Adjustable combined corner pulley device and adjusting method

Abstract

The invention provides an adjustable combined corner pulley device and an adjusting method. The laying device comprises a positioning mounting seat, corner pulleys and a length-adjustable length adjusting piece, wherein the corner pulleys are rotatably mounted on the side plates on the two sides of a pulley support through a rotating shaft, and the rotating shaft is detachably connected with the side plates; and the length adjusting piece is detachably connected between the mounting base and the pulley support. Cable laying positions at the corners can be prevented from being overlapped to theinner sides of the corners, cable laying is ensured to be standard and tidy, safety accidents caused by uneven stress of the bridge are reduced, the operation difficulty of workers is lowered, and the cable laying efficiency is improved; the cable can be conveniently separated from the pulley support, and the defect that a pulley block is difficult to detach after the cable is laid in the prior art is overcome.

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 adjusting method. Background technique [0002] At this stage, when laying large-section cables at corners, the operation is difficult. When laying with conventional corner pulley blocks, the laying position is difficult to control, which causes uneven force on the bridge frame, dangerous operation by personnel, and 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. Contents of the invention [0003] In view of the above situation, the present invention provides an adjustable combined corner pulley device and adjustment method to solve the existing technical problems that the cable laying position is difficult to control, the cables are easy to accumulate at the corner and the corner pu...

Problems solved by technology

[0003] In view of the above situation, the present invention provides an adjustable combined corner pulley device and adjustment method to solve the existing technical problems that the cable laying position is difficult to control, the cables are easy to accumulate at the corner and the corner pulley block is difficult to remove after the cable is laid, by setting the length The adjustment part is convenient to adjust the reserved length of the cable at the corner, avoiding the time-consuming and laborious problem of readjusting the cable length caused by the accumulation of cables at the corner and the insufficient reserved length of the cable length in the prior art; Detachable connection, convenient to separate the cable from the pulley support, and the detachable connection between the length adjustment member, the positioning mounting seat and the corner pulley, which solves the defect that the pulley block is difficult to remove after the cable is laid in the prior art
