Abstract

A low-clearance adjustable suspension wire clamp comprises a connecting base and a busbar wire clamp. Double lugs are arranged on the upper end face of the connecting base, and a strip-shaped hole inthe line direction is formed between the double lugs; the upper end of an internal thread bushing is hinged between the two lugs, the lower end of the internal thread bushing is inserted into the strip-shaped hole, and the internal thread bushing can swing back and forth in the strip-shaped hole around a hinge point; the upper end of an external thread adjusting shaft is in threaded connection with the internal thread sleeve, the lower end of the external thread adjusting shaft is hinged to the busbar wire clamp, and the busbar wire clamp is hung below the connecting base and can horizontallyrotate around the external thread adjusting shaft. The swinging hinge point is moved upwards, the height of the whole structure is reduced, the use requirement of low-clearance tunnel installation ismet, and installation and adjustment are convenient.

Description

technical field

[0001] The invention belongs to the technical field of rail transit rigid suspension systems, and in particular relates to a low headroom adjustable suspension clamp. Background technique

[0002] Rigid suspension system is adopted by more and more lines due to its characteristics of less maintenance, long service life, and no-tension erection of contact wires. Suspension busbar. The currently disclosed "conductive rail holding device" (CN201080055910.X) and "an automatic adjustable elastic suspension clamp along the line" (CN201910993990.6) have the function of swinging a certain angle along the line direction, but their swinging The hinge points are all located at the lower part of the suspension clamps, resulting in a large overall structure height, which cannot be adapted to the installation of low-clearance tunnels. Contents of the invention

[0003] The invention provides a low headroom adjustable suspension clamp, which moves up the swing hinge poi...
