Medium wire drawing machine paying-off device

Abstract

The invention relates to a medium wire drawing machine paying-off device. The paying-off machine comprises light rails and a four-wheel rail car arranged on the rails. The four-wheel rail car comprises a bottom frame and three paying-off frames. The bottom frame comprises a base. A first supporting frame and a second supporting frame are movably connected to one end of the base through hinges. The middle of the first supporting frame is in cross connection with the second supporting frame through a first connecting rod. The upper end of the first supporting frame is movably connected with a third connecting frame; the second supporting frame is movably connected with a fourth supporting frame. The third supporting frame and the fourth supporting frame are arranged in a crossed mode, and the crossed positions of the third supporting frame and the fourth supporting frame are connected through a second connecting rod. The three paying-off frames are horizontally erected at the upper ends of the third supporting frame and the fourth supporting frame. An upper limiting locking device is connected between the top of the bottom frame and the bottoms of the three paying-off frames. A linear driving mechanism is arranged on the first connecting rod. An acting rod of the linear driving mechanism is supported onto the second connecting rod. The medium wire drawing machine paying-off device can conduct height adjustment freely without being dismantled. Accordingly, the working efficiency in the loading process is greatly improved.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a wire pay-off device for a middle drawing machine, in particular to a middle drawing machine wire pay-off device that can freely adjust the height of a four-wheel rail car. Background technique [0002] In the prior art middle pulling machine, the four-wheel rail car adopts the lower limit adjustment method without locking device. When the height of the four-wheel rail car needs to be adjusted, the car must be completely disassembled, and then re-adjusted and assembled. Such an adjustment time If it is too long, the adjustment accuracy cannot be guaranteed, which greatly reduces the work efficiency. [0003] Therefore, it is the subject of the present invention to propose a pay-off device for a middle drawing machine. SUMMARY OF THE INVENTION [0004] In order to solve the problems of low productivity and low degree of intelligence in the prior art, every time the height of the four-...
