Abstract

The utility model discloses a fixing clamp for welding an electric copper-clad steel grounding wire, which comprises a support and at least 2 fixing clamp groups fixedly connected on the support, wherein the number of the fixing clamp groups is the same as that of the grounding wires connected with a welding point, each fixing clamp group corresponds to one grounding wire, each fixing clamp group comprises at least 2 fixing clamps, and all the fixing clamps in one fixing clamp group are separately arranged along the corresponding grounding wire laying direction. The utility model adopts the fixing clamp group to clamp the ground wire to be connected, so that the deformation stress of the ground wire to be connected acts on the fixing clamp, and further the welding mould works in a free state, the damage degree is greatly reduced, 40-50 welding points can be welded on one mould, and the utilization rate is improved by nearly 1 time. Meanwhile, as the welding mould works in a free state, the quality of a welding point is also ensured, and the formation after welding is very attractive.

Description

Fixing clamp for welding electric copper-clad steel grounding wire

Technical Field

The utility model relates to a fixing clamp, in particular to a fixing clamp for welding an electric copper-clad steel grounding wire.

Background

The situation that copper-clad steel is used as a main grounding material in electrical grounding construction is popularized, and the copper-clad steel materials are disc-shaped when being delivered, are very similar to cable reels, and need to be straightened before construction so as to meet the requirements of site construction. The stress of the straightened copper-clad steel cannot be completely eliminated, the existing connection mode of the grounding node adopts hot-melt welding, a professional welding mold is used, the use effect of the mold is optimal in a free state, and otherwise the mold is extremely easy to damage. However, the on-site condition is difficult to meet the optimal condition, because the straightened copper-clad steel grounding wire has stress, the stress of the copper-clad steel grounding wire is mainly concentrated at a mould by adopting the existing welding mode, the mould is stressed greatly and is easy to damage, and generally 20-25 welding points welded by one mould are damaged and can not be used. Therefore, a fixing clamp for welding the electrical copper-clad steel grounding wire is required to be designed to share the deformation stress of the copper-clad steel grounding wire, so that the service life of a welding mold is prolonged, and the working efficiency is improved.

SUMMERY OF THE UTILITY MODEL

The utility model provides a fixing clamp for welding an electric copper-clad steel grounding wire, which is used for sharing the deformation stress of the copper-clad steel grounding wire so as to prolong the service life of a welding mould and improve the working efficiency.

The technical scheme adopted by the utility model for solving the technical problems in the prior art is as follows: the utility model provides an electric copper covers steel earth connection mounting fixture for welding, includes that support and rigid coupling are in 2 at least fixation clamp groups on the support, the number of fixation clamp group is the same with the earth connection radical that the welding point is connected, every the fixation clamp group corresponds an earth connection, every the fixation clamp group contains 2 at least fixation clamps, one all in the fixation clamp group the fixation clamp is laid the direction separately along rather than the earth connection that corresponds and is arranged.

The bracket is formed by welding angle steels.

The utility model has the advantages and positive effects that: the grounding wire to be connected is clamped at the welding point by adopting the fixing clamp group, so that the deformation stress of the grounding wire to be connected acts on the fixing clamp, the welding mould works in a free state, the damage degree is greatly reduced, 40-50 welding points can be welded in one mould, and the utilization rate is improved by nearly 1 time. Meanwhile, as the welding mould works in a free state, the quality of a welding point is also ensured, and the formation after welding is very attractive. The fixing clamp is simple in structure and convenient to manufacture, the bracket can be made of sporadic materials, the type selection of the fixing clamp is easy, and the fixing clamp is common in the market. After the copper-clad steel grounding wire is in place, the clamp is pressed down, and the use is convenient. Auxiliary personnel can keep away from the ignition point, reduces the safety risk. In conclusion, the welding device can effectively ensure the welding quality, reduce the safety risk and improve the construction efficiency by about 45 percent.

Drawings

FIG. 1 is a schematic structural view of example 1 of the present invention;

fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.

In the figure: 1. a support; 2. a ground line; 3. a fixing clip; 4. and (7) welding points.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:

referring to fig. 1 and 2, a fixing clamp for welding an electrical copper-clad steel ground wire includes a bracket 1 and at least 2 fixing clamp groups fixedly connected to the bracket, the number of the fixing clamp groups is the same as that of the ground wires 2 connected to welding points 4, each fixing clamp group corresponds to one ground wire 2, each fixing clamp group includes at least 2 fixing clamps 3, and all the fixing clamps 3 in one fixing clamp group are separately arranged along the laying direction of the corresponding ground wires 2.

In the embodiment, the bracket 1 is formed by welding angle steel; each of the fixing clip sets includes 2 fixing clips 3.

Example 1:

referring to fig. 1, the fixing clamp adopting the above scheme is provided with 3 fixing clamp groups, wherein 2 fixing clamp groups are arranged on a straight line and used for fixing two grounding wires 2 which are horizontally and oppositely connected, the other 1 fixing clamp group is arranged in a vertical direction and used for fixing a grounding wire which is vertically connected, and the 3 fixing clamp groups are arranged in a T shape.

Example 2:

unlike embodiment 1, the fixing clip group has two for fixing two ground wires 2 connected horizontally oppositely.

By analogy, when four grounding wires 2 need to be fixed, 4 fixing clamp groups are arranged on the bracket. When a plurality of grounding wires 2 need to be fixed, the same number of fixing clamp groups are arranged on the bracket.

The use method of the utility model comprises the following steps:

1) the fixing clamps are arranged at the welding points, the positions are adjusted, 1 fixing clamp group corresponds to one grounding wire 2, and then the corresponding grounding wire 2 is clamped by the fixing clamps.

2) Adjusting the gap between the ground wires.

3) And (4) mounting a welding mould, wherein the welding mould is in a free state because the deformation stress of the grounding wire 2 acts on the fixing clamp.

4) And (6) welding.

5) And after the welding is finished, the welding die and the fixing clamp are withdrawn.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
