Description

  The present invention relates to an apparatus used for feeding a steel strand wound on a steel wire drum.

  The conventional feeding device is a cable drum feeding device or the like, and is a design device for general use of drums having different drum shapes. Therefore, products that are excessively heavy and require assembly adjustment when used are developed (for example, Patent Documents). (See 1)

  The conventional feeding device will be described below with reference to FIGS. Rollers 10 for placing the drum flange portions are arranged on the front and rear sides of the rectangular frame and are independent on the left and right sides, and various cable drums can be placed for general use by assembling and adjusting the front and rear and left and right positions.

In order to prevent the drum from popping and dropping out during feeding, the 16 pop-out prevention rod is passed through the drum rotation shaft, and the 17 pop-out prevention support plate is adjusted and attached to the drum support base with fixing bolts and nuts according to the drum. Yes.

  In the conventional feeding device described above, the device base is excessive and heavy to use for feeding the wire drum from steel with a small drum outer diameter, and installation adjustment is required for installation. It is unsuitable.

  The present invention is intended to solve the problem of such a conventional configuration, mainly for high efficiency, easy to move and install, no assembly adjustment, simple and lightweight. The purpose is to realize a steel wire feeding device that can be used safely and easily.

  In order to solve the above-described problem, the present invention provides a pair of rotatable rollers on which the left and right flange portions of a steel strand drum are placed, and a height difference of a specified value at one end of one side of a quadrilateral main frame. Thus, the left and right drum flange portions are placed on the rollers at both ends of the main frame, and the wire drum is supported by the steel. In this state, when the wire is drawn from the steel of the wire drum, the rotation axis of the wire drum is rotated in a horizontal state by the rotation of the roller.

  At that time, in order to prevent the steel strand drum from jumping out of the drum support base due to the tension chain when the wire is fed out of the steel, the front and rear rollers provided at both ends of the main frame are set to the front side and the roller shaft mounting position is set to the front side. The height between the front roller shaft and the rear roller shaft and the horizontal line is 10 ° ± 3 ° and the height difference between the front roller shaft and the rear roller shaft is 10 ° ± 3 °. The interval between the drum flange part and the front and rear roller outer diameter contact parts at the time of mounting is used as a reference point, and the drum frame part is attached to the main frame at a value of 75% ± 10% of the mounted drum flange diameter. By providing the specified height difference and spacing, it is possible to prevent the drum from popping out of the drum support base when feeding the steel strand, and there is no need to provide a special pop-out prevention device, making it simple, small and lightweight. .

  In order to prevent contact resistance to the left and right sides of the main frame and falling off by rotating the steel wire drum when feeding the steel strand, it was fixed vertically to the left and right frames in the middle of the rollers at both ends of the main frame. By providing a rotating sphere that rotates horizontally around the shaft, it is lightweight and minimizes pressure breakage, thereby solving these problems.

  In addition, a steel stranded drum can be easily placed on the drum support base, and a detachable slope frame is movable 220 ° around an axis parallel to the upper part of the main frame rear side, and a mounting slope that folds on the upper part of the main frame. Provide convenience for mobile installation.

  As described above, the wire stranding device of the steel strand drum according to the present invention is easy to move and install, requires no special assembly, and can be used safely with improved work efficiency.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a wire stranding device for steel strand drums according to the present invention will be described below with reference to the drawings.

  The steel strand drawing device for a steel strand drum according to the present invention includes a quadrilateral drum support frame 1.

  The steel strand drum support pedestal 1 is a steel strand drum flange part A or C drum on which a rotatable roller 3 is placed on both ends of a quadrilateral main frame 2, and a roller 5 is fed forward. Are arranged on the rear side with a specified height difference and spacing.

  The roller mounting positions on both ends of the main frame are such that the angle between the line connecting the front roller shaft 4 and the rear roller shaft 6 and the horizontal line is a value of 10 ° ± 3 °, and the distance between the front and rear rollers is determined when the drum is mounted. The flange portion, the contact portion G of the outer diameter of the roller and the contact point portion E are set as reference intervals, and are attached to the main frame 2 at an angle and a distance of 75% ± 10% of the mounting drum flange diameter.

  The main frame 2 is provided with left and right frames intermediate between the roller front side 3 and the rear side 5 with rotating balls 7 that horizontally rotate around a shaft in which a fixed shaft 8 is fixed vertically by a fixed shaft mounting bracket 9. Reduces the frame contact resistance to the left and right of the wire drum to prevent it from falling off.

  The steel wire drum support pedestal 1 is movable by 220 ° about a shaft 11 that can be attached and detached in parallel with the frame at the upper rear side of the main frame 2 so that the steel wire drum can be mounted on the support gantry by rolling the drum. The slope frame 10 with a drop-off prevention guard that supports the left and right of the drum flange portion is provided, and is folded over the upper portion of the main frame 2.
