The bottom of the pay-off rack 1 is provided with two symmetrical collet supports 11 in the vertical direction, and the front of each collet support 11 is provided with a wire outlet 3; a screw hole site is preset on the vertical support rib on the front surface of the pay-off rack 1, and a screw 5 penetrates through the screw hole site and is connected with an extrusion plate 4 on the side part of the pay-off rack 1; a gear 6, a rack 7, a rocking handle 8 and a line pressing rod 9 are arranged on oblique supporting ribs on two sides of the pay-off rack 1, and a limiting pin 10 is arranged on the gear 6;
further, a steel strand 2 is wound on the pay-off rack 1;
furthermore, a gear 6 is arranged on an oblique supporting rib at each side of the pay-off rack 1, the central shaft of the gear 6 is connected with a rocking handle 8, the gear 6 is meshed with a rack 7, the bottom of the rack 7 at each side of the pay-off rack 1 is connected with two line pressing rods 9, and the two line pressing rods 9 are symmetrically arranged at two sides of the pay-off rack 1; the left side part and the right side part of the steel strand 2 are pressed and fixed through the wire pressing rod 9.
Further, the steel strand coil on the cylindrical pay-off rack 1 is firmly fixed by the two bottom support brackets 11;
further, the pressing plate 4 and the screw 5 are connected and fixed to form a lateral extrusion device, and the front side and the rear side of the steel strand 2 are compressed and fixed through the lateral extrusion device.
Before the coil is placed, the extrusion plate 4 and the wire pressing rod 9 are moved to the outermost side through the adjusting screw rod 5 and the gear 6, and the coil is prevented from being influenced. After the wire coil is placed, the cylindrical steel strand coil is firmly fixed by using two bottom support brackets 11 at the bottom of the pay-off rack 1, so that the wire coil is prevented from rolling or laterally moving; a lateral extrusion device is arranged on the vertical support rib on the front surface of the support, and the extrusion plate 4 can be driven to move by an elastic screw rod 5 so as to adjust the position of the coil in the front-back direction and tightly press the coil from two sides; the wire pressing rod device arranged on the oblique supporting ribs on the two sides of the pay-off rack 1 can be used for manually shaking the rocking handle 8 to drive the gear 6 and the rack 7 to move to adjust the position of the wire pressing rod 9, so that a wire coil can be conveniently compressed in the front and rear directions, and when the position is properly adjusted, the limiting pin can be inserted into the side part of the fixed gear 6 to prevent the rack from moving due to stress.
The utility model has the following advantages:
1. the utility model has the advantages of simple material, simple structure, easy processing, safety and reliability, and the equipped equipment is common material in construction sites.
2. The utility model saves labor force and working hours, and effectively improves the automation level of the whole device.
