Abstract
The invention discloses a method for drawing a prestressed steel stranded wire, which comprises the following steps of: placing a coiled prestressed steel stranded wire on a horizontal support frame, supporting an inner ring of the coiled prestressed steel stranded wire by a support pillar on the support frame; buckling the prestressed steel stranded wire by using a shield with a leading outlet at the center, leading the end head of the prestressed steel stranded wire from the leading outlet; and rotating the support frame in the reverse direction of winding of the prestressed steel stranded wire, and drawing the end head of the prestressed steel stranded wire so that the prestressed steel stranded wire is drawn. In the method for drawing the prestressed steel stranded wire, the support frame is reversely rotated to eliminate internal stress of the prestressed steel stranded wire in the drawing process, and the shield is used for preventing the prestressed steel stranded wire from flying out to accidently hurt people, thus the prestressed steel stranded wire is safer to use and is convenient for operating by workers so that production efficiency can be greatly increased.
Description
Technical field
The present invention relates to a kind of method, relate in particular to a kind of method of the prestressed reinforcement twisted wire that stretches.
Background technology
In industry work progresss such as bridge construction, high-speed railway track plate, it is a most frequently used procedure that the prestressed reinforcement twisted wire is pulled out.Existing drawing process is one simple and easy of a weldering system, and the top opening after placing the prestressed reinforcement twisted wire wherein, covers with weight again, removes the colligation steel band of prestressed reinforcement twisted wire then, and the reinforcing bar twisted wire is slowly pulled out.
The shortcoming of above-mentioned prior art is: when separating steel band, because the internal stress of prestressed reinforcement twisted wire is huge, thereby easily will covers weight and wash out, the reinforcing bar twisted wire that flies out is hurted sb.'s feelings easily; Moreover the staff that this kind mode needs is numerous, and production efficiency is low.
Summary of the invention
The present invention is directed to the drawback of prior art, a kind of method of the prestressed reinforcement twisted wire that stretches is provided.
The method of stretching prestressed reinforcement twisted wire of the present invention comprises the steps:
Step 1 is positioned over the prestressed reinforcement twisted wire of rolling on the horizontal shore, and makes the inner ring of this rolling prestressed reinforcement twisted wire be supported support column stretching on the frame;
Step 2, the protective cover cover that utilizes the center to have fairlead fastens described prestressed reinforcement twisted wire, and the termination of this prestressed reinforcement twisted wire is drawn from described fairlead;
Step 3, with the counter-rotation bracing frame that the prestressed reinforcement twisted wire is reeled, the termination of drawing prestress wire simultaneously, thereby with the prestress steel twist line drawing.
In the step 3 of the method for stretching prestressed reinforcement twisted wire of the present invention, be to utilize motor drive mechanism to drive bracing frame to rotate.
In the method for stretching prestressed reinforcement twisted wire of the present invention, eliminate internal stress in the prestressed reinforcement twisted wire drawing process by the counter-rotation bracing frame, and prevent that by protective cover the prestressed reinforcement twisted wire from flying out and accident is hurted sb.'s feelings, not only use safer, and make things convenient for the workman to operate, can enhance productivity greatly.
Description of drawings
Fig. 1 is the schematic flow sheet of the method for stretching prestressed reinforcement twisted wire of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing, can implement according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, the method for stretching prestressed reinforcement twisted wire of the present invention comprises the steps:
In this step, the prestressed reinforcement twisted wire of rolling is placed, and the prestressed reinforcement twisted wire of this rolling is carried out spacing, pulled out by integral body with the prestressed reinforcement twisted wire that prevents this rolling in the follow-up drawing process.Particularly, it is fixing to be that support column by being arranged on rolling prestressed reinforcement twisted wire inner ring applies with the power of centrifugal direction stretching to the prestressed reinforcement twisted wire.
In this step, the purpose that protective cover is set is to prevent that the prestressed reinforcement twisted wire is stretched and breaks away from bracing frame, therefore, by protective cover is set the prestressed reinforcement twisted wire of rolling is limited in the space between bracing frame and the protective cover, and only draws the termination of prestressed reinforcement twisted wire by the fairlead of protective cover.
In this step, can utilize motor drive mechanism to drive bracing frame and rotate.The counter-rotation that why makes bracing frame reel with the prestressed reinforcement twisted wire its objective is in order to eliminate the internal stress in the prestressed reinforcement twisted wire drawing process.
In the method for stretching prestressed reinforcement twisted wire of the present invention, eliminate internal stress in the prestressed reinforcement twisted wire drawing process by the counter-rotation bracing frame, and prevent that by protective cover the prestressed reinforcement twisted wire from flying out and accident is hurted sb.'s feelings, not only use safer, and make things convenient for the workman to operate, can enhance productivity greatly.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to various suitable the field of the invention fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the present invention is not limited to specific details and illustrates here and describe.
