Description

High-strength cable bridge

Technical Field

The utility model relates to a cable testing bridge technical field especially relates to a high strength cable testing bridge.

Background

The cable bridge is widely applied to laying cables such as power cables, control cables, lighting lines, telecommunication cables and the like in cable construction engineering, and is generally divided into a groove type, a tray type, a ladder type, a grid type and other structures. The existing cable bridge has the advantages of simple structure, flexible configuration and the like, but the shock resistance and the bearing capacity are poor, and the cable bridge is easy to deform when being impacted in the actual use process, so that the cable bridge is easy to collapse or damage when the borne cables are too much, the cable bridge needs to be replaced, and a large amount of manpower and maintenance cost need to be invested.

Disclosure of Invention

In view of this, the utility model aims at providing a high strength cable testing bridge can overcome prior art's not enough.

The utility model aims at realizing through the following technical scheme:

the utility model provides a high strength cable testing bridge, includes the crane span structure body, the crane span structure body comprises bottom plate and both sides board, is equipped with the draw-in groove isometric with the bottom plate in bottom plate bottom surface bilateral symmetry, has connect polylith spring steel board in the draw-in groove to in the big more place of atress, the spring steel board of arranging is more, otherwise then arranges less.

The middle part of the bottom surface of the bottom plate is provided with a long mounting groove, the middle part of the spring steel plate is provided with a mounting hole corresponding to the spring steel plate, the two sides of the spring steel plate are clamped in the clamping grooves, and the middle part of the spring steel plate is fixedly connected with the long mounting groove through bolts.

The rubber strip is embedded in the clamping groove.

The bottom plate, the clamping groove and the long mounting groove are of an integrated extrusion forming structure.

Compared with the prior art, the utility model discloses a high-strength cable bridge, which comprises a bridge body, wherein the bridge body consists of a bottom plate and two side plates, clamping grooves with the same length as the bottom plate are symmetrically arranged on two sides of the bottom surface of the bottom plate, and a plurality of spring steel plates are clamped in the clamping grooves; during installation, the spring steel plates are reasonably arranged according to the stress condition of the cable bridge, namely, the more the spring steel plates are arranged at the place with larger stress, otherwise, the less the spring steel plates are arranged, the production and installation costs can be effectively reduced under the condition that the cable bridge is ensured to have good strength and rigidity, and the weight of the cable bridge is reduced.

The utility model has the advantages that:

the utility model discloses simple structure, manufacturing cost and use cost are lower, through arranging the spring steel board in a flexible way on the cable testing bridge, not only guarantee that it has good intensity, rigidity, shock resistance and bearing capacity, improve its life greatly, can reduce the weight of cable testing bridge moreover, and the practicality is strong.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.

Drawings

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, in which:

fig. 1 is a schematic front structural view of the present invention.

FIG. 2 is a schematic view of the bottom structure of the present invention

Fig. 3 is a schematic perspective view of the present invention.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 1-3, a high-strength cable bridge comprises a bridge body, the bridge body is composed of a bottom plate 1 and two side plates 2, various types of cables or buses can be laid on the bottom plate 1, clamping grooves 3 with the same length as the bottom plate 1 are symmetrically arranged on two sides of the bottom surface of the bottom plate 1, a plurality of spring steel plates 4 are clamped in the clamping grooves 3, the more the spring steel plates 4 are arranged at the places with larger stress, and the less the spring steel plates are arranged on the contrary. Through nimble increase and decrease spring steel plate 4, not only can guarantee the intensity of cable testing bridge, can reduce the weight of cable testing bridge in addition to very big degree, avoid the material extravagant.

Be equipped with microscler mounting groove 5 in the middle part of 1 bottom surface of bottom plate, be equipped with the mounting hole corresponding with it in the middle part of

spring steel sheet

4, 4 both sides joints of spring steel sheet are in draw-in groove 3, and the middle part links firmly with microscler mounting groove 5 through bolt 6, guarantees that spring steel sheet 4 receives external force to make difficult along draw-in groove 3 removal, and it is better to connect the steadiness.

Rubber strip 7 has been inlayed at draw-in groove 3, the dismouting of the spring steel sheet 4 of not only being convenient for more, and spring steel sheet 4 receives rubber strip 7 to inject moreover, and difficult removal connects the steadiness good.

The bottom plate 1, the clamping groove 3 and the long mounting groove 5 are of an integrated extrusion forming structure, so that the processing technology is simplified, and the processing cost is reduced.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
