Abstract

The invention provides a steel strand cable-releasing device, which relates to the technical field of steel strand cable-laying equipment, including a fixed bracket, a rotating mechanism, a tensioning mechanism and a locking mechanism; the rotating mechanism is used to drive a disc-shaped steel strand The wire is rotated, so that the end of the disc-shaped steel strand is released; by using the transmission effect of the tensioning mechanism, the disc-shaped steel strand can be kept in a tensioned state during the process of unwinding the cable. , so the steel strand will not roll over on the surface of the drum, and the strands will relax due to the influence of gravity, causing the strands to be entangled; the posture can be adjusted between the first state and the second state through the locking mechanism; It is possible to limit or open the unwinding of the disc-shaped steel strand; it alleviates the steel strand unwinding that exists in the prior art and rolls on the surface of the drum, which is easy to cause damage to the steel strand and affects the efficiency and efficiency of the steel strand unwinding. quality technical issues.

Description

technical field [0001] The invention relates to the technical field of steel strand laying equipment, in particular to a steel strand laying device. Background technique [0002] In order to improve the performance of concrete structures, in the construction process of large-area and long-span concrete structures, it is necessary to apply a certain compressive stress to the concrete structure before it bears the load, so as to offset or reduce the tensile stress generated by the external load. [0003] In the prior art, the prestressed material is mainly a prestressed steel strand, that is, a twisted steel cable made of high-strength steel wires coiled into strands. The steel strand cable is in a coiled state when it leaves the factory, so it needs to be unwound first during installation. A vertical cable-laying device will be used on the construction site, that is, a horizontal axis is set on two supports, and the drum is placed on the horizontal axis to rotate, and the ca...
