Adjustable combined corner pulley device and adjustment method

Abstract

The invention provides an adjustable combined corner pulley device and an adjustment method. The laying device includes: a positioning mounting seat; a corner pulley, the corner pulley is rotatably installed on both side plates of a pulley support through a rotating shaft , and the rotating shaft and the side plate are detachably connected; the length-adjustable length adjusting member is detachably connected between the mounting seat and the pulley support. The invention can prevent the cable laying position at the corner from overlapping to the inside of the corner, ensure the cable laying standard and orderly, reduce the occurrence of safety accidents caused by uneven stress on the bridge, reduce the operation difficulty of workers, and improve the cable laying efficiency; it is convenient to separate the cable from the pulley support , which solves the defect that it is difficult to remove the pulley block after the cable is laid in the prior art.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an adjustable combined corner pulley device and an adjustment method. Background technique [0002] At this stage, when laying large-section cables at corners, the operation is more difficult. When using conventional corner pulleys, the laying position is difficult to control, which makes the bridge stress uneven and dangerous for personnel to operate. Moreover, the cables are easy to accumulate inside the corner. After the cable is laid, it is difficult to remove the corner pulley block, which greatly increases the difficulty of construction. SUMMARY OF THE INVENTION [0003] In view of the above situation, the present invention provides an adjustable combined corner pulley device and an adjustment method, which solve the technical problems that the existing cable laying position is difficult to control, the cables are easy to accumulate in the corner and the cor...
