Abstract

The utility model relates to a cable bridge support arm which comprises a support beam with cross section in flat-bottomed U shape; one end of the support beam is fixedly provided with a mounting seat; the support beam is distributed with strip-shaped convex reinforcing ribs formed by pressing; and the strip-shaped convex reinforcing ribs pass through three walls of the support beam. As the support beam is provided with the strip-shaped convex reinforcing ribs by pressing which pass through three walls of the support beam, the strip-shaped convex reinforcing ribs can still ensure the support beam to have enough strength and rigidity under the condition of reducing the thickness of a steel plate used for making the support beam. Along with the reduction of the thickness of the steel plate, the production cost is also correspondingly reduced, and the economic benefit is further improved.

Description

The cable testing bridge trailing arm

Technical field

The utility model relates to a kind of cable testing bridge trailing arm, particularly a kind of in light weight, cable testing bridge trailing arm that intensity is high.

Background technique

The cable testing bridge trailing arm is the support that is used for installing cable testing bridge.At present, the cable testing bridge trailing arm structures of a fitting seat of end welding that are the joist of flat U-shaped at cross section that adopt more.The joist of flat U-shaped generally all is to be made by the direct bending of a steel plate, because its each face all is planes, does not have reinforced structure, and therefore under the situation that satisfies its rigidity and requirement of strength, the steel plate of making joist can be thicker.Along with rising steadily of the cost of raw material, adopt existing structure to produce trailing arm again and obviously do not had Economy.

The model utility content

The purpose of this utility model provides a kind of cable testing bridge trailing arm, does not have a problem of Economy in order to solve to produce the existing structure trailing arm.

For achieving the above object, the utility model adopts following technological scheme: a kind of cable testing bridge trailing arm, comprise that cross section is the joist of flat U-shaped, one end of joist is installed with fitting seat, be laid with the strip projected parts stiffening rib of compacting on the described joist, described each strip projected parts stiffening rib all passes through three walls of joist.

Described each strip projected parts stiffening rib is parallel to each other.

Described each strip projected parts stiffening rib evenly is provided with along the joist length direction.

The trend of described each strip projected parts stiffening rib is vertical mutually with the length direction of described joist.

Cable testing bridge trailing arm of the present utility model, on its joist, be suppressed with strip projected parts stiffening rib, described strip projected parts stiffening rib be set under the situation that reduces the steel plate thickness of making joist, guaranteed that still joist has enough strength and stiffness through its three walls.Along with the reduction of steel plate thickness, cost of production is also descended accordingly, and then has improved economic benefit.

Embodiment

Shown in Fig. 1,2,3, cable testing bridge trailing arm of the present utility model comprises that a cross section is the joist 1 of flat U-shaped, and an end of joist 1 is welded with a fitting seat 3, and fitting seat 3 is provided with mounting hole.Its length direction of described joist 1 upper edge evenly is suppressed with strip projected parts stiffening rib 2, and each strip projected parts stiffening rib 2 all passes through three walls of joist 1, has so just formed the strip projected parts stiffening rib 2 of C shape.Each strip projected parts stiffening rib 2 is parallel to each other, and its trend is vertical mutually with the length direction of joist 1.

Claims

1. a cable testing bridge trailing arm comprises that cross section is the joist of flat U-shaped, and an end of joist is installed with fitting seat, it is characterized in that: be laid with the strip projected parts stiffening rib of compacting on the described joist, described each strip projected parts stiffening rib all passes through three walls of joist.

2. cable testing bridge trailing arm according to claim 1 is characterized in that: described each strip projected parts stiffening rib is parallel to each other.

3. cable testing bridge trailing arm according to claim 1 and 2 is characterized in that: described each strip projected parts stiffening rib evenly is provided with along the joist length direction.

4. cable testing bridge trailing arm according to claim 3 is characterized in that: the trend of described each strip projected parts stiffening rib is vertical mutually with the length direction of described joist.
