Abstract

The utility model discloses an improved single-pole hanger special for a cable bridge frame, comprising a hanging rod and a splint. Taking use direction of the hanger as standard, the upper end of the hanging rod is fixedly connected with a steel girder. The number of the hanging rod is one. And the hanging rod has a first hollow fixing component of which the bottom is formed with a circle of radial baffle plates. Holes are opened on the baffle plates. First bolts are inserted in the holes. The bigger ends of the first bolts block the baffle plates and lock with the first fixing component. The first fixing component is fixed and sleeved at the lower end of the hanging rod. A perforation is opened in the middle part of the splint. The lower ends of the first bolts run through the perforation and run out of the lower end of the splint. Screw caps are screwed with the lower ends of the first bolts. A single-end regulating component is arranged on the hanging rod. The improved single-pole hanger can be conveniently and exactly mounted, can conveniently regulate the height of the hanger, has simple structure and is easily implemented.

Description

The improvement of special single-rod hanger for cable tray

Technical field

The utility model relates to a kind of cable testing bridge special hoisting bar, especially a kind of structure-improved that is applicable to the single-rod hanger of small dimension cable testing bridge.

Background technique

At present, generally all adopt fixedly welding type suspension bracket on the engineering, this suspension bracket is difficult to before construction to accomplish accurate measurement, unified processing.Especially when fixing suspension out-of-flatness, more be difficult to accomplish accurate preprocessing, highly be difficult to regulate, must cut welding at the scene temporarily, bring inconvenience, increase difficulty to construction, incur loss through delay the duration probably, particularly will cut the welding suspension bracket in some inflammable and explosive places very difficult.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of improvement of special single-rod hanger for cable tray, and the improvement of this special single-rod hanger for cable tray not only can make things convenient for accurately installs, and can regulate the height of suspension bracket easily, again and this example simple in structure, easy to implement.

The utility model for the technological scheme that solves its technical problem and adopt is:

A kind of improvement of special single-rod hanger for cable tray, comprise suspension rod and supporting plate, with the suspension bracket service orientation is benchmark, fixedly connected with girder steel in the suspension rod upper end, described suspension rod is one, first fixed block that one hollow is arranged, first fixed block bottom is formed with circle baffle plate radially, offer hole on the baffle plate, first bolt inserts in the hole, the stub end backstop of first bolt is in baffle plate, and with first fixed block spline mutually, the first fixed block fixed cover is located at the suspension rod lower end, the supporting plate middle part offers perforation, the first bolt lower end is passed perforation and is passed the supporting plate lower end, nut screws mutually with the first bolt lower end, suspension rod is provided with single-ended adjusting element, single-ended adjusting element comprises adjustable lever, second nut, second bolt and connecting rod, adjustable lever is a hollow, the rotatable adjustable lever lower end that is positioned, connecting rod upper end, and the adjustable lever upper end fixes and spline with second nut, and the adjustable lever internal diameter is more than or equal to the screwhole diameter of second nut, the second bolt bottom screws mutually with second nut, and the suspension bracket under connecting rod lower end and the adjusting element partly fixes and spline, and the suspension bracket on second bolt upper end and the adjusting element partly fixes and spline.The adjusting element of said structure also can oppositely be installed, promptly adjusting element oppositely after, the upper end and the suspension bracket on the adjusting element of connecting rod partly fixed and spline, the suspension bracket under the second bolt lower end and the adjusting element partly fixes and spline.Towards a direction rotation adjustable lever, second bolt can move to the direction away from adjustable lever, has promptly realized elongation; Rotate adjustable lever to another way, second bolt can contract mobile to the direction near adjustable lever, has promptly realized shortening.

Further technological scheme of the present utility model is:

The rotatable structure that is positioned the adjustable lever lower end in connecting rod upper end is: with the suspension bracket service orientation is benchmark, there is circle back-up ring radially the lower end of adjustable lever to extension of central axis, the back-up ring upper-end surface is provided with ball bearing, the connecting rod upper end is to being extended with circle stop radially away from central axis direction, stop contacts with the ball face of ball bearing.

With the suspension bracket service orientation is benchmark, and described two ends of bearing plate is respectively equipped with spacing preiection upwards.

The adjustable lever upper end fixes with second nut and the structure of spline is: with the suspension bracket service orientation is benchmark, it is second fixed block of cavity that one inside is arranged, and the second fixed block lower end is an opening, second fixed block upper end offers diameter and the identical perforate of the second nut screwhole diameter, second nut and second fixed block upper end internal surface and axial internal surface fix and spline, and the second nut screw is corresponding with perforate, and the second fixed block fixed cover is located at the adjustable lever upper end.

The beneficial effects of the utility model are: because suspension rod is one, first fixed block that one hollow is arranged, first fixed block bottom is formed with circle baffle plate radially, offer hole on the baffle plate, first bolt inserts in the hole, the stub end backstop of first bolt is in baffle plate, and with first fixed block spline mutually, the first fixed block fixed cover is located at the suspension rod lower end, the supporting plate middle part offers perforation, the first bolt lower end is passed perforation and is passed the supporting plate lower end, and nut screws mutually with the first bolt lower end, and suspension rod is provided with single-ended adjusting element, therefore this example not only can make things convenient for installation accurately, and can regulate the height of suspension bracket easily, again and this example simple in structure, easy to implement.
