Abstract

The utility model discloses a cross arm used for a double-circuit straight pole of an overhead line of 10 kilovolts. The cross arm used for the double-circuit straight pole of the overhead line of 10 kilovolts comprises an angle iron cross arm with a bolting hole, the angle iron cross arm is welded with an M-shaped clamper formed through bending, the M-shaped clamper comprises two free arms welded to the angle iron cross arm and a recess portion which is arranged between the two free arms and matches with the outer side wall of the straight pole, and the thickness of the M-shaped clamper is 0.5 to 2 millimeters. According to the structure, a traditional M-shaped sizing block is organically combined with the angle iron cross arm, so that processes of clamping and hole alignment during installation can be omitted, and the installation can be easily performed; the M-shaped clamper is directly formed through bending, so that the machining can be easily performed, and raw materials are saved; the M-shaped clamper is provided with the recess portion matching with the outer side wall of the straight pole, so that the contact area between the M-shaped clamper and the straight pole, and the cross arm used for the double-circuit straight pole of the overhead line of 10 kilovolts is not prone to shifting after installed on the straight pole.

Description

A kind of cross-arm being applied on the straight line pole of 10kV overhead wire double loop

Technical field

The utility model relates to electric force pole tower technical field, particularly a kind of cross-arm being applied on the straight line pole of 10kV overhead wire double loop.

Background technology

Cross-arm is ingredient important in shaft tower, and its effect is for installing insulating and gold utensil, with support wire, lightning conducter, and makes it the safe distance that keeps in accordance with regulations certain.Referring to figs. 1 through Fig. 3, cross-arm on the straight line pole of the existing 10kV of being applied to overhead wire double loop is generally combined by M type parallels 2 ' and angle bar cross-arm 1 ', wherein M type parallels 2 ' comprises a cushion block 21 ', on cushion block 21 ', be welded with a pair of centrosymmetric for clamping the reverse V-shaped folder 22 ' of straight line pole about cushion block, while installing and using, need first a pair of M type parallels 2 ' symmetry to be encircled on the shaft of straight line pole 3 ', then use two angle bar cross-arms 1 ' to be pressed from both sides reality and adjust position, make angle bar crossarm bolt hole aim at M type parallels bolt hole, finally use bolt 4 ' that two angle bar cross-arms 1 ' are fastened on straight line pole 3 '.This structure is independent setting because M type parallels 2 ' and angle bar cross-arm 1 ' separate, and need to clamp and to hole operation, install loaded down with trivial details when installation, inefficiency, and M type parallels 2 ' is welded in by a pair of reverse V-shaped folder 22 ' that cushion block 21 ' is upper to be formed, welding sequence is many, high material consumption.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provide a kind of easy for installation, operating efficiency is high, easy to process, save material be applied to the cross-arm on the straight line pole of 10kV overhead wire double loop.

The utility model solves the technical scheme that its technical problem adopts:

A kind of cross-arm being applied on the straight line pole of 10kV overhead wire double loop, comprise the angle bar cross-arm that is provided with bolt fixing hole, on described angle bar cross-arm, be welded with the M type folder that bending forms, described M type folder comprises two free arms with the welding of angle bar cross-arm, and the suitable concave-arc part of between two free arms and lateral wall straight line pole, the thickness of described M type folder is 0.5 ~ 2mm.

As the improvement of technique scheme, described M type folder is made up of iron material.

The beneficial effects of the utility model are: the utility model by welding M type folder on angle bar cross-arm, traditional M type parallels and angle bar cross-arm are organically combined, when use, only the M type folder symmetry on two angle bar cross-arms need be encircled on the shaft of straight line pole, two angle bar cross-arms are fixed on straight line pole through the bolt fixing hole on two angle bar cross-arms with bolt again, reduce the clamping while installation, to hole operation, easy for installation, and the direct bending and molding of M type folder, abandon by a pair of reverse V-shaped folder and be welded in the M type parallels structure forming on cushion block, process simpler, without using cushion block, raw material are saved, on M type folder, be formed with the concave-arc part suitable with the lateral wall of straight line pole simultaneously, increase the contact area of M type folder and straight line pole, after making cross-arm of the present utility model be installed on straight line pole, be difficult for displacement.

The specific embodiment

With reference to Fig. 4 to Fig. 6, a kind of cross-arm being applied on the straight line pole of 10kV overhead wire double loop of the present utility model, comprises the angle bar cross-arm 1 that is provided with bolt fixing hole 11, is welded with the M type folder 2 that bending forms on described angle bar cross-arm 1, preferably, described M type folder 2 is made up of iron material.For the ease of M type folder 2 bending and moldings, guarantee the intensity of M type folder 2 simultaneously, the thickness of described M type folder 2 is 0.5 ~ 2mm.Described M type folder 2 comprises two free arms 21 that weld with angle bar cross-arm 1, and the suitable concave-arc part 22 of the lateral wall with straight line pole 3 between two free arms 21.When the utility model uses, only M type folder 2 symmetries on two angle bar cross-arms 1 need be encircled on the shaft of straight line pole 3, two angle bar cross-arms 1 are fixed on straight line pole 3 through the bolt fixing hole 11 on two angle bar cross-arms 1 with bolt 4 again, quick and easy for installation.The utility model by welding M type folder 2 on angle bar cross-arm 1, traditional M type parallels and angle bar cross-arm are organically combined, reduce the clamping while installation, to hole operation, easy for installation, and the direct bending and molding of M type folder 2, abandon by a pair of reverse V-shaped folder and be welded in the M type parallels structure forming on cushion block, process simpler, without using cushion block, raw material are saved, on M type folder 2, be formed with the concave-arc part 22 suitable with the lateral wall of straight line pole 3 simultaneously, increase the contact area of M type folder 2 with straight line pole 3, make cross-arm of the present utility model be installed on the rear difficult displacement of straight line pole 3.M type folder 2 by professional welding after, be connected firmly with angle bar cross-arm 1, difficult drop-off.

Certainly, the utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should be within its protection domain.
