Abstract

The invention discloses a non-going-forward device for a small-pitch stepper cooling bed, and relates to hot-rolled steel pipe cooling equipment. The invention comprises a fixed rack, a movable rack and a transmission mechanism, wherein the movable rack is supported by two groups of No.I eccentric wheels, and a group of No.II eccentric wheels drive the movable rack through a connecting rod, a lever, a pull rod and a rocker; and a group of eccentric wheels of the two groups of No.I eccentric wheels and the No.II eccentric wheels are coaxial, and a motor is driven by a speed reducer, so that the movable rack moves along the elliptical trajectory. The invention is characterized in that the pull rod between the lever and the rocker is connected with a hydraulic cylinder in series. The invention solves the problems that hot steel pipes bends and deforms to affect the quality of the steel pipes when the steel pipes need to stay on the cooling bed. When the steel pipes stay on the cooling bed, the steel pipes can roll in the rack of the cooling bed and can not go forward, so that the steel pipes can be straightened when being cooled.

Description

Stepping device for stepping cooling bed with small tooth pitch technical field The invention belongs to cooling equipment for hot-rolled steel pipes, in particular to a transmission device for a small-tooth-pitch step-type cooling bed in a seamless steel pipe production unit. Background technique The step-by-step cooling bed with small tooth pitch is installed behind the sizing (reducing) machine, and accepts the hot-rolled steel pipe output by the sizing (reducing) machine, cools it to the required temperature, and transports it to the next station. The small pitch step-type cooling bed device of prior art is shown in Figure 1, comprises: fixed rack 1, moving rack 2 and its transmission mechanism, moving rack 2 is supported by two groups of No. I eccentric wheels 9, by A group of No. II eccentric wheels 3 drives the mobile rack 2 through the connecting rod 4, lever 5, pull rod 6, rocker 7, and adjusting pull rod 8; Coaxial, and driven by the motor through the reducer, t...
