Abstract
The utility model relates to a cable bridge bracket, including a bearer bar which cross section is in a flat bottom U shape, one end of the bearer bar is fixed on a mounting seat, and the bottom face of the bearer bar is provided with pressed convex reinforcing rods. According to the utility model, by means of the pressed convex reinforcing rods arranged on the bottom face of the bearer bar, it is possible to reduce the steel plate thickness for producing the bearer bar and ensure enough strength and stiffness of the bearer bar still. The thickness of the steel plate is reduced, such that the production cost may be reduced and economic benefit is improved.
Description
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, an end of joist is installed with fitting seat, is laid with the protruding reinforcing rib of compacting on the bottom surface of described flat U-shaped structure joist.
Two bending parts of described flat U-shaped structure joist are suppressed with inwardly protruded triangle stiffening rib at interval.
The protruding reinforcing rib of described compacting is waist shape structure, and the length direction of the protruding reinforcing rib of this waist shape is vertical mutually with the length direction of joist.
The protruding reinforcing rib of described waist shape is evenly laid on the bottom surface of flat U-shaped structure joist along its length.
The protruding reinforcing rib of described waist shape and triangle stiffening rib are provided with at interval.
The top margin top corresponding with the protruding reinforcing rib of each waist shape that described each triangle stiffening rib is positioned on the bottom surface of flat U-shaped structure joist is in on the bar straight line or near being on same the straight line.
Cable testing bridge trailing arm of the present utility model, be laid with the protruding reinforcing rib of compacting in the bottom surface of its flat U-shaped structure joist, described protruding reinforcing rib be set under the situation that reduces the steel plate thickness of making joist, guaranteed that still joist has enough strength and stiffness.Along with the reduction of steel plate thickness, cost of production is also descended accordingly, and then has improved economic benefit.
Two bending parts of flat U-shaped structure joist are suppressed with inwardly protruded triangle stiffening rib, owing to be the triangle stiffening rib of compacting, therefore can not increase the weight of this trailing arm, and the triangle stiffening rib of this compacting plays the same effect with welding stiffening rib around the corner, promptly rigidity and the intensity that improves joist is played a positive role.
The protruding reinforcing rib of waist shape and triangle stiffening rib are provided with at interval, the top margin top corresponding with the protruding reinforcing rib of each waist shape that each triangle stiffening rib is positioned on the bottom surface of flat U-shaped structure joist is in on the bar straight line or near being positioned at on the bar straight line, optimized this joist bending resistance and antitorque mechanical property like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Shown in Fig. 1,2, 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 4, and fitting seat 4 is provided with mounting hole 5.The length direction that evenly is laid with length direction and joist on the bottom surface of joist 1 is orthogonal, the waist shape protruding reinforcing rib 3 of compacting.Simultaneously, be suppressed with inwardly protruded triangle stiffening rib 2 at two bending parts of flat U-shaped structure joist, described triangle stiffening rib 2 is evenly laid along the seamed edge of joist, and the protruding reinforcing rib 3 of waist shape is provided with at interval with triangle stiffening rib 2.Simultaneously, the triangle stiffening rib 2 protruding reinforcing rib 3 corresponding tops that are positioned at top margin and waist shape on the bottom surface of flat U-shaped structure joist are in on the bar straight line.
Claims (6)
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: the protruding reinforcing rib that is laid with compacting on the bottom surface of described flat U-shaped structure joist.
2. cable testing bridge trailing arm according to claim 1 is characterized in that: two bending parts of described flat U-shaped structure joist are suppressed with inwardly protruded triangle stiffening rib at interval.
