Fig. 1 is the utility model relates to a structural schematic diagram of upward drawing type constant tension pay-off rack.
Fig. 2 is an enlarged view of the slider of fig. 1.
Wherein: the device comprises a pay-off rack 1, a steel wire 2, a tension control system 3, a T-shaped support 4, a front-track top reversing wheel 5, a rear-track top reversing wheel 6, an upper supporting plate 7, a lower supporting plate 8, a sliding block 9, a linear guide rod 10, a linear guide rod sleeve 11, a locking screw 12, a spring 13, an adjusting wheel 14, a reversing wheel 15 and a vehicle platform 16.
Detailed Description
Referring to fig. 1 and 2, the utility model relates to an upward draw formula constant tension pay off rack, it includes the foremost place in the pay off rack 1 on ground, and the winding has steel wire 2 on the pay off rack 1, and steel wire 2 provides the pulling force and the unwrapping wire backward by ride 16.
In order to ensure that the paying-off tension of the steel wire is constant, a set of tension control system 3 is arranged on the paying-off rack 1 and the trolley 18.
The tension control system 3 comprises a T-shaped support 4 standing on the ground, a front-track top reversing wheel 5 and a rear-track top reversing wheel 6 are respectively installed at two ends of a top beam of the T-shaped support 4, and the top reversing wheel 5 and the rear-track top reversing wheel 6 are fixed pulleys.
