass installing hole on the crossbeam and the installing hole on the gripper shoe respectively with two anchor ears, load onto nut at the front end of two anchor ears then, after nut screwed, the cross-arm that the utility model provides can firm being fixed on the electric pole.By combining with two bracing frames this cross-arm is realized fixing on electric pole, improved antitorque, the flexural strength of cross-arm, after cross-arm is locked, can not produce the phenomenon of reversing, tilt, gliding with two anchor ears.
The utility model makes, easy for installation, cost is lower, and profile is succinct, compact, after it was installed on the electric pole, down lead or when installing on the bar electric fixtures additional on electric pole below it can not hindered.
Description of drawings
The front view of Fig. 1 the utility model one embodiment;
The left view of Fig. 2 Fig. 1;
The vertical view of Fig. 3 Fig. 1.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
This cement electric pole cross-arm, it has the L-shaped crossbeam of a cross section 1, be fixed with bracing frame 4 on crossbeam 1 lateral surface, the bottom of crossbeam 1 is connected with a slice gripper shoe 2, be positioned on the gripper shoe 2 bracing frame 4 on the crossbeam 1 under locate to be fixed with a bracing frame 5.Gripper shoe 2 and crossbeam 1 are by being welded to connect.
Referring to Fig. 1
Be positioned at place, bracing frame 4 both sides on the crossbeam 1 and have installing hole 3.Be positioned at place, bracing frame 5 both sides on the gripper shoe 2 and have installing hole 6.Gripper shoe 2 is wide at the top and narrow at the bottom to be trapezoidal, and the outside that is positioned at each installing hole 6 on gripper shoe 2 respectively has 2~4 air-permeating holes 7, and in the present embodiment, the air-permeating hole 7 in the outside of each installing hole 6 is three.Air-permeating hole 7 can reduce the wind carrier model coefficient of cross-arm, reduces wind load, has played the effect of decorating on the other hand.
Referring to Fig. 1, Fig. 3
Crossbeam 1 top has through hole 8 near the place, two ends, and through hole 8 is used to install the insulator of supporting electric wire.Bracing frame 4 is formed by the steel plate bending, and 1 on bracing frame 4 and crossbeam are welding, and the structure of bracing frame 4 is same as the prior art.In addition, the structure of the bracing frame 5 on the gripper shoe 2 and bracing frame 4 are identical.
