Abstract
The invention discloses a single-end adjusting element of a special hanger for a cable tray, which comprises an adjusting rod, a nut, a bolt and a connecting rod. The adjusting rod is hollow. The using direction of the hanger is used as the reference. The upper end of the connecting rod can be rotatably positioned at the lower end of the adjusting rod, and the upper end of the adjusting rod and the nut are fixed together and in standstill locking. The inner diameter of the adjusting rod is greater than or equal to the diameter of the thread hole of the nut. The lower part of the bolt is screwed with the nut. The lower end of the connecting rod and the hanger part under the adjusting rod are fixed together and in standstill locking; and the upper end of the bolt and the hanger part above the adjusting rod are fixed together and in standstill blocking. The hanger height can be conveniently and accurately adjusted, and the invention has the advantages of simple structure and easy implementation.
Description
Technical field
The present invention relates to a kind of controlling device, especially a kind of height-adjusting device of cable testing bridge special hoisting bar.
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, height can't accurately be controlled, must cut welding at the scene temporarily, bring inconvenience to construction, increased difficulty, incured 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 invention provides a kind of single-end adjusting element of special hanger for cable tray, the suspension bracket that this adjusting element is installed can make things convenient for the height of regulating suspension bracket accurately, and this example is simple in structure, and is easy to implement.
The present invention for the technological scheme that solves its technical problem and adopt is:
A kind of single-end adjusting element of special hanger for cable tray, comprise adjustable lever, nut, bolt and connecting rod, adjustable lever is a hollow, with the suspension bracket service orientation is benchmark, the rotatable adjustable lever lower end that is positioned, connecting rod upper end, the adjustable lever upper end fixes and spline with nut, and the adjustable lever internal diameter is more than or equal to the screwhole diameter of nut, the bolt bottom screws mutually with nut, suspension bracket under connecting rod lower end and the adjusting element partly fixes and spline, and the suspension bracket on 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 bolt lower end and the adjusting element partly fixes and spline.Towards a direction rotation adjustable lever, bolt can move to the direction away from adjustable lever, has promptly realized elongation; Rotate adjustable lever to another way, bolt can contract mobile to the direction near adjustable lever, has promptly realized shortening.
Further technological scheme of the present invention 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.
The adjustable lever upper end fixes with nut and the structure of spline is: with the suspension bracket service orientation is benchmark, it is the fixed block of cavity that one inside is arranged, and the fixed block lower end is an opening, the fixed block upper end offers the diameter hole identical with the nut screwhole diameter, nut and fixed block upper end internal surface and axial internal surface fix and spline, and the nut screw is corresponding with hole, and the fixed block fixed cover is located at the adjustable lever upper end.
The invention has the beneficial effects as follows: because adjustable lever is a hollow, with the suspension bracket service orientation is benchmark, the rotatable adjustable lever lower end that is positioned, connecting rod upper end, the adjustable lever upper end fixes and spline with nut, and the adjustable lever internal diameter is more than or equal to the screwhole diameter of nut, the bolt bottom screws mutually with nut, suspension bracket under connecting rod lower end and the adjusting element partly fixes and spline, suspension bracket on bolt upper end and the adjusting element partly fixes and spline, therefore this routine suspension bracket is installed can make things convenient for the height of regulating suspension bracket accurately, and this example is simple in structure, and is easy to implement.
