Vertical follow-up synchronous compressing device for gas cutting

A vertical follow-up synchronous compressing device for gas cutting comprises a connecting support, a fixed adjusting seat connected with a spray gun clamp, a floating sleeve connected with a gas cutting auxiliary trolley, a spring and a rolling wheel seat. The connecting support is in an L shape, the vertical end of the connecting support penetrates through the hollow fixed adjusting seat at the lower end, the connecting support is compressed through a screw, the cross end of the connecting support is fixedly connected with the rolling wheel seat, the upper end of the rolling wheel seat penetrates through a hole in the bottom of the floating sleeve, a boss is arranged at the upper end of the rolling wheel seat, the boss is located in the floating sleeve and is in clearance fit with the floating sleeve, the top of the boss is fixedly connected with one end of the spring, the other end of the spring is fixed to the bottom face of a spring cover, and the spring cover covers the upper end face of the floating sleeve. The vertical follow-up synchronous compressing device is simple in structure, stable and reliable, the cutting distance is adjusted to be consistent along with walking of a rolling wheel, the perpendicularity of a kerf is guaranteed, labor intensity is reduced, and production efficiency is improved.
