Abstract
The line maintenance horizontal suspension ladder of the utility model belongs to the power transmission and transformation field and comprises a horizontal rod (1), vertical rods (2) and hooks (3). The horizontal rod (1) is provided with a casing pipe (7) thereon. The part where the casing pipe (7) and the horizontal rod (1) are connected is provided with a fastening structure. On the hooks (3) and the intermediate section of the horizontal rod (1) are arranged links (4), which are provided with a triangular pull rope (5). The horizontal suspension ladder can be suspended at two ends of a line insulator. An operator can stand on the suspension ladder with hands holding the insulator to perform the operation without damage to the insulator. In addition, the horizontal suspension ladder is simple in structure, convenient in use, safe and reliable.
Description
Technical field:
The utility model belongs to the horizontal hanging ladder of line upkeep instrument, especially line maintenance in power transmission and transformation field.
Background technology:
In the installation and maintenance process of power transmission and transformation line, often need the staff to install, change aloft and mend screw and pin on the wiring road, normally personnel stand in the enterprising line operate of insulator, both dangerous, also damage the long insulator of ring-shaped rubber sheet, the particularly time limit on the insulator easily, because rubber is aging, be easy to damage, bring unnecessary loss for power transmission and transformation department.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of simple in structure, esy to use, safe and reliable, operating personnel can be by the horizontal hanging ladder of line maintenance of operation.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise cross bar, vertical rod and hook, vertical rod is positioned at the two ends of cross bar, and hook is positioned at the termination of vertical rod.
As improved technical scheme, the stage casing with cross bar on hook is provided with link, is provided with leg-of-mutton stay cord on link, makes hanging ladder safer.
As further improvement, on cross bar, be provided with sleeve pipe, the junction of sleeve pipe and cross bar is provided with retention mechanism, described retention mechanism can be a locking head, also can be on cross bar at interval be provided with pin hole, an end that is connected with cross bar at sleeve pipe also is provided with pin hole, is provided with pin in pin hole, can regulate the length of hanging body.
As further improvement, the hook in the vertical rod of a side is flat hook, and symmetry is provided with pin hole on flat hook.
As further improvement project again, the termination of stay cord is provided with the wire rope snap close.
The horizontal hanging ladder of the utility model design can be suspended on the two ends of line insulator, and operating personnel may stand on the hanging ladder hand steered insulator and operate, and do not damage insulator, and simple in structure, esy to use, safe and reliable.
