Vertical oscillating type tube connecting machine

Abstract

The invention relates to a tube connecting device for a heavy tube, and in particular relates to a cast tube connecting device which is matched with a novel three-station high-efficient centrifuge and has an adjustable height. The tube connecting device is characterized in that the right end of a head bracket is fixed with the top of a big arm; the left end of the head bracket is hinged with the middle of an oscillating idler wheel bracket; the lower end of the oscillating idler wheel bracket is hinged with the left end of a return spring; the right end of the return spring is hinged with theright end of the head bracket; an oscillating idler wheel is hinged with the upper end of the oscillating idler wheel bracket; a fixed idler wheel which forms a V shape together with the oscillating idler wheel, is hinged with the upper end of the head bracket; the oscillating idler wheel and the fixed idler wheel are used for supporting a cast tube; the lower end of the big arm is hinged with a big arm base; the big arm base is fixed with a tube connecting frame; the lower part of the big arm is hinged with a hydraulic cylinder; a driving arm of the hydraulic cylinder is hinged with a hydraulic cylinder base; and the hydraulic cylinder base is fixed with the tube connecting frame. The tube connecting device has the advantages that the height can be conveniently adjusted, the system rigidity is excellent and only one oscillating hydraulic cylinder is needed.

Description

technical field [0001] The invention relates to a heavy-duty pipe connecting device, which is more suitable for a cast pipe connecting device matched with a novel three-station high-efficiency centrifuge and whose height can be adjusted. Background technique [0002] At present, the commonly used heavy-duty pipe connecting devices are divided into two types: non-driven connecting machines and driven connecting machines according to whether there is a driving force, and there are two types of horizontal swing and vertical swing according to the space swing mode. Swing-type connecting device, that is, the connecting arm swings in the horizontal direction, suitable for two-station cast pipe centrifuges (the pulling device is stationary, called the pulling forceps), generally arranged on the right side of the centrifuge; the centrifuge pours the pipe When the tube is pulled out, the connecting device is knocked away from the original working position. When the tube is pulled out...

AI Technical Summary

Problems solved by technology

Practice has proved that this method has the following deficiencies: ① two hydraulic cylinders are required, which are divided into two steps and sequential actions, which is cumbersome; The machine and the extubation trolley collide; ④ When adjusting the height, it is necessary to remove the connecting arm and install it into the spacer, which is inconvenient
