The tool cannot stretch into the inner side of the single-convex hoop, the end head of the bolt on the side is fastened infirm, the nut on the other end is fastened tightly by the tool in a rotating mode, the bolt rotates simultaneously, the torque does not meet the requirement, the fastening force is insufficient, and the parts are not fixed together by enough clamping force, so that transverse sliding or loose separation of a connecting piece between two parts is caused, unnecessary shearing force or large axial stress can be applied to the bolt, and finally the bolt can be broken.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cross arm fixing device in 10kV circuit tangent bar to among the solution prior art, when the installation of the perpendicular iron of tangent bar, together rotate with the nut during the bolt-up, lead to installing insecure problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a cross arm fixing device in 10kV circuit tangent bar, includes fixed clamp and single protruding staple bolt, fixed clamp card is in on the single protruding staple bolt, fixed clamp is used for blocking the head of bolt.

Furthermore, the central position of single protruding staple bolt is provided with the convex part, the bolt mounting hole has been seted up on the convex part.

Further, the fixed clamp is clamped at the convex part of the single convex hoop.

Further, the fixing clip includes a catching portion for catching on the convex portion and a concave portion for catching a head portion of the bolt.

Further, the concave part is groove-shaped, and the head edge of the bolt is clamped on the inner wall of the concave part.

Furthermore, the clamping part comprises two grooves with opposite notches, and the top edges of the groove walls of the grooves are fixedly connected with the top edges of the groove walls of the concave parts.

Further, fixed clamp is the fixed clamp of steel.

Furthermore, the fixed clamp is formed by bending a steel plate.

The utility model has the advantages as follows:

(A) the utility model provides a fixing device makes the bolt head rely on fixed clamp to tightly detain the jail on single protruding staple bolt, prevents that the bolt from rotating to fastening nut is firm with steel clamp device and founding iron cross arm installation, reaches higher moment requirement very easily.

(B) The utility model discloses the pole is hugged closely to well fixed clamp rear side, prevents that the bolt from droing, has reached the bolt and has violently just straightened the effect, has guaranteed that compaction device can last effective work.

(C) The utility model discloses a firm is detained to fixed clamp, and the skew, slope phenomenon obtain very big improvement, and construction quality and effect obviously improve.

(D) The utility model discloses the scheme is reasonable, simple structure, realizes easily, can full play vacuum compaction's advantage.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

The following detailed description is exemplary in nature and is intended to provide further details of the invention. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention.

As shown in fig. 1 and 2, the embodiment of the utility model provides a well cross arm fixing device in 10kV circuit tangent bar, including fixed clamp 1 and the single protruding staple bolt 2 that the steel sheet was buckled and is formed, fixed clamp 1 card is on single protruding staple bolt 2, and fixed clamp 1 is used for blocking the head of bolt 3. In this embodiment, the central point of the single convex hoop 2 is provided with a convex portion 21, the convex portion 21 is provided with a bolt mounting hole, and the fixing clamp 1 is clamped at the convex portion 21 of the single convex hoop 2.

In one embodiment of the present invention, the fixing clip 1 includes a catching portion 11 for catching on the protruding portion 21 and a recessed portion 12 for catching the head of the bolt 3. The recess 12 is groove-shaped, and the head edge of the bolt 3 is clamped on the inner wall of the recess 12. The clamping part 11 comprises two grooves with opposite notches, and the top edges of the groove walls of the grooves are fixedly connected with the top edges of the groove walls of the concave part 12.

The utility model discloses phase cross arm fixing device application method in 10kV circuit tangent bar is as follows:

firstly, the bolt 3 penetrates through a bolt mounting hole in the single convex hoop 2, and then the fixed hoop 1 is clamped at the convex part 21 of the single convex hoop 2, so that the position of the fixed hoop 1 is fixed.

Then install single protruding staple bolt 2 on the pole, go on installing the mounting hole alignment bolt 3 on the iron cross arm of standing, it can to screw up the nut afterwards.

At the in-process of screwing up the nut, because fixed clamp 1 card is on single protruding staple bolt 2, and the head of bolt 3 card is on fixed clamp 1 again, so can not take place to slide when screwing up the nut, prevent that the bolt from rotating, droing, the installation is more fastening.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
